In addition, for example, it is not necessary to provide a material (for example, a sheet metal) surrounding the fire extinguishing device on the entire surface of the fire extinguishing device housing means, so that the material cost for manufacturing the fire extinguishing device housing means can be reduced. . In addition, for example, it is not necessary to provide a material surrounding the fire extinguishing device (for example, a sheet metal) on the entire surface of the fire extinguishing device accommodating means, so that it is possible to reduce the weight of the fire extinguishing system, Installation can be improved. For example, since the fire extinguishing apparatus accommodated in the fire extinguishing apparatus accommodating means can be held, the fire extinguishing apparatus can be fixed at a predetermined position.

  According to the fire extinguishing system of the seventh aspect, by providing the attachment means, for example, it is possible to attach the electrical equipment related to the fire extinguishing apparatus. (For example, any electric device including a telephone set used for maintenance) can be used. In addition, for example, it is not necessary to provide an electrical facility for the predetermined electrical device separately from the fire extinguishing system, so that the space in the place where the fire extinguishing system is installed can be used effectively.

The moving shaft 462b2 is a moving means that moves relative to the fixed cylinder 462a1, for example, the lower end (−Z direction) of the moving shaft 462b2 is inserted into the fixed cylinder 462b1, and the moving shaft A handle handle 462a is fixed to the upper end (+ Z direction) of 462b2. The moving shaft 462b2 is moved by using a known mechanism so that, for example, by rotating the handle handle 462a, the moving shaft 462b2 moves in the vertical direction (Z direction) while rotating itself, and can open and close the on-off valve 461. , Provided inside the fixed cylinder 462b1

  Here, for example, with respect to the operation handle 462 including the handle handle 462a and the handle shaft 462b, the moving shaft 462b2 moves downward (−Z direction) by rotating the handle handle 462a clockwise, When the handle handle 462a moves to the non-interference position, the on-off valve 461 closes the flow path, while rotating the handle handle 462a counterclockwise, the moving shaft 462b2 moves upward (−Z direction). It will be described below that the on-off valve 461 is configured using a known mechanism or the like so that the opening / closing valve 461 opens the flow path when the handle handle 462a moves to the interference position.

(Operation)
Next, the operation of the fire extinguishing system 100 of FIG. 1 configured as described above will be described. Specifically, a fire extinguishing operation that is an operation for extinguishing fire and a maintenance operation that is an operation for performing maintenance will be described. In addition, the ground side fire hydrant valve 21, the underground side fire hydrant valve 22, and the simultaneous open valve 23 of FIG. 1 are closed, and the maintenance hose 32 is not attached as shown in FIG. The state in which the handle 462 is provided at the interference position and the on-off valve 461 has the flow path open is the initial state of the fire extinguishing system 100 when performing the fire extinguishing operation and the maintenance operation. A case where a maintenance operation is performed will be described. In addition, since well-known operation | movement can be applied about operation | movement of the automatic pressure regulating valve 24 of FIG. 1, the control drain valve 25, and the fire extinguishing drain valve 26, it abbreviate | omits about the description.

(Operation-Fire-extinguishing-Start)
When starting the fire extinguishing operation, the user on the ground in FIG. 1 activates the pump 42 by pressing a button on a transmitter (not shown) on the ground. In this case, the water in the water tank 41 is supplied by the pump 42 to a part of the fire-extinguishing pipe 11 on the upstream side of the simultaneous release valve 23 and the upstream control pipe 12.

