Description

[Technical Field]

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

[0002] Conventionally, in tunnels such as expressways and expressways, which are areas subject to firefighting, fire hydrant devices, which are a type of disaster prevention equipment storage device as shown in Figure 18, are generally installed along the length of the tunnel, for example, at intervals of 50 meters, by embedding boxes cut into the wall of the tunnel's main body. Note that Figure 18(A) shows the front of the fire hydrant device, and Figure 18(B) shows a cross section of the fire hydrant device as seen from above. Also, Figure 18(B) is a cross section indicated by the cutting line jj in Figure 18(A).

[0003] 18, the X, Y, and Z directions are perpendicular to each other. Specifically, as shown in FIGS. 18(A) and 18(B), when viewing the front face of the fire hydrant device from the front, the X direction is the left-right direction, the Y direction is the up-down direction, and the Z direction is the front-to-back direction. The +X side of the X direction is the right side, and the -X side is the left side. The +Y side of the Y direction is the top side, the -Y side is the bottom side, and the +Z side of the Z direction is the front side, and the -Z side is the rear side. This also applies to FIGS. 1 to 17, which are embodiments of the present invention.

[0004] 18, in a conventional fire hydrant device 10, a fire hose 60 and valves (not shown) are stored as fire hydrant equipment in a fire hydrant storage section 15a within a housing 111a equipped with a fire hydrant door 12 and a maintenance door 14 that can be opened and closed, and two fire extinguishers 72, for example, are stored in a fire extinguisher storage section 15b within a housing 111b equipped with a fire extinguisher door 16 and an electrical door 180. The electrical door 180 is provided with, as electrical equipment, for example, a red indicator light 22 that is supplied with AC 100V, a transmitter 24 that is supplied with DC 48V, a response lamp 25, a telephone jack 28 (inside the housing of the electrical door, see FIG. 4), and the like, and in cold regions, a space heater that is further supplied with AC 200V is installed.

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

[0006] However, in tunnels constructed using methods such as shield tunneling, the structure of the tunnel body makes it difficult to cut out a box in the tunnel wall and install a fire hydrant device by embedding it in place, due to the cost and effort involved, so the fire hydrant must be installed in an exposed position in the guard's passage.

[0007] Furthermore, in order to install the fire hydrant device on the tunnel wall surface without removing the box, a wall-mounted structure has been proposed in which the fire hydrant device is attached and fixed to a stand installed on the tunnel wall surface.In this case, the stand is composed of a main support part fixed to the wall surface and a position-maintaining member that maintains the position of the fire hydrant device (Patent Document 2).

[0008] Furthermore, since wall-mounted fire hydrant devices have issues such as the time and labor required to install them on the tunnel wall, it is being considered to use a so-called stationary structure in which the fire hydrant device is attached and fixed in an exposed state to a stand installed on the road surface of the guard passage, which is easier to install. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-055073 [Patent Document 2] Japanese Patent Application Publication No. 2020-078429 Summary of the Invention [Problem to be solved by the invention]

[0010] However, in the case of a fire hydrant device installed as a wall-mounted or freestanding structure, the width (front-to-back direction) of the guard passage is restricted by the installation of the fire hydrant device, and in order to ensure the width of the guard passage, it is necessary to make the width (front-to-back thickness) of the fire hydrant device as thin as possible.

[0011] When thinning the fire hydrant device 10 in this manner, 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, the width of the fire hydrant device 10 can be thinned to approximately 180 to 200 mm, while taking into consideration that the stored fire extinguisher 72 does not come into contact with the housing 111b.

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

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

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

[0015] (Fire hydrant equipment) The present invention provides A guard passageway was installed along the tunnel wall of a tunnel with a road. 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, The housing is a first housing in which the fire hydrant device is disposed; a second housing connected to a side portion of the first housing and housing an electrical device and a fire extinguisher; a third housing connected to an upper portion of the first and second housings, in which a terminal box is disposed; It consists of The wiring cable is drawn from the first housing to the third housing and connected to the terminal box, and another wiring cable connected to the terminal box and drawn out is drawn from the third housing to the second housing and connected to the electrical equipment.

[0016] (Door to the third cabinet) The third housing has a door that is supported so as to be freely opened and closed on the top surface or the front surface corresponding to the arrangement position of the terminal box.

[0017] (Third enclosure wiring) In the third housing, a plurality of wiring paths are formed between the lead-in position of the wiring cable from the first housing and the terminal box, the wiring paths being divided in the depth direction by partition members.

[0018] (Opening between the first and second housings and the third housing) An opening for inserting a wiring cable is formed between the first housing, the second housing, and the third housing; An elastic closing member can be installed in the opening, which closes the opening and has a cutout formed therein for inserting a wiring cable within a predetermined range in the arrangement direction of the first and second housings.

[0019] (The terminal box is located on the back of the door of the third housing.) The third housing has a terminal box disposed on the rear surface of a door that is supported so as to be freely opened and closed, and the wiring cable can be connected with the door open to expose the terminal box.

[0020] (Position of the door where the terminal box is located) The door with the terminal box arranged on the back side is a front door supported at a predetermined position on the front surface of the third housing so as to be able to open sideways, or an upper door supported at a predetermined position on the top surface of the third housing so as to be able to open upwards.

[0021] (4th enclosure for wiring cables) A fourth housing is provided between the first housing, the second housing and the third housing, forming a path for the wiring cable.

[0022] (4th enclosure wiring) In the fourth housing, a plurality of wiring paths are formed between the lead-in position of the wiring cable from the first housing and the terminal box arranged in the third housing, the wiring paths being divided in the depth direction by partition members.

[0023] (Opening between the first and second housings and the fourth housing) openings for inserting a wiring cable are formed between the first housing and the fourth housing, and between the fourth housing and the third housing, and An elastic closing member can be installed in the opening, which closes the opening and has a cutout formed therein for inserting a wiring cable within a predetermined range in the arrangement direction of the first and second housings.

[0024] (Width of the housing) The housing has a predetermined width corresponding to the outer diameter of the fire extinguisher.

[0025] (Installation and fixing of the enclosure on a stand above the guard passage) The housing is attached and fixed to the top of a stand installed on the road surface of the guard passageway, close to the tunnel wall.

[0026] (Installation and fixing of the enclosure on a stand on the tunnel wall) The housing is attached and fixed to the front part of the platform, which is on the road side, installed on the tunnel wall above the road surface of the guard passage.

