Description

The present invention relates to a fire extinguishing device and fire extinguishing equipment that are placed in an upright position in a target area to extinguish and suppress a fire.

Traditionally, firefighting equipment has been required to be installed according to the building's purpose, floor area, number of floors, etc., and includes fire extinguishers, indoor fire hydrant equipment, and sprinkler equipment, allowing for appropriate response in the event of a fire.

In addition, in buildings such as office buildings, partitions are sometimes placed in the target area to effectively utilize the target area, allowing for simple division into departments, for example, or the arrangement of conference rooms and reception rooms, without having to change the interior structure of the walls, windows, etc.

However, sprinkler systems are installed on floors of buildings with a certain number of floors or more, or on floors exceeding a certain area. Floors that are not subject to sprinkler systems have fire extinguishers and indoor fire hydrant systems installed. However, with these systems, many people do not 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 breaks out.

In addition, sprinkler systems are activated when the temperature rise caused by hot air currents meets the activation conditions, and do not activate until the scale of the fire has reached a certain level, which creates the problem that it is not always possible to start extinguishing the fire early.

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

The present invention aims to provide a fire extinguishing device and fire extinguishing equipment that efficiently suppresses and extinguishes fires with a small amount of discharge by utilizing a partition or other separating means that can be installed without changing the structure of the installation location.

(Basic Effects)
The fire extinguishing equipment 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, thereby ensuring a wider release range than the point release of conventional sprinkler heads, which have the placement location as the release point, and reducing 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.

In addition, if the extinguishing agent is discharged from the discharge port in a direction perpendicular to the boundary surface of the partition means, the extinguishing agent can be discharged sideways (from the target area, for example, the side of a room, into the room), allowing the extinguishing agent to reach locations hidden from above, such as under tables or desks placed in the room, and thus ensuring the suppression and extinguishing of the fire.

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 a boundary surface, and has a limited size that corresponds to a person's height or ceiling height, etc. Also, 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 low pressure, making it possible to efficiently suppress and extinguish a fire within a specified range in a short period of time.

(Effect of arrangement of extinguishing agent flow path relative to 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.

(Effects 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.

(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 equipped with multiple discharge outlets can be incorporated with a simple structure into the panel member or frame member that constitutes the partition means.

(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, thereby suppressing and extinguishing a fire.

(Effect of fire extinguishing equipment in a partitioned compartment with partition means connected)
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, 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.

(Effect of forming a fire extinguishing agent flow path by three-way switching means)
In addition, a bypass flow path that bypasses the extinguishing agent flow path and a three-way switching means is provided corresponding to the extinguishing agent supply ports on both sides, and 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 specified portion of the extinguishing agent construction means can be freely set by switching the three-way switching means.

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

(Effects of Fire Extinguishing Equipment 1 using Water Pipes)
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.

(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.

In addition, even if a person is unfamiliar with the use of a fire extinguisher, which is a fire extinguishing agent supplying device, by simply pulling out 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 valve, 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 suppress and extinguish a fire effectively in a short period of time.

(Effects of fire extinguishing equipment 3 that uses both fire extinguishers and water piping)
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 extinguishant is continued 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 extinguishant from the fire extinguisher.

(Effects of the configuration of the pipe opening and closing means)
In addition, in the fire extinguishing system 1 or 3, the remote on-off valve can be opened by remote control based on a control signal from the fire detection system when a fire occurs in the target area , allowing the fire extinguishing device to release extinguishing agent in conjunction with fire detection, and the manual on-off valve can also be manually opened to release extinguishing agent from the fire extinguishing device. This allows the fire to be suppressed and extinguished faster than a sprinkler head that is activated by the hot air current of the fire.

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

In addition, if a fire occurs outside the protected area in a location where no fire extinguishing equipment is installed, the fire extinguisher can be removed by connecting the extinguishing agent piping and carried to the location in question for use, allowing the fire extinguisher normally installed to be used in combination with the fire extinguishing equipment, making it easier to maintain the fire extinguisher and reducing operating costs.

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

Below, an embodiment of the disaster prevention equipment 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.

[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.

