Description
The present invention relates to a kind of fire-fighting system that is used for the tunnel, it has a kind of fixed extinguishing device.
Increasing long tunnel, especially vcehicular tunnel have also increased the risk of breaking out of fire in these tunnels, and it may become disaster in many cases.The experience of recent years shows, automobile takes place in a vcehicular tunnel catch fire and in minutes just may produce huge heat, thereby flame is jumped on the adjacent automobile and the formation conflagration.The gas that heat that produce this moment and burning produce acts on the personnel in this tunnel, and this is very harmful dangerous for health, even causing death often.Tunnel fire hazard in 1999 not only makes the shock of the public and official, and the scheme of having pointed out also not prevent and treat at present this fire system and device in other words.Therefore urge the tunnel operator to replenish and be equipped with effective firebreak device, should consider with such system and device when designing then that to new equipment wherein so-called effectively firebreak device is meant a kind of fire-fighting system that is coupled with fire alarm existing tunnel device.
The fire suppression water sprinkler device that under some several applications situations, is disposed and without practice test in the past.When wind speed surpassed 2.5 meter per seconds, as tunnel fan was caused, the spray water device action and often moved in the position of mistake too late automatically.Owing to open the spray water device too late thereby can't put out a fire and because the strong atomizing of water has reduced visibility and EGT is sharply raise, this just many problems occur when being evacuated.A large amount of in addition fire extinguishing water has formed the combustible liquid in a beach again, and they are uncontrollably stretched and come.Point out also that simultaneously the fire extinguishing of spray water device is very little for the effect on burning things which may cause a fire disaster ground, this is because flame is subjected to the obstruct protection of body of a motor car and is in the water spray shielded area.Wind has been agitated strongly to fight water droplet has been dispelled simultaneously.
The up-to-date safety analysis of relevant tunnel fire hazard thereby requirement realize following protection purpose:
The flame intensity in place reduces to catch fire;
Cool off the surrounding environment in the place that catches fire;

Smog thing in the flushing flue gas is to guarantee enough visuals field.
This protection target should be able to make relevant personnel that the time enough and the visual field are arranged in ignition zone, so that guarantee safety and operational strength (fire brigade) is pushed away closely to the place that catches fire with being safe from danger.
Should illustrate a kind of fire-fighting system that is used for tunnel, especially vcehicular tunnel by the present invention, this system satisfies above-mentioned protection purpose as far as possible to a great extent.
Solving this method of offering the challenge according to the present invention is that the sprinkler system that fixed fire-extinguishing unit can be activated by a kind of part constitutes, this sprinkler system has a main-supply road and a water storage device, and wherein water storage device just is made of the main-supply road.
The local extinguishing device that can activate is the prerequisite that the deposit of the use of extinguishing chemical and extinguishing chemical can both be kept within limits, and the extinguishing ability that sprinkler system reached is enough to make automobile to catch fire to put out or it is restrained.Water storage device just can needn't adopt big and expensive water tank when the long tunnel with the main-supply road.
Design fire-fighting system like this by the present invention, enough to restrain flame longways, so that fire brigade can enter.Because start described fire especially also is to think the catastrophic scale that reached, because the temperature in the tunnel is very high, also impossible even fire brigade only is advanced near the burning things which may cause a fire disaster ground.

Form of implementation by the third preferred fire-fighting system of the present invention is characterised in that, there is a kind of sniffer to be used for the place that catches fire is detected accurately, and when sniffer moves, just makes sprinkler system activate action in the relevant fire extinguishing section and in the fire extinguishing section at two direct neighbors.
Form of implementation by the 4th kind of preferred fire-fighting system of the present invention is characterised in that the water capacity of water storage device can guarantee to carry out 30 minutes fire extinguishing in described fire extinguishing section.
Form of implementation by the 5th kind of preferred fire-fighting system of the present invention is characterised in that the main-supply road is divided into many parallel pipelines, and a kind of fluid power jockey is arranged at least one position between these pipelines.
