[0018] The following is in conjunction with the appendix Figures 1-5 The present invention will be further described below.

[0019] To address the problems existing in the background technology, this application proposes the following technical solution: a drone mapping obstacle avoidance auxiliary device suitable for complex terrain.

[0020] The specific technical solution includes a mounting frame 1, inside which a surveying camera 2 is installed. A dust removal assembly 3 is installed on the outer wall of the surveying camera 2. The dust removal assembly 3 includes a transmission frame 301, a moving frame 303, and a rotating rod 306. The transmission frame 301 is located on top of the surveying camera 2, and a motor 302 is installed at one end of the transmission frame 301. A lead screw 304 is installed on the output shaft of the motor 302. The moving frame 303 is slidably connected inside the transmission frame 301, and the moving frame 303 is connected by a screw... The screw 304 is fitted with a threaded sleeve. A rack 305 is provided on the outer wall of the transmission frame 301. The top of the rotating rod 306 is rotatably connected to the outer wall of the bottom of the moving frame 303. A gear ring 308 is provided on the outer wall of the top of the rotating rod 306. The gear ring 308 and the rack 305 mesh with each other. A dust removal brush 307 is provided on the outer wall of the rotating rod 306. It can automatically clean the sand and dust on the surveying camera 2, so as to avoid the surveying camera 2 being blocked by sand and dust when used in complex terrain with large sand and dust, which would affect the terrain surveying.

[0021] In specific implementations, such as Figure 2 and Figure 5 As shown, the top of the surveying camera 2 is provided with a mounting component 4, which includes a mounting box 401, a mounting base 402 and a movable plate 403. The mounting box 401 is snapped into the two mounting bases 402, which are located at the bottom of the drone. The mounting component 4 is used to fix the mounting box 401 in the two mounting bases 402, and also to mount the surveying camera 2 on the drone.

[0022] Furthermore, the movable plate 403 slides inside the mounting box 401, and a spring 405 connected to the movable plate 403 is provided on the inner wall of the mounting box 401. When the movable plate 403 is not held by the top block 407, the elastic force of the spring 405 can push the movable plate 403 to move.

[0023] Furthermore, the outer wall of the movable plate 403 is provided with a plug 404, which is inserted into the mounting base 402 to fix the mounting box 401.

[0024] Furthermore, the mounting box 401 is rotatably connected to a rotating cylinder 406, and the rotating cylinder 406 is provided with a rotating knob 410 on the outer wall of the mounting box 401, which can drive the rotating cylinder 406 to rotate.

[0025] Furthermore, a top holding block 407 is provided on the outer wall of the rotating drum 406 to contact the moving plate 403, and an inner rod 408 is provided on the inner wall of the top of the mounting box 401. When the rotating drum 406 rotates, it will drive the top holding block 407 to rotate.

[0026] Furthermore, a torsion spring 409 is provided on the outer wall of the inner rod 408 and is connected to the rotating cylinder 406. The torsion spring 409 is sleeved on the outside of the inner rod 408, and the torsional force of the torsion spring 409 can drive the rotating cylinder 406 to rotate.

[0027] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview: In use, the mounting base 402 is pre-fixed to the bottom of the drone. The mounting box 401 is inserted between the two mounting bases 402. The knob 410 is released, and the torsional force of the torsion spring 409 will drive the rotating cylinder 406 and the top holding block 407 to rotate. This allows the top holding block 407 to push the moving plate 403 to move, so that the insertion block 404 can be inserted into the mounting base 402. This allows the surveying camera 2 to be installed on the drone conveniently and quickly without the need for multiple screws, making installation or disassembly for maintenance more convenient and efficient. Turning on the motor 302 drives the lead screw 304 to rotate, which allows the moving frame 303 to synchronously drive the rotating rod 306 to move axially on the lead screw 304. As the rotating rod 306 moves, the gear ring 308 will mesh with the rack 305, which allows the rotating rod 306 to drive the dust removal brush 307 to rotate and clean the dust from the surveying camera 2. This avoids the problem of the surveying camera 2 being blocked by dust when used in complex terrain with a lot of dust, which would affect the terrain surveying.
