Intelligent anti-collision guardrail structure

Abstract

The invention relates to an intelligent anti-collision guardrail structure. The intelligent anti-collision guardrail structure consists of a power system, an anti-collision system, a car preventing system, a violation and evidence obtaining system, an intelligent system, an alarming and reminding display system and a control system. The power system consists of a solar cell panel, a storage battery, a motor, a speed changing box, a hydraulic motor and a hydraulic pump. The anti-collision system consists of a lifting subsystem, a flexible protection subsystem, a semi-rigidity protection subsystem, a rigidity protection subsystem, an air cushion protection subsystem and a magnetic protection subsystem. The violation and evidence obtaining system consists of a camera, a video camera, a radar tachymeter, a wifi device, a GPS device and a data rod. The intelligent anti-collision guardrail structure has the advantages of being high in intellectualization, capable of adjusting a collision angle, high in construction speed, convenient to maintain and long in service life.

Description

An intelligent anti-collision guardrail structure technical field The invention belongs to the technical field of anti-collision guardrails, and in particular relates to an intelligent anti-collision guardrail structure. Background technique Anti-collision barriers are an important part of road engineering. At present, there are three types of anti-collision barriers at home and abroad, namely steel guardrails (mainly cement concrete guardrails, New Jersey guardrails), semi-rigid guardrails (main types are column-type corrugated plate Guardrails), flexible guardrails (the main type is rope guardrails), each of the three guardrails has its own advantages and disadvantages: (1) Steel guardrails (cement concrete guardrails, New Jersey guardrails), the advantages of steel guardrails are high strength, impact resistance, and The impact effect is good and the service life is long. It is often used for the protection of the outside of the bridge. However, the disadvantages of the...

Anti-collision barriers are an important part of road engineering. At present, there are three types of anti-collision barriers at home and abroad, namely steel guardrails (mainly cement concrete guardrails, New Jersey guardrails), semi-rigid guardrails (main types are column-type corrugated plate Guardrails), flexible guardrails (the main type is rope guardrails), each of the three guardrails has its own advantages and disadvantages: (1) Steel guardrails (cement concrete guardrails, New Jersey guardrails), the advantages of steel guardrails are high strength, impact resistance, and The impact effect is good and the service life is long. It is often used for the protection of the outside of the bridge. However, the disadvantages of the steel guardrail are also obvious, that is, the steel guardrail has no deformation and cannot absorb energy. The damage to the vehicle is too serious, and the lives and property losses of the drivers and passengers are too great; (2) semi-rigid guardrail (column-type corrugated plate guardrail), the advantage of the semi-rigid guardrail is that it has a certain strength, and the guardrail is deformed when it is impacted. It can absorb energy, and the loss of vehicle damage is small, and it has a protective effect on cars and low-speed trucks

The disadvantage of the semi-rigid guardrail is that it has almost no protective ability for freight vehicles with high speeds. In addition, the semi-rigid guardrail is easily damaged and needs to be replaced and repaired frequently. (3) The advantage of the flexible guardrail (rope guardrail) is that when it is impacted The guardrail has large deformation, good energy absorption, and small vehicle loss. The disadvantage of the flexible guardrail is that it has poor strength, weak protection ability, and is easy to be damaged. It needs to be replaced and repaired frequently; the flexible guardrail is only suitable for roads with medium and low traffic and mainly cars , the applicable surface is too small
