Automatic cleaning device for solar photovoltaic panel

The utility model belongs to the technical field of automation equipment, and particularly relates to an automatic cleaning device for a solar photovoltaic panel. The solar photovoltaic panel comprises a photovoltaic panel base, and a solar photovoltaic panel group is arranged in the photovoltaic panel base. When the solar photovoltaic panel group needs to be cleaned, the water spraying cleaning part sprays water to wash the solar photovoltaic panel group to remove large dirt on the solar photovoltaic panel group, and after washing is completed, the multi-roller synchronous cleaning assembly is moved to clean the solar photovoltaic panel group. Multi-roller synchronous cleaning is conducted on the surface of the solar photovoltaic panel set through the multi-roller synchronous cleaning assembly, dirt which is not washed away is removed, multi-roller synchronous rolling cleaning is adopted, hard collision with the surface of the solar photovoltaic panel set is avoided, meanwhile, the effective cleaning area is
