Desilting device of water conservancy project

Abstract

The invention discloses a desilting device of a water conservancy project. The desilting device of the water conservancy project comprises a turnover digging mechanism, a suction mechanism, a crushingmechanism and a sludge containing box, wherein the turnover digging mechanism comprises a pair of L-shaped supports which are vertically arranged and a rotating column which is horizontally arrangedin the axial direction; the suction mechanism comprises a suction cover and a stone filter screen arranged in the suction cover, and the suction cover is a circular truncated cone structure which is small in upper part, large in lower part and communicates in the axial direction; the crushing mechanism comprises an outer shell, an inner shell positioned in the outer shell, and a cutter body arranged inside the inner shell; the sludge containing box comprises a lower box body and an upper box body, wherein the lower box body and the upper box body are in sealing connection, the lower box body and the upper box body are both cylindrical structures which are vertically arranged in an axial direction. According to the device, sludge can be thoroughly cleared, the large-particle pebble hard objects are prevented from damaging a waste water pump, a pipeline cannot be blocked, the fineness of the cleared sludge is uniform, the water content is low, and the desilting device is a preferred option for preparing fertilizer.

Description

technical field [0001] The invention relates to the technical field of water conservancy projects, in particular to a dredging device for water conservancy projects. Background technique [0002] There are many rivers and lakes in our country, and the sedimentation problem is very serious. The sedimentation causes the river bed to rise, which affects flood control, threatens the safety of people's lives and property, and at the same time affects the normal performance of various functions such as drainage, irrigation, water supply, and navigation, and restricts the comprehensive utilization of water resources. , exacerbate the deterioration of the water environment, and promote the rapid and sustainable development of the environmental protection economy and society, it is necessary to improve the efficiency of the existing dredging devices. [0003] Water conservancy project is a general term for various engineering constructions built to control, utilize and protect surfac...

AI Technical Summary

Problems solved by technology

During the construction of water conservancy projects, the underwater silt cannot be cleaned and deposited on the bottom of the water, which may cause paralysis and collapse of the water conservancy project. Therefore, it is necessary to regularly dredge the drainage to ensure the smooth flow of the river. However, the existing dredging The device is not only bulky, inconvenient to move, but also inconvenient to operate and use, low and incomplete dredging efficiency, waste of manpower and material resources, and poor use effect

Moreover, the existing dredging method is to directly rely on the dredging device to suck out the silt. If hard objects are encountered, the pipeline of the dredging device will be easily blocked, which will affect the use.

In addition, in the prior art, the cleared silt is usually piled up on the bank, which affects the appearance and wastes resources
