Description

Sticker type automatic fire extinguisher for fire suppression of small space

The present invention relates to an automatic fire extinguishing device for stickers for fire suppression in a small space, and more particularly, a distribution board configured to distribute and connect power or communication lines by forming the automatic fire extinguishing device in a plate shape and enabling attachment with adhesive tape It can be installed in a place where the internal space is narrow, such as a switchboard or a switchboard. In particular, since the ignition agent is integrally formed on one surface of the plate-shaped solid aerosol mixture, the separate container used by the existing fire detection unit can be removed, making it possible to reduce the overall thickness of the automatic fire extinguishing system, and to change the area provided to extinguish the necessary fire It relates to a sticker-type automatic fire extinguishing device that enables initial fire suppression by detecting a flame only by simply attaching it with adhesive tape in a narrow space, such as capable of providing capacity.

In general, electric fires occur frequently due to a short circuit of a switchboard or a switch box breaker of a switchboard. Since such narrow spaces such as distribution boards or distribution boards are covered from the outside, the occurrence of an internal fire is not recognized at the initial stage, and after a considerable amount of time has elapsed, the fire progresses to the outside and spreads to a large fire. .

In particular, most fire extinguishing facilities are installed on the ceiling and there is a considerable distance from the wall panel or switchboard, which is the ignition point of the fire.

Accordingly, in recent years, various researches on automatic fire extinguishing tools have been conducted so that the fire can be recognized at an early stage to prevent the spread of fire and suppress the fire.

Typically, it is a closed cylindrical automatic fire extinguisher, which is reduced in size and miniaturized, and a discharge port for discharging fire extinguishing agents is formed on the lower side of a circular disk plate or a cylindrical side surface, and the direction of the discharge port is changed. It is a structure that is installed facing the expected direction. However, the existing miniaturized cylindrical method has spatial limitations that make it difficult to install it in a location suitable for an ultra-small space such as an electric switchboard.

China Utility Model Registration No. 207980206U (Registered on October 19, 2018; hereinafter referred to as 'Prior Document 1') presented a smart fire extinguishing patch. The prior document 1 presented a structure that made it possible to release an aerosol through a wide surface by providing it in a disk shape, away from the conventional discharge method to the lower part or the side of the cylinder. However, in Prior Document 1, a coolant is provided inside, and a heat-sensing wire, which is a heat sensing means, is installed in communication with the inside and outside to transmit external heat to the inside. The use of phosphorus did not significantly reduce the reduction in the overall thickness.

Chinese Utility Model Registration No. 210472844U (registration on May 8, 2020; hereinafter referred to as 'Prior Document 2') presented a housing device for an aerosol fire extinguisher and an aerosol fire extinguisher. The preceding document 2 has a structure in which an aerosol is placed inside a disc-shaped housing and surrounded by a fireproof material, and the lead wire is communicated from the inside of the fireproof material to the outside through the through-via of the cover. This is a structure that cannot detect heat by itself, as it is ignited by receiving an ignition signal from the outside.

As described above, both of Prior Documents 1 and 2 provide a disk-shaped structure that escapes the aerosol emission structure to the floor or side of the existing cylindrical fire extinguisher and provides a structure that is discharged through the front surface, thereby minimizing the space of the place where it is installed. However, since it does not have a structure that detects heat and ignites itself, there is a disadvantage that a separate sensing device must be additionally connected by a lead wire.

Therefore, the need for a new type of automatic fire extinguishing system that can provide an automatic fire extinguishing function independently by significantly reducing the thickness of the fire extinguishing system can be easily installed even in a narrow place and equipped with a heat sensing means has emerged.

China Utility Model Registration No. 207980206U (2018.10.19.Registration): One species China Utility Model Registration No. 210472844U (2020.05.08. Registration):

As shown, the sticker-type automatic fire extinguishing device 10 for extinguishing a fire in an ultra-small space of the present invention is,

The plate-shaped fixing frame 20 with one side open, the solid aerosol mixture 30 stacked inside the fixing frame, the ignition agent 40 applied to the outer surface of the solid aerosol mixture, and moisture by closing the open side of the fixing frame It is configured to include a moisture barrier layer 50 that blocks the inflow.

The fixing frame 20 is formed in the form of a plate-shaped container as a whole by having an internal groove 21 formed on the inside from one side. The fixing frame 20 may be formed in a circle, a rectangle, or a polygon, and the thickness is formed to be 20 mm or less to be installed in a place where it is difficult to install an existing cylindrical fire extinguisher, and preferably to 10 mm or less to provide a space for installing a fire extinguisher. It can be installed even in a narrow place. In addition, the fixing frame is formed to be long left and right, so that it is thin but sufficient to supply a fire extinguishing agent through a wide surface.

