Description

[Technical Field]

[0001] The present invention relates to a fire hydrant device in which a fire hydrant device, electrical equipment, a terminal box, and a fire extinguisher are arranged inside a housing, and a fire extinguisher box in which the electrical equipment, the terminal box, and the fire extinguisher are arranged. [Background technology]

[0002] Conventionally, in tunnels such as expressways and expressways, which are areas subject to firefighting, fire hydrant devices, which are a type of disaster prevention equipment storage device as shown in Figure 19, are generally installed along the length of the tunnel, for example, at intervals of 50 meters, by embedding boxes cut out from the wall of the tunnel's main body. Note that Figure 19(A) shows the front of the fire hydrant device, and Figure 19(B) shows a cross section of the fire hydrant device as seen from above. Note that Figure 19(B) is a cross section of the location hh indicated by the dashed line in Figure 19(A).

[0003] 19, the X, Y, and Z directions are perpendicular to each other. Specifically, as shown in FIGS. 19(A) and 19(B), when viewing the front face of the fire hydrant device from the front, 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. 1 to 18, which are embodiments of the present invention.

[0004] 19, in a conventional fire hydrant device 10, a fire hose 60 and valves (not shown) are stored as fire hydrant equipment in a fire hydrant storage section 15a within a housing 111a equipped with a fire hydrant door 12 and a maintenance door 14 that can be opened and closed, and two fire extinguishers 72, for example, are stored in a fire extinguisher storage section 15b within a housing 111b equipped with a fire extinguisher door 16 and an electrical door 180. The electrical door 180 is provided with, as electrical equipment, for example, a red indicator light 22 that is supplied with AC 100V, a transmitter 24 that is supplied with DC 48V, a response lamp 25, a telephone jack 28 (inside the housing of the electrical door), and in cold regions, a space heater that is further supplied with AC 200V is installed.

[0005] The power supplied to these electrical devices is supplied by a high-voltage wiring cable (high-voltage cable) and a low-voltage wiring cable (low-voltage cable) that are pulled from outside the fire hydrant device 10 to the fire hydrant storage section 15a side in the housing 111a, passing through one of the spaces in the fire hydrant storage section 15a, and connecting via a high-voltage terminal box 26a or a low-voltage terminal box 26b that is located in the fire extinguisher storage section 15b in the housing 111b.

[0006] However, if it is difficult to create an embedded section (recess) for the fire hydrant device in the wall of the tunnel body by cutting out a box or the like, the fire hydrant device must be installed in an exposed state above the road surface of the guard passage.

[0007] In such cases, a mounting structure has been proposed for wall-mounting a fire hydrant device on the wall of the tunnel body, and the mounting structure is composed of a main support part that is fixed to the wall of the tunnel body and a posture-maintaining member that maintains the posture of the fire hydrant device (Patent Document 2). [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-055073 [Patent Document 2] Japanese Patent Application Publication No. 2020-078429 [Patent Document 3] Japanese Patent Application Laid-Open No. 2016-59790 [Patent Document 4] Patent Publication No. 2021-87891 [Patent Document 5] Japanese Patent Application Laid-Open No. 2012-75608 [Patent Document 6] Japanese Patent Application Publication No. 11-123248 Summary of the Invention [Problem to be solved by the invention]

[0009] However, in the case of fire hydrant devices that are mounted on the wall of the tunnel body, the devices must be installed at a specified height above the road surface of the guard passage, so installing the fire hydrant device on the wall of the tunnel body is quite difficult, and many issues remain, such as the amount of labor and time required.

[0010] Therefore, in order to solve the problems of the wall-mounted fire hydrant device, it is possible to install the fire hydrant device in an exposed state on the road surface of the guard passage, which is easy to install, so-called a stationary structure. However, the installation of the fire hydrant device restricts the width (front-to-back) of the guard passage, so the remaining problem to solve is to make the width (front-to-back) of the fire hydrant device as thin as possible in order to ensure the width of the guard passage. Moreover, this problem is also present in the wall-mounted structure.

[0011] Incidentally, when making the fire hydrant device 10 thinner, the width of the fire hydrant device 10 is determined by the size of the fire extinguisher 72 stored in the fire hydrant device 10, and since the outer diameter of the fire extinguisher 72 is approximately 150 to 160 mm, for example, it is possible to make the width of the fire hydrant device 10 thinner to approximately 180 mm to 200 mm, while taking into consideration that the stored fire extinguisher 72 does not come into contact with the housing 111b.

[0012] Here, the size of the conventional fire hydrant device 10 is specified to unify the size of the box cut out against the wall surface of the tunnel body, and is, for example, approximately 1040 mm in length (up and down direction) x 1780 mm in width (left and right direction) x 300 mm in depth (front and back direction).By ensuring that the width of the fire hydrant device 10 is approximately 300 mm, there is enough space to store the fire extinguisher 72 in the fire extinguisher storage section 15b, and to place terminal boxes 26a, 26b on the rear surface of the housing 111b behind the fire extinguisher 72, and to wire the high-voltage cable and low-voltage cable connected to the terminal boxes 26a, 26b.

[0013] However, when making the fire hydrant device 10 thinner, the width of the fire hydrant device 10 decreases from 300 mm to approximately 180 mm to 200 mm, so the arrangement of the fire extinguisher 72, terminal boxes 26a, 26b and wiring cables in the fire extinguisher storage section 15b cannot be the same as in the conventional fire hydrant device 10, which is an obstacle to making the fire hydrant device 10 thinner.

[0014] The present invention aims to provide a fire hydrant device and a fire extinguisher box that can be made thin without being restricted by the fire hydrant device, electrical equipment, terminal box, fire extinguisher, etc. that are placed inside the housing. [Means for solving the problem]

[0015] (Fire hydrant device of the first invention) The present invention is a fire hydrant device in which a fire hydrant device, a terminal box, and a fire extinguisher are arranged in a housing, The housing is a first housing in which the fire hydrant device is disposed; a second housing in which electrical equipment and a terminal box are disposed; a third housing in which a fire extinguisher is disposed; It consists of The first, second, and third housings are arranged in a predetermined order along a predetermined direction such that the second housing is located at an end, and adjacent housings are connected to each other; A first door is provided on the front of the second housing corresponding to the position of the electrical equipment, and a second door is provided on the side of the second housing on which there is no adjacent housing corresponding to the position of the terminal box.

