Problems solved by technology
[0002] Tunnels are generally opened in the middle of the mountain. Due to the deep depth of the tunnel and the closed exterior, the light in the tunnel is very weak. In order to solve this problem, a large number of lamps are generally installed in the tunnel for lighting, and the disadvantages of lamp lighting It still exists, for example, glare affects the driver's normal driving, and for example, insufficient light still leads to unclear vision. The surrounding environment is dim and the tunnel depth is deep, often driving in the tunnel for a long time, the driver will feel sleepy, eyesight Fatigue will also occur, and because the two sides of the tunnel are walls, the avoidance space is limited. Once a car accident or fatigue driving occurs, it is easy to hit the side walls and cause serious traffic accidents.

Embodiment Construction
[0020] Such as figure 1 As shown, the tunnel protection unit includes more than one set of protection devices equidistantly arranged on both sides of the tunnel, and adjacent protection devices are in contact with each other and arranged to extend toward the length of the tunnel;
[0021] Such as image 3 As shown, each protective device includes a protective bracket 1, the distance of the protective bracket must be set sufficiently, such as 100 meters or 200 meters, set according to needs, the bottom sides of the protective bracket 1 are respectively rotated and installed on the tunnel ground In the rotation groove 4 that offers, there is a protective cavity 22 in the middle of the protective bracket 1, and more than one protective rod 26 is arranged side by side in the protective cavity 22, and a sliding bushing 24 is arranged at the bottom of the protective rod 26, and the middle of the sliding bushing 24 A through hole is provided through each sliding bushing 24, and a sh...

The invention discloses a tunnel protection unit. The tunnel protection unit comprises more than one set of protection device arranged on the two sides of a tunnel at equal distance. The adjacent protection devices are in contact and are arranged in a manner of extending in the length direction of the tunnel. Each protection device comprises a protection support. The two sides of the bottom of each protection support are rotationally mounted in rotating grooves formed in the tunnel ground. A protection cavity is formed in the middle of each protection support. More than one protection rod is arranged in the protection cavity side by side. A sliding shaft sleeve is arranged at the bottom of each protection rod. A through hole is formed in the middle of each sliding shaft sleeve in a penetrating manner. A shaft rod is arranged in each through hole by penetrating through the corresponding sliding shaft sleeve. The two ends of each shaft rod penetrate through the corresponding protection support and are rotationally connected with the corresponding protection support. According to the protection unit, vehicles in the tunnel can be protected, the vehicles can be limited when running tothe extreme positions, the situation that the vehicles continue to get close to side walls to impact on the walls can be avoided, and quite high safety is achieved.
Description
technical field [0001] The invention relates to a tunnel protection unit. Background technique [0002] Tunnels are generally opened in the middle of the mountain. Due to the deep depth of the tunnel and the closed exterior, the light in the tunnel is very weak. In order to solve this problem, a large number of lamps are generally installed in the tunnel for lighting, and the disadvantages of lamp lighting It still exists, for example, glare affects the driver's normal driving, and for example, insufficient light still leads to unclear vision. The surrounding environment is dim and the tunnel depth is deep, often driving in the tunnel for a long time, the driver will feel sleepy, eyesight Fatigue will also occur, and since the two sides of the tunnel are walls, the avoidance space is limited. Once a car accident or fatigue driving occurs, it is easy to hit the side walls and cause serious traffic accidents. Contents of the invention [0003] The technical problem to be so...
