A safety fence for road and bridge

Abstract

The invention discloses a safety guard railing for roads and bridges. The safety guard railing comprises a fixed seat, a fixed plate and a bolt hole. The safety guard railing has the beneficial effects that through the arrangement of a light barrier, a first rotating rod, a second rotating rod and a reflective coating, the device can effectively block the light from vehicles in the opposite direction, it is ensured that the driver can see the road information clearly, and the occurrence of traffic accidents is avoided; through the arrangement of a first lower transverse plate and a second lower transverse plate, a lower rotating shaft, a first upper transverse plate, a second upper transverse plate, an upper rotating shaft, a first fixed pin, a second fixed pin, a vertical plate, a first strong spring and a second strong spring, the car impact is flexibly buffered by the device, severe deformation of car is avoided, and the damage to the personnel in the vehicle is reduced, through thearrangement of a gravity sensor, a controller, a solar panel, a signal transmitter and a warning light, the warning light can be lighted up and give warning and the information of the fallen guard railing is sent to remote monitoring personnel for timely maintenance when the guard railing falls down, thereby reducing the road potential safety hazard.

Description

technical field [0001] The invention relates to the field of safety protection fences for roads and bridges, in particular to a safety protection fence for roads and bridges. Background technique [0002] Both sides of the expressway and both sides of the bridge are often provided with safety barriers to prevent the car from colliding to the outside of the road when an accident occurs, and to avoid greater casualties. The existing safety barriers installed in the middle of the road have large gaps and lack of light blocking devices, making it easy for the lights of oncoming cars to shine on the driver's eyes, making the driver unable to see the road information clearly and causing traffic accidents. At the same time, most of the existing safety guardrails pass through rigid anti-collision devices, so that the accident car will be seriously deformed when it hits the guardrail, and the injuries to the people in the car will be aggravated. Moreover, when the existing safety gua...

Problems solved by technology

The existing safety barriers installed in the middle of the road have large gaps and lack of light blocking devices, making it easy for the lights of oncoming cars to shine on the driver's eyes, making the driver unable to see the road information clearly and causing traffic accidents. At the same time, most of the existing safety guardrails pass through rigid anti-collision devices, so that the accident car will be seriously deformed when it hits the guardrail, and the injuries to the people in the car will be aggravated. Moreover, when the existing safety guardrails are toppled over, the road Drivers on the road cannot find out in time, which brings huge safety hazards to cars on the road, so a new type of device is needed to solve the existing problems
