Description

Technical Field

[0001] The present invention relates to a fire hydrant device installed in a tunnel for storing a fire hose, a fire extinguisher, etc.

Background Art

[0002] Conventionally, in tunnels such as highways and motorways, a fire hydrant device is installed as an emergency facility in the tunnel. The fire hydrant device stores a fire hose with a nozzle attached to its tip and valves including a fire hydrant valve in a fire hydrant storage section of a housing equipped with a fire hydrant door (tilted forward door), and also stores, for example, two fire extinguishers in a fire extinguisher storage section equipped with a fire extinguisher door. In addition, the fire hydrant device is generally installed by cutting out the tunnel wall surface at intervals of, for example, 50 meters in the longitudinal direction of the tunnel and embedding it.

[0003] By the way, in a tunnel constructed by the shield method or the like, due to the structure of the tunnel body, it is difficult to cut out the tunnel wall surface and embed the fire hydrant device due to cost and labor, so it is necessary to install the fire hydrant device in an exposed state in the monitor passage.

[0004] In addition, in order to install the fire hydrant device without cutting out the tunnel wall surface, a wall-mounted structure has been proposed in which the fire hydrant device is attached and fixed to a gantry installed on the tunnel wall surface. In this case, the gantry is composed of a main support portion fixed to the wall surface and a posture holding member that holds the posture of the fire hydrant device (Patent Document 2).

[0005] In addition, since the wall-mounted fire hydrant device has problems such as taking a lot of labor and time to attach to the tunnel wall surface, it is considered to adopt a so-called standing structure in which the fire hydrant device is attached and fixed in an exposed state to a gantry installed on the road surface of the monitor passage where installation is easy.

[0007] Incidentally, the guard walkway, constructed along the tunnel wall at a higher elevation than the road, is also used as an evacuation route in the event of an emergency such as a fire caused by a vehicle accident. In order to avoid obstructing passage on the guard walkway when fire hydrant equipment is installed in a wall-mounted or freestanding manner and exposed on the guard walkway, the fire hydrant equipment is made as thin as possible.

[0008] However, even with efforts to make the fire hydrant system thinner, it is still installed in a way that it protrudes into the guardian's walkway. When the guardian's walkway is used as an evacuation route, there remains a possibility that evacuees trying to evacuate in a hurry may bump into the corner of the fire hydrant system that protrudes into the guardian's walkway, causing them to fall or get injured.

[0009] The present invention aims to provide a fire hydrant system that enables the securing of safe evacuation routes for fire hydrant systems that are installed exposed on the walls of monitoring walkways or tunnels. [Means for solving the problem]

[0013] (Equipment is stored inside the cover enclosure) The cover housing located on the fire extinguisher storage side of the enclosure can accommodate specified equipment inside. This equipment includes spare equipment for repair and replacement, tools, work materials, and inspection jigs.

[0014] (Text displayed on the side of the cover) The cover housing located on the side of the main unit that houses the fire hydrant equipment has the word "fire hydrant" written vertically on its side, while the cover housing located on the side of the main unit that houses the fire extinguisher has the word "fire extinguisher" written vertically on its side.

[0015] (Fire hydrant device of the second invention) The present invention relates to a fire hydrant device in which a housing is installed at a predetermined height above the road surface of a monitoring walkway provided along the wall of a tunnel having a road, so as to be close to or in contact with the tunnel wall, A cushioning member is positioned at the corner where the front and side surfaces of the housing meet in the height direction, and this cushioning member is positioned on both the side of the housing that houses the fire hydrant equipment and the side that houses the fire extinguisher.

[0016] (A cushioning material that covers the sides of the enclosure) The cushioning material is positioned to cover the sides of the housing, in addition to the corners.

[0017] (Text displayed on the cushioning material placed on the side of the enclosure) The buffer member arranged on the side of the housing for storing fire hydrant equipment has the characters "Fire Hydrant" vertically displayed on its side surface, and the buffer member arranged on the side of the housing for storing fire extinguishers has the characters "Fire Extinguisher" vertically displayed on its side surface.

[0018] (Fire Hydrant Device of the Third Invention) The present invention is a fire hydrant device in which a housing is installed in proximity to or in contact with a tunnel wall surface at a predetermined height above the road surface of a monitor passage provided along the wall surface of a tunnel having a road, An identification member capable of identifying the presence of a corner is arranged at a corner where the front surface and the side surface of the housing contact in the height direction or in the vicinity of the corner, and the identification member is arranged on both sides of the housing, namely, the side for storing fire hydrant equipment and the side for storing fire extinguishers.

[0019] (Light Emission Driving of the Identification Member) The identification member includes a light emitting portion that lights up, blinks, or flickers when a predetermined condition is satisfied.

[0020] (Satisfaction of the Condition for Light Emission Driving) The satisfaction of the predetermined condition includes the case where a fire occurs, the case where a fire alarm operation is performed, or the case where the door of the fire hydrant equipment storage portion of the housing is opened.

[0021] (Character Display on the Side Surface of the Housing) In the fire hydrant device of the third invention, the housing has the characters "Fire Hydrant" vertically displayed on the side surface of the side for storing fire hydrant equipment, and the characters "Fire Extinguisher" vertically displayed on the side surface of the side for storing fire extinguishers.

[0022] (Mounting and Fixing of the Housing by a Mount on the Monitor Passage) In the fire hydrant devices of the first to third inventions, the housing is mounted and fixed to the upper part of a mount installed on the road surface of the monitor passage, being closer to the tunnel wall surface side.

[0023] (Buffer Member at the Corner of the Mount) [[ID=3)) A buffer member covering the corner with a curved surface is arranged at the corner where the front surface and the side surface of the mount contact in the height direction.

[0024] (Mounting and securing of the enclosure using a frame on the tunnel wall) In the fire hydrant device of the first to third inventions, the housing is attached and fixed to the road-facing front part of a frame installed on the tunnel wall above the road surface of the guardian's passage. [Effects of the Invention]

[0025] (Effects of the fire hydrant device of the first invention) In the fire hydrant device of the first invention, a cover housing is arranged on the side of the housing, with a curved surface formed at the corner where the front of the cover and the side of the cover meet in the height direction. Since this cover housing is arranged on both the side of the housing where the fire hydrant equipment is stored and the side where the fire extinguisher is stored, the corner that protrudes into the guardian's passage is curved, reducing the impact if an evacuee passing in front of the fire hydrant device hits this corner, thus enabling the securing of a safe evacuation route without the risk of falling or injury.

[0026] (Effect of the cover door) Furthermore, the cover housing is equipped with a lockable cover door that can be opened and closed. For example, the cover door is an L-shaped door body extending from the front to the side of the door, with a curved surface formed at the corner where the front and side of the door meet. It is supported so as to be able to open and close around the height of the front or side end of the door opening that extends from the front to the side of the cover housing, and opening the cover door allows access to the internal space of the cover housing.

[0027] (The effect of placing water supply piping inside the cover enclosure) Furthermore, the cover housing located on the side where the fire hydrant equipment is stored has the water supply piping routed into the housing inside, which hides the entry point of the water supply piping, improving its appearance and preventing deterioration due to soiling of the entry point of the water supply piping.

