Definitions

  • the invention relates to a fire extinguisher, in particular a fire extinguisher for the protection of localized areas of larger objects, of which certain locations should be provided with individual and possibly temporary fire protection.
  • the object of the invention is therefore to propose a fire extinguisher which can be optimally used for locally limited plant areas, which can be attached quickly and safely to practically any plant site and essentially without any special preparatory work, and is also provided with a triggering or monitoring element which automatically carries out the extinguishing process and can initiate remotely if necessary.
  • Fig. 1, 1 denotes an extinguishing agent cartridge which, in the case of a small extinguisher, has a filling volume of, for example, approximately 50 cm 3 and contains, for example, halon, which is at approximately 14 bar pressure and is therefore liquid.
  • a sprinkler 3 is built onto a thread 2 on the neck of the extinguishing agent cartridge 1. This Sprinkler is cut in Figs. 2 and 3 and shown in elevation. It has, as a trigger element, a so-called glass barrel as a bursting body 4, the cavity of which is filled with a liquid which builds up pressure when the temperature rises and which bursts the glass barrel when a predetermined critical temperature is reached.
  • the sprinkler 3 contains a device 5, which can be designed either as a probe for the response signal of the triggering device, or as a detonator 5 which can be activated by remote control, by means of which the glass barrel can be blasted away from its holder.
  • FIG. 2 shows a sprinkler block 6 with a central axial bore 7, in the outer end of which the thread 2 can be screwed onto the neck of the extinguishing agent cartridge 1.
  • the bore 7 tapers to a nozzle section 7 ⁇ , on the axis xx of which the extinguishing agent cartridge 1 is also aligned.
  • a filling valve 8 which is designed as a check valve, not shown.
  • a cone section 9 with a stop shoulder 10 adjoins the nozzle section 7 ⁇ . On the latter there is an O-ring seal 11, which holds the glass barrel 4 in sealing relationship with the sprinkler block 6.
  • This sealing relationship is obtained by screwing a sprinkler basket 12 designed as a counter-holder for the glass barrel onto the sprinkler base 6.
  • the sprinkler basket with a base ring 12 ⁇ has a number (four in the drawing) of the basket base 13 columns that run obliquely upwards to a cap 14, with which they are connected in one piece.
  • the cap 14 contains a center hole 15 for the blunt end of the glass barrel 4 and is domed-concave on its inside.
  • This concave curvature is intended as an impact surface optimize the distribution of the extinguishing agent jet when the sprinkler 3 responds. In this case, the curvature acts like the baffle plate of a conventional sprinkler.
  • the device is commercially available and contains a mini contact in the case of a response signaling device or, in the case of a detonator, an explosive charge which is electrically ignitable and has a firing pin (not shown) driven at right angles to the nozzle axis x-x.
  • a firing pin (not shown) driven at right angles to the nozzle axis x-x.
  • the mounting plate 16 also carries connecting terminals 17 for the associated electrical ignition lead 5 '.
  • the sprinkler described above is preferably part of a small extinguisher with an extinguishing agent cartridge content of about 50 to 100 cm2.
  • a small extinguisher with an extinguishing agent cartridge content of about 50 to 100 cm2.
  • Such a device can be used particularly inexpensively because it can be attached for extinguishing or monitoring purposes without local means.
  • a mounting device which in turn can be attached to the system part to be monitored in a self-adhesive manner.
  • Such a mounting device is shown in FIGS. 4, 4a and 5 and consists (FIGS. 4, 4a) of an L-shaped mounting bracket 21 which carries two pipe clips 22 which are aligned with the outer contour of the extinguishing agent cartridge and which tightly enclose the cartridge.
  • the mounting bracket 21 itself is provided with an adhesive which, in the case shown, is a pair of permanent holding magnets 23 which, when a ferromagnetic base is present, is ideally suited for fastening the device.
  • a block permanent magnet (not shown) can also be used as the magnetic adhesive. If, however, there is a curved ferromagnetic surface, a block of flexible rubber with permanent magnetic elements embedded therein can take its place, for example, the magnetic block having to be attached at a distance from the mounting bracket. Such a possibility is shown in FIG. 5.
  • 21 in turn denotes the mounting bracket, 24 ⁇ the curved mounting surface, 25 a flat magnetic element block which is flexible in the x and / or y direction and 26 three-dimensionally flexible mounting bar, e.g. made of a soft rubber.
