Place the device in the drain pipe 2. After placing it, the directional wheel 6 contacts the inner wall of the drain pipe 2 to orient and support the whole device. Turn on the first motor 305 to drive the worm 306 to rotate, and then drive the worm gear 307 to rotate. The rotation of the worm gear 307 drives the walking wheel 304 to rotate, so that the walking wheel 304 moves along the inner wall of the drain pipe 2, and the walking base 3 moves along the inner wall of the drain pipe 2. When moving to the position to be repaired, turn on the second motor 7 to drive the second rotating shaft 8 to rotate, and then drive the rotating column 9 to rotate. The rotation of the rotating column 9 drives the adjusting column 11 to rotate, and then drives the mounting column 12 to rotate. The scraper 13 on the mounting column 12 trims the inner wall of the drain pipe 2.
