[0010] Hereinafter, embodiments of a fire hydrant device according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

[0011] [Basic Concept of the Embodiment] First, a basic concept of each embodiment will be described. Each embodiment generally relates to a fire hydrant device.

[0012] A "fire hydrant device" is a device used for disaster prevention, specifically, a device that is installed inside a tunnel and is equipped, for example, with a fire detector, a reporting device, a panel surface, a supply means, and a hose storage section.

[0013] A "fire detector" is a device that detects fires by receiving light from a monitoring area in a tunnel through a light entrance part, and specifically, a device that is arranged with a light entrance part protruding from the panel surface toward the monitoring area. Here, the "light entrance part" is a component that allows external light to enter the light receiving part (detection element) in the fire detector, and is a part into which light can effectively enter in order for the fire detector to detect a fire (determine a fire). Note that "arrangement of the light entrance part protruding from the panel surface toward the monitoring area" is a concept that indicates, for example, that at least a part of the periphery of the light entrance part in the fire detector protrudes from the panel surface toward the monitoring area, so that the light entrance part is provided closer to the monitoring area than the panel surface. Note that the "monitoring area" is an area that is the target of fire detection by the fire detector, and specifically, the area inside the tunnel. Also, the "detection range" is an area in which the fire detector can effectively detect a fire, and the monitoring area is included in this detection range.

[0014] A "notification device" is a device that notifies information, and more specifically, a device in which at least a part of the notification device is exposed from the panel surface to the monitored area side. A "notification device" is, for example, a device that includes an operation unit or a display unit, and as an example, an electrically wired device, and is a concept that includes a red indicator light, a manual transmitter, and a response lamp, etc.

[0015] The "panel surface" is a surface facing the monitoring area, for example, at least a part of the surface of the fire hydrant device that faces the monitoring area side and is exposed to the monitoring area side. The specific configuration of the "panel surface" is arbitrary, and for example, it may be configured as a common panel surface on which both the fire detector and the notification device are arranged, or it may be configured as multiple panel surfaces on which the fire detector and the notification device are separately arranged. When the "panel surface" is configured as multiple panel surfaces on which the fire detector and the notification device are separately arranged, the panel surface on which the fire detector is arranged corresponds to the "first panel surface" and the panel surface on which the notification device is arranged corresponds to the "second panel surface". In the embodiment described later, the surface of the "panel unit" that faces the monitoring area side is the "panel surface", but for convenience of explanation, these are not distinguished and the "panel surface" may be referred to as the "panel unit".

[0016] The "supply means" is a component to which fire water is supplied from outside the fire hydrant device, and specifically, the concept includes piping for supplying fire water to the fire hose, as well as a water hydrant used by the fire brigade and piping for supplying water to the water hydrant. The supply means is a component provided on one side in the horizontal direction based on the horizontal center of the hose storage unit in the installed state of the fire hydrant device. The "installed state of the fire hydrant device" is a concept that indicates, for example, a state in which the fire hydrant device is installed in a tunnel. The "horizontal center of the hose storage unit" is the center of the hose storage unit, specifically, the center of the hose storage unit in the horizontal direction of the fire hydrant device, and an example will be illustrated and described in the following embodiment. The "hose storage unit" is a part that stores a fire hose for discharging the fire water supplied to the supply means.

[0017] The arrangement of the fire detector and the notification device is arbitrary as long as the fire detector and the notification device are provided in the vicinity of each other. "The fire detector and the notification device are provided in the vicinity of each other" means, for example, that the fire detector and the notification device are provided in relatively close positions to each other, and in the case where there are a plurality of notification devices, the concept indicates that the fire detector and at least one notification device are provided adjacent to each other. Note that "the fire detector and at least one notification device are provided adjacent to each other" includes, for example, the concept that the fire detector and at least one notification device are provided adjacent to each other in any direction of the fire hydrant device (for example, the horizontal direction or the vertical direction when the fire hydrant device is installed) without being sandwiched between any component of the fire hydrant device (for example, a hose storage unit, etc.).

[0018] The fire detector and the notification device may be arranged, for example, as follows. Specifically, in a case where the supply means is provided on one side in the horizontal direction based on the horizontal center of the hose storage section when the fire hydrant device is installed, the fire detector and the notification device may be provided on one side in the horizontal direction based on the horizontal center of the hose storage section, or on the other side in the horizontal direction based on the horizontal center of the hose storage section. The fire detector and the notification device may be provided at positions having different heights from each other in the vertical direction when the fire hydrant device is installed, for example.

[0019] The placement of the fire detector is also arbitrary, but for example, the fire detector may be placed on the upper side of the second panel surface, and the light entrance portion of the fire detector and at least a part of the portion other than the light entrance portion may be positioned at least closer to the monitored area than the first panel surface.

[0020] In addition, the outer shape of the components of the fire hydrant device may be configured so as not to be included in the effective visual field space for the light incident portion of the fire detector. The "effective visual field space" will be described later.

[0021] In the following embodiments, the reporting device is a red indicator light, a manual transmitter, and a response lamp. In particular, in the first to fourth embodiments, when the supply means is provided on one side based on the horizontal center of the hose storage section, the fire detector and the reporting device are provided on the other side, where the supply means is not provided, based on the horizontal center of the hose storage section, and in the fifth embodiment, the fire detector and the reporting device are provided on the same side, where the supply means is provided, based on the horizontal center of the hose storage section.

[0022] [Specific details of each embodiment] Next, the specific contents of each embodiment will be described. Note that the line indicated by the reference numeral 900 in the explanatory diagram of each embodiment indicates the center of the housing of the fire hydrant device in the height direction.

[0023] (Embodiment 1) First, a description will be given of embodiment 1. In this embodiment, the fire hydrant device includes a fire extinguisher storage unit that stores a fire extinguisher, and a fire detector is provided above the fire extinguisher storage unit in the vertical direction of the fire hydrant device.

[0024] (composition) First, the configuration of the fire hydrant device of this embodiment will be described. Fig. 1 is a diagram showing the installation state of the fire hydrant device, Fig. 2 is a front view of the fire hydrant device, Fig. 3 is a front view of the fire hydrant device with the fire hydrant door and the maintenance door open, and Fig. 4 is a side view of the fire hydrant device with the fire hydrant door and the maintenance door open. Fig. 1 shows a state seen from a cross section perpendicular to the direction in which vehicles travel in a tunnel. Fig. 4 shows a state in which a part of the side of the fire hydrant device 100 is broken so that the inside can be seen.

