Description
DISPOSITIF D'EXTINCTION AUTOMATIQUE D'INCENDIE INTEGRE A UN CONVOI FERROVIAIRE AUTOMATIC FIRE EXTINGUISHING DEVICE INTEGRATED IN A RAIL CONVEYOR
La présente invention a pour objet un dispositif d'extinction automatique d'incendie survenant sur un convoi ferroviaire.The present invention relates to an automatic fire extinguishing device occurring on a railway convoy.
Le secteur technique de l'invention est celui de la lutte contre les incendies à bord d'un convoi ferroviaireThe technical sector of the invention is that of fire fighting on board a railway convoy
La demande de brevet GB 2.139.495 A (Total Walther Feuerschutz) décrit un dispositif automatique de protection incendie pour véhicules équipés d'un système d'air comprimé qui est particulèrement adapté pour équiper un train souter- rain constitué de plusieurs voitures attelées de transport de voyageurs. Le dispositif comporte un réservoir, commun à plusieurs voitures, qui contient un matériau extincteur sous pression d'air et une canalisation raccordant ce réservoir à des arroseurs ( sprinklers ) . L'air comprimé contenu dans le réservoir provient du circuit d'air comprimé équipant le véhicule, en particulier du circuit de freinage. Un conduit d'alimentation du réservoir en air comprimé est équipé d'un clapet anti- retour pour assurer un remplissage automatique dudit réservoir par de l'air comprimé. La canalisation de transport du matériau extincteur (constitué par de l'eau salée) est divisée en plusieurs branches, alimente les arroseurs des différents véhicules du train et comporte un raccord flexible entre deux véhicules.Patent application GB 2,139,495 A (Total Walther Feuerschutz) describes an automatic fire protection device for vehicles equipped with a compressed air system which is particularly suitable for equipping an underground train consisting of several coupled transport cars of travelers. The device includes a tank, common to several cars, which contains an extinguisher material under air pressure and a pipe connecting this tank to sprinklers. The compressed air contained in the tank comes from the compressed air circuit fitted to the vehicle, in particular from the braking circuit. A supply line for the compressed air tank is equipped with a non-return valve to ensure automatic filling of said tank with compressed air. The fire extinguisher material transport pipe (consisting of salt water) is divided into several branches, feeds the sprinklers of the different vehicles of the train and includes a flexible connection between two vehicles.
Ce système comporte des inconvénients . Tout d'abord l'usage de l'air comprimé comme unique moyen de propulsion du liquide extincteur n'est pas compatible avec un réservoir de capacité suffisante pour assurer un fonctionnement efficace du dispositif anti-incendie. Un tel réservoir, résistant à la pression requise, est, en outre, d'un encombrement trop important pour être implanté dans un véhicule de transport de personnes. Ensuite, l'utilisation de l 'air comprimé du circuit de freinage est de nature à perturber gravement le fonctionnement dudit circuit, principalement par un prélèvement excessif d'air comprimé: il est en effet impossible de prévoir d'avance combien d'arroseurs s'ouvriront , par conséquent quel sera le débit d'eau, donc d'air .
