Pipeline intelligent inspection system

A pipeline intelligent inspection system comprises a pipeline inspection robot, a detection unit, an image display unit, a communication unit, a remote control unit and the like. The pipeline intelligent inspection system controls a rolling wheel to abut against the inner wall of a pipeline according to pipeline inner diameter information transmitted by the detection unit, then a walking r6obot isdriven to operate, the pipeline inspection robot is driven to walk in the pipeline, and meanwhile, a cleaning head is driven to rotate and scrape dirt off the surface of the inner wall of the pipeline. The rolling wheel at the end of a support arm can be controlled correspondingly according to the size of the pipeline, thereby keeping closely abutting against the inner wall of the pipeline, the position of the pipeline inspection robot in the pipeline can be maintained through the abutting effect of the rolling wheel, and driving and control of up-down operation of the pipeline inspection robot are achieved.