[0025] In each figure, the XYZ axes are mutually orthogonal, and the Z axis indicates the vertical direction (i.e., the longitudinal direction when the fire hydrant device 100 is installed), with the +Z direction being referred to as the upper side and the -Z direction being referred to as the lower side in the following description. The Y axis indicates the horizontal direction (i.e., the lateral or width direction when the fire hydrant device 100 is installed), with the +Y direction being referred to as one side and the -Y direction being referred to as the other side in the following description. The X axis indicates the front-rear direction (i.e., the depth direction when the fire hydrant device 100 is installed), with the +X direction being referred to as the front or front side and the -X direction being referred to as the back or rear side in the following description. The +X direction here corresponds to the "monitoring area side."

[0026] The fire hydrant device 100 is a device installed in a tunnel, for example, as shown in Fig. 1. This tunnel is provided with, for example, a road surface 91 on which vehicles and the like pass, a supervisor passage 92 on which supervisors pass, and a tunnel wall surface 93. Vehicles pass along the Y axis. In addition, the tunnel wall surface 93 is provided with, for example, a storage section 94 for storing the fire hydrant device 100. In addition, the tunnel is provided with an external pipe 95 for supplying fire water to the fire hydrant device 100. The fire hydrant device 100 is installed in the storage section 94, and the front side (+X direction) of the fire hydrant device 100 is exposed.

[0027] As shown in FIG. 2, the fire hydrant device 100 includes, for example, a housing 1, a fire detector 81A, a red indicator light 82A, a manual transmitter 83A, and a response lamp 84A.

[0028] (Configuration - Chassis) The housing 1 is the main body of the fire hydrant device 100, and specifically, forms the outer shape of the fire hydrant device 100. The specific configuration of the housing 1 is arbitrary, but for example, it is a box shape extending in the horizontal direction (Y-axis direction) in a plan view. In the example shown here, the housing 1 is box-shaped, but is not limited to this, and for example, the housing 1 may be configured as a frame body (i.e., only a framework) except for the front side (+X direction) of the housing 1. In addition, the housing 1 includes, for example, a fire extinguisher storage section 11, a fire hydrant section 12, and panel sections 1A1 and 1A2.

[0029] (Configuration - Housing - Fire extinguisher storage section) The fire extinguisher storage section 11 is a space for storing a fire extinguisher, and can be opened and closed by a fire extinguisher door 111. In this embodiment, a transparent window is provided in part of the fire extinguisher door 111, so that the fire extinguisher in the stored state can be viewed from the outside.

[0030] (Configuration - Housing - Fire hydrant section) The fire hydrant unit 12 is a space that houses the components of the fire hydrant device 100, and can be opened and closed by a fire hydrant door 121 and a maintenance door 122. In addition, the fire hydrant unit 12 includes a hose storage space 13 and a piping storage space 14, as shown in FIG.

[0031] (Configuration - Housing - Fire hydrant section - Hose storage space) The hose storage space 13 is the hose storage section described above, and specifically, is a space that stores the water-discharge hose 131, and is, for example, a space that is partitioned from the piping storage space 14 side by a partition wall 13A in the horizontal direction (Y-axis direction) and is also a space that is partitioned from the fire extinguisher storage section 11 side in Fig. 2 by a partition wall 13B. The approximate center of the width from the partition wall 13A to the partition wall 13B in the horizontal direction (Y-axis direction) is the storage section center 130, which is the horizontal center of the hose storage space 13. For convenience of explanation, this storage section center 130 is shown by a dashed line.

[0032] The water discharge hose 131 is a fire hose for discharging fire water supplied from the outside of the fire hydrant device 100 through the external pipe 95 and the fire hydrant connection port 142 to the internal pipe 141, and for example, has a nozzle 132 provided at one end and the other end connected to the internal pipe 141. The water discharge hose 131 is stored in a wound state in the hose storage space 13. When discharging water, the nozzle 132 is held and the water discharge hose 131 is pulled out, and water is discharged toward the target water discharge point.

[0033] (Configuration - Housing - Fire hydrant section - Pipe storage space) The piping storage space 14 is a space for storing the internal piping 141 and the like. The external piping 95 in FIG. 1 is connected to the fire hydrant connection port 142. Fire water is supplied from the external piping 95 to the internal piping 141 via the fire hydrant connection port 142 by a pump facility (not shown). The internal piping 141 is a pipe for supplying the fire water to the water discharge hose 131. The internal piping 141 and the fire hydrant connection port 142 constitute a "supply means" provided on one lateral side (+Y direction) based on the storage center 130. A plurality of fire hydrant devices are installed in the tunnel, for example, at intervals of 50 m, and one of these is equipped with a water supply hydrant 144 at an interval of 200 m. The water supply hydrant 144 supplies water for firefighting activities by the fire brigade. For example, when a fire discharge hose is connected to the water supply hydrant and the valve is opened by rotating the valve handle 148, and then the pump start switch 146 is started, a pump start signal is sent to a disaster prevention receiving panel (not shown) installed in a disaster prevention sensor or the like. When the disaster prevention receiving panel receives this signal, it starts and controls a pump (not shown) so that water for firefighting is supplied from the external pipe 95 to the water supply hydrant 144. Water for firefighting can be supplied from the external pipe 95 to both the discharge hose 131 and the water supply hydrant 144 (or to one selected) via a branch pipe. This branch pipe constitutes the internal pipe 141. The pump start switch 146 is normally located behind the maintenance door 122 and hidden so that it cannot be operated by general users. The water supply hydrant 144, the pump start switch 146, and the valve handle 148 in the fire hydrant device 100 equipped with such a water supply hydrant 144 also constitute the "supply means".

[0034] (Configuration - Chassis - Panel section) The panel units 1A1 and 1A2 are fixedly provided at positions avoiding the fire extinguisher door 111, the fire hydrant door 121, and the maintenance door 122 on the front side (+X direction) of the housing 1. The front side (+X direction) faces the tunnel, which is the monitored area, and is parallel to the YZ plane, and corresponds to the above-mentioned "panel surface." In particular, the front side (+X direction) surface of the panel unit 1A1 corresponds to the "first panel surface," and the front side (+X direction) surface of the panel unit 1A2 corresponds to the "second panel surface." In this embodiment, the panel units 1A1 and 1A2 are configured so that the surfaces on the monitored area side are substantially flush with the fire extinguisher door 111, the fire hydrant door 121, and the maintenance door 122. The panel units 1A1 and 1A2 may have a door structure similar to the fire hydrant door 121 and the maintenance door 122.

[0035] (Configuration - Fire detector) Fig. 5 is an enlarged view of a part of Fig. 4, and Fig. 6 is a cross-sectional view taken along line AA in Fig. 2. Note that, since a known fire detector can be applied to the fire detector 81A itself, some of the components (such as a member supporting the inclined base plate 814) are omitted in Fig. 6 for the sake of convenience of explanation. Also, since the fire detector 81A is symmetrical with respect to the center 820 of the fire detector 81A in the horizontal direction (Y-axis direction), only the components on the left side of the drawing will be described with reference numerals.

