Japanese Unexamined Patent Publication No. 2012-152261 Japanese Unexamined Patent Publication No. 2012-179330 Japanese Unexamined Patent Publication No. 9-221201 Japanese Unexamined Patent Publication No. 2012-11620 Japanese Unexamined Patent Publication No. 2011-121771

However, when a fire extinguisher is installed, many people do not know where to install the fire extinguisher when a fire breaks out, and many people are unfamiliar with using a fire extinguisher, making it difficult to quickly and reliably extinguish a fire when a fire breaks out. In some cases. In addition, during fire extinguishing work, there is a risk that it will not be possible to allocate personnel to evacuate vulnerable people early and safely, so if you try to prioritize evacuation guidance, you may not be able to use the fire extinguisher effectively and reliably. is there.

In addition, sprinkler fire extinguishing equipment using tap water operates when the temperature rise due to hot air flow satisfies the operating conditions, and it does not operate unless the scale of the fire becomes large to some extent, so it is not always possible to start extinguishing the fire early. There is a problem that cannot be said. In addition, the sprinkler head locally discharges fire extinguishing water with the installation location as the discharge point, and when the release amount per unit time is restricted like tap water, secure a sufficient release range and release amount. It is difficult to control the fire sufficiently and it may not be possible to extinguish the fire.

Further, in the conventional fire extinguishing system of an automated warehouse, for example, a nozzle is transported to a place where a fire occurs on a rack shelf by a stacker crane to discharge a fire extinguishing agent. May expand and initial fire extinguishing may be too late.

Further, when the fire extinguishing agent is discharged from the nozzle to the place where the fire occurs on the rack shelf, there is a problem that the articles scattered around and stored are wetted, and the damage caused by water damage becomes large.

An object of the present invention is to provide a fire extinguishing device and a fire extinguishing system which are easy to install and efficiently suppress and extinguish a fire with a small amount of emission.

A means of transporting goods to and from the storage unit,
With
The fire extinguisher is characterized in that it is provided so as to partition a predetermined target section including the place where the fire occurs on the storage shelf and discharge the fire extinguishing agent into the target section.

(Target section)
The storage shelves have multiple storage units,
A predetermined target section of the storage shelf is a storage section (rack) or a storage section row (rack row).
The fire extinguisher is provided corresponding to the storage unit or the storage unit row, and when a fire breaks out in the storage unit or the storage unit row, the storage unit or the storage unit row is partitioned to release the fire extinguishing agent.

When a fire is detected by the fire detecting means, a fire extinguishing agent is supplied to the sheet deploying means of the fire extinguisher corresponding to the target section in which the fire is detected, and the undeployed state of the sheet is released and deployed.

(Basic effect of fire extinguishing equipment)
In the fire extinguisher of the present invention, a plurality of outlets are arranged at various locations located on one side of a sheet arranged in a room or the like serving as a protective compartment, for example, facing the inside of the protected compartment, and a plurality of outlets are provided in the event of a fire. By releasing the fire extinguishing agent from the surface, a wider release range can be secured compared to the point release of the conventional sprinkler bed whose release point is the installation location, and the number of places that cause watering obstacles is reduced. The amount of fire extinguishing agent released enables fire suppression and extinguishing.

Here, "surface emission" means that a plurality of emission ports (emission points) are arranged at various locations on the sheet surface, so that the fire extinguishing agent is surface-discharged from the plurality of locations, that is, various locations on the sheet surface. It means that the fire extinguishing agent is discharged from a wide range of the sheet surface by discharging the fire extinguishing agent from the discharge port arranged in. Further, "point release" means that the fire extinguishing agent is released from one point by having a discharge port (release point) at one place (installation place). Further, the linear discharge of the fire extinguishing agent from a plurality of discharge ports arranged in a straight line is called "line discharge".

In addition, the sheet has a size corresponding to the size of an opening such as a door, a wall surface, or a ceiling surface of a protective section. For example, if the amount of discharge from each of the discharge ports is reduced, the sheet is scattered as a whole from, for example, a sprinkler head. It is possible to release the fire extinguishing agent to every corner of the target space with a small amount of fire extinguishing agent compared to the amount of water, and it is possible to suppress and extinguish a fire in a predetermined range efficiently and in a short time. , The influence on the outside is small, and the disaster prevention device can be made lightweight and simple.

In addition, when the sheet is deployed from above to below (deployed along the side surface of the protected area) and used as an outlet that discharges the fire extinguishing agent mainly in the direction perpendicular to the sheet surface, the fire extinguishing agent is spread sideways ( The fire extinguishing agent reaches the protected area (for example, from the side of the room into the room), and the fire extinguishing agent reaches the hidden position when viewed from above the table or desk installed in the room, etc., to surely suppress the fire. Make it possible to extinguish a fire.

Here, "fire suppression and extinguishing" is a combination of the concept of suppressing a fire and another concept of extinguishing a fire. For example, fire suppression is a concept that suppresses the spread of fire, the burning speed of a fire, or the scale of a fire, and extinguishing a fire is a concept that extinguishes combustion. Of course, it also includes the case of either one.

(Effect of seat deployment in the event of a fire)
In addition, since the sheet provided with the fire extinguishing agent distribution channel and the discharge port has flexibility, in a normal state, for example, the sheet is unfolded at a predetermined position at the boundary of the protected area, for example, rolled in a roll state, and the upper part on the wall surface side of the room. Since it is installed in, the installation space is small.

In addition, by releasing the holding of the sheet in the event of a fire, the other end of the sheet with one end fixed falls downward and expands from the top to the bottom, and the fire extinguishing agent is deployed from the discharge ports arranged in various places of the deployed sheet. It is possible to suppress the extinguishing of fires by releasing the surface.

(Effect of sheet unfolding operation by supplying fire extinguishing agent)
In addition, the undeployed state of the sheet can be released and deployed by using the flow pressure of the fire extinguishing agent supplied at the time of a fire as a drive source. In addition, since the electric holding release operation is not required, the sheet can be reliably deployed and the fire extinguishing agent can be released even in the event of a power failure.

