Description

[Technical Field]

[0001] The present invention relates to an evacuation guidance system to be installed in an evacuation passage. [Background technology]

[0002] Conventionally, fire hydrant systems have been installed as disaster prevention devices in tunnels such as expressways and motorways, and these systems house fire hydrant equipment such as fire hoses and hydrant valves, as well as fire extinguishers, in order to respond to emergencies such as fires that occur inside the tunnel. Furthermore, fire hydrant systems are generally installed by embedding them into the tunnel walls along the length of the tunnel, for example, at intervals of 50 meters, where observer passages are provided, by cutting out boxes from the walls, or by hanging them from the tunnel walls without cutting out boxes from the walls, or by installing them on the road surface of the observer passages (Patent Documents 1-3).

[0003] In addition, if a fire breaks out inside a tunnel due to a vehicle accident or breakdown, not only will the fire be dealt with using the fire hydrant equipment, but road users will also be required to evacuate through the guard passage, which serves as an evacuation route, to the tunnel entrance or exit or to the emergency exit that leads to the evacuation shaft. [Prior art documents] [Patent documents]

[0005] However, in the event of a fire in which fuel such as gasoline ignites and rapid combustion occurs, a large amount of black smoke is generated and spreads throughout the tunnel, forcing evacuees to evacuate in conditions where visibility is poor due to the spread of black smoke. This means that they are unable to identify their current location or the location of the emergency exit located along the guard passage, and it takes time to reach the emergency exit. In the worst case scenario, they may not be able to reach the emergency exit and be left behind in the tunnel.

[0027] (Evacuation guidance system in tunnels) The evacuation route is a guard passageway set up along the tunnel wall inside the tunnel. The disaster prevention devices are installed at predetermined intervals along the tunnel wall on the road surface of the guard passage. [Effects of the Invention]

[0028] (Effectiveness of evacuation guidance system) The present invention is an evacuation guidance system that includes disaster prevention devices installed at predetermined intervals along the walls of the evacuation passage, and cord-like members that are stretched between adjacent disaster prevention devices and that guide people to an evacuation destination. Therefore, even in a situation where visibility is poor, such as when smoke has spread inside a tunnel, quick and reliable evacuation is possible by following the cord-like members that are stretched between the disaster prevention devices installed at predetermined intervals along the walls of the evacuation passage.

[0029] (Effect of Method 1 for stretching cable-like members) Furthermore, since the cord-like members are fixedly stretched between adjacent disaster prevention devices, it is possible to construct an evacuation guidance system at low cost even when the evacuation route is long.

[0030] (Effect of Method 2 for stretching cable-like members) In addition, the rope-like member is stretched in a loop shape that can be moved around between adjacent disaster prevention devices, so by looping the rope-like member, the evacuation direction can be tactilely communicated to evacuees who grasp the rope-like member, allowing for faster and more reliable evacuation even in situations where visibility is poor due to smoke, etc.

[0031] (Effect of the light-emitting part of the cord-like member) Furthermore, the rope-like members are provided with light-emitting parts that emit light electrically, so that even in situations where visibility is poor due to smoke or the like, the light-emitting parts can inform the location of the rope-like members, making it possible for evacuees to use the rope-like members more reliably.

[0032] (Effect of the light-emitting part of the cord-like member and the lighting device) Furthermore, the cord-like member is equipped with a light-emitting portion that emits light when irradiated with light, and a lighting device that illuminates the light-emitting portion with a predetermined light is arranged corresponding to the position of the light-emitting portion, so that even in situations where visibility is poor due to smoke, etc., the position of the cord-like member can be notified by the emitting portion, making it possible for evacuees to use the cord-like member more reliably. Furthermore, since it does not emit light using electricity like the light-emitting portion described above, no signal line for supplying electricity is required, and even a cord-like member that moves in a circular motion can be made to emit light.

[0033] (Effect of support members for cord-like members) In addition, since the support members that support the stretched rope-like members from below are arranged between adjacent disaster prevention devices, it is possible to stretch the rope-like members between adjacent disaster prevention devices without them sagging, even if the distance between the devices is long, for example, 50 meters.

[0034] (Effect of direction indicator) In addition, the disaster prevention device is equipped with a direction indicator that shows the evacuation direction, so that the evacuation direction can be confirmed when passing in front of the disaster prevention device, allowing for more reliable and rapid evacuation.

[0035] (Effect of displaying evacuation directions) In addition, the direction indicator displays the direction away from the fire site or the direction toward an evacuation exit located at a predetermined position on the evacuation route as the evacuation direction, making it possible to guide evacuees to an appropriate evacuation site depending on their location.

[0036] (Sound equipment effects) The disaster prevention device is also equipped with an audio device that outputs a predetermined guidance message, and the audio device is arranged so that it has directivity toward at least the adjacent disaster prevention device, so that information about evacuation can be conveyed auditorily to evacuees who are evacuating by following the rope-like member, enabling more reliable and rapid evacuation. Furthermore, because the audio device is arranged so that its directivity is toward the evacuees who are evacuating by following the rope-like member, it is suppressed and prevented that evacuees miss the guidance message.

[0037] (Sound device voice message effect) In addition, the guidance messages include guidance messages encouraging evacuees who have reached the disaster prevention device by a rope-like member to move to the next rope-like member leading to the evacuation destination, and guidance messages encouraging evacuees who have reached the disaster prevention device by a rope-like member to move to an evacuation exit located on the next rope-like member leading to the evacuation destination.This allows evacuees to know the next evacuation action from the guidance messages, making it possible to evacuate more quickly and reliably.

[0038] (Effect of orbital drive mechanism 1) In addition, the circular drive mechanism that moves the rope-like member in a circular motion between adjacent disaster prevention devices includes a drive roller that is arranged on one of the adjacent disaster prevention devices and that rotates the rope-like member, a plurality of guide rollers that are arranged at predetermined positions between the adjacent disaster prevention devices, and a motor that drives the drive roller.The rope-like member is stretched in a loop between the adjacent disaster prevention devices via the drive roller and the plurality of guide rollers, so that the rope-like member can be rotated in a direction that encourages evacuation in each of the adjacent disaster prevention devices independently, allowing for faster and more reliable evacuation.

[0039] (Effect of orbital drive mechanism 2) The rope-like member is composed of a first rope-like member and a second rope-like member, the first rope-like member being stretched in a loop between one of the adjacent disaster prevention devices and a predetermined intermediate position between the adjacent disaster prevention devices, and the second rope-like member being stretched in a loop between the other of the adjacent disaster prevention devices and the intermediate position, and the circular drive mechanism for circularly moving the first rope-like member includes a first drive roller arranged on one of the adjacent disaster prevention devices and for circularly moving the first rope-like member, a plurality of first guide rollers arranged at predetermined positions between one of the adjacent disaster prevention devices and the intermediate position, and a first motor for driving the first drive roller, and the first rope-like member being stretched in a loop between one of the adjacent disaster prevention devices and the intermediate position via the first drive roller and the plurality of first guide rollers, and the circular drive mechanism for circularly moving the second rope-like member includes a first drive roller arranged on one of the adjacent disaster prevention devices and for circularly moving the first rope-like member, a plurality of first guide rollers arranged at predetermined positions between one of the adjacent disaster prevention devices and the intermediate position, and a first motor for driving the first drive roller, The device is equipped with a second drive roller that is arranged on the other side of the adjacent disaster prevention device and that rotates the second rope-like member, a plurality of second guide rollers that are arranged at predetermined positions between the other side of the adjacent disaster prevention device and an intermediate position, and a second motor that drives the second drive roller, and the second rope-like member is stretched in a loop between the other side of the adjacent disaster prevention device and the intermediate position via the second drive roller and the plurality of second guide rollers.Therefore, for example, if there is an emergency exit between adjacent disaster prevention devices, the evacuation directions will be opposite when heading toward the emergency exit from one of the adjacent disaster prevention devices and when heading toward the emergency exit from the other side of the adjacent disaster prevention equipment, but since the first rope-like member and the second rope-like member can be rotated independently, it is possible to guide evacuees toward the emergency exit from either of the adjacent disaster prevention devices.

[0040] (Effect of lap speed on walking speed) In addition, the rope-like members are designed to rotate at a predetermined speed corresponding to the walking speed of the evacuees. To guide an evacuee comfortably at a walking speed similar to that of the evacuee, to safely guide the evacuee at a walking speed slower than that of the evacuee, and to enable the evacuee to evacuate quickly at a walking speed faster than that of the evacuee.

[0041] (Effect of the position of the bottom and top loops of the cord-like member) Furthermore, the rope-like members are positioned so that the lower part of the looped rope member is at a predetermined height that can be held by evacuees, and the upper part of the looped rope member is at a predetermined height that cannot be held by evacuees, or so that the upper part of the looped rope member is positioned closer to the wall of the evacuation passage than the lower part of the looped rope member.This means that evacuees will grab the lower part of the looped rope member and will not grab the upper part of the looped rope member, which is moving in the opposite direction to the lower part of the looped rope member, allowing for faster and more reliable evacuation without impeding the evacuation of evacuees.

[0042] (Effect of the circumferential direction of the cord-like member) In addition, the rope-like member is designed to rotate so that the lower part of the rope-like member moves in a direction away from the location of the fire or in a direction toward an evacuation exit provided at a predetermined position in the evacuation passage, making it possible to guide evacuees to an appropriate evacuation location depending on their location.

[0043] (Effects of the fire hydrant itself and the evacuation guidance unit) In addition, the disaster prevention device is a fire hydrant device, which comprises a fire hydrant main body that houses at least specified fire hydrant equipment, and an evacuation guidance unit that is positioned at least on the side of the fire hydrant device located next to the fire hydrant main body and houses specified equipment used for evacuation, and a cord-like member is stretched between the evacuation guidance units of adjacent fire hydrant devices, making it possible to simply and easily construct an evacuation guidance system by adding an evacuation guidance unit to a fire hydrant device that has previously been installed as a disaster prevention device.