[0036] The fire detector 81A in FIG. 2 is a device that detects a fire occurring in the effective visual field space in FIG. 6 described later and transmits a fire detection signal to a disaster prevention receiving panel. The specific configuration of the fire detector 81A is arbitrary, but a part of it protrudes toward the front side (+X direction) of the fire hydrant device 100. The fire detector 81A is provided, for example, on the panel part 1A1 of the housing 1. That is, the fire detector 81A is disposed with a translucent part 812A described later protruding from an opening provided in the panel part 1A1 toward the monitoring area side (+X direction). The fire detector 81A is provided, for example, near the red indicator lamp 82A, the manual transmitter 83A, and the response lamp 84A, and is provided on the other side in the horizontal direction (-Y direction) of the storage part center 130 in FIG. 3 in the housing 1. The fire detector 81A is provided, for example, on the upper side (+Z direction) of the fire extinguisher storage section 11 in FIG. 2 in the vertical direction (in the Z-axis direction).

[0037] The fire detector 81A includes, for example, a main body 811, an outer cover 812, a main board 813, an inclined board 814, and a detection element 815 in FIG. 6. The main body 811 forms the outer shape of the fire detector 81A. The outer cover 812 forms the outer shape of the fire detector 81A together with the main body 811, and is light-shielding except for a part (light-transmitting part 812A), and includes the light-transmitting part 812A. The light-transmitting part 812A is a light entrance part that passes external light and causes the light to enter the inside of the outer cover 812, and is a part that is formed of, for example, any light-transmitting material (for example, sapphire glass, etc.). The main board 813 is a circuit board for controlling the fire detector 81A, and is parallel to the panel parts 1A1 and 1A2 of the housing 1. The inclined board 814 is a circuit board for receiving light of the fire detector 81A, and is inclined at a predetermined angle with respect to the main board 813. The detection element 815 is, for example, a pyroelectric element for detecting light from a fire, and is an element that selectively receives light incident from outside the outer cover 812 (monitoring area) through the translucent portion 812A of the outer cover 812 and an optical filter not shown, for example, infrared light in the CO2 resonance radiation wavelength band emitted from a combustion flame, and converts the received infrared energy into an electrical signal and outputs it.

[0038] The fire detector 81A can detect a fire occurring within the effective visual field space of FIG. 6 due to the configuration of the light-transmitting portion 812A and the detection element 815. The "effective visual field space" is a space in which the fire detector 81A can accurately detect a fire, that is, the detection range described above. Specifically, it is a space in which the generated light can effectively enter the light-transmitting portion 812A, and includes, for example, a space (monitoring area) in which fire monitoring is required, which is determined in advance based on the required specifications. The "effective incidence" is a concept indicating, for example, that light is incident with an intensity sufficient to accurately detect a fire in the fire detector 81A. In other words, when a fire flame occurs within the effective visual field space, the light of the flame is incident on the light-transmitting portion 812A of the fire detector 81A with an intensity sufficient to accurately detect the fire.

[0039] In addition, the "effective visual field space" is, for example, as shown in FIG. 6, a space in front (+X direction) of the detection limit surface 810B on the side of the fire detector 81A in a plan view, with the detection limit surface 810B as a boundary. The detection limit surface 810B is a surface that is a boundary between the effective visual field space and a space other than the effective visual field space (i.e., a space where light generated due to a fire may not be effectively incident on the light-transmitting portion 812A), and conventionally, the required specifications of the fire detector 81A generally require that the angle θ between the X-direction cross section (center cross section) passing through the center 820 of the fire detector and this boundary surface be 90 degrees. In this embodiment, θ is set to an angle slightly larger than 90 degrees. The detection limit surface 810A in front of the fire detector 81A is designed to intersect with the center cross section of the fire detector on the monitoring area side. By configuring the fire detector 81A in this way, the fire detector 81A can have an effective visual field space (detection range) of 180 degrees or more in the Y-axis direction, and can accurately detect a fire occurring in a monitoring area within the effective visual field space. Note that the fire detector 81A has an effective visual field space that covers, for example, a range of 50 m each on the left and right in the Y-axis direction (+Y, -Y directions) and 20 m in the X-axis direction (+X direction).

[0040] 6, the fire detector 81A is attached to the panel section 1A1 of the housing 1 by, for example, inserting and screwing a mounting bolt 811B into a through hole of a detector-side mounting section 811A, which is a part of the main body 811, and a screw hole of a housing-side mounting section 1B fixed to the panel section 1A1 of the housing 1. If necessary, a well-known spacer or the like may be used in accordance with the bolt length. Note that the method of attaching the fire detector 81A described here is an example, and any other method may be used for attachment.

[0041] (Configuration - Red indicator light) The red indicator light 82A in FIG. 2 is a notification device and a display unit, specifically, a device for displaying and informing the position of the fire hydrant device 100. The specific configuration of the red indicator light 82A is arbitrary, but for example, it includes a light source and a red cover member that transmits light from the light source to the monitoring area side, and the cover member is exposed to the monitoring area side. The red indicator light 82A is provided, for example, on the panel part 1A2 in the housing 1, and is provided on the other side in the horizontal direction (-Y direction) of the storage part center 130 in FIG. 3 in the housing 1. In addition, the red indicator light 82A is provided, for example, at a position at approximately the same height as the fire detector 81A in the vertical direction (gZ axis direction). Note that "at approximately the same height" here is a concept indicating that the exposed part of the red indicator light 82A and the protruding part of the fire detector 81A are at approximately the same height in the vertical direction (Z axis direction). In this case, if the height dimension of the display part of the exposed part of the red indicator light 82A is made smaller than the height dimension of the protruding part of the fire detector 81A, the visibility of the display part of the red indicator light 82A from the side (-Y direction) on which the fire detector 81A is installed will be impaired, so the height dimension of the display part of the red indicator light 82A may be made relatively larger than the height dimension of the protruding part of the fire detector 81A.

[0042] Also, the exposed portion of the red indicator light 82A protrudes, for example, toward the front side (+X direction) of the fire hydrant device 100. The amount of protrusion of the red indicator light 82A toward the front side (+X direction) is arbitrary, but for example, the protrusion amount is set to such an extent that the entire outer shape including the exposed portion of the red indicator light 82A does not enter at least the monitoring area, and more preferably does not enter the above-mentioned effective visual field space (detection range). By configuring in this way, for example, even if a fire occurs on one side in the lateral direction (+Y direction), the red indicator light 82A does not enter the effective visual field space, so the original fire detection performance of the fire detector 81A is not impaired.