[0028] (The effect of storing accessories inside the cover enclosure) Furthermore, the cover housing located on the fire extinguisher storage side is designed to accommodate specific equipment inside. This equipment includes items used for the maintenance and management of the fire hydrant system, such as spare equipment for repair and replacement, tools, work materials, and inspection jigs. This allows necessary equipment to be removed from the cover housing and used at the fire hydrant system installation site.

[0029] (Effect of text display on the side of the cover) Furthermore, the cover housing located on the side housing the fire hydrant equipment has the word "fire hydrant" written vertically on its side, and the cover housing located on the side housing the fire extinguisher has the word "fire extinguisher" written vertically on its side. This makes the names of the emergency equipment visible from the side, in addition to the conventional horizontally written "fire hydrant" and "fire extinguisher" on the front of the housing, which are visible from the front.

[0030] (Effects of the fire hydrant device of the second invention) In the fire hydrant device of the second invention, a cushioning member is placed at the corner where the front and side surfaces of the housing meet in the height direction, and this cushioning member is placed on both the side of the housing housing that houses the fire hydrant equipment and the side housing the fire extinguisher. This reduces the impact on evacuees passing in front of the fire hydrant device if they come into contact with the corner, enabling them to stay safe and avoid tripping or getting injured.

[0031] (Effect of the cushioning material covering the sides of the enclosure) Furthermore, by positioning the cushioning material not only at the corners but also covering the sides of the housing, it protects the sides of the housing from impacts by foreign objects kicked up by vehicles passing through the tunnel, prevents soiling, and improves durability.

[0032] (Effect of text display on cushioning material placed on the side of the enclosure) Furthermore, the cushioning material located on the side where the fire hydrant equipment is stored has the word "fire hydrant" written vertically on its side, and the cushioning material located on the side where the fire extinguisher is stored has the word "fire extinguisher" written vertically on its side. This makes it possible to see the names of the emergency equipment from the side, in addition to the conventional display of "fire hydrant" and "fire extinguisher" written horizontally on the front of the housing, which is visible from the front.

[0033] (Effects of the fire hydrant device of the third invention) In the fire hydrant device of the third invention, an identification member capable of identifying the presence of a corner is placed at or near the corner where the front and side surfaces of the housing meet in the height direction. Since the identification member is placed on both the side of the housing that houses the fire hydrant equipment and the side that houses the fire extinguisher, evacuees attempting to pass in front of the fire hydrant device will be able to notice the presence of the corner by the identification member before reaching the fire hydrant device and pass in front of the fire hydrant device without hitting the corner, thereby ensuring a safe evacuation route.

[0034] (Effect of driving the light emission of the identification element) The identification member is equipped with a light-emitting part that lights up, flashes, or blinks when certain conditions are met, for example, when a fire occurs, when a fire alarm is activated, or when the fire hydrant door is opened. This strongly alerts evacuees passing in front of the fire hydrant to the presence of the corner, allowing them to reliably notice the corner before reaching the fire hydrant due to the light emitted by the identification member, and to pass in front of the fire hydrant without hitting the corner, thereby ensuring a safe evacuation route.

[0035] (Effect of text display on the side of the casing) Furthermore, in the fire hydrant device of the third invention, the housing has the words "fire hydrant" written vertically on the side where the fire hydrant equipment is stored, and the words "fire extinguisher" written vertically on the side where the fire extinguisher is stored. This makes it possible to see the names of the emergency equipment from the side, in addition to the conventional display of the names of the emergency equipment that is visible from the front by the words "fire hydrant" and "fire extinguisher" written horizontally on the front of the housing.

[0036] (Effect of mounting and securing the enclosure using a stand on the monitoring staff walkway) Furthermore, in the fire hydrant devices of the first to third inventions, the housing is mounted and fixed to the upper part of a frame installed on the road surface of the guardian's walkway, positioned closer to the tunnel wall, thereby suppressing the amount of protrusion into the guardian's walkway, and making it possible to easily and simply set the height of the transmitter installed in the fire hydrant device within the legally defined height range, and at a height that can be appropriately operated from the user's standing position.

[0037] (Effect of cushioning material at the corners of the support structure) Furthermore, when the housing is attached and fixed to a frame installed on the road surface of the monitoring walkway, a cushioning member is placed at the corner where the front and side of the frame meet in the height direction, covering the corner with a curved surface. This reduces the impact when an evacuee's foot hits the corner of the frame as they pass in front of the fire hydrant device, ensuring a safe evacuation route without the risk of falling or injury.

[0038] (Effect of mounting and securing the enclosure using a frame on the tunnel wall) Furthermore, in the fire hydrant devices of the first to third inventions, the housing is attached and fixed to the road-facing front part of a frame installed on the tunnel wall above the road surface of the guardian's passage, thereby suppressing the amount of protrusion into the guardian's passage, and making it possible to easily and simply set the height of the transmitter provided on the fire hydrant device within the legally defined height range, and at a height that can be appropriately operated from the user's standing position.

[0040] Embodiments of the fire hydrant device according to the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited to the following embodiments.

[0041] [Basic Concepts of the Embodiment] First, the basic concept of the embodiment will be explained. The embodiment generally relates to a fire hydrant system in which fire hydrant equipment, electrical equipment, a terminal box, and a fire extinguisher are arranged inside a housing.

[0042] Here, "fire hydrant system" refers to a type of emergency equipment installed in areas such as tunnels on expressways and motorways that are subject to fire suppression. It consists of a housing installed in the fire suppression area containing fire hydrant equipment such as fire hoses, electrical equipment such as red indicator lights and transmitters on an electrically operated door, a terminal box, and fire extinguishers. The concept includes fire hydrant facilities in which a fire hydrant system is installed.

[0043] Furthermore, the fire hydrant system is installed exposed at a predetermined height above the road surface of the guardian's walkway, which is provided along the inner wall of the tunnel containing the road. Here, "predetermined height" refers to a height at which the fire hydrant system can be installed in close proximity to or in contact with the tunnel wall. For example, it can be installed at the predetermined height by attaching and fixing the housing to the upper part of a frame installed on the road surface of the guardian's walkway, or by attaching and fixing it to the front part on the road side of a frame installed on the tunnel wall above the road surface of the guardian's walkway.

[0044] Furthermore, "framework" refers to a structure that supports objects using columns and beams, and although specific examples are not shown in the illustration, it includes concepts such as support base, foundation, base, pedestal, and base.

[0045] The fire hydrant system of this embodiment can be divided into first to third embodiments corresponding to the first to third inventions.

[0046] In the first embodiment of the fire hydrant device corresponding to the first invention, a cover housing is arranged on the side of the housing, with a curved surface formed at the corner where the front of the cover and the side of the cover meet in the height direction, and this cover housing is arranged on both the side of the housing where the fire hydrant equipment is stored and the side where the fire extinguisher is stored.

