Description

Technical Field

[0001] This invention belongs to the field of photovoltaic brackets, specifically an adjustable photovoltaic bracket. Background Technology

[0002] Photovoltaic panels, scientifically known as solar panels, are the core power generation components of photovoltaic power generation systems. They utilize the photovoltaic effect of semiconductor materials to directly convert sunlight into direct current (DC) electricity. Photovoltaic support structures, formally known as solar photovoltaic support systems, are special structures specifically designed for the safe, reliable, and long-term fixing, installation, and support of photovoltaic modules. The main functions of photovoltaic (PV) mounting systems are: to provide a stable installation foundation for PV modules; to resist natural forces such as wind loads, snow loads, and earthquakes, ensuring system safety; and to provide a good ventilation and heat dissipation environment by raising the modules off the ground or roof, and to avoid water accumulation and debris buildup, thereby extending the lifespan of the modules.

[0003] Traditional floating solar panels are generally divided into fixed and floating types. Fixed types require underwater piling to form a stable support structure to ensure the stability and safety of the solar panels. However, the investment cost is too high. Although fixed supports are more impact-resistant, they are difficult and costly to dismantle when the area is no longer in use. They are often left in the water, which puts a burden on the subsequent reuse of the water. Floating supports, on the other hand, lack stable support. In order to resist strong winds and other severe weather, they need to be secured by shore tensioning and numerous underwater anchor points. Even so, due to the lack of a fixed support structure, it is still difficult to guarantee the safety of the supports and solar panels.

[0004] Therefore, the present invention provides an adjustable photovoltaic bracket. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: An adjustable photovoltaic support according to the present invention includes a folding frame, the folding frame is composed of multiple holding plates that can be flipped and folded, the top surface of the holding plates is provided with multiple mounting grooves for fixing photovoltaic panels, a float is provided in the middle of the folding frame, the center of gravity of the float is located at its bottom, and a water pump for pumping water and draining water is installed at the bottom of the float. This setup achieves comprehensive and safe photovoltaic integration. Not only is the overall structure of the support system simple and the initial investment cost low, but it also allows the photovoltaic panels to be submerged underwater during severe weather, avoiding the impact of wind, sand, and gravel. Because the water absorbs a significant amount of external force, the underwater support system only requires simple pulling and securing to maintain its position. After the severe weather, it can float back to the surface and continue generating electricity, ensuring the safety and lifespan of the photovoltaic panels. Furthermore, the support system is easy to install; it can be used simply by being submerged in water. Multiple support systems are typically placed side-by-side and connected to form a large-area photovoltaic project, increasing the utilization rate of the water surface.

[0007] Preferably, the float consists of a water tank and a center of gravity bladder. The center of gravity bladder is fixed to the bottom of the water tank, which is hollow. The water pump is fixed in the center of gravity bladder and communicates with the inside of the water tank. During operation, the float's structure allows its center of gravity to point downwards, providing downward force at the bottom, while the water tank above provides buoyancy. At the same time, it is necessary to ensure that part of the top of the water tank is exposed above the water surface, thus forming a stable shape and ensuring the horizontal opening and vertical closing of the folding frame.

[0008] Preferably, a top float is installed on the top of the water tank. The top float is hollow, and a wind measuring plate is rotatably connected to its top. A floating roller is fixed to the outer edge of the holding plate. During operation, to reduce the risk of the entire device sinking due to incorrect operation during buoyancy adjustments, a hollow top float is installed on the top of the water tank. This ensures that the top float remains on the water surface after the entire support structure is submerged, serving both as a position marker and maintaining the stability of the device only when a portion of the support structure is above the water surface. The wind measuring plate has multiple facets. It rotates under the influence of wind, thereby monitoring the wind level in real time. When the wind level is too high, it transmits information to cause the retractable frame to retract and sink. At the same time, since the wind measuring plate is installed above the top buoy, it is always kept above the water surface. When the wind level decreases, it transmits information again to control the retractable frame to rise. The floating rollers provide buoyancy to the edges of the retractable frame and also assist in the unfolding process when the retractable frame is unfolded, while ensuring that the edges of the retractable frame are above the water surface after final unfolding. It should be noted that after the retractable frame is retracted, the buoyancy of the water tank can be adjusted appropriately to ensure that the retractable frame is completely submerged underwater.

