[0002] When transporting solid-containing liquids through pipelines, the changes in the solid content of the transported liquid, the changes in flow rate (flow velocity), the changes in ambient temperature, etc., will cause accumulation and blockage in the transport pipeline. Traditionally, when pipelines are blocked, high-pressure water flushing and external force pipe poking are often used to clean them. Such operations are likely to damage the pipelines. At the same time, due to the length of the pipelines and the location of the bends, the cleaning effect of pipeline blockage is poor. At the same time, when the pipeline is seriously blocked, it is destroyed to clear it, which makes the later maintenance cost of the pipeline high. Summary of the invention
