Definitions

  • the invention relates to an installation which makes it possible to protect, in particular, vehicles such as vans for the transfer of funds, or vehicles of the police force of order, premises or parts of premises such as entrances to banks, as well as as sites such as a building facade or the peripheral zone of a sensitive installation: pylon, radars, etc.
  • the protective installation according to the invention comprises, like the installations currently known, at least one reservoir of active product. , a dispersion assembly of this product using a pressurized gas and a triggering member.
  • the installations which have been used to date are generally equipped with active product tanks which are directly pressurized in order to allow the ejection of this product as soon as the closure valve is opened or when this tank is punched.
  • Certain installations, in particular those of large capacity comprise a cylinder of high pressure gas which communicate via a pressure regulator with the tanks of active product under pressure.
  • pressurized tanks has several disadvantages both in terms of the efficiency of the installation, due to the pressure drop in the tank during operation, unless an additional reserve of high pressure gas is used, that both in terms of safety, due to the need to use a reservoir having a sufficiently high initial pressure, which entails risks of explosion, in particular in the event of an accident or in the event of fire.
  • the object of the present invention is, on the one hand, to improve the efficiency of the installation, in particular in the case of small installations having a long-term operation, and on the other hand to improve job security. eliminating any risk of explosion, and the invention is characterized in that the dispersion assembly is constituted by a compressor whose operation is controlled by the triggering member, and by a disperser which is connected to the product reservoir active by an expulsion pipe and which is connected to the compressor by a pressurizing pipe.
  • the compressor is equipped with an electric motor, which can in particular be supplied with low voltage and drive a centrifugal turbine.
  • the compressor is advantageously connected to at least two dispersers by a network of tubes connected to the outlet of this compressor, a higher power electric compressor being able to directly supply a whole battery of dispersers.
  • the length of the expulsion conduit for the active product is as short as possible, and is advantageously less than the length of the pressurizing tube, each disperser being placed as close as possible to the reservoir of active product, and in operation, the compressor maintaining an overpressure in the network of pipes which is between 1 and 6 bars, overpressures of 0.5 bars being admissible for small installations such as those put in place on motor cars.
  • a temporary closing means such as a solenoid valve, is interposed between the compressor and each disperser, this means being advantageously placed in the vicinity of the reservoir of the active product so that after use the minimum surface area of the installation could have been in contact with the active product, which avoids any rinsing of the installation with decontaminating products and, for the same reasons, each disperser is advantageously placed if not on the tank itself , at least in the vicinity of the active product reservoir.
  • the triggering member comprises a first element for starting the compressor which can be triggered in the event of an alert or as a preventive measure, and at least a second element for opening the closing means temporary pressurizing pipes, the triggering of this second element causing the effective dispersion of the active product.
  • the two elements of the trip member are constituted by two electrical contactors, and advantageously the input of the second opening contactor is connected to the output of the first compressor start-up contactor.
  • the disperser is an air pump whose injector is connected to the compressor, the reservoir of active product being in communication with the ejector of the tube, such a tube allowing a fairly precise metering of the active product.
  • the pressurizing tube comprises a bypass downstream of the temporary closure means, this bypass terminating in the upper part of the reservoir so as to ensure its placing under pressure.
  • the end of the pressurizing pipe opens directly at the bottom of the tank, the upper part of which has an expulsion orifice provided with a diffusing ejector which ensures the dispersion of the active product.
  • the active product is a physiological incapacitant such as a tear product, which can be replaced, in whole or in part, by colored labeling products or by opacifying products, and the invention is particularly suitable for producing a protection unit for a motor vehicle.
  • the electric motor of the compressor is advantageously connected to the terminals of the vehicle battery, one of the conducting wires being equipped with a contactor arranged inside the vehicle cabin, and each means temporary closure of the tubing is controlled by an independent opening element which is also arranged inside the passenger compartment of the vehicle.
  • any pressure tank mounted on a vehicle can be an aggravating cause of accident, especially in the event of a fire causing the tank to explode; in addition, if the pressure tank contains an incapacitating active product, in this case the danger is even greater, even if it is only an accident without fire, because the simple rupture of the pressure tank would risk seriously disturb the injured driver or passengers due to the excessive concentration of active product.
  • the single figure schematically represents in perspective a private car whose protection is ensured by means of an installation making it possible to dissipate at the four angles a tear product.
  • the energy source used is the battery (1) of the vehicle, one of the terminals (2) of which is grounded on the chassis and the other terminal (3) of which is directly connected to the contactor ( 4) for triggering the electric motor (5) which is coupled to the centrifugal compressor (6).
  • This compressor flows into the network of pipes (7), the successive diversions of which lead to the four solenoid valves (8) placed in the vicinity of the tanks (9) of tear powder, the outlet pipes of the solenoid valves entering the tanks and extending up near the bottom of these tanks, the tear product can be entrained in the expulsion conduits which open at the top of the tanks and which end in a flat nozzle, which is normally sealed and which forms a diffuser ejector to wide opening angle used as a disperser (10) for this product.
  • each solenoid valve (8) has one of its terminals connected to ground while the other terminal is connected to the output of the contactor (11) for opening the solenoid valves, the input of this contactor being connected to the portion of the motor control circuit (5) which is between the contactor (4) for triggering the electric motor and this motor itself, the simultaneous opening of the solenoid valves can therefore only be triggered after switching on while the compressor is running, which constitutes additional security.
  • each solenoid valve is controlled by a particular opening contactor which allows a selective dispersion of the tear product which can in particular be orthochlorobenzalmalononitrile (CS) or in very fine powder with a particle size average of 7 to 10 micrometers, or dissolved in a solvent such as a ketone.
  • CS orthochlorobenzalmalononitrile
  • the effective protection of a car can be obtained by using four 0.2 liter tanks connected to four dispersers oriented substantially at 135 0 with respect to the sides of the vehicle, a compressor whose outlet overpressure is 1.5 bars allowing d '' obtain in a second a cloud about 7 meters long by 1.5 meters high and 2.5 meters wide, this cloud can be maintained or renewed by a new push of the contactor (11) for opening the solenoid valves .
