Description

Technical Field

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

Background Art

[0002] Conventionally, in tunnels such as highways and motorways that are areas to be extinguished, a fire hydrant device, which is a type of disaster prevention equipment storage device shown in FIG. 19, for example, is generally installed by cutting out the wall surface of the tunnel body at intervals of, for example, 50 meters in the longitudinal direction of the tunnel. Note that FIG. 19(A) shows the front of the fire hydrant device, and FIG. 19(B) shows a cross section viewed from above the fire hydrant device. Note that FIG. 19(B) is a cross section at the position h-h indicated by the broken line in FIG. 19(A).

[0003] Here, in the description of FIG. 19, the X - Y - Z directions are orthogonal to each other. Specifically, when looking at the front of the fire hydrant device as shown in FIGS. 19(A) and (B), the X direction is the left - right direction, the Y direction is the up - down direction, and the Z direction is the front - 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 upper side, the -Y side is the lower side, the +Z side in the Z direction is the front side, and the -Z side is the rear side. This is the same in FIGS. 1 to 18, which are embodiments of the present invention.

[0004] As shown in FIG. 19, a conventional fire hydrant device 10 includes a fire hydrant storage section 15a in a housing 111a having an openable and closable fire hydrant door 12 and a maintenance door 14, in which a fire - fighting hose 60 and valves (not shown) are stored as fire hydrant equipment. Also, in a fire extinguisher storage section 15b in a housing 111b having an openable and closable fire extinguisher door 16 and an electrical equipment door 180, for example, two fire extinguishers 72 are stored. On the electrical equipment door 180, as electrical equipment, for example, a red indicator lamp 22 whose supplied power is AC100V, a transmitter 24 whose supplied power is DC48V, a response lamp 25, a telephone jack 28 (inside the housing of the electrical equipment door), etc. are provided. Also, in cold regions, a space heater whose supplied power is AC200V is further installed.

[0005] And the power supplies for these electrical equipment are supplied by high-voltage wiring cables (power cables) and low-voltage wiring cables (control cables) drawn from outside the fire hydrant device 10 to the side of the fire hydrant storage part 15a in the housing 111a passing through any space in the fire hydrant storage part 15a and being connected via a high-voltage terminal box 26a or a low-voltage terminal box 26b arranged in the fire extinguisher storage part 15b in the housing 111b.

[0006] By the way, when it is difficult to provide an embedding part (recess) of the fire hydrant device by punching out a box or the like on the wall surface of the tunnel structure body, the fire hydrant device needs to be installed in a state of being exposed on the road surface of the inspector passage.

[0007] In such a case, a gantry structure for wall-mounting the fire hydrant device on the wall surface of the tunnel structure body has been proposed, and the gantry is composed of a main support part fixed to the wall surface of the tunnel structure body and a posture holding member for holding the posture of the fire hydrant device (Patent Document 2).

Summary of the Invention

Problems to be Solved by the Invention

[0009] However, in the case of the fire hydrant device having a wall-mounted structure on the wall surface of the tunnel structure body, since the fire hydrant device is installed at a predetermined height from the road surface of the inspector passage, the attachment of the fire hydrant device to the wall surface of the tunnel structure body is quite difficult, and many problems such as man-hours and time consumption remain.

[0010] Therefore, in order to solve the problems of the fire hydrant device with the wall-mounted structure, it is conceivable to adopt a so-called floor-standing structure in which the fire hydrant device is installed in an exposed state on the road surface of the supervisor passage that is easy to install. However, the installation of the fire hydrant device will restrict the width (front-rear direction) of the supervisor passage. In order to ensure the passage width of the supervisor passage, thinning the width (front-rear direction) of the fire hydrant device as much as possible remains an issue to be solved. The same applies to the wall-mounted structure.

[0011] By the way, when thinning the fire hydrant device 10, the width of the fire hydrant device 10 is determined by the size of the fire extinguisher 72 housed in the fire hydrant device 10. Since the outer diameter of the fire extinguisher 72 is about 150 - 160 mm, for example, considering that the housed fire extinguisher 72 does not contact the housing 111b, the width of the fire hydrant device 10 can be thinned to about 180 mm - 200 mm.

[0012] Here, the size of the conventional fire hydrant device 10 is defined to unify the size of the cut-out for the box on the wall surface of the tunnel structure. For example, it is about 1040 mm (vertical direction) × 1780 mm (horizontal direction) × 300 mm (front-rear direction). Since a width of about 300 mm of the fire hydrant device 10 is ensured, the fire extinguisher 72 is housed in the fire extinguisher storage part 15b, and the terminal boxes 26a, 26b are arranged on the rear surface inside the housing 111b behind the fire extinguisher 72, and sufficient space is ensured for wiring the power cables and weak current cables connected to the terminal boxes 26a, 26b.

[0013] However, when thinning the fire hydrant device 10, since the width of the fire hydrant device 10 changes from 300 mm to about 180 mm - 200 mm, the arrangement of the fire extinguisher 72, the terminal boxes 26a, 26b, and the wiring cables in the fire extinguisher storage part 15b cannot be the same as that of the conventional fire hydrant device 10, which has become an obstacle to the thinning of the fire hydrant device 10.

[0014] An object of the present invention is to provide a fire hydrant device and a fire extinguisher box that enable thinning without being restricted by the fire hydrant equipment, electrical equipment, terminal boxes, fire extinguishers, etc. arranged in 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 fire hydrant equipment, a terminal box, and a fire extinguisher are arranged in a housing, The housing is, a first housing in which fire hydrant equipment is arranged, a second housing in which electrical equipment and a terminal box are arranged, a third housing in which a fire extinguisher is arranged, and is composed of, The first housing, the second housing, and the third housing are arranged in a predetermined order along a predetermined one direction and are installed in a state where adjacent housings are connected.

