Description

  The present invention relates to an initial fire extinguishing apparatus that can perform initial fire extinguishing when a fire occurs.

  In recent years, it has been obliged to install a fire alarm in each household under the revised Fire Service Law. There are two types of fire alarms, one that senses smoke and the other that senses heat from a fire. When a fire breaks out, residents who have been alerted by a fire alarm will be extinguished by the local fire extinguisher and other fire prevention methods. This fire extinguisher is classified into a type in which a fire extinguisher and a compressed gas are sealed in a cylinder, and a type in which a container filled with a fire extinguisher is charged toward the fire. Both are intended for initial fire extinguishment in the event of a fire, but if the fire alarm is unattended or if only a care recipient or infant is at home, the initial fire extinguishing device Even it cannot be used. In fact, in the tens of thousands of fires per year, it has been reported that initial fire extinguishing is impossible.

  Super high-rise apartments and high-rise apartments have diversified, and the density in a certain area has increased dramatically. Such buildings are rarely fired, but are highly airtight, so once a fire breaks out, they are burned into chemical products overflowing into the room, causing damage from toxic gases.

  Shrines and Buddhist temples and large-scale stores can install large-scale sprinklers with a large budget, but they cannot install expensive disaster prevention devices in small temples, stores, or homes.

  In recent years, low-cost initial fire extinguishers that can be used for initial fire extinguishing are also frequently caused by fire accidents caused by children playing in a car in the car or by spontaneous ignition of things placed in the car. Needed. In addition, fires in large trucks and late-night buses were devastating and secondary disasters were enormous.

  As a conventional initial fire extinguishing apparatus, there has been one disclosed in patent literature. For example, Patent Document 1 is intended to safely and surely extinguish a local fire in the form of a floating roof tank in place of the halon facility, and at least the incombustible gas fixed and compressed on the floating portion is stored. One fire detection head, a powder storage container in which a non-combustible gas compressed with a powder extinguisher is stored, a pressure detection means for detecting a pressure drop associated with the release of the non-combustible gas from the fire detection head, and pressure detection Determining means for determining a fire when the pressure detected by the means is less than or equal to a predetermined value, and at least one powder emitting head that is fixed on the floating part and emits a powder extinguishing agent when determined to be a fire. A fire extinguishing apparatus is disclosed.

Patent Document 2 is a fire extinguisher for an automobile, where a fire detector detects the occurrence of a fire by detecting an abnormal rise in the temperature of an engine room, and an injection means by a control means opening an on-off valve. It is disclosed that a liquid refrigerant is jetted out to extinguish the fire.
JP 2000-140142 A Japanese Patent Laid-Open No. 9-135917

  However, in Patent Document 1, the fire extinguishing device is installed in a large outdoor tank that stores a combustible liquid such as crude oil, and the powder fire extinguisher stored in the powder storage container senses a fire. It is configured to be injected into the tank. With this configuration, the fire extinguishing apparatus of Patent Document 1 is limited to a tank in which crude oil or the like is stored. Therefore, it is not applied to general household use. That is, in general households, even if a container for storing a powder fire extinguisher is disposed, it is necessary to find a fire source, and the fire extinguisher must be sprayed toward the fire source. The technical concept of fire extinguishing equipment cannot be adopted as it is. In the fire extinguishing apparatus of Patent Document 1, when a fire occurs, nitrogen gas is released from the fire detection head, and the pressure in the fire detection head decreases. When the pressure of the fire detection head decreases, a fire determination signal is output by the pressure switch, and the air operation valve is opened by the fire determination signal, and the powder fire extinguisher is injected from the powder holding container into the tank. Therefore, it takes time until the fire is detected and the powder extinguisher is sprayed, which may hinder initial fire extinguishing.

