A self-propelled raft-type river dredging device

Abstract

The invention proposes a self-propelled raft type river dredging device. It is a mobile continuous dredging device with river water power generation device as the power system, raft unit plate or its combination as the carrier, and water flow force as the self-propelled power. The present invention uses a spiral dredger with a drill bit to directly excavate the sediment in the sand bed at the bottom of the river, and uses mutually bound raft unit plates equipped with belt conveyors to form a mobile pontoon-type transportation channel, and the relay type directly removes the sediment. Sending it to the embankment solves the bottleneck problems of traditional dredging machinery such as low efficiency and difficult transportation. The floating machine combines the water retaining skirt with the waterwheel type water motor and adopts the double-walled floating cylinder, so that the buoyancy and water flow power generation capacity are both improved. The river water power generation device or power station built during the construction process can not only meet the power demand of the self-propelled raft dredging device, but also can be connected to the power grid to obtain the dual economic benefits of treating a river and leaving a power legacy.

Description

technical field [0001] The invention relates to the technical field of a self-propelled raft type river channel dredging device. Background technique [0002] With the increase of global abnormal weather, river basin floods are no longer a small probability event. Due to the long-term stagnation of sediment deposits in the middle and lower reaches of the river, the channel becomes shallower and narrower, and the flood-holding capacity deteriorates. In addition, the original flood control dams are too short and too narrow, and most of them are ridge-shaped dams stretching for more than tens of kilometers. Once a super flood occurs, flood disasters are almost inevitable. Therefore, comprehensive cleaning and deepening of river channels and construction of high-altitude all-weather flood control embankments have become the most urgent hydraulic engineering tasks. Traditional water conservancy engineering technology and equipment have high energy consumption, low efficiency, a...

Problems solved by technology

Because this river dredging ship uses a single ship-borne hydrodynamic machine, the power machine is directly connected to the dredging device, and the output is a mixture of mud and water, which makes the device have insufficient power and is inconvenient to use general-purpose machinery. And the technical defect that the dredging efficiency is not high enough, thus limiting the scope of use of the device