[0016] (Fire hydrant device of the second invention) The present invention is a fire hydrant device in which a fire hydrant device, a terminal box, and a fire extinguisher are arranged in a housing, The housing is a first housing in which the fire hydrant device, the electrical equipment, and the terminal box are arranged; a second housing in which a fire extinguisher is disposed; It consists of The first housing and the second housing are arranged along a predetermined direction and installed in a connected state, The inside of the first housing is divided into a fire hydrant storage section where the fire hydrant equipment is placed and an electrical equipment / terminal box storage section where the electrical equipment and terminal box are placed. The fire hydrant storage section and the electrical equipment / terminal box storage section are arranged in a predetermined order along a predetermined direction within the first housing, The second housing is located on the fire hydrant storage side of the first housing, A first door is provided on the front of the first housing corresponding to the position of the electrical equipment, and a second door is provided on the side of the first housing where the second housing is not present corresponding to the position of the terminal box.

[0017] (Fire hydrant device of the third invention) The present invention is a fire hydrant device in which a fire hydrant device, a terminal box, and a fire extinguisher are arranged in a housing, The housing is a first housing in which the fire hydrant device is disposed; a second housing in which electrical equipment, a terminal box, and a fire extinguisher are disposed; It consists of The first housing and the second housing are arranged along a predetermined direction and installed in a connected state, The inside of the second housing is divided into an electrical equipment / terminal box storage section where electrical equipment and terminal boxes are placed, and a fire extinguisher storage section where a fire extinguisher is placed. The electrical equipment / terminal box storage section and the fire extinguisher storage section are arranged in a predetermined order along a predetermined direction in the second housing, The first housing is located on the fire extinguisher storage side of the second housing, A first door is provided on the front of the second housing corresponding to the position of the electrical equipment, and a second door is provided on the side of the second housing on the side where the first housing is not present corresponding to the position of the terminal box.

[0018] (Layout of terminal box and electrical equipment) The electrical equipment and the terminal box are arranged in a predetermined direction or along the height direction in the installed state.

[0019] (Fire extinguisher box of the fourth invention) The present invention provides a fire extinguisher box in which an electrical device, a terminal box, and a fire extinguisher are arranged in a housing, The housing is a first housing in which electrical equipment and a terminal box are disposed; a second housing in which a fire extinguisher is disposed; It consists of The first housing and the second housing are arranged in a predetermined order along a predetermined direction and are installed in a connected state; A first door is provided on the front of the first housing corresponding to the position of the electrical equipment, and a second door is provided on the side of the first housing where the second housing is not present corresponding to the position of the terminal box.

[0020] Other features of the fire extinguisher box of the present invention are basically the same as those of the fire hydrant device described above, so a description thereof will be omitted. [Effects of the Invention]

[0021] (Effects of the fire hydrant device of the first invention) According to the fire hydrant device of the present invention, the housing is composed of a first housing in which the fire hydrant equipment is placed, a second housing in which the electrical equipment and terminal box are placed, and a third housing in which the fire extinguisher is placed, and these are arranged in a predetermined order along a predetermined direction, with adjacent housings being installed in a connected state.This makes it possible to make the fire hydrant device thinner without being restricted by the space required for placing the terminal box and the wiring space for the wiring cable connected to the terminal box, which were factors that made it difficult to make conventional fire hydrant devices thinner.

[0022] In addition, by placing the terminal box in the same housing as the electrical equipment to which the wiring cable is connected, it is possible to shorten the wiring length of the wiring cable compared to conventional fire hydrant devices in which the terminal box was placed behind the fire extinguisher, making it easier to route the wiring.

[0023] In addition, because the housings are divided according to the type of equipment to be installed, the configuration of the fire hydrant device can be flexibly changed to meet changes in requirements and specifications. Also, by configuring only the second and third housings, for example, the fire hydrant device can be converted into a fire extinguisher box, allowing for the sharing of equipment and leading to cost reductions. In addition, it is possible to flexibly respond at the work site to equipment changes due to tunnel grade upgrades and downgrades.

[0024] The above-described effects of the fire hydrant device of the first invention are also applicable to the fire hydrant devices of the second and third inventions.

[0025] (Effect of thinner fire hydrant devices) Furthermore, since the fire hydrant device can be made thinner without being restricted by the space required for placing the terminal box or the wiring space required for the wiring cable connected to the terminal box, it is possible to make the fire hydrant device thinner to a specified width corresponding to the outer diameter of the fire extinguisher, for example, approximately 180 mm to 200 mm, making it possible to make the device less than two-thirds thinner than conventional fire hydrant devices that are installed by cutting a box out of the wall of the tunnel body and embedding it in place.

[0026] (Effectiveness of fire hydrants installed on the road surface of guard passages in tunnels) In addition, the casing is installed at a predetermined height above the road surface of the guard passage that is installed along the interior wall of the tunnel, close to the wall of the tunnel, and each divided casing is installed in a direction along the wall of the tunnel.This, combined with the fact that the fire hydrant device is made thinner, makes it possible to install the fire hydrant device with minimal restrictions on the passage width of the guard passage.

[0027] (Effect of the door on terminal boxes and electrical equipment) In addition, because the first door corresponding to the location of the electrical equipment and the second door corresponding to the location of the terminal box are provided separately, it is only necessary to open the second door to perform wiring work or maintenance work on the terminal box, which makes it possible to improve the ease of installation and maintenance of the terminal box compared to conventional fire hydrant devices that are located behind the fire extinguisher and do not have a door for the terminal box. Furthermore, if the first door is also opened, the open area becomes wider, further improving the ease of installation and maintenance of the terminal box.

[0028] (Effect of terminal box and electrical equipment layout) Furthermore, since the electrical equipment and terminal box are arranged in a predetermined direction or along the height direction when installed, the electrical equipment and terminal box are arranged within the housing in a direction that does not affect the width of the fire hydrant device, and the space required for arranging the terminal box and the wiring space for the wiring cables connected to the terminal box are not constraints when making the fire hydrant device thinner.

[0029] The effects of the fire extinguisher box of the present invention are the same as those of the fire hydrant device described above, so a description thereof will be omitted. [Brief explanation of the drawings]

[0031] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a fire hydrant device and a fire extinguisher box according to the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following preferred embodiments.

[0032] [Basic concept of the embodiment] First, the basic concept of the embodiment will be described. The embodiment generally relates to a fire hydrant device in which a fire hydrant device, electrical equipment, a terminal box, and a fire extinguisher are arranged in a housing, and a fire extinguisher box in which the electrical equipment, the terminal box, and the fire extinguisher are arranged in a housing.

