Description

Technical Field

[0001] This invention belongs to the field of mobile photovoltaic devices, specifically a foldable mobile photovoltaic device that can be quickly and automatically set up. Background Technology

[0002] Solar photovoltaic (PV) systems, also known as photovoltaic systems, are facilities that convert solar energy into direct current (DC) electricity using the photovoltaic effect of photovoltaic semiconductor materials. In recent years, due to the increased construction and investment in my country's power, telecommunications, mobile, and network infrastructure, traditional PV power stations are generally built outdoors and installed on the ground using brackets. Building PV power stations on the ground requires ground preparation, bracket erection, etc., resulting in long construction cycles and heavy workloads. Moreover, the division of labor among ground preparation, bracket installation, and PV panel installation is quite specialized, leading to many problems in the professional coordination during on-site construction. This has led to a demand for foldable PV systems that are easy to install and erect, used to support agricultural and water resource management programs, provide auxiliary power for construction sites, emergency areas, and off-grid charging stations, and can also serve as additional power sources to support existing generators or supply power to remote areas. Their ability to operate in both grid-connected and off-grid environments further expands their utility, meeting the needs of activities, venues, and communities that require reliable and sustainable power solutions.

[0003] Most existing solutions involve hinged and folded photovoltaic panels to form a structure the same size as a standard shipping container. The folded photovoltaic panels are then transported by a vehicle to the designated installation location, where they are finally slid out and erected. Before erection, personnel usually need to lay tracks in advance to reduce obstacles such as stones and weeds on the ground that may affect the unfolding of the photovoltaic panels, making the process of sliding out the photovoltaic panels smoother and facilitating the traction and erection of the photovoltaic panels.

[0004] Furthermore, during the installation of photovoltaic panels, it is necessary to ensure that each photovoltaic panel is installed sequentially and one by one. This allows operators to control and correct the installation process, preventing interference and jamming when photovoltaic panels are installed simultaneously, or multiple faults that are difficult to resolve at the same time. The locking structure used in existing products on the market usually employs a manual locking and unlocking method. In this method, workers need to manually unlock the panels one by one during the installation process to ensure that the photovoltaic panels are installed in sequence and to ensure the stability of the installation process. However, this method has a low degree of automation, wastes manpower, and affects the installation speed of photovoltaic panels.

[0005] Chinese Patent Publication No. CN219780087U discloses a mobile foldable solar photovoltaic power generation device, including a base plate, a front side plate, a rear side plate, and a top plate. A first mounting bracket is provided on the base plate, and a first telescopic frame and a second telescopic frame are arranged perpendicularly to the first mounting bracket and are located at both ends of the first mounting bracket. Slide grooves are provided on the first and second telescopic frames. A telescopic frame is provided on the first mounting bracket, and the telescopic frame includes a solar panel mounting frame for mounting solar panels, a first connecting plate, and a second connecting plate. A first fixing member is provided on one side of the solar panel mounting frame, and a second fixing member is provided on the other side of the solar panel mounting frame. Adjacent solar panel mounting frames are connected by the first connecting plate and the second connecting plate. A support member connected to a slider is provided on the first connecting plate. The slider is located in the slide groove and can move along the slide groove. It is transported by a box and its foldable structure enables rapid on-site installation, saving installation time and achieving the purpose of rapid commissioning.

[0006] However, the aforementioned patents still have the following drawbacks:

[0007] 1. The above-mentioned patent adopts the traditional method of pre-laying tracks and then pulling them out. This method is not convenient for rapid erection and requires 3-4 workers to carry out the erection work at the same time, which wastes a lot of time and manpower.

[0008] 2. In the above-mentioned patent, there is no locking mechanism between the photovoltaic panels. Therefore, during the process of unfolding and setting up the photovoltaic panels, the unfolded photovoltaic panels cannot be locked together, which leads to unstable factors such as shaking when the photovoltaic panels are stretched and unfolded, making it difficult to ensure the stability of the unfolding and setting up process.

