Description

Die vorliegende Erfindung betrifft eine automatische Vorrichtung zum Löschen eines Brandes, der an Bord eines Eisenbahnzuges während der Durchfahrt durch einen Tunnel ausbricht.The present invention relates to an automatic device for Extinguishing a fire on board a train during the Passage through a tunnel breaks out.

Das technische Gebiet der Erfindung betrifft das Bekämpfen von Bränden an Bord eines Eisenbahnzuges.The technical field of the invention relates to combating Fires on board a train.

Die Erfahrung hat gezeigt, daß die Zeit, die benötigt wird, um in einem Tunnel zu einer Unglücksstelle zu gelangen, dem Feuer ausreichend Zeit läßt, um sich auszubreiten, wobei die Folgen sehr ernst und umso weniger vorhersehbar sind, als die Rettungsmannschaften nie wissen, womit das Feuer geschürt wird, und meistens auch nicht, wo sich die Brandstelle genau befindet.Experience has shown that the time it takes to complete one To get tunnels to an accident site that gives fire enough time to spread, the consequences very serious and all the less predictable are when the rescue teams never know what is fueling the fire and most of the time not exactly where the fire is located.

Zum Stand der Technik wird die FR 2 139 495 B genannt, die eine automatische Vorrichtung mit einem unter Luftdruck stehenden Behälter beschreibt, der mehreren Wagen gemeinsam ist und eine Löschflüssigkeit enthält, und Leitungen, die die Flüssigkeit zu Sprinklerdüsen befördern, welche diese Flüssigkeit an der zuvor lokalisierten Brandstelle verteilen. Die Nachteile ergeben sich aus der Beschreibung selbst, die lediglich die Druckluft als Mittel zum Ausstoßen der Löschflüssigkeit erwähnt, wobei die Luftquelle der Bremskreis des Zuges selbst ist und damit das hohe Risiko birgt, daß die Funktionsweise dieses Kreises gestört wird.FR 2 139 495 B is referred to as prior art, the one describes automatic device with a container under air pressure, which is common to several cars and contains an extinguishing liquid, and lines that deliver the liquid to sprinkler nozzles, which Spread liquid at the previously located fire site. The disadvantages arise itself from the description, which only uses compressed air as a means of ejection of the extinguishing liquid mentioned, the air source being the brake circuit of the Zug itself is and thus carries the high risk that the functioning of this Circle is disturbed.

Gemäß der FR 2 769 508 A wird eine Vorrichtung vorgeschlagen, die überall und unter allen in der Beschreibung genannten Bedingungen funktionsfähig ist, wobei die Beschreibung den Schutz von Straßenfahrzeugen betrifft, die auf einem Eisenbahnzug transportiert werden (Huckepackverkehr), der aus speziellen Wagen mit Aufbauten besteht, an welchen die Sprinkleranlage befestigt ist. Der Nachteil, der sich aus der Bauweise des Eisenbahnzuges selbst ergibt, liegt in der Schwerfälligkeit des Verfahrens zum Be- und Entladen der Straßenfahrzeuge, die zum Ein- und Ausfahren hintereinander die ganze Länge des Wagenzuges befahren müssen.According to FR 2 769 508 A, a device is proposed which functional everywhere and under all conditions mentioned in the description is, the description relates to the protection of road vehicles that to be transported on a railroad train (piggyback), which consists of special There is a car with bodies to which the sprinkler system is attached is. The disadvantage of the construction of the train itself lies in the sluggishness of the procedure for loading and unloading the road vehicles, which extend and retract the entire length of the Must drive on the train.

Unter den zur Vereinfachung und Beschleunigung des Be- und Entladens der transportierten Straßenfahrzeuge angestrebten Lösungen wird die Verwendung von Plattformwagenzügen bevorzugt, die eine durchgehende Fläche bilden, auf der die Lastwagen an jeder Stelle ein- und ausfahren können. Diese Anordnung, die jegliche Aufbauten ausschließt, macht den Einsatz der in der Anmeldung 2769508 beschriebenen verzweigten Netze unmöglich und impliziert deren Ersatz durch andere Einrichtungen.Among those to simplify and accelerate loading and unloading of the road vehicles transported is the desired solution Use of platform wagon trains preferred which has a continuous area form on which the trucks can enter and exit at any point. This arrangement, which excludes any superstructure, makes the use of the in branched networks described in application 2769508 impossible and implied their replacement by other institutions.

