Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline cleaning equipment, in particular to a pipeline cleaning device with high efficiency of scale removal. BACKGROUND

[0002] In the industrial production fields of petroleum chemical industry, food processing, and the urban infrastructure of water supply and drainage, heat supply, etc., pipelines are the core components for fluid transportation. However, after long-term use, the inner wall of the pipeline is prone to accumulate various types of dirt such as oil stains, rust scale, etc. These dirt not only narrows the flow area of the pipeline and increases the resistance of fluid transportation, but also may cause safety hazards such as pipeline corrosion and leakage, therefore, it is necessary to use cleaning robots to clean the pipeline professionally to ensure its normal operation. However, the water mist generated by the high-pressure water jet or the agent flushing during the cleaning of the cleaning robot is easy to adhere to the camera of the robot, which makes it difficult for the operator to clearly observe the internal conditions of the pipeline and accurately judge the cleaning progress and effect, thereby affecting the work efficiency. At the same time, the robot is usually provided with a bottom sewage suction port, but the sewage generated during cleaning is mixed with large impurities such as oil stains and clumps. If these impurities directly enter the sewage discharge channel, they are easy to accumulate in the bottom sewage suction port or the sewage pump, causing channel blockage and sewage pump jamming, and ultimately interrupting the sewage discharge. And for wider pipelines, even if the sewage suction port is working normally, part of the sewage will still flow out of the pipeline under the action of gravity, not only polluting the working environment, but also possibly damaging the surrounding equipment, increasing the workload of subsequent cleaning and maintenance.