[0047] Here, "cover housing" refers to an auxiliary housing positioned to eliminate the corners of the original housing of the fire hydrant system, which houses the fire hydrant equipment, fire extinguishers, and electrical equipment, where the front and sides meet in the height direction. By making the corners of the cover housing that protrude into the supervisor's passageway curved, the impact on evacuees passing in front of the fire hydrant system is reduced if they come into contact with these corners, thereby ensuring a safe evacuation route.

[0048] Furthermore, the cover body is equipped with a lockable cover door that can be opened and closed, and the presence of the cover door makes it possible to utilize the internal space of the cover housing.

[0049] The shape, arrangement, and structure of the cover door are arbitrary, but as an example, the cover door is an L-shaped door body extending from the front to the side of the door, with a curved surface formed at the corner where the front and side of the door meet, and is supported so as to be able to open and close around the height direction of the front end or side end of the door opening extending from the front to the side of the cover housing.

[0050] The cover housing located on the side where the fire hydrant equipment is stored houses water supply piping that is routed and connected to the housing from below the supervisor's passageway.

[0051] Furthermore, the cover housing located on the fire extinguisher storage side is used as an equipment storage area inside, and is used to store designated equipment including spare equipment for repairing and replacing valves and electrical equipment, tools such as screwdrivers and wrenches, work materials such as helmets and gloves, and inspection jigs used for water discharge tests.

[0052] Furthermore, the cover housing located on the side housing the fire hydrant equipment has the word "fire hydrant" written vertically on its side, and the cover housing located on the side housing the fire extinguisher has the word "fire extinguisher" written vertically on its side, allowing the names of the emergency equipment to be visible from the side.

[0053] In the second embodiment of the fire hydrant device corresponding to the second invention, a buffer member is provided at the corner where the front and side surfaces of the housing meet in the height direction, with the buffer member covering the corner with a curved surface. This buffer member is provided on both the side of the housing that houses the fire hydrant equipment and the side that houses the fire extinguisher.

[0054] Here, "cushioning member" refers to a member positioned to cover the corner of the housing that protrudes into the monitoring staff passage with a curved surface. The material is, for example, hard rubber or synthetic resin, and it reduces the impact when an evacuee passing in front of the fire hydrant device comes into contact with the corner, thereby ensuring a safe evacuation route.

[0055] Furthermore, the cushioning material, positioned to cover the curved corners of the enclosure that protrude into the security personnel's walkway, is also positioned to cover the sides of the enclosure, protecting the sides from impact and soiling by foreign objects.

[0056] Furthermore, the cushioning material located on the side where the fire hydrant equipment is stored has the word "fire hydrant" written vertically on its side, and the cushioning material located on the side where the fire extinguisher is stored has the word "fire extinguisher" written vertically on its side, making it possible to see the names of the emergency equipment from the side.

[0057] Furthermore, the mounting frame for attaching and securing the enclosure to the monitoring staff walkway also includes a cushioning member that covers the corners where the front and side surfaces meet in the height direction, with a curved surface.

[0058] In the third embodiment of the fire hydrant device corresponding to the third invention, an identification member capable of identifying the presence of a corner is arranged at or near the corner where the front and side surfaces of the housing meet in the height direction, and the identification member is arranged on both the side of the housing that houses the fire hydrant equipment and the side that houses the fire extinguisher.

[0059] Here, "identification member" refers to a component that makes the presence of a corner conspicuous and visible, includes a conspicuous color or pattern, and is equipped with a light-emitting part that lights up or flashes when predetermined conditions are met, thereby informing evacuees of the presence of a corner protruding into the guardian's passageway before they reach the fire hydrant device, and enabling evacuees passing in front of the fire hydrant device to avoid being hit by the corner.

[0060] Furthermore, the predetermined conditions for activating the light-emitting part of the identification member are arbitrary, but include, for example, when a fire occurs (fire detected by a fire detector, etc.), when a fire alarm is activated using a transmitter, or when a fire hydrant door is opened.

[0061] Furthermore, in a fire hydrant device in which an identification member is provided at or near the corner of the housing, the housing has the words "fire hydrant" written vertically on the side where the fire hydrant equipment is housed, and the words "fire extinguisher" written vertically on the side where the fire extinguisher is housed, thereby enabling the name of the emergency equipment to be visible from the side.

[0062] The following describes specific embodiments. In the specific embodiments shown below, "the fire hydrant device is mounted and fixed on a stand installed on the monitoring staff passage inside the tunnel," and will be described in three parts: a first embodiment of the fire hydrant device in which a cover housing is placed on the side of the housing; a second embodiment in which a buffer member is placed to cover the corners of the housing with a curved surface; and a third embodiment in which an identification member is placed on or near the corners of the housing.

[0063] [Specific details of the embodiment] We will now explain the fire hydrant system in more detail. The explanation will be divided as follows: a. First embodiment of a fire hydrant system a1. Overview of fire hydrant systems a2. Installation of fire hydrant systems a3. Installation height and slimming of fire hydrant systems a4. Configuration that accommodates the miniaturization of fire hydrant systems. a5. Stand for fire hydrant system b. Structure of the fire hydrant housing and cover housing b1.

[0064] [a. First embodiment of a fire hydrant system] A first embodiment of a fire hydrant system in which a cover housing is positioned on the side of the housing will be described in more detail.

[0065] (a1. Overview of fire hydrant systems) A more detailed explanation of the fire hydrant system will follow. Figure 1 is an explanatory diagram showing the installation of the fire hydrant system inside the tunnel. Figure 1(A) shows the installation of the fire hydrant system as seen in the tunnel cross-section, and Figure 1(B) shows the installation of the fire hydrant system as seen in the direction of the tunnel wall.

[0066] As shown in Figure 1(B), the housing of the fire hydrant device 10 in this embodiment is divided into a first housing 11a and a second housing 11b.

[0067] A decorative frame 13a is attached to the front of the first housing 11a. The door opening of the decorative frame 13a is divided into upper and lower sections. A fire hydrant door (forward-tilting door) 12 that opens downward by hinge 12a is located on the lower side of the door opening, and a maintenance door 14 that opens upward by hinge 14a is located on the upper side of the door opening. The storage section for fire hydrant equipment, which is the interior of the first housing 11a, houses predetermined fire hydrant equipment, including fire hoses and valves such as fire hydrant valves.

[0068] A cover enclosure 32 is positioned on the right side of the first enclosure 11a. The cover enclosure 32 is provided with a cover door 32a, which is positioned to open horizontally to the left (clockwise) around the vertical axis (height direction) of the front end of the door opening 32d by a hinge 32b. The interior of the cover enclosure 32 serves as a storage space for the water supply piping 48 that is routed into the first enclosure 11a through the frame 30. The cover door 32a may also be positioned to open horizontally to the right (counterclockwise) around the vertical axis of the side end of the door opening 32d.

[0069] Furthermore, a decorative frame 13b is attached to the front of the second enclosure 11b. The decorative frame 13b has two separate door openings. The right-hand door opening has an electrical door 18 that opens horizontally to the right by a hinge 18a, while the left-hand door has an auxiliary door 20 that opens horizontally to the left by a hinge 20a, allowing access to the internal terminal boxes 26a and 26b. The electrical door 18 is equipped with electrical equipment such as a red indicator light 22, a transmitter 24, and a response lamp 25, and a telephone jack 28 is provided on the inside.

