[0002] Photovoltaic panels are devices that absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. Compared with ordinary batteries and rechargeable batteries, photovoltaic panels are more energy-saving and environmentally friendly green products. When photovoltaic panels are installed outdoors and used for a long time, the fine dust particles, dust or fallen leaves attached to their surface will affect the transmittance of light and the amount of radiation received by the surface of the photovoltaic panels, which will also reduce the energy conversion efficiency of the photovoltaic panels. Therefore, it is necessary to frequently use a cleaning device to clean the surface of the photovoltaic panels.

[0003] However, there are various types of cleaning devices in the prior art. For example, utility model patent CN212041652U relates to a photovoltaic panel surface cleaning device, which is provided with a bottom box, a groove is provided in the bottom box, a horizontal plate is provided at the upper end of the groove, the horizontal plate is slidably connected to the inner wall of the groove, a telescopic rod and a screw are provided below the horizontal plate, the telescopic rod is located on the left and right sides of the screw, the bottom of the bottom box is provided with a forward and reverse bidirectional motor, the forward and reverse bidirectional motor is provided with a first rotating shaft, the first rotating shaft is located directly below the screw, a screw sleeve is provided between the first rotating shaft and the screw, a screw sleeve is provided in the screw sleeve for the screw to enter the thread groove, the screw is located in the screw sleeve, the screw sleeve is threadedly connected to the screw, the lower surface of the screw is fixedly connected to the first rotating shaft, a suction pump is provided on the left side of the groove, and a through groove is connected to the suction pump.

The present invention provides the following embodiments.

[0026] like Figure 1 , Figure 2 as well as Figure 4 As shown, it is a structural schematic diagram of the photovoltaic panel surface cleaning device in this embodiment. The cleaning device in this embodiment includes a mounting support plate 1, a fixing rod 2 is fixedly connected between the two mounting support plates 1, a bearing plate 3 is fixed between the two mounting support plates 1, a connecting seat 20 is arranged on the top of the fixing rod 2, and a handle 21 is fixedly connected to one end of the connecting seat 20, a water pipeline 5 is arranged between the two mounting support plates 1 through a fixing member 4, and a plurality of first nozzles 6 and second nozzles 7 are equidistantly arranged on the outer surface of the water pipeline 5.
