Description

Technical Field

[0001] The utility model relates to the technical field of anti-glare equipment for bridges, in particular to an anti-glare structure for bridge corrugated guardrails. Background Art

[0002] In the scenario of night traffic on bridges, glare generated by headlights of oncoming vehicles will seriously interfere with drivers' visual judgment, causing problems such as temporary vision decline and blurred vision for drivers, which greatly increases the risk of traffic accidents such as rear-end collisions and scratches. At present, the anti-glare facilities matched with bridge corrugated guardrails are mainly divided into two categories: one is independent anti-glare panels, which are usually made of PVC, fiberglass and other materials into rectangular or trapezoidal panels, fixed on the top of guardrail posts through brackets, and block oncoming light by the panels; the other is anti-glare nets, which are mostly diamond or square grid structures welded by low-carbon steel wires, connected to guardrails through metal frames, and weaken glare relying on the light-shielding effect of grids. In addition, some bridges have also tried to attach reflective films to the corrugated panels of guardrails to remind drivers by reflecting light, but this method cannot fundamentally solve the glare problem and can only play an auxiliary warning role.

[0003] The existing anti-glare facilities have obvious deficiencies in practical application: first, the anti-glare effect is limited. Due to the fixed spacing of independent anti-glare panels, when a vehicle drives to the gap between the panels, the phenomenon of "glare leakage" is prone to occur, and the angle of the panels cannot be adjusted according to the light irradiation angle, so the anti-glare effect is greatly reduced in special road sections such as curves and ramps; anti-glare nets have weak shielding ability for strong light due to large grid gaps, and are only suitable for low light intensity scenarios. Therefore, we propose an anti-glare structure for bridge corrugated guardrails to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-glare structure for bridge corrugated guardrails, so as to solve the problems raised in the above background art that the existing anti-glare facilities in the current market are prone to "glare leakage", the angle of the panel cannot be adjusted according to the light irradiation angle, and the anti-glare effect is greatly reduced in special road sections such as curves and ramps.

[0005] In order to achieve the above purpose, the utility model provides the following technical solution: an anti-glare structure for bridge corrugated guardrails, comprising an anti-glare panel body, an elastic connecting member, an angle adjusting component and a fixing base, wherein the lower end face of the fixing base is fixed with the bridge corrugated guardrail through bolts, the anti-glare panel body is connected with the elastic connecting member through the angle adjusting component, the lower end face of the elastic connecting member is fixed with the fixing base through high-strength galvanized bolts, one side of the anti-glare panel body is provided with a groove, and the other side of the anti-glare panel body is provided with reinforcing ribs.

