Plain river bottom silt clearing device and clearing method thereof

Abstract

The invention discloses a plain river bottom silt clearing device and a clearing method thereof. The plain river bottom silt clearing device comprises a boat, wherein a driving device is arranged at the bottom of the boat, a lifting assembly is arranged at the front side of the boat, a clearing assembly is slidingly connected with the side, away from the boat, of the lifting assembly, a storage device is arranged at the front side of the top surface of the boat, a balance weight water tank is arranged at the rear side of the top surface of the boat, the storage device communicates with the balance weight water tank, and the clearing assembly communicates with the storage device. The method comprises the following steps: (1) conducting preparation before desilting; (2) stacking silt centralizedly; (3) conducting desilting; (4) storing the silt; and (5) conducting desilting on residual desilting points. According to the plain river bottom silt clearing device and the clearing method thereof, through the clearing assembly, river bottom silt at different depths can be cleared, the clearing assembly is used for clearing the silt at the river bottoms, meanwhile, the silt at the river bottoms is transported into the storage device, the silt placed in the storage device naturally sinks, and river water located above the storage device is transported into the balance weight water tank at the rear end of the boat, so that balance of the boat is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of desilting equipment, and in particular relates to a device for cleaning mud at the bottom of plain river courses and a cleaning method thereof. Background technique [0002] River dredging generally refers to the treatment of rivers, which belongs to water conservancy projects. Through mechanical equipment, the silt deposited on the bottom of the river is blown and stirred into turbid water, which flows away with the river, thus playing a role in dredging. River siltation has increasingly affected flood control and drainage. In order to restore the normal function of the river and promote the rapid and sustainable development of the economy and society, the dredging and dredging project of the river will be carried out, so that the river will become deeper and wider, the river will become clearer, and the people The production conditions and living environment have been significantly improved.

AI Technical Summary

Problems solved by technology

[0003] At present, domestic dredging methods mainly use excavators or ship-borne mud-grabbing equipment for mud cleaning. However, since the mud is located at the bottom of the river, the mud in the mud-grabbing equipment is easily washed by the river during the process of grabbing the mud and transporting it to the hull. open, thus greatly reducing the dredging efficiency. At the same time, after the silt grabbing equipment grabs the river bottom silt onto the ship, the silt contains various harmful substances and relatively strong odor, which causes discomfort to the crew on board.
