Description

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, terminal box, and fire extinguisher are arranged.

Conventionally, in tunnels on expressways, motorways, and other areas subject to firefighting, fire hydrant devices, a type of disaster prevention equipment storage device as shown in FIG. 19, are typically installed in the longitudinal direction of the tunnel, for example, at intervals of 50 meters, embedded into the walls of the tunnel body. Note that FIG. 19(A) shows the front of the fire hydrant device, and FIG. 19(B) shows a cross section of the fire hydrant device as seen from above. Note that FIG. 19(B) is a cross section of the location h-h indicated by the dashed line in FIG. 19(A).

In the explanation of FIG. 19, the X-Y-Z directions are mutually orthogonal directions; specifically, as shown in FIG. 19(A) and (B), when looking at the front 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. Also, the +X side in the X direction is the right side, the -X side is the left side, the +Y side in the Y direction is the top side, the -Y side is the bottom side, and the +Z side in the Z direction is the front side, and the -Z side is the rear side. This also applies to FIG. 1 to FIG. 18, which are embodiments of the present invention.

As shown in FIG. 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 in a housing 111a equipped with a fire hydrant door 12 and a maintenance door 14 that can be opened and closed. Also, for example, two fire extinguishers 72 are stored in a fire extinguisher storage section 15b in a housing 111b equipped with a fire extinguisher door 16 and an electrical door 180. The electrical door 180 is provided with, for example, a red indicator light 22 supplied with AC 100V, a transmitter 24 supplied with DC 48V, a response lamp 25, a telephone jack 28 (inside the housing of the electrical door), and the like as electrical equipment, and in cold regions, a space heater supplied with AC 200V is also installed.

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 the outside of 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.

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 other means, the fire hydrant device must be installed in an exposed state above the road surface of the guard passage.

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

JP 2016-055073 A JP 2020-078429 A

However, in the case of fire hydrant devices that are mounted on the walls of the tunnel structure, they must be installed at a specified height above the road surface of the guard passage, making installation of the fire hydrant device on the walls of the tunnel structure extremely difficult, and many issues remain, such as the labor and time required.

Therefore, in order to solve the problems with this wall-mounted fire hydrant device, it is possible to install the device in an exposed state on the road surface of the monitor's passage, making it a so-called freestanding structure. However, the installation of the fire hydrant device restricts the width (front-to-back direction) of the monitor's passage, and the remaining problem to be solved is to make the width (front-to-back direction) of the fire hydrant device as thin as possible in order to ensure the passage width of the monitor's passage. Moreover, this problem is similar for wall-mounted structures.

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.

The size of the conventional fire hydrant device 10 is specified to standardize the size of the box cut out from the wall of the tunnel body, for example, approximately 1040 mm long (up and down) x 1780 mm wide (left and right) x 300 mm deep (front and back). By ensuring that the width of the fire hydrant device 10 is approximately 300 mm, sufficient space is ensured to store the fire extinguisher 72 in the fire extinguisher storage section 15b, place the terminal boxes 26a, 26b on the rear surface of the housing 111b behind the fire extinguisher 72, and wire the high-voltage cable and low-voltage cable connected to the terminal boxes 26a, 26b.

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

The present invention aims to provide a fire hydrant device and 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.

(Fire hydrant installed on the road surface of the guard passage in the tunnel)
the housing is installed at a predetermined height above a road surface of a monitor passage provided along an inner wall surface of a tunnel having a road so as to be close to the wall surface of the tunnel;
The predetermined direction is a direction along the wall of the tunnel.

(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.

(Fire extinguisher box according to the fourth invention)
The present invention relates to a fire extinguisher box in which an electrical device, a terminal box, and a fire extinguisher are arranged inside a housing,
The housing is
a first housing in which an electrical device and a terminal box are disposed;
a second housing in which a fire extinguisher is disposed;
It is composed of
The first and second housings are arranged in a predetermined order along a predetermined direction and are installed in a connected state.

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 their explanation will be omitted.

(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 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 these are arranged in a predetermined order along a predetermined direction, and adjacent housings are installed in a connected state.This makes it possible to make the fire hydrant device thinner without being restricted by the space required for arranging 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.

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.