[0016] (Fire Hydrant Device of the Second Invention) The present invention is a fire hydrant device in which fire hydrant equipment, a terminal box, and a fire extinguisher are arranged in a housing, The housing is, a first housing in which fire hydrant equipment, electrical equipment, and a terminal box are arranged, a second housing in which a fire extinguisher is arranged, and is composed of, The first housing and the second housing are arranged in a predetermined order along a predetermined one direction and are installed in a connected state, The interior of the first housing is divided into a fire hydrant storage section where fire hydrant equipment is arranged and an electrical equipment / terminal box storage section where electrical equipment and a terminal box are arranged, The fire hydrant storage section and the electrical equipment / terminal box storage section are arranged in a predetermined order along a predetermined one direction within the first housing.

[0017] (Fire Hydrant Device of the Third Invention) The present invention is a fire hydrant device in which fire hydrant equipment, a terminal box, and a fire extinguisher are arranged in a housing, The housing is, a first housing in which fire hydrant equipment is arranged, a second housing in which electrical equipment, a terminal box, and a fire extinguisher are arranged, and is composed of, The first housing and the second housing are arranged in a predetermined order along a predetermined one direction, and are installed in a connected state. The interior of the second housing is divided into an electrical equipment and terminal box storage section where electrical equipment and terminal boxes are arranged, and a fire extinguisher storage section where fire extinguishers are arranged. The electrical equipment and terminal box storage section and the fire extinguisher storage section are characterized in that they are arranged in a predetermined order along a predetermined one direction within the second housing.

[0018] (Thinned fire hydrant device) The width of the housing is set to a predetermined width corresponding to the outer diameter of the fire extinguisher.

[0019] (Fire hydrant device arranged on the road surface of the monitor passage in the tunnel) The housing is installed at a predetermined height on the road surface of the monitor passage provided along the inner wall surface of the tunnel having a road, so as to be close to the wall surface of the tunnel. The predetermined one direction is the direction along the wall surface of the tunnel.

[0020] (Door for terminal box and electrical equipment) A first door corresponding to the arrangement position of the electrical equipment and a second door corresponding to the arrangement position of the terminal box are provided on the housing.

[0021] (Arrangement of terminal box and electrical equipment) The electrical equipment and terminal boxes are arranged along a predetermined one direction or the height direction in the installation state.

[0022] (Fire extinguisher box of the fourth invention) The present invention is a fire extinguisher box in which electrical equipment, terminal boxes, and fire extinguishers are arranged in a housing, The housing is a first housing in which electrical equipment and terminal boxes are arranged, a second housing in which fire extinguishers are arranged, and is composed of The first housing and the second housing are arranged in a predetermined order along a predetermined one direction and are installed in a connected state.

[0023] Other features of the fire extinguisher box of the present invention are basically the same as those of the fire hydrant device described above, and thus the description thereof is omitted.

Advantages of the Invention

[0024] (Advantages 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 fire hydrant equipment is arranged, a second housing in which electrical equipment and a terminal box are arranged, and a third housing in which a fire extinguisher is arranged. They are arranged in a predetermined order along a predetermined one-way direction and installed in a state where adjacent housings are connected. Therefore, without being restricted by the arrangement space of the terminal box, which was a factor making it difficult to thin down the conventional fire hydrant device, and the wiring space of the wiring cable connected to the terminal box, it is possible to thin down the fire hydrant device.

[0025] Also, by arranging the terminal box in the same housing as the electrical equipment which is the connection destination of the wiring cable, it is possible to shorten the wiring length of the wiring cable compared to the conventional fire hydrant device in which the terminal box was arranged behind the fire extinguisher, and facilitate the routing of the wiring.

[0026] Moreover, since the housing is divided according to the components to be arranged, the configuration of the fire hydrant device can be flexibly changed according to requirements and specification changes. Also, for example, by configuring only the second housing and the third housing, the fire hydrant device can be changed to a fire extinguisher box, etc., and equipment sharing can be achieved, leading to cost reduction. Also, for equipment changes due to rank up / down of tunnel grade, etc., it is possible to flexibly respond at the work site.

[0027] The advantages of the fire hydrant device of the first invention described above are the same for the fire hydrant devices of the second and third inventions.

[0028] (Advantages of the thinned fire hydrant device) In addition, since the fire hydrant device can be made thinner without being restricted by the installation space of the terminal box and the wiring space of the wiring cable connected to the terminal box, the fire hydrant device can be made thinner to a predetermined width corresponding to the outer diameter of the fire extinguisher, for example, about 180 mm to 200 mm, and can be made thinner to less than 2 / 3 of the conventional fire hydrant device that is embedded in the tunnel wall after punching out the box.

[0029] (Effect of the fire hydrant device arranged on the road surface of the monitor passage in the tunnel) In addition, the housing is provided at a predetermined height on the road surface of the monitor passage provided along the inner wall surface of the tunnel, so as to be close to the wall surface of the tunnel, and each divided housing is installed in the direction along the wall surface of the tunnel. Therefore, combined with the fact that the fire hydrant device is made thinner, it is possible to install the fire hydrant device while minimizing the restriction on the passage width of the monitor passage.

[0030] (Effect of the door on the terminal box and electrical equipment) In addition, since the first door corresponding to the arrangement position of the electrical equipment and the second door corresponding to the arrangement position of the terminal box are provided separately, it is only necessary to open the second door for wiring work or maintenance work on the terminal box. Compared with the conventional fire hydrant device arranged at the rear of the fire extinguisher and without a door for the terminal box, it is possible to improve the workability and maintainability for the terminal box. Also, if the first door is opened together, the opening area will be wider accordingly, and it is further possible to improve the workability and maintainability for the terminal box.

[0031] (Effect of the arrangement of the terminal box and electrical equipment) In addition, since the electrical equipment and the terminal box are arranged along a predetermined one direction or the height direction in the installation state, the electrical equipment and the terminal box will be arranged in the housing along the direction that does not affect the width of the fire hydrant device. In the thinning of the fire hydrant device, the arrangement space of the terminal box and the wiring space of the wiring cable connected to the terminal box will not be restricted.

