Abstract

The invention concerns an improved fire-fighting method and improved fire-fighting device which employ an extinguishing medium-projecting means, in particular the nozzle of a manual extinguisher, a jet of extinguishing medium being released when an activation member is actuated. By virtue of the invention, it is possible in particular for an unskilled person to extinguish fires more effectively when fighting the source of a fire manually using a small extinguisher. According to the invention, this is achieved in that the extinguishing medium is ejected via the discharge nozzle in at least two qualitatively and/or quantitatively different extinguishing medium flows in an asymmetrical distribution adapted to the fire.

Description

"Verfahren und Vorrichtung zur Brandbekämpfung""Fire fighting method and apparatus"
Die Erfindung richtet sich auf ein Verfahren zur Brandbe¬ kämpfung unter Einsatz eines Löschmittelwerfers, insbesonde¬ re einer Löschmitteldüse eines Handlöschgerätes, wobei ein Löschmittelstrahl bei Betätigung eines Aktivierungselementes freigesetzt wird, sowie auf eine Vorrichtung insbesondere zur Durchführung des Verfahrens.The invention relates to a method for fighting fires using an extinguishing agent launcher, in particular an extinguishing agent nozzle of a hand-held extinguishing device, an extinguishing agent jet being released when an activation element is actuated, and to a device in particular for carrying out the method.
Bei der Brandbekämpfung, insbesondere mit Einsatz eines Handlöschgerätes, wird der Brandherd mit Hilfe eines Lösch¬ mittels aus einer Düse, die in der Regel einen Löschmittel¬ strahl erzeugt, bekämpft. Löschpulver auswerfende Düsen sind häufig mit einem sich nach außen erweiternden Trichter aus¬ gerüstet, um eine Pulverwolke zu erzeugen. Wird mit einem Strahl gelöscht, muß die das Handlöschgerät benutzende Per¬ son zur Erhöhung der Löschwirkung Schwenkbewegungen ausfüh¬ ren oder auf andere Weise versuchen, den Löschmittelstrahl dann zu zerstäuben, wenn eine breitere Fläche mit Löschmit¬ tel überstrichen werden soll.When fighting a fire, in particular using a hand-held extinguisher, the source of the fire is fought with the aid of an extinguishing agent from a nozzle which generally produces an extinguishing agent jet. Extinguishing powder ejecting nozzles are often equipped with a funnel widening outwards in order to generate a powder cloud. If extinguishing is carried out with a jet, the person using the hand-held extinguishing device must carry out swiveling movements to increase the extinguishing effect, or must try in another way to atomize the extinguishing agent jet when a larger area is to be coated with extinguishing agent.
Die Regel ist darüber hinaus, daß Handlöschgeräte nur mit einer Art von Löschmittel gefüllt sind. Bei Großlöschanlagen ist es bekannt, aus unterschiedlichen Löschmittelwerfern ggf. auch unterschiedliche Qualitäten von Löschmitteln in den Brandherd einzuschießen.The rule is also that hand-held extinguishers are filled with only one type of extinguishing agent. In large extinguishing systems, it is known to use different extinguishing media throwers if necessary, shoot different qualities of extinguishing agent into the source of the fire.
Beispielsweise aus dem DE-U-1 782 540, der DE-A-1 948 510 oder der US-5 344 080 sind Düsen bekannt, mit denen unter¬ schiedliche Strahlausbildungen möglich gemacht werden, ins¬ besondere hinsichtlich des Personenschutzes, etwa in Art ei¬ ner "Personenschutzbrause". Eine Optimierung des Löschvor¬ ganges selber, d.h. des Löschverfahrens, ist mit den bekann¬ ten Lösungen nicht möglich.For example, from DE-U-1 782 540, DE-A-1 948 510 or US-5 344 080 nozzles are known with which different jet designs are possible, in particular with regard to personal protection, for example in Art a "personal protective shower". An optimization of the deletion process itself, i.e. the extinguishing process is not possible with the known solutions.
Aufgabe der Erfindung ist die Schaffung einer Lösung, mit der die Wirkungsweise sowohl in verfahrensmäßiger als auch in vorrichtungsmäßiger Form verbessert wird, mit der insbe¬ sondere eine ungeübte Person bei einer Brandherdbekämpfung von Hand mit Kleinlöschgeräten in die Lage versetzt wird, effektiver zu löschen.The object of the invention is to provide a solution with which the mode of operation is improved both in terms of the method and in the form of the device, with which, in particular, an inexperienced person is able to extinguish fires more effectively by hand using small extinguishers when fighting the source of the fire.
Mit einem Verfahren der eingangs bezeichneten Art wird diese Aufgabe gemäß der Erfindung dadurch gelöst, daß das Löschmittel über die Abgabedüse in wenigstens zwei qualita¬ tiv und/oder quantitativ unterschiedlichen Löschmittelströ¬ men in dem Brandprozeß angepaßter, asymmetrischer Verteilung ausgeworfen wird. Bei einer Vorrichtung wird diese Aufgabe dadurch gelöst, daß der Düsenkopf der Löschmitteldüse mit wenigstens zwei unter¬ schiedliche Löschmittelstrahle erzeugenden Düsenmündern aus¬ gerüstet ist.With a method of the type mentioned at the outset, this object is achieved according to the invention in that the extinguishing agent is ejected via the dispensing nozzle in at least two qualitatively and / or quantitatively different extinguishing agent streams in the fire process in an asymmetrical distribution which is adapted. In the case of a device, this object is achieved in that the nozzle head of the extinguishing agent nozzle is equipped with at least two nozzle mouths which produce different extinguishing agent jets.