"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, etc. 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 the 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 the concept of putting out the fire. Of course, it also includes cases where one or the other is used. Furthermore, "target area" refers to the area where a fire extinguishing equipment is placed, and includes, for example, the external area outside the building and the internal area inside the building, and the internal area inside the building is a concept that includes the rooms, corridors, stairs, etc. of the building. Furthermore, "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 carried out by a fire prevention manager or the like and firefighting activities carried out by a fire brigade.

The fire extinguishing device according to the embodiment includes a partition means, a fire extinguishing agent flow path, and a discharge port.

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. For example, when placed in a room of a building, the means 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, room dividers, screens, etc. Here, "boundary surface" refers to each surface located on either side of the partitioning means.

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 frame member that constitute the partition means to allow the extinguishing agent to flow. Here, the "panel member" is a flat member that physically creates 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). The "frame member" is a member that surrounds and supports the outer periphery of the panel member.

The "discharge port" is provided at each location in the extinguishing agent flow path, and discharges the supplied extinguishing agent onto at least one side of the partition means. For example, in the event of a fire, the extinguishing agent is discharged from multiple discharge ports provided at each location on the boundary surface of the partition means in a planar manner. Here, "planar discharge" refers to discharging the extinguishing agent from multiple locations in a planar manner by disposing multiple discharge ports (discharge points) at each location on the boundary surface, that is, distributing the extinguishing agent from discharge ports disposed at each location on the boundary surface over a wide area 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 (location), and "line discharge" refers to discharging the extinguishing agent in a line from multiple discharge ports arranged in a straight line.

Furthermore, fire extinguishing appliances may be used either individually or in combination. Here, "connecting fire extinguishing appliances" means connecting the partitioning means constituting multiple fire extinguishing appliances to form a specified partition section within a target area, for example.

In addition, the term "fire extinguishing equipment" refers to equipment that suppresses and extinguishes fires using fire extinguishing equipment, and is a concept that includes, for example, equipment that activates fire extinguishing equipment through manual firefighting activities, and equipment that detects a fire using fire detection equipment with a sensor connected to a receiver and automatically activates fire extinguishing equipment.

A fire extinguishing system using a fire extinguishing appliance includes an extinguishing agent piping and an extinguishing agent supply source. Here, "extinguishing agent piping" refers to piping that supplies extinguishing agent to the fire extinguishing appliance, and is a concept that includes, for example, piping and hoses that supply extinguishing water, liquid extinguishing agent, powder extinguishing agent, etc. to the fire extinguishing appliance. Also, "extinguishing agent supply source" refers to a source that supplies extinguishing agent to the extinguishing agent piping, and is a concept that includes, for example, water pipes that supply tap water, pressurized water supply devices equipped with pumps that supply extinguishing water, elevated water tanks, and extinguishing agent supply devices, such as fire extinguishers.

In the following explanation, 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."

[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 or ceiling surface. The configuration and structure of the fire extinguisher 10 are arbitrary, but for example, it is equipped with a partition means, an extinguishing agent flow path, and a discharge port, and as an example, it is equipped with a partition 12 as the partition 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.

(partition)
The partition 12 includes 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 device 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.

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 other side to be seen, but other sizes are also available, including those with a window such as frosted glass in one part, and are optional.

More specifically, as shown in FIG. 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 panel member 14 by, for example, bolts 31. As shown in FIG. 4(B), the panel member 14 is fixed in the thickness direction by gluing or the like with spacers 33 interposed between the first panel 30 and the second panel 32 at the four corners, forming an internal space between the first panel 30 and the second panel 32.

(Distribution route of fire extinguishing agent)
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 while the configuration and structure thereof are arbitrary, for example, it is arranged so as to form a four-stage ladder shape in the vertical direction (height direction), with the topmost first stage being a linear flow path, and the second to fourth stages having, for example, seven discharge ports 22 arranged therein. 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.

(Fire extinguishing agent discharge pipe)
The 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.

Here, by arranging extinguishing agent discharge pipes 20 at each stage of the ladder-shaped extinguishing agent flow path 18, the horizontally arranged discharge port row is treated as 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 overall discharge port row.

Extinguishing agent flow paths 18 are connected to both ends of the extinguishing agent discharge pipe 20 so that 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 align the discharge pattern (angular distribution) and discharge amount within the same row.