  The fire extinguisher of Patent Document 2 is a fire extinguisher for an automobile, and is provided in a refrigeration cycle apparatus that is arranged in an engine room and driven by an engine, and a branch pipe that is branched from a refrigerant condensing part of the refrigeration cycle apparatus. An on-off valve that adjusts the amount of the refrigerant and an injection unit that injects the refrigerant are provided. When a fire is detected, the control means opens the on-off valve, and the liquid refrigerant is injected from the injection means to extinguish the fire. However, since the refrigeration cycle apparatus disposed in the engine room is used, there is a possibility that the refrigeration cycle apparatus does not act smoothly due to a rapid temperature rise or the condensed refrigerant explodes. Moreover, as a vehicle using the refrigerant | coolant condenser which condensates and compresses the compressed refrigerant | coolant, when using the fire extinguisher of patent document 2, it was limited to the cold storage vehicle etc. as a large sized vehicle.

  The injection nozzle 36 and the rotation drive mechanism 38 are covered with a conical resin cover 37 slidably disposed on the upper and lower surfaces of the flange portion 311 formed at the lower end of the case body 31. The resin cover 37 is formed so as to be narrowed downward, and a plurality of long-suction intake holes 371 are formed on the inclined side surface over the entire circumference. The nozzle port 362 of the injection nozzle 36 is disposed so as to protrude from the resin cover 37 through one intake hole 371 within an open angle range in the base 45.

  The rotation drive mechanism 38 includes a drive motor 381 supported by the flange portion 311 of the case body 31 via a bracket, a drive gear 382 attached to the drive shaft of the drive motor 381, and a base portion 361 of the injection nozzle 36. And a driven gear 383 that is rotatably mounted together with the base portion 361. The injection nozzle 36 is rotated by the rotation of the driven gear 383, and the resin cover 37 is also slid in the rotation direction with respect to the flange portion 311 of the case body 31 by the rotation of the injection nozzle 36.

  A flame specifying sensor 39 and a temperature detection sensor 40 supported by a resin cover 37 are arranged below the injection nozzle 36. The flame identification sensor 39 is a sensor that identifies a fire source at the time of a fire, and the temperature detection sensor 40 is a sensor that instructs to open the electromagnetic valve 34 at a temperature of at least 80 ° C. Further, a cover body 41 screwed to the base 45 is attached in the vicinity of the electromagnetic valve 34, and a pressure gauge 42 that displays the pressure in the tank 33 is attached to the cover body 41. In addition, an electrical base 43 is attached to any of the inner wall surfaces of the base 45, and is connected to the electromagnetic valve 34, the flame specifying sensor 39, the temperature detection sensor 40, and the like by electrical wiring.

The position of the injection nozzle 36 is arranged at a position that falls within a 90 ° range in which the base 45 is opened. In the same manner as the fire extinguishing apparatus 10 of the above-described embodiment, a fire occurs, and the flame identification sensor 39 senses and identifies a place where the flame is high as a fire source. In other words, the drive motor 381 is operated by the flame specifying sensor 39 to rotate the injection nozzle 36 so that the nozzle port 362 of the injection nozzle 36 is directed to the fire source. At this time, the resin cover 37, the flame identification sensor 39, and the temperature detection sensor 40 also rotate simultaneously. When the temperature reaches 80 ° C., the solenoid valve 34 is opened by the temperature detection sensor 40, and the extinguishing agent 32 is injected by the pressure of the air 331. When the fire extinguisher 32 reaches the fire source, the scattered liquid is vaporized by the heat of the flame, and carbon dioxide is generated to cover the combustion material and block the combustion material and oxygen. Thereby, the initial fire extinguishing at the time of fire occurrence can be performed.

  The installation position of the fire extinguishing device 30 is not limited as long as it is a corner of the room, and may be anywhere from the floor to the ceiling.

  Next, the fire extinguishing apparatus of 3rd Embodiment is demonstrated based on FIGS.

  The fire extinguishing device 50 is mounted on a portable case body 51 that can be carried, and an injection nozzle 58 and a flame specifying sensor 59, which will be described later, are disposed so as to be rotatable by 180 °.

