[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment 1 See also Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Fig. 9 and Fig.10 The present invention provides a photovoltaic glass panel cleaning device, comprising a shell 1, on which a walking mechanism 2, a cleaning mechanism 3 and a spraying mechanism 4 are installed. The walking mechanism 2 is used to make the shell 1 move linearly on the photovoltaic glass panel, and the shell 1 does not tilt during the movement. The cleaning mechanism 3 includes a roller brush 31, which is installed inside the shell 1 and is used to clean dust accumulated on the photovoltaic glass panel. The spraying mechanism 4 includes a nozzle 41, a scraper 42, a movable mounting seat 43 and a translation drive assembly 44. The nozzle 41 is used to spray water and coating liquid, and the scraper 42 is used to scrape off cracked and damaged coating on the surface of the photovoltaic glass panel. The nozzle 41 and the scraper 42 are both installed on the movable mounting seat 43, and the translation drive assembly 44 is used to drive the movable mounting seat 43 to move in a linear direction. An adjustment mechanism 5 is provided on the movable mounting seat 43, and the adjustment mechanism 5 includes a rotation adjustment component 51 and a telescopic adjustment component 52. The rotation adjustment component 51 is used to control the rotation of the scraper 42, so that the scraper 42 can be tilted toward the direction of the movable mounting seat 43 when the movable mounting seat 43 moves, so as to facilitate scraping off the coating layer on the photovoltaic glass panel. The telescopic adjustment component 52 is used to control the extension and retraction of the scraper 42, so that the scraper 42 will not be hindered by the photovoltaic glass panel when rotating.

[0023] As can be seen from the above, since the nozzle 41 can not only be used to spray water in conjunction with the roller brush 31 to improve the cleaning effect, but can also be used to spray the coating liquid, by setting the rotation adjustment component 51 and the telescopic adjustment component 52, on the one hand, the distance between the scraper 42 and the photovoltaic glass panel can be adjusted, so that the scraper 42 will not excessively damage the coating layer when scraping bird droppings stuck on the photovoltaic glass panel. On the other hand, the scraper 42 will not scratch the photovoltaic panel when changing its tilt direction. Therefore, when the moving direction of the movable mounting seat 43 changes, the scraper 42 can also change its tilt direction, so that the blade of the scraper 42 is always facing the moving direction of the movable mounting seat 43 , so that the scraper 42 can fully clean the photovoltaic glass panel to avoid omissions; when cleaning the photovoltaic glass panel, the roller brush 31 can clean the dust accumulated on the photovoltaic glass panel, the nozzle 41 is used to spray water on the photovoltaic glass panel, and the scraper 42 can scrape off the bird droppings stuck on the photovoltaic glass panel, thereby improving the cleaning effect on the surface of the photovoltaic glass panel. When the photovoltaic glass panel needs to be re-coated, the scraper 42 can scrape off the coating layer on the surface of the photovoltaic glass panel. After the coating layer is scraped off and cleaned by the roller brush 31, the nozzle 41 is used to spray the coating liquid to re-coat the cleaned photovoltaic glass panel. When using the device, lift the cleaning device and place it on one side of the photovoltaic panel so that the walking mechanism 2 can move normally on the photovoltaic panel; start the walking mechanism 2 and the cleaning mechanism 3 so that the cleaning device cleans the surface of the glass panel on the photovoltaic panel while moving; in the case where there are many sticky impurities on the glass panel, water is sprayed through the nozzle 41 during the movement of the cleaning device, and the scraper 42 is used to scrape off the stickiness on the surface of the photovoltaic glass panel to improve the cleaning effect; when the coating on the surface of the photovoltaic glass panel cracks and there are many scratches after cleaning, the coating on the surface of the photovoltaic glass panel is first scraped off by the scraper 42 during the movement of the cleaning device, and then the coating liquid is sprayed using the nozzle 41 during the movement of the cleaning device.

