A kind of unpowered dredging device for river course

Abstract

The invention relates to the technical field of dredging equipment, and discloses a non-powered dredging device for river channels, which includes a ship, the ship is connected to a floating platform through a water bag, and a return spring is arranged between the ship and the floating platform. The water bag is extruded by the boat and the floating platform away from and near to make the water bag absorb and discharge water in one direction. There is no power dredging device for the river channel. When the water flow and tide are used, the ship and the floating platform are close to and far away from each other, and the water is stored in the water bag. When the ship and the water bag are close, the extruded water is used to drive the movement of the equipment. The overall power is large and the driving ability is strong. Secondly, through the three-stage conveying, the requirements for the strength of the conveying power are further reduced, and the conveying capacity of the sludge is enhanced without pollution and waste. In addition, through the three-stage setting, Its applicability is enhanced, and the river channel of any depth can achieve better results. At the same time, the water wheel and the screw conveying rod are relatively common components, and the overall structure is simple and easy to maintain.

Description

technical field [0001] The invention relates to the technical field of dredging equipment, in particular to an unpowered dredging device for a river channel. Background technique [0002] Due to the long-term siltation of sediments in the middle and lower reaches of the river, the channel becomes shallower and narrower, and the flood capacity becomes poor, which increases the risk of floods and reduces the navigation ability of ships. Carry out dredging. [0003] Usually, high-power driving equipment is required to lift the river bottom silt to the cabin. On the one hand, the overall structure is complex and the cost is high. On the other hand, the existing ships are usually driven by diesel oil, which generally leaks and pollutes the river environment. At the same time, the exhaust gas produced by diesel drive will also pollute the environment. [0004] Secondly, different river sections often need to be dredged during dredging, and the location needs to be changed freque...

Problems solved by technology

[0003] Usually, lifting the river bottom silt to the cabin requires high-power driving equipment. On the one hand, the overall structure is complex and the cost is high. On the other hand, the existing ships are usually driven by diesel oil, which generally has leakage and pollutes the river environment. At the same time, the exhaust gas generated by diesel driving will also pollute the environment

[0004] Secondly, during dredging, it is often necessary to dredge different sections of the river, and the location needs to be changed frequently. Therefore, a simple structure, convenient on-site assembly, and high reliability are required. Not convenient
