Energy-absorbing collision-resistant road guardrail for smart city

Abstract

The invention discloses an energy-absorbing collision-resistant road guardrail for a smart city, and particularly relates to the field of smart cities, the energy-absorbing collision-resistant road guardrail comprises a mounting stand column and a wave-shaped protective guard, the surface of the mounting stand column is fixedly sleeved with a fixed sleeve seat, a supporting connecting seat is fixedly mounted on the inner side of the fixed sleeve seat, and a collision energy-absorbing mechanism is fixedly mounted on the top surface of the supporting connecting seat; deformation connecting lug bases are fixedly installed on the inner sides of the waveform protective fences, top connecting bases are fixedly installed on the inner sides of the deformation connecting lug bases, and the outer sides of the collision energy absorption mechanisms are fixedly sleeved with protective layers. By arranging the deceleration buffer mechanism, redirection of vehicle collision is achieved through rotation of the vehicle accidental collision energy absorption mechanism, kinetic energy of the vehicle is slowly reduced through rotation friction of the collision energy absorption mechanism of the vehicle and the guardrail, and high temperature and sparks are prevented from being generated during friction through the protective layer structure on the outer side; accidents of vehicle fire disasters and explosion are eradicated, and the safety performance of the protective fence is improved.

Description

technical field [0001] The invention relates to the technical field of smart cities, and more specifically, the invention is an energy-absorbing impact-resistant road guardrail for smart cities. Background technique [0002] In the context of the era of the Internet of Everything, the "new smart city" aims to serve the people all the time, efficient and orderly urban governance, data openness, integration and sharing, green and open-source economic development, and safe and clear cyberspace. , information-led, reform and innovation, promote the deep integration and iterative evolution of the new generation of information technology and urban modernization, realize the coordinated development of the country and the city, combine road supervision and the Internet of Things, and realize an intelligent, efficient and safe smart city. [0003] However, the speed of China's road construction has been unable to keep up with the rapid growth of car ownership. The actual traffic load...

Problems solved by technology

[0006] However, the intelligent road guardrails for smart cities with anti-shock functions on the market are not only complex in structure, but also have a single function. In the existing road guardrail technology, it is not convenient to buffer the vehicle after the vehicle hits the road guardrail. It is best to decelerate the vehicle hitting its end with a suitable deceleration rate, so as not to apply a particularly high deceleration to the vehicle, and avoid the guardrail piercing the interior of the vehicle