  Next, the user on the ground opens the ground-side fire hydrant valve 21 after taking out the fire hose 31 from the fire hydrant storage box 101. In this case, the water supplied to the upstream control pipe 12 is supplied to the simultaneous release valve 23 via the ground-side fire hydrant valve 21 and the downstream control pipe 13, and pressure is supplied to the simultaneous release valve 23. Thus, the simultaneous release valve 23 opens the flow path of the fire extinguishing pipe 11. Next, the water that has been supplied to a part of the fire-extinguishing pipe 11 on the upstream side of the simultaneous opening valve 23 is supplied to the eductor 44 via the automatic pressure regulating valve 24, and the foam stock solution in the foam tank 43 is supplied by the eductor 44. And the foam is extinguished, and the foam is supplied to the supply unit 45 and the opening / closing unit 46. In this case, since the on-off valve 461 in FIG. 2 opens the flow path, the supplied foam extinguishing agent is supplied to the fire-extinguishing hose 31 in FIG. 1 through the on-off valve 461 and discharged from the fire-extinguishing nozzle. . In this case, since the maintenance hose 32 is not attached to the supply port 453, a closing valve (not shown) of the supply port 453 is closed, so that the foam extinguishing agent is not released from the supply port 453.

(Operation-Fire-extinguishing operation-End)
When ending the fire extinguishing operation, the user on the ground closes the ground-side fire hydrant valve 21 after pressing a pump stop switch (not shown). In this case, since the pump 42 is stopped and the upstream control pipe 12 and the downstream control pipe 13 are disconnected, the pressure supplied to the simultaneous release valve 23 decreases, and the simultaneous release valve 23 The flow path of the fire extinguishing pipe 11 is closed, and the release of the foam extinguishing agent from the fire extinguishing hose 31 is stopped. After that, after draining each pipe, the fire hose 31 is stored in the fire hydrant storage box 101. This completes the fire extinguishing operation.

(Operation-Maintenance operation-Start)
Next, when starting the maintenance operation, even if the user underground in FIG. 1 tries to attach the maintenance hose 32 to the supply port 453 in the state of FIG. 2, the maintenance hose 32 interferes with the operation handle 462. The following operations are performed. Specifically, the underground user rotates the handle handle 462a in FIG. 2 clockwise to move the operation handle 462 downward (−Z direction) so that the operation handle 462 moves to the non-interference position. Move to. When the operation handle 462 moves to the non-interference position, the on-off valve 461 closes the flow path, and the maintenance hose 32 can be attached to the supply port 453.

  Next, the underground user attaches the maintenance hose 32 to the supply port 453 as shown in FIG. In this case, a closing valve (not shown) inside the supply port 453 is opened by the tip of the maintenance hose 32 inserted into the supply port 453, and the foam extinguishing agent of the fire-extinguishing pipe 11 becomes the vertical pipe 451 and the horizontal pipe. It can be supplied to the maintenance hose 32 via 452. In this way, the maintenance hose 32 can be attached to the supply port 453 only when the operation handle 462 is moved to the non-interference position and the on-off valve 461 closes the flow path. Although the maintenance hose 32 is attached to 453, it can be prevented that the state where the on-off valve 461 opens the flow path is generated.

  Next, the underground user opens the underground fire hydrant valve 22 after starting the pump 42 by pressing a pump activation switch (not shown) underground. In this case, similarly to the case described in “(Operation−Fire Fighting−Start)”, the simultaneous release valve 23 opens the flow path of the fire fighting pipe 11, and the water in the water tank 41 is extinguished. Is supplied to the eductor 44 through the automatic pressure regulating valve 24 and is stirred with the foam stock solution in the foam tank 43 by the eductor 44 to become a foam extinguisher. 45 and the opening / closing part 46. In this case, since the on-off valve 461 of FIG. 4 closes the flow path and the closing valve (not shown) of the supply port 453 is open, the supplied foam extinguishing agent passes through the vertical pipe 451 and the horizontal pipe 452. To the maintenance hose 32 and discharged. Then, the underground user knows whether or not the foam extinguishing agent is discharged from the maintenance hose 32, and whether or not the fire extinguishing system 100 operates normally based on the discharge amount or the discharge time. It is possible to confirm using this method. In this case, since the on-off valve 461 closes the flow path, the foam extinguisher can be prevented from being released from the fire hose 31.

(Operation-Maintenance operation-End)
When the maintenance operation is finished, the underground user presses a pump stop switch (not shown) and then closes the underground fire hydrant valve 22. In this case, the pump 42 is stopped and the release of the foam extinguishing agent from the maintenance hose 32 is stopped in the same manner as the case described in “(Operation−Fire extinguishing operation−End)”.