In addition, fixing means are provided on the rear surface or the side surface to be easily coupled to the wall surface of the installation site or the inner surface of the facility. As the fixing means, it is possible to easily install inside the facility through an adhesive tape method for simply attaching to the facility using a double-sided adhesive tape 22, or a screw coupling bracket method for coupling the fixing frame with screws using a bracket.

In addition, the fixing frame 20 forms a fixing groove 23 or a fixing projection on the inner surface of the inner groove 21 as shown in FIGS. 3A and 3B, and the corresponding fitting projection 35 or the fitting groove is a solid aerosol It is possible to improve the bonding force of the solid aerosol mixture 30 and the fixing frame 20 so as to be formed on the back side of the mixture 30 . The fixing frame 20 itself can protect by blocking the transmission of the impact to the solid aerosol mixture inside when an external shock occurs, but when a microscopic shock is repeatedly transmitted by the external environment, the solid aerosol mixture 30 is repeatedly shaken due to this Fatigue failure may occur. Therefore, the solid aerosol mixture is not shaken or separated from the original position even when micro vibration is generated by the fastening of the fixing groove 23 or the fixing projection of the fixing frame 20 and the fitting projection 35 or the fitting groove of the solid aerosol mixture 30. It can be made to perform the role of a fixing pin that can be used. The fixing groove 23 or fixing projection and the corresponding fitting projection 35 or fitting groove may be formed in various shapes, but preferably a cross shape or a shape in which an annular shape is additionally formed at the end of the cross shape. This is to prevent sliding up, down, left and right.

The material of the fixing frame 20 is a thermosetting resin, especially nylon 6 or nylon 66, and silicone (a mixture of 15 to 25 wt% of Si powder) is added to prevent deformation even in high temperature heat. there is.

The solid aerosol mixture 30 is a plate-shaped fire extinguishing agent formed corresponding to the size of the inner groove 21 of the fixing frame.

The solid aerosol mixture 30 is composed of 50 to 70% by weight of potassium nitrate, 20 to 30% by weight of dicyandiamide (DCDA) and 10 to 20% by weight of resins.

As an oxidizing agent, potassium nitrate rapidly generates potassium radicals by thermal decomposition, and the potassium radicals react with OH radicals generated in the combustion reaction process of the fire target material to break the chain reaction, thereby performing fire extinguishing.

In addition, the dicyanamide is used as a coolant, and when mixed at 20% by weight or less, the cooling effect is reduced, and when mixed at 30% by weight or more, a large amount of harmful gas can be emitted during the combustion process, so it is mixed in the above range. It is preferable to use

In addition, resins are made to have excellent compressive strength while allowing the extinguishing agent to be processed in a certain form, and various resins for preparing a solid aerosol mixture can be used in general. When the resin is mixed at 10% by weight or less, it is difficult to maintain its shape due to its weak compressive strength. It is preferable to mix in a range

The solid aerosol mixture 30 composed as described above is formed into a thin plate having a thickness of 2 to 8 mm. When the thickness is less than 2 mm, the fire extinguishing performance per unit area is deteriorated, and it can be easily damaged during handling due to its thin thickness. In addition, since the overall thickness of the fire extinguishing device is increased when molded to more than 8 mm, it is not suitable for use in a narrow space, so it is preferable to use it within the above range. Of course, it can be molded to a thickness of 8mm or more and used to replace general fire extinguishing devices.

The solid aerosol provided by the reaction of the solid aerosol mixture 30 is harmless to the human body, does not inflict great damage to electronic equipment, and is convenient to use because it is easy to process the residue after digestion.

The solid aerosol mixture 30 according to the present invention may further include fibers to prevent cracking.

As a method of including fibers, there is a method of mixing natural fibers in a solid aerosol mixture. Various types of natural fibers to be mixed may be used, but representatively, hemp or cotton is used. The natural fibers are mixed in the raw material mixing step to prevent cracks and surface cracks caused by impact, and 5 to 20 parts by weight of natural fibers are added to the total 100 parts by weight of the solid aerosol mixture in which the fibers are not mixed. It can be mixed and molded into a plate. When the amount of the natural fiber is mixed in 5 parts by weight or less, the crack prevention effect is lowered, and when the natural fiber is mixed in 20 parts by weight or more, the degree of enhancement of the crack prevention effect is insufficient and the mixing amount of the natural fiber is increased, and the digestion performance is lowered It is preferable to mix in the above range as the result appears.

