Description
Technical Field
[0001] The utility model relates to the technical field of pipeline desilting nozzles, in particular to a special nozzle for desilting urban underground pipelines. Background Art
[0002] Urban underground pipelines are pipes laid underground for transporting liquids, gases or loose solids. In ancient China, underground drainage pipes made of fired clay were already used. In the Ming Dynasty, when Beijing was the capital, bricks and stone strips were used extensively to build underground drainage pipes. They were about 1 meter wide and 2 meters high. There are many types of modern underground pipelines, including circular, elliptical, semi-elliptical, multi-circular, oval, rectangular (single-hole, double-hole and multi-hole), horseshoe-shaped and other cross-sectional forms. They are made of steel, cast iron, concrete, brick, stone, asbestos cement, clay, plastic, fiberglass and other materials. When desilting urban underground pipelines, special nozzles are needed to flush out the silt in the underground pipelines.
[0003] According to Chinese patent CN214657662U, a municipal pipeline desilting device is provided, in which a cleaning head is inserted into the interior of the pipeline (the outer diameter of the cleaning head is slightly smaller than the inner diameter of the pipeline), a high-pressure water pump cooperates with a water pipe and a nozzle to spray out a high-pressure water flow, and the sludge is washed down by the high-pressure water flow, and an electric push rod can drive the cleaning head to move forward, and the front end of the inner wall of the cleaning head is inclined to facilitate the flow of sludge. When the cleaning head moves, part of the sludge can be squeezed into the rubber cover, and at this time the sludge pump cooperates with the sewage pipe to discharge the sludge into the sludge tank, thereby realizing pipeline desilting. The entire operation is convenient and fast, and the work efficiency is effectively improved.
[0004] The nozzle of the above-mentioned device sprays inside the cleaning head to clean the silt on the inner wall of the pipe. When encountering a severely blocked pipe and stones mixed in the silt, it is not convenient to flush the silt clean only by the pressure of the nozzle, which not only prolongs the working time but also affects the subsequent use of the pipe, reducing the practicality of the device. Therefore, a special nozzle for desilting urban underground pipes is proposed to solve the above problems. Utility Model Content

The utility model solves the problem that when cleaning the existing pipeline silt, the silt is only cleaned by water sprayed from the nozzle. When encountering a severely blocked pipeline, the cleaning efficiency is easily reduced, affecting the normal use of the subsequent pipeline.