[0043] (Configuration: Manual transmitter) The manual transmitter 83A in Fig. 2 is a notification device and an operation unit, specifically, a device for notifying the occurrence of a fire, a device for triggering the electrical transmission of a fire occurrence signal to a disaster prevention receiving panel installed in a disaster prevention center (not shown), and a device for electrically transmitting a fire occurrence signal to the disaster prevention receiving panel when pressed by a user. The specific configuration of this manual transmitter 83A is arbitrary, but for example, it includes a push button or the like. The manual transmitter 83A is provided, for example, on the panel section 1A2 of the housing 1, and is provided on the other side in the horizontal direction (-Y direction) of the storage section center 130 in Fig. 3 in the housing 1.

[0044] (Configuration - Response Lamp) The response lamp 84A in Fig. 2 is a notification device and a display unit, specifically, a device that notifies that a fire occurrence signal has been received by a disaster prevention receiving panel installed on the disaster prevention center side (not shown) and responded to. The specific configuration of this response lamp 84A is arbitrary, but for example, it includes a light source, etc. In addition, the response lamp 84A is provided, for example, on the panel part 1A2 of the housing 1, and is provided on the other side in the horizontal direction (-Y direction) of the storage section center 130 of the housing 1 in Fig. 3.

[0045] (Configuration: Wiring for fire detectors, red indicator lights, manual transmitters, and response lights) Next, the wiring work of the fire detector 81A, the red indicator light 82A, the manual transmitter 83A, and the response lamp 84A (hereinafter, these devices are referred to as "target devices") will be described. This wiring work is optional, so only an outline will be described. Specifically, a known terminal board or terminal block is provided at an arbitrary position (for example, in the first embodiment, the rear side (-X direction) of the fire detector 81A inside the housing 1), and conductive wires (for example, signal wires or power supply wires) electrically connected to each target device are wired to the terminal board or terminal block, so that the target device is electrically connected to a predetermined device (for example, a disaster prevention receiving board, etc.) via the terminal board or terminal block. Here, since each target device is provided near each other, it is possible to simplify the wiring work. The terminal board or terminal block is, for example, housed in a waterproof case to protect the connection part from dew drops, etc.

[0046] (operation) Next, the operation of the fire hydrant device 100 thus configured will be described. The red indicator lamp 82A constantly outputs red light from the exposed portion of the panel unit 1A2 to the monitoring area side, thereby displaying the position of the fire hydrant device 100 and informing the user. In addition, when a user who discovers a fire breaks out presses the manual transmitter 83A, a fire occurrence signal is transmitted to the disaster prevention receiving panel (manual notification). In addition, after the fire occurrence signal is received by the disaster prevention receiving panel, a response signal is transmitted from the disaster prevention receiving panel to the fire hydrant device 100, causing the response lamp 84A of the fire hydrant device 100 to light up. In addition, when a fire breaks out around the fire hydrant device 100, the fire detector 81A detects the fire and transmits a fire detection signal to the disaster prevention receiving panel (automatic notification). In addition, when a user in the vicinity of the fire hydrant device 100 performs a predetermined operation (for example, operating a switch lever provided separately from the pump start switch 146) to open the fire hydrant door 121 in FIG. 2 and discharge water, in response to this operation, fire water from the external piping 95 side in FIG. 1 is supplied to the discharge hose 131 via the fire hydrant connection port 142 and internal piping 141 in FIG. 3, and water can be discharged from the nozzle 132 of the discharge hose 131.

[0047] (Effects of the embodiment) Thus, according to this embodiment, the fire detector 81A, the red indicator light 82A, the manual transmitter 83A, and the response lamp 84A are provided in close proximity to one another, which, for example, simplifies the routing of wiring for the fire detector 81A, the red indicator light 82A, the manual transmitter 83A, and the response lamp 84A, thereby simplifying the wiring work and improving maintainability.

[0048] In addition, the internal piping 141 and the fire hydrant connection port 142 are provided on one horizontal side (+Y) with respect to the storage center 130 of the hose storage space 13, and the fire detector 81A, the red indicator light 82A, the manual transmitter 83A, and the response lamp 84A are provided on the other horizontal side (-Y) with respect to the storage center 130 of the hose storage space 13. This makes it possible, for example, to place the fire detector 81A, the red indicator light 82A, the manual transmitter 83A, and the response lamp 84A away from the internal piping 141 and the fire hydrant connection port 142, thereby making it possible to prevent leakage current from occurring on the fire detector 81A, red indicator light 82A, manual transmitter 83A, and response lamp 84A side due to water droplets or the like around the internal piping 141 and the fire hydrant connection port 142. Furthermore, in this embodiment, as shown in FIG. 3, the supply means is positioned relatively downward (-Z) of the housing 1 of the fire hydrant device 100, and the fire detector, notification device, and terminal board or terminal block as the wiring part are positioned relatively upward (+Z). This makes it possible to more reliably prevent water droplets, dew droplets, splashes, etc. from the supply means side from reaching the fire detector, notification device, and the associated electrical wiring parts and causing them to become wet and malfunction, etc., and therefore makes it possible to reliably prevent the fire detector and notification device, which should function at an early stage after the occurrence of a fire, from malfunctioning.

[0049] Furthermore, since the outer shape of the components of the fire hydrant device 100 (e.g., the red indicator light 82A) does not enter the effective field of view space for the translucent portion 812A of the fire detector 81A, it is possible to reliably detect a fire using the fire detector 81A, for example.

[0050] (Embodiment 2) Next, a second embodiment will be described. In this embodiment, the fire detector and the red indicator light are provided at different heights in the vertical direction. In the second embodiment, only the characteristic configuration of the present embodiment will be described, and the description of the same configuration as that described in the first embodiment will be omitted (the same applies to the other embodiments). Furthermore, each element of the second embodiment will be the same as the element of the same name in the first embodiment (the same applies to the other embodiments) unless otherwise specified.

[0051] (composition) The configuration of the fire hydrant device of this embodiment will be described. The wiring work and operation of the fire hydrant device of this embodiment are similar to those of the fire hydrant device 100 of embodiment 1, so the description will be omitted (the same applies to other embodiments). Figure 7 is a front view of the fire hydrant device, and Figure 8 is a front view of the fire hydrant device with the fire hydrant door and maintenance door open.

[0052] As shown in FIG. 1, the fire hydrant device 200 is installed in a tunnel in the same manner as the fire hydrant device 100 of embodiment 1, and as shown in FIG. 7, for example, includes a housing 2, a fire detector 81B, a red indicator light 82B, a manual transmitter 83B, and a response lamp 84B.

[0053] (Configuration - Chassis) The housing 2 includes, for example, a fire extinguisher storage section 21, a fire hydrant section 22, and a panel section 2A. Note that the front side (+X direction) surface of the panel section 2A corresponds to the "panel surface."