  Next, after removing the maintenance hose 32 of FIG. 4 from the supply port 453, the underground user rotates the handle handle 462a counterclockwise so that the operation handle 462 moves to the interference position. The operation handle 462 is moved upward (+ Z direction). When the operation handle 462 moves to the interference position, the on-off valve 461 opens the flow path, and the maintenance hose 32 cannot be attached to the supply port 453. This completes the maintenance operation.

(Effect of embodiment)
As described above, according to the present embodiment, when the on-off valve 461 opens the flow path, the attachment of the maintenance hose 32 to the supply port 453 is obstructed, and the on-off valve 461 closes the flow path. By permitting the attachment of the maintenance hose 32 to the supply port 453, for example, the maintenance hose 32 can be attached to the supply port 453 only when the on-off valve 461 closes the flow path. Due to human error (for example, forgetting to close the flow path), the on-off valve 461 opens the flow path even though the maintenance hose 32 is attached to the supply port 453 In order to prevent the occurrence of a situation, when performing maintenance due to the human error, the fire hose 31 can be used. Can foam is prevented from being released, the maintenance reliably without disturbing the surroundings.

  Further, when the opening / closing valve 461 opens the flow path, the operation handle 462 moves to the interference position so as to hinder the attachment of the maintenance hose 32 to the supply port 453, and the opening / closing valve 461 closes the flow path. If the operation handle 462 and the maintenance hose 32 interfere with each other, for example, by moving to the non-interference position so as to permit the attachment of the maintenance hose 32 to the supply port 453, Since the attachment of the maintenance hose 32 to the supply port 453 can be inhibited or permitted, the open / close valve 461 opens the flow path even though the maintenance hose 32 is attached to the supply port 453. It is possible to reliably prevent the state from occurring.

  Further, since the attachment control means is the operation handle 462 for operating the on-off valve 461, for example, the function of the attachment control means can be realized by using parts of a conventional fire extinguishing system. Parts cost or modification cost for realizing the function can be reduced, and the fire extinguishing system 100 can be provided at a low price.

[Modifications to Embodiment]
Although the embodiments of the present invention have been described above, the specific configuration and means of the present invention can be arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. Can do. Hereinafter, such a modification will be described.

(About problems to be solved and effects of the invention)
First, the problems to be solved by the invention and the effects of the invention are not limited to the above contents, and may vary depending on the implementation environment and the details of the configuration of the invention. May be solved, or only some of the effects described above may be achieved.

(About distribution and integration)
The above-described configuration is functionally conceptual and does not necessarily need to be physically configured as illustrated. In other words, the specific forms of distribution and integration of the respective units are not limited to those shown in the drawings, and all or a part thereof can be configured to be functionally or physically distributed or integrated in arbitrary units. The “system” in the present application is not limited to one configured by a plurality of devices, but includes one configured by a single device. In addition, the “apparatus” in the present application is not limited to one configured by a single apparatus, but includes one configured by a plurality of apparatuses.

(About supply section and opening / closing section-configuration)
Moreover, although the case where the supply part 45 and the opening-and-closing part 46 of FIG. 2 were used was demonstrated in the said embodiment, you may use the supply part and opening-and-closing part different from the supply part 45 and the opening-and-closing part 46. FIG. FIG. 5 is a side view illustrating a modified example of the supply unit and the opening / closing unit in a state where the maintenance hose is removed in a state where the operation handle is moved to the interference position, and FIG. 6 is a plan view of FIG. FIG. 7 is a side view illustrating the supply part, the opening / closing part, and the maintenance hose virtually illustrated with the operation handle moved to the interference position, and FIG. FIG. 9 is a side view illustrating a supply part, an opening / closing part, and a maintenance hose of a modified example in a state where the handle is moved to the non-interference position, and FIG. 9 is a plan view of FIG. In the following description, the Y direction shown in FIGS. 6 and 9 will be described below as the direction orthogonal to the X direction and the Z direction.