[0032] The effect of the fire extinguisher box according to the present invention is the same as that of the fire hydrant device described above, and thus the description thereof is omitted.

Embodiments for Carrying Out the Invention

[0034] Hereinafter, embodiments of the fire hydrant device and the 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 by the following embodiments.

[0035] [Basic Concepts of the Embodiment] First, the basic concepts of the embodiment will be described. The embodiment generally relates to a fire hydrant device in which fire hydrant equipment, electrical equipment, a terminal box, and a fire extinguisher are arranged in a housing, and a fire extinguisher box in which electrical equipment, a terminal box, and a fire extinguisher are arranged in a housing.

[0036] Here, the "fire hydrant device" is a type of emergency equipment installed in tunnels on highways or motorways that are the areas to be extinguished. It is a device in which 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 are arranged in a housing installed in the area to be extinguished, and it is a concept including the fire hydrant equipment in which the fire hydrant device is installed.

[0037] Also, the "fire extinguisher box" is a type of emergency equipment installed in tunnels on highways or motorways that are the areas to be extinguished. It is a device in which electrical equipment such as a red indicator light and a transmitter on an electrical door, a terminal box, and a fire extinguisher are arranged in a housing installed in the area to be extinguished.

[0038] In addition, the "arrangement" of the fire hydrant equipment, electrical equipment, terminal box, and fire extinguisher with respect to the fire hydrant device or fire extinguisher box is a concept that includes "storage".

[0039] 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).

[0040] The housing of the fire hydrant device of the First Invention is composed of a first housing where the fire hydrant equipment is arranged, a second housing where the electrical equipment and the terminal box are arranged, and a third housing where the fire extinguisher is arranged. The first housing, the second housing, and the third housing are arranged in a predetermined order along a predetermined one direction, and are installed in a state where adjacent housings are connected.

[0041] Here, the "fire hydrant equipment" is a predetermined equipment including valves such as a fire hose and a fire hydrant valve. The "electrical equipment" is a predetermined equipment including a red indicator light, a transmitter, a response lamp, and a telephone jack. The "terminal box" is a storage box equipped with a terminal block for connecting a wiring cable or the like drawn into the housing from the outside of the fire hydrant device to the electrical equipment.

[0042] In addition, the "predetermined one direction" is a direction substantially orthogonal to the direction of 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 one direction. The "predetermined order" means that the arrangement order of each housing is arbitrary.

[0043] The housing of the fire hydrant device of the Second Invention is composed of a first housing where the fire hydrant equipment, electrical equipment, and terminal box are arranged, and a second housing where the fire extinguisher is arranged. The first housing and the second housing are arranged in a predetermined order along a predetermined one direction and are installed in a connected state. The inside of the first housing is divided into a fire hydrant storage part where the fire hydrant equipment is arranged and an electrical equipment / terminal box storage part where the electrical equipment and the terminal box are arranged. The fire hydrant storage part and the electrical equipment / terminal box storage part are arranged in a predetermined order along a predetermined one direction inside the first housing.

[0044] Further, the housing of the fire hydrant device of the third invention is composed of a first housing in which fire hydrant equipment is arranged and a second housing in which electrical equipment, terminal boxes, and fire extinguishers are arranged. The first housing and the second housing are arranged in a predetermined order along a predetermined one direction and installed in a connected state. The interior of the second housing is divided into an electrical equipment and terminal box storage part where electrical equipment and terminal boxes are arranged and a fire extinguisher storage part where fire extinguishers are arranged. The electrical equipment and terminal box storage part and the fire extinguisher storage part are arranged in a predetermined order along a predetermined one direction inside the second housing.

[0045] Here, the "electrical equipment and terminal box storage part" refers to the space including the area where electrical equipment and terminal boxes inside the housing are arranged, and the "fire extinguisher storage part" refers to the space including the area where fire extinguishers inside the housing are arranged. Also, "dividing the storage part" includes both physically dividing the space like a partition board and conceptually dividing the space without being physically partitioned.

[0046] Further, the width of the housing may be a predetermined width corresponding to the outer diameter of the fire extinguisher. The "predetermined width corresponding to the outer diameter of the fire extinguisher" means that since the outer diameter of the fire extinguisher is about 150 - 160 mm, for example, it is a width considered so that the fire extinguisher does not contact the housing. Specifically, it is a width of about 180 mm - 200 mm and refers to the length in a direction not in the height direction that is substantially orthogonal to the predetermined one direction.

[0047] Further, the housing may be installed at a predetermined height on the road surface of the inspector passage provided along the inner wall surface of the tunnel having a road, close to the wall surface of the tunnel. In this case, the predetermined one direction is the direction along the wall surface of the tunnel. Also, the "predetermined height" is a height at which the fire hydrant device can be installed close to the tunnel wall surface. For example, by installing a pedestal on the road surface of the inspector passage and installing the housing on the pedestal, the installation height of the fire hydrant device is adjusted to the predetermined height.

[0048] Further, the housing may be provided with a first door corresponding to the arrangement position of the electrical equipment and a second door corresponding to the arrangement position of the terminal box. Here, the "first door" and the "second door" are merely names for distinguishing whether the door is provided corresponding to the arrangement position of the electrical equipment or the door provided corresponding to the arrangement position of the terminal box, and do not indicate that there are differences in the configuration of the doors. That is, it does not prevent the "first door" and the "second door" from being doors with the same configuration or doors with different configurations.

[0049] Further, the electrical equipment and the terminal box in the housing may be arranged along a predetermined one direction or the height direction in the installation state.

[0050] Further, the housing of the fire extinguisher box according to the fourth invention is composed of a first housing in which the electrical equipment and the 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 one direction and installed in a connected state.

