Description

[Technical field]

[0001] The present invention relates to a fire extinguishing apparatus and a fire extinguishing system that are placed in an upright position in a target area to extinguish and suppress a fire. [Background technology]

[0002] Traditionally, firefighting equipment has been required to be installed in buildings according to their use, floor area, number of floors, etc., and has the ability to respond appropriately in the event of a fire.

[0003] In addition, in buildings such as office buildings, partitions are sometimes placed in the target area in order to make effective use of the target area, allowing the area to be easily divided, for example, by department or to arrange conference rooms, reception rooms, etc., without having to change the interior structure such as walls or windows. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2012-152261 A [Patent Document 2] JP 2012-179330 A [Patent Document 3] Utility Model Registration No. 3155375 Summary of the Invention [Problem to be solved by the invention]

[0005] However, sprinkler systems are installed on floors of a building with a certain number of floors or above, or on floors exceeding a certain area, and fire extinguishers and indoor fire hydrant systems are installed on floors that are not eligible for sprinkler systems. However, with these systems, it is sometimes difficult to know where they are located in the event of a fire, and many people are unfamiliar with using them, making it difficult to carry out fire extinguishing operations quickly and reliably when a fire occurs.

[0006] In addition, sprinkler systems are activated when the temperature rise caused by hot air currents meets the activation conditions, and they do not activate until the scale of the fire has grown to a certain extent, which means that it is not always possible to start extinguishing a fire early.

[0007] In addition, when the target area where sprinkler heads are installed is divided into compartments such as conference rooms by partitions, the compartment may include the ceiling area where sprinkler heads are not installed. In this case, the partitions may block the fire-extinguishing water from the sprinkler heads that are activated in the event of a fire, resulting in compartments that cannot be protected.

[0008] An object of the present invention is to provide a fire extinguishing device and fire extinguishing facility that utilizes a partition or other separating means that can be installed without changing the structure of the installation location, and efficiently suppresses and extinguishes a fire with a small amount of discharge.

[0023] (Flexible extinguishing agent piping) Part or all of the extinguishing agent piping shall be flexible extinguishing agent piping. Effect of the Invention

[0024] (Basic Effects) The fire extinguishing apparatus of the present invention is placed in an upright position in the target area without changing the structure of the placement location, and a partition means that physically constructs the boundary surface, for example a partition, has an extinguishing agent distribution path with multiple outlets for discharging extinguishing agent located in various locations on at least one side of the partition means. In the event of a fire, the extinguishing agent is discharged from the multiple outlets located in various locations on the boundary surface of the partition means. This ensures a wider release range than the point release of conventional sprinkler heads, which use the placement location as the release point, and reduces the number of areas that may be damaged by water spraying, making it possible to suppress and extinguish a fire with a small amount of extinguishing agent released.

[0025] Furthermore, if the outlet is designed to release the extinguishing agent in a direction perpendicular to the boundary surface of the partition means, the extinguishing agent can be released sideways (from the target area, for example, the side of a room, into the room), allowing the extinguishing agent to reach positions that are hidden from above, such as under tables or desks placed in the room, etc., thereby ensuring the suppression and extinguishing of the fire.

[0026] In addition, when the partition means is placed in a target area such as a room, it divides the location into two areas on either side of the boundary surface, and has a limited size that corresponds to a person's height, ceiling height, etc., and if the amount of extinguishing agent discharged from each outlet is less than that of a sprinkler head, it is possible to spray the extinguishing agent to every corner of the target area with a relatively small amount of extinguishing agent and with relatively little pressure, making it possible to efficiently suppress and extinguish a fire within a specified range in a short period of time.

[0027] (Effect of Extinguishing Agent Flow Path Arrangement on Row of Discharge Ports) In addition, by supplying extinguishing agent from both ends of a discharge port array element in which multiple discharge ports are arranged along, for example, the horizontal direction of the boundary surface, the discharge pressure of the multiple discharge ports can be made approximately uniform, making it possible to align the discharge pattern (angular distribution) and discharge amount of the extinguishing agent.

[0028] (Effect of the configuration of the partition means and the layout of the extinguishing agent flow path) In addition, by constructing the partition means with a flat panel member and a frame member and providing an extinguishing agent flow path in at least the panel member, it is possible to surface-discharge the extinguishing agent from a plurality of discharge ports arranged at various locations on the panel surface (boundary surface) of the panel member. In addition, in cases where a part or all of the panel surface (boundary surface) of the panel member is a glass window and is therefore not suitable as a location for disposing a discharge port, it is possible to deal with this by providing an extinguishing agent flow path in the frame member and providing a discharge port.

[0029] (Effect of extinguishing agent discharge pipe) In addition, by arranging an extinguishing agent discharge pipe having multiple discharge outlets arranged in the axial direction of the outer periphery (on a single horizontal straight line) as part of the extinguishing agent flow path provided in at least one of the panel member or frame member, the extinguishing agent flow path having multiple discharge outlets can be incorporated with a simple structure into the panel member or frame member that constitutes the partition means.

[0030] (Effects of extinguishing agent supply port and its connection form) In addition, by providing extinguishing agent supply ports on both sides of the partition means, not only when a single fire extinguishing appliance is placed, but also when multiple fire extinguishing appliances are placed in a connected manner, extinguishing agent from the extinguishing agent supply source can be supplied to each fire extinguishing appliance in sequence, and the multiple fire extinguishing appliances can work together to release extinguishing agent over a surface area, thereby suppressing and extinguishing a fire.

[0031] (Effect of fire extinguishing equipment in a partitioned area with connected partition means) Furthermore, partition means, for example partitions, may be used to form partitioned sections within a room in an office building or the like, such as a reception room, a conference room, etc., depending on the purpose of the room. In such cases, by making at least one of the partition means forming the partitioned section a fire extinguishing device equipped with an extinguishing agent distribution path and multiple release ports, in the event of a fire breaking out in the partitioned section, extinguishing agent can be released from the partition means provided as a fire extinguishing device to suppress and extinguish the fire.

