Description

Technical Field

[0001] This patent relates to a foldable track for installing solar panels. Background Art

[0002] In the era of rapid development of new energy, the application of solar power generation is becoming more and more common. However, the laying and construction of solar photovoltaic panels are complex, time-consuming, and costly. Moreover, once installed, it is very difficult to move, and its application is subject to certain limitations.

[0003] Although there is also an integrated container structure, the convenience of use has been improved. However, the deployment of the system requires the cooperation of manual labor and machinery, which is not convenient. There are also automated deployments, but due to structural constraints, the power generation capacity is small.

[0004] To install solar panels, it is necessary to install a foundation on the ground and then install the solar panels or the brackets of the solar panels on the foundation. However, the installation operation time of the foundation is relatively long, and generally it cannot be demolished or moved after installation. Summary of the Invention

[0005] The purpose of this patent is to provide a foldable track for installing solar panels, which is simple and convenient to install, can be quickly and efficiently deployed to form parallel tracks to form a foundation for installing solar panels, facilitating the movement of solar panels or the brackets of solar panels thereon, and can be quickly folded to reduce the volume and is convenient for movement.

A synchronization mechanism is provided between the rear end of the left first longitudinal bar and the front end of the left second longitudinal bar to enable the left first longitudinal bar and the left second longitudinal bar to swing synchronously but in opposite directions. The rear end of the left second longitudinal bar is hinged to the left end of the cross bar;

[0010] The left first longitudinal bar, the left retainer, the left second longitudinal bar, and the synchronization mechanism provided between the left first longitudinal bar and the left second longitudinal bar are respectively symmetrical to the right first longitudinal bar, the right retainer, the right second longitudinal bar, and the synchronization mechanism provided between the right first longitudinal bar and the right second longitudinal bar;

[0011] Drive the left and right symmetric left longitudinal rod 1 and right longitudinal rod 1 or left longitudinal rod 2 and right longitudinal rod 2 to swing synchronously but in opposite directions, and the track unit changes between the folded state and the unfolded state; 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; in the unfolded state, the left longitudinal rod 1 and the left longitudinal rod 2 are on the same straight line to form the left track, and the right longitudinal rod 1 and the right longitudinal rod 2 are on the same straight line to form the right track.

[0012] For the above-mentioned folding track, two meshing synchronous gears serving as the synchronous mechanism are respectively fixed to the rear end of the left longitudinal rod 1 and the front end of the left longitudinal rod 2, and two meshing synchronous gears serving as the synchronous mechanism are respectively fixed to the rear end of the right longitudinal rod 1 and the front end of the right longitudinal rod 2.

[0013] For the above-mentioned folding track, when the folding track includes a plurality of track units connected in sequence front and back, the front ends of the left longitudinal rod 1 and the right longitudinal rod 1 in the latter track unit are respectively hinged to the left end and the right end of the cross bar in the previous track unit, and a synchronous mechanism is provided between the front end of the left longitudinal rod 1 in the latter track unit and the rear end of the left longitudinal rod 2 in the previous track unit, and a synchronous mechanism is provided between the front end of the right longitudinal rod 1 in the latter track unit and the rear end of the right longitudinal rod 2 in the previous track unit.

[0014] For the above-mentioned folding track, each track unit further includes a left auxiliary rod 1, a left auxiliary rod 2, a right auxiliary rod 1, and a right auxiliary rod 2; the rear end of the left auxiliary rod 1 is hinged to the left holder, and the front and rear ends of the left auxiliary rod 2 are respectively hinged to the left holder and the cross bar; the rear end of the right auxiliary rod 1 is hinged to the right holder, and the front and rear ends of the right auxiliary rod 2 are respectively hinged to the right holder and the cross bar; the left auxiliary rod 1 and the left auxiliary rod 2 are symmetric with the right auxiliary rod 1 and the right auxiliary rod 2 respectively; the left auxiliary rod 1 is parallel to and has the same length as the left longitudinal rod 1, the left auxiliary rod 2 is parallel to and has the same length as the left longitudinal rod 2, the right auxiliary rod 1 is parallel to and has the same length as the right longitudinal rod 1, and the right auxiliary rod 2 is parallel to and has the same length as the right longitudinal rod 2.

