Description

Die Neuerung betrifft eine mobile Feuerlöscheinrichtung zum Versprühen von pulverförmigem Löschmittel durch ein Druckgas entsprechend dem Oberbegriff des ersten Schutzanspruches.The innovation relates to a mobile fire-extinguishing device for spraying pulverulent extinguishing agent by a compressed gas according to the preamble of the first protection claim.

Die Neuerung ist geeignet für mobile Feuerlöscheinrichtungen, bei denen ein pulverförmiges Löschmittel durch ein Druckgas aus einem Druckbehälter auf den Brandherd transportiert wird.The innovation is suitable for mobile fire-fighting equipment, in which a powdered extinguishing agent is transported by a compressed gas from a pressure vessel to the source of fire.

Aus DE 101 34 610 C1 ist eine Feuerlöschanlage mit zumindest einem unter Druck stehenden Löschmittel, insbesondere Stickstoffgas aufnehmenden Druckbehälter mit einem Abgabeventil bekannt. Derartige Feuerlöschanlagen weisen in der Regel einen ausgesprochen komplizierten Mechanismus auf, um Druckverluste zu vermeiden und eine schnelle Abgabe des Feuerlöschmittels zu ermöglichen.Out DE 101 34 610 C1 is a fire extinguishing system with at least one pressurized extinguishing agent, in particular nitrogen gas receiving pressure vessel with a dispensing valve known. Such fire extinguishing systems usually have a very complicated mechanism to avoid pressure losses and to allow rapid release of the fire extinguishing agent.

Aus DE-OS 2 201 606 ist eine Feuerlöscheinrichtung zum Bekämpfen von Großbränden, insbesondere Flugzeugbränden, bekannt, deren Löschmittel sich in einem Löschmittelbehälter befindet und aus diesem durch ein schwenkbares Strahlrohr mittels Feuerlöschaggregaten, Bestrahl- oder Kreiselpumpen oder Gasgenerator ausgestoßen wird. Das Löschmittel wird mittels eines oder mehrerer pyrotechnischer Treibsätze oder Raketentriebwerke beschleunigt. Der Übergang zwischen dem Löschmittelbehälter und dem Strahlrohr ist mittels einer Berstscheibe verschlossen.Out DE-OS 2 201 606 is a fire extinguishing device for controlling large fires, especially aircraft fires, known, the extinguishing agent is located in an extinguishing agent tank and is ejected from this by a pivotable jet pipe by means of fire extinguishing units, jet or centrifugal pumps or gas generator. The extinguishing agent is accelerated by means of one or more pyrotechnic propellant charges or rocket engines. The transition between the extinguishing agent tank and the jet pipe is closed by means of a rupture disk.

In DE-OS 25 32 562 ist ein Feuerlöscher mit einem Löschmittelbehälter und mit einem in dem Löschmittelbehälter endseitig eingesetzten Armaturengehäuse beschrieben, an dem im Inneren des Löschmittelbehälters eine Hochdruckflasche und ein Gasrohr für das Treibgas sowie ein Steigrohr für das bei einem Löschvorgang angetriebene Löschmittel befestigt ist, wobei das Armaturengehäuse außen mit einem Löschschlauch sowie mit einem Traggriff und einem schwenkbar gelagerten, durch eine Sicherung vor unbeabsichtigtem Auslösen geschützten Auslösehebel versehen ist, wobei eine den Verschluß der Hochdruckgasflasche zerstörende Auslösespindel vorgesehen ist und ein den Gasraum abdichtendes Trennelement.In DE-OS 25 32 562 a fire extinguisher with an extinguishing agent container and with a valve body used in the extinguishing agent container housing described at the inside of the extinguishing agent container, a high pressure bottle and a gas pipe for the propellant gas and a riser for the extinguishing agent driven in an extinguishing process is fixed, the valve body outside with a Extinguishing hose and is provided with a carrying handle and a pivotally mounted, protected by a fuse from unintentional triggering release lever, wherein a closure of the high-pressure gas cylinder destructive trigger spindle is provided and a gas chamber sealing separator.

All diese Lösungen kombinieren komplizierte Auslösemechanismen mit entsprechenden Dichtungen. Das ist materialaufwendig und teuer.All of these solutions combine complicated triggering mechanisms with appropriate seals. This is material-consuming and expensive.

