The invention has the beneficial effects that: when using, this device monitors the direction of advance through the camera, and the in-process is advanced through the radar scanning and the distance between the pipeline inner wall simultaneously to this controlling means walks in the bend according to distance change controlling means when the bend, and then passes through the bend smoothly, when meetting the obstacle that condenses, can clean the barrier through high pressure steam or high pressure water smoke, and then dredge the pipeline inside, and is convenient effective, great increase the convenience to the pipeline mediation.
In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