The hand-held portion 514 is not limited to the above form, and a known hand-held portion can be employed.

  As shown in FIG. 5, a tank 52 that stores compressed air 521 together with a fire extinguishing agent 53 is inserted into the case body 51. The tank 52 is supported on the inner wall surface of the case body 51 via a support member 54. The tank 52 is arranged with the inlet 52 a having a smaller diameter than the body portion of the tank 52 facing downward. The supply port 52 a is connected to the air piping member 55. A pressurizing valve 56 is disposed at one end of the air piping member 55 to apply an air pressure of 2.5 to 3.0 atmospheres in the tank 52. The other end of the air piping member 55 is connected to an electromagnetic valve 57, and the electromagnetic valve 57 is further connected to an injection nozzle 58 disposed in the rotary drum 60 via an air hose 551. Therefore, the extinguishing agent 53 accommodated in the tank 52 is injected with pressure by the compressed air 521, and thus is injected outward from the injection nozzle 58 when the electromagnetic valve 57 is opened.

  An injection nozzle 58 and a flame specifying sensor 59 are arranged in the rotating drum 60 housed in the drum housing groove 512 of the case body 51. In either case, the tip portion is disposed so as to protrude from the front surface of the rotary drum 60 to the outside. The injection nozzle 58 is mounted via a support bracket 601 so that the nozzle opening 581 is attached to be inclined downward, and the flame specifying sensor 59 is supported by the front inner wall surface. In addition, a through hole 602 through which the air hose 551 passes is formed on the lower surface of the rotary drum 60, and a rotary drive mechanism 61 that rotates the rotary drum 60 is connected to the upper surface.

  The rotation drive mechanism 61 is engaged with the drive motor 611 supported in the case body 51, the drive gear 612 mounted on the drive shaft of the drive motor 611, and the drive gear 612, and connected to the rotary drum 60 via the connection pin 614. And a driven gear 613 connected together.

  On the operation panel 513 on the front surface of the case body 51, a temperature detection sensor 62 is arranged at the upper center, and an on / off switch 63 (ON button 631, OFF button 632) for operating the fire extinguishing device 50 and a fire extinguishing at the center. A display lamp 64 for displaying whether or not the device 50 is operating and an alarm buzzer 65 (see FIG. 4) for notifying that a fire has occurred are arranged.

A second electrical base 67 is accommodated.

  The fire extinguishing agent 53 is housed together with air 521 formed of the same material as that of the first embodiment and compressed in the tank 52. The tank 52 may be formed of lightweight aluminum or a plastic bottle for carbonated beverages.

  Next, the operation of the fire extinguishing apparatus 50 configured as described above will be described.

  The fire extinguishing device 50 is carried in an indoor place where a fire is likely to occur, for example, in the kitchen 7. The fire extinguishing device 50 is installed at a position about 1 m higher than the floor surface if possible because the nozzle port 581 of the injection nozzle 58 is inclined downward. Since the fire extinguishing device 50 is configured to be portable, if the resident is at home and a fire breaks out, the fire extinguishing device 50 can be immediately moved to the place of occurrence. When the resident goes out, the ON button 631 of the on / off switch 63 is operated.

  When a fire occurs, the flame identification sensor 59 is activated and the rotation drive mechanism 61 is activated to identify a high flame location as a fire source. The nozzle port 581 of the injection nozzle 58 is directed to the fire source by the flame specifying sensor 59. When the temperature of the fire source reaches 80 ° C., the temperature detection sensor 62 detects and opens the electromagnetic valve 57, and the extinguishing agent 53 is discharged from the injection nozzle 58 by the pressure of the air 521 compressed in the tank 52. It will be sprayed toward the fire source. Therefore, as in the first embodiment, in the fire extinguisher 53, the scattered liquid is vaporized by the heat of the flame, generates carbon dioxide, covers the combustion material, and blocks the combustion material and oxygen. Thereby, the initial fire extinguishing at the time of fire occurrence can be performed.

