Problems solved by technology

[0002] When a vehicle enters a tunnel at a relatively high speed (about 80 km / h) during the day, due to the large difference in light inside and outside the tunnel entrance, the driver's vision will be obstructed within 3 to 5 seconds of entering the tunnel entrance. , the driver’s eyes will be dark, and the objects in the tunnel cannot be seen clearly. In this case, the vehicle is prone to rear-end collisions and other traffic accidents.
In order to solve the visual obstacles caused by the sudden change of light inside and outside the tunnel entrance, the patented technical solution with the patent application number 2009200333562.0 provides a multi-functional visual buffering and racking system at the entrance and exit of the highway tunnel. Although this system can solve the above problems to a certain extent, but Its structure is complex, involving structural parts such as motors, LEDs, solar cells, photoelectric sensors, etc., and installation and maintenance are troublesome. If a part of the system is damaged, the entire system will be paralyzed

Embodiment approach

[0011] The highway tunnel light buffering device is an arched scaffolding body 1 with a length of 60 m. The scaffolding body 1 is evenly divided into front, middle and rear sections in the length direction. The light transmission holes 2 are evenly opened, the total area of ​​the light transmission holes 2 on the front section of the scaffold body 1 is greater than the total area of ​​the light transmission holes 2 on the middle section of the scaffold body 1, and the total area of ​​the light transmission holes 2 on the middle section of the scaffold body 1 The total area is greater than the total area of ​​the light-transmitting holes 2 on the rear section of the scaffold body 1, so that the total area of ​​the light-transmitting holes 2 on each section of the scaffold body 1 decreases gradually from the front section to the rear section of the scaffold body 1. An atomized glass 3 is installed on the frame body 1 with bolts to cover the light-transmitting hole 2 , and a seali...

Embodiment approach 2

[0013] The road tunnel light buffering device is an arched scaffold body 1, the length of which is 110m, and the scaffold body 1 is evenly divided into three sections: front, middle and rear in the length direction, and each section of scaffold body 1 The light transmission holes 2 are evenly opened, the total area of ​​the light transmission holes 2 on the front section of the scaffold body 1 is greater than the total area of ​​the light transmission holes 2 on the middle section of the scaffold body 1, and the total area of ​​the light transmission holes 2 on the middle section of the scaffold body 1 The total area is greater than the total area of ​​the light-transmitting holes 2 on the rear section of the scaffold body 1, so that the total area of ​​the light-transmitting holes 2 on each section of the scaffold body 1 decreases gradually from the front section to the rear section of the scaffold body 1. An atomized glass 3 is installed on the frame body 1 with bolts to cove...

Embodiment approach 3

[0015] The highway tunnel light buffering device is an arched scaffolding body 1, the length of which is 85m. The light transmission holes 2 are evenly opened, the total area of ​​the light transmission holes 2 on the front section of the scaffold body 1 is greater than the total area of ​​the light transmission holes 2 on the middle section of the scaffold body 1, and the total area of ​​the light transmission holes 2 on the middle section of the scaffold body 1 The total area is greater than the total area of ​​the light-transmitting holes 2 on the rear section of the scaffold body 1, so that the total area of ​​the light-transmitting holes 2 on each section of the scaffold body 1 decreases gradually from the front section to the rear section of the scaffold body 1. An atomized glass 3 is installed on the frame body 1 with bolts to cover the light-transmitting hole 2 , and a sealing ring 4 is arranged between the atomized glass 3 and the frame body 1 .

Abstract

The invention relates to a highway tunnel light buffer device which is an arched shed frame body. The length of the highway tunnel light buffer device is 60-110 m. Light holes are formed in the shed frame body. According to the device, when a vehicle enters a tunnel at a high speed in the daytime, the visual disturbance of a driver due to the light difference inside a tunnel entrance and outside the tunnel entrance can be avoided.

Description

technical field [0001] The invention relates to a device installed in front of a road tunnel entrance for buffering the visual disturbance caused by sudden light changes to vehicle drivers. Background technique [0002] When a vehicle enters a tunnel at a relatively high speed (about 80 km / h) during the day, due to the large difference in light inside and outside the tunnel entrance, the driver's vision will be obstructed within 3 to 5 seconds of entering the tunnel entrance. , the driver’s eyes will be dark, and the objects in the tunnel cannot be seen clearly. In this case, the vehicle is prone to rear-end collisions and other traffic accidents. In order to solve the visual obstacles caused by the sudden change of light inside and outside the tunnel entrance, the patented technical solution with the patent application number 2009200333562.0 provides a multi-functional visual buffering and racking system at the entrance and exit of the highway tunnel. Although this system c...
