A municipal road safety protection device

Abstract

The invention relates to the technical field of road safety facilities, in particular to a municipal road safety protection device. The municipal road safety protection device comprises a plurality of vertical rods, an anti-collision protection body is arranged between every two vertical rods, and the anti-collision protection bodies and the vertical rods are connected through elastic supporting rods; two sides, facing a road, of each of the anti-collision protection bodies are provided with collision sensors, two groups of air bag modules which are electrically connected with the collision sensors are arranged in the anti-collision bodies; each group of air bag modules comprises an air bag, a gas generator used for enabling the air bag to expand, and an air bag shell for installing the air bag. The device provided by the invention has the advantages of being capable of reducing rebound impact on a collision object, rapidly popping-up the air bag during collision, and preventing damage to a vehicle housing, and is convenient to dismount and mount.

Description

technical field [0001] The invention relates to the technical field of road safety facilities, in particular to a municipal road safety protection device. Background technique [0002] With the continuous development of society, people's living standards continue to improve, and the number of motor vehicles continues to increase. In urban roads, guardrail devices are often used to divide the roads to ensure driving safety and smooth traffic. The current guardrails are welded with ordinary steel bars, which are complex to install, and light impacts will cause the guardrails to deform or break, not only failing to protect the vehicle and passengers, but also scratching the car, and even causing secondary damage to passengers. [0003] The patent with the publication number CN204959654U discloses a kind of anti-collision road guardrail, comprising a column, a base, an upper beam and a lower beam, the base includes a shell and concrete, the inner cavity of the shell is filled wi...

[0003] The patent with the publication number CN204959654U discloses a kind of anti-collision road guardrail, comprising a column, a base, an upper beam and a lower beam, the base includes a shell and concrete, the inner cavity of the shell is filled with concrete, and the base A column is installed on the top, a lamp tube is installed in the inner cavity of the lampshade, a solar panel is arranged on the top of the lampshade, an upper beam and a lower beam are respectively installed at the upper and lower ends of the column, and the left and right ends of the upper beam and the lower beam are Both are equipped with springs. The anti-collision road guardrail, by setting springs at both ends of the upper beam and the lower beam, can play a buffering role on the guardrail during the collision process, thereby reducing the impact force and affecting the vehicle and the guardrail. All have a certain protective effect, but only use springs, which play a very small protective effect, and the installation of the guardrail is complicated and has few auxiliary functions.