Un autre inconvénient est le risque d'indisponibilité de l'ensemble du dispositif anti-incendie en cas d'avarie du circuit de freinage, par exemple à la suite d'accident à l'origine de l'incendie ou consécutif à celui-ci. De même, est incompatible avec le résultat recherché la mise en service d'un compresseur additionnel (cf revendication 11) dont le débit d'air en haute pression devrait être au moins égal au débit total.de tous les arroseurs en service. En matière ferroviaire, on connaît l'usage de trains de secours comportant, avec d'autres éléments, un wagon-citerne-pompe armé de lances d'incendie et utilisables par des équipes de servants en approche d'un convoi sinistré.This system has drawbacks. First of all, the use of compressed air as the sole means of propelling the extinguishing liquid is not compatible with a tank of sufficient capacity to ensure efficient operation of the fire-fighting device. Such a reservoir, resistant to the required pressure, is, in addition, too large in size to be installed in a passenger vehicle. Then, the use of compressed air from the braking circuit is likely to seriously disturb the operation of said circuit, mainly by an excessive withdrawal of compressed air: it is indeed impossible to predict in advance how many sprinklers s 'will open, therefore what will be the flow of water, therefore air. Another disadvantage is the risk of unavailability of the entire fire-fighting device in the event of damage to the braking circuit, for example following an accident causing or following the fire. . Similarly, it is incompatible with the desired result the commissioning of an additional compressor (see claim 11) whose air flow at high pressure should be at least equal to the total flow of all sprinklers in service. In railway matters, the use of emergency trains is known, comprising, with other elements, a tank-wagon pump armed with fire hoses and usable by teams of servants approaching a disaster-stricken convoy.
Cependant, le développement du ferroutage, notamment celui empruntant des tunnels sur de grandes distances, soulève la question d'une meilleure sécurité des convois et l'opportunité de disposer de nouveaux équipements embarqués d'extinction automatique d'incendie.However, the development of piggyback transport, particularly that using tunnels over long distances, raises the question of better convoy security and the advisability of having new on-board equipment for automatic fire extinguishing.
En effet, l'installation dans les tunnels ferroviaires d'arroseurs à poste fixe sur les parois de l'ouvrage n'est opérationnelle que pendant le franchissement de celui-ci et nécessite une procédure complexe d'interventions séquentielles (détection, localisation, arrêt du convoi) préalablement à la mise en action des arroseurs . Même en disposant , malgré son coût dans un long tunnel, d'une couverture continue et d'emprise suffisante, il se produit inévitablement un retard important à l'attaque du feu et donc un risque non négligeable de son extension .Indeed, the installation in sprinklers of stationary sprinklers on the walls of the structure is only operational during the crossing of it and requires a complex procedure of sequential interventions (detection, location, stop of the convoy) before putting the sprinklers into action. Even if, despite its cost in a long tunnel, continuous coverage and sufficient footprint, there inevitably occurs a significant delay in the attack of fire and therefore a significant risk of its extension.
La présente invention a pour objet de proposer un dispositif simple à construire, à entretenir et à utiliser, qui remédie aux inconvénients énoncés ci-avant et dont la disponibilité, la puissance et l'efficacité soient adaptées au risque particulier que constitue un incendie à bord d'un convoi ferroviaire en marche.The object of the present invention is to provide a device which is simple to build, maintain and use, which overcomes the drawbacks set out above and whose availability, power and efficiency are adapted to the particular risk of a fire on board. of a moving rail convoy.
L'objectif de l'invention consiste à mettre en oeuvre sur un ensemble de véhicules circulant en convoi, principalement sur voie ferrée, des moyens pour agir sur un foyer d'incendie, naissant ou peu développé, qui surviendrait ou se développerait sur ledit convoi et l'éteindre ou le circonscrire, même pendant la marche dudit convoi et ceci avant que soit possible toute autre intervention extérieure à ce convoi.
Selon un premier aspect, cet objectif est atteint par le dispositif selon l'invention pour éteindre ou circonscrire un toyer d'incendie, ce dispositif comportant un réservoir, des moyens pour introduire dans ce réservoir un fluide extincteur, de préférence à l'état liquide, et des moyens pour propulser ledit liquide dans un réseau de canalisations jusqu'audit foyer d'incendie, caractérisé en ce que ledit réservoir, lesdits moyens pour introduire ledit liquide extincteur et le propulser dans un réseau de canalisations, ainsi que ledit réseau, sont intégrés à un convoi de véhicules ferroviaires et se déplacent avec ledit convoi en restant opérationnels .The objective of the invention is to implement on a set of vehicles traveling in convoys, mainly on railways, means for acting on a fire source, incipient or little developed, which would occur or develop on said convoy and turn it off or circumscribe it, even while the convoy is in progress, before any other intervention outside this convoy is possible. According to a first aspect, this objective is achieved by the device according to the invention for extinguishing or circumscribing a fire heater, this device comprising a reservoir, means for introducing into this reservoir an extinguishing fluid, preferably in the liquid state. , and means for propelling said liquid in a network of pipes up to said fire hearth, characterized in that said tank, said means for introducing said extinguishing liquid and propelling it in a network of pipes, as well as said network, are integrated into a convoy of railway vehicles and move with said convoy while remaining operational.
