Description

[Technical field]

[0001] The present invention relates to a fire extinguishing apparatus installed in an ordinary house, an apartment building, a group home, etc., for suppressing and extinguishing a fire, and to a fire extinguishing facility installed in an automated warehouse, etc., for suppressing and extinguishing a fire. [Background technology]

[0002] Conventionally, fire extinguishers have been installed as fire extinguishing equipment in ordinary homes, apartment buildings, group homes for the elderly, etc. Also, sprinkler fire extinguishing equipment is known that uses tap water as a water source and releases tap water from a sprinkler head when a fire occurs to suppress and extinguish the fire (Patent Documents 1 and 2).

[0003] Furthermore, in an automated warehouse, a stacker crane is used to carry goods into and store them on a rack shelf (storage shelf), and to carry the stored goods out. Known fire extinguishing equipment for an automated warehouse includes equipment in which a sprinkler is provided on the lifting gauge of a stacker crane, which is transported to the location of a fire on the rack shelf and releases a fire extinguishing agent (Patent Document 3), equipment in which a fire extinguishing unit equipped with a fire extinguishing agent tank and a nozzle is transported by a stacker crane to the location of a fire on the rack shelf and releases a fire extinguishing agent (Patent Document 4), equipment in which a water discharge nozzle is provided on the lifting platform of a stacker crane, a hose from a fire extinguishing agent supply source is connected, which is transported to the location of a fire on the rack shelf and releases a fire extinguishing agent (Patent Document 5), and the like.

[0004] [Patent Document 1] JP 2012-152261 A [Patent Document 2] JP 2012-179330 A [Patent Document 3] Japanese Patent Application Publication No. 9-221201 [Patent Document 4] JP 2012-111620 A [Patent Document 5] JP 2011-121771 A [Patent Document 6] Japanese Utility Model Application Publication No. 53-166598 [Patent Document 7] Japanese Patent Application Publication No. 57-017666 Summary of the Invention [Problem to be solved by the invention]

[0005] However, when fire extinguishers are installed, it may be difficult to quickly and reliably put out a fire when it occurs, as many people may not know where the extinguishers are located or may not be familiar with using them. Also, while extinguishing a fire is being carried out, there is a risk that personnel who can evacuate vulnerable people quickly and safely may not be available, so if evacuation guidance is prioritized, it may not be possible to use the extinguishers effectively and reliably.

[0006] In addition, sprinkler fire extinguishing equipment that uses tap water activates when the temperature rise caused by hot air currents meets the activation conditions, and does not activate until the scale of the fire has grown to a certain extent, so there is a problem that it is not necessarily possible to start extinguishing the fire early. Also, sprinkler heads release water for extinguishing locally from the installation point, and when the amount of water released per unit time is restricted, as with tap water, it is difficult to ensure a sufficient range and amount of water released, and there is a possibility that the fire cannot be sufficiently suppressed and extinguished.

[0007] Furthermore, in conventional fire extinguishing systems for automated warehouses, a stacker crane is used to transport a nozzle, for example, to the location of the fire on the rack shelf and release the extinguishing agent, but this series of controls takes time, and in the meantime the fire can spread, meaning it may be too late to put out the initial fire.

[0008] Furthermore, if fire extinguishing agent is released from a nozzle at the location of a fire on a rack shelf, it will splash around and wet the stored items, resulting in greater water damage.

[0009] An object of the present invention is to provide a fire extinguishing device and a fire extinguishing facility that are easy to install and efficiently suppress and extinguish a fire with a small amount of discharge.

[0010] Another object of the present invention is to provide a fire extinguishing system for warehouses that can reliably suppress and extinguish fires while minimizing water damage, and is targeted at automated warehouses and the like where items are brought into storage shelves for storage and then removed from the shelves for management.

[0031] (Warehouse fire extinguishing equipment) The present invention relates to a fire extinguishing system for a warehouse using the above-mentioned fire extinguishing device, The warehouse is A storage shelf having a plurality of storage sections arranged therein; A conveying means for conveying the article into and out of the storage section; Equipped with The fire extinguisher is characterized in that it is installed to separate a predetermined target compartment including the location of a fire in the storage shelf and release a fire extinguishing agent into the target compartment.

[0032] (Target area) The storage shelf has multiple storage compartments, The predetermined target section of the storage shelf is a storage section (rack) or a row of storage sections (row of racks), The fire extinguishing apparatus is provided corresponding to a storage section or a storage section row, and when a fire occurs in the storage section or the storage section row, the fire extinguishing apparatus separates the storage section or the storage section row and releases a fire extinguishing agent.

[0033] (Placement of fire extinguishing equipment) The storage section or storage section row has a closed structural surface and an open opening surface, The fire extinguishing equipment is provided in correspondence with the open surface of the storage unit or the row of storage units.

[0034] (Fire detection and sheet deployment) Each target section is provided with a fire detection means for detecting a fire, When a fire is detected by the fire detection means, a fire extinguishing agent is supplied to the sheet deployment means of the fire extinguisher corresponding to the target compartment where the fire was detected, and the sheet is released from the non-deployed state and deployed. Effect of the Invention

[0035] (Basic Effects of Fire Extinguishing Equipment) In the fire extinguisher of the present invention, a number of discharge ports are arranged in various locations on, for example, one side of a sheet placed in a room or the like to serve as a protected compartment, facing the protected compartment, and when a fire occurs, extinguishing agent is released from the multiple discharge ports, thereby achieving surface release. This ensures a wider release range than the point release of conventional sprinkler beds, which release the agent at the installation location, and by reducing the number of areas that are obstructed by water spraying, makes it possible to suppress and extinguish a fire with a small amount of extinguishing agent released.

[0036] Here, "area release" refers to multiple release ports (release points) arranged at various locations on the sheet surface, thereby releasing the extinguishing agent over a surface area from multiple locations, i.e., the extinguishing agent is released from the release ports arranged at various locations on the sheet surface, thereby releasing the extinguishing agent over a wide area of ​​the sheet surface. "Point release" refers to the release of the extinguishing agent from a single point, due to the presence of a release port (release point) at one location (installation location). "Line release" refers to the linear release of extinguishing agent from multiple release ports arranged in a straight line.

[0037] In addition, the sheet is sized to correspond to the size of openings in the protected area, such as doors, walls, and ceiling surfaces, and by reducing the amount of extinguishing agent discharged from each outlet, it is possible to discharge a smaller amount of extinguishing agent overall than the amount of water sprayed from a sprinkler head, and with relatively little pressure, to every corner of the target space, making it possible to efficiently suppress and extinguish fires within a specified area in a short period of time, with little impact on the outside, and furthermore, the disaster prevention device can be made lightweight and simple.

[0038] Furthermore, if the sheet is deployed from above to below (deployed along the side of the protected area) and used as an outlet that mainly releases extinguishing agent in a direction perpendicular to the sheet surface, the extinguishing agent will be released sideways (from the side of the protected area, for example a room, into the room), allowing the extinguishing agent to reach locations that are hidden from above, such as under tables or desks placed in the room, etc., thereby ensuring the suppression and extinguishing of fires.

[0039] Here, "fire suppression and extinguishing" refers to a combination of the concept of suppressing a fire and another concept of extinguishing a fire. For example, fire suppression is the concept of suppressing the spread of a fire, the burning speed of a fire, or the scale of a fire, while fire extinguishing is the concept of putting out the fire. Of course, it also includes cases where only one of these is done.

[0040] (Effect of sheet deployment in the event of a fire) In addition, since the sheet equipped with a fire extinguishing agent flow path and a discharge outlet is flexible, under normal circumstances, the sheet is placed in a non-deployed state, for example in a rolled-up state, at the upper part of the wall of a room at a specified position on the boundary of the protected area, thereby requiring less installation space.

[0041] In addition, when a fire occurs, by releasing the sheet from its holding position, the other end of the sheet, which has one fixed end, falls downward while unfolding from above to below, and extinguishing agent is released from outlets located in various places on the unfolded sheet, making it possible to suppress the fire by extinguishing it.

[0042] (Effect of sheet deployment action due to supply of extinguishing agent) In addition, the sheet can be deployed by releasing the undeployed state using the pressure of the extinguishing agent supplied in the event of a fire as a driving source. Also, since no electrical release operation is required, the sheet can be deployed reliably and the extinguishing agent can be released even in the event of a power outage.

[0043] (Effect of fixed installation of deployment sheet) In addition, the sheet may be installed in an expanded (spread out) state from the beginning on the wall of a room to be protected, and in the event of a fire, the extinguishing agent can be released over a wide area from multiple release ports located in various parts of the sheet, making it possible to extinguish the fire and suppress it.

[0044] (Effect of seat structure 1) In addition, by configuring the sheet so that a collapsible and deformable sheet piping with an extinguishing agent supply inlet and discharge outlet is placed between two cover sheets (first cover sheet and second cover sheet), a flexible sheet with an extinguishing agent flow path and a discharge outlet can be manufactured simply, easily and at low cost.

