Anti-collision road barricade based on non-Newtonian fluid

Abstract

The invention relates to the technical field of barricades, and discloses an anti-collision road barricade based on a non-Newtonian fluid. The anti-collision road barricade comprises a base; positionresetting mechanisms are arranged on four corners of the top of the base; a mounting plate is arranged at the tops of the four position resetting mechanisms; a bearing is inlaid in the middle of the mounting plate; a supporting column is fixedly mounted on the inner ring of the bearing; a protecting ring is fixedly mounted at the top of the supporting column; and a cavity inside the protecting ring is filled with the non-Newtonian fluid. According to the anti-collision road barricade, when the protecting ring is collided, the viscosity of the non-Newtonian fluid can be increased substantiallyat the moment of stress, the non-Newtonian fluid can be changed into a hard solid instantaneously, the anti-collision performance of the barricade is guaranteed, and damage caused by the collision force to the barricade is prevented; meanwhile, the barricade can be restored by the aid of the position resetting mechanisms after collision, so that inconvenience can be prevented from being brought tomaintenance persons, and dangers to vehicles can be reduced; and the non-Newtonian fluid has the advantages of convenience in use and low cost.

Description

technical field [0001] The invention relates to the technical field of road barriers, in particular to an anti-collision road barrier based on non-Newtonian fluid. Background technique [0002] On urban roads, in order to prevent vehicles from driving from the motorway to the sidewalk to injure pedestrians or non-motorized vehicles, roadblocks are often set up between the motorway and the sidewalk as a barrier. The current road barriers are mostly cement column structures or hollow structures. Iron column structure, but the anti-collision performance of the roadblock is not good. After the driving vehicle hits the roadblock, the roadblock will be deformed or damaged, causing difficulties for maintenance personnel or causing danger to the vehicle itself. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides an anti-collision road barrier based on non-Newtonian fluid, which has t...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an anti-collision road barrier based on non-Newtonian fluid, which has the advantages of low cost, good anti-collision performance and reset after collision, and solves the problem of poor anti-collision performance of the road barrier and the problem of driving After the vehicle hits the roadblock, it will cause the roadblock to deform, causing difficulties for the construction workers or causing danger to the vehicle itself.
