Description

Technical Field

[0001] The utility model relates to the technical field of pipeline dredging and blockage removal, in particular to a pipeline dredging and blockage removal device for water conservancy projects. Background Technique

[0002] The pipelines of water conservancy projects are key facilities for realizing the rational allocation, transportation and discharge of water resources. They can transport water from the water source to the places in need, such as farmland irrigation, urban water supply and hydropower stations. In flood control and drainage, the pipelines also play an important role in timely discharging the excess water and ensuring the safety of people's lives and property.

[0003] Over time, the sediment and debris carried in the water will gradually settle at the bottom of the pipelines of water conservancy projects, forming a silt layer. Especially in areas with slower water flow velocities, the siltation problem is more serious. These silt deposits will not only reduce the flow cross-section of the pipelines and lower the water conveyance efficiency, but also cause local corrosion of the pipelines and shorten the service life of the pipelines. Some larger solid debris will accidentally enter the pipelines and cause blockages. Once the pipelines are blocked, it will not only affect the normal operation of water conservancy projects, but also pose a safety hazard of floods.

[0004] In modern society, there are manual cleaning and mechanical cleaning for dredging and detoxification. Manual dredging has a large labor intensity, low efficiency and certain safety risks. Although mechanical dredging has improved the efficiency to a certain extent, the existing dredging devices have problems such as complex structures, inconvenient operation, unsatisfactory dredging effects and insufficiently fast efficiency, and it is difficult to meet the needs of pipeline dredging and blockage removal.
