Definitions

  • the invention relates to a missile for fire fighting according to the preamble of claim 1.
  • a so-called fire-extinguishing bomb known from a cylindrical glass or plastic container for receiving a Extinguishing agent and an inner container concentrically arranged therein for receiving of a disintegrant.
  • the ignition of the explosive takes place here by the external heat generated by a fire.
  • the extinguishing agent is not distributed evenly. While in some places extinguished the flames In other places, the fire will have time to spread even more and possibly already deleted areas to set fire again. in the worst case it comes to an increase of the fire thereby, that one certain amount of extinguishing agent hits an object whose position is thereby changed and that in turn puts more objects on fire.
  • DE 195 00 477 C1 discloses a method and a device for deletion known from forest or wildfires. It will be with an extinguishing agent filled, closable at their ends, flexible hoses, with a Explosives are provided, designed in front of a fire front. By the explosive is brought to the ignition, the extinguishing agent mist is generated. This takes place a peripheral fight against the fire. This means that the outer margins a burning area - if this is for a fire-fighting personnel without danger are accessible - can be deleted. An efficient fire fighting can not be made. The areas already on fire may be hindered from further spreading, i. H. be contained. However, what is already inflamed is mostly the destructive effect of the fire exposed to complete destruction and beyond saving.
  • the present invention is based on the technical problem, a To realize missile, which is an efficient fire fighting with a opposite allows the prior art larger area effect.
  • the object of the invention solved by using a missile for firefighting, equipped with an extinguishing agent container on which a disintegrant so is arranged that when blowing up the explosive means of an igniter in the Extinguishing agent container extinguishing agent is released in the form of mist.
  • the invention proceeds in a first step from the knowledge that an efficient Possibility of fire fighting the mist extinguishing process represents. fog has a greater extinguishing effect on liquid. As a result of that generates a relatively large amount of mist from a small amount of liquid has to be in a extinguishing agent container for fog extinction only a small Amount of liquid compared to a fire-extinguishing bomb be included.
  • the invention now starts from the consideration that in a missile only a limited amount of extinguishing agent is transportable.
  • An application of the mist quenching method to that carried by the missile Extinguishing agent therefore means an increase in efficiency in fire fighting compared to the previous fire-fighting bombs, where the extinguishing agent uncontrolled is distributed in large quantities.
  • the extinguishing agent is extinguishing agent to the efficient fire fighting suitable place to bring.
  • the extinguishing agent is defined in the form of fog surface released, which extinguishes the fire quickly and efficiently.
  • Mist is here understood to mean a relatively homogeneous gaseous-liquid mixture, this is usually a droplet size of the liquid of ⁇ 0.1 mm Has. Due to the small size of the droplets in the mist becomes a strong cooling effect achieved because a high thermal bonding is generated. Unlike liquid fog and a pollutant or smoke binding is achieved. moreover becomes more efficient with mist quenching compared to liquid quenching Oxygen displacement achieved. As a result, the extinguishing effect is increased and a allows faster fire containment.
  • each object is understood, via an aircraft or via a mobile or stationary throwing device can be shot down or thrown off.
  • the missile can without drive or with its own drive, such as a propeller, a on the recoil-based drive, etc., be equipped.
  • the extinguishing agent container for fog extinction in a missile can be integrated, an extinguishing agent fog generation in the central area of a Fire for efficient fire fighting done.
  • the one in the case of a design of extinguishing agent containers due to the heat to be maintained distance The fire can be overcome by the missile, for example, by an aircraft or throwing device in the central area of the fire shot or thrown on this. A threat to the fire-fighting personnel and damage to aircraft or throwing equipment caused by fire is prevented because larger distances to the fire can be selected.
  • a Werfer used to launch the missile can these aiming the missile at the location of the fire via sensory Means such as infrared, laser or radar feature.
  • sensory Means such as infrared, laser or radar feature.
  • Such throwers are known from DE 196 01 282 C1 and DE 198 25 614 A1.
  • an extinguishing agent container a filled with extinguishing agent bag used by a grid construction is wrapped.
