Bridge capable for realizing impact protection after automatic inflation

Abstract

The invention discloses a bridge for realizing impact protection after automatic inflation. The bridge comprises a bridge body, the bridge body is fixedly connected to the ground, a protection mechanism used for automatic impact protection is arranged in the bridge body, the protection mechanism comprises pressure cavities which are in bilateral symmetry and are provided with upward openings, andpressure blocks are slidably connected into the pressure cavities; the lower end of the pressure block is fixedly connected with a pressure spring; the lower end of the pressure spring is fixedly connected with the lower inner wall of the pressure chamber; and the bridge is internally provided with reset cavities which are symmetric in the left-and-right direction and are communicated with outside; the device has the advantages that the device is simple in structure and convenient to use, vehicles with accidents can be protected, excessive damage due to collision can be prevented, and the bridge is safer. The device can detect the height of a water line, when the water line is too high, vehicles are prohibited from passing, accidents are prevented, in addition, the device can lift the protection plate when collision occurs, the vehicles are prevented from turning out of a bridge and falling into a river, the follow-up rescue difficulty is increased, and the rescue time is prolonged.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a bridge with automatic inflation and impact protection. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. When an accident occurs on the bridge, the damage caused is more serious. The width of the bridge is limited. Once an accident occurs, the bridge cannot continue to be used normally. Serious Affects the traffic of vehicles, and accidents on bridges are often more serious. Vehicles are easy to fall into the river, which not only increases the difficulty of assistance, but also pollutes the river with parts on the vehicle; [0003] In addition, the bridge is erected on the river. Once the river's water flow exceeds the bridge, it will affect the traffic of vehicles and be more prone to danger. Contents of the invention [0004] The technical problem to be solved by the p...

[0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. When an accident occurs on the bridge, the damage caused is more serious. The width of the bridge is limited. Once an accident occurs, the bridge cannot continue to be used normally. Serious Affects the traffic of vehicles, and accidents on bridges are often more serious. Vehicles are easy to fall into the river, which not only increases the difficulty of assistance, but also pollutes the river with parts on the vehicle;

[0003] In addition, the bridge is erected on the river. Once the river's water flow exceeds the bridge, it will affect the traffic of vehicles and be more prone to danger.
