Description

Technical Field

[0002] In the field of photovoltaic power generation, the cleaning of photovoltaic panels is crucial to maintaining the efficiency and life of the photovoltaic system. However, existing photovoltaic panel surface cleaning devices have some problems in terms of cleaning effect, connection efficiency and cleaning difficulty, which affect the performance and reliability of the photovoltaic system. First, photovoltaic panels are used for a long time and are in an outdoor environment. The surface is easily contaminated with dust and foreign matter. These dust and foreign matter may reduce the transmittance of the photovoltaic panels and reduce the absorption of light energy, thereby affecting the power generation efficiency of the photovoltaic panels. In addition, dust and foreign matter may also cause the surface temperature of the photovoltaic panels to rise, further reducing the performance of the photovoltaic panels.

[0003] Secondly, in existing devices, the connection operation between the nozzle and the delivery pipe is usually cumbersome, and quick connection and quick disassembly cannot be achieved. This connection method not only increases the difficulty of operation, but may also affect the use efficiency of the cleaning device. In addition, the sealing of the pipeline connection is poor, which can easily lead to water seepage, thereby affecting the normal operation of the cleaning device.

[0004] In addition, photovoltaic panels may be contaminated with highly adhesive foreign matter, such as bird droppings, which are difficult to clean and cannot be cleaned with a simple cleaning roller. Adhesive foreign matter not only affects the appearance of the photovoltaic panels, but may also cause local shadows on the surface of the photovoltaic panels, affecting the power generation efficiency of the photovoltaic panels.

[0031] A driving assembly 12 is disposed in the mounting frame 1 , and output ends of the driving assembly 12 are connected to the transmission shaft 5 and the cleaning roller 2 respectively.

[0032] A guide wheel 13 is provided below the mounting frame 1 , and the guide wheel 13 is symmetrically installed below the mounting frame 1 .

[0033] The plug-in mechanism includes a plug-in frame 14 and a plug-in slot 15 . The plug-in slot 15 is arranged outside the insertion tube 6 . One end of the plug-in frame 14 is connected to the reducing block 9 , and the other end of the plug-in frame 14 is engaged in the plug-in slot 15 .

[0034] A rubber ring 16 is disposed on the outer side of the insertion tube 6 , a sealing groove 17 is correspondingly formed on the inner side of the connecting tube 8 , and the rubber ring 16 is engaged in the corresponding sealing groove 17 .

[0035] In this embodiment, when it is necessary to clean the surface of the photovoltaic panel, the mounting frame 1 is reasonably placed on the surface of the photovoltaic panel so that the moving wheel 4 contacts the top surface of the photovoltaic panel and the guide wheels 13 contact the two sides of the photovoltaic panel, so that the movement of the mounting frame 1 is more stable, and then the rotating sleeve 7 is rotated in the corresponding direction, and the rotating sleeve 7 will drive the reducing groove 10 to move. Due to the special structural design of the reducing groove 10 and the reducing block 9, when the rotating sleeve 7 rotates, the reducing groove 10 will drive the reducing block 9 to move relatively outward, and then the reducing block 9 will drive the plug-in frame 14 to move outward. When the rotating sleeve 7 cannot continue to rotate, the reducing block 9 stops moving, and one end of the plug-in frame 14 is flush with the inner wall of the connecting pipe 8.

Then the conveying equipment is turned on, so that the conveying equipment conveys clean water to the nozzle 3 through the connecting pipe 8, and then sprays it to the surface of the photovoltaic panel through the nozzle 3. Then the drive assembly 12 installed on one side of the mounting frame 1 is turned on. The drive assembly 12 will drive the cleaning roller 2 to rotate to complete the cleaning of the photovoltaic panel surface. At the same time, the drive assembly 12 will drive the moving wheel 4 to rotate through the transmission shaft 5, so that the mounting frame 1 as a whole moves on the surface of the photovoltaic panel, and at the same time, the guide wheel 13 will move on the side wall of the photovoltaic panel, thereby realizing comprehensive and automatic cleaning of the photovoltaic panel.

[0036] See also Figure 2 and Figure 3 As an implementation method of a photovoltaic panel surface cleaning device for a scraping device: the scraping device includes a scraper 18 and a limiting frame 19, the limiting frame 19 is symmetrically arranged on both sides of the cleaning roller 2, and the scraper 18 is arranged below the limiting frame 19.