Die vorliegende Erfindung hat somit die Aufgabe, eine Vorrichtung vorzuschlagen, die gegen einen während der Fahrt durch einen Tunnel an Bord eines Eisenbahnzuges ausbrechenden Brand wirksam eingesetzt werden kann, wobei der Zug aus Plattformwagen ohne Aufbauten besteht.The object of the present invention is thus a device propose to board one against while traveling through a tunnel a fire that breaks out in a train can be used effectively, the train consists of platform wagons without superstructures.

In bevorzugten Ausführungsformen umfaßt der Wagen eine in Längsrichtung verlaufende Leitung, die sich von einem Ende des Wagens zum anderen erstreckt, mehrere seitliche Sprinklerdüsen, die jeweils entlang der Längsränder der Plattform versenkt angeordnet sind, wobei die an die Leitung angeschlossenen Sprinklerdüsen so ausgerichtet sind, daß sie jeweils einen kompakten, in einer im wesentlichen senkrechten Ebene aufsteigenden Löschflüssigkeitsstrahl erzeugen, und einen ferngesteuerten Trennschieber zur Versorgung der Sprinklerdüsen mit Löschflüssigkeit. In preferred embodiments, the carriage comprises one in the longitudinal direction running pipe running from one end of the car to the other extends, several side sprinkler nozzles, each along the longitudinal edges the platform are sunk, the connected to the line Sprinkler nozzles are aligned so that they each have a compact, extinguishing liquid jet rising in a substantially vertical plane generate, and a remote-controlled gate valve for supply the sprinkler nozzles with extinguishing liquid.

Die Sprinklerdüsen sind um eine im wesentlichen horizontale und zur Längsachse des Wagens senkrechte Achse schwenkbar gelagert; ihre Öffnung ist mit einer Abdeckung aus elastischem Material geschützt.The sprinkler nozzles are around a substantially horizontal and Longitudinal axis of the carriage pivoted vertical axis; their opening is protected with a cover made of elastic material.

Gemäß einer weiteren Ausgestaltung schlägt die Erfindung einen Eisenbahnzug vor, der Straßenfahrzeuge trägt und in den folgendes integriert ist: ein Tankwagen mit Pumpe als Behälter für die Löschflüssigkeit und Mittel, welche die Flüssigkeit in ein Netz von Leitungen bis zu den Sprinklerdüsen in der Nähe des Brandherdes treiben. Diese Sprinklerdüsen sind im Zug angebracht und seitlich im Boden der Wagen außerhalb der Gesamtbreite der transportierten Fahrzeuge angeordnet, und sie spritzen den kompakten Löschflüssigkeitsstrahl nach oben und im wesentlichen senkrecht außerhalb der Seitenränder der Fahrzeuge.According to a further embodiment, the invention proposes a train who carries road vehicles and incorporates the following: a tanker truck with a pump as a container for the extinguishing liquid and agents the liquid in a network of lines up to the sprinkler nozzles in the Drive near the source of the fire. These sprinkler nozzles are installed on the train and laterally in the bottom of the wagons outside the total width of the transported Vehicles arranged, and they spray the compact jet of extinguishing liquid upwards and essentially vertically outside the side edges of the vehicles.

Gemäß einer dritten Ausgestaltung schlägt die Erfindung einen Eisenbahntunnel vor, der auf beiden Seiten der Mittelachse des Gleises einen Ablenker mit teilweise gekrümmtem Querschnitt umfaßt, wobei der Ablenker mit dem Tunnelbauwerk fest verbunden ist und sich über die gesamte Länge des Bauwerks oberhalb des durch die Fahrtbewegung des Zuges erzeugten Volumens erstreckt. Jeder Löschflüssigkeitsstrahl wird durch den Ablenker umgelenkt, so daß er sich im oberen Teil der transportierten Fahrzeuge ergießt.According to a third embodiment, the invention proposes a railway tunnel in front of a deflector on both sides of the central axis of the track with partially curved cross section, the deflector with the tunnel structure is firmly connected and extends over the entire length of the Structure above the volume generated by the train's movement extends. Every jet of extinguishing liquid is deflected by the deflector, so that it pours into the upper part of the transported vehicles.