[0032] (Three-way switching means for extinguishing agent distribution Effects of forming a route) Also, fire extinguishing agents distributionA bypass flow path is provided to bypass the route, and three-way switching means are provided on each of the partition means corresponding to the extinguishing agent supply ports on both sides.When multiple partition means are connected and arranged, the release of extinguishing agent from all partition means and the release of extinguishing agent from a specific portion of the extinguishing agent construction means can be freely set by switching the three-way switching means.

[0033] In addition, in a room in a building where sprinkler heads are installed, if sprinkler heads are not installed in the ceiling part of a compartment separated by multiple partitioning means, for example, partitions, the water from the sprinkler heads installed in the ceiling part outside the partitioned compartment will be blocked by the partitioning means and will not reach the compartment.However, at least one of the partitioning means separating the compartments functions as a fire extinguishing device, making it possible to reliably suppress and extinguish a fire that breaks out within the partitioned compartment separated by the ceiling part where no sprinkler heads are installed.

[0034] (Effects of fire extinguishing equipment using water pipes 1) In addition, by connecting water pipes to the extinguishing agent piping and discharging tap water as an extinguishing agent from the outlet of the fire extinguishing device in the event of a fire, a dedicated pump facility is not required, making installation easier and reducing costs.

[0035] (Effects of fire extinguishing equipment 2 using fire extinguishers) In addition, by connecting a fire extinguishing agent supply device, for example, a fire extinguisher nozzle, to the fire extinguishing agent supply port via the fire extinguishing agent piping, and opening the fire extinguisher when a fire occurs to release a specified fire extinguishing agent, for example, a powder fire extinguishing agent or a reinforced liquid fire extinguishing agent, from the fire extinguisher's outlet into the target area, it is possible to effectively suppress and extinguish a fire.

[0036] In addition, even if a person is unfamiliar with handling a fire extinguisher, which is a fire extinguishing agent supplying device, by simply removing the safety pin of a fire extinguisher placed, for example, outside the room in which the fire extinguisher is placed, and squeezing the lever to open the fire, high-pressure fire extinguishing agent can be supplied to the fire extinguisher placed inside the room and released into the target area, making it possible to effectively suppress and extinguish a fire in a short amount of time.

[0037] (Effects of fire extinguishing equipment 3 that uses fire extinguishers and water piping in combination) In addition to the effects of the fire extinguishing equipment 1 using water piping and the fire extinguishing equipment 2 using a fire extinguisher described above, when a fire occurs, the extinguishing agent supply device, for example a fire extinguisher, is opened to release the extinguishing agent from the fire extinguisher into the target area, thereby carrying out initial extinguishing of the fire; the extinguisher's release of the extinguishing agent lasts for a short period of time, for example, several tens of seconds; however, if the fire is not sufficiently suppressed and extinguished, tap water is released from the release port into the target area by opening the piping opening / closing means, thereby continuing to suppress and extinguish the fire; and since there is no time constraint on the release of tap water, it is possible to reliably extinguish a fire that has been suppressed by the release of the extinguishing agent from the fire extinguisher.

[0038] (Effect of the configuration of the piping opening and closing means) In addition, in fire extinguishing equipment 1 or 3, Target Area By opening the remote on-off valve through remote control based on a control signal from the fire detection equipment when a fire occurs, it becomes possible to release extinguishing agent from the fire extinguishing device linked to the fire detection, and also to release extinguishing agent from the fire extinguishing device by manually opening the manual on-off valve. This allows the device to operate faster than a sprinkler head that operates in response to the hot air current of the fire, and to suppress and extinguish the fire.

[0039] (Effect of connecting means for fire extinguisher) In addition, since the fire extinguisher is detachably connected to the extinguishing agent piping by a connecting means, when one extinguisher has been used, it can be replaced with an unused extinguisher as necessary, thereby continuing to release extinguishant and enabling reliable suppression and extinguishing of a fire.

[0040] In addition, when a fire occurs outside the protected area in a location where no fire extinguishing equipment is installed, the fire extinguisher can be detached by using the connecting means for the extinguishing agent piping and carried to the location in question for use, so that the fire extinguisher normally installed can be used in combination with the fire extinguisher for the fire extinguishing equipment, making it easier to maintain the fire extinguisher and reducing operating costs.

[0041] (Effect of flexible extinguishing agent piping) Furthermore, by making part or all of the extinguishing agent piping flexible, for example, an extinguishing agent hose, it becomes possible to flexibly respond to the movement or rearrangement of partitions, which serve as partition means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0043] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a disaster prevention system according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the following embodiment.

[0044] [Basic Concept of the Embodiment] First, a basic concept of the embodiment will be described. The embodiment generally relates to a fire extinguishing device and a fire extinguishing system.

[0045] The term "fire extinguishing equipment" refers to equipment that scatters or releases extinguishing agents to suppress and extinguish a fire, and is a concept that includes, for example, fire extinguishers, fire hydrants, and the like that are placed in a target area and used in fire extinguishing activities when a fire breaks out. Here, "suppressing and extinguishing a fire" combines the concept of suppressing a fire with another concept of extinguishing a fire. For example, "suppressing a fire" is a concept of suppressing the spread of a fire, the burning speed of a flame, or the scale of a fire, and "extinguishing a fire" is a concept of putting out the fire. Of course, it also includes cases where one of the two is used. In addition, the term "target area" refers to an area where a fire extinguishing equipment is placed, and includes, for example, an external area outside a building and an internal area inside a building, and the internal area inside a building is a concept that includes the rooms, corridors, stairs, and the like of a building. In addition, "fire extinguishing activities" refers to the actions of a person who uses a fire extinguishing equipment to suppress and extinguish a fire, and is a concept that includes, for example, initial fire extinguishing performed by a fire prevention manager or the like and firefighting activities performed by a fire brigade.

[0046] A fire extinguisher according to an embodiment includes a partition means, a fire extinguishing agent flow path, and a discharge port.

[0047] A "partitioning means" is a means for physically constructing a boundary surface in a target area by at least standing upright and placing the means without changing the structure of the placement location, such as the structure of a wall or window, and for example, when placed in a room of a building, is a means for dividing the placement location in the room into two areas on either side of the boundary surface, and is a concept that includes partitions, dividers, screens, etc. Here, "boundary surface" refers to each surface located on either side of the partitioning means.

