The mounting disk 51 is circumferentially mounted with at least two groups of long handles 52, and a soft brush 53 is installed at one end of the long handle 52 close to the sensor 7. The cleaning end of the soft brush 53 is flush with the end of the sensor 7 to be cleaned, and the length of the soft brush 53 is greater than the maximum distance from the axis of the mounting disk 51 to the edge of the end of the sensor 7 to be cleaned. When cleaning, the cleaning end of the cleaning brush 6 is located between the cleaning end of the soft brush 53 and the end of the long handle 52 close to the sensor 7.

[0024] The controller 3 is electrically connected to the driving mechanism 2 .

[0025] Preferably, the driving mechanism 2 uses a motor 21 , and the controller 3 is electrically connected to the motor 21 .

[0026] Preferably, a first linear drive 11 is installed on the support frame 1 , and an output end of the first linear drive 11 is fixedly connected to the cleaning brush 6 .

[0027] The controller 3 controls the driving mechanism 2 to start, and the driving mechanism 2 drives the mounting plate 51 to rotate through the rotating shaft 4, and the mounting plate 51 drives the multiple groups of long handles 52 to rotate, and the long handles 52 drive the soft brushes 53 thereon to clean the end of the sensor 7 to be cleaned, and the soft brush 53 after cleaning continues to rotate under the cleaning brush 6, and the cleaning brush 6 cleans the soft brush 53 so that the soft brush 53 remains clean. It cleans itself while cleaning, reducing the cost of manual maintenance. The first linear drive 11 is used to adjust the distance between the cleaning brush 6 and the support frame 1, which is convenient for replacing the brush head and matching sensors 7 of different heights.

[0028] Preferably, the rotating shaft 4 includes a first rotating shaft 41 and a second rotating shaft 42. One end of the first rotating shaft 41 is fixedly connected to the output shaft of the motor 21. The other end of the first rotating shaft 41 begins to have a receiving groove 45. The receiving groove 45 opens toward the mounting plate 51. A group of adjustment grooves 43 are respectively opened on both sides of the receiving groove 45. The adjustment grooves 43 penetrate the side wall of the first rotating shaft 41. The receiving grooves 45 and the adjustment grooves 43 are connected. The length directions of the receiving grooves 45 and the adjustment grooves 43 are consistent with the length direction of the first rotating shaft 41. One end of the second rotating shaft 42 is fixedly connected to the mounting plate 51. The other end of the second rotating shaft 42 is inserted into the receiving groove 45. A cross bar 44 is installed at one end of the second rotating shaft 42 away from the mounting plate 51. Both ends of the cross bar 44 are inserted into the two groups of adjustment grooves 43. A second linear drive 12 is installed on the support frame 1. A connecting plate 13 is installed at the output end of the second linear drive 12.

[0033] In order to match sensors 7 of different heights, the second linear drive 12 starts to adjust the distance between the connecting plate 13 and the mounting frame 1. The connecting plate 13 drives the second rotating shaft 42 to slide in the accommodating groove 45 to approach or move away from the mounting frame 1, thereby adjusting the distance from the mounting plate 51 to the mounting frame 1. The cross bar 44 follows the second rotating shaft 42 to slide in the adjusting groove 43. During cleaning, since the cross bar 44 is horizontally inserted into the adjusting groove 43 and the rotation plane of the first rotating shaft 41 is perpendicular to the length direction, the cross bar 44 is perpendicular to the adjusting groove 43. When the first rotating shaft 41 rotates, the cross bar 44 drives the second rotating shaft 42 to rotate, thereby driving the sweeper 5 to clean.

In this case, the rotating shaft 4 is also replaced with a non-adjustable fixed transmission shaft, and the bracket at the second linear drive 12 can be cancelled.