[0009] 3. The above patent does not describe a structure for controlling the unfolding of photovoltaic panels one by one, which can easily lead to a chaotic and disorderly unfolding process. During the unfolding process, photovoltaic panels may interfere with each other and get stuck, or multiple faults may occur simultaneously and be difficult to eliminate, affecting the stability of the unfolding and installation process. Summary of the Invention

[0010] To overcome the shortcomings of existing technologies, this invention addresses the technical problem by setting up a flexible track and a first motor. During the installation of the frame and photovoltaic panels, the flexible track is simultaneously laid behind the motor's moving direction while the first motor rotates and pulls, achieving automatic track laying. This eliminates the need for pre-laying the track manually, significantly saving manpower and time, increasing the efficiency of photovoltaic panel installation, and further improving automation and economy. By setting locking plates and arc-shaped locking plates, the arc-shaped locking plates restrict the corresponding second hinges to their position before the frame is fully unfolded. Only after the front frame is fully unfolded and the arc-shaped locking plates are completely disengaged from the arc-shaped grooves can the corresponding second hinges move. This allows the frame and photovoltaic panels to unfold sequentially, ensuring stability during the unfolding and installation process. Furthermore, by setting locking holes and locking pins, when the frame and photovoltaic panels are fully unfolded, the locking pins engage with the locking holes, and the locking plates lock and fix adjacent frames, ensuring the shape of the unfolded frame. This ensures that the frames remain stable during the traction and installation process, preventing swaying.

[0011] To achieve the above objectives, the present invention provides the following technical solution: a rapidly and automatically erected foldable mobile photovoltaic device, comprising:

[0012] The compartment contains multiple frames, each frame having a photovoltaic panel fixedly connected inside. The bottoms of adjacent frames are hinged together by a second hinge, and the tops of adjacent frames are hinged together by a third hinge.

[0013] The frame has multiple flexible tracks on both sides. The outermost second hinge edge is rotatably equipped with a drive wheel, and each drive wheel is connected to the corresponding flexible track. Each of the remaining second hinge edges is rotatably equipped with a driven wheel, and each driven wheel is rotatably connected to the corresponding flexible track.

[0014] The inner wall of the compartment is provided with multiple unwinding components. Each flexible track is fixed at both ends to the inside of the compartment and to the unwinding component. A locking component is provided between the bottoms of two adjacent frames.

[0015] Furthermore, the outermost second hinge has a first wheel frame fixedly connected to both ends of its bottom, and a first motor is fixedly connected to each first wheel frame. The power output end of each first motor passes through the first wheel frame and is connected to the corresponding driving wheel. The remaining second hinges have a second wheel frame fixedly connected to both ends of their bottom, and each driven wheel is rotatably connected to the corresponding second wheel frame.

[0016] Furthermore, each of the second wheel frames is fixedly connected to a limiter on both sides of the driven wheel, and each limiter is fitted and slidably connected to the flexible track. The outermost second hinge is hinged to the adjacent frame with a parallel connecting rod.

[0017] Furthermore, the unwinding component includes a winding wheel, and a set of winding wheels is rotatably arranged at each end of the inner side of the chamber corresponding to the position of each flexible track. Each set of winding wheels includes two winding wheels arranged vertically. Each flexible track is wound and stored between the two winding wheels arranged vertically. Guide wheels are rotatably connected at each end of the inner side of the chamber corresponding to the position of each flexible track, and the flexible track passes around the outside of the guide wheels.

[0018] Furthermore, the shaft of one of the winding reels in each group passes through the housing and is fixedly connected to a worm gear. A set of rod seats is fixedly connected to the outer wall of the housing at the corresponding position of each worm gear. A worm gear that meshes with the worm gear is rotatably connected inside each set of rod seats. A second motor is fixedly connected to one end of each set of rod seats, and the power output end of each second motor is connected to the corresponding worm gear.

[0019] Furthermore, the locking component includes locking plates, which are spaced apart at both ends of the bottom of the frame. The locking plates on both sides of the body are installed in opposite directions. Each locking plate has an arc-shaped groove. Arc-shaped locking pieces are fixed at the two ends of the body at the corresponding positions of each locking plate. The end of each arc-shaped locking piece can be slidably connected with the arc-shaped locking piece.

[0020] Furthermore, each of the locking pieces has a locking hole at its bottom end, and each frame without a locking piece is fixedly connected to a pin seat at both ends at its bottom. A locking pin is slidably connected in each pin seat, and a spring is provided between each locking pin and its corresponding pin seat. When the photovoltaic panel and the frame are unfolded, the end of the locking pin can be inserted into the corresponding locking hole and engaged.

[0021] Furthermore, the flexible track is made of rubber, and steel wires are embedded inside the flexible track. The surface of the flexible track in contact with the ground is rough.

[0022] Furthermore, the body includes a bottom plate, with end plates fixedly connected to both ends of the bottom plate, and a detachably connected top plate provided on the top of the two end plates.

