Description

FIREFIGHTING SYSTEMS USING FLAME RETARDANT FABRIC THAT IS UNFOLDING FIELD OF THE INVENTION [0001]

FIELD OF THE INVENTION The present invention relates to a firefighting system using a flame retardant cloth, and more particularly, to a firefighting system in which a flame-retardant cloth is horizontally expanded from a ceiling of a flame-retardant indoor space,

Currently, fire fighting systems that evolve fire can be classified into water system and gas system.

Here, the water-based fire-fighting system is a liquid in which fire-extinguishing agents are dissolved, and inevitably submerges fire-generating places and objects. Therefore, it is common to carry secondary damages that can not be restored, There is a risk of electric current flowing between the electric wire and the electric wire, and there is a problem that application is limited in the case of electric fire. In addition, a water system such as a hydrant has a problem in that, when a frost wave occurs due to cold waves in the winter, the fire-fighting function is lost, and maintenance costs are increased due to pipe breakage or the like.

On the other hand, gas-based fire-fighting systems are generally designed to spray nitrogen, carbon dioxide, or halogen compound gas to the fire site, which may cause personal injury due to suffocation. Since high-pressure equipment and various piping are required, There is a problem that the cost is high and the risk of explosion remains.

In order to supplement the disadvantages of such water and gas fire fighting systems and to prevent the fire from spreading, Korean Utility Model Registration No. 20-0411905 (Publication Date: March 21, 2006) This invention proposes an invention for a flame spread interrupting device in the event of an apartment fire which can minimize the damage of people and damage property by securing the initial evolution time by delaying the diffusion to other generations as much as possible.

That is, the above-described prior art is characterized in that a case having a flame-retarding film installed in a ceiling of an inner side of a window glass and capable of falling downward is formed, and the case is supported in a lower portion of the case so as to allow the flame- A weight member is provided at one end of the heat collecting plate so that the heat collecting plate may be separated when the heat collecting plate is separated.

However, this prior art has a problem in that the problems arising from the water-based and gas-based fire-fighting systems are solved, but the use of the flame-proof shield is not the purpose of the fire itself or the fire, There are basically limitations on the application in terms of devising.

Therefore, it is necessary to utilize the flame-retardant cloth or flame-retarding barrier which can exert the fire-fighting function reliably while eliminating the disadvantages of the water-based and gas-based fire-fighting systems.

Korea Registered Utility Model No. 20-0411905 (Date of Publication: March 21, 2006)

(Upper), lower (lower), left and right (sideways or laterally), front (front), rear (rear), etc. referring to directions in the description of the invention and the claims are based on the drawings , And each direction described below is based on this, except where otherwise specifically limited.

The fire fighting system 100 using the deploying type flame retardant cloth according to the present invention is configured such that the deploying flame retardant cloth 110 in a normally folded state is deployed horizontally from the ceiling when a fire occurs, The invention, which was devised to eliminate the risk of suffocation or suffocation, which is a disadvantage of the conventional fire fighting system, is fundamentally prevented because it is evolved by a new method completely different from the conventional water system and gas- Thus, there is no limitation in the place where the application is made, and the fire can be rapidly evolved.

In particular, with respect to the place of application, the fire-fighting system 100 using the deploying flame-retarding cloth according to the present invention can be applied to the indoor space 10 at various places, but when the flame retardant cloth 110 falls from the ceiling, The flame retardant cloth 110 is prevented from being applied to the complicatedly arranged indoor space 10 and the opened space of the indoor space 10 is reduced. And the like.

In order to smoothly implement the above-described functions or operations, the fire fighting system 100 using the deploying flame retardant cloth according to the present invention includes a flame retardant cloth 110, a fire detection sensor 120, a gas supply unit 130, (140), and the like.

The deployable flame retardant cloth 110 is installed in a state of being folded on the ceiling of the indoor space 10 at normal times and spreads out in a horizontal direction in the case of fire and is made of a refractory material and is made of silica Fiber, and the like, and can be cut into various shapes and sizes to be used for fire evolution in a specific region, and a development tube 112 into which gas can flow can be formed inside .

The shape of the deployable flame retardant cloth 110 according to the embodiment of the present invention is formed in a shape corresponding to the bottom surface shape of the indoor space 10 in which the fire fighting system 100 is installed, ) In order to ensure complete succulent digestion. A rim 114 may further be formed at the edge of the deployable flame retardant cloth 110 so that the overall size of the full flame retardant cloth 110 is larger than the width of the bottom surface, This is to completely suffocate even the area.

The discharge type flame retardant cloth 110 according to the present invention uses a flame retardant cloth having a thickness of approximately 0.3 mm to 6 mm so that it can be folded in a compact form without difficulty and can be installed on a ceiling, Anything is acceptable. The flame-retardant cloth is already known in the market by being manufactured in various materials and thicknesses, and a detailed description thereof will be omitted.

