The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

In related schemes, most of the photovoltaic solar devices for ships or offshore fields are arranged on the upper deck surface of a special ship, so that the photovoltaic solar devices are easily polluted and damaged, are troublesome to install and disassemble and have poor universality. Or, the photovoltaic solar device is only a few square meters of photovoltaic cell panels, and can only be used as an auxiliary energy source for a part of signal lamps, and is difficult to be used as a main energy source of equipment.

To this end, the following examples of the present application provide a design of a photovoltaic power generation system. In the following embodiments, the direction in which the outer side surface of the top plate of the container faces upward, the direction in which the outer side surface of the bottom plate of the container faces downward, the direction in which the outer side surface of the left wall plate of the container faces leftward, the direction in which the outer side surface of the right wall plate of the container faces rightward, the direction in which the outer side surface of the front end door of the container faces forward, and the direction in which the outer side surface of the rear end wall of the container faces rearward.

Referring to fig. 1, the present application provides a photovoltaic power generation system, including container 1, photovoltaic board 2, switch board 3 and flexible controlling means 4.

The container 1 comprises a roof 11, a floor 12, a left wall panel 13, a right wall panel 14, a front end door 15 and a rear end wall 16. The top plate 11, the bottom plate 12, the left wall plate 13, the right wall plate 14, the front door 15 and the rear end wall 16 enclose the container 1 in a closed state in six directions, i.e., up, down, left, right, front and rear.

The lower edge of the left wall panel 13 is hinged to the left edge of the base panel 12. Thus, after the connection between the upper edge of the left wall panel 13 and the left edge of the top panel 11 is released, the left wall panel 13 can be flipped outwardly and downwardly about its lower edge to open the left side of the container 1, and thus the photovoltaic panel 2 projects outwardly from the left side of the container 1.

After the left wall plate 13 is opened around the upset of its articulated department with bottom plate 12, left wall plate 13 is located the below to the photovoltaic board 2 that stretches out on the left of container 1 to can avoid left wall plate 13 upset to open the back and cover photovoltaic board 2, avoid influencing photovoltaic board 2 and receive illumination and influence generating efficiency.

The lower edge of the right wall panel 14 is hinged to the right edge of the base panel 12. Thus, after the connection between the upper edge of the right wall panel 14 and the right edge of the top panel 11 is released, the right wall panel 14 can be flipped outwardly and downwardly about its lower edge to open the right side of the container 1, and thus the photovoltaic panel 2 projects outwardly from the right side of the container 1.

After the right wall plate 14 is opened around the upset of its articulated department with bottom plate 12, right wall plate 14 is located the below of the photovoltaic board 2 that stretches out to container 1 right side to can avoid right wall plate 14 upset to open the back and cover photovoltaic board 2, avoid influencing photovoltaic board 2 and receive illumination and influence generating efficiency.

In some embodiments, in the case where only the photovoltaic panel 2 is provided in the container 1 and can extend to the left side of the container 1, only the left wall panel 13 may be designed such that the lower edge thereof is hinged to the left edge of the bottom panel 12, so as to enable the left wall panel 13 to be opened by turning to the left.

In the case where only the photovoltaic panel 2 is provided in the container 1 so as to be extendable to the right side of the container 1, only the right wall panel 14 may be designed so that the lower edge thereof is hinged to the right edge of the bottom panel 12, so as to allow the right wall panel 14 to be opened by being turned to the right side.

The front end door 15 is provided at the front end of the container 1. The front end door 15 includes a left door and a right door which can be respectively opened by turning left and right, and after the front end door 15 is opened, the front end door 15 can enter the container 1, so that the equipment in the container 1 can be conveniently checked, maintained, used and adjusted.

Inside the container 1 there are connectors (not shown in the figures).

The connecting piece is used for movably connecting the photovoltaic panel 2, so that the photovoltaic panel 2 can be connected in the container 1 in an unfolding or retracting way. According to the concrete structural style of photovoltaic board 2, the connecting piece can be the articulated shaft that is fixed in container 1, and the connecting piece can also be the pedestal of seting up the hinge hole.

In some embodiments, the connecting element may also be a part of the container, for example, a hinge hole is formed on the inner wall of the container, and the movable connection of the photovoltaic panel 2 is realized through the cooperation of the hinge hole and the hinge shaft on the photovoltaic panel 2.

