Description
Technical field
The utility model belongs to technical field of fire control, particularly a kind of train fire prior-warning device.
Background technology
Train, the i.e. rail vehicle with multiple connection compartments, such as train, high ferro, subway.Particularly motor-car, compartment
Density of personnel is big, activity space is small, and train is in high-speed motion state, should not be stopped in the short time, and fire is evacuated after occurring and rescued
Help that difficult, fire development is fast, difficulty of putting out a fire to save life and property.To prevent the generation of fire, some fire fighting devices are generally provided with ON TRAINS, such as
Hand-held fire-extinguisher, fire isolating door etc..Best fire-fighting method is can to find to agree that fire can be led in time for fire
Hidden danger, that is, carry out fire alarm.The fire of such as electric equipment is due to that the excessive temperature rising of current anomaly is caused mostly
Insulant is on fire, but before on fire, with the rise of temperature, these insulators can distribute substantial amounts of pyrolysis particle, for example
The polyvinyl chloride of electric wire（PVC）Insulation sheath and the insulating sheath for protecting electrical equipment（ABS materials）Pyrolysis can be distributed after heated
Particle, just as the smell of burning smelt sometimes in life.Other fire is sometimes what the combustible that passenger's violation band gets on the bus was caused, especially
It is some volatile fuel gas, such as oil, alcohol are insufficient due to burning when other material is just on fire, meeting of burning
Substantial amounts of CO etc. is given out for clean-burning gas, this gas is not only poisonous, is also the signal that burning occurs, it is possible to use
This feature timely carries out early warning to the burning just occurred.
Utility model content
The purpose of this utility model is there is above mentioned problem for existing technology, it is proposed that a kind of train fire early warning dress
Put, this train fire prior-warning device can carry out quick early warning to disaster hidden-trouble, and disaster was eliminated in the budding stage.
The purpose of this utility model can be realized by following technical proposal：A kind of train fire prior-warning device, including fire
Calamity early warning system, fire extinguishing system, the gas detector and pyrolysis particle that telling fire early-warning system includes being arranged in compartment are visited
Device is surveyed, gas detector is used for the detector for detecting pernicious gas, such as fuel oil, alcohol or CO that fuel gas or burning are produced.
When the amount that gas detector or pyrolysis particle detector detect corresponding gas or particle exceedes predetermined value, fire-alarm hair
Go out alarm, attendant has further checked whether disaster hidden-trouble, decide whether to open fire extinguisher.If being pyrolyzed particle detector inspection
Measure pyrolysis particle concentration increases extremely, then reduces the electric power in compartment, for example, turn off several light, if pyrolysis particle is dense
Degree then reduces, then explanation is that compartment electric system has disaster hidden-trouble, and electric system is overhauled in time.
Train head and train tail are provided with gas detector outside compartment, for detecting the gas outside compartment.By outside compartment
The detection data of detector and detector in compartment are compared, if the detectable substance concentration outside compartment is higher than compartment
Interior concentration, then improve the detectable substance concentration alarm threshold value in compartment, detection of gas outside the compartment at the headstock tailstock compared in real time
The data of device, if the detectable substance concentration at headstock first increases, illustrate that train drives into detectable substance high concentration region, at this moment improve compartment
Interior warning concentration threshold value, if reduced after detectable substance concentration at the tailstock, illustrates that train is sailing out of detectable substance high concentration
Area, at this moment starts to reduce the warning concentration threshold value in compartment.Because when train enters the area of haze or burning straw etc. sometimes,
It is likely to result in the false alarm of detector.
Preferably, in above-mentioned train fire prior-warning device, gas detector passes through water outside the compartment at train head
Flat air inlet pipe is opened on the arcwall face windward of headstock with UNICOM outside compartment, the air inlet of horizontal air inlet pipe, vertical-horizontal air inlet pipe
It is linked with piston tube, the upper port of piston tube is opened in the junction of headstock arcwall face and headstock top surface windward, the upper end of piston tube
Mouth is fixed with the first filter screen, and the cylindrical plag slidably along piston tube is provided with piston tube.Compartment outer gas at train tail
Horizontal piston pipe is linked between bulk detector and the arcwall face of the tailstock, vertical-horizontal piston tube is linked with vertical air inlet pipe, hung down
The upper port of straight tracheae is opened on headstock top surface, with the setting plug slided in the horizontal piston pipe of vertical air inlet pipe intersection
The second filter screen is fixed with son, horizontal piston pipe, back-moving spring is provided between plug and the second filter screen.According to air force
Learn, when train is run at high speed, air pressure on the windward side of headstock is high, the junction gas of headstock arcwall face and headstock top surface windward
Force down so that cylindrical plag is moved up along piston tube, open horizontal air inlet pipe, outside air is entered gas detector, piston
The first filter screen in pipe plays a part of preventing cylindrical plag from flying out, and when train stops, cylindrical plag, which is fallen, blocks horizontal air inlet pipe.
When train is run at high speed, the air pressure on the arcwall face of the tailstock is low, and the arcwall face of the tailstock and the junction air pressure of tailstock top surface are high,
So that plug compression reseting spring, opens vertical air inlet pipe, outside air is entered gas detector, when train stops,
Back-moving spring makes plug reset to live vertical air inlet pipe plug.
Preferably, in above-mentioned train fire prior-warning device, the air inlet pipe of compartment air intake pump and compartment exhaust pump
Blast pipe is provided with gas detector and pyrolysis particle detector, compares gas or combustible particles in turnover cabin air
Change in concentration, if concentration increase, illustrates there is disaster hidden-trouble, warning system sends alarm.
Preferably, in above-mentioned train fire prior-warning device, the system also includes broken glass device, fire alarm automatically
Device, fire evacuation indicate system, emergency broadcase system, fire resistant doorsets Surveillance center, are provided with flame sensor on broken glass device automatically.
When there is flame, obtain the automatically broken glass device at the minimum flame sensor of flare up fire intensity and start vehicle window explosion, just
Fled from personnel, reduce combustion-supporting effect of the outdoor air to burning again.
Compared with prior art, this train fire prior-warning device has advantages below：
The utility model gas detector burn occur at the beginning of i.e. send alarm, be easy to by fire suppression rudiment shape
State, using combustible particles detector, realizes the strick precaution to electric equipment fire.
