[0061] Dust and dirt on the surface of photovoltaic panels will not only block sunlight and reduce the conversion rate of light energy, but may also cause problems such as hot spots, further damaging the service life of the panels.

[0062] The current lack of dedicated dust removal tools on the market forces maintenance teams to rely on manual cleaning, a labor-intensive and inefficient process with often unsatisfactory results. To improve the power generation efficiency of photovoltaic panels, there is an urgent need to develop efficient and environmentally friendly dust removal solutions, such as automated cleaning equipment, to reduce the labor burden and improve overall operational efficiency.

[0063] In view of this, if Figure 1 As shown, this solution provides a photovoltaic panel dust removal device to alleviate the above problems. The device includes a spray component 100, a cleaning component 200 and a wastewater recovery component 300;

[0064] The water spray port 111 of the spray assembly 100 faces the surface of the photovoltaic panel 400;

[0065] The cleaning component 200 can clean the dust on the surface of the photovoltaic panel 400;

[0066] The wastewater recovery assembly 300 can collect wastewater flowing out along the photovoltaic panel 400 .

[0067] This device can realize automatic dust removal of photovoltaic panels 400 and collection and recycling of wastewater and rainwater. Through automatic control, it coordinates the operation of the spray component 100, the cleaning component 200 and the wastewater recovery component 300, thereby improving the cleaning effect of the photovoltaic panels 400, improving the power generation efficiency and reducing the labor intensity of workers.

[0068] Regarding the shape and structure of the spray assembly 100, Figure 1 As shown:

[0069] The spray assembly 100 includes a spray pipe 110, a water pump 120 and a water tank 130;

[0070] The spray pipe 110 is provided on the upper portion of the photovoltaic panel 400;

[0071] The water tank 130 is disposed below the photovoltaic panel 400;

[0072] One end of the water pump 120 is connected to the spray pipe 110, and the other end is connected to the water tank 130;

[0073] The spray pipe 110 is provided with multiple groups of water spray ports 111 along the length direction of the photovoltaic panel 400.

[0074] Specifically, the pipeline of the spray assembly 100 is set below and behind the photovoltaic panel 400, and the installation height of the spray pipe 110 is higher than the height of the photovoltaic panel 400 so that the water sprayed by the spray pipe 110 can fully infiltrate the surface of the photovoltaic panel 400.

[0075] Regarding the shape and structure of the cleaning component 200, as shown in FIG. Figure 1 As shown:

[0076] The cleaning assembly 200 includes a driving motor 210, a dust removal roller brush 220 and a guide shaft 230;

[0077] The output end of the driving motor 210 is gear-connected to the guide shaft 230;

[0079] The dust removal roller brushes 220 are respectively arranged on both sides of the guide shaft 230 and are threadedly connected to the guide shaft 230;

[0080] The bristles of the dust removal roller brush 220 abut against the upper surface of the photovoltaic panel 400;

[0081] The driving motor 210 can control the rotation of the guide shaft 230 and drive the dust removal roller brush 220 to reciprocate along the length direction of the photovoltaic panel 400.

[0082] Specifically, after the two groups of dust removal roller brushes 220 are fixedly connected by a nut seat, the nut seat is threadedly connected to the guide shaft 230, and the rotational motion of the guide shaft 230 is converted into linear motion of the dust removal roller brush 220 through the screw-nut seat structure. More preferably, the upper and lower ends of the photovoltaic panel 400 can also be provided with guide grooves connected to the dust removal roller brush 220, so that the movement trajectory of the dust removal roller brush 220 is more stable, thereby improving the cleaning effect of the dust removal roller brush 220.

[0083] Regarding the shape and structure of the wastewater recovery assembly 300, as shown in FIG. Figure 1 As shown:

[0084] The wastewater recovery assembly 300 includes a sump 310 and a wastewater collection tank 320;

[0089] Specifically, the water collection tank 310 is inclined toward the wastewater collection tank 320 and has a drain port connected to the wastewater collection tank 320 to facilitate the recovery of waste liquid. In addition, since the waste liquid contains a large amount of dust and dirt on the photovoltaic panel 400, a first filter 330 is set at the bottom of the wastewater collection tank 320 to filter the waste water so that the recovered waste water can be reused to save water, and a second filter 340 is also set at the water outlet of the water tank to prevent dust and dirt from entering the spray assembly 100 and causing secondary pollution to the greatest extent.

[0090] The device also includes a control system 500;

[0091] The control system 500 includes a proximity sensor 510, a liquid level sensor 520, a temperature sensor 530, a limit switch 540, a solenoid valve, and a control cabinet 560;

[0092] The proximity sensors 510 are arranged at the four corners of the upper surface of the photovoltaic panel 400 and are capable of detecting the position of the dust removal roller brush 220;

[0093] The liquid level sensor 520 is provided inside the water tank 130 and can detect the liquid level height in the water tank 130; and can monitor in real time during cleaning, and can alarm and stop the dust removal operation when the water level falls below the set lower limit;

[0094] The temperature sensor 530 is provided outside the water tank 130 and is capable of detecting the ambient temperature;

[0095] The limit switches 540 are provided at both ends of the guide shaft 230 and can limit the operating range of the dust removal roller brush 220;

[0097] The first solenoid valve 551 is provided at the water outlet of the water tank 130;

[0098] The second solenoid valve 552 is disposed in the pipe between the water pump 120 and the spray pipe 110;

[0099] The third solenoid valve 553 is provided at the drain outlet of the water tank 130;

[0100] The fourth solenoid valve 554 is provided at the water inlet of the water tank 130;

[0101] The control cabinet 560 is electrically connected to the proximity sensor 510 , the liquid level sensor 520 , the temperature sensor 530 , the limit switch 540 and the solenoid valve respectively.

[0102] Specifically, the proximity sensor 510, liquid level sensor 520, temperature sensor 530, limit switch 540 and solenoid valve in the accompanying drawings are represented in the form of boxes, which does not affect the understanding of those skilled in the art, and the control cabinet 560 can be connected to the network to promptly feed back relevant information to the monitoring terminal. At the same time, the monitoring terminal can also remotely control the control cabinet 560 to perform related operations.

[0103] The working principle of this device is:

[0104] The control system 500 includes cleaning action, antifreeze action and drainage action;

The limit switch 540 cooperates with the proximity sensor 510 to detect the position of the dust removal roller brush 220 and control the reciprocating motion of the dust removal roller brush 220.

[0106] In the antifreeze action, after the temperature sensor 530 detects that the ambient temperature is lower than the preset value, it controls the fourth solenoid valve 554 to close, and controls the first solenoid valve 551 and the third solenoid valve 553 to be turned on, thereby draining the water in the water tank 130;

[0107] During drainage, the liquid level sensor 520 detects that the liquid level in the water tank 130 reaches a specified height, controls the first solenoid valve 551 and the third solenoid valve 553 to be turned on, and the fourth solenoid valve 554 to be closed, thereby discharging the water in the water tank 130 to the lower part of the specified height.

[0108] Specifically, the cleaning action, antifreeze action and drainage action of the control system 500 can be adjusted by adjusting relevant parameters in the control cabinet 560 or the monitoring terminal, such as the preset ambient temperature value, the working frequency of the cleaning action, etc.

[0109] The control cabinet 560 is provided with a control button that can switch the control system 500 between the automatic mode and the manual mode.
