Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, specifically a foldable, mobile photovoltaic module. Background Technology

[0002] Solar photovoltaic (PV) cells are used to directly convert solar energy into electrical energy. A photovoltaic module is a set of PV cells that, according to application requirements, are combined to achieve a certain rated output power and voltage. PV is short for solar photovoltaic power generation system, a new type of power generation system that utilizes the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has two modes: stand-alone operation and grid-connected operation. PV is defined as the direct conversion of radiation energy; in practical applications, it usually refers to the conversion of solar energy into electrical energy, i.e., solar photovoltaic. Its implementation mainly involves using solar panels made of semiconductor materials such as silicon to generate direct current (DC) using sunlight. A photovoltaic module is one such example.

[0003] Existing photovoltaic (PV) modules have a traditional structure and limited functionality. When their location needs to be changed, workers must handle them with heavy lifting, which is time-consuming and labor-intensive. This also increases the risk of damage, such as bumps and knocks, leading to significant economic losses. Furthermore, existing PV modules require thorough cleaning of their surfaces before each use. Failure to do so can result in accumulated dust that reduces panel efficiency, increases internal temperature, and severely impacts power generation. It can even cause hot spots on the solar cells.

[0004] To address these issues, the present invention provides a foldable, mobile photovoltaic module. Summary of the Invention

[0013] Preferably, a limiting plate is fixedly provided at the end of both the first toothed plate and the second toothed plate. Beneficial effects

[0014] This invention provides a foldable, portable photovoltaic module. Compared with existing technologies, it has the following advantages: (1) The foldable mobile photovoltaic module, through the cooperation of rotating components, tensioning wheels and tension springs, allows the two crossbeams to be pulled together under the action of the tension spring when the tensioning wheels are not installed. Since the side walls of the crossbeams are flat, the rotation of the photovoltaic panel is effectively prevented. When the tensioning wheels are installed, the two crossbeams can be separated and the photovoltaic module can be unfolded by rotating the limiting block in the limiting slot. The operation is simple and quick, and it can effectively prevent the upper end of the photovoltaic module from opening when the folded photovoltaic module is moved, ensuring the safety of the movement and transportation. At the same time, the photovoltaic module can be unfolded with great effort when in use.

[0015] (2) The foldable mobile photovoltaic module, through the cooperation of the moving auxiliary component, the tensioning wheel and the moving block, etc., makes the moving slot on the side wall of the tensioning wheel and the moving block on the side wall of the crossbeam engage with each other. When the moving block enters the moving slot, it drives the lower end of the auxiliary wheel and the lower end of the tensioning wheel to be on the same horizontal plane. Thus, while the photovoltaic module moves under the action of the tensioning wheel, the two auxiliary wheels can effectively support its movement, prevent the photovoltaic panel from tipping over, facilitate the movement of the photovoltaic module, and provide good protection during the movement of the photovoltaic module.

[0016] (3) The foldable mobile photovoltaic module, through the cooperation of the transmission component, the sliding plate and the first cleaning plate, enables the first cleaning plate to move on the surface of the protective plate. When cleaning the protective plate, it drives the second cleaning plate to move, thereby realizing the simultaneous relative movement of the first and second cleaning plates, and thus thoroughly cleaning the protective plate. It maintains the synchronization of the first and second cleaning plates and ensures an efficient cleaning process for the protective plate.

[0017] (4) The foldable mobile photovoltaic module, through the cooperation of the squeeze drainage module, two cleaning plates and water tank, etc., causes the first cleaning plate and the second cleaning plate to move in the drainage channel when they move, thereby increasing the water pressure in the water tank. When the water pressure reaches a certain level, the dust and garbage on the surface of the protective plate are impacted and cleaned. When the pressure plate slides to the lower end of the drainage channel, the elastic telescopic rod retracts, so that when the photovoltaic panel is working, the first cleaning plate and the second cleaning plate are in the water tank, preventing adverse effects on the normal operation of the photovoltaic panel.

