Hydraulic engineering device for river flow limitation

Abstract

The invention discloses a hydraulic engineering device for river flow limitation. The hydraulic engineering device comprises a supporting pipe, wherein a water baffle is fixedly connected to the sideface of the supporting pipe; a flow limiting plate is connected into the water baffle in a sliding mode; an extrusion rod is fixedly connected to the side, close to the supporting pipe, of the flow limiting plate; a bearing wheel is rotationally connected to the side, away from the flow limiting plate, of the extrusion rod; a middle shaft is arranged above a baffle; a centrifugal wheel is fixedlyconnected to the side face of the middle shaft; a centrifugal rod is arranged on the side face of the centrifugal wheel in a penetrating mode; an extrusion block is arranged on the side face of the middle shaft in a penetrating mode; an ejector rod is connected to the side face of the extrusion block in a sliding mode; a lever is rotationally connected to the side, away from the extrusion block, of the ejector rod; and a magnetic block is rotationally connected to the bottom of the lever. According to the hydraulic engineering device for river flow limitation, through the cooperative use of awater blocking wheel and the middle shaft, the effects that the flow intercepting surface can be adjusted according to the change of the flow speed of a river, and the flow stability of the river is guaranteed are achieved.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a water conservancy engineering equipment used for limiting the flow of a river. Background technique [0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits, also known as water projects. Water is an indispensable precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can water flow be controlled, floods prevented, and water volume adjusted and distributed to meet the needs of human beings. People's living and production needs for water resources. [0003] In water conservancy projects, it is often necessary to restrict the flow of the river to ensure the smooth flow of the downstream. The existing method of limiting the flow is to pile u...