Mit der Erfindung wird erreicht, daß bei der Betätigung ei¬ nes Aktivierungselementes automatisch unterschiedliche Löschmittelströme ausgeworfen werden, wobei je nach Einsatz¬ zweck eines Löschgerätes hier eine Vielzahl von Variations¬ möglichkeiten gegeben sind.It is achieved with the invention that different extinguishing agent flows are automatically ejected when an activation element is actuated, with a large number of possible variations depending on the intended use of an extinguishing device.
Mit der Erfindung ist die gezielte Kombination der Löschmit¬ tel mit abgestimmter Wirkung möglich, d.h. es lassen sich gleichzeitig mehrere Löscheffekte erreichen, wie Trennen, Energieentzug, Inhibitionseffekte, mechanische Wirkungen u. dgl., wobei diese Effekte erzielt werden, ohne daß der Be¬ nutzer besondere Maßnahmen treffen muß.With the invention, the targeted combination of extinguishing agents with a coordinated effect is possible, i.e. it can be achieved several extinguishing effects, such as disconnection, energy withdrawal, inhibition effects, mechanical effects and. The like. These effects are achieved without the user having to take any special measures.
Je nach Einsatzzweck kann das Löschmittel als Flüssigkeit, Schaum, Gas oder als Pulver ausgeworfen werden; je nach Ag¬ gregatzustand des Löschmittels kann ein Löschmittel selbst in unterschiedlichen Arten ausgedüst werden.Depending on the application, the extinguishing agent can be ejected as a liquid, foam, gas or powder; Depending on the aggregate state of the extinguishing agent, an extinguishing agent can itself be sprayed in different ways.
Hierzu sieht die Erfindung Ausgestaltungen in den Unteran¬ sprüchen vor. So kann das Löschmittel in einer asymmetrischen Verteilung aus der Löschmitteldüse ausgeworfen werden. Dabei kann es zweckmäßig sein, ggf. das Löschmittel wenigstens mit einem konzentrierten Eindringstrahl und einem gefächerten Flach¬ strahl auszuwerfen.To this end, the invention provides refinements in the subclaims. The extinguishing agent can be ejected from the extinguishing agent nozzle in an asymmetrical distribution. It may be expedient to eject the extinguishing agent at least with a concentrated penetrating jet and a fanned flat jet.
Es kann auch so verfahren werden, daß neben einem Eindring¬ strahl ein oszillierender Punktstrahl ausgeworfen wird und/ oder ein Löschmittelnebel.The procedure can also be such that, in addition to an penetrating jet, an oscillating point jet is ejected and / or an extinguishing agent mist.
Eine besondere Verfahrensweise besteht darin, daß als Lösch¬ mittel Inertgase, eine Löschflüssigkeit, wie beispielsweise Wasser, Schäume oder Löschmittelpulver insbesondere zur Er¬ zeugung einer Löschmitteleindringzone, einer Kühlzone und einer Trennzone am Brandherd eingesetzt werden.A special procedure consists in using inert gases, an extinguishing liquid such as water, foams or powder for extinguishing agents, in particular to produce an extinguishing agent penetration zone, a cooling zone and a separation zone at the source of the fire.
Ausgestaltungen der Vorrichtung sind erfindungsgemäß dadurch gegeben, daß der Düsenkopf mit einem einen Eindringstrahl erzeugenden Düsenmund und einem weiteren Düsenmund ausgerü¬ stet ist, wobei der weitere Düsenmund zur Erzeugung eines oszillierenden Punktstrahles, eines Flachstrahles oder eines Löschmittelnebels erfindungsgemäß ausgebildet sein kann. Selbstverständlich kann in einem Düsenmund auch nicht nur die Alternative zwischen zwei derartigen, unterschiedliche Löschmittelstrahle erzeugende Düsen vorgesehen sein, sondern mehrere, wie beispielsweise Flachstrahl, Punktstrahl und Ne- bei als oszillierender Punktstrahl oder oszillierender Ne¬ belstrahl, um nur einige Beispiele zu nennen.Embodiments of the device are provided in accordance with the invention in that the nozzle head is equipped with a nozzle mouth which generates an penetrating jet and a further nozzle mouth, the further nozzle mouth being able to be designed in accordance with the invention to generate an oscillating point jet, a flat jet or an extinguishing agent mist. Of course, not only the alternative between two such nozzles producing different extinguishing agent jets can be provided in one nozzle mouth, but several, such as, for example, flat jet, point jet and ne as an oscillating point beam or oscillating fog beam, to name just a few examples.
Die Gestaltung kann dabei beispielsweise so getroffen sein, daß der Düsenmund für den Eindringstrahl und der Düsenmund für den Flachstrahl räumlich voneinander getrennt oder in¬ einander übergehend am Düsenkopf ausgebildet sind.The design can be such that the nozzle mouth for the penetrating jet and the nozzle mouth for the flat jet are spatially separated from one another or are merged into one another on the nozzle head.
Für eine gestalterisch besonders einfache Verwirklichung ist nach der Erfindung vorgesehen, daß der Düsenkopf mit einem Einschraubgewinde zum Einschrauben unterschiedlich gestalte¬ ter Düsenmünder versehen ist, wobei auch vorgesehen sein kann, daß der Düsenkopf als Nachrüstteil aus Kunststoff aus¬ gebildet ist.For a particularly simple implementation, the invention provides that the nozzle head is provided with a screw thread for screwing in differently designed nozzle mouths, it also being possible for the nozzle head to be designed as a retrofit part made of plastic.
