Description

Small Automatic Fire Extinguisher Including Lateral Outlet

The present invention relates to a small automatic fire extinguishing device having a side release port, and more particularly, a detection unit installed in a narrow space such as a distribution board or a switchboard where distribution and connection of power or communication lines are made to enable extinguishing of a fire at an early stage. The fire extinguishing unit is integrated with the ignition jade solid aerosol mixture to ignite, ignite, and burn only in the internal storage container, thereby lowering the risk of explosion and increasing the gas discharge pressure to facilitate the release of extinguishing gas. It relates to a small automatic fire extinguisher that does.

In general, fires caused by electricity account for a significant portion of all fire cases, and fires frequently occur due to short circuits in distribution boards such as electrical outlets or switch boxes or switchboards.

Since such narrow spaces such as distribution boards or distribution boards are covered from the outside, it is not immediately recognized when an internal fire occurs. .

In particular, since most fire extinguishing facilities are installed on the ceiling, there is a considerable distance from the wall panel or switchboard, which is the ignition point of the fire, so there is a problem that the fire cannot be detected early or the fire is not properly extinguished.

Therefore, various studies on automatic fire extinguishing tools are being conducted so that the fire can be recognized at an early stage to block the spread of the fire and suppress the fire.

Conventional automatic fire extinguishers usually have a closed cylindrical shape, and a discharge port for discharging fire extinguishing agents is formed on a circular disk plate, which is a lower surface, and is installed with the discharge port facing the fire expected direction. However, the conventional cylindrical method has a problem in that it is difficult to extinguish the fire because it is difficult to arrange the discharge port in the area where the fire is expected due to the spatial limitation to be installed in a narrow space such as an electric wiring board.

As shown, the small automatic fire extinguishing implement 1 according to the present invention includes an external storage container 10 . The external storage container 10 has a cylindrical shape with a closed bottom, and a plurality of discharge ports 11 are formed on the lower side of one side. The external storage container 10 may use a polygonal column other than a cylindrical column, and as a position where the discharge port 11 is formed among the sides, it is formed on the side in contact with the area where the coolant 30 is filled therein. The gas passes through the area filled with the coolant and is discharged to the outside through the outlet 11 .

On the inner surface where the outlet 11 is formed, a thin film or a dense mesh is further installed or attached between the coolant 30 to prevent the coolant from being discharged to the outside through the outlet and to prevent moisture or foreign substances from entering. can The thin film or mesh may be damaged by an increase in internal pressure to have a structure in which internal and external openings are made. In addition, the discharge port 11 may expand the diameter from the inside to the outside to facilitate the diffusion of the sprayed aerosol.

The internal storage container 20 is placed inside the external storage container. The internal storage container 20 is installed so as to be deflected away from the discharge port 11 in the lower inner portion of the external storage container (10). Of course, the internal storage container 20 and the external storage container 10 can be arranged concentrically, but since the gas discharge by combustion is intensively performed in one direction, the internal storage container is moved in one direction, for example, at the outlet where the gas is discharged. It is preferable to arrange the gas at a distance so that the gas is concentrated in one direction. In addition, the internal storage container 20 is formed with a plurality of through-holes on the side can be made to facilitate the discharge of the internal combustion gas. Here, since the present invention has a structure that allows gas to be released in one direction, the internal storage container 20 also forms a through hole only on the side in the direction in which the discharge port of the external storage container is formed rather than the entire side, so that the combustion gas in the internal storage container is discharged. Let it be discharged to the outside through the through hole of the internal storage container and the outlet of the external storage container.

Inside the internal storage container 20, the solid aerosol compound 22 is placed or filled only on the lower side so that a space portion 21 of a certain size is formed on the upper side to be stored. The solid aerosol compound can be molded to a certain size by adding a resin component. For example, it can be formed in a size similar to the inner diameter of the internal storage container to be placed in the internal storage container.

The composition of the solid aerosol compound 22 is 50 to 70% by weight of potassium nitrate, 20 to 30% by weight of dicyandiamide (DCDA), and 10 to 20% by weight of resins. When the solid aerosol compound is burned, a solid aerosol component containing a large amount of potassium is generated. A solid aerosol containing a large amount of potassium is harmless to the human body, does not cause great damage to electronic equipment, and is easy to dispose of residues after digestion.

The solid aerosol compound 22 stored in the internal storage container 20 is formed in the form of a cylindrical body having a vertical hole in the center, and the flame transmitted from the ignition jade assembly 60 to be described later is a cylindrical solid aerosol compound internal vertical hole. It is delivered to the widest surface through the air, so that the combustion occurs at the same time as possible, so that the rapid fire extinguishing action can be achieved by increasing the amount of gas generated. The upper space 21 of the internal storage container 20 is provided as a space into which the ignition and combustion part of the ignition jade assembly can be inserted.