(Effect of fixed installation of deployment sheet)
In addition, the sheet may be installed on the wall surface of a room that serves as a protective area in the unfolded state (opened state) from the beginning, and when a fire breaks out, the fire extinguishing agent is surface-discharged from a plurality of discharge ports arranged in various places on the sheet. Enables fire extinguishing suppression.

(Effect of sheet structure 1)
In addition, the fire extinguishing agent distribution route and the structure of the sheet in which the crushable and deformable sheet piping in which the fire extinguishing agent supply port and the discharge port are arranged are arranged between the two cover sheets (first cover sheet and second cover sheet) A flexible sheet with an outlet can be manufactured easily and easily at low cost.

(Effect of seat structure 2)
Further, the first cover sheet, the first tarpaulin, the second tarpaulin, and the second cover sheet may be sewn in a laminated state so as to form a fire extinguishing agent distribution channel in which the fire extinguishing agent supply port and the fire extinguishing agent discharge port are arranged. Therefore, the formation of the fire extinguishing agent distribution route and the integration of the laminated sheets are realized at the same time by stitching, and a flexible sheet having the fire extinguishing agent distribution route and the discharge port can be produced more easily and easily, and mass production is also easy. Therefore, the manufacturing cost can be further reduced.

Further, as the fire extinguishing agent distribution route, an arbitrary route pattern can be easily and easily formed by, for example, suturing using a sewing machine or bonding using an adhesive.

(Effect of cover sheet)
Further, since the cover sheets (first cover sheet, second cover sheet) have fire resistance, fire resistance, heat resistance, heat insulation, flame insulation or smoke insulation, even if they receive heat or flame from a fire. It is possible to continue the release of the fire extinguishing agent without burning, and when it is installed and deployed at an opening such as an entrance / exit that is the boundary of the protected area, flame insulation and heat insulation to the outside of the protected area, Smoke insulation makes it possible to prevent the spread of fire and secure an evacuation route. In addition, the flexibility of the cloth-like body enables evacuation from inside the protected area to the outside even after the sheet is deployed.

(Effect of wetting the sheet with a fire extinguisher)
Further, for example, in creating a fire extinguishing agent distribution route by stitching or bonding, the fire extinguishing agent flows out of the fire extinguishing agent distribution route as a cooling agent to wet the sheet, thereby improving the flame-shielding property, smoke-shielding property, and heat-shielding property of the sheet. Can be improved.

(Effect of arrangement of fire extinguishing agent distribution channel on discharge port row)
Further, by supplying the fire extinguishing agent from both ends of the discharge port row elements in which a plurality of discharge ports are arranged along the horizontal direction of the sheet, for example, the discharge pressures of the plurality of discharge ports are made substantially uniform, and the fire extinguishing agent discharge pattern ( It is possible to align the emission amount with the angular distribution).

(Effect of installation location of fire extinguishing equipment)
In addition, the fire extinguishing device is placed at an arbitrary position as required, such as the entrance / exit of a room, a wall surface, a window, or a ceiling surface, which is the boundary of a protected area, for example, the seat surface is the boundary of the boundary in the unfolded state of the sheet. By locating along the surface, the seat can be easily and easily installed and used in the undeployed state or the unfolded state, and it is possible to install the optimum fire extinguishing device suitable for the usage pattern of the room.

(Effect of pressure buffering means)
When the fire extinguisher is opened and the fire extinguisher is supplied to the fire extinguisher distribution channel, the accumulated pressure of the fire extinguisher is as high as 0.7 MPa to 0.98 MPa, and the fire extinguisher is extinguished when the fire extinguisher is opened. Since high-pressure fire extinguisher may be damaged when a high-pressure fire extinguisher is added to the agent flow path, a fire extinguisher can be extinguished by providing, for example, a buffer area as a pressure buffering means on the inlet side of the fire extinguisher flow path. Prevent damage to the fire extinguishing agent distribution channel and outlet by setting the increase (or rate of increase) of the agent supply pressure to a predetermined value or less. Further, by providing a second pressure buffering means such as a tank or an orifice at the fire extinguishing agent supply port, similarly, the increase (or rate of increase) of the extinguishing agent supply pressure from the fire extinguisher is set to a predetermined value or less, and the extinguishing agent is distributed. Prevent damage to routes and outlets.

(Effect of fire extinguishing equipment 1 using water pipes)
In addition, by connecting a water pipe to the fire extinguishing agent pipe and discharging tap water as a fire extinguishing agent from the outlet of the fire extinguisher, a dedicated pump facility is not required, installation is easy, and cost can be reduced. ..

(Effect of fire extinguishing equipment 2 using a fire extinguisher)
In addition, a fire extinguisher supply device, such as a fire extinguisher nozzle, is connected to the fire extinguisher supply port via a fire extinguisher pipe, and when a fire breaks out, the fire extinguisher is opened to perform a predetermined fire extinguisher, for example, powder fire extinguisher or strengthening. By discharging the liquid fire extinguisher from the outlet of the fire extinguisher into the protected area, it is possible to effectively suppress and extinguish the fire.

Even if you are unfamiliar with handling a fire extinguisher, which is a fire extinguishing agent supply device, you can simply pull out the safety pin of the fire extinguisher located outside the room, which is a protective area, and hold the lever. Then, a high-pressure fire extinguisher, such as powder fire extinguisher, is supplied to the fire extinguisher installed in the room, and at the same time as the sheet is unfolded, the powder fire extinguisher is released over a wide range from the outlet of the fire extinguisher to suppress and extinguish the fire for a short time. It is possible to do it effectively with.

