Abstract

The hollow nozzle has a hollow jet nozzle (03) in which an axially movable cone shaped beam (06) is placed in jet and spray jet positions (04,05). The axially movable cone shaped beam is moved by a crank mechanism (08) alternately in rapid succession from jet to spray jet positions. A turbine valve (12) is manually opened and closed smoothly by driving crank mechanism using water turbine. An outer dial (13) is provided for adjusting positions of the spray jet manually. Crank mechanism is manually blocked in uninterrupted and continuous positions of spray jet.

Description

Die Erfindung betrifft ein Strahlrohr zur punktuellen Bekämpfung von spannungsführenden Brandherden, besonders im Außenangriff und bei Sichtbehinderung.The invention relates to a jet pipe for selective control of live fire pits, especially in outdoor attack and visual disability.

Aufgabetask

Mit der Erfindung soll eine technische Einrichtung geschaffen werde, mit der ein Brand an einem spannungsführenden Objekt mit punktuell gezielten Vollstrahlen bekämpft werden kann, ohne den Feuerwehrmannelektrisch zu gefährdenWith the invention of a technical device is created, with a fire on a live object with selectively targeted solid beams can be combated without jeopardizing the firefighter electrical

Stand der TechnikState of the art

Beim Außenangriff und bei der Bekämpfung einzelner Brandherde müssen große Wassermengen gezielt auf einen Punkt geschossen werden. Deshalb schießt die Feuerwehr in solchen Fällen einen „Vollstrahl”, der als geschlossener „Stab” aus der Spritzdüse kommt, und von der umgebenden Luft auf der Wurfparabel fließend in Klumpen und Tropfen aufgelöst wird. Ein Sprühstrahl hat andere Aufgaben. Er projiziert einen Fächer von Wassertropfen auf kurzer Entfernung, bekämpft damit den Brand flächig, aber nicht punktuell, und schützt den Feuerwehrmann.When attacking outdoors and fighting individual fires, large amounts of water have to be targeted at one point. Therefore, the fire department shoots in such cases a "full jet", which comes as a closed "rod" from the spray nozzle, and is dissolved by the surrounding air on the parable parabola flowing into lumps and drops. A spray has other tasks. He projects a fan of water droplets at a short distance, thus fighting the fire flat, but not punctually, and protects the firefighter.

Aber wenn das Brandobjekt unter elektrischer Spannung steht, dann kann ein ununterbrochener Vollstrahl eine elektrische Verbindung zwischen dem Brandobjekt und dem Strahlrohr bilden, wodurch der Feuerwehrmann gefährdet, wird, der das Strahlrohr halt. Denn der ununterbrochene Kern eines Vollstrahls kann elektrischen Strom galvanisch leiten. Ein Sprühstrahl kann das nicht.But if the fire object is under electrical tension, then an uninterrupted jet can form an electrical connection between the fire object and the jet pipe, thereby endangering the firefighter who is holding the jet pipe. Because the uninterrupted core of a full jet can conduct electricity electrically. A spray can not do that.

Die Feuerwehr darf daher in Deutschland den Brand an einem spannungsführenden Objekt nur dann mit eine ununterbrochenen Vollstrahl bekämpfen, wenn sie dabei bestimmte Abstände zwischen Objekt und Strahlrohr nicht unterschreitet. Diese Abstände sind in der DIN/VDE 0132 vorgeschrieben. Sie betreffen Photovoltaik Anlagen und Einrichtungen mit hohen und höchsten Spannungen, und richten sich nach der Höhe der vermuteten elektrischen Spannung.The fire brigade may therefore only fight the fire on a live object in Germany with an uninterrupted full jet, provided it does not go below certain distances between the object and the radiant tube. These distances are in the DIN / VDE 0132 required. They relate to photovoltaic systems and equipment with high and highest voltages, and are based on the level of the suspected electrical voltage.

Aber diese Vorschrift ist in Fachkreisen umstritten. Denn In vielen Fällen unterliegen die vorgehenden Trupps im Brandeinsatz erheblichen Sichtbehinderungen bis hin zur „Null Sicht”, so dass die Einhaltung der Abstandsregeln nach DIN/VDE 0132 nicht möglich ist. Deshalb schießt die Feuerwehr bei spannungsführenden Objekten zu ihrer eigenen Sicherheit im Zweifelsfall lieber Sprühstrahlen, auch da wo Vollstrahlen besser löschen könnten.But this provision is controversial in professional circles. Because in many cases, the preceding troops in the fire are subject to considerable obstruction to the "zero point of view", so that compliance with the distance rules after DIN / VDE 0132 not possible. Therefore, the fire brigade shoots at live objects for their own safety in case of doubt prefer spraying, even where full rays could clear better.