In addition, as another method of including the fiber, the solid aerosol mixture 30 is molded by interposing the glass fiber mesh 33 in the form of a net in the middle during molding. The glass fiber mesh 33 is preferably in the form of a mesh formed in a grid shape having a predetermined interval, and is interposed between the lower solid aerosol mixture 32 and the upper solid aerosol mixture 31 in the press forming process. Molding including the glass fiber mesh 33 prevents shape change due to pressure opening in the press molding process and prevents microcracks occurring on the surface during the curing process of the integrated solid aerosol mixture 30 after molding. , it can prevent cracks and damage caused by impacts applied to the surrounding area during handling.

Next, the ignition agent 40 is a component that is applied to the outer surface of the solid aerosol mixture 30 and is ignited by external heat.

The ignition agent 40 may be used alone or in a mixture of two or more of S, KClO ₃ , MnO ₂ , Si, CaCO ₃ , and may be set appropriately for a place of use by controlling the ignition temperature by adjusting the mixing ratio.

This ignition agent 40 may be provided by applying a point or line on the outer surface of the solid aerosol mixture or the entire surface. Here, it is possible to control the combustion rate of the solid aerosol mixture according to the application method. That is, when applied to the entire surface, the entire solid aerosol mixture is burnt at once when ignited by a hot air stream and the aerosol is emitted. It is possible to increase the aerosol emission time by increasing the combustion time.

The application of the ignition agent 40 is made by forming an ignition groove 34 on the outer surface of the solid aerosol mixture 30 as shown in FIG. 4 and stacking the ignition agent 40 to fill the ignition groove. can do. If the ignition groove is formed and the ignition agent is applied by filling the groove, the upper surface of the solid aerosol mixture to which the ignition agent is applied can be flattened, so that sealing by the moisture barrier layer can be made more easily thereafter, and the ignition agent and The contact area of the solid aerosol mixture can be increased to facilitate the transfer of ignition heat.

The moisture barrier layer 50 is a sealing layer for preventing moisture from flowing into the solid aerosol mixture built into the internal groove of the fixing frame.

The moisture barrier layer 50 is coupled to the fixing frame, as shown in FIGS. 1a to 1c, covering the open front name of the fixing frame and forming a plurality of aerosol outlets 511 inside the aluminum perforated plate 51 and; and a moisture-proof vinyl film 52 attached to the inner surface of the aluminum perforated plate to prevent external moisture from flowing into the interior through the aerosol outlet.

The aluminum perforated plate 51 is formed to have a thickness of 1 mm or less. The edge of the aluminum perforated plate is bent in a “L” shape to extend in the direction of the fixing frame 20, and after inserting the fixing frame into the extended inside, it can be molded in a “C” shape by folding the extended end side to contact the rear of the fixing frame. there is. Here, between the bent edge of the aluminum perforated plate and the fixing frame, a resin agent may be applied to ensure sealing.

The moisture-proof vinyl film 52 blocks the inflow of foreign substances from the outside, and is attached to cover the entire inner surface of the aluminum perforated plate 51 toward the solid aerosol mixture to protect the solid aerosol mixture from external foreign substances and moisture. It is preferable that the moisture-proof vinyl film is easily decomposed by the heat flow generated when a flame is generated so that the heat flow is transmitted to the inside.

In addition, the moisture barrier layer 50 may be a moisture-proof paint 53 applied to the outer surface of the solid aerosol mixture.

As shown in Figs. 2a to 2c, the upper surface of the solid aerosol mixture 30 to which the ignition agent 40 is applied or the moisture-proof paint 53 on the open upper surface of the fixed frame 20 in which the solid aerosol mixture to which the ignition agent is applied is embedded. ) to prevent the solid aerosol mixture from being exposed to the outside.

The moisture-proof paint 53 is prepared by mixing 10 to 30 parts by weight of a curing agent and 60 to 80 parts by weight of a diluent with respect to 100 parts by weight of an acrylic urethane paint, preferably 20 parts by weight of a curing agent with respect to 100 parts by weight of an acrylic urethane paint It is prepared by mixing 70 parts by weight of a diluent.

The prepared moisture-proof paint 53 can be applied to the upper surface of the solid aerosol mixture in a thickness of 15-20 μm to replace the moisture-proof vinyl film.

In the sticker-type automatic fire extinguishing device 10 for suppressing fire in an ultra-small space according to the present invention configured as described above, the applied ignition agent 40 is ignited by sensing the heat flow, and the ignition heat is a solid aerosol around the ignition agent. The mixture 30 is combusted, and a large amount of aerosol is generated in the combustion process and discharged to the front to achieve a fire-extinguishing action.

Therefore, it is possible to provide a useful device that can be used even in a narrow place where a cylindrical fire extinguishing device cannot be installed because it can be ignited by sensing the heat flow by itself without a separate sensing unit, and is provided in a thin plate shape.