[0045] (Effect of seat structure 2) Furthermore, since the first cover sheet, the first waterproof sheet, the second waterproof sheet and the second cover sheet can be sewn together in a stacked state to form an extinguishing agent flow path with an extinguishing agent supply port and release port, the formation of the extinguishing agent flow path and the integration of the stacked sheets are achieved simultaneously by sewing, making it possible to more simply and easily create a flexible sheet with an extinguishing agent flow path and a release port, and since mass production is also easy, manufacturing costs can be further reduced.

[0046] In addition, the extinguishing agent flow path can be simply and easily formed into any desired path pattern by, for example, sewing with a sewing machine or bonding with an adhesive.

[0047] (Cover sheet effect) In addition, the cover sheets (first cover sheet, second cover sheet) have fire prevention, fire resistance, heat resistance, heat insulation, flame insulation, or smoke insulation properties, so they can continue to release fire extinguishing agent without being burned even when exposed to heat or flames from a fire, and when they are installed and deployed at openings such as entrances and exits that form the boundary of a protected area, they can prevent the spread of fire and ensure an escape route by providing flame, heat, and smoke insulation to the outside of the protected area. In addition, the flexibility of the cloth-like body makes it possible to evacuate from inside the protected area to the outside even after the sheet is deployed.

[0048] (Effect of wetting the sheet with fire extinguishing agent) In addition, when creating a fire extinguishing agent flow path by sewing or adhesive, for example, the fire extinguishing agent can be caused to flow outside the fire extinguishing agent flow path as a coolant to wet the sheet, thereby improving the flame, smoke and heat insulation properties of the sheet.

[0049] (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 row element in which multiple discharge ports are arranged along, for example, the horizontal direction of the sheet, 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.

[0050] (Effect of the location of fire extinguishing equipment) In addition, the fire extinguishing equipment can be simply and easily installed and used in any position as needed, such as a room entrance, wall, window, or ceiling surface, which is the boundary of the protected area, with the sheet in an undeployed or deployed state, for example by positioning the sheet surface along the boundary surface of the boundary when the sheet is in an undeployed state, making it possible to install an optimal fire extinguishing equipment that is suited to the usage of the room.

[0051] (Effect of pressure buffering measures) In addition, when the extinguisher is opened to supply the extinguishant to the extinguishant flow path, the accumulated pressure of the extinguisher is high, for example, 0.7 MPa to 0.98 MPa, and if high-pressure extinguishant is added to the extinguisher flow path of the fire extinguisher when the extinguisher is opened, there is a possibility of damage, etc. Therefore, by providing a buffer area (buffer area) as a pressure buffer means on the inlet side of the extinguishant flow path, the increase (or increase rate) of the extinguishant supply pressure from the fire extinguisher is kept below a predetermined level to prevent damage to the extinguishant flow path and the discharge port. In addition, by providing a second pressure buffer means such as a tank or an orifice at the extinguishant supply port, the increase (or increase rate) of the extinguishant supply pressure from the fire extinguisher is similarly kept below a predetermined level to prevent damage to the extinguishant flow path and the discharge port.

[0052] (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.

[0053] (Effects of fire extinguishing equipment 2 using fire extinguishers) In addition, by connecting a fire extinguishing agent supply device, such as 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, such as a powder fire extinguishing agent or a reinforced liquid fire extinguishing agent, from the fire extinguishing device's outlet into the protected compartment, it is possible to effectively suppress and extinguish the fire.

[0054] In addition, even if a person is unfamiliar with handling 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 a room that serves as a protected area, and pulling the lever to open the extinguisher, high-pressure fire extinguishing agent, such as a powder fire extinguishing agent, can be supplied to the fire extinguishing device installed in the room, and the powder fire extinguishing agent can be released over a wide area from the discharge port of the fire extinguisher at the same time as the sheet is deployed, making it possible to suppress and extinguish a fire effectively in a short period of time.

[0055] (Effects of fire extinguishing equipment 3 that uses fire extinguishers and water piping in combination) In addition to the effects of the fire extinguishing system 1 using water piping and the fire extinguishing system 2 using a fire extinguisher described above, when a fire breaks out, an extinguishing agent supplying device, for example, a fire extinguisher, is opened to release an extinguishing agent, for example, a powder fire extinguishing agent or a reinforced liquid fire extinguishing agent, from the discharge port of the fire extinguisher into the protected compartment, thereby carrying out initial extinguishing of the fire; the duration of the discharge of the extinguishing agent by the fire extinguisher is short, for example, a dozen seconds, but if the fire is not sufficiently suppressed and extinguished, tap water is discharged from the discharge port into the protected compartment by opening the piping opening / closing means, thereby continuing to suppress and extinguish the fire; and since there is no time constraint on the discharge of tap water, it is possible to reliably extinguish a fire that has been suppressed by the discharge of the extinguishant from the fire extinguisher.

[0056] (Effect of the configuration of the piping opening and closing means) In addition, in fire extinguishing equipment 1 or 3, the remote on-off valve can be opened by remote control based on a control signal from the fire detection equipment when a fire occurs in the protected area, making it possible to release extinguishing agent from the outlet of the fire extinguishing equipment in conjunction with fire detection, and also making it possible to release extinguishing agent from the fire extinguishing equipment by manually opening the manual on-off valve.

[0057] (Effect of connecting means for fire extinguisher) In addition, since the fire extinguisher is detachably connected to the extinguishant piping by the connecting means, when the fire extinguisher is finished being used, it can be replaced with an unused fire extinguisher as necessary, so that the discharge of the fire extinguishant can be continued and reliable suppression and extinguishing can be achieved. Furthermore, if multiple connecting means with a check valve structure are provided and a fire extinguisher is connected to each of them, the work of detaching and replacing the fire extinguisher can be eliminated, and the discharge of the fire extinguishant can be continued quickly, enabling reliable suppression and extinguishing.

[0058] 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, meaning 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.

[0059] (Effect of the second pressure buffer in the extinguishing agent supply system) In addition, in the fire extinguishing equipment 2 or 3, a second pressure buffer means is provided in the connecting means of the extinguishing agent supply system or in the extinguishing agent piping, so that the increase (or rate of increase) in the extinguishing agent supply pressure from the fire extinguisher is kept below a predetermined value, thereby preventing damage to the extinguishing agent distribution path or discharge outlet.

[0060] (Effectiveness of warehouse fire extinguishing equipment) According to the warehouse fire extinguishing system of the present invention, for example, if an item stored in any storage section of a storage shelf ignites and causes a fire, a fire extinguishing sheet installed on the storage shelf is deployed to partition and block the opening surface corresponding to the boundary of a specified target section including the location of the fire on the storage shelf, and extinguishing agent is released into the target section from multiple release ports installed in various places on the deployed sheet, which allows for more efficient spraying over a wider area within the target section than the point release of a conventional sprinkler bed, which releases the agent at the installation location, and reduces water damage outside the target section (loss and damage caused by the extinguishing agent being sprayed), making it possible, overall, to suppress and extinguish the fire with less extinguishing agent released than before.

[0061] In addition, by deploying a sheet of fire extinguishing equipment installed on a storage shelf and partitioning off and sealing the opening of a specified target compartment including the location of the fire on the storage shelf, it is possible to prevent the spread of fire and smoke by blocking flames, smoke, and heat from within the target compartment to the surrounding area, and the synergistic effect of releasing extinguishing agent into the target compartment from openings in various places on the sheet can further enhance the suppression and extinguishing performance.Furthermore, the extinguishing agent released into the partitioned compartment can be prevented from dissipating or being released into the surrounding area, thereby reducing water damage to items stored in the vicinity, for example.

[0062] In addition, because the fire extinguishing equipment is installed on the storage shelves, there is no need to transport a fire extinguishing nozzle to the location of the fire using a transport means such as a stacker crane, as is the case with conventional warehouse fire extinguishing equipment, and the extinguishing agent can be released in a short time after the fire breaks out to suppress and extinguish the fire.

[0063] (Effect of target area) In addition, the fire extinguishing equipment is provided to correspond to the opening surfaces, excluding the structural surfaces, of the target storage section (rack) or storage section row (rack row) consisting of multiple storage sections. When a fire breaks out in a storage section or storage section row, the opening surfaces of the storage section or storage section row are partitioned off, so that, together with the structural surfaces, the storage section or storage section row is blocked off almost without any gaps in all directions as seen from the fire source. In this state, fire extinguishing agent can be released inside, making it possible to efficiently suppress and extinguish the fire.

[0064] (Fire detection and sheet deployment effects) In addition, the sheet deployment means provided on the fire extinguisher normally keeps the sheet in an undeployed state, so as not to hinder the transport means from loading or unloading items into or from the storage section of the storage shelf. Meanwhile, in the event of a fire, the undeployed state of the sheet is released and deployed by supplying extinguishing agent to the fire extinguisher in the target compartment where a fire has been detected by the fire detection means, and the extinguishing agent is released while the target compartment where the fire is occurring is partitioned off and sealed, making it possible to quickly and reliably suppress and extinguish the fire.

