[0031] It should be noted that the driving assembly is arranged to facilitate the up-down movement of the cleaning ring 401 around the camera 104, thereby improving the cleaning effect of the camera 104.

[0032] Working principle: after the surveying unmanned aerial vehicle completes the surveying task and lands on the landing platform 106, the fixed assembly is used to center and fix the surveying unmanned aerial vehicle, and after the surveying unmanned aerial vehicle is fixed, the push rod motor 204 is started to move the protective cylinder 202 close to the surveying unmanned aerial vehicle. During the movement of the protective cylinder 202, when the rubber sealing plate 303 at one end of the protective cylinder 202 abuts against the mounting plate 103 at the bottom of the machine body 102, the push rod motor 204 stops.