[0033] Here, a "fire hydrant device" is a type of emergency equipment that is installed in areas subject to fire extinguishing, such as tunnels on expressways and motorways, and is a housing installed in the area subject to fire extinguishing, in which fire hydrant equipment such as fire hoses, electrical equipment such as red indicator lights and transmitters on electrical doors, terminal boxes, and fire extinguishers are arranged, and the concept includes fire hydrant facilities in which fire hydrant devices are installed.

[0034] In addition, a "fire extinguisher box" is a type of emergency equipment that is installed in areas subject to fire extinguishing, such as tunnels on expressways and motorways, and is a housing installed in the area subject to fire extinguishing, with electrical equipment such as red indicator lights and transmitters on the electrical door, a terminal box, and a fire extinguisher placed inside.

[0035] In addition, the "placement" of the hydrant equipment, electrical equipment, terminal box and fire extinguisher relative to the hydrant device or fire extinguisher box is a concept that includes "storage."

[0036] Here, the housing of the fire hydrant device of the present invention is divided into three parts (first invention) or two parts (second invention and third invention).

[0037] The housing of the fire hydrant device of the first invention is composed of a first housing in which the fire hydrant equipment is arranged, a second housing in which the electrical equipment and terminal box are arranged, and a third housing in which the fire extinguisher is arranged, and the first housing, second housing, and third housing are arranged in a predetermined order along a predetermined direction, and are installed in a state in which adjacent housings are connected to each other.

[0038] Here, "fire hydrant equipment" refers to specified equipment including fire hoses and valves such as fire hydrant valves, "electrical equipment" refers to specified equipment including red indicator lights, transmitters, answering lights and telephone jacks, and "terminal box" refers to a storage box equipped with a terminal block for connecting wiring cables, etc. that are pulled into the housing from outside the fire hydrant device to the electrical equipment.

[0039] The "predetermined direction" refers to a direction that is approximately perpendicular to the width of the fire hydrant device, and is a direction that does not affect the width of the fire hydrant device when the housings are arranged in the predetermined direction. The "predetermined order" refers to the fact that the housings can be arranged in any order.

[0040] In addition, the housing of the fire hydrant device of the second invention is composed of a first housing in which the hydrant equipment, electrical equipment, and terminal box are arranged, and a second housing in which the fire extinguisher is arranged, and the first and second housings are arranged in a predetermined order along a predetermined direction and installed in a connected state, and the inside of the first housing is divided into a hydrant storage section in which the hydrant equipment is arranged and an electrical equipment / terminal box storage section in which the electrical equipment and terminal box are arranged, and the hydrant storage section and the electrical equipment / terminal box storage section are arranged in a predetermined order within the first housing along the predetermined direction.

[0041] In addition, the housing of the fire hydrant device of the third invention is composed of a first housing in which the fire hydrant device is arranged and a second housing in which the electrical equipment, terminal box, and fire extinguisher are arranged, the first housing and the second housing are arranged in a predetermined order along a predetermined direction and installed in a connected state, the inside of the second housing is divided into an electrical equipment / terminal box storage section in which the electrical equipment and terminal box are arranged and a fire extinguisher storage section in which the fire extinguisher is arranged, and the electrical equipment / terminal box storage section and the fire extinguisher storage section are arranged in a predetermined order within the second housing along the predetermined direction.

[0042] Here, "electrical equipment and terminal box storage" refers to the space inside the housing that includes the area where the electrical equipment and terminal box are located, and "fire extinguisher storage" refers to the space inside the housing that includes the area where the fire extinguisher is located. Also, "dividing the storage area" includes both physically dividing the space, such as with a partition board, and conceptually dividing the space without physically separating it.

[0043] The width of the housing may also be a predetermined width corresponding to the outer diameter of the fire extinguisher. Since the outer diameter of the fire extinguisher is about 150 to 160 mm, the "predetermined width corresponding to the outer diameter of the fire extinguisher" refers to a width that takes into consideration, for example, that the fire extinguisher does not come into contact with the housing, specifically a width of about 180 mm to 200 mm, and refers to the length in a direction that is not a height direction and is approximately perpendicular to the predetermined direction.

[0044] The housing may also be installed at a predetermined height above the road surface of a guard passageway that runs along the interior wall of a tunnel having a road, so as to be close to the wall of the tunnel. In this case, the predetermined direction is the direction along the wall of the tunnel. The "predetermined height" refers to a height at which the fire hydrant device can be installed close to the tunnel wall. For example, by installing a platform on the road surface of the guard passageway and installing the housing on the platform, the installation height of the fire hydrant device can be adjusted to the predetermined height.

[0045] The housing may also be provided with a first door corresponding to the location of the electrical equipment and a second door corresponding to the location of the terminal box. Here, the terms "first door" and "second door" are merely names used to distinguish between the door provided corresponding to the location of the electrical equipment and the door provided corresponding to the location of the terminal box, and do not refer to any difference in the door configuration. In other words, the "first door" and the "second door" may have the same configuration or different configurations.

[0046] Furthermore, the electrical equipment and the terminal box may be arranged in a predetermined direction in the housing or along the height direction in the installed state.

[0047] In addition, the housing of the fire extinguisher box of the fourth invention is composed of a first housing in which the electrical equipment and terminal box are arranged, and a second housing in which the fire extinguisher is arranged, and the first housing and second housing are arranged in a predetermined order along a predetermined direction and installed in a connected state.

[0048] A specific embodiment will be described below. In the specific embodiment shown below, a case will be described in which "the fire hydrant device is installed on a stand installed above the guard passage in the tunnel," "the terminal box" is "a terminal box for high voltage and low voltage," and "the predetermined one direction" is "the longitudinal direction of the tunnel."

[0050] [a. First embodiment of the fire hydrant device] A first embodiment of a fire hydrant device in which the housing is divided into three parts along the longitudinal direction of a tunnel will be described in more detail below. Figure 1 is an explanatory diagram showing the installation of a fire hydrant device according to the first embodiment inside a tunnel, with Figure 1(A) showing the installation of the fire hydrant device as seen from the cross section of the tunnel, and Figure 1(B) showing the installation of the fire hydrant device as seen toward the tunnel wall.

