Description

Foldable emergency fire extinguishing system {EMERGENCY FIRE EXTINGUISHER DESIGNED TO BE STRETCHED AND FOLDED}

The present invention relates to a foldable emergency fire extinguishing device, and more particularly, to a foldable emergency fire extinguishing device that can be folded and stored in one space and used in an open state in case of a fire to quickly extinguish fire at the beginning of a fire. .

Firefighting systems currently extinguishing fires can be largely classified into water system and gas system.

Here, the water-based fire fighting system is a system that uses a liquid in which an extinguishing agent is dissolved, causing inevitable inundation of the fire occurrence place and objects, which is accompanied by secondary damage that is difficult to restore, that is, water damage. There is a risk due to energization between water and electric wiring, and there is a problem that application is limited in the case of an electric fire. In addition, the water system such as a fire hydrant loses its firefighting function when a freeze occurs due to a cold wave, as well as a problem of increasing maintenance and management costs due to damage to a pipe.

On the other hand, gas-based firefighting systems are generally made to spray nitrogen, carbon dioxide, or halogen compound gas into the fire place, so there is a concern that human damage may occur due to suffocation, as well as sensors, high-pressure facilities, various pipes, valves, and Since a control unit or the like is required, there is a problem that high cost is required to implement a fire fighting system, and the risk of explosion remains.

In particular, in the case of a carbon dioxide firefighting system, sufficient safety measures are required to prevent suffocation caused by the emission of carbon dioxide caused by use in the installation area, so in the event of a fire, a voice alarm or a siren is sounded to ensure personnel evacuation and The system is operated by manipulation, or carbon dioxide is injected after announcing this through a voice alarm or siren with a time allowance for sufficient evacuation of personnel in the fire area.

Among these prior art, Korean Patent Application Publication No. 10-2013-0053355 (published date: May 23, 2013) establishes a technology for a fire extinguishing facility in a submarine engine room.

However, in the case of the above carbon dioxide firefighting system, damage due to fire may be increased because initial extinguishing may not occur quickly while checking whether personnel are evacuated.If the entire installation area is operated even in a small fire, it is extinguished. The operation becomes inefficient, and on the other hand, if it is implemented so that the initial extinguishing occurs quickly without checking whether or not personnel are evacuated, it becomes a problem in that personal injury due to suffocation may occur.

Therefore, there is no risk of suffocation due to the use of fire extinguishing gases such as carbon dioxide, and unlike non-floor powder fire extinguishers that have difficulty in use by the elderly, etc., initial extinguishing is carried out quickly and easily regardless of age or sex at the beginning of the fire. There is a need for simple firefighting devices or tools that can be done.

First, the support flesh 110 is a component that variably forms an extinguishing space (ES) therein through elastic deformation and becomes a skeleton that forms the basic shape of the foldable emergency fire extinguishing device 100 according to the present invention, and is elastically deformed. The shape or structure is not particularly limited as long as it is a structure that can be folded into a thin thickness or a small volume, and can form a predetermined extinguishing space (ES) inside when elastically restored.

However, as shown in Figs. 1 to 3, the support ribs 110 according to the embodiment of the present invention are formed of a plurality of elastic rods that are arranged and coupled radially with respect to the central gripping unit 112 to be elastically deformed. I can.

The central gripping part 112 is a component provided to allow the user to hold the emergency fire extinguishing device 100 according to the present invention by hand in the event of a fire and to easily move or withdraw the emergency fire extinguishing device 100 from the mounting box 150 to be described later. Can be made with

The support flesh 110 may be manufactured by molding a high-elastic synthetic resin using silica (silicon oxide) or glass fiber having excellent heat resistance as a reinforcing material (core) into a rod shape.

At this time, the central gripping part 112 and the support ribs 110 are manufactured separately and then a method of combining the support ribs 110 along the circumference of the central gripping part 112 or a highly elastic synthetic resin containing glass fibers, etc. It may be integrated by molding a plurality of support ribs 110 and the central gripping portion 112 together as a material.

As described above, when the plurality of rod-shaped support ribs 110 integrated with the central gripping part 112 are elastically restored and unfolded based on the center gripping part 112, they form an umbrella-shaped skeleton that is convex upward as a whole, and inside Evolutionary space (ES) is formed.

Can be easily inserted and stored in the holder 150 having an opening formed thereon.

Here, the mounting box 150 is provided or installed at corners inside and outside the structure, around the entrances, and on the wall 10, and can be conveniently stored and used by easily drawing out the emergency fire extinguishing device 100 according to the present invention, which is compactly folded. It is an additional component prepared to enable it.

On the other hand, the foldable emergency fire extinguishing device 100 ′ according to a modified example of the present invention, as shown in Figs. 4 and 5, is a support flesh 110 ′ composed of a coil-shaped spring that is wound in a spiral shape and elastically deformed. Can be replaced with

Such coil-shaped support ribs (110 ′) may be formed in the shape of a prismatic, cylindrical, or elliptical, but can be folded into a more flat shape and a cone shape whose width narrows upwards for a balanced seating on the ground. It is preferable to be manufactured in the shape of a pyramid, cone or elliptical cone.

The coil-shaped support ribs 110 ′, like the rod-shaped support ribs 110 described above, may be made of a material such as glass fiber having excellent resistance to the flame 20, that is, heat resistance and elasticity. When elasticity is restored by not being applied, it forms a shape that protrudes upward as a whole and forms an evolution space (ES) inside.

