Problems solved by technology

However, most of the non-Newtonian fluid speed bumps currently used are integral structure speed bumps. The non-Newtonian fluid is sealed in a separate air bag, and the vehicle is under great pressure when passing by. Once the air bag ruptures, a large amount of non-Newtonian fluid will leak out. Newtonian fluid is not only inconvenient for cleaning and maintenance, but also causes waste of resources

Abstract

The invention discloses a non-Newtonian fluid flexible speed bump which comprises bow-shaped supports, bag strips and an arc-shaped cover. The bow-shaped supports are provided with through holes. Thetwo bow-shaped supports are symmetrically and vertically connected to the ground. The bag strips are strip-shaped hollow sealed air bags made of a plastic material and contain a non-Newtonian fluid material inside. The multiple bag strips are erected on the two bow-shaped supports through the through holes. The two ends of each bag strip extend out of the bow-shaped supports. The two ends of the arc-shaped cover are connected with the top faces of the two bow-shaped supports through screws. The non-Newtonian fluid flexible speed bump has the beneficial effects of being good in shock absorptioneffect, high in interchangeability, capable of conveniently replacing the bag strips, low in maintenance cost, capable of saving energy and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of traffic facilities, in particular to a non-Newtonian fluid flexible speed bump. Background technique [0002] The speed bump is a kind of traffic safety facility. It is a barrier with slopes on both sides and slightly higher than the road surface. It is usually set on roads prone to traffic accidents or roads that require vehicles to slow down. It can also be installed in schools, residential areas and The entrance of industrial and mining enterprises. [0003] Non-Newtonian fluids refer to fluids that do not satisfy Newton's experimental law of viscosity, that is, fluids that have a non-linear relationship between shear stress and shear strain rate. Concentrated solutions and suspensions of polymers are generally non-Newtonian fluids. Polyethylene, polyvinyl chloride, nylon, polyester, various engineering plastics, melts and solutions of chemical fibers, etc., are all non-Newtonian fluids. Oil, mud, p...
