[0001] The utility model relates to the technical field of laser radar, in particular to a laser radar dust removal device. Background Art

[0002] LiDAR is usually placed in an open-air environment for operation. Dust easily accumulates on the laser of LiDAR. If it is not cleaned regularly, it may affect the operation of the radar at best, or even damage the radar's tight components;

[0003] A Chinese patent publication (publication number: CN216387357U) discloses a laser radar device capable of automatic dust removal, which includes shielding plates movably installed at the middle and lower ends of both sides of the collection frame, extension plates fixed at the edges of the shielding plates, connecting springs fixed at the ends of the extension plates close to each other, and moving blocks fixed at the other ends of the connecting springs, fixing rings fixed at the lower ends of both sides of the laser radar device, a rotating rod passing through the end of the fixing ring close to the laser radar device, a sleeve rod sleeved on the rotating rod, a slider fixed on the top of the sleeve rod, and a retaining ring fixed at the lower end of the sleeve rod, and a sleeve rod sleeved at the upper end of the sleeve rod. A ring is provided with an elastic rod movably arranged on one side of the ring away from the laser radar device, and an elastic ball is fixed on the other end of the elastic rod. The utility model solves the technical problems that the existing laser radar device with automatic dust removal is not thorough enough when cleaning the dust on the laser radar shell, and the cleaned dust is not convenient enough when being processed in a unified manner.