5, the extinguishing agent discharge pipe 20 has a pipe body 34, both ends of which are closed to provide piping connection ports 38, and a plurality of nozzle members 36 are arranged in a straight line and screwed and fixed in the axial direction of the outer periphery of the pipe body 34. 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.

The diameter of the discharge port 22 provided in the extinguishing agent discharge pipe 20 is, for example, about 3 to 4 millimeters. A diameter of about 3 to 4 millimeters corresponds to the diameter of one of the multiple discharge holes formed in a shower head that uses tap water. Therefore, a tap water discharge pattern equivalent to one of the holes in 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.

When the nozzle member 36 is provided with a straight through hole, the discharge port 22 has a relatively narrow-angle discharge pattern, but 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.

In this embodiment, the central axis of the nozzle member 36 (dotted line in FIG. 5C) is perpendicular to the panel surface, but this is not limited to this. For example, the directionality of the extinguishing agent release can be adjusted by adjusting the inclination angle of the central axis relative to the panel surface.

The first panel 30 in FIG. 4(B) has a through hole 35 formed corresponding to the discharge port 22 of the panel member 14 shown in FIG. 3, and the discharge port 22 is formed by fitting the nozzle member 36 provided on the extinguishing agent discharge pipe 20 into the through hole 35, so that the extinguishing agent 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.

The extinguishing agent flow path 18 is connected to both ends of the extinguishing agent discharge pipe 20 arranged inside the panel member 14. In this case, the connection structure is arbitrary, but for example, a rubber hose or 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 using a T-joint.

Alternatively, the extinguishing agent discharge pipe 20 and the extinguishing agent flow path 18 may be prepared as a separate assembly, which may then be placed between the first panel 30 and the second panel 32 via a spacer 33 and assembled together as shown in FIG. 4(B).

[b. Fire extinguishing equipment with a vertically arranged 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 edge, upper end edge, and right end edge of the panel member 14 between the extinguishant supply ports 24a, 24b.

In this case, the extinguishing agent supply flow passage 18 is not connected to both the upper and lower ends of the extinguishing agent discharge pipe 20, but since there is almost no pressure loss due to the difference in head when 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, the discharge pressure of the multiple discharge ports 22 arranged vertically can be made approximately uniform, and the discharge pattern (angle distribution) and discharge amount can be made uniform.

[c. Overview of fire extinguishing equipment]
Next, an overview will be given of the fire extinguishing system of this embodiment using the fire extinguisher 10. 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.

For the fire extinguisher 10, an extinguishing agent pipe 25 drawn from an extinguishing agent supply source 26 via a pipe opening/closing valve 28 functioning as a pipe opening/closing means is connected to an extinguishing agent supply port 24a, which supplies extinguishing agent to the extinguishing agent distribution path 18 inside the partition 12 and enables the extinguishing agent to be discharged 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.

[d. Fire extinguishing equipment using water piping]
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, the extinguishing agent pipe 25, the remote opening and closing valve 45, the manual opening and closing valve 46, and the water pipe 47. The fire extinguishing device 10 is placed at a desired position in a room that is a target area 11, and the panel surface (boundary surface) on one side of the panel member 14 where the discharge port 22 is located is directed toward the area to be extinguished.

A fire detector 44 is placed in the target area 11 as a fire detection device 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 pipe 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 pipe 25 is connected to a water pipe 47 via a parallel connection of the remote on-off valve 45 and a manual on-off valve 46 that function as a pipe opening and closing means.

The extinguishing agent piping 25 should be a normal piping with rigidity from the water piping 25 to the lead-in portion of the target area 11, and within the target area 11, it should be a flexible piping, such as a pressure-resistant hose made of rubber or vinyl, so that it can flexibly respond to the arrangement and rearrangement of the partitions 12.

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 extinguisher 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.

On one side of the panel member 14 provided on the partition 12, a row of outlets, for example 3 vertical x 7 horizontal, is provided, 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 outlet 22 is positioned, the farther it will reach, covering a part or all of the area on the discharge side as the discharge range.