  First, the supply unit 55 shown in FIGS. 5 and 6 is changed so that the length of the vertical pipe 451 in the supply unit 45 shown in FIG. 2 is shortened. The configuration is the same as the name. The supply unit 55 includes, for example, a vertical pipe 551, a horizontal pipe 552, and a supply port 553.

  5 and 6 implements the same function as the opening / closing part 46 of FIG. 2 with a configuration different from that of the opening / closing part 46. The opening / closing part 56 includes, for example, an opening / closing valve 561 and an operation handle 562 as shown in FIGS.

  The on-off valve 561 opens and closes by operating the operation handle 562, for example. When the opening / closing valve 561 opens the flow path, the operation handle 562 moves to an interference position to be described later so as to hinder the attachment of the maintenance hose 32 to the supply port 553, and the opening / closing valve 561 closes the flow path. In order to permit the attachment of the maintenance hose 32 to the supply port 553, the handle moves to a non-interference position described later, and includes a handle handle 562a and a handle shaft 562b, for example.

  Here, the “interference position” is a position of the operation handle 562 and a position that interferes with the maintenance hose 32 attached to the supply port 553, and is virtually illustrated in FIG. The operation handle 562 is at a position where at least a part of the operation handle 562 overlaps (that is, interferes) with the maintenance hose 32. For example, a handle handle 562 a described later of the operation handle 562 is provided in the vicinity of the supply port 553. An example is the position of the operation handle 562 shown in FIG. Further, the “non-interference position” is a position of the operation handle 562 that does not interfere with the maintenance hose 32 attached to the supply port 553, and is virtually illustrated in FIG. For example, the handle handle 562a (described later) of the operation handle 562 is away from the supply port 553. There is a position of the operation handle 562 shown in FIG. 9 as an example.

  The handle handle 562a shown in FIGS. 5 and 6 is an operation means operated by the user. For example, the handle handle 562a has a flat plate shape extending in the shape of a rod. The handle handle 562a is in the directions A1 and A2 in FIG. It is configured so that it can be rotated by 90 degrees.

  The handle shaft 562b in FIGS. 5 and 6 is support means for rotatably supporting the handle handle 562a, and also transmits a force for opening and closing the on-off valve 561 by rotating the handle handle 562a. For example, it is provided in the fire extinguishing pipe 11.

  For example, the operation handle 562 having the handle handle 562a and the handle shaft 562b is opened and closed when the handle handle 562a is moved to the non-interference position by rotating the handle handle 562a in the direction A1. The valve 561 closes the flow path, while the handle handle 562a is rotated in the direction A2 so that the on-off valve 561 opens the flow path when the handle handle 562a moves to the interference position. It is assumed to be configured using a mechanism or the like.

(About supply section and opening / closing section-maintenance operation)
In the fire extinguishing system of the modified example configured as described above (specifically, in the fire extinguishing system 100 of the embodiment, the supply unit 45 and the opening / closing unit 46 are replaced with the supply unit 55 and the opening / closing unit 56), the maintenance operation 5, even if the underground user tries to attach the maintenance hose 32 to the supply port 553 in the state shown in FIGS. 5 and 6, the maintenance hose 32 interferes with the operation handle 562 and installs it. The following operations are performed. Specifically, the underground user rotates the handle handle 562a in FIG. 6 in the direction A1, and moves the handle handle 562a to the non-interference position. When the handle handle 562a moves to the non-interference position, the on-off valve 561 closes the flow path, and the maintenance hose 32 can be attached to the supply port 553. Next, as shown in FIGS. 8 and 9, the underground user starts the maintenance operation by performing the same operation as described in the embodiment after attaching the maintenance hose 32 to the supply port 553. To do.

  Next, when the maintenance operation is finished, the underground user performs a predetermined operation (depressing a pump stop switch (not shown) described in the embodiment) and then the maintenance hose shown in FIGS. 8 and 9. After removing 32 from the supply port 553, the handle handle 562a is rotated in the direction A2 in FIG. 6 to move the handle handle 562a to the interference position. When the handle handle 562a moves to the interference position, the on-off valve 561 is in a state where the flow path is open, and the maintenance hose 32 cannot be attached to the supply port 553. This completes the maintenance operation.