Selon un deuxième aspect, l'invention consiste à équiper un wagon-citerne de moyens permettant, lors d'un incendie à bord d'un convoi incorporant ledit wagon-citerne,de délivrer, à chaque extrémité du wagon - citerne , un fluide extincteur sous pression par un conduit d'extrémité équipé d'un raccord de liaison à un conduit équipant deux wagons ou voitures faisant partie du convoi et disposés de part et d'autre du wagon-citerne, pour la distribution auxdits wagons ou voitures du fluide extincteur stocké dans la citerne du wagon-citerne.According to a second aspect, the invention consists in equipping a tank car with means making it possible, during a fire on board a convoy incorporating said tank car, to deliver, at each end of the tank car, an extinguishing fluid under pressure by an end pipe fitted with a connection fitting to a pipe fitted to two wagons or cars forming part of the convoy and arranged on either side of the tank wagon, for the distribution to said wagons or cars of the extinguishing fluid stored in the tank car tank.
Selon un troisième aspect, l'invention consiste à proposer un wagon-citerne (pour convoi ferroviaire) qui comporte une citerne ( apte à recevoir un fluide de lutte contre les incendies en particulier de l'eau) montée sur (ou intégrée à) un châssis équipé de manière à lui permettre de circuler sur voie ferrée, par exemple de boggies, Caractérisé en ce qu'il comporte :According to a third aspect, the invention consists in proposing a tank wagon (for railway convoy) which comprises a tank (suitable for receiving a fire fighting fluid, in particular water) mounted on (or integrated into) a chassis equipped to allow it to travel on railways, for example bogies, Characterized in that it comprises:
- deux portions de conduit de transport dudit fluide, s'éten- dant respectivement jusqu'à chacune des deux extrémités (longitudinales) du châssis (ou du wagon), raccordé à la citerne et terminé par un dispositif 9 de raccordement disposé à l'extrémité du châssis ,two portions of the conduit for transporting said fluid, extending respectively to each of the two ends (longitudinal) of the chassis (or of the wagon), connected to the tank and terminated by a connection device 9 arranged at the chassis end,
- au moins une pompe raccordée à la citerne pour pouvoir y aspirer ledit fluide et raccordée à chacune des portions de conduit pour pouvoir y refouler ledit fluide.- At least one pump connected to the tank to be able to suck said fluid therein and connected to each of the pipe portions so as to be able to discharge said fluid there.
On utilise de préférence un wagon-citerne dont le réservoir (la citerne) a une contenance supérieure à 10 m3 et généralement inférieure à 80 m3, en particulier située dans une plage entre 40 et 80 m3..
On dispose ainsi d'une réserve importante de fluide extincteur, généralement liquide.It is preferable to use a tank car whose tank (the tank) has a capacity greater than 10 m 3 and generally less than 80 m 3 , in particular situated in a range between 40 and 80 m 3. There is thus a large reserve of extinguishing fluid, generally liquid.