Aus DE 26 35 076 A1 ist eine mobile Feuerlöscheinrichtung zum Versprühen von pulverförmigem Löschmittel durch ein Druckgas aus einem Druckbehälter bekannt, der das Druckgas und das pulverförmige Löschmittel enthält, wobei am Behälter mindestens ein Ventil zwischen dem Druckbehälter und dem Angriffsmittel angeordnet ist und zwischen dem Sprengmittel mit Berstscheibe und der Anschlußleitung für das Angriffsmittel ein Ventil angeordnet ist und das Sprengmittel mit Öffnung des Ventils ausgelöst wird.Out DE 26 35 076 A1 is a mobile fire extinguishing device for spraying powdered extinguishing agent by a compressed gas from a pressure vessel containing the compressed gas and the powdered extinguishing agent, wherein the container at least one valve between the pressure vessel and the engaging means is disposed and between the explosive device with rupture disc and the connection line for the attack means a valve is arranged and the disintegrant is triggered with the opening of the valve.

Nachteilig an dieser Lösung ist, daß die Sprengwirkung des Sprengmittels gegen den Inhalt des Druckbehälters wirkt und es zu einem unerwünschten Druckaufbau im Behälter kommt. Es ist daher Aufgabe der Erfindung, eine mobile Feuerlöscheinrichtung zum Versprühen von pulverförmigem Löschmittel durch ein Druckgas zu schaffen, bei dem einem unerwünschten Druckaufbau im Behälter zuvorgekommen wird.A disadvantage of this solution is that the explosive effect of the disintegrant acts against the contents of the pressure vessel and there is an undesirable pressure build-up in the container. It is therefore an object of the invention to provide a mobile fire-extinguishing device for spraying powdered extinguishing agent by a pressurized gas, which is preceded by an undesirable pressure build-up in the container.

Diese Aufgabe wird durch eine mobile Feuerlöscheinrichtung nach den Merkmalen des ersten Anspruches gelöst.This object is achieved by a mobile fire-extinguishing device according to the features of the first claim.

Unteransprüche geben vorteilhafte Ausgestaltungen der Neuerung wieder.Subclaims give advantageous embodiments of the innovation again.

Die gefundene Lösung sieht vor, daß an einem Druckbehälter, der das Druckgas und das pulverförmige Löschmittel enthält, ein Ventil angeordnet ist. Dieses Ventil kann vorteilhafterweise ein Kugelventil darstellen und muß nicht höchsten Anforderungen an ein dicht schließendes Ventil entsprechen. Nach dem Ventil in Richtung auf die Anschlußleitung, die zum Angriffsmittel führen, ist eine Berstscheibe angeordnet, durch die Dichtheit des Druckbehälters erreicht wird. Vor der Berstscheibe und nach dem Ventil ist ein Sprengmittel, beispielsweise ein elektrischer Piezozünder, angeordnet, der im Falle eines Löschmitteleinsatzes und bei Öffnen des Ventils ausgelöst wird. Nach der Berstscheibe kann eine Verzweigung für mehrere Anschlußleitungen angeordnet sein. Für das Öffnen des Ventils und das Auslösen des Sprengmittels kann ein gemeinsamer Auslösemechanismus angeordnet sein. Das kann ein Druckknopf sein, bei dessen Druck das Ventil auf elektrischer Basis geöffnet wird und der Piezozünder in Aktion tritt, das kann aber auch ein Hebel sein, der dann betätigt wird, wenn das Angriffsmittel auf den Brandherd gerichtet ist, so daß mit der Betätigung des Hebels das Ventil geöffnet wird und ein Strom den Piezozünder aktiviert.The solution found provides that at a pressure vessel containing the compressed gas and the powdery extinguishing agent, a valve is arranged. This valve may advantageously constitute a ball valve and does not have to meet the highest requirements for a tight-fitting valve. After the valve in the direction of the connecting line leading to the attack means, a rupture disc is arranged, is achieved by the tightness of the pressure vessel. Before the rupture disk and after the valve, a disintegrating means, for example an electric piezoelectric igniter, arranged, which is triggered in the case of an extinguishing agent and when opening the valve. After the rupture disk, a branch can be arranged for a plurality of connecting lines. For the opening of the valve and the triggering of the explosive means, a common triggering mechanism may be arranged. This may be a push button, the pressure on the valve is opened on an electrical basis and the piezoelectric igniter comes into action, but this can also be a lever which is then actuated when the attacking means is directed to the fire, so that with the operation of the lever the valve is opened and a current activates the piezoelectric igniter.

