[0002] Photovoltaic panel surface cleaning devices are crucial for ensuring the efficiency of photovoltaic power generation. Traditional manual or simple brushing methods suffer from incomplete cleaning, low efficiency, and easy scratching of the panel surface, making it difficult to meet the demands of large-scale power plants for high power generation rates and low operation and maintenance costs. With the continuous expansion of photovoltaic installations, there is an urgent need for an efficient, safe, and remotely controllable automatic cleaning device to quickly remove dust, bird droppings, and other obstructions, improve sunlight utilization, extend module lifespan, and ensure the stable and efficient operation of the photovoltaic system.
[0003] Patent publication number CN222491137U discloses a photovoltaic panel surface cleaning device, including a photovoltaic panel body, a moving mechanism, and a cleaning mechanism.

A connecting block is connected to one side of the slider, and a rotating hole is drilled in the connecting block. The cleaning mechanism is connected to the photovoltaic panel body.

[0024] The present invention will be further described in detail below with reference to embodiments:
[0025] Example 1
[0026] like Figure 1-5 As shown, this utility model provides a photovoltaic panel surface cleaning device, including a cleaning mechanism 1. A water supply control device 2 is installed on the bottom surface of the cleaning mechanism 1, and a movable lifting mechanism 3 is installed on the bottom surface of the water supply control device 2. The movable lifting mechanism 3 includes a lifting frame top plate 36, which is fixedly connected to the bottom surface of the water supply control device 2. A slot is opened on the side of the lifting frame top plate 36, and a cam follower 35 is slidably connected to the slot. One end of the cam follower 35 is rotatably connected to a scissor-type lifting frame 37, and a second scissor-type lifting frame 312 is rotatably connected to the middle of the first scissor-type lifting frame 37.

[0027] In this embodiment, the stepper motor 39 is started, which drives the lead screw 38 to move, thereby promoting the movement of the movable block 34. This causes the cam follower 1 35 and the cam follower 2 310 to move left and right in the slot, thereby allowing the scissor lift frame 1 37 and the scissor lift frame 2 312 to move up and down. The top plate 36 of the lift frame is adjusted to a suitable height. Finally, the device is started, and the moving wheel 32 moves in the designated direction, so that the device moves to perform a large-scale rinsing of the photovoltaic panel, ensuring the adaptability of cleaning on photovoltaic panels at different heights.

[0030] In this embodiment, the water source is connected to the input end of the water pump 25, and the water is transmitted to the water supply pipe 27 through the inlet pipe 26 at the output end. After passing through the connecting hose 28, the switch 24 is finally turned on, which makes the device move, thus solving the problem of water flow transmission and improving the convenience of the device.

Through the connecting arm 13, the cleaning brush device 11 can be adjusted to a suitable angle to fit closely to the photovoltaic panel. Then, water is introduced into the cleaning brush device 11 from the water inlet 12. The rotating motor 112 drives the rotating column 113 to rotate, thereby prompting the brush 114 to clean. At the same time, the impact water gun 115 is used for rinsing. The cleaning brush device performs two cleanings, which improves the cleaning ability and work efficiency of the photovoltaic panel.
[0034] The working principle of this photovoltaic panel surface cleaning device will be explained in detail below.
[0035] like Figure 1-5 As shown, when in use, place the device in the designated position, start the stepper motor 39, drive the lead screw 38 to move, thereby promoting the movement of the movable block 34, so that the cam follower 1 35 and the cam follower 2 310 move left and right in the groove, thereby allowing the scissor lift frame 1 37 and the scissor lift frame 2 312 to move up and down, adjusting the top plate 36 of the lift frame to a suitable height, start the main motor 16 to drive the rotating shaft 15 to rotate, and use the rotating shaft limiting base 14 to limit it. Through the connecting arm 13, the cleaning brush device 11 can be adjusted to a suitable angle to fit closely to the photovoltaic panel. The water source is connected to the input end of the water pump 25, and the output end is transmitted to the water supply pipe 27 through the water inlet pipe 26. After passing through the connecting hose 28, the water enters the cleaning brush device 11 from the water inlet 12. The rotating motor 112 drives the rotating column 113 to rotate, thereby causing the brush 114 to clean. At the same time, the impact water gun 115 is used for rinsing. Finally, the switch 24 is turned on, so that the device moves to rinse the photovoltaic panel over a large area.