[0051] (a1. Overview of the fire hydrant device of the first embodiment) An overview of the fire hydrant device of the first embodiment will be described below. As shown in Fig. 1(B), the fire hydrant device 10 of the first embodiment is divided into a first housing 11a, a second housing 11b, and a third housing 11c, which are arranged from right to left, and adjacent housings are connected to each other.

[0052] Specifically, as shown in the cross-sectional view of the divided housing structure in Figure 2 viewed from above, the housing of the fire hydrant device 10 is divided into three parts: a first housing 11a, a second housing 11b, and a third housing 11c, and the right side of the second housing 11b is connected and fixed to the left side of the first housing 11a with a bolt 76 and a nut 78, and the right side of the third housing 11c is connected and fixed to the left side of the second housing 11b with a bolt 76 and a nut 78.

[0053] 1(B), 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 halves, with a forward-tilting fire hydrant door 12 that opens downward on hinges 12a located at the lower side of the door opening, and a maintenance door 14 that opens upward on hinges 14a located at the upper side of the door opening, and predetermined fire hydrant equipment including fire hoses and valves such as fire hydrant valves are stored in a fire hydrant storage section inside the first housing 11a.

[0054] Additionally, a decorative frame 13b is attached to the front of the second housing 11b. The door opening of the decorative frame 13b is divided into left and right halves, with a first door 18 on the right side that opens to the right via hinge 18a and a second door 20 on the left side that opens to the left via hinge 20a. The first door 18 functions as an electrical door and is provided with electrical equipment such as a red indicator light 22, a transmitter 24, and an answer lamp 25, and a telephone jack is provided inside the first door 18.

[0055] The red indicator light 22 is always lit, allowing the installation location of the fire hydrant device 10 to be confirmed from a distance. When a fire breaks out and the transmitter 24 is pressed to turn on the push button switch, a transmission signal is sent, which is received by the disaster prevention receiving panel in the electrical room and issues a fire alarm. 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.

[0056] A high-voltage terminal box 26a and a low-voltage terminal box 26b are arranged vertically on the rear surface of the second housing 11b opposite the second door 20. The high-voltage terminal box 26a uses a built-in terminal block to connect the high-voltage cable drawn from outside the fire hydrant device 10 to the red indicator light 22. The low-voltage terminal box 26b uses a built-in terminal block to connect the low-voltage cable drawn from outside the fire hydrant device 10 to the transmitter 24, the response lamp 25, a telephone jack, etc.

[0057] Additionally, a decorative frame 13c is attached to the front of the third housing 11c. A fire extinguisher door 16 that opens sideways to the left on hinges 16a is provided in the door opening of the decorative frame 13c, allowing for the storage of, for example, two fire extinguishers in a fire extinguisher storage section inside the third housing 11c. Additionally, a viewing window 17 is provided below the fire extinguisher door 16, allowing the presence or absence of a fire extinguisher to be confirmed from the outside.

[0058] (a2. Installation of fire hydrant equipment) The installation of fire hydrants in tunnels will be explained in more detail below. A road 36 is constructed in the longitudinal direction (left and right direction) of the tunnel below the cylindrical (circular cross section) tunnel body constructed using the shield tunneling method, and a guard passage 35 is constructed at a predetermined height above the road 36 below the tunnel wall 26 along the rear side of the road 36.

[0059] Since it is difficult to cut out boxes on the tunnel wall 26 when using the shield tunneling method to install the fire hydrant device 10, a mount 30 is installed close to the tunnel wall 26 on the road surface of the monitor's passage 35, and the first housing 11a, second housing 11b, and third housing 11c of the fire hydrant device 10, which are connected to each other, are attached and fixed to the mount 30. Here, the height H1 of the mount 30 is set so that the height from the road surface of the monitor's passage 35 to the transmitter 24 installed on the fire hydrant device 10 is within the legally specified range of 800 mm to 1500 mm.

[0060] The mount 30 of this embodiment is composed of a first mount 32 and a second mount 34. As shown in Fig. 1(A), the first mount 32 has a side shape that is an inverted trapezoid with the top side longer than the bottom side, and the rear side has a slope that faces diagonally downward along the curved shape of the tunnel wall surface 26. The second mount 34 is fixed on top of the first mount 32, and the first housing 11a, second housing 11b, and third housing 11c, which are connected to the fire hydrant device 10, are attached and fixed thereto.

[0061] (a3. Installation height and thinness of fire hydrant equipment) The installation height and thinning of the fire hydrant device will be explained in more detail below. In order to reduce the restriction on the passage width caused by the protrusion (projection) of the fire hydrant device 10, which is installed on the road surface of the guard passage 35 by the mount 30, from the tunnel wall surface 26, the installation height of the fire hydrant device 10 is optimized, and at the same time, the fire hydrant device 10 is made as thin as possible.

[0062] First, since the installation height of the fire hydrant device 10 is determined by the mounting base 30, optimization of the height H1 of the mounting base 30 will be described in more detail. Figure 3 shows a schematic diagram of the installation state of the fire hydrant device in a tunnel cross section. The tunnel wall 26 on which the fire hydrant device 10 is installed has a circular cross section, and in Figure 3(A), the height H1 of the mounting base 30 is set so that the horizontal housing center line SL2 passing through the center of the height direction of the fire hydrant device 10 installed on the guard passage 35 is as close as possible to the tunnel center line SL1 in the horizontal direction from the tunnel center (center of the circular cross section) P.

[0063] In this case, the closer the housing center line SL2 is to the tunnel center line SL1, the more the degree to which the fire hydrant device 10 protrudes from the tunnel wall surface 26 can be reduced.

[0064] 3(B) shows a case where the height H1 of the mount 30 is set so that the housing center line SL2 coincides with the tunnel center line SL1. In this case, the degree to which the fire hydrant device 10 protrudes from the tunnel wall surface 26 can be minimized. However, the height H1 of the mount 30 should be adjusted within the possible range, taking into account factors such as the ease of removing the fire extinguisher.

[0065] Next, a more detailed explanation will be given of how the fire hydrant device 10 can be made thinner. Of the devices housed in the fire hydrant device 10, the fire extinguisher housed in the third housing 11c has the largest size in the front-to-rear direction, and the fire hydrant device 10 can be made thinner as long as the width (front-to-rear direction) of the fire hydrant device is up to a size that allows the fire extinguisher to be housed in the third housing 11c, so the width of the fire hydrant device 10 is set to a predetermined width that corresponds to the outer diameter of the fire extinguisher housed in the third housing 11c.

