Slide grooves 111 are provided on both sides of the outer surface of the mounting plate 102, and the two ends of the cleaning brush 110 are slidably mounted in the two slide grooves 111. A motor is fixedly mounted on the upper side of the mounting plate 102. 109. A drive wheel 107 is installed on the drive end of the motor 109. A driven wheel 106 is fixedly installed on the outer surface of one of the rotating shafts 103. A transmission belt 108 is sleeved and connected to the outer surface of the driven wheel 106 and the drive wheel 107. The mounting plate 102 is rotatably installed inside the support frame 101. A hydraulic telescopic rod 112 is rotatably connected to the top of the inner surface of the support frame 101. The drive end of the hydraulic telescopic rod 112 is rotatably installed on the upper surface of the mounting plate 102. The lifting assembly includes a support leg 202 and a threaded rod 204. The support leg 202 slides... Installed inside the lifting leg 201, the threaded rod 204 is rotatably installed inside the lifting leg 201, the support leg 202 is threaded onto the outer surface of the threaded rod 204, the lifting leg 201 has a rotating shaft 207 rotatably installed inside, the outer surface of the rotating shaft 207 has a bevel gear 206 fixedly installed, one end of the threaded rod 204 is fixedly connected to a bevel gear 205, the bevel gear 205 meshes with the bevel gear 206, one end of the rotating shaft 207 is fixedly installed with a knob 208, and one end of the support leg 202 is fixedly installed with a support plate 203.

[0032] In this embodiment, during use, the support frame 101 is first placed at a suitable position above the photovoltaic panel. Based on the installation angle of the photovoltaic panel, the hydraulic telescopic rod 112 in the rotating assembly is activated. The hydraulic telescopic rod 112 is rotatably installed between the mounting plate 102 and the support frame 101. The mounting plate 102 is rotatably installed inside the support frame 101. Driven by the hydraulic telescopic rod 112, the mounting plate 102 can be rotated inside the support frame 101, adjusting the angle of the cleaning assembly relative to the support frame 101 so that the cleaning brush 110 is parallel to the surface of the photovoltaic panel.

The hydraulic telescopic rod 112 is rotatably installed between the mounting plate 102 and the support frame 101. The mounting plate 102 is rotatably installed inside the support frame 101. Driven by the hydraulic telescopic rod 112, the mounting plate 102 can be rotated inside the support frame 101, adjusting the angle of the cleaning assembly relative to the support frame 101 so that the cleaning brush 110 is parallel to the surface of the photovoltaic panel. Then, the distance between the cleaning assembly and the photovoltaic panel is adjusted by adjusting the lifting assembly to ensure that the cleaning brush 110 can closely adhere to the surface of the photovoltaic panel. First, the knob 208 is rotated, which drives the rotating shaft 207 to rotate inside the lifting leg 201. A bevel gear 206 is fixedly installed on the outer surface of the rotating shaft 207. A threaded rod 204 is rotatably installed inside the lifting leg 201, allowing the threaded rod 204 to rotate freely. A bevel gear 205 is installed at the top of the threaded rod 204. Through the meshing between the bevel gear 205 and the bevel gear 206, the threaded rod 204 can be driven to rotate. The support leg 202 is threaded onto the outer surface of the threaded rod 204, and the outer surface of the support leg 202 is limited by the lifting leg 201, thus enabling the support leg 202 to rise and fall inside the lifting leg 201. This ensures that the cleaning brush 110 can closely adhere to the surface of the photovoltaic panel. A support plate 203 is fixedly installed at the bottom of the support leg 202. The support plate 203 increases the contact area between the device and the ground, thereby improving the stability of the device.