Durch die Kombination der sich an Bord des zu schützenden Zuges befindlichen Einrichtungen einerseits und der mit dem durchfahrenen Bauwerk (Tunnel) fest verbundenen Einrichtungen andererseits ermöglicht die Erfindung somit, daß die gleichzeitig und komplementär verwendeten Einrichtungen auf einen im Zug entstehenden Brandherd einwirken, sogar bevor der Zug aus diesem Grund angehalten wird.By combining the train to be protected on board existing facilities on the one hand and with the building passed through On the other hand, (tunnel) permanently connected devices enable the invention thus that the facilities used simultaneously and complementarily affect a source of fire on the train, even before the train leaves it Reason is stopped.

Dank eines großen Löschflüssigkeitsvorrats verfügt man somit über eine Kombination von Einrichtungen, die das Versprühen der Flüssigkeit über einem Brandherd an Bord eines Zuges gewährleisten, sobald der Brand in einem Tunnel oder in irgendeinem, mit den Ablenkern ausgestatteten geschlossenen oder offenen Raum ausbricht.Thanks to a large supply of extinguishing liquid, you have a combination of devices that spray the liquid over Ensure a source of fire on board a train as soon as the fire in one Tunnel or in any closed area equipped with the deflectors or open space breaks out.

Die Vorteile der Erfindung ergeben sich aus dem Einsatz dieser Kombination von Einrichtungen, die es erlauben, unter den besonderen Bedingungen, die die Fahrt durch einen Tunnel darstellt, einen Brand sofort zu löschen oder einzudämmen, der an Bord eines Lastwagen auf Plattformwagen transportierenden Zuges ausbricht.The advantages of the invention result from the use of this combination of facilities that allow, under the special conditions, which represents the drive through a tunnel to extinguish a fire immediately or curb those transporting on platform trucks on a truck Train breaks out.

Eine bevorzugte Ausführungsform umfaßt zunächst mit dem den Tunnel bildenden Bauwerk 1 fest verbundene Ablenker 2, die vorzugsweise symmetrisch angeordnet sind und sich über die gesamte Länge des Tunnels auf jeder Seite des Gleises erstrecken. Jeder Ablenker umfaßt einerseits einen oberen, gekrümmten Teil 2a, der mit einem geradlinigen Abschnitt 2b endet, welcher in der Längsrichtung mit einem geraden oberen Abschnitt 2c abwechselt, und andererseits einen unteren, im wesentlichen geradlinigen (bzw. geraden) Teil 2d, der sich nach unten bis 2e erstreckt und dabei von der vertikalen Mittelachse M des Gleises V abweicht. Die Kanten 2b und 2c jedes Ablenkers haben ausreichend Abstand, um die Auslenkung des bzw. der Stromabnehmer 3 zu ermöglichen, die den Strom an der Fahrleitung 4 abnehmen.A preferred embodiment initially includes the tunnel forming structure 1 fixed deflector 2, which is preferably symmetrical are arranged and extending along the entire length of the tunnel on each Extend the side of the track. On the one hand, each deflector includes an upper, curved part 2a, which ends with a rectilinear section 2b, which in alternates in the longitudinal direction with a straight upper portion 2c, and on the other hand a lower, essentially rectilinear (or straight) part 2d, which extends down to 2e and thereby from the vertical central axis M of track V deviates. The edges 2b and 2c of each deflector are sufficient Distance in order to allow the deflection of the current collector (s) 3, which take the current on the catenary 4.

Die Vorrichtung gemäß der Erfindung umfaßt auch im Zug eingebaute seitliche Sprinklerdüsen 5, die im Fahrgestell oder im Boden des Transportwagens 6 entlang der Seitenränder und außerhalb der Gesamtbreite E-E des transportierten Fahrzeugs angebracht sind. Diese seitlichen Sprinklerdüsen wirken von unten nach oben und schwenken auf die eine und die andere Seite der Vertikalen in einem Winkel von 60-120° um eine horizontale und senkrecht zur Fahrtrichtung des Zuges verlaufende Achse 7, ohne daß ihre Öffnung in ihrer höchsten Stellung H1 (Fig. 5) aus der Ebene des Bodens herausragt.The device according to the invention also includes built-in trains lateral sprinkler nozzles 5, which are in the chassis or in the bottom of the trolley 6 along the side edges and outside the total width E-E of transported vehicle are attached. These side sprinkler nozzles work from the bottom up and swing to one side and the other of the Vertical at an angle of 60-120 ° around a horizontal and perpendicular to the Direction of the train extending axis 7 without its opening in its highest position H1 (Fig. 5) protrudes from the plane of the floor.

