The brush plate 105 is made of sponge material. The device is installed at a high place through the support frame 101, so that the pipeline is sleeved outside the internal spray pipe 102 from bottom to top. Then, it is clamped and fixed by the fixing device, and the first hydraulic rod 104 is extended to drive the brush plate 105 to tightly attach to the inner wall of the pipeline. Then, the fixing device drives the pipeline to rotate, and the cleaning agent is sprayed from the internal spray head 103 through the internal spray pipe 102 to cooperate with the brush plate 105 to clean the inner wall of the pipeline;

On both sides of the rear clamping plate 204, two pairs of supporting rollers 207 are symmetrically arranged. The clamping plates 204 are slidably connected to the guide rail 201. The guide rail 201 is made of 304 stainless steel. The clamping motor 202 drives the forward and reverse threaded screw rod 203 to rotate, pushing the two clamping plates 204 to move relatively along the guide rail 201, thereby driving the two pairs of driving rollers 205 and the two pairs of supporting rollers 207 to move relatively, clamping the pipeline and fixing it. Subsequently, the driving motor 206 drives the driving rollers 205 to frictionally drive the pipeline to rotate;

[0027] In this embodiment: The external cleaning device includes a support plate 301. A second hydraulic rod 302 is installed on the support plate 301.
