After pushing the mounting tube 1 to move a distance, the cleaning tube 33 is driven to move by the second electric telescopic rod 32 during the movement. At the same time, water is pumped into the transmission tube 2 through the water supply pump 42 and the pipeline. Then, the transmission tube 2 pumps the cleaning water into the cleaning tube 33 through the first connecting tube 21 and the first hose 34, and then the water is sprayed out through the cleaning nozzle 35 on the cleaning tube 33 to flush the inner wall of the pipeline.

[0054] After cleaning a certain distance, the driving mechanism stops rotating at this time. According to the inner diameter of the pipeline, the detection box 24 is driven to move by the first electric telescopic rod 23, and the detection box 24 drives the detection column 25 to move, so that the ball 26 on the detection column 25 is against the inner wall of the pipeline, and the detection rod box moves in the detection box 24, and the second spring 28 is stretched. Then, the transmission tube 2 is driven to rotate at a low speed by the driving mechanism, and the second electromagnetic iron plate 292 on one side of the mounting ring 291 on the transmission tube 2 is started.

[0055] The working principle of the present invention is as follows: the installation tube 1 is placed into the pipeline to be inspected, and then the size is changed by a variable diameter driving mechanism to adapt to the size of the pipeline to be inspected. Then the variable diameter driving mechanism drives the installation tube 1 to move in the pipeline to be inspected, and at the same time, the dirt on the inner surface of the pipeline is flushed and cleaned by a cleaning detection mechanism during the movement. After cleaning a certain distance, the variable diameter driving mechanism stops working and stops driving the installation tube 1 to move. Then, the detection mechanism is driven to detect the cleaned inner wall of the pipeline, which greatly improves the detection accuracy, thereby realizing accurate detection of the inner walls of pipelines with different diameters.