[0054] (Configuration - Housing - Fire hydrant section) As shown in FIG. 8, the fire hydrant unit 22 includes a hose storage space 23 and a piping storage space 24.

[0055] (Configuration - Fire detector) 7 is provided, for example, near the red indicator light 82B, the manual transmitter 83B, and the response lamp 84B, and is provided on the panel unit 2A, and is provided on the other side in the lateral direction (-Y direction) of the storage unit center 230 in the housing 2 in Fig. 8. The fire detector 81B is provided, for example, above the red indicator light 82B etc. in Fig. 7 (+Z direction).

[0056] (Consists of a red indicator light, a manual transmitter, and an answer lamp) The red indicator light 82B, the manual transmitter 83B, and the response lamp 84B in Fig. 7 are notification devices, and are provided, for example, on the panel unit 2A, and are provided on the other side in the horizontal direction (-Y direction) of the storage unit center 230 in Fig. 8 in the housing 2. At least the red indicator light 82B (the entire notification device in the form of Fig. 7) among the notification devices is provided at a position different in height from the fire detector 81B in the vertical direction (Z-axis direction), and at least a part (the entirety in the form of Fig. 7) of the display part of the exposed part of the red indicator light 82B (the length from the top to the bottom in the Z direction) is arranged so as not to overlap with the protruding part of the fire detector 81B in the height direction, that is, in a side view (when viewed from the +Y or -Y side), at least a part of the display part of the exposed part of the red indicator light 82B is arranged so as not to overlap with the protruding part of the fire detector 81B in the height direction (Z-axis direction).

[0057] 7, the red indicator lamp 82B is disposed below (-Z direction) the center 900 in the height direction (Z-axis direction) of the housing 2, but it is more preferable to dispose it above (+Z direction) the center 900. In this case, the relative positions of the manual transmitter 83B and the response lamp 84B may be adjusted, but from the viewpoints of operability, visibility, and providing electrical components in close proximity to each other, it is preferable to dispose the manual transmitter 83B and the response lamp 84B as close to the upper side (+Z direction) as possible without causing any hindrance, regardless of the illustrations in FIGS. 7 and 8. This is also true for the other embodiments.

[0058] (Effects of the embodiment) Thus, according to this embodiment, it is possible to improve the visibility of the red indicator light 82B from the side of the fire hydrant device 200. Since each notification device is disposed below (-Z direction) the fire detector 81B, even if any notification device protrudes slightly from the panel section 2A, the fire flame rising upward from the road surface 91 is within the effective visual field space of the fire detector 81B, and no blind spot is created in the side of the fire detector, so that the fire can be detected reliably. In addition, according to this embodiment, the same effects as those of the first embodiment (i.e., for example, the effect of improving wiring workability and maintainability, and the effect of preventing water damage) are also achieved, but since this has been described in detail in the first embodiment, the description here is omitted.

[0059] (Embodiment 3) Next, a third embodiment will be described. In this embodiment, a fire detector is provided in a fire hydrant section.

[0060] (composition) The configuration of the fire hydrant device of this embodiment will be described below. Fig. 9 is a front view of the fire hydrant device, and Fig. 10 is a front view of the fire hydrant device with the fire hydrant door and the maintenance door open.

[0061] As shown in FIG. 1, the fire hydrant device 300 is installed in a tunnel in the same manner as the fire hydrant device 100 of embodiment 1, and as shown in FIG. 9, for example, includes a housing 3, a fire detector 81C, a red indicator light 82C, a manual transmitter 83C, and a response lamp 84C.

[0062] (Configuration - Chassis) 9, the housing 3 includes a fire extinguisher storage section 31, a fire hydrant section 32, and panel sections 3A1 and 3A2. The front (+X direction) faces of the panel sections 3A1 and 3A2, for example, facing the inside of a tunnel, which is the monitored area, and is parallel to the YZ plane, and corresponds to the above-mentioned "panel surface." In particular, the front (+X direction) face of the panel section 3A1 corresponds to the "first panel surface," and the front (+X direction) face of the panel section 3A2 corresponds to the "second panel surface."

[0063] (Configuration - Housing - Fire hydrant section) As shown in FIG. 10, the fire hydrant unit 32 includes a hose storage space 33 and a piping storage space .

[0064] (Configuration - Fire detector) The fire detector 81C in Figure 9 is provided, for example, near a red indicator light 82C, a manual transmitter 83C, and a response lamp 84C, and is also provided on the panel portion 3A1, and is also provided on the other side in the horizontal direction (-Y direction) of the storage section center 330 in Figure 10 in the housing 3.

[0065] (Consists of a red indicator light, a manual transmitter, and an answer lamp) The red indicator light 82C, manual transmitter 83C, and response lamp 84C in Fig. 9 are notification devices, and are provided, for example, on the panel unit 3A2, and are provided on the other side in the horizontal direction (-Y direction) of the storage unit center 330 in Fig. 10 in the housing 3. The red indicator light 82C is provided, for example, at approximately the same height as the fire detector 81C in the vertical direction (Z-axis direction). Here, the portion other than the fire hydrant unit 32, that is, the unit including the fire extinguisher storage unit 31 on the -Y direction side of the fire hydrant unit 32 and the panel unit 3A2 on which the notification device is provided, applies a general configuration of a conventional fire hydrant device not provided with a fire detector.

[0066] (Effects of the embodiment) Thus, according to this embodiment, since the fire detector 81C is provided in the fire hydrant section 32, the unit including the fire extinguisher storage section and the panel section provided with the reporting device other than the fire hydrant section 32 can have a common configuration with the conventional unit, improving production efficiency. Also, according to this embodiment, the same effects as those of the first embodiment (that is, for example, the effect of improving wiring workability and maintainability, and the effect of preventing water damage) are achieved, but since this has been described in detail in the first embodiment, a description thereof will be omitted here.

[0067] (Embodiment 4) Next, a fourth embodiment will be described. In this embodiment, the fire detector is placed on the upper side of the panel surface, and the light entrance part of the fire detector and at least a part of the part other than the light entrance part are provided on the monitoring area side of the panel surface.

[0068] (composition) The configuration of the fire hydrant device of this embodiment will be described. Figures 11 and 12 are diagrams showing the installation state of the fire hydrant device, Figure 13 is a front view of the fire hydrant device, Figure 14 is a front view of the fire hydrant device with the fire hydrant door and the maintenance door open, and Figure 15 is a side view of the fire hydrant device with the fire hydrant door and the maintenance door open. Note that Figure 15 shows a state in which a part of the side of the fire hydrant device 400 is broken so that the inside can be seen.

[0069] The fire hydrant device 400 may be installed in a storage section 94 in a tunnel wall 93, as shown in FIG. 11, similar to the fire hydrant devices of the other embodiments, or may be embedded in a guard passage 92, as shown in FIG. 12.