[0023] Furthermore, a first hinge is fixedly connected to each side of the base plate, and a side plate is hinged to each first hinge. A latch is fixedly provided at the edge of each end plate, and each latch can lock and fix the edge of the side plate. Multiple support plates for supporting photovoltaic panels are fixedly connected to the inner side of the side plate.

[0024] In summary, compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] (1) By setting up a flexible track and a first motor, the flexible track can be laid behind the first motor in the direction of movement of the first motor while the frame and photovoltaic panels are being erected. This achieves automatic laying of the flexible track without the need for manual laying of the track in advance, which greatly saves manpower and time, making the photovoltaic panel erection more efficient and freeing up manpower, further improving the degree of automation and economy.

[0026] (2) By setting locking plates and arc-shaped locking plates, the arc-shaped locking plates restrict the corresponding second hinges to remain in place and cannot move when the frame is not fully unfolded. Only after the front frame is fully unfolded and the arc-shaped locking plates are completely disengaged from the arc-shaped groove can the corresponding second hinges move, thereby realizing the sequential unfolding of the frame and photovoltaic panels, ensuring the stability of the unfolding and erection process.

[0027] (3) By setting locking holes and locking pins, when the frame and photovoltaic panel are fully unfolded, the locking pins are used to engage with the locking holes, and the adjacent frames are locked and fixed by locking pieces to ensure the shape of the frame after unfolding, so that the frames remain stable during the traction erection process and avoid shaking.

Detailed Implementation

[0039] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0040] like Figure 1-10 As shown, a foldable mobile photovoltaic device that can be quickly and automatically erected includes a base plate 10. Multiple frames 16 are provided on the base plate 10. A photovoltaic panel 15 is fixedly connected in each frame 16. The tops of adjacent frames 16 are hinged by a third hinge 18, and the bottoms of adjacent frames 16 are hinged by a second hinge 17. The second hinge 17 located in the middle is fixedly connected to the base plate 10. The hinged frames 16 can be unfolded in an M-shape. End plates 11 are fixedly connected to both ends of the base plate 10, and top plates 12 are detachably provided on the top of the two end plates 11.

[0041] By setting up a hinged frame 16, the frame 16 and photovoltaic panels 15 can be folded and stored in the box composed of the bottom plate 10, end plate 11 and top plate 12 during transportation, which is convenient for transportation. Then, during the erection, the frame 16 and photovoltaic panels 15 can be unfolded in an M shape, so that the photovoltaic panels 15 can get sufficient sunlight space, thereby realizing photovoltaic power generation to support agricultural and water resource management plans and provide auxiliary power for construction sites, emergency areas and off-grid charging stations.

[0042] like Figure 1-10As shown, four sets of winding wheels 26 are rotatably arranged on the inner side of the end plate 11. Each set of winding wheels 26 includes two winding wheels 26 arranged vertically. Each set of winding wheels 26 is wound and housed with a flexible track 25. The end of the flexible track 25 away from the winding wheel 26 is fixedly connected to the base plate 10. Each flexible track 25 is set at both ends of the frame 16. The two outermost second hinges 17 are fixedly connected to the bottom ends of the first wheel frame 19. Each first wheel frame 19 is fixedly connected to one side of a first motor 20. The power output end of each first motor 20 passes through the first wheel frame 19 and is connected to the first motor 20 through transmission. Each first motor 20 is connected to the corresponding flexible track 25 through transmission.

[0043] By setting up the flexible track 25 and the first motor 20, during the process of unfolding and erecting the frame 16 and the photovoltaic panel 15, the flexible track 25 can be laid simultaneously behind the moving direction of the first motor 20 while the first motor 20 is rotating and pulling. This facilitates the subsequent movement of the frame 16 and the photovoltaic panel 15 and improves the smoothness of the erection process.

[0044] Furthermore, by using the first motor 20 to pull the laying and the winding wheel 26 to unwind simultaneously, the flexible track 25 can be laid automatically without the need for manual track laying in advance, which greatly saves manpower and time, making the installation efficiency of photovoltaic panels 15 higher and freeing up manual labor, further improving the degree of automation and economy.