On the other hand, when the coil-shaped support flesh 110 ′ is elastically deformed and folded by an external force, the emergency fire extinguishing device 100 ′ according to the present invention has a slit-shaped opening at the upper side as it is deformed into a compact plate shape. It can be easily inserted and stored in the formed holder 150, or can be conveniently provided in a narrow gap inside and outside the structure, the wall surface 10, etc., and can be easily taken out and used in case of fire.

Components other than constituting the emergency fire extinguishing apparatus 100 ′ according to the modified example of the present invention perform the same functions and actions as in the embodiment, and thus a description thereof will be omitted.

The flame-retardant sheet 120 is a component provided to form an extinguishing space (ES) that blocks the spread of fire together with the aforementioned support ribs 110 and 110 ′, such as silica (silicon oxide) or glass fiber that does not burn. It can be made of sheets containing the same fire-resistant material.

The flame-retardant sheet 120 according to an embodiment of the present invention may be made of a commercially available sheet in the form of a fabric or film having a thickness of approximately 0.3mm to 5mm, which can be freely folded or unfolded and is easy to handle by a user.

This flame-retardant sheet 120 is cut in a shape corresponding to the overall shape of the elastically restored support ribs 110 and 110 ′, respectively, as shown in FIGS. 1 and 4, and then coupled to the support ribs 110 and 110 ′, An extinguishing space (ES) that can be shielded can be formed inside the emergency fire extinguishing devices 100 and 100 ′ according to the present invention.

At this time, bonding of the flame-retardant sheet 120 cut into a required shape to the support ribs 110 and 110 ′ may be achieved by adhesion using an adhesive material, lockstitching using thread, or heat fusion using surface friction.

The flame-retardant sheet 120, each coupled to the support ribs 110 and 110 ′ according to the embodiment or modification in the above manner, is accommodated in a folded state according to the elastic deformation of the support ribs 110 and 110 ′, etc. Then, in the event of a fire, it expands in tension according to the elastic restoration of the rod-shaped or coil-shaped support ribs (110, 110 ′) to form a convex umbrella-shaped or cylindrical (conical)-shaped extinguishing space (ES).

As described above, if the extinguishing space (ES) formed by the tightly spread flame retardant sheet 120 is quickly positioned at the ignition point, the flame retardant sheet 120 effectively prevents the spread of the flame 20, and external oxygen The inflow of the flame 20 is suffocated by suffocating the flame 20, and as the outflow of the extinguishing material 132 to be described later is reduced, safe and rapid initial extinguishing can be achieved without the risk of suffocation.

However, the combustible sheet 130 according to an embodiment of the present invention may be a flash paper that suddenly ignites and disappears when a fire is approached.

Here, the flash paper maintains the shape of a sheet while heat is not applied and suppresses the outflow of the extinguishing material 132 accommodated in the inner pocket, but refers to a chemically treated paper that ignites and disappears without a trace when it approaches the heat.

These flash papers can be prepared by nitrating by dipping 100% cotton paper in a mixed acid of nitric acid and sulfuric acid in the same ratio to nitrate, and then gradually sublimating and drying by removing acid radicals.For safe use, examples of the present invention It is preferable to use a commercially available product having a moisture content of 20% in etc.

Extinguishing material 132 according to an embodiment of the present invention is a powder fire extinguishing agent comprising at least one of sodium bicarbonate, potassium bicarbonate, phosphate, sulfate and other flame retardant salts that react with fire to cause thermal decomposition and extinguish a fire. As an example, it can be classified into 1 type powder (NaHCO3), 2 types powder (KHCO3), 3 types powder (NH4H2PO4), and 4 types powder (KC2N2H3O3).

The extinguishing action at this time refers to an extinguishing action performed by asphyxiation or cooling by a material generated by a pyrolysis reaction with the flame 20.

On the other hand, the extinguishing material 132 may be a halogen compound extinguishing agent such as Haron 1211, Haron 1301, HCFC Blend A, HFC-227ea, etc., which can be applied to electrical facilities, substations, communication rooms, computer rooms, aircraft, etc., in addition to the above-mentioned materials. have.

As described above, the flammable sheet 130 made of flash paper is immediately ignited as soon as the flame 20 is shielded (suffocated) in the extinguishing space (ES) by the user and quickly depletes oxygen in the extinguishing space (ES). , The fire extinguishing material 132 in the pocket acts to be quickly dropped into the flame (20).

Due to this, the fire shielded in the extinguishing space (ES) can be extinguished more reliably and quickly by the superimposed and sequential first and second extinguishing action by the extinguishing space (ES) and flash paper.

The combustible tube 140, as described above, performs an additional fire extinguishing action together with the extinguishing space (ES) shielded by the flame retardant sheet 120 and the combustible sheet 130 accommodating the extinguishing material 132, while performing an ignition point The emergency fire extinguishing apparatus 100 according to the present invention positioned so as to cover it is a component that performs the role of a heavy object so as not to deviate from its position due to hot air or external force caused by a fire.

The combustible tube 140 according to an embodiment of the present invention, as shown in FIG. 3, is composed of a soft tube provided along the lower circumference of the flame retardant sheet 120 in a state containing the digestive fluid 142 therein. Can be.