[0051] Hereinafter, specific embodiments will be described. In the specific embodiments shown below, the case where "the fire hydrant device is installed on a pedestal installed on the monitor passage in the tunnel", the "terminal box" is the "terminal box for high voltage and low voltage", and the "predetermined one direction" is the "longitudinal direction of the tunnel" will be described.

Embodiment of the fire hydrant device with the electrical equipment and the terminal box arranged in the vertical direction h. Modification example of the present invention

[0053] [a. First embodiment of the fire hydrant device] The first embodiment of the fire hydrant device with the housing divided into three parts in the longitudinal direction of the tunnel will be described in more detail. FIG. 1 is an explanatory view showing the installation state of the fire hydrant device according to the first embodiment in the tunnel. FIG. 1(A) shows the installation state of the fire hydrant device as seen in the cross section of the tunnel, and FIG. 1(B) shows the installation state of the fire hydrant device as seen in the direction of the tunnel wall surface.

[0054] (a1. Outline of the fire hydrant device of the first embodiment) The outline 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 arranged by dividing the first housing 11a, the second housing 11b, and the third housing 11c from right to left, and the adjacent housings are connected and installed.

[0055] Specifically, as shown in the cross-sectional view of the housing division structure of FIG. 2 seen from above, the housing of the fire hydrant device 10 is divided into three parts: the first housing 11a, the second housing 11b, and the third housing 11c. The right side surface of the second housing 11b is connected and fixed to the left side surface of the first housing 11a by bolts 76 and nuts 78, and the right side surface of the third housing 11c is connected and fixed to the left side surface of the second housing 11b by bolts 76 and nuts 78.

[0056] Also, as shown in FIG. 1(B), a decorative frame 13a is attached to the front surface of the first housing 11a. The door opening of the decorative frame 13a is divided vertically. An inclined front-opening fire hydrant door 12 that opens downward by a hinge 12a is arranged below the door opening, and a maintenance door 14 that opens upward by a hinge 14a is arranged above the door opening. Predetermined fire hydrant equipment including a fire hose and valves such as a fire hydrant valve is stored in the fire hydrant storage section inside the first housing 11a.

[0057] Further, a decorative frame 13b is attached to the front surface of the second housing 11b. The door opening of the decorative frame 13b is divided horizontally. A first door 18 that opens horizontally to the right by a hinge 18a is arranged on the right side, and a second door 20 that opens horizontally to the left by a hinge 20a is arranged on the left side. The first door 18 functions as an electrical equipment door, and as electrical equipment, for example, a red indicator lamp 22, a transmitter 24, and a response lamp 25 are provided. A telephone jack is provided inside the first door 18.

[0058] The red indicator lamp 22 is always lit so that the installation location of the fire hydrant device 10 can be confirmed from a distance. When a fire occurs and the transmitter 24 is pressed to turn on the push-button switch, a transmission signal is sent, and a fire alarm is output from the fire prevention receiving panel in the electrical room that receives this signal. The fire hydrant device 10 receives a response signal from the fire prevention receiving panel, causing the red indicator lamp 22 to blink and the response lamp 25 to light up.

[0059] On the rear surface inside the second housing 11b opposite to the second door 20, a high-voltage terminal box 26a and a low-voltage terminal box 26b are arranged in the vertical direction. The high-voltage terminal box 26a uses the built-in terminal block to connect the power cable for strong electricity drawn from outside the fire hydrant device 10 and the red indicator lamp 22. The low-voltage terminal box 26b uses the built-in terminal block to connect the power cable for weak electricity drawn from outside the fire hydrant device 10 and the transmitter 24, the response lamp 25, the telephone jack, etc.

[0060] Further, a decorative frame 13c is attached to the front surface of the third housing 11c. A fire extinguisher door 16 that opens horizontally to the left by a hinge 16a is provided at the door opening of the decorative frame 13c, and, for example, two fire extinguishers can be stored in a fire extinguisher storage section that is inside the third housing 11c. Further, a viewing window 17 is provided below the fire extinguisher door 16, enabling confirmation of the presence or absence of a fire extinguisher from the outside.

[0061] (a2. Installation of the fire hydrant device) The installation of the fire hydrant device in the tunnel will be described in more detail. A road 36 is constructed in the longitudinal direction (left - right direction) of the tunnel at the lower part of a cylindrical (circular cross - section) tunnel body constructed by the shield method, and a supervisor passage 35 at a predetermined height with respect to the road 36 is constructed below the lower side of the tunnel wall surface 26 along the rear side of the road 36.

[0062] Since it is difficult to cut out a box for installing the fire hydrant device 10 in the tunnel wall surface 26 constructed by the shield method, a gantry 30 is installed on the road surface of the supervisor passage 35 close to the tunnel wall surface 26, and the first housing 11a, the second housing 11b, and the third housing 11c to which the fire hydrant device 10 is connected are attached and fixed on the gantry 30 for installation. Here, the height H1 of the gantry 30 is set so that the height from the road surface of the supervisor passage 35 to the transmitter 24 arranged in the fire hydrant device 10 falls between 800 mm and 1500 mm defined by law.

[0063] Further, the gantry 30 of the present embodiment is composed of a first gantry 32 and a second gantry 34. As shown in FIG. 1(A), the first gantry 32 has an inverted trapezoidal side shape with the upper side longer than the bottom side, and the rear side is an inclined surface that slopes downward obliquely along the curved shape of the tunnel wall surface 26. The second gantry 34 is fixed on the first gantry 32, and the first housing 11a, the second housing 11b, and the third housing 11c to which the fire hydrant device 10 is connected are attached and fixed.

[0064] (a3. Installation height and thinning of the fire hydrant device) 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 due to the protrusion (bulge) of the fire hydrant device 10 installed on the road surface of the supervisor passage 35 by the pedestal 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 thinned as much as possible.