[0045] like Figure 1-10 As shown, except for the second hinge 17 located in the middle and the outermost side, the bottom ends of the other second hinges 17 are respectively fixedly connected to second wheel frames 22. Each second wheel frame 22 is rotatably connected to a driven wheel 23 on one side. Each driven wheel 23 is rolledly connected to the corresponding flexible track 25. Each second wheel frame 22 is fixedly connected to limiters 24 on both sides of the driven wheel 23. Each limiter 24 is fitted and slidably connected to the corresponding flexible track 25. The outermost second hinge 17 is hinged to the adjacent frame 16 by a parallel connecting rod 38.

[0046] By setting the driven wheel 23, the flexible track 25 isolates the driven wheel 23 from the ground and provides a smooth movement trajectory, so that the frame 16 and the photovoltaic panel 15 can slide and unfold more smoothly on the surface of the flexible track 25. This avoids the ground stones or weeds from hindering the unfolding process of the frame 16 and the photovoltaic panel 15, thus eliminating the need for manual removal of debris in advance, improving the automation level of photovoltaic panel installation and the stability and smoothness of the unfolding process of the photovoltaic panel 15 and the frame 16.

[0047] By setting the limiter 24, the relative position between the driven wheel 23 and the flexible track 25 can be limited, effectively preventing the flexible track 25 from deforming and causing the driven wheel 23 to detach from the surface of the flexible track 25. It also provides additional support and improves the stability of the second hinge 17 supporting the frame 16 and the photovoltaic panel 15. By setting the parallel link 38, after the initial deployment, the parallel link 38 is tightened and fixed, so that the outermost second hinge 17 always remains horizontal, thereby ensuring that the driving wheel 21 maintains a stable posture for traction.

[0048] like Figure 1-10 As shown, the flexible track 25 is made of rubber and has steel wires embedded inside it. The flexible track 25 is used to make the surface in contact with the ground rough.

[0049] The flexible track 25 is made of rubber, which meets the requirements for its roll-up and storage. By embedding steel wires inside the flexible track 25, its resistance to tensile deformation is improved. This prevents the flexible track 25 from deforming due to elastic deformation caused by the first motor 20 pulling it during the process, which would make it difficult to stably guide the subsequent unfolding of the photovoltaic panel 15 and frame 16. In addition, the surface of the flexible track 25 in contact with the ground is roughened, which effectively increases the friction between the flexible track 25 and the ground, and improves the stability of the flexible track 25 in supporting and guiding the photovoltaic panel 15 and frame 16 after it is laid.

[0050] like Figure 1-10 As shown, the shaft of one of the winding wheels 26 in each group of winding wheels 26 passes through the box body and is fixedly connected to a worm gear 27. A set of rod seats 28 is fixedly connected to the outer wall of the box body at the corresponding position of each worm gear 27. A worm 29 that meshes with the worm gear 27 is rotatably connected inside each set of rod seats 28. A second motor 30 is fixedly connected to one end of each set of rod seats 28. The power output end of each second motor 30 is connected to the corresponding worm 29 for transmission.

[0051] By setting up a worm gear 27 and a worm 29, the function of driving the winding wheel 26 to rotate and unwind is realized, which in turn, in conjunction with the traction of the first motor 20, achieves the effect of automatically laying the flexible track 25.

[0052] like Figure 1-10As shown, each frame 16 with a gap of one has a locking piece 31 fixedly connected to both ends of its bottom. The locking pieces 31 on both sides of the base plate 10 are symmetrically arranged. Each locking piece 31 has an arc-shaped groove 32. An arc-shaped locking piece 33 is fixedly connected to the inner side of each end plate 11 at the corresponding position of each locking piece 31. Each arc-shaped locking piece 33 can slide and connect with the corresponding arc-shaped groove 32. When the frame 16 is fully unfolded, the arc-shaped locking piece 33 can just completely disengage from the arc-shaped groove 32. Each locking piece 31 has a locking hole 34 at its bottom end. Each frame 16 without a locking piece 31 has a pin seat 36 fixedly connected to both ends of its bottom. A locking pin 35 is slidably connected in each pin seat 36. A spring 37 is provided between each locking pin 35 and the corresponding pin seat 36. When the photovoltaic panel 15 and the frame 16 are unfolded, the end of the locking pin 35 can be inserted into the corresponding locking hole 34 and engaged.

[0053] By setting locking piece 31 and arc-shaped locking piece 33, the arc-shaped locking piece 33 restricts the corresponding second hinge 17 to remain stationary and cannot move when the frame 16 is not fully unfolded. Only after the front frame 16 is fully unfolded and the arc-shaped locking piece 33 is completely disengaged from the arc-shaped groove 32 can the corresponding second hinge 17 move. This allows the frame 16 and photovoltaic panel 15 to unfold sequentially, ensuring the stability of the unfolding and installation process. When the photovoltaic panel 15 and frame 16 are folded and stored for transportation, the locking piece 31 is restricted by the arc-shaped locking piece 33, which keeps the second hinge 17 and frame 16 stable during transportation, reducing damage to the photovoltaic panel 15 during transportation.