Der Deutsche Feuerwehrverband fordert daher schon lange neue technische Lösungen für die Aufgabe, einen Brand an spannungsführende Objekten zu bekämpfen, ohne den Feuerwehrmann zu gefährden.The German Fire Brigade Association has long been calling for new technical solutions to the task of fighting a fire on live objects without endangering the firefighter.

Diese Forderung kann erfüllt werden, wenn es gelingt. Vollstrahlfragmente zu schießen, die so kurz sind, dass über sie kein elektrischer Strom fließen kann.This requirement can be fulfilled if it succeeds. To shoot solid-jet fragments that are so short that no electric current can flow over them.

Vollstrahl Fragmente sind bekannt z. B. an Springbrunnen. Dort wird der austretende Vollstrahl durch ein gesteuertes Ventil vor der Düse abwechselnd unterbrochen und wieder freigegeben. Aber das geht nur bei dem niedrigen Vordruck und der relativ geringen Wassermenge eines Springbrunnens.Full jet fragments are known z. B. at fountains. There, the emerging jet is alternately interrupted by a controlled valve in front of the nozzle and released again. But that is only possible with the low admission pressure and the relatively small amount of water of a fountain.

Die Unterbrechung durch ein Ventil vor der Düse konnte aber noch nicht schnell genug bei der hohen Austrittgeschwindigkeit an einem Strahlrohr der Feuerwehr erreicht werden (z. B. 32 m/s bei 5 bar)However, the interruption by a valve in front of the nozzle could not yet be achieved quickly enough at the high exit velocity at a fire tube of the fire brigade (eg 32 m / s at 5 bar).

Benutzt man dafür ein rotierendes Dreiwegventil, dann kann der Wasserfluss beim Unterbrechen des Vollstrahls ohne Unterbrechung umgeleitet werden. Jedoch bilden sich beim Umschalten der Wege erhebliche Querströme und Schwingungen, die bei dieser harten Bedingung kaum beherrschbar sind.If you use a rotating three-way valve, then the water flow can be diverted without interruption when the full jet is interrupted. However, when switching the paths considerable cross currents and vibrations, which are hardly manageable in this hard condition form.

Ein Sitzventil kann zwar ohne solche Störungen schalten. Es würde aber den ankommenden Wasserstrom vollständig unterbrechen und damit heftige Stöße erzeugen, die Strahlrohr, Schlauch und Pumpe gefährden.A seat valve can indeed switch without such interference. But it would completely interrupt the incoming water flow and thus generate violent shocks endanger the jet pipe, hose and pump.

Es wurde auch vorgeschlagen, bei der Brandbekämpfung elektrischer Anlagen einen ununterbrochenen Düsenstrahl durch einen rotierenden Strahlablenker in fragmentierte und nicht fragmentierte Abschnitte zu zerteilen. (AktZ 10 2010 0480.0).It has also been proposed to divide an uninterrupted jet of jet into fragmented and non-fragmented sections by a rotating jet deflector in the firefighting of electrical equipment. (AktZ 10 2010 0480.0).

Lösungsolution

Die Erfindung löst die Aufgabe mit den Merkmalen der Ansprüche 1 bis 4.The invention solves the problem with the features of claims 1 to 4.

Das Hohlstrahlrohr hat eine Hohlstrahldüse 03, in der ein axial beweglicher Strahlformkegel 06 durch einen Kurbeltrieb 08 in rascher Folge abwechselnd in die Stellungen Vollstrahl und Sprühstrahl gestellt werden kann, wobei der Kurbeltrieb 08 von einer Turbine angetrieben wird, die manuell ein- und ausschaltbar ist, und in den Stellungen Vollstrahl und Sprühstrahl manuell blockiert werden kann.The hollow jet tube has a hollow jet nozzle 03 in which an axially movable beam cone 06 through a crank mechanism 08 in rapid succession alternately in the positions full jet and spray can be made, the crank mechanism 08 is powered by a turbine that can be manually switched on and off, and can be manually blocked in the positions full jet and spray.

Damit wird der Vollstrahl in geschlossene Fragmente aufgeteilt, die durch kurze Sprühstrahlabschnitte unterteilt sind. Die Sprühstrahl Abschnitte schützen den Feuerwehrmann vor der elektrischen Gefahr.Thus, the jet is divided into closed fragments, which are divided by short Sprühstrahlabschnitte. The spray jet sections protect the firefighter from the electrical danger.

Das Umschalten zwischen Vollstrahl und Sprühstrahl erfolgt fließend ohne Querströme und ohne Wirbelbildung. Die Wasserströme bei Vollstrahl und Sprühstrahl unterscheiden sich nur wenig, so dass beim Umschalten keine unzumutbare Stoßkräfte auftreten.Switching between full jet and spray jet is fluent without cross flows and without vortex formation. The streams of water at full jet and spray differ only slightly, so that no unreasonable impact forces occur when switching.

