[0002] In an era of rapid development of new energy, solar power generation is becoming more and more common. However, the installation of solar photovoltaic panels is complicated, time-consuming, and costly. Once installed, they are difficult to move, so their application is subject to certain restrictions.

[0024] In the above container-type solar power generation device, rollers capable of rolling on the ground are arranged at the bottom of the crossbar.

[0025] In the above-mentioned container-type solar power generation device, each photovoltaic panel unit has two cross arms 1, 2 and connecting rods, which are arranged symmetrically on the left and right; the upper ends of the two connecting rods are respectively hinged to the two sides of the middle part of the photovoltaic panel or the photovoltaic panel frame; the two sides of one end of the photovoltaic panel or the photovoltaic panel frame close to the rear upper part of the cross arm 2 are directly or indirectly hinged to the rear upper parts of the two cross arms 2.

[0026] In the above-mentioned container-type solar power generation device, each photovoltaic panel unit has two cross arms 1, 2 and connecting rods, namely left cross arm 1, right cross arm 1, left cross arm 2, right cross arm 2, left connecting rod and right connecting rod, which are arranged symmetrically on the left and right sides; the upper ends of the left connecting rod and the right connecting rod are respectively hinged to the two sides of the middle part of the photovoltaic panel or the photovoltaic panel frame; the two sides of one end of the photovoltaic panel or the photovoltaic panel frame close to the rear upper part of the cross arm 2 are directly or indirectly hinged to the rear upper part of the left cross arm 2 and the right cross arm 2 respectively; in the unfolded state of the folding track, the photovoltaic panel or the photovoltaic panel frame is directly or indirectly hinged to the rear upper part of the left cross arm 2 and the right cross arm 2. When the angle between the rear lower part of the left cross arm one and the rear upper part of the left cross arm two or the angle between the rear lower part of the right cross arm one and the rear upper part of the right cross arm two changes within the interval (0°, 180°), except for the lower ends of the left cross arm two and the right cross arm two or the lower ends of the left cross arm one and the right cross arm one symmetrically hinged on the side frame, the other lower ends of the left cross arm two and the other lower ends of the left cross arm one slide on the left track, and the other lower ends of the right cross arm two and the other lower ends of the right cross arm one slide on the right track.

[0027] The above-mentioned container-type solar power generation device also includes a solar panel folding drive device for driving the left cross arm 2 and the right cross arm 2 hinged on the side frame, or driving the left cross arm 1 and the right cross arm 1 hinged on the side frame to swing around the hinge point with the side frame.

[0028] In the above-mentioned container-type solar power generation device, the panel folding drive device includes left-right symmetrical fan gears, namely a left fan gear and a right fan gear, and a panel folding transmission mechanism that drives the two fan gears to swing synchronously respectively; the panel folding transmission mechanism is arranged on the side frame, including two driving gears that are respectively meshed with the two fan gears; the left fan gear is fixed to the left cross arm 2 or the left cross arm 1 hinged on the side frame, and the center line of the left fan gear coincides with the center line of the left cross arm 2 or the left cross arm 1 hinged to the side frame; the right fan gear is fixed to the right cross arm 2 or the right cross arm 1 hinged on the side frame, and the center line of the right fan gear coincides with the center line of the right cross arm 2 or the right cross arm 1 hinged to the side frame.

[0029] The above-mentioned container-type solar power generation device, the solar panel folding transmission mechanism includes a driving shaft one that is arranged on a rotatable top frame and extends to the left and right sides. Both ends of the driving shaft one are fixed with driving sprockets, and each driven sprocket is respectively rotatably arranged on a driven sprocket shaft through a chain drive with each driving sprocket. The driven sprocket shaft is fixed on the side frame, and each driven sprocket is coaxially fixedly connected to a driving gear.

[0030] The above container-type solar power generation device also includes a track folding drive device for driving two left-right symmetrical synchronous gears 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] A roller capable of rolling on the ground is arranged at the bottom of the crossbar, so that resistance can be reduced when the foldable track is unfolded or folded.

[0040] The foldable solar panel mechanism, cross arm one and cross arm two rotate relative to each other around their middle hinge points, the angle between the rear lower part of cross arm one and the rear upper part of cross arm two changes from large to small within the interval (0°, 180°), and the photovoltaic panel or photovoltaic panel frame can change from a vertical (folded) state to a horizontal state or an inclined state (unfolded state); in the vertical (folded) state, the distance between the photovoltaic panels or photovoltaic panel frames is very small, the overall size is small, and it is convenient to move, load and unload. In the horizontal state or inclined state, the photovoltaic panel is in a working state. By changing the angle between the two cross arms, the angle of the photovoltaic panel or photovoltaic panel frame can be changed, thereby adjusting the angle between the photovoltaic panel and the sunlight, so that the photovoltaic panel is always at the angle with the highest power generation efficiency.

[0041] There are two cross arms 1, 2 and connecting rods in each photovoltaic panel unit that are symmetrically arranged on the left and right, and the structure is more stable and reliable. The two sides of the photovoltaic panel or photovoltaic panel frame are directly or indirectly connected to the connecting rod, cross arm 1 or cross arm 2, respectively, and folding or unfolding is more flexible and free.

