Description

Technical Field

[0001] The present invention belongs to the field of mobile photovoltaic devices, and particularly relates to a foldable mobile photovoltaic device with rapid automatic erection. Background Art

[0002] A solar photovoltaic system, also known as photovoltaics, refers to a facility that converts solar energy into direct current electricity using the photovoltaic effect of photovoltaic semiconductor materials. In recent years, due to the increased construction and investment needs of China's power, telecommunications, mobile, and network communication industries, traditional photovoltaic power stations are generally built outdoors and installed on the ground through brackets. Building a photovoltaic power station on the ground requires ground treatment, bracket erection, etc. The construction period is long, the construction load is heavy, and there are many professional divisions such as ground treatment, bracket installation, and photovoltaic panel installation. There are also many problems in professional connection during on-site construction, which has led to the demand for a foldable and easily erected photovoltaic system to support agricultural and water resource management plans, provide auxiliary power for construction sites, emergency areas, and off-grid charging stations, and can also be used as an additional power source to support existing generators or supply power to remote areas. Its ability to operate in grid-connected and off-grid environments further expands its utility and meets the needs of activities, places, and communities that require reliable and sustainable power solutions.

[0003] Most existing solutions involve multiple photovoltaic panels being hinged and folded to ultimately form a structure the same size as a standard container. The folded photovoltaic panels are transported to the designated installation location by a transport vehicle and finally slid and unfolded at the installation location. Before erection, it is usually necessary for personnel to pre-lay tracks in advance to reduce the obstacles of stones, weeds, etc. on the ground that affect the unfolding of the photovoltaic panels, making the process of sliding and unfolding the photovoltaic panels smoother to facilitate the traction and unfolding of the photovoltaic panels for erection.

[0004] Moreover, during the process of unfolding and laying the photovoltaic panels, it is necessary to ensure that each photovoltaic panel performs the unfolding action one by one, which is convenient for operators to control and correct the unfolding and avoid problems such as mutual interference and jamming when the photovoltaic panels are unfolded simultaneously or multiple faults occurring simultaneously and being difficult to eliminate. The locking structures adopted by existing products on the market usually use manual locking and unlocking methods. In the process of erecting the photovoltaic panels, it is necessary for staff to manually unlock them one by one in order to achieve the sequential unfolding of the photovoltaic panels to ensure the stability effect of the erection process. However, this method has a low degree of automation, wastes manpower, and affects the erection speed of the photovoltaic panels.

[0005] The Chinese patent with the publication number CN219780087U discloses a mobile folding solar photovoltaic power generation device, which includes a bottom plate, a front side plate, a rear side plate, and a top plate; a first mounting bracket is provided on the bottom plate, a first telescopic frame and a second telescopic frame are vertically arranged with the first mounting bracket, and the first telescopic frame and the second telescopic frame are arranged at both ends of the first mounting bracket; sliding grooves are provided on the first telescopic frame and the second telescopic frame; a telescopic frame body is provided on the first mounting bracket, and the telescopic frame body includes a solar panel mounting frame for setting 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 through the first connecting plate and the second connecting plate. A support member connected to the slider is provided on the first connecting plate, and the slider is arranged in the sliding groove and can move along the sliding groove. It is transported by a box body, and by using its folding structure, it can be quickly erected on site, saving installation time and achieving the purpose of quickly putting it into use.

[0006] However, the above patent still has the following disadvantages:

[0007] 1. The above patent uses the traditional method of laying tracks in advance and then pulling and unfolding. This not only makes it inconvenient for quick erection, but also requires 3 - 4 workers to carry out the erection work simultaneously. This method will waste a lot of time and manpower.

[0008] 2. There is no locking mechanism between the photovoltaic panels in the above patent. During the process of unfolding and erecting the photovoltaic panels, the unfolded photovoltaic panels cannot be locked, resulting in unstable factors such as shaking when the photovoltaic panels are pulled and unfolded, and it is difficult to ensure the stability of the unfolding and erection process.