[0066] The outer diameter of the fire extinguisher is about 150 to 160 mm, and if a gap is secured so that the stored fire extinguisher does not come into contact with the third housing 11c, the minimum width of the fire hydrant device 10 will be within a range of, for example, about 180 to 200 mm, and the width of the fire hydrant device 10 is set to a predetermined width within that range. In contrast, the width of a conventional fire hydrant device 10 that is installed by cutting a box out of the wall surface of a tunnel body and embedding it in place is about 300 mm, so the width of the fire hydrant device 10 of this embodiment can be made two-thirds of the conventional width, allowing the fire hydrant device 10 to be made thinner.

[0067] (a4. Configuration compatible with thinner fire hydrant devices) If the fire hydrant device 10 is thinned to a predetermined width in the range of approximately 180 to 200 mm corresponding to the outer diameter of the fire extinguisher, it becomes difficult to arrange the terminal boxes 26a, 26b on the rear surface of the housing behind the fire extinguisher storage section in which the fire extinguisher is stored, as in the conventional fire hydrant device 10 shown in Fig. 19. Therefore, in this embodiment, a first housing 11a, a second housing 11b, and a third housing 11c, which are divided into three parts in the longitudinal direction of the tunnel (left and right direction), are connected together, and the housing in which the electrical equipment is disposed (second housing 11b) and the housing in which the fire extinguisher is disposed (third housing 11c) are separated, and the terminal boxes 26a, 26b are arranged in the second housing 11b in which the electrical equipment is disposed, rather than in the third housing 11c in which the fire extinguisher is disposed.

[0068] [b. Fire hydrant system structure] The internal structure of the fire hydrant device, which is divided into three connected casings, a first casing 11a, a second casing 11b, and a third casing 11c, will be described in more detail with reference to FIGS.

[0069] (b1. Structure of the first housing) The structure of the first housing 11a will be described in more detail with reference to Fig. 4, which shows the internal structure of the fire hydrant device from the front with the hydrant door and maintenance door open, Fig. 5, which shows the internal structure of the fire hydrant device in a cross section viewed from above, and Fig. 6, which shows a cross section of the hose storage section of the first housing as viewed from the right side, where Fig. 5 is a cross section of the location aa indicated by the dashed line in Fig. 4, and Fig. 6 is a cross section of the location bb indicated by the dashed line in Fig. 4.

[0070] The interior of the first housing 11a, which serves as the hydrant storage section, is divided into a valve storage section 50a and a hose storage section 50b. A water supply pipe 48 is drawn into the valve storage section 50a from below through the stand 30 and connected to a hydrant 52. The water supply pipe 48 also branches downward, and at the end of the branch, a fire hydrant valve 54 and an automatic pressure regulating valve 56 are provided, and a fire hose 60 is subsequently connected. The hydrant valve 54 is opened and closed by a hydrant valve opening / closing lever 58. When the hydrant valve opening / closing lever 58 is opened or closed, the hydrant valve 54 is remotely opened and closed by a known wire link mechanism. When the hydrant valve opening / closing lever 58 is opened or closed, a pump start interlock switch provided on the operation box turns on and off. A pump start switch 64 for use by the fire brigade is provided to the upper right of the hydrant 52.

[0071] A hose storage frame 62 is provided in the hose storage section 50b, and a fire hose 60 is pulled in from below and stored in a state of being wound inward clockwise or counterclockwise. A nozzle 68 is attached to the tip of the fire hose 60 pulled out through a hose guide 66, and is detachably held in a nozzle holder 70. A cable rack 49 is provided above the hose storage section 50b to route the wiring cable pulled in from outside the first housing 11a to the second housing 11b side, and a cable passage opening is opened in the partition wall of the first housing 11a opposite the left end of the cable rack 49.

[0072] (b2. Structure of the second housing) The structure of the second housing 11b will be described in more detail with reference to Fig. 4, which shows the internal structure of the fire hydrant device from the front with the hydrant door and maintenance door open, Fig. 5, which shows the internal structure of the fire hydrant device in a cross section seen from above, Fig. 7, which shows a cross section of the electrical equipment storage section of the second housing as seen from the right side, and Fig. 8, which shows a cross section of the second housing as seen from above, Fig. 7 is a cross section of the portion cc indicated by the dashed line in Fig. 4, and Fig. 8 is a view showing the details of the second housing portion extracted from Fig. 5.

[0073] The interior of second housing 11b is divided into an electrical equipment storage section 50c and a terminal box storage section 50d. A first door 18 that opens sideways to the right on hinges 18a is disposed in the opening on the front of second housing 11b corresponding to electrical equipment storage section 50c. As shown in FIG. 7, first door 18 is equipped with, from top to bottom, a red indicator light 22, a transmitter 24, a telephone jack 28, and an answer lamp 25, and telephone jack 28 is disposed inside first door 18.

[0074] Here, of the electrical equipment, the red indicator light 22 has the largest size in the front-to-rear direction inside the second housing 11b, and its size is approximately 120 mm. Therefore, even if the fire hydrant device 10 is thinned to a predetermined width in the range of approximately 180 to 200 mm, each electrical equipment can be arranged while ensuring space for the wiring cable pulled in from the first housing 11a side.

[0075] In addition, a second door 20 that opens sideways to the left using a hinge 20a is arranged in the opening on the front of the second housing 11b corresponding to the terminal box storage section 50d, and as shown in Figure 7, terminal boxes 26a, 26b are arranged in the vertical direction on the rear surface of the housing inside the second housing 11b opposite the second door 20.

[0076] 8, the first door 18 is arranged so that its left end is bent inwardly of the housing 11b and in the closed position abuts against the surface (door mating surface) of the right end of the second door 20 facing the housing. A door holding structure (not shown) for holding the first door 18 and the second door 20 in the closed position is provided on the door mating surface. The door holding structure is arbitrary, and may include, for example, a fixing screw that can be operated from the outside of the second housing 11b provided on the door mating surface, or a magnetic member that is provided on the door mating surface and fixed to the second door 20 by magnetic attraction.

[0077] Furthermore, a wire passage opening 80 is formed in the partition wall that is connected to the first housing 11a on the right side of the second housing 11b, for pulling in the wiring cable that has been passed through the cable rack 49 of the first housing 11a. Furthermore, an opening 82 is formed in the partition wall that is connected to the third housing 11b on the left side of the second housing 11b, for use in, for example, opening the fire extinguisher door 16 of the third housing 11c and inserting a hand from the third housing 11c side to the second housing 11b side to release the door fastening of the first door 18 and the second door 20 from the inside of the second housing 11b, but this opening 82 does not have to be formed.

