Fire extinguishing equipment storage device

Abstract

To enable proper operation management of an emergency facility that requires a fire report with fire confirmation before using a hydrant and a fire extinguisher.SOLUTION: When a road user performs a fire report by operating a transmitter 24, fixation which disables operation of a hydrant door 15 and a fire extinguisher door 18 is released with operation of a hydrant door electromagnetic solenoid 36 and a fire extinguisher door electromagnetic solenoid 44, and fire fighting can be performed by using a hydrant instrument and the fire extinguisher. Even when the road user tries to open the hydrant door 15 and the fire extinguisher door 18 without operating the transmitter 24, the doors cannot be opened due to fixation. In this case, touch operation is detected by a hydrant door touch switch 38 when, for example, the road user puts the hand on a door handle 1510 of the hydrant door 15, a voice message is output from a speaker part 54 as operation guide that urges the fire confirmation and fire report, and a transmitter guide display part 52 blinks.SELECTED DRAWING: Figure 2

Description

Technical Field

[0001] The present invention relates to a fire hydrant device installed in a tunnel for storing a fire hose and a fire extinguisher, etc., and a fire equipment storage device such as a fire extinguisher box installed in a tunnel for storing a fire extinguisher.

Background Art

[0002] Conventionally, in tunnels such as highways and motorways, a fire hydrant device is installed as an emergency facility in the tunnel. The fire hydrant device stores a fire hose with a nozzle attached to its tip and valves including a fire hydrant valve in a fire hydrant storage section of a housing equipped with a fire hydrant door, and also stores, for example, two fire extinguishers in a fire extinguisher storage section equipped with a fire extinguisher door. Also, the fire hydrant device is generally installed by cutting out the tunnel wall surface at intervals of, for example, 50 meters in the longitudinal direction of the tunnel and embedding it.

[0003] In addition, an emergency reporting device is provided in the fire hydrant device. The emergency reporting device is provided with a red indicator light, a transmitter, a response lamp, and a telephone jack on an emergency reporting door (electrical equipment door) arranged between the fire hydrant storage section and the fire extinguisher storage section.

[0004] The red indicator light is always on so that the installation location of the fire hydrant device can be confirmed from a distance. When a fire breaks out and the transmitter is pressed to turn on the push button switch, a fire alarm signal is transmitted to a disaster prevention receiving board installed in an electrical room or the like, and a fire alarm is output. The disaster prevention receiving board that has output the fire alarm transmits a response signal to the emergency reporting device, causing the red indicator light to blink and the response lamp to light, enabling confirmation that the fire alarm signal has been received on the disaster prevention receiving board side (Patent Document 1).

[0005] Furthermore, since road users are generally unfamiliar with operating fire hydrant systems, when a road user opens the fire hydrant door, they can see instructions on how to operate the fire hydrant system, illustrated with pictures and text. However, in urgent situations such as a fire, it may be difficult to operate the fire hydrant system while reading the instructions. Therefore, fire hydrant systems equipped with a function to guide users on how to operate the fire hydrant system through displays and voice prompts have been proposed (Patent Documents 2, 3). [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 2002-102380 [Patent Document 2] Japanese Patent Publication No. 2003-310785 [Patent Document 3] Japanese Patent Publication No. 2019-118423 [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] By the way, if a vehicle fire occurs inside a tunnel due to an accident or other reason, road users will operate a transmitter to report the fire, and then use a fire hydrant or fire extinguisher to put out the fire.

[0008] However, in urgent situations such as a fire, it is conceivable that some road users may use fire hydrants or fire extinguishers to extinguish the fire without operating the transmitter to report the fire. If the transmitter is not operated, the fire alarm will not be issued by the disaster prevention receiving panel, and the road administrator will not be aware of the fire. Furthermore, the disaster prevention receiving panel is designed to activate other emergency equipment in coordination with the transmission when it receives both a fire signal from fire detectors installed at 25-meter or 50-meter intervals along the length of the tunnel and a fire alarm signal from the transmitter. However, if the transmitter is not operated, the coordination of other emergency equipment will not occur, which could seriously hinder operational management in the event of a fire.

[0009] Furthermore, the operating instructions provided by conventional fire hydrant systems only guide users through the procedure of opening the fire hydrant door, removing the fire hose nozzle, and opening the fire hydrant valve to discharge water. These instructions do not mention the operation of a fire alarm by using a transmitter prior to operating the fire hydrant. As a result, some road users may operate the fire hydrant system and engage in firefighting activities without first using a transmitter to report a fire, which still presents a problem.

[0010] This problem also applies to fire extinguisher boxes equipped with emergency alarm systems, which are installed as emergency equipment in lower-ranked tunnels, categorized by factors such as traffic volume and tunnel length.

[0011] The present invention aims to provide a fire hydrant system and a fire extinguisher box that enable proper operation and management of emergency equipment by requiring fire notification via the operation of a transmitter before using fire hydrants or fire extinguishers. [Means for solving the problem]

[0012] (Fire extinguishing equipment storage device 1) The present invention relates to a fire extinguishing equipment storage device installed in a tunnel, in which predetermined fire extinguishing equipment is stored inside a housing having a storage door, and an emergency notification device including a transmitter is provided at a predetermined position in the housing, The system is characterized by having a control unit that disables the opening of the storage door under normal conditions, and enables the opening of the storage door when operation of the transmitter is detected.

[0013] (Guidance on maintaining the door closed and operating the transmitter) If the control unit detects an attempt to open the storage door without detecting any operation of the transmitter, it will maintain the inability to open the storage door and output an operation guide prompting the user to operate the transmitter.

[0014] (Fire extinguishing equipment storage device 2) The present invention relates to a fire extinguishing equipment storage device installed in a tunnel, in which predetermined fire extinguishing equipment is stored inside a housing having a storage door, and an emergency notification device including a transmitter is provided at a predetermined position in the housing, A door locking mechanism that locks the storage door in an unopenable position when the drive unit is not operating, and releases the lock on the storage door when the drive unit is operating, A control unit that, when operation of the transmitter is detected, releases the lock on the storage door using the door locking mechanism, allowing it to be opened, It is characterized by having the following features.

[0015] (Instructions for maintaining door lock and operating the transmitter) The storage door is equipped with a door contact detector that detects human contact with the door handle. If the control unit detects human contact with the door handle of the storage door via the door contact detector without detecting operation of the transmitter, it maintains the storage door's locking mechanism and outputs voice and / or display guidance prompting the user to operate the transmitter.

[0016] (Door fixing drive unit using electromagnetic drive unit) The drive unit of the door fixing mechanism is an electromagnetic drive unit. The electromagnetic drive unit releases the lock on the storage door by moving the plunger, which constitutes the movable electrode, using the electromagnetic force of the fixed electrode generated by the energization of the coil.

[0017] (Power cut off after the locking mechanism is released) The storage door is equipped with a door open / close detector that detects when the storage door is opened or closed. After the control unit releases the fixing of the storage door by energizing the electromagnetic drive unit, if the opening of the storage door is detected by the door opening / closing detector, the control unit stops the energization of the electromagnetic drive unit of the door fixing mechanism.

[0018] (Manual release of door fixing) The door fixing mechanism includes a manual fixing release unit that releases the fixing of the storage door when the plunger is moved manually.

[0019] (Fire hydrant device and fire extinguisher box) The fire equipment storage device is a fire hydrant storage unit of a fire hydrant device in which predetermined fire hydrant equipment including a fire hose is stored in a housing having a fire hydrant door, a fire extinguisher storage unit of a fire hydrant device in which a fire extinguisher is stored in a housing having a fire extinguisher door, or a fire extinguisher box in which a fire extinguisher is stored in a housing having a fire extinguisher door.