[0009] Preferably, the folding frame is square, and the holding plates are triangular. There are eight holding plates in total, arranged in pairs. The two holding plates in each pair form a square structure. The two holding plates in each pair are rotatably connected, and the holding plates in adjacent pairs are also rotatably connected. During operation, the folding process of the folding frame can be as follows: the two symmetrically arranged holding plates in each pair rotate around the line of symmetry as the axis, the right-angle ends of the two holding plates flip downward, and the hypotenuses tilt downward as a whole, thereby folding all the holding plates downward to achieve the effect of the folding frame submerging underwater. The unfolding of the folding frame is achieved by reversing the operation. This method requires all adjacent holding plates to be rotatably connected to achieve this.

[0010] Preferably, both sides of the holding plate are fixedly connected with collars. A rotatable horizontal bar is provided between two holding plates in each group. The collars are rotatably engaged with the outside of the horizontal bar at corresponding positions. An adjustable shaft is provided between adjacent groups of holding plates. The collars are rotatably engaged with the outside of the adjustable shaft at corresponding positions. During operation, the collars allow each adjacent holding plate to be rotatably connected while maintaining a certain gap to ensure smooth rotation of the holding plates. At the same time, the gap ensures the thickness of the holding plates. By increasing the thickness, the impact of water splashes and ripples can be reduced when the retrieval frame is laid flat on the water surface. When the retrieval frame is retracted, the horizontal bar tilts downward with the end near the float as the pivot point, causing the inclined side of the holding plate to tilt downward as a whole. At the same time, the collars rotate outside the adjustable shaft, ultimately allowing the holding plate to complete the angle adjustment and the retrieval process of the retrieval frame to be completed.

[0011] Preferably, a connecting column is fixedly connected between the water tank and the top float. A lifting sleeve capable of raising and lowering is slidably connected to the outside of the water tank. A transmission arm is rotatably connected to the bottom of the adjusting shaft. The transmission arm is rotatably connected to the outside of the connecting column and the outside of the lifting sleeve. During operation, the lowering of the lifting sleeve drives the transmission arm to move downward. At the same time, the two ends of the transmission arm rotate adaptively, thereby pulling the adjusting shaft downward and simultaneously pulling the horizontal bar downward. Finally, the folding operation is completed under the adaptive rotation of the holding plate. When it is necessary to unfold, simply lift the lifting sleeve to complete the opening operation.

[0012] Preferably, an electric winding reel is fixedly connected inside the center of gravity bladder. Multiple cables are wound around the outside of the electric winding reel. The top of the cables is fixedly connected to the bottom of the lifting sleeve. The inside of the lifting sleeve is hollow. A groove is also provided on the outside of the water tank to limit the rotation of the transmission arm. During operation, the electric winding reel rotates and pulls the cables, thereby dragging the lifting sleeve downward, thus realizing the folding operation of the folding frame. When the electric winding frame releases the cables, due to the hollow interior of the lifting sleeve, it will move upward under the action of buoyancy. At the same time, under the action of the floating roller, the edge of the holding plate will also move upward, so that the folding frame can open automatically.

[0013] Preferably, four nozzles are fixed to the top of the outer side of the water tank. The nozzles are connected to a water pump and aligned with the gaps in the center of the folded retractable frame. An elastic baffle is fixed to the top surface of the holding plate. During operation, when the holding plate sinks underwater, the water flow can clean dust and other stains from the surface of the waterproof membrane. Water can also be pumped in by the water pump and sprayed outward through the nozzles. The water flow passes through the gaps between the holding plates, acting on the water to create turbulence, which can effectively clean the outer surface. The elastic baffle separates the sprayed water flow vertically, forming more complex turbulence, improving the cleaning effect and reducing the loss of impact force. With this configuration, the retractable frame can sink periodically to clean the surface of the photovoltaic panel, and the water source is readily available, making it simpler and more convenient than traditional cleaning methods.

