[0002] In the current clean energy field, photovoltaic technology has been widely used as an important source of renewable energy. However, the pollution problem on the surface of photovoltaic panels has attracted increasing attention, especially dust pollution, which can seriously reduce the performance and efficiency of solar cells. Dust pollution on the surface of photovoltaic panels is mainly caused by pollutants such as suspended particles, fine dust, and dust in the air. It accumulates on the surface of photovoltaic panels, blocks sunlight, and reduces the power generation efficiency of the battery.

[0003] By spraying an anti-dust pollution coating on the surface of photovoltaic panels, the adverse effects of dust pollution on the performance of photovoltaic panels can be effectively reduced, the energy output of the photovoltaic system can be improved, the frequency of cleaning and maintenance can be reduced, and the operating costs of the photovoltaic system can be reduced.

[0004] At present, spraying paint is mostly done manually, which is labor-intensive, risky, and inefficient. In addition, paint droplets are harmful to the health of sprayers, and long-term exterior wall spraying may cause respiratory occupational diseases.

Through such a setting, remote spraying of the drone can be realized, and the operators can be kept away from the paint droplets when spraying the paint to avoid endangering the health of the operators, while improving the spraying efficiency.

[0061] Further optimizing the scheme, gas cylinder 3 includes:

[0067] The second partition plate 304 is fixedly connected to the inner wall of the gas cylinder wall 301, and a second exhaust portion is provided on the second partition plate 304, and the second exhaust portion is used for unidirectionally exhausting the gas in the third gas cavity 315 into the fourth gas cavity 311;

[0068] The first piston 303 is slidably connected in the cylinder wall 301, and the first piston 303 is transmission-connected with a reciprocating moving part;

[0069] A first air intake check valve 306 is embedded in the bottom of the second air cavity 309. The air intake end of the first air intake check valve 306 is connected to the outside, and the air exhaust end of the first air intake check valve 306 is connected to the inside of the second air cavity 309.

[0070] A second air intake check valve 313 is embedded in the bottom of the third air cavity 315, the air intake end of the second air intake check valve 313 is communicated with the outside, and the exhaust end of the second air intake check valve 313 is communicated with the inside of the third air cavity 315;

[0071] The first piston 303 is located between the first intake check valve 306 and the second intake check valve 313 .

[0072] According to a further optimization scheme, the first exhaust part includes a plurality of first exhaust one-way valves 307, and the plurality of first exhaust one-way valves 307 are embedded on the first partition plate 302 at equal intervals around the circumference, the air inlet end of the first exhaust one-way valve 307 is connected to the second air cavity 309, and the air outlet end of the first exhaust one-way valve 307 is connected to the first air cavity 308.

One end of the bidirectional threaded rod 316 is axially connected to the first motor 312, and the first motor 312 is fixedly connected to the second partition plate 304. The first motor 312 is located in the fourth air chamber 311.

[0075] When in use, the first motor 312 drives the bidirectional threaded rod 316 to rotate, so that the first piston 303 can slide back and forth in the cylinder wall 301 .

[0076] A first slider 305 is fixedly connected to the first piston 303, and the first slider 305 is slidably connected to the first slide 310. The first slide 310 is opened on the inner wall of the gas cylinder wall 301 and is located between the first air intake check valve 306 and the second air intake check valve 313, which can prevent the first piston 303 from rotating together with the two-way threaded rod 316.

[0077] When the first piston 303 moves to the left, air is sucked into the third air cavity 315 through the second air intake check valve 313. At the same time, the first air intake check valve 306 prevents the air in the second air cavity 309 from being discharged, so that the air in the second air cavity 309 enters the first air cavity 308 through the first exhaust check valve 307, and then enters the spray pot 4 from the first air cavity 308 to squeeze out the paint raw materials.

[0078] When the first piston 303 moves to the right, the second air chamber 309 is inflated through the first air intake check valve 306, and at the same time the second air intake check valve 313 prevents the air in the third air chamber 315 from being discharged, so that the air in the third air chamber 315 enters the fourth air chamber 311 through the second air exhaust check valve 314, and the air in the fourth air chamber 311 enters the air pressure sensor 9, which can feedback the air pressure in the fourth air chamber 311, and then control the gas discharge speed through the adjustable flow solenoid valve 11, thereby controlling the injection pressure of the nozzle 1.