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

The effects of the fire hydrant device of the first invention described above are also the same for the fire hydrant devices of the second and third inventions.

(Effect of a thinner fire hydrant device)
In addition, since the fire hydrant device can be made thinner without being restricted by the space required for placing the terminal box and 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 fire hydrant 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.

(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 monitor's passageway 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 thin, makes it possible to install the fire hydrant device with minimal restrictions on the passageway width of the monitor's passageway.

(Effect of doors on terminal boxes and electrical equipment)
In addition, since the first door corresponding to the position of the electrical equipment and the second door corresponding to the position of the terminal box are separately provided, the second door only needs to be opened for wiring and 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. Also, if the first door is also opened, the open area becomes wider, which makes it possible to further improve the ease of installation and maintenance of the terminal box.

(Effect of the layout of terminal boxes and electrical equipment)
In addition, since the electrical equipment and terminal box are arranged in a specific 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 placing the terminal box and the wiring space for the wiring cables connected to the terminal box are not constraints on making the fire hydrant device thinner.

The effects of the fire extinguisher box of the present invention are the same as those of the fire hydrant device described above, so we will not explain them here.

Below, an embodiment of a fire hydrant device and a fire extinguisher box according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the following embodiment.

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

Here, a "fire hydrant device" is a type of emergency equipment installed in areas subject to firefighting, such as tunnels on expressways and motorways, and is a housing installed in the area subject to firefighting that is equipped with fire hydrant equipment such as a fire hose, electrical equipment such as a red indicator light and a transmitter on an electrical door, a terminal box, and a fire extinguisher. The concept includes fire hydrant facilities in which a fire hydrant device is installed.

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 installed inside.

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

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

The housing of the fire hydrant device of the first invention is composed of a first housing in which the fire hydrant device 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.

Here, "fire hydrant equipment" refers to specific equipment including fire hoses and valves such as fire hydrant valves, "electrical equipment" refers to specific equipment including red indicator lights, transmitters, answer lights and telephone jacks, and "terminal boxes" refers to storage boxes equipped with terminal blocks for connecting wiring cables, etc., pulled into the housing from the outside of the fire hydrant device to the electrical equipment.

The "predetermined direction" refers to a direction that is approximately perpendicular to the direction that defines the width of the fire hydrant device, and is a direction that does not affect the width of the fire hydrant device when each housing is arranged in the predetermined direction. The "predetermined order" refers to the fact that the order in which each housing is arranged is arbitrary.

The housing of the fire hydrant device of the second invention is composed of a first housing in which the fire hydrant device, electrical equipment, and terminal box are arranged, and a second housing in which the fire extinguisher is 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 first housing is divided into a fire hydrant storage section in which the fire hydrant device is arranged, and an electrical equipment/terminal box storage section in which the electrical equipment and terminal box are arranged, and the fire 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.

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.

Here, "electrical equipment and terminal box storage section" refers to the space including the area inside the housing where the electrical equipment and terminal box are placed, and "fire extinguisher storage section" refers to the space including the area inside the housing where the fire extinguisher is placed. Also, "dividing the storage section" includes both physically dividing the space, such as with a partition board, and conceptually dividing the space without being physically separated.

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 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 the height direction and is approximately perpendicular to the predetermined direction.

The housing may be installed at a predetermined height above the road surface of a monitor's passageway that is provided along the inner 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 a direction along the wall of the tunnel. The "predetermined height" is a height at which the fire hydrant device can be installed close to the tunnel wall; for example, a stand is installed on the road surface of the monitor's passageway, and the housing is installed on the stand, so that the installation height of the fire hydrant device can be adjusted to the predetermined height.

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

The electrical equipment and terminal box may also be arranged in a specific direction in the housing or along the height direction when installed.

The housing of the fire extinguisher box according to 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.

A specific embodiment will be described below. In the specific embodiment shown below, the fire hydrant device is installed on a stand installed above the guard passage inside the tunnel, the terminal box is a high-voltage and low-voltage terminal box, and the specified direction is the longitudinal direction of the tunnel.

