The invention relates to a power generation device, in particular to a novel fluid power generation device.

[ background of the invention ]

Fluid power generation devices such as wind power generators usually have fan blades mounted on the top end of a spindle connected to a rotating shaft of a generator, and the fan blades drive a main shaft to rotate under the action of wind power, and the movement locus of the main shaft is vertical, so that a driving motor operates. The mechanical load of the traditional wind driven generator acts on the top of the tower pole, and the requirement on the stability of the equipment is high. In addition, the relation of the static force bearing area of the wind driven generator in the moving circular area of the fan blade is roughly as follows: the leaf pressure center-main shaft is 20%, the leaf pressure center-deformation part is 16%, the deformation part is 3%, and the total stress area is 10%.

Improvements to fluid power generation devices, including mechanical improvements and structural improvements, have been sought in the art.

[ summary of the invention ]

The invention aims to overcome the defects of the prior art and provides a novel fluid power generation device which comprises a core shaft sleeve 2 mechanically connected with a main shaft of a generator, wherein a fan blade outer frame 1 is fixedly arranged on the core shaft sleeve 2, the fan blade outer frame 1 comprises a fan blade upper cover 11, a fan blade lower cover 12 and a side shaft 18 which are symmetrical up and down, an upper core shaft hole 14 matched with the core shaft sleeve 2 is arranged in the center of the fan blade upper cover 11, N upper supporting arms 16 are uniformly arranged by taking the upper core shaft hole 14 as the circle center, a lower core shaft hole 15 matched with the core shaft sleeve 2 is arranged in the center of the fan blade lower cover 12, N lower supporting arms 17 are uniformly arranged by taking the lower core shaft hole 15 as the circle center, and the far end parts of each pair of the upper supporting arm 16 and the lower supporting arm 17 which are symmetrical up and down are respectively connected through the side shaft 18 to realize the connection of the fan;

the fan blades 3 are arranged in the fan blade outer frame 1 along the length direction of the edge shaft 18, and the far ends of the fan blades 3 are hinged with the edge shaft 18;

a limiting device matched with the near end of the fan blade 3 is arranged on the core shaft sleeve 2, so that the fan blade 3 can move around the side shaft 18 in a single direction.

In the present invention, the term "distal end" is used to describe, without limitation, the ends of the fan blades or the upper and lower support arms distal from the mandrel sleeve, and correspondingly, their ends facing the mandrel sleeve may be referred to as "proximal ends".

In the present invention, the term "unidirectional movement about the side axis" means that the proximal end of the fan blade is acted upon by a restraining means, and therefore, when subjected to the force of a fluid, can only open in one direction about the side axis and reclose as the direction of the applied force changes.

In the present invention, the limiting device is used to ensure that the fan blade can only be opened around the side shaft 18 in one direction under the stress state. This one-way motion relationship establishes the transmission relationship of the present invention: when the combination of the fan blade outer frame and the fan blade is pushed by the fluid, the fan blade is divided into a stressed fan blade and an unstressed fan blade according to the different positions and stress directions of the fan blades at that time, as shown in fig. 5.

Fig. 5 shows the motion relationship of the fluid power generation device with three blades in the blade frame when the force is applied. When the fluid power generating device receives fluid thrust F, the second fan blade 302 and the third fan blade 303 are in an open state and are less affected by the thrust F, so the second fan blade 302 and the third fan blade 303 in the positions B and C are defined as non-stressed fan blades. Meanwhile, the first blade 301 in the position a is in a closed state because it is restricted by the limiting device, and therefore, the effect of the thrust force F is large, and the first blade 301 in this state is defined as a stressed blade. The thrust F acts on the stressed fan blades, and the first fan blade 301 transmits the stress to the core shaft sleeve to drive the core shaft sleeve to rotate around the shaft and then to the generator main shaft mechanically connected with the core shaft sleeve, so that the generator operates.

Along with the thrust F acts on the stressed fan blade to drive the movement process of the rotation of the mandrel sleeve, the position of the first fan blade 301 is changed along with the thrust F, when the first fan blade moves from the original A position to the B position in the anticlockwise direction, the limiting device does not play a position restriction role on the first fan blade 301 at the moment, the first fan blade 301 is opened under the action of the thrust F, and the first fan blade 301 at the moment is changed from the original stressed fan blade into a non-stressed fan blade.

