Description
Technical field
The present invention relates to guardrail support device technical fields, particularly relate to a kind of for preventing the bridge of vehicle water falling
Protective device.
Background technique
Traditional Bridge guardrail is generally attached using railing one by one, be commonly encountered when guardrail is our daily trips or
Using the protective device arrived, and Bridge guardrail is even more indispensable protective device, and current Bridge guardrail is all that single line is fixed
Support easily generates rollover by larger external force, abnormally dangerous, and the fixed support of single line bear incessantly it is some compared with
Big natural calamity.Especially when meeting an automobile accident, the impact force of automobile is often very big, it will usually guardrail is impacted it is bad, then
It falls into the water from bridge, for large bridge, after automobile falls into the water, when people salvage, generally requires large-scale engineering machinery
Automobile could be salvaged, moreover, the people in automobile is perhaps because severely injured be drowned already, therefore, it is necessary to design one at this time
Even if kind of guardrail makes automobile break through guardrail still without falling into the trouble for salvaging automobile from water in water, is on the one hand eliminated, separately
On the one hand, the wounded can be timely succoured, avoid wasting time, so that it is not severe injury and is drowned.
Authorized announcement date is that the patent document of " 207295451 U of CN " discloses a kind of Bridge guardrail, the utility model shield
Column can effectively prevent vehicle to cross guardrail, reduce vehicle and fall to caused safety accident under bridge, but there is no solve vehicle
Cross the technical issues of falling into the water after guardrail；Authorization Notice No. is that the patent document of " 207047697 U of CN " discloses one
Kind of Bridge guardrail, this patent document can be with effective protection Bridge guardrails by structures such as cushion, impact bag, neonychiums, and can
With the life security of personnel in multiple security protection vehicle, but still unresolved vehicle falls into the technology in water after crossing guardrail
Problem.
Summary of the invention
The purpose of the present invention is to provide a kind of for preventing the bridge protection device of vehicle water falling, solves automobile and breaks through
Overboard technical problem after bridge guardrail, avoids that driver is overboard or even technology drowned and cannot succour in time is asked
Topic, also avoids the trouble of subsequent salvaging.