Therefore, in the small automatic fire extinguishing implement 1 according to the present invention, since all combustion takes place in the internal storage container 20, the pressure in the internal storage container can be increased by using the gas generated in the ignition process, so that the internal storage container It is possible to reduce the solid aerosol component used to increase the gas pressure, and to reduce the overall size by the reduced amount to enable miniaturization.

In addition, as shown in Figure 2b, the internal storage container 20 is composed of a cylindrical grooved pipe 23 with a closed lower portion and an open side, and the open side portion of the cylindrical grooved tube is a perforated plate 24 having a plurality of through holes. ) has a closed structure. The perforated plate 24 may be configured such that the central portion protrudes in the direction of the discharge port of the external storage container and a part of the ignition jade assembly 60 disposed on the central axis is internally inserted. Of course, as shown in FIG. 2c , the inner angle at which both ends of the cylindrical groove tube 23 are formed may be formed to have an obtuse angle greater than 180°, so that the central portion in which the spark jade assembly 60 is placed is contained. Here, the lower part of the internal storage container is to be closed by the internal storage container itself, or the internal storage container is provided in the form of a tube with an open lower part and is in close contact with the bottom surface of the external storage container to be closed by the external storage container. can In the present invention, it may include both a tubular form or a container form as described above.

The internal storage container 20 having the above structure is supplied to the inner space of the adjacent external storage container through the through hole of the perforated plate 24 when the internal pressure rises, and through the outlet 11 of the external storage container 10 external exhaust is carried out.

A coolant 30 is filled in a space between the external storage container 10 and the internal storage container 20 in which the discharge port is formed. The coolant 30 is a material that cools the high-temperature gas discharged from the through hole of the internal storage container. Representatively, it may be a solid mixture of at least one material selected from the group consisting of MgCO ₃ , H ₃ BO ₂ , SiO ₂ and CaSO ₄ 2H _{2 O}

The coolant is formed in particles larger than the discharge port of the external storage container to prevent it from being discharged to the outside, and is configured in a circular shape so that the distance between the particles is increased so that the gas can be discharged into the space between the particles.

A separation pipe 40 is built in the external storage container 10 so that the lower space and the upper space in which the coolant 30 and the internal storage container 20 are disposed are spaced apart by a predetermined distance. The upper and lower washers 42 and 41 are respectively placed on the upper and lower portions of the separation tube 40 to partition the upper and lower layers. The upper washer 42 and the lower washer 41 may seal the edges in contact with the inner surface of the external storage container to further increase the sealing force. The separation tube dividing the upper and lower spaces by a predetermined distance prevents the heat of the lower part, particularly the internal storage container, from being transferred to the upper side, thereby enabling the upper structure to be recycled if necessary.

A sensing housing 50 is installed inside the upper space of the external storage container 10 .

The lower end of the sensing housing 50 is placed on the upper washer 42 of the separation tube 40 , and a coupling part 511 is formed on the side thereof to be combined with the upper end of the external storage container 10 .

The ignition jade assembly 60 is installed at the lower end of the sensing housing.

The ignition jade assembly 60 is electrically connected to the electromotive force generating means 53 and receives the electromotive force to be ignited to generate a flame. The ignition jade assembly 60 inserts a lower washer into the part that generates ignition and flame so that it is placed in the upper space of the internal storage container to cause ignition and flame generation in the internal storage container.

A glass bulb 70 is installed at the upper end of the sensing housing 50 in the axial direction. The glass bulb 70 is a glass tube body filled with a temperature-sensitive thermal expansion fluid therein, and when it reaches a specific temperature, the internal thermal expansion fluid expands to damage the glass tube body. The thermal expansion fluid in the glass bulb 70 (thermobulb; thermobulb) is alcohol, glycerin, toluene, xylene, trichloroethylene, and tetrachlorethylene. It may include at least one selected from the group including. The glass bulb may be destroyed at a temperature of 50 to 270 °C, and the breaking temperature may vary depending on the fluid composition ratio of the thermal expansion fluid.

A glass bulb fixing body 80 in the form of a cap containing the glass bulb 70 is installed at the upper end of the sensing housing 50 .

The glass bulb fixing body 80 is equipped with an adjustment screw 81 that moves up and down as it rotates in contact with the upper end of the glass bulb and presses the glass bulb, and a plurality of openings are formed on the side surface of the glass bulb. The direction should be as open as possible. That is, the upper plate member to which the adjusting screw is mounted may be provided in a form supported by a plurality of pillar members.

