Technical Field

The present invention relates generally to the field of solar energy, and more particularly to the field of solar trackers. For example, it will find advantageous application in the solar field.

Background

Solar energy is now the core energy source for numerous technological innovations. Many countries around the world tend to use this renewable energy on a large scale when energy demand is at its highest.

Whether photovoltaic panels or solar reflectors are used, these solar devices suffer from a number of problems.

One of the main problems is the alignment and adjustment of the platform carrying the solar collector device.

Therefore, it is necessary to align these platforms on the north/south axis and to motorize them in order for the platform to track the movement of the sun in the sky, in order to maximize the solar energy collected.

However, this type of installation presents a major obstacle (i.e. the terrain on which the platform is built). In practice, it is difficult to find a completely flat terrain on which to arrange rows of platforms at very long distances. At present, it is necessary to form them into sets in the face of the necessity to optimize the installation.

furthermore, in the context of reducing costs and imparting synchronicity of platform motion, it is common to provide the same solar tracking drive system for multiple platforms in the same row that conform to precise alignment and thus to flat terrain.

To meet the alignment criteria, the topography of the solar field is managed and built into terraces, resulting in higher additional installation costs and longer additional installation times, thereby reducing the incentive for some countries to invest in this type of technology.

Therefore, current solutions for compensating for ground irregularities are mainly based on constructing the terrain or adjusting the alignment of the reflector rows.

Thus, facing this problem, the current solutions are still very expensive and very complex.

The present invention aims to at least partially solve the above mentioned problems.

■ drive module, comprising at least:

● mobile device, comprising at least:

A platform extending longitudinally in a main direction and comprising at least one solar collector device;

A structure, preferably a frame structure, extending longitudinally in the main direction and supporting the platform;

● a first ground support configured to support the first support arch;

● for driving the movement means in rotation relative to the first ground support.

The solar tracker preferably comprises at least one additional module configured to be driven by the drive module, each additional module comprising at least:

● an add-on mobile device comprising at least:

An additional platform extending longitudinally in an additional direction and comprising at least one additional solar collector device;

an additional structure, preferably an additional frame structure, extending longitudinally in the additional direction and supporting the additional platform;

In one embodiment, the additional ground support comprises at least one and preferably a plurality of additional rollers rotatably mounted, preferably freely rotatably mounted and configured to support the additional support arch extending mainly from the additional ground support to the additional frame structure.

The roller preferably supports the moving means and the additional moving means on its own.

In one embodiment, the rotational kinematic drive is configured to drive, preferably directly drive, the first support arch in a first kinematic motion relative to the first ground support about at least one main axis of rotation.

In one embodiment, said additional ground support comprises additional rotation guide means configured to guide, preferably directly guide, said additional support arch in a second kinematic motion with respect to said additional ground support about at least one additional rotation axis, possibly different from said main rotation axis.

In one embodiment, said kinematic coupling comprises at least one first part and at least one second part, said first part being entirely supported by said movement means of said drive module and said second part being entirely supported by said additional movement means of said additional module.

In one embodiment, the first and second components are adapted to cooperate to:

Driving the additional movement means in rotation around the additional rotation axis when the movement means of the drive module are driven in rotation around the main rotation axis by the kinematic drive means,

Allowing the moving means of the drive module and the additional moving means of the additional module to perform a relative translational movement with respect to each other.

the invention thus makes it possible to produce a solar tracker that can adapt to the static irregularities of the ground on the one hand and to the dynamic irregularities of the ground on the other hand.

In fact, the tracker according to the invention uses a single motorized drive for a plurality of platforms on the same row to transmit the kinematic motion through the medium of at least one kinematic coupling configured to accommodate at least some static and dynamic irregularities.

thus, the kinematic coupling means are able to transmit the rotary motion of the first platform to the additional platform even when their respective axes of rotation are not collinear or even coplanar.

Furthermore, the invention enables to reproduce the movement of the first platform by the additional platform via the kinematic coupling means accurately or closely.

the freedom of the kinematic coupling enables the tracker of the present invention to accommodate the dynamic variations of ground irregularities and thermal expansion and contraction experienced by the structure of the solar tracker.

In one embodiment, the first and second support arches are configured to support the frame structure. In one non-limiting embodiment, the first and second support arches are configured to support the frame structure on their own.

The first kinematic motion is a rotational motion, preferably a rotational motion around an axis parallel to the main direction of the platform of the drive module.

The second kinematic motion is a rotational motion, preferably a rotational motion around an axis parallel to the additional direction of the platform of the additional module.

The arches of the mobile device and of the additional mobile device are contained in planes perpendicular to the main direction and to the additional direction, respectively.

The arches of the mobile means and of the additional mobile means are respectively contained in planes perpendicular to the main axis of rotation and to the additional axis of rotation.

In one embodiment, the centers of rotation of the first and second arches pass through the main axis of rotation.

The main axis of rotation advantageously passes through the center of the ellipse formed by the first and second support arches.

In one embodiment, the additional axis of rotation passes through the centre of rotation of the additional support arch.

The additional axis of rotation advantageously passes through the centre of the ellipse formed by the additional support arch.

By providing a coupling means which is carried entirely by the moving means of two adjacent modules, the invention makes it possible to dispense with an additional structure to be fixed to the ground in order to provide a transmission of motion between these two movements.

The present invention thus provides an effective and stable solution that enables accurate tracking of the sun even on incompletely flat terrain with limited costs.

In another aspect, the invention relates to a solar field comprising a plurality of solar trackers according to the invention.

in another aspect, the invention relates to a solar power plant comprising at least one solar field according to the invention.

Such a device may be, for example, a photovoltaic panel, a solar reflector, a thermal solar panel or a solar concentrator.

It is pointed out here that, in the context of the present invention, the term "kinematic" and its equivalents have the following definitions: all physical characteristics and parameters that can be used to describe the motion of an object in a frame of reference.

In the following description, a "universal joint connection" refers to a hinge between two members having three rotational degrees of freedom. A translationally movable universal joint connection is therefore to be understood as a hinge between two members having three rotational degrees of freedom and having at least one degree of freedom and preferably two degrees of freedom for the translational movement of one member relative to the other member.

Before a detailed review of embodiments of the present invention, optional features that may additionally or alternatively be used are listed below:

In both embodiments, the first and second parts are adapted to cooperate so as to:

Enabling torque transfer between the moving device and the additional moving device.

Allowing a relative translational movement of the moving means of the drive module and the additional moving means of the additional module with respect to each other.

In this type of structure, each structural element is preferably essential to support the maximum load-bearing capacity. For a certain mechanical stress (usually load-bearing capacity) all the trabeculae and preferably all the trabeculae and links are preferably subjected to a traction load.

-in one embodiment, the frame structure and the additional frame structure comprise at least one set of a plurality of joists and at least one set of a plurality of additional joists, respectively, distributed along the main direction and the additional direction, respectively, and interconnecting the first, second and third beams and the first, second and third additional beams, respectively, such that the beams and the additional beams form a first set of a plurality of triangles and a plurality of additional triangles, respectively.

In one embodiment, at least one of the plurality of trabeculae is arranged with respect to the first supporting arch along a diameter of the first supporting arch, preferably defining a diameter portion of the first supporting arch, and at least one of the plurality of additional trabeculae is arranged with respect to the additional supporting arch, preferably along a diameter of the additional supporting arch, and preferably defining a diameter portion of the additional supporting arch.

-in one embodiment, at least some of said triangles and at least some of said additional triangles are contained in a plane perpendicular to said main direction and in a plane perpendicular to said additional direction, respectively.

At least one kinematic coupling is advantageously arranged, preferably eccentrically, with respect to the center of gravity of the additional support arch and with respect to the center of gravity of the second support arch.

as described below, the invention solves in particular the problem of the alignment of the platform and its kinematic coupling on terrain with static and dynamic irregularities.

Indeed, while the terrain may be characterized by a height difference along the north/south axis that varies over a greater or lesser distance relative to the platform, it may likewise be characterized by dynamic irregularities of geological origin having greater or lesser magnitude.

Although the terrain itself does not create the second source of dynamic irregularities to which the solar tracker is subjected, it is created by thermal expansion of the materials from which the solar tracker is constructed.

For example, in a desert environment, the ground temperature may be very high during the day and very low during the night. In addition to accommodating static and dynamic irregularities of the terrain, the present invention also accommodates irregularities of the thermal order.

The invention will now be described with the aid of a number of figures for illustrating embodiments of the invention according to a number of embodiments. Each feature described with reference to a given embodiment is applicable to other embodiments unless otherwise indicated.

We will start with this description in a general illustration of the invention and break it down into four non-limiting examples.

