Description

Technical Field

[0001] The utility model relates to the technical field of river channel regulation, in particular to a river channel regulation and silt removal device. Background Art

[0002] River siltation has increasingly affected the normal performance of various functions such as flood control, drainage, irrigation, water supply, and navigation. In order to restore the normal functions of the river and promote the rapid and sustainable development of the economy and society, river dredging projects are carried out. River dredging is of great significance:

[0003] 1. Increase the capacity of the river. The accumulation and sedimentation of silt will reduce the capacity of the river, affect the smooth flow of water, and even cause floods. Desilting can effectively increase the capacity of the river, improve hydrological conditions, and reduce the occurrence of floods;

[0004] 2. Improve the water quality of rivers. Sediment in rivers will absorb and accumulate pollutants, causing water quality to deteriorate. Desilting can reduce sediment accumulation and improve the cleanliness and transparency of water bodies.

[0005] During river dredging, some silt has been deposited for a long time and has a high density, so it needs to be broken up, otherwise it will affect the dredging efficiency. Utility Model Content

[0006] The utility model aims to solve the shortcomings in the prior art and proposes a river channel regulation and silt removal device.

[0009] Preferably, the mud conveying mechanism includes a mounting seat installed at the input end of the pump body, the mounting seat is a cross structure, the ends of the mounting seat are installed with driving units, and the output end of the driving unit is provided with stirring blades at equal angles.

[0010] Preferably, the side wall of the stirring blade away from the rotation center is provided with teeth and claws.

[0011] Preferably, the lifting structure comprises a winch arranged on the floating structure, a pulley structure is arranged on the vertical frame, and a pull line of the winch passes around the pulley structure and is connected to the pump body.

[0012] Preferably, an electric wire roller is provided on the floating structure, and the waterproof cable is wound around the electric wire roller.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the winch in the utility model controls the depth of the pump body and the mud conveying mechanism. After reaching the silt layer, the driving unit drives the stirring blades and the claws to push the silt to the center. The pump body extracts the accumulated silt and discharges it to a designated place through a mud discharge pipe. The floating structure moves on the water surface under the drive of the power structure to achieve dredging of different positions of the river channel, ensuring efficient dredging.
