One side of the lifting plate 5 is detachably fixedly connected with a lens for wiping the surveying and mapping device body 3. When the lens of the surveying and mapping device body 3 needs to be cleaned, the driving motor 7 is started, and the driving motor 7 drives the rotation of the driving shaft 8 and the two active bevel gears 9. The two active bevel gears 9 drive the synchronous rotation of the two driven bevel gears 10. The two driven bevel gears 10 drive the synchronous rotation of the two lifting screws 12. The two lifting screws 12 drive the two lifting plates 5, the moving plate 19 and the wiping block 20 to move up or down. When the wiping block 20 repeatedly moves up and down, the lens of the surveying and mapping device body 3 can be wiped repeatedly several times, and then the dust on the lens of the surveying and mapping device body 3 can be wiped off, thereby ensuring the cleanliness of the lens of the surveying and mapping device body 3 and improving the accuracy of surveying and mapping.

When the drone body 1 is not in use and needs to be stored, the moving plate 19 is driven downward by the driving motor 7, and the downward movement of the moving plate 19 drives the shielding cloth 18 to move downward The shielding cloth 18 moves, and the winding disk 17 and the rotating shaft 16 automatically rotate and drive the torsion spring 15 to twist and store energy until the movable plate 19 moves down and abuts against the bottom inner wall of the protective frame 4. At this time, the protective frame 4, the movable plate 19 and the shielding cloth 18 are arranged to seal and protect the lens of the surveying and mapping device body 3, which not only achieves the purpose of dustproof protection, but also avoids the situation where the lens of the surveying and mapping device body 3 is damaged by collision with foreign objects.

[0032] In the utility model, when in use, the wiping block 20 and the movable plate 19 are located above the lens of the surveying and mapping device body 3, so as not to hinder the normal surveying and mapping work of the surveying and mapping device body 3. When it is necessary to clean the lens of the surveying and mapping device body 3, the driving motor 7 is started, and the driving motor 7 drives the rotation of the driving shaft 8 and the two active bevel gears 9. The two active bevel gears 9 drive the synchronous rotation of the two driven bevel gears 10. The two driven bevel gears 10 drive the synchronous rotation of the two lifting screws 12. The two lifting screws 12 drive the two lifting plates 5, the movable plate 19 and the wiping block 20 to move up or down. When the wiping block 20 repeatedly moves up and down, the lens of the surveying and mapping device body 3 can be wiped repeatedly several times, so as to wipe off the dust on the lens of the surveying and mapping device body 3, thereby ensuring the cleanliness of the lens of the surveying and mapping device body 3 and improving the accuracy of surveying and mapping. Dust can be discharged from the dust outlet 13. When the drone body 1 is not in use and needs to be stored, the moving plate 19 can be driven downward by the driving motor 7. The downward movement of the moving plate 19 drives the shielding cloth 18 to move downward. Driven by the shielding cloth 18, the winding disk 17 and the rotating shaft 16 automatically rotate and drive the torsion spring 15 to twist and store energy until the moving plate 19 moves down and abuts against the bottom inner wall of the protective frame 4. At this time, the lens of the surveying and mapping device body 3 can be sealed and protected by the setting of the protective frame 4, the moving plate 19 and the shielding cloth 18, which not only achieves the purpose of dustproof protection, but also avoids the situation where the lens of the surveying and mapping device body 3 is damaged by collision with foreign objects. When in use, the driving motor 7 is started in the reverse direction to make the moving plate 19 move up and reset. At this time, under the torsion of the torsion spring 15, the rotating shaft 16 and the winding disk 17 rotate in the opposite direction to reel the shielding cloth 18.