[0027] (Fire hydrant system without fire extinguisher) Another aspect of the present invention is A guard passageway was installed along the tunnel wall of a tunnel with a road.A fire hydrant device in which a fire hydrant device, an electrical device, and a terminal box are arranged in a housing, The housing is a first housing in which the fire hydrant device is disposed; a second housing connected to a side portion of the first housing and in which electrical equipment is disposed; a third housing connected to an upper portion of the first and second housings, in which a terminal box is disposed; It consists of The wiring cable is drawn from the first housing to the third housing and connected to the terminal box, and another wiring cable connected to the terminal box and drawn out is drawn from the third housing to the second housing and connected to the electrical equipment.

[0028] (4th enclosure for wiring cables) A fourth housing is provided between the first housing, the second housing and the third housing, forming a path for the wiring cable. [Effects of the Invention]

[0029] (Effects of the fire hydrant device of the first invention) According to the fire hydrant device of the present invention, the housing is composed of a first housing in which the fire hydrant equipment is placed, a second housing connected to the side of the first housing in which the electrical equipment and fire extinguisher are placed, and a third housing connected to the top of the first and second housings in which the terminal box is placed.Therefore, the third housing ensures the space for placing the terminal box and the wiring space for the wiring cable connected to the terminal box, which were factors that made it difficult to make conventional fire hydrant devices thin, and the fire hydrant device can be made thin without being restricted by these spaces.

[0030] In addition, since the wiring cable is pulled from the first housing to the third housing and connected to the terminal box, and another wiring cable connected to the terminal box and pulled out is pulled from the third housing to the second housing and connected to the electrical equipment, it is possible to shorten the wiring length of the wiring cable compared to conventional fire hydrant devices in which the terminal box was located behind the fire extinguisher placed in the same housing as the electrical equipment, making it easier to route the wiring.

[0031] In addition, the upper side of the fire hydrant device housing, which is placed exposed at a specified height in the guard passage, is an open space with no restrictions, so a third housing can be installed above the first and second housings without being restricted by the tunnel structure.

[0032] (Effect of the door on the third cabinet) Furthermore, the third housing has a door that is supported on the top or front surface so that it can be opened and closed freely, corresponding to the position of the terminal box, making it possible to simply and easily open the door of the third housing at the installation site of the fire hydrant device and pull the wiring cable from the first housing to connect it to the terminal box.In addition, during the assembly and manufacturing stage of the fire hydrant device, the work of pulling the wiring cable connected to the electrical equipment from the second housing into the third housing and connecting it to the terminal box can also be simply and easily done by opening the door of the third housing.

[0033] (Effect of the wiring in the third enclosure) In addition, the third housing has multiple wiring paths separated in the depth direction by partition members between the wiring cable pull-in position from the first housing to the terminal box.For example, if separate terminal boxes for high voltage and low voltage are provided in the third housing, two wiring paths will be formed, and by passing the high voltage cable through one wiring path and the low voltage cable through the other wiring path, the high voltage cable and the low voltage cable can be reliably separated by the maximum physically possible distance, thereby reducing the impact of noise from the high voltage cable on the low voltage cable used for signal communication, etc.

[0034] (Effect of openings between the first and second housings and the third housing) An opening for inserting a wiring cable is formed between the first and second housings and the third housing, and an elastic closing member can be installed in the opening to close the opening and to have a notch formed in it for inserting the wiring cable within a predetermined range in the aligned direction of the first and second housings.Therefore, the wiring inserted into the notch formed in the opening is held in place by clamping with elastic force, making it easy to insert and remove the wiring cable from the third housing and also making it possible to easily change the position at which it is inserted and removed.

[0035] (Effect of the structure where the terminal box is located on the backside of the door of the third housing) In addition, the third housing has a terminal box arranged on the backside of a door that is supported so that it can be opened and closed freely, and the wiring cable can be connected with the door open to expose the terminal box.For example, the door with the terminal box arranged on the backside is a front door that is supported at a predetermined position on the front of the third housing so that it can be opened sideways, or an upper door that is supported at a predetermined position on the top surface of the third housing so that it can be opened upwards.When the door is opened, the terminal box arranged on the backside of the door is exposed to the outside, making it possible to open the terminal box and connect the wiring cable simply and easily.

[0036] (Effect of the fourth enclosure for wiring cables) In addition, a fourth housing is provided between the first and second housings and the third housing to form a path for the wiring cables, and the fourth housing, which is separate from the third housing, functions as a cable rack for routing the wiring cables, making it possible to easily route the wiring cables between the first and second housings and the third housing.

[0037] (Effect of the wiring in the fourth enclosure) In addition, in the fourth housing, multiple wiring paths separated in the depth direction by partition members are formed between the wiring cable pull-in position from the first housing to the terminal box located in the third housing.Therefore, for example, by forming two wiring paths and passing a high-voltage cable through one wiring path and a low-voltage cable through the other wiring path, the high-voltage cable and the low-voltage cable can be reliably separated by the maximum physically possible distance, thereby reducing the impact of noise from the high-voltage cable on the low-voltage cable used for signal communication, etc.

[0038] (Effect of openings between the first and second housings and the fourth housing) In addition, openings for inserting wiring cables are formed between the first and second housings and the fourth housing, and between the fourth housing and the third housing, and an elastic closing member can be installed in the openings to close the openings and to have a notch formed in it for inserting the wiring cables within a predetermined range in the direction in which the first and second housings are aligned.As with the opening in the third housing, the wiring that passes through the notch formed in the opening is held in place by being clamped by elastic force, making it easy to insert and remove the wiring cables from the fourth housing and also making it possible to easily change the position at which they are inserted and removed.

[0039] (Width of the housing) Furthermore, since the housings including the first to fourth housings have a predetermined width corresponding to the outer diameter of the fire extinguisher, it is possible to thin the housing of the fire hydrant device to, for example, approximately 180 mm to 200 mm, making it possible to make it 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.

[0040] (Effect of fixing the enclosure to the stand above the guard passage) In addition, the housing is attached and fixed to the top of a stand installed on the road surface of the guard passage, close to the tunnel wall. This, combined with the fact that the fire hydrant device is made thinner, makes it possible to install the fire hydrant device while minimizing restrictions on the passage width of the guard passage.