[0048] Moreover, the "extinguishing agent flow path" is a path for circulating the extinguishing agent in the partition means, and is provided, for example, in at least one of the panel member and the frame member constituting the partition means to circulate the extinguishing agent. Here, the "panel member" is a flat member that physically constructs a boundary surface when placed in the target area, and is a member that divides the placement location of the target area into two areas on either side of the panel surface (boundary surface). Moreover, the "frame member" is a member that surrounds and supports the outer periphery of the panel member.

[0049] In addition, the "discharge port" is provided at each location of the extinguishing agent flow path and discharges the supplied extinguishing agent to at least one side of the partition means. For example, in the event of a fire, the extinguishing agent is discharged from a plurality of discharge ports provided at each location of the boundary surface of the partition means in a planar manner. Here, "planar discharge" refers to discharging the extinguishing agent in a planar manner from a plurality of locations by disposing a plurality of discharge ports (discharge points) at each location of the boundary surface, that is, dispersing the extinguishing agent from a wide range of the boundary surface by discharging the extinguishing agent from the discharge ports disposed at each location of the boundary surface. In addition to planar discharge, there are also point discharge and line discharge, and "point discharge" refers to discharging the extinguishing agent from one point by having a discharge port (discharge point) at one location (placement location), and "line discharge" refers to discharging the extinguishing agent linearly from a plurality of discharge ports arranged in a straight line.

[0050] In addition, the fire extinguishing appliances may be used either alone or in combination. Here, "connection of fire extinguishing appliances" means connecting partition means constituting a plurality of fire extinguishing appliances to form a predetermined partition section within a target area, for example.

[0051] In addition, the term "fire extinguishing equipment" refers to equipment that suppresses and extinguishes a fire using fire extinguishing equipment, and is a concept that includes, for example, equipment that activates fire extinguishing equipment through manual fire-fighting activities, and equipment that detects a fire using fire detection equipment that has a sensor connected to a receiver and automatically activates fire extinguishing equipment.

[0052] A fire extinguishing system using a fire extinguishing appliance includes an extinguishing agent pipe and an extinguishing agent supply source. Here, the "extinguishing agent pipe" is a pipe that supplies an extinguishing agent to the fire extinguishing appliance, and is a concept that includes, for example, pipes and hoses that supply extinguishing water, liquid extinguishing agent, powder extinguishing agent, etc. to the fire extinguishing appliance. Also, the "extinguishing agent supply source" is a source that supplies an extinguishing agent to the extinguishing agent pipe, and is a concept that includes, for example, a water pipe that supplies tap water, a pressurized water supply device equipped with a pump that supplies extinguishing water, an elevated water tank, and an extinguishing agent supply device, such as a fire extinguisher.

[0053] In the following description, the "target area" is a "room in a building", the "partitioning means" is a "partition", and the "extinguishing agent supply source" is a "water pipe" and / or a "fire extinguisher".

[0055] [a. Fire extinguishing equipment] First, an embodiment of the fire extinguisher will be described in more detail. As shown in FIG. 1, the fire extinguisher 10 is an appliance that scatters or releases an extinguishing agent to suppress and extinguish a fire. As an example, the fire extinguisher 10 is arranged in an arbitrary place that requires a partition in a room of a building such as an office building, standing on the floor without changing the structure and structural surface of the wall surface, ceiling surface, etc. The configuration and structure of the fire extinguisher 10 are arbitrary, but for example, the fire extinguisher 10 includes a partitioning means, an extinguishing agent flow path, and a discharge port, and as an example, the fire extinguisher 10 includes a partition 12 as the partitioning means. In the following description, the horizontal direction of the partition 12 in the disaster prevention device 10 in the standing state in FIG. 1 is referred to as the left-right direction, the vertical direction is referred to as the up-down direction, and the depth direction is referred to as the thickness direction.

[0056] (partition) The partition 12 comprises a panel member 14, a frame member, and a base 15. The panel member 14 constitutes a flat boundary surface, and divides the placement location of the fire extinguishing appliance 10 into two areas on either side of the boundary surface. The frame member may have any configuration or structure, but may be, for example, made up of an upper frame 16a, middle frames 16b and 16c, and a lower frame 16d, and surrounds and supports the outer periphery of the panel member 14. The base 15 allows the partition 12 to stand on the floor without changing the structural surface of the wall or ceiling, and is attached, for example, to the lower end of the middle frames 16b and 16c.

[0057] The length and width of the panel member 14 can be any size, for example, 900 mm wide x 1200 mm long, 900 mm wide x 1600 mm long, 900 mm wide x 2100 mm long, 900 mm wide x 2500 mm long, etc. The panel member 14 is a blind type that does not allow the opposite side to be seen, but other types including those with a window such as frosted glass in part are also included and are optional.

[0058] 3, the partition 12 has an upper frame 16a, middle frames 16b and 16c, and a lower frame 16d that constitute a frame member fixed around the periphery of the panel member 14 by, for example, bolts 31. Also, as shown in FIG. 4(B), the panel member 14 is fixed in the thickness direction by adhesive or the like with spacers 33 interposed between the first panel 30 and the second panel 32 at the four corners, and an internal space is formed between the first panel 30 and the second panel 32.

[0059] (Fire extinguishing agent distribution route) An extinguishing agent flow path 18 shown by a dotted line is provided inside the panel member 14 of the partition 12. This extinguishing agent flow path 18 is a path for flowing an extinguishing agent in the panel member 14, and although its configuration and structure are arbitrary, for example, it is arranged so as to have a four-stage ladder shape in the vertical direction (height direction), and the first stage, which is the top stage, is a linear flow path, and the second to fourth stages are provided with discharge ports 22, for example, at seven locations each. At the lower side ends on both sides of the extinguishing agent flow path 18, extinguishing agent supply ports 24a, 24b are arranged on the outside of the left and right side end faces via middle frames 16b, 16c.

[0060] (Fire extinguishing agent discharge pipe) Extinguishant discharge pipes 20 are disposed in the second to fourth stages of the extinguishant flow path 18, where the discharge ports 22 are disposed. The extinguishant discharge pipes 20 constitute a part of the extinguishant flow path 18, and for example, the extinguishant discharge pipes 20 are provided with a plurality of discharge ports 22 arranged in a single straight line in the axial direction of the outer periphery.

