[0028] For the above-mentioned containerized solar power generation device, the panel folding drive device includes left and right symmetric sector gears, namely a left sector gear and a right sector gear, and a panel folding transmission mechanism for driving the two sector gears to swing synchronously; the panel folding transmission mechanism is arranged on the side frame and includes two driving gears respectively meshing with the two sector gears; the left sector gear is fixed on the left cross arm 2 or the left cross arm 1 hinged on the side frame, and the center line of the left sector gear coincides with the center line of the hinge of the left cross arm 2 or the left cross arm 1 and the side frame; the right sector gear is fixed on the right cross arm 2 or the right cross arm 1 hinged on the side frame, and the center line of the right sector gear coincides with the center line of the hinge of the right cross arm 2 or the right cross arm 1 and the side frame.

[0029] For the above-mentioned containerized solar power generation device, the panel folding transmission mechanism includes a driving shaft 1 extending to both left and right sides rotatably arranged on the top frame. Both ends of the driving shaft 1 are fixed with driving sprockets. Driven sprockets respectively driven by each driving sprocket through a chain are rotatably arranged on driven sprocket shafts, and the driven sprocket shafts are fixed on the side frame. Each driven sprocket and a driving gear are coaxially and fixedly connected.

[0030] The above-mentioned containerized solar power generation device further includes a track folding drive device for driving two synchronously rotating gears on the left and right to swing synchronously but in opposite directions.

[0031] The above-mentioned container-type solar power generation device, the track folding drive device includes a driving shaft 2 that is rotatably set on the base frame and extends to the left and right sides. The two ends of the driving shaft 2 are respectively connected to two driven synchronous gears through a gear transmission device. The two driven synchronous gears are fixed on the left longitudinal rod 1 and the right longitudinal rod 1 hinged to the cross bar fixed to the base frame, or fixed on the left longitudinal rod 2 and the right longitudinal rod 2 hinged to the cross bar fixed to the base frame.

[0032] In the above-mentioned container-type solar power generation device, when the photovoltaic panel or photovoltaic panel frame is in a vertical state, the foldable solar cell panel mechanism is located in the space surrounded by the bottom frame, side frame and top frame of the container; when the track unit is in a folded state, the foldable track is located in the space surrounded by the bottom frame, side frame and top frame of the container.

[0033] The above-mentioned container-type solar power generation device has guide rails arranged on the upper parts of part of the left longitudinal rod 1, the left longitudinal rod 2, the right longitudinal rod 1, and the right longitudinal rod 2, and the lower ends of the two cross arms are rotatably connected to guide wheels that can roll along the guide rails; when the track unit is in the unfolded state and the photovoltaic panel or photovoltaic panel rack is in a vertical state, no guide rail is arranged on the left track or the right track that is opposite to the guide wheel in the foldable solar panel mechanism.

[0034] The beneficial effects of this patent are:

[0035] The foldable track can be quickly unfolded or folded. Since there is a synchronization mechanism between the left longitudinal rod one end and the left longitudinal rod two end in the foldable track, and there is a synchronization mechanism between the right longitudinal rod one end and the right longitudinal rod two end, the left longitudinal rod one and the left longitudinal rod two can swing synchronously but in opposite directions, and the right longitudinal rod one and the right longitudinal rod two can swing synchronously but in opposite directions. Therefore, the left longitudinal rod one and the left longitudinal rod two can be quickly folded or unfolded to form the left track, and the right longitudinal rod one and the right longitudinal rod two can be quickly folded or unfolded to form the right track. When the foldable track is in the folded state, the left longitudinal rod one, the left longitudinal rod two, the right longitudinal rod one, the right longitudinal rod two, and the cross bar are all parallel to each other, small in size, and can be moved quickly.

[0036] The synchronous mechanism adopts meshing synchronous gears, and the structure is simpler.