Advantages of the invention

[0020] (Advantages of the fire equipment storage device 1) The present invention is a fire equipment storage device installed in a tunnel, in which predetermined fire equipment is stored inside a housing having a storage door, and an emergency reporting device including a transmitter is provided at a predetermined position of the housing. The control unit is provided to disable the opening operation of the storage door in the normal state and enable the opening operation of the storage door when the operation of the transmitter is detected. Therefore, since road users cannot open the storage door unless they operate the transmitter to report a fire, the operation of the transmitter is essential when using the fire equipment. By ensuring that road users operate the transmitter, a fire alarm is output from the disaster prevention receiving board, and the road manager can surely know the occurrence of a fire and take prompt and appropriate measures. In addition, it is possible to surely perform coordinated operations of other emergency facilities corresponding to the fire alarm, such as prohibiting the entry into the tunnel by an electric display installed at the tunnel entrance.

[0021] (Effect of maintaining the inability to open the door and guiding the operation of the transmitter) Furthermore, the control unit is designed to maintain the inability to open the storage door and output operational guidance prompting the user to operate the transmitter if an attempt is made to open the storage door without the transmitter being operated. As a result, even if a road user tries to open the storage door to use the fire extinguishing equipment without operating the transmitter, it will not open. However, the operational guidance prompting the user to operate the transmitter will alert the road user to the need to operate the transmitter, allowing them to open the door. This enables them to report a fire and use the fire extinguishing equipment appropriately and quickly without being confused by the inability to open the storage door.

[0022] (Effects of Fire Extinguishing Equipment Storage Device 2) The present invention relates to a fire extinguishing equipment storage device installed in a tunnel, in which predetermined fire extinguishing equipment is stored inside a housing having a storage door, and an emergency notification device including a transmitter is provided at a predetermined position in the housing. The device includes a door fixing mechanism that fixes the storage door so that it cannot be opened when the drive unit is not operating, and releases the fixing of the storage door when the drive unit is operating, and a control unit that, when operation of the transmitter is detected, releases the fixing of the storage door using the door fixing mechanism, allowing it to be opened. Therefore, as with the fire extinguishing equipment storage device 1 described above, operation of the transmitter is essential to release the fixing of the storage door by the door fixing mechanism and use the fire extinguishing equipment. As a result, when the transmitter is reliably operated by a road user, a fire alarm is output from the disaster prevention receiver panel, allowing road administrators to reliably know about the occurrence of a fire and take quick and appropriate action. Furthermore, it is possible to reliably perform coordinated operation of other emergency equipment in response to the fire alarm, such as displaying a prohibition on tunnel entry on an electronic display installed at the tunnel entrance.

[0023] (Effect of maintaining door lock and providing guidance on transmitter operation) Furthermore, the storage door is equipped with a door contact detector that detects human contact with the door handle. The control unit maintains the door's locking mechanism when the door contact detector detects human contact with the door handle without detecting any operation of the transmitter, and outputs voice and / or display guidance prompting the user to operate the transmitter. As described above, in the case of the fire extinguishing equipment storage device 1, the door will not open even if a road user tries to open it to use the fire extinguishing equipment without operating the transmitter. However, the voice and display guidance prompting the user to operate the transmitter allows them to know that they should operate the transmitter and to open the door, enabling them to appropriately and quickly report a fire and subsequently use the fire extinguishing equipment by opening the storage door without being confused by the door's locking mechanism.

[0024] Furthermore, when a road user attempts to open the storage door and places their hand on the door handle, the door contact detector detects the hand's contact with the handle and outputs an operation guide, which prompts the user to operate the transmitter at the appropriate time when attempting to open the storage door. In cases where firefighting is the top priority, the system may be configured so that when the door contact detector detects the hand's contact with the door handle, the storage door is made open and the transmitter operation guide is output.

[0025] (Effects of a door fixing drive unit using an electromagnetic drive unit) Furthermore, the door locking mechanism's drive unit is an electromagnetic drive unit. The electromagnetic drive unit releases the locking of the storage door by moving the plunger, which constitutes the movable electrode, using the electromagnetic force of the fixed electrode generated by energizing the coil. Therefore, as the electromagnetic drive unit, it is possible to use, for example, a pull-type (retraction-type) electromagnetic solenoid that retracts the plunger when energized. Since pull-type electromagnetic solenoids are commonly used as general-purpose products, they offer high reliability, a wide variety of types, and can reduce costs.

[0026] (Effect of cutting off power after the door is released) Furthermore, the fire extinguishing equipment storage device is equipped with a door opening / closing detector that detects the opening and closing of the storage door. The control unit releases the storage door by energizing the electromagnetic drive unit, and then, when the door opening / closing detector detects that the storage door is open, it stops the power supply to the electromagnetic drive unit of the door fixing mechanism. Therefore, from the time a road user puts their hand into the door handle of the storage door until the storage door opens, the electromagnetic solenoid, which is the electromagnetic drive unit, is energized and released, and then the power supply is stopped, thus shortening the energizing time and enabling power saving.

[0027] (Effect of manually releasing the door lock) Furthermore, the door locking mechanism includes a manual lock release unit that releases the lock on the storage door when the plunger is moved manually. Therefore, even if the electromagnetic solenoid, which is provided as the electromagnetic drive unit, malfunctions and the lock cannot be released, the storage door can be released and opened by manually operating the manual lock release unit, ensuring a high level of fail-safe capability.

[0028] (Effects of fire hydrant systems and fire extinguisher boxes) Furthermore, since the fire extinguishing equipment storage device is a fire hydrant storage section of a fire hydrant system in which predetermined fire hydrant equipment, including a fire hose, is stored in a housing with a fire hydrant door, a fire extinguisher storage section of a fire hydrant system in which a fire extinguisher is stored in a housing with a fire extinguisher door, or a fire extinguisher box in which a fire extinguisher is stored in a housing with a fire extinguisher door, the aforementioned effects can be obtained in each case.

[0030] The following describes in detail an embodiment of the fire extinguishing equipment storage device according to the present invention, based on the drawings. However, the present invention is not limited to the following embodiments.

[0031] [Basic Concepts of the Embodiment] First, the basic concept of the embodiment will be explained. The embodiment is, in general terms, related to a fire extinguishing equipment storage device.

[0032] Here, "fire extinguishing equipment storage device" refers to a type of emergency equipment installed in tunnels of expressways and motorways that are designated as fire-fighting areas. It is installed in the fire-fighting area, has a housing with a storage door, and contains or stores designated fire extinguishing equipment. An emergency notification device, including a transmitter, is also placed in a designated location within the housing.

[0033] Furthermore, a "transmitter" is equipped with a push-button switch, and when a road user operates the push-button switch, a fire alarm signal is transmitted to a disaster prevention receiving panel installed in the tunnel's electrical room or similar location, causing a fire alarm to be issued.

[0034] The "fire extinguishing equipment storage device" of this embodiment is equipped with a control unit that normally prevents the storage door from being opened, but enables the storage door to be opened when the operation of the transmitter is detected.

[0035] Here, "making it impossible to open the storage door" means that road users need to open the storage door when using the fire extinguishing equipment storage device, but at the very least, they are prevented from opening the storage door. Furthermore, "making it possible to open the storage door" means that the storage door, which has been made impossible to open, is made operable.

[0036] The structure for implementing the function of preventing the storage door from being opened and enabling it to be opened is arbitrary, but for example, it includes a door fixing mechanism that fixes the storage door in an unopenable state when the drive unit is not operating and releases the fixing of the storage door when the drive unit is operating, and a control unit that releases the fixing of the storage door by operating the door fixing mechanism when operation of the transmitter is detected, allowing it to be opened. Note that "fixing" includes concepts such as lock, latch, locking, restraint, or stop.

[0037] Furthermore, the mechanism, structure, and type of the "door fixing mechanism drive unit" are arbitrary, but for example, it could be an electromagnetic drive unit. Here, the "electromagnetic drive unit" is a system that releases the lock on the storage door by moving a plunger (push rod) that constitutes the movable electrode unit using the electromagnetic force of the fixed electrode unit generated by energizing the coil. This concept includes, for example, a pull-type (retraction-type) "electromagnetic solenoid" that retracts the plunger when energized. Pull-type electromagnetic solenoids are readily available, easy to obtain, highly reliable, and inexpensive. Note that the "plunger (push rod)" is a rod-shaped member and is a concept that includes shaft members, pin members, rod members, etc.