[0014] Preferably, the outer side of the top float is fixed with multiple connecting buckles, which are arranged in a ring at equal intervals. Adjacent top floats are connected by connecting cables. During operation, the connecting cables are used to fix adjacent top floats, which can form a stable large-area photovoltaic area. The top floats are always above the water surface. Even if the support sinks, the connecting cables will remain above the water surface, providing a stable fixing function. Finally, the end connecting cables are fixed to the shore or piles to stabilize all supports.

[0015] Preferably, a vertical chain is provided at the bottom of the center of gravity bladder, and a fixed anchor is fixedly connected to the bottom of the vertical chain. A buckle that connects with the vertical chain is fixedly connected to the bottom of the center of gravity bladder. During operation, the vertical chain is provided at the bottom of some of the center of gravity bladders and fixed with the fixed anchor to ensure the stability of the support. Often, it is only necessary to provide it at the bottom of the support at the edge. It is necessary to ensure that the length of the vertical chain is longer than the water depth so that it will not affect the up and down movement of the float.

[0016] The beneficial effects of this invention are as follows: 1. The adjustable photovoltaic support structure described in this invention achieves comprehensive and safe photovoltaic installation. Not only is the overall structure simple and the initial investment cost low, but it can also be submerged underwater with the photovoltaic panels during severe weather to avoid impacts from wind, sand, and gravel. Because the water absorbs a significant amount of external force, the underwater support only requires simple pulling and fixing to maintain its position. After the severe weather, it can float back to the surface and continue photovoltaic power generation, ensuring the safety and lifespan of the photovoltaic panels. Furthermore, the support is easy to install; it can be used simply by being submerged in water. Multiple supports are typically placed side-by-side and connected to form a large-area photovoltaic project, improving the utilization rate of the water surface.

[0017] 2. The adjustable photovoltaic support described in this invention features a hollow top float on the top of the water tank. This ensures that the top float remains above the water surface after the entire support is submerged, serving both as a position marker and maintaining the stability of the equipment only when a portion of the support is above the water. The anemometer has multiple facets and rotates under wind conditions to monitor the wind level in real time. When the wind level is too high, it transmits information to retract and lower the retractable frame. Since the anemometer is mounted above the top float, it remains above the water surface. When the wind level decreases, it transmits information to control the retractable frame to rise. The floating rollers provide buoyancy to the edges of the retractable frame and assist in the unfolding process, ensuring that the edges of the retractable frame remain above the water surface after final unfolding.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 2As shown in the embodiment of the present invention, an adjustable photovoltaic support includes a folding frame 1, which is composed of multiple flip-up and foldable holding plates 6. The top surface of the holding plates 6 is provided with multiple mounting grooves 7 for fixing photovoltaic panels. A float 2 is provided in the middle of the folding frame 1. The center of gravity of the float 2 is located at its bottom. A water pump 25 for pumping and draining water is installed at the bottom of the float 2. The retractable frame 1 is unfolded and laid flat, and the support is placed directly into the water, with buoyancy provided by the float 2. Since the center of gravity of the float 2 is located at the bottom, the entire float 2 is cylindrical, and the retractable frame 1 is on top, so the center of buoyancy is located at the top of the entire support. Therefore, when the support is in the water, the entire float 2 will be vertical in the water, while the retractable frame 1 can be exposed above the water surface. The photovoltaic panels are installed in the mounting groove 7 and kept above the water surface for normal photovoltaic function. When encountering strong winds or other severe weather, the entire retractable frame 1 is controlled to retract inward, specifically by each holding panel 6 rotating around its two edges as axes. Folding and flipping at a certain angle causes each holding plate 6 to tilt downwards. At this point, the overall shape of the support structure changes, but the overall buoyancy and center of gravity remain unchanged. The center of buoyancy is slightly adjusted upwards, causing the top of the float 2 to move upwards a certain distance, while the entire retractable frame 1 is below the water surface. It is important to note that the photovoltaic panels need to be waterproofed. Alternatively, after installation, a film can be applied directly to the outside of the holding plate 6 to ensure sealing and watertightness. After the severe weather has passed, the entire retractable frame 1 is unfolded, allowing the photovoltaic panels to re-emerge above the water surface for photovoltaic effect. To ensure the support structure is upright... In common use, water pump 25 pumps water in and out, controlling the buoyancy of the float 2. For example, by adjusting the buoyancy, the bottom of the retractable frame 1 can be made flush with the water surface. The thickness of the holding plate 6 can prevent the impact of water surface fluctuations on the photovoltaic panel under normal weather conditions, ensuring the smooth operation of the photovoltaic panel. Furthermore, when the retractable frame 1 is retracted, the buoyancy of the entire support structure can be reduced, ensuring that the retractable frame 1 is below the water body, with the top of part of the float 2 exposed above the water surface. This allows the entire support structure to form a vertical, self-sustaining shape, preventing water fluctuations from affecting the equipment's form. Through this design, a comprehensive and safe photovoltaic installation effect is achieved. Not only... The support structure is simple, with low initial investment costs. It can be submerged underwater with the photovoltaic panels during severe weather to avoid impacts from wind, sand, and gravel. Because the water absorbs a significant amount of external force, the underwater support only requires simple pulling and securing to maintain its position. After the severe weather, it can float back to the surface and continue generating electricity, ensuring the safety and lifespan of the photovoltaic panels. Furthermore, the support is easy to install; it can be used simply by being submerged in water. Multiple supports are typically placed side-by-side and connected to form a large-area photovoltaic project, maximizing the utilization of the water surface.