[0068] [a. Basic Concept of the Embodiment] First, the basic concept of the embodiment will be described. Note that the present invention is not limited to the following embodiment.

[0069] The embodiment generally relates to a fire extinguishing device and a fire extinguishing facility. The "fire extinguishing device" is a device that suppresses and extinguishes a fire by discharging or scattering a fire extinguishing agent. Here, the "protected area" is an area in which the fire extinguishing device is installed, and includes, for example, an external area of ​​a building and an internal area within a building, and the internal area within a building is a concept that includes, for example, a room, a corridor, a staircase, etc. of a building.

[0070] The fire extinguisher according to the embodiment includes a sheet, an extinguishing agent flow path, an extinguishing agent supply port, and a discharge port. The "sheet" is, for example, a flexible, thin, wide object that can be used to cover or encase something, and is a concept that includes, for example, a cloth-like body that can be held in a non-deployed state and released from the non-deployed state to be in a deployed state.

[0071] The term "extinguishing agent flow path" refers to a path provided in the sheet through which the extinguishing agent flows, and is a concept including, for example, a sheet pipe disposed between the cloth bodies. Note that the "sheet pipe" refers to, for example, a flexible pipe that can be crushed and deformed and expands when an extinguishing agent flows through it.

[0072] The term "extinguishing agent supply port" refers to an inlet for supplying an extinguishing agent to an extinguishing agent flow path provided in the sheet, and is a concept that includes, for example, a connection port for an extinguishing agent pipe.

[0073] In addition, the "discharge port" is an exit port for the extinguishing agent supplied from the extinguishing agent supply port to the extinguishing agent distribution path, and discharges the extinguishing agent from various locations on at least one side of the sheet, for example, an opening that discharges the extinguishing agent from multiple discharge ports arranged at various locations on one side of the sheet in the event of a fire.

[0074] The fire extinguisher also includes a sheet deployment means. Here, the "sheet deployment means" refers to a means for normally holding a sheet in an undeployed state at a predetermined position on the boundary of a protected area, and releasing and deploying the sheet when a fire breaks out. For example, normally, the sheet is held in a rolled-up, undeployed state at an opening on the boundary of a protected area, for example, on the upper ceiling side of an entrance to a room, and when a fire breaks out, the sheet is released and deployed, with one end edge (upper end edge) fixed and the other end edge (lower end edge) dropping under its own weight and deploying downward to close the opening.

[0075] 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.

[0076] A fire extinguishing system using a fire extinguishing appliance includes an extinguishing agent piping and an extinguishing agent supply source. Here, the term "extinguishing agent piping" refers to piping that supplies an 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, the term "extinguishing agent supply source" refers to a source that supplies an extinguishing agent to the extinguishing agent piping, and is a concept that includes, for example, water supply piping that supplies tap water, a pressurized water supply device equipped with a pump that supplies extinguishing water, a water storage tank, an elevated water tank, and extinguisher or other extinguishing agent supply appliances.

[0077] In the following description, first, specific details of an embodiment of a fire extinguishing device and a fire extinguishing system will be described for a case where the "protected area" is a "room in a building" and the "extinguishing agent supply source" is a "water pipe" and / or a "fire extinguisher". Next, the basic concept and specific details of an embodiment of a fire extinguishing system for a warehouse using a fire extinguisher will be described.

[0078] [b. Specific details of the embodiment] The specific contents of the embodiment of the fire extinguishing device and the fire extinguishing system will be described below.

[0079] (b1. Configuration of fire extinguishing equipment and fire extinguishing facilities) As shown in Fig. 1, the fire extinguisher 12 of this embodiment is installed at the boundary of a room that becomes a protected area 10, for example, in a group home or the like, for example, above an entrance 11. Normally, the fire extinguisher 12 holds a sheet 28 made of a flexible cloth-like body in a non-expanded state, for example, rolled up, in a main body 62, and the sheet 28 is provided with a fire extinguishing agent flow path and a plurality of discharge ports. Here, for the protected area 10 in Fig. 1, as shown in the figure, the vertical direction with the ceiling surface on which the fire detector 14 is installed facing upward is called the vertical direction or height direction, the direction that connects the left and right wall surfaces as viewed from the entrance 11 (opening) that becomes the boundary of the room, perpendicular to the vertical direction, is called the left-right direction or horizontal direction, and the direction from the entrance 11 toward the inside of the room is called the depth direction.

[0080] In the protected compartment 10, a fire detector 14 is connected to a receiver 16 as a fire detection facility. To the fire extinguisher 12, a fire extinguishing agent pipe 20 is connected from a water supply pipe 18 of the water supply facility via a gate valve 25. A remote on-off valve 24 and a manual on-off valve 26 are connected in parallel to the fire extinguisher pipe 20 as pipe opening and closing means for opening and closing the pipe flow path by remote control or manually. Here, the fire extinguishing facility of this embodiment is composed of the fire extinguisher 12, the fire extinguisher pipe 20, the remote on-off valve 24, the manual on-off valve 26, and the water supply pipe 18.

[0081] The remote on-off valve 24 is an electromagnetic valve or an electric valve, and when the receiver 16 receives a fire signal from the fire detector 14 installed in the protected area 10, it outputs a control signal (open control signal) to the remote on-off valve 24 to open it and supply tap water as an extinguishing agent to the fire extinguishing device 12.

[0082] When the remote on-off valve 24 is opened to supply tap water to the fire extinguishing apparatus 12, the sheet deployment section described later operates to release the hold on the sheet 28, and as shown in Figure 2, one end edge of the sheet 28 is deployed from top to bottom (vertically) so as to block the entrance / exit 11 of the protected area 10. At the same time, tap water is supplied to the extinguishing agent distribution path of the sheet 28 and released into the protected area 10 from multiple release ports 30, thereby suppressing and extinguishing the fire.

[0083] Here, if the up-down direction (height direction) of the deployed sheet 28 is defined as the vertical direction and the direction perpendicular to the up-down direction as the horizontal direction, tap water is discharged as a fire extinguishing agent from a row of discharge ports, for example, 3 vertical by 3 horizontally arranged discharge ports 30, toward the depth direction within the protected compartment 10 to suppress and extinguish the fire. At this time, the tap water is sprayed from the side into the protected compartment 10.

[0084] 3, the higher the position of the outlet 30, which is arranged in three tiers in the vertical direction (up-down direction) of the sheet 28, the farther the outlet 30 reaches, covering almost the entire area on the floor side of the protected area 10 as the outlet distance, as shown in Fig. 3. Furthermore, if furniture such as a table 31 is placed within the protected area 10, the water discharged from the outlets 30 of the unfolded sheet 28 will also reach the underside of the table 31. Note that, if it is desired to discharge water onto the ceiling surface, part of the outlet 30 in the top tier may be oriented upwards so that the ceiling surface is wetted and the spread of the fire is prevented.

[0085] The extinguishing agent (tap water) is released from multiple outlets 30 located in various parts of the unfolded sheet 28 in an overall area-wide manner. Unlike conventional point-type release where a sprinkler head is installed on a ceiling surface, this type of release covers a wide range (spraying range) even with the same amount of release, and the extinguishing agent can reach positions that are hidden from above, such as under tables 31 and desks. As a result, it is possible to suppress and extinguish a fire with a smaller amount of extinguishing agent released.

[0086] (b2. Fire extinguishing equipment in group homes) As shown in FIG. 4, the fire extinguishing equipment of the group home using the fire extinguishing apparatus 12 of this embodiment is configured such that the fire extinguishing apparatus 12 is installed, for example, above the entrance of each room that is to be the protected area 10 (10-1, 10-2, . . . 10-n), and one end of the extinguishing agent piping 20 is connected to the extinguishing agent supply port of the fire extinguishing apparatus 12. The other end of the extinguishing agent pipe 20 is connected to the water pipe 18 of the water facility via a remote opening / closing valve 24 and a manual opening / closing valve 26, which are connected in parallel. Note that the gate valve 25 shown in FIG. 1 is omitted.

[0087] Fire detectors 14 installed in each of the protected compartments 10 (10-1, 10-2, . . . , 10-n) are connected to a receiver 16, which monitors each protected compartment (room) for fires.

[0088] When a fire breaks out in any of the protected compartments 10 (10-1, 10-2, . . . 10-n), the corresponding fire detector 14 is activated and transmits a fire signal to the receiver 16. Based on the fire signal, the receiver 16 outputs a control signal (open control signal) to the remote on-off valve 24 corresponding to the protected compartment where the fire has occurred to open it, supplies an extinguishing agent (tap water) to the fire extinguishing apparatus 12 installed in the protected compartment where the fire has occurred, and, as shown in Figures 2 and 3, unfolds the sheet 28 of the fire extinguishing apparatus 12 and releases the extinguishing agent (tap water) over a surface from multiple discharge ports 30 arranged in various places on the unfolded sheet 28 to suppress and extinguish the fire.