[0024] Embodiment 2

[0025] like Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10As shown, the difference between this embodiment and the above embodiment lies in that the nozzles 41 are all fixedly mounted on the movable mounting base 43, the upper end of the nozzle 41 is fixedly connected with a shunt pipe 411, the shunt pipe 411 is fixedly connected with an elastic telescopic hose 412, a water tank 6 is fixedly mounted on the shell 1, a water pump is installed inside the water tank 6, the elastic telescopic hose 412 penetrates the outer wall of the water tank 6, extends to the interior of the water tank 6 and is connected to the water delivery end of the water pump.

[0026] As can be seen from the above, by providing the diversion pipe 411 , the elastic telescopic hose 412 and the water pump, the liquid in the water tank 6 can be input into the nozzle 41 at a stable pressure and sprayed out through the nozzle 41 .

[0027] The rotation adjustment component 51 includes a rotating shaft 511, a rotating plate 512 and a rotation adjustment motor 513. The rotating shaft 511 is rotatably mounted on both ends of the movable mounting seat 43. The rotating plate 512 is fixedly connected to the rotating shaft 511. The rotation adjustment motor 513 is fixedly mounted on the movable mounting seat 43. A driving gear 514 is fixedly mounted on the driving end of the rotating adjustment motor 513. A driven gear 515 is fixedly mounted on one of the rotating shafts 511. The driven gear 515 is meshed and connected with the driving gear 514. The rotating plates 512 are fixedly connected via a connecting rod 516.

[0028] As can be seen from the above, since the rotating plates 512 are fixedly connected by the connecting rod 516, the two rotating plates 512 rotate synchronously. Since the driven gear 515 is meshed with the driving gear 514, the rotating adjustment motor 513 can drive the rotating shaft 511 fixedly connected to the driven gear 515 to rotate, thereby making the two rotating plates 512 fixed to each other rotate synchronously.

[0029] The telescopic adjustment assembly 52 includes a slide 521, a slider 522 and an electric push rod 523. The slide 521 is movably arranged between the rotating plates 512, the slider 522 is fixedly installed on the slide 521, a through groove 517 is opened on the rotating plate 512, the slider 522 is slidably installed inside the through groove 517, the electric push rod 523 is fixedly installed on the rotating plate 512, and the driving end of the electric push rod 523 is fixedly connected to the slider 522.

[0030] As can be seen from the above, since the slider 522 is slidably installed inside the through groove 517, the slider 522 is slidably connected to the rotating plate 512, so the slide 521 fixedly connected to the slider 522 is slidably connected to the rotating plate 512, and when the electric push rod 523 pushes the slider 522 to move, the slide 521 moves along the length direction of the through groove 517.

[0031] The adjusting mechanism 5 also includes a disassembly and assembly component 53, which includes a mounting plate 531 and a telescopic spring 532. A card slot is provided on the surface of the mounting plate 531, and the scraper 42 is detachably fixed on the card slot by bolts. Slide slots 524 are provided at both ends of the slide 521, and both ends of the mounting plate 531 are slidably installed inside the slide slot 524. The two ends of the telescopic spring 532 are fixedly connected to the mounting plate 531 and the slide slot 524 respectively.

[0032] From the above, it can be seen that since the two ends of the telescopic spring 532 are fixedly connected to the mounting plate 531 and the slide groove 524 respectively, when the scraper 42 installed on the mounting plate 531 encounters greater resistance when moving, it can retreat a certain distance, thereby reducing the probability of the scraper 42 edge being damaged, and also reducing the probability of the photovoltaic panel being scratched.

[0033] Embodiment 3

[0034] like Figure 3 and Fig.10 As shown, the difference between this embodiment and the above-mentioned embodiment lies in that the translation drive assembly 44 includes a guide rod 441, a moving belt 442 and a translation drive motor 443, both ends of the guide rod 441 are fixedly connected to the shell 1, and the guide rod 441 is slidably connected to the moving mounting seat 43, the moving belt 442 is fixedly mounted on the moving mounting seat 43, and both ends of the moving belt 442 are provided with transmission wheels 444, the transmission wheels 444 are connected to each other through the moving belt 442, and the transmission wheels 444 are rotatably mounted on the shell 1, the translation drive motor 443 is fixedly mounted on the shell 1, and the driving end of the translation drive motor 443 is fixedly connected to one of the transmission wheels 444.