[0044] (Effects of portable respirators) In addition, the evacuation guidance unit is designed to store a portable respirator as a designated piece of equipment used for evacuation, allowing it to be freely removed, so oxygen can be secured using the portable respirator, enabling safe evacuation.

[0045] (Effect of guide rope) In addition, the cord-like member is a guide rope that has heat resistance and little friction resistance, so it can be done at low cost and enables evacuees to evacuate safely without injuring their hands when they grasp the cord-like member.

[0047] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an evacuation guidance system according to the present invention will be described below with reference to the accompanying drawings. However, the present invention is not limited to the following embodiment.

[0048] [Basic concept of the embodiment] First, the basic concept of the embodiment will be described. The embodiment generally relates to an evacuation guidance system constructed in an evacuation passage, and the concept includes evacuation guidance equipment. Note that the "evacuation passage" does not have to be a passage exclusively used for evacuation, but may be a passage that is also used for other purposes such as normal times or inspections, and includes, for example, a guard passage in a tunnel or a corridor in a building.

[0049] Here, the "evacuation guidance system" is a system that guides evacuation so that people can evacuate to a safe place when an abnormality such as a fire occurs, and is equipped with, for example, the devices, equipment, instruments, device control means, etc. necessary for evacuation guidance. The location where the evacuation guidance system is installed is arbitrary, but it can be installed in, for example, a tunnel with a guard passageway along the tunnel wall or a facility with a long corridor, and in the description of the embodiment, the evacuation guidance system installed in the guard passageway in a tunnel will be described as the subject.

[0050] The evacuation guidance system of this embodiment is characterized by comprising "disaster prevention devices" installed at predetermined intervals along the walls of the evacuation passage, and "cord-like members" stretched between adjacent disaster prevention devices to guide people to the evacuation destination.

[0051] Furthermore, "disaster prevention devices" are devices for protection against abnormalities such as fires, and include "fire hydrant devices" installed in tunnels on expressways and motorways. Furthermore, a "fire hydrant device" is a device that includes a hydrant body that houses at least fire hoses and valves, and may also include electrical equipment such as red indicator lights and transmitters, as well as fire extinguishers, and is a concept that includes fire hydrant facilities in which fire hydrant devices are installed.

[0052] Furthermore, a "cord-like member" is a rope-like member that evacuees can grasp and follow to move towards their evacuation destination, and the material and type thereof are optional, but in consideration of cost and the safety of evacuees, it includes a guide rope that is heat resistant and has low friction resistance.

[0053] Therefore, even in situations where visibility is poor due to smoke or the like, quick and reliable evacuation is possible by following the cord-like member.

[0054] Furthermore, the evacuation guidance system of the embodiment is divided into two embodiments depending on the method of stretching the rope-like members. In the "first embodiment of the evacuation guidance system," the rope-like members are stretched fixedly between adjacent disaster prevention devices, and in the "second embodiment of the evacuation guidance system," the rope-like members are stretched in a loop shape that can move in a circular motion between adjacent disaster prevention devices. Because the rope-like members can move in a circular motion, it is possible to tactilely convey the evacuation direction to evacuees who grab the rope-like members and guide them to their evacuation destination.

[0055] Furthermore, the cord-like member is provided with a "light-emitting portion that emits light by electricity" or a "light-emitting portion that emits light by irradiation with light" so that evacuees can easily recognize the cord-like member in situations where visibility is poor due to smoke, etc. The area on the cord-like member where the "light-emitting portion" is arranged is arbitrary, and as long as it helps evacuees to recognize the cord-like member, the light-emitting portion may be arranged over the entire cord-like member, a partial area, or multiple areas.

[0056] The "electrically emitting light-emitting unit" can be realized, for example, by wrapping a known LED tape, which is a flexible tape with LEDs arranged at predetermined intervals, around a cord-like member. The light-emitting unit can be illuminated in any form, but blinking can improve visibility. Furthermore, a cord-like member equipped with an electrically emitting light-emitting unit serves as a signal line for supplying electricity to the light-emitting unit, and since the signal line limits the circular movement of the cord-like member, this system is not applicable to the "second embodiment of the evacuation guidance system" but is applicable to the "first embodiment of the evacuation guidance system."

[0057] The "light-emitting unit that emits light when irradiated with light" includes a "fluorescent unit" that emits light while irradiated with light and a "luminous unit" that stores the light energy of the irradiated light and emits light using the stored light energy even when the light irradiation stops. For example, this can be achieved by wrapping fluorescent tape coated with a predetermined color of fluorescent paint around the cord-like member, making it easily visible even in situations where visibility is impaired by smoke or other factors. When the cord-like member includes a light-emitting unit that emits light when irradiated with light, the evacuation guidance system also includes a "lighting device" for irradiating the light-emitting unit. The color of the light emitted by the "fluorescent unit" or "luminous unit" is arbitrary, but yellow is preferable, as the order of visibility is best: yellow, yellow-red, yellow-green, green, red, and blue. Furthermore, a cord-like member equipped with a light-emitting unit that emits light when irradiated with light does not require a signal line like an electrically irradiated light-emitting unit. The light-emitting unit is illuminated by light irradiated from a lighting device installed separately from the cord-like member, and therefore can be applied to both the "first embodiment of the evacuation guidance system" and the "second embodiment of the evacuation guidance system."

[0058] The evacuation guidance system also includes a "support member" that supports the rope-like member from below, preventing the rope-like member stretched between adjacent disaster prevention devices from sagging and making it easier for evacuees to follow the rope-like member. The structure and type of support member are optional, but one example is a hanging ring, through which the rope-like member is passed and stretched, thereby supporting the rope-like member stretched over the hanging ring from below.

[0059] The disaster prevention device is also equipped with a "direction indicator" that indicates the evacuation direction, for example, away from the location of the fire or toward an evacuation exit located at a predetermined position in the evacuation passage. This is because, although it is desirable to evacuate in a direction away from the location of the fire, in the case of a disaster prevention device where the location of the fire is far away and an evacuation exit located in the evacuation passage is close, it may be possible to evacuate more quickly by guiding people toward the evacuation exit even if it is in a direction closer to the location of the fire. In addition, the evacuation direction may be indicated taking into account the direction of air currents, etc.

[0060] The disaster prevention device is also equipped with an "audio device" that outputs predetermined guidance messages, and the guidance messages include, for example, guidance messages encouraging evacuees who have reached the disaster prevention device by a rope-like member to move to the next rope-like member leading to their evacuation destination, and guidance messages encouraging evacuees who have reached the disaster prevention device by a rope-like member to move to an evacuation exit located halfway along the next rope-like member leading to their evacuation destination.

[0061] Furthermore, the "audio device" is positioned at least on the side of the disaster prevention device next to the disaster prevention device so that it has directivity toward the adjacent disaster prevention device, making it easier for evacuees following the rope-like member to hear the guidance message. Here, "neighboring disaster prevention device side" refers to two locations on either side of the disaster prevention device, since disaster prevention devices installed at a predetermined interval generally have disaster prevention devices on both sides. However, for disaster prevention devices located at the very end, only one disaster prevention device is installed on one side, so only one location on that side is targeted. Note that even for disaster prevention devices that only have one disaster prevention device on one side, for purposes such as commonality of disaster prevention devices, it is not prohibited to provide two audio devices on either side of the disaster prevention device. Furthermore, different voices of guidance messages may be alternated for each disaster prevention device, for example, a male voice message and a female voice message, so that evacuees can audibly know when they have reached the next point on the rope-like member.

[0062] In addition, the "second embodiment of the evacuation guidance system" is provided with a "circular drive mechanism" that moves the rope-like member in a circular motion. The "circular drive mechanism" includes, for example, a "drive roller" that moves the rope-like member in a circular motion, a plurality of "guide rollers," and a "motor" that drives the drive roller, and the rope-like member is stretched in a loop between adjacent disaster prevention devices by passing through the drive roller and the plurality of guide rollers.

[0063] In addition, in the "second embodiment of the evacuation guidance system," the rope-like member may be composed of separate first and second rope-like members, with the first rope-like member stretched in a loop between one of the adjacent disaster prevention devices and a predetermined intermediate position between the adjacent disaster prevention devices, and the second rope-like member stretched in a loop between the other of the adjacent disaster prevention devices and a predetermined intermediate position, and each of the first and second rope-like members may be provided with a circular drive mechanism. Here, the location indicated by the "predetermined intermediate position between the adjacent disaster prevention devices" refers to a space having a certain extent; that is, there may be a gap between the stretched first and second rope-like members. Also, the location is not necessarily limited to the midpoint between the adjacent disaster prevention devices, and the stretched distance of the first and second rope-like members may differ.

[0064] By configuring the rope-like member as a separate first rope-like member and a second rope-like member, each equipped with an independent circular drive mechanism, for example, if there is an emergency exit between adjacent disaster prevention devices, the rope-like member can guide evacuees to the appropriate emergency exit from either side of the disaster prevention device.

[0065] Furthermore, the rotation speed of the cord-like member is arbitrary, and can be set to the same speed as the walking speed of the evacuees if a natural guide is required, a speed slower than the walking speed of the evacuees if safety is prioritized, or a speed faster than the walking speed of the evacuees if speedy evacuation is prioritized.

[0066] Furthermore, the "rope-like member" is positioned so that the lower part of the looped rope member is at a predetermined height that evacuees can hold, and the upper part of the looped rope member is at a predetermined height that evacuees cannot hold, or so that the upper part of the looped rope member is positioned closer to the wall of the evacuation passage than the lower part of the looped rope member. This allows evacuees to use only the lower part of the upper and lower parts of the rope member, which move in opposite directions, and allows the lower part of the rope member to move in a direction away from the location of the fire or in a direction toward an evacuation exit located at a predetermined position in the evacuation passage, thereby achieving a quick and reliable evacuation.

