[0030] In this embodiment, the infrared camera 21 is installed at the bottom of the top plate of the sliding seat 8 and is located between the second scraper 17 and the partition 802.

[0031] It should be noted that the arrangement position of the infrared camera 21 enables it to clearly capture the situation on the surface of the photovoltaic panel, while avoiding direct contact with the cleaning module, reducing the potential pollution risk. The cleaning module has a compact structure and perfect functions. Through the cooperation of the second rotating rod 11 and the slider 12, the reciprocating movement of the first scraper 13 is realized, improving the cleaning efficiency.

[0032] In this embodiment, the fixed seat 10 is bolted to the bottom of the top plate of the sliding seat 8. A sliding groove is formed inside the fixed seat 10.

[0035] In this embodiment, the first scraper 13 is bolted to the bottom of the slider 12. A plurality of connected inverted U-shaped water tanks are formed inside the fixed seat 10 and located inside the sliding groove. A plurality of water outlet valves 14 are installed at the water outlet ends of the bottoms of the plurality of inverted U-shaped water tanks.

[0036] It should be noted that the design of the inverted U-shaped water tank enables the water to be evenly distributed on the surface of the photovoltaic panel 2, improving the cleaning effect.

[0038] Working principle: When the system starts up, the top of the photovoltaic panel 2 is smoothly moved upward along the chute of the support plate 1 by the infrared camera 21 through the sliding seat 8 driven by the first motor 7. The T-shaped slider 801 ensures stable sliding. At this time, the electronic telescopic rod 18 drives the second scraper 17 to move upward. Then, the infrared camera accurately identifies the position of the obstacles on the surface of the photovoltaic panel, and the information is transmitted to the controller 9. Subsequently, the controller 9 controls the cleaning module to work. The second rotating rod 11 rotates under the drive of the second motor 23, and drives the slider 12 and the first scraper 13 to reciprocate in the sliding groove through threaded connection to scrape the dirt on the surface of the photovoltaic panel. During the cleaning process, the water in the water tank 3 is pumped into the inverted U-shaped water tank in the sliding seat 8 through the long pipeline 16 by the water pump 19 and is sprayed out in a timely manner under the control of the water outlet valve 14 to assist in cleaning and wash away the dirt. After cleaning to the top, the first motor 7 rotates in the reverse direction to drive the sliding seat 8 to move downward. At this time, the electronic telescopic rod 18 drives the second scraper 17 to move downward and get stuck with the sliding seat 8, and the second scraper 17 contacts the top of the photovoltaic panel 2 at this time to scrape the cleaned dirt into the recycling box 20. Finally, it can be conveniently taken out and processed through the handheld part. The whole process realizes the automatic inspection and efficient cleaning of the photovoltaic module.

[0039] The inspection device for component board occlusion of the photovoltaic module, through the design of the rectangular through hole at the top of the photovoltaic panel 2 and the recycling box 20, effectively collects the sundries cleaned during the inspection process. In the inspection and cleaning component, the first rotating rod 6 rotates under the drive of the first motor 7 to drive the sliding seat 8 to move smoothly along the chute. The T-shaped slider 801 ensures the close fit between the sliding seat and the support plate. The partition 802 in the sliding seat separates the infrared camera 21 from the cleaning module. The infrared camera accurately identifies the position of the obstacles, and the cleaning module is responsible for removal. The flexible adjustment of the second scraper 17 and the electronic telescopic rod 18 enhances the pertinence and effect of cleaning. In the cleaning module, the second rotating rod 11 drives the slider 12 and the first scraper 13 to reciprocate through threaded connection under the drive of the second motor 23 to scrape the dirt on the surface of the photovoltaic panel. At the same time, the design of the inverted U-shaped water tank and the water outlet valve 14, combined with the water pump 19 and the long pipeline 16, realizes automatic water supply and drainage during the cleaning process, ensuring the cleaning efficiency and effect.
