Description

Die Erfindung betrifft eine Vorrichtung zur Brandbekämpfung mit einer über eine Rohrleitung mit einer Löschfluidversorgung verbundenen Löschdüse und mit einer Alarmeinrichtung, die mit Beginn eines Löschvorgangs ein Warnsignal abgibt. Solche Vorrichtungen werden beispielsweise stationär in Gebäuden oder anderen vor Bränden zu schützenden Einrichtungen installiert. Dabei sind in der Regel Einrichtungen vorgesehen, welche bei Entstehung eines Brandes selbsttätig das Ausbringen von Löschfluid auslösen.The invention relates to a device for Firefighting with a pipeline with a Extinguishing fluid supply connected extinguishing nozzle and with a Alarm device that at the beginning of a delete process Gives a warning signal. Such devices will for example, stationary in buildings or others Fires installed to protect facilities. there facilities are usually provided, which at The occurrence of a fire automatically starts Trigger extinguishing fluid.

Die Alarmeinrichtungen geben in vielen Fällen mit Beginn des Löschvorgangs eine über eine größere Entfernung wahrnehmbare Warnung in Form eines akustischen Signals ab. Auf diese Weise ist sichergestellt, dass auch der in einem unbeobachteten Bereich beginnende Löschvorgang und folglich auch der Brand selbst von in der Umgebung des betroffenen Bereichs sich aufhaltenden Personen wahrgenommen wird.The alarm devices give in many cases from the beginning of the deletion process over a greater distance perceptible warning in the form of an acoustic signal from. In this way it is ensured that the in an unobserved area, and consequently also the fire itself in the vicinity of the affected area is perceived.

Zu diesem Zweck sind bei bekannten Sprinkleranlagen sogenannte "Sprinkler-Glocken" vorgesehen, die nach Art einer Turbine von dem im Brandfall durch die Rohrleitung strömenden Wasser angetrieben werden. Bei Brandbekämpfungsvorrichtungen, bei denen gasförmige Medien als Löschfluid eingesetzt werden, ist es darüber hinaus bekannt, einen Teil des Gases durch eine pneumatisch arbeitende Sirene zu leiten.For this purpose are known sprinkler systems So-called "sprinkler bells" provided, which according to Art a turbine of which in the event of fire through the pipeline flowing water are driven. at Firefighting devices where gaseous Media used as the extinguishing fluid is about it also known some of the gas through a direct pneumatic siren.

Der Nachteil der bekannten Alarmsysteme besteht bei Sprinklersystemen, bei denen die Alarmeinrichtung von dem flüssigen Löschmedium hydraulisch angetrieben wird, darin, dass eine aus der jeweiligen Rohrleitung herausführende Antriebswelle vorhanden sein muss. Im Bereich dieser Drehdurchführung kann es zu Leckagen kommen. Zusätzlich behindert der Antriebsmechanismus die Strömung des Löschfluids in der Rohrleitung. Bei Löschvorrichtungen, bei denen ein Teil des gasförmigen Löschfluids zum Antrieb der Alarmeinrichtung abgezweigt wird, kann es ebenfalls zu Undichtheiten kommen. Besonders groß ist die Gefahr der Entstehung von Leckagen bei Systemen, die mit hohen Drücken arbeiten. Solch hohe Drücke werden insbesondere dann benötigt, wenn ein flüssiges Löschfluid oder ein Gemisch aus flüssigen und gasförmigen Löschmedien von den Löschdüsen zu einem Löschnebel zerstäubt wird. Mit derartigen Löschnebeln lässt sich bei geringem Bedarf an Löschmittel ein Brand besonders wirkungsvoll bekämpfen.The disadvantage of the known alarm systems is Sprinkler systems in which the alarm device by the liquid extinguishing medium is hydraulically driven, in that one from the respective pipeline leading drive shaft must be present. in the Leakage may occur in the area of this rotating union come. In addition, the drive mechanism hampers the Flow of the extinguishing fluid in the pipeline. at Extinguishing devices in which part of the gaseous Extinguishing fluids branched to drive the alarm device leaks can also occur. The risk of leakage is particularly great for systems that work with high pressures. Such high Pressures are particularly needed when a liquid extinguishing fluid or a mixture of liquid and gaseous extinguishing media from the extinguishing nozzles to one Extinguishing mist is atomized. With such extinguishing mists a fire can be started if the extinguishing agent is low fight particularly effectively.

