Underwater plowing device for river regulation and restoration

Abstract

The invention discloses an underwater plowing device for river regulation and restoration. The underwater plowing device comprises a body and is characterized in that a water flow driving mechanism is arranged on the upper portion of the interior of a shell, a plowing mechanism is arranged on the lower portion of the interior of the shell, a separating mechanism is arranged on the portion, located on one side of the plowing mechanism, of the lower portion of the interior of the shell, the water flow driving mechanism comprises a clamping assembly and a centripetal extraction assembly, the clamping assembly is arranged on the outer side of the centripetal extraction assembly, and the clamping assembly is in transmission connection with the centripetal extraction assembly; the plowing mechanism comprises a soil loosening assembly and a soil ploughing assembly, the soil loosening assembly is arranged on one side of the soil ploughing assembly, and the soil loosening assembly and the soil ploughing assembly are fixed; and the separating mechanism comprises an extraction assembly, and the extraction assembly is in transmission connection with the soil ploughing assembly. The underwater plowing device has the characteristics that when the water flow speed is high, a riverbed can be plowed in time, the depth of the riverbed is increased, flood is avoided, and garbage deposited at the bottom of the riverbed is collected.

Description

technical field [0001] The invention relates to the technical field of river regulation, in particular to an underwater plowing device for river regulation and restoration. Background technique [0002] River training (river improvement; river regulation) is also called "river bed preparation". Engineering measures for controlling and transforming river courses. Scouring and silting often occur in natural rivers, which are prone to water damage and hinder the development of water conservancy. In order to meet the requirements of eliminating troubles and making profits, appropriate measures must be taken to regulate the river course, including projects such as regulation, dredging and revetment. [0003] Harnessing river courses has been a very important and difficult task since ancient times. People often raise the embankment passively when the flood floods, and the floods in the flood season continue to carry mud and sand down the river every year, which makes the river ...

AI Technical Summary

Problems solved by technology

However, hard river courses have greatly restricted the ecological restoration of urban river courses and reduced the self-purification ability of river courses. Moreover, hard river courses are built on the original river silt, with the upper part being hard and the off-duty part being soft silt. There is a big risk in reaching the standard. In the prior art for hard river channel cleaning and underwater plowing technology, it is difficult to plow hard soil alone. Hard soil and silt are often mixed together for treatment. In rainy weather or When the water velocity is high, it is easy to cause a large amount of water and soil loss to destroy the original hard river bottom structure