Il est décrit plus loin un mode préférentiel de réalisation dans lequel le wagon citerne est équipé de deux pompes pouvant fonctionner simultanément. Le raccordement de ces pompes aux deux portions de conduit d'extrémité du wagon-citerne permet aux deux pompes de délivrer le liquide extincteur sous pression, indifférement à l'un ou à l'autre des deux conduits d'extrémité pour alimenter la partie du convoi située en avant ou en arrière du wagon-citerne ou bien aux deux portions de conduit simultanément pour alimenter à la fois les parties du convoi disposées en amont ou en aval.A preferred embodiment is described below in which the tank wagon is equipped with two pumps which can operate simultaneously. The connection of these pumps to the two portions of the tank car end pipe allows the two pumps to deliver the extinguishing liquid under pressure, either to one or the other of the two end pipes to supply the part of the convoy located in front of or behind the tank car or else to the two portions of conduit simultaneously to supply both the parts of the convoy arranged upstream or downstream.
Afin d'assurer une distribution du liquide extincteur dans une partie - dite protégée - du convoi comprenant plu- sieurs wagons ou voitures attelés les un aux autres, à la suite des autres et attelés au wagon-citerne, chacun(e) de ces wagons ou voitures est doté(e) d'une canalisation longitudinale s 'étendant sur toute la longueur du wagon (ou voiture) et sur laquelle sont raccordées des canalisations secondaires aptes à délivrer le liquide extincteur à des arroseurs.In order to ensure the distribution of the extinguishing liquid in a part - known as protected - of the convoy comprising several wagons or cars coupled to one another, following the others and coupled to the tank car, each of these wagons or cars has (e) a longitudinal pipe extending over the entire length of the wagon (or car) and to which are connected secondary pipes capable of delivering the extinguishing liquid to sprinklers.
Les canalisations longitudinales de tous les wagons ou voitures de la partie protégée du convoi sont reliées entre elles par des portions de canalisations, de préférence flexibles, pour assurer une continuité du réseau de délivrance du fluide extincteur dans toute la partie protégée du convoi. Ces portions de canalisations sont de préférence intégrées à chaque portion de conduit d'extrémité du wagon-citerne, ainsi qu'à chaque extrémité de la canalisation longitudinale de chaque wagon ou voiture. Selon un autre aspect, l'invention consiste à proposer un wagon destiné au transport de véhicule routier et équipé de ladite canalisation longitudinale d'acheminement du fluide extincteur.The longitudinal pipes of all the wagons or cars in the protected part of the convoy are interconnected by portions of pipes, preferably flexible, to ensure continuity of the network for delivering the extinguishing fluid throughout the protected part of the convoy. These pipe portions are preferably integrated into each portion of the end pipe of the tank car, as well as at each end of the longitudinal pipe of each wagon or car. According to another aspect, the invention consists in proposing a wagon intended for transporting a road vehicle and equipped with said longitudinal pipe for conveying the extinguishing fluid.
Les avantages de l'invention apparaissent en ce qu'ils consistent à mettre en oeuvre immédiatement les moyens d'extinction d'un incendie à bord d'un convoi ferroviaire quels que soient le lieu et les circonstances dans lesquelles se déclare ledit incendie, que ce soit à l'air libre ou en traversée de tunnel, à l'arrêt ou en marche et ceci même en cas de plusieurs feux se déclarant simultanément.

Chaque portion avant et arrière de la canalisation 7 s'étend, 5 en aval de la boucle by pass 7/8 et a travers les vannes 27a jusqu'à un dispositif d'extrémité 9 permettant son raccordement à une autre canalisation. Une conduite 7b relie les deux boucles by-pass 7/8 avant et arrière à travers la vanne 7c. Un montage selon l'exemple ci-dessus permet l'isolement ou au 10 contraire la banalisation des équipements avant et arrière du wagon-citerne-pompe. L'énergie nécessaire au fonctionnement des moto-surpresseurs est tirée d'une source indépendante de celle utilisée pour la marche du convoi, par exemple d'un moteur thermique .Each of these motor boosters is connected upstream (suction side) to the low point 6 of the tank 2 by a portion of a longitudinal pipe 7 and, downstream, (discharge side) ment) to a 7/8 bypass loop piping on which a non-return valve 7a prohibits the return of the 8 to 6 extinguishing liquid but allows its passage in the opposite direction. Each front and rear portion of the pipe 7 extends, 5 downstream of the bypass loop 7/8 and through the valves 27a to an end device 9 allowing its connection to another pipe. A pipe 7b connects the two front and rear bypass loops 7/8 through the valve 7c. An assembly according to the example above allows the isolation or on the contrary the trivialization of the front and rear equipment of the pump-tank car. The energy necessary for the operation of the motor boosters is drawn from a source independent of that used for running the convoy, for example from a heat engine.

