Definitions

  • the invention relates to a fire extinguishing device according to the preamble of claim 1.
  • a fire extinguishing device which shows a fire extinguishing generator, the cylindrical housing of which contains at least one set which generates an aerosol.
  • This set is produced as a shaped body. It contains components from which an aerosol is formed during combustion, which can be used to extinguish fires e.g. in transport facilities or closed building rooms.
  • the performance of each extinguishing generator is designed in accordance with the different requirements in the individual case. This means that in practice a large number of different generators have to be manufactured and kept in stock. Furthermore, there is the difficulty that these known generators do not work in the desired simple manner on e.g. Ceilings of rooms, in housings of fire extinguishing devices or the like can be mounted.
  • the object of the invention is to remedy this.
  • This object is achieved by the training according to the characterizing part of claim 1. It is thus possible in an advantageous manner with extremely simple means to adapt the fire extinguishing device to the most varied of applications by starting from a receiving device (carrier body) which has standardized connection dimensions which correspond to those of the standardized generators. Regardless of the application of the recording device, i.e. e.g. mounting on ceilings of rooms or arrangement in fire extinguishing housings, the use of a single generator type is possible. This enables simple, inexpensive application in the manner of a module.
  • this modular embodiment preference is given to a device in which at least two or more fire extinguishing generators are provided.
  • This design has the main advantage that it it is possible to trigger the individual generators simultaneously, but also one after the other in time, the time intervals, for example in the event of a smoldering fire, being triggered automatically in accordance with the respective signals from the associated sensors.
  • the generators are provided with electrical ignition devices, the structure of which is fundamentally known. Instead, percussion detonators, detonators or the like which are known per se can also be provided for triggering by hand.
  • the receiving device can e.g. be designed as a dome-shaped body, on which the preferably two or more generators are arranged in a radial manner and thus cover different surfaces when arranged on the ceiling of a room.
  • the receiving device can e.g. be designed as a dome-shaped body, on which the preferably two or more generators are arranged in a radial manner and thus cover different surfaces when arranged on the ceiling of a room.
  • a further particularly preferred embodiment is specified in claim 5, thereby simplifying and rationalizing maintenance and also making it possible to re-equip a used fire extinguishing device (fire extinguisher) economically.
  • a used fire extinguishing device fire extinguisher
  • the receiving device is made in one piece with the outer housing, e.g. is produced by deep drawing, then only the generator (s) to be replaced are replaced.
  • the design according to claim 6 is provided.
  • This spacing of the preferably several generators from the outer housing of the fire extinguishing device surrounding them achieves thermal insulation.
  • the embodiment according to claim 7 proves to be advantageous; the outlet opening at the front end can be designed as a nozzle, slot or the like.
  • the outer housing can also be provided with a cylindrical extension.
  • the embodiment according to claim 8 is preferred. This is particularly suitable for quasi-stationary use, for example by is temporarily housed in the hold of a truck, a railroad car or the like. Another application is e.g. possible in the event of forest fires by setting up these devices as required to protect areas that are not yet burning but are at risk, with the triggering again preferably being effected electrically by means of an appropriate sensor system. In principle, however, this extinguishing device can also be attached to ceilings or walls of warehouses, cargo holds in ships or the like.
  • the outflow openings for the aerosol in the lower base area of the fire extinguishing device can be designed as circular openings.
  • slot-shaped openings are preferred, which extend in particular in the longitudinal direction of this base region.
  • the embodiment according to claim 11 has proven to be advantageous, in which the floor insert acts as a deflection device for the aerosol.
  • a pyramidal shape can also be provided in principle. In both cases it is achieved that the stability of this fire extinguishing device is increased considerably, ie the required tilting moment, for example in the form of gusts of wind, is correspondingly increased for knocking over these fire extinguishing devices positioned in the terrain.
  • the invention is explained in more detail below with reference to exemplary embodiments in the drawings. Each show in a more or less schematic representation
  • Fig. 1 is a fire extinguishing device for mobile use, partially in
  • FIG. 6 shows a variant of FIG. 1,
  • FIG. 7 shows a further variant of FIG. 3,