[0089] [c. Fire extinguishing sheet] (c1. Sheet composition) The sheet 28 (28a) of this embodiment shown in Figure 5 is a rectangular sheet whose length and width correspond to the size of the installation location of the protected area, for example an entrance / exit, when deployed, and since it is made of a cloth-like material, it is flexible and can be easily undeployed by rolling it up into a roll.

[0090] An extinguishing agent supply port 32 serving as an inlet for the extinguishing agent is disposed on one end side (upper end side) of the sheet 28, an extinguishing agent flow path 34 shown by a dotted line is provided inside, and a plurality of discharge ports 30 are disposed at various points on the extinguishing agent flow path 34. In this embodiment, the discharge ports 30 are disposed at nine locations in three rows and three columns.

[0091] In addition, the extinguishing agent flow path 34 is formed in a four-stage ladder shape in the vertical direction (the direction in which the extinguishing agent flows downward), with an extinguishing agent supply port 32 provided in the center of the topmost first stage, and discharge ports 30 arranged in, for example, three locations each on the second to fourth stages.

[0092] The extinguishant flow path 34 is formed so as to supply extinguishant from both ends of each outlet row element to the horizontal outlet rows of the outlets 30 arranged in the second to fourth rows (each outlet row arranged in the horizontal direction is regarded as one outlet row element, and the outlet row elements are arranged in three rows from the second to fourth rows to constitute the entire outlet row). This makes it possible to make the discharge pressure of the extinguishant supplied to the multiple outlets 30 in the same row approximately uniform, and to make the discharge pattern (angle distribution) and discharge amount in the same row uniform.

[0093] The shape of the extinguishant flow path 34 for supplying the extinguishant to the multiple discharge ports 30 is not limited to the ladder shape shown in the figure, and may include appropriate shapes such as a tree shape and a tournament shape. In addition, when the discharge pressure of the multiple discharge ports 30 is to be approximately uniform, the thickness (cross-sectional area) of the extinguishant flow path 34 may be made thicker on the extinguishant supply port 32 side and thinner as it moves away from the extinguishant supply port 32. In addition, the number and arrangement of the discharge ports 30 provided corresponding to the extinguishant flow path 34 are arbitrary.

[0094] (c2. Seat manufacturing method 1) The sheet 28 (28a) of this embodiment shown in FIG. 5 is manufactured, for example, by the method shown in FIG. 6. First, a first cover sheet 36 and a second cover sheet 38 of a predetermined size are prepared. The first cover sheet 36 and the second cover sheet 38 are, for example, fabric-like bodies having fireproofing, fire resistance, heat resistance, or flame retardancy, and can withstand high heat of, for example, 1200°C, and may be called fireproof sheets, fireproof curtains, fireproof screens, etc., but are not limited thereto. In addition, the first cover sheet 36 and the second cover sheet 38 each have heat-shielding, flame-shielding, or smoke-shielding properties. It is not prohibited to make only the cover sheet facing the inside of the protected compartment fireproof, fire-resistant, heat-resistant, flame-retardant, heat-shielding, or flame-shielding properties.

[0095] Next, a sheet piping 40 is prepared, which is, for example, a four-stage ladder-shaped sheet piping 40. The sheet piping 40 is made by forming a cloth material such as polyester used for upholstery into a pipe shape and connecting it in a ladder shape (connections are made to be able to flow), and as shown in Fig. 7(A), it can be crushed and deformed freely, becoming flat when crushed, and when extinguishing agent 41 is supplied, it expands as shown in Fig. 7(B), forming an extinguishing agent flow path 34.

[0096] As shown in FIG. 6, the sheet piping 40 is provided with an extinguishing agent supply port 32 and a discharge port 30, and a through hole 56 is formed in the first cover sheet 36 corresponding to the discharge port 30.

[0097] The discharge port 30 has a structure, for example, as shown in Fig. 8. The discharge port 30 is composed of a base 42 and a clamping ring 44. A screw shaft 46 stands on the base 42, and a discharge hole 50 penetrates the screw shaft 46. The clamping ring 44 has a screw hole 48, and is fixed by screwing it onto the screw shaft 46.

[0098] As shown in Fig. 8(A), the base 42 is disposed in the sheet piping 40 and, for example, as shown in Fig. 8(C), is bonded and fixed at the adhesive portion 43, and the screw shaft 46 is taken out to the outside. The screw shaft 46 taken out from the opening provided in the sheet piping 40 is taken out through the through hole 56 (see Fig. 6) of the first cover sheet 36, and the clamping ring 44 is screwed into it, so that the sheet piping 40 is clamped and fixed in a state where it is disposed on the back surface of the first cover sheet 36.

[0099] Next, as shown in FIG. 6, a sheet piping 40 having a discharge port 30 and an extinguishing agent supply port 32 is placed on the back side of the first cover sheet 36, and a second cover sheet 38 is placed on the opposite side of the first cover sheet 36 with the sheet piping 40 in between. The first cover sheet 36 and the second cover sheet 38 are then glued or sewn together using waterproof thread with the sheet piping 40 in between, thereby completing the sheet 28 (28a) shown in FIG. 5.

[0100] Here, the discharge hole 50 provided in the base 42 of the discharge port 30 determines the opening diameter of the discharge port 30, and since the water pressure of the tap water supplied as the extinguishing agent is about 0.02 MPa, the hole diameter is set to, for example, about 3 to 4 millimeters.

[0101] The hole diameter of about 3 to 4 millimeters corresponds to the diameter of one of the multiple water outlet holes formed in a typical shower head that uses tap water. Therefore, a tap water outlet pattern equivalent to one of the holes in a shower head is obtained from the outlet 30, and this outlet pattern is released from the multiple outlets 30 arranged in various places on the sheet 28, resulting in an overall planar release.

[0102] The discharge hole 50 also functions as a nozzle that determines the discharge pattern of the extinguishing agent. For example, the straight discharge hole 50 shown in the figure results in a relatively narrow-angle discharge pattern, and if the outlet opening of the discharge hole 50 is widened into a cone shape, a wide-angle discharge pattern spreading in a cone shape will result, and an appropriate opening shape is selected according to the required discharge pattern. Discharge ports 30 with different opening shapes may be appropriately mixed.

[0103] In this embodiment, the central axis of the discharge hole 50 (the dashed line in the figure) is perpendicular to the sheet 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 sheet surface.

[0104] Furthermore, a coolant discharge port may be provided in the sheet pipe 40 constituting the extinguishing agent flow path as wetting means (cooling means) for wetting and cooling the first cover sheet 36 and the second cover sheet 38 separately from the discharge port 30, or a coolant sheet pipe constituting the coolant flow path may be provided separately from the sheet pipe 40 or branched off from the sheet pipe 40, and a coolant discharge port may be provided in this. This improves the fire resistance, fire resistance, and heat resistance of the first cover sheet 36 and the second cover sheet 38, and enables the use of lower grade sheets, thereby reducing costs.

[0105] (c3. Seat manufacturing method 2) Figure 9 is an explanatory diagram showing another method of manufacturing the sheet 28. For the sheet 28 (28b) in Figure 9, a first cover sheet 36, a first waterproof sheet 52, a second waterproof sheet 54, and a second cover sheet 38 of predetermined sizes are prepared. The first cover sheet 36 and the second cover sheet 38 are the same as those in the manufacturing method of Figure 6, and the first waterproof sheet 52 and the second waterproof sheet 54 are made of a cloth-like material such as polyester used for lining umbrellas, similar to the sheet piping 40 in the manufacturing method of Figure 6.

[0106] In the first waterproof sheet 52, the extinguishing agent supply port 32 is disposed corresponding to the extinguishing agent flow path 34 to be formed, and through holes 56, 58 are formed corresponding to the discharge port 30.

[0107] The first cover sheet 36 and the first waterproof sheet 52 are overlapped with the through holes 56, 58 aligned, and then fixed by attaching the discharge port 30 as shown in Figure 10. The structure of the discharge port 30 is the same as that shown in Figure 8, and is composed of a base 42 with an upright screw shaft 46 that passes through the discharge hole 50, and a clamping ring 44 with a screw hole 48.

[0108] With the first cover sheet 36 and the first waterproof sheet 52 fixed by the discharge port 30, the second waterproof sheet 54 and the second cover sheet 38 are overlapped as shown in Fig. 9, and in this state, as shown in Fig. 11, a seam 60 is formed by sewing with a sewing machine or the like using waterproof thread, to create the extinguishing agent distribution path 34. Furthermore, with the sheets overlapped, the edges of the sheets are sewn together at a seam 61, which integrates them into the sheet 28.

[0109] Figure 12(A) shows the extinguishing agent flow path 34 formed by overlapping the first cover sheet 36, the first waterproof sheet 52, the second waterproof sheet 54 and the second cover sheet 38, with a seam 60 sewn by a sewing machine using waterproof thread, for example. Under normal circumstances, the extinguishing agent flow path 34 is in a collapsed state, and when extinguishing agent 41 is supplied, it expands as shown in Figure 12(B) to allow the extinguishing agent to flow.

