Description

Technical Field

[0001] This patent relates to a folding solar panel mechanism. Background Art

[0002] In the era of rapid development of new energy, solar power generation applications are becoming more and more common. However, the laying and construction of solar photovoltaic panels are complex, with a long cycle and high costs. Moreover, once installed, it is very difficult to move, and its application is subject to certain limitations.

[0003] Although there are also containerized integrated structures, which improve the convenience of use, the deployment of the system requires the cooperation of manual labor and machinery, and the deployment is not convenient. There are also automated deployments, but due to structural constraints, the power generation capacity is small. Summary of the Invention

Each photovoltaic panel unit includes two cross arms, namely cross arm one and cross arm two, a connecting rod, a photovoltaic panel or a photovoltaic panel frame for fixing the photovoltaic panel; the middle parts of the two cross arms are hinged, and the hinge point divides the two cross arms into an upper part above the hinge point, a lower part below the hinge point, a front part in front of the hinge point, and a rear part behind the hinge point; the upper end of the connecting rod is hinged to the middle part of the photovoltaic panel or the photovoltaic panel frame;

[0007] The lower end of the connecting rod is hinged to the lower rear part of cross arm one, and one end of the photovoltaic panel or the photovoltaic panel frame close to the upper rear part of cross arm two is directly or indirectly hinged to the upper rear part of cross arm two; or, the lower end of the connecting rod is hinged to the lower front part of cross arm two, and one end of the photovoltaic panel or the photovoltaic panel frame close to the upper front part of cross arm one is directly or hinged to the upper front part of cross arm one through a fixed rod;

[0008] When the two cross arms rotate relative to the hinge point, the angle between the lower rear part of cross arm one and the upper rear part of cross arm two decreases from large to small within the interval, and the photovoltaic panel or the photovoltaic panel frame rotates around the middle part, gradually changing from the vertical state to the horizontal state or the inclined state.

[0009] For the above-mentioned foldable solar panel mechanism, the lower end of the connecting rod is hinged to the lower rear part of the first cross arm, and one end of the photovoltaic panel or the photovoltaic panel frame close to the upper rear part of the second cross arm is directly or indirectly hinged to the upper rear part of the second cross arm; when the two cross arms rotate relative to the hinge point, 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°), and the photovoltaic panel or the photovoltaic panel frame flips around the middle, gradually changing from the vertical state through the inclined state with the front lower and the rear higher, and then through the horizontal state to the inclined state with the front higher and the rear lower.

[0010] For the above-mentioned foldable solar panel mechanism, there are two first cross arms, two second cross arms and two connecting rods in each photovoltaic panel unit, which are arranged symmetrically on the left and right; the upper ends of the two connecting rods are respectively hinged to both sides of the middle part of the photovoltaic panel or the photovoltaic panel frame; one end on both sides of the photovoltaic panel or the photovoltaic panel frame close to the upper rear part of the second cross arm is directly or indirectly hinged to the upper rear parts of the two second cross arms respectively.

[0011] For the above-mentioned foldable solar panel mechanism, the rear end of the photovoltaic panel frame close to the second cross arm is fixedly connected to the front end of a fixed rod, and the rear end of the fixed rod is hinged to the rear end of the second cross arm.

[0012] For the above-mentioned foldable solar panel mechanism, the lower end of the connecting rod is hinged to the lower front part of the second cross arm, and one end of the photovoltaic panel or the photovoltaic panel frame close to the upper front part of the first cross arm is directly or hinged to the upper front part of the first cross arm through a fixed rod; when the two cross arms rotate relative to the hinge point, 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°), and the photovoltaic panel or the photovoltaic panel frame flips around the middle, gradually changing from the vertical state through the inclined state with the front higher and the rear lower, and then through the horizontal state to the inclined state with the front lower and the rear higher.

[0013] For the above-mentioned foldable solar panel mechanism, there are two first cross arms, two second cross arms and two connecting rods in each photovoltaic panel unit, which are arranged symmetrically on the left and right; the upper ends of the two connecting rods are respectively hinged to both sides of the middle part of the photovoltaic panel or the photovoltaic panel frame; one end on both sides of the front end of the photovoltaic panel or the photovoltaic panel frame close to the upper front part of the first cross arm is directly or indirectly hinged to the upper front parts of the two first cross arms respectively.

[0014] For the above-mentioned foldable solar panel mechanism, the front end of the photovoltaic panel or the photovoltaic panel frame close to the first cross arm is fixedly connected to the rear end of a fixed rod, and the front end of the fixed rod is hinged to the front end of the first cross arm.

[0015] For the above-mentioned foldable solar panel mechanism, when there are multiple photovoltaic panel units, the rear end of the first cross arm and the rear end of the second cross arm in the previous photovoltaic panel unit are respectively hinged to the front end of the second cross arm and the front end of the first cross arm in the next photovoltaic panel unit.

