[0051] Step 1: Place the pipeline horizontally in the pipeline groove 5, and then push the pipeline toward the arc-shaped limit plate 9. The crossbeam 7 passes through the interior of the pipeline. One end of the pipeline is blocked by the arc-shaped limit plate 9. The cylinders 11 on both sides of the top surface of the pipeline support seat 3 drive the clamping blocks 12 on both sides of the pipeline to press on the outer wall of the pipeline to fix the pipeline. The clamping blocks 12 are higher than the height of the axis of the pipeline.

[0052] Step 2: The first motor 404 drives the first lead screw 405 to rotate, and the first lead screw 405 drives the first movable block 403 to slide on the first T-shaped slide rail 402, so that the first movable block 403 moves toward the direction of the first motor 404, and then the first support rod 406 supports the pipe support seat 3 through the first connecting block 407, so that the adjustment mechanism 4 pushes the pipe support seat 3 upward, and the pipe support seat 3 rotates on the vertical plate 2 through the third connecting block 201, so that the pipe support seat 3 tilts, and then the pipe tilts;

[0054] The diameter of the pipeline is known data. Before cleaning, the pipeline diameter data is input into the controller through the input module. The controller controls the fourth motor 811 to operate according to the pipeline diameter data, thereby driving the third gear 812 to rotate. At the same time, with the cooperation of the teeth in the second annular groove 8045, the collar 8041 rotates. The third arc hole 8042 and the adjusting rod 8044 cooperate to drive the lifting rod 8043 to be propped up on the fixed rod 8046, so that the vertical distance between the outermost edge of the second disc cutter 8047 and the axis of the pipeline is equal to the radius of the pipeline. The positional relationship between the second disc cutter 8047 and the inner wall of the pipeline is as follows: Figure 6 ;

[0056] Step 4: before cleaning, the controller controls the fifth motor 8035 to operate according to the pipe diameter data, and drives the two second movable blocks 8036 to move away from each other on the second T-shaped slide rail 8032 through the second lead screw 8034, so that the two second support rods 8037 support the lifting plate 8039 upward, so that the vertical distance between the outermost edges of the first disc cutter 80316 and the scraper 80313 and the pipe axis is equal to the radius of the pipe, and the brush 80312 contacts the inner wall of the pipe;

[0057] The third motor 808 drives the second gear 809 to rotate, and at the same time, with the cooperation of the teeth in the first annular groove 80317, the sleeve 8031 ​​rotates on the outer wall of the cylinder 801, thereby driving the first disc cutter 80316, the scraper 80313, and the brush 80312 on the lifting plate 8039 to rotate;

[0058] The sleeve 8031 ​​rotates on the outer wall of the cylinder 801, and the first disc cutter 80316 rotates accordingly. The first disc cutter 80316 cuts the strip-shaped solid dirt along the inner wall of the pipe in a spiral manner, and cuts the dirt into a plurality of blocks.

[0059] Step 5: The scraper 80313 rotates with the sleeve 8031, and the scraper 80313 scrapes off the blocky dirt on the inner wall of the pipe. The position relationship between the scraper 80313 and the inner wall of the pipe is as follows: Figure 7 ;

[0060] Step 6: The nozzle 8021 is connected to a water supply pipe, and the water supply pipe supplies water to the nozzle 8021, thereby realizing water spraying of the nozzle 8021;

[0061] The nozzle 8021 flushes the scraped inner wall, and at the same time the brush 80312 rotates with the sleeve 8031, and the brush 80312 scrubs the scraped inner wall. Since the pipeline is inclined on the pipeline support seat 3, the flushed waste water flows along the bottom of the pipeline toward the lower direction of the pipeline and flows out from the lowest port of the pipeline.