[0022] The float 2 consists of a water tank 12 and a center of gravity 11. The center of gravity 11 is fixed to the bottom of the water tank 12. The water tank 12 is hollow. The water pump 25 is fixed in the center of gravity 11 and communicates with the inside of the water tank 12. During operation, the structure of the float 2 is designed so that its center of gravity is downward, providing downward force at the bottom, while the water tank 12 above provides buoyancy. At the same time, it is necessary to ensure that the top of part of the water tank 12 is exposed above the water surface, so as to form a stable shape and ensure the horizontal opening and vertical closing of the retracting frame 1.

[0023] The top of the water tank 12 is equipped with a top float ball 16, the top float ball 16 is hollow inside, and the top of the top float ball 16 is rotatably connected to a wind measuring plate 17. The outer edge of the holding plate 6 is fixed with a floating roller 8. To minimize the risk of the entire device sinking due to incorrect operation during buoyancy adjustments, a hollow top float 16 is installed on the top of the water tank 12. This ensures that the top float 16 remains on the water surface after the entire support structure is submerged, serving both as a position marker and maintaining the device's structural stability only when a portion of the support structure is above water. The anemometer 17 has multiple facets and rotates under wind conditions to monitor wind speed in real time. When the wind speed is too high, it transmits... Information is sent to the retractable frame 1 to retract and sink. At the same time, since the wind measuring plate 17 is installed above the top float 16, it is always kept above the water surface. When the wind force decreases, information is sent to control the retractable frame 1 to rise. The float roller 8 provides buoyancy to the edge of the retractable frame 1 and assists in the unfolding process when the retractable frame 1 is unfolded, while ensuring that the edge of the retractable frame 1 is above the water surface after it is finally unfolded. It should be noted that after the retractable frame 1 is retracted, the buoyancy of the water tank 12 can be adjusted appropriately to ensure that the retractable frame 1 is completely submerged underwater.

[0024] The gathering frame 1 is square in shape, and the holding plate 6 is triangular in shape. There are eight holding plates 6 in total, and they are arranged in pairs. The two holding plates 6 in each pair form a square structure. The two holding plates 6 in each pair are rotatably connected, and the holding plates 6 in adjacent pairs are also rotatably connected. During operation, the folding process of the folding frame 1 can be as follows: the two symmetrically arranged holding plates 6 in each group rotate around the line of symmetry as the axis, the right-angle ends of the two holding plates 6 flip downwards, and the hypotenuses tilt downwards as a whole, thereby folding all the holding plates 6 downwards and completing the effect of the folding frame 1 submerging underwater; the unfolding of the folding frame 1 can be done by reversing the operation. This method requires all adjacent holding plates 6 to be rotated and connected to achieve this.

