Definitions

  • the invention relates to a method for triggering pyrotechnic fire extinguishing devices according to the preamble of claim 1 and a thermal tripping system according to the preamble of claim 13.
  • WO 2009/071635 is a thermally initiated trigger mechanism for aerosol fire extinguishing generators described by means of a glass ampoule.
  • This glass ampoule is filled with a liquid whose vapor pressure at a certain temperature becomes so great that it causes the ampoule to burst.
  • a pressure plate is released, which is acted upon by a tensioned spring.
  • the kinetic energy generated by the relaxation of the spring is used to tension a further, inner spring, which is connected to a firing pin.
  • After a defined stretch of the firing pin is released by the release of blocking elements of the pressure plate and proposes, operated by the previously tensioned spring on a mechanical primer, whereby an initial ignition material is reacted.
  • the resulting hot reaction products then cause increased by a booster set the ignition of the pyrotechnic charge.
  • This tripping mechanism enables the use of aerosol fire extinguishing generators in areas where the use of electronic fire detectors is unfavorable or impossible due to its external energy-independent, low-maintenance and safe design.
  • a fire extinguishing device based on a meltable extinguisher conduit made of thermoplastic material, which is connected to at least one pressurized extinguishing agent container so as to be pressurized by it.
  • the extinguishing agent contained in the extinguishing agent container may be gaseous, liquid or pulverulent extinguishing agent.
  • the pressurized, fusible extinguishing medium line made of thermoplastic material is laid in the fire-prone area so that it bursts due to the high temperatures occurring in the event of fire and thus there is an escape of the extinguishing agent from the line.
  • the fusible plastic line is used only for generating and forwarding a trigger pulse to a pressurized fire extinguishing device.
  • the triggering takes place here by the pressure drop generated when bursting the triggering line. If the line pressure falls below the pressure of the extinguishing agent tank, a control valve is actuated, which enables the release of the extinguishing agent through a separate outflow opening.
  • a fire sensor which describes a sensor hose opening under thermal load, the pressure drop triggers an electrical signal, which triggers an initiator on a gas generator.
  • the invention described above offers the use of a hose for fire detection in addition to the advantage of foreign energy independence, a high coverage of the protected space volume.
  • the invention described in the following is based on the object of specifying a method and a thermal tripping system for triggering pyrotechnic fire-extinguishing devices with which an external energy-independent, compressed-gas-controlled extinguishing system is created, which enables rapid detection of fires which are not in the immediate vicinity of the pyrotechnic fire-extinguishing device .
  • the method should offer the possibility of interconnecting several pyrotechnic fire-extinguishing devices in such a way that they are triggered jointly in case of fire.

  • fire extinguishing devices are connected to the triggering line. This gives the possibility to interconnect several pyrotechnic fire extinguishing devices to a system so that they are brought together in case of fire to trigger.
  • the triggering line is connected at least to a volume filled with pressurized medium, which adjusts the pressure in the triggering line and keeps the pressure in the triggering line constant for small leaks in the triggering line not caused by a fire.
  • the volume filled with pressurized medium may be a volume of any type suitable for adjusting the pressure within the trigger line and for compensating for small leaks.
  • the volume may e.g. be an accumulator filled with compressed gas.
  • the medium for pneumatic triggering is a gas and for hydraulic triggering a liquid.
  • a liquid is, for example, an aqueous solution or an oil or a mixture of water and glycol.
  • the gas is preferably nitrogen or air. If a fluid is used to pressurize the triggering system, this fluid may be e.g. be biased by means of a gas pressure pad or a spring-piston system.

  • the triggering line is a fusible tube of preferably a plastic.
  • the triggering line can also be a metal tube with melting in case of fire pipe sections.
  • the elements are fusible, which melts in case of fire due to the thermal stress and thereby causes a pressure drop in the triggering line.

  • the manually or electrically activatable valves are connected in such a way that, when opening, they cause a pressure drop in the triggering line which triggers the ignition mechanism.
  • sensors are connected to the triggering line or to the ignition mechanism, which detect a pressure drop in the triggering line or an activation of the pyrotechnic extinguishing devices and send a relevant signal to evaluation and / or display devices. This allows a trigger register and forward this information for the purpose of alerting and / or system shutdown.
  • the ignition mechanism preferably comprises a mechanical release device, which converts a pressure drop in the triggering line into a proper movement of a component and triggers the ignition process with this own movement.
