[0002] A photovoltaic panel cleaning device is a mechanical device specifically used for cleaning the surface of photovoltaic panels. It mainly relies on mechanical force or physical acting force, such as using brushes, high-pressure water, gas, etc. to clean the photovoltaic panels. The purpose is to remove obstacles such as dust, dirt, and bird droppings on the photovoltaic panels, so as to improve the power generation efficiency of photovoltaic modules and extend their service life. According to the usage scenarios, it can be divided into various types such as large, medium, and small, and can also be divided into types such as manual, semi-automatic, and fully automatic.

At this time, the surface of the round brush 21 contacts the photovoltaic panel to be cleaned to achieve the cleaning effect. During operation, the height of the driving motor 23 can be freely adjusted according to the usage scenario. At this time, turn on the machine, and the driving motor 23 drives the long brush 24 to rotate. The bristles on the surface of the long brush 24 will contact the photovoltaic panel to achieve the cleaning effect. During operation, the second base 3 is fixedly connected to the first base 1, and at the same time, the second base 3 is hinged to the hydraulic base 31, so that the hydraulic base 31 can freely adjust the angle with the first base 1. At the same time, the hydraulic base 31 can adjust its length according to the needs of the working environment. The operation handle 32 at the top of the hydraulic base 31 can be used for workers to hold when operating the machine. During operation, the control base 4 fixes the liquid crystal monitor console 41 on the hydraulic base 31. When the hydraulic base 31 expands and contracts, the control base 4 and the liquid crystal monitor console 41 also expand and contract at the same time. During operation, by operating the liquid crystal monitor console 41, turn on the real-time monitoring function of the radar image detector 5. When the radar image detector 5 detects foreign objects or difficult-to-clean dirt in front of the cleaning area, it will feedback the information to the liquid crystal monitor console 41, and then decide whether to spray the cleaning liquid through the cleaning liquid outlet 16. At the same time, it is also possible to set automatic spraying or manual spraying of the cleaning liquid through the liquid crystal monitor console 41.