In addition, if a table or other furniture is placed within the release range, the water discharged from the outlet 22 of the partition 12 will reach underneath the table. If you wish to spray water onto the ceiling, you can point part of the topmost outlet 22 upwards to wet the ceiling and prevent the fire from spreading.

The extinguishing agent, tap water, is discharged from multiple outlets 22 located in various places on the panel surface of the partition 12. This is a surface discharge, and unlike conventional point discharges where a sprinkler head is placed on the ceiling surface and only one point is discharged, a wider discharge area (spraying area) can be covered with the same amount of discharge. Also, because tap water is sprayed from the side at the location where the fire started, the extinguishing agent can reach places that are hidden from above, such as under tables and desks. As a result, it is possible to suppress and extinguish a fire with a smaller amount of extinguishing agent discharged.

[e. Fire extinguishing equipment with a fire extinguisher connected]
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 supplying device, for example, a fire extinguisher 48, is used as an extinguishing agent supply source for the fire extinguisher 10. The configuration and arrangement of this fire extinguishing system are arbitrary, but for example, it includes the fire extinguisher 10, an extinguishant pipe 25, a fire extinguisher 48, and a fire extinguisher connection part 56. The fire extinguisher 48 supplies a predetermined extinguishing agent, for example, a powder fire extinguisher or a reinforced liquid fire extinguisher, to the fire extinguisher 10, and discharges the extinguishant 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.

The extinguishing agent piping 25 is flexible piping, such as a pressure-resistant hose made of rubber or vinyl, allowing for flexible placement and rearrangement of the partition 12 and the fire extinguisher 48. The extinguisher 48 has a main container filled with extinguishing agent under pressure, and when the safety pin 52 is removed and the lever 54 is pressed down, the container opens and the extinguishing agent is released from the hose 50.

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

In this embodiment, the extinguisher nozzle 58 is a nozzle that is attached to the end of the hose of the fire extinguisher 48, and a separately prepared fire extinguisher nozzle 58 is attached to the end of the hose, but the present invention is not limited to this.

Figure 9 shows an example of a fire extinguisher connector 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 single touch. 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 pipe 25, making it possible to attach and detach the hose 50 of the fire extinguisher 48 to the extinguishant pipe 25 with a single touch.

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 arrow in the figure.

The fire extinguisher 10 using the partition 12 of this embodiment has the structure shown in Figures 1 to 4, but it may also be the fire extinguisher 10 (10a) shown in Figure 6.

In addition, since the fire extinguisher 48 is placed in a designated 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 and without panicking perform the opening operation by removing the safety pin 52 of the fire extinguisher 48 and squeezing the lever 54.

In addition, the discharge of extinguishant by 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 discharge of extinguishant can be continued by removing the fire extinguisher nozzle 58 from the fire extinguisher connection port 60 of the fire extinguisher connection part 56 and replacing it 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 enabling reliable suppression and extinguishing of the fire. Note that it is also possible to continue discharging extinguishant without replacing a used fire extinguisher by providing a fire extinguisher connection part to which a plurality of fire extinguishers 48 can be connected, or by providing fire extinguisher connection parts at a plurality of places on the extinguisher discharge pipe 20 and connecting a plurality of fire extinguishers 48 to the extinguisher discharge pipe 20 in advance.

In addition, if a fire occurs in another location (where the fire extinguishing device 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 and reducing maintenance costs.

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

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

Furthermore, the fire extinguisher 48 is connected to a pipe branching off from one end of the extinguishing agent pipe 25 between the remote on-off valve 45 and the manual on-off valve 46 (point A in the figure) via a check valve 68 serving as backflow prevention means for preventing backflow of tap water from the extinguishing agent pipe 25 side to the fire extinguisher 48 side. Furthermore, a fire extinguisher connecting part 56 is provided as a connecting means for detachably connecting the fire extinguisher 48 to the fire extinguisher pipe 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.

The water pipe 47 is connected to the connection part (point A in the figure) of the check valve 68 of the extinguishing agent pipe 25 via a gate valve 66, and a remote opening/closing valve 45 and a manual opening/closing valve 46 that function as remote and manual control valves that open and close the flow path leading from the water pipe 47 to the extinguishing agent pipe 25 are connected in parallel between the gate valve 66 and the connection part (point A in the figure) of the check valve 68. The check valve 68 prevents tap water from flowing into the fire extinguisher connection part 56 when tap water is supplied from the water pipe 47 to the extinguishing agent pipe 25.