[0042] The photovoltaic panel or photovoltaic panel frame is located above the left and right cross arms or between the left and right cross arms. The photovoltaic panel will not be blocked, and the solar energy can be reused. The photovoltaic panel will not cause uneven lighting due to blocking, thereby ensuring the life of the photovoltaic panel.

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

[0044] The track folding driving 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. The structure is simple and ensures the synchronous folding and unfolding of the left track and the right track.

[0045] The solar panel folding drive device adopts two fan-shaped gears, a driving shaft extending to the left and right sides on the rotational arrangement of the top frame, a driven sprocket shaft fixed on the side frame, etc., which fully utilizes the space of the container and prevents the solar panel folding drive device from hindering the folding or unfolding of the photovoltaic panel or photovoltaic panel frame.

[0046] When the photovoltaic panel or photovoltaic panel frame is in a vertical state and the track unit is in a folded state, the foldable solar panel mechanism and the foldable track are both located in the space surrounded by the bottom frame, side frame and top frame of the container, making it convenient to transport and move 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 hindering the track unit from changing between the folded state and the unfolded state when the photovoltaic panel or photovoltaic panel rack is in a vertical state, no guide rail is provided on the left track or the right track that is opposite to the guide wheels in the foldable solar panel mechanism.

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

[0049] The foldable solar panel mechanism photovoltaic panel frame includes a cross arm one and a cross arm two, which are hinged in the middle and include a connecting rod hinged to the lower half of the cross arm one. 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 and can be set to slide on a track, or one end of one cross arm can be fixed and one end of the other cross arm can slide.

[0051] Changing the angle of the two cross arms can change the angle of the photovoltaic panel rack. When the photovoltaic panel needs to be used for power generation, the horizontal angle of the two cross arms is reduced. Driven by the connecting rod, the photovoltaic panel gradually flips up until it reaches the required angle. Changing the angle of the cross arms can also meet the angle between the photovoltaic panel and the sunlight. Increasing the angle of the cross arms can fold up the photovoltaic panel.

[0052] The present invention has a simple structure, and the angles of all photovoltaic panels can be changed simply by changing the angle of the cross arms. When unfolded, the photovoltaic panels are located above the cross arms or between the left and right cross arms. There are basically no parts blocking the photovoltaic panels, and solar energy can be reused. Blockage will cause uneven lighting, and no blocking ensures the life of the photovoltaic panels.

[0053] The invention provides a foldable track which is easy to deploy and low in cost.

[0054] The foldable track includes at least two groups of symmetrically arranged tracks, each group of tracks includes at least track segment 1 (such as left longitudinal rod 1) and track segment 2 (such as left longitudinal rod 2), track segment 1 and track segment 2 are connected to a retaining frame (such as left retaining frame), and mutually meshing synchronous gears are arranged on track segment 1 and track segment 2. The swinging directions of track segment 1 and track segment 2 are opposite, and the angles relative to the retaining frame and the cross bar are equal. Auxiliary rods (such as left auxiliary rod 1 and left auxiliary rod 2) are arranged so that all the retaining frame angles remain consistent (maintain parallel with the retaining frame). The auxiliary rods and the track segments are staggered along the axial direction of the synchronous gear (not in the same plane so that they can be put together when folded).

[0055] When unfolding, two symmetrical track segments rotate outward synchronously (rotation directions are opposite and rotation angles are the same), and under the joint action of the auxiliary rod, the retaining frame and the synchronous gear, all the track segments extend outward synchronously until all the track segments are connected in a straight line. The opposite is true when folding.

[0056] A track groove (guide track) can be arranged above the track for the solar panel assembly to move in the track groove.

[0057] The synchronization structure between the track segment 1 (such as the left longitudinal rod 1) and the track segment 2 (such as the left longitudinal rod 2) is preferably a gear type, but it can also be other structures that enable the two end tracks to swing synchronously relative to the retaining frame (swinging directions are opposite and the same swing amplitude).

[0058] The present invention aims to solve the contradiction between deployment and power generation capacity, and to provide a container-type solar power generation device which is easy to deploy and low in cost.

[0059] A container-type solar power generation device is characterized in that a folding track is arranged at the bottom of the container, a folding solar panel mechanism is arranged 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 fixation between the folding solar panel mechanism and the container.

[0060] When the track is folded and stowed, the sections of the track are arranged in parallel at the bottom of the container. When the solar panels are stowed, they are arranged nearly vertically in the container, located above the track.

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

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

[0100] One of the crossbars in the foldable rail is fixed to the bottom frame of the container; in order to distinguish it from the other crossbars 30, the crossbar fixed to the bottom frame is called a fixed crossbar 301, and the fixed crossbar 301 can obviously be a part of the bottom frame. Except for the fixed crossbar 301, the structures at both ends of the other crossbars are similar to the structures of the left and right retainers. From this perspective, the other crossbars can be regarded as the left and right retainers fixed at the left ends of an ordinary straight crossbar (see Fig.31 ).

[0104] When the track unit is in the unfolded state and the photovoltaic panel rack is in the vertical (folded) state, no guide track is set on the left track (including the left longitudinal rod 1 and the left longitudinal rod 2) which is opposite to the left guide wheel in the folding solar panel mechanism, and no guide track is set on the right track (including the right longitudinal rod 1 and the right longitudinal rod 2) which is opposite to the right guide wheel in the folding solar panel mechanism.
