Definitions

  • the subject matter relates to a fire protection device for transitions between cars of rail vehicles with a transition between two cars of a rail vehicle, and a fluid-fed fire fighting equipment.
  • Firefighting in public transport is gaining more and more importance due to legal regulations. Especially in rail transport, firefighting is of great importance.
  • Several 100 passengers are transported in wagons (cars) by rail vehicles. Newer rail vehicles have open transitions between the wagons. This creates very large spaces in which a fire can spread quickly.
  • passengers are likely to carry flammable materials (e.g., clothing, bags, etc.), and fire propagation due to these highly flammable materials can be extremely fast.
  • This object is objectively achieved in that the fire-fighting device has at least one fluid mist nozzle issuing a fluid mist, wherein the at least one fluid nebula is aligned such that the fluid mist is sprayed into the transition.
  • fluid mist systems are particularly suitable for fire fighting in
  • the fluid mist nozzles bring out the fluid in the finest droplets.
  • the fluid nebulizers are pressurized with a fluid under high pressure. It is possible, for example, that a pressure range between 10 and 60 bar is used. It is also possible that a pressure range between 60 and 200 bar is used. Also, a pressure range can already start at 5 bar.
  • the application of the fluid under high pressure causes finest atomization of the fluid at the fluid mist nozzle, thereby cooling the fire compartment.
  • the fluid mist causes a fluid mist curtain to form, through which toxic gases can be at least partially washed out.
  • the fluid mist is thus suitable as a boundary between two spaces, in that the fluid mist forms a curtain as a fog, through which a fire can not pass.
  • the Fluidnebeldüse is objectively aligned such that the fluid mist is sprayed into the transition.
  • the transition by means of the fluid mist forms a
  • Fire barrier through which the fire and the combustion gases can not pass.
  • the combustion gases are at least partially washed out and precipitated by the fluid mist.
  • the materials of the transition are protected by the fluid mist from fire, since the transition in the case of activation of the fire-fighting device is always cooled by the fluid mist.
  • a few fluid nebulizers are sufficient in the region of the transition in order to sufficiently cool it.
  • the fluid mist nozzles for discharging the fluid mist only a small amount of fluid, such as water. For example, it is possible to maintain a fluid mist for 10 minutes with 100 liters of water. Lower amounts of water are also possible. It has been found that the weight saving compared to conventional fire protection devices is enormous. In contrast to additional weights of 300 to 400 kg for fire doors, the firefighting device according to the object, including the fluid reservoir, needs approx. 100-150 kg weight in order to achieve the same fire protection class.
  • the fluid mist nozzle is arranged in at least one carriage in the region of the transition and a spray direction of the fluid mist is aligned in the direction of the transition.
  • the fluid mist nozzle is arranged in the carriage itself.
  • the fluid nebulizer in the car is aligned so that the
  • Fluid mist is sprayed in the direction of the transition.
  • a fluid nozzle designed for this purpose which has nozzle inserts which are aligned in the direction of the transition or the fluid nozzle can be aligned as a whole in the direction of the transition.
  • the majority of the fluid mist can thereby in the Transition be sprayed. For example, more than 20-90% of the fluid droplets reach the transition.
  • the fluid mist nozzle is arranged in the transition.
  • the arrangement of the fluid mist nozzle in the transition on the one hand has the advantage that is generated directly in the transition of the fluid mist.
  • the transition can be made together with the fluid nebulizer, whereby the transition with the fluid nebulizer already has an integrated fire fighting device.
  • the carriages into which the transition designed in this way are installed need not be prepared in a special way. Thus, a combination between such a prepared transition and a variety of cars is possible, with a fire fighting is always guaranteed.
  • the fluid mist nozzle is arranged in the bottom region of the transition.
  • the transition is regularly formed from a flexible outer part, which is delimited by inner linings to the interior.
  • the inner linings are mutually displaceable, so that the transition remains flexible.
  • mutually displaceable base plates can be arranged in the region of the bottom.
  • Fluid nebula nozzle may be arranged, for example, below these floor panels in receptacles provided for this purpose.
  • the fluid mist nozzles may be protected in the bottom area by cover plates.
  • the fluid mist nozzles may be designed such that they cover the cover plates in
  • the cover for example, by the fluid mist itself, which is discharged from the fluid mist nozzles, are released from an anchorage.
  • the fluid nebulizer be arranged in side walls of the transition.
  • the side walls are often visually appealingly arranged by cladding elements.
  • the fluid mist nozzles can be arranged in recesses provided for this purpose.
  • the fluid mist nozzles are arranged behind covers. The covers can be released upon activation of the fluid mist nozzle, for example, by moving the fluid mist nozzle or by the fluid mist itself from the anchors.
  • the fluid mist nozzle is arranged in a ceiling region of the transition.
  • the ceiling area can by a
  • the fluid mist nozzles may be arranged.
  • the fluid nebulizers may also be arranged here in recordings and be covered by covers, so that they are not visible in the normal case. Only in the activation case, the cover is released from an anchorage.