As the blade frame and the blade combination continue to rotate counterclockwise around the shaft, when the first blade 301 moves to the rotating position D, the first blade 301 is closed under the action of the pushing force F and is limited by the limiting device to be continuously in the closed state, and the first blade 301 becomes the stressed blade again.

Preferably, the power generation device of the present invention further comprises a stabilizing bracket 4. Because dabber sleeve 2 and dabber possess certain length and mounting height, the firm support is used for improving the stability of dabber sleeve and dabber. The stabilizing support 4 comprises a support outer frame 41 and support feet 42, the support outer frame 41 comprises a support upper cover 43 with a mandrel sleeve hole, a support lower cover 44 and a support frame 45 for connecting the support upper cover 43 with the support lower cover 44, the support upper cover 43 and the support lower cover 44 are respectively mechanically connected with the mandrel sleeve 2 through bearings, and the support feet 42 are fixedly connected with the support lower cover 44 and the ground.

In the present invention, N is a natural number and N.gtoreq.3. When N is 3, i.e. blade upper cover 11 is provided with 3 upper support arms, and correspondingly, blade lower cover 12 is provided with 3 lower support arms, so that 3 blades are installed in the blade frame. The angular distance between each blade is 120.

In the present invention, the fan blade includes a fan blade frame 31 and a fan blade 32 fixed on the fan blade frame 31.

In the present invention, according to an alternative embodiment, the position limiting device can be realized by a positioning pin 33 fixed on the mandrel sleeve and a positioning groove matched with the positioning pin 33 and arranged at the proximal end of the fan blade framework 31. Variations and modifications to the spacing device may occur to those skilled in the art in light of the teachings of the prior art.

According to a preferred embodiment, the novel fluid power generation device further comprises a speed change mechanism mechanically connected with the main shaft of the generator.

The novel fluid power generation device also comprises a brake mechanism and/or an energy storage mechanism which are connected with the generator.

The design and manufacture of the speed-changing mechanism, the braking mechanism and the energy-storing mechanism matched with the fluid power generation device are common knowledge of those skilled in the art, and are not described in detail herein.

In the present invention, in order to reduce the self weight of the fan blade, the fan blade is a resin fiber composite fan blade. The skilled person can select a resin fiber composite material with light weight and sufficient strength to manufacture the fan blade according to the teaching of the prior art.

Further, a ceramic bearing can be adopted to realize an underwater corrosion prevention function.

The novel fluid power generation device is suitable for liquid fluid or gaseous fluid environments. The skilled person can select the appropriate size, the number of the fan blades in each fan blade outer frame and the number of the fan blade outer frame groups according to the specific environment so as to adapt to different power generation requirements in the range from below the stratosphere to 200 meters under water.

The novel fluid power generation device can comprise a plurality of groups of fan blade outer frames arranged along the length direction of the mandrel.

The invention improves the installation position of the fan blade into the hinge joint with the side shaft through the brand-new fan blade outer frame design, realizes the state change of the fan blades at different positions under the fluid environment, namely partial fan blades are stressed and limited and are positioned at the stressed fan blades, partial fan blades are not stressed (or stressed less) and are not limited to be non-stressed fan blades, and the stressed fan blades drive the main shaft to rotate, thereby realizing the maximum stress area of hydrodynamics and effectively improving the torque force and the efficiency of the carrier in unit area.

By adjusting the size and the number of the fan blades in the fan blade outer frame, the fluid power generation device is suitable for wind power generation or river, ocean current and ocean current torrent power generation, and the number of the fan blades is adjusted along with the fluid environment, so that the power generation efficiency can be effectively improved. The person skilled in the art can also make appropriate modifications according to the technical solution of the present invention, for example, the device of the present invention is appropriately reduced in size and installed on a vehicle to realize mobile power generation, and is particularly applied to an electric vehicle as a range extender. The fluid power generation device of the present invention can be connected to a power system of an electric vehicle according to a technique that is already known to those skilled in the art.

According to the fluid power generation device, through structural improvement, the arrangement of a mandrel horizontally arranged in a conventional wind driven generator is changed into the arrangement of a mandrel vertically arranged, the stability of the mandrel and mandrel sleeve combination is ensured through the stabilizing support, the construction difficulty is low, the construction is simpler, and common civil construction units can carry out construction.

[ detailed description ] embodiments

The following examples serve to illustrate the technical solution of the present invention without limiting it.