In einer Ausführungsvariante sind die Sprinklerdüsen am Ende einer Lanze 5a angebracht und unter den oben beschriebenen Bedingungen in einem ausreichenden Winkel (von etwa 160°) schwenkbar, so daß sie in der Stellung H3 (Fig. 5) vollständig eingezogen werden können. Die Aufgabe dieser Lanzen wird nachstehend in dem die Funktionsweise betreffenden Teil der Beschreibung erläutert.In one embodiment variant, the sprinkler nozzles are one at the end Lance 5a attached and in one under the conditions described above sufficient angle (of about 160 °) can be swiveled so that it is in the position H3 (Fig. 5) can be fully retracted. The task of these lances is described below in the operating part of the description explained.

Die Öffnung jeder Sprinklerdüse 5 ist vorzugsweise zylindrisch, wobei die Bohrung glatt ist, um einen kompakten Flüssigkeitsstrahl 17 mit maximaler Richtungswirkung zu liefern. Um zu vermeiden, daß die über die Mündungen der Sprinklerdüsen fahrenden Straßenfahrzeuge Verschmutzungen und Beschädigungen verursachen, weist die Sprinklerdüse ein Verschlußmittel auf, das auf die Gegenwart der zugeführten Löschflüssigkeit anspricht. Somit sind diese Öffnungen im Wartezustand mit einem Deckel oder Stopfen aus elastischem Material geschützt, der durch den bloßen Druck der Löschflüssigkeit abgerissen, ausgestoßen oder abgebrochen werden kann, wenn der Druck einen vorgegebenen Wert übersteigt, nachdem die auf dem Wagen 14 angebrachten Pumpen 15 in Gang gesetzt worden sind. Gemäß einer Ausführungsvariante können diese Stopfen auch schmelzen oder sich auflösen.The opening of each sprinkler nozzle 5 is preferably cylindrical, wherein the bore is smooth to a compact liquid jet 17 with maximum To deliver directional effect. To avoid that over the mouths of the Sprinkler nozzles driving road vehicles dirt and damage cause, the sprinkler nozzle has a closure means that on the Presence of the supplied extinguishing liquid. So these are openings while waiting with a lid or stopper made of elastic material protected, torn off by the mere pressure of the extinguishing liquid, expelled or can be canceled if the pressure reaches a predetermined Value after the pumps 15 mounted on the carriage 14 in Gear has been set. According to an embodiment variant, these can Melt the stopper or dissolve.

Quer oder mittig angeordnete Sprinklerdüsen 9 bzw. 10 mit diffusem Strahl, die außerdem im Boden des Wagens 6 versenkt angeordnet sind, vervollständigen die Ausstattung des Wagens.Sprinkler nozzles 9 and 10, arranged transversely or centrally, with diffuse Complete the beam, which is also sunk in the bottom of the carriage 6 the equipment of the car.

Die Löschflüssigkeit wird mit Hilfe der Pumpen 15 über das Leitungsnetz 11, von dem sich ein Teil von einem Ende jedes Wagens 6 zum anderen erstreckt, und über biegsame Verbindungselemente 12 unter Druck von dem Tankwagen 14 zu den Sprinklerdüsen 5, 9, 10 befördert.The extinguishing liquid is pumped 15 through the network 11, part of which extends from one end of each carriage 6 to the other extends, and via flexible connecting elements 12 under pressure from the Tanker 14 transported to the sprinkler nozzles 5, 9, 10.