[0041] (Effect of fixing the enclosure to the stand on the tunnel wall) Furthermore, since the housing is attached and fixed to the front part facing the road of the stand installed on the tunnel wall above the road surface of the guard passage, even though it is a wall-mounted structure, this, combined with the fact that the fire hydrant device has been made thinner, makes it possible to install the fire hydrant device while minimizing restrictions on the passage width of the guard passage.

[0042] (Effects of the fire hydrant device of the second invention) Another form of the present invention is directed to a fire hydrant device in which a fire extinguisher is not placed inside the housing, but rather a fire hydrant device, electrical equipment, and a terminal box are placed inside the housing, and since it provides the same effects as the fire hydrant device of the first invention described above, a description of it will be omitted.

DETAILED DESCRIPTION OF THE INVENTION

[0044] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a fire hydrant device according to the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments.

[0045] [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.

[0046] Here, a "fire hydrant device" is a type of emergency equipment installed in areas subject to fire extinguishing, such as tunnels on expressways and motorways, and is a housing installed in the area subject to fire extinguishing, in which fire hydrant equipment such as fire hoses, electrical equipment such as red indicator lights and transmitters on electrical doors, terminal boxes, and fire extinguishers are arranged, and the concept includes fire hydrant facilities in which fire hydrant devices are installed.

[0047] In addition, the "placement" of the fire hydrant equipment, electrical equipment, terminal box, and fire extinguisher relative to the fire hydrant device is a concept that includes "storage."

[0048] The housing of the fire hydrant device of the present invention is composed of at least a first housing, a second housing, and a third housing.

[0049] The "first housing" is a box-shaped housing in which the fire hydrant equipment is placed. The "second housing" is a box-shaped housing connected to the side of the first housing in which the electrical equipment and fire extinguisher are placed. The "third housing" is a thin box-shaped housing connected to the top of the first and second housings in which the terminal box is placed.

[0050] In a housing consisting of a first housing, a second housing, and a third housing, a wiring cable pulled into the first housing from the outside is further pulled into the third housing and connected to a terminal box, and another wiring cable connected to the terminal box and pulled out is pulled from the third housing into the second housing and connected to electrical equipment.

[0051] Here, "fire hydrant equipment" refers to specified equipment including fire hoses and valves such as fire hydrant valves, "electrical equipment" refers to specified equipment including red indicator lights, transmitters, answering lights and telephone jacks, and "terminal box" refers to a storage box equipped with a terminal block for connecting wiring cables, etc. that are pulled into the housing from outside the fire hydrant device to the electrical equipment.

[0052] The width of the housing refers to the depth of the housing in the front-to-rear direction, and is 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 to 200 mm, and refers to the length in the depth direction, not the height direction, which is approximately perpendicular to the left-to-right direction.

[0053] The fire hydrant device is installed in an exposed state at a predetermined height above the road surface of a guard passageway that is provided along the interior wall of a tunnel that has a road. Here, the "predetermined height" refers to a height that allows the fire hydrant device to be installed in a position close to or in contact with the tunnel wall, and can be installed at the predetermined height by, for example, attaching and fixing a housing to the top of a platform installed on the road surface of the guard passageway, or by attaching and fixing a housing to the front part of a platform installed on the tunnel wall above the road surface of the guard passageway, which faces the road.

[0054] Furthermore, the term "frame" refers to a structure that supports an object using pillars, beams, etc., and includes concepts such as a support base, foundation, base, pedestal, and base.

[0055] The fire hydrant device of the present invention will be described below in first to fourth embodiments. The first embodiment of the fire hydrant device has an upper door that is supported so as to be freely opened and closed on a surface of the third housing corresponding to the arrangement position of the terminal box, for example, on the top surface. Opening the upper door of the third housing makes it possible to simply and easily perform on-site work of pulling a wiring cable from the first housing to the third housing and connecting it to the terminal box, as well as work of pulling a wiring cable connected to electrical equipment during manufacturing from the second housing to the third housing and connecting it to the terminal box.

[0056] The third housing has a plurality of wiring paths separated in the depth direction by a partition member formed between the lead-in position of the distribution cable from the first housing and the terminal box. The number of wiring paths is arbitrary, but for example, two wiring paths may be formed, and a high-voltage cable may be inserted into one wiring path and a low-voltage cable may be inserted into the other wiring path, thereby ensuring the maximum physically possible separation between the high-voltage cable and the low-voltage cable and reducing the impact of noise, etc. from the high-voltage cable on the low-voltage cable used for signal communication, etc.

[0057] An opening for inserting a wiring cable is formed at the bottom of the third housing, i.e., between the first and second housings and the third housing. An elastic closing member with a cutout for inserting the wiring cable can be installed in the opening, and when the elastic closing member is installed, the wiring inserted through the cutout is held in place by being clamped by elastic force, making it easy to insert and remove the wiring cable and also making it possible to easily change the position where the cable is inserted and removed.

[0058] In the second embodiment of the fire hydrant device, an upper door is disposed on a part of the surface corresponding to the position of the terminal box of the third housing, for example, on a part of the upper surface.

[0059] In a third embodiment of the fire hydrant device, a terminal box is disposed on the backside of a front door or an upper door that is supported on the front or top surface of the third housing so as to be able to open and close freely. When the terminal box is disposed on the backside of the front door, the terminal box disposed on the backside of the door is exposed to the outside when the front door is opened, and it becomes possible to open the terminal box and connect the wiring cable.

[0060] The fourth embodiment of the fire hydrant device has a fourth housing between the first and second housings and the third housing placed above them. The "fourth housing" is a box-shaped container that is thinner than the third housing, which forms the wiring path for the distribution cable, and has an open top, for example, and functions as a cable storage section or a cable rack.

[0061] The fourth housing has a plurality of wiring paths formed therein, separated in the depth direction by partition members. The number of wiring paths is arbitrary, but for example, two wiring paths may be formed, and a high-voltage cable may be inserted into one wiring path and a low-voltage cable may be inserted into the other wiring path, thereby ensuring the maximum physically possible separation between the high-voltage cable and the low-voltage cable and reducing the impact of noise, etc. from the high-voltage cable on the low-voltage cable used for signal communication, etc.

[0062] An opening is formed on the bottom surface of the fourth housing for inserting the wiring cable, and an elastic closing member with a notch formed therein for inserting the wiring cable can be installed in the opening.When the elastic closing member is installed, the wiring inserted through the notch is held in place by clamping it with elastic force, making it easy to insert and remove the wiring cable from the fourth housing and also making it possible to change the position at which it is inserted and removed.