(Effect of fire extinguishing equipment 3 that uses both fire extinguisher and water pipe)
Further, in addition to the effects of the fire extinguisher 1 using the water pipe and the fire extinguisher 2 using the fire extinguisher described above, when a fire occurs, a fire extinguisher supply device, for example, a fire extinguisher is opened to open the fire extinguisher, for example, a powder. By releasing a fire extinguisher or a strengthening liquid fire extinguisher into the protected area from the discharge port of the fire extinguisher, the initial fire extinguisher is performed, and the fire extinguisher releases the fire extinguisher for a short time, for example, a dozen seconds. If the fire extinguishing is insufficient, tap water is discharged from the discharge port into the protected area by opening the pipe opening / closing means to continue the fire extinguishing, and the tap water is released in a timely manner. Since there are no restrictions, it is possible to reliably extinguish a fire suppressed by the release of a fire extinguisher from a fire extinguisher.

(Effect of the configuration of piping opening / closing means)
In addition, in the fire extinguishing equipment 1 or 3, the remote on-off valve is opened by remote control based on the control signal from the fire detection equipment when a fire occurs in the protected area, so that the fire extinguisher is linked to the fire detection from the outlet of the fire extinguisher. It is possible to release the fire extinguishing agent from the fire extinguisher, and it is also possible to release the fire extinguishing agent from the fire extinguisher by manually opening the on-off valve.

(Effect of connecting means of fire extinguisher)
In addition, since the fire extinguisher is detachably connected to the fire extinguishing agent piping by a connecting means, when the fire extinguisher is used up, it can be replaced with an unused fire extinguisher if necessary. Continues the release and enables reliable suppression and extinguishing of fire. Furthermore, if a plurality of connecting means with a check valve structure are provided and a fire extinguisher is connected to each of them, the trouble of attaching and detaching the fire extinguisher and replacing the fire extinguisher can be saved, and the fire extinguishing agent can be released promptly and surely suppressed. Allows fire extinguishing.

In addition, when a fire breaks out in a place outside the protected area where no fire extinguisher is installed, the fire extinguisher can be removed by the connecting means of the fire extinguishing agent pipe and carried to the place for use. A fire extinguisher and a fire extinguisher for fire extinguishing equipment can be used together, facilitating maintenance of the fire extinguisher and reducing operating costs.

(Effect of the second pressure buffering means of the fire extinguishing agent supply system)
Further, in the fire extinguishing equipment 2 or 3, a second pressure buffering means is provided in the connecting means of the fire extinguishing agent supply system or the fire extinguishing agent pipe, and the fire extinguisher supply pressure rises (or the rate of rise) from the fire extinguisher is set to be equal to or less than a predetermined value. Prevent damage to the agent distribution channel and outlet.

(Effect of fire extinguishing equipment in the warehouse)
According to the fire extinguishing equipment of the warehouse of the present invention, for example, when an article stored in an arbitrary storage part of the storage shelf ignites and becomes a fire, the sheet of the fire extinguisher provided on the storage shelf is unfolded and the storage shelf is opened. The opening surface corresponding to the boundary of the predetermined target section including the place where the fire broke out is partitioned and closed, and the fire extinguishing agent is surface-discharged into the target section from a plurality of discharge ports provided in various places of the unfolded sheet, and the installation place is set as the discharge point. Compared to the point emission of the conventional sprinkler bed, it can be sprayed efficiently over a wide area inside the target area, and by reducing water damage outside the target area (damage caused by the application of fire extinguishing agent), as a whole. , It is possible to suppress and extinguish a fire with a smaller amount of fire extinguishing agent released than before.

In addition, by unfolding the sheet of fire extinguisher provided on the storage shelf and partitioning and closing the opening surface of the predetermined target section including the place where the fire occurred on the storage shelf, flame and smoke can be shielded from inside the target section to the surroundings. By shielding the heat, the effect of preventing the spread of fire and the spread of smoke can be expected, and the synergistic effect of releasing the fire extinguishing agent into the target section from the openings provided in various parts of the sheet can further enhance the suppressed fire extinguishing performance. Furthermore, it is possible to suppress the dissipation and release of the fire extinguishing agent released into the partition compartment to the surroundings, and for example, to reduce the water damage of the articles stored in the surroundings.

In addition, since fire extinguishing equipment is installed on the storage shelf, it is not necessary to transport the fire extinguishing nozzle to the place where the fire broke out by a transport means such as a stacker crane, unlike the fire extinguishing equipment of a conventional warehouse, and a short time after the fire broke out. It is possible to suppress and extinguish a fire by releasing a fire extinguishing agent.

(Effect of target section)
In addition, the fire extinguisher is provided corresponding to the opening surface of the storage unit (rack) or the storage unit row (rack row) composed of a plurality of storage units, excluding the structural surface, and is provided in the storage unit or the storage unit row. By partitioning the opening surface of the storage section or the storage section row when a fire breaks out in, the storage section or the storage section row as seen from the fire source will be closed almost without gaps in addition to the structural surface. By releasing the fire extinguishing agent to the inside in this state, it is possible to efficiently suppress and extinguish the fire.

(Effect of fire detection and seat deployment)
Further, since the sheet deploying means provided in the fire extinguisher normally holds the sheet in the undeployed state, it does not hinder the loading or unloading of the article into the storage portion of the storage shelf by the transporting means. , In the event of a fire, by supplying a fire extinguisher to the fire extinguisher of the target section where the fire was detected by the fire detection means, the undeployed state of the sheet is released and the target section where the fire is occurring is expanded. Since the fire extinguishing agent is released in a partitioned and closed state, it is possible to quickly and surely suppress and extinguish the fire.

A discharge port is provided. Here, as shown in the drawing, the protection section 10 of FIG. 1 is perpendicular to the vertical direction, the height direction, and the vertical direction with the ceiling surface on which the fire detector 14 is installed as the upper direction, and the boundary of the room. The direction connecting the left and right wall surfaces when viewed from the doorway 11 (opening) is referred to as the left-right direction or the lateral direction, and the direction from the doorway 11 toward the inside of the room is referred to as the depth direction.

