Flashboard for water conservancy project

Abstract

The invention provides a flashboard for a water conservancy project and relates to the field of water conservancy projects. The flashboard is used for being mounted on a gate system of the water conservancy project, the gate system comprises a water conservancy body and a gate mechanism, the water conservancy body is provided with a navigation opening, the gate mechanism is used for opening or closing the navigation opening and comprises a clearing mechanism and the flashboard, a first sliding groove and a second sliding groove are formed in the two side walls of the navigation opening correspondingly, the first sliding groove is matched with the flashboard, the second sliding groove is matched with the clearing mechanism, the flashboard is slidably embedded in the first sliding groove, and the clearing mechanism is slidably embedded in the second sliding groove and used for clearing floats on the two sides of the flashboard. According to the flashboard for the water conservancy project, the flashboard is driven by a piston cylinder, consumed energy is reduced greatly, power of the piston cylinder is quite sufficient, and the service life is long. In addition, the gate system is provided with the clearing mechanism, the floats adhering to the periphery of the flashboard can be fished completely, and the situation that a downstream water body is polluted during gate opening is avoided.

Description

technical field [0001] The invention mainly relates to the field of water conservancy engineering, in particular to a gate for water conservancy engineering. Background technique [0002] In water conservancy projects, in order to rationally utilize water conservancy resources for power generation, rivers are usually divided through gates, and the gates of the gates are mainly used to realize the functions of water retention and discharge. Closing the sluice gates can block floods, keep out tides, store water and raise the upstream water level to meet the needs of upstream water intake or navigation. When the gate is opened, flood discharge, waterlogging, sand flushing, water intake or flow can be adjusted according to the needs of downstream water use. Gates are widely used in water conservancy projects, and are mostly built in river courses, canal systems, reservoirs, lakes and coastal areas. [0003] Because the impact force of water and the energy of water pressure are...

AI Technical Summary

Problems solved by technology

This device completely removes the protruding buttress on the surface of the dam body, thereby solving the problem of water blocking and garbage blocking of the gate leaf and the buttress when the gate is fully opened, and improving the flow capacity, but it directly Let the garbage flow downstream, causing pollution, and its navigability is poor, and it also takes a lot of energy to open and close the gate