(About mounting control means (1))
Moreover, although the case where the attachment control means is the operation handle 462 in FIG. 2 has been described in the above embodiment, the present invention is not limited to this. For example, when a projection that protrudes or retracts in the vicinity of the supply port 453 is provided and the on-off valve 461 is open, the projection projects to obstruct the attachment of the maintenance hose 32 to the supply port 453, while the on-off valve 461. When the is closed, the protrusion may be retracted so as to permit the attachment of the maintenance hose 32 to the supply port 453.

(About mounting control means (2))
Further, in the above embodiment, the case where the operation handle 462 of FIG. 2 is moved to the interference position or the non-interference position to inhibit or permit the attachment of the maintenance hose 32 to the supply port 453 has been described. Not limited to this. For example, the handle handle 462a of the operation handle 462 is configured to be used also as a joint of the supply port 453 and the maintenance hose 32, and the handle handle 462a is used only when the on-off valve 461 is closed. The maintenance hose 32 may be configured not to be attached to the supply port 453 unless the handle handle 462a as a joint is used. In such a configuration, when the on-off valve 461 is open, the handle handle 462a cannot be removed from the handle shaft 462b, so that the attachment of the maintenance hose 32 to the supply port 453 is hindered. On the other hand, when the on-off valve 461 is closed, the handle handle 462a can be detached from the handle shaft 462b and used as a joint, so that the attachment of the maintenance hose 32 to the supply port 453 is permitted. Become.

(About automatic control)
In the above embodiment, the case where the on-off valve 461 and the operation handle 462 in FIG. 2 are manually operated has been described. However, these devices may be automatically controlled, for example. For example, the on-off valve 461 is configured as an electromagnetic valve, the operation handle 462 is configured to be movable by an actuator, and a control computer is provided in the fire prevention system 100 of FIG. You may comprise so that opening and closing and the movement of the operation handle 462 may be controlled. Specifically, when the control computer opens the on-off valve 461 and moves the operation handle 462 to the interference position and receives a maintenance request from the user as an initial state before performing the maintenance operation, the on-off valve 461 may be closed and the operation handle 462 may be moved to the non-interference position.

(About alarm (1))
Moreover, in the said embodiment, you may provide an open / close state detection sensor, an attachment state detection sensor, and an alarm device with respect to the fire system 100 of FIG. The open / closed state detection sensor is a detection means for detecting the open / closed state of the open / close valve 461 in FIG. 2, and specifically detects whether the open / close valve 461 is open or closed. Any sensor that can be realized by using a valve sensor or the like or a known sensor other than the valve sensor can be used. The attachment state detection sensor is detection means for detecting the attachment state of the maintenance hose 32 with respect to the supply port 453. Specifically, it detects whether or not the maintenance hose 32 is attached to the supply port 453. For example, a known switch sensor or the like provided inside the supply port 453, or any sensor that can be realized using a known sensor other than the switch sensor can be used. The alarm device is an alarm means for performing an alarm based on the detection result of the open / closed state detection sensor or the detection result of the mounting state detection sensor. Specifically, the alarm device is configured to detect both detection results or only one detection result. For example, a display device such as a small liquid crystal display that displays image information, a speaker that outputs audio information, or the like can be used. The display device and the speaker can be provided at any place as long as the alarm can be notified to the user. For example, the supply unit 45 and the opening / closing unit 46 in the fire extinguishing pipe 11 shown in FIG. It may be provided between them.

  After being configured in this way, a control computer may be provided for the fire system 100 of FIG. 1, and the control computer may obtain a detection result of each sensor and issue an alarm.