Erfassungsvorrichtungen bekannter Art sind an geeigneter Stelle und in geeigneten Abständen wie beispielsweise bei 13 an den Wänden des Tunnels 1 angebracht, um aktiviert zu werden, wenn ein meistens im oberen Teil des transportierten Fahrzeugs ausbrechendes oder bereits entdecktes Feuer an ihnen vorbeifährt. Detection devices of known type are in a suitable place and at suitable intervals, such as at 13 on the walls of the tunnel 1 attached to be activated when a mostly in the upper part of the transported or already discovered fire on them passes by.

Das auf diese Weise empfangene Signal wird zum Zug übertragen, nämlich einerseits zur Lokomotive und zum Zugpersonal, andererseits zu einer automatischen Vorrichtung zum Öffnen eines Trennschiebers 16 des in Brand geratenen Wagens und zum Betätigen der Pumpen 15 des Tankwagens 14. (Der Schieber 16 ist lediglich in Fig. 3 dargestellt).The signal received in this way is transmitted to the train, namely on the one hand to the locomotive and to the train staff, on the other hand to one automatic device for opening a slide valve 16 of the fire advised wagon and for actuating the pumps 15 of the tank wagon 14. (The slider 16 is only shown in Fig. 3).

Die Sprinklerdüsen - oder eine Gruppe von Sprinklerdüsen - des in Brand geratenen Wagens verspritzen dann die Löschflüssigkeit mit der nötigen Geschwindigkeit auf einer Strecke 17, die im wesentlichen die Innenseite des geradlinigen Abschnitts 2d der Ablenker berührt, in Richtung zur Innenwölbung des oberen Teils 2, wo der Strahl zu den geraden Teilen 2b und 2c umgelenkt wird, gegen die die Löschflüssigkeit unter Beibehaltung einer ausreichenden Restgeschwindigkeit in großen Mengen auf den oberen Teil 18 des transportierten Straßenfahrzeugs wieder herunterfällt.The sprinkler nozzles - or a group of sprinkler nozzles - des in A car that has caught fire will then spray the extinguishing liquid with the necessary liquid Speed on a route 17 which is essentially the inside of the rectilinear section 2d touches the deflector, towards the inner curvature the upper part 2, where the beam is redirected to the straight parts 2b and 2c against which the extinguishing liquid while maintaining sufficient Remaining speed in large quantities on the upper part 18 of the transported Road vehicle falls down again.

Um dieses Ziel zu erreichen, ist es wichtig, daß der Löschflüssigkeitsstrahl 17 kompakt ist und in einer Richtung aufsteigt, die der Vertikalen so nah wie möglich ist. Um dieser Bedingung nahe zu kommen, ist es notwendig, den relativen Windeffekt zumindest teilweise auszugleichen, der entlang der Seitenwände durch die Bewegung des Zuges entsteht. Eine automatische Ausrichtevorrichtung bekannter Art, die beispielsweise von einem pneumatischen oder hydraulischen Stellglied gesteuert wird, hält die Sprinklerdüsen entweder in der zur vorderen Seite des fahrenden Zuges geneigten Stellung H2 oder H3 oder senkrecht in der Stellung H1, wenn der Zug angehalten hat. Um die Folgen des Windeffekts noch weiter zu reduzieren, verringern die Lanzen 5a die freie Strekke des Strahls 17 und somit seine Zerstreuung, bevor er auf die Ablenker 2 auftrifft.To achieve this goal it is important that the jet of extinguishing liquid 17 is compact and rises in a direction that the vertical is as close as possible. To get close to this condition, it is necessary to at least partially offset the relative wind effect along the Sidewalls are created by the movement of the train. An automatic alignment device known type, for example of a pneumatic or hydraulic actuator is controlled, the sprinkler nozzles either in the position H2 or H3 or inclined towards the front of the moving train vertically in position H1 when the train has stopped. To the consequences of To further reduce the wind effect, the lances 5a reduce the free range of the beam 17 and thus its dispersion before it strikes the deflector 2.

Unabhängig von den Sensoren 13 können weitere Sensoren über die Schieber 16a auf die zentralen Sprinklerdüsen 10 einwirken, wenn im unteren Teil des transportierten Fahrzeugs ein Brand ausbricht. Independent of the sensors 13, further sensors can be operated via the Act slider 16a on the central sprinkler nozzles 10 when in the lower A fire breaks out in part of the transported vehicle.

