Definitions

  • the invention relates to an extinguishing device with a container for receiving a pressurized or pressure-overloaded extinguishing agent and with an outlet formed by an extinguishing nozzle for the extinguishing agent, which opens automatically when a preselected temperature is exceeded.
  • the invention has for its object to show an extinguishing device of the type described, which is suitable, so to speak, as a "mini extinguishing system" for the above-mentioned devices and for other similar devices, which can be manufactured inexpensively and (also by laypersons and / or subsequently, if necessary) simply and without problems can be mounted on the respective device to be protected.
  • an extinguishing device is designed such that the extinguishing nozzle serving to discharge the extinguishing agent is formed by one end of a piece of pipe, the other end of which is connected to the interior of the container Connection is made, and that the pipe section is closed in the region of its one end by a wall which consists of a material or is fastened to the pipe section by means of a material which dissolves or liquefies when a predetermined temperature is exceeded.
  • the extinguishing device according to the invention can be manufactured inexpensively and enables easy assembly, even by laypeople.
  • the extinguishing device according to the invention can also be used very universally, also for directional effects or direct use.
  • the device according to the invention is characterized by small dimensions, so that, above all, an optically non-disturbing attachment of the device to a device to be protected or in such a device is possible.
  • the wall closing the pipe section in the region of its end serving as an extinguishing nozzle is fastened to the pipe section by a eutectic solder material, which on the one hand guarantees a sufficiently secure mounting, but on the other hand also ensures a quick and instantaneous response or initiation of the extinguishing process. Furthermore, the eutectic solder material, which almost instantaneously changes to the liquid state when the predetermined temperature is reached, allows a very precise determination of the temperature at which the extinguishing process is to be triggered by differentiated selection of this material.
  • the extinguishing device shown in the figures which is used in a wide variety of devices and equipment, such as electrical equipment, namely, for example, television sets, amateur radio stations, desktop computers, monitor devices, telephone exchanges, computer printers, computer storage systems, etc., but also, for example, in others, Devices at risk of fire, such as can be used for carburetors for engines for automatic fire monitoring and fighting, essentially consist of a container 1 for holding a pressurized or with Pressure superimposed extinguishing agent and from a blow pipe 2, one end of which is connected to the interior of the container 1 and the other end of which is closed by a cup-shaped cap 3 or 4.
  • a container 1 for holding a pressurized or with Pressure superimposed extinguishing agent and from a blow pipe 2, one end of which is connected to the interior of the container 1 and the other end of which is closed by a cup-shaped cap 3 or 4.
  • powder of different fire classes or a gaseous, preferably liquefied agent such as, for example, halogenated hydrocarbons (in particular Halon R12 B1), is used as the extinguishing agent.
  • the container 1 is similar to an aerosol spray can made of sheet steel by pulling and closed on its side opposite the container bottom 5 by a hinged lid to the outside, to which one end of the blowpipe 2 is fastened in such a way that it does
  • the interior of this tube communicates with the interior of the container 1, but towards the outside at the transition point between the blowpipe 2 and the cover 6 a pressure-tight seal is achieved.
  • the blowpipe 2 is angled in the illustrated embodiment, so that the container 1 can be attached to the rear wall 7 of an electrical device, for example a television set outside and with its outer surface against the rear wall 7, while the angled part of the blowpipe 2 with its other , closed end 2 'extends through an opening 8 into the interior of the device.
  • a hose clamp or a tensioning band 9 is used, which is passed through ventilation slots provided in the rear wall 7 and thereby enables extremely simple assembly, which can even be carried out by laypersons.
  • the blow pipe 2 which is also made of metal, for example copper, widens in a funnel shape at its end 2 'serving as an extinguishing nozzle or merges there into a funnel-shaped section 10, the wall thickness of which compared to the wall thickness of the remaining blowpipe 2 is significantly reduced.
  • the wall thickness of section 10 is only about half the wall thickness of the rest of the blowpipe 2.
  • the closure cap 3 is inserted. It consists of a truncated cone-shaped peripheral wall 11, which rests with its outer surface against the inner surface of section 10, and a bottom 12, which is provided at the end of the closure cap 3 with the smaller diameter and approximately in the region of the transition point between the blowpipe 2 and section 10.
  • the dimensions of the section 10 and the circumferential wall 11 of the closure cap 3 are selected so that the section 10 and the circumferential wall 11 end at a common annular edge 15 on which the closure cap 3 with the aid of a eutectic solder or Solder material 16 is attached to section 10.
  • the solder material 16 is selected so that it melts at a predetermined temperature, for example at a temperature of 90 ° C, so that in the event of overheating or a fire inside the device, the closure cap 3 detaches from the blowpipe 2 and from which now open end 2 'of the blowpipe 2 extinguishing agent can enter from the container 1 into the interior of the fire fighting device.
  • the soldering or the soldering material 16 thus serves as a thermocouple, which the extinguishing process when a predetermined temperature inside the Triggers automatically. In order to avoid delays, the soldering 16 is kept as thin as possible, ie the smallest possible amount of soldering material 16 is used.
  • the insulating and sealing washer 13 naturally ensures, when the closure cap 13 is closed, that the blow tube 2 is sealed at the end 2 ', which means in particular that this termination does not have to be produced by the soldering material 16, which is therefore very low in the desired manner Amount can be used. It is even possible to provide the soldering material 16 continuously only at individual points on the edge 15 and not on the entire edge. In order to ensure that the triggering is as delay-free as possible, the peripheral wall 11 of the closure cap 3 is of course also made with the smallest possible wall thickness.
  • FIG. 3 shows an embodiment of the end 2 "of the blowpipe 2 serving as an extinguishing nozzle, which (design) differs from the design according to FIG. 2 only in that the blowpipe 2 does not have a funnel-shaped section 10, but rather a circular cylindrical one Section 17 of reduced wall thickness merges, in which case the peripheral wall 18 of the cup-shaped closure cap 4 is accordingly not in the shape of a truncated cone but also in the form of a circular cylinder is.
  • the embodiment shown in FIG. 3 corresponds to the embodiment shown in FIG. 2 in terms of its construction and in terms of its properties, so that in FIG. 3 the same reference numbers as in FIG. 2 have also been chosen for the remaining parts.
  • the extinguishing device In order to avoid that when the extinguishing device is triggered or when the closure cap 3 or 4 is released, it is thrown into the interior of the electrical device and possibly leads to damage or short-circuits, it may be expedient to cover the closure cap 3 or 4 with a To connect chain 19 with the blowpipe 2.
  • other means for retaining the closure cap 3 or 4 are also conceivable, for example a collecting basket which catches the released closure cap 3 or 4.
  • additional areas, in particular between the closure cap 3 or 4 and the section 10 or 17, are simultaneously formed, which have a low thermal conductivity and thereby also contribute to a rapid response of the extinguishing device.
  • a test and fill valve 20 is provided at the bottom 5 of the container 1.
  • a signal transmitter which responds to the pressure inside the container 1 can also be provided, which has, for example, an electrical switch which responds to the pressure inside the container 1 via a pressure membrane or another movable element (for example piston) operated plunger is kept closed as long as the pressure in container 1 does not fall below a predetermined lower value.
  • the electrical switch of the signal generator can then be used to automatically switch off the device to be protected or to trigger an alarm when the Pressure in the container falls below the specified lower value and a sufficient extinguishing function is no longer ensured.