[0078] Here, the terminal boxes 26a, 26b arranged in the second housing 11b will be described in more detail. Figure 9 shows the terminal box 26a arranged in the second housing 11b, with Fig. 9(A) showing a top view of the terminal box 26a, Fig. 9(B) showing a front view of the terminal box 26a, and Fig. 9(C) showing a side view of the terminal box 26a. The same applies to the terminal box 26b.

[0079] Terminal box 26a is composed of box main body 260 and lid member 262, and its dimensions (length (top and bottom) x width (left and right) x depth (front and back)) when placed in second housing 11b are approximately 220 mm x 140 mm x 80 mm. Lid member 262 is disposed at the opening of box main body 260 so as to be able to open and close freely by hinge 264, and is fixed in the closed position by knob 268. When knob 268 is operated to release the fixation, lid member 262 is opened as shown by lid member 2620, allowing the work of connecting a wiring cable to terminal block 280a.

[0080] Furthermore, the cover member 262 is made of a transparent resin so that the terminal block 280a inside can be seen. A plurality of waterproof connectors 266, for example, two on each of the top and side surfaces, are arranged on the top and side surfaces of the box main body 260, ensuring waterproofness of the wiring cables inserted into the waterproof connectors 266. Also, a terminal block 280a on which a plurality of terminals are arranged is arranged on the box main body 260.

[0081] Even if the fire hydrant device 10 is thinned to a predetermined width in the range of approximately 180 to 200 mm, the depth (front to back) of the terminal boxes 26a, 26b is approximately 80 mm, so sufficient space is ensured within the second housing 11b to arrange the terminal boxes 26a, 26b. Furthermore, because the terminal boxes 26a, 26b are arranged in positions close to electrical equipment such as the red indicator light 22 arranged on the first door 18, short wiring can be used to connect the terminal boxes 26a, 26b to the electrical equipment.

[0082] Therefore, during the assembly of the second housing 11b at the factory, as shown in FIG. 8, the first door 18 and the second door 20 can be opened to the positions of the first door 180 and the second door 200 shown by the imaginary lines, thereby opening the front of the second housing 11b and facilitating the work of connecting the terminal blocks 26a, 26b and the electrical equipment arranged on the first door 18 with signal wires.

[0083] Furthermore, even when the fire hydrant device 10 is installed inside a tunnel, the front of the second housing 11b can be opened by releasing the door lock and opening the first door 18 and the second door 20 to the positions shown by the first door 180 and the second door 200 indicated by imaginary lines, as shown in FIG. 8, and the wiring cables drawn from the first housing 11a can be connected to the terminal boxes 26a and 26b, making it possible to easily perform the work without being hindered by the fire extinguisher that was previously stored in the same housing.

[0084] (b3. Structure of the third housing) The structure of the third housing 11c will be described in more detail. Reference is made to FIG. 4, which shows the internal structure of the fire hydrant device from the front with the hydrant door and maintenance door open, and FIG. 5, which shows the internal structure of the fire hydrant device in a cross section viewed from above. The interior of the third housing 11c forms a fire extinguisher storage section 50e, which has enough space to store two fire extinguishers 72 with an outer diameter of approximately 150 to 160 mm. As mentioned above, in order to make the fire hydrant device 10 thinner, the width of the fire hydrant device 10 is set to a predetermined width in the range of 180 to 200 mm, corresponding to the outer diameter of the fire extinguisher 72. This ensures gaps of approximately 15 to 25 mm in front and behind the stored fire extinguisher 72, allowing the fire extinguisher 72 to be stored within the third housing 11c without coming into contact with the third housing 11c.

[0085] (b4. Fire hydrant device cable wiring system) The cable wiring system of the electrical equipment arranged in the second housing 11b of the fire hydrant apparatus 10 will be described in more detail. As shown in Fig. 10, the first door 18 of the second housing 11b is provided with a red indicator light 22, a transmitter 24, a response lamp 25, and a telephone jack 28 as electrical equipment. The red indicator light 22 is connected to corresponding terminals on a terminal block 280a of the terminal box 26a, and the transmitter 24, the response lamp 25, and the telephone jack 28 are connected to corresponding terminals on a terminal block 280b of the terminal box 26b. Note that in Fig. 10, the positional relationship between the electrical equipment storage section 50c and the terminal box storage section 50d in the second housing 11b differs from the actual positions, but Fig. 10 shows the cable wiring system of the electrical equipment, not the actual positions and arrangement.

[0086] In addition, a pump start switch 64 and a pump start interlock switch 65 are provided in the valve storage section 50a in the first housing 11a of the fire hydrant device 10, and are connected to the terminal block 280b of the terminal box 26b provided in the second housing 11b by cable wiring through the cable rack 49.

[0087] A high-voltage cable 53 that supplies AC 100V power from the outside is pulled into the valve storage section 50a of the first housing 11a, and is pulled out to the second housing 11b side through the cable rack 49, and is connected to the terminal of the terminal block 280a of the terminal box 26a, and is then connected to the red indicator light 22.

[0088] In addition, a low-voltage cable 55 (which is a single multi-core cable but is represented in the cable wiring system of Figure 10 as a telephone cable 55a, a response lamp cable 55b, a transmitter cable 55c, and a switch cable 55d), which is a multi-core cable that supplies DC 48V power from the outside, is pulled into the valve storage section 50a of the first housing 11a, is pulled out to the second housing 11b side through the cable rack 49, and is connected to the terminals of the terminal block 280b of the terminal box 26b, and is thereby connected to the telephone jack 28, response lamp 25, transmitter 24, and pump start switch 64 and pump start interlock switch 65 provided in the valve storage section 50a on the first door 18.

[0089] 10, the pump start switch 64 and the pump start interlocking switch 65 of the valve storage section 50a are connected to the terminals of the terminal block 280b of the terminal box 26b as a parallel circuit in which the wiring of the pump start interlocking switch 65 is connected to the terminal part of the pump start switch 64. Also, the terminal of the terminal block 280b of the terminal box 26b to which the wiring of the pump start switch 64 and the pump start interlocking switch 65 are connected is connected to the terminal to which the wiring of the transmitter 24 is connected via a crossover wiring, so that the wiring of the pump start switch 64 and the pump start interlocking switch 65 is connected to the wiring of the transmitter 24.

