When there is a lot of snow on the surface of the photovoltaic panel in winter, the motor 22 on the outer surface of the vertical block 21 is operated, and the screw 23 is driven to rotate by the forward and reverse rotation of the motor 22. When the screw 23 rotates, the inner wall of the sliding rod 26 will move on the outer surface of the screw 23 and the outer surface of the round rod 25 respectively. The rotation of the screw 23 makes the sliding rod 26 and the push plate 29 move toward the direction of the motor 22, and the snow on the surface of the photovoltaic panel 1 is pushed downward by the push plate 29. During the movement of the moving rod 26, the wheels 211 at both ends of the rectangular rod 210 will respectively enter the outer surfaces of the guide rods 214 on the outer surfaces of the two semicircular plates 24. When the wheel 211 on the left side of the rectangular rod 210 moves to the protrusion on the outer surface of the guide rod 214, the rectangular rod 210 will move to the right, driving the rotating rod 28 and the push plate 29 to move to the right. When the wheel 211 on the right side of the rectangular rod 210 moves to the protrusion on the outer surface of the guide rod 214, the rectangular rod 210 will move to the left, driving the rotating rod 28 and the push plate 29 to move to the left, so that the push plate 29 moves toward the direction of the motor 22 and moves horizontally to the left and right to enhance the cleaning effect of the snow on the surface of the photovoltaic panel 1. At the same time, the sliding rod 26 moves During the process, the first gear 217 at one end meshes with the outer surface of the first gear rod 216, which will drive the first gear 217 and the half gear 218 to rotate. When the outer surface of the half gear 218 meshes with the outer surface of the second gear rod 219, it will drive the second gear rod 219 to move toward the top of the photovoltaic panel 1 and stretch the second spring 223, so that the piston block 221 at one end of the cylindrical rod 220 slides inward on the inner wall of the cylinder 222. When the half gear 218 is away from the outer surface of the second gear rod 219, the second spring 223 will return to its original state and pull the second gear rod 219 to move the piston block 221 outward on the inner wall of the cylinder 222. The piston block 221 repeatedly moves the cylinder 222 to compress the cylinder 222. The air inside the cylinder 222 is pumped into the copper tube 225 through the air pipe 224. The air moves on the inner wall of the copper tube 225 and rubs against the inner wall of the copper tube 225 to generate heat for the copper tube 225. At the same time, when the sliding rod 26 moves, a long rope 227 is pulled through the rectangular block 226 and released at the bottom end of the outer surface of the rotating shaft 229. Another long rope 227 is wound around the bottom end of the outer surface of the rotating shaft 229 to drive the rotating shaft 229 to rotate. The fan blades 230 are driven by the rotating shaft 229 to rotate and the hot air near the surface of the copper tube 225 is blown to the bottom of the photovoltaic panel 1 to heat the bottom of the photovoltaic panel 1, increase the melting rate of the snow on the surface of the photovoltaic panel 1, and further increase the cleaning effect.