[0070] As shown in FIG. 13, the fire hydrant device 400 includes, for example, a housing 4, a mounting box 700, a fire detector 81D, a red indicator light 82D, a manual transmitter 83D, and a response lamp 84D.

[0071] (Configuration - Chassis) The housing 4 includes a fire extinguisher storage section 41, a fire hydrant section 42, and a panel section 4A2, as shown in Fig. 13, for example. The front side (+X direction) surface of the panel section 4A2 corresponds to the "panel surface", and in particular, corresponds to the "second panel surface." In Fig. 13 and Figs. 14 and 15 described below, the panel section 4A1 (first panel surface) and the panel section 4A2 (second panel surface) are parallel to the Z axis.

[0072] (Configuration - Housing - Fire hydrant section) As shown in FIG. 14, the fire hydrant unit 42 includes a hose storage space 43 and a piping storage space 44.

[0073] (Configuration - Mounting box) The mounting box 700 is a member for mounting the fire detector 81D to the housing 4. The specific configuration of this mounting box 700 is arbitrary, but for example, it is for accommodating the light-transmitting portion 812A of the fire detector 81D and a part other than the peripheral portion of the light-transmitting portion 812A (for example, the main body 811 in FIG. 6) and mounting the fire detector 81D to the housing 4. In addition, the mounting box 700 includes, for example, a panel portion 4A1.

[0074] (Configuration - Mounting box - Panel section) 15, the panel section 4A1 is a portion provided on the front side (+X direction) of the mounting box 700, and is a portion provided further forward (+X direction) than the front side (+X direction) surface of the housing 4. The front side (+X direction) surface of the panel section 4A1 corresponds to the "panel surface", and in particular corresponds to the "first panel surface".

[0075] (Configuration - Fire detector) 13 is provided near the red indicator lamp 82D, the manual transmitter 83D, and the response lamp 84D, for example, and is provided on the other side (-Y direction) in the lateral direction of the storage section center 430 in the housing 4 in FIG. 14. The fire detector 81D is provided, for example, on the upper side (+Z direction) of the panel section 4A2 of the housing 4, and the fire detector 81D is provided forward (+X direction) of the front side (+X direction) of the front surface of the panel section 4A2 of the housing 4 in FIG. 15.

[0076] A specific method for providing this fire detector 81D is arbitrary, but for example, as shown in Fig. 14 and Fig. 15, a method of mounting the fire detector 81D to the housing 4 using a mounting box 700 may be used. More specifically, for example, the fire detector 81D may be mounted by fixing the fire detector 81D to the panel part 4A1 of the mounting box 700 from inside the mounting box 700 using a fixing means such as a bolt, with a part of the fire detector 81D exposed from an opening of the mounting box 700, and fixing the mounting box 700 to the upper part (+Z direction) of the housing 4 using a fixing means such as a mounting bracket 701. When mounted in this manner, the fire detector 81D is placed on the upper side (+Z direction) of the panel part 4A2 (i.e., placed on the upper part of the housing 4).

[0077] The configuration of the mounting bracket 701 may be changed arbitrarily. For example, the configuration of the mounting bracket 701 may be changed so that the mounting box 700 is attached facing diagonally downward in the side view of FIG. 15 (that is, so that the line perpendicular to the panel section 4A1 is inclined downward (-Z direction) in the forward (+X direction), that is, so that the angle α (90° in the figure) is smaller than 90° in the side view of FIG. 15). Alternatively, the configuration of the mounting bracket 701 may be changed so that the mounting box 700 can be rotated around a rotation axis parallel to the Y axis at the lower end (-Z direction) of the mounting box 700 relative to the housing 4 and fixed at a predetermined angle in the side view of FIG. 15. By configuring in this way, when the fire hydrant device 400 is installed in the storage section 94 shown in FIG. 11, it is possible to prevent the mounting box 700 from interfering with the curvature part of the tunnel wall surface 93 (a part of the upper part (+Z direction) of the storage section 94).

[0078] Although it has been explained here that the configuration of mounting bracket 701 may be changed so that angle α is smaller than 90° in the side view of Fig. 15, any angle may be selected as long as mounting box 700 does not interfere with the curved portion of tunnel wall surface 93. Also, it is not prevented from tilting angle α so that it is larger than 90° depending on various circumstances of the installation environment.

[0079] (Consists of a red indicator light, a manual transmitter, and an answer lamp) 13 are notification devices, and are provided, for example, on the other side in the horizontal direction (-Y direction) of the storage section center 430 in the housing 4 in Fig. 14. Also, at least the red indicator light 82D (the entire notification device in the form of Fig. 13) among the notification devices is provided, for example, at a position at a different height from the fire detector 81D in the vertical direction (Z-axis direction), and at least a part (the entirety in the form of Fig. 13) of the display portion of the exposed part of the red indicator light 82D is arranged so as not to overlap with the protruding part of the fire detector 81D in the height direction.

[0080] (Effects of the embodiment) Thus, according to this embodiment, since the fire detector 81D is mounted on the upper side of the panel section 4A2, for example, the fire detector 81D can be installed at a relatively high position, and therefore it is possible to improve or expand the fire detection accuracy or detection range. That is, for example, it is possible to suppress a decrease in fire detection accuracy caused by the fire detector 81D receiving light from the headlights of a vehicle on the lower side (road surface 91 side) of the monitoring area from a short distance, to reduce the occurrence of a blind spot caused by a vehicle stopped near the front of the fire hydrant device 400, and further, to prevent a decrease in fire detection sensitivity (narrowing of the detection range) on the upper side of the monitoring area caused by installing the fire detector 81D at a low position. In addition, at least a part of the light-transmitting portion 812A of the fire detector 81D and the portion other than the light-transmitting portion 812A of the fire detector 81D is provided so as to be located closer to the monitoring area side (+X direction) than the panel portion 4A1, so that, for example, the effect of the curvature of the tunnel wall surface 93 can be avoided and the fire detector 81D can be provided at a position that does not interfere with the wall surface, as shown in FIG. 11. In addition, for example, when the fire hydrant device 400 is embedded and installed in the hollowed-out portion of the watchman passage 92 as shown in FIG. 12, the fire detector 81D can be provided at a position that does not interfere with the passage of the watchman passage 92. In addition, according to this embodiment, the same effects as those of the first embodiment (that is, for example, the effect of improving wiring workability and maintainability, and the effect of preventing water damage) are also achieved, but since they have been described in detail in the first embodiment, the description here will be omitted.

[0081] (Embodiment 5) Next, a description will be given of embodiment 5. In this embodiment, a fire detector and a notification device are provided on one side with respect to the lateral center of the hose housing part.

[0082] (composition) The configuration of the fire hydrant device of this embodiment will be described below. Fig. 16 is a front view of the fire hydrant device with the fire hydrant door and the maintenance door open.