[0015] For the above-mentioned folding track, when the folding track includes a plurality of track units connected in sequence front and back, the front ends of the left auxiliary rod 1 and the right auxiliary rod 1 in the latter track unit are respectively hinged to the left part and the right part of the cross bar in the previous track unit.

[0016] For the above-mentioned folding track, the synchronous mechanism is two meshing synchronous gears, and 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 arranged staggeredly in the axial direction of the synchronous gears.

[0017] For the above-mentioned folding track, rollers capable of rolling on the ground are provided at the bottom of the cross bar.

[0018] The above-mentioned folding track further includes a chassis. A left longitudinal rod one and a right longitudinal rod one that are symmetric left and right are hinged to the chassis, or a left longitudinal rod two and a right longitudinal rod two that are symmetric left and right are hinged to the chassis.

[0019] The beneficial effects of this patent are as follows:

Since there is a synchronization mechanism between the end parts of the left longitudinal rod one and the left longitudinal rod two in the folding track, and there is a synchronization mechanism between the end parts of the right longitudinal rod one and the right longitudinal rod two, 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 folding 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, with a small volume and can be quickly moved.

[0021] The synchronization mechanism adopts meshing synchronization gears, and the structure is simpler.

[0022] Each track unit further includes a left auxiliary rod one, a left auxiliary rod two, a right auxiliary rod one, and a right auxiliary rod two, which can make the morphological changes symmetric left and right, and the folding track can be unfolded or folded more quickly and efficiently.

[0023] The left auxiliary rod one and the left longitudinal rod one, the left auxiliary rod two and the left longitudinal rod two, the right auxiliary rod one and the right longitudinal rod one, and the right auxiliary rod two and the right longitudinal rod two are arranged staggeredly in the axial direction of the synchronization gear. When in the folded state, the left longitudinal rod one and the left longitudinal rod two can be adjacent, and the right longitudinal rod one and the right longitudinal rod two can be adjacent, reducing the size after folding.

[0024] Rollers that can roll on the ground are arranged at the bottom of the cross bar, which can reduce the resistance when the folding track is unfolded or folded.

[0025] This folding track can be quickly and efficiently unfolded to form parallel tracks, forming the basis for installing solar panels, facilitating the movement of solar panels or the brackets of solar panels on it, and can be quickly folded to reduce the volume and is convenient for movement.

[0063] One crossbar in the folding track is fixed to the underframe of the container; to distinguish it from other crossbars 30, the crossbar fixed to the underframe is called the fixed crossbar 301, and the fixed crossbar 301 can obviously be a part of the underframe. Except for the fixed crossbar 301, the structures at both ends of other crossbars are similar to those of the left cage and the right cage.

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.

[0073] 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), and the lower ends of the two connecting rods are hinged to the rear lower part of the first cross arm (the lower end of the left connecting rod is hinged to the rear lower part of the left first cross arm, and the lower end of the right connecting rod is hinged to the rear lower part of the right first cross arm).

[0074] The rear end of the rear lower part of the left first cross arm and the rear end of the rear upper part of the left second cross arm in the previous photovoltaic panel unit are respectively hinged to the front end of the front lower part of the left second cross arm and the front end of the front upper part of the left first cross arm in the next photovoltaic panel unit; the rear end of the rear lower part of the right first cross arm and the rear end of the rear upper part of the right second cross arm in the previous photovoltaic panel unit are respectively hinged to the front end of the front lower part of the right second cross arm and the front end of the front upper part of the right first cross arm in the next photovoltaic panel unit.

[0077] The lower end of a second left cross arm and the lower end of a first left cross arm are jointly hinged to the left side frame of the container, and the lower end of a second right cross arm and the lower end of a first right cross arm are jointly hinged to the right side frame of the container. To distinguish them from other cross arms, the first left cross arm, the second left cross arm, the first right cross arm, and the second right cross arm hinged to the side frames (including the left side frame and the right side frame) are called the immovable first left cross arm 511, the immovable second left cross arm 521, the immovable first right cross arm 611, and the immovable second right cross arm 621.

[0078] 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, 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, 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 symmetric left and right.