Aus der deutschen Offenlegungsschrift DE 195 22 495 A1 ist eine Sprinkleranlage mit einer akustischen Alarmeinrichtung bekannt. Bei dieser Sprinkleranlage wird ein Druckschalter vorgeschlagen, durch den im Ansprechfall ein elektro-akustische Signalgeber zugeschaltet wird. Der Druckschalter ist in einem Schaltkreis geschaltet, der einen elektro-akustischen Signalgeber enthält. Wird der Druckschalter ausgelöst, so wird der Schaltkreis geschlossen und der elektro-akustische Signalgeber erzeugt ein Signal.From German published application DE 195 22 495 A1 is a sprinkler system with an acoustic Alarm device known. With this sprinkler system proposed a pressure switch through which in Response an electro-acoustic signal transmitter is switched on. The pressure switch is in one Switched circuit, which is an electro-acoustic Signal generator contains. If the pressure switch is triggered, so the circuit is closed and the electro-acoustic Signal generator generates a signal.

Die Aufgabe der Erfindung besteht darin, eine Vorrichtung zur Brandbekämpfung zu schaffen, bei der einerseits die Gefahr der Entstehung von Leckagen vermindert und andererseits eine wirkungsvolle Alarmierung der Umgebung bei Beginn des Löschvorgangs gewährleistet ist.The object of the invention is a device to create fire fighting, on the one hand the Reduced risk of leakage and on the other hand, an effective alarming of the environment guaranteed at the start of the deletion process.

Diese Aufgabe wird durch eine Vorrichtung zur Brandbekämpfung mit einem über eine Rohrleitung mit einer Löschfluidversorgung verbundenen Düsenkopf und mit einer Alarmeinrichtung, die mit Beginn eines Löschvorgangs ein Warnsignal abgibt, gelöst, bei der die Alarmeinrichtung eine druckbetätigbare, an die Rohrleitung angeschlossene Schalteinrichtung umfasst, welche bei einer Erhöhung des in der Rohrleitung herrschenden Drucks das warnsignal auslöst, derart, dass die Schalteinrichtung eine von gespeicherter Druckenergie angetriebene Signalerzeugungseinrichtung betätigt.This task is accomplished by a device for Firefighting with a pipeline with a Extinguishing fluid supply connected nozzle head and with a Alarm device that at the beginning of a delete process Issues warning signal, resolved at the alarm device a pressure operated, connected to the pipeline Switching device which, when the the warning signal in the pipeline triggers such that the switching device one of stored pressure energy powered Signal generating device actuated.

Gemäß der Erfindung treibt das Löschfluid die Alarmeinrichtung nicht mehr an, sondern es wird eine mit der Rohrleitung in Verbindung stehende, druckempfindliche Schalteinrichtung eingesetzt, die den durch die Erhöhung des Drucks in der Rohrleitung charakterisierten Beginn des Löschvorgangs erkennt und das warnsignal auslöst. Die beim Stand der Technik vorhandene Verbindung zwischen der Rohrleitung und der Umgebung über die für die Drehdurchführung des hydraulischen Antriebs der Alarmeinrichtung oder das Abströmen von Löschgas erforderlichen Rohröffnungen wird bei erfindungsgemäß ausgebildeten Vorrichtungen nicht mehr benötigt. Daher ist bei erfindungsgemäßen Vorrichtungen auch die Gefahr der Entstehung von Undichtigkeiten auf ein Minimum reduziert.According to the invention, the extinguishing fluid drives the Alarm device no longer on, but it becomes one with pipeline related, pressure sensitive Switching device used by the increase of the pressure in the pipeline characterized the beginning recognizes the deletion process and triggers the warning signal. The in the prior art existing connection between the Pipeline and the environment beyond that for the Hydraulic drive of the Alarm device or the discharge of extinguishing gas required pipe openings is in accordance with the invention trained devices are no longer required. Therefore is also the danger with devices according to the invention the occurrence of leaks to a minimum reduced.

