Safety fence of flood discharge river channel

Abstract

The invention discloses a safety fence of a flood discharge river channel, and relates to the technical field of fences. The safety fence comprises symmetrically arranged stand columns, a first cross rod and a second cross rod are respectively arranged between the stand columns, the first cross rod is located above the second cross rod, and a plurality of handrails are inserted into the first cross rod and the second cross rod in a penetrating mode; and rotating shafts are arranged on the two sides of the second cross rod respectively and movably inserted into the stand columns in a penetrating mode; grooves are formed in the two ends of the first cross rod respectively, the stand columns are provided with containing cavities matched with the grooves, baffle rings are arranged in the containing cavities, and T-shaped rods are inserted into the baffle rings in a penetrating mode. The problem that a large number of crops gather in front of the fence during flood discharge is solved, meanwhile, the problem that the fixed fence is destroyed due to the water blocking phenomenon is solved, safe operation of a project can be guaranteed in the non-flood season, personnel are prevented from mistakenly entering or falling into a project river, the fence can be put down during flood discharge in the flood season, the water blocking area is reduced, and the smoothness of the flood passage is ensured.

Description

technical field [0001] The invention relates to the technical field of guardrails, in particular to a safety guardrail for a flood channel. Background technique [0002] Fences are a protective facility that can be seen everywhere in our lives. They are mainly used for the protection and protection of personal safety and equipment and facilities in residences, roads, river banks, commercial areas, and public places. [0003] At present, the works in the flood channel need to install protective fences on the traffic bridges, wing walls and slope protection along the river. Traditional concrete guardrails, chains and anti-collision piers or metal guardrails all have problems that either the dense guardrails affect flood discharge, or the small water blocking surface does not meet the safety protection standards. In addition, there will be a large number of crops falling with the water during the flood discharge period, and it is very easy to gather in front of the guardrail, ...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the problems in the related technologies, the present invention proposes a safety guardrail for the flood channel, which solves the problem of a large number of crops gathering in front of the guardrail during the flooding period, and also solves the problem of washing away the fixed guardrail caused by the phenomenon of water blocking , to meet the technical problems of ensuring the safe operation of the project and preventing people from entering or falling into the diversion channel of the project during the non-flood season, and that the fence can be brought down during the flood season to reduce the water blocking area and ensure the smooth flow of the flood channel
