Description

An intelligent mobile fire-fighting device for bridge fire-fighting

technical field

The invention relates to the technical field of bridge fire protection, and more specifically relates to an intelligent movable fire-fighting device for bridge fire-fighting.

Background technique

At present, the fire extinguishing devices on each bridge are limited to a few fire extinguishers, and there is no system, which is far behind the demand; because the bridge is relatively high, the bridge deck is open, and the wind speed is relatively high, when a fire occurs, it will expand in a short time The burning area will completely burn down a car in just 10 to 20 minutes, and relying on several fire extinguishers cannot solve the problem at all. And every summer is a period of frequent car spontaneous combustion accidents. Gasoline leakage caused by careless maintenance of the car, leakage of electricity caused by aging lines, short circuit, etc. may cause spontaneous car combustion. Once a spontaneous combustion accident occurs, the front car cover must not be opened without fire-fighting measures to avoid the acceleration of combustion. Dry powder fire extinguishing agent cannot be sprayed directly on the flame surface, so the car owner can only watch the car burn down, and the car has become a pile of scrap iron when the firefighters arrive.

Even if the car spontaneously ignites on the bridge and immediately calls the police, the crowded lanes on the commuting bridge also make it impossible for fire trucks to arrive at the scene immediately and delay the best time to extinguish the fire; Car owners and pedestrians have brought serious safety hazards. Car spontaneous combustion incidents on bridges are not uncommon. Once such incidents occur, traffic jams will be caused, and some explosions will even destroy the bridge deck, resulting in more serious economic losses.