A fire detector 14 is connected to the receiver 16 as a fire detection facility in the protection zone 10. A fire extinguishing agent pipe 20 is connected to the fire extinguisher 12 from the water pipe 18 of the water supply facility via a sluice valve 25. A remote on-off valve 24 and a manual on-off valve 26 are connected in parallel to the fire extinguishing agent pipe 20 as a pipe opening / closing means for opening / closing the pipe flow path by remote control or manual operation. Here, the fire extinguishing equipment of the present embodiment includes a fire extinguisher 12, a fire extinguishing agent pipe 20, a remote on-off valve 24, a manual on-off valve 26, and a water pipe 18.

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 protection zone 10, it outputs a control signal (open control signal) to the remote on-off valve 24 to open the remote on-off valve 24. Then, tap water is supplied to the fire extinguisher 12 as a fire extinguishing agent.

When the remote on-off valve 24 is opened to supply tap water to the fire extinguisher 12, the seat unfolding portion described later operates to release the holding of the seat 28 and closes the doorway 11 of the protective compartment 10 as shown in FIG. As described above, one end of the sheet 28 is expanded from the upper side to the lower side (vertical direction), and at the same time, tap water is supplied to the fire extinguishing agent flow path of the sheet 28, and tap water is discharged into the protective compartment 10 from the plurality of discharge ports 30. , Suppress and extinguish the fire.

When a fire breaks out in any of the protected areas 10 (10-1, 10-2 ... 10-n), the corresponding fire detector 14 issues a fire signal and transmits a fire signal to the receiver 16. 16 outputs a control signal (open control signal) to the remote on-off valve 24 corresponding to the protected area where the fire broke out based on the fire signal to open the fire extinguisher 12 and extinguishes the fire extinguisher 12 installed in the protected area where the fire broke out. The agent (tap water) was supplied, and as shown in FIGS. 2 and 3, the sheet 28 of the fire extinguisher 12 was unfolded, and the fire extinguishing agent (tap water) was deployed from a plurality of outlets 30 arranged at various locations on the unfolded sheet 28. ) Is released to the surface to suppress and extinguish the fire.

[C. Fire extinguishing equipment sheet]
(C1. Sheet structure)
The sheet 28 (28a) of the present embodiment shown in FIG. 5 is a rectangular sheet having vertical and horizontal lengths corresponding to the installation location of the protective section, for example, the size of the doorway in the deployed state, and is flexible by using a cloth-like body. It has the property and can be easily put into an undeveloped state by winding it in a roll shape.

A fire extinguishing agent supply port 32 serving as an inlet for the fire extinguishing agent is arranged on one end side (upper end side) of the sheet 28, a fire extinguishing agent distribution path 34 shown by a dotted line is provided inside, and a plurality of fire extinguishing agents are released at various locations in the fire extinguishing agent distribution path 34. The exit 30 is arranged. In this embodiment, the discharge ports 30 are arranged at nine locations in three rows and columns.

Further, the fire extinguishing agent flow path 34 is formed in a four-stage ladder shape in the vertical direction (flow direction of the fire extinguishing agent), and the fire extinguishing agent supply port 32 is provided in the center of the first stage, which is the uppermost stage, from the second stage. For example, three discharge ports 30 are arranged in the fourth stage.

Horizontal discharge port rows of discharge ports 30 arranged in the second to fourth stages (the discharge port rows arranged horizontally in each stage are one discharge port row element, and the discharge port row elements are from the second stage. The fire extinguishing agent flow path 34 is formed so as to supply the fire extinguishing agent from both ends of each discharge port row element, whereas the fire extinguishing agent flow path 34 is arranged in three rows in the fourth row to form the entire discharge port row. As a result, the discharge pressure of the fire extinguishing agent supplied to the plurality of discharge ports 30 in the same row can be made substantially uniform, and the discharge pattern (angle distribution) and the discharge amount in the same row can be made uniform.

The form of the fire extinguishing agent distribution channel 34 for supplying the fire extinguishing agent to the plurality of discharge ports 30 is not limited to the ladder shape shown in the figure, and includes an appropriate form such as a tree shape and a tournament shape. Further, when the discharge pressures of the plurality of discharge ports 30 are made substantially uniform, the thickness (cross-sectional area) of the fire extinguishing agent distribution path 34 is increased on the fire extinguishing agent supply port 32 side, and the farther away from the fire extinguishing agent supply port 32. You may make it thinner. Further, the number and arrangement form of the discharge ports 30 provided corresponding to the fire extinguishing agent distribution path 34 are arbitrary.

(C2. Sheet manufacturing method 1)
The sheet 28 (28a) of the present embodiment shown in FIG. 5 is manufactured by, for example, the method shown in FIG. First, a first cover sheet 36 and a second cover sheet 38 having a predetermined size are prepared. The first cover sheet 36 and the second cover sheet 38 are cloth-like bodies having, for example, fire resistance, fire resistance, heat resistance or flame retardancy, and can withstand high heat of, for example, 1200 ° C. , Fireproof curtains, etc. can be applied, but are not limited to this. Further, the first cover sheet 36 and the second cover sheet 38 also have heat-shielding property, flame-shielding property, smoke-shielding property and the like, respectively. It should be noted that it does not prevent only the cover sheet facing the inside of the protective section from having fire resistance, fire resistance, heat resistance, flame retardancy, heat insulation, or flame insulation.

Subsequently, here, for example, a seat pipe 40 having a four-stage ladder shape is prepared. The seat pipe 40 is formed by forming a cloth-like body such as polyester used for umbrella tensioning in a pipe shape and connecting it in a ladder shape (the connection portion can be distributed), as shown in FIG. 7 (A). In addition, it is crushable and deformable, becomes flat by crushing, and when the fire extinguishing agent 41 is supplied, it swells as shown in FIG. 7B to form a fire extinguishing agent distribution path 34.