  Specifically, the control computer detects, as a detection result of each sensor, a detection result (hereinafter, “first detection result”) indicating that the on-off valve 461 is closed and the maintenance hose 32 is attached. Or a detection result (hereinafter referred to as “second detection result”) indicating that the on-off valve 461 is closed and the maintenance hose 32 is not attached, or the on-off valve 461 is There is a possibility that a detection result (hereinafter referred to as “third detection result”) indicating that the maintenance hose 32 is not attached is acquired. Since the operation handle 462 in FIG. 2 functions as the attachment control means, the detection result indicating that the on-off valve 461 is open and the maintenance hose 32 is attached is not acquired.

  When the control computer acquires the first detection result, the control computer notifies the alarm device of an image or sound indicating that the maintenance is being performed as an alarm in order to notify the possibility of the maintenance being performed. It may be output. In addition, when the control computer acquires the second detection result, an image or sound indicating that the on-off valve 461 is closed in order to notify the possibility that the on-off valve 461 has been forgotten to be opened after the maintenance is completed, You may make it output to an alarm device as an alarm. Further, when the control computer obtains the third detection result, an image or sound indicating the standby state is used as an alarm in order to notify that the maintenance is not performed and the standby state is normal. You may comprise so that an alarm device may output.

(About alarm (2))
In the above “(about alarm (1))”, an LED or the like may be used as an alarm device.

  In such a configuration, for example, an alarm regarding maintenance can be performed by performing an alarm based on the detection result of the open / close state of the on-off valve 461 and the attachment state of the maintenance hose 32 to the supply port 453. The maintenance state can be notified to the worker. In particular, for example, when the on-off valve 461 is closed and the maintenance hose 32 is not attached to the supply port 453, there is a possibility that the on-off valve 461 has been forgotten to be opened even though the maintenance is completed. This can be notified, and human errors related to maintenance can be prevented.

(About supply control (1))
Moreover, in the said embodiment, you may provide a maintenance storage box and a supply control valve with respect to the fire system 100 of FIG. The maintenance storage box is a storage means for storing the maintenance hose 32, and specifically, a hollow portion in which the maintenance hose 32 is stored when maintenance is not performed. For example, it is provided in the vicinity of the floor slab storage box 102 and includes an accommodation detection sensor for detecting whether or not the maintenance hose 32 is accommodated. The supply control valve is a downstream side of the simultaneous opening valve 23 in the fire-extinguishing pipe 11 when the maintenance hose 32 is not accommodated by the maintenance storage box and the underground fire hydrant valve 22 is operated by the user. When the maintenance hose 32 is accommodated in the maintenance storage box and the underground fire hydrant valve 22 is operated by the user, the downstream of the simultaneous release valve 23 in the fire extinguishing pipe 11 is enabled. For example, a solenoid valve provided in series with the underground fire hydrant valve 22 between the upstream control pipe 12 and the downstream control pipe 13. Can be configured.

  After configuring in this way, a control computer may be provided for the fire system 100 of FIG. 1, and the control computer may acquire the detection result of the accommodation detection sensor and control the supply control valve.

  Specifically, the control computer closes the supply control valve when acquiring a detection result indicating that the maintenance hose 32 is stored as a detection result of the storage detection sensor. In this case, even if the underground fire hydrant valve 22 is opened after the pump 42 is started, the supply control valve provided in series with the underground fire hydrant valve 22 closes the flow path. Since the simultaneous open valve 23 remains closed without being able to supply the water, it becomes impossible to start the supply of water to the downstream side of the simultaneous open valve 23 in the fire extinguishing pipe 11.

  On the other hand, when the control computer obtains a detection result indicating that the maintenance hose 32 is not accommodated as the detection result of the accommodation detection sensor, the control computer opens the supply control valve. In this case, when the underground fire hydrant valve 22 is opened after the pump 42 is started, the supply control valve provided in series with the underground fire hydrant valve 22 opens the flow path. Since the simultaneous opening valve 23 is supplied, the supply of water to the downstream side of the simultaneous opening valve 23 in the fire extinguishing pipe 11 can be started.

