Abstract

The invention discloses a height-adjustable protective fence for a water conservancy project. The height-adjustable protective fence for the water conservancy project comprises a first base and a second base, wherein the upper surface of the first base and the upper surface of the second base are separately fixedly connected with a first supporting leg and a second supporting leg; an upper connecting rod and a lower connecting rod are fixedly connected between the first supporting leg and the second supporting leg; the upper connecting rod is fixedly connected with the lower connecting rod through a supporting rod; and a bearing is clamped on the surface of the upper connecting rod. By rotation of a screw, threads on the surface of the screw pushes a toothed rail to move in the vertical direction, the track teeth are subjected to thrust of the screw and move in the vertical direction so as to drive a handrail to be adjusted vertically, under the limiting effect of a push rod, the firstsupporting leg and the second supporting leg, the handrail only can move in the vertical direction, under the limiting effect of a chute and a clamping tooth, the push rod is prevented from being separated from the inside of the first supporting leg and the inside of the second supporting leg, and by synergistic effect of various components, stepless height adjustment of the handrail in the vertical direction is implemented.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a height-adjustable protective fence for water conservancy engineering. 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 engineering. 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 we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's life and production for water resources. Water conservancy projects need to build different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, canals, rafts, and fishways to achieve their goals. [0003] Since the water conservanc...