General description

The following paragraphs are intended to present the invention in a general manner and to constitute the basic elements and features of the invention and may be used in a variety of embodiments in general.

These elements and these features must be explained in a manner as applicable as much as possible to the drive module as to the additional module. For example, when the term "module" is used alone, the features and elements of the "module" are common to the drive module and the additional module, as are the terms "platform", "beam", "arch", and "bearing", etc.

As mentioned above, the arrangement of a solar tracker comprising a plurality of modules aligned along the north/south axis is problematic when the terrain does not have almost perfect flatness.

fig. 1 shows the case of such a terrain 2000 comprising varying height differences along the north/south axis. In this figure, a solar tracker 1000 according to one embodiment of the present invention is mounted on the irregular terrain 2000.

The solar tracker 1000 in fig. 1 preferably includes at least one drive module 1100 and a plurality of additional modules 1200, which additional modules 1200 may be referred to as "trackers". Another way of presenting the connection between the drive module 1100 and the further module 1200 is to refer to the drive module 1100 as a "master module" and the further module 1200 as a "slave module", which means that the invention is configured such that the kinematic motion of the drive module 1100 is at least partially transferred to the further module 1200.

It should be noted that these "driver module" and "tracker module" terms are valid for all pairs formed by two consecutive modules. A first module may be a tracker relative to the second module and a driver relative to the third module if the first module is located between the second and third modules arranged at respective opposite sides of the first module. In effect, rotation of the second module drives the first module, which in turn drives rotation of the third module.

It should be noted that in a preferred embodiment, the drive module 1100 and the tracker module 1200 are arranged such that one of the ends of the drive module 1100 faces one of the ends of the tracker module 1200.

In fig. 1, the drive module 1100 advantageously includes a drive system configured to ensure that the drive module 1100 tracks the sun. The drive system is either integrated into the drive module 1100 or mechanically transferred to the drive module 1100.

with respect to the drive module 110, the additional module 1200 is an additional module configured to be driven by the drive module 1100 such that the movement of the sun can be tracked synchronously with the drive module 1100 even when there is a height difference and/or misalignment in the space and/or parallel horizontal planes between the drive module 1100 and the additional module 1200 and even between the additional module 1200 itself.

The drive module 1100 is preferably arranged between two additional modules 1200 as shown in fig. 1 in order to distribute the drive torque throughout the solar tracker 1000.

The invention then relates to a kinematic coupling between the drive module 1100 and the additional module 1200, so that the tracking movement of the drive module 1100 is reproduced by the additional module 1200 in a simple, reliable and relatively cost-effective manner. This kinematic coupling has the advantage developed by the development of the kinematic coupling device 1300 according to the present invention.

Kinematic coupling device

As described above, the kinematic coupling 1300 is configured to enable sharing of at least one kinematic feature between a first kinematic motion effected by the drive module 1100 and a second kinematic motion performed by the additional module 1200.

"kinematic features" and their equivalents advantageously mean all features capable of describing kinematic movements precisely, i.e. angles of rotation, amplitudes of rotation, motion vectors, amplitudes of translation, speeds and accelerations, for example.

Fig. 2a, 2b and 2c show three different views of solar tracker 1000 extending in the north/south direction. In these figures, platforms 1110 and 1210, including solar collector devices 1112 and 1212 (not shown in these figures), are mounted to frame structures 1120 and 1220 having support arches 1130, 1150 and 1230 (not shown in these figures) at each of their ends. For each module 1100, 1200, the platform, the frame structure, and the arch form a mobile device. In one embodiment of the invention, the mobile device rests on ground supports 1140, 1160, and 2140 (not shown in these figures) in each module 1100, 1200.

Fig. 2a is a perspective view of solar tracker 1000. The solar tracker 1000 preferably includes a drive module 1100 and a plurality of additional modules 1200 to form a row.

In one embodiment, the drive module 1100 may be at the beginning or end of a row of modules. This enables convenient maintenance of the drive system.

In another embodiment, the drive module 1100 is between two additional modules 1200.

The drive module 1100 is preferably at the level of the center of the solar tracker 1000 to distribute the drive torque throughout the solar tracker 1000.

in fig. 2a, the kinematic coupling 1300 between the modules of each pair of modules is represented in a somewhat schematic way. A more precise description thereof will be given below preferably by four embodiments.

Fig. 2b is an outline view of solar tracker 1000 from the previous fig. 2a. Here again, platforms 1110 and 1210, frame structures 1120 and 1220 and kinematic coupling 1300 arranged between the modules of each pair of modules are present.

In this figure, the height difference 2100 has been shifted in order to illustrate the adaptability of the invention to terrain 2000.

In fact, in fig. 2b, it is worth noting that the height differences 2100 between the various modules are different, but nevertheless the invention enables to transmit the movement of the driving module 1100 tracking the travel of the sun to each additional module 1200 through the kinematic coupling 1300.

Fig. 2c is a top view of the solar tracker 1000 according to fig. 2a. In the case shown in this figure, the solar tracker 1000 has a quasi-perfect alignment along the north/south axis. In fact, it should be noted that because north/south alignment is selected, solar tracker 1000 according to the present invention must accommodate irregularities in terrain 2000. Thus, the present invention enables maintaining north/south alignment without constructing terrain 2000 while maintaining solar tracker 1000 comprising multiple modules.

In a preferred embodiment, the drive module 1100 comprises at least one moving means (1110, 1120, 1130, 1150), at least one first ground support 1140 and at least one rotational kinematic drive 1141. The add-on module 1200 also comprises at least one add-on moving device (1210, 1220, 1230), at least one add-on ground support 1240 and at least one add-on rotary guide 1241.

The kinematic coupling is preferably supported entirely by the moving means and/or the additional moving means.

The coupling device 1300 advantageously comprises at least one first part 1330 and at least one second part 1340, the first part 1330 being entirely supported by the movement means (1110, 1120, 1130, 1150) and the second part 1340 being entirely supported by the additional movement means (1210, 1220, 1230).

In a preferred embodiment, the first part 1330 of the coupling device 1300 and the second part 1340 of the coupling device 1300 are arranged facing each other.

The invention skillfully enables the alignment of the coupling point between two modules to be adjusted during installation of the solar tracker to be distributed.

Module

Fig. 3a, 3b and 3c show a module according to an embodiment of the invention, which may be a drive module 1100 or an add-on module 1200, depending on whether it comprises a drive system (not shown in these figures). The modules shown in these figures are in a position inclined 60 degrees westward.

Indeed, in one embodiment of the present invention, the drive module 1100 of the solar tracker is distinguished from the add-on module 1200 only by the presence of the drive system. The drive system is advantageously arranged at the level of a ground support 1140 configured to carry support arches 1130. The presence of the drive system of the drive module at ground level enables a reduction in the weight of the module.

Fig. 3a is a perspective view of a module 1100, the module 1100 including, for example, a platform 1110 mounted on a frame structure 1120. The frame structure is a structure comprising in a conventional manner beams or structural parts extending in at least two different directions and fastened to each other.

In the embodiment shown in fig. 3a, each end 1121 and 1122 of the frame structure 1120 is supported by a support arch 1130 and 1150.

In another embodiment as shown in fig. 22a, the frame structure 1120 is supported by one or two support arches 1130 and 1150 arranged between the middle and each of the two ends 1121 and 1122, respectively, of the frame structure 1120.

In another embodiment, the frame structure may be supported by more than two arches.

In one embodiment, as shown for example in fig. 3a and 22a, each support arch 1130, 1150 and 1230 rests on a ground support 1140, 1160 and 1240. The ground supports 1140, 1160, and 1240 comprise a base or foundation that is at least partially anchored in the ground. The base is made of concrete, for example.

In another embodiment, only one of the two support arches 1130 and 1150 rests on ground support 1140.

Thus, the drive module shown in fig. 3a comprises a first support arch 1130 arranged at the level of a portion of the first end 1121 of the frame structure 1120 and a second support arch 1150 arranged at the level of a portion of the second end 1122 of the frame structure 1120.

The first support arch 1130 advantageously rests on the first ground support 1140 and the second support arch 1150 advantageously rests on the second ground support 1160.

In the embodiment shown in fig. 3a, the first ground support 1140 comprises a ground suspension 1170 configured to position the modules 1100 and 1200 in a simple and reliable manner and to help compensate for irregularities in the terrain 2000. The ground suspension 1170 will be described more precisely below.

Fig. 3b is a profile view of the module 1100 from fig. 3a. In which like elements appear. The presence of a portion of the kinematic coupling 1300 in the first embodiment, described immediately below, at each end 1121 and 1122 of the module can be seen more clearly in this figure.