[0025] Both sides of the holding plate 6 are fixed with collars 21. A rotatable horizontal rod 19 is provided between two holding plates 6 in each group. The collars 21 are rotatably engaged with the outside of the horizontal rod 19 at the corresponding positions. An adjustable shaft 20 is provided between the holding plates 6 in adjacent groups. The collars 21 are rotatably engaged with the outside of the adjustable shaft 20 at the corresponding positions. During operation, the collar 21 allows each adjacent holding plate 6 to rotate and connect while maintaining a certain gap, ensuring the smooth rotation of the holding plate 6. The gap also ensures the thickness of the holding plate 6. Increasing the thickness reduces the impact of splashes and ripples when the gathering frame 1 is laid flat on the water surface. When the gathering frame 1 is retracted, the horizontal bar 19 tilts downward with the end near the float 2 as the pivot point, causing the inclined side of the holding plate 6 to tilt downward as a whole. At the same time, the collar 21 rotates outside the adjusting shaft 20, ultimately allowing the holding plate 6 to complete the angle adjustment and the retraction process of the gathering frame 1 to be completed.

[0026] A connecting column 24 is fixedly connected between the water tank 12 and the top float 16. A lifting sleeve 14 capable of lifting and lowering is slidably connected to the outside of the water tank 12. A transmission arm 15 is rotatably connected to the bottom of the adjusting shaft 20. The transmission arm 15 is rotatably connected to the outside of the connecting column 24 and the outside of the lifting sleeve 14. During operation, the lifting sleeve 14 sinks, driving the transmission arm 15 to move downward. At the same time, the two ends of the transmission arm 15 rotate adaptively, which in turn pulls the adjusting shaft 20 to move downward and simultaneously pulls the horizontal bar 19 to swing downward. Finally, the folding work is completed under the adaptive rotation of the holding plate 6. When it needs to be unfolded, simply lift the lifting sleeve 14 to complete the opening work.

[0027] An electric winding reel is fixed inside the center of gravity bladder 11. Multiple cables 10 are wound around the outside of the electric winding reel. The top of the cables 10 is fixed to the bottom of the lifting sleeve 14. The lifting sleeve 14 is hollow inside. A groove 13 for limiting the rotation of the transmission arm 15 is also provided on the outside of the water tank 12. During operation, the electric winding reel rotates and pulls the cable 10, which in turn drags the lifting sleeve 14 downward, thereby achieving the winding of the winding frame 1. When the electric winding frame releases the cable 10, the lifting sleeve 14, being hollow inside, will move upward under the action of buoyancy. At the same time, under the action of the floating roller 8, the edge of the holding plate 6 will also move upward, allowing the winding frame 1 to open automatically.

[0028] Four nozzles 22 are fixedly connected to the top of the outer side of the water tank 12. The nozzles 22 are connected to the water pump 25. The nozzles 22 are aligned with the gap in the middle space of the folded frame 1. An elastic material blocking piece 9 is fixedly connected to the top surface of the holding plate 6. During operation, when the holding plate 6 sinks underwater, the water flow can clean dust and other stains from the surface of the waterproof membrane. Water can also be drawn in by the water pump 25 and sprayed outward through the nozzle 22. The water flow passes through the gaps between the holding plates 6 and acts on the water, creating turbulence, which can effectively clean the outer surface. The elastic blocking plate 9 separates the sprayed water flow into vertical and horizontal directions, forming a more complex turbulence, improving the cleaning effect and reducing the loss of impact force. With this configuration, the retraction frame 1 can sink periodically to complete the cleaning of the photovoltaic panel surface, and the water source is readily available, making it simpler and more convenient than traditional cleaning methods.

[0029] Multiple connecting buckles 18 are fixed to the outer side of the top float 16. The multiple connecting buckles 18 are arranged in a ring at equal intervals. Adjacent top floats 16 are connected by connecting cables 5. During operation, the connecting cables 5 are used to fix adjacent top floats 16, which can form a stable large-area photovoltaic area. The top floats 16 are always above the water surface. Even if the support sinks, the connecting cables 5 will remain above the water surface, providing a stable fixing function. Finally, the end connecting cables 5 are fixed to the shore or pile to stabilize all supports.