Le dispositif selon l'invention s'applique aussi à des véhicules de transport routiers de marchandises fermés (fourgons) FI et F2 transportés par ledit convoi C et comportant des moyens pour en arroser l'intérieur dans le cas ouThe device according to the invention also applies to closed road transport vehicles (vans) FI and F2 transported by said convoy C and comprising means for watering the interior thereof in the case where
25 un feu y survient .25 a fire occurs.
Dans un premier mode préférentiel de réalisation, lesdits fourgons Fl comportent un toit ouvrant longitudinale- ment au moyen de dispositifs connus (non représentés) et de préférence dans sa partie médiane 28; le wagon porteurIn a first preferred embodiment, said vans F1 comprise a roof opening longitudinally by means of known devices (not shown) and preferably in its middle part 28; the carrier wagon
30 10 comporte au moins une rangée d'arroseurs 16 placée immédiatement sous sa toiture et au- dessus de la partie ouvrante 28 du toit dudit fourgon.30 10 comprises at least one row of sprinklers 16 placed immediately under its roof and above the opening part 28 of the roof of said van.
Dans un deuxième mode de réalisation, le wagon 10 comporte un tronçon 15b, raccordé en 15C à la canalisationIn a second embodiment, the wagon 10 has a section 15b, connected at 15C to the pipeline
35 12 et terminé par un orifice de raccordement 30, lequel est placé en aval d'une vanne motorisée 33. L'intérieur du fourgon F2 comporte un réseau 13b porteur d'arroseurs 18 alimentés en liquide extincteur par un dispositif de raccordement 31, propre au fourgon F2 , extérieur à celui-ci et relié te porai-35 12 and terminated by a connection orifice 30, which is placed downstream of a motorized valve 33. The interior of the van F2 comprises a network 13b carrying sprinklers 18 supplied with extinguishing liquid by a connection device 31, clean in the van F2, outside of it and connected to you
40 rement à l'orifice 30 par une canalisation flexible 32.
La vanne motorisée 33, intégrée au dispositif du convoi C est actionnée par l'intermédiaire d'une liaison temporaire 34, par exemple électrique, avec un détecteur d'incendie 35, propre au fourgon F2 et de technique connue. L'avantage d'équiper les véhicules transportés de ces moyens complémentaires est d'augmenter considérablement l'efficacité du dispositif selon l'invention en attaquant un feu naissant dans l'enceinte d'un fourgon fermé, avant même que ledit feu ne se soit déclaré à l'extérieur dudit fourgon.40 rement to the orifice 30 by a flexible pipe 32. The motorized valve 33, integrated into the device of the convoy C is actuated via a temporary connection 34, for example electrical, with a fire detector 35, specific to the van F2 and of known technique. The advantage of equipping the transported vehicles with these additional means is to considerably increase the efficiency of the device according to the invention by attacking an incipient fire in the enclosure of a closed van, even before said fire has declared outside of said van.
Dans un mode préférentiel de formation d'un convoi ferroviaire protégé contre l'incendie par un dispositif selon l'invention, le ou les wagojis-citerne-pompe sont placés sensiblement au milieu Y du convoi C, comme illustré Fig. 6. FONCTIONNEMENTIn a preferred mode of forming a train convoy protected against fire by a device according to the invention, the wagojis-tank-pump are placed substantially in the middle Y of the convoy C, as illustrated in FIG. 6. OPERATION
La mise en état de marche s'opère, comme pour une installation de type antérieurement connu, par remplissage préalable des canalisations principales, des canalisations secondaires, des réseaux ramifiés alimentant des arroseurs à obturation thermo-fusible, ainsi que de la citerne (réservoir) 2.The operation is carried out, as for an installation of a previously known type, by prior filling of the main pipes, secondary pipes, branched networks supplying sprinklers with heat-fusible closure, as well as the tank (tank) 2.