[0054] By setting locking holes 34 and locking pins 35, when the frame 16 and photovoltaic panel 15 are fully unfolded, the locking pins 35 are engaged into the locking holes 34, and the locking pieces 31 lock and fix the adjacent frames 16, ensuring the shape of the frames 16 after unfolding, and thus ensuring that the frames 16 remain stable during the traction and erection process, avoiding shaking.

[0055] like Figure 1-10 As shown, the bottom of the base plate 10 is fixedly connected to the two sides of the bottom with first hinges 13 respectively. Each first hinge 13 is hinged to a side plate 14. Each end plate 11 is fixedly connected to the two sides of the edge with a latch 40. Each latch 40 can lock the edge of the side plate 14. Each side plate 14 is fixedly connected to the inner side with a support plate 39.

[0056] By setting up a foldable side panel 14, when the side panel 14 is upright, it serves as the side wall of the container consisting of the bottom plate 10, end plate 11, and top plate 12, providing protection for the photovoltaic panel 15 that is folded and stored inside. Furthermore, the support plate 39 supports the photovoltaic panel 15 when it is folded and stored, reducing the damage to the photovoltaic panel 15 caused by shaking during transportation.

[0057] When installing the photovoltaic panel 15, the side panel 14 is folded flat to provide a flat platform for the unfolding process of the frame 16 and the photovoltaic panel 15. This provides more stable support, especially for the initial unfolding process, laying a good foundation for subsequent continuous unfolding and traction laying actions, and improving the stability of the unfolding action.

[0058] In this embodiment, initially, the frame 16 and the photovoltaic panel 15 are in a folded and stored state. The top plate 12 is installed on the top of the end plate 11, and the side plate 14 is erected and locked by the latch 40. At this time, the flexible track 25 is rolled up and stored by the winding wheel 26, and each arc-shaped locking piece 33 is inserted into the corresponding arc-shaped groove 32, so that the locking piece 31 is limited, thereby fixing the position of the second hinge 17 and the frame 16 and preventing them from moving freely. At this time, the whole device is in a cargo box state. The operator can use a crane or other lifting equipment to lift the device and place it on a transport vehicle, and the transport vehicle will transport the device to the designated installation location.

[0059] After the device is transported to the designated location, the operator selects a relatively flat area as the erection position. The operator uses the lifting equipment to place the device at the erection position, then opens the latch 40 to fold the two side plates 14 flat, and then removes the top plate 12 and uses the lifting equipment to remove the top plate 12. Then the operator connects the power supply and control system of each first motor 20 and second motor 30. The operator controls the movement of the first motor 20 and second motor 30 through the wireless controller to perform the unfolding and traction movements.

[0060] During the initial deployment, the operator controls the first motor 20 to drive the drive wheel 21 to rotate, and simultaneously drives the second motor 30 to drive the take-up wheel 26 to rotate through the meshing transmission of the worm gear 29 and the worm wheel 27, releasing the flexible track 25 synchronously. The flexible track 25 is continuously released from the take-up wheel 26 and changes direction through the guide wheel 41. As the first motors 20 on both sides move outward to pull the frame 16 to move and unfold, the flexible track 25 moves together with the first motors 20 and is automatically laid. After all the frames 16 are unfolded and erected, the flexible track 25 is completely released and the take-up wheel 26 and the drive wheel 21 move synchronously, so that the flexible track 25 between the guide wheel 41 and the drive wheel 21 remains taut, preventing the flexible track 25 from sagging or bending.

[0061] During the initial unfolding process, the outermost locking piece 31 rotates with the rotation of the frame 16, and the arc-shaped groove 32 gradually slides along the arc direction and eventually leaves the range of the arc-shaped groove 32. Until the frame 16 is fully extended, the arc-shaped locking piece 33 cuts and completely disengages from the arc-shaped groove 32 to release the restriction on the position of the frame 16 and the second hinge 17. As the first motor 20 continues to pull the frame 16 to move, the unrestricted frame 16 and the second hinge 17 slide outward to proceed to the next unfolding action.