[0018] (5) The foldable mobile photovoltaic module, through the cooperation of multiple components, allows the two cleaning plates to move and clean the protective plate surface by sliding the sliding plate when the photovoltaic module is unfolded. No manual cleaning is required, saving labor. At the same time, the water in the water tank can be automatically discharged during the cleaning process. With the movement of the cleaning plates, the surface of the photovoltaic module is effectively cleaned efficiently and thoroughly, saving time and effort and improving work efficiency.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0021] Please see Figure 1-7A foldable, mobile photovoltaic module includes four photovoltaic panels 1, arranged in pairs. A water tank 4 is fixed between two photovoltaic panels 1 on the same plane. A crossbeam 2 is fixed at the end of each photovoltaic panel 1 away from the water tank 4. A support frame 3 is fixed between two crossbeams 2 on the same plane. The support frame 3 is located on the side walls of the photovoltaic panels 1. Multiple cavities 6 are recessed on the upper walls of the two adjacent upper crossbeams 2. A tension spring 7 is connected between two adjacent cavities 6. Corresponding rotating components are provided on the side walls of the crossbeams 2. Movable blocks 13 are fixed on the side walls of the two adjacent lower crossbeams 2. The two movable blocks 13 together form a cylindrical shape. Corresponding tensioning wheels 19 are provided on the side walls of the crossbeams 2. A movable slot 22 is recessed on one side wall of the tensioning wheel 19. The movable slot 22 and the movable block 13 interlock. Next, the two side walls of the movable card block 13 are also provided with movable auxiliary components. A support rod 8 is rotatably provided on one side wall of the support frame 3, and a limiting rod 9 is rotatably provided on the side wall of the support rod 8. A sliding cavity 10 is provided in the side wall of the support frame 3, and a sliding plate 11 is slidably provided in the sliding cavity 10. The limiting rod 9 and the sliding plate 11 are rotatably connected. The two ends of the surface of the protective plate 5 are respectively provided with a first cleaning plate 23 and a second cleaning plate 24. The first cleaning plate 23 and the sliding plate 11 are connected to each other. A transmission component is provided in the side wall of the support frame 3. The first cleaning plate 23 and the second cleaning plate 24 are connected by the transmission component. A squeezing drainage component is also provided between the first cleaning plate 23, the second cleaning plate 24 and the water tank 4. When it is necessary to move the device, the movable card slot 22 on the side wall of the tensioning wheel 19 and the movable card block 13 can be engaged with each other. Thus, when moving the photovoltaic module, the rotation of the tensioning wheel 19 can facilitate the movement of the photovoltaic module. Example

[0022] Please see Figure 1-7This embodiment provides a technical solution based on Embodiment 1: The rotating assembly includes a stop block 21 fixedly disposed on the side wall of the tensioning wheel 19, a limiting block 12 fixedly disposed on the side wall of the upper crossbeam 2, two limiting grooves 20 recessed on the side wall of the tensioning wheel 19, the limiting grooves 20 and the limiting block 12 matching each other, the limiting grooves 20 and the movable grooves 22 respectively disposed on the two side walls of the tensioning wheel 19, and rubber snap rings fixedly disposed at the end side walls of the limiting block 12 and the movable block 13, so that when the tensioning wheel 19 is connected to the limiting block 12 and the movable block 13, it effectively prevents them from sliding out of the tensioning wheel 19. The cross-section of the stop block 21 is triangular, and the stop block 21 and the tensioning wheel 19 are integrally formed, so that the stop block 21 can hold the two limiting blocks 12. The two crossbeams 2 are separated by the squeezing mechanism, which allows the limiting block 12 to slide into the limiting slot 20, thus facilitating the unfolding of the photovoltaic module. Through the cooperation of the rotating component, the tensioning wheel 19, and the tension spring 7, the two crossbeams 2 are pulled together by the tension spring 7 when the tensioning wheel 19 is not installed. Since the side walls of the crossbeams 2 are flat, the rotation of the photovoltaic panel 1 is effectively prevented. When the tensioning wheel 19 is installed, the two crossbeams 2 can be separated, and the photovoltaic module can be unfolded by the rotation of the limiting block 12 in the limiting slot 20. The operation is simple and quick, and it can effectively prevent the upper part of the photovoltaic module from opening when the folded photovoltaic module is moved, ensuring the safety of the movement and transportation. At the same time, the photovoltaic module can be unfolded with great effort when in use. The moving auxiliary component includes a sliding block 14 slidably mounted on the side wall of the crossbeam frame 2. A lever 15 is fixedly mounted on the side wall of the sliding block 14. A spring cavity 17 is provided inside the side wall of the crossbeam frame 2. A return spring 18 is fixedly mounted inside the spring cavity 17. An auxiliary wheel 16 is provided on the outer side wall of the crossbeam frame 2. The auxiliary wheel 16 and the return spring 18 are fixedly connected. The lever 15 and the side wall of the auxiliary wheel 16 are in contact with each other. Through the cooperation of the moving auxiliary component, the tensioning wheel 19 and the moving block 13, the moving slot 22 on the side wall of the tensioning wheel 19 and the moving block 13 on the side wall of the crossbeam frame 2 are engaged with each other. When the moving block 13 enters the moving slot 22, it drives the lower end of the auxiliary wheel 16 and the lower end of the tensioning wheel 19 to be on the same horizontal plane. Thus, while the photovoltaic module moves under the action of the tensioning wheel 19, the two auxiliary wheels 16 can effectively support its movement, prevent the photovoltaic panel 1 from tipping over, facilitate the movement of the photovoltaic module, and provide good protection during the movement of the photovoltaic module. The transmission assembly includes a transmission cavity 28 disposed within the side wall of the support frame 3. A gear rod 29 is rotatably mounted on the middle inner wall of the transmission cavity 28. A gear 30 is fixedly mounted on the side wall of the gear rod 29. A first toothed plate 31 and a second toothed plate 32 are slidably mounted on the upper and lower side walls of the transmission cavity 28. The first toothed plate 31 and the second toothed plate 32 are symmetrical about the center of the gear 30. The first toothed plate 31 is fixedly connected to the slide plate 11, and the second toothed plate 32 is fixedly connected to the second cleaning plate 24. A limiting plate 33 is fixedly mounted at the end of both the first toothed plate 31 and the second toothed plate 32. The movement paths of the toothed plate 31 and the second toothed plate 32 are restricted to prevent deflection or tilting. Through the cooperation of the transmission assembly, the slide plate 11 and the first cleaning plate 23, the first cleaning plate 23 moves on the surface of the protective plate 5. When cleaning the protective plate 5, it drives the second cleaning plate 24 to move, thereby realizing that the first cleaning plate 23 and the second cleaning plate 24 move relative to each other at the same time, thus thoroughly cleaning the protective plate 5. The synchronization of the first cleaning plate 23 and the second cleaning plate 24 is maintained, ensuring an efficient cleaning process for the protective plate 5. The squeeze drainage assembly includes drainage channels located on both sides of the water storage tank 4. Pressure plates 26 are slidably sealed within the drainage channels. Elastic telescopic rods 25 are fixed between the two pressure plates 26 and the first cleaning plate 23 and the second cleaning plate 24, respectively. Multiple water outlets 27 are evenly distributed on the side walls of the water storage tank 4, all facing the surface of the protective plate 5. Each water outlet 27 is equipped with a pressure relief valve. Through the coordinated operation of the squeeze drainage assembly, the two cleaning plates, and the water storage tank 4, the movement of the first cleaning plate 23 and the second cleaning plate 24 causes the pressure plates 26 to move within the drainage channels, thereby increasing the water pressure within the water storage tank 4. When the water pressure reaches a certain level, it impacts and cleans dust and debris from the surface of the protective plate 5. When the pressure plates 26 slide to the lower end of the drainage channels, the elastic telescopic rods 25 retract, ensuring that the first cleaning plates 23 and the second cleaning plates 24 are positioned within the water storage tank 4 during operation of the photovoltaic panel 1, preventing any adverse effects on the normal operation of the photovoltaic panel 1.