Dans un mode opératoire préférentiel, on réserve dans celle-ci le volume convenable pour qu'y soit comprimé, au-dessus de la surface du liquide extincteur, de l'air en quantité telle que la totalité du liquide soit chassée éven- tuellement avec une pression résiduelle suffisante pour conserver une efficacité minimale aux arroseurs -en cas de défaillance des moto-surpresseurs .In a preferred procedure, the volume is reserved therein so that there is compressed therein, above the surface of the extinguishing liquid, air in an amount such that all of the liquid is optionally expelled with sufficient residual pressure to maintain minimum efficiency for sprinklers - in the event of failure of the motor boosters.
Cette disposition n'est donc pas indispensable au fonctionnement du dispositif mais assure, αμelles que soient les circonstances, l'arrosage de la zone sinistrée dès l'ouverture des arroseurs 16. Elle implique, par contre:This arrangement is therefore not essential for the operation of the device but ensures, as the circumstances may be, that the disaster area is watered as soon as the sprinklers are opened 16. It does, however, involve:
- de disposer d'un réservoir éprouvé pour être utilisé à la pression initiale de fonctionnement,- have a proven reservoir for use at the initial operating pressure,
- la précaution de remplir, au moins en aval des moto-surpres- seurs , toutes les canalisations avec un liquide extincteur contenant un produit anti-gel,- the precaution of filling, at least downstream of the motor boosters, all the pipes with an extinguishing liquid containing an anti-freeze product,
- ou d'équiper lesdites canalisations de réchauffeurs ou de tout autre moyen de protection contre le gel.
Dans un autre mode opératoire préférentiel, la vanne 27a du wagon 1, motorisée, est fermée en position de veille et l'ensemble des canalisations 12, 23, 13, 15, est, seul, rempli d'air comprimé. Cette disposition évite l'usage du produit anti-gel. Elle retarde, par contre, légèrement l'arrivée du fluide extincteur sur le foyer d'incendie.- or to equip said pipes with heaters or any other means of protection against freezing. In another preferred operating mode, the valve 27a of wagon 1, motorized, is closed in the standby position and all of the pipes 12, 23, 13, 15, is, alone, filled with compressed air. This provision avoids the use of anti-freeze product. However, it slightly delays the arrival of the extinguishing fluid on the fire.
Bien entendu, la combinaison de ces différentes dispositions est possible, par exemple en plaçant des réchauffeurs sur les seules canalisations 7, 12, 23 et en remplissant les ramifications 13, et 15 d'un mélange anti-gel. Des clapets anti-retour 100 disposés aux points de raccordement a- vec la canalisation 12 maintiennent la séparation des deux fluides .Of course, the combination of these different arrangements is possible, for example by placing heaters on the only pipes 7, 12, 23 and filling the branches 13, and 15 with an anti-freeze mixture. Non-return valves 100 arranged at the connection points with the pipe 12 maintain the separation of the two fluids.
Dans une variante de réalisation, un réservoir sous pression 101, de 20 à 50 litres de capacité, semblable à un vase d'expansion à vessie, est placé sur chaque wagon 10, en dérivation du réseau ramifié 13, et 15 et en aval desdits clapets anti-retour. Ce réservoir compense les fuites éventuelles de ces clapets vers la canalisation 12, maintient dans le réseau ramifié une réserve d'énergie contribuant à la propulsion initiale de liquide extincteur et masque ainsi le temps, très court mais cependant nécessaire au démarrage et à la mise en régime des moto-surpresseurs .In an alternative embodiment, a pressure tank 101, with a capacity of 20 to 50 liters, similar to a bladder expansion vessel, is placed on each wagon 10, bypassing the branched network 13, and 15 and downstream of said non-return valves. This reservoir compensates for any leaks from these valves to the line 12, maintains in the branched network a reserve of energy contributing to the initial propulsion of extinguishing liquid and thus masks the time, which is very short but nevertheless necessary for starting and setting up. scheme of motor boosters.