Die erfindungsgemäße Ausgestaltung einer Brandlöschvorrichtung lässt sich sowohl anwenden bei Systemen, bei denen die Rohrleitung im Ruhezustand der Vorrichtung mit unter einem Ruhedruck stehenden Löschfluid gefüllt ist, als auch bei solchen Systemen, bei denen die Rohrleitung im Ruhezustand der Vorrichtung trocken ist. Ebenso kann die Rohrleitung im Ruhezustand mit einem gasförmigen Medium, wie Luft oder N2, beaufschlagt sein, wobei diese Medien zur Verbesserung der Reaktionszeiten unter einem Ruhedruck stehend vorgespannt sein können. Bei allen Systemen dieser Art stellt die mit dem Beginn des Löschvorgangs einhergehende Erhöhung des Drucks in der Rohrleitung ein eindeutiges Kriterium für das Auslösen des Warnsignals dar.The design of a fire extinguishing device according to the invention can be used both in systems in which the pipeline is filled with extinguishing fluid under a quiescent pressure as well as in systems in which the pipeline is dry in the quiescent state of the device. Likewise, the pipeline can be charged with a gaseous medium, such as air or N 2 , in the idle state, whereby these media can be biased under a static pressure to improve the reaction times. In all systems of this type, the increase in pressure in the pipeline associated with the start of the extinguishing process represents a clear criterion for triggering the warning signal.

Die Alarmeinrichtung kann ein optisches Warnsignal oder ein akustisches Warnsignal abgeben. Selbstverständlich können diese Signalformen auch kombiniert werden. Dabei läßt sich das im Rohrnetz strömende Löschfluid dazu nutzen, einen Klangkörper oder eine Membran in Schwingungen zu versetzen, ohne jedoch das Rohrsystem zu verlassen.The alarm device can be an optical warning signal or give an acoustic warning signal. Of course these waveforms can also be combined. there the extinguishing fluid flowing in the pipe network can be added use a sound body or a membrane in To vibrate, but without the pipe system leave.

Eine für die praktische Umsetzung besonders vorteilhafte Variante der Erfindung ist dadurch gekennzeichnet, daß die Schalteinrichtung ein an einer elastischen Abstützung abgestüztes Druckaufnahmelement aufweist und daß sich das Druckaufnahmeelement bei Erhöhung des in der Rohrleitung herrschenden Drucks gegen die Kraft der elastischen Abstützung aus seiner Ruhestellung in seine Auslösestellung bewegt. Mit einem solchen Schaltelement lassen sich hydraulisch oder pneumatisch betriebene Alarmeinrichtungen problemlos auslösen. Dabei ist die elastische Abstützung vorzugweise eine Feder. Mit einem derartigen elastischen Mittel lassen sich auch auf engem Raum auf einfache Weise Kräfte erzeugen, die ausreichen, um das Schaltelement im Ruhezustand sicher in der Ruhestellung zu halten.A particularly advantageous one for practical implementation Variant of the invention is characterized in that the switching device on an elastic support has supported pressure recording element and that the Pressure absorption element when increasing in the pipeline prevailing pressure against the force of the elastic Support from its rest position into its Release position moved. With such a switching element can be hydraulically or pneumatically operated Trigger alarm devices easily. Here is the elastic support preferably a spring. With a Such elastic means can also be narrow Space easily generate forces sufficient around the switching element safely in the idle state To hold at rest.