[0067] Furthermore, when the disaster prevention device is a fire hydrant device, the "fire hydrant device" comprises at least a "fire hydrant main body" that houses specified fire hydrant equipment in order to function as a fire hydrant device, and at least an "evacuation guidance unit" that is placed on the fire hydrant device side located next to the fire hydrant main body and houses specified equipment used for evacuation in order to function as a disaster prevention device of an evacuation guidance system, and a rope-like member is stretched between the evacuation guidance units of adjacent fire hydrant devices.

[0068] The specific equipment used for evacuation stored in the evacuation guidance unit is arbitrary, but for example, a "portable respirator" is stored so that it can be removed freely.

[0069] Furthermore, the terms "provide," "place," "install," and "store" can encompass other terms that can be substituted for each term, and are concepts that can include terms that can be substituted for each term based on their meaning, such as "attach," "attach and fix," and "mount."

[0070] Specific embodiments will be described below. In the specific embodiments shown below, the "disaster prevention device" is a "fire hydrant device," the "fire hydrant device" is installed on the road surface of a guard passageway provided along the tunnel wall inside a tunnel, the "cord-like member" is a "guide rope," the "support member" is a "hanging ring," the "audio device" is a "speaker," and the "light-emitting unit that emits light when irradiated with light" is a "fluorescent unit," and the descriptions will be divided into a "first embodiment of an evacuation guidance system" and a "second embodiment of an evacuation guidance system."

[0072] [a. First embodiment of evacuation guidance system] First, a first embodiment of an evacuation guidance system will be described. In this description, reference will be made to Fig. 1, which shows the first embodiment of the evacuation guidance system. Fig. 1(A) shows the configuration of the evacuation guidance system, Fig. 1(B) shows a portion of the guide rope, and Fig. 1(C) shows the circuit configuration of the LED tape provided on the guide rope.

[0073] 1(A), the X, Y, and Z directions are perpendicular to each other. Specifically, when looking at the front of the fire hydrant device 10, the X direction is the left-right direction, the Y direction is the up-down direction, and the Z direction is the front-to-back direction. The +X side of the X direction is the right side, the -X side is the left side, the +Y side of the Y direction is the top side, the -Y side is the bottom side, and the +Z side of the Z direction is the front side, and the -Z side is the rear side. This also applies to FIGS. 2 to 9, 11 to 14, and 16, which are embodiments of the present invention.

[0074] As shown in Figure 1(A), a guard passage 28, whose surface is at a predetermined height relative to the surface of a road 26, is installed along the tunnel wall inside the tunnel, and fire hydrant devices are installed at predetermined intervals on the surface of the guard passage 28, for example, at 50-meter intervals, such as fire hydrant devices 10 (10-1) and 10 (10-2). Taking fire hydrant device 10 (10-1) as an example, fire hydrant device 10 (10-1) is composed of, for example, a fire hydrant unit 12, a hose storage unit 14, and evacuation guidance units 16 and 17, and the hydrant itself is composed of the fire hydrant unit 12 and the hose storage unit 14.

[0075] The fire hydrant unit 12 includes fire hydrant equipment including a water discharge nozzle and a fire hydrant valve (excluding the fire hose), a fire extinguisher, and electrical equipment such as a red indicator light and a transmitter.

[0076] The hose storage unit 14 stores a fire hose (shape-retaining hose) of a predetermined length, for example, about 30 meters, and the tip of the fire hose is pulled into the fire hydrant unit 12 and connected to a water discharge nozzle. The hose storage unit 14 also functions as a stand for installing the fire hydrant unit 12 at a predetermined height above the road surface of the guard passage 28.

[0077] The evacuation guidance units 16, 17 are installed on both the left and right sides of the hydrant unit 12 and hose storage unit 14, which are arranged in the vertical direction (height direction), and a guide rope 18 is stretched between the evacuation guidance units of adjacent fire hydrant devices, for example, as shown in Figure 1(A), between the evacuation guidance unit 16 of the fire hydrant device 10 (10-1) and the evacuation guidance unit 17 of the fire hydrant device 10 (10-2). In addition, the evacuation guidance units 16, 17 are equipped with speakers 22a, 22b, which output guidance messages regarding evacuation guidance.

[0078] The guide rope 18 has a predetermined rope diameter, for example, a thickness of about 10 mm to 15 mm, that allows evacuees to move while holding the guide rope 18. Furthermore, the guide rope 18 is a soft rope made by twisting together wires made of, for example, fiber or resin, and allows evacuees to move while following the rope without injuring their hands.

[0079] Furthermore, since the guide rope 18 must be stretched across the approximately 50-meter distance between the evacuation guidance units of adjacent fire hydrant devices without sagging, it is strung through hanging rings 20 placed at specified intervals at a specified height on the tunnel wall. Since evacuees will have to let go of the guide rope 18 at the hanging ring 20 and then grab it again, the hanging ring 20 may be shaped like a C with a portion of the front open, allowing evacuees to evacuate without letting go of the guide rope 18.

[0080] Here, the height of the stretched guide rope 18 from the road surface of the guard passage 28 is set to a height that can be easily grasped by the hand of an evacuee moving along the guard passage 28, and this height is set to 100 cm, for example, from the range of 80 to 120 cm, which is the expected height from the road surface of the guard passage 28 to the height from the waist to the chest of an evacuee.

[0081] Furthermore, the guide rope 18 is provided with light-emitting elements that emit light electrically at predetermined intervals, so that the guide rope 18 can be seen as much as possible even in situations where evacuees cannot see, such as when smoke from a fire inside the tunnel spreads. The configuration and type of the light-emitting elements provided on the guide rope 18 are arbitrary, but for example, as shown in Fig. 1(B), an LED tape 30 equipped with LEDs 32 as light-emitting elements is wrapped and fixed around the guide rope 18.

[0082] A known LED tape 18 can be used, and as shown in Figure 1(C), LEDs 32 are connected in parallel at a predetermined interval to a positive signal line 34a and a negative signal line 34b between insulating flexible tapes, and in the event of a fire inside the tunnel, a predetermined drive voltage is applied between the signal lines 34a and 34b to drive the LEDs 32 to emit light.

[0083] Here, the intervals between the LEDs 32 provided on the guide rope 18 can be arbitrary, and if the intervals are set to, for example, 1 to 2 meters so that evacuees can ascertain the position of the stretched guide rope 18 by the light emitted by the LEDs 32, then the number of LEDs 32 provided on one guide rope 18 will be approximately 25 to 50. Furthermore, since the drive current increases when a large number of LEDs 32 are provided on the guide rope 18, the LED tape 30 provided on one guide rope 18 may be divided, for example, in half, and a drive voltage may be applied to each LED tape 30 via separate signal lines 34a, 34b.

[0084] [b. Fire hydrant system structure] Next, the structure of the fire hydrant device will be described using the fire hydrant device 10 (10-1) as an example. In this description, reference will be made to Fig. 2, which shows the fire hydrant device of the first embodiment from the front (front), and Fig. 3, which shows the housing structure of the fire hydrant device of Fig. 2 in an assembled and disassembled state.

[0085] As shown in Fig. 2, the fire hydrant device 10 (10-1) is installed on a stand 55 installed on the road surface of the guard passage 28, and is composed of a fire hydrant unit 12, a hose storage unit 14, and evacuation guidance units 16 and 17. In addition, as shown in Fig. 3, the housing of the fire hydrant device 10 is divided into a first housing 60a, a second housing 60b, a third housing 60c, a fourth housing 60d, and a fifth housing 60e.

[0086] 3, the interior of the first housing 60a, which is a part of the housing of the hydrant unit 12, serves as a fire hydrant equipment storage section 96 that stores the hydrant equipment except for the fire hose. The interior of the second housing 60b, which is also a part of the housing of the hydrant unit 12, is divided into left and right sections by a partition wall 94, with the right section serving as an electrical equipment storage section 94a and the left section serving as a fire extinguisher storage section 94b. The interior of the third housing 60c, which is the housing of the hose storage unit 14, serves as a hose storage section 98 that stores the fire hose. Furthermore, the fourth housing 60d, which is the housing of the evacuation guidance unit 16, and the fifth housing 60e, which is the housing of the evacuation guidance unit 17, are vertically long (long in the vertical direction) housings with a height equal to the combined height of the third housing 60c and the first housing 60a (second housing 60b).

[0087] In addition, a hose outlet opening 88a is formed on the left side of the bottom surface (left side of the lower surface) of the first housing 60a, and a hose outlet opening 88b corresponding to the hose outlet opening 88a is formed on the upper surface of the third housing 60c, which is arranged below the first housing 60a.

[0088] In addition, a piping hole 90a is formed on the right side of the bottom surface of the first housing 60a, and piping holes 90b and 90c corresponding to the piping hole 90a are formed on the top and bottom surfaces of the third housing 60c, which is arranged below the first housing 60a.

[0089] In addition, a wire passage opening 92a is formed on the upper left side of the first housing 60a, and a wire passage opening 92b corresponding to the wire passage opening 92a is formed on the upper right side of the second housing 60b, which is arranged to the left of the first housing 60a.

[0090] As shown in Fig. 2, a decorative frame 62a is attached to the front of the first housing 60a. A fire hydrant door 64 is disposed below the door opening of the decorative frame 62a. When the lock is released by operating the door opening / closing handle 6410, the fire hydrant door 64 opens vertically (downward) about a hinge 64a to a position approximately perpendicular to the road surface of the guard passage 28. Note that "perpendicular" does not strictly mean perpendicular to the road surface of the guard passage, but includes being approximately perpendicular to the road surface of the guard passage, and the same applies to "parallel."

[0091] A maintenance door 65 that opens vertically (upward) around a hinge 65a is disposed above the door opening of the decorative frame 62a. The upward-opening maintenance door 65 can be held open by a stay (support rod) disposed inside the door.

[0092] The fire hydrant equipment storage section 96 inside the first housing 60a stores fire hydrant equipment including valves including a fire hydrant valve, a water discharge nozzle connected to a fire hose, and an operating lever for opening and closing the fire hydrant valve, as described below.

