[0030] like Figure 1 to Figure 2 As shown, the photovoltaic panel dust cleaning robot of the utility model comprises:

[0031] A robot body 1 is provided with a brush 3 for cleaning dust via a support frame 2; a partition 4 is arranged in the robot body 1 and divides the robot body 1 into a closed chamber 5, wherein a filter air outlet is provided on the robot body 1, and the filter air outlet is used to connect the outside of the robot body 1 with the closed chamber 5; a dust removal box 7 is arranged in the closed chamber 5, and the dust removal box 7 has an air inlet 81 and an air outlet 82, and dust removal liquid 9 for gathering impurities is contained in the dust removal box 7; a fan 10 is installed on the side wall of the dust removal box 7, and the fan 10 is directly opposite to the air outlet 82.

[0032] See also Figure 1 , Figure 2 The closed chamber 5 formed by the partition 4 in the robot body 1 is used to place the dust removal box 7. The robot body 1 can be provided with a filter air outlet on the side, bottom or top of the closed chamber. The filter air outlet and the air inlet 81 and the air outlet 82 set on the dust removal box 7 form a complete air path.

[0033] It should be noted that the dust absorbing liquid 9 in the dust removal box 7 is located below the air inlet 81 and the air outlet 82 to prevent the dust absorbing liquid 9 from leaking through the air inlet 81 and the air outlet 82. The dust absorbing liquid 9 can be water or oil.

[0034] During operation, the device arranged on the robot body 1 can drive the brush 3 to rotate. When the robot body 1 moves on the photovoltaic panel, the rotating brush 3 can clean the dust on the photovoltaic panel. At the same time, the fan 10 is turned on. The fan 10 sucks the dust cleaned by the external brush 3 into the dust removal box 7 through the air inlet 81 of the dust removal box 7, and discharges it to the closed chamber through the air outlet 82, and finally discharges it to the outside of the robot body 1 through the filter air port. After the dust enters the dust removal box 7, the dust is adsorbed by the dust absorption liquid 9, so that the airflow discharged to the outside through the filter air port contains only a small amount of dust, which effectively improves the cleaning effect of the device on the photovoltaic panel, avoids the dust phenomenon, and has practicality.

[0035] In one or more embodiments, a sealing component is installed in the dust removal box 7 above the dust absorption liquid 9 , and the sealing component is used to seal the oil at the bottom of the dust removal box 7 .

[0036] The sealing component includes: a rubber corrugated plate 11, which is horizontally arranged on the inner wall of the dust removal box 7, and an ear plate 12 is installed on the top of the rubber corrugated plate 11; a screw 13, which is rotatably installed on the dust removal box 7, and the screw 13 passes through the ear plate 12 and cooperates with its thread; a servo motor, whose rotating shaft end is connected to the screw 13.

[0037] The servo motor is not shown in the accompanying drawings. The servo motor is mounted on the outer side wall of the dust removal box 7; see the attached Figure 2 The rubber corrugated plate 11 is horizontally installed on the inner wall of the dust removal box 7. One end of the rubber corrugated plate 11 is fixedly connected to the inner wall of the dust removal box 7, and an ear plate 12 is installed on the top surface of the other end. By controlling the movement of the ear plate 12, the rubber corrugated plate 11 can seal the dust collection liquid 9 in the dust removal box 7, thereby reducing the problem of leakage of the dust collection liquid 9 during the transportation process of the robot body 1.

[0038] During operation, the screw 13 is controlled to rotate by the servo motor, so that the ear plate 12 connected to the screw 13 threadably drives one end of the rubber corrugated plate 11 to move horizontally to cover the space in the dust removal box 7 for the dust collecting liquid 9, thereby sealing the dust collecting liquid 9. The operation is convenient, the structure is simple, and it is practical.

[0039] In one or more embodiments, a guide pipe 14 is installed on the support frame 2 , a wind hole is opened on the side of the guide pipe 14 , and the guide pipe 14 is connected to the air inlet 81 through a pipeline.

[0040] See also Figure 1 , Figure 2The guide tube 14 is mounted on the support frame 2 by bolts, and the positions of the guide tube 14 and the brush 3 are adapted so that the negative pressure generated in the guide tube 14 can absorb more dust raised by the brush 3.

[0041] In one or more embodiments, the dust removal box 7 is provided with a suspension ball 15 on the surface of the dust absorbing liquid 9 .

[0042] See also Figure 2 The suspension ball 15 arranged on the surface of the dust-absorbing liquid 9 can effectively prevent the dust-absorbing liquid 9 from flowing out of the dust-absorbing box 7 through the air inlet 81 or the air outlet 82 due to the shaking of the robot body 1, thereby ensuring that the liquid level of the dust-absorbing liquid 9 is within the threshold range; at the same time, after the airflow containing dust enters the dust-absorbing box 7 through the air inlet 81, the airflow blows the suspension ball 15 to rotate, so that the dust-absorbing liquid 9 always fluctuates, thereby further improving the adsorption effect of the dust-absorbing liquid 9 on the dust in the airflow.

[0043] In one or more embodiments, the suspension ball 15 is connected to the bottom of the dust removal box 7 via an elastic member 16 .

[0044] See also Figure 2 This arrangement can prevent the suspension ball 15 from being separated from the dust absorbing liquid 9, so that the dust absorbing liquid 9 can remain stable under the action of the suspension ball 15, thereby ensuring that the dust absorbing liquid 9 continues to absorb dust.

[0045] In one or more embodiments, the elastic member 16 is a spring or an elastic cord.

[0046] In one or more embodiments, a baffle 17 is installed in the dust removal box 7 between the air inlet 81 and the air outlet 82 .

[0047] See also Figure 2 The baffle 17 can transport the airflow adsorbed by the air inlet 81 toward the dust-absorbing liquid 9, thereby improving the adsorption effect of the device on dust in the inhaled airflow.

[0048] In one or more embodiments, a first filter is installed in the air outlet 82. This arrangement can further improve the absorption of dust generated when the brush 3 rotates.

[0049] In one or more embodiments, a second filter is installed at the filter air outlet. This arrangement can further improve the dust removal of the present application and ensure the dust removal effect of the present application.

[0050] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