Eine weitere hinsichtlich der praktischen Anwendung besonders günstige Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß die Schalteinrichtung eine von gespeicherter Druckenergie angetriebene Signalerzeugungseinrichtung betätigt. Eine solche Signalerzeugungseinrichtung ist unabhängig von extern zuzuführenden Energieversorgungen und kann als solche problemlos an beliebigen Stellen der Rohrleitung angeschlossen werden. Besonders günstig ist es in diesem Zusammenhang, wenn die Schalteinrichtung bei Erhöhung des Drucks einen Druckspeicher öffnet, in dem das die Signalerzeugungseinrichtung antreibende Medium gespeichert ist. Dieser von der Löschfluidversorgung unabhängige Druckspeicher versorgt die Alarmeinrichtung mit der für die Abgabe des Warnsignals erforderlichen Energie, so daß die Alarmeinrichtung mit dem Druckelement und dem Druckspeicher ein gegenüber der Umgebung völlig abgeschlossenes System bildet. Dies läßt sich insbesondere dann auf einfache Weise verwirklichen, wenn der Druckspeicher im Ruhezustand mit einem Deckel versehen ist, den das Druckelement im Zuge seiner Bewegung aus der Ruhe- in die Auslösestellung durchsticht. Dieser Deckel ist vorzugsweise in Form einer erst bei einem vorbestimmten Druck brechenden Berstscheibe ausgebildet. Auf diese Weise kann leicht sichergestellt werden, daß die Alarmeinrichtung nicht durch eine in Folge eines unbeabsichtigten, unterhalb eines bestimmten Auslösedruck bleibenden Druckstoßes in der Rohrleitung hervorgerufenen Bewegung des Druckelements ausgelöst wird.Another in terms of practical application is particularly favorable embodiment of the invention characterized in that the switching device a powered by stored pressure energy Signal generating device actuated. Such Signal generation device is independent of external power supplies to be supplied and as such easily at any point on the pipeline be connected. It is particularly cheap in this Connection when the switching device when increasing the Pressure opens a pressure accumulator in which the Signal generating device driving medium is saved. This from the extinguishing fluid supply The alarm device is supplied by independent pressure accumulators with the one required to emit the warning signal Energy so that the alarm device with the pressure element and the accumulator completely compared to the environment closed system forms. This can be done especially in a simple way if the pressure accumulator in the idle state with a lid is provided, the pressure element in the course of its Movement from the rest to the release position punctures. This lid is preferably in the form of a only breaking at a predetermined pressure Rupture disc formed. That way it can be easy ensure that the alarm device is not due to an inadvertent, below of a certain trigger pressure lasting pressure surge in the movement of the pipeline Pressure element is triggered.

Eine weitere, das Vorhandensein einer gespeicherten, im Fall der Druckerhöhung aus dem jeweiligen Druckspeicher freigesetzten Druckenergie voraussetzende vorteilhafte Variante der Erfindung ist dadurch gekennzeichnet, daß das bei geöffnetem Druckspeicher ausströmende Medium eine Einrichtung zur Erzeugung von elektrischer Energie antreibt. Eine solche hydraulisch oder pneumatisch angetriebene Einrichtung liefert dann als Generator die elektrische Energie für den Betrieb einer elektrisch betriebenen Signaleinrichtung. Auf diese Weise können die Vorzüge elektrisch betriebener Warneinrichtungen, wie beispielsweise die einfache Erzeugung von Lichtsignalen oder die Ausgabe bestimmter elektrisch erzeugter Töne, genutzt werden, ohne daß dazu eine störanfällige, aufwendige Verkabelung gezogen werden müßte.Another, the presence of a stored in Case of pressure increase from the respective pressure accumulator Released advantageous pressure energy Variant of the invention is characterized in that the medium flowing out when the pressure accumulator is open Device for generating electrical energy drives. Such a hydraulic or pneumatic driven device then delivers as a generator electrical energy for the operation of an electrical operated signaling device. That way they can Advantages of electrically operated warning devices, such as for example the simple generation of light signals or the output of certain electrically generated tones, be used without a fault-prone, elaborate cabling would have to be pulled.

Besonders günstig läßt sich die Erfindung bei solchen Vorrichtungen einsetzen, bei denen im Brandfall Löschfluid mit einem über 10 bar, vorzugsweise über 70 bar liegenden Hochdruck durch die Rohrleitung strömt. Dabei ist die Eignung der Erfindung unabhängig davon, ob das Löschfluid mittels gespeicherter Druckenergie oder von Pumpen zur Düse gefördert wird, wobei die Erfindung sich aufgrund des Umstandes, daß für ihre Funktion keine externe elektrische Energie benötigt wird, besonders vorteilhaft in Verbindung mit Löschsystemen einsetzen läßt, bei denen das Löschfluid unter Druck in Druckspeichern für den Fall eines Brandes bereitsteht.The invention can be used particularly cheaply with such Use devices in the event of fire Extinguishing fluid with an over 10 bar, preferably over 70 bar high pressure flows through the pipeline. The suitability of the invention is independent of whether the extinguishing fluid by means of stored pressure energy or is promoted by pumps to the nozzle, the invention due to the fact that none for their function external electrical energy is needed, especially use advantageously in connection with extinguishing systems can, in which the extinguishing fluid under pressure in Pressure accumulators are available in the event of a fire.

