They are also called water projects. Water is a precious resource that is indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flows, prevent floods and waterlogging disasters, and regulate and distribute water to meet the needs of people's lives and production for water resources. Water conservancy projects need to build dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways and other different types of hydraulic structures to achieve their goals. In the long-term process of transporting water, there will be a certain amount of silt inside the pipeline, which needs to be cleaned regularly. With regular cleaning, the inside of the pipeline will not accumulate a large amount of silt, but it still needs to be cleaned.

现有的淤泥清理装置在进行使用的过程中,由于管道内部具有大量的水,在进行清理时需要对管道进行停水操作,使得在清理的过程中影响对水进行输送,从而导致在进行操作时较为繁琐,为此,我们提出一种水利管道养护用的淤泥定期清理装置。During the use of the existing sludge cleaning device, since there is a large amount of water inside the pipeline, the pipeline needs to be shut off for cleaning, which affects the water transportation during the cleaning process, resulting in cumbersome operation. For this reason, we propose a regular sludge cleaning device for water pipeline maintenance.