[0083] As shown in FIG. 1, the fire hydrant device 500 is installed in a tunnel in the same manner as the fire hydrant device 100 of embodiment 1, and as shown in FIG. 16, for example, includes a housing 5, a fire detector 81E, a red indicator light 82E, a manual transmitter 83E, and a response lamp 84E.

[0084] (Configuration - Chassis) The housing 5 includes, for example, a fire extinguisher storage section 51, a fire hydrant section 52, and panel sections 5A1 and 5A2. The front (+X direction) faces of the panel sections 5A1 and 5A2, for example, facing the inside of a tunnel, which is the monitored area, and is parallel to the YZ plane, and corresponds to the above-mentioned "panel surface." In particular, the front (+X direction) face of the panel section 5A1 corresponds to the "first panel surface," and the front (+X direction) face of the panel section 5A2 corresponds to the "second panel surface."

[0085] (Configuration - Housing - Fire hydrant section) The fire hydrant section 52 includes a hose storage space 53 and a piping storage space 54 .

[0086] (Configuration - Fire detector) The fire detector 81E is provided, for example, near the red indicator light 82E, the manual transmitter 83E, and the response lamp 84E, and is provided on the panel unit 5A1, and is provided on one side in the horizontal direction (+Y direction) of the storage unit center 530 in the housing 5. The fire detector 81E is provided, for example, above the internal piping 141 in the vertical direction (Z-axis direction) (+Z direction).

[0087] (Consists of a red indicator light, a manual transmitter, and an answer lamp) The red indicator light 82E, the manual transmitter 83E, and the response lamp 84E are notification devices, and are provided, for example, on the panel unit 5A2, on one side in the horizontal direction (-Y direction) of the storage unit center 530 in the housing 5. The red indicator light 82E is provided, for example, at approximately the same height as the fire detector 81E in the vertical direction (Z-axis direction).

[0088] (Effects of the embodiment) Thus, according to this embodiment, the internal piping 141 and the fire hydrant connection port 142 are provided on one horizontal side (+Y direction) based on the storage center 530 of the hose storage space 53, and the fire detector 81E, the red indicator light 82E, the manual transmitter 83E, and the response lamp 84E are provided on one horizontal side (-Y direction) based on the storage center 530 of the hose storage space 53. Therefore, for example, maintenance of the internal piping 141, the fire hydrant connection port 142, the fire detector 81E, the red indicator light 82E, the manual transmitter 83E, and the response lamp 84E can be performed on only one side (+Y direction) of the fire hydrant device 500, thereby improving maintainability. In addition, if a pump start switch 146 (a start switch for starting water discharge from the fire brigade water faucet), which is an electrical component provided near the supply means, is provided, the pump start switch 146 will also be located near the fire detector 81E and the reporting device, making it easier to perform electrical maintenance on the fire detector 81E and the reporting device.

[0089] [Modifications to the embodiment] Although the embodiments of the present invention have been described above, the specific configurations and means of the present invention can be modified and improved as desired within the scope of the technical ideas of the inventions described in the claims. Such modifications will be described below.

[0090] (About the problem to be solved and the effects of the invention) First, the problems that the invention aims to solve and the effects of the invention are not limited to those described above, and may vary depending on the implementation environment of the invention and the details of the configuration, and may solve only some of the problems described above or achieve only some of the effects described above.

[0091] (Regarding decentralization and integration) In addition, the above-mentioned configuration is a functional concept, and does not necessarily have to be physically configured as shown in the drawings. In other words, the specific form of distribution or integration of each part is not limited to that shown in the drawings, and all or part of it can be functionally or physically distributed or integrated in any unit.

[0092] (Effects of each embodiment) In addition, the above-mentioned embodiments also have the following effects. For example, in the fire hydrant device 100 of the first embodiment, when a known terminal board or terminal block is provided on the rear side (-X direction) of the fire detector 81A inside the housing 1, the fire detector 81A is provided on the front side (+X direction) of the terminal board or terminal block, so that it is possible to effectively utilize the dead space around the terminal board or terminal block. In addition, in the fire hydrant device 200 of the second embodiment, it is possible to store a relatively long fire extinguisher in the fire extinguisher storage section 21. In addition, in the fire hydrant devices 300 and 400 of the third and fourth embodiments, it is possible to provide the fire hydrant devices 300 and 400 of the present application with relatively few design changes to conventional fire hydrant devices (for example, fire hydrant devices not provided with a fire detector). Furthermore, in the fire hydrant device 400 of the fourth embodiment, when the fire hydrant device 400 is provided in the hollowed-out portion of the monitor passage 92 in Fig. 12, it becomes possible to provide the fire detector 81D at a position that avoids the monitor passage 92. Furthermore, in the fire hydrant device 500 of the fifth embodiment, since the supply means and each target device can be collected on one side (+Y direction) of the housing 5, electrical maintenance and maintenance related to the water supply can be performed on that side, and it becomes possible to improve maintainability.

[0093] (Relationship between effective visual field and components of fire hydrant equipment) In addition, in the above embodiment 1, it has been described that the red indicator light 82A does not enter the effective field of view of the fire detector 81A, but this is not limited thereto. For example, the fire hydrant device 100 may be configured so that some of the components other than the fire detector 81A (e.g., panel sections 1A1, 1A2, etc.), or all of the components, do not enter the effective field of view of the fire detector 81A.

[0094] (Regarding the protruding amount of the red indicator light) In the above-mentioned embodiment 1, the red indicator light 82A in Fig. 1 is described as protruding to such an extent that it does not enter the effective visual field space of the fire detector 81A, but this is not limited thereto. For example, the red indicator light 82A may be provided on the same plane as the panel part 1A2 of the housing 1 without protruding, or may be provided recessed from the panel part 1A2, or may be protruding to such an extent that it enters the effective visual field space of the fire detector 81A from the viewpoint of improving the visibility of the red indicator light 82A. In this case, for example, the protruding amount of the red indicator light 82A to the front side (+X direction) may be configured to be larger than the protruding amount of the fire detector 81A to the front side (+X direction).

[0095] (Indicator light color) In addition, in the above embodiments, the indicator light has been described as a red indicator light, but the color of the indicator light may be changed as desired based on, for example, laws, regulations, or required specifications. For example, the light emission color of the indicator light may be changed to green, and the indicator light may be configured as a green indicator light instead of a red indicator light, or the indicator light may be configured to emit light of another color.