[0093] A decorative frame 62b is attached to the front of the second housing 60b. An electrical door 68 that opens sideways to the right on hinges 68a is disposed in the door opening on the right side of the decorative frame 62b, and an auxiliary door 70 that opens sideways to the left on hinges 70a is disposed on the left side of the electrical door 68 to allow access to the internal terminal boxes 75a, 75b.

[0094] The electrical door 68 is equipped with electrical equipment such as a red indicator light 72, a transmitter 74, and a response lamp 78, and a telephone jack 76 is located on the inside of the door. The red indicator light 72 is always lit, allowing the location of the fire hydrant device 10 (10-1) to be confirmed from a distance. When the transmitter 74 is pressed and switched on in the event of a fire or other incident, it transmits a transmission signal. A fire alarm is output from a disaster prevention receiving panel installed in an electrical room or the like that receives this signal, and the fire hydrant device 10 (10-1) receives a response signal from the disaster prevention receiving panel and causes the red indicator light 72 to flash and the response lamp 78 to light up.

[0095] A high-voltage terminal box 75a and a low-voltage terminal box 75b are arranged, for example, vertically side by side on the rear surface of the second housing 60b opposite the auxiliary door 70. The high-voltage terminal box 75a uses a built-in terminal block to connect a high-voltage cable drawn from outside the fire hydrant device 10 (10-1) to the red indicator light 72. The low-voltage terminal box 75b uses a built-in terminal block to connect a low-voltage cable drawn from outside the fire hydrant device 10 (10-1) to the transmitter 74, the response lamp 78, and the telephone jack 76.

[0096] Furthermore, a fire extinguisher door 66 is disposed in the door opening on the left side of the decorative frame 62b attached to the second housing 60b. The door opens to the left on hinges 66a when the lock is released by operating the door opening / closing handle 6610. Two fire extinguishers, for example, are stored in a fire extinguisher storage section 94b inside the door. The fire extinguisher door 66 is also provided with a viewing window 6612, which makes it possible to check from the outside whether a fire extinguisher is present.

[0097] The third housing 60c houses a fire hose within the housing, and also functions as a stand for mounting and fixing the first housing 60a and the second housing 60b, which are connected and fixed in the left-right direction, against or close to the tunnel wall at a predetermined height above the road surface of the guard passage 28.

[0098] A decorative frame 62c is attached to the front of the third housing 60c. A hose storage door 80 is disposed in the door opening of the decorative frame 62c. When the lock is released by operating a door opening / closing handle 8010, the hose storage door 80 opens vertically (downward) about a hinge 80a to a position approximately perpendicular to the road surface of the guard passage 28. The size of the door opening in which the hose storage door 80 is disposed is arbitrary, but it should be large enough to allow the fire hose to be rewound into the third housing 60c after using the fire hydrant device 10 (10-1). For example, the vertical width (width in the up-down direction) of the door opening is about half the vertical width of the front of the third housing 60c, and the horizontal width (width in the left-right direction) of the door opening is wide enough to allow the left and right inner sides of the hose storage section formed inside the third housing 60c to be reached from the outside.

[0099] A decorative frame 62d is attached to the front of the fourth housing 60d, and a decorative frame 62e is attached to the front of the fifth housing 60e, and a fixture door 86 that opens sideways to the right is disposed in the door opening of the decorative frames 62d and 62e when the door is unlocked by operating the door opening handle 8610. In addition, left direction indicators 82a and 82b and right direction indicators 84a and 84b that indicate the evacuation direction are disposed above the fixture doors 86 of the fourth housing 60d and the fifth housing 60d.

[0100] [c. Installation of fire hydrant equipment] Next, the installation of a fire hydrant device in a guard passage will be described using the fire hydrant device 10 (10-1) as an example. In this description, in addition to Fig. 2 and Fig. 3, Fig. 4, which shows the fire hydrant device in Fig. 2 from the left side, will be referenced. Note that in Fig. 4, the fourth housing 60d is omitted in order to show the heights of the first housing 60a to the third housing 60c.

[0101] As shown in Figure 4, below the cylindrical (circular cross section) tunnel body constructed by the shield tunneling method, a road 26 is constructed in the longitudinal direction (left-right direction) of the tunnel, and below a tunnel wall 35 that runs along the road 26, a monitor's passage 28, whose surface is located at a predetermined height relative to the surface of the road 26, and cables are laid along the tunnel wall 35, and a water supply pipe 27 branching off from the main water supply pipe 23 is taken out above the road surface of the monitor's passage 28. An inlet pipe is connected to the water supply pipe 27, and the inlet pipe passes vertically through a third housing 60c and is drawn into the interior of the first housing 60a, which is located above the third housing 60c.

[0102] Since it is difficult to cut out a box from the tunnel wall 35 constructed by the shield construction method to install the fire hydrant device 10 (10-1), the third housing 60c, the fourth housing 60d, and the fifth housing 60e are installed on a platform 55 on the road surface of the monitor's passage 28, close to the tunnel wall surface 35, and the connected first housing 60a and second housing 60b are attached and fixed on the third housing 60c, so that the first housing 60a and the second housing 60b are installed at a predetermined height above the road surface of the monitor's passage 28. In addition, the upper parts of the first housing 60a, the second housing 60b, the fourth housing 60d, and the fifth housing 60e are fixed to the tunnel wall surface 35 by housing support members 75 to prevent them from falling forward.

[0103] Here, the height of the third housing 60c is set so that the height from the road surface of the monitor passage 28 to all operation targets, including the transmitter 74 and water discharge nozzles arranged on the fire hydrant device 10 (10-1), falls within the legally defined appropriate operation range. If the road surface of the monitor passage 28 is the standing surface of road users, as is well known, the legally defined appropriate operation range has a lower limit height H1 from the road surface of 800 mm and an upper limit height H2 of 1500 mm, and the height width Hw of the appropriate operation range is 700 mm.

[0104] In this embodiment, the height from the road surface of the monitor passage 28 to the bottom surfaces of the first housing 60a and the second housing 60b (=height of the stand 55+height of the third housing 60c) is set so that all of the operation objects arranged on the first housing 60a and the second housing 60b are within the appropriate operation range. This height can be any as long as all of the operation objects are within the appropriate operation range, but by setting it to, for example, 800 mm, the same as the lower limit height H1 of the appropriate operation range, all of the operation objects arranged on the first housing 60a and the second housing 60b are placed at positions above the lower limit height no matter where they are placed.

[0105] Next, we will explain how to make the fire hydrant device thinner. As shown in Figure 4, in order to reduce the restriction on the passage width of the guard passage 28 caused by the protrusion (projection) of the fire hydrant device 10 (10-1) installed on the road surface of the guard passage 28 from the tunnel wall surface 35, the fire hydrant device 10 (10-1) is made as thin as possible.

[0106] The thinning of the fire hydrant device 10 (10-1) is optimized to match the equipment stored inside the fire hydrant device 10 (10-1). In the embodiment, the fire extinguisher stored in the second housing 60b is the device with the largest front-to-rear size among the equipment stored inside the fire hydrant device 10 (10-1), and the depth width (thickness in the front-to-rear direction) of the fire hydrant device 10 (10-1) can be thinned to a size that can accommodate the fire extinguisher, so the depth width of the fire hydrant device 10 (10-1) is set to a predetermined depth width that corresponds to the outer diameter of the fire extinguisher stored in the second housing 60b.

[0107] The fire extinguisher stored in the second housing 60b of the fire hydrant apparatus 10 (10-1) is, for example, a 20-type fire extinguisher with a 6 kg agent capacity, and the outer diameter of the 20-type fire extinguisher is approximately 160 to 180 mm. Therefore, if a gap is provided so that the stored fire extinguisher does not come into contact with the second housing 60b, the minimum depth of the fire hydrant apparatus 10 (10-1) is set to 250 mm, for example, within a range of approximately 200 to 250 mm, and the depths of the first housing 60a to the fifth housing 60e are all set to 250 mm. In contrast, the depth of a fire hydrant apparatus that is installed by boxing out the tunnel wall of the tunnel body is 300 mm or more. Therefore, the depth of the fire hydrant apparatus 10 (10-1) of the embodiment is reduced compared to a fire hydrant apparatus that is installed by boxing out the tunnel wall, and the fire hydrant apparatus 10 (10-1) can be made thinner.

[0108] Next, the reduction in the height of the fire hydrant device will be described. As shown in Fig. 4, the height width (vertical width) of the first housing 60a and the second housing 60b, in which the bottom surfaces of the housings are installed at a height H1 above the road surface of the guard passage 28 by the stand 55 and the third housing 60c, is set to the minimum height width necessary to accommodate the tallest device among the devices housed in the first housing 60a and the second housing 60b. In this embodiment, since there is no need to house a fire hose in the first housing 60a, the tallest device is a fire extinguisher housed in the second housing 60b, as in the case of the aforementioned thinning, and the height width (vertical width) of the second housing 60b is set to the minimum height width that can accommodate the fire extinguisher.

[0109] As in the case of the aforementioned thinning, when a 20-type fire extinguisher with a 6 kg agent capacity is stored in the second housing 60b, the height of the 20-type fire extinguisher is about 600 mm, so if a gap is secured so that the stored fire extinguisher does not come into contact with the inner upper surface of the second housing 60b, the height of the second housing 60b can be set to, for example, 700 mm, and the height width of the first housing 60a and the second housing 60b can be set to a height equal to or less than the height width Hw (= 700 mm) of the appropriate operation range, making it possible to set the height from the road surface of the monitor passage 28 to the upper surfaces of the first housing 60a and the second housing 60b to be equal to or less than the upper limit height H2 (= 1500 mm) of the appropriate operation range. As a result, all of the operation targets arranged in the first housing 60a and the second housing 60b will be positioned at a height equal to or less than the upper limit height, no matter where they are placed.

[0110] [d. Detailed structure of fire hydrant equipment] Next, the detailed structure of the fire hydrant device will be described using the fire hydrant device 10 (10-1) as an example.