[0063] Specific embodiments will be described below, divided into Embodiments 1 to 4. In the specific embodiments shown below, a case will be described in which "the fire hydrant device is attached and fixed to a stand installed above the guard passage in the tunnel" and the "terminal box" is "a terminal box for high voltage and low voltage."

Modifications of the present invention

[0065] [a. First embodiment of the fire hydrant device] The first embodiment of the fire hydrant device will be described in more detail. Figure 1 is an explanatory diagram showing the installation of the fire hydrant device according to the first embodiment inside a tunnel, with Figure 1(A) showing the installation of the fire hydrant device as seen from the tunnel cross section and Figure 1(B) showing the installation of the fire hydrant device as seen toward the tunnel wall. Figure 2 shows the fire hydrant device removed and with the upper door of the third housing open.

[0066] (a1. Overview of fire hydrant equipment) The fire hydrant device will now be described in more detail. As shown in Figures 1(B) and 2, the fire hydrant device 10 of the first embodiment is divided into, for example, a first housing 11a, a second housing 11b, and a third housing 11c.

[0067] The first housing 11a accommodates predetermined fire hydrant equipment, including fire hoses and valves such as fire hydrant valves. The second housing 11b is connected to the left side of the first housing 11a, and accommodates electrical equipment and a fire extinguisher. The third housing 11c is connected to the top of the connected first and second housings 11a and 11b, and accommodates a terminal box. A wiring cable drawn into the first housing 11a from the outside is connected to the terminal box, and the wiring cable drawn out from the terminal box is connected to the electrical equipment arranged in the second housing 11b.

[0068] A decorative frame 13a is attached to the front of the first housing 11a and to the right of the front of the third housing 11c. The door opening of the decorative frame 13a is divided into upper and lower halves, with a forward-tilting door 12 that functions as a fire hydrant door and opens downward on hinges 12a located at the bottom of the door opening, and a maintenance door 14 that opens upward on hinges 14a located at the top of the door opening.

[0069] Decorative frames 13b are attached to the front of the second housing 11b and to the left side of the front of the third housing. A fire extinguisher door 16 that opens sideways to the left on hinges 16a is disposed on the left side of the door opening of the decorative frame 13b, and the interior of the fire extinguisher door 16 serves as a fire extinguisher storage section that can store, for example, two fire extinguishers. In addition, a viewing window 17 is provided below the fire extinguisher door 16, allowing the presence or absence of a fire extinguisher to be confirmed from the outside.

[0070] An electrical door 18 that opens sideways to the right on hinges 18a is located on the right side of the door opening in the decorative frame 13b. The electrical door 18 is provided with electrical equipment such as a red indicator light 22, a transmitter 24, and an answer lamp 25, and a telephone jack 28 is provided on the inside of the door.

[0071] The red indicator light 22 is always lit, allowing the installation location of the fire hydrant device 10 to be confirmed from a distance. When a fire breaks out and the transmitter 24 is pressed to turn on the push button switch, a transmission signal is sent, which is received by a disaster prevention receiving panel installed in an electrical room or the like 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.

[0072] The third housing 11c is a thin box-shaped container having a width (width in the left-right direction) equal to the width of the first housing 11b and the second housing 11b connected together, and a height sufficient to store a terminal box, and functions as a terminal box storage section. An upper door 75 is disposed on the top surface of the third housing 11c, and opens upward via a hinge 76, with the upper edge on the tunnel wall side as the axis. Opening the upper door 75 of the third housing 11c makes it possible to connect a wiring cable to the terminal box located at the bottom of the housing.

[0073] (a2. Installation of fire hydrant equipment) The installation of fire hydrant equipment in tunnels will be explained in more detail below. As shown in Figure 1, a road 36 is constructed in the longitudinal direction (left and right direction) of the tunnel below the cylindrical (circular cross section) tunnel body constructed using the shield tunneling method, and a guard passage 35 is constructed at a predetermined height above the road 36 below the tunnel wall 26 along the rear side of the road 36.

[0074] Since it is difficult to cut out a box from the tunnel wall 26 constructed by the shield tunneling method to install the fire hydrant device 10, a mount 30 is installed on the road surface of the monitor's passage 35 close to the tunnel wall 26, and a housing composed of a first housing 11a, a second housing 11b, and a third housing 11c is attached and fixed to the mount 30, thereby installing the fire hydrant device 10. Here, the height H1 of the mount 30 is set so that the height from the road surface of the monitor's passage 35 to the transmitter 24 installed in the fire hydrant device 10 is within the legally specified range of 800 mm to 1500 mm. Furthermore, the side shape of the mount 30 in this embodiment is an inverted trapezoid with the top side longer than the bottom side, and the rear side is a downwardly sloping surface that follows the curved shape of the tunnel wall 26.

[0075] (a3. Installation height and thinness of fire hydrant equipment) The installation height and thinness of the fire hydrant device will be explained in more detail below. In order to reduce the restriction on the passage width caused by the protrusion (projection) of the fire hydrant device 10, which is installed on the road surface of the guard passage 35 by the mount 30, from the tunnel wall surface 26, the installation height of the fire hydrant device 10 has been optimized, and at the same time, the fire hydrant device 10 has been made as thin as possible.

[0076] First, since the installation height of the fire hydrant device 10 is determined by the mounting base 30, we will explain in more detail how to optimize the height H1 of the mounting base 30. Figure 3 shows a schematic diagram of the installation state of the fire hydrant device in the cross section of a tunnel.

[0077] 3(A), the height H1 of the mounting base 30 is set so that the horizontal housing center line SL2 passing through the center of the height direction of the fire hydrant device 10 installed on the guard passage 35 is as close as possible to the 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.

[0078] 3(B) shows a case where the height H1 of the mount 30 is set so that the housing center line SL2 coincides with the tunnel center line SL1. In this case, the degree to which the fire hydrant device 10 protrudes from the tunnel wall surface 26 can be minimized. However, the height H1 of the mount 30 should be adjusted within the possible range, taking into account factors such as the ease of removing the fire extinguisher.

[0079] Next, a more detailed explanation will be given of how the fire hydrant apparatus 10 can be made thinner. Of the devices housed in the fire hydrant apparatus 10, the fire extinguisher housed in the second housing 11b has the largest size in the front-to-rear direction (the direction of the width of the housing), and if the width (length in the front-to-rear direction) of the fire hydrant apparatus is a dimension that allows the fire extinguisher to be housed in the second housing 11b, the fire hydrant apparatus 10 can be made thinner, so the width (depth of the housing in the front-to-rear direction) of the fire hydrant apparatus 10 is set to a predetermined width that corresponds to the outer diameter of the fire extinguisher housed in the second housing 11b.