Further, as shown in FIG. 6, a fire extinguishing agent supply port 32 and a discharge port 30 are arranged in the sheet pipe 40, and a through hole 56 is opened in the first cover sheet 36 corresponding to the discharge port 30.

The discharge port 30 has, for example, the structure shown in FIG. The discharge port 30 is composed of a base 42 and a sandwiching ring 44. A screw shaft 46 is erected on the base 42, and a discharge hole 50 is penetrated through the screw shaft 46. The sandwiching ring 44 has a screw hole 48 and is screwed and fixed to the screw shaft 46.

As shown in FIG. 8A, the base 42 is arranged in the seat pipe 40 and is adhesively fixed by the adhesive portion 43 as shown in FIG. 8C, for example, and the screw shaft 46 is taken out to the outside. The screw shaft 46 taken out from the opening provided in the seat pipe 40 is taken out through the through hole 56 (see FIG. 6) of the first cover sheet 36, and the sandwiching ring 44 is screwed into the through hole 56 to screw the seat pipe 40 into the first cover sheet. It is sandwiched and fixed in a state where it is arranged on the back surface of 36.

Subsequently, as shown in FIG. 6, a seat pipe 40 provided with a discharge port 30 and a fire extinguishing agent supply port 32 is arranged on the back side of the first cover sheet 36, and the first cover sheet 36 sandwiches the sheet pipe 40. A second cover sheet 38 is arranged on the opposite side, and the first cover sheet 36 and the second cover sheet 38 are sewn together with a sheet pipe 40 in between and the sheet 28 shown in FIG. (28a) is completed.

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 the water pressure of tap water supplied as a fire extinguishing agent is about 0.02 MPa. Therefore, for example, 3 The hole diameter should be about 4 mm.

A hole diameter of about 3 to 4 mm corresponds to one hole diameter of a plurality of water discharge holes formed in a general shower head using tap water. Therefore, a tap water discharge pattern corresponding to one of the holes of the shower head can be obtained from the discharge port 30, and by discharging this discharge pattern from a plurality of discharge ports 30 arranged at various places on the sheet 28, the tap water can be discharged. It becomes surface emission as a whole.

The discharge hole 50 also functions as a nozzle that determines the discharge pattern of the fire extinguishing agent. For example, the straight discharge hole 50 shown in the figure has a relatively narrow-angle discharge pattern, and when the outlet opening of the discharge hole 50 is widened in a conical shape, a wide-angle discharge pattern that spreads in a conical shape is obtained, depending on the required discharge pattern. Make an appropriate opening shape. Discharge ports 30 having different opening shapes may be appropriately mixed.

In the present embodiment, the central axis (dashed line in the figure) of the discharge hole 50 is perpendicular to the seat surface, but the present invention is not limited to this. For example, the directivity of fire extinguishing agent release can be adjusted by adjusting the inclination angle of the central axis with respect to the seat surface.

Further, 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, a coolant discharge port is provided in the sheet pipe 40 constituting the fire extinguishing agent flow path. It may be provided separately from the seat pipe 40, or a coolant sheet pipe branching from the seat pipe 40 to form a coolant flow path may be provided, and a coolant discharge port may be provided therein. As a result, the fire resistance, fire resistance, heat resistance, etc. of the first cover sheet 36 and the second cover sheet 38 are improved, and a low grade sheet can be used, so that the cost can be reduced.

As the sheet 28 (28b) of FIG. 9, a first cover sheet 36, a first waterproof sheet 52, a second waterproof sheet 54, and a second cover sheet 38 of a predetermined size are prepared. The first cover sheet 36 and the second cover sheet 38 are the same as the manufacturing method of FIG. 6, and the first waterproof sheet 52 and the second waterproof sheet 54 are the same as the seat piping 40 of the manufacturing method of FIG. 6, for example, an umbrella. A cloth-like body such as polyester used for tensioning.

A fire extinguishing agent supply port 32 is arranged in the first waterproof sheet 52 corresponding to the fire extinguishing agent distribution path 34 to be formed, and through holes 56 and 58 are formed corresponding to the discharge port 30.

The first cover sheet 36 and the first waterproof sheet 52 are fixed by attaching the discharge port 30 as shown in FIG. 10 in a state where the through holes 56 and 58 are aligned and overlapped. The structure of the discharge port 30 is the same as that shown in FIG. 8, and is composed of a base 42 in which a screw shaft 46 penetrating the discharge hole 50 is erected and a sandwiching ring 44 having a screw hole 48.

As shown in FIG. 9, the second waterproof sheet 54 and the second cover sheet 38 are overlapped with each other in a state where the first cover sheet 36 and the first waterproof sheet 52 are fixed by the discharge port 30, and in this state, the second cover sheet 38 is shown in FIG. As described above, for example, the suture portion 60 is formed by suturing work with a sewing machine or the like using a waterproof thread, and the fire extinguishing agent flow path 34 is created. Further, the sheets 28 are integrated by the sewn portion 61 in which the peripheral edges of the sheets are sewn in the state where the sheets are overlapped.

FIG. 12A shows a first cover sheet 36, a first tarpaulin 52, a second tarpaulin 54, and a second cover sheet 38 in a state of being overlapped, and is formed by a suture portion 60 sewn with a sewing machine using, for example, a waterproof thread. The fire extinguishing agent distribution channel 34 is normally in a crushed state, and when the fire extinguishing agent 41 is supplied, it swells as shown in FIG. 12B to distribute the fire extinguishing agent.

Here, the airtightness of the fire extinguishing agent distribution path 34 is improved by making the sutured portion 60 double, but when tap water is supplied as the fire extinguishing agent, a small amount may leak from the seam. However, the tap water leaking from the fire extinguishing agent distribution channel 34 wets the sheet 28, which improves fire resistance, fire resistance, heat resistance, heat insulation, flame insulation or smoke insulation.