In some embodiments, the connecting member may even be in various forms such as a sliding rail or a guide sleeve, and a sliding block matched with the guiding rail or a guide rod matched with the guide sleeve is fixedly arranged on the photovoltaic panel 2, so that the photovoltaic panel 2 can be extended and retracted in the container 1.

In some embodiments, the front end door 15 may instead be a non-openable front end wall, the rear end wall 16 may instead be an openable rear end door, or both front and rear end doors may be provided at the front and rear ends of the container 1.

The photovoltaic panel 2 comprises a plurality of photovoltaic modules 21 hinged one to the other.

For example, when the photovoltaic panel 2 comprises only two photovoltaic modules 21, the left edge of one photovoltaic module 21 is hinged to the right edge of the other photovoltaic module 21. Thus, two photovoltaic modules 21 can be folded together by turning them around the hinge, thus saving space. Two photovoltaic modules 21 can be overturned and unfolded around the hinged position, so that the light receiving area is enlarged, and the power generation efficiency is improved. When the two photovoltaic modules 21 are in the intermediate state of folding and unfolding, the cross section of the photovoltaic panel 2 is in a "V" shape.

If the deployable area of the photovoltaic panel 2 needs to be further enlarged, more photovoltaic modules 21 can be hinged in sequence.

A specific folding method for hinging more than two photovoltaic modules 21 together may be that the folding directions of two edge modules hinged on two opposite sides of the same photovoltaic module 21 are opposite.

For example, the photovoltaic panel 2 formed by three photovoltaic modules 21 hinged one after the other has an "N" shape in cross section in the transitional state of unfolding and folding. The photovoltaic panel 2 formed by hinging four photovoltaic modules 21 in sequence has a W-shaped cross section in the unfolding and folding transition states.

Compared with the photovoltaic panel 2 composed of two photovoltaic modules 21, the photovoltaic panel 2 composed of four photovoltaic modules 21 can be doubled in the light receiving area in the unfolded state, and theoretically, the power generation amount can be doubled. Because the container 1 has a large capacity, a plurality of photovoltaic modules 21 which are mutually folded can be accommodated in the container, and then the light receiving area is large after the container is unfolded, so that high power generation capacity can be achieved.

One edge of the photovoltaic module 21 which is positioned at the innermost side in the photovoltaic panel 2 and is far away from other photovoltaic modules 21 is hinged on the connecting piece in the container 1, so that the movable connection of the photovoltaic panel 2 in the container 1 is realized.

In some embodiments, the photovoltaic panel 2 may also comprise only one photovoltaic module 21. After the arrangement, a photovoltaic module 21 is directly or indirectly hinged to the inside of the container 1, and a part or even all of the photovoltaic module can be extended to the outside of the container 1 in a horizontal state, and can be retracted and stored in the container 1 in a vertical state when the photovoltaic module is turned downwards.

In some embodiments, the photovoltaic panel 2 may also be horizontally slidably disposed in the container 1, for example, a sliding block is fixed on the photovoltaic panel and is matched with a sliding rail disposed in the container 1, so that the photovoltaic panel is horizontally slidably disposed in the container. When the photovoltaic panel slides outwards, the photovoltaic panel extends out of the container 1, and when the photovoltaic panel slides inwards, the photovoltaic panel retracts into the container 1.

The photovoltaic panel can also be composed of a plurality of photovoltaic modules, the photovoltaic modules can slide mutually, and the photovoltaic panel can expand or reduce the light receiving area through the mutual sliding of the photovoltaic modules.

With continued reference to fig. 1 and 2, a photovoltaic panel 2 capable of extending and unfolding to the left side of the container 1 and a photovoltaic panel 2 capable of extending and unfolding to the right side of the container 1 are simultaneously provided in one photovoltaic power generation system, so that the space on the left and right sides of the container 1 can be more fully utilized. When the photovoltaic panels 2 are respectively unfolded towards the left side and the right side of the container 1, the shift of the gravity center of the photovoltaic power generation system to one side can be avoided or reduced, and the stability of the photovoltaic power generation system is kept.

Further, an even number of photovoltaic panels 2 are arranged in one photovoltaic power generation system, and the two photovoltaic panels 2 are paired and arranged in bilateral symmetry. For example, two, four or more photovoltaic panels 2 are symmetrically arranged in a photovoltaic power generation system, so that photovoltaic power generation systems with different power generation powers can be designed according to needs.