[0065] First, since the installation height of the fire hydrant device 10 is determined by the pedestal 30, the optimization of the height H1 of the pedestal 30 will be described in more detail. Fig. 3 schematically shows the installation state of the fire hydrant device in the tunnel cross section. The tunnel wall surface 26 where the fire hydrant device 10 is installed has a circular cross section. In Fig. 3(A), with respect to the horizontal tunnel center line SL1 from the tunnel center (center of the circular cross section) P, for the fire hydrant device 10 installed on the supervisor passage 35, the height H1 of the pedestal 30 is set so that the lateral housing center line SL2 passing through the center in the height direction approaches as close as possible.

[0066] In this case, the closer the housing center line SL2 is to the tunnel center line SL1, the more the degree of protrusion of the fire hydrant device 10 from the tunnel wall surface 26 can be reduced.

[0067] Fig. 3(B) shows the case where the height H1 of the pedestal 30 is set so that the housing center line SL2 coincides with the tunnel center line SL1. In this case, the degree of protrusion of the fire hydrant device 10 from the tunnel wall surface 26 can be minimized. However, the height H1 of the pedestal 30 is adjusted within a possible range in consideration of taking out the fire extinguisher, etc.

[0068] Next, the thinning of the fire hydrant device 10 will be described in more detail. Among 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-rear direction. If the width (front-rear direction) of the fire hydrant device is up to the size where the fire extinguisher can be housed in the third housing 11c, the fire hydrant device 10 can be thinned. Therefore, the width of the fire hydrant device 10 is set to a predetermined width corresponding to the outer diameter of the fire extinguisher housed in the third housing 11c.

[0069] The outer diameter of the fire extinguisher is about 150 to 160 mm. When a gap is secured so that the stored fire extinguisher does not contact the third housing 11c, the minimum width of the fire hydrant device 10 is, for example, in the range of about 180 to 200 mm, and the width of the fire hydrant device 10 is set to a predetermined width within this range. On the other hand, since the width of the conventional fire hydrant device 10 in which the wall surface of the tunnel body is cut out and embedded is about 300 mm, the width of the fire hydrant device 10 of the present embodiment can be made 2 / 3 or less of the conventional one, and the fire hydrant device 10 can be made thinner.

[0070] (a4. Configuration corresponding to thinning of the 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 and 26b on the rear surface of the housing behind the fire extinguisher storage portion where the fire extinguisher is stored, as in the conventional fire hydrant device 10 shown in FIG. 19. Therefore, in the present embodiment, a configuration is adopted in which the first housing 11a, the second housing 11b, and the third housing 11c, which are divided into three in the longitudinal direction (left - right direction) of the tunnel, are connected. The housing (second housing 11b) for arranging the electrical equipment and the housing (third housing 11c) for arranging the fire extinguisher are separated, and the terminal boxes 26a and 26b are not arranged in the third housing 11c for arranging the fire extinguisher, but are arranged in the second housing 11b in which the electrical equipment is arranged.

[0071] [b. Structure of the fire hydrant device] The internal structure of the fire hydrant device, which is divided into three and connected to the first housing 11a, the second housing 11b, and the third housing 11c, will be described in more detail with reference to FIGS. 4 to 9.

[0072] (b1. Structure of the first housing) The structure of the first housing 11a will be described in more detail. Refer to FIG. 4 showing the internal structure of the fire hydrant device from the front with the fire hydrant door and the maintenance door open, FIG. 5 showing a cross - section of the internal structure of the fire hydrant device viewed from above, and FIG. 6 showing a cross - section of the hose storage portion of the first housing viewed from the right side. FIG. 5 is a cross - section at the location a - a indicated by the broken line in FIG. 4, and FIG. 6 is a cross - section at the location b - b indicated by the broken line in FIG. 4.

[0073] Inside the first housing 11a that serves as a fire hydrant storage section, it is divided into a valve storage section 50a and a hose storage section 50b. In the valve storage section 50a, the water supply pipe 48 is drawn in from below through the pedestal 30 and connected to the water supply faucet 52. Also, the water supply pipe 48 branches downward, and a fire hydrant valve 54 and a pressure regulating valve 56 are provided at the branch end, and then a fire hose 60 is connected. The fire hydrant valve 54 is opened and closed by the fire hydrant valve opening and closing lever 58. When the fire hydrant valve opening and closing lever 58 is operated to open and close, the fire hydrant valve 54 is remotely opened and closed by a known wire link mechanism. Also, when the fire hydrant valve opening and closing lever 58 is operated to open and close, the pump start interlocking switch provided in the operation box is turned on and off. Also, on the upper right of the water supply faucet 52, a pump start switch 64 used by the fire department is provided.

[0074] In the hose storage section 50b, a hose storage frame 62 is provided, and the fire hose 60 drawn in from below is stored in an inward winding state in a clockwise or counterclockwise direction. Also, a nozzle 68 is attached to the tip of the fire hose 60 drawn out through the hose guide 66 and is detachably held by the nozzle holder 70. Also, in the upper part of the hose storage section 50b, a cable rack 49 is provided to route the wiring cable drawn in from the outside of the first housing 11a to the second housing 11b side, and a wire passing port is opened in the partition wall of the first housing 11a opposite to the left end of the cable rack 49.

[0075] (b2. Structure of the second housing) The structure of the second housing 11b will be described in more detail. Refer to FIG. 4 showing the internal structure of the fire hydrant device in the front view with the fire hydrant door and the maintenance door opened, FIG. 5 showing a cross-section of the internal structure of the fire hydrant device viewed from above, FIG. 7 showing a cross-section of the electrical equipment storage section of the second housing viewed from the right side, and FIG. 8 showing a cross-section of the second housing viewed from above. FIG. 7 is a cross-section at the location c-c indicated by the broken line in FIG. 4, and FIG. 8 is a detailed view of the part of the second housing in FIG. 5 taken out.