As described above, 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, a cooling agent is provided in the fire extinguishing agent distribution path 34 formed by the suture portion 60. A discharge port may be provided. The coolant discharge port adjusts the suture portion 60 forming the fire extinguishing agent flow path 34 so that the seams are partially enlarged, or partially skips the seams and sutures, or partially increases the seam spacing. Then, this gap may be used as a coolant discharge port. Further, a flow passage (cooling flow passage) provided with a coolant discharge port may be provided separately from the fire extinguishing agent flow passage. Although the fire extinguishing agent also serves as a coolant here, the fire extinguishing agent and the coolant may be different. In this case, a coolant pipe may be provided separately from the fire extinguishing agent pipe, and a coolant supply port having a similar configuration may be provided separately from the fire extinguishing agent supply port to connect to the coolant pipe.

The fire extinguisher may continue to be released without replacing the finished fire extinguisher.

In addition, when a fire breaks out in a place other than the protection zone 10 (a place where the fire extinguisher 12 of the present embodiment is not installed), remove the fire extinguisher 84 from the fire extinguishing agent pipe 20 and carry it to the fire extinguishing place for use. Therefore, it is not necessary to increase the number of fire extinguishers installed, and the increase in maintenance cost is reduced.

[F. Fire extinguishing equipment that combines a fire extinguisher and water pipes]
As shown in FIG. 18, in the present embodiment, the fire extinguisher supply source of the fire extinguisher 12 installed at the boundary of the room serving as the protection zone 10, for example, the upper part of the doorway, is used as a fire extinguisher, for example, a powder fire extinguisher or a strengthening liquid fire extinguisher. The fire extinguisher 84 for supplying fire extinguisher and the water pipe 18 for supplying tap water as a fire extinguishing agent are used in combination.

One end side of the fire extinguishing agent pipe 10 is connected to the fire extinguishing agent supply port 32 of the sheet 28 (28c), and the other end side is a remote on-off valve 24 connected in parallel, which is a pipe opening / closing means for opening and closing the pipe flow path by remote control or manual operation. Is connected to the water pipe 18 via the manual on-off valve 26.

Further, the backflow of tap water from the fire extinguisher pipe 20 side to the fire extinguisher 84 side is prevented in the pipe branched from one end side of the fire extinguisher pipe 20 and between the remote on-off valve 24 and the manual on-off valve 26 (point A in the figure). A fire extinguisher 84 is connected via a check valve 98 as a backflow prevention means, and a fire extinguisher connecting portion 94 as a connecting means for detachably connecting the fire extinguisher 84 to the fire extinguisher pipe 20 is provided. .. The fire extinguisher connecting portion 94 is composed of a fire extinguisher nozzle 94a and a fire extinguisher connecting port 94b, and has a connecting joint structure similar to that shown in FIG. 16, for example.

A fire detector 14 is installed in the protection zone 10 as a fire detection facility and is connected to the receiver 16. An alarm indicator light 16a is installed near the installation location of the fire extinguisher 84 and is connected to the receiver 16. When the receiver 16 receives the fire signal from the fire detector 14 and outputs the fire alarm, the fire alarm light 16a lights up or blinks in response to the control signal from the receiver 16 linked to the fire alarm light 16a to extinguish the fire. Is a display means for displaying an installation location of a fire extinguisher 84 that requires or can be operated to extinguish a fire. Further, the control line of the remote on-off valve 24 is connected to the receiver 16. Here, the fire extinguishing equipment of the present embodiment includes a fire extinguisher 12, a fire extinguishing agent pipe 20, a fire extinguisher 84, a fire extinguisher connecting portion 94, a check valve 98, a remote on-off valve 24, a manual on-off valve 26, and a water supply pipe 18. It is composed.

For example, the receiver 16 can set an automatic fire extinguishing mode and a manual fire extinguishing mode. The automatic fire extinguishing mode is set to, for example, at night, and the remote on-off valve 24 is based on the control signal (open control signal) from the receiver 16 linked to the fire detection (fire alarm of the receiver) of the fire detector 14. The fire extinguishing agent is released by controlling the opening of the fire extinguisher. The manual fire extinguishing mode is set, for example, during the daytime, and the fire extinguishing agent is released by opening the fire extinguisher 84 or opening the manual on-off valve 26. In addition to switching the manual fire extinguishing mode / automatic fire extinguishing mode during the daytime / nighttime, the manual fire extinguishing mode / automatic fire extinguishing mode may be switched according to the presence / absence of a person. You may combine them.

When the manual fire extinguishing mode is set for the receiver 16, 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 a fire breaks out. The alarm indicator light 16a installed corresponding to the protection zone 10 is turned on or blinks.

A person concerned who learned of the fire went to the protected area 10 where the fire broke out, and when he confirmed the fire, he pulled out the safety pin 90 of the fire extinguisher 84 and pushed down the lever 92 to open it, and extinguished the fire extinguisher from the fire extinguisher 84. The sheet 28 (28c) is unfolded by supplying it to the appliance 12, and powder fire extinguishing agents and the like are surface-discharged from a plurality of discharge ports 30 arranged in various places of the sheet 28 (28c) to suppress and extinguish a fire.

If the fire extinguishing cannot be confirmed even after the fire extinguisher 84 has been discharged, the manual on-off valve 26 is opened to supply tap water to the fire extinguisher 12, and the unfolded sheet 28 (28c) is used. Tap water is discharged from a plurality of discharge ports 30 arranged in various places to suppress and extinguish a fire. The tap water is released after the fire is suppressed by the release of the fire extinguisher from the fire extinguisher 84, and since the tap water is released without time constraints, it is possible to surely extinguish the fire. To do.

On the other hand, when the automatic fire extinguishing mode is set in the receiver 16, the receiver 16 that receives the fire signal from the fire detector 14 transmits the open control signal to the remote on-off valve 24 to open the fire, and tap water is discharged. The fire extinguishing device 12 is supplied, the sheet 28 (28c) is deployed, and tap water is surface-discharged from a plurality of discharge ports 30 arranged at various locations on the sheet 28 (28c) to suppress and extinguish the fire.