  As described above, in the fire extinguishing apparatus of the present invention, as shown in the first to third embodiments, the fire extinguishing agents 16 and 32 are arranged in the house and look for the fire source where the fire has occurred, toward the fire source. , 53 can be injected, so that even if the resident is absent or only the care recipient or the infant is at home, the initial fire extinguishing can be surely performed. Moreover, since the fire extinguishing apparatus 10, 30, 50 itself can be easily installed in any of the houses and can be provided inexpensively with a simple configuration, it can be used safely in a general household.

  Next, a fourth embodiment in which a fire extinguishing device is mounted on a vehicle will be described with reference to FIG. The fire extinguishing apparatus 70 mounted on the vehicle includes a tank 71 containing compressed air 711 and containing a fire extinguishing agent 72, as well as a home fire extinguishing apparatus (the first to third embodiments described above), and a front end of the tank 71. A piping solenoid valve 73, an injection nozzle 74 attached to the tip of the solenoid valve 73, and a smoke detection sensor (or flame detection sensor) 75 for detecting flame or smoke are provided. The fire extinguishing apparatus 70 of the fourth embodiment can be suitably used mainly for small and medium-sized vehicles such as passenger cars, one-boxes, and campers.

  In the case of the fire extinguisher 70, the tank 71 in which the extinguishing agent 72 and the compressed air 711 are mixed may be installed in any position as long as it is a dead space except for the engine room. It is mounted on the lower side of the passenger seat. The electromagnetic valve 73 is housed in a storage box 77 together with an electric base 76 connected to the electromagnetic valve 73 by electric wiring, and is mounted on the back side of the dashboard. Moreover, the injection nozzle 74 and the smoke detection sensor (or flame detection sensor) 75 are for engine and in-vehicle use, and are respectively mounted at two locations. The engine injection nozzle 74 is mounted from the upper front side on the back of the hood toward the inside of the vehicle, and the vehicle injection nozzle 74 is mounted on the instrument panel. The engine smoke detection sensor (or temperature detection sensor) 75 is mounted at a rear position behind the hood, and the vehicle smoke detection sensor (or flame detection sensor) 75 is mounted near the front of the ceiling.

  The tank 71 is formed of an aluminum cylinder or a 500 ml carbonated beverage plastic bottle, and a pressure valve 71 a capable of increasing the pressure of the tank 71 is attached to the tip, and the electromagnetic valve 73 is wired to the electric base 76. The electric board 76 is wired to a cigar lighter power supply 78.

  In the above-described fire extinguishing apparatus 70, when a fire occurs from the engine room due to a trouble from the engine room, the smoke detection sensor (or flame detection sensor) 75 detects and opens the electromagnetic valve 73. When the electromagnetic valve 73 is opened, the extinguishing agent 72 to which pressure is applied by the compressed air 711 is ejected from the tank 71 and is ejected downward from an ejection nozzle 74 disposed in the engine room. Further, when a fire occurs from the inside of the vehicle, the smoke detection sensor (or flame detection sensor) 75 for the inside of the vehicle detects it and opens the electromagnetic valve 73. Similarly to the above, the fire extinguisher 72 accommodated in the tank 71 is ejected from the tank 71 by the pressure of the air 711 and ejected downward from the ejection nozzle 74 disposed in the vehicle. In the fire extinguisher 72, the scattered liquid is vaporized by the heat of the flame, and carbon dioxide is generated to cover the combustion material and block the combustion material and oxygen. Thereby, the initial fire extinguishing at the time of fire occurrence can be performed.

  Next, the fire extinguishing apparatus of 5th Embodiment is demonstrated based on FIG. The fire extinguishing apparatus 80 according to the fifth embodiment is suitably used for large vehicles such as trucks and buses in vehicles. The fire extinguishing apparatus 80 mounted on the vehicle includes a tank 81 for storing a fire extinguishing agent 82, and a tank 81. Are provided with an electromagnetic valve 83 and an injection nozzle 84 that are branched from the tip of the pipe, and a smoke detection sensor 85 and a temperature detection sensor 86 that are mounted in the engine room. The injection nozzle 84 is directly connected to the supply port 81a of the tank 81, and the distal end portion of the injection nozzle 84 is open, so that no pressure is applied to the extinguishing agent 82.

