Description

Mobile Fire Extinguishing Device
Field of the Invention
The invention concerns the field of fire extinguishing technology, especially the fire extinguishing technology used for difficult to access properties with limited ground access, such as tall buildings, forest or mountain properties and so forth.
Background of the Invention
As of present, extinguishing in premises with limited access, for example high-rise buildings, individual difficult-access buildings located in non-urban areas or even during forest fires, stationary or mobile fire-extinguishing equipment is used, including aerial equipment used in the case of extensive forest fires. However, the aerial equipment used during extensive forest fires, especially the bulky water bags which drop water during flybys performed by a plane or helicopter, over the extensive fires cannot be used on a large number of high-rise building fires and the accessible, installed stationary fire-extinguishing apparatuses meant for the liquidation of fires have a limited effectiveness and thus, many are insufficient. In addition, installed, stationary fire-extinguishing equipment secures only a building's interior area in most cases, whereas it is commonly necessary with most cases that the fire on the outer facade also needs to be extinguished, without which the fire will spread.
New fire-extinguishing equipment using efficient water fog extinguishing, which has a high thermal effect, low water consumption, reduced pipe size, and low overall system weight, is also used for fire fighting in these buildings with limited ground access to fire extinguishing equipment. However, its disadvantage can be found in the fact that this technology uses water as a fire-extinguishing medium and it is impossible to use this technology especially when extinguishing an electrical fire.
Another well-known solution for liquidating fires in objects with limited ground access to fire-extinguishing equipment that is useful even on electrical fires, and that being in both open and closed spaces, is the so-called“anti-fire grenade”. Plastic“anti-fire grenades” that contain an active fire-extinguishing agent are suitable for the centre of a fire or when used on a solid surface above the centre of the fire where the grenade bursts and liquid is released onto the burning surface. The active agent immediately cools the burning surface to a mere 3°C upon release and then, by means of a chemical and physical reaction quite harmless toward people, animals and the environment, the grenade creates a protective layer which completely quenches the fire and prevents any possible reignition. This fire-extinguishing medium is capable of extinguishing a fire in about 10 seconds without seriously damaging or destroying the subjects found within the protected space. The fire-extinguishing liquid used simultaneously absorbs the toxic gases formed by the fire, allowing any persons involved with the fire or its space or those who are onsite for the purpose of extinguishing the fire to breath normally. Anti-fire“hand grenades” used to extinguish fires are suitable as a fire-extinguishing medium which can be used in homes, offices, storage facilities, workshops, vehicles and water vessels. Also, professional fire fighters often use these grenades in their work, especially in extinguishing fires that are difficult to extinguish with water, foams and bursting mediums or by the means of other classic approaches, or if there are subjects of particular value to be found in the area of the fire, for example, works of art, documents, antiques, computers and the like.
A particular disadvantage of these current solutions is the fact that in the core of these solutions, they do not enable quick, precise and effective fire extinguishing, especially in tall buildings and properties with limited ground access.
Summary of the Invention
The object of the presented invention is as a highly mobile device meant for quick, precise and effective fire extinguishing, especially in tall buildings and properties with limited ground access.
The object stated above is achieved via the use of a mobile fire extinguishing device according to the present invention consisting of a remote controlled propeller aircraft drone, equipped with an autonomous camera system, a guidance system and a positioning system for stabilizing the device during the application of extinguishing agents, and a fire-extinguishing device within itself, characterized in that the propeller aircraft drone fitted with an aerodynamic fairing providing protection for the moving parts, an aircraft drone propeller, preferably made of composite carbon materials and powered by four to eight electric motors pertaining to the propellers, and in one of the preferred embodiments, provided with an additional small gasoline engine and an alternator for recharging the aircraft drone's batteries to extend the operating time. The device it is equipped with a thrower of the extinguishing media based on the principle of crossbow or bow inside the aerodynamic fairing, and with an independent missile throwing device meant for piercing the facade of a building with structural glazing and thereby creating an opening in such a glass cased building to allow the use of an extinguishing agent, preferably a gas-operated grenade launcher for firing projectiles, equipped with a magazine fit for these projectiles, and other control and auxiliary elements meant for the operation of the propeller-aircraft drone. The extinguishing agent throwing device based on the principle of the crossbow or bow comprises of a horizontally oriented crossbow bow, preferably made of a composite material, provided at each of the open ends with at least one pulley meant for depositing the chord, at least one simple crossbow chord, at least one fire-extinguishing projectile magazine, preferably two around the longitudinal axes parallel to the main axis of the bow crossbow or bow of the rotating drum magazines arranged symmetrically to the main axis of the bow next to each other and rotating alternately against each other, each projecting drum rotating releasing the projectile alternately into the carrier to direct the projectile down the barrel, connected with the chord crossbow or bow equipped with an electromagnetic lock with a latch, mainly a crossbow for directing fire-extinguishing projectiles containing a fire extinguishing agent into a fire, a winch formed by a pulley and a winding drum for stretching the chord rope, profile rails for spring connection, a spring to tighten and release the chord for firing fire-extinguishing projectiles driven by an electromagnet, a chord rope equipped with an electromagnet coupled to the chord, driving engine of the device with the alternator and at least two symmetrically arranged batteries housed inside the fairing, providing energy for all of the device’s activities, including the air drone. The extinguishing agent throwing device is simultaneously adapted for firing anti-fire grenades containing an extinguishing agent and/or for the use of a technology which forms liquid mist (the technology being ultra fog), when the chord of the crossbow or bow tightens with the help of the tightening rope, through the winch of the winding mechanism and connected to the chord with the help of the electromagnetic lock via the latch is maximally tightened, it is released and the tensioned chord with the carrier attached and the fire-extinguishing projectile placed in it detaches from the rope and ejects the fire-extinguishing projectile, which is directionally guided by the barrel; further, there is a vertically situated lock pick attached on the tightening rope behind the electromagnetic bolt which slides in the groove of the profile bar and then is a tension spring attached to this lock pick, which helps to pull the rope to the starting position after firing, when the winding device begins to release the tension rope after firing, and the tension rope returns to the starting position so that the tension rope may connect with the bowstring or bow once more, in order for the entire cycle to be repeated. To increase the effectiveness of the device within its preferred embodiment, the aerodynamic fairing of the aerial drone located on the outer sections of the aerial drone is fitted with auxiliary, connecting components for the connection of other fire-extinguishing mediums which increase the effectiveness of this device, especially fire-extinguishing containers carrying highly effective fire extinguishing agents, preferably deposited to the adapted carrier, which carries the fire-extinguishing containers.
The mobile fire extinguishing device enables for the effective, pilotless execution of fire-extinguishing strikes in inaccessible areas, from the outer casing of tall buildings and the like. The extinguishing agent used in this procedure will enable the quick localization of a fire.