[0061] Here, by arranging an extinguishing agent discharge pipe 20 at each stage of the ladder-shaped extinguishing agent flow path 18, the horizontally arranged discharge port row is made into one discharge port row element, and the discharge port row elements are arranged in three stages from the second stage to the fourth stage to form the entire discharge port row.

[0062] The extinguishing agent flow paths 18 are connected to both ends of the extinguishing agent discharge pipe 20 so that the extinguishing agent is supplied from both ends. This makes it possible to make the pressure of the extinguishing agent supplied to the multiple discharge ports 22 in the same row approximately uniform, and to make the discharge pattern (angle distribution) and discharge amount in the same row uniform.

[0063] As shown in FIG. 5, the extinguishing agent discharge pipe 20 has a pipe body 34, both ends of which are closed. Piping A connection port 38 is provided, and a plurality of nozzle members 36 are arranged in a straight line and screwed into the outer periphery of the pipe body 34 in the axial direction. The nozzle members 36 have communication holes that communicate with the inside of the pipe body 34, and the openings of the communication holes form a plurality of discharge ports 22.

[0064] Here, the hole diameter of the discharge port 22 provided in the extinguishing agent discharge pipe 20 is, for example, about 3 to 4 millimeters. A hole diameter of about 3 to 4 millimeters corresponds to the hole diameter of one of a plurality of discharge holes formed in a shower head that uses tap water. Therefore, a tap water discharge pattern equivalent to one of the holes of a shower head is obtained from the discharge port 22, and this discharge pattern is discharged from the discharge ports 22 at various locations on the panel surface (boundary surface) on one side of the partition 12, resulting in an overall surface discharge.

[0065] Furthermore, when the nozzle member 36 is provided with a straight through hole, the discharge port 22 has a relatively narrow-angle discharge pattern, and when the opening of the communicating hole is widened into a cone shape, a wide-angle discharge pattern is obtained, and an appropriate opening shape is used according to the required discharge pattern. Discharge ports 22 with different opening shapes may be mixed.

[0066] In this embodiment, the central axis of the nozzle member 36 (the dashed line in FIG. 5(C)) is perpendicular to the panel surface, but is not limited to this. For example, the directionality of the extinguishing agent discharge can be adjusted by adjusting the inclination angle of the central axis with respect to the panel surface.

[0067] 4(B) is formed with a through hole 35 corresponding to the discharge port 22 of the panel member 14 shown in FIG. 3, and the discharge port 22 is formed by fitting a nozzle member 36 provided on the extinguishant discharge pipe 20 into the through hole 35, so that the extinguishant discharge pipe 20 can be easily positioned and fixed inside the panel member 14. When the nozzle member 36 is fitted into the through hole 35 of the first panel 30, it is desirable that the tip opening surface of the through hole of the nozzle member 36 be flush with the panel surface so that the discharge port 22 does not protrude from the panel surface.

[0068] The extinguishing agent flow path 18 is connected to both ends of the extinguishing agent discharge pipe 20 disposed within the panel member 14. In this case, any connection structure may be used, but for example, a rubber hose or a vinyl hose, preferably a reinforced rubber hose or vinyl hose made of woven fibers, is used as the extinguishing agent flow path 18, and the extinguishing agent flow path 18 is connected to both ends of the extinguishing agent discharge pipe 20 by using a T-joint.

[0069] In addition, the extinguishing agent discharge pipe 20 and the extinguishing agent flow path 18 may be prepared as a separately assembled assembly, which may then be placed between the first panel 30 and the second panel 32 via a spacer 33 and incorporated as a single unit, as shown in FIG. 4(B).

[0070] [b. Fire extinguishing equipment with a vertically positioned extinguishing agent discharge pipe] Next, a more detailed description will be given of an embodiment of the fire extinguisher 10 in which the extinguishant discharge pipes 20 are arranged vertically inside the panel member 14. As shown in Fig. 6, the fire extinguisher 10 (10a) of this embodiment has a plurality of extinguishant discharge pipes 20 arranged horizontally in the up-down direction (vertical direction) inside the panel member 14 of the partition 12. In addition, the upper ends of the extinguishant discharge pipes 20 arranged horizontally are connected to the extinguishant flow paths 18 arranged along the left end side, the upper end side, and the right end side of the panel member 14 between the extinguishant supply ports 24a, 24b.

[0071] In this case, although the extinguishing agent supply passage 18 is not connected to both the upper and lower ends of the extinguishing agent discharge pipe 20, since there is almost no pressure loss due to the difference in head when the extinguishing agent is supplied from the upper end of the extinguishing agent discharge pipe 20, even if only the upper end of the extinguishing agent discharge pipe 20 is connected, it is possible to make the discharge pressure of the multiple discharge ports 22 arranged vertically approximately uniform, and to align the discharge pattern (angular distribution) and discharge amount.

[0072] [c. Overview of fire extinguishing equipment] Next, an outline of the fire extinguishing system of this embodiment using the fire extinguisher 10 will be described. This fire extinguishing system is a system for suppressing and extinguishing a fire using the fire extinguisher 10, and includes, as an example, the fire extinguisher 10, an extinguishing agent pipe 25, an extinguishing agent supply source 26, and an on-off valve 28, as shown in FIG.

[0073] For the fire extinguisher 10, extinguishing agent piping 25 drawn from an extinguishing agent supply source 26 via a piping on-off valve 28 functioning as a piping on-off means is connected to an extinguishing agent supply port 24a, and the extinguishing agent is supplied to the extinguishing agent distribution path 18 inside the partition 12, making it possible to discharge the extinguishing agent from water outlets 22 provided at various locations. The extinguishing agent supply port 24b on the opposite side is closed. The extinguishing agent supply source 26 may be a water pipe, a fire extinguisher, or the like.

[0074] [d. Fire extinguishing equipment using water pipes] An embodiment of a fire extinguishing system using a water pipe as an extinguishing agent supply source will be described in more detail. As shown in Fig. 7, this fire extinguishing system is characterized by using a water pipe 47 as an extinguishing agent supply source. The configuration and arrangement of this fire extinguishing system are arbitrary, but for example, it includes the above-mentioned fire extinguishing device 10, extinguishing agent pipe 25, remote opening and closing valve 45, manual opening and closing valve 46, and water pipe 47. The fire extinguishing device 10 is placed at a desired position in a room that is a target area 11, and a panel surface (boundary surface) on one side of the panel member 14 where the discharge port 22 is arranged faces the area to be extinguished.