[0076] The interior of the second housing 11b is divided into an electrical equipment storage section 50c and a terminal box storage section 50d. At the opening on the front surface of the second housing 11b corresponding to the electrical equipment storage section 50c, a first door 18 that opens horizontally to the right by means of a hinge 18a is arranged. On the first door 18, as shown in FIG. 7, a red indicator lamp 22, a transmitter 24, a telephone jack 28, and a response lamp 25 are arranged in order from the top. The telephone jack 28 is arranged inside the first door 18.

[0077] Here, among the electrical equipment, the one with the largest size in the front-rear direction inside the second housing 11b is the red indicator lamp 22, and its size is about 120 mm. Therefore, even when the fire hydrant device 10 is thinned down to a predetermined width in the range of about 180 to 200 mm, each electrical equipment can be arranged after securing a wiring cable routing space drawn in from the first housing 11a side.

[0078] Also, at the opening on the front surface of the second housing 11b corresponding to the terminal box storage section 50d, a second door 20 that opens horizontally to the left by means of a hinge 20a is arranged. As shown in FIG. 7, terminal boxes 26a, 26b are arranged vertically on the rear surface of the housing inside the second housing 11b opposite to the second door 20.

[0079] As shown in FIG. 8 for example, the first door 18 has its left end bent inside the housing 11b and is arranged to abut on a surface (door mating surface) that faces the surface on the housing side of the right end of the second door 20 in the closed position. Also, 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 optional. For example, second fixing screws may be provided so as to be operable from the outside of the housing 11b, or magnet members may be provided on the door mating surface for fixing by magnetic adsorption to the second door 20.

[0080] Also, in the partition wall connecting to the first housing 11a on the right side of the second housing 11b, a wire passing hole 80 is formed for drawing in the wiring cable inserted into the cable rack 49 of the first housing 11a. Further, in the partition wall connecting to the third housing 11c on the left side of the second housing 11b, the fire extinguisher door 16 of the third housing 11c is opened and from the third housing 11c side second putting a hand into the housing 11b side to release the door fixation of the first door 18 and the second door 20 second An opening 82 is formed for use in releasing from the inside of the housing 11b, etc., but the opening 82 may not be formed.

[0081] Here, the terminal boxes 26a, 26b arranged in the second housing 11b will be described in more detail. FIG. 9 shows the terminal box 26a arranged in the second housing 11b taken out. FIG. 9(A) shows a top view of the terminal box 26a, FIG. 9(B) shows a front view of the terminal box 26a, and FIG. 9(C) shows a side view of the terminal box 26a. Note that the terminal box 26b is the same.

[0082] The terminal box 26a is composed of a box body 260 and a lid member 262. second The size in the vertical (up and down) × horizontal (left and right) × depth (front and back) dimensions when arranged in the housing 11b is about 220 mm × 140 mm × 80 mm. The lid member 262 is arranged to be openable and closable by a hinge 264 at the opening of the box body 260 and is fixed to the closed position by a knob 268. When the fixation is released by operating the knob 268, the lid member 262 is opened as shown in the lid member 2620, enabling the connection work of the wiring cable to the terminal block 280a.

[0083] Also, the lid member 262 is made of a transparent resin so that the internal terminal block 280a can be seen. A plurality of waterproof connectors 266, for example, two each on the top surface and the side surface, are arranged on the top surface and the side surface of the box body 260 to ensure the waterproofness of the wiring cable inserted into the waterproof connector 266. Further, a terminal block 280a with a plurality of terminals arranged is arranged in the box body 260.

[0084] Even when the fire hydrant device 10 is thinned to a predetermined width in the range of about 180 to 200 mm, since the depth (front-rear) size of the terminal boxes 26a and 26b is about 80 mm, sufficient space is secured in the second housing 11b to arrange the terminal boxes 26a and 26b. Further, since the terminal boxes 26a and 26b are arranged at positions close to the electrical equipment such as the red indicator lamp 22 arranged on the first door 18, connection between the terminal boxes 26a and 26b and the electrical equipment can be achieved with a short wiring length.

[0085] For this reason, at the stage of assembling the second housing 11b in the factory or the like, as shown in FIG. 8, by opening the first door 18 and the second door 20 at the positions of the first door 180 and the second door 200 indicated by imaginary lines, the front surface of the second housing 11b is opened, and it becomes possible to easily perform the work of connecting the terminal blocks 26a and 26b and the electrical equipment arranged on the first door 18 with signal lines.

[0086] Also, even when the fire hydrant device 10 is installed in a tunnel, by releasing the door fixation and opening the first door 18 and the second door 20 at the positions indicated by the first door 180 and the second door 200 indicated by imaginary lines as shown in FIG. 8, the front surface of the second housing 11b is opened, and the work of connecting the wiring cable drawn from the first housing 11a to the terminal boxes 26a and 26b can be performed. It is possible to easily perform the work without being hindered by the wiring work for the fire extinguisher that was conventionally housed in the same housing.

[0087] (b3. Structure of the third housing) The structure of the third housing 11c will be described in more detail. Refer to FIG. 4 showing the internal structure of the fire hydrant device from the front with the fire hydrant door and the maintenance door open, and FIG. 5 showing a cross-section of the internal structure of the fire hydrant device viewed from above. The interior of the third housing 11c is a fire extinguisher storage section 50e, which secures a space capable of storing two fire extinguishers 72 with an outer diameter of about 150 to 160 mm. Also, as described 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. As a result, a gap of about 15 to 25 mm is secured in front of and behind the stored fire extinguisher 72, enabling the fire extinguisher 72 to be stored in the third housing 11c without contacting the third housing 11c.

[0088] (b4. Cable Wiring System of Fire Hydrant Device) 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, on the first door 18 of the second housing 11b, as electrical equipment, a red indicator lamp 22, a transmitter 24, a response lamp 25, and a telephone jack 28 are provided. The red indicator lamp 22 is connected to the 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 the corresponding terminals of the 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 is different from the actual position, but FIG. 10 shows the cable wiring system of the electrical equipment and not the actual position and arrangement.

