The invention relates to a power pipeline dredging device and method based on high-pressure water. The device comprises a driving part, a negative-pressure part, a composite pipe, a jet pump, a sprayhead and a high-pressure water pump. According to the scheme, the spray head is conveyed to the blocked position of an underground pipeline through the composite pipe, then the driving part and the negative-pressure part are started, the driving part can drive the high-pressure water pump to work, the high-pressure water pump pressurizes water to form two strands of high-pressure water, and one strand of high-pressure water is sprayed out of the spray head after passing through one pipe body on the composite pipe, so that the underground pipeline is dredged; and the other stream of high-pressure water enters a diffusion pipe on the jet pump to form high-pressure fluid, and dredged blockage materials sequentially pass through a throat pipe on the jet pump, the diffusion pipe on the jet pumpand the first pipe body and then are pumped away from a fifth water outlet in the negative-pressure part, and as the high-pressure fluid is formed in the diffusion pipe in the direction from a nozzleof the jet pump to the diffusion pipe, the dredged blockage materials can be more conveniently pumped away through the negative-pressure part.
Description
technical field [0001] The invention relates to the technical field of pipeline dredging, in particular to a high-pressure water-based power pipeline dredging device and method. Background technique [0002] With the development of the city, the urban underground space is becoming more and more crowded, and it has become a trend to use pipelines to lay electricity and other underground pipelines. However, due to improper maintenance, many backup power pipelines are often blocked by sand and need to be dredged before they can be used. [0003] At present, the main pipe-through method is to use a pipe threader to dredge. After the pipe threader passes through the pipe, a hemp rope is tied, and the steel cage is dragged by the hemp rope to move in the pipe, thereby dragging out the silt in the pipe. This method has low working efficiency and can only dredge the not very serious situation that the silt accumulated in pipelines is blocked, and the pipelines that can be dredged a...