  • the material of the bag should on the one hand a certain strength have, on the other hand but be brought to bursting in blasting can.
  • a material for example, is a resistant, thin-walled Plastic film.
  • the grid construction may be to trade a metal wire mesh. This is an undamaged transport of the bag and still fog generation through the mesh possible. It makes sense to have the materials for bag and grid construction even a small weight on, so the lightest possible missile can be produced. As a result, for example, due to the reduced weight transported with a plane a larger number of missiles become.
  • the bag can already be filled with extinguishing agent and, for example, by Be sealed welds.
  • the bag can also be closed with a Be provided with filler neck, thus the bag depending on the type of fire or the burning material depending on the situation with the most suitable Extinguishing agent is fillable.
  • the grid construction ideally contains an implementation possibility for the filler neck. Are at one Fire in a chemical plant different substances caught fire, so Often these can not be deleted with the same extinguishing agent.
  • the explosive is in the form of a detonating cord, which extends in the longitudinal direction of the extinguishing agent container. This ensures complete bursting of the bag filled with extinguishing agent and homogeneous mist generation.
  • the bag is designed as a cylindrical roller with a concentric internal passage. Through this internal passage then the detonating cord can be pulled, so that a bursting of the bag over its entire length is guaranteed.
  • the disintegrating agent is designed in the form of discrete explosive charges, which are arranged at defined intervals on the extinguishing agent container. It makes sense that the explosive charges are attached to the bag or extinguishing agent container so that it completely bursts open and produces a homogeneous, large-scale fog front.
  • the missile is equipped with a Zeitzünder so that a Blasting of the extinguishing agent container and associated mist generation at a suitable distance to the place of the fire to obtain a special large extinguishing effect occurs.
  • the time fuse is usefully with a time limit applied, the speed of the missile and distance between missile and fire is determinable. This ensures that the extinguishing agent fog production over the central area of the fire and within the range of the fog takes place.
  • the extinguishing agent container is designed so that more Extinguishing agent can be coupled to these, so with a missile the depending on the size or intensity of the fire to be combated amount of extinguishing agent required is transportable.
  • the missile grows dependent from the number of directly, without spacing behind each other Extinguishing agent tank in the length.
  • the grid structures that with Envelope filled with the extinguishing agent bag, are anchored to each other, the multiplied by a single missile transported amount of extinguishing agent become. For example, in the case of wildfires, a further, rapid spread can occur of the burning area are quickly and effectively suppressed.
  • the blasting agent is carried out over all extinguishing agent container, so that over a single igniter all Extinguishing agent can be brought to demolition.
  • the missile is provided with the flight stabilizing wings.
  • the wings can be completely or on a partial area along the missile extend. Through the wings, the flight characteristics of the missile improved and the desired trajectory can be better adhered to. Of the Missile is thus less sensitive to wind gusts. Achieving the actual central fire area is thus not only relieved, but effectively supported.
  • the missile has its own drive for locomotion.
  • an engine contained in the missile is the missile regardless of the weather-related thermal conditions. Wind or rainfall can not miss the missile due to its own drive dissipate a fire-oriented trajectory.
  • a threat to the Firefighting personnel and the firing or ejection equipment by the fire can be excluded because safety distances from the fire in the kilometer range can lie, as these by a missile with its own drive unproblematic are to be overcome and the missile so to speak self-target, d. H. in the central fire area, brings.
  • missile with its own drive are usually able to perform evasive maneuvers, play obstacles in the area of the trajectory of the missile does not matter. Thus, too geographically difficult to access areas, e.g. Mountainous areas, in the case of a fire quickly and deliberately deleted.
  • Another advantage is the missile with a sensor and a trip unit to provide, over which, depending on a signal from the sensor of the detonator is triggerable.
  • the trip unit without human intervention externally initiable demolition of the extinguishing agent tank play neither Weather-related or due to smoke poor visibility a role. Human wrong decisions, too early or late Ignite the explosives lead and no or only a decentralized deletion from peripheral areas of fires and thus a meaningless loss of a valuable Missiles are completely excluded.