[a. First embodiment of the fire hydrant device]
A more detailed description will be given of a first embodiment of a fire hydrant device in which the housing is divided into three parts in the longitudinal direction of a tunnel. Fig. 1 is an explanatory diagram showing the installation state of the fire hydrant device according to the first embodiment in a tunnel, in which Fig. 1(A) shows the installation state of the fire hydrant device as seen from the cross section of the tunnel, and Fig. 1(B) shows the installation state of the fire hydrant device as seen from the direction of the tunnel wall.

(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. 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.

Specifically, as shown in the cross-sectional top view of the divided housing structure in Figure 2, 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. 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.

As shown in FIG. 1B, 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 parts, with a forward-tilting fire hydrant door 12 that opens downwards on hinges 12a located at the lower part of the door opening, and a maintenance door 14 that opens upwards on hinges 14a located at the upper part of the door opening. A fire hydrant storage section inside the first housing 11a stores a fire hose and a specified fire hydrant device including valves such as a fire hydrant valve.

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 sideways to the right via a hinge 18a, and a second door 20 on the left side that opens sideways to the left via a 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 a response lamp 25, and a telephone jack is provided on the inside of the first door 18.

The red indicator light 22 is always lit, allowing the 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.

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 pulled in 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 pulled in from outside the fire hydrant device 10 to the transmitter 24, response light 25, telephone jack, etc.

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 at the door opening of the decorative frame 13c, allowing two fire extinguishers, for example, to be stored in the fire extinguisher storage section inside the third housing 11c. A viewing window 17 is also provided below the fire extinguisher door 16, making it possible to check from the outside whether a fire extinguisher is present.

(a2. Installation of fire hydrant devices)
The installation of fire hydrants in tunnels will now be described in more detail. 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 by the shield 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.

Because it is difficult to cut out a box from the tunnel wall 26 when using the shield construction method to install the fire hydrant device 10, a stand 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 stand 30. Here, the height H1 of the stand 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.

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 is an inclined surface 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 connected to the fire hydrant device 10 are attached and fixed thereto.

(a3. Installation height and thinness of fire hydrant equipment)
The installation height and thinning of the fire hydrant device will be described in more detail. In order to reduce the restriction on the passage width caused by the protrusion (projection) of the fire hydrant device 10 installed on the road surface of the monitor passage 35 by the stand 30 from the tunnel wall surface 26, the installation height of the fire hydrant device 10 is optimized and the fire hydrant device 10 is made as thin as possible.

First, since the installation height of the fire hydrant device 10 is determined by the mounting base 30, the 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 monitor passage 35 is as close as possible to the horizontal tunnel center line SL1 from the tunnel center (center of the circular cross section) P.

In this case, the closer the housing center line SL2 is to the tunnel center line SL1, the less the fire hydrant device 10 protrudes from the tunnel wall surface 26.

Figure 3 (B) shows a case where the height H1 of the mounting 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 mounting 30 is adjusted to the extent possible, taking into account the removal of the fire extinguisher, etc.

Next, the thinning of the fire hydrant device 10 will be described in more detail. The fire extinguisher stored in the third housing 11c is the device that has the largest size in the front-to-rear direction among the devices stored in the fire hydrant device 10, and the fire hydrant device 10 can be thinned 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 stored in the third housing 11c. Therefore, the width of the fire hydrant device 10 is set to a predetermined width that corresponds to the outer diameter of the fire extinguisher stored in the third housing 11c.

The outer diameter of the fire extinguisher is about 150 to 160 mm, and if a gap is provided 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 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 2/3 or less of the conventional width, allowing the fire hydrant device 10 to be made thinner.

(a4. Configuration corresponding to thinning of fire hydrant device)
When the fire hydrant device 10 is thinned to a predetermined width in the range of about 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 on the rear side of 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, the first housing 11a, the second housing 11b, and the third housing 11c, which are divided into three parts in the tunnel longitudinal direction (left and right direction), are connected, and the housing (second housing 11b) in which the electrical equipment is arranged and the housing (third housing 11c) in which the fire extinguisher is arranged are separated, and the terminal boxes 26a, 26b are arranged in the second housing 11b in which the electrical equipment is arranged, rather than in the third housing 11c in which the fire extinguisher is arranged.