[0089] Also, in the valve storage section 50a of the first housing 11a of the fire hydrant device 10, a pump start switch 64 and a pump start interlock switch 65 are provided, and they 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.

[0090] In the valve storage section 50a of the first housing 11a, a high-voltage cable 53 for supplying an external AC 100V power source is drawn in, led out to the second housing 11b side through the cable rack 49, and connected to the terminals of the terminal block 280a of the terminal box 26a, thereby being connected to the red indicator lamp 22.

[0091] Also, in the valve storage section 50a of the first housing 11a, a low-voltage cable 55 (a multi-core cable for supplying an external DC 48V power source. Although it is a single multi-core cable, in the cable wiring system of FIG. 10, it is represented as a telephone cable 55a, a response lamp cable 55b, a transmitter cable 55c, and a switch cable 55d.) is drawn in, led out to the second housing 11b side through the cable rack 49, and connected to the terminals of the terminal block 280b of the terminal box 26b, thereby being connected to the telephone jack 28, the response lamp 25, the transmitter 24 of the first door 18, and the pump start switch 64 and the pump start interlock switch 65 provided in the valve storage section 50a.

[0092] As shown in FIG. 10, the pump start switch 64 and the pump start interlock switch 65 in the valve storage section 50a are configured to be 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 interlock switch 65 is connected to the terminal portion of the pump start switch 64. Also, the terminals of the terminal block 280b of the terminal box 26b to which the wiring of the pump start switch 64 and the pump start interlock switch 65 are connected are configured such that the wiring of the pump start switch 64 and the pump start interlock switch 65 is connected to the wiring of the transmitter 24 through a cross-wiring with the terminals to which the wiring of the transmitter 24 is connected.

[0093] (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. The housing of the fire hydrant device 10 is divided into a first housing 11a in which fire-fighting hoses 60, valves and other fire hydrant equipment are arranged, a second housing 11b in which electrical equipment such as a red indicator light 22 and a transmitter 24 and terminal boxes 26a and 26b are arranged, and a third housing 11c in which the fire extinguisher 72 is arranged, and the adjacent housings are connected and installed.

[0094] Therefore, since the installation space for the terminal boxes 26a and 26b can be secured by the second housing 11b, it is possible to reduce the thickness of the fire hydrant device 10 to 2 / 3 or less of the width of the conventional fire hydrant device 10 that is embedded in the wall surface of the tunnel body by cutting out the box, and it is possible to install the fire hydrant device 10 on the monitor passage 35 in the tunnel while minimizing the restriction on the passage width of the monitor passage 35.

[0095] [c. First Embodiment of Fire Hydrant Device with Rearranged Housing Order] An embodiment of a fire hydrant device with the order of the three divided housings in the tunnel longitudinal direction 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 installed with adjacent housings connected. However, the order of the first housing 11a, the second housing 11b, and the third housing 11c can be changed as needed.

[0096] The order of the first housing 11a, the second housing 11b, and the third housing 11c is arbitrary. However, FIG. 12 shows an example of the fire hydrant device 10 with the housing order changed. The fire hydrant device 10 in FIG. 12 has the order of the second housing 11b and the third housing 11c swapped, and is configured such that the third housing 11c is connected to the left side of the first housing 11a and the second housing 11b is connected to the left side of the third housing 11c.

[0097] 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 FIGS. 1 to 8. However, the left side surface of the second housing 11b arranged 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 in order to pass the wiring cable, which is different.

[0098] Further, an electrical equipment door corresponding to the first door 18 may be provided as a single door on the front surface of the second housing 11b arranged at the left end, and a door corresponding to the second door 20 may be provided on the left side surface of the second housing 11b.

[0099] [d. Embodiment of Fire Extinguisher Box] The first embodiment of the fire extinguisher box will be described in more detail. The embodiment of the fire extinguisher box is obtained by using the second housing 11b of the first embodiment of the fire hydrant device 10 as the first housing 110a and the third housing 11c as 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 in FIG. 13(B) seen from above, the first housing 110a and the second housing 110b are arranged in two parts from right to left and are connected and arranged. Note that FIG. 13(B) is a cross-section at the position d-d indicated by the broken line in FIG. 13(A).

[0100] Fire Extinguisher Box 100 The embodiment of the is a configuration obtained by deleting the first housing 11a from the first embodiment of the fire hydrant device 10. 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.

[0101] Therefore, the fire extinguisher box 100 can secure the arrangement space for the terminal boxes 26a and 26b by the first housing 110a, and then thin down the width of the fire extinguisher box 100 to a predetermined width in the range of 180 to 200 mm corresponding to the outer diameter of the fire extinguisher 72, enabling the installation of the fire extinguisher box 100 on the monitor passage 35 in the tunnel while minimizing the restriction on the passage width of the monitor passage 35.

[0102] Also, even in this embodiment, the arrangement order of the first housing 110a and the second housing 110b can be arbitrarily changed, and the second housing 110b may be connected to the right side of the first housing 110a.

[0103] [e. Second Embodiment of Fire Hydrant Device] The second embodiment of the fire hydrant device 10 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 one housing as the first housing 112a, and the third housing 11c is used as the second housing 112b.

[0104] As shown in the cross-sectional view of the internal structure of the fire hydrant device in Fig. 14(A) seen from above, the second embodiment of the fire hydrant device 10 is arranged in two parts, the first housing 112a and the second housing 112b, from right to left, and is connected and installed. Specifically, as shown in the cross-sectional view of the housing division structure of the fire hydrant device in Fig. 14(B) seen from above, the housing of the fire hydrant device 10 is divided into two parts, the first housing 112a and the second housing 112b, and the right side surface of the second housing 112b is connected and fixed to the left side surface of the first housing 112a by 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 a-a indicated by the broken line in Fig. 4 showing the front of the fire hydrant device 10 in the first embodiment.

