It can greatly reduce the need for human intervention, improve the autonomy of the drone, and effectively reduce the risk of accidents and damage.

[0003] At present, the obstacle avoidance of drones during flight is to use laser radar to detect obstacles in front, so that the drone can avoid obstacles. However, the laser radar on existing drones is generally installed in a fixed way, which narrows the range that the laser radar can scan, making the drone's ability to avoid obstacles poor, thus affecting the safety of the drone during flight.

Then, in cooperation with the reciprocating expansion and contraction of the two lidars, the two lidars are respectively in contact with the wiping cloth, thereby realizing the wiping of the dust on the outer wall of the lidar, and thus improving the detection accuracy of the lidar. When the wiping cloth is not used, only need to control the two wiping plates to move upward, so that the two wiping plates move above the lidar, thus avoiding the wiping plates from affecting the detection range of the lidar.

[0015] 3.

Since the second tooth plate is connected to the top of the first tooth plate through a lifting rod and a reset spring, the first tooth plate will no longer move downward during the process of the engagement between the spur gear and the first tooth plate and the second tooth plate, thereby ensuring the relative fixed height of the first moving rod and the two wiping plates. When the control rod is out of contact with the card rod, the first tooth plate is driven to move upward under the elastic force of the second spring, thereby driving the first moving rod and the two wiping plates to move upward, so that the two wiping plates are reset to their initial positions.

[0034] The operation process of this embodiment is: by controlling the motor 501 to drive the first rotating shaft 502 to rotate, the first rotating shaft 502 drives the first sprocket 503 and the turntable 504 to rotate, and then drives the connecting column 505 to rotate, so that the connecting column 505 further drives the rectangular frame 507 to move back and forth, and then drives the connecting rod 508 to move back and forth, so that the connecting rod 508 drives the cross plate 402 to move back and forth, providing power for the reciprocating back and forth movement of the cross plate 402.
