Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, and more particularly to an automatic cleaning device for photovoltaic panels. Background Art

[0002] In existing technologies, existing automatic photovoltaic panel cleaning devices may lack flexibility when cleaning the surface of photovoltaic panels. This may be because the cleaning mechanism of the device is not designed with sufficient precision to effectively clean the different curves and angles of the photovoltaic panels. Therefore, during the cleaning process, the device may not be able to completely cover all parts of the photovoltaic panel, resulting in unsatisfactory cleaning effects and leaving stains and moisture.

[0003] After cleaning, water stains may remain on the surface of the photovoltaic panels, which will affect the power generation efficiency of the photovoltaic panels. The current device requires a scraper to remove these water stains after use, but the existing device lacks a component for quickly releasing the scraper. This means that during the operation of scraping off the water stains, the operator may need to spend extra time and energy to manually release the scraper, which increases the complexity and time cost of maintenance.

[0004] During the cleaning process, stable fixation of the scraper is the key to ensuring the cleaning effect. However, existing devices may not be able to stably fix the scraper. This may be due to the scraper fixing component being designed not strong enough or lacking an effective locking mechanism. This instability may cause the scraper to shift or fall off during the cleaning process, affecting the cleaning effect and even damaging the photovoltaic panel. Utility Model Content