Le convoi ainsi protégé contre l'incendie par le dispositif selon l'invention circule alors normalement en véhiculant son propre dispositif d'extinction automatique.The convoy thus protected against fire by the device according to the invention then circulates normally by carrying its own automatic extinguishing device.
En cas de sinistre (départ de feu) le processus est sensiblement le même que celui des installations fixes déjà existantes. Indépendament de la chute de pression provo- quée dans l'installation par la fusion d'un obturateur 17, les informations transmises par d'autres dispositifs de détection et d'alarme sont acheminées aux équipements d'extinction par des moyens connus, par exemple électriques, pneumatiques ou hydrauliques. Ainsi, selon le mode de déclenchement adopté, la chaleur dégagée par le foyer d'incendie provoque, en quelques secondes et en tous cas à très bref délai, soit la fusion des obturateurs thermo-fusibles 17, soit l'activa- tion des détecteurs 20 et/ou 35 dont les signaux entraînent
1 'actionnement des vannes motorisées 19 et/ou 33, ainsi que, dans le deuxième mode opératoire évoqué ci-dessus, l'ouverture de la vanne motorisée 27a. L'un et l'autre processus libèrent le liquide extincteur qui est alors projeté sur la ou les zones concernées.In the event of a disaster (fire), the process is much the same as that of already existing fixed installations. Independently of the pressure drop caused in the installation by the fusion of a shutter 17, the information transmitted by other detection and alarm devices are sent to the extinguishing equipment by known means, for example electric, pneumatic or hydraulic. Thus, depending on the triggering mode adopted, the heat given off by the fire hearth causes, in a few seconds and in any case at very short notice, either the melting of the hot-melt shutters 17, or the activation of the detectors 20 and / or 35 whose signals cause 1 actuation of the motorized valves 19 and / or 33, as well as, in the second operating mode mentioned above, the opening of the motorized valve 27a. Both processes release the extinguishing liquid which is then sprayed onto the area or areas concerned.
Dans un processus complémentaire préférentiel, le déclenchement, même localisé des arroseurs 16 entraine, con- currement avec les détecteurs 20, l'actionnement des vannes motorisées 19 créant, au moyen des arroseurs 18 placés sur les ramifications 15a à chaque issue avant et arrière du wagon sinistré, un bouclier thermique de nature à empêcher ou au moins à retarder l'extension éventuelle du feu aux wagons voisins.In a preferential complementary process, the triggering, even localized of the sprinklers 16 causes, concurrently with the detectors 20, the actuation of the motorized valves 19 creating, by means of the sprinklers 18 placed on the branches 15a at each front and rear outlet of the affected car, a heat shield capable of preventing or at least delaying the possible extension of the fire to neighboring wagons.
Des déflecteurs (non représentés) de profil et d'o- rientation adaptés à la configuration du convoi protègent les arroseurs de l'effet de vent en cas de déclenchement du dispositif pendant la marche du convoi.Deflectors (not shown) of profile and orientation adapted to the configuration of the convoy protect the sprinklers from the wind effect in the event of triggering of the device while the convoy is running.
La mise en fonctionnement des moto-surpresseurs 5 AV et/ou 5 AR est automatiquement déclenchée par la baisse de pression consécutive à l'ouverture d'au moins un arroseur 16 ou d'une vanne motorisée 19 et/ou 33 et/ou 27a, de manière à maintenir les arroseurs en action sous pression maximale jusqu'à épuisement de la réserve 2 de liquide extincteur.The putting into operation of the 5 AV and / or 5 AR motor boosters is automatically triggered by the pressure drop following the opening of at least one sprinkler 16 or a motorized valve 19 and / or 33 and / or 27a , so as to keep the sprinklers in action under maximum pressure until the reserve 2 of extinguishing liquid is used up.