[0070] The red indicator light 22 is always lit, allowing the location of the fire hydrant device 10 to be identified from a distance. When a fire occurs (fire is detected by a fire detector, etc.) and the transmitter 24 is pressed, turning on the push-button switch, a transmission signal is sent, and a fire alarm is output from the disaster prevention receiving panel installed in the electrical room or elsewhere that receives this signal. The fire hydrant device 10 receives a response signal from the disaster prevention receiving panel, causing the red indicator light 22 to flash and the response lamp 25 to light up.

[0071] Furthermore, a fire extinguisher door 16 is provided in the door opening on the left side of the decorative frame 13b, which opens horizontally to the left by a hinge 16a, and two fire extinguishers can be stored inside the fire extinguisher door 16. In addition, a viewing window 17 is provided on the lower side of the fire extinguisher door 16, allowing the presence or absence of fire extinguishers to be checked from the outside.

[0072] A cover enclosure 34 is positioned on the left side of the second enclosure 11b. The cover enclosure 34 is provided with a cover door 34a, which is positioned to open horizontally to the right (counterclockwise) around the vertical axis (height direction) of the front end of the door opening by a hinge 34b. The interior of the cover enclosure 34 is used, for example, as a storage area for equipment used for the operation, management, and maintenance of emergency equipment, including the fire hydrant device 10. The cover door 34a may also be positioned to open horizontally to the left (clockwise) around the vertical axis of the side end of the door opening.

[0073] (a2. Installation of fire hydrant systems) A more detailed explanation will be given regarding the installation of fire hydrant equipment inside the tunnel. Below the cylindrical (circular cross-section) tunnel structure constructed by the shield tunneling method, a road 46 is constructed in the longitudinal direction (left-right direction) of the tunnel, and a monitoring walkway 35 is constructed at a predetermined height relative to the road 46, below the tunnel wall 26 along the rear side of the road 46.

[0074] Because it is difficult to cut out a box in the tunnel wall 26 constructed using the shield tunneling method to install the fire hydrant device 10, a support frame 30 is installed on the road surface of the monitoring walkway 35, close to the tunnel wall 26, and the connected first housing 11a and second housing 11b are attached and fixed onto the support frame 30 to install the fire hydrant device 10. Here, the height H1 of the support frame 30 is set so that the height from the road surface of the monitoring walkway 35 to the transmitter 24 located on the fire hydrant device 10 falls within the legally stipulated range of 800 mm to 1500 mm.

[0075] Furthermore, as shown in Figure 1(A), the frame 30 of this embodiment has a side shape that is an inverted trapezoid with the top side longer than the bottom side, and the rear side is an inclined surface that slopes diagonally downward along the curved shape of the tunnel wall 26. The upper end surface of the frame 30 is to which the first housing 11a and the second housing 11b, to which the fire hydrant device 10 is connected, are attached and fixed.

[0076] (a3. Installation height and thinning of fire hydrant systems) The installation height and thinning of the fire hydrant device will be explained in more detail. In order to reduce the constraint on the width of the passage due to the protrusion (overhang) of the fire hydrant device 10, which is installed on the road surface of the guardian passage 35 by the support frame 30, from the tunnel wall 26, the installation height of the fire hydrant device 10 has been optimized, and the fire hydrant device 10 has also been made as thin as possible.

[0077] First, since the installation height of the fire hydrant device 10 is determined by the support frame 30, we will explain in more detail how to optimize the height H1 of the support frame 30. Figure 2 schematically shows the installation state of the fire hydrant device in the tunnel cross-section. The tunnel wall 26 on which the fire hydrant device 10 is installed has a circular cross-section. In Figure 2(A), the height H1 of the support frame 30 is set such that the horizontal centerline SL2 of the housing of the fire hydrant device 10, which is installed on the monitoring walkway 35, is as close as possible to the horizontal tunnel centerline SL1 from the tunnel center (center of the circular cross-section) P.

[0078] In this case, the closer the housing centerline SL2 is to the tunnel centerline SL1, the less the fire hydrant device 10 protrudes from the tunnel wall 26.

[0079] Figure 2(B) shows the case where the height H1 of the support frame 30 is set so that the centerline SL2 of the housing coincides with the centerline SL1 of the tunnel. In this case, the degree to which the fire hydrant device 10 protrudes from the tunnel wall 26 can be minimized. However, the height H1 of the support frame 30 should be adjusted within a reasonable range, taking into account the removal of fire extinguishers, etc.

[0080] Next, the thinning of the fire hydrant device 10 will be explained in more detail. The largest component in the fire hydrant device 10 in the front-to-back direction is the fire extinguisher housed in the second housing 11b. Since the fire hydrant device can be made thinner if the width (thickness in the front-to-back direction) of the fire hydrant device is limited to the minimum size that the fire extinguisher can accommodate in the second housing 11b, the width of the fire hydrant device 10 is set to a predetermined width corresponding to the outer diameter of the fire extinguisher housed in the second housing 11b.

[0081] The outer diameter of a fire extinguisher is approximately 150-160 mm. If a gap is secured so that the stored fire extinguisher does not come into contact with the second housing 11b, the minimum width of the fire hydrant device 10 will be, for example, within a range of approximately 180-200 mm. The width of the fire hydrant device 10 is set to a predetermined width within this range. In contrast, the width of a conventional fire hydrant device 10, which is installed by cutting out a box in the wall of a tunnel structure, is approximately 300 mm. Therefore, the width of the fire hydrant device 10 in this embodiment can be reduced to 2 / 3 or less of the conventional width, making the fire hydrant device 10 thinner.

[0082] (a4. Configuration adapted to the miniaturization of fire hydrant systems) If the fire hydrant device 10 is made thinner to a predetermined width of approximately 180 to 200 mm, corresponding to the outer diameter of the fire extinguisher, it becomes difficult to store a fire extinguishing hose of a predetermined length, such as a 30 m shape-retaining hose, in the first housing 11a in an inward-curled state, as in conventional fire hydrant devices. Therefore, in this embodiment, by increasing the width (width in the left-right direction) of the first housing 11a, it becomes possible to store a shape-retaining hose of the same predetermined length as in conventional devices in an inward-curled state.

[0083] Furthermore, as the fire hydrant device 10 is made thinner, it becomes difficult to place the terminal box on the rear surface of the housing behind the fire extinguisher storage section where the fire extinguisher is housed, as is the case with conventional fire hydrant devices. Therefore, in this embodiment, the width (length in the left-right direction) of the second housing 11b is increased to accommodate not only the fire extinguisher storage but also the electrical equipment and the terminal box.

[0084] (a5. Stand for fire hydrant system) The fire hydrant system's mounting frame will be explained in more detail. Figure 3 is a perspective view of the mounting frame for attaching and fixing the fire hydrant system. The frame 30 is made, for example, by cutting angle material to a predetermined length and welding it into a box shape, with the angle material arranged so that when viewed from the side, it forms an inverted trapezoid with the top side longer than the bottom side.

