[0044] The control cabinet 6 is electrically connected to the cyclone generator 3 , the first regulating valve, the first solenoid valve 32 , the second regulating valve 42 , the second solenoid valve 44 and the third regulating valve 52 , respectively.

[0045] In this embodiment, when processing the pipeline, first move the box 1 to the pipeline, adjust the height of the box 1 by the lifting seat 2 so that the output pipe 31 is aligned with the pipeline and connected to the pipeline. Then put the abrasive into the material box 4, start the air compressor and the cyclone generator 3, and the high-pressure gas generates a rotating airflow after passing through the cyclone generator 3. The airflow drives the subsequent abrasive and water to rush into the pipeline to clean the pipeline. The rotating jet technology is used to form an unbalanced shear layer around the pipe wall, driving the abrasive to clean the hard dirt on the inner wall of the pipeline. The air intake is controlled by the first regulating valve, the abrasive amount is controlled by the second regulating valve 42, and the water amount is controlled by the third regulating valve 52, so that excellent cleaning effects can be achieved for pipelines of different diameters and lengths.

[0046] When spraying the inner wall of the pipeline, open the second solenoid valve 44 to discharge the abrasive in the material box 4 through the discharge pipe 43, and then inject the paint into the material box 4, close the third regulating valve 52, and start the equipment to drive the paint to coat the inner wall of the pipeline through the rotating airflow. A set of equipment is used to achieve the cleaning and spraying of the inner wall of the pipeline, which is convenient to operate and has high processing efficiency.

[0047] The control cabinet 6 and the box body 1 adopt a split structure to control the equipment in the box body 1, avoiding the influence of the water tank 5 in the box body 1 on the components in the control cabinet 6, and improving the service life of the equipment. In addition, for the complex outdoor working environment, the user can set the control cabinet 6 in a relatively flat place for operation, which improves the convenience of equipment operation.

[0048] In a preferred embodiment, if Figure 1 As shown, a box door 11 is provided on the front of the box body 1 to facilitate maintenance of the equipment in the box body 1; a feeding port 12 connected to the material box 4 is provided above the box door 11 to facilitate adding abrasives or coatings into the material box 4.

[0050] In this embodiment, after the box body 1 is moved to the pipeline to be processed, the adjusting hand wheel 210 is rotated to drive the worm 28 to rotate through the adjusting rod 27, and the worm 28 drives the lead screw 23 to rotate through the worm wheel 26. With the cooperation of the threaded structure, the support tube 24 is driven up and down, thereby driving the box body 1 to rise and fall, so that the output pipe 31 is aligned with the pipeline, ensuring that the abrasive or paint enters the pipeline smoothly, thereby improving the processing effect of the pipeline.

[0051] In a preferred embodiment, if Figure 1 and Figure 2 As shown, four first self-locking universal wheels 211 distributed in a rectangular shape are arranged on the bottom surface of the bottom plate 21 ; a first handle 13 is fixedly arranged on one side of the box body 1 , so as to facilitate moving the box body 1 through the first handle 13 .