Form of implementation by the 6th kind of preferred fire-fighting system of the present invention is characterised in that at the two ends on main-supply road a gas-loaded accumulator is arranged respectively, and these two gas-loaded accumulators can come into operation selectively.
Another preferred form of implementation by fire-fighting system of the present invention is characterised in that sniffer constitutes by a kind of linear thermal warning system and a detection cable that is installed on the roof of a tunnel, perhaps is made of a kind of video smoke detection system.
Preferably design sprinkler system like this, make the water spray process at the beginning than after about 5 to 10 minutes, a higher nozzle exit pressure being arranged.
The present invention will be described in detail at the embodiment shown in unique accompanying drawing for following basis: the accompanying drawing schematic representation general status in tunnel 1, this tunnel equipped one the cover fire-fighting system, it is made up of fire detecting arrangement and extinguishing device.Fire detecting arrangement is a kind of (FibroLaser-Siemens construction process joint-stock company of linear thermal warning system of FibroLaser type, Cai Boluosi branch, the registration mark that claimed Cai Boluosi joint-stock company in the past), this system mainly is made up of a glass fibre cable 2 and a measuring instrument 3 that comprises a LASER Light Source and a photoelectron receiver that is contained on the roof of a tunnel.
The optocoupler that is produced by laser instrument is connected into 2 li on glass fiber cable rope and advances on its longitudinal direction.The change of quartz glass density has caused a kind of scattering continuously (Rayleigh-scattering), and this causes preventing laser again.Because another light scattering, promptly so-called Raman scattering have also appearred in the vibration of the thermal grating of glass material.
The sub-fraction scattered light act within the angular aperture of waveguide and not only forwards to and also on backward directions, all expand and come.Scattered light can confirm with a photoelectric seismometer, by just can determine local glass fibre temperature to the analyzing and processing of scattering strength.Local resolution ratio along the variations in temperature of glass fibre cable 2 is to realize by the decay of measuring waveguide light.The size of flame is the function of the cable sections of heating: the flame that the flame that the short cable sections that has heated is corresponding less, the long cable sections that has heated are then corresponding bigger.
Process and analyzing and processing at 3 li signals of measuring instrument the photoelectron receiver.Analysis and processing unit 3 is connected on the system centre 4, and the control of fire-fighting system is just carried out in this system centre.System centre 4 not necessarily will form a construction unit certainly, and it both linked to each other with fire detecting arrangement, also linked to each other with extinguishing device.From system centre 4 connection to center, tunnel 5 is arranged in addition, in this tunnel, compiled the whole control and the monitoring device in tunnel 1 and carried out necessary demonstration, carry out necessary action simultaneously.This action is personnel's information in the control of control, the gas extraction system of control, the Emergency Light of point duty, ventilating system and the tunnel for example, these action are by device acoustics and/or optics, for example luminescent screen in other words loudspeaker carry out.Center, tunnel 5 also links with stand-by power, so that can report to the police in use.Also be related from system centre 4 to fire brigade, so that when breaking out of fire, report to the police automatically.
Another kind of optionally scheme is that fire detecting arrangement can be made of video smoke detection system, and there are some cameras 6 in this system, has wherein only represented a camera in the accompanying drawings.This camera, as they in most of tunnels, be mounted for monitoring traffic, they can form with a suitable microprocessor and the transformation of an appropriate signals treating apparatus, thereby can carry out Smoke Detection automatically according to image recording.For example 00/23858 li this suitable system has just been described, herein with reference to its disclosed content at US-A-5237307 and WO.Stylus 6 also is connected with system centre 4.During breaking out of fire, equally as linear thermal warning system 2, video smoke detection system just sends an alarm.This alarm confirms that by the dispatcher at 5 li at center, tunnel this can realize according to the image of camera 6 easily, put out a fire then.The certain hour that also can lag behind after fire-fighting system action was for example automatically put out a fire in 90 to 120 seconds again, this be during the Delay Process at the center, tunnel under 5 li situations that do not have what reaction just like this.
