[0023] An amphibious geological survey unmanned aerial vehicle of the present utility model includes an unmanned aerial vehicle body 1, a traveling device 2, a rotating platform 3, a rotating base 4, and a camera 5. The unmanned aerial vehicle body 1 includes a frame 11 and a plurality of rotors 12. The lift generated by the rotation of the plurality of rotors 12 drives the unmanned aerial vehicle to fly. When ground survey is required, the plurality of rotors 12 are stopped from operating, and the traveling device 2 drives the unmanned aerial vehicle to move on the ground. Further, in order to obtain a larger field of view, when the unmanned aerial vehicle is flying, the camera 5 is generally arranged below the unmanned aerial vehicle; when walking on the ground, the camera 5 is generally arranged above the unmanned aerial vehicle. The rotating platform 3 is horizontally sleeved outside the frame 11. The rotating platform 3 is rotatably connected to the frame 11. Through the longitudinal rotation of the rotating platform 3, through the longitudinal rotation of the rotating platform 3 relative to the frame 11, the rotating base 4 is driven to move on the upper and lower sides of the unmanned aerial vehicle, and the rotating base 4 drives the camera 5 to rotate axially. The amphibious geological survey unmanned aerial vehicle of the present application can meet the survey operations of more different terrains, ensure the breadth of the shooting field of view, and improve the survey efficiency.

[0024] The rotating base 4 includes a rotating base 41, a shock-absorbing pan-tilt 42, and a fixing bracket 43. The rotating base 41 is arranged on the rotating platform 3. The shock-absorbing pan-tilt 42 is connected to the output end of the rotating platform 3. The fixing bracket 43 connects the shock-absorbing pan-tilt 42 and the camera 5. The rotating base 41 drives the shock-absorbing pan-tilt 42 to rotate in the plane direction.

In addition, the shock-absorbing sheet 462 is a hollow structure, and a plurality of hollow holes 464 are provided on its upper and lower sides for the gas to pass through, so as to avoid forming a resistance to the UAV when the wind force is too large and affecting the flight stability of the UAV.