[0110] Here, by doubling the stitching 60, the sealing performance of the extinguishing agent flow path 34 is improved, but when tap water is supplied as an extinguishing agent, a small amount of the water may leak from the stitching. However, the tap water leaking from the extinguishing agent flow path 34 wets the sheet 28, thereby improving the fire prevention, fire resistance, heat resistance, heat insulation, flame insulation, and smoke insulation properties against fire.

[0111] In this way, a coolant discharge port may be provided in the extinguishant flow path 34 formed by the stitching portion 60 as a wetting means (cooling means) for wetting and cooling the first cover sheet 36 and the second cover sheet 38 separately from the discharge port 30. The coolant discharge port may be provided by adjusting the stitching portion 60 forming the extinguishant flow path 34 so that the stitching is partially larger, or by sewing with partial skipping of stitching, or by partially increasing the stitching interval and using this gap as the coolant discharge port. Also, a flow path (cooling flow path) in which the coolant discharge port is provided may be provided separately from the extinguishant flow path. Note that the extinguishant doubles as the coolant here, but the extinguishant and the coolant may be different. In this case, a coolant pipe may be provided separately from the extinguishant pipe, and a coolant supply port having a similar configuration may be provided separately from the extinguishant supply port, and connected to the coolant pipe.

[0112] [d. Sheet deployment configuration] (d1. Seat deployment structure) As shown in Figures 13(A) and (B), in the fire extinguisher 12 of this embodiment, one end edge (the upper end edge when unfolded) of the sheet 28 is fixed to the main body 62 by a sheet fixing part 63, and under normal circumstances, the sheet 28 is in an unfolded state wound up in a roll shape and held in a suspended state at multiple points by sheet holding members 64 made of wires or ropes on the underside of the main body 62.

[0113] One end of the sheet holding member 64 is fixed to the main body 62, and the other end is passed under the outer periphery of the rolled-up sheet 28 and detachably held by a sheet holding release part 66 on the opposite side (opposite the fixed side) of the main body 62. The sheet holding release part 66 operates upon receiving a supply of extinguishing agent from the extinguishing agent piping 20, and releases the holding of the sheet holding member 64.

[0114] 13(C)(D), when the sheet holding releasing section 66 releases the holding of one end of the sheet holding member 64, the other end edge (the lower end edge when unfolded) of the sheet 28 falls by its own weight and unfolds from above downward (vertically) with one end edge (upper end edge) of the sheet 28 fixed to the main body 62. Note that a predetermined weight member may be provided on the lower end edge side of the sheet 28, which can assist in preventing the lower end edge of the sheet 28 from falling and in stabilizing the sheet 28 after unfolding.

[0115] (d2. Configuration of the seat deployment section) 14, the sheet retention release section 66 of this embodiment is provided with an actuator 68 that is operated by receiving a supply of extinguishing agent within the main body 62. The actuator 68 has a piston 72 slidably mounted in a cylinder 70 via a return spring 76, a cylinder chamber 70a is formed on one side of the piston 72, and the extinguishing agent piping 20 is branched and connected to an extinguishing agent supply port 78. An automatic drain valve 73 is provided for the cylinder chamber 70a. The automatic drain valve 73 closes when the extinguishing agent is supplied at a pressure exceeding a predetermined pressure, and opens when the pressure drops below the predetermined pressure.

[0116] The piston 72 is provided with a rod 74 coaxially therewith. An opening 82 is provided in the front part of the main body 62, so that a part of the rod 74 can be seen and an operating stick 80 provided on the rod 74 is exposed so as to be operable.

[0117] When the sheet holding member 64 is held on the rod 74, the rod 74 is moved to the left using the operating stick 80, and a retaining ring 64a, which is made of, for example, a wire and has a loop-shaped end, is passed through the rod 74 to hold the sheet 28 wound in a roll.

[0118] In the event of a fire, tap water is supplied as an extinguishing agent to the cylinder chamber 70a via the extinguishing agent piping 20, causing the piston 72 to stroke leftward against the return spring 76. This causes the rod 74 to come out of the retaining ring 64a, releasing the sheet retaining member 64, and the sheet 28 falls under its own weight and deploys from above to below.

[0119] The sheet retention release section 66 is provided with an actuator 68 that releases the retention of the sheet retention member 64 upon receiving a supply of extinguishing agent, so that even during a power outage, the sheet 28, which is in an undeployed state, can be deployed in conjunction with the supply of extinguishing agent to release the extinguishing agent.

[0120] The seat holding release section 66 is not limited to the above, and may release the seat holding member 64 and unfold the seat 28 by driving an electromagnetic solenoid or the like in response to a control signal from the receiver 16 .

[0121] Other suitable structures may be applied as the sheet deployment structure of the fire extinguisher 12, and may include a structure in which the sheet 28 is wound around a rotating shaft and the latch of the rotating shaft is released to deploy the sheet 28, or a structure in which the sheet 28 is unwound and wound up by motor drive. Also, the sheet 28 may be held in a bellows-like folded state and released to deploy.

[0122] 5 and 11, the extinguishing agent flow path 34 of the sheet 28 may be arranged in a rectangular shape surrounding the periphery of the ladder shape, for example, to function as a weight that assists the deployment of the sheet 28 when extinguishing water is supplied as an extinguishing agent and serves as an auxiliary means for stabilizing the deployed state. By lengthening the extinguishing agent flow path up to the discharge port 30, it can function as a buffer area that suppresses the pressure rise (or the rate of rise) when the supply of extinguishing agent from a fire extinguisher, which will be explained later, to a predetermined level (to the extent that the extinguishing agent flow path 34 and the discharge port 30 are not damaged).

[0123] [e. Fire extinguishing equipment and facilities using fire extinguishers] As shown in FIG. 15, this embodiment uses a fire extinguisher as an example of the extinguishing agent supplying device, and is characterized in that a predetermined extinguishing agent, such as a powder extinguishing agent or a reinforced liquid extinguishing agent, is supplied and discharged from a fire extinguisher 84 to a fire extinguishing device 12 installed at the boundary of a room that serves as a protective compartment 10, for example, above an entrance / exit.

[0124] The fire extinguisher 84 has a main container filled with extinguishing agent under pressure. When the safety pin 90 is removed and the lever 92 is pressed down, the extinguisher 84 opens and the extinguishing agent is released from the hose 86.

[0125] One end of the extinguishant pipe 20 is connected to the extinguishant supply port 32 of the sheet 28 (28c) provided on the fire extinguisher 12, and the other end of the extinguishant pipe 20 is connected to a fire extinguisher nozzle 94a at the tip of a hose 86 of a fire extinguisher 84 via a fire extinguisher connector 94 that functions as a connector. The fire extinguisher connector 94 is composed of the fire extinguisher nozzle 94a and a fire extinguisher connection port 94b, and uses a known connector similar to that used to detachably connect a hose to a water faucet with a single touch.

[0126] Here, in this embodiment, the fire extinguisher nozzle 94a is formed by removing the nozzle already attached to the hose tip of the fire extinguisher 84 and attaching a separately prepared fire extinguisher nozzle 94a in advance, but this is not limited to this.

[0127] FIG. 16 shows an example of a fire extinguisher connection part 94, which is equipped with a fire extinguisher nozzle 94a and a fire extinguisher connection port 94b. A separately prepared fire extinguisher nozzle 94a is provided at the tip of a hose 86 of the fire extinguisher 84, and a fire extinguisher connection port 94b is provided at the other end of the extinguishant piping 20, making the hose 86 of the fire extinguisher 84 detachable from the extinguishant piping 20.

[0128] The fire extinguisher nozzle 94a has a nipple 95a with an O-ring attached at its tip, and is connected and fixed by inserting the nipple 95a into the opening of the fire extinguisher connection port 94b. The fire extinguisher connection port 94b has a slider 95b, and the connected fire extinguisher nozzle 94a can be removed by sliding the slider 95b in the direction of the arrow in the figure.

[0129] FIG. 17 shows an embodiment of a sheet 28 (28c) used to release an extinguishant from a fire extinguisher 84. The sheet 28 (28c) has a buffer area 96 adjacent to the extinguishant supply port 32, and an extinguishant distribution path 34 is provided through the buffer area 96 with release ports 30 arranged at various locations.

[0130] When the fire extinguisher 84 is opened to supply extinguishing agent to the sheet 28 (28c), the accumulated pressure of the fire extinguisher 84 is high, for example, 0.7 MPa to 0.98 MPa, and if high-pressure extinguishing agent is applied to the extinguishant flow path 34 and discharge outlet 30 of the sheet 28 (28c) when the fire extinguisher 84 is opened, there is a possibility that they will be damaged.