The first end 1121 includes two recesses 1331 of the kinematic coupling 1300 according to the first embodiment of the present invention, and the second end 1122 includes two protrusions 1341 of the kinematic coupling 1300 according to the first embodiment of the present invention.

Each recess 1331 and each protrusion 1341 is configured to mate with each protrusion 1341 and each recess 1331, respectively, of the next module.

Fig. 3c shows the module 1100 as seen according to its main extension. This module 1100 is similar to the module in fig. 3a and 3b, except that the second ground support 1160 rests on a support block 2200, for example made of concrete, formed during installation of the solar tracker 1000. The same structural elements appear in this figure as in the previous figures 3a and 3b.

These links 1125 are advantageously subjected to tensile stresses to increase the mechanical strength of the frame structure 1120.

The two links 1125 crossing substantially at their middle are preferably joined together.

In one embodiment, support arches 1130, 1150 are arranged at the level of each of the ends 1121 and 1122 of the frame structure 1120.

In another embodiment, support arches 1130, 1150 are arranged at the level of at least one of the ends 1121 and 1122 of said frame structure 1120.

in one embodiment, the beam 1123 is mechanically coupled to the support arches 1130, 1150 by a beam/support arch pivot connection 1370. In one embodiment of the present invention, these pivotal connections impart additional degrees of freedom to the frame structure 1120 relative to the support arches 1130, 1150, 1230.

The support arches 1130, 1150, 1230 are advantageously circular and/or circular segment shaped members and/or semi-circular enclosed by the diameter portions 1132, 1152, 1232. Alternatively, the support arches 1130, 1150, 1230 are full ovals and/or elliptical portions.

In one embodiment, the centers of the (circular or elliptical) support arches 1130, 1150, 1230 of the same module 1100, 1200 form a straight line parallel to the main extension direction of the movement means of the module. This line is also parallel to the axis of rotation about which the module's mobile device rotates to track the sun.

In one embodiment, the first beam 1123a is arranged at the level of the middle of the semicircular arched members 1131 and 1151 forming the two support arches 1131 and 1151, and the second and third beams 1123b and 1123c are arranged at the level of the two ends 1132 and 1152 closing the diameter of the arched members 1131 and 1151.

In one embodiment, at least one of the spars 1124 is disposed relative to the first support arch 1130 according to a diameter portion 1132 of the first support arch 1130, and the spar 1124 preferably defines a diameter of the first support arch 1130.

Similarly, and as will be described below, in one embodiment, at least one additional spar 1224 is disposed relative to the additional support arch 1230 along a diameter 1232 of the additional support arch 1230, and the additional spar 1224 preferably defines a diameter of the additional support arch 1230.

As described below, the beams 1123a, 1123b and 1123c may preferably be moved in translation with respect to the support arches 1130 and 1150, i.e. the beams 1123a, 1123b and 1123c may slide with respect to the support arches 1130 and 1150 in the main extension direction of the frame structure 1120.

Fig. 4b and 4c are a top view and a profile view, respectively, of the frame structure 1120 according to fig. 4a. In which like elements appear. The presence of parts of the kinematic coupling device 1300 according to a second embodiment, which will be described below, at each end of the frame structure 1120 can be more clearly noted in this figure.

according to a second embodiment of the invention, said first end comprises three recesses 1331 of three kinematic coupling means 1300 and said second end comprises three protrusions 1341 of three kinematic coupling means 1300. In this second embodiment, only two kinematic couplings 1300 may be sufficient to implement the present invention.

Each recess 1331 and each protrusion 1341 is configured to mate with each protrusion 1341 and each recess 1331, respectively, of the next module.

Fig. 4d is a view of the main extension direction of a frame structure 1120 according to an embodiment. In this figure, the positioning of three recesses 1331 of three kinematic coupling devices 1300 according to a second embodiment of the present invention is shown.

As mentioned above, in a preferred embodiment, the first support arch 1130 and the additional support arch 1230 extend on respective opposite sides of the main direction 1111 and the additional direction 1211, respectively.

Rotational kinematics drive

As described above, in one embodiment, the drive module 1100 includes a rotational kinematic drive 1141. The rotational kinematic drive 1141 is configured to enable, among other things, the drive module 1100 to track the sun's motion in the sky.

In one embodiment, the rotational kinematic drive 1141 is configured to drive the drive module 1100 in rotation about the primary axis of rotation 1141a. The main axis of rotation 1141a corresponds to an imaginary axis extending from the first end 1121 to the second end 1122 of the frame structure 1120 and preferably passes substantially through the center of the diameters 1132 and 1152 of the first and second support arches 1130 and 1150.

For example, in the embodiment shown in fig. 5b, 10b and 10c, the rotational kinematic drive 1141 is arranged at the level of the ground supports 1140, 1160, and preferably at the level of the first ground support 1140 of the drive module 1100.

in one embodiment, said rotary kinematic drive 1141 comprises at least one pinion 1141c arranged at a level lower than said support arch 1130 of said drive module 1100, said support arch 1130 comprising a rack 1141d preferably arranged on the level of the outer surface of said support arch 1130 so as to cooperate with said pinion 1141c. This embodiment is shown, for example, in fig. 17a and 17 b.

In one embodiment, at least one, preferably at least two and advantageously at least three of said pinions 1141c are in mechanical contact with said racks 1141d of said support arches 1130.

In another embodiment, the rotational kinematic drive 1141 includes at least one mechanical system capable of rotating the drive module 1100, and may be one or more cylinders or chains, as non-limiting examples.

In one embodiment, the ground supports 1140, 1160, 1240 may include a brake 1142. The braking device 1142 is configured to brake, preferably using rollers, the support arch 1130 in mechanical contact with the rotational kinematic drive 1141.

Rotary motion guide device

In a preferred embodiment, the ground supports 1140, 1160, 1240 may include rotational motion guides 1161, 1241. The rotary motion guide device 1161, 1241 is configured to guide the support arches 1130, 1150, 1230 in mechanical contact with the rotary motion guide device 1161, 1241 into rotary motion to track the sun's movement in the sky.

In embodiments such as those shown in fig. 8a, 10b, 10c, 12a and 12b, the rotary motion guide 1161, 1241 comprises at least one roller, and preferably at least one upper guide roller 1161a, 1241b and at least one lower guide roller 1161b, 1241c, and preferably at least two upper guide rollers and at least two lower guide rollers. The one or more rollers are mounted for rotation relative to the base of the ground support. The solar tracker 1000 is preferably configured such that the mobile devices 1110, 1120, 1130, 1150 are supported by the rollers, preferably only the rollers. In this way, all the weight of the moving means is preferably transferred to the roller without passing through any other supporting structure, as is generally the case in the prior art. This makes it possible to reduce the weight of the entire tracker and to simplify the entire tracker significantly. The unit cost thereof is also reduced.

The upper guide rollers 1161a, 1241b are arranged at a level above the arched members 1131, 1151, 1231 of the support arches 1130, 1150, 1230, while the lower rollers 1161b, 1241c are arranged at a level below the arched members 1131, 1151, 1231 of the support arches 1130, 1150, 1230 to support, preferably fully support, their weight.

In another embodiment, the rotary motion guide 1161, 1241 includes only two lower guide rollers 1161b, 1241c.

The invention enables the module to be guided in rotation by the specific shape of said support arches 1130, 1150, 1230 and to be supported by the ground supports 1140, 1150, 1240 comprising rotating guide rollers.

Thus, the walls of the support arches 1130, 1150, 1230 form the rolling tracks of the rollers. The rotational axis of the roller remains constant relative to the ground support.

As a non-limiting example, the frame structure comprises at least one, preferably at least two beams.

The frame structure advantageously comprises at least one support arch, preferably at least two support arches.

First embodiment

A non-limiting first embodiment of the present invention will now be described. The features of this first embodiment remain compatible with the features described above and with the features of the embodiments to be described later.

Fig. 5a and 5b show two applications of the invention, more specifically a kinematic coupling 1300 according to this first embodiment.

Thus, fig. 5a is an outline view of a solar tracker 1000 centered on an additional module 1200 located between two additional modules 1200. As mentioned above, this additional module 1200 comprises an additional platform 1210 mounted on an additional frame structure 1220, said additional frame structure 1220 comprising three additional beams 1223a, 1223b and 1223c and two additional support arches 1230 arranged at the level of each end 1221 of said additional frame structure 1220.

Each additional support arch 1230 rests on an additional ground support 1240, said additional ground support 1240 being arranged on an additional ground suspension 1270, said additional ground suspension 127 itself being placed on the support block 2200.

The same support block 2200 may advantageously be configured to receive two ground supports 1140, 1160, 1240.

Additional beams 1224 are arranged with respect to the three additional beams 1223 to form additional triangles, at least some of which extend parallel to each other, preferably in a plane orthogonal to the additional direction 1211.

