[0002] A tunnel refers to an engineering building buried in the ground, which is a form of human use of underground space. The structure of a tunnel consists of two parts: the main building and ancillary equipment. The main building consists of a tunnel body and a tunnel door. The ancillary equipment includes a car shelter, fire-fighting facilities, emergency communications and drainage facilities. Long tunnels also have special ventilation and lighting equipment. In order to facilitate driving, multiple tunnel warning devices are generally installed on the inside of the tunnel. They are important basic safety equipment. Most of them are fixed on the side walls of the tunnel, using reflective strips or boards, warning lights or signs to guide and warn vehicles. Sometimes when a vehicle is too close to the warning sign on the side wall of the tunnel, it will collide with and damage the warning sign on the side wall of the tunnel.

[0022] Figure 1 A tunnel safety warning device of the utility model is shown, comprising a fixed mounting base assembly, a tunnel safety warning assembly rotatably arranged on the fixed mounting base, a spring assembly 3 is arranged between the fixed mounting base assembly and both sides of the tunnel safety warning assembly, the tunnel safety warning assembly comprises a fixed block 6 rotatably connected to the fixed mounting base assembly, and a safety warning sign 5 separately arranged from the fixed block 6;

[0023] Among them, the lower surface of the safety warning sign 5 is symmetrically provided with connecting ears 7, the fixing block 6 is located between the connecting ears 7, and the joint surface of the fixing block 6 and the connecting ears 7 is provided with multiple positioning holes, and the connecting ears are locked in the positioning holes by a fixing mechanism.

[0024] Working principle:

[0025] First, the fixed mounting base assembly is firmly installed in a suitable position in the tunnel. This base assembly not only provides a stable support, but also allows the tunnel safety warning assembly to rotate thereon through its structural design.

[0026] The core parts of the tunnel safety warning assembly are the fixed block 6 and the safety warning sign 5. The fixed block 6 is connected to the fixed mounting base assembly by rotation, so that the warning assembly can rotate when subjected to external force, but then can be restored to its original position through the spring assembly 3.

[0027] The safety warning sign 5 and the fixing block 6 are separately arranged, which makes it easier to replace the warning sign. The lower surface of the safety warning sign 5 is symmetrically provided with connecting ears 7, and the fixing block 6 is located between the connecting ears 7. A positioning hole is provided on the joint surface of the fixing block 6 and the connecting ears 7. The symmetrically arranged connecting ears 7 can pass through the positioning hole and be locked on the fixing block by a fixing mechanism 9 (such as a bolt or a locking device), thereby ensuring a stable connection between the fixing block 6 and the safety warning sign 5.

[0028] When the warning sign is damaged by impact, it is only necessary to loosen the fixing mechanism 9, remove the damaged warning sign from the fixing block 6, and replace it with a new one, thereby improving the maintenance efficiency and reducing the maintenance cost.

[0029] In the above scheme, anti-collision protrusions 8 are arranged around the two sides of the safety warning sign 5; wherein, the anti-collision protrusions 8 are connected to the safety warning sign 5 by bonding. The anti-collision protrusions 8 are connected to the safety warning sign 5 by bonding. This technical scheme is adopted, and this connection method is both simple and effective. It ensures that the anti-collision protrusions 8 can be firmly attached to the warning sign and are not easy to fall off. At the same time, the bonding connection also has a certain buffering effect, which can absorb the impact force to a certain extent, and further protect the warning sign from damage.

[0030] When a vehicle or other object in the tunnel accidentally hits the safety warning sign 5, the anti-collision protrusion 8 will first contact the impact object and bear most of the impact force. Due to the presence of the anti-collision protrusion 8, the impact force is dispersed and absorbed, reducing the impact force directly acting on the warning sign itself. This can not only prevent the warning sign from being broken or deformed due to the impact, but also ensure that the safety information on the warning sign is still clearly visible after the impact, and continue to play its warning role.

[0031] In the above solution, the anti-collision protrusion 8 is made of rubber or foamed plastic. With this technical solution, the rubber has good elasticity and impact resistance, can absorb and disperse the impact force, and effectively protect the safety warning sign 5 from damage. At the same time, the rubber also has certain wear resistance and weather resistance, which can ensure that the anti-collision protrusion 8 maintains good performance during long-term use.

[0032] Foamed plastics are known for their light weight and cushioning properties. They are filled with tiny bubbles that compress and absorb energy when hit, reducing the impact on the warning sign. In addition, foamed plastics have excellent processing properties and can be easily made into various shapes and sizes to meet the design requirements of different warning signs.

[0033] Therefore, whether rubber or foamed plastic is used as the material of the anti-collision protrusion 8, the anti-collision ability of the safety warning sign 5 can be effectively enhanced, and the durability and reliability of the tunnel safety warning device can be improved.

[0034] In the above scheme, the fixed installation base assembly includes a fixed plate 1, and arc-shaped guide slide bars 2 are fixedly arranged on both sides of the fixed plate 1, and fixing holes 4 are opened at both ends of the fixed plate 1. The fixed plate 1 is installed on the side wall of the tunnel through bolts and the fixing holes 4;

[0035] Among them, each arc-shaped guide slide bar 2 passes through the waist-shaped hole opened on the fixed block 6, and the spring assembly 3 is sleeved on the arc-shaped guide slide bar 2. With this technical solution, the core of the anti-collision fixed base assembly is the fixed plate 1, which serves as the basis of the entire early warning device and is responsible for firmly fixing the device on the side wall of the tunnel. Arc-shaped guide slide bars 2 are fixedly arranged on both sides of the fixed plate 1. These slide bars not only provide stable support, but also provide guidance for the rotation of the tunnel safety early warning assembly. When the early warning assembly is hit by an external force and rotates, the arc-shaped guide slide bar 2 can ensure that it moves along a predetermined trajectory, avoiding unnecessary deviation or damage.

[0036] In addition, fixing holes 4 are provided at both ends of the fixing plate 1, so that the fixing plate 1 can be conveniently installed on the side wall of the tunnel through bolts and the fixing holes 4. This installation method is simple and firm, and can ensure the stability of the early warning device in the tunnel.

[0037] The spring assembly 3 is an important component of the early warning device, which is sleeved on the arc-shaped guide slide bar 2. When the early warning assembly is hit and rotates, the spring assembly 3 will be compressed and absorb the impact force. Subsequently, the spring assembly 3 will use its elastic restoring force to cause the early warning assembly to automatically return to its original position. This design not only improves the anti-impact ability of the early warning device, but also ensures that it can quickly return to working state after being hit.

[0038] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
