Description

Technical Field

[0001] This utility model relates to the field of highway equipment technology, specifically to an attached anti-glare device. Background Technology

[0002] Anti-glare systems are a crucial component of highway traffic infrastructure, ensuring driving safety. Primarily installed on the central median, they address the glare from oncoming headlights, thereby improving driver comfort and safety. Currently, anti-glare systems come in various forms, including anti-glare panels, anti-glare netting, and tree planting. These systems are typically installed in conjunction with guardrails, a method that offers several advantages. Firstly, using guardrails as a support structure significantly reduces investment costs. Secondly, guardrails also protect the anti-glare systems, extending their lifespan.

[0003] However, traditional anti-glare facilities and their installation techniques for highway median strips still have some shortcomings. For example, the installation of some anti-glare facilities requires pre-installed concrete bases and embedded posts, which not only increases construction difficulty and cost but also requires simultaneous installation with guardrail posts, easily leading to overlapping construction and thus affecting the construction progress. In addition, some anti-glare facilities may not be installed securely enough, or the connection with the guardrail posts may not be tight enough, making them susceptible to loosening or damage from external environmental factors.

[0004] In view of the shortcomings of the above-mentioned traditional anti-glare facilities and their installation technologies, this utility model proposes an attached anti-glare facility. Utility Model Content

[0005] To address the aforementioned issues, this invention provides an attached anti-glare device that eliminates the need for pre-installed concrete bases and embedded columns during construction, significantly reducing construction difficulty and costs, and avoiding disruptions to progress caused by overlapping construction activities.

[0006] The technical solution of this utility model is as follows:

[0009] One end of the connecting plate is fixed to the lower support by welding or bolts, and the other end is fixed to the guardrail post by bolts.

[0010] The connecting plate and the guardrail post are provided with matching through holes. After the bolts pass through the through holes on the connecting plate and the guardrail post, they are tightened with nuts to fix the connecting plate and the guardrail post in place.

[0011] The clamp is a hoop-shaped structure that matches the shape of the guardrail post. One end of the clamp is fixedly connected to the lower support, and the other end has an opening. The clamp is secured to the guardrail post by bolts and nuts.

[0012] The upper column is fixedly connected to the lower support by bolts.

[0013] The two ends of the anti-glare louver unit are fixedly connected to the upper column by bolts.

[0014] A rubber pad is provided on the inside of the clamp.

[0015] The rubber pad is glued to the inside of the clamp.

[0027] like Figure 1 and Figure 2 As shown, the attached anti-glare device mainly includes anti-glare louver unit 5, attached mounting bracket and related connecting parts.

[0028] The attached anti-glare device is attached to the inside of the guardrail post 1 that has been fixedly installed on the road surface 6, and a guardrail plate 8 is installed on the outside of the guardrail post 1.

[0029] The anti-glare louver unit 5 is fixedly installed on the guardrail post 1 using an attached mounting bracket.

[0030] The attached mounting bracket consists of a lower support 3 and an upper column 4. The lower support 3 is fixedly connected to the guardrail column 1, and the upper column 4 is fixedly installed on the top of the lower support 3. The two ends of the anti-glare louver unit 5 are fixedly connected to the upper columns 4 on the two attached mounting brackets respectively.

[0031] The anti-glare louver unit 5 is existing technology and can use commonly available anti-glare louvers. Its main function is to block the glare from oncoming vehicle lights and provide the driver with a clear view.

[0032] In actual production, the louvers of the anti-glare louver unit 5 are usually made of high-strength, weather-resistant plastic or metal materials. Plastic materials have the advantages of being lightweight, low-cost, and corrosion-resistant, making them suitable for highways under general environmental conditions; metal materials, on the other hand, have higher strength and durability, making them suitable for road sections with harsher environments or higher requirements for anti-glare performance.

[0033] Louvered blades are generally flat or curved. Flat louvers have a simple structure and are easy to manufacture and install; curved louvers can better guide light and reduce glare reflection. The angle of the louvers is usually adjusted according to the actual road conditions and design requirements, generally between 30° and 60°, to ensure that they effectively block glare without excessively obstructing the driver's view. The spacing between the louvers also needs to be designed reasonably. Too small a spacing will increase production costs and device weight, while too large a spacing may affect the anti-glare effect.