[0037] Each track unit also includes a left auxiliary rod 1, a left auxiliary rod 2, a right auxiliary rod 1, and a right auxiliary rod 2, which can make the shape change symmetrical on the left and right, and the foldable track can be unfolded or folded more quickly and efficiently.

[0038] The left auxiliary rod 1 and the left longitudinal rod 1, the left auxiliary rod 2 and the left longitudinal rod 2, the right auxiliary rod 1 and the right longitudinal rod 1, and the right auxiliary rod 2 and the right longitudinal rod 2 are all staggered in the axial direction of the synchronous gear. In the folded state, the left longitudinal rod 1 and the left longitudinal rod 2 can be adjacent to each other, and the right longitudinal rod 1 and the right longitudinal rod 2 can be adjacent to each other, thereby reducing the folded size.

[0039] The bottom of the crossbar is provided with rollers that can roll on the ground, which can reduce the resistance when the folding track is unfolded or folded.

[0040] Folding solar panel mechanism, the first cross arm and the second cross arm rotate relative to their middle hinge points. The angle between the lower rear part of the first cross arm and the upper rear part of the second cross arm decreases from large to small within the interval (0°, 180°). The photovoltaic panel or the photovoltaic panel rack can change from the vertical (folded) state to the horizontal state or the inclined state (unfolded state); in the vertical (folded) state, the distance between the photovoltaic panels or the photovoltaic panel racks is very small, and the overall size is small, which is convenient for movement, loading and unloading. In the horizontal state or the inclined state, the photovoltaic panel is in the working state. By changing the angle between the two cross arms, the angle of the photovoltaic panel or the photovoltaic panel rack can be changed, so as to adjust the angle between the photovoltaic panel and the sun rays, so that the photovoltaic panel is always at the angle with the highest power generation efficiency.

[0041] In each photovoltaic panel unit, there are two first cross arms, two second cross arms and two connecting rods arranged symmetrically on the left and right, and the structure is more stable and reliable. The two sides of the photovoltaic panel or the photovoltaic panel rack are directly or indirectly connected to the connecting rod, the first cross arm or the second cross arm respectively, and the folding or unfolding is more flexible.

[0042] The photovoltaic panel or the photovoltaic panel rack is located above the left and right cross arms or between the left and right cross arms, so that the photovoltaic panel will not be blocked, the solar energy can be reused, and the photovoltaic panel will not be unevenly illuminated due to blockage, ensuring the service life of the photovoltaic panel.

[0043] The unfolding or folding of the folding track, and the folding or unfolding of the photovoltaic panel or the photovoltaic panel rack can be directly operated manually without external force. In order to improve the operation efficiency and save labor, a track folding drive device and a panel folding drive device are installed.

[0044] The track folding drive device adopts a second driving shaft, and both ends of the second driving shaft are respectively connected to two driven synchronous gears through a gear transmission device, with a simple structure and ensuring the synchronous folding and unfolding of the left track and the right track.

[0045] The panel folding drive device adopts two sector gears, a first driving shaft rotatably arranged on the top frame and extending to the left and right sides, a driven sprocket shaft fixed on the side frame, etc., making full use of the space of the container and preventing the panel folding drive device from interfering with the folding or unfolding of the photovoltaic panel or the photovoltaic panel rack.

[0046] When the photovoltaic panel or the photovoltaic panel rack is in the vertical state and the track unit is in the folded state, the folding solar panel mechanism and the folding track are both located in the space surrounded by the bottom frame, side frame and top frame of the container, which is convenient for transporting and moving the entire container-type solar power generation device.

[0047] The lower ends of the two cross arms are rotatably connected to guide wheels that can roll along the guide rails, further reducing the resistance when the cross arms are folded or unfolded, and also guiding the movement of the lower ends of the cross arms. However, in order to prevent the guide wheels from interfering with the change between the folded state and the unfolded state of the track unit when the photovoltaic panel or the photovoltaic panel frame is in the vertical state, no guide rails are provided on the left track or the right track that is vertically opposite to the guide wheels in the foldable solar panel mechanism.

