[0030] Working Principle: Photovoltaic power stations are generally equipped with rows of photovoltaic panel assemblies. The photovoltaic panel assemblies are composed of photovoltaic panels arranged in parallel. Generally, the photovoltaic panels are set at an angle, and a support frame is set at the bottom to fix the photovoltaic panels. When the photovoltaic panels are in use, dust may accumulate on the surface of the photovoltaic panels, which needs to be removed.
[0031] During dust removal, the device is moved to a position corresponding to the photovoltaic panel assemblies arranged in a row, and then the motor 510 is energized to rotate the screw 509. Since the screw 509 is threadedly connected to the second rotating frame 507, the second rotating frame 507 is driven to move downward, and then the connecting block 503 on the mounting cover 401 is rotated around the fixed axis on the fixed rotating seat 504 through the connecting rod 506, and the mounting cover 401 is adjusted to a state where the inclination angle is the same as the inclination angle of the photovoltaic panel. At the same time, the cylinder 502 is turned on to move the mounting cover 401 downward until the bottom ends of the cleaning cloth roller 403 and the scraper 402 contact the surface of the photovoltaic panel.
[0032] Then the control device is moved along the length direction of the rows of photovoltaic panel assemblies. During the movement, the scraper 402 continuously scrapes the dust on the surface of the photovoltaic panel, and at the same time, the valve 409 is opened, so that the water flow on the water tank 407 continues to slowly pass through the connecting hose 410, the top tube 404, the distribution cavity 405 and the distribution hole 406 flow channel cleaning cloth roller 403. During the movement, the cleaning cloth roller 403 continuously rotates to wipe the surface of the photovoltaic panel to improve the dust removal effect. By adjusting the opening of the valve 409, the water flow rate can be controlled.
[0033] When the ground at the location that needs to be cleaned is uneven, the staff will rotate the support stud 205 by turning the handle 208. Since the support stud 205 is threadedly installed inside the fixed screw barrel 204, it drives the support stud 205 to move longitudinally. Since the top of the support stud 205 is hinged with a hinge rod 207, the top of the hinge rod 207 is hinged to the top plate 3, and the other end of the top plate 3 is rotatably connected to the fixed column 201 through the top swivel seat 202 and the connecting block 203, it is convenient to adjust the equipment on uneven ground, facilitate the movement of the equipment, and facilitate cleaning.
