Description

Technical Field

[0001] This utility model relates to the field of photovoltaic inspection and maintenance technology, and in particular to a rooftop photovoltaic module that is easy to inspect and maintain. Background Technology

[0002] With the increasing global emphasis on renewable energy, rooftop distributed photovoltaic (PV) power generation systems have been widely promoted and applied due to their advantages such as efficient space utilization and reduced carbon emissions. However, ensuring the stable operation and efficient maintenance of the system during the actual operation of PV power plants has become an urgent problem to be solved.

[0003] During the long-term operation of photovoltaic panels, since they are exposed to the outdoors for extended periods, a large amount of dust may accumulate on their surface over time, which may reduce their power generation efficiency. In addition, each photovoltaic panel is fixed with bolts, requiring the use of bolt cutters and other tools for installation or disassembly, which is quite inconvenient.

[0004] To address the aforementioned issues, this utility model document proposes a rooftop photovoltaic module that is easy to inspect and maintain. Utility Model Content

[0005] This utility model provides a rooftop photovoltaic module that is easy to maintain, solving the problems of existing technology where, after the photovoltaic module is installed, the photovoltaic panel will be in operation for a long time. However, since the photovoltaic panel is exposed to the outdoors for a long time, a large amount of dust may accumulate on its surface, which may reduce its power generation efficiency. In addition, each photovoltaic panel is fixed with bolts, which requires the use of bolt cutters and other tools for installation or disassembly, making it inconvenient.

[0006] This utility model provides the following technical solution:

[0007] A rooftop photovoltaic module that is easy to maintain includes a support frame, a connecting plate fixedly connected to one side of the support frame, a left bracket and a right bracket fixedly connected to the top of the connecting plate respectively, a photovoltaic panel being arranged between the left bracket and the right bracket, and the same water storage box being fixedly connected to the top of the left bracket and the right bracket.

[0008] The cleaning mechanism is located on top of the photovoltaic panel and is used to clean the stains on its surface. The cleaning mechanism includes a first waterproof box, a first motor, a cleaning cylinder and a lifting mechanism. The top of the left and right supports are both provided with guide grooves, and guide blocks are slidably connected in both guide grooves. One side of the first waterproof box is fixedly connected to one side of one of the guide blocks. The bottom of the first motor is fixedly connected to the bottom inner wall of the first waterproof box. The output end of the first motor passes through one side of one of the guide blocks and is fixedly connected to one end of the cleaning cylinder. The other end of the cleaning cylinder is rotatably connected to one side of the other guide block.

[0009] The easy-to-install and remove mechanism is located on both sides of the photovoltaic panel for quick installation and removal.

[0010] In one possible design, the lifting mechanism includes a second waterproof box, a second motor, and a threaded screw. The bottom of the second waterproof box is fixedly connected to the top of the right bracket. The bottom of the second motor is fixedly connected to the inner wall of the bottom side of the second waterproof box. The output end of the second motor passes through one side of the second waterproof box and is fixedly connected to one end of the threaded screw. The other end of the threaded screw is rotatably connected to one side of the water storage box. The internal thread of another guide block is connected to the outer wall of the threaded screw.

[0011] In one possible design, multiple water nozzles are fixedly connected to one side of the water tank, and multiple brush bristles made of polyamide nylon are fixedly connected to the outer wall of the cleaning cylinder.

[0012] In one possible design, the easy-to-assemble / disassemble mechanism includes a locking ring, a slider, and a slide groove. The two sides of the support frame are fixedly connected to the sides of the left and right supports that are close to each other. Two slide grooves are respectively opened on the sides of the left and right supports that are close to each other. Two sliders are fixedly connected to the two sides of the photovoltaic panel and are slidably connected inside the two slide grooves. A through hole is opened on one side of the right support, and a locking hole is opened on one side of one of the sliders. A locking rod is fixedly connected to the outer wall of the locking ring. The other end of the locking rod passes through the inside of the through hole and is inserted into the inside of the locking hole. A locking plate is fixedly connected to one side of the right support. A plug is inserted into the inside of the locking ring. A limit hole is opened inside the locking plate. The other end of the plug passes through the inside of the locking ring and is inserted into the inside of the limit hole.

[0013] In one possible design, a pipeline groove is provided on one side of the left bracket, and a water inlet pipe is installed inside the pipeline groove. One end of the water inlet pipe is fixedly connected to one side of the water storage box.

[0014] In one possible design, mounting holes are provided at the bottom of the support frame and at the top of the connecting plate to facilitate the installation and fixation of the device.

[0015] In this application, during use, the support frame and connecting plate are first fixedly installed on the roof where installation is required. Then, the photovoltaic panel with two sliding strips is placed between the left and right supports, so that the two sliding strips are slidably connected in the grooves on the left and right supports respectively. The locking rod on the locking ring passes through the through hole on the right support and is inserted into the locking hole of the sliding strip on one side of the photovoltaic panel. Then, the insertion rod passes through the inside of the locking ring and is inserted into the limiting hole, thereby achieving rapid installation of the photovoltaic panel. When disassembly is required, first pull out the insertion rod to release the locking ring, then use the locking ring to remove the locking rod from the locking hole, and then slide the sliding strips on both sides of the photovoltaic panel to move it out of the groove, thereby removing the photovoltaic panel from between the left and right supports. Compared with traditional bolt connections, disassembly and assembly can be carried out without the use of screwdrivers or other tools, enabling the photovoltaic panel to be quickly and securely installed on the support. The cleaning mechanism works as follows: After a period of use, when the photovoltaic panel becomes covered with dust or bird droppings, the first and second motors are activated. The first motor drives the cleaning cylinder to rotate, and the bristles on the outer wall of the cleaning cylinder contact the surface of the photovoltaic panel, generating friction to clean the stains. The second motor drives the threaded screw to rotate. Since the threaded screw is internally connected to one of the guide blocks, the guide block moves along the axis of the threaded screw, thereby causing the cleaning cylinder to move back and forth above the photovoltaic panel for thorough cleaning. When a deeper cleaning is needed, water can be supplied to the water tank through the inlet pipe, and then the water tank sprays water out through the nozzle onto the surface of the photovoltaic panel. The cleaning cylinder and bristles work together with the water during rotation to further clean the stains on the surface of the photovoltaic panel. After cleaning is completed, the first and second motors are turned off to stop the movement of the cleaning mechanism.