[0038] Therefore, unless a road user operates the transmitter to report a fire, the storage door will be locked and cannot be opened. This means that operating the transmitter before using fire extinguishing equipment is essential. When the transmitter is reliably operated by a road user, a fire alarm will be output from the disaster prevention receiver panel, ensuring that road administrators are aware of the fire and can take swift and appropriate action. Furthermore, it will be possible to reliably coordinate the operation of other emergency equipment in response to the fire alarm, such as displaying a prohibition on tunnel entry on an electronic display installed at the tunnel entrance.

[0039] Furthermore, the storage door is equipped with a door contact detector. The "door contact detector" detects human contact with the door handle of the storage door. The structure and type of the detector are arbitrary, but for example, a touch switch that detects changes in pressure or capacitance caused by human hand contact and outputs a contact detection signal can be used.

[0040] In response to the door contact detector, the "control unit" maintains the locking mechanism on the storage door when the door contact detector detects human contact with the opening / closing handle of the storage door without detecting operation of the transmitter, and outputs voice and / or display guidance prompting operation of the transmitter.

[0041] Therefore, without operating the transmitter, when a road user places their hand on the door handle to open the storage door, the door contact detector detects the hand's contact with the door handle, and operation guidance is output. This makes it possible to output operation guidance that appropriately prompts the user to operate the transmitter at the timing when they attempt to open the storage door.

[0042] Furthermore, the storage door is equipped with a door open / close detector. Here, the "door open / close detector" is a device that detects when the storage door is opened or closed. Its structure, function, and type are arbitrary, but for example, a detection switch such as a limit switch can be used. The door detection switch turns the switch contacts off (or on) when the storage door is closed, and turns the switch contacts on (or off) when the storage door is opened.

[0043] In response to the door opening / closing detector, the control unit releases the lock on the storage door by energizing the electromagnetic drive unit (electromagnetic solenoid) of the door locking mechanism. If the door opening / closing detector detects that the storage door has opened, the control unit then stops energizing the electromagnetic drive unit (electromagnetic solenoid) of the door locking mechanism. Therefore, the period during which the storage door is released by energizing the electromagnetic drive unit (electromagnetic solenoid) is short, from the time a road user touches the door handle until the storage door begins to open, thus enabling power saving.

[0044] Furthermore, the door locking mechanism is equipped with a manual release mechanism that releases the locking mechanism of the storage door when the plunger is moved manually. Therefore, even if the pull-type electromagnetic solenoid, which functions as the electromagnetic drive unit, malfunctions, the locking mechanism of the storage door can be easily released by road users by operating the manual release mechanism, ensuring a high level of fail-safe capability.

[0045] The embodiment focuses on a "fire hydrant system" as an example of a "fire extinguishing equipment storage device." Here, a "fire hydrant system" is a type of emergency equipment installed in tunnels of expressways and motorways that are designated as fire-fighting areas. It consists of a housing installed in the fire-fighting area that houses or contains fire hoses and other fire hydrant equipment and fire extinguishers, and an emergency notification device such as a red indicator light or transmitter installed on an emergency notification door.

[0046] Furthermore, a "fire hydrant system" consists of a "fire hydrant storage unit" in which fire hydrant equipment is arranged or stored within a housing with a fire hydrant door, and a "fire extinguisher storage unit" in which fire extinguishers are arranged or stored within a housing with a fire extinguisher door. Thus, the "fire hydrant storage unit of a fire hydrant system" is one example of a "fire extinguishing equipment storage unit," and the "fire extinguisher storage unit of a fire hydrant system" is another example of a "fire extinguishing equipment storage unit."

[0047] Therefore, in the case of a "fire hydrant storage unit for a fire hydrant system," which is an example of a "fire extinguishing equipment storage device," the control unit, as in the case of the fire extinguishing equipment storage device described above, releases the lock that prevents the fire hydrant door from being opened by the door locking mechanism when operation of the transmitter is detected, allowing it to be opened. Furthermore, if the door contact detector detects human contact with the door handle of the fire hydrant door without operation of the transmitter being detected, it maintains the locking of the fire hydrant door by the door locking mechanism and outputs voice and / or display guidance prompting the operation of the transmitter.

[0048] Furthermore, in the case of the "fire extinguishing equipment storage unit," which is another example of a "fire extinguishing equipment storage unit," similar to the fire extinguishing equipment storage unit described above, the control unit releases the lock on the fire extinguisher door using the door locking mechanism when operation of the transmitter is detected, allowing it to be opened. Also, if the door contact detector detects human contact with the door handle of the fire extinguisher door without operation of the transmitter being detected, the locking mechanism maintains the lock and outputs voice and / or display guidance prompting operation of the transmitter.

[0049] Furthermore, the embodiment also includes a "fire extinguisher box" as another example of a "fire extinguishing equipment storage device." Here, a "fire extinguisher box" is a type of emergency equipment installed in tunnels of expressways and motorways that are areas to be extinguished, in which a fire extinguisher is arranged or stored inside a housing with a fire extinguisher door, and an emergency notification device including a transmitter is placed at a predetermined position in the housing.

[0050] In the case of a "fire extinguishing equipment storage device," which is another example of a "fire extinguishing equipment storage device," similar to the fire extinguishing equipment storage device described above, the control unit releases the lock on the fire extinguisher door using the door locking mechanism when operation of the transmitter is detected, allowing it to be opened. Furthermore, if the door contact detector detects human contact with the door handle of the fire extinguisher door without operation of the transmitter being detected, the door locking mechanism maintains the lock on the fire extinguisher door and outputs voice and / or display guidance prompting operation of the transmitter.

[0051] The following describes specific embodiments. The specific embodiments shown below describe the "fire hydrant storage section of a fire hydrant system," the "fire extinguisher storage section of a fire hydrant system," and the "fire extinguisher box," which are specific embodiments of the "fire extinguishing equipment storage device."

[0052] This section describes the case where the "fire extinguishing equipment storage device" is the "fire hydrant storage section of a fire hydrant system," the "storage door" is the "fire hydrant door," the "fire extinguishing equipment" is the "fire hydrant equipment," the "door fixing mechanism" is the "fire hydrant door electromagnetic solenoid," the "door contact detector" is the "fire hydrant door touch switch," and the "door opening / closing detector" is the "fire hydrant door detection switch."

[0053] Furthermore, we will explain the case where the "fire extinguishing equipment storage device" is the "fire extinguisher storage section of a fire hydrant system" or a "fire extinguisher box," the "storage door" is a "fire extinguisher door," the "fire extinguishing equipment" is a "fire extinguisher," the "door fixing mechanism" is a "fire extinguisher door electromagnetic solenoid," the "door contact detector" is a "fire extinguisher door touch switch," and the "door opening / closing detector" is a "fire extinguisher door detection switch."

[0055] [a. Fire hydrant system] A fire hydrant device, which is an example of a fire extinguishing equipment storage device of this embodiment, will be described in more detail. In this description, refer to Figure 1, which shows an overview of the tunnel emergency equipment, Figure 2, which shows the fire hydrant device, and Figure 3, which shows the internal structure of the fire hydrant device from the front with the door open.

[0056] (a1. Overview of tunnel emergency equipment) An overview of the tunnel emergency equipment will be described. As shown in Figure 1, the tunnel emergency equipment consists of wiring cables 14 from a disaster prevention receiving panel 12 installed in the electrical room of the tunnel facility, which are connected in stages to, for example, four fire hydrant devices 10(10-1)-10(10-4) installed in each longitudinal unit section of the tunnel.

[0057] Here, among the fire hydrant devices 10(10-1) to 10(10-4), the fire hydrant device 10(10-1) connected to the closest position in terms of wiring to the disaster prevention receiving panel 12 becomes the "first stage," and the fire hydrant device 10(10-4) connected to the furthest position becomes the "final stage."