[0075] In the target area 11, a fire detector 44 is disposed as a fire detection facility and is connected to a receiver 42. A remote on-off valve 45 is also connected to the receiver 42. One end of the extinguishing agent piping 25 is connected to one of the extinguishing agent supply ports 24a (see FIG. 1) of the fire extinguisher 10, and the other end of the extinguishing agent piping 25 is connected to a water piping 47 via a parallel connection of the remote on-off valve 45 and a manual on-off valve 46 which function as a piping opening and closing means.

[0076] It is preferable that the extinguishing agent piping 25 be a normal piping having rigidity from the water piping 25 to the lead-in portion of the target area 11, and that within the target area 11 be a flexible piping, such as a pressure-resistant hose made of rubber or vinyl, so as to be able to flexibly respond to the arrangement and rearrangement of the partitions 12.

[0077] If a fire indicated by source 40 breaks out in the target area 11, the receiver 42 receives a fire signal from the fire detector 44, outputs a fire alarm, outputs an open control signal to the remote opening valve 45 to open it, supplies tap water to the fire extinguishing apparatus 10, and releases tap water from the outlets 22 provided in various places on the panel surface (boundary surface) on one side of the partition 12 toward the side where the fire has started, including the fire source 40, thereby suppressing and extinguishing the fire.

[0078] A row of outlets, for example 3 vertical by 7 horizontal outlets 22, is provided on one panel surface of the panel member 14 provided on the partition 12, and tap water is discharged as a fire extinguishing agent from the row of outlets into the target area 11 to suppress and extinguish the fire. At this time, the tap water is sprayed from the side onto the target area 11. For example, the discharge distance from the outlets 22 arranged in three tiers is such that the higher the position of the outlets 22, the farther the outlets will reach, covering a part or all of the area on the discharge side as the discharge range.

[0079] Furthermore, if a table or other furniture is placed within the discharge range, the water discharged from the discharge port 22 of the partition 12 will reach underneath the table. If it is desired to discharge water onto the ceiling, part of the topmost discharge port 22 may be oriented upward to wet the ceiling and prevent the spread of fire.

[0080] The extinguishing agent (tap water in this case) is released from multiple outlets 22 located in various places on the panel surface of the partition 12 as a surface release, which, unlike conventional point release where a sprinkler head is placed on the ceiling surface and only releases at a single point, can cover a wider range (spraying area) with the same amount of release.In addition, because tap water is sprayed laterally onto the location of the fire, the extinguishing agent can reach locations that are hidden from above, such as under tables and desks, making it possible to suppress and extinguish a fire with a smaller amount of extinguishing agent.

[0081] [e. Fire extinguishing equipment with a connected fire extinguisher] An embodiment of a fire extinguishing system to which a fire extinguisher is connected as an extinguishing agent supply source will be described in more detail. As shown in Fig. 8, this embodiment is characterized in that an extinguishing agent supply device, for example, a fire extinguisher 48, is used as an extinguishing agent supply source for a fire extinguisher 10. The configuration and arrangement of this fire extinguishing system are arbitrary, but for example, the fire extinguishing system includes a fire extinguisher 10, an extinguishant pipe 25, a fire extinguisher 48, a fire extinguisher connection part 56, and a of The fire extinguisher 48 supplies a predetermined extinguishing agent, for example, a powder extinguishing agent or a reinforced liquid extinguishing agent, to the fire extinguisher 10 and discharges the extinguishing agent from discharge ports 22 arranged at various locations on the panel surface on one side of the partition 12. Note that the discharge ports 22 are shown simplified as triangles.

[0082] Furthermore, the extinguishant piping 25 is a flexible piping, for example, a pressure-resistant hose made of rubber or vinyl, which allows for flexible arrangement and rearrangement of the partition 12 and the fire extinguisher 48. The fire extinguisher 48 has a main container filled with extinguishant under pressure, and when the safety pin 52 is removed and the lever 54 is pressed down, the extinguishant is opened and released from the hose 50.

[0083] One end of the extinguishant piping 25 is connected to the extinguishant supply port 24a of the partition 12, and the other end of the extinguishant piping 25 is connected to a fire extinguisher nozzle 58 at the tip of a hose 50 of a fire extinguisher 48 via a fire extinguisher connector 56. The fire extinguisher connector 56, which is a connecting means, is composed of the fire extinguisher nozzle 58 and a fire extinguisher connection port 60, and uses a known connecting joint similar to that used to detachably connect a hose to a water faucet with a single touch operation, for example.

[0084] Here, in this embodiment, the fire extinguisher nozzle 58 is formed by removing the nozzle already attached to the hose end of the fire extinguisher 48 and attaching a separately prepared fire extinguisher nozzle 58 in advance, but this is not limited to this.

[0085] FIG. 9 shows an example of a fire extinguisher connection part 56, which is equipped with a fire extinguisher nozzle 58 and a fire extinguisher connection port 60 that can be attached and detached with a one-touch operation. A separately prepared fire extinguisher nozzle 58 is provided at the tip of the hose 50 of the fire extinguisher 48, and the fire extinguisher connection port 60 is provided at the other end of the extinguishant piping 25, so that the hose 50 of the fire extinguisher 48 can be attached and detached to the extinguishant piping 25 with a one-touch operation.

[0086] The fire extinguisher nozzle 58 has a nipple 62 with an O-ring attached at its tip, and is connected and fixed by inserting the nipple 62 into the opening of the fire extinguisher connection port 60. The fire extinguisher connection port 60 has a slider 64, and the connected fire extinguisher nozzle 58 can be removed by sliding the slider 64 in the direction of the illustrated arrow.

[0087] The fire extinguisher 10 using the partition 12 of this embodiment has the structure shown in FIGS. 1 to 4, but may also be the fire extinguisher 10 (10a) shown in FIG.

[0088] In addition, since the fire extinguisher 48 is placed at a predetermined location, such as outside the room, away from the location of the fire, even if the user is unfamiliar with handling the fire extinguisher 48, the user can calmly perform the opening operation by removing the safety pin 52 of the fire extinguisher 48 and squeezing the lever 54 without panicking.

