Description

Technical Field

[0001] This utility model relates to the field of solar photovoltaic power generation auxiliary equipment technology, and in particular to an intelligent distributed photovoltaic module cleaning device. Background Technology

[0002] With the increasing global demand for clean energy, photovoltaic power generation, as a sustainable and pollution-free energy source, has been widely adopted. Distributed photovoltaic power generation systems, due to their flexibility in installation on building rooftops, industrial and commercial plants, and other locations, can effectively utilize idle space and reduce power transmission losses, and have seen particularly rapid development in recent years.

[0003] In distributed photovoltaic (PV) power generation systems, PV modules are the core components, and their power generation efficiency directly affects the performance of the entire system. However, in actual use, PV modules are exposed to the outdoor environment for extended periods, making them highly susceptible to contamination from dust, dirt, bird droppings, leaves, and other impurities. The accumulation of these contaminants on the surface of the PV modules blocks sunlight, reducing the modules' efficiency in absorbing and converting sunlight, and consequently leading to a significant decrease in power generation.

[0004] Currently, the cleaning of photovoltaic modules is mainly done manually, requiring the addition of auxiliary cleaning tools and cannot be fully automated. Manual cleaning relies on handheld cleaning tools, which is not only inefficient and labor-intensive, but also consumes significant manpower and time when cleaning large-scale distributed photovoltaic power stations. Furthermore, the inconsistent pressure and methods used by operators during manual cleaning can easily scratch and damage the surface of the photovoltaic modules, affecting their lifespan. Utility Model Content

[0005] To overcome the aforementioned shortcomings, the technical problem is to provide an intelligent distributed photovoltaic module cleaning device.

[0006] The technical solution is as follows: An intelligent distributed photovoltaic module cleaning device includes a support frame, a photovoltaic module body, an electric slide rail, a slider, a connecting frame, a rack, a drive gear, a driven gear, and a rotating brush. The support frame adopts an inclined structure design, and the photovoltaic module body is installed on the inclined part. Electric slide rails are symmetrically connected to the front and back of the top of the photovoltaic module body. Sliders are slidably connected to each electric slide rail. The electric slide rails are electrically connected to a remote control system. Connecting frames are connected to each slider. Racks are connected to the front and back side walls of the lower side of the photovoltaic module body. The drive gear and driven gear are respectively connected to the lower side of the connecting frame through two rotating shafts. The drive gear is located below and the driven gear is located above. The drive gear and driven gear mesh with each other. At the same time, the drive gear meshes with the rack. A rotating brush is slidably connected to the left side of the photovoltaic module body. The front and rear ends of the rotating brush are respectively connected to the rotating shaft connected to the driven gear, and the rotating brush is in close contact with the top surface of the photovoltaic module body.

[0007] Furthermore, it also includes a first water spray pipe, a second water spray pipe, and high-pressure nozzles. The first water spray pipe and the second water spray pipe are connected between the upper sides of the two connecting frames, with the first water spray pipe located on the left and the second water spray pipe located on the right. The middle of the two is connected by a rigid pipe. Multiple high-pressure nozzles are installed at intervals at the bottom of both the first water spray pipe and the second water spray pipe.

[0008] Furthermore, it also includes a telescopic hose, a first water pump, and a water storage tank. The top of the rigid pipe between the first water spray pipe and the second water spray pipe is connected to and connected to the telescopic hose. The top left side of the bracket is connected to the water storage tank. The top of the water storage tank is equipped with the first water pump. The bottom pipe of the first water pump penetrates into the interior of the water storage tank, and its top pipe is connected to the telescopic hose. The first water pump is electrically connected to the remote control system.

[0009] Furthermore, it also includes a collection box and a filter frame. The collection box is installed on the far right side of the bracket. The collection box is located at the lower right corner of the photovoltaic module body. The filter frame is connected to the upper inner side of the collection box by a pull-out mechanism.

[0010] Furthermore, a handle is attached to the right side of the filter frame.

[0011] Furthermore, it also includes a connecting pipe and a second water pump. A connecting pipe is connected between the front side of the water storage tank and the front side of the filter frame. A second water pump is installed at the right end of the connecting pipe and is electrically connected to the remote control system.

[0012] The beneficial effects are as follows: 1. The device is equipped with a remotely operated electric slide rail and a first water pump, which can automatically complete the spraying of cleaning water and the brushing of component surfaces without the need for frequent manual operation, greatly saving manpower and improving cleaning efficiency.

[0013] 2. The process involves first pre-rinsing with high-pressure spray nozzles to disperse dust and impurities, and then scrubbing with rotating brushes to deeply clean the surface of the components, effectively ensuring photovoltaic power generation efficiency.

[0014] 3. The collection box and filter frame collect the cleaning water. After the filter frame removes impurities, the second water pump pumps the water back to the storage tank for recycling, which greatly improves the water resource utilization rate and reduces cleaning costs.