[0009] 3. The above patent does not describe the structure for controlling the individual unfolding of the photovoltaic panels, which easily leads to a disorderly unfolding process of the photovoltaic panels. During the unfolding process, the photovoltaic panels are prone to interfere with each other and get stuck, or multiple failures occur simultaneously during simultaneous unfolding and are difficult to troubleshoot, affecting the stability of the unfolding and erection process. Summary of the Invention

[0010] In order to overcome the deficiencies of the prior art, the technical problem to be solved by the present invention is that by providing a flexible track and a first motor, during the process of the frame and the photovoltaic panel being unfolded and erected, while the first motor rotates and pulls, the flexible track can be synchronously laid behind the moving direction of the first motor, realizing an automatic way of laying the flexible track, eliminating the need for pre - manual track laying, greatly saving manpower and time, making the erection efficiency of the photovoltaic panel higher and liberating manual labor, further improving the degree of automation and economy. By providing a locking piece and an arc - shaped locking piece, when the frame is not fully unfolded, the arc - shaped locking piece restricts the corresponding second hinge in place and cannot move. Only after the front - placed frame is fully unfolded and the arc - shaped locking piece is completely disengaged from the arc - shaped groove, the corresponding second hinge can move, thereby realizing the sequential unfolding of the frame and the photovoltaic panel one by one, ensuring the stability of the unfolding and erection process. By providing a locking hole and a locking pin, when the frame and the photovoltaic panel are fully unfolded, the locking pin is snapped into the locking hole, and then the adjacent frames are locked and fixed by the locking piece, ensuring the shape of the frame after unfolding, and thus keeping the frames stable with each other during the traction and erection process, avoiding shaking.

[0011] In order to achieve the above object, the present invention provides the following technical solution: A foldable and mobile photovoltaic device for rapid automatic erection, comprising:

Detailed implementation manners

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

[0040] As Figures 1 - 10 shown, a fast automatic erection folding mobile photovoltaic device includes a bottom plate 10, on which a plurality of frames 16 are provided. Each frame 16 is fixedly connected with a photovoltaic panel 15. The tops of adjacent frames 16 are hinged through a third hinge 18, and the bottoms of adjacent frames 16 are hinged through a second hinge 17. The second hinge 17 in the middle is fixedly connected with the bottom plate 10. The hinged frames 16 can be unfolded in an M shape. End plates 11 are fixedly connected to both ends of the bottom plate 10, and a top plate 12 is detachably arranged on the tops of the two end plates 11.

[0041] By providing the hinged frames 16, it can be made that during transportation, the frames 16 and the photovoltaic panels 15 are folded and stored in the box body composed of the bottom plate 10, the end plates 11 and the top plate 12, which is convenient for transportation. Then during erection, the frames 16 and the photovoltaic panels 15 are unfolded in an M shape, so that the photovoltaic panels 15 can obtain sufficient lighting space, and thus photovoltaic power generation is realized to support agricultural and water resource management plans to provide auxiliary power for construction sites, emergency areas and off-grid charging stations.

[0042] As Figures 1 - 10As shown in the figure, four sets of winding wheels 26 are rotatably arranged on the inner sides of the end plates 11. Each set of winding wheels 26 includes two winding wheels 26 arranged vertically. Each set of winding wheels 26 winds and stores a flexible track 25. One end of the flexible track 25 away from the winding wheel 26 is fixedly connected to the bottom plate 10. Each flexible track 25 is arranged at both ends of the frame 16. At both ends of the bottoms of the outermost two second hinges 17, first wheel frames 19 are respectively fixedly connected. On one side of each first wheel frame 19, a first motor 20 is fixedly connected. The power output end of each first motor 20 passes through the first wheel frame 19 and is drivingly connected to a first motor 20. Each first motor 20 is drivingly connected to the corresponding flexible track 25.