[0089] Furthermore, the discharge of extinguishing agent from the fire extinguisher 48 is short, for example, about 10 seconds, but if the fire is not extinguished even after the fire extinguisher 48 has been used up, the fire extinguisher nozzle 58 can be removed from the fire extinguisher connection port 60 of the fire extinguisher connection part 56 and replaced with an unused fire extinguisher 48 (a separately prepared fire extinguisher nozzle 58 attached to the hose 50) that has been prepared separately in advance, thereby allowing the discharge of extinguishing agent to be continued and ensuring the suppression and extinguishing of the fire. release A plurality of fire extinguisher connection parts are provided at a plurality of points on the pipe 20, and a plurality of fire extinguishers 48 are connected to the pipe 20 to supply a fire extinguishing agent. release Pre-connection to the tube 20 may allow for continued release of extinguishing agent without replacing a depleted extinguisher.

[0090] In addition, when a fire occurs in another location (a location where the fire extinguishing apparatus 10 of this embodiment is not installed), the fire extinguisher 48 can be removed from the extinguishing agent piping 25 and carried to the location of the fire for use, eliminating the need to increase the number of fire extinguishers installed, thereby reducing maintenance costs.

[0091] [f. Fire extinguishing equipment combining fire extinguishers and water piping] An embodiment of a fire extinguishing system combining a fire extinguisher and water piping as an extinguishing agent supply source will be described in more detail. As shown in Fig. 10, this fire extinguishing system is characterized by combining a fire extinguisher 48 and water piping 47 as an extinguishing agent supply source for the fire extinguishing device 10 placed in the target area 11. The configuration and arrangement are arbitrary, but for example, the fire extinguishing device 10, the extinguishing agent piping 25, the fire extinguisher 48, the fire extinguisher connection part 56, and the remote opening and closing valve are combined. 45 , manual on-off valve 46 and water piping 47.

[0092] One end of the extinguishing agent pipe 25 is connected to the extinguishing agent supply port 24a of the partition 12, and the other end is connected to a remote on-off valve connected in parallel, which is a pipe opening / closing means for opening and closing the pipe flow path by remote control or manually. 45 and manual on-off valve 46 It is connected to the water pipe 47 via

[0093] In addition, one end of the extinguishing agent pipe 25 and a remote opening and closing valve 45 and manual on-off valve 46The fire extinguisher 48 is connected to the piping branching off from between the fire extinguishing agent piping 25 (point A in the figure) via a check valve 68 serving as backflow prevention means for preventing backflow of tap water from the fire extinguisher piping 25 to the fire extinguisher 48. In addition, a fire extinguisher connecting part 56 is provided as a connecting means for detachably connecting the fire extinguisher 48 to the fire extinguisher piping 25. The fire extinguisher connecting part 56 is composed of a fire extinguisher nozzle 58 and a fire extinguisher connection port 60, and has a connecting joint structure similar to that shown in FIG. 9, for example.

[0094] Furthermore, water pipe 47 is connected to the connection part (point A in the figure) of check valve 68 of extinguishing agent pipe 25 via gate valve 66, and remote opening / closing valve 45 and manual opening / closing valve 46 functioning as remote / manual control valves for opening and closing the flow path continuing from water pipe 47 to extinguishing agent pipe 25 are connected in parallel between gate valve 66 and check valve 68 connection part (point A in the figure). Check valve 68 prevents tap water from flowing into fire extinguisher connection part 56 when tap water is supplied from water pipe 47 to extinguishing agent pipe 25.

[0095] The extinguishing agent piping 25 is made of rigid normal piping up to the retraction portion of the target area 11 beyond the connection portion (point A in the figure) of the check valve 68 of the extinguishing agent piping 25, but within the target area 11 it may be made of a flexible pressure-resistant hose made of, for example, rubber or vinyl, so as to be able to flexibly respond to the positioning and rearrangement of the partitions 12.

[0096] In the target area 11, a fire detector 44 is disposed as a fire detection facility and is connected to a receiver 42. A fire alarm light 43 is disposed near the location of the fire extinguisher 48 and is connected to the receiver 42. In addition, a remote opening / closing valve 45 is connected to the receiver 42.

[0097] The receiver 42 can be set to an automatic extinguishing mode and a manual extinguishing mode. The automatic extinguishing mode is set, for example, during the nighttime, and extinguishing agent (tap water) is discharged in conjunction with fire detection by the fire detector 44 (fire alarm of the receiver). The manual extinguishing mode is set, for example, during the daytime, and extinguishing agent is discharged by operating the fire extinguisher 48 or the manual opening / closing valve 45. In addition to switching between the manual extinguishing mode and the automatic extinguishing mode between the daytime and nighttime in this way, the manual extinguishing mode and the automatic extinguishing mode may be switched depending on whether people are present or absent, or these may be combined.

[0098] If the receiver 42 is set to manual extinguishing mode, when a fire breaks out in the target area 11 in which the fire extinguisher 10 is placed, the receiver 42 receives a fire signal from the fire detector 44 and outputs a fire alarm, and also turns on or flashes a fire alarm light 43 placed outside the room that is the target area 11 in which the fire has broken out.

[0099] When the relevant personnel become aware of the occurrence of a fire, they go to the location where the fire has occurred, and upon confirming the fire, they remove the safety pin 52 of the fire extinguisher 48 and push down the lever 54 to open it, which causes the fire extinguisher 48 to supply fire extinguishing agent to the fire extinguishing device 10, and the powder fire extinguishing agent or the like is released from a plurality of discharge ports 22 provided in various places on the panel surface of the partition 12 to suppress and extinguish the fire.

[0100] If it is not possible to confirm that the fire has been extinguished even after the extinguishing agent from the fire extinguisher 48 has been discharged, the manual on-off valve 46 is opened to supply tap water to the fire extinguisher 10 and the tap water is discharged from the multiple discharge ports 22 provided in various places on the panel surface of the partition 12 to suppress and extinguish the fire. The discharge of tap water is performed after the fire has been suppressed by the discharge of the extinguisher 48, and there is no time restriction on the discharge of tap water, making it possible to reliably extinguish the fire.

