[0002] When the water pipe detection instrument enters the pipeline, the optical cable needs to be lowered into the pipeline with the detection instrument for real-time communication. The traditional working method is to use manual pushing, and the roller and the pipeline (the starting point where the optical cable enters the pipeline) need to be kept in a straight line.