The expansion tube 112 is a component provided to allow the expansion type flame retardant cloth 110 to be flattened or folded, and is a core of the technical idea of the present invention. And a gas receiving hole 112a is formed therein to expand and contract as the gas flows in and out.

When the expansion tube 112 is inflated with the inflow of the gas, the expansion type flame retardant cloth 110 is flattened along the forming line of the expansion tube 112. When the expansion tube 112 is contracted The flame retardant fabric 110 can be folded freely.

The formation of the expansion tube 112 can be done in various ways, but can be accomplished by mutual adhesion of the two flame retardant fabrics while preventing the formation line portion of the development tube 112 from adhering. At this time, the expansion tube 112 may be made by adhering a heat-resistant elastic material tube between the two flame-retardant fabrics in order to maintain the airtightness more reliably.

The shape of the expansion tube 112 may be any shape as long as the expansion type flame retardant cloth 110 in a folded state can be spread according to inflow of the gas. That is, it can be manufactured in various forms such as a spiral shape, an edge shape formed along the edge of the flame retardant cloth, or a zigzag shape.

However, as shown in FIG. 2, the expansion tube 112 according to the embodiment of the present invention may be configured such that the discharge type flame retardant fabric 110 in a folded state is more smoothly and swiftly spread as the gas is introduced, And is arranged in an X-shape within the fabric 110. The X-shaped extension tube 112 is shorter than any other length of the formation line of the expansion tube 112, so that the quick release operation can be performed, and the gas can be balanced right and left through the central part of the X- So that stable unfolding operation can be performed.

As shown in FIGS. 2 and 3, the expansion tube 112 includes a connection portion 111, a fastening protrusion 111a, and a one-way valve 113. At this time, the connection part 111 and the fastening protrusion 111a are constituent elements provided for rigid coupling with the gas supply part 130, which will be described later.

The one-way valve 113 is a valve formed to prevent the gas supplied from the gas supply unit 130 from flowing only toward the gas accommodation hole 112a and flowing out toward the gas supply unit 130. This one-way valve prevents the connection portion 111 and the gas supply pipe 134 from being separated from each other due to a strong internal pressure generated after the gas accommodation hole 112a in the expansion tube 112 is fully filled with gas, As the outflow is prevented, the deploying flame retardant cloth 110 can keep falling down to the bottom surface.

The unidirectional valve 113 shown in FIG. 3 is elastically deformed with respect to the gas supplied to the gas accommodation hole 112a so that the gas can flow into the gas receiving hole 112a. However, when the gas flows in the reverse direction, the elastic deformation is prevented, Way valve 113 is only one example. If it is possible to withstand the gas pressure in the full-bore gas receiving hole 112a and to prevent the outflow of the gas, the one-way valve 113 It may be used.

2, an unfolded flame retardant fabric 110 is laid in one area of the unfolded flame retardant fabric 110 where the unfolded tube 112 is not formed, The air flow cut-out portion 116 is cut into an arc shape. The air flow cut-off portion 116 may have a shape different from that shown in Fig. 2 as long as the incision portion of the development-type flame retardant cloth 110 falls and the lower air can flow upward.

The injection nozzle 118 is a constituent element provided so that the gas introduced into the inside of the expansion tube 112 is discharged gradually toward the lower side by the internal pressure, Respectively.

The injection nozzle 118 is provided to allow the deployed flame retardant cloth 110 to be dropped at a gentle speed without being deflected to either side while maintaining the horizontal direction.

When the gas introduced into the expansion tube 112 and progressively discharged downward is a fire extinguishing gas such as carbon dioxide, nitrogen, or a halogen compound gas, the fire extinguishing fire extinguishing gas So that the gas-based fire extinguishing by the injection nozzle 118 can be prevented. As the gas-based fire extinguishing by the spraying nozzle 118 and the subsequent fire are superimposed on the fire extinguishing fabric 110 itself by the development-type flame retarding cloth 110 itself, more complete fire evolution can be achieved.

The injection nozzle 118 may be implemented in the form of a one-way valve 113 as shown in FIG. 3 so that the gas introduced into the expansion tube 112 is gradually discharged only to the outside.

The flame retardant fabrics 110 described above can be folded on the ceiling by bundling them with a strap which is folded back and forth at a certain interval on the basis of the connecting portion 111 and broken at the time of unfolding operation, It may be installed in a folded state on the ceiling by an opening / closing door that is folded into a separately formed storage box and broken down in a spreading operation and opened downward.

The fire detection sensor 120 is a type of a thermal sensor that generates an electrical signal when a high temperature heat is sensed for a predetermined time interval and sends the electrical signal to a control unit 140, At least one side is provided.