[0111] (d1. Internal structure of the first housing) First, the internal structure of the first housing of the fire hydrant unit, which serves as the fire hydrant equipment storage section, will be described with reference to Figure 5, which shows the internal structure of the fire hydrant device in Figure 2 from the front (front) with the fronts of the first, third, fourth, and fifth housings opened.

[0112] 3 through a pipe through-hole 90a on the right bottom surface of the first housing 60a, and is connected to a pipe 104, to which a water hydrant 106 is branched. The pipe 104 is arranged in a downward U-shape, and a fire hydrant valve 108 and an automatic pressure regulating valve 110 are connected in sequence midway along the pipe 104.

[0113] The fire hydrant valve 108 is provided with an interlocking box 128, and a wire connects it to an operation box 124 provided on the right side of a frame 116 arranged in a lattice pattern at the front inside the first housing 60a, and a known wire link mechanism is provided which transmits the rotation associated with the opening and closing operation of the fire hydrant valve opening / closing lever 126 of the operation box 124 to the interlocking box 128 via the wire, thereby opening and closing the fire hydrant valve 108.

[0114] Automatic pressure regulating valve 110 adjusts the pressure of fire water supplied to fire hose 114 so as to maintain a predetermined pressure. Pipe 104 continuing from automatic pressure regulating valve 110 is bent downward near the left side surface and is connected to fire hose 114 stored in third housing 60c by hose joint 112 provided near the left bottom surface.

[0115] A hose outlet 118 is formed in a frame 116 arranged at the front inside the first housing 60a, and a water-discharge nozzle 120 is attached to the tip of a fire hose 114 that is pulled out from the third housing 60c into the first housing 60a through the hose outlet openings 88b, 88a shown in Fig. 3, and with the fire hose 114 pulled out through the hose outlet opening 118, the water-discharge nozzle 120 is detachably held in a nozzle holder 122. Note that the edges of the hose outlet openings 88a, 88b shown in Fig. 3 are framed using, for example, a pipe-shaped frame member to prevent wear and damage due to contact with the fire hose 114.

[0116] A pump start interlock switch 130 is provided inside the operation box 124. The pump start interlock switch 130 turns on when the fire hydrant valve opening / closing lever 126 is operated to the open position, and sends a pump start signal to the disaster prevention receiving panel to start the fire pump equipment. In addition, a pump start switch 132 is provided on the right side of the hydrant 106. When a firefighter connects a hose to the hydrant 106 to extinguish a fire, the pump start switch 132 is pressed to turn it on, and sends a pump start signal to the disaster prevention receiving panel to start the fire pump equipment.

[0117] (d2. Internal structure of the second housing) Next, the internal structure of the second housing of the fire hydrant unit, which serves as the electrical equipment storage section and the fire extinguisher storage section, will be described with reference to FIG.

[0118] As shown in Fig. 3, the interior of the second housing 60b is divided by a partition wall 94 into an electrical equipment storage section 94a and a fire extinguisher storage section 94b. As described above, the red indicator light 72, transmitter 74, and answer lamp 78 are disposed in the electrical equipment door 68 provided in the door opening on the front of the electrical equipment storage section 94a, a telephone jack 76 is disposed on the back surface of the electrical equipment door 74, and terminal boxes 75a and 75b are disposed on the rear surface of the housing inside the auxiliary door 70, as shown in Fig. 2. Furthermore, two fire extinguishers 69 are stored in the fire extinguisher storage section 94b.

[0119] (d3. Hose storage structure of the third housing) Next, the hose storage structure of the third housing of the hose storage unit will be described. In this description, in addition to Fig. 5, reference will be made to Fig. 6, which shows the hose storage shelf structure, and Fig. 7, which shows two cross sections of the internal structure of the fire hydrant device of Fig. 2, viewed from the right side. Fig. 6(A) shows the front (front side) of the hose storage shelf structure, and Fig. 6(B) shows the right side of the hose storage shelf structure. Fig. 7(A) shows the cross section along the cutting line aa in Fig. 5, and Fig. 7(B) shows the cross section along the cutting line bb in Fig. 5.

[0120] As shown in Fig. 5, intake piping 100 is arranged on the right side of the third housing 11c, and a partition wall 102 is arranged on the left side of the intake piping 100, forming a hose storage section 98 on the left side of the third housing 11c. As a hose storage structure for storing fire hoses 114, for example, hose storage shelf structures 134 are arranged at three locations in the left-right direction on the rear side (back side) of the hose storage section 98. The hose storage shelf structures 134 have a structure for holding the portions of the fire hoses 114 that pass above the hose storage section 98 and are generally parallel to the road surface of the monitor passage 28, of the fire hoses 114 that are stacked (wound inward) from the outside to the inside in the hose storage section 98 of the third housing 60c in an XY plane view.

[0121] As shown in Figure 6, the hose storage shelf structure 134 includes a back panel 138 and shelf members 136, and the shelf members 136 are arranged in multiple stages on the back panel 138 extending in the vertical direction, corresponding to the hose passing positions where the inwardly wound fire hose 62 passes above the hose storage section 98 and is roughly parallel to the road surface of the guard passage 34.

[0122] Here, shelf member 136 is fixed to back plate 138 and includes a vertical plate portion extending in the up-down direction and an inclined plate portion bent obliquely upward and forward from the lower side of the vertical plate portion, with the inclined plate portion inclined at a predetermined inclination angle θ with respect to the bottom surface of hose storage section 98. The inclination angle θ of the inclined plate portion is arbitrary, but as shown in the top shelf member 136, it is set to a positive angle, for example, a predetermined angle of around 10°, so that when a fire hose 114 is passed through shelf member 136, the fire hose 114 will not easily slip out from the inclined plate portion forward. Note that if the front end of the inclined plate portion is bent upward to form a slip-out prevention structure, the inclination angle θ may be set to 0° or a negative angle (inclined obliquely downward and forward).

[0123] The shelf members 136 are spaced vertically at intervals that allow one fire hose 114 to pass through (spacing that corresponds to the outer diameter of the hose). The number of tiers of shelf members 136 corresponds to the number of turns of the fire hose to be stored. For example, when a 30-meter fire hose 114 is wound inward in the hose storage section 98, the number of turns is six as shown in Figure 5, and therefore the shelf members 136 are arranged in six tiers.

[0124] For this reason, in the hose storage section 98, as shown in Figures 5 and 7(A)(B), the fire hose 114 is passed from top to bottom through shelf members 136 arranged in multiple stages on the upper side of the hose storage shelf structure 134 which is arranged in three locations in the left-right direction, and of the fire hose 62 wound inward by the shelf members 136, the part that passes above the hose storage section 98 and is roughly parallel to the road surface of the monitor passage 34 is supported (held) and stored in an inward wound state, for example, counterclockwise.

[0125] In addition, the front side of the hose storage shelf structure 134 is an empty space, forming a hose withdrawal space 140 for withdrawing the tip of the fire hose 114, which is supported by being wound inward on the hose storage shelf structure 134, toward the upper first housing 60a.

[0126] When a road user takes out the water discharge nozzle 120 held in the first housing 60a and pulls out the fire hose 114 in order to use the fire hydrant, the fire hose 114, which is supported by being wound inward on the hose storage shelf structure 134, passes through the hose pull-out space 140 in front, is pulled up to the upper first housing 60a side, and is then pulled out to the outside from the hose outlet 118, so that the fire hose 114 can be pulled out smoothly with little force without causing any unreasonable bends or folds in the pulled-out fire hose 114.

[0127] (d4. Fire hydrant door opening and closing mechanism) Next, the door opening / closing mechanism of the hydrant door will be explained. In this explanation, reference will be made to Fig. 8, which shows the fire hydrant device of Fig. 2 from the front (front) with the hydrant door open, and Fig. 9, which shows the door opening / closing mechanism of the hydrant door in cross section as seen from the right side of the fire hydrant device. Note that Fig. 9(A) shows the state in which the hydrant door is closed (closed position), Fig. 9(B) shows the state in which the hydrant door is opened 180 degrees (open position), and Fig. 9(C) shows the state in which the hydrant door is held approximately parallel to the road surface of the monitor's passage during hose rewinding work.

[0128] When a road user operates the door open / close handle 6410 of the hydrant door 64 to perform firefighting activities using the hydrant equipment and unlocks it, the hydrant door 64 opens downward about the hinge 64a at the lower end as an axis, as shown in Fig. 8, and the water discharge nozzle 120, the hydrant valve open / close lever 126, the water hydrant 106, and the pump start switch 132 arranged inside the first housing 60a become operable. In addition, on the back surface of the hydrant door 64, a stay 164 for holding the hydrant door 64 in an open state approximately parallel to the road surface of the monitor passage 28 is arranged corresponding to a pin 166 arranged approximately in the center of the frames 116 arranged on both the left and right sides and standing upright in the vertical direction, and is arranged so as to be rotatable about the axis at the upper end of the open hydrant door 64 as shown in Fig. 8.

[0129] 9(A), the door opening / closing mechanism 170 for the hydrant door 64 pivotally supports the hydrant door 64 on the lower side of the door opening of the first housing 60a by a hinge 64a serving as a shaft so that the hydrant door 64 can be opened and closed freely, and further includes a damper 176 that functions as a shock absorber. One end of the damper 176, which is the cylinder side, is fixed to the frame 116 or the like inside the housing by a fixed-side shaft 178, and the other end, which is the rod side, is pivotally supported by a shaft 172 to a damper mounting part 174 provided on the inside of the lower end of the hydrant door 64. In addition, in order to smoothly rotate the hydrant door 64 180 degrees to open it, the damper mounting part 174 is tilted at a predetermined angle so that the rear side (the housing interior side) is positioned higher than the front side when the hydrant door 64 is closed, and a downward force is applied by the damper 176 when the hydrant door 64 is opened.