[0090] (b5. Advantages of the fire hydrant device of the first embodiment) Thus, in the first embodiment of the fire hydrant device 10, 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, and the housing of the fire hydrant device 10 is divided into a first housing 11a in which fire hydrant equipment such as the fire hose 60 and valves are arranged, a second housing 11b in which electrical equipment such as the red indicator light 22 and transmitter 24 and terminal boxes 26a, 26b are arranged, and a third housing 11c in which the fire extinguisher 72 is arranged, and the adjacent housings are installed by connecting them together.

[0091] Therefore, since the installation space for the terminal boxes 26a, 26b is secured by the second housing 11b, the width of the fire hydrant device 10 can be reduced to less than two-thirds of the width of a conventional fire hydrant device 10 that is installed by cutting a box out of the wall of the tunnel body and embedding it in place, and this makes it possible to install the fire hydrant device 10 above the monitor's passage 35 inside the tunnel while minimizing restrictions on the passage width of the monitor's passage 35.

[0092] [c. First embodiment of the fire hydrant device in which the order of the housings is changed] An embodiment of a fire hydrant device in which the arrangement order of the three divided housings in the longitudinal direction of the tunnel is changed will be described in more detail. The fire hydrant device 10 of the first embodiment is divided into a first housing 11a, a second housing 11b, and a third housing 11c from right to left and arranged, and adjacent housings are connected to each other for installation. However, the arrangement order of the first housing 11a, the second housing 11b, and the third housing 11c can be changed as necessary.

[0093] The first housing 11a, the second housing 11b, and the third housing 11c may be arranged in any order, but Fig. 12 shows an example of a fire hydrant device 10 in which the order of the housings is changed. The fire hydrant device 10 in Fig. 12 has the order of the second housing 11b and the third housing 11c reversed, with the third housing 11c connected to the left side of the first housing 11a, and the second housing 11b connected to the left side of the third housing 11c.

[0094] In this case, the structures of the first housing 11a, the second housing 11b, and the third housing 11c are basically the same as the structures shown in Figures 1 to 8, but differ in that the left side surface of the second housing 11b, which is located at the left end, is a closed surface, and the connecting surface between the third housing 11c and the second housing 11b is, for example, an open surface to allow wiring cables to pass through.

[0095] In addition, an electrical door corresponding to the first door 18 may be provided as a single door on the front of the second housing 11b located at the left end, and a door corresponding to the second door 20 may be provided on the left side of the second housing 11b.

[0096] [d. Fire extinguisher box embodiment] The first embodiment of the fire extinguisher box will be described in more detail. In this embodiment of the fire extinguisher box, the second housing 11b of the first embodiment of the fire hydrant device 10 is the first housing 110a, and the third housing 11c is the second housing 110b. As shown in the front view of the fire extinguisher box in Figure 13(A) and the cross-sectional view of the internal structure of the fire extinguisher box seen from above in Figure 13(B), the first housing 110a and the second housing 110b are divided into two parts and arranged connected to each other from right to left. Note that Figure 13(B) is a cross section of the part dd indicated by the dashed line in Figure 13(A).

[0097] The embodiment of the fire extinguisher box 100 has a configuration in which the first housing 11a is removed from the first embodiment of the fire hydrant device 10, and the first housing 110a is basically the same as the second housing 11b, and the second housing 110b is basically the same as the third housing 11c.

[0098] Therefore, the fire extinguisher box 100 can be thinned to a predetermined width in the range of 180 to 200 mm corresponding to the outer diameter of the fire extinguisher 72, while ensuring space for placing the terminal boxes 26a and 26b using the first housing 110a, making it possible to install the fire extinguisher box 100 on the guard passage 35 inside the tunnel while minimizing restrictions on the passage width of the guard passage 35.

[0099] Also in this embodiment, the order of the first housing 110a and the second housing 110b can be changed as desired, and the second housing 110b may be connected to the right side of the first housing 110a.

[0100] [e. Second embodiment of the fire hydrant device] The second embodiment of the fire hydrant device will be described in more detail. In the second embodiment of the fire hydrant device 10, the first housing 11a and the second housing 11b of the first embodiment of the fire hydrant device 10 are combined into a single housing as the first housing 112a, and the third housing 11c is combined into the second housing 112b.

[0101] In the second embodiment of the fire hydrant device 10, as shown in the cross-sectional top view of the internal structure of the fire hydrant device in Fig. 14(A), the fire hydrant device is divided into two, first housing 112a and second housing 112b, which are connected and installed from right to left. Specifically, as shown in the cross-sectional top view of the divided housing structure of the fire hydrant device in Fig. 14(B), the housing of the fire hydrant device 10 is divided into two, first housing 112a and second housing 112b, and the right side of the second housing 112b is connected and fixed to the left side of the first housing 112a with bolts 76 and nuts 78. Note that Fig. 14(A) is a cross-section of the fire hydrant device 10 in the second embodiment at the location aa indicated by the dashed line in Fig. 4, which shows the front of the fire hydrant device 10 in the first embodiment.

[0102] The interior of the first housing 112a is divided into, from the right side, a valve storage section 50a, a hose storage section 50b, an electrical equipment storage section 50c, and a terminal box storage section 50d, and a partition plate 84 is disposed between the hose storage section 50b and the electrical equipment storage section 50c. The partition plate 84 also has a wire passage opening formed therein for drawing the wiring cable that is drawn into the valve storage section 50a from the outside and passed through the valve storage section 50a and the hose storage section 50b toward the electrical equipment storage section 50c.

[0103] The structures of the valve storage section 50a, hose storage section 50b, electrical equipment storage section 50c and terminal box storage section 50d of the first housing 112a, the equipment to be placed therein, and the doors provided corresponding to each storage section are basically the same as those of the first embodiment of the fire hydrant device 10.

[0104] The inside of the second housing 112b is a fire extinguisher storage section 50e, and the structure of the fire extinguisher storage section 50e, the devices arranged therein, and the doors provided therein are basically the same as those of the fire hydrant device 10 in the first embodiment.

