Safe driving warning device for guardrails of highways, bridges or tunnels

Abstract

The invention discloses a safe driving warning device for guardrails of roads, bridges or tunnels. A group of guardrails are arranged on both sides of the road, bridge or tunnel along the forward direction of vehicles, and a set of fixed blocks are arranged side by side along the length direction of each guardrail. ; There is a hoop on the two fixing blocks at the end of each guardrail, and a white transparent hose is passed between the inner holes of all the installation sleeves. The white transparent hose is matched with the installation sleeve, white and transparent Inside the hose is a warning glass microshell. The present invention abandons structures such as reflective cursors on the guardrail in the traditional structure, and replaces it with a white transparent hose through the gap of the installation sleeve to warn that the hollow microshell of the glass microshell is equipped with fluorescent powder with a powder structure; the white transparent hose After being blown by the wind, it will rotate or shake with the wind, which will cause the warning glass micro-shell to sway along with the white transparent hose, and can be used in general roads, expressways, bridges and tunnels.

Description

technical field [0001] The invention belongs to the traffic field, in particular to a safety driving warning device for road, bridge or tunnel guardrails. Background technique [0002] With the development of society, traffic is becoming more and more important. However, driving safety is an issue that has to be taken seriously. Every year, traffic accidents across the country lead to a large number of casualties and property losses. At the same time, due to the poor visibility at night, the probability of safety accidents at night is significantly higher than that during the day, and traffic accidents are more likely to occur at night on rainy days. In order to avoid traffic accidents at night, warning lights are generally installed on both sides of roads (especially expressways), bridges or tunnels, and these warning lights achieve a prompting effect by actively emitting light. However, the warning lights need to consume electricity, not only need to set up power supply l...

AI Technical Summary

Problems solved by technology

The advantage of this method is that it does not require power consumption, low use and maintenance costs, the emitted light is visible light, and the cost is lower than that of warning lights, but because of the wear-resistant layer, the cost is higher than that of plastic tape and reflective markers; the disadvantage is that the wear-resistant layer After being exposed to wind and sun, the wear-resistant layer will age and fall off, which will expose the phosphor coating, and the surface roughness of the phosphor coating is relatively large. After encountering dust deposition, it is easy to greatly affect the light absorption of the phosphor coating. Energy and luminous efficiency; moreover, the phosphor coating will not occur after contact with water or liquid, so it will be completely ineffective

In addition, even if the wear-resistant layer is not worn, the existing phosphor coating is fixedly coated on the guardrail, and only the phosphor on the surface can effectively absorb light energy. Therefore, in order to avoid wasting materials, the phosphor coating can only be compared Thin, and whether it can glow all night is also a big problem; moreover, the visible light emitted by the fixed phosphor coating is also fixed, and the warning effect of showing width is relatively limited. If the visible light emitted is moving, the warning The effect will be better, and it is less likely to cause visual fatigue, and the existing fixed phosphor coating cannot be achieved at all