[0079] Further optimizing the scheme, the spray pot 4 includes:

[0080] The spray pot wall 401 is fixedly connected to the mounting frame;

[0081] The third partition plate 404 is horizontally fixed in the spray pot wall 401, and the third partition plate 404 divides the spray pot wall 401 into a liquid inlet cavity 402 and a liquid outlet cavity which are distributed vertically. A liquid inlet check valve 405 is embedded in one end of the third partition plate 404, and the liquid inlet end of the liquid inlet check valve 405 is connected to the liquid inlet cavity 402, and the liquid outlet end of the liquid inlet check valve 405 is connected to the liquid outlet cavity;

[0082] A filter unit, disposed in the liquid inlet cavity 402;

[0083] The second piston 408 is slidably connected in the liquid outlet chamber. The second piston 408 divides the liquid outlet chamber into an air inlet chamber 412 and a liquid discharge chamber 413. The liquid discharge chamber 413 is connected to the liquid inlet chamber 402 through the liquid inlet check valve 405. The air inlet chamber 412 is connected to the first air chamber 308 through the third air inlet check valve 410. The third air inlet check valve 410 is used for the air in the first air chamber 308 to enter the air inlet chamber 412 in one direction. The liquid outlet end of the liquid discharge chamber 413 is connected to the liquid inlet end of the nozzle 1 through the liquid discharge check valve 414.

[0084] The elastic part is disposed in the liquid discharge chamber 413, one end of the elastic part is fixedly connected to one side of the second piston 408, and the other end of the elastic part is fixedly connected to the inner wall of the liquid discharge chamber 413;

[0085] The solenoid valve 411 is embedded in the bottom of the spray pot wall 401. The solenoid valve 411 is connected to the air inlet chamber 412. The solenoid valve 411 is used to control the exhaust of the air inlet chamber 412. The solenoid valve 411 is electrically connected to the power supply control unit.

[0086] According to a further optimized solution, the elastic part includes a spring 406 , one end of the spring 406 is fixedly connected to one side of the second piston 408 , and the other end of the spring 406 is fixedly connected to the inner wall of the discharge chamber 413 .

[0088] A second slider 409 is fixedly connected to the edge of the second piston 408, and the second slider 409 is slidably connected to the second slideway 407. The second slideway 407 is provided on the inner wall of the spray pot wall 401 to prevent the second piston 408 from rotating.

[0089] The liquid outlet of the liquid discharge chamber 413 is connected to a liquid discharge check valve 414 , the liquid inlet of the liquid discharge check valve 414 is connected to the liquid outlet of the liquid discharge chamber 413 , and the liquid outlet of the liquid discharge check valve 414 is connected to the liquid inlet of the nozzle 1 .

[0090] During use, in the initial state, the air in the first air cavity 308 enters the air inlet cavity 412 through the third air inlet check valve 410. Since the third air inlet check valve 410 cannot exhaust air, the solenoid valve 411 is also in a closed state at this time. Under the action of air pressure, the second piston 408 can be pushed and the spring 406 can be squeezed. When the spring 406 is shortened to the limit, the feed port opened at the top of the spray bottle wall 401 is opened to fill the liquid inlet cavity 402 with paint, and then the feed port is closed. At this time, the solenoid valve 411 is opened, the air inlet cavity 412 is exhausted, and the spring 406 restores its length to push the second piston 408 to move. At the same time, the paint in the liquid inlet cavity 402 is sucked into the liquid discharge cavity 413 through the liquid inlet check valve 405. Then the solenoid valve 411 is closed. As the air inlet cavity 412 is filled with gas again, when the second piston 408 is pushed, the paint in the liquid discharge cavity 413 is transported to the nozzle 1 through the liquid discharge check valve 414 for spraying.

[0091] To further optimize the solution, the power supply control unit includes:

[0092] Indicator light 5, fixed on the mounting frame;

[0096] Embodiment 2:

[0097] refer to Figure 4 The difference between this embodiment and embodiment 1 is that the liquid outlet end of the liquid discharge check valve 414 is connected to the liquid inlet end of the hydraulic regulator 10, and the liquid outlet end of the hydraulic regulator 10 is connected to the nozzle 1.

[0098] The hydraulic regulator 10 includes a liquid storage cylinder 1001, in which a third piston 1003 is vertically slidably connected, a threaded rod 1004 is threadedly connected to the middle part of the third piston 1003, the threaded rod 1004 is rotatably connected in the liquid storage cylinder 1001, the top end of the threaded rod 1004 is axially connected to the output shaft of the second motor 1002, the fixed end of the second motor 1002 is fixedly connected to the top outer side of the liquid storage cylinder 1001, one side of the bottom of the liquid storage cylinder 1001 is connected to the liquid outlet end of the discharge one-way valve 414, and the other side of the bottom of the liquid storage cylinder 1001 is connected to the nozzle 1.

[0099] When the air pressure in the air inlet chamber 412 continues to increase, the liquid inlet pressure will continue to increase, resulting in inaccurate liquid spraying amount. At this time, the second motor 1002 can drive the threaded rod 1004 to rotate to move the third piston 1003 upward, thereby increasing the volume of the liquid storage cylinder 1001 and reducing the hydraulic pressure entering the nozzle 1.