[0105] The interior of the first housing 112a is divided into a valve storage section 50a, a hose storage section 50b, an electrical equipment storage section 50c, and a terminal box storage section 50d from the right side. A partition plate 84 is arranged between the hose storage section 50b and the electrical equipment storage section 50c. Further, a wire passing port is formed in the partition plate 84 for drawing in a wiring cable that is drawn into the valve storage section 50a from the outside and passes through the valve storage section 50a and the hose storage section 50b to the electrical equipment storage section 50c side.

[0106] The structures of the valve storage section 50a, the hose storage section 50b, the electrical equipment storage section 50c, and the terminal box storage section 50d of the first housing 112a, the devices to be arranged, 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.

[0107] Further, the interior of the second housing 112b becomes a fire extinguisher storage section 50e, and the structure of the fire extinguisher storage section 50e, the equipment to be arranged, and the door to be provided are basically the same as those in the first embodiment of the fire hydrant device 10.

[0108] Also, a cable rack for inserting a wiring cable is provided in the hose storage section 50b, and openings for use in, for example, opening the fire extinguisher door 16 of the second housing 112b and reaching into the terminal box storage section 50d of the first housing 112a from the second housing 112b side to release the fixing of the first door 18 and the second door 20 from the inside of the first housing 112a may be formed in each of the connection surfaces between the first housing 112a and the second housing 112b, but illustration thereof is omitted.

[0109] Also, in the second embodiment of the fire hydrant device 10, similarly to the first embodiment of the fire hydrant device 10, after securing the arrangement space for the terminal boxes 26a and 26b by the terminal box storage section 50d, the width of the fire hydrant device 10 can be reduced to a predetermined width in the range of 180 to 200 mm corresponding to the outer diameter of the fire extinguisher 72, enabling the installation of the fire hydrant device 10 on the monitor passage 35 in the tunnel while minimizing the restriction on the passage width of the monitor passage 35.

[0110] Also, even in this embodiment, the arrangement order of the first housing 112a and the second housing 112b can be arbitrarily changed, and it may be configured such that the second housing 112b is connected to the right side of the first housing 112a.

[0111] [f. Third Embodiment of 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 the first housing 114a, and the second housing 11b and the third housing 11c are the second housing 114b, which are made into one housing.

[0112] As shown in the cross-sectional view of the internal structure of the fire hydrant device in Fig. 15(A) seen from above, the third embodiment of the fire hydrant device 10 is arranged in two parts, namely the first housing 114a and the second housing 114b, from right to left, and is installed after being connected. Specifically, as shown in the cross-sectional view of the housing division structure of the fire hydrant device in Fig. 15(B) seen from above, the housing of the fire hydrant device 10 is divided into two parts, the first housing 114a and the second housing 114b, and the right side surface of the second housing 114b is connected and fixed to the left side surface of the first housing 114a by bolts 76 and nuts 78. Note that Fig. 15(A) is a cross-section of the fire hydrant device 10 in the third embodiment at the position a-a indicated by the broken line in Fig. 4 showing the front of the fire hydrant device 10 in the first embodiment.

[0113] The interior of the first housing 114a is divided from the right side into a valve storage part 50a and a hose storage part 50b. Regarding the structure of the valve storage part 50a and the hose storage part 50b, the equipment arranged, and the doors provided corresponding to the storage parts, they are basically the same as those in the first embodiment of the fire hydrant device 10.

[0114] The interior of the second housing 114b is divided from the right side into an electrical equipment storage part 50c, a terminal box storage part 50d, and a fire extinguisher storage part 50e, and a partition plate 84 is arranged between the terminal box storage part 50d and the fire extinguisher storage part 50e.

[0115] Regarding the structure of the electrical equipment storage part 50c, the terminal box storage part 50d, and the fire extinguisher storage part 50e in the second housing 114b, the equipment arranged, and the doors provided corresponding to each storage part, they are basically the same as those in the first embodiment of the fire hydrant device 10.

[0116] In addition, on each of the connecting surfaces between the first housing 114a and the second housing 114b, a wire passing hole is formed for drawing a wiring cable that has passed through the inside of the first housing 114a from the outside to the second housing 114b side. A cable rack for inserting the wiring cable is provided in the hose storage portion 50b. An opening may be formed in the partition plate 84 that partitions the terminal box storage portion 50d and the fire extinguisher storage portion 50e of the second housing 114b for use in, for example, opening the fire extinguisher door 16, reaching into the electrical equipment storage portion 50d from the fire extinguisher storage portion 50e, and releasing the fixing of the first door 18 and the second door 20 from the inside of the second housing 114b, but the illustration thereof is omitted.

[0117] Moreover, the third embodiment of the fire hydrant device 10, similar to the first embodiment of the fire hydrant device 10, secures the arrangement space for the terminal boxes 26a and 26b by the terminal box storage portion 50d, and then can reduce the thickness of the fire hydrant device 10 to a predetermined width in the range of 180 to 200 mm corresponding to the outer diameter of the fire extinguisher 72, enabling the installation of the fire hydrant device 10 on the monitor passage 35 in the tunnel while minimizing the restriction on the passage width of the monitor passage 35.

[0118] Also, in this embodiment, the arrangement order of the first housing 114a and the second housing 114b can be arbitrarily changed, and it may be configured such that the second housing 114b is connected to the right side of the first housing 114a.

[0119] [g. Embodiment of a fire hydrant device with electrical equipment and terminal boxes arranged vertically] An embodiment of a fire hydrant device with electrical equipment and terminal boxes arranged vertically will be described in more detail in the first embodiment of the fire hydrant device having a three-part housing split structure. Note that the configuration with the electrical equipment and terminal boxes arranged vertically can also be applied to the second and third embodiments of the fire hydrant device having a two-part housing split structure and the fire extinguisher box.

[0120] As shown in the front view of the fire hydrant device in FIG. 16, the fire hydrant device 10 is divided and arranged into a first housing 11a, a second housing 11b, and a third housing 11c from right to left, and adjacent housings are connected and installed.
