[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a remote sensing and mapping drone, comprising a body, arms fixedly connected to both sides of the body, a plurality of blades rotatably arranged on the outer surface of the arms, a camera arranged at the bottom end of the body, an auxiliary device arranged at the bottom end of the body, the auxiliary device comprising a U-shaped rod, T-shaped blocks fixedly connected to both ends of the U-shaped rod, an inclined plate fixedly connected to one side of the U-shaped rod, a groove and two T-slots formed at the bottom end of the body, the outer surface of the T-block slides on the inner wall of the T-slot, a motor is arranged inside the groove, a screw is arranged at the output end of the motor, one end of the screw is rotatably connected to one side of the inner wall of the T-slot, and the outer surface of the screw is threadedly connected to the inner wall of a T-block.

[0006] The effect achieved by the above components is: by setting the inclined plate, when the drone remote control device finds that there is an obstruction on the camera surface during flight, the motor inside the groove can be operated to drive the screw to rotate, so that the T-shaped block at one end of the U-shaped rod slides on the outer surface of the screw and the inner wall of the T-shaped groove, and the two T-shaped blocks slide on the inner wall of the T-shaped groove to drive the U-shaped rod to move toward the camera, and the obstruction on the camera surface is pushed away by the inclined plate on the outer surface of the U-shaped rod, so that the camera can collect information normally.

[0007] Preferably, two positioning blocks are fixedly connected to the outer surface of the U-shaped rod, and one side of the positioning block slides on the bottom end of the body.

[0008] The effect achieved by the above components is that when the U-shaped rod moves, one side of the two positioning blocks will slide at the bottom end of the machine body. The positioning blocks can limit the angle between the U-shaped rod and the machine body, thereby avoiding the angle of the U-shaped rod from being deflected and affecting the normal movement of the U-shaped rod as much as possible.

[0009] Preferably, a plurality of through holes are formed on the outer surface of the inclined plate, and the through holes are linearly distributed on the outer surface of the inclined plate.

[0013] Preferably, a rectangular piece is fixedly connected to the top end of the fan blade, and the rectangular piece is a cotton piece.

[0014] The effect achieved by the above components is: when the fan blades rotate under the camera, the cotton rectangular piece at the top will contact the surface of the camera lens, wipe off the dirt on the surface of the camera lens, and further ensure the normal use of the camera.

[0015] Preferably, a protective device is provided on the outer surface of the machine arm, and the protective device includes a groove ring, a plug rod is fixedly connected to the bottom end of the groove ring, and a slot is provided on the side of the outer surface of the machine arm close to the blade.

The groove ring is used to protect the outside of the blade, thereby avoiding as much as possible the blade from being collided during the flight of the drone and affecting the normal flight of the drone.

[0017] Preferably, a plurality of rectangular strips are fixedly connected to the outer surface of the insertion rod, and the rectangular strips are rubber strips made of rubber material.

[0018] The effect achieved by the above components is that the rectangular strip made of rubber material can increase the friction between the insertion rod and the inner wall of the slot when the insertion rod is inserted into the slot, so that the insertion rod is not easy to fall off from the inside of the slot.

[0019] Preferably, a slot block is fixedly connected to the top end of the insertion rod, and a groove is formed on one side of the slot block.

[0020] The effect achieved by the above components is that the groove ring can be more conveniently grasped by hand at the groove on the outer surface of the groove block to pull the insertion rod out from the inside of the slot and remove the groove ring.

When the U-shaped rod 26 moves, one side of the two positioning blocks 212 will slide at the bottom end of the body 1. The positioning blocks 212 can limit the angle between the U-shaped rod 26 and the body 1, and avoid the angle of the U-shaped rod 26 from being deflected and affecting the normal movement of the U-shaped rod 26 as much as possible. A plurality of through holes 28 are opened on the outer surface of the inclined plate 27, and the through holes 28 are linearly distributed on the outer surface of the inclined plate 27.

When the drone is used, the plug rod 32 at the bottom end of the groove ring 33 can be inserted into the slot 31 on the outer surface of the arm 4, so that the groove ring 33 is located on the outside of the blade 5. The groove ring 33 is used to protect the outside of the blade 5, so as to avoid the blade 5 from being hit during the flight of the drone and affecting the normal flight of the drone as much as possible.
