Foldable information board suitable for flood discharge atomization area

Abstract

The invention relates to a foldable information board suitable for a flood discharge atomization area, which comprises an information board body, support legs on two sides of the information board body are arranged on the ground through bases on two sides, power mechanisms, slideways and sliding blocks are arranged in the bases on two sides, the power mechanisms are connected with the sliding blocks, the sliding blocks are arranged on the slideways in a sliding manner, and connecting rods are arranged on the sliding blocks, the lower end of the connecting rod is hinged with the slider, the upper ends of the connecting rods are hinged with the supporting legs on the corresponding sides of the information board body; the supporting legs on the corresponding sides of the information board body are hinged to the bases on the corresponding sides. The electric push rod pushes the sliding block to slide, the sliding block drives the information board body to generate angle change through the connecting rod until the information board is attached to the ground, and folding of the information board is achieved. When no flood is discharged, the information board is in a vertical state; before flood discharge, the information board is folded through the electric push rod, the surface of the information board is basically parallel to the wind direction, the wind load on the surface of the information board is greatly reduced, and the danger that an information board rod piece is broken by storm wind is avoided.

Description

technical field [0001] The invention relates to the technical field of flood discharge atomization area protection, in particular to a foldable information card suitable for flood discharge atomization area. Background technique [0002] When the discharge structures of water conservancy and hydropower projects discharge floods, unnatural strong winds, rainfall and fog will form in the local area downstream of the hub, which may affect or even harm the hub buildings, cross-strait traffic and slope stability, and affect the ecology of the flood discharge atomization area environment and the normal life of the surrounding residents. [0003] The flood discharge atomization produces a strong water tongue wind, and trees and information signs on the river bank slope in the flood discharge atomization area are often blown away by the wind and knocked down. For example, the tailwater platform of Shuibuya Hydropower Station is located in the area strongly affected by flood dischar...

AI Technical Summary

Problems solved by technology

This structure reduces the force effect of wind force on the information board to a certain extent, but in the strong influence area of ​​flood discharge and atomization, the information board generally has a higher center of gravity, and the information board in the unventilated part still bears the action of the storm, which cannot avoid the upper information board being damaged. Bending or even breaking