The additional frame structure 1220 advantageously includes additional linkages 1225. These links 1125 are arranged to interconnect the additional triangles, preferably two by two. These additional links 1125 are advantageously subjected to tensile stresses to increase the mechanical strength of said additional frame structure 1120.

The two additional links 1225 crossing substantially at their middle portions are preferably coupled to each other.

Fig. 5b is a profile view of the kinematic coupling 1300 in this first embodiment. The figure shows a drive module 1100 and an additional module 1200.

The drive module 1100 comprises a platform 1110, the platform 1110 being mounted on a frame structure 1120, the frame structure 1120 comprising a first support arch 1130, the first support arch 1130 resting on a first ground support 1140, the first ground support 1140 being arranged on a first ground suspension 1170 and comprising a rotational kinematic drive 1141.

The rotational kinematic drive 1141 is configured to enable the solar tracker 1000 to track the movement of the sun by directly driving the drive module 1100 to perform a first kinematic movement and indirectly driving the additional module 1200 to perform a second kinematic movement via the kinematic coupling 1330.

The additional module 1220 comprises an additional platform 1210, the additional platform 1210 being mounted on an additional frame structure 1220, the additional frame structure 1220 comprising an additional support arch 1230, the additional support arch 1230 resting on an additional ground support 1240, the additional ground support 1240 being arranged on an additional ground suspension 1270 and comprising an additional rotational movement guiding means 1241.

The additional rotational movement guide 1241 is configured to enable the additional module to track the movement of the sun by guiding the additional module 1200 to perform a second kinematic movement via the kinematic coupling 1300.

In fig. 5b, the same support block 2200 supports the drive module 1100 and the additional module 1200 at the level of the first ground support 1140 and the additional ground support 1240, respectively. It should be noted that the support block 2200 is capable of at least partially compensating for the large level difference between the two modules.

As mentioned above, in a preferred embodiment, said first support arch and said additional support arch are arranged, preferably completely, at a level lower than said platform 1110 and said additional platform 1210, respectively. The expression "at a level lower than … …" means that it is located lower in its projection on the vertical plane. On the other hand, they do not necessarily remain completely identical to the platform.

In a similar and preferred manner, said first ground support 1140 and said additional ground support 1240 are respectively arranged, preferably completely arranged, at a level lower than said platform 1110 and said additional platform 1210.

Said first support arch 1130 and said additional support arch 1230 advantageously extend from said frame structure 1120 and said additional frame structure 1220, respectively, to the ground, preferably over the height of the separation ground and said main rotation axis 1141a and the height of the separation ground and said additional rotation axis 1241a, respectively, at least 70%, advantageously over at least 80%, advantageously over at least 90% thereof. As shown, the height separating the arch from the ground is determined by the ground support, more precisely by the vertical dimension between the ground and the portion of the ground support on which the arch rests (typically the support rollers).

Universal joint connecting piece capable of moving in translation mode

Fig. 6a and 6b show two precise views of the kinematic coupling 1300 according to this first embodiment, said kinematic coupling 1300 being positioned between said drive module 1100 and said additional module 1200.

Fig. 6a is a perspective view of the kinematic coupling device 1300 according to the first embodiment. The kinematic coupling 1300 is formed in this first embodiment by a translationally movable universal joint connection 1350.

In this first embodiment, the kinematic coupling 1300 includes a first member 1330 and a second member 1340.

Each of these components is advantageously fastened to support arches 1150 and 1230. Thus, the first part 1330 is advantageously fastened to the second support arch 1150 and the second part 1340 is advantageously fastened to the additional support arch 1230.

FIG. 6b is a profile view of the translationally movable universal joint connection 1350. In this figure, the first part 1330 preferably comprises a metal claw 1331a, said metal claw 1331a advantageously comprising a slipper 1331a3, said slipper 1331a3 being configured to limit friction and warming between said male and female parts. The slipper 1331a3 is preferably made of metal, preferably bronze, and is advantageously made of any type of material having a low coefficient of friction (such as PTFE for one non-limiting example). A metal tongue 1341a is preferably arranged in this catch 1331a, said metal tongue 1341a at least partially forming the second part 1340 of the translationally movable universal joint connection 1350.

The catch 1331a advantageously comprises any type of mechanical interface (e.g., a thrust ball bearing type) that can limit friction on the tongue 1341a. As a non-limiting example, the jaws 1331a may comprise a metal spring type material, i.e., treated steel or a composite material.

In this manner, a translationally movable universal joint connection 1350 is created. In practice, the tongue 1341a mechanically connected to the additional support arch 1230 is configured to cooperate with the pawl 1331a mechanically connected to the second support arch 1150. In this configuration, the connection 1350 formed in this manner has rotational and translational degrees of freedom: the tongue 1341a is in fact movable in translation in the pawl 1331a, but can also be movable in rotation in the pawl 1331a in the same way as a universal joint. In effect, the translationally movable universal joint connection 1350 allows for a relative angle between the tongue 1341a and the pawl 1331a.

The tongue 1341a may preferably comprise rigid steel.

Surprisingly, this translationally movable universal joint connection 1350, which is created at least in part by the coupling of the pawl 1331a and the tongue 1341a, ensures a high force transfer between the modules while also being very stable. In addition, such translationally movable universal joint connections 1350 allow for relative translational movement of the pawl 1331a and the tongue 1341a along multiple translational axes. In practice, the relative translational movement of the pawl 1331a and the tongue 1341a is not limited to only one axis of translation.

A slipper 1331a3, preferably made of bronze or composite material, intended to reduce friction, is advantageously arranged between said claw 1331a and said tongue 1341a in order to limit the mechanical friction stresses.

The slipper 1331a3 preferably comprises a material having a ductility lower than the ductility of the material or materials comprising the tongue 1341a and/or the pawl 1331a.

Fig. 7a is a cross-sectional view of a translationally movable universal joint connection 1350 in this first embodiment. In this figure, it should be noted that said catch 1331a, that is to say said first part 1330 of said kinematic coupling 1300, comprises an upper part 1331a1 and a lower part 1331a2, said upper part 1331a1 and lower part 1331a2 engaging to form said catch 1331a. The jaws 1331a1 may preferably be constructed of a material that imparts elasticity thereto (e.g., spring steel type or composite material components) while being capable of transmitting forces related to the torque and stresses to which the structure is subjected.

In this figure, the presence of beam/support arch pivot connection 1370 will be noted, said beam/support arch pivot connection 1370 enabling to impart a complementary degree of freedom to each of said modules.

Fig. 7b is a perspective view of the upper part 1331a1 of the catch 1331a. The upper piece 1331a1 of the catch 1331a is preferably a one-piece mechanical component. The lower part 1331a2 of the catch 1331a is advantageously a mirror image of the upper part 1331a1 of the catch 1331a. This enables the production of only one type of component suitable for use as the upper component 1331a1 or lower component 1331a2 in the manufacture of the present invention.

Fig. 7c is a perspective view of the tongue 1341a, the tongue 1341a being configured to be inserted into the pawl 1331a to define a translationally movable universal joint head 1350 in this first embodiment.

Non-limiting examples

Fig. 8a and 8b show the drive module 1100 and the additional module 1200 kinematically coupled by means of two translationally movable universal joint connections 1350 arranged in this first embodiment at the level of the second 1150 and additional 1230 support arches of the drive module 1100, and preferably at the level of the ends of the diameter portions 1152 and 1132 of these additional support arches 1150 and 1230.

Fig. 8a is a perspective view illustrating the second ground support 1160 of the drive module 1100 and the additional ground support 1240 of the additional module 1200. Each of these ground supports 1160 and 1240 advantageously rests on at least one, preferably at least two ground suspensions 1170 and 1270.

Fig. 8b is a top view of fig. 8a without platforms 1110 and 1210. Translationally movable gimbal attachment 1350 is shown collinear with beam 1123 and additional beam 1223. Each beam 1123 and 1223 is advantageously mechanically coupled to at least one support arch 1150 and 1230 by a beam/support arch pivot connector 1370.

In one embodiment, the first beam 1123a of the drive module 1100 is mechanically connected to the arch member 1151 of the second support arch 1150 and comprises a beam/support arch pivot connection 1370 (referred to as a horizontal beam/support arch pivot connection 1371) whose axis of rotation is preferably perpendicular to the plane defined by the platforms 1110 and 1210.

In one embodiment, the first additional beam 1223a of the additional module 1200 is mechanically coupled to the arched members 1231 of the additional support arch 1230 and includes a beam/support arch pivot connection 1370 (referred to as a horizontal beam/support arch pivot connection 1371) whose axis of rotation is preferably perpendicular to the plane defined by the platforms 1110 and 1210.