[0058] The wiring cable 14 includes high-voltage wiring cables for commercial AC power and low-voltage wiring cables for a predetermined DC voltage power supply, and the low-voltage wiring cables include those composed of one or more signal lines and a common line.

[0059] (a2. Configuration of fire hydrant system) The configuration of the fire hydrant device 10(10-1) shown in Figure 2 will be explained in more detail. The same applies to the fire hydrant devices 10(10-2) to (10-4). As shown in Figure 2, the fire hydrant device 10(10-1) has a structure divided into a housing 10a which houses the fire hydrant and a housing 10b which houses the fire extinguisher, and decorative frames 11a and 11b are attached to the front of the housings 10a and 10b.

[0060] The door opening of the decorative frame 11a of the housing 10a is divided into upper and lower sections. A forward-tilting fire hydrant door 15 that opens downward on a hinge is installed on the lower side of the door opening, and a maintenance door 16 that opens upward on a hinge is installed on the upper side of the door opening. Inside the maintenance door, which is the fire hydrant storage section, fire hydrant equipment such as a fire hose with a nozzle attached and valves including a fire hydrant valve are stored. The fire hydrant door 15 is provided with a door handle 1510, and road users can open the fire hydrant door 15 by putting their hand on the door handle 1510 and pulling it towards them.

[0061] On the left side of the door opening of the decorative frame 11b of the housing 10b, there is a fire extinguisher door 18 that opens horizontally to the left by a hinge, and the fire extinguisher storage area inside can accommodate, for example, two fire extinguishers. The fire extinguisher door 18 is equipped with a door handle 1810, and road users can open the fire extinguisher door 18 by putting their hand on the door handle 1810 and pulling it towards them. In addition, a viewing window 1820 is provided on the lower side of the fire extinguisher door 18, allowing the presence or absence of fire extinguishers to be checked from the outside.

[0062] An emergency notification door 20 is provided on the right side of the door opening of the decorative frame 11b, which opens horizontally to the right by a hinge. The emergency notification door 20 is equipped with emergency notification equipment, such as a red indicator light 22, a transmitter 24, and a response lamp 26, and a telephone jack (not shown) is provided inside the housing 10b of the emergency notification door 20. Thus, the emergency notification device is composed of the red indicator light 22, transmitter 24, response lamp 26, and telephone jack provided on the emergency notification door 20. Note that the emergency notification door 20 is a concept that includes an electrical door, and the red indicator light 22, transmitter 24, response lamp 26, and telephone jack can be said to be electrical equipment provided on an electrical door.

[0063] The red indicator light 22 is always lit so that the location of the fire hydrant device 10 (10-1) can be seen from a distance. In the event of a fire, when a road user confirms the fire and presses the push button on the transmitter 24, the push button switch is turned on, a fire alarm signal (transmission signal) is sent to the disaster prevention receiver panel 12 installed in the electrical room, etc., and a fire alarm is output. In response, a response signal is sent from the disaster prevention receiver panel 12 to the fire hydrant device 10 (10-1), the red indicator light 22 flashes, and the response lamp 26 lights up.

[0064] (a3. Internal structure of a fire hydrant system) The internal structure of the fire hydrant device 10(10-1) shown in Figure 3 will be explained in detail. The same applies to fire hydrant devices 10(10-2) to (10-4).

[0065] As shown in Figure 3, the interior of the housing 10a, which serves as the fire hydrant storage section 17, is divided into a valve storage section 1710 and a hose storage section 1720. In the valve storage section 1710, a water supply pipe 55 drawn in from the outside is connected to a water tap 56, and also branches downward and is connected to a fire hose 62 via a fire hydrant valve 57 and an automatic pressure regulating valve 58.

[0066] The fire hydrant valve 57 is opened and closed by a fire hydrant valve opening / closing lever 60 located in the operation box 61. When a road user opens or closes the fire hydrant valve opening / closing lever 60, the fire hydrant valve 57 is opened and closed in conjunction with a known wire linkage mechanism located in the interlocking box 67, and a pump activation interlocking switch 74 located in the interlocking box 67 is turned on or off. In addition, a pump activation switch 76 for use by the fire brigade is located to the upper right of the water tap 56.

[0067] The hose storage section 1720 is equipped with a hose storage frame 66, which stores the fire extinguishing hose 62 that is pulled in from below by winding it inward clockwise or counterclockwise. A nozzle 64 is attached to the end of the fire extinguishing hose 62 that is pulled out through the hose guide (hose outlet) 68, and the nozzle 64 is detachably held in a nozzle holder 65. Inside the housing 10b (on the side with the fire extinguisher door 18) is the fire extinguisher storage section 19, which houses two fire extinguishers 34.

[0068] Terminal boxes 30 and 32 are installed on the rear of the fire extinguisher storage section 19. A red indicator light 22 provided on the emergency communication door 20 is connected to terminal box 30 via a wiring cable, and a transmitter 24, response lamp 26, and telephone jack 28 provided on the emergency communication door 20 are connected to terminal box 32 via a wiring cable. Furthermore, a pump start switch 76 and a pump start interlock switch 74 provided on the valve storage section 1710 are connected via a wiring cable.

[0069] A cable rack 70 is installed in the hose storage section 1720 inside the enclosure 10a. The cable rack 70 is connected to the terminal box 30 via high-voltage cables brought in from the outside, and also to the terminal box 32 via low-voltage cables brought in from the outside, and further connected to the pump start switch. 76 and pump start-linked switch 74 Connect to terminal box 32 via the wiring cable.

[0070] [b. Fire hydrant storage section of a fire hydrant system] A fire hydrant storage section of a fire hydrant system, which is an example of a specific embodiment of a fire extinguishing equipment storage device, will be described in more detail. Here, the fire hydrant storage section of a fire hydrant system, which is an example of a specific embodiment of a fire extinguishing equipment storage device, is provided with the fire hydrant door 15 shown in Figures 2 and 3. Cosmetic frame This refers to the device portion including the fire hydrant storage section 17 and the emergency notification door 20 on which the transmitter 24 is installed.

[0071] (b1. Door fixing mechanism for fire hydrant doors) The fire hydrant door 15 of the fire hydrant system is equipped with a door fixing mechanism. Under normal conditions, the door fixing mechanism fixes the fire hydrant door 15 in a position where it cannot be opened. When operation of the transmitter 24 is detected, the fixing mechanism is released, allowing the fire hydrant door 15 to be opened.

[0072] The structure and type of the door fixing mechanism for the fire hydrant door 15 are arbitrary, but for example, as shown in Figures 2 and 3, the fire hydrant door 15 is provided with a fire hydrant door electromagnetic solenoid 36 that functions as a fire hydrant door fixing mechanism. The fire hydrant door electromagnetic solenoid 36 fixes the fire hydrant door 15 in an inoperable state, and releases the fixing of the fire hydrant door 15 in an operational state, making it possible to open it. In addition, the fire hydrant door electromagnetic solenoid 36 is provided with a manual lock release part 42 exposed on the outside of the decorative frame 11a. The manual lock release part 42 allows the fire hydrant door 15 to be opened by manually releasing the fixing of the fire hydrant door 15 by the fire hydrant door electromagnetic solenoid 36.

[0073] In this embodiment, the operation to open the fire hydrant door 15 means that, with the fire hydrant door 15 released from its lock by the operation of the fire hydrant door electromagnetic solenoid 36, a road user pulls the door handle 1510 to release the lock and open the door.

[0074] (b2. Electromagnetic solenoid for fire hydrant door) The electromagnetic solenoid for fire hydrant doors will be explained in more detail. In this explanation, refer to Figure 4, which shows the fire hydrant door fixing mechanism equipped with the electromagnetic solenoid and manual lock release mechanism. Figure 4(A) shows a cross-section of the fire hydrant door fixing mechanism, Figure 4(B) shows the front view, and Figure 4(C) shows the cross-section along the cutting line aa in Figure 4(A).

