[0002] Solar photovoltaic panels, also known as solar panels, are devices that convert sunlight radiation energy directly into electrical energy. They work mainly based on the photoelectric effect of semiconductors. They are usually composed of multiple solar cell units, which are generally made of semiconductor materials such as silicon. Solar photovoltaic panels are widely used in the field of renewable energy, such as solar power stations, solar street lights, distributed rooftop photovoltaic power generation systems and many other scenarios. After long-term use, the surface of photovoltaic panels is easily contaminated with dust, dirt and other pollutants, which will reduce the transmittance of sunlight and affect the use effect of solar photovoltaic panels.

[0003] In the prior art, when using a solar photovoltaic panel cleaning machine, a worker needs to push the cleaning machine to the top of the solar photovoltaic panel and then start the cleaning machine for cleaning. During the cleaning process, the position between the cleaning machine and the photovoltaic panel will deviate, causing the cleaning roller in the cleaning machine to not start cleaning from the edge of the photovoltaic panel, which may easily lead to some areas not being cleaned, leaving a blind spot for cleaning, thereby affecting the cleaning effect of the solar photovoltaic panel.

[0039] In this embodiment, when in use, the positioning prompt light 316, the forward and reverse motors 401, the pressure sensor 410 and the PLC controller 315 are electrically connected, and a universal wheel is installed at the bottom of the mobile frame 202, which pushes the mobile frame 202 and the support frame 201 in the direction of the photovoltaic panel body 1, so that the support frame 201 gradually moves to the outer surface of the photovoltaic panel body 1. At this time, the two rotating wheels 305 located at the rear move to the top of the photovoltaic panel body 1 near both sides, and the side wheels 306 at the rear move to the side of the photovoltaic panel body 1, and one end of the positioning rod 407 contacts the front surface of the photovoltaic panel body 1.

The driving mechanism 303 is mainly composed of a driving motor, a plurality of gears and a bevel gear. The driving motor drives the gear to rotate, and then drives the meshing multiple gears and bevel gears to rotate, thereby driving the connecting rod 304, the rotating wheel 305, the side wheel 306 and the cleaning roller body 307 to rotate. After the cleaning point is positioned by the positioning assembly 4, one end of the clamping rod 206 is pushed downward to rotate to the inside of the self-locking groove 204. Under the action of the damping shaft 205, the other end of the clamping rod 206 is rotated out of the arc hole 319 and rotated into the self-locking groove 204. At this time, the cleaning assembly 3 loses its fixation and becomes movable. The driving mechanism 303 is started to drive the rotating wheel 305 and the side wheel 306 to rotate at the top and side of the photovoltaic panel body 1 respectively, further driving the entire cleaning assembly 3 to move from the front to the rear of the top of the photovoltaic panel body 1, thereby driving the cleaning roller body 307 to rotate, and cleaning is performed from the front edge of the top of the photovoltaic panel body 1 to the rear edge.

Then continue to slowly push the support frame 201 to move, the positioning rod 407 is limited by the photovoltaic panel body 1, and the movable block 406 is pushed in the reverse direction to move forward in the positioning cylinder 405, and at the same time, the rubber rod 408 is pushed to move in the direction of the pressure sensor 410 and squeeze the spring 409. As the moving component 2 continues to move, the rubber rod 408 will gradually contact the pressure sensor 410 and generate pressure. The pressure sensor 410 will transmit the detected pressure data to the PLC controller 315 in the form of an electrical signal. The maximum and minimum working thresholds of the pressure data are set in advance inside the PLC controller 315. The PLC controller 315 will identify and compare the received pressure data. When the pressure data meets the set pressure value range, the PLC controller 315 will control the positioning prompt light 316 to light up, reminding the staff to stop pushing the equipment to move. At this time, the cleaning roller body 307 is just located at the edge of the top of the photovoltaic panel body 1, which is conducive to the subsequent cleaning roller body 307 starting from the edge of the top of the photovoltaic panel body 1 to clean, avoiding some areas from being left uncleaned. Under the action of the positioning assembly 4, the cleaning point positioning effect is achieved, which is conducive to more comprehensive cleaning in the future and improves the cleaning effect. After the positioning is completed, the forward and reverse motors 401 are started to drive the rotating rod 402 to rotate, and further drive the fixing rod 404, the positioning cylinder 405 and the positioning rod 407 to rotate together, and rotate from the bottom of the cleaning box 301 to the front surface. At this time, after the positioning rod 407 rotates away from the front surface of the photovoltaic panel body 1, it loses the squeezing force. Under the resilience of the spring 409, the positioning rod 407 is pushed to move outward and reset, which does not affect the subsequent cleaning assembly 3 to move and clean on the top of the photovoltaic panel body 1. One end of the card rod 206 is pushed downward to rotate to the inside of the self-locking groove 204. Under the action of the damping shaft 205, the other end of the card rod 206 is rotated out of the arc hole 319 and rotated into the self-locking groove 204. At this time, the cleaning component 3 loses its fixation and becomes movable. The driving mechanism 303 is started to drive the rotating wheel 305 and the side wheel 306 to rotate at the top and side of the photovoltaic panel body 1 respectively, further driving the entire cleaning component 3 to move from the front to the rear of the top of the photovoltaic panel body 1, thereby driving the cleaning roller body 307 to rotate and clean from the front edge of the top of the photovoltaic panel body 1 to the rear edge. The water supply mechanism 309 is started to transport the water in the water tank 308 to the water supply pipe 310 through the connecting pipe, and then enters the two water outlet pipes 312 through the connecting piece 311, and sprays water to the top of the photovoltaic panel body 1 through the water spray pipe 313 for cleaning.When the cleaning component 3 moves from the front to the back of the photovoltaic panel body 1, the driving mechanism 303 drives the rotating wheel 305 and the side wheel 306 in reverse to rotate, so that the cleaning component 3 moves from the back to the front to reset, and then the clamping rod 206 is pushed again so that the other end of the clamping rod 206 is inserted into the arc hole 319 again, fixing the cleaning component 3 on the support frame 201, so as to facilitate the subsequent pushing of the equipment to another solar photovoltaic panel for cleaning.

[0043] Among them, the driving mechanism 303, the water supply mechanism 309, the solar power supply mechanism 314, the PLC controller 315, the positioning prompt light 316, the forward and reverse motor 401 and the pressure sensor 410 are all existing technologies, and their components and operating principles are all public technologies, so no excessive explanation is given here.
