Two tilted fixing plates 3 are fixedly installed on the L-shaped bracket 1 and located on both sides of the photovoltaic panel 2. The length of the fixing plate 3 exceeds the photovoltaic panel 2. A threaded block 4 is slidably installed on the fixing plate 3. The fixing plate 3 is provided with a A driving device is provided to drive the threaded block 4 to move, and a cleaning component is provided between the two threaded blocks 4. After the cleaning agent is sprayed onto the surface of the photovoltaic panel 2, the cleaning component is started to clean the surface of the photovoltaic panel 2.

[0027] like Figure 1-4 As shown, the water spray assembly includes a water tank 15 fixedly mounted on the L-shaped bracket 1, and also includes an L-shaped fixed block 13 fixedly mounted on one side of the L-shaped bracket 1, a self-priming pump 6 is fixedly mounted on the top of the L-shaped fixed block 13, the self-priming pump 6 and the water tank 15 are connected by a water delivery pipe 14, a water outlet pipe 7 is fixedly connected to one side of the self-priming pump 6, a spray pipe 8 is fixedly mounted on the end of the water outlet pipe 7, a plurality of evenly distributed water spray holes are opened at the bottom of the spray pipe 8 along the length direction of the spray pipe 8, a guide plate 9 located below the water spray hole is fixedly mounted at the end of the photovoltaic panel 2, the self-priming pump 6 is started, the cleaning liquid is sucked from the water tank 15 into the self-priming pump 6 through the water delivery pipe 14, and then transported to the spray pipe 8 through the water outlet pipe 7, and sprayed onto the guide plate 9 through the water spray holes opened at the bottom of the spray pipe 8, the cleaning liquid will flow downward along the inclination angle of the photovoltaic panel 2, so as to spray the entire surface of the photovoltaic panel 2.

[0028] like Figure 1-6 As shown, the cleaning assembly includes a scrub brush 12 fixedly mounted between two threaded blocks 4. The bristles of the scrub brush 12 are nylon bristles. Nylon bristles usually have good elasticity and softness, causing the gentlest friction to the surface of an object, and are more suitable for brushing the surface of sensitive equipment such as photovoltaic panels 2.

The self-priming pump 24 is connected to the water tank 15 by a pumping pipe. When the driving device drives the cleaning component to the top of the maintenance mechanism, the electric telescopic rod 20 is started to lift the scraper 22 to the inside of the bristles of the plate brush 12.

The self-priming pump 24 working with it sucks the cleaning liquid out of the water tank 15 through the suction pipe, and transports it to the cavity of the scraper 22 through the hose 23, and then sprays it out through the water outlet 2201 set on the upper end surface of the scraper 22. The scraper 22 rinses the cleaning component while scraping impurities from the cleaning component, further cleans the cleaning component, and greatly reduces the impurities on the cleaning component.

[0031] Working principle: When dust accumulates on the photovoltaic panel 2, the self-priming pump 6 is started, and the cleaning liquid is sucked from the water tank 15 into the self-priming pump 6 through the water pipe 14, and then transported to the spray pipe 8 through the outlet pipe 7, and sprayed onto the guide plate 9 through the water spray hole opened at the bottom of the spray pipe 8. The cleaning liquid will flow downward along the inclination angle of the photovoltaic panel 2 to spray the entire surface of the photovoltaic panel 2. The motor 10 is started to drive the threaded rod 25 to rotate. Due to the limiting effect of the notch, the threaded block 4 threadedly connected to the threaded rod 25 moves in the notch, driving the cleaning component to move on the surface of the photovoltaic panel 2, so as to clean the entire surface of the photovoltaic panel 2 and clean it more comprehensively. When the driving device drives the cleaning component to reach the top of the maintenance mechanism, the electric telescopic rod 2 0 is started, the scraper 22 is raised to the inside of the bristles of the scrub brush 12, and at the same time, the motor 26 is started, the screw 18 rotates, and the moving block 19 threadedly connected to the screw 18 moves under the action of the guide rod 17, and the scraper 22 above the moving block 19 repeatedly scrapes the bristles of the entire scrub brush 12, and the self-priming pump 24 working with it sucks the cleaning liquid out of the water tank 15 through the suction pipe, and transports it to the cavity of the scraper 22 through the hose 23, and then sprays it out through the outlet 2201 set on the upper end surface of the scraper 22. The scraper 22 rinses the cleaning component while scraping impurities from the cleaning component, and further cleans the cleaning component, greatly reducing impurities on the cleaning component, allowing the cleaning component to be put into cleaning work more quickly, and improving the cleaning efficiency.