[0075] As shown in Figure 4, the fire hydrant door electromagnetic solenoid 36 is located in a door opening where the fire hydrant door 15 is positioned. Cosmetic frame A cylindrical body 3610 is fixed to the back side of 11a by a mounting part 3612.

[0076] Inside the main body 3610 of the fire hydrant door electromagnetic solenoid 36, a cylindrical fixed magnetic pole section around which an electromagnetic coil is wound is arranged, and a plunger 3620, which functions as a push rod and acts as a movable magnetic pole section, is movably positioned within the cylindrical hole of the fixed magnetic pole section. When the electromagnetic coil is not energized, the plunger is activated by a coil spring or the like. 3620 The plunger 3620 protrudes from the main body 3610, and when the electromagnetic coil is energized, the electromagnetic force generated at the fixed magnetic pole portion causes the plunger 3620 to move inward towards the main body 3610. In this way, when the plunger is energized, 3620 An electromagnetic solenoid with a structure that pulls the current into the main body 3610 is known as a pull-type (retraction-type) electromagnetic solenoid.

[0077] The plunger 3620 of the fire hydrant door electromagnetic solenoid 36 protrudes from the through hole 3630 of the housing 11a when de-energized and is inserted into the fixing hole 3640 of the fire hydrant door 15 in the closed position, fixing the fire hydrant door 15 so that it does not open. When the electromagnetic coil of the fire hydrant door electromagnetic solenoid 36 is energized, the plunger 3620 moves as it is pulled into the main body 3610 by the electromagnetic force generated at the fixed magnetic pole part, and the fixing of the fire hydrant door 15 is released as it disengages from the fixing hole 3640 of the fire hydrant door 15.

[0078] (b3.Manual fixing release part) The manual lock release unit 42 will now be described in more detail. The manual lock release unit 42 is provided for the fire hydrant door electromagnetic solenoid 36. The manual lock release unit 42 releases the lock on the fire hydrant door 15 by the fire hydrant door electromagnetic solenoid 36 through manual operation. Its mechanism and structure are arbitrary, but for example, an operating shaft 4210 stands in a direction perpendicular to the plunger 3620, and the shaft end is taken out to the outside from a guide hole 4230 which is an elongated hole in the direction of the plunger axis formed in the decorative frame 11a, and an operating knob 4220 is attached to the shaft end.

[0079] Furthermore, corresponding to the operating knob 4220 located on the outside of the decorative frame 11a, an arrow-shaped manual release operation guide display section 4240 labeled "Manual Release" is provided on the outer surface of the fire hydrant door 15.

[0080] Therefore, if the fire hydrant door electromagnetic solenoid 36 malfunctions or otherwise causes the plunger 3620 to not be retracted and the fire hydrant door 15 to not be released even when the fire hydrant door electromagnetic solenoid 36 is energized, road users can slide the operating knob 4220 of the manual release unit 42 in the direction indicated by the arrow on the manual release operation guidance display unit 4240, thereby releasing the plunger via the operating shaft 4210. -3 The fixing can be released by pushing part 620 into the main body 3610 and pulling it out from the fixing hole 3640 of the fire hydrant door 15.

[0081] [c.Control unit] The control unit that controls the fire hydrant storage section of the fire hydrant system will be described in more detail. In this description, in addition to Figures 1 to 4, Figure 5, which shows the functional configuration of the control unit installed in the fire hydrant system, will be referred to.

[0082] (c1. Functional configuration of the control unit) The functional configuration of the control unit 72 will be explained in more detail. As shown in Figure 3, the control unit 72 is installed below the terminal boxes 30 and 32 on the rear surface of the fire extinguisher storage section 19 in the fire hydrant device 10 (10-1).

[0083] The control unit 72 shown in Figure 5 is composed of, for example, a computer circuit equipped with a CPU, memory, and various input / output ports, and realizes predetermined control functions by executing a control program stored in memory. Note that the control unit 72 is not limited to a computer circuit, but may also be a logic sequence circuit, relay sequence circuit, electronic control circuit, etc.

[0084] The control unit 72 has a transmitter switch contact 2410 connected to its input for detecting the operation of the transmitter 24. The control unit 72 also has a fire hydrant door touch switch 38 and a fire hydrant door detection switch 40, both included in the fire hydrant door input unit 86, connected to its input. The control unit 72 also has a fire hydrant door electromagnetic solenoid 36 connected to its output as the control target, and a transmitter guidance display unit 52 and a speaker unit 54, both included in the operation guidance unit 90, connected to its output. The fire extinguisher door touch switch 46 and fire extinguisher door detection switch 48, as well as the fire extinguisher door electromagnetic solenoid 44, included in the fire extinguisher input unit 88, are connected to the control unit 72 for control corresponding to the fire extinguisher storage section of the fire hydrant system, which will be described later.

[0085] When the control unit 72 detects operation of the transmitter 24, it controls the fire hydrant door electromagnetic solenoid 36 to release the lock that prevents the fire hydrant door 15 from being opened, thereby allowing it to be opened. Furthermore, when the control unit 72 detects human contact with the door handle 1510 of the fire hydrant door 15 via the fire hydrant door touch switch 38 without detecting operation of the transmitter 24, it maintains the lock of the fire hydrant door 15 by the fire hydrant door electromagnetic solenoid 36 (maintains the de-energized state) and outputs a predetermined voice message from the speaker unit 54 prompting operation of the transmitter 24. guidance The display unit 52 is controlled to light up or blink to prompt operation.

[0086] Furthermore, after the control unit 72 releases the fire hydrant door 15 by energizing the fire hydrant door electromagnetic solenoid 36, if the fire hydrant door detection switch 40 detects that the fire hydrant door 15 is open, it performs control to stop energizing the fire hydrant door electromagnetic solenoid 36.

[0087] (c2. Transmitter switch contacts) The transmitter switch contact 2410, which is provided as an input target for the control unit 72, will be described in more detail. In this description, refer to Figure 6, which is a wiring circuit diagram showing the wiring to the emergency notification device of the first-stage fire hydrant device 10 (10-1) shown in Figure 1, and Figure 7, which is a wiring circuit diagram showing the wiring to the emergency notification device of the final-stage fire hydrant device 10 (10-4).

[0088] As shown in Figure 6, the transmitter 24, response lamp 26, and telephone jack 28 provided in the first stage fire hydrant device 10(10-1), as well as the pump start switch 76 and pump start interlock switch 74 provided in the valve storage section 1710, are connected to the telephone line T, telephone common line TC, pump start line HA, manual notification line M, manual notification common line MC, response line MF, and response common line FC, which are drawn out from the disaster prevention receiving panel 12 and brought into the housing of the fire hydrant device 10(10-1), using the terminal block 80 of the terminal box 32 located inside the housing of the fire hydrant device 10(10-1).

[0089] Here, the terminal block 80 is assigned terminals to be used for each electrical device, and the telephone jack 28 has terminals T1, T2 and terminals TC1, TC2, and the transmitter 24 has terminals T1, T2 and TC1, TC2. Transmitter switch contact The 2420 has terminals M1, M2 and MC3, MC4, and response lamp 26. Transmitter switch contact 2430 has terminals MF1, MF2 and terminals FC3, FC4, and pump start Switch 76 and pump startup interlock Switch 74 Switch contact Terminals HA1, HA2 and MC3, MC4 are assigned to terminals 7610 and 7410.

[0090] Furthermore, terminals T1 and T2 of fire hydrant device 10(10-1) are wired together, and wiring is provided from terminal T2 to terminal T1 of the adjacent fire hydrant device 10(10-2) downstream. Similarly, terminals TC1 and TC2 are wired together, and wiring is provided from terminal TC2 of the adjacent fire hydrant device 10(10-2) downstream to terminal TC2 of the adjacent fire hydrant device 10(10-1) upstream. The same wiring relationships apply to terminals M1 and M2, terminals MC3 and MC4, terminals MF1 and MF2, terminals FC3 and FC4, terminals HA1 and HA2, and terminals MC3 and MC4.