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0021] Example: A smart distributed photovoltaic module cleaning device, such as Figures 1-4As shown, the system includes a support 1, a photovoltaic module body 2, an electric slide rail 3, a slider 4, a connecting frame 5, a rack 12, a drive gear 13, a driven gear 14, and a rotating brush 15. The support 1 adopts an inclined structure design, and the photovoltaic module body 2 is installed on the inclined part to ensure that the photovoltaic module body 2 receives solar radiation to the maximum extent and improves photovoltaic power generation efficiency. The top front and rear front of the photovoltaic module body 2 are symmetrically connected to the electric slide rail 3, and the slider 4 is slidably connected to each of the electric slide rail 3. The electric slide rail 3 is electrically connected to the remote control system. The slider 4 is connected to the connecting frame 5. The front and rear side walls of the lower side of the photovoltaic module body 2 are welded with racks 12. The lower side of the connecting frame 5 is connected to the drive gear 13 and the driven gear 14 via two rotating shafts. Driven gear 14 and driving gear 13 are located below and driven gear 14 is located above. Driven gear 13 and driven gear 14 mesh with each other. Driven gear 13 has more teeth than driven gear 14. Driven gear 13 meshes with rack 12. When connecting frame 5 moves under the drive of electric slide rail 3, drive gear 13 rotates under the action of rack 12, and then drives driven gear 14 to rotate through meshing. A rotating brush 15 is slidably connected to the left side of photovoltaic module body 2. The front and rear ends of rotating brush 15 are respectively connected to the rotating shaft connected to driven gear 14. Rotating brush 15 is in close contact with the top surface of photovoltaic module body 2, thereby cleaning the top surface of photovoltaic module body 2.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a first water spray pipe 6, a second water spray pipe 7, high-pressure nozzles 8, a telescopic hose 9, a first water pump 10, and a water storage tank 11. The first water spray pipe 6 and the second water spray pipe 7 are connected between the upper sides of the two connecting frames 5, with the first water spray pipe 6 located on the left and the second water spray pipe 7 located on the right. The middle of the two is connected by a rigid pipe. Multiple high-pressure nozzles 8 are installed at intervals at the bottom of the first water spray pipe 6 and the second water spray pipe 7. These high-pressure nozzles 8 are all oriented towards the top surface of the photovoltaic module body 2. The high-pressure nozzles 8 can spray clean water at high pressure. The water is sprayed onto the surface of the photovoltaic module body 2 in the form of pressure jet to achieve rinsing of the surface of the photovoltaic module body 2. The top of the rigid pipe between the first water spray pipe 6 and the second water spray pipe 7 is connected and connected to the telescopic hose 9. The top left side of the bracket 1 is connected to the water storage tank 11 by bolts. The top of the water storage tank 11 is equipped with a first water pump 10. The bottom pipe of the first water pump 10 penetrates into the interior of the water storage tank 11 to draw clean water from the water storage tank 11. Its top pipe is connected to the telescopic hose 9. The first water pump 10 is electrically connected to the remote control system.

[0023] After the photovoltaic module body 2 is installed at a designated location via the bracket 1 and has been used for a long time, dust and impurities easily accumulate on its surface, affecting the photovoltaic power generation efficiency. Therefore, cleaning is necessary. Before cleaning, sufficient cleaning water must be stored in the water tank 11. During cleaning, the operator starts the first water pump 10 via the remote control system. The first water pump 10 draws out the cleaning water from the water tank 11. The cleaning water enters the telescopic hose 9 through the pipe at the top of the first water pump 10, then enters the first spray pipe 6 and the second spray pipe 7, and finally is sprayed from the high-pressure nozzle 8 onto the surface of the photovoltaic module body 2. The cleaning water sprayed from the high-pressure nozzle 8 pre-rinses the surface of the photovoltaic module body 2, initially removing dust and impurities. After pre-rinsing, the electric slide rail 3 is activated. The electric slide rail 3 drives the slider 4, the connecting frame 5, and the first and second spray pipes 6 and 7 on the connecting frame 5 to move downwards and to the right. As the connecting frame 5 moves, the drive gear 13 begins to rotate under the action of the rack 12. Since the driving gear 13 and driven gear 14 mesh with each other, and the driving gear 13 has more teeth than the driven gear 14, according to the gear transmission principle, the rotation of the driving gear 13 drives the driven gear 14 to rotate at high speed. The rotation of the driven gear 14 drives the rotating brush 15 to rotate synchronously through the rotating shaft. At this time, as the rotating brush 15 moves to the lower right, it thoroughly brushes the surface of the photovoltaic module body 2, further removing residual dirt from the surface. The high-pressure nozzle 8 can spray cleaning water synchronously. After cleaning is completed, the electric slide rail 3 drives the slider 4 and the connecting frame 5 to move to the upper left to reset. The first water spray pipe 6, the second water spray pipe 7, the driving gear 13, the driven gear 14, the rotating brush 15 and other components on the connecting frame 5 also reset accordingly. After the reset is completed, the electric slide rail 3 and the first water pump 10 are turned off, completing a complete cleaning operation.

[0024] like Figure 1 As shown, the system also includes a collection box 16, a filter frame 17, a connecting pipe 18, and a second water pump 19. The collection box 16 is bolted to the far right of the bracket 1. The collection box 16 is located at the lower right corner of the photovoltaic module body 2. During the cleaning process, the water used will flow into the collection box 16 located on the far right of the bracket 1 under the action of gravity. The filter frame 17 is connected to the upper inner side of the collection box 16 by a pull-out type. The filter frame 17 is used to filter impurities in the water used and is easy to pull out and clean later. A handle is connected to the right side of the filter frame 17 to facilitate the removal of the filter frame 17 from the collection box 16. A connecting pipe 18 is connected between the front side of the water storage tank 11 and the front side of the filter frame 17. The second water pump 19 is installed at the right end of the connecting pipe 18. The second water pump 19 is electrically connected to the remote control system. After the second water pump 19 is started, the filtered water in the filter frame 17 can be pumped back to the water storage tank 11 through the connecting pipe 18, thereby realizing the reuse of clean water source, improving the utilization efficiency of water resources, and reducing cleaning costs.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