Extinguishing device is a kind of so-called sprinkler system, and it has the nozzle 9 that is connected on the main-supply road 8 through the opening device that is expressed as section valve 7 and is used for sending fine liquid particles forth atomizing.Section valve 7 can be operated independently through one section control piper 14 that is connected on the system centre 4.Main-supply road 8 is connected a water storage device for example on water tank.With water transport to the equipment of nozzle 9 are gas-loaded accumulators 10, and it is made up of some gas bombs 11, and nitrogen or air wherein for example are housed, and pressure is 200bar.But also can use bigger gas storage tank, pressure is then lower.
Gas cylinder 11 is connected on the pressure piping of a guiding water storage device through valve 12.This pressure piping has a choke valve 13, makes the discharge pressure in the pressure piping thereby also makes main-supply road 8 interior discharge pressures be throttled to the nozzle exit pressure an of the best by this choke valve.A kind of like this sprinkler system has just been described, herein with reference to its disclosed content in european patent application Nr.0097647.7.Section valve 7 and valve 12 equally can be via control piper 14 operations.
For long tunnel, when each tunneltron is divided into described attack area, in these attack areas, can carry out local fire extinguishing, so desired protection purpose could realize.If do not have such attack area will supply water for simultaneously long tunnel construction sections so, can make the consumption of water very big like this.The test of expansion shows that a kind of so optimal and length of attack area is approximately 30 meters.When fire extinguishing, always there are three attack areas to be supplied to water, just zone of alarm and former and later two attack areas that are close to.
The water of all storages all is accumulated in 8 li on main-supply road when length of tunnel surpasses 2 kilometers, and this pipeline has been equipped chemistry and given treated water (having added the water additive AFFF that soaks) and keeping stand-by state as accumulator.Arranged that between main-supply road 8 and choke valve 13 volume is about 2 meter 3 balancing tank.It is 300 to 400 millimeter that the diameter on main-supply road 8 is paid the utmost attention to, thereby every kilometer pipeline can store about 100 meters
3Water.The gas storage that gas-loaded accumulator is 10 li should design like this, so that the water yield required in 30 minutes is provided in the attack area of these three activation.The advantage of this layout is than after about 5 minutes higher nozzle exit pressure being arranged when beginning the overflow water spray.Therefore at the beginning the time, just put out a fire with more water during the stage, enter up to fire brigade than maintenance.Nozzle exit pressure for example reaches 9bar during beginning overflow water spray, and about 5 crust (bar) keep-up pressure.Supply water in the attack area of these three activation actions, always for all nozzles 9 simultaneously.
For the gas that overflow when water spray flowed into is unlikely to the water in Open valve 7 scopes of 8 inherences, main-supply road is squeezed to walk, make the joint of valve 7 be contained in the bottom on main-supply road 8.This layout always guaranteed with water and also certainly not gas be depressed into nozzle 9.Respectively there is a gas-loaded accumulator 10 at the two ends that are preferably in main-supply road 8 as added security, it and the independent mutually overflow water spray of just can realizing of other accumulator.If fire brigade enters too late second gas-loaded accumulator come into operation.When fire extinguishing, advantageously always make and leave farther gas-loaded accumulator 10 startings of attack area that activate action.
Main-supply road 8 can be divided into a plurality of parallel pipes that have than minor diameter.This must according to the variation in tunnel on one or more position each other fluid power couple together.Connect by this fluid power and can stop that pipeline becomes dry anhydrous in activating the attack area scope of action.This method that main-supply road 8 is divided into many parallel pipelines especially recommends to be used in acclive tunnel.
Self-evidently also can replace sprinkler system with a kind of automatic water system, perhaps also subsidiary have a thin nozzle.But compare sprinkler system with automatic water system a series of advantage is arranged, these advantages seem it especially to be fit to be applied in the vcehicular tunnel.These advantages are mainly that extinguishing ability is big, fire extinguishing water is to the effect on burning things which may cause a fire disaster ground and sprinkler system is moved on correct position, and the burning gases of outflow this moment are washed strongly through the length of a protection zone at least and cooled off.