[0016] The above-mentioned foldable solar panel mechanism further includes a track. Only the lower end of one cross arm is fixed to the track, and the lower ends of the other cross arms are slidably arranged on the track.

[0017] The above-mentioned foldable solar panel mechanism further includes a container, which has a chassis, side frames fixed on the left and right sides of the chassis, and a top frame fixed on the side frames; the lower end of one cross arm is hinged to the side frame of the container; it further includes a solar panel folding drive device for driving the cross arm hinged to the side frame to swing around the hinge point with the side frame. The solar panel folding drive device includes a sector gear, a driving gear meshing with the sector gear, and a solar panel folding transmission mechanism for driving the driving gear to rotate; the sector gear is fixed on the cross arm hinged to the side frame, and the center line of the sector gear coincides with the center line of the hinge of the cross arm and the side frame; the driving gear is rotatably arranged on the side frame.

[0018] The beneficial effects of this patent are as follows:

[0019] In the foldable solar panel mechanism of this patent, cross arm one and cross arm two rotate relative to each other around their middle hinge points. The angle between the lower rear part of cross arm one and the upper rear part of cross arm two decreases from large to small within the range of (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 (deployed 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, thereby adjusting 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.

[0020] In each photovoltaic panel unit, there are two cross arm ones, cross arm twos, and connecting rods arranged symmetrically on the left and right. 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, cross arm one or cross arm two respectively, and the folding or unfolding is more flexible.

[0021] 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. The photovoltaic panel will not be blocked, and the solar energy can be reused. Moreover, the photovoltaic panel will not cause uneven illumination due to blockage, ensuring the service life of the photovoltaic panel. Description of the Drawings

This hinge point (hinge shaft) divides the right first cross arm and the right second cross arm into an upper part above the hinge point, a lower part below the hinge point, a front part in front of the hinge point, and a rear part behind the hinge point.

[0069] The upper ends of the two connecting rods are respectively hinged to both sides of the middle part of the photovoltaic panel frame (the upper end of the left connecting rod is hinged to the left side of the middle part of the photovoltaic panel frame, and the upper end of the right connecting rod is hinged to the right side of the middle part of the photovoltaic panel frame).

[0074] Except for the lower ends of the immovable second left cross arm, the immovable second right cross arm, the immovable first left cross arm, and the immovable first right cross arm hinged to the side frames (including the left side frame and the right side frame), the lower ends of the other second left cross arms and the lower ends of the other first left cross arms are all hinged to the left guide wheels 55 (if the lower ends of the second left cross arm and the first left cross arm are hinged together, the hinged lower ends of the second left cross arm and the first left cross arm are jointly hinged to the same left guide wheel 55), and the lower ends of the other second right cross arms and the lower ends of the other first right cross arms are all hinged to the right guide wheels 65 (if the lower ends of the second right cross arm and the first right cross arm are hinged together, the hinged lower ends of the second right cross arm and the first right cross arm are jointly hinged to the same right guide wheel 65). The left guide wheels 55 and the right guide wheels 65 are left-right symmetric.

[0077] Embodiment 3:

[0078] The main difference between Embodiment 3 and Embodiment 2 lies in:

[0079] The lower ends of the two connecting rods are hinged to the front lower part of the second cross arm (i.e., the lower end of the left connecting rod 53 is hinged to the front lower part of the left second cross arm 52, and the lower end of the right connecting rod 63 is hinged to the front lower part of the right second cross arm 62). The front upper end of the photovoltaic panel frame near the first cross arm is hinged to the front upper part of the first cross arm through a fixing rod (the front upper end of the photovoltaic panel frame 71 near the front upper part of the left first cross arm 51 is fixedly connected to the rear end of the left fixing rod 54, the front end of the left fixing rod 54 is hinged to the front end of the left first cross arm 51, the front upper end of the photovoltaic panel frame 71 near the front upper part of the right first cross arm 61 is fixedly connected to the rear end of the right fixing rod 64, and the front end of the right fixing rod 64 is hinged to the front end of the right first cross arm 61);

[0080] When the two cross arms rotate relative to the hinge point (the left first cross arm and the left second cross arm rotate around the hinge point of the left first cross arm and the left second cross arm, and / or the symmetric right first cross arm and the right second cross arm rotate around the hinge point of the right first cross arm and the right second cross arm), the angle a between the rear lower part of the left first cross arm and the front upper part of the left second cross arm, and the angle a between the rear lower part of the right first cross arm and the front upper part of the right second cross arm decrease from large to small within the interval (0°, 180°), and the photovoltaic panel frame flips around the middle, gradually changing from the vertical (folded) state through the inclined (deployed) state with the rear lower and the front higher, and then changing to the inclined (deployed) state with the rear higher and the front lower through the horizontal state.