[0085] On the upper end surface of the frame 30, mounting holes 31 are formed in pairs, front and back, at three locations along the longitudinal direction of the upper surface. The mounting holes 31 are formed in positions corresponding to the mounting holes at the bottom of the first housing 11a and the second housing 11b of the fire hydrant device 10. By aligning the mounting holes of both housings and inserting bolts and fitting nuts, the first housing 11a and the second housing 11b are attached and fixed to the frame 30.

[0086] [b. Structure of the fire hydrant system housing and cover housing] The structure of the fire hydrant system housing and cover housing will be explained in more detail with reference to Figures 4 to 6.

[0087] (b1. Structure of the first enclosure) The structure of the first housing 11a will be described in more detail. In this description, refer to Figure 4, which shows the internal structure of the fire hydrant system with the fire hydrant door and maintenance door open on the front; Figure 5, which shows the internal structure of the fire hydrant system in a cross-sectional view from above; and Figure 6, which shows a cross-sectional view of the hose storage section of the first housing in a cross-sectional view from the right side. Note that Figure 5 is the cross-section indicated by the cutting line aa in Figure 4, and Figure 6 is the cross-section indicated by the cutting line bb in Figure 4. Also, the fire hydrant door 12 in Figure 6 is shown as the side view of the door in Figure 4.

[0088] The interior of the first housing 11a, which houses the fire hydrant equipment, is divided into a valve storage section 50a and a hose storage section 50b. A water tap 52 is located in the valve storage section 50a, and the piping to the water tap 52 branches downward. A fire hydrant valve 54 and an automatic pressure regulating valve 56 are provided at the branch end, followed by a fire hose 60 using a shape-retaining hose.

[0089] The fire hydrant valve 54 is opened and closed by a fire hydrant valve opening / closing lever 58. When the fire hydrant valve opening / closing lever 58 is opened or closed, the fire hydrant valve 54 is remotely opened and closed by a known wire linkage mechanism. When the fire hydrant valve opening / closing lever 58 is opened or closed, a pump activation interlocking switch located in the control box is turned on or off. In addition, a pump activation switch 64 for use by the fire brigade is located to the upper right of the water tap 52.

[0090] A hose storage frame 62 is provided in the hose storage section 50b, and the fire extinguishing hose 60, which is pulled in from below, is stored in a clockwise or counterclockwise inward-curved state. Here, the hose storage frame 62 has been widened to accommodate the increased width of the first housing 11a due to the thinning of the fire extinguishing device 10, and it is possible to store the same predetermined length of fire extinguishing hose 60 with fewer turns compared to conventional fire extinguishing devices. In addition, a nozzle 68 is attached to the end of the fire extinguishing hose 60 that is pulled out through the hose guide 66, and the nozzle 68 is detachably held in the nozzle holder 70.

[0091] (b2. Cover cabinet on the right side of the first cabinet) The cover housing 32, located on the right side of the first housing 11a in which the fire hydrant equipment is housed, will be described in more detail. In this description, in addition to Figures 4 to 6, Figure 7, which shows the right side of the first housing 11a in which the cover housing is located, will be referred to. Figure 7(A) shows the cover door 32a in the closed state, and Figure 7(B) shows the cover door 32a in the open state.

[0092] As shown in Figure 7(A), the cover housing 32 positioned on the right side of the first housing 11a has a curved surface 32c formed at the vertical corner where the front and side surfaces of the cover meet. When positioned on the right side of the first housing 11a, the cover housing 32 eliminates (rounds) the vertical corner where the front and side surfaces of the first housing 11a meet.

[0093] Therefore, even if the fire hydrant device 10 is installed in an exposed state in the monitoring walkway 35, the corner of the cover housing 32 that protrudes into the monitoring walkway 35, including the cover door 32a, is a curved surface 32c. This reduces the impact if an evacuee passing in front of the fire hydrant device 10 comes into contact with the corner, ensuring a safe evacuation route without the risk of tripping or injury.

[0094] Furthermore, the cover housing 32 has a cover door 32a that is positioned on a hinge 32b so as to open sideways to the left, with the front end of the door opening as the axis in the vertical direction. The cover door 32a is an L-shaped door body that follows the cover housing 32 from the front of the door to the side of the door, and a curved surface 32c that continues towards the cover housing 32 is formed at the vertical corner of the door where the front of the door and the side of the door meet.

[0095] The structure and mechanism for holding or releasing the cover door 32a closed are arbitrary, but for example, an opening / closing lever 32e may be placed at the side end, and when the opening / closing lever 32e is operated, the lock is released, and the cover door 32a can be opened as shown in Figure 7(B). An engaging part 32f is placed at the door opening end corresponding to the opening / closing lever 32e, and can be locked or unlocked by operating the opening / closing lever 32e when the door is closed. The opening / closing lever 32e may also be lockable.

[0096] On the side of the cover door 32b, the word "Fire Hydrant," indicating the name of the emergency equipment, is displayed vertically. As shown in Figure 1, in addition to the word "Fire Hydrant" displayed horizontally on the fire hydrant door 12 of the first housing 11a, the word "Fire Hydrant" is also displayed vertically on the cover housing 32b, making it possible to see the name of the emergency equipment from the right side of the fire hydrant device 10, thereby expanding the viewing area.

[0097] The interior of the cover housing 32 is used, for example, as a pipe storage section 50d. As shown in Figures 4 and 5, a water supply pipe 48 is routed through a support frame 30 to the right side of the first housing 11a, and a pipe passage hole is formed in the bottom surface of the cover housing 32 so that the upper end of the water supply pipe 48 is located inside the cover housing 32 when the fire hydrant device 10 is attached and fixed to the support frame 30.

[0098] The water supply piping 48, which is drawn from the frame 30 into the interior of the cover housing 32, is connected to the piping that is brought out from the side of the first housing 11a via pipe 49a and elbow 49b. For this reason, as shown in Figure 7(B), a pipe passage hole 53 is formed on the inner side of the cover housing 32. Note that Figure 7(B) omits the illustration of these pipes.

[0099] In this way, by housing the water supply pipe 48, pipe 49a, and elbow 49b inside the cover housing 32 located on the side of the first housing 11a, the piping located on the side of the fire hydrant device 10 is covered by the cover housing 32, improving its appearance, and also improving its durability by preventing contamination of the piping.

[0100] (b3. Structure of the second enclosure) The second enclosure 11b is divided into an electrical equipment placement side and a fire extinguisher storage side. First, the structure of the electrical equipment placement side of the second enclosure 11b will be described in more detail. As shown in Figures 4 and 5, an electrical equipment door 18 that opens horizontally to the right by a hinge 18a is placed in the door opening on the right side of the second enclosure 11b. On the electrical equipment door 18, a red indicator light 22, a transmitter 24, and a response lamp 25 are arranged from top to bottom, and a telephone jack 28 is located inside the electrical equipment door 18.