[0091] Furthermore, the telephone line T, telephone common line TC, pump start line HA, manual notification line M, manual notification common line MC, response line MF, and response common line FC are connected as jumper lines from the first stage fire hydrant device 10(10-1) to the second stage fire hydrant device 10(10-2). This is also the case between the second stage fire hydrant device 10(10-2) and the third stage fire hydrant device 10(10-3), and between the third stage fire hydrant device 10(10-3) and the final stage fire hydrant device 10(10-4) shown in Figure 7. Note that the red indicator light 22 is not shown in the description or illustration because it uses the terminal block of the terminal box 30.

[0092] Of these emergency notification devices, the manual notification line M connected to the transmitter 24, which plays a particularly important role in the event of a fire, the pump start line HA connected to the pump start switch 76 and the pump start interlock switch 74, and the manual notification common line MC are monitored for disconnection in the terminal block 80, as shown in Figure 7. This is done by connecting a terminating resistor 82 between terminals M1 and MC4, to which the manual notification line M and the manual notification common line MC are connected, and by connecting a terminating resistor 84 between terminals HA1 and MC4, to which the pump start line HA and the manual notification common line MC are connected. Disconnection monitoring by the disaster prevention receiver panel 12 sequentially switches the connection between the manual notification line M and the manual notification common line MC, and the pump start line HA and the manual notification common line MC to the disconnection monitoring circuit at predetermined intervals, and outputs a predetermined fault alarm when a disconnection is detected.

[0093] As shown in Figure 6, the transmitter 24 provided in the first stage fire hydrant device 10 (10-1) is equipped with three transmitter switch contacts 2410, 2420, and 2430 having a locking structure.

[0094] The transmitter switch contact 2410 is connected to the control unit 72 as an input target, and when the push button on the transmitter 24 is turned on, the control unit 72 detects that the transmitter 24 has been operated.

[0095] Transmitter The switch contact 2420 is connected via terminal block 80 between the manual notification line M and the manual notification common line MC. When the transmitter 24 is operated... Transmitter When switch contact 2420 is turned on, a fire alarm signal current flows from the positive manual alarm line M to the negative manual alarm common line MC, the fire alarm signal is transmitted to the fire prevention receiver panel 12, and a fire alarm is output.

[0096] Transmitter The switch contact 2430 is connected in series with the response lamp 26. One end of the response lamp 26 is connected to the response line MF via terminal block 80, and the other end is connected to the transmitter 24. Transmitter It is connected to the manual notification common line MC via the switch contact 2430 and terminal block 80, and is activated by the operation of the transmitter 24. Transmitter The light illuminates upon receiving a signal voltage from the manual notification common line MC drawn from the disaster prevention receiver panel 12, provided that switch contact 2430 is turned ON.

[0097] The switch contact 7610 of the pump start switch 76 and the switch contact 7410 of the pump start interlock switch 74 are connected in parallel. One end of the parallel connection is connected to the pump start line HA via terminal block 80, and the other end of the parallel connection is connected to the manual notification common line MC via terminal block 80. Therefore, when the switch contact 7410 of the pump start switch 74 or the switch contact 7610 of the pump start interlock switch 76 is turned on, a signal current flows from the pump start line HA to the manual notification common line MC, and a pump start signal is transmitted to the disaster prevention receiving panel 12.

[0098] Furthermore, the telephone jack 28 is connected to the telephone line T and the telephone common line TC via the terminal block 80, and by connecting the plug of the telephone carried by the staff member to the telephone jack 28, communication with the disaster prevention receiving panel 12 becomes possible. The wiring circuit for such electrical equipment is similar for the final stage fire hydrant device 10 (10-4) shown in Figure 7.

[0099] (c3. Fire hydrant door touch switch) The fire hydrant door touch switch 38, which is provided as an input target for the control unit 72, will be described in more detail.

[0100] As shown in Figure 2, the door handle 1510 of the fire hydrant door 15 is equipped with a fire hydrant door touch switch 38, which functions as a door contact detector. The fire hydrant door touch switch 38 detects human contact with the door handle 1510 of the fire hydrant door 15. Its configuration, function, and type are arbitrary, but for example, a pressure-sensitive switch that turns on when it detects the pressure applied to the handle when a person operates it, or a capacitive switch that turns on when it detects the change in capacitance when a person touches the handle, can be used.

[0101] (c4. Fire hydrant door detection switch) The fire hydrant door detection switch 40, which is provided as an input target for the control unit 72, will be described in more detail.

[0102] As shown in Figure 2, the fire hydrant door 15 is equipped with a fire hydrant door detection switch 40 that functions as a door opening / closing detector. The fire hydrant door detection switch 40 is a switch that is activated by the opening and closing of the fire hydrant door 15. Its structure and type are arbitrary, but for example, a limit switch equipped with a switch knob or switch lever that extends and retracts in conjunction with the opening and closing of the door can be used. As an example, the fire hydrant door detection switch 40 is turned off when the fire hydrant door 15 is closed and turned on from the beginning of opening until the door is fully open.

[0103] Here, the relationship between the fire hydrant door touch switch 38 and the fire hydrant door detection switch 40 is that the fire hydrant door touch switch 38 is activated regardless of whether the fire hydrant door 15 is open or closed, and a person is detected. doorThe handle 1510 is turned on when touched, while the fire hydrant door detection switch 40 is turned on when the fire hydrant door 15 begins to open. When a person pulls the door handle 1510 to open the fire hydrant door 15, the fire hydrant door touch switch 38 turns on first, followed by the fire hydrant door detection switch 40.

[0104] (c5. Transmitter Information Display Unit) The transmitter guidance display unit 52, which is provided as an output target of the control unit 72, will be described in more detail.

[0105] As shown in Figure 2, the transmitter 24 installed on the emergency communication door 20 is equipped with a transmitter guidance display unit 52. The structure and type of the transmitter guidance display unit 52 are arbitrary, but for example, it is a light-emitting display panel with LEDs as the light source installed around the transmitter 24, and the light-emitting display panel provides guidance to encourage operation of the transmitter 24, for example by flashing.

[0106] (c6. Speaker section) The speaker unit 54, which is provided as an output target for the control unit 72, will be described in more detail.

[0107] As shown in Figure 2, the speaker unit 54 is positioned, for example, below the emergency notification door 20. When the fire hydrant door touch switch 38 detects human contact with the door handle 1510 of the fire hydrant door 15 without detecting operation of the transmitter 24, the speaker unit 54 outputs a predetermined voice message prompting operation of the transmitter 24 via an audio signal output from the control unit 72. This voice message is arbitrary, but for example, it repeatedly outputs "Beep beep beep. The transmitter has not been operated. Please check for a fire and operate the transmitter to report the fire. The fire hydrant door will be released upon fire reporting."

[0108] [d. Fire extinguisher storage section of a fire hydrant system] A fire extinguisher storage section of a fire hydrant system, which is another embodiment of the fire extinguishing equipment storage device, will be described in more detail. In this description, in addition to Figures 2 to 4, Figure 5, which shows the functional configuration of the control unit provided in the fire hydrant system, will be referred to.

[0109] (d1. Door fixing mechanism for fire extinguisher doors) The fire extinguisher door 18 of the fire hydrant system is equipped with a door fixing mechanism. The door fixing mechanism normally fixes the fire extinguisher door 18 in a position where it cannot be opened, and when operation of the transmitter 24 is detected, it releases the fixing of the fire extinguisher door 18, making it possible to open it. ru .

[0110] (d2. Electromagnetic solenoid on fire extinguisher door) As shown in Figures 2 and 3, the fire extinguisher door 18 is equipped with a fire extinguisher door electromagnetic solenoid 44 that functions as a door fixing mechanism. When the fire extinguisher door electromagnetic solenoid 44 is not energized and inactive, it fixes the fire extinguisher door 18 in a state where it cannot be opened. When the push button on the transmitter 24 is pressed and a fire alarm signal is transmitted, it is energized and activated, releasing the fire extinguisher door 18 from its fixed position.