[0043] By arranging the flexible track 25 and the first motor 20, during the process of deploying and erecting the frame 16 and the photovoltaic panel 15, while the first motor 20 rotates and pulls, the flexible track 25 can be synchronously laid behind the moving direction of the first motor 20, which is convenient for guiding the subsequent movement of the frame 16 and the photovoltaic panel 15 and improves the smoothness of the erection process.

[0044] Moreover, through the traction and laying of the first motor 20 in cooperation with the simultaneous unwinding of the winding wheels 26, the flexible track 25 can be automatically laid, eliminating the need for manual pre-laying of the track, greatly saving manpower and time, making the erection efficiency of the photovoltaic panel 15 higher and liberating manual labor, further improving the automation degree and economy.

[0045] As Figures 1 - 10 shown in the figure, except for the second hinges 17 located in the middle and the outermost ones, at both ends of the bottoms of the remaining second hinges 17, second wheel frames 22 are respectively fixedly connected. On one side of each second wheel frame 22, a driven wheel 23 is rotatably connected. Each driven wheel 23 is in rolling connection with the corresponding flexible track 25. On the surface of each second wheel frame 22, limiters 24 are respectively fixedly connected on both sides of the driven wheel 23. Each limiter 24 is in fitting and sliding connection with the corresponding flexible track 25. A parallel link 38 is hinged between the outermost second hinge 17 and the adjacent frame 16.

[0046] By arranging the driven wheels 23, the flexible track 25 isolates the driven wheels 23 from the ground and provides a smooth moving track, enabling the frame 16 and the photovoltaic panel 15 to slide and unfold more smoothly on the surface of the flexible track 25, avoiding the obstruction of the frame 16 and the photovoltaic panel 15 from the ground stones or weeds during the unfolding process, thus eliminating the need for manual pre-removal of debris and improving the automation degree of the photovoltaic panel erection and the stability and smoothness of the unfolding process of the photovoltaic panel 15 and the frame 16.

[0047] By setting the stopper 24, the relative position between the driven wheel 23 and the flexible track 25 can be restricted, effectively preventing the flexible track 25 from deforming and causing the driven wheel 23 to disengage from the surface of the flexible track 25. Additionally, it provides extra support to improve the stability of the second hinge 17 supporting the frame 16 and the photovoltaic panel 15. By setting the parallel link 38 and tightening and fixing the parallel link 38 after the initial deployment, the outermost second hinge 17 is always kept horizontal, thereby ensuring that the driving wheel 21 maintains a stable posture for traction.

[0048] As Figures 1 - 10 shown, the flexible track 25 is made of rubber material, with steel wires embedded therein, and the surface of the flexible track 25 for contacting the ground is rough.

[0049] The flexible track 25 being made of rubber material can meet the requirement of being curled and stored. By embedding steel wires in the flexible track 25, its ability to resist tensile deformation is improved, thus preventing the flexible track 25 from undergoing elastic deformation due to pulling during the process of the first motor 20 pulling the flexible track 25, which may otherwise cause the flexible track 25 to deform and make it difficult to stably guide the subsequent deployment of the photovoltaic panel 15 and the frame 16. Moreover, the surface of the flexible track 25 for contacting the ground is set to be rough, effectively increasing the friction between the flexible track 25 and the ground and improving the stability of the flexible track 25 in supporting and guiding the photovoltaic panel 15 and the frame 16 after laying.

[0050] As Figures 1 - 10 shown, the rotating shaft of one of the reel wheels 26 in each set of reel wheels 26 passes through the box body and is fixedly connected with a worm gear 27. A set of rod seats 28 are fixedly connected to the outer wall of the box body at positions corresponding to each worm gear 27. A worm 29 meshing with the worm gear 27 is rotatably connected in each set of rod seats 28. One end of each set of rod seats 28 is fixedly connected with a second motor 30, and the power output end of each second motor 30 is drivingly connected with the corresponding worm 29.