[0101] Here, among the electrical equipment, the red indicator light 22 has the largest front-to-back dimensions inside the second housing 11b, and its size is approximately 120 mm. Therefore, even if the fire hydrant device 10 is made thinner to a predetermined width of approximately 180 to 200 mm, it is possible to arrange the electrical equipment while still securing space for the cables pulled in from the first housing 11a side.

[0102] Furthermore, an auxiliary door 20 that opens horizontally to the left by a hinge 20a is located to the left of the electrical door 18. As shown in Figures 4 and 5, terminal boxes 26a and 26b are arranged vertically on the rear surface of the housing inside the second housing 11b, opposite the auxiliary door 20. The auxiliary door 20 is opened together with the electrical door 18 when wiring cables are to be connected to the terminal boxes 26a and 26b, forming a work opening.

[0103] The terminal boxes 26a and 26b consist of a box body and a lid, and when placed on the second enclosure 11b, their dimensions (height (top and bottom) x width (left and right) x depth (front and back)) are approximately 220mm x 140mm x 80mm.

[0104] Therefore, even if the fire hydrant device 10 is made thinner to a predetermined width in the range of approximately 180 to 200 mm, the depth (front to back) of the terminal boxes 26a and 26b is approximately 80 mm, so sufficient space is secured inside the second housing 11b to accommodate the terminal boxes 26a and 26b. In addition, since the terminal boxes 26a and 26b are located close to electrical equipment such as the red indicator light 22 located on the first door 18, it is possible to connect the terminal boxes 26a and 26b to the electrical equipment with short wiring lengths.

[0105] In addition, some fire hydrant systems may include a transmission unit for sending and receiving fire alarm signals from a transmitter 24 located on the electrical door 18 and response signals to a response lamp 25 via a transmission path between the system and the fire prevention receiving panel. The second enclosure 11b has sufficient space to accommodate the transmission unit in addition to terminal boxes 26a and 26b.

[0106] Next, the structure of the fire extinguisher storage side of the second housing 11b will be explained in more detail. As shown in Figures 4 and 5, the inside of the fire extinguisher door 16 of the second housing 11b has space to store two fire extinguishers 72 with an outer diameter of approximately 150 to 160 mm. Also, as mentioned above, in order to make the fire hydrant device 10 thinner, the width of the fire hydrant device 10 is a predetermined width in the range of 180 to 200 mm corresponding to the outer diameter of the fire extinguisher 72. This ensures a gap of approximately 15 to 25 mm in front of and behind the stored fire extinguisher 72, allowing the fire extinguisher 72 to be stored without contacting the second housing 11b.

[0107] (b4. Cover cabinet on the left side of the second cabinet) The cover housing 34, located on the left side of the second housing 11b in which the fire extinguisher is housed, will be described in more detail. In this description, in addition to Figures 4 to 6, Figure 8, which shows the left side of the second housing 11b in which the cover housing 34 is located, will be referred to. Figure 8(A) shows the cover door in the closed position, and Figure 8(B) shows the cover door in the open position.

[0108] As shown in Figure 8(A), the cover housing 34 positioned on the left side of the second housing 11b has a curved surface 34c formed at the vertical corner where the front and side of the cover meet. When positioned on the left side of the second housing 11b, this eliminates (rounds) the vertical corner where the front and side of the second housing 11b meet.

[0109] Therefore, even if the fire hydrant device 10 is installed in an exposed state in the monitoring walkway 35, the corner of the cover housing 34 that protrudes into the monitoring walkway 35, including the cover door 34a, is a curved surface 34c. This reduces the impact if an evacuee passing in front of the fire hydrant device 10 comes into contact with the corner, ensuring a safe evacuation route without the risk of tripping or injury.

[0110] Furthermore, the cover housing 34 has a cover door 34a that opens sideways to the right on a hinge 34b, with the front end of the door opening as the axis in the vertical direction. The cover door 34a is an L-shaped door body that follows the cover housing 34 from the front of the door to the side of the door, and a curved surface 34c that continues towards the cover housing 34 is formed at the vertical corner of the door where the front of the door and the side of the door meet. The structure and mechanism for holding or releasing the cover door 34a closed are arbitrary, but for example, similar to the cover door 32b shown in Figure 7, it consists of an opening / closing lever 34e and an engaging part 34f. The opening / closing lever 34e may also be lockable.

[0111] On the side of the cover door 34b, the word "Fire Extinguisher," indicating the name of the emergency equipment, is displayed vertically. As shown in Figure 1, in addition to the word "Fire Extinguisher" displayed horizontally on the fire extinguisher door 16 of the second housing 11b, the vertical display of "Fire Extinguisher" on the cover housing 34b makes it possible to see the name of the emergency equipment from the left side of the fire hydrant device 10, thereby expanding the viewing area.

[0112] The interior of the cover housing 34 is used, for example, as a storage compartment 50e for equipment. As shown in Figure 8(B), the interior of the cover housing 34 is divided into multiple storage compartments by the arrangement of shelves 36, for example.

[0113] Any equipment can be stored in the equipment storage section 50e of the cover housing 34. For example, electrical equipment placed in the electrical door 18, spare replacement parts such as valves placed in the valve storage section 50a, tools such as screwdrivers and wrenches used for inspection and repair of the fire hydrant system 10, work equipment such as helmets and gloves used for operation and management of emergency equipment including the fire hydrant system 10, testing equipment such as test jigs used for actual water discharge tests of the fire hydrant system 10, and even life-saving equipment such as first-aid kits.

[0114] Furthermore, it is desirable that multiple types of equipment not be stored in the same fire hydrant device 10, but rather divided into groups of a predetermined number of fire hydrant devices and stored in a distributed manner within each group. It is also desirable that letters, figures, symbols, etc., indicating the stored equipment be written on the inner surface of the cover door 34 so that it can be identified at a glance. In addition, making the opening and closing lever 34e lockable can prevent tampering with or theft of these pieces of equipment.

[0115] [c. Second embodiment of the fire hydrant system] A second embodiment of a fire hydrant device in which a buffer member is placed at the corner of the housing will be described in more detail. In this description, refer to Figure 9 showing the second embodiment of the fire hydrant device, Figure 10 showing the internal structure of the fire hydrant device corresponding to the second embodiment, and Figure 11 showing the right side of the first housing 11a in which the buffer member is placed. Figure 9(A) shows the front view, Figure 9(B) shows the top view, Figure 9(C) shows the left side view, and Figure 9(D) shows the right side view.

[0116] As shown in Figure 9, the fire hydrant device 10 of this embodiment consists of a first housing 11a and a second housing 11b, and is attached and fixed to the upper end surface of a stand 30 located in the supervisory passageway. The details of the first housing 11a and the second housing 11b are the same as those of the first embodiment described above, so they are given the same reference numerals and their descriptions are omitted.

[0117] In this embodiment, as shown in Figures 9 and 11, a cushioning member 42 is arranged on the right side of the first housing 11a. The cushioning member 42 consists of a corner cover portion 42a that covers the corner where the front and side surfaces of the first housing 11a meet in the height direction, and a side cover portion 42b that covers the side surface. The material of the cushioning member 42 is arbitrary, but for example, hard rubber or synthetic resin can be used.

