Once the spray water tank fails, maintenance is very troublesome. The existing photovoltaic panel spray device has no stirring structure, and the different densities of the cleaning agent and water easily lead to stratification during operation, which reduces the cleaning effect of the sprayed cleaning mixture.

[0024] See also Figure 2 The lower walls of the two threaded sleeves 8 are respectively provided with anti-skid pads 20. In this embodiment, the anti-skid pads 20 increase the friction with the ground and enhance the stability.

[0025] In this embodiment, when the operator disassembles and assembles the spray water tank 9, he pulls out the limit pin 6, and then removes the limit block 5 along the slide groove 4. After that, the spray water tank 9 can be placed at a suitable position on the load-bearing plate 1, and the limit block 5 and the limit pin 6 are reset to prevent the spray water tank 9 from moving a lot when the load-bearing plate 1 moves. Before the spray water tank 9 is filled with water, the two threaded sleeves 8 are respectively rotated around the two threaded rods 7, and the two threaded sleeves 8 respectively drive the two anti-skid pads 20 to descend along the two threaded rods 7 until the two anti-skid pads 20 contact the ground. After the spray water tank 9 is filled with water, it can play a certain load-bearing function, reduce the pressure of the four load-bearing wheels 2, and extend the service life of the four load-bearing wheels 2.

[0026] Specifically, when the operator disassembles and assembles the spray water tank 9, he pulls out the limit pin 6, and then removes the limit block 5 along the slide groove 4. Then, the spray water tank 9 can be placed at a suitable position on the load-bearing plate 1, and the limit block 5 and the limit pin 6 can be reset to prevent the spray water tank 9 from moving a lot when the load-bearing plate 1 moves, causing the spray water tank 9 to fall off the load-bearing plate 1. Pushing the auxiliary handle 3 can drive the load-bearing plate 1 to move through the four load-bearing wheels 2. Before the spray water tank 9 is filled with water, the two threaded sleeves 8 are respectively rotated around the two threaded rods 7. The two threaded sleeves 8 respectively drive the two anti-skid pads 20 to descend along the two threaded rods 7 until the two anti-skid pads 20 contact the ground. After the spray water tank 9 is filled with water, it can play a certain load-bearing function, reduce the pressure of the four load-bearing wheels 2, and extend the service life of the four load-bearing wheels 2.

[0028] See also Figure 4 The stirring structure includes: a stirring shaft 17, a plurality of stirring paddles 18 and a plurality of auxiliary paddles 19; the stirring shaft 17 is connected to the inside of the spray water tank 9, the plurality of stirring paddles 18 are respectively installed on the outer wall surface of the stirring shaft 17, and the plurality of auxiliary paddles 19 are respectively installed on the outer wall surface of the stirring shaft 17.

[0029] See also Figure 4 Two liquid level detectors 21 are installed on the inner wall of the spray water tank 9 and are arranged in upper and lower positions. In this embodiment, when the upper liquid level detector 21 detects water, the warning light on the auxiliary tank cover 11 lights up, and the operator stops pouring the cleaning mixture.

[0030] See also Figure 4 The spray water tank 9 and the auxiliary tank cover 11 are respectively provided with guide holes 22. In this embodiment, the two guide holes 22 are staggered to prevent the cleaning mixed liquid from splashing during stirring.

[0031] In this embodiment, two guide holes 22 are offset to prevent the cleaning mixture from splashing during stirring. When the upper liquid level detector 21 detects water, the warning light on the auxiliary tank cover 11 lights up. At this time, the operator stops pouring the cleaning mixture, and then starts the stirring shaft 17. The stirring shaft 17 drives a number of stirring paddles 18 and a number of auxiliary paddles 19 to rotate to stir the cleaning mixture. Then, the pressure pump 14 is started, and the cleaning mixture is sprayed along the pressurized nozzle 16 to spray the cleaning mixture onto the photovoltaic panel. As the spraying continues, the cleaning mixture inside the spray water tank 9 gradually decreases. When the lower liquid level detector 21 detects no water, the pressure pump 14 and the stirring shaft 17 are automatically turned off.

[0032] Specifically, before the operator fills the spray water tank 9 with water, he holds the two tank cover positioning plates 12, rotates the auxiliary tank cover 11 around the spray water tank 9, and aligns the two diversion holes 22.

At this time, the auxiliary tank cover 11 cannot rotate around the spray water tank 9. Then the operator fills water and cleaning agent along the diversion holes 22. After the introduction is completed, the positioning holes opened in the other set of water tank positioning plates 10 and the tank cover positioning plate 12 are aligned in the above manner, and the positioning pin 13 is inserted to make the two guide holes 22 aligned. The flow holes 22 are misaligned to prevent splashing during stirring. When the upper liquid level detector 21 detects water, the warning light on the auxiliary tank cover 11 lights up. At this time, the operator stops pouring the cleaning mixture, and then starts the stirring shaft 17. The stirring shaft 17 drives a number of stirring paddles 18 and a number of auxiliary paddles 19 to rotate to stir the cleaning mixture. Then the pressure pump 14 is started, and the cleaning mixture is sprayed along the pressurized nozzle 16 to spray the cleaning mixture onto the photovoltaic panel. As the spraying continues, the cleaning mixture inside the spray water tank 9 gradually decreases. When the lower liquid level detector 21 detects no water, the pressure pump 14 and the stirring shaft 17 are automatically closed.
