The purpose of such a setting is that before the drone performs surveying and mapping, the device can rotate the adjusting dial to drive the adjusting screw to move in the adjusting conduit and lift the lifting disc, so that the mounting slider can move up, thereby adjusting the height of the surveying and mapping camera, and can adjust the height of the surveying and mapping camera according to the terrain of the drone's landing area, thereby avoiding the contact between the lens of the surveying and mapping camera and the ground obstacles, thereby avoiding affecting the use of the surveying and mapping camera;

[0047] In actual use, when the vacuum pump 50 is running, the gas will enter the air avoidance groove 41, and then flow into the inner cavity of the first-level filter hole 32 through the first-level filter hole 32, and then the gas will pass through the second-level filter hole 37 and the third-level filter hole 38 in turn, and then enter the flow channel tube 34, and then flow to the main airway 24, and flow into the annular groove 17 through the air hole 25, and then flow into the annular airway 12 along the first-level airway 15 and the second-level airway 14, and then enter the vacuum pump 50 through the first-level pipeline, and then enter the annular air cavity 52 through the second-level pipeline, and finally blow out through the blowing hole 53, thereby forming a protective effect on the lens 55.