The inner diameter of the glass bulb fixture 80 is formed to a size that can accommodate the moving guide 534 moving up and down among the electromotive force generating means of the sensing housing to form a moving space 82 . That is, the glass bulb 70 is usually placed in the moving space 82 so that any member of the electromotive force generating means, for example, a moving guide 534 to be described later, does not rise, and when a fire occurs, the glass bulb 70 is heated. ) is broken so that the movement guide 534 rises to the movement space 82 .

3 and 4 are cross-sectional views and exploded cross-sectional views showing the sensing housing according to the present invention.

As referenced, the sensing housing 50 includes a base 51 inserted into an upper portion of the external storage container 10, a housing 52 coupled to the upper portion of the base, and sliding movement in the axial direction within the base and the housing.

That is, the lower side of the inner moving space 512 is formed similar to the diameter of the moving guide 534 that is vertically moved so that the moving guide can move vertically, and the upper side of the inner moving space formed with a step difference by expansion has a larger diameter than the lower side. It is formed to enable additional mounting of a member disposed in an annular shape.

The housing 52 is a tubular body coupled to the upper portion of the base, and has an inner diameter similar to the inner diameter of the vertically moved movement guide to enable vertical movement of the movement guide.

The housing 52 forms a stepped on the outer surface to have an upper outer surface diameter and a lower outer surface diameter different from each other, and the lower side is inserted into the base 51 and limits the inner penetration depth by the stepped. A space is formed in the vertical axial direction between the lower end of the housing 52 and the extended area of the base inner moving space 512 by limiting the inner depth, and a magnetic force tube 531 to be described later is placed in the space.

In addition, the housing 52 may form a screw thread on the outer circumferential surface of the portion that is inserted into the base, and form a screw thread corresponding to the inner circumferential surface of the upper upper portion of the base to perform screw coupling, or may be coupled by an interference fit method. In addition, various methods such as bonding by bonding may be applied.

The electromotive force generating means 53 is configured to include a magnetic force tube 531 , a spring 532 , a magnet 533 , and a movement guide 534 .

The magnetic force tube 531 is a tube that is inserted into the extended area of the base 51, and the inner diameter is such that the movement guide 534 passes and is preferably formed to have the same diameter as the lower area of the inner movement space 512 of the base. will be. When the inner diameter is formed in this way, the lower region of the base inner movement space 512 and the inner diameter of the magnetic force tube 531 and the housing 52 are all the same, so that the movement guide 534 slides in the vertical axial direction without being caught. can be done easily. A plurality of coils 535 are wound on the outer surface of the magnetic force tube 531 . For coil winding, the upper and lower ends of the magnetic force tube may be formed with flanges extending horizontally.

The spring 532 is disposed on the bottom surface of the inner moving space 512 of the base 51 . The spring 532 is installed in the axial direction using a coil spring, descends by receiving a load, and is deformed upward by elastic restoration when the load is removed. In order to arrange the spring 532 in place, a locking projection may be protruded in the axial direction from the bottom of the inner movement space of the base to guide the bottom of the spring to be disposed at the center of the axis or to fix the bottom of the spring.

The magnet 533 is a permanent magnet placed on the top of the spring 532 . The magnet generates an electromotive force by the action with the coil 535 while passing through the magnetic force tube 531 by vertical movement.

The moving guide 534 is a bar body that is integrally coupled to the lower end of the magnet 533 and moves up and down together with the magnet in the axial direction. The upper end of the moving guide 534 forms a fitting groove so that the lower end of the glass bulb 70 is fitted. The movement guide 534 is mounted so as to be slidably moved up and down along the vertical hole formed by the inner movement space of the base, the center of the magnetic force tube, and the center of the housing. That is, in the state in which the glass bulb is mounted, it descends so that the spring is placed in a compressed state, and when the glass bulb 70 is damaged by heat, it is moved upward by the elastic force of the spring 532, and in the process of moving, The magnet 533 passes through the coil 535 winding portion of the magnetic force tube 531 to generate an electromotive force by magnetic force.

Therefore, in the electromotive force generating means 53, the magnetic force tube 531 is fixedly installed between the base 51 and the housing 52, and receives the elastic force of the spring 532 due to the breakage of the glass bulb 70.

The ignition jade 63 is a gunpowder that is ignited with only a small amount of electromotive force. The ignition jade 63 is disposed in the powder bag 61, but is arranged to be inserted inside the solid aerosol powder 62 layer so that the solid aerosol powder is easily ignited upon ignition.

One end of the electric wire 64 is connected to the coil 535 of the magnetic force tube 531 of the electromotive force generating means, and thus receives the electromotive force generated when the magnet passes into the magnetic force tube and transmits it to the ignition jade on the other side. The electric wire is wired to communicate with the coil of the magnetic force tube through a through hole connected to the internal magnetic force tube on the side of the base, and wiring may be made to connect the coil 535 and the ignition jade 63 by various methods.
