The vertically arranged crawler and limiting wheels in the walking component ensure the installation accuracy, and can be applied to photovoltaic panels with different inclination angles. Through the cooperation of the fixed support and the rotating support, it can be realized to walk on the uneven array of photovoltaic panels. Through the ultrasonic transducer in the ultrasonic dust removal component, the dust accumulated on the edges and corners of the photovoltaic panel can be removed, and point-to-point cleaning can be achieved for the stubborn dust that cannot be cleaned by the roller brush, thereby improving the cleaning ability and cleaning efficiency without damaging the surface of the photovoltaic panel.

The cleaning adjustment frame 3 is equipped with a driving assembly, and the driving assembly is used to simultaneously drive the cleaning movable roller 5 and the cleaning fixed roller 6 to rotate.

[0029] When it is necessary to clean photovoltaic panels of different lengths and inclinations, first adjust the length and inclination of the cleaning adjustment frame 3 through the adjustment mechanism so that the cleaning adjustment frame 3 is parallel to the surface of the photovoltaic panel. Then, the mobile lifting frame 1 is raised and lowered so that the cleaning roller 5 and the cleaning fixed roller 6 are in contact with the surface of the photovoltaic panel. When the driving wheel 2 is started, the driving wheel 2 drives the mobile lifting frame 1 to move along the laying direction of the photovoltaic panel, and the mobile lifting frame 1 drives the cleaning adjustment frame 3 to move along the laying direction of the photovoltaic panel. When the driving assembly drives the cleaning roller 5 and the cleaning fixed roller 6 to rotate at the same time, the cleaning roller 5 and the cleaning fixed roller 6 jointly clean the dust on the surface of the photovoltaic panel.

[0030] See also Figure 1-Figure 3In order to facilitate the cleaning and adjusting frame 3 to adapt to photovoltaic panels of different lengths, the cleaning and adjusting frame 3 includes a fixed portion 7 and a sliding portion 8. A slide groove 9 is provided at one end of the fixed portion 7, and the sliding portion 8 is slidably installed in the slide groove 9, and the sliding portion 8 extends outside one end of the fixed portion 7. The inner top wall of the mobile lifting frame 1 is fixedly connected with a vertical rod 10, and the vertical rod 10 is hinged to one end of the top surface of the fixed portion 7. The cleaning fixed roller 6 is rotatably installed in the fixed portion 7, and the cleaning movable roller 5 is rotatably installed in the sliding portion 8, and the cleaning fixed roller 6 and the cleaning movable roller 5 are staggered.

[0031] For details, see Figure 1 The adjusting mechanism is used to drive the sliding part 8 to slide and swing, and the adjusting mechanism includes a cylinder 11, which is slidably installed on the inner top wall of the mobile lifting frame 1, and the telescopic end of the cylinder 11 is hinged to the top surface of the sliding part 8.

[0032] See also Figure 1 In order to facilitate the cylinder 11 to slide along the length direction of the mobile lifting frame 1, the mobile lifting frame 1 is equipped with a moving assembly, and the moving assembly includes a first motor 12 and a screw rod 13. A moving groove 14 is provided on the inner top wall of the mobile lifting frame 1, and the screw rod 13 is rotatably installed in the moving groove 14.

The first motor 12 is fixedly installed on one side of the mobile lifting frame 1, and the driving shaft of the first motor 12 extends into the moving groove 14, and the driving shaft of the first motor 12 is coaxially fixedly connected with the screw rod 13.

[0033] When the first motor 12 is started, the driving shaft of the first motor 12 drives the screw rod 13 to rotate. Under the guidance of the moving groove 14, the screw rod 13 drives the moving block 15 to slide along the opening direction of the moving groove 14. The moving block 15 drives the cylinder 11 to slide along the opening direction of the moving groove 14. The cylinder 11 then drives the sliding part 8 to slide relative to the fixed part 7. Finally, the cleaning and adjusting frame 3 is extended or shortened, and the telescopic adjustment of the cleaning and adjusting frame 3 is completed.

[0034] When the cylinder 11 is started, the telescopic end of the cylinder 11 drives the sliding part 8 to swing, and the sliding part 8 drives the fixed part 7 to swing. At this time, the fixed part 7 swings with the hinge point between the vertical rod 10 and the fixed part 7 as the center, and finally the inclination angle of the cleaning adjustment frame 3 is equal to the inclination angle of the photovoltaic panel, so that the cleaning fixed roller 6 and the cleaning movable roller 5 can clean the surface of the photovoltaic panel together.

[0035] See also Figure 3-Figure 5In order to ensure that the cleaning roller 5 and the cleaning fixed roller 6 rotate and clean at the same time when the sliding part 8 and the fixed part 7 move relative to each other, a fixing seat 16 is fixedly connected to the inner wall of the fixed part 7, a rotating sleeve 17 is rotatably installed in the fixing seat 16, and the cleaning roller 5 is plugged into the rotating sleeve 17. A guide bar 18 is fixedly connected to the inner wall of the rotating sleeve 17, and the number of the guide bars 18 is set, and the plurality of guide bars 18 are distributed in a circular array around the axis of the rotating sleeve 17. A guide groove 19 is opened on the side wall of the cleaning roller 5 at the position corresponding to the guide bar 18, and the guide bar 18 is plugged into the guide groove 19.

[0036] Therefore, when the sliding portion 8 slides relative to the fixed portion 7 , the sliding portion 8 drives the cleaning roller 5 to slide relative to the fixed portion 7 , and under the guidance of the guide bar 18 and the guide groove 19 , the cleaning roller 5 slides relative to the rotating sleeve 17 .

