Anti-impact safety bridge

Abstract

The invention relates to an anti-impact safety bridge. The anti-impact safety bridge comprises a bridge body and a bridge mast for supporting the bridge body; a flow discharging passage is formed in the bridge body; the two end parts of the flow discharging passage are in flat shapes; the middle section of the flow discharging passage is in a tall and thin shape; a flow guiding device is arranged at a water outlet end; the flow guiding device comprises a flow guiding shifting wheel, a transmission shaft, a driving shifting wheel and a driving shaft; the driving shaft is in engaged connection with the transmission shaft through an accelerating gear set; the rotation speed of the flow guiding shifting wheel is higher than that of the driving shifting wheel; blades of the flow guiding shifting wheel extend into the flow discharging passage from the lower end surface of the water outlet end; and blades of the driving shifting wheel extend out of the bridge body from the lower surface of the bridge body. The anti-impact safety bridge has the advantages that the structure is novel, the principle is special, the transverse impact force of river water on the bridge body can be effectively reduced on the premise of guaranteeing the supporting capacity of the bridge, the service life of the bridge can be prolonged, and the normal passing of residents is guaranteed.

Description

technical field [0001] The invention relates to the traffic field, in particular, it is a bridge. Background technique [0002] The bridge is one of the important components of the current transportation system. It connects the two sides of the river, which can not only ensure the convenient passage of vehicles and pedestrians, but also meet the smooth passage of ships, effectively improving the efficiency of traffic and transportation; During the drought and flood period, the river level rises during the flood period, and the flowing river water will hit the side of the bridge, which will generate a large lateral impact on the bridge. Long-term impact will easily accelerate the aging or even damage of the bridge; many news reports claim that the bridge was destroyed during the flood period If it collapses, it will cause certain casualties and seriously affect the normal traffic of residents; if too many discharge channels are set up on the bridge body, it will affect the su...

[0002] The bridge is one of the important components of the current transportation system. It connects the two sides of the river, which can not only ensure the convenient passage of vehicles and pedestrians, but also meet the smooth passage of ships, effectively improving the efficiency of traffic and transportation; During the drought and flood period, the river level rises during the flood period, and the flowing river water will hit the side of the bridge, which will generate a large lateral impact on the bridge. Long-term impact will easily accelerate the aging or even damage of the bridge; many news reports claim that the bridge was destroyed during the flood period. If it collapses, it will cause certain casualties and seriously affect the normal traffic of residents; if too many discharge channels are opened on the bridge body, it will affect the supporting capacity of the bridge body and easily cause the collapse of the bridge body; therefore, the current bridge is in There are still some problems in the balance of supporting capacity, discharge and flood control capacity, which pose a certain threat to the safe passage of residents
