Movable water spray fire extinguishing system for underground road tunnel

Abstract

The invention belongs to the technical field of fire protection and safety, and particularly relates to a movable water spray fire extinguishing system for an underground road tunnel. A movable waterspray fire extinguishing device is arranged on a metal rail of a tunnel wall surface, is communicated with a fire water supply through a metal hose, and is formed by a water spray fire extinguishing system and a driving device; the water spray fire extinguishing system comprises a water spray nozzle, a fire extinguishing pipe, a fire extinguishing water supply pipe, a water supply buffer, the metal hose, a lock adapter, a water delivery pipe, a fire pump and a fire pool; the driving device is formed by a driving motor, an active driving wheel, a driving belt, a driven driving wheel, a limitingwheel and a traveling wheel. The water spray fire extinguishing system provided by the invention is large in fire extinguishing area, fast in fire extinguishing speed and high in efficiency, can realize fixed-point fire extinguishing of the fired vehicles in the tunnel, and overcomes the defects that a traditional fixed fire hydrant is far in distance, difficult in opening and unable to extinguish the fire in time.

Description

technical field [0001] The invention belongs to the technical field of fire protection and safety, and in particular relates to a movable water spray fire extinguishing system for underground highway tunnels. Background technique [0002] In recent years, with the increasing number of cross-sea and river-crossing tunnels in our country, these underground tunnels are the main transportation hubs of a city. Once an accident occurs, it will seriously block the traffic. The various transport vehicles passing through these tunnels carry various items, and sometimes the transport vehicles catch fire. Due to the limited space in the tunnel, the traffic flow is large and the vehicles are dense, traffic jams may occur in the event of a vehicle fire and affect other vehicles, forming a vicious traffic accident of "burning and burning". The evacuation of personnel and fire rescue in the tunnel are also very difficult, which may cause a large number of casualties and property losses. ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problems in the prior art, the purpose of the present invention is to overcome the defects that the existing cross-sea and river-crossing tunnels have insufficient fire extinguishing facilities and cannot fully exert their fire extinguishing effects, and it is difficult for on-site personnel to find fire extinguishing equipment and cannot quickly and effectively extinguish fires. , to provide a movable water spray fire extinguishing system for underground highway tunnels, so as to realize rapid and large-scale fire extinguishing of vehicles on fire in highway tunnels, and at the same time provide water spray cooling for other vehicles close to the vehicles on fire, so as to prevent tunnel accidents Large-scale vehicle fires in the area provide technical support for the protection of people's lives, property and the smooth flow of traffic arteries
