Description
Technical Field
[0001] This utility model relates to the field of dredging and unblocking technology, specifically a dredging and unblocking device for municipal pipeline networks. Background Technology
[0002] In my country, municipal infrastructure refers to various buildings, structures, and equipment set up within the planning and construction scope of urban areas and towns (townships) to provide paid or free public goods and services to residents based on government responsibilities and obligations. The construction of various public infrastructure supporting urban life falls under the category of municipal engineering, such as common urban roads, bridges, subways, underground pipelines, tunnels, waterways, rail transit, sewage treatment, and garbage disposal projects. Among them, underground pipeline projects include common water supply, drainage (including rainwater and sewage), power supply, communication, gas supply, and heating pipelines, as well as underground pipelines for special purposes and civil defense passages. Currently, urban sewage is mainly diverted and centrally discharged through underground pipelines. Impurities in sewage can easily accumulate in underground pipelines, leading to blockages. Therefore, underground pipelines need to be dredged periodically. However, currently, dredging operations are usually carried out manually by entering the pipelines. The poor air quality inside the closed pipelines for a long time can easily cause workers to suffer from oxygen deficiency, leading to safety accidents.
[0003] In existing technologies, when using mechanical winches to dredge sludge, the mechanical winches are easily entangled by difficult-to-clean materials such as hair and plastic at the blockage points inside the pipe network, resulting in reduced dredging efficiency. At the same time, a large amount of sludge adhering to the inner wall of the pipe network during dredging can easily cause secondary blockages in the pipe network. Utility Model Content
[0004] The purpose of this utility model is to provide a dredging and unblocking device for municipal pipelines. By using this device, the problems of hair, plastic and other difficult-to-clean materials in the blockage of the pipeline can easily get tangled in the mechanical winch, reducing the efficiency of unblocking. At the same time, a large amount of sludge adhering to the inner wall of the pipeline during unblocking can easily cause secondary congestion.