  The smoke detection sensor 85 and the temperature detection sensor 86 are connected to an alarm buzzer 87 as an alarm device arranged in the driver's seat. Further, a manual operation button 88 as a manual operation device for manually opening the electromagnetic valve 83 by the driver or assistant notified by the alarm buzzer 87 is disposed in the driver's seat.

  In the case of the fire extinguisher 80, the fire extinguishing agent 82 and the tank 81 may be mounted at any position as long as it is a dead space excluding the engine room. One end side of the electromagnetic valve 83 is piped to the tank 81 via the pressure reducing valve 89, and the other end side is piped to the air tank 90 connected to the compressor. As the air tank 90, one that is usually mounted for a brake pressurized to 9 to 10 atm is used. Moreover, the injection nozzle 84, the smoke detection sensor 85, and the temperature detection sensor 86 are provided in two places each for engine rooms and in-vehicles, as in the fourth embodiment. The engine room injection nozzle 84 is mounted above the engine 9 in the engine room, and the vehicle interior injection nozzle 84 is mounted on the instrument panel. The engine room smoke detection sensor 85 and the temperature detection sensor 86 are mounted at any position in the engine room, and the vehicle smoke detection sensor 85 and the temperature detection sensor 86 are mounted near the ceiling. .

  As the tank 81, a polyethylene polytank is used, and the supply port 81a is arranged at the lower side so that the fire extinguishing agent 82 can be discharged from the upper side through the lower oil supply port. The capacity of the fire extinguishing agent 82 stored in the tank 81 is stored in about 1 to 5 L depending on the vehicle type.

  In the case of a medium-sized truck that is not equipped with the air tank 90, the tank 71, the electromagnetic valve 73, and the injection nozzle 74 in which the extinguishing agent 72 is stored in the fourth embodiment described in the passenger car are used. In this case, the above-described alarm buzzer 87, manual operation button 88, and the like are separately attached.

  Next, the operation of the fire extinguishing apparatus 80 will be described.

  When a flame or smoke is detected due to some trouble in the engine room or in the vehicle while the bus or truck is running, the smoke detection sensor 85 or the temperature detection sensor 86 is activated to sound an alarm buzzer 87 in the driver's seat. The driver immediately stops on the shoulder of the road to ensure safety, visually confirms that there is a fire, and then presses the manual operation button 88 to open the solenoid valve 83. The pressure of the air tank 90 is normally set to a high pressure of 9 to 10 atm, and the air 811 that has passed through the electromagnetic valve 83 is reduced to about 3 atm by the pressure reducing valve 89 and sent into the tank 81.

  The injection nozzle 84 is directly connected to the supply port 81 a of the tank 81, and no pressure is constantly applied to the tank 81. However, air 811 having a pressure of about 3 atm reduced by the pressure reducing valve 89 is sent into the tank 81. When the air 811 is sent into the tank 81, the air inlet 81 a is opened, so that the air 811 is discharged together with the fire extinguishing agent 82. The fire extinguisher 82 discharged from the tank 81 is released in a drizzle state. In the fire extinguisher 72, the scattered liquid is vaporized by the heat of the flame, and carbon dioxide is generated to cover the combustion material and block the combustion material and oxygen. Thereby, the initial fire extinguishing at the time of fire occurrence can be performed.

  As described above, the fire extinguishing apparatus according to the fourth to fifth embodiments of the present invention is applied to small / medium-sized vehicles or large vehicles such as large trucks and buses, and fires generated from the engine room or the inside of the vehicle. The initial fire can be reliably extinguished. Moreover, since the structure is simple and can be easily installed, the vehicle owner can use it safely.