[0081] In this patent, the foldable track can be quickly deployed or folded. Since there is a synchronization mechanism between one end and the other end of the left longitudinal rod in the foldable track, and there is also a synchronization mechanism between one end and the other end of the right longitudinal rod, the left longitudinal rod 1 and the left longitudinal rod 2 can swing synchronously but in opposite directions, and the right longitudinal rod 1 and the right longitudinal rod 2 can swing synchronously but in opposite directions. Therefore, the left longitudinal rod 1 and the left longitudinal rod 2 can be quickly folded or deployed to form the left track, and the right longitudinal rod 1 and the right longitudinal rod 2 can be quickly folded or deployed to form the right track. When the foldable track is in the folded state, the left longitudinal rod 1, the left longitudinal rod 2, the right longitudinal rod 1, the right longitudinal rod 2, and the cross bar are all parallel to each other, with a small volume and can be quickly moved.

[0082] The synchronization mechanism adopts meshing synchronization gears, and the structure is simpler.

[0083] 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 morphological changes symmetrical on both sides, and the foldable track can be deployed or folded more quickly and efficiently.

[0084] 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 arranged staggeredly in the axial direction of the synchronization gear. When in the folded state, the left longitudinal rod 1 and the left longitudinal rod 2 can be adjacent, and the right longitudinal rod 1 and the right longitudinal rod 2 can be adjacent, reducing the size after folding.

[0085] Rollers capable of rolling on the ground are provided at the bottom of the cross bar, which can reduce the resistance when the foldable track is deployed or folded.

[0086] The deployment or folding of the foldable track, and the folding or unfolding of the photovoltaic panel or the photovoltaic panel rack can all be directly operated manually without external force. In order to improve the operation efficiency and save labor, a track folding drive device and a battery panel folding drive device are installed.

[0087] The track folding drive device adopts a second drive shaft. The two ends of the second drive shaft are respectively connected to the two driven synchronization 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.

[0088] The battery panel folding drive device adopts two sector gears, a first drive shaft rotatably arranged on the top frame and extending to both 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 battery panel folding drive device from interfering with the folding or unfolding of the photovoltaic panel or the photovoltaic panel rack.

[0089] When the photovoltaic panel or the photovoltaic panel rack is in the vertical state and the track unit is in the folded state, the foldable solar panel mechanism and the foldable track are both located within the space enclosed by the bottom frame, side frame, and top frame of the container, facilitating the transportation and movement of the entire container-type solar power generation device.

[0090] 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 of the track unit between the folded state and the unfolded state 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.

[0091] The present invention provides a foldable solar panel mechanism photovoltaic panel frame that is convenient to deploy and has a low cost.

[0092] 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.

[0093] 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.

[0094] 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 under the drive of 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.

[0095] 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 lack of blockage ensures the service life of the photovoltaic panels.

[0096] The present invention provides a foldable track that is convenient to deploy and has a low cost.

[0097] The foldable track includes at least two groups of symmetrically arranged tracks. Each group of tracks includes at least a first track segment (such as the first left vertical rod) and a second track segment (such as the second left vertical rod). The first track segment and the second track segment are commonly connected to a cage (such as the left cage). Synchronous gears that mesh with each other are provided on the first track segment and the second track segment. The swinging directions of the first track segment and the second track segment are opposite, and the angles relative to the cage and the cross bar are equal. Auxiliary rods (such as the first left auxiliary rod and the second left auxiliary rod) are provided to keep the angles of all cages consistent (parallel to the cages connected together). The auxiliary rods and the track segments are arranged axially staggered along the synchronous gears (not in the same plane so that they can be combined together when folding).

[0098] When unfolded, two symmetrical track segments rotate outward synchronously (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 form a straight line. The process is reversed when folding up.

[0099] Track grooves (guide tracks) can be provided above the tracks for the solar panel assembly to move within the track grooves.

[0100] The preferred synchronous 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 a gear type, or other structures that can make the two ends of the track swing synchronously relative to the cage (opposite swing directions, same swing amplitudes).

[0101] The present invention aims to solve the contradiction between deployment and power generation capacity, and provides a containerized solar power generation device that is convenient for deployment and has a low cost.

[0102] A containerized solar power generation device, characterized in that folding tracks are provided at the bottom of the container, a folding solar panel mechanism is provided above the tracks, the solar panel mechanism moves on the tracks (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.

[0103] When the tracks are 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 are located above the tracks.

[0104] The retraction and extension of the tracks can be driven by power components provided on the container, or can be driven by external forces.

[0105] The retraction and extension of the solar panels can be driven by power components provided on the container, or can be driven by external forces.

[0106] The protection scope of this patent includes but is not limited to the above embodiments. The protection scope of this patent is subject to the claims, and any substitutions, deformations, and improvements that are easily conceivable by those skilled in the art to this technology fall within the protection scope of this patent.