[0105] In addition, a cable rack is provided in the hose storage section 50b for passing wiring cables through, and each of the connecting surfaces between the first housing 112a and the second housing 112b may have an opening formed therein that can be used to, for example, open the fire extinguisher door 16 of the second housing 112b and reach into the terminal box storage section 50d of the first housing 112a from the second housing 112b side to release the door fastening of the first door 18 and the second door 20 from the inside of the first housing 112a, but this is not shown in the illustration.

[0106] Furthermore, in the second embodiment of the fire hydrant device 10, similar to the first embodiment of the fire hydrant device 10, the terminal box storage section 50d ensures space for arranging the terminal boxes 26a, 26b, and the width of the fire hydrant device 10 can be thinned to a predetermined width in the range of 180 to 200 mm that corresponds to the outer diameter of the fire extinguisher 72, making it possible to install the fire hydrant device 10 above the monitor passage 35 inside a tunnel while minimizing restrictions on the passage width of the monitor passage 35.

[0107] Also in this embodiment, the order of first housing 112a and second housing 112b can be changed as desired, and second housing 112b may be connected to the right of first housing 112a.

[0108] [f. Third embodiment of the fire hydrant device] The third embodiment of the fire hydrant device will be described in more detail. In the third embodiment of the fire hydrant device 10, the first housing 11a of the first embodiment of the fire hydrant device 10 is used as a first housing 114a, and the second housing 11b and the third housing 11c are used as a second housing 114b to form a single housing.

[0109] In the third embodiment of the fire hydrant device 10, as shown in the cross-sectional top view of the internal structure of the fire hydrant device in Fig. 15(A), the fire hydrant device is divided into two, a first housing 114a and a second housing 114b, which are connected and installed from right to left. Specifically, as shown in the cross-sectional top view of the divided housing structure of the fire hydrant device in Fig. 15(B), the housing of the fire hydrant device 10 is divided into two, a first housing 114a and a second housing 114b, and the right side of the second housing 114b is connected and fixed to the left side of the first housing 114a with a bolt 76 and a nut 78. Note that Fig. 15(A) is a cross-section of the fire hydrant device 10 in the third embodiment at the location aa indicated by the dashed line in Fig. 4, which shows the front of the fire hydrant device 10 in the first embodiment.

[0110] The interior of the first housing 114a is divided from the right side into a valve storage section 50a and a hose storage section 50b, and the structures of the valve storage section 50a and the hose storage section 50b, the equipment placed therein, and the doors provided corresponding to the storage sections are basically the same as those of the first embodiment of the fire hydrant device 10.

[0111] The interior of the second housing 114b is divided from the right side into an electrical equipment storage section 50c, a terminal box storage section 50d, and a fire extinguisher storage section 50e, and a partition plate 84 is arranged between the terminal box storage section 50d and the fire extinguisher storage section 50e.

[0112] The structures of the electrical equipment storage section 50c, the terminal box storage section 50d, and the fire extinguisher storage section 50e of the second housing 114b, the equipment to be placed therein, and the doors provided corresponding to each storage section are basically the same as those of the first embodiment of the fire hydrant device 10.

[0113] In addition, each of the connecting surfaces between the first housing 114a and the second housing 114b is formed with a wire passage port for pulling in the wiring cable that has passed through the first housing 114a from the outside to the second housing 114b side, and the hose storage section 50b is provided with a cable rack for inserting the wiring cable, and the partition plate 84 that separates the terminal box storage section 50d and the fire extinguisher storage section 50e of the second housing 114b may be formed with an opening that can be used to open the fire extinguisher door 16, reach into the electrical equipment storage section 50d from the fire extinguisher storage section 50e, and release the door locking of the first door 18 and the second door 20 from the inside of the second housing 114b, but this is not shown in the illustration.

[0119] Here, the second housing 11b of this embodiment will be described in more detail with reference to Figures 16 to 18. Figure 17 shows a cross section of the second housing of the fire hydrant device of Figure 16 as seen from the right side, Figure 18(A) shows a cross section of the portion where the first door is arranged as seen from above, and Figure 18(B) shows a cross section of the portion where the second door is arranged as seen from above. Note that Figure 17 is a cross section of the portion ee indicated by the dashed line in Figure 16, Figure 18(A) is a cross section of the portion ff indicated by the dashed line in Figure 17, and Figure 18(B) is a cross section of the portion gg indicated by the dashed line in Figure 17.

[0120] The first door 18, located above the front opening of the second housing 11b, has a red indicator light 22 and a telephone jack 28 (inside the door) arranged on the left and right sides, and below that a transmitter 24 and an answer lamp 25 arranged on the left and right sides, and the first door 18 is supported at two points, top and bottom, by hinges 18a at the right end so that it can open sideways to the right as first door 180 shown in imaginary lines.

[0121] In addition, the second door 20, which is located below the front opening of the second housing 11b, is supported at two points above and below the right end by hinges 20a so that it can open sideways to the right as shown by the imaginary line as the second door 200.

[0122] Terminal boxes 26a and 26b are arranged on the rear surface of second housing 11b opposite second door 20. As shown in Fig. 16, for example, terminal boxes 26a and 26b are arranged at positions offset from each other in the vertical and horizontal directions, thereby ensuring sufficient wiring space around each of terminal boxes 26a and 26b.

[0123] Furthermore, the first door 18 and the second door 20 are provided with a door holding structure (not shown) for holding them in the closed position. The door holding structure is arbitrary, but for example, a fixing screw that can be operated from the outside of the second housing 11b may be provided on the contact surface with the front opening edge of the second housing 11b, or a magnetic member may be provided on the door side and fixed by magnetic attraction to the front opening edge of the second housing 11b.

[0124] [h. Modifications of the present invention] In addition to the above-described embodiment, the fire hydrant device and the fire extinguisher box of the present invention include the following modifications.

[0125] (If the tunnel wall has a cross section other than a circular cross section) In the above embodiment, the tunnel cross-sectional shape is circular, but if the tunnel cross-section is other than circular, such as a tricentric circle, the present invention can be applied by taking the horizontal line at the position where the horizontal width of the tunnel cross-sectional shape is widest as the tunnel center line SL1 in the above explanation.

[0126] (Layout of electrical equipment and terminal box) In the above-described embodiments of the fire hydrant device and fire extinguisher box, the electrical equipment and terminal box are arranged in the left-right or up-down direction, but the arrangement does not necessarily have to be as shown in the embodiment, and any appropriate arrangement may be used as long as it ensures that there is sufficient space for the terminal box and electrical equipment and for wiring cables, and does not hinder the thinning of the fire hydrant device.