[0131] Therefore, a buffer area 96 is provided as a pressure buffer means on the inlet side of the extinguishant flow path 34, and the extinguishant from the fire extinguisher 84 is temporarily retained in the initial stage after the start of the extinguishant supply, thereby keeping the increase (or rate of increase) of the extinguishant supply pressure below a predetermined level, thereby preventing damage to the extinguishant flow path 34 and the discharge port 30. The rest of the configuration is the same as the sheet 28 (28a) in Fig. 5 or the sheet 28 (28b) in Fig. 11.

[0132] In addition, instead of or in addition to the buffer area 96 (pressure buffering means), a pressure buffering device (second pressure buffering means) such as an orifice or tank may be provided in the extinguisher connection part 94, the extinguishant pipe 20, the extinguishant supply port 32, etc., to adjust the rise (or rise rate) of the extinguishant supply pressure from the fire extinguisher 84 to a predetermined level (to the extent that the extinguishant flow path 34 and the discharge port 30 are not damaged). In addition, the buffer area 96 may be arranged below the sheet 28 (28c) so that it functions as a weight (auxiliary means) when the sheet 28 (28c) is deployed. Such pressure buffering means and second pressure buffering means may be provided as necessary in the embodiments described in Figs. 1 to 14.

[0133] In the protected area 10 shown in Fig. 15, a fire detector 14 is installed as a fire detection facility and connected to a receiver 16. In this embodiment, a fire alarm light 16a is installed near the location where a fire extinguisher 84 is installed, and when the receiver 16 receives a fire signal from the fire detector 14 and outputs a fire alarm, the fire alarm light 16a is turned on or blinks in response to a control signal from the receiver 16 linked to the fire alarm, thereby indicating the location of a fire extinguisher 84 that requires a fire extinguishing operation (specifically, a tap opening operation) or is available for extinguishing. Here, the fire extinguishing facility of this embodiment is composed of a fire extinguishing device 12, an extinguishing agent pipe 20, a fire extinguisher 84, and a fire extinguisher connector 94.

[0134] In the fire extinguisher 12 of this embodiment, when a user performs an opening operation by removing the safety pin 90 of the fire extinguisher 84 placed at a predetermined position outside the room that becomes the protected compartment 10 and gripping the lever 92, a fire extinguishing agent is supplied to the sheet 28 (28c) installed at the boundary of the room that becomes the protected compartment 10, for example, above the entrance / exit, and the sheet 28 (28c) is deployed and the fire extinguishing agent is released over a surface from multiple release ports 30 arranged in various places on the sheet 28 (28c), making it possible to suppress and extinguish the fire effectively in a short period of time.

[0135] Furthermore, even if a user is unfamiliar with handling the fire extinguisher 84, since the fire extinguisher 84 is installed, for example, outside the room that serves as the protected area 10 and is away from the location where the fire started, the user can operate it calmly without panicking, and can quickly and reliably open the fire extinguisher 84.

[0136] Furthermore, the discharge of extinguishing agent by the fire extinguisher 84 is short, for example, for about 10 seconds, and if the fire is not extinguished even after the fire extinguisher 84 has been used up, the discharge of extinguishant can be continued by removing the fire extinguisher nozzle 94a from the fire extinguisher connection port 94b of the fire extinguisher connection part 94 and replacing it with an unused fire extinguisher 84 (a separately prepared fire extinguisher nozzle 94a is attached to the hose 86 in advance) that has been prepared separately, 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 can be connected, or by providing fire extinguisher connection parts at a plurality of places on the extinguisher piping.

[0137] In addition, in the event of a fire occurring in a location other than the protected area 10 (a location where the fire extinguishing apparatus 12 of this embodiment is not installed), the fire extinguisher 84 can be removed from the extinguishing agent piping 20 and carried to the location of the fire for use, eliminating the need to increase the number of fire extinguishers installed and reducing the increase in maintenance costs.

[0138] [f. Fire extinguishing equipment combining fire extinguishers and water piping] As shown in FIG. 18, this embodiment is characterized in that the extinguishing agent supply source for the fire extinguishing apparatus 12 installed at the boundary of a room that serves as a protected area 10, for example, above an entrance, is a combination of a fire extinguisher 84 that supplies, as an extinguishing agent, for example, a powder fire extinguishing agent or a reinforced liquid fire extinguishing agent, and a water supply pipe 18 that supplies tap water as an extinguishing agent.

[0139] One end of the extinguishing agent piping 10 is connected to the extinguishing agent supply port 32 of the sheet 28 (28c), and the other end is connected to the water piping 18 via a remote on-off valve 24 and a manual on-off valve 26 connected in parallel, which are piping opening and closing means for opening and closing the piping flow path by remote control or manually.

[0140] In addition, a fire extinguisher 84 is connected to a pipe branching off from between one end of the extinguishant piping 20 and the remote on-off valve 24 and the manual on-off valve 26 (point A in the figure) via a check valve 98 serving as backflow prevention means for preventing backflow of tap water from the extinguishant piping 20 side to the fire extinguisher 84 side, and further, a fire extinguisher connecting part 94 serving as connecting means for detachably connecting the fire extinguisher 84 to the fire extinguisher piping 20 is provided. The fire extinguisher connecting part 94 is composed of a fire extinguisher nozzle 94a and a fire extinguisher connection port 94b, and has a connecting joint structure similar to that shown in FIG. 16, for example.

[0141] A fire detector 14 is installed in the protected area 10 as a fire detection system and is connected to the receiver 16. An alarm indicator light 16a is installed near the location where the fire extinguisher 84 is installed and connected to the receiver 16. When the receiver 16 receives a fire signal from the fire detector 14 and outputs a fire alarm, the fire alarm light 16a receives a control signal from the receiver 16 linked to the fire detector 14 and lights up or flashes, and is a display means for displaying the location of the fire extinguisher 84 that requires or can be extinguished. In addition, a control line for the remote opening and closing valve 24 is connected to the receiver 16. Here, the fire extinguishing system of this embodiment is composed of the fire extinguishing device 12, the extinguishing agent piping 20, the fire extinguisher 84, the fire extinguisher connection part 94, the check valve 98, the remote opening and closing valve 24, the manual opening and closing valve 26, and the water supply piping 18.

[0142] The receiver 16 can be set to, for example, an automatic extinguishing mode and a manual extinguishing mode. The automatic extinguishing mode is set, for example, during a time period such as nighttime, and extinguishing agent is discharged by opening the remote on-off valve 24 based on a control signal (open control signal) from the receiver 16 linked to fire detection by the fire detector 14 (fire alarm of the receiver). The manual extinguishing mode is set, for example, during the daytime, and extinguishing agent is discharged by opening the fire extinguisher 84 or the manual on-off valve 26. Note that in addition to switching between the manual extinguishing mode and the automatic extinguishing mode depending on whether people are present or absent, or a combination of these modes may be used.

[0143] If the receiver 16 is set to the manual fire extinguishing mode, when a fire breaks out in the protected area 10, the receiver 16 receives a fire signal from the fire detector 14 and outputs a fire alarm, and also turns on or flashes the alarm indicator light 16a installed corresponding to the protected area 10 where the fire has broken out.

[0144] When a fire occurs, relevant personnel go to the protected area 10 where the fire has occurred, and upon confirming the fire, remove the safety pin 90 of the fire extinguisher 84 and push down the lever 92 to open it, and supply the extinguishing agent from the fire extinguisher 84 to the fire extinguishing device 12, which deploys the sheet 28 (28c) and releases powder fire extinguishant or the like over a surface from multiple discharge ports 30 located in various places on the sheet 28 (28c), thereby suppressing and extinguishing the fire.

[0145] If it is not possible to confirm that the fire has been extinguished even after the extinguishing agent from the fire extinguisher 84 has been discharged, the manual on-off valve 26 is opened to supply tap water to the fire extinguishing device 12, and the tap water is discharged from the multiple discharge ports 30 arranged in various places on the deployed sheet 28 (28c) 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 84, and since there is no time constraint on the discharge of tap water, it is possible to reliably extinguish the fire.

[0146] On the other hand, if the automatic fire extinguishing mode is set in the receiver 16, the receiver 16 receives a fire signal from the fire detector 14 and sends an open control signal to the remote on-off valve 24 to open it, supply tap water to the fire extinguishing device 12, deploy the sheet 28 (28c), and release tap water from multiple outlets 30 located in various places on the sheet 28 (28c) to suppress and extinguish the fire.

[0147] 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 abating, they can perform a predetermined operation, for example, closing the remote opening / closing valve 24 on the receiver 16, for example, by canceling the automatic extinguishing mode and switching to the manual extinguishing mode, and then the safety pin 90 of the fire extinguisher 84 can be removed and the lever 92 can be pushed down to open the fire extinguisher 84, supplying extinguishing agent from the fire extinguisher 84 to the fire extinguishing device 12, and discharging the extinguishing agent from multiple discharge ports 30 located in various places on the deployed sheet 28 (28c), thereby suppressing and extinguishing the fire.

[0148] In this way, after the extinguishing agent has been discharged from the fire extinguisher 84, the manual on-off valve 26 can be opened again to switch back to discharging tap water.