In one embodiment, the second and third beams 1123b and 1123c are mechanically coupled to the diameter 1152 of the second support arch 1150 and include a beam/support arch pivot connection 1370 (referred to as a vertical beam/support arch pivot connection 1372) whose axis of rotation is preferably contained in a plane parallel to the plane defined by the platforms 1110 and 1210.

In one embodiment, the second additional beam 1223b and the third additional beam 1223c are mechanically connected to an additional diameter 1232 of the support arch 1230 and comprise a beam/support arch pivot connection 1370 (referred to as a vertical beam/support arch pivot connection 1372) whose axis of rotation is preferably contained in a plane parallel to the plane defined by the platforms 1110 and 1210.

Fig. 9a to 9f are different views of a drive module 1100 and an additional module 1200 kinematically coupled by two gimbal connections 1350 movable in translation, inclined at an angle of about 60 degrees to the north/south axis and having a non-zero height difference therebetween.

Fig. 9a is a perspective view of the two modules 1100 and 1200, which feature the translationally movable gimbal connection 1350 on the one hand and the beam/support arch pivot connection 1370 on the other hand.

these connectors 1350, 1370 are all fastened to at least one support arch 1150 and 1230, respectively, said support arch 1150 and 1230 resting on a ground support 1160 and 1240, respectively, said ground support 1160 and 1240 resting on two additional ground suspensions 1170 and 1270, respectively.

It should be noted that the rotational movement guides 1161 and 1241 include respective upper rollers 1161a and 1241b and respective lower rollers 1161b and 1241c.

In this figure, the two modules 1100 and 1200 have a non-zero height difference between them. This difference in height, shown more clearly in fig. 9b, is not a limitation of the present invention on the kinematic coupling between the two modules 1100 and 1200.

As mentioned above, in a preferred embodiment, the first support arch 1130 has two ends fastened to the frame structure 1120, preferably at least to the frame structure 1120 according to the first kinematic motion, such that the first support arch 1130 extends from the second beam 1123b to the third beam 1123c at the level of the first beam 1123a, and the additional support arch 1230 has two ends fastened to the additional frame structure 1120, preferably to the additional frame structure 1120 according to the second kinematic motion, such that the additional support arch 1230 extends from the second additional beam bundle 1223b to the third additional beam 1223c at the level of the first additional beam 1223a.

Fig. 9b is a top view of fig. 9a and enables the illustration of the translational capability of the universal joint connection 1350 which is translationally movable relative to the two modules 1100 and 1200 in this first embodiment.

In one embodiment, once the drive module 1100 is driven to rotate about the primary axis of rotation 1141a, the translationally movable universal joint connection 1350 rotates about the secondary axis of rotation 1320, which enables the additional module 1200 to be guided to rotate about the secondary axis of rotation 1241a by the kinematic coupling.

In one embodiment, the secondary axis of rotation 1320 may be collinear with the main axis of rotation 1141a and/or the additional axis of rotation 1241a.

Indeed, in this figure, translationally movable top gimbal connection 1355 in fig. 9b has a male portion 1341 and a female portion 1331 that are spaced apart from each other while maintaining direct contact.

Thus, in a preferred embodiment, the tongue 1341a is always in contact with the pawl 1331a, and more specifically always in contact with the shoe 1331a3 of the pawl 1331a.

Translationally movable bottom gimbal connection 1354 in fig. 9b has a recess 1331 and a protrusion 1341 near each other.

The two translationally movable universal joint connections 1354 and 1355 perfectly illustrate the translational movement capability of the kinematic coupling 1300 in this first embodiment. Thus, in this first embodiment, the invention enables, preferably by means of two translationally movable universal joint connections 1350, a kinematic coupling of the drive module 1100 and the additional module 1200.

Three beam/support arch pivot connections 1370 are preferably configured to cooperate with two gimbal connections 1350 that are movable in translation so that a better kinematic coupling can be achieved between the two modules 1100 and 1200.

The two ground suspensions 1170, 1270 supporting the ground supports 1160, 1240 optionally provide improved kinematic coupling between the two modules 1100 and 1200 through their mechanical configuration.

Fig. 9c, 9d and 9e are three different views of the misalignment of the axes of rotation 1141a and 1241a of the drive module 1100 and the additional module 1200, and the two modules 1100 and 1200 being kinematically coupled by two kinematic coupling means 1300 according to this first embodiment and tilted at an angle close to 60 degrees. The three views show the same device from three different angles.

Fig. 9c is a perspective view showing the lower roller 1241c and the upper roller 1241b of the additional rotary motion guide 1241. In this figure, the translational movement of the two platforms 1110 and 1210 relative to each other via the two translationally movable gimbal connections 1350 is also shown.

Fig. 9d and 9e are profile views of the device shown in fig. 9 c. It is noted that the height difference existing between the drive module 1100 and the additional module 1200 and the opposite translational movement of the two translatably movable universal joint connections 1350 enable a continuity of the kinematic motion from the drive module 1100 to the additional module 1200. Thus, the coupling between the two modules can be achieved by the two gimbal connections 1350 being translationally movable in this first embodiment.

the kinematic coupling device 1300 in this first embodiment is configured to enable kinematic coupling and synchronous kinematic motion between two modules coupled by at least one kinematic coupling device 1300 in this first embodiment.

The present invention may advantageously include a beam/support arch pivot connection 1370 configured to cooperate with the described kinematic coupling 1300 to enhance the effectiveness of the first embodiment.

The invention can optionally but preferably include ground suspensions 1170, 1270 configured to cooperate with the kinematic coupling 1300 to enhance the effectiveness of this first embodiment.

ground suspension

One embodiment of a ground suspension configured to cooperate with the present invention to improve the kinematic coupling between two modules will now be described.

Figure 10a is a perspective view of a ground suspension 1170 according to a preferred embodiment. The ground suspension 1170 preferably comprises a metal member 1171 having a U-shape. This advantageous shape enables a spring effect and thus a suspension effect to be provided once one limb 1171b or 1171c of the U is disposed on the ground and the other limb of the U supports the ground support 1140, 1160, 1240 of the module 1100, 1200.

In one embodiment, the ground supports 1140, 1160, 1240 rest on only one ground suspension 1170 having a U-shape 1171.

In the preferred embodiment, ground supports 1140, 1160, 1240 rest on two ground suspensions 1170. This makes it possible to provide the ground support with two degrees of freedom of suspension and thus at the same time a better adaptation to irregularities of the terrain 2000 and also an improved kinematic coupling between the two modules.

in fig. 10b, one use of the rotational kinematic drive 1141 and a ground suspension 1170 having a U-shape 1171 is shown. This device 1141, which has been described above, enables the drive module 1100 to be driven in rotation about the main axis of rotation 1141a.

Similarly, in this figure, the brake 1142 described above, and in particular the brake rollers 1142a and 1142b, are also shown.

In another embodiment, a single ground suspension 1170 may be shared by two adjacent modules.

In yet another embodiment, a single component may integrate both ground suspensions 1170 and be shared by two adjacent modules.

In another embodiment, multiple ground suspensions 1170 may be shared by two adjacent modules.

Fig. 10c shows a rotary kinematic drive 1141. This device 1141, which has been described above, enables the drive module 1100 to be driven in rotation about the main axis of rotation 1141a. In the embodiment shown in this fig. 10c, the rotary kinematic drive 1141 includes a rack 1141d configured to mate with a pinion 1141c, not shown in this figure.

An advantageous rotational movement accompanying means 1143 is shown in this figure. The device 1143 is configured to accompany the arcuate member 1131 of the first support arch 1130 in its rotational motion. This accompanying is advantageously accomplished by accompanying rollers 1143a and 1143b. The rotational movement accompanying device 1143 includes at least one upper accompanying roller 1143a and at least one lower accompanying roller 1143b.

Fig. 11a and 11b are views of a ground suspension 1174 of this other embodiment, wherein said ground suspension 1174 is shared by two adjacent modules.

In this embodiment, the common ground suspension 1174 includes a base 1174a, two substantially vertical branches 1174b and 1174c, and two substantially horizontal plates 1174d and 1174e.

The base 1174a of the common ground suspension 1174 rests on ground level and preferably on the support block 2200.

Two substantially vertical branches 1174b and 1174c each support one of two plates 1174d and 1174e.

Each plate 1174d and 1174e is configured to support a ground support 1160, 1240 in accordance with the present invention.

This common ground suspension 1174, preferably metal, by virtue of its shape has a suspension effect at the level of each plate 1174d and 1174e.

