Pipeline detection device and detection method

The invention relates to the technical field of pipeline detection, in particular to a pipeline detection device and method. The pipeline detection device comprises a main body mechanism, a bundling mechanism, a detection mechanism, a control mechanism and a positioning mechanism, the main body mechanism comprises a first supporting rod and a supporting surface, the supporting surface is of an umbrella-shaped structure, and the end of the first supporting rod is connected with the center of the supporting surface; the collecting mechanism is arranged between the first supporting rod and the supporting surface and is used for adjusting the opening angle of the supporting surface; the detection mechanism is arranged on the supporting surface; and the positioning mechanism is arranged on the supporting surface. By adopting the pipeline detection device, weak points, leakage points and the specific position of the growth ring in the pipeline can be determined, and constructors can conveniently find the weak point
