Abstract
Description
Technical Field
[0001] This utility model belongs to the field of river dredging, specifically relating to a river dredging device. Background Technology
[0002] River dredging generally refers to the management of river channels and is a type of water conservancy project. Using mechanical equipment, silt deposited on the riverbed is agitated and dispersed into turbid water, thus clearing the river. River siltation has increasingly affected the normal functioning of various river systems, including flood control, drainage, irrigation, water supply, and navigation. To restore the normal function of rivers and promote rapid and sustainable economic and social development, river dredging projects are carried out. Through these projects, rivers become deeper and wider, the water becomes clearer, and the production and living conditions of the local people are significantly improved. However, during water conservancy project construction, large amounts of silt accumulate on the riverbed. This silt, after settling, accumulates further, and in severe cases, can cause the river to become an above-ground channel, as seen in some sections of the Yellow River. Furthermore, the silt can damage the entire river's ecosystem, necessitating regular cleaning.
[0003] Patent document CN208563415U discloses a river dredging device, including a loading box, a main support, a movable base, a support rod, a drive motor, a self-priming sewage pump, a mesh cage, a stirring blade, and a sewage pipe. The main support is located on the outer wall of the left end of the loading box, and the movable base is located on the outer wall of the main support. The support rod is located on the left end of the movable base. The drive motor and the self-priming sewage pump are respectively located on the upper end of the support rod, and the mesh cage is located on the lower end of the support rod. The stirring blade is placed in the mesh cage via a shaft mounted on the drive motor. The sewage pipe is connected to the self-priming sewage pump in the inner cavity of the right end of the mesh cage. A filter box is located on the upper right side of the loading box. This utility model, with the drive motor and self-priming sewage pump on the upper end of the support rod, and the mesh cage, stirring blade, and sewage pipe at the lower end of the support rod, can quickly mix and extract river silt and water for screening and treatment, achieving river cleaning and environmental beautification. It is practical and suitable for widespread promotion and use.
