Mobile pressure pipeline leakage point positioning detector

The utility model discloses a mobile pressure pipeline leakage point positioning detector, and belongs to the field of pipeline detection. A movable type pressure pipeline leakage point positioning detector comprises a connecting ring, a driving assembly installed on the connecting ring and used for driving the rotating ring to rotate, a sliding seat connected to the connecting ring in a sliding mode, connected with the rotating ring and connected with a detector body, and a plurality of moving assemblies arranged on the connecting ring and used for moving the moving assemblies. The connecting ring is driven to move on the pipeline. After the two arc-shaped frames are connected on the pipeline to form the connecting ring, the driving assembly can drive the detector main body on the sliding seat to rotate around the pipeline, and the connecting ring moves on the outer wall of the pipeline through the guide wheel, so that the detector spirally advances on the outer side of the pipeline and carries out detection