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

(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 fire hydrant door and the maintenance door open, Fig. 5, which shows the internal structure of the fire hydrant device in a cross section seen from above, and Fig. 6, which shows the cross section of the hose storage section of the first housing from the right side, Fig. 5 is a cross section taken along the line a-a indicated by the dashed line in Fig. 4, and Fig. 6 is a cross section taken along the line b-b indicated by the dashed line in Fig. 4.

The inside of the first housing 11a, which serves as the fire 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 water supply hydrant 52. The water supply pipe 48 also branches downward, and a fire hydrant valve 54 and an automatic pressure adjustment valve 56 are provided at the branch end, followed by a fire hose 60. The fire hydrant valve 54 is opened and closed by a fire hydrant valve opening and closing lever 58, and when the fire hydrant valve opening and closing lever 58 is opened and closed, the fire hydrant valve 54 is opened and closed remotely by a known wire link mechanism. When the fire hydrant valve opening and closing lever 58 is opened and closed, a pump start interlock switch provided on the operation box is turned on and off. In addition, a pump start switch 64 used by the fire brigade is provided at the upper right of the water supply hydrant 52.

A hose storage frame 62 is provided in the hose storage section 50b, and the fire hose 60, which is pulled in from below, is stored in a clockwise or counterclockwise inward coiled state. A nozzle 68 is attached to the end of the fire hose 60, which is pulled out through a hose guide 66, and is detachably held by a nozzle holder 70. A cable rack 49 is provided above the hose storage section 50b to pass the wiring cable pulled in from outside the first housing 11a to the second housing 11b, 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.

(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 fire hydrant door and the 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 seen from the right side, and Fig. 8, which shows a cross section of the second housing seen from above, Fig. 7 is a cross section of the portion c-c shown by the dashed line in Fig. 4, and Fig. 8 is a detailed view of the second housing portion of Fig. 5.

The interior of the 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 a hinge 18a is located in the opening on the front of the second housing 11b corresponding to the electrical equipment storage section 50c. The first door 18 is equipped with a red indicator light 22, a transmitter 24, a telephone jack 28, and an answer lamp 25, arranged in this order from top to bottom as shown in FIG. 7, and the telephone jack 28 is located inside the first door 18.

Of the electrical equipment, the red indicator light 22 has the largest front-to-rear size 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 placed while still ensuring space for the wiring cable pulled in from the first housing 11a.

A second door 20 that opens sideways to the left on a hinge 20a is disposed in the opening on the front of the second housing 11b corresponding to the terminal box storage section 50d, and as shown in FIG. 7, terminal boxes 26a, 26b are disposed vertically on the rear surface of the housing inside the second housing 11b opposite the second door 20.

8, the first door 18 is arranged such that the left end portion is bent inwardly of the housing 11b and abuts against the surface (door mating surface) facing the housing side surface of the right end portion of the second door 20 in the closed position. 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 for example, a fixing screw operable from the outside of the second housing 11b may be provided on the door mating surface, or a magnet member may be provided on the door mating surface to fix the second door 20 by magnetic attraction.

Moreover, a wire passage opening 80 for pulling in the wiring cable inserted into the cable rack 49 of the first housing 11a is formed in the partition wall connected to the first housing 11a on the right side of the second housing 11b. Moreover, an opening 82 is formed in the partition wall connected to the third housing 11b on the left side of the second housing 11b to open the fire extinguisher door 16 of the third housing 11c and insert a hand from the third housing 11c side to the second housing 11b side to release the door fixing 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.

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 Figure 9(A) showing a top view of the terminal box 26a, Figure 9(B) showing a front view of the terminal box 26a, and Figure 9(C) showing a side view of the terminal box 26a. The same applies to the terminal box 26b.

Terminal box 26a is composed of a box body 260 and a lid member 262, and its vertical (top-bottom) x horizontal (left-right) x depth (front-back) dimensions 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 body 260 so as to be able to be opened and closed by hinge 264, and is fixed in the closed position by knob 268. When the fixation is released by operating knob 268, lid member 262 is opened as shown in lid member 2620, making it possible to connect a wiring cable to terminal block 280a.

The cover member 262 is made of 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 sides, are arranged on the top and sides of the box body 260, ensuring waterproofing of the wiring cable inserted into the waterproof connectors 266. A terminal block 280a on which a plurality of terminals are arranged is also arranged on the box body 260.