[0130] When a road user pulls the door opening / closing handle 6410 toward themselves to unlock the hydrant door 64, the hydrant door 64 rotates downward 180° around the hinge 64a as an axis and opens to a position facing the front of the third housing 60c, and is positioned approximately perpendicular to the road surface of the guard passage 28, as shown in Figure 9(B).

[0131] Furthermore, when recovery workers drain the fire hose 114 that was pulled out after using the hydrant and rewind it into the box-shaped area of ​​the hose storage section 98 of the third housing 60c, as shown in Figure 9(C), by engaging a stay 164 arranged on the back side of the hydrant door 64 with a pin 166 arranged on the frame 116 inside the first housing 60a, it is possible to maintain the hydrant door 64 in an open state approximately parallel to the road surface of the monitor passage 28. This means that the open state of the hydrant door 64 of the first housing 60a does not interfere with the opening of the hose storage door 80 of the third housing 11c.

[0132] Next, we will explain the work of rewinding the fire hose after using the fire hydrant equipment. After a road user opens the fire hydrant door 64, removes the water discharge nozzle 120, and pulls out the fire hose 114 to carry out firefighting activities, the recovery worker drains the water from the used fire hose 114 and then rewinds the fire hose 114 into the hose storage section 98 of the third housing 60c.

[0133] Specifically, first, as shown in Figure 9(C), the fire hydrant door 64 is held in an open position approximately parallel to the road surface of the monitor passage 28 by the stay 164, and the operating handle 8010 of the hose storage door 80 shown in Figure 2 is operated to release the lock, and the hose storage door 80 is opened downward.

[0134] Next, the water discharge nozzle 120 attached to the tip of the fire hose 114 that has been pulled out to the outside from the door opening opened by the fire hydrant door 64 is removed to drain the water, and the fire hose 114 that has been drained is accessed through the door opening opened by the hose storage door 80, and the fire hose 114 that has been pulled out to the outside from the door opening opened by the fire hydrant door 64 is pulled toward the third housing 60c and pulled out entirely to the outside of the third housing 60c through the door opening of the hose storage door 80.

[0135] Thereafter, the fire hose 114 is passed through the door opening of the third housing 60c onto the shelf members 136 arranged in multiple stages above the hose storage shelf structure 134 in order from top to bottom, and the fire hose 62 is rewound inward into the hose storage section 98 of the third housing 60c while supporting the portion of the fire hose 62 that is rewound inward in the hose storage shelf structure 134 that passes above the hose storage section 98 and is generally parallel to the road surface of the monitor passage 34. After the rewinding of the fire hose 114 is completed, the tip of the fire hose 114 is passed through the hose outlet opening 88b of the third housing 60c and the hose outlet opening 88a of the first housing 60a shown in Figure 3 and is pulled out from the inside of the first housing 60a through the hose outlet 118, and the water discharge nozzle 120 is attached to the tip of the fire hose 114 and held in the nozzle holder 122, thereby completing the recovery work.

[0136] In this way, when the fire hose 114 is rewound inward with the support of the first hose storage shelf structure 134 of the hose storage section 98, no dedicated jig is required, and the fire hose 114 can be simply and easily rewound into the hose storage section 98 of the third housing 60c. Furthermore, in the case of the rewinding work of the fire hose after the assembly of the fire hydrant device is completed in the manufacturing process at the factory, the fire hose 114 can be simply and easily rewound without the need for a dedicated jig, just like the unwinding work of the fire hose.

[0137] (d5. Structure of evacuation guidance units) Next, the structure of the evacuation guidance unit will be described. In this description, reference will be made again to Figure 5. As shown in Figure 5, evacuation guidance units 16 and 17 are arranged on the left and right sides of a fire hydrant unit 12 having a first housing 60a and a second housing 60b arranged above and below, and a hose storage unit 14 having a third housing 60c.

[0138] Taking the evacuation guidance unit 16 arranged on the right side as an example, a rope fixing part 142 is arranged on the right side inside the fourth housing 60d, and one end (left end) of a guide rope 18 stretched between the evacuation guidance unit 16 and the fire hydrant device 10 (10-2) is fixed to the rope fixing part 142. Also, as shown in FIG. 1(B), the signal lines 34a and 34b of the LED tape 30 attached to the guide rope 18 are connected to an evacuation guidance controller 148 inside the fourth housing 60d.

[0139] Furthermore, a speaker 22a is disposed on the upper right side inside the fourth housing 60d, and the speaker 22a is also connected to the evacuation guidance controller 148. The structure and type of the speaker 22a are arbitrary, but it is desirable that the speaker 22a be a directional speaker that has directionality toward the adjacent fire hydrant device 10 (10-2) in order to output guidance messages to evacuees who are evacuating along the guide rope 18.

[0140] A storage shelf 144 is arranged on the lower side inside the fourth housing 60d, and the storage shelf 144 is vertically divided into, for example, eight shelves, and a portable respirator 146 is stored in each shelf so that it can be freely removed.

[0141] The structure and type of portable breathing apparatus 146 are arbitrary, but for example, it may be composed of an oxygen cylinder and a mask, or an air cylinder, a valve, and a mask, and by taking out and using portable breathing apparatus 146, evacuees can safely evacuate even in smoke. Also, portable breathing apparatus 146 can be taken out and used by opening fixture door 86 shown in Fig. 2, but a viewing window may be provided in fixture door 68 so that the presence of portable breathing apparatus 146 can be visually confirmed.

[0142] The evacuation guidance unit 17 installed on the left side is basically the same as the evacuation guidance unit 16, and the evacuation guidance unit 17 has a storage shelf 144 in which a rope fixing part 142, a speaker 22, and a portable breathing apparatus 146 are stored within the fifth housing 60e, but the signal lines 34a, 34b of the LED tape 30 attached to the guide rope 18 fixed to the rope fixing part 142 are connected to the evacuation guidance controller 148 of the evacuation guidance unit 16 located on the right side of the fire hydrant device located on the left side of the fire hydrant device 10 (10-1), so no evacuation guidance controller 148 is provided.

[0143] The evacuation guidance controller 148 may be provided on the evacuation guidance unit 17 side, rather than on the evacuation guidance unit 16 side. Furthermore, if the LED tape 30 attached to one guide rope 18 is divided into two halves, for example, evacuation guidance controllers 148 may be provided on both evacuation guidance units 16 and 17, and the signal lines 34a and 34b of one LED tape 30 may be connected to the evacuation guidance controller 148 of the evacuation guidance unit 16 arranged to the right of one fire hydrant device, and the signal lines 34a and 34b of the other LED tape 30 may be connected to the evacuation guidance controller 148 of the evacuation guidance unit 17 arranged to the left of the other fire hydrant device.

[0144] (d6. Operation control of evacuation guidance units) Next, the operational control of the evacuation guidance unit will be explained. In this explanation, reference will be made to Fig. 10, which shows the functional configuration of the evacuation guidance unit provided in the fire hydrant device of Fig. 2, and Fig. 11, which shows a plan view of the evacuation direction in the event of a fire occurring in a tunnel. In Fig. 10, three fire hydrant devices 10 (10-1) to 10 (10-3) are shown as representative fire hydrant devices, and the functional configuration of the evacuation guidance unit is shown with the fire hydrant device 10 (10-1) as the representative.

[0145] As shown in Figure 10 as a representative example of a fire hydrant device 10 (10-1), an evacuation guidance controller 148 is connected to a transmission line 152 drawn into the tunnel from a disaster prevention receiving panel 150. The evacuation guidance controller 148 is made up of a computer circuit equipped with a CPU, memory, various input / output ports, etc., and is provided with a control unit 154 as a function realized by executing a program, and a transmission unit 156, drive circuit units 158 and 160, and an audio drive unit 162 are provided for the control unit 154.

[0146] The transmission unit 156 transmits and receives signals including control commands, control data, etc. to and from the disaster prevention receiving panel 150 via the transmission path 152 in accordance with a predetermined communication protocol. A unique address that differs from one another is set in the transmission unit 156 for each evacuation guidance controller 148, and when the transmission unit 156 receives a signal including its own address, it transmits a predetermined signal to the control unit 154, and when it receives a signal from the control unit 154, it transmits a signal to the disaster prevention receiving panel 150 with its own address set as the sender.

[0147] The drive circuit unit 158 ​​is connected to the LED tape 30 attached to the guide rope 18 fixed to the rope fixing portion 142 of the evacuation guidance unit 16, and when the transmission unit 156 receives an evacuation guidance control signal specifying its own address from the disaster prevention receiving panel 150, it passes electricity through the signal lines 34a, 34b of the LED tape 30, causing the LEDs of the LED tape 30 to emit light.

[0148] The drive circuit unit 160 is connected to the left direction indicators 82a, 82b and right direction indicators 84a, 84b of the evacuation guidance units 16, 17, and when the transmission unit 156 receives an evacuation direction control signal specifying its own address from the disaster prevention receiving panel 150, it drives the left direction indicators 82a, 82b or the right direction indicators 84a, 84b to show the appropriate evacuation direction.

[0149] The audio driving unit 162 is connected to the speakers 22a, 22b of the evacuation guidance units 16, 17, and when the transmission unit 156 receives an audio control signal specifying its own address from the disaster prevention receiving panel 150 and the control unit 154 reads out, for example, predetermined audio message data stored in memory in advance, converts it into an audio message signal, and transmits it to the audio driving unit 162, the audio driving unit 162 causes the speakers 22a, 22b to output an evacuation guidance message.

[0150] As shown in Figure 11, if a fire caused by the fire vehicle 24 occurs between the fire hydrant devices 10 (10-4) and 10 (10-5), the occupants of the vehicle 25 on the left side, which is blocked by the fire vehicle 24, will use the lookout passage 28 and evacuate in a direction away from the fire vehicle 24. Naturally, the occupants of the vehicle on the right side of the fire vehicle 24 will also evacuate, but this will not be discussed here. In addition, an emergency exit 36 ​​is installed midway along the lookout passage 28 between the fire hydrant devices 10 (10-2) and 10 (10-3), and the emergency exit 36 ​​serves as the entrance to the evacuation tunnel.