Um den Abstand, d.h. die Länge der Leitung zwischen dem Tankwagen mit Pumpe und dem am weitesten entfernten Plattformwagen 6 zu verringern, liegt der Tankwagen vorzugsweise in der Mitte des geschützten Wagenzuges, wodurch nur zwei einzelne Manövrierbereiche zum seitlichen Ein- und Ausfahren der Fahrzeuge entstehen.By the distance, i.e. the length of the line between the tanker with pump and the most distant platform trolley 6, the tanker is preferably in the middle of the protected train, whereby only two individual maneuvering areas for lateral entry and exit Extend the vehicles.

Wenn beispielsweise pro Meter Wagenlänge eine seitliche Sprinklerdüse vorgesehen ist, kann die Anzahl von Sprinklerdüsen je Wagen auf 40 (20 auf jeder Seite) veranschlagt werden, um eine Fläche von ungefähr 60m2 förmlich zu "überschwemmen". Bei einem Durchsatz von 15 I/min/m2 würde eine Flüssigkeitsmenge in der Größenordnung von 54 m3/h verspritzt werden. Bei diesem Durchsatz würde der Inhalt eines im Zug integrierten Tankwagens von 60 m3 somit einen Betrieb von mehr als einer Stunde gewährleisten.When a lateral sprinkler nozzle is provided, for example, per meter carriage length, the number of sprinkler heads 40 on each car (20 on each side) can be estimated, "flood" to an area of about 60m 2 formally. With a throughput of 15 l / min / m 2 , an amount of liquid of the order of 54 m 3 / h would be sprayed. At this throughput, the content of a tank truck of 60 m 3 integrated in the train would thus guarantee operation for more than an hour.

Es ist anzunehmen, daß infolge einer solchen Ausstattung das zusätzliche Gewicht eines Zuges mit 35 bis 40 Wagen weniger als 3% des gesamten Fahrgewichts ausmacht und die für den Betrieb jeder Motorpumpe erforderliche Leistung zwischen 30 und 50 kW beträgt.It can be assumed that the additional Weight of a train with 35 to 40 wagons less than 3% of the total Driving weight and the necessary for the operation of each motor pump Power is between 30 and 50 kW.

Claims (9)

  1. A railway truck (6) with a platform for road vehicles, characterised in that it comprises a sprinkler installation (5,9,10) located in the platform.
  2. A railway truck according to claim 1, characterised by a line (11) extending in the longitudinal direction from one end of the truck to the other, by a plurality of lateral sprinkler nozzles (5), each countersunk along the longitudinal edges of the platform and so aligned as to produce a compact extinguishing liquid jet (17) rising in a substantially vertical plane, and by an isolating slide (16) to supply the sprinkler nozzles via the line (11) in dependence on a remote control signal.
  3. A railway truck according to claim 1 or 2, characterised in that the sprinkler nozzle or nozzles is/are mounted to be pivotable along a substantially horizontal axis (7) perpendicular to the longitudinal axis of the truck.
  4. A railway truck according to any one of claims 1 to 3, characterised in that the sprinkler nozzle comprises a closure means which responds to the extinguishing liquid delivered to the sprinkler nozzle.
  5. A railway truck according to claim 4, characterised in that the closure means consists essentially of a lid or plug which is torn away, ejected or broken off when the pressure of the liquid exceeds a predetermined value, or which melts or dissolves by the influence of the liquid.
  6. A railway train with a tank wagon (14) containing an extinguishing liquid, with pumps (15) and lines (11) and hoses (12) for conveying the extinguishing liquid to the trucks of the train comprising trucks according to any one of claims 1 to 5.
  7. A railway tunnel, characterised in that it comprises a deflector (2) for an ascending extinguishing liquid jet (17) so that the extinguishing liquid jet is deflected to the upper part (18) of the vehicle or vehicles being transported.
  8. A tunnel according to claim 7, which in the upper part comprises two elongate curved deflectors (2), which are symmetrical to the vertical central plane (M) of the track (V).
  9. A tunnel according to claim 7 or 8, characterised in that the deflector (12) extends over substantially the entire length of the tunnel and has a curved upper part (2a) which terminates in rectilinear portions (2b,2c) having alternately different inclinations and a substantially rectilinear downwardly pointing lower part (2d).