[0051] By setting the worm gear 27 and the worm 29, the function of driving the reel wheel 26 to rotate and unwind is realized, thereby cooperating with the traction of the first motor 20 to achieve the effect of automatically laying the flexible track 25.

[0052] As Figures 1 - 10As shown in the figure, locking pieces 31 are fixedly connected to both ends of the bottom of every other frame 16. The locking pieces 31 on both sides of the bottom plate 10 are symmetrically arranged. An arc-shaped groove 32 is formed on each locking piece 31. 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 be slidably connected to the corresponding arc-shaped groove 32. After the frame 16 is fully unfolded, the arc-shaped locking piece 33 can just completely disengage from the arc-shaped groove 32. A locking hole 34 is formed at the bottom end of each locking piece 31. Pin seats 36 are fixedly connected to both ends of the bottom of each frame 16 without a locking piece 31. A locking pin 35 is slidably connected in each pin seat 36. A spring 37 is arranged 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 penetrate into the corresponding locking hole 34 for clamping.

[0053] By arranging the locking piece 31 and the arc-shaped locking piece 33, when the frame 16 is not fully unfolded, the arc-shaped locking piece 33 restricts the corresponding second hinge 17 in place and cannot move. Only after the previous frame 16 is fully unfolded and the arc-shaped locking piece 33 is completely disengaged from the arc-shaped groove 32, the corresponding second hinge 17 can move, thereby realizing the sequential unfolding of the frame 16 and the photovoltaic panel 15 one by one, ensuring the stability of the unfolding and erection process. When the photovoltaic panel 15 and the frame 16 are folded and stored for transportation, the locking piece 31 is restricted by the arc-shaped locking piece 33, so that the second hinge 17 and the frame 16 remain stable during transportation, reducing the damage to the photovoltaic panel 15 during transportation.

[0054] By arranging the locking hole 34 and the locking pin 35, when the frame 16 and the photovoltaic panel 15 are fully unfolded, the locking pin 35 is clamped into the locking hole 34, and then the adjacent frames 16 are locked and fixed through the locking piece 31, ensuring the shape of the frame 16 after unfolding, and further making the frames 16 always remain stable between each other during the traction and erection process, avoiding shaking.

[0055] As Figures 1 - 10 shown in the figure, first hinges 13 are fixedly connected to both sides of the bottom of the bottom plate 10. Each first hinge 13 is hinged with a side plate 14. Locking buckles 40 are fixedly connected to the edges of both sides of each end plate 11. Each locking buckle 40 can lock the edge of the side plate 14. A support plate 39 is fixedly connected to the inner side of each side plate 14.

[0056] By arranging the foldable side plates 14, when the side plates 14 are erected, they serve as the side walls of the box body composed of the bottom plate 10, the end plates 11 and the top plate 12, providing protection for the internally folded and stored photovoltaic panel 15, and using the support plate 39 to support the photovoltaic panel 15 during folding and storage, reducing the damage to the photovoltaic panel 15 caused by shaking during transportation.

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

[0058] In this embodiment, initially, the frame 16 and the photovoltaic panel 15 are in a folded storage state, the top plate 12 is installed on the top of the end plate 11, and the side plate 14 is erected and fixed by the lock 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 and the position of the second hinge 17 and the frame 16 is fixed and cannot be moved at will. At this time, the whole device is in a cargo box state, and the operator can lift the device through a crane or other lifting equipment and place it on a transport vehicle, and the transport vehicle transports 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 installation location, and uses a lifting device to place the device at the installation location. The operator then opens the lock 40 to fold and lay the side panels 14 on both sides flat, and then removes the top panel 12 and uses the lifting device to remove the top panel 12. The operator then connects the power supply and control system of each first motor 20 and the second motor 30, and the operator controls the actions of the first motor 20 and the second motor 30 through a wireless controller to perform unfolding and towing actions.