[0048] The present invention provides a foldable solar panel mechanism photovoltaic panel frame that is convenient to deploy and has a low cost.

[0049] The foldable solar panel mechanism photovoltaic panel frame includes a first cross arm and a second cross arm, which are hinged in the middle, and includes a connecting rod that is hinged to the lower half of the first cross arm, and the other end of the connecting rod is hinged to the photovoltaic panel frame. Multiple groups of the above structures are connected end to end to form multiple groups of structures.

[0050] Any end of the two cross arms can be used as a fixed end, which can be set to slide on the track, or one end of one cross arm can be fixed and the other end of the other cross arm can slide.

[0051] By changing the included angle between the two cross arms, the angle of the photovoltaic panel frame can be changed. When it is necessary to use the photovoltaic panel to generate electricity, the horizontal included angle between the two cross arms is reduced, and driven by the connecting rod, the photovoltaic panel gradually turns up until the required angle is reached. Changing the included angle of the cross arms can also meet the included angle between the photovoltaic panel and the sun rays. Increasing the included angle of the cross arms can retract the photovoltaic panel.

[0052] The structure of the present invention is simple. By only changing the included angle of the cross arms, the angles of all photovoltaic panels can be changed. Moreover, when unfolded, the photovoltaic panels are located above the cross arms or between the left and right cross arms, and there are basically no components blocking the photovoltaic panels, which can reuse solar energy, and the blockage will cause uneven illumination. The absence of blockage ensures the service life of the photovoltaic panels.

[0053] The present invention provides a foldable track that is convenient to deploy and has a low cost.

[0054] The foldable track includes at least two groups of symmetrically arranged tracks. Each group of tracks includes at least a first track section (such as the left longitudinal rod 1) and a second track section (such as the left longitudinal rod 2). The first track section and the second track section are commonly connected to a cage (such as the left cage). Synchronous gears that mesh with each other are provided on the first track section and the second track section. The swinging directions of the first track section and the second track section are opposite, and the angles relative to the cage and the cross bar are equal. Auxiliary rods (such as the left auxiliary rod 1 and the left auxiliary rod 2) are provided to keep the angles of all cages consistent (parallel to the cages connected together). The auxiliary rods and the track sections are arranged axially staggered along the synchronous gears (not in the same plane so that they can be combined together when folding).

[0055] When unfolded, two symmetrical track segments rotate synchronously outward (opposite rotation directions, same rotation angles). Under the combined action of the auxiliary rod, the cage, and the synchronous gear, all track segments extend outward synchronously until all track segments are in a straight line. The process is reversed when folding up.

[0056] Track grooves (guide tracks) can be provided above the tracks for the solar panel assembly to move within the track grooves.

[0057] The synchronization structure between the first track segment (such as the left longitudinal rod 1) and the second track segment (such as the left longitudinal rod 2) is preferably a gear type, or it can also be other structures that can make the two ends of the track swing synchronously relative to the cage (opposite swing directions, same swing amplitudes).

[0058] The present invention aims to solve the contradiction between deployment and power generation capacity, and provides a container-type solar power generation device that is convenient for deployment and has low cost.

[0059] A container-type solar power generation device, characterized in that a folding track is provided at the bottom of the container, a folding solar panel mechanism is provided above the track, the solar panel mechanism moves on the track (after unfolding), one end of the track is fixed to the container, and there is at least one fixed point between the folding solar panel mechanism and the container.

[0060] When the track is folded up, each track segment is arranged parallel at the bottom of the container. When the solar panels are folded up, they are arranged nearly vertically inside the container and above the track.

[0061] The retraction and extension of the track can be driven by a power component provided on the container or by an external force.

[0062] The retraction and extension of the solar panels can be driven by a power component provided on the container or by an external force. BRIEF DESCRIPTION OF THE DRAWINGS
