Description

Technical Field

[0001] The present invention relates to the technical field of pipeline maintenance, and in particular to durable maintenance equipment for water supply and drainage pipelines. Background Art

[0002] Pipeline maintenance includes external anti-corrosion layer repair and internal repair, which aims to restore the normal use function of damaged and leaking transmission pipelines through various technologies. In terms of pipeline maintenance, external anti-corrosion layer repair and internal repair are the two main technical means. External anti-corrosion layer repair mainly targets the corrosion problem on the outside of the pipeline, and targeted repair is carried out after inspection and evaluation. Internal repair involves more complex technologies, such as hose flip lining technology. This method is to fully immerse the fiber hose with an anti-seepage membrane in resin, and use air pressure or water pressure to stick to the inner wall of the old pipeline, and thermosetting it to form a smooth lined fiberglass pipe, thereby completing the repair of the old pipeline.

[0003] In the prior art, when the drainage pipe is in use, the water transported inside it will rust the inner wall of the pipe, and then the inner wall of the pipe may lose the static balance state at the time of original installation due to rust and corrosion, and thus personnel often need to conduct regular maintenance on it. During the existing pipeline maintenance process, for pipes with smaller diameters, since maintenance personnel cannot enter the inside of the pipe, they usually need to use specific equipment to inspect the inside of it. At this time, due to the accumulation of dirt on the inner wall of the pipe during use, the inner wall of the pipe usually needs to be cleaned before the maintenance equipment enters the inside of the pipe. However, since the staff cannot enter the inside of the pipe, it is difficult for the staff to know the cleanliness of the inner wall of the pipe at this time, and dirt may remain on the inner wall of the pipe. Then, when the maintenance equipment enters the inner wall of the pipe, the remaining dirt may enter the gap between the moving wheels of the detection equipment, causing it to get stuck. At this time, the movement of the maintenance equipment is hindered, which may affect its subsequent use effect. Summary of the Invention