[0023] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0024] When the photovoltaic module is retracted: the slide plate 11 slides to the top of the sliding cavity 10, causing the support rod 8 and the limiting rod 9 to retract to both sides of the support frame 3. At this time, the movable slot 22 on the side wall of the tightening wheel 19 and the movable block 13 on the side wall of the crossbeam frame 2 are engaged with each other. As the movable block 13 enters the movable slot 22, it pushes the sliding block 14 to move to both sides, thereby driving the lever 15 to push the auxiliary wheel 16, which stretches the return spring 18 and moves the auxiliary wheel 16 downward until the lower end of the auxiliary wheel 16 and the lower end of the tightening wheel 19 are on the same horizontal plane. Since the end side wall of the lever 15 is smooth, the operator can push the photovoltaic module, causing the auxiliary wheel 16 and the tightening wheel 19 to rotate together, thereby enabling the device to move.

[0025] When using the photovoltaic module: remove the tensioning wheel 19 from the moving block 13, align the abutment 21 between the two limiting blocks 12 and push it downwards, causing the two limiting blocks 12 to move away from each other and slide into the limiting slot 20. Then, the photovoltaic panel 1 can be unfolded by rotating the support frame 3. When unfolding the photovoltaic panel 1, the support rod 8 can be rotated simultaneously, causing the limiting rod 9 to rotate, which drives the sliding plate 11 to slide in the sliding cavity 10, thereby driving the first cleaning plate 23 to move on the surface of the protective plate 5 to clean the protective plate 5. At the same time, when the sliding plate 11 moves, it can drive the first toothed plate 31 to move, and the gear 30 rotates accordingly, driving the second toothed plate 32 to move. When the first cleaning plate 23 moves, it drives the second cleaning plate 24 to move, thereby enabling the first cleaning plate 23 and the second cleaning plate 24 to move relative to each other simultaneously, thus thoroughly cleaning the protective plate 5. At the same time, when the first cleaning plate 23 and the second cleaning plate 24 move, they drive the pressure plate 26 to move in the drainage channel, thereby increasing the water pressure in the water storage tank 4. When the water pressure reaches a certain level, it impacts and cleans the dust and debris on the surface of the protective plate 5. When the pressure plate 26 slides to the lower end of the drainage channel, the elastic telescopic rod 25 retracts, so that when the photovoltaic panel 1 is working, the first cleaning plate 23 and the second cleaning plate 24 are located in the water storage tank 4, preventing adverse effects on the normal operation of the photovoltaic panel 1.