[0101] On the other hand, if the automatic fire extinguishing mode is set in the receiver 42, the receiver 42 receives a fire signal from the fire detector 44 and sends a control signal to the remote opening / closing valve 45 to open it, supply tap water to the fire extinguishing device 10, and releases the tap water from multiple outlets 22 provided in various places on the panel surface of the partition 12, thereby suppressing and extinguishing the fire.

[0102] Even in the automatic extinguishing mode, if, for example, a person who has rushed to the scene after receiving a fire report finds that the fire is not weakening, the receiver 42 can remotely open and close the remote valve. 45 After a predetermined operation is performed to close the extinguisher, for example, by canceling the automatic extinguishing mode and switching to manual extinguishing mode, the safety pin 52 of the fire extinguisher 48 is removed and the lever 54 is pushed down to open the extinguisher, and the extinguishing agent is supplied from the extinguisher 48 to the fire extinguishing device 10 and released from the discharge ports 22 located in various places on the panel surface of the partition 12, making it possible to suppress and extinguish the fire.

[0103] After the extinguishing agent has been discharged from the fire extinguisher 48 in this manner, the manual on-off valve 46 can be opened again to switch back to discharging tap water.

[0104] [g. Connected fire extinguishing equipment] An embodiment in which a plurality of fire extinguishing appliances are connected will be described in more detail. As shown in Fig. 11, in this embodiment, for example, partitions 12 (12-1, 12-2) of two fire extinguishing appliances 10 are arranged in a target area 11 by connecting metal fittings (not shown).

[0105] The partitions 12 (12-1, 12-2) of the fire extinguisher 10 arranged in a linked manner have the structure shown in FIG. 1 to FIG. 5 or FIG.

[0106] For the partitions 12 (12-1, 12-2) of the fire extinguishing apparatus 10 arranged in a connected manner, an extinguishing agent piping 25 from an extinguishing agent supply source 26 is connected to the extinguishing agent supply port 24a of the partition 12-1 located at the front, and at the joint A between the two, the extinguishing agent supply port 24b of the partition 12-1 located at the front and the extinguishing agent connection port 24a of the partition 12-2 located behind (at the end) are connected using an extinguishing agent piping such as a hose, and further, the extinguishing agent supply port 24b of the partition 12-2 is closed.

[0107] When the partitions 12 (12-1, 12-2) of two fire extinguishing appliances 10 are connected and arranged in the target area 11 in this manner, in the event of a fire, each of the multiple partitions 12 (12-1, 12-2) will release extinguishing agent over a surface area from multiple release ports 22 arranged in various places on the panel surface, ensuring a wide release range overall and making it possible to suppress and extinguish the fire with a small amount of extinguishing agent released.

[0108] In addition, when three or more disaster prevention devices 10 are arranged in succession, one extinguishant supply port 24a of the partition device 12 located in the middle is connected to an extinguishant piping from another partition device located in front, and the other extinguishant supply port 24b is connected to an extinguishant piping to another partition device located in the back.

[0109] [h. A connected fire extinguishing device that switches the extinguishing agent flow path using a three-way switching valve] An embodiment of a fire extinguisher in which, when the partitions 12 of a plurality of fire extinguishers 10 are connected, the extinguishing agent flow paths of each are switched by a three-way switching valve will be described in more detail.

[0110] As shown in FIG. 12(A), when partitions 12 (12-1, 12-2) of, for example, two fire extinguishing appliances 10 are connected and arranged in a target area 11, three-way switching valves 90a, 90b are provided on the extinguishing agent supply ports 24a, 24b sides of the panel members 14 of each of the partitions 12 (12-1, 12-2).

[0111] The three-way switching valves 90a, 90b have three ports a, b, and c, and allow switching operation to communicate between ports ab, between ports bd, or between ports a and ac. In addition, with the provision of the three-way switching valves 90a, 90b, a bypass flow path 19 is newly provided that connects the extinguishing agent supply ports 24a, 24b in the lateral direction (left-right direction) via the three-way switching valves 90a, 90b.

[0112] When extinguishing agent is to be sprayed from both of the connected partitions 12-1, 12-2, the three-way switching valves 90a, 90b provided on the partition 12 (12-1, 12-2) are switched as shown in Figs. 12(B) to (D), respectively.

[0113] The three-way switching valve 90a on the side of the extinguishant supply port 24a to which the extinguishant piping 25 of the partition 12-1 is connected communicates between the ports a and b, as shown in Figure 12 (B), and causes the extinguishant that has flowed in from the extinguishant piping 25 via the extinguishant supply port 24a to flow out to the extinguishant distribution path 18-1 located above.

[0114] In addition, the three-way switching valve 90b on the extinguishing agent supply port 24b side of the partition 12-1 communicates between the ports bc, as shown in Figure 12 (C), and causes the extinguishing agent that flows in from the extinguishing agent supply passage 18-1 located above to flow out to the next partition 12-2 side via the extinguishing agent supply port 24b.

[0115] In addition, the three-way switching valve 90a on the side of the extinguishant supply port 24a of the second partition 12-2 to which the extinguishant supply port 24a of the partition 12-1 is connected communicates between the ports ab, as shown in Figure 12 (D), and causes the extinguishant that has flowed in from the partition 12-1 via the extinguishant supply port 24a to flow out to the extinguishant distribution path 18-2 located above.

[0116] Furthermore, as shown in FIG. 12(E), the three-way switching valve 90b on the extinguishing agent supply port 24b side of the partition 12-2 closes port b by connecting ports a and b, thereby closing the flow path to the extinguishing agent supply port 24b of the extinguishing agent supply flow path 18-2 located above.

[0117] When spraying extinguishing agent only from the first partition 12-1, the three-way selector valve 90a on the extinguishing agent supply port 24a side is switched to a position that connects ports a and b as shown in Fig. 12(B), and the three-way selector valve 90b on the extinguishing agent supply port 24b side is switched to a position that connects ports a and c and closes port c as shown in Fig. 12(E). As a result, extinguishing agent is supplied and sprayed only to the extinguishing agent distribution path 18-1 of the partition 12-1, and extinguishing agent is not supplied to the second partition 12-2.