[0035] As can be seen from the above, by setting the guide rod 441, since the guide rod 441 is slidingly connected to the movable mounting seat 43, the movable mounting seat 43 can only move in a straight line. By setting the moving belt 442 and the transmission wheel 444, when the translation drive motor 443 drives the transmission wheel 444 to rotate, the moving belt 442 pulls the movable mounting seat 43 to move in a straight line.

[0036] Embodiment 4 like Figure 3 As shown, the difference between this embodiment and the above embodiment is that the walking mechanism 2 includes an anti-skewness wheel 21, a support wheel 22 and a walking drive motor 23, the anti-skewness wheel 21 and the support wheel 22 are rotatably installed at both ends of the shell 1, the anti-skewness wheel 21 is in rolling contact with the side of the photovoltaic glass panel, the support wheel 22 is in rolling contact with the edge of the upper surface of the photovoltaic glass panel, the support wheels 22 on the same side are connected by a transmission pulley, the walking drive motor 23 is fixedly installed on the shell 1, and the driving end of the walking drive motor 23 is fixedly connected to the support wheel 22.

[0037] As can be seen from the above, the anti-deviation wheel 21 is provided to prevent the cleaning device from being deflected when walking on the photovoltaic panel, and the support wheel 22 can drive the shell 1 to move back and forth under the control of the walking drive motor 23.

[0038] Embodiment 5

[0039] like Figure 2 , Figure 3 and Fig.11 As shown, the difference between this embodiment and the above embodiment is that the roller brushes 31 are symmetrically arranged on both sides of the shell 1, and the roller brushes 31 are connected by a transmission pulley, and the cleaning mechanism 3 also includes a cleaning drive motor 32, the cleaning drive motor 32 is fixedly mounted on the shell 1, and the driving end of the cleaning drive motor 32 is fixedly connected to one of the roller brushes 31.

[0040] As can be seen from the above, since the roller brushes 31 are connected by a transmission pulley, the two roller brushes 31 rotate in the same direction, and the roller brushes 31 rotate to clean the surface of the photovoltaic panel without sweeping dust to the side that has already been cleaned.

[0041] A partition 11 is installed inside the shell 1, and the partition 11 is arranged between the roller brush 31 and the movable mounting seat 43. A baffle 12 is also slidably installed on the shell 1, and the baffle 12 is arranged below the roller brush 31. A magnet 13 is installed at the end of the baffle 12, and the magnet 13 is magnetically attracted to the partition 11.

[0042] As can be seen from the above, by setting the partition 11, dust can be blocked. During the rotation of the roller brush 31, dust will not be thrown onto the nozzle 41 and the scraper 42 by the roller brush 31. By setting the baffle 12, when spraying the coating liquid, the baffle 12 is moved to close the roller brush 31, so that the roller brush 31 will not contact the coating liquid just sprayed on the photovoltaic panel. In this embodiment, the roller brush 31 uses a cylindrical brush with long bristles or a cylindrical sponge brush, which can be squeezed and deformed by the baffle 12. By setting the magnet 13, the baffle 12 will not open due to shaking after being closed.

[0043] Embodiment 6

[0044] See also Figure 1 - Fig.11 The present invention also discloses a method for cleaning a photovoltaic panel, the specific steps of which are: Lift the cleaning device and place it on one side of the photovoltaic panel so that the walking mechanism 2 can walk normally on the photovoltaic panel; Start the walking mechanism 2 and the cleaning mechanism 3 so that the cleaning device cleans the surface of the glass panel on the photovoltaic panel during the walking process; In the case where there are many sticky impurities on the glass panel, water is sprayed through the nozzle 41 during the movement of the cleaning device, and the scraper 42 is used to scrape off the stickiness on the surface of the photovoltaic glass panel to improve the cleaning effect; When the coating on the photovoltaic glass panel surface is cracked and there are many scratches after cleaning, the coating on the photovoltaic glass panel surface is first scraped off by the scraper 42 during the movement of the cleaning device, and then the coating liquid is sprayed using the nozzle 41 during the movement of the cleaning device back.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
