[0034] Preferably, the cleaning device includes a plurality of first cleaning mechanisms 200 and a plurality of second cleaning mechanisms 300 arranged side by side.

[0035] Combination Figure 1 The embodiment of the utility model selects a combination of two first cleaning mechanisms 200 + two second cleaning mechanisms 300. Considering that the cleaning device relies on a stick brush and a wiping member for cleaning, the selection of multiple mechanisms can increase the cleaning effect.

[0036] Preferably, the two second cleaning mechanisms 300 are arranged side by side and are both located between the two first cleaning mechanisms 200 .

[0037] Optionally, two first cleaning mechanisms 200 are arranged side by side and are both located between two second cleaning mechanisms 300 .

[0038] The above two preferred solutions can realize the effect of simulating manual cleaning in two mutually perpendicular directions of the utility model, combined with Figure 1 and Figure 2 As shown, in the embodiment of the present invention, two second cleaning mechanisms 300 are located between two first cleaning mechanisms 200 .

[0039] Preferably, the first cleaning mechanism 200 includes a stick brush 201, an adjustable speed motor 203 and a synchronous belt 202, and the axis of the stick brush 201 is perpendicular to the forward direction of the frame 100 in the solar photovoltaic panel.

[0040] Preferably, the first cleaning mechanism 200 includes two parallel stick brushes 201, and the first cleaning mechanism 200 also includes an adjustable speed motor 203 and a synchronous belt 202; the two stick brushes 201 are connected to the synchronous belt 202, and the synchronous belt 202 is connected to the adjustable speed motor 203, and the adjustable speed motor 203 transmits power to enable the two stick brushes 201 to rotate synchronously.

[0041] In the utility model embodiment of the present application, the first cleaning mechanism 200 includes two parallel stick brushes 201, which can increase the cleaning effect of the cleaning device by increasing the contact area between the stick brush 201 and the photovoltaic panel to be cleaned, and the two stick brushes 201 are connected by a synchronous belt 202 to achieve synchronous rotation, which can ensure that the two stick brushes 201 are wiped in one direction when the adjustable speed motor 203 works, and there will be no mutual interference resulting in a deterioration of the cleaning effect.

[0042] Preferably, the second cleaning mechanism 300 includes a wiping member and an actuating member, and the actuating member can drive the wiping member to move back and forth and wipe along a longitudinal direction parallel to the forward direction of the frame 100 in the solar photovoltaic panel.

Considering that the second cleaning mechanism 300 in this embodiment is provided with multiple guide rails 304 and screws 303, the use of the through-type screw motor 301 has the advantages of allowing a larger system installation error and saving installation space, which can reduce the probability of poor cleaning effect of the card base 302 due to installation errors of the screw 303 and the guide rail 304.

[0046] Preferably, the cleaning device also includes a water spray mechanism 400, which is connected to the frame 100 and is arranged side by side with the first cleaning mechanism 200 and the second cleaning mechanism 300; the water spray mechanism 400 includes a cleaning pipeline 401, and the cleaning pipeline 401 has a plurality of nozzles 402, and the nozzles 402 can spray cleaning liquid onto the stick brush 201 of the first cleaning mechanism 200, and can spray cleaning liquid onto the cardboard base 302 of the second cleaning mechanism 300.

The stick brush 201 here wipes the photovoltaic panel to be cleaned without cleaning liquid, completing the step of wiping off the cleaning liquid left by the cleaning in the above two directions; after cleaning is completed, the cleaning device is away from the photovoltaic panel, and the nozzle 402 now injects water into the stick brushes 201 of the two first cleaning mechanisms 200, and adjusts the rotation speed of the adjustable speed motor 203 to make the stick brush 201 rotate at high speed.

When the conditions for the normal operation of the cleaning device are not met, the staff can be reminded to prevent misoperation or damage to the photovoltaic panel.

[0052] In summary, the utility model provides a cleaning device for a solar photovoltaic panel, wherein the cleaning device comprises a frame, a first cleaning mechanism, a second cleaning mechanism and a water spraying mechanism.