[0111] Furthermore, the fire extinguisher door electromagnetic solenoid 44 is provided with a manual lock release unit 50. The manual lock release unit 50 allows manual operation to release the locking of the fire hydrant door 15 by the fire extinguisher door electromagnetic solenoid 44.

[0112] The details of the fire extinguisher door electromagnetic solenoid 44 and the manual lock release mechanism 50 are the same as those of the fire hydrant door electromagnetic solenoid 36 and the manual lock release mechanism 42 shown in Figure 4, so their explanation will be omitted.

[0113] [d3. Control of the fire extinguisher storage unit] The control unit that controls the fire extinguisher storage section of the fire hydrant system will be explained in more detail. The control unit that controls the fire extinguisher storage section of the fire hydrant system is the same as the control unit 72 that controls the fire hydrant storage section of the fire hydrant system shown in Figure 5.

[0114] The input to the control unit 72 shown in Figure 5 is connected to the transmitter switch contact 2410 in order to perform control corresponding to the fire extinguisher storage section of the fire hydrant system, and also to the fire extinguisher doorThe input unit 88 is connected to a fire extinguisher door touch switch 46 and a fire extinguisher door detection switch 48. The output of the control unit 72 is connected to a fire extinguisher door electromagnetic solenoid 44 as a control target corresponding to the fire extinguisher door 18, and the transmitter guidance display unit 52 and speaker unit 54, which are included in the operation guidance unit 90, are also connected. The transmitter switch contact 2410, transmitter guidance display unit 52 and speaker unit 54 are common to the control input unit and control target corresponding to the fire hydrant storage unit of the fire hydrant device described above.

[0115] In order to control the fire extinguisher storage section of the fire hydrant system, the control unit 72, upon detecting operation of the transmitter 24, performs control to release the lock that prevents the fire extinguisher door 18 from being opened by energizing the fire extinguisher door electromagnetic solenoid 44, thereby enabling it to be opened. In this embodiment, the operation to open the fire extinguisher door 18 means that, with the fire extinguisher door 18 released from its lock by energizing the fire extinguisher door electromagnetic solenoid 44, a road user unlocks and opens the door by operating the door handle 1810.

[0116] Furthermore, if the control unit 72 detects human contact with the door handle 1810 of the fire extinguisher door 18 via the fire extinguisher door touch switch 46 without detecting operation of the transmitter 24, it maintains the fire extinguisher door 18 fixed by de-energizing the fire extinguisher door electromagnetic solenoid 44, outputs a predetermined voice message from the speaker unit 54 prompting operation of the transmitter 24, and controls the transmitter guidance display unit 52 to, for example, blink.

[0117] Furthermore, after the control unit 72 releases the fire extinguisher door 18 by energizing the electromagnetic coil of the fire extinguisher door electromagnetic solenoid 44, if the fire extinguisher door detection switch 48 detects that the fire extinguisher door 18 is open, it performs control to stop energizing the electromagnetic coil of the fire extinguisher door electromagnetic solenoid 44.

[0118] Details of the transmitter switch contact 2410, which is provided as an input target for the control unit 72 corresponding to the fire extinguisher storage section of the fire hydrant system, have already been explained with reference to Figures 6 and 7. Furthermore, the details of the fire extinguisher door touch switch 46 and the fire extinguisher door detection switch 48 are the same as those of the fire hydrant door touch switch 38 and the fire hydrant door detection switch 40, which have already been explained, so their respective explanations are omitted. Also, details of the transmitter guidance display unit 52, which is provided as an output target for the control unit 72 corresponding to the fire extinguisher door 18, are the same as those for the fire hydrant door 15, so they are omitted.

[0119] The speaker unit 54, which is provided as a control target of the control unit 72 corresponding to the fire extinguisher storage section of the fire hydrant system, outputs a predetermined voice message prompting the user to check for a fire and operate the transmitter when the fire extinguisher door touch switch 46 detects human contact with the door handle 1810 of the fire extinguisher door 18 without detecting operation of the transmitter 24. This voice message is arbitrary, but for example, it repeatedly outputs "Beep beep beep The transmitter has not been operated. Please check for a fire and operate the transmitter to report the fire. The fire extinguisher door will be released when a fire is reported."

[0120] [e. Control operation of fire hydrant systems] The control operation of the fire hydrant system by the control unit 72 in Figure 5 will be explained in more detail. In this explanation, refer to Figure 8, which is a flowchart showing the control operation of the fire hydrant system by the control unit 72 in Figure 5.

[0121] As shown in Figure 8, in the operational state after the control unit 72 of the fire hydrant system is activated, the control unit 72 monitors human contact with the door handle 1510 of the fire hydrant door 15 by the fire hydrant door touch switch 38, that is, operations in which road users place their hands on the door handle 1510 and attempt to open the fire hydrant door 15 (step S1).

[0122] If a vehicle fire occurs in the tunnel due to an accident or other reason, and a road user attempts to open the fire hydrant door 15 without operating the transmitter 24, the system will detect that the fire hydrant door touch switch 38 is ON (Yes in step S1), and a system corresponding to the transmitter 24 will be activated. Transmitter The information display unit 52 is driven to flash, and the speaker unit 54 outputs an operational guidance voice message prompting the user to check for a fire and report the fire by operating the transmitter 24 (step S2).

[0123] When a road user presses the button on the transmitter 24 in response to the output of an operation guidance prompting them to check for a fire and report it, the transmitter switch contact 2410 turns on, confirming that the transmitter 24 has been operated (Yes in step S3), and the fire hydrant door electromagnetic solenoid 36 is energized, releasing the lock on the fire hydrant door 15 (step S4), making it possible to open the fire hydrant door 15.

[0124] Next, when the fire hydrant door detection switch 40 turns on and it is determined that the fire hydrant door 15 is open (Yes in step S5), the power to the fire hydrant door electromagnetic solenoid 36 is stopped (step S6). If the fire extinguisher door touch switch 46 is off without the fire extinguisher door 18 being opened, the monitoring returns to the initial fire hydrant door touch switch 38 (No in step S7).

[0125] On the other hand, if the fire is small in scale, road users will use fire extinguishers to put out the fire. Therefore, if a road user attempts to open the fire extinguisher door 18 without operating the transmitter 24, the control unit 72 detects that the fire extinguisher door touch switch 46 is ON (Yes in step S7), and the control unit provided in response to the transmitter 24 Transmitter The information display unit 52 is driven to flash, and the speaker unit 54 outputs an operational guidance voice message prompting the user to check for a fire and report the fire by operating the transmitter 24 (step S8).

[0126] When a road user presses the button on the transmitter 24 in response to the output of an operation guidance prompting them to check for a fire and report it, the transmitter switch contact 2410 turns on, confirming that the transmitter 24 has been operated (Yes in step S9), and the fire extinguisher door electromagnetic solenoid 44 is energized, releasing the lock on the fire extinguisher door 18 (step S10), making it possible to open the fire extinguisher door 18.

[0127] Next, when the fire extinguisher door detection switch 48 is turned on and it is determined that the fire extinguisher door 18 is open (Yes in step S11), the power to the fire extinguisher door electromagnetic solenoid 44 is stopped (step S12), and the monitoring returns to the initial fire hydrant door touch switch 38 (step S1).

[0128] [f. Fire extinguisher box] A fire extinguisher box, which is another specific embodiment of the fire extinguishing equipment storage device, will be described in more detail. In this description, refer to Figure 9, which shows the fire extinguisher box; Figure 10, which is a block diagram showing the functional configuration of the control unit provided in the fire extinguisher box; and Figure 11, which is a flowchart showing the control operation of the control unit in Figure 10 to the control box.