Even if the fire hydrant device 10 is thinned to a predetermined width in the range of about 180 to 200 mm, the depth (front to back) of the terminal boxes 26a, 26b is about 80 mm, so there is sufficient space within the second housing 11b to place the terminal boxes 26a, 26b. In addition, since the terminal boxes 26a, 26b are positioned 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, 26b to the electrical equipment using short wiring.

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 imaginary lines to open the front of the second housing 11b, making it easy to connect the terminal blocks 26a, 26b and the electrical equipment arranged on the first door 18 with signal lines.

Even when the fire hydrant device 10 is installed inside a tunnel, the door lock can be released and the first door 18 and the second door 20 can be opened to the positions shown by the first door 180 and the second door 200 in phantom lines as shown in FIG. 8 to open the front of the second housing 11b, allowing the work of connecting the wiring cable pulled from the first housing 11a to the terminal boxes 26a and 26b to be performed. This makes it possible to easily perform the work without being hindered by the fire extinguisher that was previously stored in the same housing.

(b3. Structure of the third housing)
The structure of the third housing 11c will be described in more detail. Please refer to FIG. 4, which shows the internal structure of the fire hydrant device from the front with the fire hydrant door and the maintenance door open, and FIG. 5, which shows the internal structure of the fire hydrant device in a cross section seen from above. The inside of the third housing 11c is a fire extinguisher storage section 50e, and a space is secured to store two fire extinguishers 72 with an outer diameter of about 150 to 160 mm. As described above, in order to make the fire hydrant device 10 thin, 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, and thus a gap of about 15 to 25 mm is secured in front and behind the stored fire extinguisher 72, making it possible to store the fire extinguisher 72 in the third housing 11c without the fire extinguisher 72 coming into contact with the third housing 11c.

(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 device 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, and the red indicator light 22 is connected to a corresponding terminal of the terminal block 280a of the terminal box 26a, and the transmitter 24, the response lamp 25, and the telephone jack 28 are connected to a corresponding terminal of the terminal block 280b of the terminal box 26b. 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 is different from the actual position, but Fig. 10 shows the cable wiring system of the electrical equipment, and does not show the actual position and arrangement.

In addition, a pump start switch 64 and a pump start interlocking 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.

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 connected to the terminal of the terminal block 280a of the terminal box 26a, thereby being connected to the red indicator light 22.

In addition, a low-voltage cable 55 (which is a single multi-core cable, but is represented as a telephone cable 55a, a response lamp cable 55b, a transmitter cable 55c, and a switch cable 55d in the cable wiring system of FIG. 10) 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 connected to the terminal of the terminal block 280b of the terminal box 26b, thereby connecting it to the telephone jack 28 of the first door 18, the response lamp 25, the transmitter 24, and the pump start switch 64 and pump start interlock switch 65 provided in the valve storage section 50a.

As shown in FIG. 10, the pump start switch 64 and the pump start interlocking switch 65 of the valve storage section 50a are connected to the terminal 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 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 wiring of the transmitter 24 by a jumper wiring to the terminal to which the wiring of the transmitter 24 is connected.

(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.

As a result, the installation space for the terminal boxes 26a, 26b is secured by the second housing 11b, making it possible to thin the width of the fire hydrant device 10 to 2/3 or less 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 making it possible to install the fire hydrant device 10 above the guard passage 35 inside the tunnel with minimal restrictions on the passage width of the guard passage 35.

[c. First embodiment of a fire hydrant device in which the arrangement order of the casings is changed]
The following is a more detailed description of an embodiment of a fire hydrant device in which the order of the three housings divided in the longitudinal direction of the tunnel is changed. 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 order of the first housing 11a, the second housing 11b, and the third housing 11c can be changed as necessary.

The order of the first housing 11a, the second housing 11b, and the third housing 11c can be arbitrary, 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.

In this case, the structures of the first housing 11a, the second housing 11b, and the third housing 11c are basically the same as those shown in Figures 1 to 8, but differ in that the left side surface of the second housing 11b 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.

Also, an electrical door equivalent 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 equivalent to the second door 20 may be provided on the left side of the second housing 11b.