[0080] The outer diameter of the fire extinguisher is about 150 to 160 mm, and if a gap is secured so that the stored fire extinguisher does not come into contact with the second housing 11b, the minimum width of the fire hydrant device 10 is, for example, within a range of about 180 to 200 mm, and the width of the fire hydrant device 10 is set to a predetermined width within that range. In contrast, the width of a conventional fire hydrant device 10 that is installed by cutting a box out of the wall surface of a tunnel body and embedding it in place is about 300 mm, so the width of the fire hydrant device 10 of this embodiment can be made two-thirds or less of the conventional one, allowing the fire hydrant device 10 to be made thinner.

[0081] (a4. Configuration compatible with thinner fire hydrant devices) If the fire hydrant device 10 is made thin to a predetermined width in the range of approximately 180 to 200 mm to correspond 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 at the rear of the fire extinguisher storage section where the fire extinguisher is stored, as in the conventional fire hydrant device 10 shown in Figure 18.

[0082] Therefore, in this embodiment, in addition to the first housing 11a and the second housing 11b, the upper part of the first housing 11a and the second housing 11b can be used as empty space, so a third housing 11c is newly placed there, and instead of placing the terminal boxes 26a and 26b in the second housing 11b where the fire extinguisher is placed, the terminal boxes 26a and 26b are placed in the third housing 11b.

[0083] [b. Fire hydrant system structure] The structure of the fire hydrant device using a housing made up of a first housing 11a, a second housing 11b, and a third housing 11c will be described in more detail with reference to FIGS.

[0084] (b1. Structure of the first and second housings) The structures of the first housing 11a and the second housing 11b will be described in more detail. In this description, reference will be made to Fig. 4, which shows the internal structure of the fire hydrant device from the front with the hydrant door and maintenance door open, Fig. 5, which shows the internal structure of the fire hydrant device in a cross section viewed from above, and Fig. 6, which shows the hose storage section of the first housing in a cross section viewed from the right side. Of these, Fig. 5 is a cross section indicated by the cutting line aa in Fig. 4, and Fig. 6 is a cross section indicated by the cutting line bb in Fig. 4.

[0085] The interior of the first housing 11a 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 hydrant 52. The water supply pipe 48 also branches downward, and at the end of the branch, a fire hydrant valve 54 and an automatic pressure regulating valve 56 are provided, followed by a shape-retaining fire hose 60.

[0086] The hydrant valve 54 is opened and closed by a hydrant valve opening / closing lever 58, and when the hydrant valve opening / closing lever 58 is opened or closed, the hydrant valve 54 is remotely opened or closed by a known wire link mechanism. When the hydrant valve opening / closing lever 58 is opened or closed, a pump start interlock switch provided on the operation box turns on or off. In addition, a pump start switch 64 for use by the fire brigade is provided on the upper right of the hydrant 52.

[0087] 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 state of being wound inward clockwise or counterclockwise. Here, the hose storage frame 62 has a wider width to accommodate the wider width of the first housing 11a that accompanies the slimming of the fire hydrant device 10, and it is possible to store the fire hose 60 of the same predetermined length as in conventional fire hydrant devices with fewer windings than in conventional fire hydrant devices. In addition, a nozzle 68 is attached to the tip of the fire hose 60 pulled out through the hose guide 66, and the nozzle 68 is detachably held in a nozzle holder 70.

[0088] The interior of second housing 11b forms fire extinguisher storage section 50c, and two fire extinguishers 72 are stored behind fire extinguisher door 16, which opens laterally to the left on hinges 16a. Also, to the right of fire extinguisher door 16 is located electrical equipment door 18, which opens laterally to the right on hinges 18a. On electrical equipment door 18, from top to bottom, are located red indicator light 22, transmitter 24, telephone jack 28, and answer lamp 25, and telephone jack 28 is located inside electrical equipment door 18.

[0089] Here, of the electrical equipment, the red indicator light 22 has the largest size in the front-to-rear direction inside the second housing 11b, and its size is approximately 120 mm. Therefore, even if the fire hydrant device 10 is thinned to a predetermined width in the range of approximately 180 to 200 mm, each electrical equipment can be arranged while ensuring space for cable routing.

[0090] (b2. Structure of the third housing) The structure of the third housing will be described in more detail below. In this description, reference will be made to Fig. 7, which shows the third housing removed, Fig. 8, which shows the cable wiring of the third housing, Fig. 9, which shows the terminal box, Fig. 10, which shows the cable wiring system of the fire hydrant device, and Fig. 11, which shows the details of the wiring to the terminal box to which the low-voltage cable is connected. Of these, Fig. 7(B) is a cross section indicated by the cutting line cc in Fig. 7(A), and Fig. 8(B) is a cross section indicated by the cutting line dd in Fig. 8(A).

[0091] The third housing 11c is composed of a box-shaped main body 74 and an upper cover 75. The width of the box-shaped main body 74 is the length when the first housing 11a and the second housing 11b are connected together, and the depth is a predetermined width within a range of, for example, 180 mm to 200 mm corresponding to the outer diameter of the fire extinguisher, just like the first housing 11a and the second housing 11b, and the height is set to a height that can accommodate a terminal box.

[0092] The upper door 75 is arranged to open upward at the top opening of the box-shaped main body 74 by means of hinges 76 at, for example, three locations. Also, mounting holes 78 are formed at, for example, three locations on the front edge side of the upper door 75, and screw holes 80 are formed at positions that face each other when the door of the box-shaped main body 74 is closed, so that the upper door 75 can be fixed in the closed position by screws. Note that the opening / closing structure and closing structure of the upper door 75 are not limited to those described above and are arbitrary.

[0093] Terminal boxes 26a and 26b are arranged on the left and right sides of the bottom inside the box-shaped main body 74. Terminal box 26a is used to connect high-voltage wiring cables, and terminal box 26b is used to connect low-voltage wiring cables.

[0094] Here, terminal boxes 26a and 26b will be described in more detail. Figure 9 shows terminal box 26a arranged in third housing 11c, with Fig. 9(A) showing a top view of terminal box 26a, Fig. 9(B) showing a front view of terminal box 26a, and Fig. 9(C) showing a side view of terminal box 26a. The same applies to terminal box 26b.