Das hier vorgeschlagene fragmentierte Hohlstrahlrohr kann in drei Betriebsarten betrieben werden:

  • – Fragmentieren = Abwechselnd Vollstrahl und Sprühstrahl in rascher Folge
  • – ununterbrochener Vollstrahl
  • – ununterbrochener Sprühstrahl
The fragmented hollow tube proposed here can be operated in three modes:
  • - Fragmentation = alternating full jet and spray in rapid succession
  • - continuous full jet
  • - continuous spray

Für die Betriebsarten ununterbrochener Vollstrahl und ununterbrochener Sprühstrahl wird der Kurbeltrieb bei geschlossenem Absperrventil 01 und ausgeschalteter Turbine (01 + 11 + 12) in den Stellungen Vollstrahl oder Sprühstrahl manuell eingestellt und blockiert.For the operating modes uninterrupted full jet and continuous spray, the crank mechanism with closed shut-off valve 01 and switched off turbine ( 01 + 11 + 12 ) is set and blocked manually in the full jet or spray position.

Der Strahlformkegel 06 ist ein Teil der Strahlformspindel 07, Dort sind alle axialen Kräfte hydraulisch derart ausgeglichen, dass sie die Turbine praktisch nicht belasten. Die muss nur die Reibungswiderstände ihrer wassergeschmierten Rotorlager 15 überwinden.The beam forming cone 06 is part of the beamforming spindle 07 There, all axial forces are hydraulically balanced so that they practically do not stress the turbine. The only needs the frictional resistance of their water-lubricated rotor bearings 15 overcome.

Die Stellungen Vollstrahl und Sprühstrahl sind am Strahlformkegel nur wenige Millimeter voneinander entfernt. Entsprechend klein ist der Kurbelradius am Kurbeltrieb. Deshalb sind die bei der Umlenkung der Strahlformspindel 07 auftretenden Beschleunigungskräfte ebenfalls geringThe full jet and spray jet positions are only a few millimeters apart at the cone. Correspondingly small is the crank radius on the crank mechanism. That is why they are at the deflection of the beam forming spindle 07 occurring acceleration forces also low

Die 1 un 2 zeigen es in der Vollstrahl StellungThe 1 U.N 2 show it in the full jet position

Die 3 zeigt es in der Sprühstrahl Stellung.The 3 it shows position in the spray jet.

Der von der Pumpe 01 kommende Wasserstrom gelangt durch das manuelle Absperrventil 02 zur Hohlstrahldüse 03: Er verlässt sie stellungsabhängig als Vollstrahl 04 oder als Sprühstrahl 05. In der Hohlstrahldüse 03 liegt der Strahlformkegel 04, der ein Teil der Teil der Strahlformspindel 07 ist. Diese wird von dem Kurbeltrieb 08 zwischen den Stellungen Vollstrahl und Sprühstrahl bewegt. Das von der Pumpe 01 gelieferte Wasser wird dabei durch den Umleitungskanal 09 um den Kurbeltrieb herum geführt.The one from the pump 01 incoming water flow passes through the manual shut-off valve 02 to the hollow jet nozzle 03 : He leaves her position-dependent as a full jet 04 or as a spray 05 , In the hollow jet nozzle 03 lies the beam shaping cone 04 which is part of the part of the beam forming spindle 07 is. This is from the crank mechanism 08 moved between the positions full jet and spray. That of the pump 01 supplied water is thereby through the diversion channel 09 guided around the crank mechanism.

Das geschieht in der Betriebsart – Fragmentieren – in rascher Folge, wobei der Kurbeltrieb von der Wasserturbine (10 + 11 + 12) angetrieben wird. Die besteht aus dem Turbinenlaufrad 10, der Turbinendüse 11 und dem Turbinenventil 12. Das Turbinenventil 12 kann manuell stufenlos geöffnet und geschlossen werden, wodurch der Düsenvordruck stufenlos eingestellt werden kann.This happens in the operating mode - Fragmentieren - in rapid succession, whereby the crank drive of the water turbine ( 10 + 11 + 12 ) is driven. This consists of the turbine wheel 10 , the turbine nozzle 11 and the turbine valve 12 , The turbine valve 12 can be manually opened and closed continuously, whereby the nozzle pre-pressure can be adjusted continuously.

Die Betriebarten – ununterbrochener Vollstrahl – und – ununterbrochener Sprühstrahl – werden bei geschlossenem Absperrventil 01 und geschlossenem Turbinenventil 12 mit dem Einstellrad 13 manuell eingestellt und mit dem Riegel 14 manuell blockiert.The operating modes - continuous jet - and - continuous spray jet - become with shut-off valve closed 01 and closed turbine valve 12 with the dial 13 set manually and with the latch 14 manually blocked.