  • FIG. 9 shows a cross section along the line A-B in FIG. 8.
  • a hand-held fire extinguisher has the receiving device 1, which is designed as a plate-shaped carrier 2.
  • the receiving device 1 which is designed as a plate-shaped carrier 2.
  • this carrier plate 2 as more clearly shown in Fig. 2 - three gas generators 3 are inserted, one of which is shown in section, the other is shown in the view and the other generator is omitted.
  • the generators in the preferred form have a circular cylindrical housing 12, are inserted into corresponding circular openings 12 'of the carrier plate 2 serving as connections and are supported with their projecting edge 4 on the carrier plate 2.
  • the mounting of the generators 3 in the carrier plate 2 is explained in more detail with reference to FIG. 2.
  • the spacer ring 6 In the aerosol-generating generator 3, starting from its front, outlet-side end 5, are known
  • the spacer ring 6, the coolant 7 for the aerosol resulting from the erosion, the further spacer sleeve 8, the aerosol-producing set 9 produced by casting, pressing or extrusion and the spring element 10 are arranged one after the other.
  • the base 5 is also provided in a known manner with outlet openings for the aerosol, not shown.
  • Spacer rings or sleeves 6, 8 are made of a material that is temperature resistant when the set 9 burns. Steel is preferably used for this, but brass can also be provided, for example.
  • the housing 12 of the generator 3 is closed at its end facing away from the base 5 with the cover 11, which at the same time serves to receive and hold the ignition device 13. This is designed as electrical ignition, but depending on the application, it could also be triggered manually, e.g. in the form of a blow or tear-off igniter (see FIG. 6).
  • the outer edge 14 of the carrier plate 2 is connected to the outer housing 15 of the fire extinguishing device, e.g. fixed by brazing or detachable, for example by screwing.
  • the distance 17 is provided between the housing 12 of the generators 3 and the inner surface 16 of the outer housing 15.
  • the outer housing 15 is cylindrical in its area 18 surrounding the three generators. This area 18 is followed in the outflow direction of the aerosol by the frustoconically tapering part 19, at the front end of which the outflow opening 20 is provided.
  • the outer housing 15 is double-walled, i.e. it has a heat-insulating space 21 between its two walls.
  • the outer housing 15, each shown in the view, has the handle 22 and the transport and guide handle 23. Both handles are preferably made of heat-insulating material, e.g. Plastic and possibly still made hollow.

  • the generators 3 are in turn attached to the plate-shaped carrier 2, for example by means of the retaining tabs 25 screwed onto the carrier plate 2, which press the protruding edge 4 of the generators 3 against the carrier 2.
  • This arrangement has the advantage that fire extinguishing devices can be designed in a modular design, assuming a uniform, standardized generator type, the number of generators to be used per device being determined once in accordance with the types of power to be offered.
  • the generators 3 can be easily removed with their carrier plate 2 and can be replaced by a new unit consisting of plate and generators. Instead, it can also be provided that only individual generators are exchanged for new ones.
  • This modular structure enables the fire extinguishing devices to be manufactured very economically. The same applies if these are to be provided with new generators after use or after the required very long operating times have expired. Without basically departing from the advantageous modular design, provision could also be made, e.g.
  • the fire extinguishing device according to FIG. 3 has the same gas generators 3 as in FIGS. 1 and 2, which are therefore not explained again here.
  • the outer housing 15 is cylindrical in its area 18 surrounding the gas generators, and indeed double-walled with an enclosed cavity 21. Furthermore, the distance 17 is also provided here between the generators 3 and the outer housing 15.

At its other end, this fire extinguishing device also has a heat-insulating handle 30 shown in the view.
  • FIG. 4 shows a view corresponding to the arrow X in FIG. 3 and is identical in its inner part to FIG. 2, the circlips 24 having been omitted to simplify the drawing.