Even in the automatic fire extinguishing mode, for example, when a person who rushes to receive a fire report finds out that the momentum of the fire has not diminished, for example, the remote on-off valve 24 is used in the receiver 16. After performing a predetermined operation of closing the fire extinguisher, for example, canceling the automatic fire extinguishing mode and setting the manual fire extinguishing mode, the fire extinguisher 84 is opened by pulling out the safety pin 90 and pushing down the lever 92, and extinguishing the fire from the fire extinguisher 84. The agent is supplied to the fire extinguisher 12, and the extinguishing agent is surface-discharged from a plurality of discharge ports 30 arranged at various places on the unfolded sheet 28 (28c), so that the fire can be suppressed and extinguished.

In this way, after the fire extinguisher 84 is discharged, the manual on-off valve 26 can be opened again to switch to tap water discharge again.

[H. Basic concept of warehouse fire extinguishing equipment]
The basic concept of the embodiment of the fire extinguishing equipment of the warehouse using the fire extinguishing equipment shown in FIGS. 5 to 14 will be described.

The warehouse where the fire extinguishing equipment is installed is equipped with storage shelves and transportation means. The "storage shelf" is a shelf in which a plurality of storage units are arranged, and is a concept including, for example, a rack shelf in which a plurality of racks are arranged side by side in the vertical direction and the horizontal direction.

Further, the "transporting means" is a means for transporting a target article and taking it in and out of the storage section (carrying it in or out of the storage section), and is a concept including, for example, a so-called stacker crane. ..

The fire extinguisher is arranged so as to partition a predetermined target section including the fire occurrence location of the storage shelf and discharge the fire extinguishing agent into the target section. Here, the "target section" in the following embodiment of the fire extinguishing equipment of the warehouse is an area section to be extinguished, that is, for example, a predetermined section of the storage shelf where a fire is occurring. Storage shelves are classified into storage shelves without a partition structure in the vertical direction (height direction) and storage shelves with a partition structure depending on the presence or absence of shelf boards. Here, in the case of a storage shelf having a partition structure, the storage section (internal space of the storage section) itself, for example, a predetermined rack (internal space of the rack) is targeted, while in the case of a storage shelf without a partition structure, the storage section is targeted. A case will be described in which a storage unit row (internal space of the storage row) in which a plurality of storage units are arranged in the vertical direction, for example, a predetermined rack row (internal space of the rack row) is targeted.

In addition, the rack or rack row is configured with the closed upper and lower structural surfaces and the open surfaces of other openings (excluding the upper and lower sides) as boundaries, and fire extinguishing equipment is provided corresponding to the open surfaces. Has been done. In the embodiment of the fire extinguishing equipment of such a warehouse, when the target section is, for example, a rack or a rack row, "dividing the target section" means unfolding a sheet of fire extinguishing equipment to close at least the opening surface of the rack or the rack row. Therefore, it is a concept that all the surfaces forming the boundary of the rack or the rack row (for example, in the case of a rectangular shape, all the six boundary surfaces) are closed with almost no gap together with the structural surface other than the opening surface (however, the inside is closed). It does not have to be completely sealed).

Hereinafter, the "storage shelf" will be referred to as a "rack shelf", the "storage section" will be referred to as a "rack", the "storage section row" will be referred to as a "rack row" in which a plurality of racks are arranged vertically, and the "transport means" will be referred to as a "stacker". The case of an automated warehouse called "crane" will be described in detail.

[I. Specific details of warehouse fire extinguishing equipment]
(I1. Overview of automated warehouse)
As shown in FIG. 21, a rack shelf 110 is installed in the automated warehouse 100, and the present embodiment takes as an example a rack shelf 110 that does not have a partition structure by a shelf board. A plurality of racks 118 are arranged in the rack shelves 110 in the vertical direction and the horizontal direction, and articles are carried into and stored in an arbitrary rack 118 by a stacker crane 120, and the stored articles are carried out. Here, with respect to the rack shelf 110, as shown in the drawing, the vertical direction in which the side on which the top plate 114 is arranged faces upward is the vertical direction or the height direction, and the longitudinal direction of the top plate 114 orthogonal to the vertical direction is the horizontal direction or the horizontal direction. The lateral direction and the lateral direction are referred to as the front-rear direction or the depth direction.

In the rack shelf 110, a set of two columns 112 standing at predetermined intervals in the depth direction of the floor surface are erected laterally at predetermined intervals, and a top plate 114 is arranged at the upper end of each column 112. The rack shelves 110 form a rack row in which four columns 112 that are adjacent to each other are used as one unit, and racks 118 having four stages are arranged in the vertical direction.

That is, as shown in FIGS. 21 and 22, a pair of rack rails 116 are arranged in parallel in the depth direction, and these rack rails 116 are provided at predetermined intervals in the vertical direction to form a four-stage rack 118. The rack 118 is loaded on the pallet (loading platform) 130 by the stacker crane 120, and the articles are carried into the rack 118 and also carried out from the rack 118.

Since the rack rows formed in this way do not have shelves that partition the vertical direction, they form a rack space that penetrates in the vertical direction when the articles are not stored.

The stacker crane 120 has a gate-shaped crane frame 124 mounted on a traveling bogie 122 traveling left and right along the traveling rail 132, and the upper side of the crane frame 124 is guided by a ceiling rail 134. The crane frame 124 is provided with an elevating table 126 and is equipped with two sets of fork transfer devices 128, which can move the elevating table 126 up and down to transfer the pallet 130 to an arbitrary rack 118. It is said.

The delivery of goods to the rack 118 is as follows. First, the stacker crane 120 is moved along the traveling rail 132 to the traveling moving table 136 side and stopped. Further, the traveling moving table 136 is positioned along the traveling rail 135 at the carrying-in portion 138, and articles are loaded from the carrying-in portion 138 onto the pallet 130. Subsequently, the pallet 130 loaded with the articles is transferred to the fork transfer device 128 provided on the elevating table 126 by the fork device 141 of the traveling moving table 136. Finally, the stacker crane 120 is moved left and right along the traveling rail 132, and the elevating platform 126 is further moved up and down to carry the article into the target rack 118.