[0149] [g.Fire extinguishing equipment with fixed sheets] As shown in FIG. 19, this embodiment is characterized in that a sheet 28 of the fire extinguisher 12 is fixedly installed in a protected compartment 10 in an unfolded state.

[0150] The fire extinguisher 12 of this embodiment is composed of an attachment part 12a and a sheet 28, and one end of the sheet 28 is fixed to the attachment part 12a. For example, the fire extinguisher 12 is configured such that the attachment part 12a is fixed to the upper part of a predetermined wall surface of a room that will become the protected compartment 10, the sheet 28 with one end fixed to the attachment part 12a is lowered along the wall surface, and the sheet 28 is fixed to the wall surface with rivets or the like so as not to swing. The rest of the configuration is the same as the embodiment of FIG. 1.

[0151] According to this embodiment, the seat deployment structure shown in FIG. 13 is not necessary, so the configuration is simplified and costs can be reduced.

[0152] Fig. 20 shows another embodiment of the fire extinguisher 12 in which a sheet is fixedly installed, and the fire extinguisher 12 of this embodiment is composed of an attachment part 12a and a sheet 28 (line sheet 28d), and the sheet 28 (28d) has a plurality of discharge ports 30 arranged in a single straight line. The sheet 28 (28d) can be manufactured in the same manner as shown in Fig. 6 or Fig. 9. The sheet 28 (28d) is connected to the fire extinguishing agent pipe 20, and when a fire occurs, the remote opening / closing valve 24 is controlled to open by the receiver 16 or the manual opening / closing valve 26 is opened to supply tap water as a fire extinguishing agent, and the fire extinguishing agent is discharged from the discharge port 30 provided in the sheet 28 (28d) to suppress and extinguish the fire.

[0153] In the present embodiment, the sheet 28 (28d) extinguishes and suppresses a fire by linearly discharging the extinguishing agent by constituting the entire discharge port row only with discharge port row elements in which the discharge ports 30 serving as discharge points are arranged in a single horizontal straight line. The sheet 28 (28d) may be arranged in the up-down direction (vertical direction) or in an oblique direction.

[0154] 19 and 20 exemplify tap water as an extinguishing agent, the fire extinguisher 84 shown in Fig. 15 may be used as the extinguishing agent supply source, or the fire extinguisher 84 may be combined with tap water as shown in Fig. 18. In this case, a pressure buffer device (second pressure buffer means) for regulating the rise in extinguishant supply pressure from the fire extinguisher 48 to a predetermined level may be provided in the fire extinguisher connection part 94 between the fire extinguisher 48 and the line sheet 28 (28d), the extinguishant piping 20, the extinguishant supply port 32, or the like.

[0155] Moreover, a surface discharge of the extinguishing agent may be obtained by using a plurality of sheets 28 (28d). For example, by arranging a plurality of sheets 28 (28d) in parallel on the same surface, the extinguishing agent can be discharged surface-wise as a whole.

[0156] [h. Basic Concepts of Warehouse Fire Extinguishing Equipment] The basic concept of the embodiment of the fire extinguishing system for a warehouse using the fire extinguishing appliances shown in Figs. 5 to 14 will be described.

[0157] The warehouse in which the fire extinguishing equipment is installed includes a storage shelf and a transport means. The term "storage shelf" refers to a shelf on which a plurality of storage sections are arranged, and is a concept that includes, for example, a rack shelf on which a plurality of racks are arranged vertically and horizontally.

[0158] Further, the term "conveying means" refers to a means for transporting the target item to and from the storage section (carrying it in or carrying it out of the storage section), and is a concept that includes, for example, a so-called stacker crane and the like.

[0159] The fire extinguishing equipment is arranged to partition a predetermined target section including the location of the fire in the storage shelf and release the extinguishing agent into the target section. Here, the "target section" in the following embodiment of the warehouse fire extinguishing system is an area section to be extinguished, that is, for example, a predetermined section in the storage shelf where the fire has occurred. The storage shelves are classified into storage shelves without partition structures in the vertical direction (height direction) and storage shelves with partition structures depending on whether or not they have shelves. Here, in the case of a storage shelf with a partition structure, the target section is the storage section (internal space of the storage section) itself, for example, a specified rack (internal space of the rack), while in the case of a storage shelf without a partition structure, the target section is a storage section row (internal space of the storage row) in which multiple storage sections are arranged vertically, for example, a specified rack row (internal space of the rack row).

[0160] Furthermore, the rack or row of racks is configured with the closed upper and lower structural surfaces and the open opening surfaces of the other surrounding areas (surroundings excluding the top and bottom) as boundaries, and fire extinguishing equipment is provided corresponding to the opening surfaces. In such an embodiment of a warehouse fire extinguishing system, if the target section is, for example, a rack or row of racks, "partitioning the target section" refers to the concept of unfolding the fire extinguishing equipment sheet to cover at least the opening surfaces of the rack or row of racks, thereby sealing all of the surfaces that form the boundaries of the rack or row of racks (for example, all six boundary surfaces in the case of a rectangular parallelepiped) with almost no gaps, together with the structural surfaces other than the opening surfaces (however, the interior does not have to be completely sealed).

[0161] Below, we will provide a detailed explanation of the case of an automated warehouse in which the "storage shelf" is a "rack shelf," the "storage section" is a "rack," the "storage section row" is a "rack row" consisting of multiple racks lined up vertically, and the "transport means" is a "stacker crane."

[0162] [i. Specific details of the warehouse fire extinguishing equipment] (i1. Overview of the automated warehouse) As shown in Fig. 21, a rack shelf 110 is installed in the automated warehouse 100, and this embodiment takes as an example a rack shelf 110 that does not have a partition structure with shelf boards. A plurality of racks 118 are arranged vertically and horizontally on the rack shelf 110, and a stacker crane 120 is used to carry an item into any of the racks 118 for storage, and also to carry out the stored item. Here, for the rack shelf 110, as shown in the figure, the up-down direction with the side where the top plate 114 is arranged is the upside is referred to as the vertical direction or height direction, the longitudinal direction of the top plate 114 perpendicular to the up-down direction is referred to as the left-right direction or horizontal direction, and the short side direction is referred to as the front-rear direction or depth direction.

[0163] Rack shelf 110 has a pair of support posts 112 that stand at a specified interval in the depth direction of the floor surface, and a top plate 114 is placed on the upper end of each support post 112. Rack shelf 110 has four adjacent support posts 112 as one unit, and a rack row is formed in which racks 118 are arranged in four tiers in the vertical direction.

[0164] 21 and 22, a pair of rack rails 116 are arranged in parallel in the depth direction and spaced apart vertically at a predetermined interval to form four tiers of racks 118. Items are loaded onto a pallet (cargo platform) 130 by a stacker crane 120 and carried into and out of the rack 118.

[0165] The rows of racks formed in this manner have no shelf boards dividing them vertically, and therefore form a rack space that penetrates vertically when no articles are stored.

[0166] The stacker crane 120 has a gate-shaped crane frame 124 mounted on a traveling cart 122 that travels left and right along a traveling rail 132, and the upper side of the crane frame 124 is guided by a ceiling rail 134. A lifting platform 126 is provided on the crane frame 124, and two sets of fork transfer devices 128 are mounted on it, which allows the lifting platform 126 to be moved up and down to transport articles on a pallet 130 to any of the racks 118.

[0167] An article is carried into the rack 118 as follows. First, the stacker crane 120 moves along the traveling rails 132 to the traveling platform 136 side and stops. The traveling platform 136 is then positioned at the carry-in section 138 along the traveling rails 135, and articles are loaded onto the pallet 130 from the carry-in section 138. Next, the pallet 130 loaded with articles is transferred to the fork transfer device 128 provided on the lifting platform 126 by the fork device 141 of the traveling platform 136. Finally, the stacker crane 120 moves left and right along the traveling rails 132, and the lifting platform 126 is further moved up and down to carry the article into the desired rack 118.

[0168] Furthermore, the removal of items from the rack 118 is generally performed in the reverse order to the loading operation, and the items on the pallet 130 transferred to the traveling platform 136 by the stacker crane 120 are removed from the unloading section 140 to the outside of the warehouse.

[0169] (i2. Fire extinguishing equipment for rack rows) Next, a fire extinguishing system in which an arbitrary row of racks on the rack shelf 110 is set as a target section will be described in detail.

[0170] The upper end of the rack row is closed by a top plate 114 forming a structural surface, and the lower end is closed by the floor surface of the warehouse forming the structural surface, and the remaining four sides are opening surfaces. The fire extinguishing appliances 12 are installed corresponding to the opening surfaces around the rack row. Specifically, as shown in FIG. 22, four fire extinguishing appliances 12 are installed on the frame sides of the upper ends of four pillars 112 corresponding to the rack row, for example, to form a rectangular frame. Here, the fire extinguishing appliances 12 corresponding to the left and right opening surfaces of the rack row are installed on the upper ends of the pillars 112 so that both ends in the longitudinal direction are approximately in contact with the front and rear pillars 112 facing each other, and in this embodiment, two units are arranged side by side for each pair of front and rear pillars 112 to correspond to the adjacent racks 118. It is to be noted that these may be shared by one unit, and in this case, for example, the sheet 28 of the fire extinguishing appliance 12 may be provided with an independent extinguishing agent flow path 34 and a discharge port 30 on each side.

