Description

Technical Field

[0001] The present invention relates to a fire hydrant device in which a nameplate displaying an operation method of a fire hydrant is arranged on the back surface (back of the door) of a fire hydrant door that is opened when using the fire hydrant.

Background Art

[0002] Conventionally, fire hydrant devices have been installed in tunnels such as highways and motorways as emergency facilities in the tunnels. As shown in FIG. 4, a conventional fire hydrant device 10 includes a fire hose 18 with a water discharge nozzle 16 attached to its tip and valves including a fire hydrant valve stored in a fire hydrant storage section of a housing 12 having a fire hydrant door 14.

[0003] Here, in the description of FIG. 4, the X - Y - Z directions are perpendicular to each other. Specifically, when looking at the front of the fire hydrant device as the front, the X direction is the left - right direction, the Y direction is the up - down direction, and the Z direction is the front - back direction. Also, the +X side in the X direction is the right side, the -X side is the left side, the +Y side in the Y direction is the upper side, the -Y side is the lower side, the +Z side in the Z direction is the front side, and the -Z side is the back side. This also applies to FIGS. 1 to 3 showing embodiments of the present invention.

[0004] Also, on the back surface of the fire hydrant door 14, a fire hydrant valve opening and closing lever 20 for opening and closing the fire hydrant valve is provided. Further, a hose guide 22 stands on the back surface of the fire hydrant door 12, and the fire hose 18 drawn out from inside the housing 12 is drawn out through a nozzle holder 24, and the water discharge nozzle 16 connected to the tip of the fire hose 18 is detachably held by the nozzle holder 24 on the back surface of the fire hydrant door 12.

[0005] Furthermore, behind the fire hydrant valve opening and closing lever 20 provided on the back surface of the fire hydrant door 14, a nameplate 70 displaying the operation method of the fire hydrant device 10 is erected and arranged so as to be inclined obliquely upward.

Summary of the Invention

Problems to be Solved by the Invention

[0008] By the way, when using such a conventional fire hydrant device 10, after operating the transmitter provided in the fire hydrant device to report a fire, open the fire hydrant door 14, take out the water discharge nozzle 16 held on the back of the door, open the fire hydrant valve by operating the fire hydrant valve opening / closing lever 20, and pull out the fire hose 18 while discharging water from the water discharge nozzle 16. Also, the above operation of using the fire hydrant device 10 is not only actually performed at the time of a fire but also performed in regular inspections. In particular, the frequency is higher during inspections.

[0009] When the fire hose 18 is pulled out from the fire hydrant device 10 in a water flow state like this, the fire hose 18 wound inside the housing 12 is pulled out while swinging greatly when it comes out of the hose outlet, and the fire hose 18 may strongly hit the nameplate 70 standing on the back of the door, and the nameplate 70 may crack or break.

[0010] In addition, when the fire hose 18 is pulled out, a hose guide 22 is provided to smoothly pull it out, and a guard 21 is provided to prevent the fire hydrant valve opening / closing lever 20 operated to the open position from returning. However, the trajectory when the hose is pulled out cannot be controlled up to the point where it hits the nameplate 70, and an event occurs where it hits the nameplate, and at that time, the nameplate may be damaged or cracked.

[0011] To solve this problem, it is conceivable to increase the strength of the nameplate or divide the nameplate into, for example, three parts and arrange them in places where it is difficult for the fire hose to hit. However, if the thickness is increased to increase the strength of the nameplate, the nameplate becomes heavy, the mounting structure becomes complicated, and the cost increases. In addition, when the nameplate is divided and arranged dispersedly, there is a problem that the operation order becomes difficult to understand due to the dispersed arrangement.

[0012] An object of the present invention is to provide a fire hydrant device capable of maintaining the display function of the operation method even if the nameplate on which the operation method of the fire hydrant device is displayed is damaged due to hose pulling out during a fire and during inspection.