[0129] (f1: Fire extinguisher box configuration) The configuration of the fire extinguisher box will be explained in more detail. The fire extinguisher box 100 of this embodiment corresponds to the configuration obtained by taking out the housing 10b side of the fire hydrant device 10(10-1) shown in Figure 2. As shown in Figure 9, a fire extinguisher door 18 that opens horizontally to the left by a hinge is provided on the left side of the door opening of the decorative frame 102 of the housing 101 of the fire extinguisher box 100, and two fire extinguishers can be stored inside the fire extinguisher storage section.

[0130] The fire extinguisher door 18 is equipped with a door handle 1810. When a road user puts their hand into the door handle 1810 and pulls it towards them, the lock is released and the fire extinguisher door 18 can be opened. In addition, a viewing window 1820 is provided on the lower side of the fire extinguisher door 18, allowing the presence or absence of a fire extinguisher to be checked from the outside.

[0131] An emergency notification door 20 is provided on the right side of the door opening of the decorative frame 102, which opens horizontally to the right by a hinge. The emergency notification door 20 is equipped with emergency notification device components, such as a red indicator light 22, a transmitter 24, and a response lamp 26, and a telephone jack is provided inside the housing 102 of the emergency notification door 20. Thus, the emergency notification device is configured with the red indicator light 22, transmitter 24, response lamp 26, and telephone jack provided on the emergency notification door 20.

[0132] The red indicator light 22 is always illuminated so that the location of the fire extinguisher box 100 can be seen from a distance. In the event of a fire, when a road user presses the transmitter 24, the push button switch on the transmitter 24 is turned on, and a fire alarm signal (transmission signal) is sent to the disaster prevention receiving panel 12 installed in the electrical room, etc., and a fire alarm is output. In response, a response signal is sent from the disaster prevention receiving panel 12 to the fire extinguisher box 100. to Upon transmission, the red indicator light 22 flashes and the response lamp 26 lights up.

[0133] The transmitter 24 is surrounded by a transmitter guidance display unit 52. The structure and function of the transmitter guidance display unit 52 are arbitrary, but for example, it is a light-emitting display board with an LED as the light source, and if a road user attempts to open the fire extinguisher door 18 without operating the transmitter 24, the light-emitting display board will light up or flash to provide guidance prompting the user to operate the transmitter 24.

[0134] Furthermore, a speaker unit 54 is provided on the lower side of the emergency notification door 20. The speaker unit 54 outputs a predetermined voice message prompting road users to operate the transmitter 24 if they attempt to open the fire extinguisher door 18 without operating the transmitter 24.

[0135] The fire extinguisher door 18 is equipped with a fire extinguisher door electromagnetic solenoid 44, which functions as a door fixing mechanism. The fire extinguisher door electromagnetic solenoid 44 fixes the fire extinguisher door 18 in an unpowered, non-operating state, and releases the fixing of the fire extinguisher door 18 in an operated state when powered. The fire extinguisher door electromagnetic solenoid 44 is also equipped with a manual fixing release unit 50. The manual fixing release unit 50 allows the fire extinguisher door 18 to be opened by manually releasing the fixing of the fire extinguisher door 18 by the fire extinguisher door electromagnetic solenoid 44. Details of the fire extinguisher door electromagnetic solenoid 44 and the manual fixing release unit 50 are the same as those of the fire hydrant door electromagnetic solenoid 36 and manual fixing release unit 42 shown in Figure 4, so their explanation will be omitted.

[0136] A fire extinguisher door touch switch 46 is provided on the door handle 1810 of the fire extinguisher door 18. The fire extinguisher door touch switch 46 detects human contact with the door handle 1810.

[0137] The fire extinguisher door 18 is equipped with a fire extinguisher door detection switch 48, which functions as a fire extinguisher door opening / closing detector. The fire extinguisher door detection switch 48 is activated by the opening and closing of the fire extinguisher door 18. For example, a limit switch is used, which is off when the fire extinguisher door 18 is closed and on when the fire extinguisher door 18 is open. The details of the fire extinguisher door touch switch 46 and the fire extinguisher door detection switch 48 are the same as those of the fire hydrant door touch switch 38 and fire line door detection switch 40 shown in Figure 2, so their explanation will be omitted.

[0138] (f2. Functional configuration of the control unit) The control unit provided in the fire extinguisher box 100 will be described in more detail. As shown in Figure 10, the control unit 720 provided in the fire extinguisher box 100 corresponds to a functional configuration that excludes the fire hydrant door touch switch 38 and the fire hydrant door detection switch 40 of the fire hydrant input unit 86 for the control unit 72 of the fire hydrant system shown in Figure 5, and also excludes the fire hydrant door electromagnetic solenoid 36.

[0139] The functional configuration of the control unit 720 will now be explained in more detail. The control unit 720 shown in Figure 10 is composed of, for example, a computer circuit equipped with a CPU, memory, and various input / output ports, and realizes predetermined control functions by executing a control program stored in memory.

[0140] The control unit 720 has a transmitter switch contact 2410 connected to its input for detecting the operation of the transmitter 24. The control unit 720 also has a fire extinguisher door touch switch 46 and a fire extinguisher door detection switch 48 connected to its input. The control unit 720 also has a fire extinguisher door electromagnetic solenoid 44 connected to its output as a control target, as well as a transmitter guidance display unit 52 and a speaker unit 54, which are part of the operation guidance unit 90.

[0141] When the control unit 720 detects operation of the transmitter 24, it controls the fire extinguisher door electromagnetic solenoid 44 to release the lock that prevents the fire extinguisher door 18 from being opened, thereby allowing it to be opened. Furthermore, if the control unit 720 detects human contact with the door handle 1810 of the fire extinguisher door 18 via the fire extinguisher door touch switch 46 without detecting operation of the transmitter 24, it de-energizes the fire extinguisher door electromagnetic solenoid 44 to maintain the lock on the fire extinguisher door 18, and outputs a predetermined voice message from the speaker unit 54 prompting operation of the transmitter 24. guidance The display unit 52 is controlled to light up or blink to prompt operation.

[0142] Furthermore, after the fire extinguisher door electromagnetic solenoid 44 is energized to release the fire extinguisher door 18, the control unit 720 performs control to stop the energization of the fire extinguisher door electromagnetic solenoid 44 if the fire extinguisher door detection switch 48 detects that the fire extinguisher door 18 is open.

[0143] (f3. Control operation of the fire extinguisher box) The control operation of the fire extinguisher box by the control unit 720 in Figure 10 will be explained in more detail. As shown in Figure 11, in the operating state after the control unit 720 of the fire extinguisher box 100 is activated, the control unit 720 monitors human contact with the door handle 1810 of the fire extinguisher door 18 by the fire extinguisher door touch switch 46, that is, the operation in which a road user places their hand on the door handle 1810 and attempts to open the fire extinguisher door 18 (step S21).

[0144] If a vehicle fire occurs in the tunnel due to an accident or other reason, and a road user attempts to open the fire extinguisher door 18 without operating the transmitter 24, the system detects that the fire extinguisher door touch switch 46 is ON (Yes in step S21), causes the transmitter guidance display unit 52, which is provided in conjunction with the transmitter 24, to flash, and outputs an operation guidance message from the speaker unit 54 urging the user to check for a fire and report the fire by operating the transmitter 24 (step S22). In this case, the voice message may be, for example, "Beep beep beep. The transmitter has not been operated. Please check for a fire and operate the transmitter to report the fire. The fire extinguisher door will be released once the fire is reported."

[0145] When a road user presses the button on the transmitter 24 in response to the output of an operation guidance prompting them to check for a fire and report it, the transmitter switch contact 2410 turns on, confirming that the transmitter 24 has been operated (Yes in step S23), and the fire extinguisher door electromagnetic solenoid 44 is energized, releasing the lock on the fire extinguisher door 18 (step S24), making it possible to open the fire extinguisher door 18.

[0146] Next, when the fire extinguisher door detection switch 48 is turned on and it is determined that the fire extinguisher door 18 is open (Yes in step S25), the power to the fire extinguisher door electromagnetic solenoid 44 is stopped (step S26), and the monitoring returns to the initial fire extinguisher door touch switch 46 (step S21).
