An anti-collision road barrier based on non-Newtonian fluid

Abstract

The invention relates to the technical field of roadblocks, and discloses a non-Newtonian fluid-based anti-collision road barrier, including a base, and position reset mechanisms are arranged at the four corners of the top of the base, and the tops of the four position reset mechanisms are arranged There is a mounting plate, the middle part of the mounting plate is inlaid with a bearing, the inner ring of the bearing is fixedly installed with a support column, the top of the support column is fixedly installed with a protection ring, and the cavity inside the protection ring is filled with non- Newtonian fluid. In the present invention, when the protection ring is hit, the viscosity of the non-Newtonian fluid will be greatly increased at the moment of force, so that the non-Newtonian fluid will instantly become a hard solid, which ensures the anti-collision performance of the roadblock and prevents the impact force from causing damage. The roadblock is damaged, and at the same time, the position reset mechanism will restore the roadblock after the collision, avoiding inconvenience to the maintenance personnel and reducing the danger to the vehicle itself, and the non-Newtonian fluid has the advantages of convenient 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.
