The invention belongs to the technical field of intelligent detection, and discloses an all-terrain spiral detector which comprises a body with a built-in battery and two propulsion assemblies. The two propulsion assemblies are arranged on two sides of the body and are used for driving the body to freely move; the propulsion assemblies comprise support frames and pipe barrels, the support frames are fixedly connected with the body, and the pipe barrels are rotationally connected with the support frames; the two propulsion assemblies are symmetrically arranged, the pipe barrels are further provided with threaded blades, the threaded blades are wound on the outer surfaces of the pipe barrels and are spirally arranged, and spiral directions of the threaded blades are clockwise directions or anticlockwise directions. The all-terrain spiral detector has the advantage that the problems of poor obstacle crossing ability, single detection environments and relatively complicated structures of intelligent detection equipment in the prior art can be solved by the aid of the all-terrain spiral detector.
