Fire detection and fire extinguishing integrated system in large-scale passenger vehicle
Technical Field
The utility model relates to a fire-fighting equipment field especially relates to a fire detection and extinguishment integrated system in large-scale passenger vehicle.
Background
With the expansion of cities and the continuous development of public transportation, more and more large-scale passenger vehicles are put into operation and use. Meanwhile, fire accidents of large passenger vehicles are frequently caused, and table 1 lists the fire accidents and the dead injuries of various large passenger vehicles in recent years. Due to the characteristics of large fire load and dense personnel of large passenger vehicles, once a fire disaster happens, the fire disaster is often difficult to control. Particularly, the fire disaster can spread to the whole vehicle in a short time and burn and explode to cause large-scale casualties by the fire which is a longitudinal fire aiming at maliciously attacking and recovering the society. Accordingly, the need for a corresponding internal fire suppression system is highly acute. How to utilize the detection technology of putting out a fire in limited carriage space with the intensity of a fire control at the initial stage, the accurate conflagration that extinguishes avoids the human fire or the large-scale conflagration casualties that the riot terrorism attack caused become the problem that awaits a urgent need to solve.
The development of the fire extinguishing system of the large passenger vehicle goes through various design schemes from scratch, but at present, no fire extinguishing system of the large passenger vehicle which is really put into operation in a large scale exists. At present, the popular passenger vehicle fire extinguishing systems in China mainly comprise two types: a fire suppression system for a lightweight liquid reservoir placed in the bottom of a chair, where the liquid reservoir is placed under several seats and activated in the event of a fire to extinguish the fire in an area within a protective radius of the surroundings. The other is a complex liquid storage tank fire extinguishing system arranged below the carriage, namely, a liquid storage tank is arranged below the carriage, the outlet of the liquid storage tank is connected with a pipeline and extends to each part in the carriage, and the spraying is started after a fire disaster happens. However, both of these fire suppression systems have poor space utilization, poor practicality and false alarm problems, and complicated installation piping and high maintenance costs are prohibitive.