[0034] The anti-glare louver unit 5 has connection holes at both ends for fixed connection with the upper column 4. The position and size of the connection holes match the connection parts on the upper column 4 to ensure the firmness and stability of the connection.

[0035] The attached mounting bracket is a key component connecting the anti-glare louver unit 5 and the guardrail post 1. It consists of a lower support 3 and an upper post 4.

[0036] The main function of the lower support 3 is to provide stable support for the upper post 4 and to firmly fix the entire device to the guardrail post 1. The lower support 3 is generally long strip or frame-shaped, and its size and structure are designed according to the shape and size of the guardrail post 1 to ensure that it can fit tightly to the guardrail post 1.

[0037] The upper and lower parts of the lower support 3 are fixedly connected to the guardrail post 1 by connecting plate 7 or clamp 2 respectively; this design of multiple connection methods allows the lower support 3 to adapt to guardrail posts 1 of different shapes and sizes, improving the versatility and adaptability of the device.

[0038] When using connecting plate 7 for connection, one end of connecting plate 7 is fixed to the lower support 3 by welding or bolting. Welding provides a strong connection but is not removable; bolting facilitates installation and disassembly, as well as later maintenance and replacement. The other end of connecting plate 7 is fixed to the guardrail post 1 by bolts. Connecting plate 7 and guardrail post 1 have matching through holes. Bolts pass through these through holes and are tightened with nuts, thus achieving a fixed connection between connecting plate 7 and guardrail post 1. In actual operation, it is necessary to ensure the accurate positioning of the through holes and that the specifications and materials of the bolts meet the requirements to guarantee the strength and stability of the connection.

[0039] When using clamp 2 for connection, clamp 2 is a hoop-shaped structure that matches the shape of guardrail post 1; one end of clamp 2 is fixedly connected to the lower support 3, which can be done by welding or bolting; the other end of clamp 2 has an opening, which is secured with bolts and nuts, so that clamp 2 can be clamped onto guardrail post 1; in order to increase the friction between clamp 2 and guardrail post 1 and prevent clamp 2 from loosening, a rubber pad is provided on the inside of clamp 2; the rubber pad is glued to the inside of clamp 2, and the material of the rubber pad should have good elasticity and wear resistance to ensure that it can function effectively for a long time.

[0040] In addition, shock-absorbing pads made of rubber or silicone are installed at the connection between the lower support 3 and the guardrail post 1. The function of the shock-absorbing pads is to reduce the impact of vibration generated during vehicle operation on the device, prevent the device from loosening or being damaged due to vibration, and also reduce noise. The size and thickness of the shock-absorbing pads should be selected according to the actual situation to ensure that they can effectively play a shock-absorbing role.

[0041] The main function of the upper column 4 is to support the anti-glare louver unit 5 and fix it to the lower support 3. The upper column 4 is generally cylindrical or square in shape, and its size and strength are designed according to the weight and stress of the anti-glare louver unit 5.

[0042] The upper column 4 is fixedly connected to the lower support 3 by bolts; the upper column 4 and the lower support 3 are provided with matching connecting holes, and the bolts are tightened with nuts after passing through the connecting holes to achieve a fixed connection between the upper column 4 and the lower support 3.

[0043] The top of the upper column 4 is provided with a connecting part for fixed connection with the anti-glare louver unit 5; the shape and size of the connecting part match the connecting holes at both ends of the anti-glare louver unit 5 to ensure the firmness and stability of the connection; in the actual installation process, it is necessary to ensure that the two ends of the anti-glare louver unit 5 are aligned with the connecting part of the upper column 4, and then fix them together with bolts.

[0044] The guardrail post 1 is the installation base of this utility model device, and it has been fixedly installed on the road surface 6. The shape and size of the guardrail post 1 are selected according to the road design requirements and relevant standards. Common shapes include round and square. The guardrail post 1 is generally made of steel, which has high strength and durability and can withstand external forces such as vehicle collisions.

[0045] The guardrail panel 8 is installed on the outside of the guardrail post 1. Its main function is to prevent vehicles from running off the road and ensure driving safety. The guardrail panel 8 is generally wavy or flat, and its material is mostly steel. The guardrail panel 8 and the guardrail post 1 are fixedly connected by bolts or other connectors. The connection method should be firm and reliable to ensure that it can effectively function in the event of a vehicle collision.

[0046] The installation process for this attached anti-glare device is as follows:

[0047] (a) Preparatory work