Further, as shown in fig. 11b, each panel 1174d and 1174e may be more or less tilted to at least partially compensate for a height difference 2100 between two adjacent modules when the solar tracker 1000 is assembled.

the ground suspensions 1170, 1174 cooperate with the coupling means and allow good rotational transfer between two consecutive modules while enabling greater freedom of movement between the modules.

The ground suspensions 1170, 1174, although working in conjunction with the coupling means, may function independently of each other. Protection of the ground suspensions 1170, 1174 may therefore be required independently of protection of the coupling means.

As a non-limiting example, the tongue comprises at least one material from at least the following materials: an elastic material or a material that imparts elasticity to the system.

Second embodiment

A non-limiting second embodiment of the invention will now be described. The features of this second embodiment remain compatible with the features described above and with the features of the embodiments described later.

Fig. 12a and 12b show the invention, more specifically the application of the kinematic coupling 1300 according to this second embodiment.

Fig. 12a is therefore a perspective view of three kinematic couplings 1300 according to this second embodiment, said three kinematic couplings 1300 being arranged between said drive module 1100 and said additional module 1200.

As previously mentioned, the drive module 1100 comprises a frame structure 1120 and a second support arch 1150 arranged at the level of a second end 1122 of the frame structure 1120. The second support arch 1150 comprises three recesses 1331, the three recesses 1331 being configured to mechanically couple to three protrusions 1341 carried by the additional support arch 1230 of the additional module 1200.

It should be noted that in one embodiment, the additional support arch 1230 does not rest on the ground support 1240. Indeed, in this embodiment, the additional module 1200 comprises only one ground support 1240 arranged at the level of the end of the additional frame structure 1220 opposite to the second ground support 1160 of the drive module 1100. .

The second ground support 1160 advantageously rests on support blocks 2200 similar to those described above.

as shown in fig. 12b, this second ground support 1160 rests on a pivot support 1162, said pivot support 1162 being configured to allow said second ground support 1160, and thus said second support arch 1150, to rotate about an axis of rotation perpendicular to said main axis of rotation 1141a of said drive module 1100. The pivotal support 1162 imparts additional degrees of freedom to the present invention to at least partially compensate for irregularities in the terrain 2000.

As described above for the first embodiment, the kinematic coupling device 1300 according to this second embodiment is configured to enable all the additional modules 1200 of the solar tracker 1000 to track the movement of the sun by kinematically coupling the driving module 1100 and the additional modules 1200.

Universal joint connecting piece capable of moving in translation mode

fig. 13a and 13b are two perspective views of three kinematic coupling devices 1300 according to a second embodiment of the present invention as if transparent. Each kinematic coupling 1300 according to this embodiment comprises a translationally movable universal joint connection 1350. The translationally movable universal joint connection 1350 advantageously includes a first member 1330 and a second member 1340.

In a preferred embodiment, the first member 1330 is preferably configured to receive the second member 1340. The first part 1330 is preferably carried by the drive module 1100. The first member 1330 preferably includes a recess 1331, the recess 1331 being configured to mate with the protrusion 1341 of the second member 1340 carried by the add-on module 1200.

In a preferred embodiment, three gimbal connections 1350 that are movable in translation according to this second embodiment are arranged at the level of the diameter portions 1132, 1152 and 1232 of said support arches 1130, 1150 and 1230.

Fig. 14a, 14b and 14c correspond to cross-sectional views of these translationally movable universal joint connections 1350.

FIG. 14a is a top view of three universal joint connections 1350 that are translationally movable according to a second embodiment. Thus, the figure shows a first, second, and third example 1351, 1352, 1353 of translationally movable universal joint connection 1350.

The recess 1331 is configured to at least partially receive the protrusion 1341 such that the protrusion 1341 is translationally movable along a secondary translation axis 1310 in the recess 1331.

In one embodiment, the secondary translation axis 1310 is an axis coplanar with the main axis of rotation 1141a and/or the additional axis of rotation 1241a.

The translationally movable universal joint connection 1350 according to this second embodiment advantageously comprises a male part 1341 and a female part 1331, said male part 1341 comprising a cylinder mounted on a spherical structure, preferably a hemispherical structure 1341b, said female part 1331 comprising a sheath 1331b, said sheath 1331b being configured to allow translational movement of the cylinder mounted on said spherical structure 1341b along said secondary translation axis 1310 in said sheath 1331b and to allow said universal joint function.

In one embodiment, the translationally movable second gimbal connection 1352 has a recess 1331 in which the depth of said sheath 1331b is reduced relative to the depth of the sheath 1331 of the translationally movable first gimbal connection 1351 and the translationally movable third gimbal connection 1353.

This forms a translationally movable universal joint connection 1350 according to this second embodiment. In practice, the recess 1331 mechanically connected to the frame structure 1120 is configured to cooperate with the protrusion 1341 mechanically connected to the additional frame structure 1220. In this configuration, the connecting member 1350 formed in this manner has rotational and translational degrees of freedom: the spherical part of the male part 1341 can in fact move in the sheath 1331b of the female part 1331 by a translational movement, but can equally move rotationally in the same way as a universal joint.

The spherical portion of the protrusion 1341 may advantageously comprise a material different from the material of which the cylindrical portion of the protrusion 1341 comprises and/or the sheath 1331b of the recess 1331 and/or at least the inner coating of the sheath 1331b comprises to limit mechanical frictional stresses.

Fig. 14b and 14c are cross-sectional views of a translationally movable universal joint connection 1350 according to this second embodiment.

Fig. 14b shows a quasi-perfect alignment of the extension axis of the protrusion 1341 with respect to the extension axis of the recess 1331.

A part of fig. 14c shows a misalignment of the axis of extension of the male part 1341 with respect to the axis of extension of the female part 1331, that is to say between the drive module 1100 and the additional module 1200. This misalignment results in a slight tilt of the protrusion 1341 relative to the recess 1331. This figure makes it possible to clearly illustrate the universal joint function of the translationally movable universal joint connection 1350.

FIG. 14d is a perspective view of the boss 1341 of the second member 1340 of the translationally movable universal joint connector 1350 according to this second embodiment. This boss 1341 preferably comprises a cylindrical form of space extension 1341b, said cylindrical form of space extension 1341b comprising at one of its ends means for fastening it to said additional module 1200, and preferably to said additional frame structure 1220, and at the other of its ends a truncated sphere at the level of the distal portion of said boss 1341.

Fig. 14e is a perspective view of a recess 1331 of a first part 1330 of a translationally movable universal joint connection 1350 according to this second embodiment. This recess 1331 preferably takes the form of a sheath 1331b, one of the ends of said sheath 1331b having, for example, an oblong hole, and the other of the ends of said sheath 1331b comprising means for fastening it to said drive module 1100, and preferably to said frame structure 1120.

Fig. 15a and 15b are perspective views of an additional frame structure 1220 of the additional module 1200 and a frame structure 1120 of the drive module 1100, respectively.

The presence of the protrusions 1341 of the three translationally movable universal joint connections 1350 according to this second embodiment will be noted in fig. 15 a.

As mentioned above, these protrusions 1341 are preferably arranged at the level of the additional diameter 1232 of said additional support arch 1230. In order to be able to distribute torque and mechanical forces, the protrusions 1341 are advantageously arranged equidistantly in sequence.

Thus, one boss 1341 is disposed at the center of the additional diameter part 1232, and the other two bosses 1341 are disposed one at each end of the additional diameter part 1232.

The presence of the recesses 1331 of the translationally movable three universal joint connections 1350 according to this second embodiment will be noted in fig. 15 b.

As mentioned above and as shown in the image of the protrusion 1341 in fig. 15a, these recesses 1331 are preferably arranged at the level of the diameter 1152 of the second support arch 1150 of said drive module 1100. In order to be able to distribute torque and mechanical forces, the recesses 1331 are advantageously arranged in sequence equidistantly so as to coincide with the protrusions 1341. Thus, one recess 1331 is arranged in the center of said diameter portion 1152, while the other two recesses 1331 are arranged one at each end of said diameter portion 1232.

The invention can optionally but preferably include ground suspensions 1170, 1270 configured to cooperate with the kinematic coupling 1300 to enhance the effectiveness of this second embodiment.

Non-limiting examples

Fig. 16a and 16b show a drive module 1100 and an additional module 1200 in one application of the second embodiment of the invention.

In these figures it will be noted that the misalignment between the drive module 1100 and the additional module 1200 can be clearly seen by tilting the platforms 1110 and 1210 towards the west at an angle close to 60 degrees.

Fig. 16a is a profile view illustrating the relative translational movement of the drive module 1100 and the additional module 1200 via the three translatably movable universal joint connections 1350 according to this second embodiment.