[0118] When extinguishing agent is sprayed only from the second partition 12-2, the three-way switching valves 90a, 90b on the extinguishing agent supply ports 24a, 24b of the first partition 12-1 are switched to a position in which ports a and a are communicated and port b is closed, as in Figure 12(E), and the extinguishing agent supplied from the extinguishing agent piping 25 is bypassed (bypassed) by the bypass flow path 19 of the partition 12-1 and supplied to the next partition 12-2.

[0119] The three-way selector valve 90a on the extinguishant supply port 24a side of the partition 12-2 is switched to a position that communicates between the ports a and b, as shown in Fig. 12(D). Also, the three-way selector valve 90b on the extinguishant supply port 24b side is switched to a position that communicates between the ports a and c and closes the port b, as shown in Fig. 12(E). This allows the extinguishant to be supplied to the partition 12-2 via the partition 12-1, and the extinguishant to be sprayed only from the partition 12-2.

[0120] [i. Fire extinguishing equipment forming a partition] An embodiment of a fire extinguisher in a case where a partitioned section is formed in a target area by connecting a plurality of partitions will be described in more detail. As shown in Fig. 13, a partitioned section 80 is formed in a target area 11 to be used as a conference room, a reception room, or the like, by connecting and arranging a plurality of partitions 12 (12-1 to 12-11) in a rectangular shape, for example, and arranging a door panel 78 at a predetermined position. In this case, at least one of the partitions 12 (12-1 to 12-11) forming the partitioned section 80, for example the partition 12 (12-2), is the fire extinguisher 10 (10a) shown in Figs. 1 to 5 or 6.

[0121] Therefore, if a fire breaks out in a partitioned section 80 separated by partitions 12 (12-1 to 12-11), a fire extinguishing agent can be surface-discharged into the partitioned section 80 from the partition 12 (12-2) provided as a fire extinguisher 10 (10a), thereby suppressing and extinguishing the fire.

[0122] Furthermore, in the target area 11 in which the sprinkler heads are arranged, if no sprinkler heads are arranged on the ceiling surface of the partitioned section 80 separated by the partitions 12 (12-1 to 12-11), the water discharged from the sprinkler heads arranged outside the partitioned section 80 will be blocked by the partitions 12 (12-1 to 12-11) and will not reach the partitioned section 80. However, one of these partitions, the partition 12 (12-2), functions as a fire extinguisher 10, thereby making it possible to reliably suppress and extinguish a fire that breaks out in the partitioned section 80 in which no sprinkler heads are arranged.

[0123] [j. Portable fire extinguishing equipment] An embodiment of the mobile fire extinguisher will be described in more detail. As shown in Fig. 14, the fire extinguisher 10 (10b) using the partition 12 of this embodiment is provided with casters 82, so that it can be moved and placed wherever necessary. Such a mobile disaster prevention device 10 (10b) is integrally provided with a fire extinguishant supply device, for example, a fire extinguisher 48, as a fire extinguishant supply source.

[0124] The fire extinguisher 48 is detachably mounted by a fixing band 84, for example, near a lower corner of the partition 12. The hose 50 of the fire extinguisher 48 is connected via a fire extinguisher connecting part 86 to an extinguishant supply port 24c provided on a nearby panel surface of the panel member 14, making it possible to supply extinguishant to the extinguishant distribution path 18. The fire extinguisher connecting part 86 has a connecting joint structure similar to that shown in Fig. 9, for example.

[0125] The fire extinguisher 10 (10b) of this embodiment can be easily moved using the casters 82, and since the fire extinguisher 48 is integrated into the partition 12, the partition 12 can be moved and placed at any position in the target area 11, and the fire extinguisher 10 (10b) can be used.

[0126] [k. Fire extinguishing device with outlet located in frame member] An embodiment of a fire extinguisher in which a discharge port is arranged on a frame member will be described in more detail. As shown in Fig. 15, the fire extinguisher 10 (10c) of this embodiment has a structure in which a frosted glass 88 is arranged on the upper side of a partition 12, and a panel member 14 is arranged below it, and since the panel member 14 is in a low position, a plurality of discharge ports 22 are arranged in a single horizontal straight line on one side of an upper frame 16a which is in a high position suitable for discharging a fire extinguishing agent.

[0127] More specifically, the extinguishing agent supply passage 18 shown by the dotted line is arranged inside the middle frame 16b, the upper frame 16a, and the middle frame 16c that cover the outside of the frosted glass 88 and the panel member 14, extinguishing agent supply ports 24a, 24b are provided on both sides of the lower part, an extinguishing agent discharge pipe 20 that constitutes part of the extinguishing agent flow path 18 is arranged inside the upper frame 16a that is located at a high position, and the extinguishing agent discharge pipe 20 has a plurality of discharge ports 22 arranged in a horizontal straight line as shown in Fig. 4. As a result, the partition 12 forms an entire discharge port row only with the discharge port row elements of the upper frame 16a in which the discharge ports 22 that are the discharge points are arranged in a horizontal straight line, and the fire is suppressed and extinguished by the linear discharge of the extinguishing agent.

[0128] In the fire extinguisher 10 (10c) of this embodiment, in addition to the outlet 22 disposed in the upper frame 16a of the partition 12, a plurality of outlets may be disposed at various locations on the panel surface of the panel member .

[0129] [l. Modifications of the present invention] Modifications of the fire extinguisher and fire extinguishing system according to the present invention will be described in more detail. The fire extinguisher and fire extinguishing system according to the present invention include the following modifications in addition to the above-described embodiment.

[0130] (Outlet arrangement) In the above embodiment, a plurality of outlets 22 are arranged at various locations on one side of the panel surface (boundary surface) of the partition 12, but this is not limited to this. For example, a plurality of outlets 22 may be arranged at various locations on both sides of the panel surface (boundary surface) of the partition 12.

[0131] (partition) The above embodiment takes as an example a fire extinguishing apparatus and a fire extinguishing system that uses a partition that stands on the floor surface using a pedestal, but the fire extinguishing apparatus and the fire extinguishing system may also use a fixed type partition that is fixedly disposed between the floor surface and the ceiling surface without changing the indoor structure.

[0132] In addition, the partition may have a structure in which multiple partitions are connected so that they can rotate freely. In this case, the fire extinguishing device structure may be provided in all of the partition devices, or in only some of the partitions.