[0079] The solar panel folding drive device 8 for driving the immovable second left cross arm 521 and the immovable second right cross arm 621 hinged to the side frames to swing around the hinge points with the side frames includes symmetric left and right sector gears, namely the left sector gear 81 and the right sector gear 85, and a solar panel folding transmission mechanism for driving the two sector gears to swing synchronously; the left sector gear is fixed on the immovable second left cross arm 521 hinged to the side frame, and the center line of the left sector gear coincides with the center line of the hinge of the second left cross arm and the side frame; the right sector gear is fixed on the immovable second right cross arm 621 hinged to the side frame, and the center line of the right sector gear coincides with the center line of the hinge of the second right cross arm and the side frame.

Each driven sprocket is coaxially and fixedly connected to a driving gear 87. The two driving gears are respectively meshed with a left sector gear 81 and a right sector gear 85. Of course, the battery panel folding transmission mechanism 8 further includes a power transmission mechanism 86 which belongs to the prior art and drives the first driving shaft 40 to rotate.

[0081] Embodiment 3:

[0082] The main difference between Embodiment 3 and Embodiment 2 lies in that:

[0083] The lower ends of the two connecting rods are hinged to the front lower part of the second cross arm (that is, 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 end of the front upper part of the photovoltaic panel frame close to the first cross arm is hinged to the front upper part of the first cross arm (the front end of the front upper part of the photovoltaic panel frame 71 close to 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 end of the front upper part of the photovoltaic panel frame 71 close to 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);

[0084] 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 included 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 included 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.

[0085] In this patent, for the folding solar panel mechanism, the first cross arm and the second cross arm rotate relative to each other around 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 range of (0°, 180°), and the photovoltaic panel or the photovoltaic panel frame can change from the vertical (folded) state to the horizontal state or the inclined state (deployed state). When in the vertical (folded) state, the distance between the photovoltaic panels or the photovoltaic panel frames is very small, and the overall size is small, which is convenient for movement, loading and unloading. When in the horizontal state or the inclined state, the photovoltaic panels are in the working state. By changing the angle between the two cross arms, the angle of the photovoltaic panel or the photovoltaic panel frame 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.

[0086] There are two first cross arms, two second cross arms and two connecting rods arranged symmetrically on the left and right in each photovoltaic panel unit, and the structure is more stable and reliable. The two sides of the photovoltaic panel or the photovoltaic panel frame 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.

[0087] The photovoltaic panel or the photovoltaic panel frame is located above the two left and right cross arms or between the two 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.

[0088] The unfolding or folding of the folding track and the folding or unfolding of the photovoltaic panel or the photovoltaic panel frame 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.

[0089] The track folding drive device uses the second driving shaft. The two ends of the second driving shaft are respectively connected to the two driven synchronous gears through gear transmission devices, with a simple structure and ensuring the synchronous folding and unfolding of the left track and the right track.

[0090] The panel folding drive device uses 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 frame.

[0091] When the photovoltaic panel or the photovoltaic panel frame 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.

[0092] 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, 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.

[0093] The present invention provides a foldable solar panel mechanism photovoltaic panel frame that is convenient to deploy and has a low cost.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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, and no blockage ensures the service life of the photovoltaic panels.

[0098] The present invention provides a foldable track that is convenient to deploy and has a low cost.

[0099] 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 all the cages at the same angle (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).

[0100] When it is unfolded, two symmetric track segments rotate synchronously outward (opposite rotation directions and the same rotation angle). Under the combined action of the auxiliary rod, the cage, and the synchronous gear, all the track segments extend outward synchronously until all the track segments form a straight line. The process is reversed when it is folded up.

[0101] A track groove (guide track) can be provided above the track for the solar panel assembly to move within the track groove.

[0102] The 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 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 and the same swing amplitude).

[0103] 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 a low cost.

[0104] 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 it is unfolded), 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.

[0105] When the track is folded up, each track segment is arranged parallel at the bottom of the container. When the solar panel is folded up, it is arranged nearly vertically inside the container and is located above the track.

[0106] The retraction and extension of the track can be driven by a power component provided on the container or by an external force.

[0107] The retraction and extension of the solar panel can be driven by a power component provided on the container or by an external force.

[0108] The protection scope of this patent includes but is not limited to the above - mentioned embodiments. The protection scope of this patent is subject to the claims, and any replacement, deformation, or improvement that is easily conceivable by those skilled in the art for this technology falls within the protection scope of this patent.
