[0016] like Figure 2 and Figure 3 As shown, a fixed beam 42 is fixed on the inner side of the cleaning ring 4, and fixed handles 43 are fixed on both sides of the fixed beam 42. The adjacent ends of the two connecting ropes 41 are tied to the two fixed handles 43 respectively. When the two motors 5 are started, one rotating rod 52 reels one connecting rope 41, and the other rotating rod 52 unwinds the other connecting rope 41, the cleaning ring 4 can be driven by the fixed beam 42 to move in the No. 1 pipeline 1 to clean the inner wall of the No. 1 pipeline 1; and the No. 1 pipeline 1 is connected to the elbow 2 through a flange, and the other end of the elbow 2 is also connected to the No. 2 pipeline 3 through a flange. When the connecting rope 41 or the cleaning ring 4 is damaged, the cleaning ring 4 can be moved into a elbow 2, and the two rotating rods 52 can unwind the two connecting ropes 41 at the same time. Then, after the flanges connecting the elbow 2 with the No. 1 pipeline 1 and the No. 2 pipeline 3 are removed, the connecting rope 41 or the cleaning ring 4 can be inspected, maintained or replaced.
