[0034] An annular mounting groove 31 is provided at the upper end of the side of the spherical mounting seat 3, and a protective member 9 is provided inside the annular mounting groove 31.

[0042] The drone has two sets of parallel rotor support frames 1, so that the two rotors 41 can be kept parallel when the rotors 41 rotate ninety degrees, which is convenient for the drone to travel on the road.

[0043] The entire UAV detection robot uses a spiral wing, which can protect the spiral wing 41, and the spiral wing 41 can be adjusted and positioned, so that the four-rotor UAV detection robot can be used on water, land and air, avoiding the UAV colliding with the ground or falling into the water during low-altitude flight, thereby avoiding damage to the detection equipment.
