Description

Technical Field

[0002] Dredging and reclamation projects are the main means of developing, improving and maintaining waterways and port waters. During the construction process, the mixture of silt and water excavated by dredgers or other equipment must be transported to the reclamation area through pipelines. The pipelines for transportation are roughly divided into pipelines on land and pipelines above and below the water. Since there is a lot of silt to be transported, especially the clay particles contained in it, it will not only adhere to the pipe wall, but also carry silt, stones and other particles, affecting the transportation efficiency, and even blocking the transportation pipeline in serious cases, so the pipeline must be cleaned regularly, but manual direct entry into the pipeline for inspection and maintenance is prone to safety accidents.

[0003] At present, pipeline cleaning in dredging projects is done by directly flushing with clean water, but it cannot guarantee that long-distance pipelines are cleaned thoroughly, and it is extremely wasteful of water resources; or pipeline robots are used for pipeline cleaning, but the existing pipeline robots mainly rely on adsorption to fix on the inner wall of the pipeline during operation, and in actual use, adsorption failure is easily caused due to scale accumulation on the inner wall of the pipeline, pipeline material and other reasons, and the adsorption method is not convenient for the pipeline robot to move in the pipeline; most cleaning robots also only use cleaning brushes for cleaning, which are difficult to clean solid or hard dirt and have low cleaning efficiency.
