Abstract

The invention discloses a magnetic type safety guardrail. The guardrail comprises a plurality of stand columns, and the lower ends of the stand columns are fixedly connected with balance weight bases.The guardrail has the following advantages: once a vehicle collides with the guardrail, the side part of a vehicle drives a plurality of rotary drums to quickly rotate circumferentially, so the impact force of the vehicle on the front surface is weakened, and is converted into tangential force along one side of a rotary drum in the connecting rod direction, meanwhile, a conductive liquid in a hydraulic cavity generates vortex under the centrifugal effect, the overall height of the conductive liquid is increased, and the conductive liquid is in contact with conductive plates and switches on acircuit where a plurality of electromagnetic rods, the two conductive plates and an external power supply are located; and a vehicle shell is generally made of a ferromagnetic material, and a electromagnetic rod generates magnetic attraction force to the vehicle to drag the vehicle to move in the direction of the connecting rod, so the contact time between the vehicle and the rotary drum is prolonged, the braking acting force between the vehicle and the ground is improved, the conductive liquid is thrown out and sprayed to the vehicle through liquid throwing holes under the centrifugal effect,the fire preventing and extinguishing effect is achieved, and larger traffic accidents caused by fire are avoided.

Description

technical field [0001] The invention relates to the technical field of road safety, in particular to a magnetic attraction type safety guardrail. Background technique [0002] The existing road safety guardrail generally adopts a fence structure to isolate two-way lanes and bicycle lanes. However, when in use, the mechanical strength of the safety guardrail is insufficient. Once the vehicle rushes to the safety guardrail under various factors, the vehicle may Breaking the safety guardrail directly will damage the vehicle and endanger the life safety of the driver. [0003] In order to solve the above problems, we propose a magnetic safety guardrail. Contents of the invention [0004] The purpose of the present invention is to solve the problems in the background technology, and propose a magnetic attraction type safety guardrail. [0005] In order to achieve the above object, the present invention adopts the following technical solution: a magnetic type safety guardrail,...
