13. The pipe inner wall cleaning device according to claim 1, wherein two washing shafts are arranged, and the washing shafts drive the recovery shell to rotate through the rotating motor so as to clean the pipe inner wall in a follow-up rotation mode.

14. The pipe inner wall cleaning device according to claim 1, wherein the surface of the rotary isolation plate is provided with an arc-shaped concave surface, the isolation plate is circularly arranged, the outer diameter of the isolation plate is smaller than that of the inner wall of the conductive pipe, and the isolation plate is not in contact with the inner wall of the conductive pipe.

15. A cleaning method based on the pipe inner wall cleaning device according to claim 1, comprising the following steps:

when the cleaning piece is in contact with the cleaning part, the exchange part starts to rotate the rotating block, so that the connection between the air pressure device and the conveying part is realized, at the moment, the air pressure generated by the air pressure device is started to move towards the pipe in the conveying part, and the pressure of the air pressure pushes the cleaning piece to move so as to drive the cleaning part to move, and the inner wall of the pipe is cleaned;

16. The cleaning method according to claim 15, wherein the pulley of the cleaning part moves on the inner wall of the pipe while cleaning the inner wall of the pipe during the movement, and the fan blade motor inside the cleaning part recovers impurities generated during the cleaning to prevent the accumulation in the pipe from affecting the movement of the cleaning part.

17. The cleaning method according to claim 16, wherein the cleaning member is disposed in contact with the pipe during the pushing movement of the air pressure, so that the cleaning member is cleaned for the second time to ensure the cleaning effect of the inner wall of the pipe.