The extinguishing agent piping 25 is a normal piping having rigidity up to the retraction part of the target area 11 beyond the connection part (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 a flexible pressure-resistant hose made of, for example, rubber or vinyl, so that it can flexibly respond to the arrangement and rearrangement of the partition 12.

A fire detector 44 is placed in the target area 11 as fire detection equipment and is connected to a receiver 42. A fire warning light 43 is placed near the location of the fire extinguisher 48 and is connected to the receiver 42. A remote opening and closing valve 45 is also connected to the receiver 42.

The receiver 42 can be set to an automatic extinguishing mode or a manual extinguishing mode. The automatic extinguishing mode is set, for example, during nighttime hours, and extinguishing agent (tap water) is released in conjunction with fire detection by the fire detector 44 (fire alarm of the receiver). The manual extinguishing mode is set, for example, during daytime hours, and extinguishing agent is released by operating the fire extinguisher 48 or manual opening and closing valve 45. In addition to switching between the manual extinguishing mode and the automatic extinguishing mode between daytime and nighttime hours 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.

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.

When the relevant personnel become aware of a fire, they go to the location where the fire has broken out, 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, which then releases a powder fire extinguishing agent or the like from multiple discharge ports 22 provided in various places on the panel surface of the partition 12, suppressing and extinguishing the fire.

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 extinguishing device 10, and the tap water is discharged from the multiple discharge ports 22 provided in various locations on the panel surface of the partition 12 to suppress and extinguish the fire. The tap water is discharged after the fire has been suppressed by the discharge of the extinguisher 48, and there is no time constraint on the discharge of the tap water, making it possible to reliably extinguish the fire.

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 and closing valve 45 to open it, supplying tap water to the fire extinguishing device 10 and discharging 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.

Even in the automatic extinguishing mode, for example, if relevant personnel who have rushed to the scene after receiving a fire report find that the fire is not weakening, a predetermined operation can be performed on the receiver 42 to close the remote opening/closing valve 45 , for example, to cancel the automatic extinguishing mode and switch to manual extinguishing mode, and then the safety pin 52 of the fire extinguisher 48 can be removed and the lever 54 can be pushed down to open the extinguisher, supplying extinguishing agent from the extinguisher 48 to the fire extinguishing device 10 and discharging the extinguishing agent from the discharge ports 22 located in various places on the panel surface of the partition 12, thereby making it possible to suppress and extinguish the fire.

In this way, after the extinguishing agent has been released from the fire extinguisher 48, the manual on-off valve 46 can be opened again to switch back to releasing tap water.

[g. Connected fire extinguishing appliances]
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).

The partitions 12 (12-1, 12-2) of the fire extinguishing apparatus 10 arranged in a connected manner have the structure shown in Figures 1 to 5 or 6.

For the partitions 12 (12-1, 12-2) of the fire extinguisher 10 arranged in a connected manner, an extinguishing agent pipe 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 pipe such as a hose, and further, the extinguishing agent supply port 24b of the partition 12-2 is closed.

When the partitions 12 (12-1, 12-2) of two fire extinguishing devices 10 are connected and arranged in the target area 11 in this way, in the event of a fire, each of the multiple partitions 12 (12-1, 12-2) will release extinguishing agent 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.

When three or more disaster prevention devices 10 are arranged in succession, the extinguishing agent supply port 24a of one of the partition devices 12 located in the middle is connected to the extinguishing agent piping from another partition device located in front, and the extinguishing agent supply port 24b of the other is connected to the extinguishing agent piping to another partition device located in the back.

[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.

As shown in FIG. 12(A), when partitions 12 (12-1, 12-2) of 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 of the panel members 14 of the partitions 12 (12-1, 12-2).

The three-way switching valves 90a, 90b have three ports a, b, and c, and allow switching operations to communicate between ports a and b, between ports b and d, or between ports a and c. 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 horizontal direction (left-right direction) via the three-way switching valves 90a, 90b.