[0030] The bottom of the center of gravity bladder 11 is provided with a vertical chain 3, the bottom of the vertical chain 3 is fixedly connected with a fixed anchor 4, and the bottom of the center of gravity bladder 11 is fixedly connected with a buckle that connects with the vertical chain 3. During operation, a vertical chain 3 is installed at the bottom of part of the center of gravity 11 and fixed with a fixed anchor 4 to ensure the stability of the support. Often, it is only necessary to install it at the bottom of the support at the edge. It is necessary to ensure that the length of the vertical chain 3 is longer than the water depth so that the float 2 will not be affected when it moves up and down.

[0031] During operation, the retractable frame 1 is unfolded and laid flat, and the support is placed directly into the water, where buoyancy is provided by the float 2. Since the center of gravity of the float 2 is located at the bottom, the entire float 2 is cylindrical, and the retractable frame 1 is positioned above it, ensuring the center of buoyancy is at the top of the entire support. Therefore, when the support is in the water, the entire float 2 remains vertical, while the retractable frame 1 remains above the water surface. The photovoltaic panels are installed in the mounting groove 7, remaining above the water surface for normal photovoltaic function. In case of strong winds or other severe weather, the entire retractable frame 1 is retracted inwards, specifically by rotating each holding panel 6 around its two edges. The shaft is folded and flipped at a certain angle, causing each holding plate 6 to tilt downwards. At this point, the overall shape of the support changes, but the overall buoyancy and center of gravity remain unchanged. The center of buoyancy is slightly adjusted upwards, causing the top of the float 2 to move upwards a certain distance, while the entire retractable frame 1 is below the water surface. It is important to note that the photovoltaic panels need to be waterproofed. Alternatively, after installing the photovoltaic panels, a film can be directly applied to the outside of the holding plate 6 to ensure sealing and watertightness. After the severe weather passes, the entire retractable frame 1 is unfolded, allowing the photovoltaic panels to re-emerge above the water surface for photovoltaic effect. To ensure the support... When the frame is in normal use, water is pumped in and out using water pump 25, and the buoyancy of the floats 2 is controlled. For example, by adjusting the buoyancy, the bottom surface of the retractable frame 1 can be made flush with the water surface, and the thickness of the holding plate 6 can be adjusted to prevent the impact of water surface fluctuations on the photovoltaic panels under normal weather conditions, ensuring the smooth operation of the photovoltaic panels. Furthermore, when the retractable frame 1 is retracted, the buoyancy of the entire frame can be reduced, ensuring that the retractable frame 1 is submerged in the water, with the top of part of the floats 2 exposed above the water surface, allowing the entire frame to form a vertical, self-sustaining shape, preventing water fluctuations from affecting the equipment's form. Through this design, a comprehensive and safe photovoltaic installation is achieved. The support structure is simple, with low initial investment costs. It can be submerged underwater with the photovoltaic panels during severe weather to avoid impacts from wind, sand, and gravel. Because the water absorbs a significant amount of external force, the underwater support only requires simple pulling and securing to maintain its position. After the severe weather, it can float back to the surface and continue generating electricity, ensuring the safety and lifespan of the photovoltaic panels. Furthermore, the support is easy to install; it can be used simply by being submerged in water. Multiple supports are typically placed side-by-side and connected to form a large-area photovoltaic project, maximizing the utilization of the water surface.

[0032] The structure of the float 2 is designed so that its center of gravity is downward, providing downward force at the bottom, while the water tank 12 above provides buoyancy. At the same time, it is necessary to ensure that the top of part of the water tank 12 is exposed above the water surface, so as to form a stable shape and ensure the horizontal opening and vertical closing of the retracting frame 1.