[0060] When performing the initial unfolding action, the operator controls the first motor 20 to drive the driving wheel 21 to rotate and at the same time drives the second motor 30 to drive the winding wheel 26 to rotate through the meshing transmission of the worm 29 and the worm wheel 27 to synchronously release the flexible track 25. The flexible track 25 is continuously released from the winding wheel 26 and changes direction through the guide wheel 41. While the first motors 20 on both sides move outward to pull the frame 16 to move and unfold, the flexible track 25 moves with the first motor 20 and is automatically laid. After all the frames 16 are unfolded and erected, the flexible track 25 is completely released and the winding wheel 26 moves synchronously with the driving wheel 21, so that the flexible track 25 between the guide wheel 41 and the driving wheel 21 remains in a straight state to prevent the flexible track 25 from sagging and bending.

[0061] During the initial unfolding action, the outermost locking piece 31 rotates with the rotation of the frame 16, and the arc groove 32 gradually slides along the arc direction and finally leaves the range of the arc groove 32, until the frame 16 is fully stretched and the arc locking piece 33 is completely disengaged from the arc 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 frame 16 and the second hinge 17 that are freed from the restriction slide outward to perform the next unfolding action.

[0062] Then the first motor 20 continues to pull the frame 16 and the photovoltaic panel 15 to move toward the far end, and 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 then the subsequent unfolding action is performed. When this unfolding action is completed, the subsequent locking piece 31 and the arc-shaped locking piece 33 are released from the locked state. In this way, the frames 16 are unfolded one by one in sequence, ensuring the stability of the unfolding process and greatly improving the erection efficiency without the need for manual operation by personnel.

[0063] When the frame 16 is unfolding, it is always unfolded on the flat surface of the side panel 14. The side panel 14 provides a flat and stable platform for this process, which facilitates the stable 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 in the air, so that the second hinge 17 can pass through the support plate 39 smoothly during the movement, thereby preventing the support plate 39 from hindering the movement of the second hinge 17 and affecting the unfolding and erecting action.

[0064] During the erection process, the second hinge 17 moves while the driven wheel 23 rolls on the laid flexible track 25. The driven wheel 23 is guided by the flexible track 25 and pulled by the first motor 20 in front to move forward to the far end. By setting the flexible track 25 to isolate the driven wheel 23 from the ground and provide a smooth moving trajectory, the frame 16 and the photovoltaic panel 15 can slide and unfold more smoothly on the surface of the flexible track 25, avoiding stones or weeds on the ground from hindering the unfolding process of the frame 16 and the photovoltaic panel 15, and there is no need to manually remove debris in advance, thereby improving the degree of automation of the photovoltaic panel erection 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, and providing additional support to improve the stability of the second hinge 17 support frame 16 and the photovoltaic panel 15. By setting the parallel link 38, the parallel link 38 is tightened and fixed after the initial deployment, 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 process of the frame 16, the locking pin 35 tilts together with the frame 16 until the bottom end of the locking pin 35 overlaps with the bottom end of the locking piece 31. The arc-shaped locking piece 33 will compress the spring 37 against its elasticity and retract the locking pin 35 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, and further keeping the frame 16 stable during the subsequent traction process.

[0067] When the initial unfolding action is completed, the first wheel carrier 19 and the outermost second hinge 17 will tilt with the tilt of the frame 16, resulting in a height difference between the bottom end height of the outermost frame 16 and the bottom ends of the other frames 16, making 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 erection process. 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 unfolding action is completed, manually adjust the angle of the outermost second hinge 17 to be horizontal, and then use tools to tighten and fix the parallel link 38, so that the locking hole 34 and the locking pin 35 can be accurately engaged and locked.

[0068] After the erection is completed, each photovoltaic panel 15 can be put into work. The operator can connect the photovoltaic panel 15 to the energy storage device or the power consumption circuit to generate electrical energy for work. To ensure the stability of the erection, the operator can re-fix the flexible track 25 after erection according to needs, and fix the flexible track 25 on the ground through fixing devices such as C-shaped buckles to improve its support stability.