[0151] In this case, the disaster prevention receiving panel 150 determines the location of the fire and the section between the fire hydrant device 10 (10-4) and the fire hydrant device 10 (10-5) as the location of the fire from the fire signal from the fire detector installed in the tunnel or information from the surveillance camera, etc., and transmits an evacuation guidance control signal specifying the address of each of the transmission units 156 of the evacuation guidance controllers 148 of the fire hydrant devices 10 (10-1) to 10 (10-5), and energizes the LED tape 30 of the guide rope 18 stretched between each of the fire hydrant devices 10 (10-1) to 10 (10-5) to drive the LED 32 to emit light, allowing evacuees to see the position of the guide rope 18. Furthermore, the guide ropes 18 that drive the LEDs 32 to emit light may be limited to the guide ropes 18 near the location of the fire, which is significantly affected by the reduced visibility due to smoke. For example, the LEDs 32 on the guide ropes 18 between the fire hydrant device 10 (10-3) and the fire hydrant device 10 (10-4) and the guide ropes 18 between the fire hydrant device 10 (10-4) and the fire hydrant device 10 (10-5) may be driven to emit light.

[0152] The disaster prevention receiving panel 150 also specifies the addresses of the transmission units 156 of the evacuation guidance controllers 148 of the fire hydrant devices 10 (10-1) and 10 (10-2) to transmit a right direction control signal (evacuation direction control signal) that is a direction toward the location of the fire but also toward the emergency exit 36, and causes the right direction indicators 84a and 84b of the fire hydrant devices 10 (10-1) and 10 (10-2) to light up or flash. Note that for the fire hydrant device 10 (10-1), if the tunnel entrance is closer than the emergency exit 36, the disaster prevention receiving panel 150 causes the left direction indicators 82a and 82b to light up or flash.

[0153] In addition, the disaster prevention receiving panel 150 specifies the addresses of the transmission units 156 of the evacuation guidance controllers 148 of the fire hydrant devices 10 (10-3) and 10 (10-4) to transmit a left direction control signal (evacuation direction control signal) that is a direction away from the location of the fire and toward the evacuation exit 36, and causes the left direction indicators 82a and 82b of the fire hydrant devices 10 (10-3) and 10 (10-4) to light up or flash.

[0154] In addition, the disaster prevention receiving panel 150 specifies the address of the transmission unit 156 of the evacuation guidance controller 148 of the fire hydrant device 10 (10-5) and transmits a right direction control signal (evacuation direction control signal) in the direction away from the location of the fire, causing the right direction indicators 84a, 84b of the fire hydrant device 10 (10-5) to light up or flash.

[0155] The disaster prevention receiving panel 150 also designates the addresses of the transmission units 156 of the evacuation guidance controllers 148 of the fire hydrant devices 10 (10-1) to 10 (10-5) and transmits audio control signals to cause the speakers 22a and 22b to output evacuation guidance messages corresponding to the location of the fire, the location of the evacuation exit, etc. The evacuation guidance messages output from the speakers 22a and 22b are arbitrary. For example, the fire hydrant device 10 (10-1) may output guidance information encouraging the use of the guide rope 18 to get to the next fire hydrant device, such as "Please pass in front of the fire hydrant device and move onto the guide rope to the next fire hydrant device," and the fire hydrant device 10 (10-2) may output guidance information to the evacuation exit, such as "There is an evacuation exit on the way to the next fire hydrant device. The evacuation exit is XX meters away."

[0156] Therefore, even in a situation where visibility is poor due to smoke, evacuees can evacuate by following the guide rope 18, and in addition, visual information from left direction indicators 82a, 82b and right direction indicators 84a, 84b and audio information from speakers 22a, 22b enable correct evacuation.

[0157] Furthermore, in a situation where the fire hydrant system 10 (10-1) to 10 (10-5) is filled with smoke and it is difficult to breathe, evacuees can safely evacuate by opening the fixture doors 86 of the evacuation guidance units 16 and 17 and taking out and using the portable breathing apparatus 146. Note that an audio message for evacuation guidance may be output from the speakers 22a and 22b to notify the evacuation guidance units 16 and 17 that the portable breathing apparatus 146 is stored therein.

[0158] [e. Modification of the First Embodiment] Next, a modified example of the first embodiment of the evacuation guidance system will be described. In this description, reference will be made to Fig. 12, which shows a modified example of the first embodiment of the evacuation guidance system. Fig. 12(A) shows the configuration of the evacuation guidance system, and Fig. 12(B) shows a portion of the guide rope and the lighting device extracted from Fig. 12(A).

[0159] As shown in Figure 12(A), in this modified example, similar to the first embodiment, the fire hydrant device is composed of a fire hydrant unit 12, a hose storage unit 14, and evacuation guidance units 16 and 17, and the fire hydrant devices are installed on the guard passage 28 inside the tunnel at 50-meter intervals, such as fire hydrant devices 10 (10-1) and 10 (10-2), and guide ropes 18 are stretched between the fire hydrant devices.

[0160] The guide rope 18 is a soft rope made by twisting together fiber or synthetic resin materials, as in the first embodiment, but differs in that, as shown in Fig. 12(B), fluorescent tape 1810 is wound around the guide rope 18. The fluorescent tape 1810 is a tape coated with fluorescent paint of a predetermined color, such as yellow or green, and has a fluorescent effect that makes it visible even in the dark when illuminated with light.

[0161] In this modification, lighting devices 38 are installed at predetermined intervals along the tunnel wall above the guide rope 18. The installation intervals of the lighting devices 38 are arbitrary, but for example, 24 lighting devices 38 are installed at predetermined intervals in the range of 1.5 to 2.5 m, for example, 2 m intervals, on one guide rope 18.

[0162] The lighting devices 38 are connected in parallel to a wiring cable 40 stretched between the fire hydrant devices 10 (10-1) and 10 (10-2). The wiring cable 40 includes, for example, two signal lines, one on the positive side and one on the negative side, and is connected to a drive circuit section of an evacuation guidance controller 148 provided in the evacuation guidance unit 16 instead of the signal lines 34a and 34b of the LED tape 30 of the first embodiment.

[0163] In the event of a fire occurring inside the tunnel, when the transmission unit 156 of the evacuation guidance controller 148 receives an evacuation guidance control signal from the disaster prevention receiving panel, the drive circuit unit energizes the lighting device 38, causing the lighting device 38 to emit light onto the guide rope 18 wrapped around the fluorescent tape 1810. Therefore, even in a situation where visibility is poor due to smoke, evacuees can evacuate by reliably seeing the guide rope 18 and following it.

[0164] The rest of the configuration is basically the same as that of the first embodiment described above, so a description thereof will be omitted.

[0165] [f. Second embodiment of evacuation guidance system] Next, a second embodiment of the evacuation guidance system will be described.

[0166] (f1. Configuration of evacuation guidance system) First, the configuration of the evacuation guidance system will be described with reference to Fig. 13 showing a second embodiment of the evacuation guidance system.

[0167] As shown in FIG. 13, in the second embodiment, similar to the first embodiment, the fire hydrant device is composed of a fire hydrant unit 12, a hose storage unit 14, and evacuation guidance units 16 and 17, and the fire hydrant devices are installed on the guard passage 28 inside the tunnel at 50-meter intervals, such as fire hydrant devices 10 (10-1) and 10 (10-2).

[0168] In addition, in the second embodiment, a guide rope 48 is stretched between adjacent fire hydrant devices, for example, between the evacuation guidance unit 16 of the fire hydrant device 10 (10-1) and the evacuation guidance unit 17 of the fire hydrant device 10 (10-2), but differs from the first embodiment in that the guide rope 48 is stretched in the form of a loop that can move around in a circular motion.

[0169] In the second embodiment, a motor 42, a drive roller 44, and guide rollers 46a and 46b are provided as a rotation drive mechanism for rotating a guide rope 48. The drive roller 44 is driven by the motor 42 and is provided together with the motor 42 in the evacuation guidance unit 16, the guide roller 46a is provided in the evacuation guidance unit 17, and the guide roller 46b is provided at a high position on the tunnel wall above each of the evacuation guidance units 16 and 17, and the guide rope 48 is stretched in a loop via the drive roller 44 and the guide rollers 46a and 46b.

[0170] The lower part of the looped guide rope 48, between the drive roller 44 and the guide roller 46a, is the part that evacuees will grab onto, so as in the first embodiment, it is set at a height of 100 cm from the road surface of the guard passage 28, and the guide rope 48 is passed through hanging rings 20 placed at predetermined intervals to prevent the guide rope 48 from sagging.

[0171] In addition, the height of the upper part between the guide rollers 46b of the looped guide rope 48 can be set arbitrarily, but to prevent evacuees from accidentally grabbing it, it is set to a predetermined height that exceeds the height of the evacuees, for example, 2 m.

[0172] In addition, a pair of guide rollers 46c are arranged at the top of the looped guide rope 48, between the guide rollers 46b, and a tension roller 50 with a weight 52 suspended therefrom is arranged between the guide rollers 46c to apply a downward force to the top of the guide rope 48, applying tension to the looped guide rope 48 to prevent it from slackening.

[0173] Here, in the second embodiment, the guide rope 48 is rotated by the drive roller 44, so similar to the modified example of the first embodiment shown in Figure 12 (B), in which a signal line is not required for the guide rope 48, the evacuation guidance system is equipped with a lighting device (not shown), and fluorescent tape is wrapped around the guide rope 48.

[0174] (f2. Structure of evacuation guidance unit) Next, the structure of the evacuation guidance unit in the second embodiment will be described using the fire hydrant device 10 (10-1) as an example. In this description, reference will be made to Fig. 14, which shows the fire hydrant device of the second embodiment from the front (front). Note that the fire hydrant unit 12 and the hose storage unit 14 are basically the same as those in the first embodiment, and therefore their description will be omitted.