[0095] Terminal box 26a is composed of box main body 260 and lid member 262, and its dimensions (length (top and bottom) x width (left and right) x depth (front and back)) when placed in third housing 11c are approximately 80 mm x 220 mm x 140 mm. Lid member 262 is disposed at the opening of box main body 260 so as to be able to open and close freely by hinge 264, and is fixed in the closed position by knob 268. When knob 268 is operated to release the fixation, lid member 262 is opened as shown by lid member 2620, and it becomes possible to connect a wiring cable to terminal block 280a.

[0096] Furthermore, the cover member 262 is made of a transparent resin so that the terminal block 280a inside can be seen. A plurality of waterproof connectors 266, for example, two on each of the top and side surfaces, are arranged on the top and side surfaces of the box main body 260, ensuring waterproofing of the wiring cables inserted into the waterproof connectors 266. Also, a terminal block 280a on which a plurality of terminals are arranged is arranged on the box main body 260.

[0097] 7, an opening 82 for inserting a wiring cable between the first housing 11a and the third housing 11c is formed in the bottom of the right end of the box-shaped main body 74. As shown in enlarged detail by the arrow, the opening 82 is closed by attaching an elastic closing plate 90, for example, by gluing it to the underside of the opening 82 formed in the bottom, and a cutout 84 is formed in the elastic closing plate 90 and penetrates it in the thickness direction.

[0098] The elastic closure plate 90 uses an elastomer (elastic polymer material), such as rubber (natural rubber, artificial rubber) or a resin-based elastomer (urethane rubber, silicone rubber, fluororubber, etc.). The cutout 84 formed in the elastic closure plate 90 makes it possible to insert a wiring cable into any position in the cutout 84, and the wiring cable inserted into the cutout 84 is held in the inserted position by the elastic restoring force of the elastic closure plate 90.

[0099] Furthermore, another opening 82 is formed in the bottom on the left side of the terminal box 26b of the box-shaped main body 74 for inserting a wiring cable between the second housing 11b and the third housing 11c, and like the right-side opening 82, it is closed by an elastic closing plate 90 having a cutout 84. The number of openings 82 in which the elastic closing plate 90 having the cutout 84 is installed is not limited to two, and any number and positions may be used as needed.

[0100] Furthermore, a partition plate 86 is arranged standing upright in the left-right direction between the opening 82 at the right end of the box-shaped main body 74 and the terminal box 26a. The partition plate 86 separates the interior of the box-shaped main body 74 into a first line path 88a on the rear side and a second line path 88b on the front side, allowing high-voltage cables and low-voltage cables to be physically separated and wired into the first line path 88a and the second line path 88b.

[0101] (b3. Fire hydrant device cable wiring system) The cable wiring system in the first housing 11a, the second housing 11b, and the third housing 11c of the fire hydrant device 10 will be described in more detail.

[0102] As shown in FIG. 10, the electrical door 18 of the second housing 11b is provided with electrical equipment such as a red indicator light 22, a transmitter 24, a response lamp 25, and a telephone jack 28, and the red indicator light 22 is connected to corresponding terminals of a terminal block 280a of a terminal box 26a arranged in the third housing 11c, and the transmitter 24, the response lamp 25, and the telephone jack 28 are connected to corresponding terminals of a terminal block 280b of a terminal box 26b arranged in the third housing 11c.

[0103] In addition, a pump start switch 64 and a pump start interlock switch 65 are provided in the valve storage section 50a in the first housing 11a of the fire hydrant device 10, and are connected to the terminal block 280b of the terminal box 26b arranged in the third housing 11c.

[0104] A high-voltage cable 53 supplied with AC 100V power from outside is pulled into the valve storage section 50a of the first housing 11a, and the high-voltage cable 53 is further pulled toward the third housing 11c and connected to the terminal of the terminal block 280a of the terminal box 26a arranged in the third housing 11c, and is then connected to the red indicator light 22 arranged on the electrical door 18 of the second housing 11b.

[0105] In addition, a low-voltage cable 55 (which is a single multi-core cable but is represented in the cable wiring system of Figure 10 as a telephone cable 55a, an answer lamp cable 55b, a transmitter cable 55c, and a switch cable 55d) which is a multi-core cable supplied with DC 48V power from outside is drawn into the bulb storage section 50a of the first housing 11a, and the low-voltage cable 55 is further drawn into the third housing 11c and connected to the terminal of the terminal block 280b of the terminal box 26b arranged in the third housing 11c, thereby being connected to the telephone jack 28, answer lamp 25, and transmitter 24 arranged in the electrical door 18 of the second housing 11b.

[0106] In addition, the switch cable 57 connected to the pump start switch 64 and the pump start interlock switch 65 provided in the valve storage section 50a of the first housing 11a is pulled into the third housing 11c and connected to the terminal of the terminal block 280b of the terminal box 26b, and is thereby connected to the transmitter 24 arranged in the electrical door 18 of the second housing 11b.

[0107] 10, the pump start switch 64 and the pump start interlocking switch 65 of the valve storage section 50a are connected to the terminals of the terminal block 280b of the terminal box 26b as a parallel circuit in which the wiring of the pump start interlocking switch 65 is connected to the terminal part of the pump start switch 64. Furthermore, the terminal of the terminal block 280b of the terminal box 26b to which the wiring of the pump start switch 64 and the pump start interlocking switch 65 are connected is connected to the terminal to which the wiring of the transmitter 24 is connected via a crossover wiring, so that the wiring of the pump start switch 64 and the pump start interlocking switch 65 is connected to the wiring of the transmitter 24.

[0108] Figure 8 shows the cable wiring in third housing 11c corresponding to the cable wiring system in Figure 10. High-voltage cable 53 drawn in from opening 82 at the right end of third housing 11c passes through first line 88a on the far side separated by partition plate 86 and is connected to high-voltage terminal box 26a. Also, low-voltage cable 55 and switch cable 57 drawn in from opening 82 at the right end pass through second line 88b on the near side separated by partition plate 86 and are connected to low-voltage terminal box 26b.

[0109] By passing the high-voltage cable 53 through the first line 88a and the low-voltage cable 55 and switch cable 57 through the second line 88b in this manner, the high-voltage cable 53 and the low-voltage cable 55 and switch cable 57 can be reliably separated by the maximum physically possible distance, thereby reducing the impact of noise and the like from the high-voltage cable 53 on the low-voltage cable 55 and switch cable 57 used for signal communications, etc.