As described for the previous first embodiment, and as shown in the top cross-sectional view of fig. 16b, the translationally movable third gimbal connection 1353 has the largest spatial extent, that is to say only the ball portion of the cylinder 1341b of the male part 1341 of said connection 1353 is inserted in the jacket 1331b of the corresponding female part 1331. The translationally movable first universal joint connector 1351 has a minimal spatial extent, that is to say almost all of the cylinders 1341b of the protrusions 1341 of the connector 1353 are inserted in the sheaths 1331b of the corresponding recesses 1331.

in an equivalent manner to the first embodiment, this embodiment enables kinematic coupling from the drive module 1100 to the additional module 1200 even when there are multi-dimensional height differences between the modules of each pair of modules.

As a non-limiting example, the protrusions are fabricated to impart the desired strength and elasticity on the component.

Third embodiment

A non-limiting third embodiment of the present invention will now be described. The features of this third embodiment remain compatible with the features described above.

Fig. 17a and 17b are two views of the invention, more specifically the application of the kinematic coupling 1300 according to this third embodiment.

Fig. 17a is a perspective view of a support arch 1150 and an additional support arch 1230 resting on respective ground supports 1160 and 1240 and kinematically coupled to each other by a kinematic coupling 1300 according to this embodiment.

This kinematic coupling 1300 is advantageously arranged at the level of one of the ends of the diameter of the two support arches 1150 and 1230, which makes it possible to exploit the geometry of the modules and limit the forces generated by the torque when transmitting the motion from one module to the other.

Furthermore, this makes it possible not to prevent the rotation of the support arches 1150 and 1230, when said support arches 1150 and 1230 are driven and/or guided at the level of their ground supports 1160 and 1240, respectively.

In this embodiment, the kinematic coupling 1300 comprises at least one first pivot joint 1332, at least one second pivot joint 1342 and at least one kinematic transmission shaft 1360 configured to mechanically connect said first pivot joint 1332 and said second pivot joint 1342. The first pivot hinge 1332 and/or second pivot hinge 1342 are preferably limited in relative motion and comprise a sliding connection preferably provided by tubes 1332a and 1342a in which kinematic transmission shaft 1361 slides.

The kinematic coupling 1300 according to this third embodiment is advantageously configured to form a cardan type connection between the modules of each pair of modules of said solar tracker 1000.

Fig. 17b is a profile view of the element of fig. 17 a. The difference in height and misalignment of the supports in the space or parallel horizontal plane between the support arch 1150 and the additional support arch 1230 will be more clearly noted in fig. 17 b. This difference in height therefore results in a misalignment between the main axis of rotation 1141a of the drive module 1100 and the additional axis of rotation 1241a of the additional module 1200.

It will be noted in both figures that there is optionally a rack 1141d at the level of said support arch 1150. As described above, this rack 1141d may be configured to cooperate with a pinion 1141c hidden in the kinematic drive 1141 at the level of the ground support 1160, the kinematic drive 1141 being configured to drive the drive module 1100 and thus the support arch 1150 in a first kinematic motion. This first kinematic motion preferably corresponds to the rotation of the drive module 1100 about the main axis of rotation 1141a to preferably track the motion of the sun.

Fig. 18a to 18d are perspective views of the invention, more particularly the application of two kinematic coupling devices 1300 according to this third embodiment.

In this embodiment, two kinematic coupling means 1300 according to the third embodiment are used to kinematically couple the drive module 1100 and the additional module 1200.

These four figures show the two kinematic couplings 1300 from four different perspectives, each kinematic coupling 1300 comprising a first pivot hinge 1332, a second pivot hinge 1342 and kinematic transmission shafts 1361 and 1362.

As described below, said kinematic transmission shafts 1361, 1362 are advantageously configured to be movable in translation with respect to said first pivot hinging means 1332 and said second pivot hinging means 1342.

As shown in these figures, the two support arches 1150 and 1230 remain kinematically coupled by the two kinematic coupling means 1300 in the presence of a difference in height.

In this embodiment, both kinematic couplings 1300 are arranged at the level of one end of the diameter of each support arch 1150 and 1230.

Thus, each support arch 1150 and 1230 comprises at the end of its diameter a pivot articulation 1332, 1342, said pivot articulation 1332, 1342 being configured to receive a kinematic transmission shaft 1361, 1362 that mechanically connects itself to a double pivot articulation arranged on the opposite support arch.

The presence of two tubes 1332a and 1342a, each mechanically connected to at least one pivot hinge 1332 and 1342, will be noted in fig. 18c and 18 d.

These tubes 1332a and 1342a are respectively configured to receive the kinematic transmission shafts 1361 and 1362 (also referred to as "moment arms") to mechanically connect them to the pivot hinges 1332 and 1342, respectively, while enabling translational movement thereof through the tubes 1332a and 1342a, respectively.

In a preferred embodiment, the translational movement of the kinematic transmission shafts 1361 and 1362 through the tubes 1332a and 1342a, respectively, enables the establishment of a kinematic coupling between the two modules during the adjustment phase of the solar tracker. Once this adjustment phase has been completed, the translational freedom of one of the two motion-transmission shafts 1361 and 1362 is eliminated.

More generally, in a preferred embodiment, once the adjustment phase has ended, the degrees of freedom of one of the two coupling devices 1300 shown in fig. 18a and 18b are eliminated. Thus, only one of the two coupling devices 1300 in this embodiment continues to have all of its degrees of freedom. Thus, the solar tracker is configured to eliminate at least one and preferably all degrees of freedom of some and preferably only one of the kinematic coupling means.

moreover, in both figures, said first pivot hinge means 1332 comprise at least one hinge 1332b mechanically connecting said tube 1332a and the arched member 1151 of said second support arch 1150.

Moreover, in both figures, the second pivot hinge 1342 comprises at least one hinge 1342b mechanically connecting the tube 1342a and an additional arched member 1231 of the additional support arch 1230.

As in the first and second embodiments, the kinematic coupling device 1300 in the third embodiment is configured to enable all the additional modules 1200 of the solar tracker 1000 to track the movement of the sun by kinematically coupling the driving module 1100 and the additional modules 1200.

Pivot joint and kinematic transmission shaft

Fig. 19a and 19b are two perspective views of a first pivot hinge arrangement 1332 comprising a tube 1332a and a hinge 1332b and mechanically connected to the arcuate member 1151 of said second support arch 1150.

In fig. 19a, said first kinematic transmission shaft 1361 is inserted in said first pivot hinging means 1332. The kinematic transmission shaft 1361 advantageously has a diameter slightly smaller than the inner diameter of the tube 1332a so as to be able to slide inside it. This sliding therefore provides translational mobility to the kinematic coupling 1300 of this third embodiment.

In fig. 19b, only the first pivot hinge arrangement 1332 with said tube 1332a and said hinge 1332b is shown. This hinge 1332b enables said first kinematic transmission shaft 1361 to rotate about two mutually perpendicular axes.

Non-limiting examples

Fig. 20a, 20b and 20c are three views of an application example of the third embodiment of the present invention.

Fig. 20a is a top view of fig. 20c, fig. 20c is a perspective view in part thereof, and fig. 20b is a sectional view of the same.

In these three figures, there is a height difference between the drive module 1100 and the additional module 1200. This difference in height causes a misalignment of the axes of rotation 1141a and 1241a of each of the modules 1100 and 1200, in this third embodiment a kinematic coupling 1300 is used to enable the additional module 1200 to track the sun's movements in the sky in a synchronized manner to the rotation of the drive module 1100 about its main axis of rotation 1141a.

The three figures also make it possible to reinforce the adaptability and the freedom of the two kinematic couplings 1300.

the invention can optionally but preferably include ground suspensions 1170, 1270 configured to cooperate with the kinematic coupling 1300 to enhance the effectiveness of the third embodiment.

fourth embodiment

A non-limiting fourth embodiment of the present invention will now be described. The features of this fourth embodiment remain compatible with the features described above. Accordingly, all of the features, functions, and advantages described with reference to the foregoing embodiments are combined and applied to the following embodiments.

Fig. 21a and 21b show two applications of the invention, more specifically the kinematic coupling 1300 in this fourth embodiment.

Fig. 21a is an isometric view of two additional modules 1200 having a non-zero height difference with respect to each other. The two additional modules 1200 are kinematically coupled to each other by two kinematic coupling means 1300.

Fig. 21b is an outline view of solar tracker 1000 based on two additional modules 1200. As described above, each of these additional modules 1200 includes an additional platform 1210 mounted on an additional frame structure 1220 that includes three additional beams 1223a, 1223b, and 1223c and two additional support arches 1230.

In this fourth embodiment, the two additional support arches 1230 are arranged between the middle and the two ends of the additional frame structure 1220 or on the middle and the two ends of the additional frame structure 1220. In the preferred embodiment, each additional support arch 1230 is disposed at a location between 1/3 and 1/2 (inclusive of end points 1/3 and 1/2) that separates one end of the additional frame structure 1220 from its middle.