[d. Fire extinguisher box embodiment]

In the embodiment of the fire extinguisher box, the second housing 11b of the first embodiment of the fire hydrant device 10 is replaced by the first housing 110a, and the third housing 11c is replaced by the second housing 110b. As shown in the front view of the fire extinguisher box in Fig. 13(A) and the cross-sectional view of the internal structure of the fire extinguisher box from above in Fig. 13(B), the first housing 110a and the second housing 110b are divided into two parts and arranged from right to left, and are connected to each other. Note that Fig. 13(B) is a cross section of the portion d-d indicated by the dashed line in Fig. 13(A).

The embodiment of the fire extinguisher box 100 has a configuration in which the first housing 11a is deleted from the first embodiment of the fire hydrant device 10, and the first housing 110a is basically similar to the second housing 11b, and the second housing 110b is basically similar to the third housing 11c.

As a result, the width of 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 arranging the terminal boxes 26a and 26b using the first housing 110a, making it possible to install the fire extinguisher box 100 on the monitor passage 35 inside the tunnel while minimizing restrictions on the passage width of the monitor passage 35.

In addition, even 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.

In addition, in the second embodiment of the fire hydrant device 10, like 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 on the monitor's passage 35 inside a tunnel while minimizing restrictions on the passage width of the monitor's passage 35.

In addition, even in this embodiment, the order of the first housing 112a and the second housing 112b can be changed as desired, and the second housing 112b may be connected to the right side of the first housing 112a.

[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 replaced with a first housing 114a, and the second housing 11b and the third housing 11c are replaced with a second housing 114b to form a single housing.

As shown in the cross-sectional top view of the internal structure of the fire hydrant device in FIG. 15(A), the third embodiment of the fire hydrant device 10 is divided into two parts, a first housing 114a and a second housing 114b, from right to left, and is installed by connecting them together. 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 parts, 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 by 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 a-a indicated by the dashed line in FIG. 4, which shows the front of the fire hydrant device 10 in the first embodiment.

In addition, even in this embodiment, the order of the first housing 114a and the second housing 114b can be changed as desired, and the second housing 114b may be connected to the right side of the first housing 114a.

[G. An embodiment of a fire hydrant device in which electrical equipment and a terminal box are arranged in the vertical direction]
The embodiment of the fire hydrant device in which the electrical equipment and the terminal box are arranged in the vertical direction will be described in more detail in the first embodiment of the fire hydrant device having a three-part housing divided structure. Note that the configuration in which the electrical equipment and the terminal box are arranged in the vertical direction can also be applied to the second and third embodiments of the fire hydrant device and the fire extinguisher box having a two-part housing divided structure.

As shown in the front view of the fire hydrant device in FIG. 16, the fire hydrant device 10 is divided and arranged from right to left into a first housing 11a, a second housing 11b, and a third housing 11c, with adjacent housings connected and installed, and the first housing 11a and the third housing 11c are the same as those in the first embodiment of the fire hydrant device.

In contrast, the second housing 11b is the same in that electrical equipment and a terminal box are arranged therein, but differs in the location where they are arranged and in that the first door 18 and the second door 20 arranged at the front opening of the second housing 11b are arranged separately in the vertical direction rather than the horizontal direction.

Now, the second housing 11b of this embodiment will be described in more detail with reference to Figs. 16 to 18. Fig. 17 shows a cross section of the second housing of the fire hydrant device of Fig. 16 as seen from the right side, Fig. 18(A) shows a cross section of the portion where the first door is located as seen from above, and Fig. 18(B) shows a cross section of the portion where the second door is located as seen from above. Note that Fig. 17 is a cross section of the portion e-e indicated by the dashed line in Fig. 16, Fig. 18(A) is a cross section of the portion f-f indicated by the dashed line in Fig. 17, and Fig. 18(B) is a cross section of the portion g-g indicated by the dashed line in Fig. 17.

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 (on the inside of the door) arranged on the left and right sides, and below that, a transmitter 24 and a response lamp 25 arranged on the left and right sides. The first door 18 is supported by hinges 18a at two points above and below on the right end so that it can open sideways to the right as the first door 180 shown by imaginary lines.

The second door 20, located below the front opening of the second housing 11b, is supported at two points, top and bottom, on 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.

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

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.

[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.