[0110] The high-voltage cable 53 drawn out from the terminal box 26a is led into the second housing 11b through an opening 82 on the left side of the box-shaped main body 74 and connected to the red indicator light 22 on the electrical door 18. In addition, the switch cables 57 from the pump start switch and interlock switch are led into the third housing 11c through an opening 82 on the right side of the box-shaped main body 74 and connected to the terminal box 26b through the second wiring 88b. In addition, the low-voltage cable 55 and switch cable 57 drawn out from the terminal box 26b are led into the second housing 11b through an opening 82 on the left side of the box-shaped main body 74 and connected to the transmitter 24, answer lamp 25, and telephone jack 28 on the electrical door 18.

[0111] [c. Second embodiment of the fire hydrant device] The second embodiment of the fire hydrant device will be described in more detail below with reference to Fig. 12, which shows the second embodiment of the fire hydrant device having a door on part of the top surface of the third housing, and Fig. 13, which shows a plan view of the third housing removed from Fig. 12.

[0112] As shown in FIG. 12, in the second embodiment of the fire hydrant device 10, an upper door 75 that opens upward by a hinge 76 is arranged in, for example, a central door opening that is part of the upper surface of the third housing 11c that is arranged above the first housing 11a and the second housing 11b.

[0113] 13, the door opening in which the upper door 75 is disposed faces the terminal boxes 26a, 26b disposed inside the box-shaped main body 74 and openings 82 formed in the bottom on both sides thereof, and the upper door 75 can be opened to allow wiring of the wiring cables to the terminal boxes 26a, 26b. Note that the third embodiment is the same as the first embodiment except that no partition plate is provided between the terminal box 26a and the opening 82 on the right side of the box-shaped main body 74 through which the wiring cables are pulled in from the first housing 11a, and therefore a description thereof will be omitted. By providing the upper door 75 on a portion of the top surface of the third housing 11c in this way, the size of the upper door 75 can be reduced, and the door structure can be simplified.

[0114] [d. Third embodiment of the fire hydrant device] A third embodiment of the fire hydrant device will be described in more detail. In this description, reference will be made to Fig. 14, which shows a third embodiment of the fire hydrant device equipped with a front door on a third housing, and Fig. 15, which shows a plan view of the third housing removed from Fig. 14. Of these, Fig. 15(B) is a cross section indicated by the cutting line ee in Fig. 15(A), and Fig. 15(C) is a cross section indicated by the cutting line ff in Fig. 15(A).

[0115] As shown in Figure 14, in the third embodiment of the fire hydrant device 10, a first front door 92a and a second front door 92b that open sideways are arranged in the center of the front of the third housing 11c, which is arranged above the first housing 11a and the second housing 11b.

[0116] As shown in Figures 15(A), (C), and (D), the first front door 92a and the second front door 92b open sideways to the left and right using hinges 95 on both sides, and in the closed state shown in Figure 15(A), they are fixed in the closed position by, for example, tightening a lock screw 93 on the door mating surface.

[0117] As shown in Fig. 15(B), on the back surface of the first front door 92b, the terminal box 26a is disposed by a mounting base 94. Therefore, as shown in Fig. 15(D), when the first front door 92a is opened, the terminal box 26a disposed on the back surface of the door is pulled out and exposed from the front opening, making it easy to perform the work of wiring the wiring cables to the terminal box 26a.

[0118] The same is true for the second front door, with terminal box 26b located on the back side of second front door 92b. When second front door 92b is opened, terminal box 26b located on the back side of the door is pulled out and exposed from the front opening, making it easy to wire wiring cables to terminal box 26b.

[0119] Furthermore, openings 82 are formed in the bottom of the third housing 11c corresponding to both sides of the front door opening, and notches 84 for inserting the wiring cables are formed by installing elastic closing plates 90, making it possible to pull the wiring cables between the first housing 11a and the second housing 11b with the first front door 92a and the second front door 92b open. Other structures and arrangements are similar to those of the first embodiment shown in Figures 7 to 11, and therefore description thereof will be omitted. Furthermore, in this embodiment, terminal boxes 26a, 26b are disposed on the rear surfaces of both front doors of the third housing 11c, but terminal boxes 26a, 26b may also be attached and fixed to the rear surface of the upper door 75 that opens upward as shown in Figures 2 and 11.

[0120] [e. Fourth embodiment of the fire hydrant device] The fourth embodiment of the fire hydrant device will be described in more detail. In this description, reference will be made to Fig. 16, which shows the fourth embodiment of the fire hydrant device equipped with a fourth housing, and Fig. 17, which shows the third and fourth housings of Fig. 16 in plan view. Of these, Fig. 17(B) is a cross section indicated by section line gg in Fig. 17(A), Fig. 17(C) is a cross section indicated by section line hh in Fig. 17(A), and Fig. 17(D) is a cross section indicated by section line ii in Fig. 17(A).

[0121] As shown in FIG. 16, in the fourth embodiment of the fire hydrant device 10, a fourth housing 11d is disposed between the first housing 11a, the second housing 11b and the third housing 11c.

[0122] As shown in FIG. 17(A), the fourth housing has a first housing 11a and a second housing 11b, and the inside of the fourth housing is a terminal box housing section. 50 A cable storage section 50e that forms a path for the wiring cable is formed between the third housing 11c and the third housing 11d. The cable storage section 50e also forms a cable rack through which the wiring cable is inserted from a predetermined inlet to an outlet.

[0123] Here, the third housing 11b is taken as an example of the third embodiment shown in Figures 12 and 13, but it may also be the third housing 11c of the first embodiment shown in Figures 7 and 8, or the third embodiment shown in Figures 14 and 15.

[0124] The fourth housing 11b that forms the cable storage section 50e is a thin box-shaped storage body that is open at the top, and its width and depth are the same as the combined width and depth of the first housing 11a and the second housing 11b and the width and depth of the third housing 11c.The height is arbitrary as long as it is capable of storing the wiring cable and has an appropriate bending radius for the cable, but is, for example, about several tens of mm.

[0125] The fourth housing 11d is connected and fixed to the tops of the first housing 11a and the second housing 11b, and is connected to the third housing arranged on top so as to be able to open upward by hinges 97 arranged at three locations on the opening end on the tunnel wall side, as shown in Figures 17(A), (B), and (D). In order to fix the third housing 11c to the top of the fourth housing 11d, screw holes 100 are formed in two locations on the inside front end of the top opening of the fourth housing 11d, as shown in Figure 17(D). Mounting holes 102 are formed in the bottom of the third housing 11c shown in Figure 17(C) corresponding to the screw holes 100, and the third housing 11c can be fixed by fastening screws through the mounting holes 102 and into the screw holes 100.