[0096] (Regarding the horizontal center of the hose storage area) In the above embodiment, the "horizontal center of the hose storage section" is described as being approximately the center of the width from the partition walls 13A to 13B in the horizontal direction (Y-axis direction) in FIG. 3. However, the "partition walls" 13A and 13B do not necessarily need to be physical walls, and may include other appropriate partition structures or virtual partition boundaries. The "horizontal center of the hose storage section" may be interpreted as follows. Specifically, when the hose storage section is not partitioned by a partition wall, the "horizontal center of the hose storage section" may be interpreted as being approximately the center of the distance between both ends in the Y-axis direction of the wound part of the water discharge hose that is stored in a wound state inside the fire hydrant device. More specifically, the "horizontal center of the hose storage section" may be interpreted as being an imaginary line along the vertical direction (Z-axis direction) that passes through the middle between the end on one side (+Y direction) and the end on the other side (-Y direction) in the horizontal direction (Y-axis direction) of the wound part of the water discharge hose. Also, an imaginary line along the vertical direction (Z-axis direction) that passes through approximately the center (winding center) of the wound part of the water discharge hose may be interpreted as the "horizontal center of the hose storage part." Also, it is assumed that the center of the hose storage space is defined when the fire hydrant device is designed, taking into consideration the fit of the water discharge hose, and the center of this defined hose storage space may be interpreted as the "horizontal center of the hose storage part."

[0097] (Features) Furthermore, the configurations of the above-described embodiments and the features of the modified examples may be combined in any manner.

[0098] (Additional Note) The fire hydrant device of Appendix 1 is a fire hydrant device installed in a tunnel, and comprises a fire detector that detects a fire by receiving light from a monitored area inside the tunnel via a light incident part, a reporting device, and a panel surface facing the monitored area, wherein the fire detector is arranged with the light incident part protruding from the panel surface toward the monitored area, and the reporting device is arranged with at least a part of the reporting device exposed from the panel surface toward the monitored area, and further wherein the fire detector and the reporting device are provided in the vicinity of each other.

[0099] The fire hydrant device of Appendix 2 is the fire hydrant device described in Appendix 1, further comprising a supply means for supplying fire water from outside the fire hydrant device, and a hose storage section for storing a fire hose for discharging the fire water supplied to the supply means, wherein the supply means is provided on one lateral side based on the lateral center of the hose storage section when the fire hydrant device is in an installed state, and the fire detector and the reporting device are provided on the other lateral side based on the lateral center of the hose storage section.

[0100] The fire hydrant device of Appendix 3 is the fire hydrant device described in Appendix 1, further comprising a supply means for supplying fire water from outside the fire hydrant device, and a hose storage section for storing a fire hose for discharging the fire water supplied to the supply means, wherein the supply means is provided on one lateral side with respect to the lateral center of the hose storage section when the fire hydrant device is in an installed state, and the fire detector and the reporting device are provided on one lateral side with respect to the lateral center of the hose storage section.

[0101] The fire hydrant device of Supplementary Note 4 is a fire hydrant device described in any one of Supplementary Notes 1 to 3, wherein the panel surface comprises a first panel surface on which the fire detector is arranged and a second panel surface on which the reporting device is arranged, the fire detector is placed on the upper side of the second panel surface, and the light entrance portion of the fire detector and at least a part of the portion other than the light entrance portion are arranged to be located at least closer to the monitoring area than the first panel surface.

[0102] A fire hydrant device of Supplementary Note 5 is a fire hydrant device described in any one of Supplementary Notes 1 to 4, wherein the fire detector and the reporting device are provided at different heights in the vertical direction when the fire hydrant device is installed.

[0103] A fire hydrant device of Supplementary Note 6 is a fire hydrant device according to any one of Supplementary Notes 1 to 5, in which the outer shape of a component of the fire hydrant device does not fall within an effective visual field space for the light entrance portion of the fire detector.

[0104] (Effect of supplementary notes) According to the fire hydrant device described in Appendix 1, the fire detector and the notification device are installed in close proximity to each other, which, for example, simplifies the routing of the wiring for the fire detector and the notification device, simplifies the wiring work and improves the efficiency of the wiring work, and makes it possible to efficiently perform work such as checking the wiring of the fire detector and the notification device.

[0105] According to the fire hydrant device described in Appendix 2, the supply means is provided on one horizontal side with respect to the horizontal center of the hose storage section, and the fire detector and reporting device are provided on the other horizontal side with respect to the horizontal center of the hose storage section. As a result, for example, the fire detector and reporting device can be separated from the supply means, making it possible to prevent leakage current on the fire detector and reporting device side due to water droplets around the supply means, etc.

[0106] According to the fire hydrant device described in Supplementary Note 3, the supply means is provided on one side of the lateral direction based on the lateral center of the hose storage section, and the fire detector and notification device are provided on one side of the lateral direction based on the lateral center of the hose storage section, so that, for example, maintenance of the supply means and the fire detector and notification device can be performed on only one side of the fire hydrant device, improving maintainability. Also, in the case of a pump start switch (a start switch for starting water discharge from a fire brigade water hydrant) that is an electrical component provided near the supply means, the pump start switch is also located near the fire detector and notification device, so that electrical maintenance can be easily performed together with the fire detector and notification device.

[0107] According to the fire hydrant device described in Supplementary Note 4, since the fire detector is mounted on the upper side of the second panel surface, for example, the fire detector can be installed at a relatively high position, and it is possible to improve or expand the fire detection accuracy or detection range. That is, it is possible to suppress the decrease in fire detection accuracy caused by the fire detector receiving light from the headlights of vehicles on the lower side (road surface side) of the monitoring area from a short distance, to reduce the occurrence of blind spots caused by vehicles stopped near the front of the fire hydrant device, and to prevent the decrease in fire detection sensitivity (reduction of the detection range) on the upper side of the monitoring area caused by installing the fire detector at a low position. In addition, since at least a part of the light entrance part and the part other than the light entrance part of the fire detector are arranged to be located closer to the monitoring area side than the panel surface, for example, it is possible to install the fire detector at a position that does not interfere with the wall surface by avoiding the influence of the curvature of the tunnel side wall surface. In addition, for example, when the fire hydrant device is installed embedded in the hollowed-out part of the guard passage, it is possible to install the fire detector at a position that does not interfere with the passage of the guard passage.

[0108] According to the fire hydrant device described in Supplementary Note 5, the fire detector and the notification device are provided at different heights in the vertical direction when the fire hydrant device is installed, so that it is possible to reliably detect a fire that occurs horizontally of the fire detector. It is also possible to improve the visibility of the display means (e.g., a red indicator light or a response lamp), which is an example of a notification device, from the side of the fire hydrant device. Similarly, it is possible to prevent the fire detector from obstructing the user's view of the position of the manual transmitter from the side when the user needs to operate it.

[0109] According to the fire hydrant device described in Appendix 6, the outer shape of the components of the fire hydrant device does not enter the effective visual field space for the light entrance part of the fire detector, making it possible to reliably detect a fire using a fire detector, for example.
