The self-lubricating liner 2 is coaxially attached to the inner wall of the sewage pipe body 1, and the self-lubricating liner 2 can rotate relative to the sewage pipe body 1. Specifically, a ring edge 3 is arranged on the inner wall of the sewage pipe body 1, and the left and right sides of the self-lubricating liner 2 are against the ring edge 3, so that the self-lubricating liner 2 can rotate without axial relative movement with the sewage pipe body 1. Five axial paddles 4 are distributed in a fan shape on the self-lubricating liner 2, and the axial paddles 4 are close to the bottom of the sewage pipe body 1. The center angle between adjacent axial paddles 4 is 30°;

The two driven rings 5 ​​are respectively close to the left and right ends of the sewage pipe body 1. The driven ring 5 and the active reciprocating ring 6 are coaxially arranged on the outside of the sewage pipe body 1. The two driven rings 5 ​​are connected by a plurality of connecting rods 7. The active reciprocating ring 6 is fixed on the connecting rod 7. A motor seat 8 is fixed on the active reciprocating ring 6. A servo motor 9 and a slide groove are arranged on the motor seat 8.

[0021] The above-mentioned axial paddle 4 is integrally arranged on the self-lubricating liner 2. The materials of the axial paddle 4 and the self-lubricating liner 2 are both polytetrafluoroethylene.
