Definitions

  • the invention relates to a fire-fighting device with an extinguishing nozzle connected via a pipeline to an extinguishing fluid supply and with an alarm device which emits a warning signal at the start of an extinguishing process.
  • Such devices are installed, for example, stationary in buildings or other devices to be protected against fire.
  • devices are provided which automatically trigger the application of extinguishing fluid in the event of a fire.
  • the alarm devices emit a warning which is perceptible over a greater distance in the form of an acoustic signal. In this way it is ensured that the extinguishing process which begins in an unobserved area and consequently also the fire itself is perceived by persons in the vicinity of the affected area.
  • sprinkleler bells are provided in known sprinkler systems, which are driven in the manner of a turbine by the water flowing through the pipeline in the event of a fire. It is higher for fire fighting devices where gaseous media are used as the extinguishing fluid
  • BESTATIGUNGSKOPIE also known to pass a portion of the gas through a pneumatic siren.
  • Fire extinguishing agents of this type can be used to fight a fire particularly effectively with a low requirement for extinguishing agents.
  • the object of the invention is to provide a fire-fighting device in which, on the one hand, the risk of leaks is reduced and, on the other hand, an effective alarming of the surroundings is ensured at the start of the extinguishing process.
  • a fire-fighting device with a nozzle head connected via a pipeline to an extinguishing fluid supply and with an alarm device which starts at the start of an extinguishing process Issues warning signal, solved, in which the alarm device comprises a pressure-actuated switching device connected to the pipeline, which triggers the warning signal when the pressure prevailing in the pipeline increases.
  • the extinguishing fluid no longer drives the alarm device, but rather a pressure-sensitive switching device connected to the pipeline is used, which detects the start of the extinguishing process characterized by the increase in pressure in the pipeline and triggers the warning signal.
  • a pressure-sensitive switching device connected to the pipeline which detects the start of the extinguishing process characterized by the increase in pressure in the pipeline and triggers the warning signal.
  • the configuration of a fire extinguishing device according to the invention can be used both in systems in which the pipeline is filled with extinguishing fluid under a quiescent pressure, as well as in systems in which the pipeline is dry in the quiescent state of the device.
  • the pipeline can be charged with a gaseous medium, such as air or N 2 , in the idle state, these media being able to be biased under a static pressure to improve the reaction times.
  • a gaseous medium such as air or N 2
  • the alarm device can emit an optical warning signal or an acoustic warning signal. Of course, these signal forms can also be combined.
  • the extinguishing fluid flowing in the pipe network can be used to set a sound body or a membrane in vibration without leaving the pipe system.
  • a variant of the invention which is particularly advantageous for practical implementation is characterized in that the switching device has a pressure-receiving element supported on an elastic support and that the pressure-receiving element moves from its rest position into its release position against the force of the elastic support when the pressure prevailing in the pipeline increases emotional.
  • the elastic support is preferably a spring.
  • the switching device actuates a signal generating device which is driven by stored pressure energy.
  • Signal generation device is independent of externally supplied energy supplies and as such can be easily connected to any point in the pipeline.
  • the switching device opens a pressure accumulator in which the medium driving the signal generating device is stored when the pressure is increased.
  • This pressure accumulator which is independent of the extinguishing fluid supply, supplies the alarm device with the energy required for emitting the warning signal, so that the alarm device, together with the pressure element and the pressure accumulator, forms a completely closed system with respect to the environment.
  • This cover is preferably designed in the form of a rupture disc that only breaks at a predetermined pressure. In this way it can easily be ensured that the alarm device is not triggered by a movement of the pressure element caused in the pipeline as a result of an unintended pressure surge remaining below a certain trigger pressure.
  • Another advantageous variant of the invention which presupposes the presence of a stored pressure energy which is released from the respective pressure accumulator in the event of an increase in pressure, is characterized in that the medium flowing out when the pressure accumulator is open drives a device for generating electrical energy.
  • a hydraulic or pneumatic The driven device then supplies as a generator the electrical energy for the operation of an electrically operated signal device.
  • the invention can be used particularly advantageously in devices in which, in the event of a fire, extinguishing fluid flows through the pipeline at a high pressure above 10 bar, preferably above 70 bar.
  • the suitability of the invention is independent of whether the extinguishing fluid is conveyed to the nozzle by means of stored pressure energy or by pumps, the invention being particularly advantageous in connection with extinguishing systems due to the fact that no external electrical energy is required for its function , in which the extinguishing fluid is available under pressure in pressure accumulators in the event of a fire.
  • FIG. 1 shows a device for fire fighting in rest
  • Fig. 2 shows the device of FIG. 1 during an erase process.
  • the device 1 comprises a pipeline 2 made of a flexible, hose-like or rigid material, which connects a pressure accumulator 3 to a nozzle head 4.
  • a pressure accumulator 3 which is independent of electrical energy, water, for example, is stored as the extinguishing fluid L.
  • the device 1 can also be supplied with extinguishing water via a pump (not shown).
  • the nozzle head 4 is equipped with extinguishing nozzles 5, which atomize the extinguishing fluid into a finely divided extinguishing mist during an extinguishing process.
  • An alarm device 5 is connected to the pipeline 2 adjacent to the nozzle head 4.
  • the alarm device 5 comprises a housing 6, the interior of which is connected to the interior of the pipeline 2 via a connection opening 7.
  • a piston 8 is guided in the housing 6 as a pressure element and has a widened pressure plate 9 on its side facing the connection opening 7. With its side faces, the pressure plate 9 lies tightly against the side walls of the housing 6.
  • a pin-shaped guide element 10 of the piston 8, which is guided through a guide opening 11 at the bottom of the housing 6, is formed on the pressure plate 9 on its side facing away from the connection opening 7.
  • the piston 8 is supported elastically on the bottom of the housing 6 via a spiral spring 12 arranged coaxially to the guide element 10.
  • the guide element 10 At its free end protruding from the guide opening 11, the guide element 10 has a tip 13.
  • the sleeve 14 also holds the head of the pressure bottle 15 tightly enclosed.
  • the opening of the pressure bottle 14 opposite the guide opening 11 is sealed in the idle state by means of a rupture disk 16.
  • a pneumatically operating siren 18 is connected to the interior of the sleeve 14 via a hose connection 17.
  • the pipeline 2 can be filled with extinguishing fluid under a static pressure. This has the advantage that a leakage in the pipeline 2 can quickly detect leaks.
  • the pipeline 2 can also be dry in the idle state or biased with a pressurized gaseous medium, such as compressed air or nitrogen.
  • extinguishing fluid is triggered, for example, by a fire monitor (not shown here) arranged on the nozzle head 4.
  • the pipeline 2 is then fed from the pressure accumulator 3 with extinguishing fluid L under increased pressure (FIG. 2). Due to the associated increase in pressure in the pipeline 2, the piston 8 is moved against the force of the spring 12 in the direction of the rupture disk 16. The tip 13 is in this way over the The idle state between it and the rupture disk 16 moves until it rests on the rupture disk 16. If the pressure in the pipeline 2 and thus the pressure exerted by the tip 13 on the rupture disk 16 exceeds a certain minimum value, the rupture disk 16 breaks and releases the opening of the pressure bottle 15.
  • the gaseous medium stored in the pressure bottle 15 then flows through the hose line 17 to the siren 18, which, driven by the gaseous medium, emits an acoustic warning signal.