[0171] As shown in Fig. 23, each of the fire extinguishing appliances 12 installed in this manner is connected to an extinguishing agent pipe 20 from a fire pump facility (not shown) for each row of racks via a remote opening and closing valve 24. Also, each of the racks 118 is provided with a fire detector (not shown) serving as a fire detection means.

[0172] When a fire breaks out in a rack 118 or a row of racks, the operation is as follows: As shown in Fig. 24, if a fire breaks out in the rack row on the side of the rack shelf 110 closest to the carry-in section 138 (see Fig. 21), for example, the four fire extinguishing devices 12 arranged at the upper end of the rack row receive a supply of extinguishing agent, for example, deploy the sheet 28, partition off and close the opening of the rack row where the fire has broken out, and then, as shown in Fig. 25, release the extinguishing agent from the discharge port 30, indicated roughly by a triangle, arranged on the inner sheet surface of the sheet 28 (the sheet surface on the side facing the inside of the rack row).

[0173] For this reason, the front, rear, left and right openings of the rack row including the location of the fire are partitioned by the sheet 28, and extinguishing agent is discharged into the rack row where the fire has broken out from the discharge ports 30 provided in various places on the sheet 28, thereby reliably suppressing and extinguishing the fire. Also, by partitioning the opening of the rack row including the location of the fire, the outside of the partitioned rack row is insulated from flames, smoke and heat, preventing the spread of fire and smoke, and further suppressing the dissipation and release of extinguishing agent to the outside, thereby reducing, for example, water damage to items stored in adjacent rack rows.

[0174] (i3. Fire extinguishing equipment for warehouses with racks as target areas) Next, a detailed description will be given of a fire extinguishing system for a warehouse in which an arbitrary rack 118 of the rack shelf 110 is set as a target section.

[0175] As shown in Fig. 26, the automated warehouse 100 according to this embodiment is exemplified by a rack shelf 110 having a partition structure using shelf boards. This rack shelf 110 has, for example, four shelf boards 150 arranged at predetermined intervals in the vertical direction in each rack row of the rack shelf in Fig. 21, forming a four-tiered rack 118.

[0176] Therefore, the top rack 118 is closed at the top by a top plate 114 and at the bottom by a shelf plate 150, and the second to fourth racks 118 from the top are closed at the top and bottom by the shelf plate 150. Each rack has four open sides, and four fire extinguishing appliances 12 are installed on the frame sides at the upper end of the open sides, i.e., on the upper side of each rack, in the same manner as in FIG. 21, so as to form, for example, a rectangular frame. Each rack 118 is also equipped with a fire detector (not shown). The four fire extinguishing appliances 12 arranged on each rack 118 are connected to extinguishing agent piping via a remote opening and closing valve (not shown) in the same manner as in FIG. 23.

[0177] The operation when a fire breaks out in the rack 118 is as follows. As shown in Figures 26 and 27, if a fire breaks out in the rack 118 that is the second tier from the bottom on the side closest to the carry-in section 138 (see Figure 21), the four fire extinguishing devices 12 arranged on the upper part of this rack 118 will, for example, receive a supply of extinguishing agent, deploy sheets 28, partition and close the openings around the rack 118, and release the extinguishing agent into the partitioned rack 118 from a plurality of discharge ports 30, which are diagrammatically shown by triangles.

[0178] For this reason, the front, rear, left and right openings of the rack 118 where the fire has started are partitioned, and the fire is reliably suppressed and extinguished by discharging extinguishing agent into the rack 118 where the fire has started from the discharge port 30 of the deployed sheet 28. Also, by partitioning the opening of the rack 118 where the fire has started, the outside of the partitioned rack 118 is insulated from flames, smoke and heat, preventing the spread of fire and smoke, and further suppressing the dissipation and release of the extinguishing agent to the outside, thereby reducing water damage to items stored in adjacent racks or rows of racks, for example.

[0179] In addition, if a fire breaks out in any rack 118, the fire extinguishing device 12 may be activated to deploy the sheet 28 and spray extinguishing agent on some or all of the other racks 118 in the row of racks that includes the rack 118 in question.

[0180] [j. Modifications of the present invention] A modified example of the present invention will now be described in detail.

[0181] (Sheet outlet placement) In the above embodiment, a plurality of discharge ports 30 are arranged at various locations on one side of the sheet 28, but the present invention is not limited to this, and a plurality of discharge ports 30 may be arranged at various locations on both sides of the sheet 28. The sheet 28 having a plurality of discharge ports 30 arranged at various locations on both sides is used when the fire extinguisher 12 is installed on the ceiling or the like in the center of the room that serves as the protected section 10, and when a fire breaks out, the sheet 28 is deployed from above to below, and the extinguishing agent is surface-discharged to both sides from the plurality of discharge ports 30 on each side of the sheet to extinguish and suppress the fire.

[0182] (Protective Area) The above embodiment takes a room in a group home for elderly people as an example of a protected area, but in the case of a room in an ordinary house or an apartment building, for example, a wireless-linked residential fire alarm may be used instead of the fire detector 14 and receiver 16, and the remote opening / closing valve 24 may be connected to a wireless-linked adapter that receives a fire-linked signal from the residential fire alarm and outputs a contact signal, so that when a fire occurs, the remote opening / closing valve 24 is driven to open by the contact signal to release extinguishing agent over a surface from multiple release ports 30 arranged in various places on the sheet 28.

[0183] Furthermore, the fire extinguisher of the present invention can be applied to, for example, factories, schools, government offices, and other appropriate facilities. Of course, the protected area is not limited to a room, and may be any appropriate area.

[0184] (Fire extinguishing agent distribution route) In the above embodiment, the extinguishing agent flow path 34 is formed by sheet piping or by sewing with a sewing machine or by adhesion using waterproof thread, but the present invention is not limited to this. For example, the extinguishing agent flow path may be formed by using a tube made of resin or the like.

[0185] (Sheet) Furthermore, the shape of the sheet 28 is not limited to that in the embodiment, and may be any suitable shape other than rectangular, such as circular, elliptical, polygonal, etc. Furthermore, the above embodiment has been described as an example in which one sheet 28 is installed in one protected area, but the number of sheets 28 installed in one protected area is arbitrary.

[0186] Any number of extinguishing agent supply ports and pressure buffer areas may be provided per sheet. In this case, a backflow prevention structure (such as a check valve) may be provided for the extinguishing agent supply port to prevent backflow, so as to prevent the extinguishing agent from leaking out from an extinguishing agent supply port that is not connected to an extinguishing agent supply device.

[0187] (Water piping) The water pipe in the above embodiment may include, for example, a water hose. Also, for example, a connecting portion (second connecting means) may be provided that detachably connects the water hose and the extinguishing agent pipe.

[0188] In the above embodiment, the remote on-off valve 24 and the manual on-off valve 26 are provided as the piping opening / closing means, and these are connected in parallel, but only one of them may be provided. That is, it may be opened and closed only by remote control, or it may be opened and closed only manually, although it is not possible to set the automatic mode as in the embodiment of Fig. 28. Of course, connection methods other than parallel connection are not precluded.

[0189] (Automated warehouse) In the above embodiment of the fire extinguishing system for a warehouse, an automated warehouse in which goods are automatically transported to and managed on a rack shelf by a stacker crane is taken as an example, but the present invention is not limited to this, and the type of warehouse to which the system is applied is arbitrary, and the system can also be applied to a so-called manual warehouse in which goods are carried in and out of the rack shelf by operating a forklift. Furthermore, the fire extinguishing system of this embodiment is not limited to warehouses, and can be applied to any appropriate facility in which goods are stored using storage shelves such as rack shelves.

[0190] (Fire extinguishing equipment for automated warehouses) In the above embodiment, four fire extinguishing devices 12 are arranged corresponding to the front, rear, left and right opening surfaces of the rack 118 or the row of racks of the rack shelf 110 as the target section, but the present invention is not limited to this, and fire extinguishing devices may be arranged corresponding to at least one of the front, rear, left and right opening surfaces. In this case, the opening surface on which the fire extinguishing device 12 is not arranged may be left as it is, but for example, the fire extinguishing device 12 equipped with a sheet structured not to discharge extinguishing agent may be arranged so that the sheet is deployed when a fire occurs to close the opening surface without discharging water extinguishing agent. Here, the "fire extinguishing device 12 equipped with a sheet structured not to discharge water extinguishing agent" may be composed of only a cloth-like body obtained by removing the extinguishing agent supply port 32, the extinguishing agent flow path 34 and the discharge port 30 from the sheet 28 (28a, 28b) shown in Figs. 5 to 14.
