Definitions

  • the technical field of the invention is that of devices for extinguishing fires occurring nearby or on a structure or a vehicle.
  • the known means generally comprise extinguishing line pipes as well as diffusers distributed in several zones of the element to be protected.
  • the detection and extinction structure is complex and is permanently fixed in the room or compartment to be protected.
  • the confinement of the space also facilitates extinguishing by smothering the fire with the extinguishing agent.
  • the known devices are therefore either adapted to extinguish a fire inside a structure or are designed to act at a safe distance.
  • the object of the invention is to provide a fire extinguishing device occurring in the vicinity or on a structure (in particular a vehicle), a simple implementation device that does not require in particular the setting up of a network of fire-fighting devices. extinguishing pipes.
  • the subject of the invention is a device for extinguishing fires occurring near or on a structure or a vehicle, a device comprising at least one extinguishing agent and a means of dispersing this agent, characterized in that comprises at least one dispersing tube containing the extinguishing agent, tube also containing a propellant dispersion charge and means for igniting said charge, a piston being interposed between the propellant charge and the extinguishing agent.
  • the tube may comprise at its front part a diffuser ensuring the opening of the cloud of extinguishing agent at the outlet of the tube.
  • the diffuser may include at least three radial arms evenly distributed angularly.
  • the diffuser may include at least one ring coaxial with the tube.
  • the diffuser may comprise a plate pierced with holes.
  • the device may comprise at least one firing base integral with the structure or the vehicle, the base being able to receive the tube via a mechanical attachment interface and also ensuring the initiation of the firing ignition means. .
  • the device may comprise a means for controlling the initiation of the ignition means, which means is manually operable.
  • the initiation control means may be coupled to at least one fire detector and initiate automatic initiation in response to fire detection.
  • the figure 1 shows a disperser tube 1 which carries at its rear part a mechanical interface 2 for attachment to a base (not shown) and which is integral with a structure to be protected (eg a vehicle).
  • a disperser tube 1 which carries at its rear part a mechanical interface 2 for attachment to a base (not shown) and which is integral with a structure to be protected (eg a vehicle).
  • the interface 2 thus carries at least one radial lug 3 and the mounting is performed by a bayonet mechanism, the lug 3 flowing in a groove of the base (can be provided from one to three radial lugs).
  • the interface 2 also comprises an axial bore which encloses a pyrotechnic dispersion charge 4 and an ignition means 5 of this charge.
  • the ignition means may be a percussion device.
  • the ignition means 5 will be an electrical igniter which will be actuated by a contact carried by the base (not shown).
  • Such a tube with a fixing interface containing a dispersion charge is known in the field of armored vehicle defense devices.
  • a tube with a fixing interface containing a dispersion charge is known in the field of armored vehicle defense devices.
  • the tube 1 contains an extinguishing agent 6.
  • This agent will preferably be produced in the form of a powder with extinguishing capacities, for example a potassium bicarbonate or potassium allophonate powder.
  • An extinguishing agent in the form of a gel may also be used.
  • the tube 1 is closed at its front by a plug 7.
  • a piston 8 is interposed between the propellant charge 4 and the extinguishing agent 6.
  • the plug 7 has a certain thickness and is fixed to the tube 1 by at least one radial pin (not shown).
  • Two cylindrical hemi-shells 9a, 9b are interposed between the extinguishing agent 6 and the tube 1. The shells are also supported, on the one hand on the piston 8, and on the other hand on the stopper 7.
  • the figure 2 shows a vehicle 10 which is provided with three bases 11 fixed on the roof 12. Each base 11 can receive a tube 1 disperser according to the invention.
  • the bases are positioned and angularly oriented relative to the vehicle so that the extinguishing agent is propelled towards the area to be protected (here the compartment 13 of the vehicle engine).
  • the bayonet mounting of the tubes 1 on their bases 11 makes it easy to replace a tube used by a new tube.
  • Another type of fastening of the tube on its base for example a thread connection, may be implemented.
  • bases 11 may also receive, depending on operational requirements, other types of tubes performing other functions: masking, decoying, projectile riot projectile, tear.
  • the figure 3 is a block diagram showing schematically the entire device 14 according to the invention.
  • This device comprises a control means 15 which is an electronic box connected to the various bases 11 receiving the dispersing tubes 1.
  • This control means is intended to ensure the initiation of ignition means 5 enclosed in the tube 1 considered.
  • the electronic means will be connected to a push button 16 which will allow manual actuation of the launching tube or tubes.
  • An interface 17 will of course be provided allowing the user to visualize which tubes 1 are available and usable at each base 11: presence of a tube, nature of the tube (extinction or other function).
  • the interface 17 will also make it possible to choose the operating mode used: manual control by the push button 16 or automatic control of one or more tubes 1 in response to a signal provided by one or more fire detectors 18.
  • diffusing means which ensure the fragmentation and dislocation of the block constituted by the extinguishing agent 6.
  • the diffuser means are also useful when the agent is in the form of a gel because they ensure the division and facilitate the dispersion of the gel.
  • FIGS 4 to 8 show different embodiments of the tube 1 and the diffuser means.
  • the figure 4 thus shows a tube 1 which comprises at its front part a diffuser 19 which comprises three radial arms regularly distributed angularly and two rings 21 and 22 coaxial with the tube 1.
  • the figure 5 shows a tube 1 in which the diffuser 19 comprises three radial arms regularly distributed angularly and a median disc 23.
  • the figure 6 shows a tube 1 whose diffuser 19 comprises three radial arms regularly distributed angularly and a single ring 21 coaxial with the tube 1.
  • the figure 7 finally shows a tube in which the diffuser 19 comprises a plate pierced with holes 24.
  • This latter mode is more particularly adapted to an extinguishing agent in a gel form or a liquid form.
  • the diffuser 19 facilitates the dispersion and the opening of the cloud of extinguishing agent 6 at the outlet of the tube 1.
  • the diffuser 19 is fixed by riveting to the body of the tube 1.
  • the figure 8 shows finally a last variant of the invention wherein the tube 1 comprises two parts 1a and 1b of different diameters.
  • the rear portion 1b has a diameter which is adapted to that of the base 11.
  • the front portion has a diameter greater than that of the rear portion 1b.
  • This embodiment makes it possible to define a diffuser tube enclosing a mass of extinguishing agent.
  • the piston 8 is housed in the front portion of the tube.
  • the rear part 1b will contain the propellant dispersion charge.
  • the device according to the invention can equip fixed structures, such as buildings or shelters.