Si le convoi transporte des véhicules routiers four- gons à toit ouvrant, de type FI décrit ci-dessus, ledit toit est ouvert à l'embarquement de sorte qu'un feu se déclarant dans le fourgon agisse sur la rangée d'obturateurs thermofusibles 17 placés en toiture du wagon 10.If the convoy is transporting open-top van road vehicles, of the FI type described above, said roof is open for boarding so that a fire breaking out in the van acts on the row of hot-melt shutters 17 placed on the roof of wagon 10.
Si le convoi transporte des véhicules routiers équi- pés d'un réseau particulier du type F2 décrit ci-dessus, ledit réseau est relié, pour la durée du transport, par l'orifice 31 du convoi, au moyen de la canalisation flexible 32 et de raccords dits "symétriques" ou "rapides" équipant ces trois éléments. Un feu se déclarant dans l'enceinte, du fourgon F2 agit sur les détecteurs 35 et déclenche aussitôt l'action des arroseurs ouverts 18.If the convoy transports road vehicles equipped with a particular network of the F2 type described above, said network is connected, for the duration of the transport, by the orifice 31 of the convoy, by means of the flexible pipe 32 and so-called "symmetrical" or "quick" fittings fitted to these three elements. A fire breaking out in the enclosure, of the van F2 acts on the detectors 35 and immediately triggers the action of the open sprinklers 18.
Dans ces deux cas , la mise en action des arroseurs est effective avant même la propagation du feu à l'extérieur des fourgons .
Compte tenu d'une limite de charα;e d'au moins 20 tonnes par essieu et de sa masse à vide, un wagon-citerne- pompe peut embarquer 50 à 60 tonnes de liquide extincteur, soit sensiblement 60 m3 constituant une réserve capable d'alimenter, à titre de comparaison, deux grosses lances d'incendie (20 m3 /h X 2) pendant +/- 90 minutes.In these two cases, the sprinklers are activated before the fire even spreads outside the vans. Taking into account a load limit of at least 20 tonnes per axle and its unladen mass, a tank wagon-pump can take on 50 to 60 tonnes of extinguishing liquid, ie approximately 60 m 3 constituting a reserve capable to supply, for comparison, two large fire hoses (20 m 3 / h X 2) for +/- 90 minutes.
En cas, exceptionnel, d'extension du feu sur la totalité d'un wagon porte-camion d'une surface de plateau d'environ 80 m2, la dite réserve assure, avec un débit de 25 l/m2/min, (+/- 120 m3/h) une autonomie de fonctionnement dit "en déluge" d'une durée d'environ 30 minutes, laissant ainsi le temps suffisant à l'acheminement et à la mise en action de moyens de secours supplémentaires extérieurs au convoi sinistré. II est, par ailleurs, raisonnable d'estimer :In exceptional cases, when the fire spreads over the whole of a lorry wagon with a platform surface of around 80 m 2 , the said reserve ensures, with a flow rate of 25 l / m 2 / min, (+/- 120 m 3 / h) a so-called "deluge" operating autonomy of approximately 30 minutes, thus allowing sufficient time for the routing and activation of additional external emergency means to the stricken convoy. It is, moreover, reasonable to estimate:
- à moins de 1 % du poids total en charge d'un wagon porte- camion l'équipement anti-incendie dudit wagon.- less than 1% of the total laden weight of a truck wagon the fire-fighting equipment of said wagon.
- entre 20 et 50 kw la puissance nécessaire au fonctionnement de chaque moto-pompe.
- between 20 and 50 kW the power necessary for the operation of each motor-pump.