  • a particularly cost-effective solution can be designed in that the fire-fighting device has a central fluid reservoir.
  • a central fluid reservoir is provided, which both the fluid mist nozzles of the car as also feeds the fluid nebulizers of the transition.
  • a central fluid reservoir is provided, which feeds all fluid mist nozzles within the rail vehicle, thus within all or a plurality of wagons.
  • Another aspect which is already based on an inventive idea, is that upon activation of a fluid nebulizer in a first area activation of a fluid nebulizer in an adjacent
  • a fire can be detected in a first car, whereupon at least all of the fluid mist nozzles in the car in question are activated.
  • the fluid nebulizers of the transition adjacent to these carriages can be activated in the fire-lit car next to the fluid nebulizers.
  • the nozzles of adjacent cars are activated, which are directly facing the transition, which is closest to the fire.
  • an activation of all fluid mist nozzles in the car, in which the fire prevails and at the same time the automatic activation of the nozzles in the carriage adjacent to this transition is possible.
  • other nozzles can be activated, which are arranged in the adjoining car.
  • nozzles of the adjacent carriages associated with the transition and / or close to the transition are activated. It is also possible that upon activation of the nozzles in one transition, the nozzles in the adjacent cars are activated, at least the nozzles that are closest to the transition.
  • a valve controller may be coupled with fire detection. Also, it is possible that By means of check valves, the areas are supplied with fluid accordingly.
  • the fire-fighting device has fire detection means for detecting a fire in the transition.
  • this fire detection means a fire can be detected separately for each transition.
  • the fire detection means may be arranged in the transition.
  • the fire-fighting device has at least one area valve connecting the fluid-mist nozzle to the central fluid reservoir. This area valve is necessary in order to selectively apply fluid to individual fluid mist nozzles or groups of fluid mist nozzles. If a fire is detected in a gangway or in a wagon adjacent to the gangway, the divisional valve of the transition where the fire was detected or adjacent to the wagon where the fire is located may be opened, whereupon the fluid nebulizer (n ) of the corresponding transition is acted upon with fluid. According to an advantageous embodiment, it is also proposed that the fire-fighting device has a local fluid reservoir, such that a fluid reservoir is provided for each transition.
  • This local arrangement of a fluid reservoir at the junction has the advantage that a transition can be equipped with an integrated fire fighting device.
  • a transition can be arranged independently of fire fighting equipment of the rail vehicle to the car of the rail vehicle and already includes a fire barrier.
  • the local fluid reservoir can be made small, which makes it possible, for example, to store only a small amount of fluid per transition. Since in a transition only a small number of fluid mist nozzles, for example, only in the ground, only in the side wall or only in the ceiling area, or in a combination of these three areas are present, only a corresponding amount of fluid for a certain firefighting time must be carried.
  • the fluid reservoir should be placed invisibly for the passengers in the transition. For this reason, it is proposed that the local fluid reservoir is arranged at the bottom of the transition. In this case, the fluid reservoir can be arranged, for example, in the underbody, outside the passenger area. It is also possible that the fluid reservoir is arranged on an outer wall of the transition, whereby it is also easy to reach for maintenance purposes.
  • the local fluid reservoir is arranged in the ceiling region of the transition.
  • the fluid reservoir for example, above the Ceiling paneling or be arranged in the outer area of the transition.
  • maintenance is associated with little effort, because in the interior no panels would have to be removed.
  • the fire-fighting device has a fluid supplying the fluid nebulizer pressure pump.
  • the pressure pump can be activated upon detection of a fire by a detection means.
  • the pressure pump then pumps the fluid through a pipe distribution to the fluid nebulizer whose range valve is open.
  • the pressure pump can produce, for example, pressures between 5 and 200 bar.
  • the pressure pump is a pneumatic pump arranged in any case in the rail vehicle.
  • a pneumatic pump is regularly arranged in a railcar of a rail vehicle. This can be switched, for example via a valve in case of fire such that in case of fire, the air pressure generated by it is passed via a pipe to the fluid reservoir and there drives the fluid to the fluid mist nozzles.
  • the fire fighting device has a high pressure fluid reservoir.
  • This may for example be a high-pressure cylinder, which has a capacity of 50 1.
  • this high-pressure cylinder may be filled to 2/3 with fluid and 1/3 with compressed air.
  • the compressed air drives the fluid out of the high-pressure cylinder.
  • the high pressure cylinder may be biased at high pressure, for example, for example between 50 and 200 bar.

  • the fluid mist nozzles 4a, 4b, 4c are arranged in the carriages 2a, 2b.

In the carriages 2 a, b, substantially no fluid mist is sprayed through the fluid mist nozzles 4.
  • the fluid reservoir 6 may be, for example, a high-pressure cylinder. It is also possible for the fluid reservoir 6 to be equipped with a pressure pump (not shown) which, in the activation case, drives the fluid via the pipeline to the fluid mist nozzles 4.