[0118] The corner cover portion 42a of the cushioning member 42 covers the protruding part of the housing corner, thereby reducing the impact if an evacuee passing in front of the fire hydrant device 10 comes into contact with the corner, enabling a safe evacuation route without the risk of falling or injury.

[0119] Furthermore, the side cover portion 42b of the cushioning member 42 protects the side of the housing from impacts by foreign objects bounced up by vehicles traveling on the road inside the tunnel, and also prevents contamination of the side of the housing by exhaust gases and dust inside the tunnel, thereby improving durability.

[0120] In this embodiment, a support cushion member 43 is also positioned on the right side of the housing 30, which is located below the right side of the first housing 11a. The support cushion member 43 is also composed of a corner cover portion 43a that covers the corner where the front and side of the support 30 meet in the height direction, and a side cover portion 43b that covers the side. The material of the cushion member 42 is arbitrary, but like the cushion member 42, hard rubber or synthetic resin is used.

[0121] The corner cover portion 43a of the support cushioning member 43 covers the protruding corner of the support, reducing the impact if an evacuee's foot hits the corner as they pass in front of the fire hydrant device 10, thus ensuring a safe evacuation route without causing falls or injuries. In addition, the side cover portion 43b of the support cushioning member 43 prevents soiling of the side of the housing and improves durability. Furthermore, the side of the cushioning member 42 located on the right side of the first housing 11a displays the word "fire hydrant" in vertical writing, making the emergency equipment name visible from the right side of the fire hydrant device 10.

[0122] Here, as shown in Figure 10, the water supply piping 48 is connected to the first housing 11a by passing through the support frame 30 and being drawn in from the bottom of the first housing 11a to connect to the water tap 52. The piping then branches downward from just before the tap and connects to the fire hydrant valve 54 and the automatic pressure regulating valve 56. The water supply piping 48 is drawn into the housing from the bottom, so it is not exposed to the outside.

[0123] Furthermore, in this embodiment, as shown in Figure 9, a cushioning member 44 is positioned on the left side of the second housing 11b, and a base cushioning member 45 is also positioned on the left side of the base 30. The configuration of the cushioning member 44 and the base cushioning member 45 is the same as that of the cushioning member 42 and base cushioning member 43 positioned on the right side of the first housing 11a and base 30, but the cushioning member 44 differs in that the word "fire extinguisher" is displayed vertically on its side.

[0124] Therefore, with respect to the second housing 11b, the protruding parts of the housing corners and the base corners are covered with the cushioning member 44 and the base cushioning member 45, thereby reducing the impact when evacuees passing in front of the fire hydrant device 10 come into contact with these corners, enabling the securing of a safe evacuation route without them falling or getting injured. In addition, the cushioning member 44, like the cushioning member 42, has the effect of protecting the sides of the housing from collisions with foreign objects bounced up by vehicles traveling on the road inside the tunnel, but this effect is greater on the fire extinguisher storage side (cushioning member 44 side), which is upstream of vehicle traffic, than on the fire hydrant side (cushioning member 42 side).

[0125] Furthermore, the cushioning member 42 and the frame cushioning member 43, and the cushioning member 44 and the frame cushioning member 45 may be integrated into a single structure. Alternatively, the frame cushioning members 43 and 45 may be omitted, and only the cushioning members 42 and 44 may be provided.

[0126] [d. Third embodiment of a fire hydrant system] A third embodiment of a fire hydrant device in which an identification member is positioned at the corner of the housing will be described in more detail. In this description, refer to Figure 12, which shows the third embodiment of the fire hydrant device, and Figure 13, which shows the light emission control unit.

[0127] (d1. Identification member at the corner of the housing) The identification members positioned at the corners of the housing of the fire hydrant device 10 will now be described in more detail. As shown in Figure 12, the fire hydrant device 10 of this embodiment consists of a first housing 11a and a second housing 11b, and is attached and fixed to the upper end surface of a stand 30 located in the supervisory passageway. The details of the first housing 11a and the second housing 11b are the same as those of the first and second embodiments described above, so they are given the same reference numerals and their description is omitted.

[0128] In this embodiment, as shown in Figure 12, an identification member 74 is positioned at the corner where the front and side surfaces of the first housing 11a meet in the height direction, and an identification member 76 is positioned at the corner of the right side surface where the front and side surfaces of the second housing 11b meet in the height direction. Note that the identification members 74 and 76 may also be positioned on the side surfaces near the corners.

[0129] The identification members 74 and 76 are designed to make users, especially evacuees using the monitoring staff passage, strongly aware of the presence of the outwardly protruding corners of the housing. Their structure and function are arbitrary, but for example, they may be fitted with conspicuous colors or patterns.

[0130] Furthermore, it is desirable that the identification members 74 and 76 are equipped with light-emitting parts, and that in an emergency the light-emitting parts be driven to illuminate, flash, or blink the identification members 74 and 76. The light emission control unit for the identification members 74 and 76 uses one of the functional configurations shown in Figure 13(A) or (B).

[0131] (d2. Embodiment of the light emission control unit) The embodiment of the light emission control unit shown in Figure 13(A) will be described in more detail. The configuration and functions of the light emission control unit are arbitrary, but for example, it consists of a controller 78, light-emitting units 80 and 82, a door switch 84, a transmitter 24, and a response lamp 25.

[0132] The controller 78, for example, uses hardware such as a computer circuit, and when predetermined conditions are met, it controls the light-emitting units 80 and 82 to light up, blink, or flash the identification members 74 and 76.

[0133] The light-emitting parts 80 and 82 are arbitrary, but for example, LEDs are provided as light-emitting elements. Here, the identification members 74 and 76 are, for example, light guides made of red light-transmitting material, and have a length corresponding to the height of the housing. When light is incident on them from the light-emitting parts 80 and 82 located at one end of the light guide, the entire light guide emits red light.

[0134] The door switch 84 detects the opening operation of the fire hydrant door 12. For example, it is installed on the fire hydrant door 12 and switches from off to on or on to off when the fire hydrant door 12 is opened, outputting a door open detection signal to the controller 78. The door switch 84 may also be installed on the fire extinguisher door 16, or on both the fire hydrant door 12 and the fire extinguisher door 16.

[0135] The transmitter 24 is installed on the electrically operated door 18 of the fire hydrant system 10. When operated by a user during a fire, a fire alarm signal is sent to the fire prevention receiving panel. The signal line is then branched to input the fire alarm signal to the controller 78.

[0136] The response lamp 25 is located on the electrically operated door 18 of the fire hydrant system 10. When a user operates the transmitter 24 and sends a fire alarm signal to the disaster prevention receiving panel, the disaster prevention receiving panel sends a response signal and the response lamp 25 lights up. The signal line for the response lamp 25 is then branched and the response signal is input to the controller 78.