At this time, the number and location of the fire detection sensors 120 are determined in consideration of the size of the indoor space 10 and the number and location of areas where fire prevention is important. When two or more fire detection sensors 120 are installed and operated, the errors of the fire fighting system 100 according to the present invention can be greatly reduced as the fire is cross-detected

The fire detection sensor 120 is manufactured in various types and forms such as a differential type, a constant temperature type, and a photoelectric type and corresponds to a known technology on the market, so that a detailed description thereof will be omitted.

The gas supply unit 130 is a component that is connected to the expansion tube 112 to provide a gas to the expansion tube 112 to enable the expansion operation of the expansion tube 112. The gas supply unit 130 includes an electric control unit And the gas can be generated and provided through the gas supply pipe.

However, the gas supply unit 130 according to the present invention can be specifically embodied by being divided into the first embodiment and the second embodiment.

First, a gas supply unit 130 according to the first embodiment of the present invention includes an approximately high-pressure vessel 132, a gas supply piping 134, and a high-pressure vessel 134, as shown in FIGS. 1 to 4, A solenoid valve 136, and the like.

The high pressure vessel 132 is a component for accommodating the gas to be introduced into the gas accommodation hole 112a of the expansion tube 112 in a high pressure state. Lt; / RTI > In this case, the gas filled in the high-pressure vessel 132 is not limited to the general air, and if a plurality of the injection nozzles 118 are formed below the expansion tube 112 as described above, the gases such as carbon dioxide, Or a halogen compound gas. The reason is as described above.

One end of the gas supply pipe 134 is connected to the high-pressure vessel 132 and the other end of the gas supply pipe 134 is installed on one side of the ceiling of the indoor space 10,

3, the gas supply pipe 134 and the deployment type flame retardant cloth 110 are connected to each other through the central portion of the X-shaped extension tube 112, communicating with the gas accommodation hole 112a, And the other end of the gas supply pipe 134 is engaged with the connection groove 111 formed on the outer circumferential surface of the other end of the gas supply pipe 134, The fastening protrusion 111a protruding along the inner circumferential surface is tightly engaged with the fastening protrusion 111a so that the fastening protrusion 111a can be formed at a predetermined position.

In this case, the predetermined tightening force is a force that is greater than the internal pressure (resistance) generated inside the expansion tube 112 in the process of unfolding the deployed flame retardant cloth 110 in the folded state by the gas injected through the gas supply unit 130, Refers to a clamping force smaller than a strong withstand pressure generated after the gas receiving hole 112a in the expansion tube 112 is fully filled with gas. The connecting portion 111 and the gas supply pipe 134 maintain a firm connection in the process of expanding the discharge flame retardant cloth 110 and the gas receiving hole 112a in the expansion tube 112 After the flushing with the gas, the connecting portion 111 and the gas supply pipe 134 are separated from each other, so that the discharge flame retardant cloth 110 can be dropped in a flat state.

The solenoid valve 136 is formed at one side of the gas supply pipe 134 as a component for opening and closing the supply of gas in accordance with a control command of the controller 140 in a state of being connected to the controller 140. At this time, the solenoid valve 136 collectively refers to a valve that opens and closes the pipeline (gas supply piping 134) using the electromagnetic force of the electromagnetic coil, which is also manufactured in various forms and corresponds to a commercially available technology. A detailed description thereof will be omitted.

5 and 6, the gas supplier 130 according to the second embodiment of the present invention includes an igniter 133, a nitrogen generator 135, and the like as shown in FIG. And a housing protruding pipe 137a protruding from one surface of the housing 137 is provided for coupling the connecting portion 111 to the housing 137. The housing protruding pipe 137a is formed in the housing 137,

The igniter 133 is a component that generates a high temperature by being ignited according to an electrical signal of the controller 140 in a state of being connected to the controller 140. The igniter 133 is installed at the center of the inside of the housing 137, ), And the gunpowder burned by the current can be used as a main material.

The nitrogen generator 135 generates a large amount of nitrogen gas instantaneously by utilizing a chemical reaction between sodium niobate (NaN 3 ) and iron oxide (Fe 2 O 3 ) Which is provided inside the housing 137 and surrounds the igniter 133 at the center.

At this time, the nitrogen generator 135 is formed by mixing a capsule containing sodium azide (NaN 3 ) and iron oxide (Fe 2 O 3 ), and the capsule itself is made of sodium azide (NaN 3 ) (Fe 2 O 3 ), but is characterized by being destroyed by high temperature.