[0037] For details, see Figure 2 and Figure 3 The driving assembly includes a second motor 20 and a first transmission chain 21. A first gear 22 is fixedly sleeved on the outer wall of one end of the rotating sleeve 17. A second gear 23 is fixedly sleeved on one end of the cleaning fixed roller 6 close to the sliding part 8. A third gear 24 is rotatably mounted on the top surface of the fixed part 7, and the first gear 22, the second gear 23 and the third gear 24 are meshed through the transmission of the first transmission chain 21. The second motor 20 is fixed to the top surface of the fixed part 7, and the driving shaft of the second motor 20 is coaxially fixedly connected with the third gear 24. In addition, a clearance groove 25 is provided on the top surface of the sliding part 8, and the first transmission chain 21 is slidably connected to the clearance groove 25.

[0038] When the second motor 20 is started, the driving shaft of the second motor 20 drives the third gear 24 to rotate, and the third gear 24 drives the second gear 23 and the first gear 22 to rotate through the first transmission chain 21. The first gear 22 and the second gear 23 respectively drive the cleaning movable roller 5 and the cleaning fixed roller 6 to rotate in the same direction.

[0039] See also Figure 2 In order to collect the dust swept by the fixed roller 6 and the moving roller 5, the end of the sliding part 8 away from the fixed part 7 is fixedly connected with a dust cover 26, one end of the dust cover 26 is fixedly connected with a dust pipe 27, and one end of the dust pipe 27 is fixedly connected with a dust collecting member (not shown in the figure). In this embodiment, the dust collecting member is a dust pump, and the dust pump is installed on the mobile lifting frame 1.

[0040] When the dust collecting member is started, the dust cleaned by the fixed cleaning roller 6 and the movable cleaning roller 5 is first sucked into the dust collecting cover 26, and then sucked into the dust collecting pipe 27, and finally collected in the dust collecting member.

[0041] It is worth mentioning that see Figure 3In order to blow the dust toward the suction hood, the fixed portion 7 is installed with a dust blowing assembly, which includes a dust blowing fan 28. There are two dust blowing fans 28, which are fixedly installed in parallel on the inner wall of the fixed portion 7, and the two dust blowing fans 28 are located above the cleaning fixed roller 6 and the cleaning movable roller 5.

[0042] See also Figure 3 In order to make the two dust blowing fans 28 rotate and blow dust at the same time, the fixed part 7 is equipped with a transmission assembly, and the transmission assembly includes a second transmission chain 29. One end of the two dust blowing fans 28 is coaxially fixedly connected with a fourth gear 30, and the top surface of the fixed part 7 is rotatably installed with a fifth gear 31, and a connecting shaft 32 is coaxially fixedly connected between the fifth gear 31 and the third gear 24. The fourth gear 30 and the fifth gear 31 are meshed through the second transmission chain 29.

[0043] When the second motor 20 is started, the second motor 20 coaxially drives the connecting shaft 32 to rotate, the connecting shaft 32 drives the fifth gear 31 to rotate, and the fifth gear 31 simultaneously drives the fourth gear 30 to rotate in the same direction through the second transmission chain 29. The two fourth gears 30 respectively drive the corresponding dust blowing fans 28 to rotate. At this time, the dust blowing fans 28 blow the dust toward the direction close to the dust hood 26.

[0044] Working principle of a photovoltaic panel cleaning robot: In the initial state, the cleaning adjustment frame 3 is arranged horizontally. When it is necessary to clean photovoltaic panels of different lengths, the first motor 12 is started first, the driving shaft of the first motor 12 drives the screw 13 to rotate, the screw 13 drives the moving block 15 to move, the moving block 15 drives the cylinder 11 to move, and the cylinder 11 drives the sliding part 8 to slide. While the sliding part 8 slides, the sliding part 8 drives the cleaning roller 5 to move. Under the action of the guide bar 18 and the guide groove 19, the cleaning roller 5 moves relative to the fixed part 7, and at this time, the length of the combination of the cleaning fixed roller 6 and the cleaning roller 5 is longer than the length of the photovoltaic panel.

[0045] When the cleaning and adjusting frame 3 needs to be adapted to the inclination angle of the photovoltaic panel, the cylinder 11 is started, and the telescopic end of the cylinder 11 drives the sliding part 8 to swing, and the sliding part 8 drives the fixing part 7 to swing. At this time, the fixing part 7 swings with the hinge point between the vertical rod 10 and the fixing part 7 as the center of the circle, and finally the inclination angle of the cleaning and adjusting frame 3 is equal to the inclination angle of the photovoltaic panel.

[0046] Then, the second motor 20 is started, and the driving shaft of the second motor 20 drives the third gear 24 to rotate. The third gear 24 drives the second gear 23 and the first gear 22 to rotate through the first transmission chain 21. The first gear 22 and the second gear 23 respectively drive the cleaning roller 5 and the cleaning fixed roller 6 to rotate in the same direction. Then, the driving wheel 2 drives the mobile lifting frame 1 to move along the laying direction of the photovoltaic panels. At this time, the cleaning roller 5 and the cleaning fixed roller 6 that rotate simultaneously clean the surface of the photovoltaic panels together.

[0047] In summary, the cleaning and adjusting frame 3 is driven by the swing mechanism to stretch and swing, so that the cleaning and adjusting frame 3 can adapt to photovoltaic panels of different lengths and inclinations, thereby facilitating the cleaning of photovoltaic panels of different lengths and inclinations.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