Further, the article is carried out from the rack 118 in the opposite operation to that at the time of the carry-in, and the article on the pallet 130 transferred to the traveling moving table 136 by the stacker crane 120 is carried out from the carry-out unit 140 to the outside of the warehouse.

(I2. Fire extinguishing equipment for rack rows)
Next, the fire extinguishing equipment for any rack row of the rack shelves 110 will be described in detail.

The rack row is closed at the upper end by a top plate 114 forming a structural surface, and at the lower end is closed by the floor surface of the warehouse forming the structural surface, and the remaining four side surfaces are open surfaces. The fire extinguishing device 12 is installed corresponding to the opening surface around the rack row. Specifically, as shown in FIG. 22, four fire extinguishing devices 12 are installed at the upper ends of the four columns 112 corresponding to the rack rows, for example, in a rectangular frame shape. There is. Here, the fire extinguishing device 12 corresponding to the left and right opening surfaces of the rack row is installed at the upper end of the support column 112 so that both ends in the longitudinal direction are substantially in contact with the front and rear columns 112 facing each other, and also in the present embodiment. In order to correspond to the adjacent racks 118, two units are arranged side by side for each pair of front and rear columns 112. It should be noted that these may be shared by one unit, and in this case, for example, the sheet 28 of the fire extinguisher 12 may be provided with independent fire extinguishing agent distribution channels 34 and discharge ports 30 on both sides thereof.

As shown in FIG. 23, a fire extinguishing agent pipe 20 from a fire extinguishing pump facility (not shown) is connected to each of the fire extinguishing devices 12 installed in this way via a remote on-off valve 24 for each rack row. Further, a fire detector (not shown) serving as a fire detection means is installed in each of the racks 118.

The operation when a fire breaks out in the rack 118 or the rack row is as follows. As shown in FIG. 24, if a fire breaks out in the rack row on the side closest to, for example, the carry-in portion 138 (see FIG. 21) of the rack shelf 110, four fire extinguishers arranged at the upper end of the rack row are extinguished. The appliance 12 unfolds the sheet 28, for example, by receiving a fire extinguishing agent, partitions and closes the opening surface of the rack row, which is the place where the fire occurs, and subsequently, as shown in FIG. 25, the inner sheet surface of the sheet 28 ( The fire extinguishing agent is discharged from the discharge port 30 represented by a triangle, which is arranged on the seat surface on the side facing the rack row.

Therefore, the front, rear, left, and right opening surfaces of the rack row including the place where the fire broke out are partitioned by the sheet 28, and the fire extinguishing agent is discharged into the rack row where the fire is occurring from the discharge ports 30 provided in various places of the sheet 28. This ensures that the fire is suppressed and extinguished. In addition, by partitioning the opening surface of the rack row including the place where the fire occurred, the outside of the partitioned rack row is flame-shielded, smoke-shielded, and heat-shielded to prevent fire spread and smoke diffusion. Dissipation and release to the outside can be suppressed, and for example, water damage to articles stored in adjacent rack rows can be reduced.

(I3. Fire extinguishing equipment for warehouses targeting racks)
Next, the fire extinguishing equipment of the warehouse for any rack 118 of the rack shelf 110 will be described in detail.

As shown in FIG. 26, the automated warehouse 100 according to the present embodiment takes as an example a case where a rack shelf 110 having a partition structure by a shelf board is installed. In the rack shelf 110, for example, four shelf boards 150 are arranged at predetermined intervals in the vertical direction in each of the rack rows of the rack shelves in FIG. 21, forming a four-stage rack 118.

Therefore, the top surface of the rack 118 at the top is closed by the top plate 114 and the bottom surface is closed by the shelf plate 150, and the top and bottom surfaces of the rack 18 in the second to fourth stages from the top are closed by the shelf plate 150. Has been done. Each rack has four remaining side surfaces as opening surfaces, and four fire extinguishers are extinguished on the upper end of the opening surface, that is, on the upper surface side of each rack in the same manner as in the case of installation in FIG. Each of the instruments 12 is installed on the side of the frame. A fire detector (not shown) is installed in each of the racks 118. Further, as shown in FIG. 23, fire extinguishing agent pipes are connected to the four fire extinguishing devices 12 arranged for each rack 118 via a remote on-off valve (not shown).

The operation when a fire breaks out in rack 118 is as follows. As shown in FIGS. 26 and 27, for example, if a fire breaks out in the rack 118 on the second stage from the bottom on the side closest to the carry-in portion 138 (see FIG. 21), it is arranged on the upper part of the rack 118. The four fire extinguishing devices 12 deploy the sheet 28, for example, by receiving a supply of a fire extinguishing agent, partition and close the opening surface around the rack 118, and the rack 118 is partitioned from a plurality of discharge ports 30 represented by triangles. Release the fire extinguishing agent inside.

For this reason, the front, rear, left, and right opening surfaces of the rack 118, which is the place where the fire occurs, are partitioned, and the fire extinguishing agent is discharged from the discharge port 30 of the unfolded sheet 28 into the rack 118 where the fire is occurring. Suppressed fire extinguishing is surely performed. In addition, by partitioning the opening surface of the rack 118, which is the place where the fire occurs, the outside of the partitioned rack 118 is flame-shielded, smoke-shielded, and heat-shielded to prevent fire spread and smoke diffusion, and further, a fire extinguishing agent. It is possible to suppress the dissipation and release of smoke to the outside, and for example, to reduce water damage to articles stored in adjacent racks or rack rows.

When a fire breaks out in any rack 118, for example, the fire extinguisher 12 is also operated to deploy the seat 28 with the other part or all of the rack 118 in the rack row including the rack 118. However, the fire extinguishing agent may be sprayed.