  • the Determining the ignition timing based on a sensor signal causes an increase the extinguishing effectiveness, since an "on-site assessment" via the sensor signal the current fire situation is made.
  • the trip unit is connected to a height sensor, via the height above a fire is determinable. Will a defined distance, the corresponds to a certain signal of the height sensor achieved, it is conveniently automatically via the signal value transmitted to the trip unit a detonator ignition. This is the defined distance skillfully by a distance in the range of the extinguishing agent fog lies to realize an effective fog clearing.
  • Another advantage is the connection of the trip unit with an infrared or heat sensor, with the temperature of objects or a Underground is determinable. Exceeds those by means of the infrared or thermal sensor detected temperature reaches a certain threshold, then the ignition automatically initiated via the trip unit. By triggering the blast only at high temperatures on the trip unit is a meaningless Waste of the extinguishing agent mist in fire areas avoided, too can be deleted via simpler extinguishing means. The fire fighting can also be done in places where the fire rages particularly strong and the danger of enlargement of a source of fire is present.
  • a not so effective, but inexpensive version results in equipment of the missile with a sensor, over at the impact of the missile on an object or the ground the ignition of the explosive device by trip unit is triggerable.
  • the missile has a steering unit for flight guidance.
  • the steering unit has, for example, elevator and rudder and controls about the flight of the missile.
  • the elevator and rudder can in the rear area be arranged of the missile.
  • the steering unit especially To be able to take advantage of good, this is mostly in missiles, the one about own drive, provided.
  • a steerable missile extremely useful. Damage to the missile through collisions with objects before reaching the actual source of the fire is avoided.
  • the steering unit remotely adjustable via radio. The steering unit then allows it due from active influence by the fire-fighting personnel a fire relative to exactly to meet. As a result, the fire can be brought under control very quickly.
  • the missile has a control unit with the steering unit connected and connected to means for target search. This takes place starting from the signal of the means for target search a control of the steering unit via the control unit to the finish.
  • a control of the steering unit via the control unit to the finish.
  • a control of the missile via a line of sight connection in the fire is not possible.
  • This problem can, however by the combination of a control unit with a steering unit in connection be overcome with goal-seeking means. This is a guided missile realized that can automatically fly to a destination without being dropped or missile firing requires another human intervention is.
  • a Global Positioning System GPS
  • the steerable missile Based on the fix before the launch or launch of the missile predetermined target coordinates, the steerable missile by means of his GPS automatically approach the destination without external intervention. This is both a Reaching the source of the fire as well as ensuring protection of the fire-fighting personnel. By such a missile otherwise fire fighting are not accessible Areas such as canyons, valleys, steep slopes or mountains can be opened and effectively quenchable by fog clearing. To the GPS appropriately appropriate exploit, so equipped missile usually also has a own drive.
  • Another advantage is the use of an infrared detector to search for a target, on which an object scene can be mapped via an optic.
  • the via the infrared detector received signals via the control unit to the Steering unit for alignment of the missile transmitted to the fire.
  • the Infrared detector ensures that the missile always in the direction of greatest temperature and thus directed in the direction of the fire. So one effective target search can be performed, the missile is practical equipped with its own drive. Regardless of the visibility the missile independently finds the central fire area. Thereby can the areas most affected by the fire are safe and fast by a deletion with a homogeneous extinguishing agent mist under control brought and protected.
  • the missile may also be equipped with a brake parachute. Thereby the impact of the missile is damped on the ground and the components of the missile protected from damage. This is a recycling components of the missile and at best a reuse of the missile after replacement with extinguishing agent containers possible. Due to the braking parachute brought about reduction of the missile speed is also a more accurate determination of the triggering time in Case of a remotely triggered radio detonator possible.
  • the missile may have over impact protection activated shortly before or after ignition of the explosive device, components, such as the trip unit, the height sensor, the Infrared or thermal sensor, the steering unit, the control unit and the homing Means, from damage and destruction in case of impact of the missile to protect the soil or an object and any eventual recycling to enable.
