Working method of automatic cleaning and dust removing device for surface of photovoltaic panel

The invention discloses a working method of an automatic cleaning and dust removing device for the surface of a photovoltaic panel. The problem of how to develop a convenient and efficient cleaning device is solved. A left upper cantilever beam (4) and a left lower cantilever beam (5) which horizontally extend leftwards are fixedly arranged at the left end of the rectangular frame (1), a right upper cantilever beam (6) and a right lower cantilever beam (7) which horizontally extend rightwards are fixedly arranged at the right end of the rectangular frame (1), and a left rotating lead screw (8) is movably arranged between the left upper cantilever beam (4) and the left lower cantilever beam (5). A left screw nut sliding block (14) is connected to the left rotating screw in a threaded mode, a right screw nut sliding block (15) is connected to the right rotating screw (9) in a threaded mode, a connecting cross rod (18) is arranged between a left T-shaped support (16) and a right T-shaped support (17), a scraper