Sprengmittel und Ventil sind bei der vorliegenden Lösung gleichzeitig zu betätigen, damit die Sprengwirkung nicht gegen den Inhalt des Druckbehälters wirkt.Explosive means and valve are to be operated simultaneously in the present solution, so that the explosive effect does not act against the contents of the pressure vessel.

Es ist vorteilhaft, wenn der Druck vor dem Ventil ca. 10 bar niedriger ist als der Berstdruck der Berstscheibe. Vorteilhaft ist es, die Berstscheibe für einen Druck von 40 bar auszulegen.It is advantageous if the pressure in front of the valve is about 10 bar lower than the bursting pressure of the rupture disk. It is advantageous to design the rupture disk for a pressure of 40 bar.

Im Folgenden wird die Neuerung an einem Ausführungsbeispiel mit zwei Figuren erläutert.In the following, the innovation of an embodiment with two figures will be explained.

Die Figur 1 zeigt die schematische Darstellung einer mobilen Feuerlöscheinrichtung mit einer Verzweigung und mehreren Anschlußleitungen, während die Figur 2 eine Feuerlöscheinrichtung mit nur einer Anschlußleitung zeigt.The FIG. 1 shows the schematic representation of a mobile fire extinguisher with a branch and multiple leads, while the FIG. 2 a fire extinguisher with only one connection line shows.

Die Figur 1 zeigt den Druckbehälter 1, von dem eine Leitung 2 zum Kugelventil 3 führt, welches mit einem Auslösemechanismus 7, einem Druckknopf, verbunden ist, der gleichzeitig einen Piezozünder 4 mit dem Sprengmittel in Betrieb setzt, der vor einer Berstscheibe 5 angeordnet ist. Die Berstscheibe 5 ist für einen Druck von 40 bar ausgelegt und verhindert, daß das unter Druck stehende Löschpulver, welches vom Löschgas, im vorliegenden Fall N2, über das Kugelventil 3 bei Undichtheit des selben abfallen kann. Damit ist gewährleistet, daß der Druck des Stickstoffes im Löschmittelbehälter immer konstant ist. Im vorliegenden Fall beträgt dieser Druck 30 bar. Im Fall eines Brandes wird der Auslösemechanismus 6 betätigt, worauf die Explosion des Sprengmittels 4 zur Zerstörung der Berstscheibe 5 führt und gleichzeitig das Kugelventil geöffnet wird, so daß das Löschmittel in Richtung auf die Anschlußleitung 6 entweichen und den Brand löschen kann.The FIG. 1 shows the pressure vessel 1, from which a line 2 leads to the ball valve 3, which is connected to a trigger mechanism 7, a push button, the simultaneously sets a piezoelectric igniter 4 with the disintegrating means in operation, which is arranged in front of a rupture disk 5. The rupture disk 5 is designed for a pressure of 40 bar and prevents the pressurized extinguishing powder, which can drop from the quenching gas, in the present case N 2 , via the ball valve 3 in case of leakage of the same. This ensures that the pressure of the nitrogen in the extinguishing agent tank is always constant. In the present case, this pressure is 30 bar. In the event of a fire, the trigger mechanism 6 is operated, whereupon the explosion of the explosive means 4 leads to the destruction of the rupture disk 5 and at the same time the ball valve is opened, so that the extinguishing agent in the direction of the connecting line 6 escape and can extinguish the fire.

Die Feuerlöscheinrichtung hat den Vorteil, daß der Druck des Löschgases im Löschmittelbehälter 1 trotz eines wenig gut verschließenden Ventils 3 so lange konstant bleibt, bis der Auslösemechanismus betätigt wird. Damit besteht die Möglichkeit, auch wenig komplizierte und druckdichte Ventile 3 zum Verschließen des Löschmittelbehälters 1 zu verwenden.The fire extinguishing device has the advantage that the pressure of the extinguishing gas in the extinguishing agent tank 1, despite a little good closing valve 3 remains constant until the trigger mechanism is actuated. This makes it possible to use even less complicated and pressure-tight valves 3 for closing the extinguishing agent container 1.