[0016] In this utility model, a rooftop photovoltaic module that is easy to inspect and maintain can achieve the effect of quickly and stably installing photovoltaic panels on the bracket through a convenient disassembly and assembly mechanism. This not only improves installation efficiency but also facilitates subsequent maintenance or replacement work and reduces operation and maintenance costs.

[0017] In this utility model, a rooftop photovoltaic module that is easy to maintain can achieve a comprehensive and efficient cleaning effect on the surface of the photovoltaic panel through a cleaning mechanism, effectively preventing performance degradation and aging caused by long-term accumulation of dirt.

[0018] This invention enables rapid installation and disassembly of photovoltaic panels, efficient cleaning, and convenient inspection and maintenance. The convenient disassembly and assembly mechanism improves installation efficiency and flexibility, while the cleaning mechanism reduces cleaning costs and extends the service life of photovoltaic panels through automated cleaning.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0026] Please refer to Figure 1-4 A rooftop photovoltaic module includes: a support frame 1, a connecting plate fixedly connected to one side of the support frame 1, a left bracket 2 and a right bracket 4 fixedly connected to the top of the connecting plate respectively, a photovoltaic panel 3 disposed between the left bracket 2 and the right bracket 4, and a water storage box 8 fixedly connected to the top of the left bracket 2 and the right bracket 4. The bottom of the support frame 1 and the top of the connecting plate are provided with mounting holes to facilitate the installation and fixing of the device, thereby providing a foundation for the later use of the device.

[0027] A cleaning mechanism is installed on top of the photovoltaic panel 3 to clean stains on its surface. The cleaning mechanism includes a first waterproof box 10, a first motor 11, a cleaning cylinder 15, and a lifting mechanism. Guide grooves are provided on the tops of both the left support 2 and the right support 4, and guide blocks are slidably connected within each guide groove. One side of the first waterproof box 10 is fixedly connected to one side of one of the guide blocks. The bottom of the first motor 11 is fixedly connected to the inner wall of the bottom side of the first waterproof box 10. The output end of the first motor 11 passes through one side of one of the guide blocks and is fixedly connected to one end of the cleaning cylinder 15. The other end of the cleaning cylinder 15 is rotatably connected to one side of the other guide block. The lifting mechanism includes a second waterproof box 12, a second motor 13, and a threaded rod 14. The bottom of the second waterproof box 12 is fixedly connected to the top of the right support 4, and the bottom of the second motor 13 is fixedly connected to the bottom side of the second waterproof box 12. On the inner wall, the output end of the second motor 13 passes through one side of the second waterproof box 12 and is fixedly connected to one end of the threaded rod 14. The other end of the threaded rod 14 is rotatably connected to one side of the water storage box 8. The internal thread of another guide block is connected to the outer wall of the threaded rod 14. Thus, after the photovoltaic panel 3 has been used for a period of time, when dust or bird droppings or other stains adhere to its surface, the first motor 11 and the second motor 13 are started. The first motor 11 drives the cleaning cylinder 15 to rotate. The bristles 16 on the outer wall of the cleaning cylinder 15 contact the surface of the photovoltaic panel 3 and generate friction to clean the stains on the surface of the photovoltaic panel 3. The second motor 13 drives the threaded rod 14 to rotate. Since the threaded rod 14 is internally connected to one of the guide blocks, the guide block will move along the axial direction of the threaded rod 14, thereby driving the cleaning cylinder 15 to move back and forth above the photovoltaic panel 3 to achieve comprehensive cleaning.

[0028] A convenient installation and removal mechanism is located on both sides of the photovoltaic panel 3 for quick installation and removal. The mechanism includes a locking ring 5, sliding bars, and sliding grooves. The two sides of the support frame 1 are fixedly connected to the sides of the left support 2 and right support 4 that are close to each other. Two sliding grooves are respectively opened on the sides of the left support 2 and right support 4 that are close to each other. Two sliding bars are fixedly connected to both sides of the photovoltaic panel 3 and slidably connected inside the two sliding grooves. A through hole is opened on one side of the right support 4, and a locking hole is opened on one side of one of the sliding bars. A locking rod 501 is fixedly connected to the outer wall of the locking ring 5. The other end of the locking rod 501 passes through the through hole and is inserted into the locking hole. A locking plate is fixedly connected to one side of the right support 4. The locking ring 5... An insert rod 502 is inserted internally. A limiting hole is opened inside the locking plate. The other end of the insert rod 502 passes through the inside of the locking ring 5 and is inserted into the limiting hole. This allows the photovoltaic panel 3 with two sliders to be placed between the left bracket 2 and the right bracket 4. The two sliders are slidably connected in the grooves on the left bracket 2 and the right bracket 4, respectively. The locking rod on the locking ring passes through the through hole on the right bracket and is inserted into the locking hole of the slider on one side of the photovoltaic panel. Then the insert rod passes through the inside of the locking ring and is inserted into the limiting hole. Compared with the traditional bolt connection, it can be disassembled and assembled without the use of screwdrivers or other tools. It can achieve the effect of quickly and stably installing the photovoltaic panel on the bracket, thus realizing the rapid installation of the photovoltaic panel.