[0006] Preferably, the anti-glare panel has a height of 65cm-75cm, a width of 25cm-35cm, and a thickness of 6mm-10mm, and is made of a composite material of modified polypropylene and glass fiber.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-6 The present invention provides the following technical solution: a bridge corrugated guardrail anti-glare structure, including an anti-glare plate 1, an elastic connector 4, an angle adjustment component and a fixed base 10. The lower end face of the fixed base 10 is fixed to the bridge corrugated guardrail by bolts 7. The anti-glare plate 1 is connected to the elastic connector 4 by the angle adjustment component. The lower end face of the elastic connector 4 is fixed to the fixed base 10 by high-strength galvanized bolts 7. A groove 2 is provided on one side of the anti-glare plate 1, and a reinforcing rib 3 is installed on the other side of the anti-glare plate 1. Furthermore, the anti-glare panel 1 has a height of 65cm-75cm, a width of 25cm-35cm, and a thickness of 6mm-10mm. The anti-glare panel 1 is made of modified polypropylene and glass fiber composite material, which improves its anti-glare effect and extends its service life. Furthermore, the groove 2 has an arc-shaped structure, with a depth of 4mm-6mm and a spacing of 6cm-10cm. There are three parallel grooves 2 on the anti-glare panel 1. The inner wall of the groove 2 is coated with a nano anti-reflective coating, which is made of silicon dioxide nanoparticles. The strong light is dispersed by the diffuse reflection of the arc-shaped groove 2, and the anti-reflective coating absorbs some of the light, further improving its anti-glare effect. Furthermore, the reinforcing ribs 3 are distributed in a "+" shape, with a width of 8mm-12mm and a thickness of 4mm-6mm, which improves the rigidity of the anti-glare panel 1 and enhances the panel's wind load resistance. Furthermore, the angle adjustment component includes a rotating rod 5, a mounting rod 6, and a fixing plate 8. The upper end of the mounting rod 6 is connected to the reinforcing rib 3 by a high-strength galvanized bolt 7, and the lower end of the mounting rod 6 is connected to the upper end of the elastic connector 4 by the rotating rod 5. The side of the upper end of the elastic connector 4 is connected to the fixing plate 8. The fixing plate 8 has mounting holes 9 distributed at equal angles with respect to the axis of the rotating rod 5. The fixing plate 8 and the mounting rod 6 are fixed together by a high-strength galvanized bolt 7. The angle of the plate can be flexibly adjusted according to the slope of the bridge section, the curvature of the curve, and the angle of seasonal sunlight to ensure the best anti-glare effect. Furthermore, the elastic connector 4 is a "U"-shaped structure made of EPDM rubber, which can buffer the impact of vehicle collisions or strong winds on the anti-glare component and prevent the component from breaking. Specifically, when using the anti-glare structure of the bridge corrugated guardrail, the light emitted from the headlights of oncoming vehicles propagates in a divergent manner, with the propagation angle of the core strong light area typically being 15°-25°. The height of the anti-glare panel 1 is designed to be 70cm. The anti-glare panel 1 is installed by fixing the lower end of the fixing base 10 to the bridge corrugated guardrail with bolts 7. After installation, the top of the anti-glare panel 1 is approximately 80cm-100cm above the bridge surface, precisely covering the core area of ​​the driver's field of vision. When light propagates to the anti-glare panel 1, it first physically intercepts the light in the core strong light area, preventing it from directly entering the driver's field of vision. The arc-shaped groove 2 on the anti-glare panel 1 provides secondary shielding of light at the gaps. Even if light passes through the gap between two panels, it will be blocked by the sidewalls of the arc-shaped groove 2 of the adjacent panels, forming a double shielding effect. Simultaneously, the spacing between the anti-glare panels 1 is set at 2.5m, combined with the arc-shaped groove 2... The lateral extension characteristics of the anti-glare plate 1 make the anti-glare range of adjacent anti-glare plates overlap in the horizontal direction, completely eliminating the glare hazards at the gaps and forming a continuous and uninterrupted anti-glare barrier. The silica nanoparticle coating sprayed on the inner wall of the arc-shaped groove 2 has a particle diameter of about 50nm-100nm, which forms a specific proportional relationship with the wavelength of visible light. When light shines on the surface of the coating, the nanoparticles will absorb some of the light into the particle through the photon capture effect. Through the scattering and energy conversion inside the particle, the light energy is converted into weak heat energy and released, thereby reducing the intensity of reflected light. The curved surface structure of the arc-shaped groove 2 causes the unabsorbed light to undergo diffuse reflection. After the light shines on the curved surface of the groove 2, it will be dispersed at multiple angles along the tangent direction of the curved surface, rather than reflected along the original direction. Among them, the upward scattered light will be absorbed by the air above the bridge or the night environment, and the downward scattered light will shine on the bridge surface. Only a very small amount of light will reach the driver's field of vision, and the intensity has been greatly reduced. On straight roads, oncoming vehicle headlights illuminate horizontally at night. On sloping roads, the angle of light illumination increases. In winter, due to the lower solar altitude angle, the angle of sunlight illumination during the day also decreases. By driving the anti-glare plate 1, the mounting rod 6 rotates on the elastic connector 4 via the rotating rod 5. The tilt angle of the anti-glare plate 1 is adjusted according to different scenarios. After the angle is adjusted, the bolt 7 is threaded through the corresponding mounting hole 9 and connected to the mounting rod 6 to lock the mounting rod 6, thereby locking the angle of the anti-glare plate 1. On sloping roads, the plate is tilted 10°-15° towards the light source to increase the area of ​​light blocking. In winter, during the day, it is tilted 5°-8° to prevent sunlight from directly shining into the driver's eyes, ensuring optimal anti-glare performance in different scenarios.