the device of FIG. 1 during an erasing process.

Die Vorrichtung 1 umfaßt eine aus einem flexiblen, schlauchartigen oder starren Material gefertigte Rohrleitung 2, die einen Druckspeicher 3 mit einem Düsenkopf 4 verbindet. Im von elektrischer Energie unabhängigem Druckspeicher 3 ist als Löschfluid L beispielsweise Wasser gespeichert. Alternativ kann die Vorrichtung 1 im Brandfall auch über eine nicht dargestellte Pumpe mit Löschwasser versorgt werden.The device 1 comprises a flexible, tubular or rigid material Pipeline 2, the pressure accumulator 3 with a Nozzle head 4 connects. Im of electrical energy independent pressure accumulator 3 is as extinguishing fluid L. for example water is stored. Alternatively, the Device 1 in the event of a fire also not shown pump can be supplied with extinguishing water.

Der Düsenkopf 4 ist mit Löschdüsen 5 bestückt, die während eines Löschvorgangs das Löschfluid in einen fein verteilten Löschnebel zerstäuben.The nozzle head 4 is equipped with extinguishing nozzles 5 which during an extinguishing process the extinguishing fluid into a fine atomize the distributed extinguishing mist.

An die Rohrleitung 2 ist benachbart zum Düsenkopf 4 eine Alarmeinrichtung 5 angeschlossen. Die Alarmeinrichtung 5 umfaßt ein Gehäuse 6, dessen Innenraum über eine Verbindungsöffnung 7 mit dem Innenraum der Rohrleitung 2 verbunden ist. In dem Gehäuse 6 ist als Druckelement ein Kolben 8 geführt, der auf seiner der Verbindungsöffnung 7 zugewandten Seite eine verbreiterte Druckplatte 9 aufweist. Mit ihren Seitenflächen liegt die Druckplatte 9 dicht an den seitlichen Wänden des Gehäuses 6 an. An die Druckplatte 9 ist auf ihrer von der Verbindungsöffnung 7 abgewandten Seite ein stiftförmiges Führungselement 10 des Kolbens 8 angeformt, der durch eine Führungsöffnung 11 am Boden des Gehäuses 6 geführt ist. Gleichzeitig ist der Kolben 8 über eine koaxial zu dem Führungselement 10 angeordnete Spiralfeder 12 elastisch am Boden des Gehäuses 6 abgestüzt. An seinem freien, aus der Führungsöffnung 11 herausragenden Ende trägt das Führungselement 10 eine Spitze 13. On the pipeline 2 is adjacent to the nozzle head 4 Alarm device 5 connected. The alarm device 5 comprises a housing 6, the interior of which Connection opening 7 with the interior of the pipeline 2 connected is. In the housing 6 is a pressure element Piston 8 out, the on its connecting opening 7th facing side a widened pressure plate 9 having. The pressure plate 9 lies with its side faces close to the side walls of the housing 6. To the Pressure plate 9 is on its from the connection opening 7 facing away from a pin-shaped guide element 10 of the piston 8 formed through a guide opening 11 is guided on the bottom of the housing 6. At the same time the piston 8 via a coaxial to the guide element 10 arranged coil spring 12 elastic at the bottom of the Supported housing 6. At its free, from the Guide opening 11 protruding end carries that Guide element 10 has a tip 13.