The control cabinet 3 is fixed in the container 1 and is positioned at the left and right central positions in the container 1. The control cabinet 3 is used for collecting electric energy generated by each photovoltaic module 21 on the photovoltaic panel 2 and controlling the output of the electric energy.

The connection for the movable connection of the photovoltaic panel 2 may in particular be an articulated shaft provided on the control cabinet 3. The articulated shaft can set up in the left and right sides of switch board 3 to articulated photovoltaic board 2 that sets up in the left and right sides respectively.

Referring to fig. 3, the telescoping control device 4 includes a spool 41 and a pull-cord 42.

The reel 41 is rotatably provided at the bottom of the roof panel 11 of the container 1 near the edge, for example, the reel 41 of the telescoping control device 4 for controlling the photovoltaic panel 2 which can be extended to the left side is provided at the bottom of the roof panel 11 near the left side.

One end of the pulling rope 42 is wound on the winding drum 41, and the other end of the pulling rope 42 is fixed on the photovoltaic module 21. Therefore, when the pulling rope 42 is wound around the winding drum 41, the plurality of photovoltaic modules 21, which are sequentially hinged, can be folded and stored in the container 1. When the pulling rope 42 is released from the winding drum 41, the plurality of photovoltaic modules 21 folded with each other can be unfolded to extend out of the container 1.

Under the condition that the photovoltaic panel 2 only comprises one photovoltaic module 21, the other end of the traction rope 42 is fixed on the photovoltaic module 21 far away from the hinged position, and the traction rope 42 can be wound or released through the winding drum 41 to realize the overturning, unfolding or folding control of the photovoltaic module 21.

In some embodiments, the telescoping control device 4 is further provided with a driving device such as a motor for driving the winding drum 41 to rotate, so that the winding drum 41 can be rotated by controlling the driving device, and the photovoltaic panel 2 is driven to be unfolded or retracted by releasing or winding the traction rope 42, thereby realizing automatic control of the photovoltaic panel 2.

One telescopic control device 4 can independently control one photovoltaic panel 2 to be telescopic, and the telescopic control devices 4 with corresponding quantity are arranged according to the quantity of the photovoltaic panels 2 in the photovoltaic power generation system.

In the case where the photovoltaic panel 2 is extended and retracted by translational sliding, the telescoping control device 4 may be further designed to drive the photovoltaic panel 2 to be extended or retracted by a rack and pinion driving mechanism or the like.

The application method of the photovoltaic power generation system in some application scenes is as follows:

when the container is used on a bulk or grocery ship, a plurality of fixed box feet of the container 1 can be added on a hatch cover or a deck. When solar energy is needed, after the container 1 of the photovoltaic power generation system is fixed through the fixed box feet, the left wall plate 13 and the right wall plate 14 of the container 1 are turned over and opened, and the photovoltaic panel 2 is stretched to collect the solar energy for power generation.

When loading and unloading goods at the wharf, the photovoltaic panel 2 is folded and stored in the container 1, and the power generation system can be temporarily hung on the wharf by a crane.

When being used for on the container ship, only need stack this container modular photovoltaic power generation system at the packing box top layer, can utilize solar energy to generate electricity, need not to carry out any transformation, it is very convenient to use.

When being used for on the liquid cargo ship, to oil chemical tanker or liquefied gas ship, because the face pipeline of deck is more, need set up the container foot stand so that arrange this photovoltaic power generation system's container.

The photovoltaic panel 2 is unfolded under the appropriate weather condition to this application modular photovoltaic power generation system, and under the bad sea condition, bad weather or the condition of entering into there being light pollution harm area, draw in photovoltaic panel 2 to container 1 inside, protection photovoltaic panel 2 avoids damaging.

The key components of the modularized photovoltaic power generation system are stored in the container 1, and power can be transmitted to a ship or a matched battery pack through an external interface, so that the modularized photovoltaic power generation system is extremely easy to transport and use. A plurality of the modularized photovoltaic power generation systems can be used in a superposed mode, and the number of containers can be increased or decreased according to specific requirements. The design dimensions of the container 1 and its internally arranged photovoltaic panels 2 can also be changed as desired.