When spraying extinguishing agent from both connected partitions 12-1 and 12-2, the three-way valves 90a and 90b provided on partitions 12 (12-1 and 12-2) are switched as shown in Figures 12 (B) to (D), respectively.

The three-way switching valve 90a on the side of the extinguishing agent supply port 24a to which the extinguishing agent piping 25 of the partition 12-1 is connected communicates between ports a and b as shown in FIG. 12(B), and the extinguishing agent that flows in from the extinguishing agent piping 25 via the extinguishing agent supply port 24a flows out to the extinguishing agent flow path 18-1 located above.

As shown in FIG. 12(C), the three-way valve 90b on the extinguishing agent supply port 24b side of partition 12-1 connects ports b and c, and allows the extinguishing agent flowing 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.

The three-way valve 90a on the side of the extinguishing agent supply port 24a of the second partition 12-2, to which the extinguishing agent supply port 24a of the partition 12-1 is connected, communicates between ports a and b as shown in FIG. 12(D), and allows the extinguishing agent that flows in from the partition 12-1 via the extinguishing agent supply port 24a to flow out to the extinguishing agent flow path 18-2 located above.

Furthermore, 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 c as shown in FIG. 12(E), thereby closing the flow path to the extinguishing agent supply port 24b of the extinguishing agent supply flow path 18-2 located above.

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 flow path 18-1 of partition 12-1, and extinguishing agent is not supplied to the second partition 12-2.

When spraying extinguishing agent only from the second partition 12-2, the three-way 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-c communicate with each other and port b is closed, as in FIG. 12(E), and the extinguishing agent supplied from the extinguishing agent piping 25 is bypassed by the bypass flow path 19 of partition 12-1 and supplied to the next partition 12-2.

The three-way switching valve 90a on the extinguishing agent supply port 24a side of partition 12-2 is switched to a position that connects ports a and b, as shown in FIG. 12(D). Additionally, the three-way switching valve 90b on the extinguishing agent supply port 24b side is switched to a position that connects ports a and c and closes port b, as shown in FIG. 12(E). This allows extinguishing agent to be supplied to partition 12-2 via partition 12-1, and extinguishing agent to be sprayed only from partition 12-2.

[i. Fire extinguishing equipment forming a partition]
An embodiment of a fire extinguisher in which 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 plurality of partitions 12 (12-1 to 12-11) are connected and arranged in a target area 11 to form, for example, a rectangular shape, and a door panel 78 is arranged in a predetermined position to form a partitioned section 80 to be used, for example, as a conference room or a reception room. 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.

Therefore, if a fire breaks out in the partitioned area 80 separated by the partitions 12 (12-1 to 12-11), the fire extinguishing device 10 (10a) can be used to release a fire extinguishing agent into the partitioned area 80 from the partition 12 (12-2), thereby suppressing and extinguishing the fire.

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

[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 equipped 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.

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 to an extinguishant supply port 24c provided on the panel surface of the nearby panel member 14 via a fire extinguisher connection part 86, making it possible to supply extinguishant to the extinguishant flow path 18. The fire extinguisher connection part 86 has a connection joint structure similar to that shown in FIG. 9, for example.

The fire extinguisher 10 (10b) of this embodiment can be easily moved using the casters 82, and by integrating the fire extinguisher 48 into the partition 12, it is possible to use the fire extinguisher 10 (10b) by moving the partition 12 to any position in the target area 11 and placing it there.

[k. Fire extinguishing device with outlet located on 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.

More specifically, the extinguishing agent supply passage 18 shown by the dotted line is arranged inside the middle frame 16b, upper frame 16a, and 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, and an extinguishing agent discharge pipe 20 that constitutes part of the extinguishing agent flow path 18 is arranged inside the upper frame 16a, which is located at a high position, and the extinguishing agent discharge pipe 20 has multiple discharge ports 22 arranged in a horizontal line as shown in Figure 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 serve as discharge points are arranged in a horizontal line, and the fire is suppressed and extinguished by linear discharge of extinguishing agent.

In addition, in the fire extinguisher 10 (10c) of this embodiment, in addition to the discharge port 22 located in the upper frame 16a of the partition 12, multiple discharge ports may be located in various places on the panel surface of the panel member 14.

[l. Modifications of the present invention]
