Abstract

The device has a propeller provided with remotely controllable turbines in three dimensions. An end of an umbilical is integrated to the propeller, and another end of the umbilical is connected to a pressurized water source at ground for fire control. The propeller is driven by an electrical motor. Electrical cables are connected with the electrical motor. The propeller is equipped with an electrical battery to function the propeller in an autonomous mode in an event of cutting the umbilical, where the umbilical is maintained in air by distributing the propeller over its length.

Description

-1-DESCRIPTION. -1-DESCRIPTION.

La présente invention concerne un dispositif de lutte contre les incendies, il est destiné aux pompiers ou organismes chargés d'éteindre ou limiter de développement des incendies. Il existe de nombreux dispositifs terrestres et aériens pour lutter contre les incendies. The present invention relates to a firefighting device, it is intended for firefighters or agencies responsible for extinguishing or limiting the development of fires. There are many terrestrial and aerial devices for fighting fires.

Les dispositifs terrestres sont limités dans l'efficacité de leurs interventions, par les voies d'accès pour les véhicules, et par les difficultés du terrain et les risques liés à l'incendie pour les individus. Les dispositifs aériens sont limités par la disponibilité des aéronefs et parfois les difficultés d'approche des sites (topographie du terrain, lignes électriques..), et la visibilité réduite par les fumées ou l'obscurité de la nuit. Land-based devices are limited in the effectiveness of their interventions, by the access routes for vehicles, and by the difficulties of the terrain and the risks associated with fire for individuals. Aerial devices are limited by the availability of aircraft and sometimes the difficulty of approaching sites (terrain topography, power lines ..), and the visibility reduced by fumes or the darkness of the night.

Ces limitations réduisent l'efficacité d'intervention des pompiers qui ne peuvent pas toujours approcher des lieux les plus appropriés à la lutte contre le foyer de l'incendie. Le dispositif selon l'invention est composé d'une lance à eau déployée, dans l'air, et à distance, par un propulseur à turbine (s) qui le maintient dans l'air et peut déplacer son extrémité dans les trois dimensions suivant le besoin des utilisateurs. L'autre extrémité est 15 connectée à une réserve d'eau sous pression située au sol. Le principal avantage du dispositif est que les utilisateurs peuvent intervenir par la voie des airs sur des foyers distants d'un point accessible par véhicule, il est particulièrement adapté aux sites infranchissables du type falaise, ravin, voie d'eau, végétation dense, clôtures, immeubles.. etc. 20 Le dispositif est composé des éléments suivants Une lance à eau ou ombilical monté sur emmagasineur. L'ombilical dont l'extrémité est fixée au propulseur à turbine se déroule lorsque le propulseur s'élève dans l'air Le propulseur est composé d'une ou plusieurs turbines à hélice(s) horizontale(s) capables de tirer l'ombilical dans l'air. L'entrainement des hélices est réalisé soit 25 par un ou plusieurs moteurs électriques, soit par un ou plusieurs moteurs thermiques. Dans le cas de la motorisation électrique, l'alimentation des moteurs de propulsion est faite par des câbles électriques solidaires de la conduite d'eau (disposés à l'intérieur, ce qui favorise le refroidissement, ou intégré à l'enveloppe, ou fixé à l'extérieur). 30 L'intérêt de la propulsion électrique est son rapport poids/puissance qui est plus favorable qu'une propulsion thermique qui devrait emporter sa réserve de carburant. Par ailleurs l'eau utilisée permet de refroidir les conducteurs électriques, ainsi que les moteurs, ce qui permet d'accroitre la charge utile. Une console de pilotage qui permet à l'opérateur de diriger la turbine vers le foyer à 35 combattre et d'orienter le jet d'eau. La transmission entre la console et le propulseur peut être réalisée par transmission filaire intégrée à l'ombilical (optique ou cuivre) ou transmission radio. L'intérêt d'une solution radio est l'autonomie du dispositif, en effet en cas de coupure de l'ombilical un dispositif de largage de l'ombilical et une faible réserve électrique permettrait de ramener le propulseur hors 40 de la zone d'incendie. De plus cette solution permet à l'opérateur de rechercher la position offrant la meilleure visibilité. Un support roulant (véhicule ou remorque) qui supporte les éléments ci-dessus Afin d'augmenter la distance d'intervention l'extrémité fixe de l'ombilical peut être montée sur un mât rétractable solidaire du support roulant. 45 Un générateur électrique (groupe électrogène ou autre source d'électricité) qui alimente le dispositif en énergie 5 2948880 -2- These limitations reduce the response efficiency of firefighters who may not always be able to approach the most appropriate places to fight the outbreak of the fire. The device according to the invention is composed of a water lance deployed in air and at a distance by a turbine propeller (s) which holds it in the air and can move its end in the following three dimensions. the need of the users. The other end is connected to a pressurized water supply located on the ground. The main advantage of the device is that users can intervene by air on fireplaces distant from an accessible point by vehicle, it is particularly suitable for impassable sites such as cliff, ravine, waterway, dense vegetation, fences , buildings .. etc. The device is composed of the following elements: A water lance or umbilical mounted on a furler. The umbilical whose end is attached to the turbine thruster occurs when the thruster rises into the air The thruster is composed of one or more turbines with horizontal propeller (s) capable of pulling the umbilical in the air. The drive of the propellers is carried out either by one or more electric motors or by one or more heat engines. In the case of the electric motor, the power of the propulsion engines is made by electric cables integral with the water pipe (arranged inside, which promotes cooling, or integrated in the envelope, or fixed outside). The advantage of electric propulsion is its weight / power ratio which is more favorable than a thermal propulsion which should carry its fuel reserve. Moreover, the water used makes it possible to cool the electrical conductors, as well as the motors, which makes it possible to increase the payload. A steering console that allows the operator to direct the turbine towards the firebox to fight and direct the water jet. The transmission between the console and the thruster can be achieved by wire transmission integrated into the umbilical (optical or copper) or radio transmission. The advantage of a radio solution is the autonomy of the device, indeed in case of cutting the umbilical umbilical release device and a low power reserve would bring the thruster out of the 40 zone. fire. In addition, this solution allows the operator to search for the position with the best visibility. A rolling support (vehicle or trailer) that supports the above elements In order to increase the intervention distance the fixed end of the umbilical can be mounted on a retractable mast secured to the rolling support. 45 An electric generator (generating set or other source of electricity) which supplies the device with energy 5 2948880 -2-

Une réserve d'eau externe qui alimente le dispositif en eau. Cette réserve peut être une citerne associée à une motopompe. Le dispositif peut être composé d'un ou plusieurs propulseurs, qui sont utilisés comme relais aériens disposés à intervalles réguliers afin de déporter l'extrémité de l'ombilical à une grande distance du support roulant. Dans ce dernier cas chaque propulseur est piloté individuellement. Une ou plusieurs caméras, ou autres capteurs de mesure de position et d'environnement, situés sur les propulseurs, et transmis à la console de pilotage par la transmission retenus, permettent à l'opérateur de se situer par rapport à l'objectif et de manoeuvrer sans visibilité directe. 5 10 An external water supply that supplies the device with water. This reserve can be a tank associated with a motor pump. The device can be composed of one or more thrusters, which are used as aerial relays arranged at regular intervals to deport the end of the umbilical at a great distance from the rolling medium. In the latter case each thruster is driven individually. One or more cameras, or other sensors for measuring position and environment, located on the thrusters, and transmitted to the control console by the retained transmission, allow the operator to be located in relation to the objective and to to maneuver without direct sight. 5 10
