Definitions

  • the invention relates to an extinguishing system, in particular for mobile devices.
  • the invention has for its object to provide an extinguishing system that enables a location-independent application of extinguishing agent compared to the known extinguishing agent containers with the simplest means.
  • This object is achieved by an extinguishing agent container with a fluid space for a pressureless fluid and a pressure reservoir for a conveying medium, the fluid space and the pressure reservoir being separated by means of an elastic membrane, so that the fluid space is provided with a locking element via a connection piece connected to the extinguishing agent container, that the pressure reservoir can be filled with a pressure medium via a filler neck or a pressurized gas can be applied to an unpressurized delivery medium and that a mist nozzle is connected directly or indirectly to the neck or to the blocking element as a distributor device.
  • the membrane takes part in the change in volume of the compressed gas cushion - in any position and at the usual accelerations - and also prevents the undesirable effect of re-blowing in compressed gas cylinders.
  • the propellant gas escapes without an extinguishing agent, there is an injector effect at the extinguishing nozzle. This can lead to a fire that has almost been extinguished.
  • Further advantages of the invention are that the printing medium and the extinguishing agent are separated. Especially when water is used as an extinguishing agent, reagents are added to improve the extinguishing ability.
  • pyrotechnic pressure gas generators which only apply the propellant gas pressure when the fire extinguisher is to be activated.
  • the compressed gas generator contains a charge with an electrical ignition element. At Ignition results from the combustion of a gaseous pressure mixture, which is distributed in a pressure-free medium in the pressure reservoir and pressurizes it.
  • An inert gas for example nitrogen, can be used as the pressureless medium.
  • the extinguishing agent containers are usually located where the passenger seat is. If water is used as the extinguishing agent, which is expelled after the activation of the extinguishing system via mist nozzles, then optimal fire protection is guaranteed. With water mist, not only can the fire in the passenger compartment be extinguished, but also a high level of personal protection can be achieved because the suffocating effect of the inert gas is no longer present.
  • the extinguishing system With the extinguishing system according to the invention, after the blocking element for the unpressurized fluid is opened, it is automatically expelled from the extinguishing agent container.
  • the propellant is a stored pressure medium or a pressureless medium is pressurized.
  • the membrane is U-shaped with an opening facing the valve and the open edge of the membrane is attached to the inside of the extinguishing agent container.
  • the extinguishing agent container is made of an upper and a lower part, which are connected to each other.
  • the U-shaped membrane can be attached, for example, at the junction of the upper and lower parts.
  • the extinguishing agent container 1 consists of an upper part 10 and a lower part 11, which are interconnected.
  • a weld seam 15 is provided in the exemplary embodiment according to FIG. 1, a screw connection, an adhesive connection or the like can be provided.
  • a nozzle 6 is provided with a valve 5 as a blocking element.
  • a rupture disk 22 can also be provided as a blocking element (FIG. 5).
  • the lower edge of the upper part 10 has an inwardly extending thickening 12 with an outer recess 13.
  • the upper edge of the lower part 11 includes the recess 13.
  • the inward-pointing thickening 12 is provided with a recess 14 into which the thickened part 15 one Membrane 3 is inserted.
  • the membrane 3 provided with a thickening 16 is fastened within the extinguishing agent container 1 and thus forms an upper fluid space 2 for a pressureless fluid and a lower pressure reservoir 4 for a pressure medium.
  • the membrane 3 can also be fastened by means of a bead 25 and a clamping ring 26 (FIG. 2).
  • a filler neck 7 with a filler element 8 is provided for filling in the pressure medium 4a.
  • a pressureless inert gas 4b can also be used instead of the pressure medium 4a.
  • a compressed gas generator 19 is started, which is connected to the nozzle 7 via a line 18.
  • an ignition device 20 When activated, an ignition device 20 is ignited by a control element 21.
  • the medium in the pressurized gas generator generates a pressurized gas by combustion, which mixes with the unpressurized inert gas 4b and thus transfers the pressure via the membrane 3 to the extinguishing fluid in the fluid space 2 when the volume is increased.
  • the rupture disk 22 When a certain pressure is reached, the rupture disk 22 is destroyed, so that the extinguishing fluid is directed via opening 17, line 23 and a mist nozzle 24 to the source of the fire in the racing car.
  • this is opened via a control device.
  • the pressure gas generator 19 can be attached directly under the extinguishing agent container 1. 1 additionally shows the diaphragm 3 in dash-dotted lines, after which the extinguishing fluid has been discharged. The thickening 16 lies against the opening 17 and closes it.