This positioning of the support arch with respect to the frame structure and the kinematic coupling means makes it possible to reduce the mechanical forces to which the solar tracker is subjected, making it less costly to manufacture and easier to assemble.

This also makes it possible to maintain an integral structure of each beam.

As previously described, each additional support arch 1230 rests on an additional ground support 1240, which additional ground support 1240 can optionally be arranged on an additional ground suspension 1270 (not shown), which additional ground suspension 1270 itself optionally rests on a support block 2200 (not shown).

In an embodiment compatible with the previous one, each support arch may rest on an adjustment system for the angular blade to compensate for the height differences and ensure a functional clearance and enable the female part of the kinematic coupling means to remain well aligned with the facing male part.

The kinematic coupling of the preceding embodiment is compatible in a particularly advantageous manner with the positioning of the support arches with respect to the frame structure of the fourth embodiment.

Fig. 22a is a perspective view of a frame structure 1120 including a first end 1121 and a second end 1122. As described above, support arches 1130, 1150 are disposed between the middle of the frame structure 1120 and each of the ends 1121 and 1122 of the frame structure 1120.

The support arches 1130, 1150, 1230 have a similar shape to the previous embodiments and may be closed by a diameter portion. In this fourth embodiment, the diameter is preferably formed by the trabeculae 1124, 1224 of said frame structures 1120, 1220.

In fig. 22b, said additional support arch 1230 rests on an additional ground support 1240 similar to the ground support of the previous embodiment.

In fig. 22c, the additional support arch is in the form of a rolling bar configured to cooperate with an additional rotational kinematic guide (not shown).

Universal joint connecting piece capable of moving in translation mode

Fig. 23a, 23b, 24a and 24b are views of the kinematic coupling 1300 according to this fourth embodiment positioned between the drive module 1100 and the additional module 1200.

Fig. 23a and 23b are two perspective views of the kinematic coupling device 1300 according to the fourth embodiment. In the same manner as in the first embodiment, the kinematic coupling 1300 is formed by a translationally movable universal joint connection 1350.

In this fourth embodiment, the kinematic coupling 1300 includes a first member 1330 and a second member 1340.

Each of these components is advantageously fastened to the beams 1123 and 1223. Thus, the first part 1330 is advantageously fastened to the beam 1123 of the frame structure 1120 of the drive module 1100, while the second part 1340 is advantageously fastened to the additional beam 1223 of the additional frame structure 1220 of the additional module 1200.

In fig. 23b, it will be noted that the drive module 1100 and the additional module 1200 are kinematically coupled by two kinematic coupling means 1300, each of the kinematic coupling means 1300 comprising a translationally movable connection 1350 at least partially formed by a recess 1331 and a projection 1341.

In fig. 24a and 24b and in a similar way to the first embodiment, the first part 1330 preferably comprises a metal claw 1331a, the metal claw 1331a advantageously comprising a slipper 1331a3, the slipper 1331a3 being configured to limit friction and warming between the protrusion 1341 and the recess 1331. The slipper 1331a3 is preferably made of metal, preferably bronze, and advantageously of any type of material having a low coefficient of friction (e.g., PTFE). A metal tongue 1341a is preferably arranged in this catch 1331a, said metal tongue 1341a at least partially forming the second part 1340 of the translationally movable universal joint connection 1350.

The catch 1331a advantageously comprises any type of mechanical interface (e.g., a thrust ball bearing type) that makes it possible to limit the friction on the tongue 1341a. As a non-limiting example, the jaws 1331a may comprise a metal spring type material, that is, treated steel or a composite material.

This results in a translationally movable universal joint connection 1350. In practice, the tongue 1341a of the additional beam 1223 mechanically connected to the additional frame structure 1220 is configured to cooperate with the pawl 1331a of the beam 1123 mechanically connected to the frame structure 1120. In this configuration and as in the first described embodiment, the connection 1350 formed in this manner has rotational and translational degrees of freedom: in practice, the tongue 1341a can move translationally in the pawl 1331a and can move rotationally in the pawl 1331a in the same manner as a universal joint. In effect, the translationally movable universal joint connection 1350 enables a relative angle between the tongue 1341a and the pawl 1331a.

The tongue 1341a may preferably comprise rigid steel.

Surprisingly, this translationally movable universal joint connection 1350 created at least in part by the coupling of the pawl 1331a and the tongue 1341a provides for a higher force transfer between the modules while also being very stable. In addition, such translationally movable universal joint connections 1350 enable relative translational movement of the pawl 1331a and the tongue 1341a along multiple translational axes. In practice, the relative translational movement of the pawl 1331a and the tongue 1341a is not limited to one axis of translation.

A slipper 1331a3, preferably made of bronze or composite material, intended to reduce friction, is advantageously arranged between said claw 1331a and said tongue 1341a to limit the mechanical friction stresses.

The slipper 1331a3 preferably comprises a material having a ductility lower than the ductility of the material or materials comprising the tongue 1341a and/or the pawl 1331a.

FIG. 24b is a profile view of a translationally movable universal joint connection 1350 of this fourth embodiment. It is to be noted that in this figure said claw 1331a, i.e. the first part 1330 of said kinematic coupling 1300, comprises an upper part 1331a1 and a lower part 1331a2, said upper part 1331a1 and lower part 1331a2 combining to form said claw 1331a. The jaws 1331a1 may preferably be constructed of a material such as a spring steel type or composite material assembly that imparts elasticity thereto while being capable of transmitting forces related to the torque and stresses to which the structure is subjected.

As a non-limiting example, the tongue comprises at least one material from at least the following materials: an elastic material or a material that imparts elasticity to the system.

Fig. 25a and 25b are two perspective views of the pawl 1331a in this fourth embodiment. For the first embodiment, the upper piece 1331a1 of the catch 1331a is preferably a one-piece mechanical component. The lower part 1331a2 of the catch 1331a advantageously corresponds to a mirror image of the upper part 1331a1 of the catch 1331a. This enables production of only one type of component that can be used as the upper component 1331a1 or lower component 1331a2 during production of the present invention.

This fourth embodiment therefore differs from the first in that the support arches are arranged between the middle and the ends of each frame structure and preferably at a distance from the middle, preferably between 1/3 and 1/2 (including end points 1/3 and 1/2) of the half-length of the frame structure.

In this fourth embodiment, each kinematic coupling 1300 is carried by the frame structures 1120 and 1220. The fourth embodiment gives the solar tracker 1000 the same degree of freedom of movement as the first embodiment described above gives the solar tracker 1000.

Examples of embodiments of cantilevered frame structures

A non-limiting embodiment of the invention will now be described in which the frame structure is cantilevered. The features of this embodiment remain compatible with the features described above. Accordingly, all of the features, functions, and advantages described with reference to the foregoing embodiments may be combined and applied to the following embodiments.

Fig. 21a and 21b show two additional modules 1200 comprising platforms 1210, each platform 1210 being mounted on a frame structure 1220 cantilevered from a ground support 1240.

In one embodiment, each additional support arch 1230 is arranged at a distance L3 from the nearest end 1221 of the additional frame structure 1220, wherein L3 is at least equal to 1/10, preferably 1/5 and advantageously 1/3 of the distance separating the two ends 1221 of the additional frame structure 1220 in the additional direction.

Fig. 22a is a perspective view of a frame structure 1120, said frame structure 1120 being configured to be cantilevered from a first ground support 1140 and a second ground support 1160 by means of a first support arch 1130 and a second support arch 1150, said first support arch 1130 and said second support arch 1150 each being arranged at a distance from a first end 1121 and a second end 1122 of said frame structure 1120. Thus, the first and second support arches 1130, 1150 are disposed between the middle of the frame structure 1120 and each of the ends 1121, 1122 of the frame structure 1120.

In one embodiment, the first support arch 1130 is disposed at a distance L1 from the first end 1121 of the frame structure 1120 and the second support arch is disposed at a distance L2 from the second end 1122 of the frame structure 1120, wherein L1 and L2 are at least equal to 1/10, preferably 1/5 and advantageously 1/3, of the distance separating the first end 1121 and the second end 1122 of the frame structure 1120.

The support arches 1130, 1150, 1230 have a similar shape to the previous embodiments and may be closed by a diameter. In this embodiment, the diameter is preferably formed by the trabeculae 1124, 1224 of the frame structure 1120, 1220.

in addition to this, this cantilevered arrangement enables each module to effectively withstand both static and dynamic mechanical stresses.

The invention is not limited to the described embodiments but encompasses any embodiments within the scope of the claims.