  When configured in this way, when the maintenance hose 32 is not accommodated in the maintenance storage box, when the underground fire hydrant valve 22 is operated by the user, the downstream side of the simultaneous opening valve 23 in the fire-extinguishing pipe 11. In the case where the maintenance hose 32 is accommodated in the maintenance storage box and the underground fire hydrant valve 22 is operated by the user, the downstream of the simultaneous release valve 23 in the fire extinguishing pipe 11 is enabled. By making it impossible to start the supply of water to the side, for example, preparation for use of the maintenance hose 32 to perform maintenance (for example, taking out the maintenance hose 32 from the maintenance storage box and attaching it to the supply port 453, etc.) In spite of not being able to do it all at once in the fire extinguishing pipe Since it is possible to prevent the supply of water to the downstream side of 23, it is possible to prevent the simultaneous opening valve 23 in the fire-extinguishing pipe 11 from downstream when it is appropriate to prepare the use of the maintenance hose 32. Water supply can be started and proper maintenance can be performed.

(About supply control (2))
Further, with respect to the above “(about supply control (1))”, a pump activation device is provided together with or instead of the supply control valve, and the pump activation device acquires the detection result of the accommodation detection sensor. In addition, the start of the pump 42 may be controlled after receiving a start signal from a pump start switch (not shown) for starting the pump 42 of FIG. 1 described above. Specifically, when the pump activation device receives the activation signal from the pump activation switch, the pump activation device does not activate the pump 42 when acquiring the detection result indicating that the maintenance hose 32 is accommodated. The pump 42 may be activated when a detection result indicating that the maintenance hose 32 is not accommodated is acquired. In this case, the pump activation device corresponds to “supply control means”, and the pump activation switch corresponds to “operation means”.

(About fire extinguishing device accommodation means)
Moreover, although the said embodiment demonstrated the case where the above-mentioned underground side accommodation apparatus group was accommodated in the floor slab storage box 102 of FIG. 1, it is not restricted to this. For example, you may accommodate all or one part of the underground side accommodation apparatus group in the extinguishing apparatus accommodation means. Here, the “fire extinguishing device accommodating means” is a fire extinguishing device accommodating means for accommodating a fire extinguishing device, and specifically, at least a part of the fire extinguishing device accommodating means is only a frame that surrounds the fire extinguishing device. It is comprised by. Further, the “fire extinguishing device” is a device for outputting a fire extinguishing liquid, for example, a device or a component for supplying the fire extinguishing liquid to the fire hose 31, It is a concept including an included device or component. FIG. 10 is a perspective view of the fire extinguishing device accommodating portion, and FIG. 11 is a front view of the fire extinguishing device accommodating portion in a state where the underground side accommodated device group is accommodated. In addition, in the fire extinguishing device accommodating portion 600, all of the underground side accommodated device groups are actually accommodated, but in FIG. 11, for convenience of explanation, the underground side fire hydrant valve 22, the automatic pressure regulating valve 24, and the foam The tank 43 and the eductor 44 are illustrated as rectangles for convenience of explanation. A system including the “fire extinguishing device accommodating portion 600” and the “underground side accommodated device group” corresponds to the “fire extinguishing system”.

  In the following description, the X1-Y1-Z1 directions shown in FIG. 10 are directions orthogonal to each other. Specifically, for example, the + Z1 direction is referred to as the upper side, and the −Z1 direction is referred to as the upper side. The Z1 direction is referred to as the lower side, the X1 direction is the left-right direction, for example, the + X1 direction is referred to as the right side, the -X1 direction is referred to as the left side, and the Y1 direction is the front-rear direction. The front side is referred to and the −Y1 direction is referred to as the back side (the same applies to the XZ direction in FIG. 11).

  The fire extinguishing device accommodating portion 600 shown in FIGS. 10 and 11 is a fire extinguishing device accommodating means for accommodating the underground side accommodated device group, for example, separate from the fire hydrant storage box 101 of FIG. The evacuation passage below the floor slab 900 in FIG. 1 is provided on the underground side. The specific type and configuration of the fire extinguishing device accommodating portion 600 is arbitrary.