Über eine dicht mit dem Gehäuse 6 verbundene, die Führungsöffnung 11 umgebende Hülse 14 ist gegenüberliegend zur Führungsöffnung 11 und mit einem bestimmten Abstand zu dieser eine Druckflasche 15 befestigt, in der ein gasförmiges Medium, beispielsweise Luft, unter Druck gespeichert ist. Die Hülse 14 hält den Kopf der Druckflasche 15 ebenfalls dicht umschlossen. Die der Führungsöffnung 11 gegenüberliegende Öffnung der Druckflasche 14 ist im Ruhezustand mittels einer Berstscheibe 16 dicht verschlossen.About a tightly connected to the housing 6, the Guide opening 11 surrounding sleeve 14 opposite to the guide opening 11 and with a certain distance from this a pressure bottle 15th attached in which a gaseous medium, for example Air that is stored under pressure. The sleeve 14 holds the Head of the pressure bottle 15 also tightly enclosed. The the opening of the guide opening opposite the Pressure bottle 14 is at rest by means of a Rupture disc 16 tightly closed.

Über eine Schlauchverbindung 17 ist eine pneumatisch arbeitende Sirene 18 mit dem Innenraum der Hülse 14 verbunden.A hose connection 17 is pneumatic working siren 18 with the interior of the sleeve 14 connected.

Im Ruhezustand kann die Rohrleitung 2 mit unter einem Ruhedruck stehenden Löschfluid gefüllt sein. Dies hat den Vorteil, daß sich durch einen Druckabfall in der Rohrleitung 2 bemerkbar machende Leckagen schnell erkannt werden können. Genauso kann die Rohrleitung 2 im Ruhezustand jedoch auch trocken sein oder mit einem druckbeaufschlagten gasförmigen Medium, wie Druckluft oder Stickstoff, vorgespannt sein.In the idle state, the pipeline 2 can be under one Extinguishing fluid at rest pressure must be filled. This has the Advantage that a pressure drop in the Pipeline 2 quickly detectable leaks can be. In the same way, the pipeline 2 in the However, hibernation can also be dry or with a pressurized gaseous medium, such as compressed air or nitrogen.

Bei Entstehung eines Brandes wird beispielsweise durch einen hier nicht gezeigten, am Düsenkopf 4 angeordneten Brandwächter die Ausbringung von Löschfluid ausgelöst. Die Rohrleitung 2 wird daraufhin aus dem Druckspeicher 3 mit unter erhöhtem Druck stehenden Löschfluid L gespeist (Fig. 2). Aufgrund der damit einhergehenden Erhöhung des Drucks in der Rohrleitung 2 wird der Kolben 8 gegen die Kraft der Feder 12 in Richtung der Berstscheibe 16 bewegt. Die Spitze 13 wird auf diese Weise über den im Ruhezustand zwischen ihr und der Berstscheibe 16 bestehenden Abstand bewegt bis sie auf der Berstscheibe 16 aufsitzt. Überschreitet der Druck in der Rohrleitung 2 und damit einhergehend der von der Spitze 13 auf die Berstscheibe 16 ausgeübte Druck einen bestimmten Mindestwert, so zerbricht die Berstscheibe 16 und gibt die Öffnung der Druckflasche 15 frei.If there is a fire, for example a not shown here, arranged on the nozzle head 4 Fire guard triggered the application of extinguishing fluid. The pipeline 2 is then from the pressure accumulator 3rd fed with extinguishing fluid L under increased pressure (Fig. 2). Due to the associated increase in Pressure in the pipe 2, the piston 8 against the Force of the spring 12 in the direction of the rupture disc 16 emotional. The tip 13 is in this way over the Idle state between it and the rupture disc 16 existing distance moves until it is on the rupture disc 16 sits on. If the pressure in the pipeline exceeds 2 and associated with that from the top 13 to the Rupture disc 16 exerted a certain pressure Minimum value, the rupture disk 16 breaks and gives the opening of the pressure bottle 15 freely.

Das in der Druckflasche 15 gespeicherte gasförmige Medium strömt daraufhin durch die Schlauchleitung 17 zur Sirene 18, die, angetrieben durch das gasförmige Medium, ein akustisches Warnsignal abgibt. The gaseous medium stored in the pressure bottle 15 then flows through the hose line 17 to the siren 18, driven by the gaseous medium emits an acoustic warning signal.