[0062] Subsequently, the first motor 20 continues to pull the frame 16 and photovoltaic panel 15 to move to the far end. The subsequent frame 16 and the second hinge 17 can continue to move because they are not restricted by the locking piece 31 and the arc-shaped locking piece 33, and thus perform the subsequent unfolding action. When this unfolding action is completed, the subsequent locking piece 31 and the arc-shaped locking piece 33 are released from the locked state. This process continues to achieve the sequential unfolding of the frame 16, ensuring the stability of the unfolding process and greatly improving the erection efficiency without the need for manual operation.

[0063] When the frame 16 unfolds, it always unfolds on the flat surface of the side plate 14. The side plate 14 provides a flat and stable platform for this process, which facilitates the initial unfolding action. Due to the support of the first wheel frame 19 and the second wheel frame 22, the bottom of the second hinge 17 is suspended, which allows the second hinge 17 to pass smoothly through the support plate 39 during the movement, avoiding the support plate 39 from obstructing the movement of the second hinge 17 and affecting the unfolding and erection action.

[0064] During the installation process, as the second hinge 17 moves, the driven wheel 23 rolls on the laid flexible track 25. Guided by the flexible track 25 and pulled by the first motor 20, the driven wheel 23 moves forward to the far end. By setting the flexible track 25 to isolate the driven wheel 23 from the ground and provide a smooth movement trajectory, the frame 16 and the photovoltaic panel 15 can slide and unfold more smoothly on the surface of the flexible track 25. This avoids ground stones or weeds from hindering the unfolding process of the frame 16 and the photovoltaic panel 15, thus eliminating the need for manual removal of debris in advance, improving the automation level of photovoltaic panel installation and the stability and smoothness of the unfolding process of the photovoltaic panel 15 and the frame 16.

[0065] By setting the limiter 24, the relative position between the driven wheel 23 and the flexible track 25 can be limited, effectively preventing the flexible track 25 from deforming and causing the driven wheel 23 to detach from the surface of the flexible track 25. It also provides additional support and improves the stability of the second hinge 17 supporting the frame 16 and the photovoltaic panel 15. By setting the parallel link 38, after the initial deployment, the parallel link 38 is tightened and fixed, so that the outermost second hinge 17 always remains horizontal, thereby ensuring that the driving wheel 21 maintains a stable posture for traction.

[0066] During the unfolding of the frame 16, the locking pin 35 tilts along with the frame 16 until it overlaps with the bottom of the locking piece 31. The arc-shaped locking piece 33 will overcome the elasticity of the spring 37 and compress it, causing the locking pin 35 to retract into the frame 16. When the position of the locking hole 34 coincides with the locking pin 35, the spring 37 releases its elasticity and pushes the locking pin 35 into the locking hole 34, so that the frame 16 on both sides of the locking piece 31 is completely locked and fixed, thereby keeping the position and unfolding angle of the unfolded frame 16 stable and unchanged, thus keeping the frame 16 stable during the subsequent traction process.

[0067] When the initial deployment is completed, the first wheel frame 19 and the outermost second hinge 17 will tilt with the tilt of the frame 16, resulting in a height difference between the bottom of the outermost frame 16 and the bottom of the other frames 16. This makes it difficult for the locking hole 34 and the locking pin 35 to be accurately aligned and locked, thus affecting the stability of the subsequent traction and erection process. In order to ensure that the first motor 20 can stably traction the subsequent frame 16 to move, the operator can temporarily turn off the first motor 20 and the second motor 30 when the initial deployment is completed, manually adjust the angle of the outermost second hinge 17 to make it horizontal, and then use tools to tighten the parallel connecting rod 38 for fixation, so that the locking hole 34 and the locking pin 35 can be accurately engaged and locked.

[0068] After installation, each photovoltaic panel 15 can be put into operation. Operators can connect the photovoltaic panels 15 to the energy storage device or power line to generate electricity for operation. In order to ensure the stability of the installation, operators can fix the flexible track 25 again after installation as needed. The flexible track 25 is fixed to the ground by fixing devices such as C-shaped fasteners to improve its support stability.

[0069] The aforementioned first motor 20, second motor 30, etc., are mature existing technologies. The structures in the attached drawings are only for illustration and will not be described in detail here.

[0070] The specification and claims use certain terms to refer to specific components. Those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. This specification and claims do not distinguish components based on differences in name, but rather on differences in function. The term "comprising" throughout the specification and claims is an open-ended term and should be interpreted as "comprising but not limited to."
