Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cleaning devices, in particular to a scrubbing device of a photovoltaic cleaning robot. Background Art

[0002] Photovoltaic panel cleaning robots are used to clean photovoltaic panels. The application of photovoltaic panel cleaning robots can significantly improve the operating efficiency and power generation benefits of photovoltaic power stations and reduce operation and maintenance costs. Existing photovoltaic cleaning robots usually use a brushing device to brush the panel, and the motor drives the brush to rotate and brush. However, since the photovoltaic panels may be uneven or encounter obstacles, the brush may resist the obstacles and cause the robot to be unable to move. In addition, if the brush cannot maintain the contact surface with the photovoltaic panel, the cleaning effect will be reduced. For example, the patent with publication number CN111420959A discloses a cleaning brush for a photovoltaic panel cleaning robot. By installing multiple movable rods with squeeze rollers at equal intervals at the bottom end of the extrusion frame, and the movable rods are connected to the extrusion frame by springs, the brush pad can be tightly fitted to the surface of the photovoltaic panel at all positions. However, in the above technical solution, the rotation of the brush pad is not circular, and it is difficult to rotate; in addition, it is difficult to cross when encountering uneven conditions.

[0022] like Figures 1 to 4As shown, a brushing device of a photovoltaic cleaning robot in this embodiment includes a housing 1 and a brush assembly 5 arranged on the housing 1. The brush assembly 5 is connected to the housing 1 through a swing assembly 8, so that the brush assembly 5 can swing up and down relative to the housing 1 when encountering a raised part. The swing assembly 8 includes a fixed block 81, a connecting plate 82 and a knob 83. The fixed block 81 is connected to the housing 1 through a locking member 84. The fixed block 81 is provided with a matching hole 811. The connecting plate 82 is connected to the brush assembly 5. The connecting plate 82 is provided with a connecting hole 821 corresponding to the matching hole 811. A pin 85 is passed through the matching hole 811 and the connecting hole 821, so that the connecting plate 82 can rotate around the pin. The connecting plate 82 is also provided with an arc hole 822. The locking member 84 is passed through the arc hole 822, so that the locking member 84 can move relative to the arc hole 822. The knob 83 includes a rod body 831, which is threadedly connected to the connecting plate 82. One end of the rod body 831 is arranged opposite to the fixed block 81, and the other end is provided with an operating part 832, and the operating part 832 is located above the connecting plate 82. In the above technical solution, when the photovoltaic cleaning robot moves, the brush assembly 5 brushes the photovoltaic panel. When the brush assembly 5 encounters an obstacle, the brush assembly 5 is subjected to pressure, and the connecting plate 82 rotates around the pin shaft 85 and is guided by the arc hole 822. By rotating the operating part 832, the user can raise and lower the rod body 831, thereby adjusting the floating distance of the connecting plate 82. Through the above technical solution, the photovoltaic cleaning robot can adaptively adjust the position of the brush assembly according to the undulating state on the panel during the cleaning process, thereby improving the brushing effect and obstacle crossing ability.

[0023] In this embodiment, the connecting plate 82 is L-shaped, and a connecting hole 821 is provided on the side of the connecting plate 82. The top of the connecting plate 82 is connected to the rod body 831, so that the operating part 832 is located at the top, which is convenient for users to operate. The connecting plate 82 is provided with a nut 822, and the rod body 831 is threadedly connected to the nut 822, so that the rod body can be raised and lowered by rotating the rod body 831.

[0024] In this embodiment, the brush assembly 5 includes a housing 51, and a brush motor 52 is provided on the housing 51. The brush motor 52 is arranged outside the housing 51, so as to avoid being restricted by the housing 51 and adopt a brush motor 52 with stronger power. A brush 53 is provided below the housing 51, and the brush 53 is connected to the brush motor 52 through a side transmission mechanism 54. Through the above technical solution, the brush motor 52 drives the brush 53 to rotate through the side transmission mechanism 54. The brush motor 52 is provided with a protective cover 55, so as to enhance the protection of the brush motor 52. The driving rod 521 of the brush motor 52 is parallel to the brush 53 and is located above the housing 51. The driving rod 521 is connected to the side transmission mechanism 54, and the side transmission mechanism 54 is driven by the driving rod 521. The side transmission mechanism 54 can adopt an existing belt transmission mechanism, which is a conventional technical means in the field and will not be described in detail. The housing 51 is provided with a bracket 56, and the driving rod 521 is inserted into the bracket 56. Since the driving rod 521 is relatively long, the rotation stability of the driving rod 521 can be improved through the bracket 56. The two sets of swing assemblies 8 are symmetrically arranged on the brush assembly 5, and the brush motor 52 is arranged between the two sets of swing assemblies, so that the brush assembly 5 can swing more smoothly, and the center of gravity of the brush assembly 5 is closer to the middle.

[0025] The brushing device of a photovoltaic cleaning robot of the present embodiment can adaptively adjust the position of the brush assembly according to the undulating state of the panel during the cleaning process, so that the brush maintains contact with the panel, thereby improving the brushing effect and obstacle crossing capability.