[0033] To reduce the risk of the entire device sinking due to incorrect operation during buoyancy adjustments, a hollow top float 16 is installed on the top of the water tank 12. This ensures that the top float 16 remains on the water surface after the entire support structure is submerged, serving both as a position marker and maintaining the device's structural stability only when a portion of the support structure is above the water. The anemometer 17 has multiple facets and rotates under wind conditions to monitor wind speed in real time. When the wind speed is too high, it transmits information. The retractable frame 1 is retracted and sunk. Meanwhile, since the wind measuring plate 17 is installed above the top float 16, it is always kept above the water surface. When the wind force decreases, it transmits information to control the retractable frame 1 to rise. The float roller 8 provides buoyancy to the edge of the retractable frame 1 and assists in the unfolding process when the retractable frame 1 is unfolded, while ensuring that the edge of the retractable frame 1 is above the water surface after final unfolding. It should be noted that after the retractable frame 1 is retracted, the buoyancy of the water tank 12 can be adjusted appropriately to ensure that the retractable frame 1 is completely submerged underwater.

[0034] The folding process of the folding frame 1 can be as follows: the two symmetrically arranged holding plates 6 in each group rotate around the axis of symmetry, the right-angle ends of the two holding plates 6 flip downwards, and the hypotenuses tilt downwards as a whole, thereby folding all the holding plates 6 downwards and completing the effect of the folding frame 1 submerging underwater; the folding frame 1 can be unfolded by reversing the operation. This method requires all adjacent holding plates 6 to be rotated and connected to achieve this.

[0035] By setting the collar 21, each adjacent holding plate 6 can be rotatably connected while leaving a certain gap to ensure the smooth rotation of the holding plate 6. At the same time, the existence of the gap ensures the thickness of the holding plate 6. By increasing the thickness, the impact of water splashes and ripples can be reduced when the gathering frame 1 is laid flat on the water surface. When the gathering frame 1 is gathered, the horizontal bar 19 tilts downward with the end near the float 2 as the pivot point, causing the inclined side of the holding plate 6 to tilt downward as a whole. At the same time, the collar 21 rotates outside the adjusting shaft 20, finally allowing the holding plate 6 to complete the angle adjustment and the gathering frame 1 to be gathered.

[0036] As the lifting sleeve 14 sinks, it drives the transmission arm 15 to move downward. At the same time, the two ends of the transmission arm 15 rotate adaptively, which in turn pulls the adjusting shaft 20 to move downward and simultaneously pulls the horizontal bar 19 to swing downward. Finally, under the adaptive rotation of the holding plate 6, the folding work is completed. When it needs to be unfolded, simply lift the lifting sleeve 14 to complete the opening work.

[0037] The electric rewinding reel rotates and pulls the cable 10, which in turn drags the lifting sleeve 14 downward, thereby achieving the retraction of the rewinding frame 1. When the electric rewinding frame releases the cable 10, the lifting sleeve 14, being hollow inside, will move upward under the action of buoyancy. At the same time, under the action of the floating roller 8, the edge of the holding plate 6 will also move upward, allowing the rewinding frame 1 to open automatically.

[0038] Once the holding plate 6 is submerged underwater, the water flow can clean dust and other stains from the surface of the waterproof membrane. Water can also be pumped in by the water pump 25 and sprayed outwards through the nozzles 22. The water flow passes through the gaps between the holding plates 6, acting on the water to create turbulence, effectively cleaning the outer surface. The elastic baffle 9 separates the sprayed water flow vertically, creating more complex turbulence, improving the cleaning effect and reducing impact loss. With this setup, the retractable frame 1 can be periodically lowered to clean the photovoltaic panel surface, and the water source is readily available, making it simpler and more convenient than traditional cleaning methods.

[0039] During operation, the connecting cable 5 is used to fix the adjacent top float 16, which can form a stable large-area photovoltaic area. The top float 16 is always above the water surface. Even if the support sinks, the connecting cable 5 will remain above the water surface, providing a stable fixing function. Finally, the end connecting cable 5 is fixed to the shore or pile to stabilize all the supports.

[0040] A vertical chain 3 is installed at the bottom of part of the center of gravity bladder 11 and fixed with a fixed anchor 4 to ensure the stability of the support. Often, it is only necessary to install it at the bottom of the support at the edge. It is necessary to ensure that the length of the vertical chain 3 is longer than the water depth so that the float 2 will not be affected when it moves up and down.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