The nitrogen gas production process will be briefly described as follows. The instantaneous high temperature and spark generated while igniting the igniter 133 according to the fire detection destroys the sodium nodide (NaN3) capsule and the discharged azide Sodium (NaN 3 ) reacts with iron oxide (Fe 2 O 3 ) and decomposes into sodium oxide and nitrogen (N 2 ). In this process, nitrogen gas generated in a large amount flows into the expansion tube 112 through the housing protrusion pipe 137a.

The control unit 140 controls the gas supply unit 130 and the like so that the discharge type flame retardant cloth 110 falls down in a deployed state and the lower fire is evolved when a fire is detected in the indoor space 10 by the fire detection sensor 120 And is basically connected to the fire detection sensor 120 and the gas supply unit 130, respectively, and receives signals generated from the fire detection sensor 120 and the gas supply unit 130, and transmits control commands for controlling them.

The control unit 140 may be installed in any position that can be stably operated without being affected by a fire. However, it is preferable that the control unit 140 is installed on a ceiling of the indoor space 10 or the like. The microcontroller unit, ), Arduino, and the like.

The objective implementation of the fire fighting system 100 through the control unit 140 described above is achieved by being coded in a programming language such as a machine language or the like and can be easily performed in various manners and forms A detailed description thereof will be omitted.

However, in the case of the gas supply unit 130 according to the first embodiment of the present invention, a brief description will be made with reference to FIG. 4 as to how the control unit 140 performs the fire fighting activity by an operation method or an algorithm.

First, as shown in FIG. 4 (a), when a fire occurs in the indoor space 10, the two fire detection sensors 120 sense whether or not high temperature heat is generated for a predetermined time interval within each sensing range, An electric signal is generated and the corresponding electric signal is transmitted to the controller 140. [

4 (b), the control unit 140 electrically opens the solenoid valve 136 of the gas supply unit 130 when all of the two fire detection sensors 120 transmit an electrical signal corresponding to the detection of the high temperature. . Accordingly, the expansion type flame retardant cloth 110 folded as the gas (particularly, carbon dioxide, nitrogen, halogen compound gas, etc. as fire extinguishing gas) is strongly introduced into the expansion tube 112 is spread in the horizontal direction.

At this time, since the rim portion 114 of the deploying flame retardant cloth 110 completely surrounds the edge region of the indoor space 10, more reliable sucking and extinguishing can be achieved. In addition to the unfolding operation of the discharge flame retardant fabric 110 and the injection nozzle 118 formed below the expansion tube 112, the gas (particularly, the carbon dioxide, nitrogen and / Halogen compound gas, etc.) are directed downward and gradually exhausted, resulting in gas-phase digestion.

Next, when the gas pressure is gradually increased as the gas is continuously supplied to the expansion tube 112 and the coupling force between the gas supply pipe 134 and the connection portion 111 is exceeded, the discharge type flame retardant cloth 110 is discharged from the gas supply pipe (134).

As shown in Fig. 4 (c), the discharge type flame retardant cloth 110 falls down in a state of being expanded by its own weight, so that the lower fire is slowly sucked and sucked, and at the same time, the gas system extinguishing by the jetting nozzle 118 is superimposed .

At this time, the air flow cut-off portion 116 is opened by the dropping of the discharge type flame retardant cloth 110, and the lower air flows upward to smooth the fall of the discharge type flame retardant cloth 110. In this process, the fire in the indoor space 10 can be quickly and completely evolved.

Finally, as shown in FIG. 4 (d), when the development-type flame retardant fabric 110 spreading in the horizontal direction reaches the bottom surface of the indoor space 10 and a series of evolution processes are completed, The flame-retardant cloth 110 is light in weight, so that the flame-retardant cloth 110 can be also used as a fire-retardant foam if necessary. Also, since the discharge type flame retardant cloth 110 used for the fire evolution can be reused, the fire system 100 can be operated at a low cost, and maintenance convenience can be achieved.

In the case of the gas supply unit 130 according to the second embodiment of the present invention, with reference to FIG. 5, with reference to FIG. 5, a description will be given of the first implementation A brief description will be given mainly on the differences between the examples.

First, the case of FIG. 4 (a) is the same as that of the above-described first embodiment.

4 (b), when all of the two fire detection sensors 120 send an electrical signal corresponding to the detection of high temperature to the control unit 140, the control unit 140 controls the igniter 133 So that the nitrogen generating device 135 immediately produces nitrogen. As a result, the nitrogen gas is strongly introduced into the expansion tube 112, and the expanded flame retardant cloth 110 is folded in the horizontal direction. The other operations are the same as in the case of the above-described first embodiment.

4 (c), as the internal pressure gradually increases as the nitrogen gas is continuously supplied to the expansion tube 112, if the coupling force between the housing projection tube 137a and the connection portion 111 is exceeded, The flame retardant cloth 110 is separated from the housing protrusion pipe 137a.