[0175] As shown in Figure 14, taking the evacuation guidance unit 16 located on the right side as an example, a drive roller 44 driven by a motor 42 is located on the right side inside the fourth housing 60d, and a guide rope 48 pulled in from the right side is passed through the drive roller 44 and pulled out toward a guide roller 46b installed on the tunnel wall diagonally upward to the right.

[0176] The drive roller 44 can be driven to rotate clockwise or counterclockwise by the motor 42, and when the drive roller 44 is driven to rotate clockwise, the guide rope 48 is rotated clockwise, and the lower part of the guide rope 48 that is grasped by the evacuee is moved to the left. When the drive roller 44 is driven to rotate counterclockwise, the guide rope 48 is rotated counterclockwise, and the lower part of the guide rope 48 that is grasped by the evacuee is moved to the right.

[0177] A rope cleaner 180 is disposed at the entrance and exit for the guide rope 48 on the right side and top surface inside the fourth housing 60d. The rope cleaner 180 may have any structure, but for example, it may have brush bristles standing upright on the inner peripheral surface inside the case through which the guide rope 48 passes, and the brush bristles remove dirt from the guide rope 48 passing inside the case, maintaining it in a clean state.

[0178] Furthermore, an evacuation guidance controller 148 is disposed below the motor 42 inside the fourth housing 60d, a speaker 22a is disposed at the upper part of the right side inside the fourth housing 60d, and a storage shelf 144 is disposed at the lower part inside the fourth housing 60d, which stores a portable breathing apparatus 146 in a freely removable manner. Furthermore, although not shown, a fixture door 86 is disposed on the front side of the fourth housing 60d, and left direction indicators 82a, 82b and right direction indicators 84a, 84b which indicate the evacuation direction are disposed above the fixture door 86.

[0179] The evacuation guidance unit 17 installed on the left side is basically the same as the evacuation guidance unit 16, except that it has a guide roller 46a instead of the motor 42 and drive roller 44, but in other respects is the same as the evacuation guidance unit 16, and is equipped with an evacuation guidance controller 148, a speaker 22b, a storage shelf 144 containing a portable respirator 146, and a rope cleaner 180.

[0180] (f3. Operation control of evacuation guidance units) Next, the operational control of the evacuation guidance unit of the second embodiment will be described. In this description, reference will be made to Fig. 15, which shows the functional configuration of the evacuation guidance controller provided in the fire hydrant apparatus of Fig. 14. In Fig. 15, three fire hydrant apparatuses 10 (10-1) to 10 (10-3) are shown as representative fire hydrant apparatuses, and the functional configuration of the evacuation guidance unit is shown with the fire hydrant apparatus 10 (10-1) as the representative.

[0181] As shown in Figure 15 as a representative example of a fire hydrant device 10 (10-1), an evacuation guidance controller 148 is connected to a transmission line 152 drawn from a disaster prevention receiving panel 150 into the tunnel. The evacuation guidance controller 148 is composed of a computer circuit equipped with a CPU, memory, various input / output ports, etc., and is provided with a control unit 154 as a function realized by executing a program, and is provided with a transmission unit 156, drive circuit units 160 and 164, and an audio drive unit 162 for the control unit 154. Note that the transmission unit 156, drive circuit unit 160, and audio drive unit 162 are basically the same as those in the first embodiment, and therefore their description will be omitted.

[0182] The drive circuit unit 164 is connected to the motor 42 of the evacuation guidance unit 16, and when the transmission unit 156 receives a drive control signal specifying its own address from the disaster prevention receiving panel 150, it drives the motor 42 and drives the drive roller 44 to rotate clockwise or counterclockwise.

[0183] The disaster prevention receiving panel 150 transmits a predetermined drive control signal to the fire hydrant device based on the relative positions of the location of the fire caused by the fire vehicle 24 and the emergency exit 36 ​​or the entrance / exit of the tunnel. For example, as shown in FIG. 11, if a fire caused by the fire vehicle 24 occurs in the section between the fire hydrant device 10 (10-4) and the fire hydrant device 10 (10-5), the disaster prevention receiving panel 150 specifies the address of the transmission unit 156 of the evacuation guidance controller 148 of the fire hydrant device 10 (10-1) and transmits a left rotation drive control signal (drive control signal) to move the lower part of the guide rope 48 in the direction toward the location of the fire but toward the emergency exit 36, causing the lower part of the guide rope 48 to rotate so as to move in the right direction.

[0184] In addition, the evacuation guidance controller 148 of the fire hydrant device 10 (10-2) controls the rotation of the guide rope 48 between the fire hydrant device 10 (10-2) and the fire hydrant device 10 (10-3). However, since there are evacuees heading towards the emergency exit 36 ​​from the fire hydrant device 10 (10-2) side and evacuees heading towards the emergency exit 36 ​​from the fire hydrant device 10 (10-3) side, and there are evacuees evacuating in different directions, it is desirable not to rotate the guide rope 48, and no drive control signal is sent from the disaster prevention receiving panel 150 to the evacuation guidance controller 148 of the fire hydrant device 10 (10-2).

[0185] In addition, the disaster prevention receiving panel 150 specifies the address of the transmission unit 156 of the evacuation guidance controller 148 of the fire hydrant device 10 (10-3) and transmits a right rotation drive control signal (drive control signal) to move the lower part of the guide rope 48 away from the location of the fire and toward the evacuation exit 36, thereby rotating the lower part of the guide rope 48 so that it moves in the left direction.

[0186] In addition, the disaster prevention receiving panel 150 specifies the address of the transmission unit 156 of the evacuation guidance controller 148 of the fire hydrant devices 10 (10-4), 10 (10-5) and transmits a left rotation drive control signal (drive control signal) to move the lower part of the guide rope 48 in a direction away from the location of the fire, and rotates the lower part of the guide rope 48 so that it moves in the right direction.

[0187] Here, the rotation speed (movement speed) of the guide rope 48 is arbitrary, but may be a predetermined speed corresponding to the movement speed of a person, for example. Since the movement speed of a person is, for example, 1 m / sec, some may move at the same speed as the movement speed of a person, some may move at a faster speed than the movement speed of a person, for example, 1.2 m / sec to 1.5 m / sec, so that the evacuees are guided to move in a pulling manner, and some may move at a slower speed than the movement speed of a person, for example, 0.5 m / sec to 0.8 m / sec, taking safety into consideration.

[0188] In addition, during normal times when no fire has occurred, the disaster prevention receiving panel 150 may specify the address of the transmission unit 156 of the evacuation guidance controller 148 and send a drive control signal to rotate the guide rope 48 using the rope cleaner 180 to clean the guide rope 48.

[0189] [g. Modification of the second embodiment] Next, a modified example of the second embodiment of the evacuation guidance system will be described with reference to Fig. 16 showing a modified example of the second embodiment of the evacuation guidance system.

[0190] As shown in Figure 16, in this modified example, the guide rope 48 stretched between adjacent fire hydrant devices, for example, between the evacuation guidance unit 16 of the fire hydrant device 10 (10-1) and the evacuation guidance unit 17 of the fire hydrant device 10 (10-2), is divided into two guide ropes 48a and 48b, and each guide rope can be rotated individually by drive motors 44a and 44b provided on the evacuation guidance unit 16 of the fire hydrant device 10 (10-1) and the evacuation guidance unit 17 of the fire hydrant device 10 (10-2).

[0191] Therefore, the length of the guide rope rotated by one drive motor can be shortened, and the drive motors 44a and 44b can be made smaller. Furthermore, when an emergency exit is installed midway along the guard passage, such as between the fire hydrant devices 10 (10-2) and 10 (10-3) shown in FIG. 11, the drive motor 44a can rotate the guide rope 48a so that the lower part of the guide rope 48a located on the fire hydrant device 10 (10-2) side moves to the right, and the drive motor 44b can rotate the guide rope 48b so that the lower part of the guide rope 48b located on the fire hydrant device 10 (10-3) side moves to the left. Other than that, the configuration and operational control of the evacuation guidance system are basically the same as those of the second embodiment, and therefore, description thereof will be omitted.

[0192] [h. Modifications of the present invention] Modifications of the evacuation guidance system according to the present invention will now be described. In addition to the above-described embodiment, the evacuation guidance system according to the present invention includes the following modifications.

[0193] (Evacuation Guidance System) In the above embodiments, the explanation was divided into a "first embodiment of the evacuation guidance system" in which the guide rope is fixedly stretched, and a "second embodiment of the evacuation guidance system" in which the guide rope is stretched in a movable loop, but the evacuation guidance system may also be a combination of the first and second embodiments.

[0194] (Disaster prevention equipment) In the above embodiment, the disaster prevention device is described as a fire hydrant device, but the disaster prevention device is not limited to a fire hydrant device, and for example, the disaster prevention device may be an evacuation guidance unit that is provided in the fire hydrant device of the embodiment.

[0195] (Fire hydrant equipment) In the above embodiment, the fire hydrant device is provided with evacuation guidance units on both sides of the hydrant body, and a guide rope is stretched between the evacuation guidance units of adjacent fire hydrant devices, but the fire hydrant device may be composed of only the hydrant body without the evacuation guidance units, and a guide rope may be stretched between the hydrant bodies of adjacent fire hydrant devices. Also, in the above embodiment, the fire hydrant body and the evacuation guidance units are installed in contact with each other, but they may also be arranged separately.

[0196] (Fire hydrant body) In the above embodiment, the hydrant body of the hydrant device is a stationary structure in which the third housing is installed on a stand on the road surface of the guard passage, and the first and second housings are attached and fixed on the third housing, but this is not limited to this, and a wall-mounted structure may also be used in which a stand is installed on the tunnel wall and the first to third housings, or the first and second housings, are installed on the installed stand. The evacuation guidance unit may also be a wall-mounted structure instead of a stationary structure, but the height of the guide rope needs to be designed so that it is easy for evacuees to handle.

[0197] (others) Furthermore, the present invention includes appropriate modifications that do not impair the objects and advantages thereof, and is not limited to the numerical values ​​shown in the above embodiments. [Explanation of symbols]
