Dredging device for river channel at estuary entering sea

Abstract

The invention relates to the technical field of water conservancy projects, in particular to a river channel desilting device at a sea-entering estuary, which comprises an equipment base, a support hanging bracket mounted on the equipment base, and an operation rack erected on the support hanging bracket, the operation rack is movably installed on the supporting hanging bracket through a hanging bracket seat, and the operation rack swings with the hanging bracket seat as the axis. A lower edge support is arranged on the operation rack, the lower edge support is installed on the operation rack in a telescopic mode, a desilting base is installed at the bottom end of the lower edge support, a crushing device is rotatably installed on the desilting base, and the crushing device is used for scattering river sludge; the supporting hanging bracket is further externally connected with a back-flushing assembly, a pipeline of the back-flushing assembly extends into the deep position of the river channel along the lower edge support, and the tail end of the pipeline is connected with the crushing device. The dredging device can deeply destroy a sludge layer, crush sludge and effectively dredge under the condition that the ecology is not affected.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a dredging device for river channels at estuaries entering the sea. Background technique [0002] A large amount of silt often accumulates on the riverbed of the river, which will accumulate on the riverbed after sedimentation, which will have a serious impact on the ecology of the entire river, causing the liquid level of the river to rise, so it needs to be cleaned regularly; long-term river silt accumulation , It will even affect the traveling ships, and accidents are prone to occur during the journey, causing irreparable losses. [0003] In the prior art, positioning piles are arranged on the hull, a suspension frame is installed at the front end of the hull, and a dredging device is arranged on the suspension frame, and the mud deposited at the bottom of the river is stirred into turbidity through a mechanical structure, thereby achieving dredging. The...

AI Technical Summary

Problems solved by technology

However, the accumulation of silt at the mouth of the sea is generally serious, and the existing dredging equipment cannot effectively penetrate deep into the silt. It is often necessary to use large-scale dredging equipment to excavate the river, but the excavation will seriously damage the ecological stability of the entire river. ; Therefore, how to effectively carry out dredging without affecting the ecology is the direction that water conservancy engineering technology needs to study now