[0038] A push spring 21 is provided at the top of the limiting plate 20 , and the push spring 21 is movably installed in the limiting plate 20 .

[0039] More specifically, when the mounting frame 1 moves as a whole, the water sprayed from the nozzle 3 will slightly soften the bird droppings or dirt adhered to the surface of the photovoltaic panel, and then the scraper 18 will contact the top surface of the photovoltaic panel and scrape off the bird droppings or dirt adhered to the surface of the photovoltaic panel. When the scraper 18 touches the protrusion on the surface of the photovoltaic panel, the scraper 18 will drive the limit plate 20 to move, so that the limit plate 20 moves up in the limit frame 19, and then the limit plate 20 will compress the push spring 21 set on the inner side of the limit frame 19. After passing over the protrusion, the push spring 21 will automatically reset and drive the limit plate 20 and the scraper 18 to reset, and then continue to clean the surface of the photovoltaic panel.

[0040] In summary, when the overall equipment is in use or running: when the surface of the photovoltaic panel needs to be cleaned, the mounting frame 1 is reasonably placed on the surface of the photovoltaic panel, so that the moving wheel 4 contacts the top surface of the photovoltaic panel, and the guide wheels 13 contact the two sides of the photovoltaic panel, so that the movement of the mounting frame 1 is more stable, and then the rotating sleeve 7 is rotated in the corresponding direction, and the rotating sleeve 7 will drive the reducing groove 10 to move. Due to the special structural design of the reducing groove 10 and the reducing block 9, when the rotating sleeve 7 rotates, the reducing groove 10 will drive the reducing block 9 to move relatively outward, and then the reducing block 9 will drive the plug-in frame 14 to move outward. When the rotating sleeve 7 cannot continue to rotate, the reducing block 9 stops moving, and one end of the plug-in frame 14 is flush with the inner wall of the connecting pipe 8. Then, the insertion tube 6 connected to the external conveying equipment is inserted into the connecting pipe 8, and one end of the insertion tube 6 is against the rubber ring 11 set on the inner side of the connecting pipe 8, and then the rotating sleeve 7 is rotated in the opposite direction so that the reducing groove 10 The reducer 9 is driven to reset, and one end of the plug-in frame 14 is inserted into the plug-in slot 15. Due to the unique slope design in the plug-in slot 15, when the plug-in frame 14 is fully inserted into the plug-in slot 15, the insertion tube 6 will be slightly pressed down, so that one end of the plug-in tube presses the rubber ring 11, and the rubber rings 16 arranged on the outside of the insertion tube 6 are all engaged in the corresponding sealing groove 17, effectively ensuring the high sealing of the connection. Then the conveying equipment is turned on, so that the conveying equipment conveys clean water to the nozzle 3 through the connecting pipe 8, and then sprays it to the surface of the photovoltaic panel through the nozzle 3. Then the driving assembly 12 installed on one side of the mounting frame 1 is turned on. The driving assembly 12 will drive the cleaning roller 2 to rotate to complete the cleaning of the photovoltaic panel surface. At the same time, the driving assembly 12 will drive the moving wheel 4 to rotate through the transmission shaft 5, so that the mounting frame 1 as a whole moves on the surface of the photovoltaic panel, and at the same time, the guide wheel 13 will move on the side wall of the photovoltaic panel, thereby realizing comprehensive and automatic cleaning of the photovoltaic panel.

[0041] When the mounting frame 1 moves as a whole, the water sprayed from the nozzle 3 will slightly soften the bird droppings or dirt adhered to the surface of the photovoltaic panel, and then the scraper 18 will contact the top surface of the photovoltaic panel and scrape off the bird droppings or dirt adhered to the surface of the photovoltaic panel. When the scraper 18 touches the protrusion on the surface of the photovoltaic panel, the scraper 18 will drive the limit plate 20 to move, so that the limit plate 20 moves up in the limit frame 19, and then the limit plate 20 will compress the push spring 21 set on the inner side of the limit frame 19. After passing over the protrusion, the push spring 21 will automatically reset and drive the limit plate 20 and the scraper 18 to reset, and then continue to clean the surface of the photovoltaic panel.