[0137] The light emission control unit is equipped with a rechargeable battery power supply as its operating power source. Under normal circumstances, it is charged by AC100V supplied via a wiring cable to, for example, the red indicator light 22 of the electrical door 18. When the light emission units 80 and 82 are driven, the battery power supply is switched from charging mode to operation mode. This makes it possible to drive the light emission of the identification members 74 and 76 without increasing the capacity of the power supply equipment for the fire hydrant system 10. In addition to the battery power supply, a power generation mechanism that operates using the flow of water from the fire hose of the fire hydrant system 10 may also be provided as an operating power source.

[0138] The control operation of the light emission control unit shown in Figure 13(A) will be explained in more detail. When a fire breaks out and a user opens the fire hydrant door 12 to use the fire hydrant device 10, the door switch 84 is activated and a door open detection signal is input to the controller 78. Also, when a fire breaks out and a user operates the transmitter 24, a fire alarm signal is sent to the disaster prevention receiving panel and input to the controller 78.

[0139] When the controller 78 receives a door open detection signal from the door switch 84 or a fire alarm signal from the transmitter 24, it determines that the predetermined conditions for light emission drive have been met, and outputs a light emission drive signal to the light emission units 80 and 82 to drive the lights, causing the identification members 74 and 76 to light up, blink, or flash.

[0140] In this way, when a fire occurs, the fire hydrant device 10 operated by a user will activate the illumination of the identification members 74 and 76. In this case, the illumination of the identification members 74 and 76 will also be required for other fire hydrant devices 10 besides the one operated when the fire occurred.

[0141] In this embodiment, when the disaster prevention receiving panel receives a fire alarm signal from a fire hydrant device 10 that was operated when a fire occurs, it has a function to send a response signal to other fire hydrant devices other than the fire hydrant device 10 that sent the alarm. Therefore, when the controller 78 of the other fire hydrant devices 10 whose transmitter 24 has not been operated receives a response signal transmitted from the disaster prevention receiving panel, it drives the identification members 74 and 76 to light up, flash, or blink at multiple or all of the fire hydrant devices 10 that are arranged at 50-meter intervals along the monitoring corridor, making it possible to strongly recognize the presence of the housing corners protruding into the monitoring corridor for evacuees.

[0142] (d3. Other embodiments of the light emission control unit) Another embodiment of the light emission control unit shown in Figure 13(B) will be described in more detail. The light emission control unit of this embodiment utilizes a transmission unit located in the fire hydrant device 10. The configuration and functions of the light emission control unit are arbitrary, but for example, it consists of a transmission unit 90, a controller 78, light-emitting units 80, 82, a door switch 84, a transmitter 24, and a response lamp 25.

[0143] The transmission unit 90 is connected to the transmission path 92 from the disaster prevention receiving panel and transmits a signal containing a pre-configured unique self-address to the disaster prevention receiving panel, and also receives a signal containing its own address transmitted from the disaster prevention receiving panel.

[0144] A transmitter 24 is connected to the input side of the transmission unit 90, and a response lamp 25 is connected to the output side of the transmission unit 90. In addition, the pump start switch 64 and the pump start interlock switch 65 are connected in parallel with the transmitter 24 to the input side of the transmission unit 90. This is a known configuration. Furthermore, in this embodiment, a door switch 84 for detecting the opening of the fire hydrant door 12 is newly connected to the input side of the transmission unit 90.

[0145] The control operation of the light emission control unit shown in Figure 13(B) will be explained in more detail. When a fire breaks out, if a user operates the transmitter 24, a fire alarm signal is output to the transmission unit 90, and the transmission unit 90 transmits the fire alarm signal, which includes its own address, to the disaster prevention receiver panel via the transmission line 92. When the disaster prevention receiver panel receives the fire alarm signal via the transmission line 92, it identifies the fire hydrant device 10 from the address contained therein and performs a fire alarm operation, and transmits a response signal, which includes the address of the identified fire hydrant device 10, to the transmission line 92. When the transmission unit 90 of the fire hydrant device 10 determines that it has received a response signal that includes its own address, it lights up the response lamp 25 and also outputs the received response signal to the controller 78.

[0146] When the controller 78 receives a response signal from the transmission unit 90, it determines that the predetermined conditions for light emission drive have been met, and outputs a light emission drive signal to the light emission units 80 and 82 to drive the lights, causing the identification members 74 and 76 to light up, blink, or flash.

[0147] On the other hand, if a user opens the fire hydrant door 12 to use the fire hydrant device 10 without operating the transmitter 24, the door switch 84 is activated and a door open detection signal is output to the transmission unit 90. The transmission unit 90 then transmits the door open detection signal, including its own address, to the disaster prevention receiving panel via the transmission line 92.

[0148] When the fire alarm receiver receives a door open detection signal from the transmission line 92, it identifies the fire hydrant device 10 from the address contained therein, activates the fire alarm, and transmits a light emission control signal containing the address of the identified fire hydrant device 10 to the transmission line 92. When the transmission unit 90 of the fire hydrant device 10 determines that it has received the light emission control signal containing its own address, it outputs the received light emission control signal to the controller 78. When the controller 78 receives the light emission control signal from the transmission unit 90, it determines that the predetermined conditions for light emission drive have been met, outputs a light emission drive signal to the light emission units 80 and 82 to drive the lights, causing the identification members 74 and 76 to light up, blink, or flash.

[0149] [e. Variations of the present invention] Modifications of the fire hydrant device according to the present invention will now be described. In addition to the embodiments described above, the fire hydrant device of the present invention includes the following modifications.

[0150] (Wall-mounted fire hydrant system) The above embodiment takes as an example a fire hydrant device with a stationary structure in which the housing is attached and fixed to the upper part of a frame installed on the road surface of the guardian's walkway, close to the tunnel wall. However, it is not limited to this, and the same first embodiment in which a cover housing is placed on the side of the housing, the second embodiment in which a buffer member is placed at the corner of the housing, and the third embodiment in which an identification member is placed at or near the corner of the housing can also be applied to a wall-mounted fire hydrant device in which the housing is attached and fixed to the front part on the road side of a frame installed on the tunnel wall above the road surface of the guardian's walkway.

[0151] (Fire hydrant system) In the above embodiment, the fire extinguisher is housed in the second housing, but the fire extinguishing system may also be constructed in which the second housing does not have a fire extinguisher storage section, but instead has an electrical door and an auxiliary door at the front opening, and a terminal box is provided inside the housing.

[0152] (When the tunnel wall has a cross-section other than circular) Although the tunnel cross-sectional shape in the above embodiment is circular, if the tunnel cross-section is not circular, for example, a three-centered circle, the present invention can be applied by setting the horizontal line at the position with the widest horizontal width of the tunnel cross-sectional shape as the tunnel centerline SL1 in the above description.

[0153] (Structure of a fire hydrant device designed for a thinner design) In the fire hydrant device of the above embodiment, the width of the first and second housings is increased to compensate for the reduction in internal volume due to the thinning of the fire hydrant device. However, the height of the first and second housings may also be increased to compensate for the reduction in internal volume due to the thinning.

[0154] (others) Furthermore, the present invention includes appropriate modifications that do not impair its purpose and advantages, and is not limited by the numerical values ​​shown in the above embodiments. [Explanation of Symbols]
