technical field

The invention relates to the technical field of water conservancy engineering equipment, in particular to an inner wall dredging device for water supply and drainage pipes of water conservancy projects.

Background technique

A water conservancy project is a project built for the purpose of controlling and deploying natural surface water and groundwater to achieve the purpose of eliminating harm and increasing profits. Also known as water engineering. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent flood disasters, and adjust and distribute water to meet the needs of people's lives and production for water resources. Water conservancy projects require the construction of different types of hydraulic structures such as dams, embankments, spillways, sluice gates, water inlets, channels, ferries, rafts, fishways, etc., to achieve their goals.

Water supply and drainage pipeline engineering is a pipeline system engineering for conveying and distributing industrial water supply and drinking water and collecting, conveying and discharging industrial wastewater, domestic sewage and rainwater. Water supply and drainage pipeline engineering is an integral part of the water supply and drainage system and plays an important role in the entire water supply and drainage system. It includes the pipeline system itself and various structures on the pipeline system.

During the use of water supply and drainage pipelines in water conservancy projects, after a period of use, some sediment will be generated in the pipeline, and the sediment needs to be dredged to prevent the sediment from clogging the pipeline and affecting the normal use of the pipeline. When cleaning water conservancy pipes, manual cleaning is mostly used. The inner wall of the pipe is cleaned with a brush. The cleaning efficiency is low, and the manual cleaning distance is short. After the cleaning is completed, it is necessary to use a water pipe to clean Cleaning the inside of the pipeline is time-consuming and labor-intensive, and the cleaning efficiency is low. For this reason, we propose a dredging device for the inner wall of water supply and drainage pipelines in water conservancy projects.
