River and lake contaminated bottom sediment ecological desilting ship

Abstract

The invention relates to the technical field of river and lake desilting, in particular to a river and lake contaminated bottom sediment ecological desilting ship comprising a ship body, conveying pipes, conical hoppers, suction pumps, rotation drive devices, connection devices and [-shaped rotation frames. Rectangular frames are fixed to the two sides of the ship body. A slide table is arranged on each rectangular frame in a sliding manner. A winch is fixed to each slide table. A vegetation protection device is hoisted on each winch through a steel wire rope. A mechanical arm is fixed to eachvegetation protection device. The upper ends of the conveying pipes are fixedly connected with the slide tables. The lower ends of the conveying pipes are fixedly connected with the movable ends of the mechanical arms. The drive ends of the rotation drive devices are fixedly connected with the connection devices. A clamping jaw used for grabbing or releasing the corresponding [-shaped rotation frame is installed on each connection device. Winding columns which extend downwards and are used for winding plant are arranged at the two ends of each [-shaped rotation frame. The ship body rotates todrive the [-shaped rotation frames to rotate, and therefore the strip-shaped plant can be curled, the coverage area of plant bodies can be minimized, and the aim of protecting the plant is achieved.Meanwhile, precise positioning can be achieved during desilting, and the river and lake contaminated bottom sediment ecological desilting ship can avoid river bottom vegetation.

Description

technical field [0001] The invention relates to the technical field of river and lake dredging, in particular to an ecological dredging ship for polluted bottom mud of rivers and lakes. Background technique [0002] Each river and lake is an independent ecological circle. In order to ensure the cleanliness of the environment, the bottom of the river and lake should be regularly dredged. However, due to the huge workload of dredging, mechanical equipment will be used to clean it. Most of the traditional cleaning equipment is of the conveyor belt type or directly sucks the sludge through the suction pipe, but does not take into account the vegetation at the bottom of the river. When the sludge is sucked, it will cause damage to the plants at the bottom of the river and lake, thereby affecting the ecological balance. At the same time, the existing dredging equipment does not have the function of underwater movement, and its position can only be adjusted by moving the hull, whic...

Problems solved by technology

[0004] The above-mentioned patent can effectively salvage and clean up organisms through the function of the ecological salvage device, but at the same time, due to its mechanism characteristics, the plants at the bottom of the river and lake will be salvaged together, causing damage to the plants, and it cannot be dredged. While protecting plants, it directly affects the ecological balance of rivers and lakes

And it can only adjust the salvage position through the movement of the hull, which cannot achieve accurate positioning and the cleaning efficiency is low
