Abstract

The utility model discloses a fire extinguishing system for the bridge, which relates to the fire fighting technical field. The utility model is to solve the fire fighting technical problems for the bridge. The fire extinguishing system comprises: a water supply section composed of a pump driven by a motor, a check valve, a water inlet and a fire fighting water pipe. The fire fighting water pipe arranged on the bridge is connected with the water inlet directly from the river water via the check valve and the pump arranged under the bridge on the ground. A fire fighting box section comprises a plurality of fire fighting boxes on the bridge. Each fire fighting box is composed of a fire fighting hose, a water valve, a spraying gun and a switch button. The spraying gun is connected with the fire fighting water pipe via the fire fighting hose and the water valve. The switch button for starting the control system is arranged on the spraying gun. The utility model can make full use of the water resource under the bridge, control and extinguish the fire disaster on the bridge in time, and eliminate the danger before the fire fighters come, so as to reduce the loss to the minimum level.

Description

The bridge fire extinguishing system

Technical field

The utility model relates to the fire extinguishing system technology, particularly relate to a kind of by gauge tap on bridge, the river pump under the bridge to bridge floor, thereby the bridge fire extinguishing system that the fire on the bridge is eliminated.

Background technology

Extinguishing device on each bridge only is confined to several fire extinguishers at present, does not form system, and this does not catch up with demand far away; Because bridge is than higher, bridge floor is open, and wind speed is bigger, and fire will enlarge burning area when taking place at short notice, a car will be burnt fully in short 10～20 minutes, can not deal with problems by several fire extinguishers at all.And all be the multiple phase of self-burning of vehicle accident annual summer, and gasoline leaks, aging circuit causes that electric leakage, short circuit or the like reason all may cause self-burning of vehicle owing to the repair and maintenance of not noting car at ordinary times cause.Incidents of spontaneous combustion is in case take place, when having fire protection, must not open preceding car bonnet, avoid the quickening of burning, but the time one is long, because preceding car bonnet at high temperature is out of shape, can't open preceding car bonnet again, so can't directly be sprayed onto on the flame front with conventional foam or powder extinguishing agent, therefore, the car owner can only like soon that car is burnt, and automobile had become the scrap iron a pile when the fire fighter came.

Even just report to the police at once when spontaneous combustion takes place on bridge automobile, incured loss through delay the best opportunity that stamps out a fire owing to track crowded on the bridge on and off duty also makes fire fighting truck to be on the scene at once; During the self-burning of vehicle that has even can set off an explosion, brought serious potential safety hazard for the car owner and the pedestrian that passes by on one's way.The self-burning of vehicle incident that takes place on bridge is of common occurrence, and this type of incident will cause traffic jam in case take place, and the blast that has even can damage bridge floor brings serious economy loss more.

The utility model content

At the defective that exists in the above-mentioned prior art, technical problem to be solved in the utility model provides a kind of bridge fire extinguishing system that can eliminate vehicle fire on the bridge fire, particularly bridge timely and effectively.

In order to solve the problems of the technologies described above, a kind of bridge fire extinguishing system provided by the utility model comprises:

One water supply part is made up of electric motor driven water pump, check-valves, water inlet, fire extinguisher canvas hose etc., is installed in check-valves, the water pump of fire extinguisher canvas hose through being installed in land under the bridge on the bridge, connects the water inlet of directly taking from river;

The Fire Hose part is provided with several Fire Hoses on bridge, each Fire Hose is made up of fire hose, water valve, spray gun and shift knob etc., and spray gun connects fire extinguisher canvas hose through fire hose, water valve; Establish on the spray gun and be used for the shift knob that control system starts.

During fire extinguishing, the water source of bridge fire extinguishing system is directly taken from the well that connects river, filters the back through water inlet and is extracted on the bridge floor by water pump, uses for the bridge fire extinguishing system.

Further, by the equidistant guardrail that is arranged on the bridge floor both sides of described Fire Hose.

Further, described water inlet is provided with screen pack.

The bridge fire extinguishing system of utilizing the utility model to provide, directly take from river and to be extracted into fire fighting supply structure on the bridge floor owing to adopt by water pump, and the guardrails of both sides side is provided with a Fire Hose every a segment distance on bridge, when fire (as self-burning of vehicle etc.) being arranged when taking place on the bridge, can find Fire Hose nearby, open shift knob, in time start this bridge fire extinguishing system, make motor and pump working under the bridge, water under the bridge is extracted on the bridge floor, use for fire extinguishing, thereby utilize the favourable resource of river under the bridge, the fire on the bridge was put out in the shortest time, dangerous situation is just controlled first constantly, the condition of a disaster loss is reduced to minimum level, has also improved the safe extinguishing property of bridge simultaneously.

Description of drawings