[0126] 17(D), a plurality of openings 82 are formed in the bottom surface of the fourth housing 11d at predetermined intervals in the left-right direction, and notches 84 are formed in the openings 82 by installing elastic closing plates 90. The three openings 82 on the right side allow for the passage of wiring cables between the fourth housing 11d and the first housing 11a, and the two openings 82 on the left side allow for the passage of wiring cables between the fourth housing 11d and the second housing 11b. The bottom surface of the fourth housing 11d becomes the upper surfaces (ceiling surfaces) of the first housing 11a and the second housing 11b, and the bottom surface of the third housing 11c becomes the upper surface (ceiling surface) of the fourth housing 11d.

[0127] Also, as shown in Figures 17(B) and (D), a partition plate 96 is arranged in an upright position in the left-right direction in the center of the depth direction of the bottom surface of the fourth housing 11d, dividing the cable storage section 50e into a first line path 98a on the back side and a second line path 98b on the front side.

[0128] The wiring work of the wiring cable using the fourth housing 11d will be described in more detail below. First, as shown in Fig. 17(C), the upper door 75 of the third housing 11c is opened by the hinge 76, and the screw fastened to the screw hole 100 of the fourth housing 11d through the mounting hole 102 at the bottom is removed. Then, the third housing 11c is opened by the hinge 97, and the top surface of the fourth housing 11d is exposed as shown in Fig. 17(D).

[0129] In this state, the high-voltage cable drawn into the first housing 11a is inserted through the opening 82 at the right end of the fourth housing 11d and drawn into the first line 98a. After passing through the first line 98a, it is drawn into the third housing 11c through the opening 82 at the right end shown in FIG. 17(C). Next, the third housing 11c is returned to above the fourth housing 11d, the upper door 75 is opened as shown in FIG. 17(C), and the high-voltage cable drawn into the fourth housing 11d is connected to the high-voltage terminal box 26a. The high-voltage cable drawn out from the terminal box 26a is then inserted, for example, through the central opening 82 and drawn into the lower fourth housing 11d, passed through the first line 98a of the fourth housing 11d, and drawn into the lower second housing 11b through, for example, the second opening 82 from the left, and connected to the red indicator light on the electrical door.

[0130] Similarly, the low-voltage cable drawn into the first housing 11a is inserted through the opening 82 at the right end of the fourth housing 11d and drawn into the second line 98b, and after passing through the second line 98b, is drawn into the third housing 11c through the central opening 82 shown in Fig. 17(C) and connected to the low-voltage terminal box 26b. Also, the low-voltage cable drawn out from the terminal box 26b is, for example, inserted through the opening 82 at the left end and drawn into the lower fourth housing 11d, passed through the second line 98b of the fourth housing 11d, and then, for example, inserted through the second opening 82 from the left and drawn into the lower second housing 11b, and connected to the transmitter, answer lamp, and telephone jack of the electrical door.

[0131] In this way, by disposing the fourth housing 11d that forms the cable storage section 50e (cable rack) between the first housing 11a, the second housing 11b, and the third housing 11c, the wiring of the wiring cables inside the third housing 11c is reduced. Also, by providing slack in the wiring cables inserted through the fourth housing 11d, it is possible to take the wiring cables in and out of the first housing 11a, the second housing 11b, and the third housing 11c, and it is possible to easily adjust the wiring length.

[0132] Furthermore, by passing the high-voltage cable 53 through the first line 98a of the fourth housing 11d and the low-voltage cable 55 through the second line 98b, the high-voltage cable 53 and the low-voltage cable 55 can be reliably separated by the maximum physically possible distance, thereby reducing the impact of noise and the like from the high-voltage cable on the low-voltage cable used for signal communication, etc.

[0133] [f. Modifications of the present invention] Modifications of the fire hydrant device according to the present invention will be described. In addition to the above-described embodiment, the fire hydrant device of the present invention includes the following modifications.

[0134] (Wall-mounted fire hydrant device) The above embodiment has been given as an example of a fire hydrant device with a stationary structure in which the housing is attached and fixed to the top of a stand installed on the road surface of the guard passageway, close to the tunnel wall, but this is not limited to this. Similarly, a wall-mounted fire hydrant device in which the housing is attached and fixed to the front part on the road side of a stand installed on the tunnel wall surface above the road surface of the guard passageway can also be used. By placing a third housing on top of the first and second housings and providing a terminal box, it is possible to make the fire hydrant device thinner without being restricted by the placement of the terminal box.

[0135] (Fire hydrant device without fire extinguisher storage compartment) In the above embodiment, a fire extinguisher storage section is provided in the second housing to store the fire extinguisher, but a fire hydrant device may also be provided in which only the electrical equipment is arranged in the second housing without providing a fire extinguisher storage section. In this case, too, a third housing in which a terminal box is arranged is connected to the top of the first housing in which the fire hydrant device is arranged and the second housing in which only the electrical equipment is arranged, and the third housing is the same as in the first to fourth embodiments described above.

[0136] (If the tunnel wall has a cross section other than a circular cross section) In the above embodiment, the tunnel cross-sectional shape is circular, but if the tunnel cross-section is other than circular, such as a tricentric circle, the present invention can be applied by taking the horizontal line at the position where the horizontal width of the tunnel cross-sectional shape is widest as the tunnel center line SL1 in the above explanation.

[0137] (Fire hydrant device structure compatible with thinning) In the fire hydrant device in the above embodiment, the width of the first and second housings is increased to accommodate the reduction in thickness of the fire hydrant device, thereby ensuring the internal volume that would have been reduced by the reduction in thickness. However, the vertical width of the first and second housings may also be increased to ensure the internal volume that would have been reduced by the reduction in thickness.

[0138] (L-shaped door) In the above embodiment, an upper door or a front door is provided on the third housing, but the upper door may be an L-shaped door that extends to the front of the third housing, and the L-shaped door may be opened upward around the upper edge on the tunnel wall side as an axis, thereby opening the front and top of the third housing.

[0139] (others) Furthermore, the present invention includes appropriate modifications that do not impair the objects and advantages thereof, and is not limited to the numerical values ​​shown in the above embodiments. [Explanation of symbols]