The invention has several modes:

example 1 the device according to the invention is placed vertically in a gaseous or liquid fluid environment

The fluid power plant shown in fig. 1 is placed vertically in a fluid environment. When the power generation device is vertically arranged, the power generation device can be arranged singly or in an array mode according to the power generation scale or engineering indexes.

The fan blade outer frame is shown in fig. 2-3, and includes a fan blade upper cover 11, a fan blade lower cover 12 and a side shaft 18 which are vertically symmetrical, and three fan blades 3 are respectively installed along the length direction of the side shaft 18. As shown in fig. 4, the fan blade 3 includes a fan blade frame 31 and a fan blade 32 disposed on the frame, wherein the fan blade 32 is made of a resin fiber composite material.

The stabilizing bracket 4, as shown in fig. 1 and 3, includes a bracket outer frame 41 and a bracket foot 42, and the bracket outer frame 41 includes a bracket upper cover 43, a bracket lower cover 44 and a bracket rim 45 for ensuring the stability of the vertically arranged mandrel sleeve 2.

In the present embodiment, the size of the fan blade in the gaseous fluid is 10m × 30m, and the rated power of the motor is 500-.

After the main body of the generating set is installed, the mandrel is connected with the belt pulley in a hanging mode, the speed is increased to 6000 revolutions through gear transmission, and a brake, a clutch and a generator are installed. Wherein, the installation of brake, clutch and generator refers to conventional wind power engineering construction teaching.

Compared with the traditional three-blade wind driven generator arranged in the same environment, the specification of the traditional three-blade wind driven generator which is equivalent to a blade with the wind wheel area of 600 square meters needs 14 meters, and the rated power of the matched motor is about 120 kilowatts and is obviously smaller than that of the embodiment.

Furthermore, the power generation device of the present embodiment may be mounted in a matrix manner. The array type installation has the advantages of low unit cost, high total power generation amount and easy maintenance.

EXAMPLE 2 horizontally arranged fluid Power plant

In areas with low winds or weak winds throughout the year, the horizontal arrangement of the fluid power plant of the present invention can be achieved with the aid of high-architecture infrastructure. For example, the top of 2Y-shaped cleat supports on a flange plate at the top end of a tower pole are provided with bearings, a mandrel and a mandrel sleeve are horizontally arranged, a fan blade outer frame and a stabilizing support are arranged to ensure the stability of the mandrel and the mandrel sleeve, and then fan blades are arranged along the mandrel.

Horizontally arranged power plants are generally suitable for less powerful projects, wherein a person skilled in the art can select the appropriate blade specifications depending on the rated power of the motor and the fluid environmental parameters of the installation area. In this embodiment, the blade specification is 1800mm × 8500mm, and the rated power of the motor is 30 kw.

Example 3 inverted arrangement of a fluid power plant according to the invention

Furthermore, when the fluid power plant is arranged in an ocean current environment, the installation of the device of the invention is installed under water upside down, i.e. with the generator on top and the mandrel and mandrel sleeve below the generator, with the aid of a float or raft to assist installation.

When installed upside down, the orientation of the mandrel sleeve may be selected depending on the underwater fluid conditions, for example, vertically or horizontally.

For example, the power generation device is applied under water in a vertical arrangement, and when the fan blade specification is 10m × 30m, the rated power of the motor is 5-10 MW.

Or, similarly, when the generator is used as a torrent generator, the generator is arranged under water in a horizontal arrangement mode, and when the specification of the fan blades is 1800mm multiplied by 8500mm, the rated power of the motor is 200KW-1000 KW.

In summary, the device of the invention is superior to the traditional three-blade wind driven generator in the parameters of various embodiments and the rated power of the generator used. Thanks to the improvement of the fan blade structure, the stressed area of the fan blades of the fluid power generation device is obviously larger than that of the traditional three-blade wind driven generator, so that the torque is obviously larger than that of the traditional three-blade wind driven generator and can reach dozens of times of the torque. The rotating speed of the fan blades of the power generation device is also obviously higher than that of the traditional three-blade wind driven generator calculated by the wind speed lower than 15m/s, so the converted power generation amount is also obviously improved.

In addition, due to the improvement of the shape of the fan blades, the fluid power generation device has the advantages of low gravity center and higher safety.

In conclusion, the vertical generator is adapted to the vertical generator through the improvement of the fan blade structure, compared with the traditional three-blade wind driven generator, the fluid power generation device has stronger stability, the vertical shaft fan blade is not influenced by the wind direction, and in addition, the length of the device is smaller, so that the transportation, the manufacture and the construction are convenient.