Means for Solving the Problem

[0013] (Fire Hydrant Device) The present invention is a housing installed in a tunnel, fire hydrant equipment including a fire hose and a fire hydrant valve housed in the housing and having a water discharge nozzle, a fire hydrant door provided at the front opening of the housing so as to be openable and closable about the lower end as an axis, and a fire hydrant device provided with a hose guide through which a fire hose leading to a water discharge nozzle is inserted and a fire hydrant valve opening / closing lever for opening and closing the fire hydrant valve on the back surface of the fire hydrant door, having a first nameplate and a second nameplate on which the operation method of the fire hydrant device is displayed, the first nameplate is arranged on the back surface of the fire hydrant door behind the fire hydrant valve opening / closing lever, the second nameplate is characterized in that it is arranged on the back surface of the fire hydrant door behind the hose guide.

[0014] (Arrangement of the First Nameplate and the Second Nameplate) The first nameplate is an plate member with a nameplate seal attached to the back surface of the fire hydrant door. When viewed from the front of the fire hydrant door with the display surface open in the door open state, it is erected and inclined so that the front is low and the back side is high. The second nameplate has a nameplate seal attached to the back surface of the fire hydrant door so that the display surface faces upward in the door open state.

[0015] (Protective plate member of nameplate seal) A transparent protective plate member is attached to each of the nameplate seals of the first nameplate and the second nameplate.

Effect of the invention

[0016] (Effect of the fire hydrant device) The present invention includes a housing installed in a tunnel, fire hydrant equipment including a fire hose with a water discharge nozzle and a fire hydrant valve housed in the housing, and a fire hydrant door provided at the front opening of the housing so as to be openable and closable about a lower end as an axis. A fire hydrant device provided with a hose guide through which a fire hose leading to a water discharge nozzle is inserted and a fire hydrant valve opening / closing lever for opening and closing the fire hydrant valve on the back surface of the fire hydrant door, having a first nameplate and a second nameplate on which an operation method of the fire hydrant device is displayed. The first nameplate is disposed on the back surface of the fire hydrant door behind the fire hydrant valve opening / closing lever, and the second nameplate is disposed on the back surface of the fire hydrant door behind the hose guide. Therefore, even if a phenomenon occurs in which the fire hose swings greatly as it is pulled out from the housing, the first nameplate and the second nameplate are dispersedly arranged at different positions on the back surface of the fire hydrant door. Even if the fire hose hits and damages one of the nameplates during an operation in case of a fire or during inspection, the other nameplate can function to continuously display the operation method.

[0017] (Effect of the arrangement of the first nameplate and the second nameplate) In addition, the first nameplate is an upright plate member with a nameplate seal attached to the back surface of the fire hydrant door. When viewed from the front of the fire hydrant door with the display surface open in the door-open state, it is inclined so that the front is low and the back side is high. The second nameplate has a nameplate seal attached to the back surface of the fire hydrant door so that the display surface faces upward in the door-open state. Therefore, while the first nameplate is easy to see, the fire hose is likely to hit it. However, since the second nameplate has a nameplate seal attached to the back surface of the fire hydrant door, it is difficult for the fire hose to hit it. Even if the fire hose hits it, since it is arranged in close contact with the back surface of the door, it is not assumed that it will crack or break. Even if the first nameplate is damaged, the second nameplate can reliably back up the display of the operation method.

[0018] (Effect of the protective plate member of the nameplate seal) In addition, since a transparent protective plate member is attached to each of the nameplate seals of the first nameplate and the second nameplate, the nameplate seal will not be damaged even if the fire hose hits or rubs against it.

Embodiments for Carrying Out the Invention

[0020] Hereinafter, embodiments of the 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 by the following embodiments.

[0021] [Basic Concept of the Embodiment] First, the basic concept of the embodiment will be described. The embodiment generally relates to a fire hydrant device in which a fire hose stored in a hose storage section inside a housing is pulled out during a fire fighting operation.

[0022] Here, the "fire hydrant device" is a type of emergency equipment installed, for example, in a tunnel on an expressway or an automobile-only road, which is a fire target area. Inside a housing installed in the tunnel, fire hydrant equipment including a fire hose equipped with a water discharge nozzle and a fire hydrant valve is stored, and a fire hydrant door is provided at the front opening of the housing so as to be openable and closable about the lower end as an axis. Further, on the back surface of the fire hydrant door, a hose guide through which a fire hose leading to the water discharge nozzle is inserted and a fire hydrant valve opening / closing lever for opening and closing the fire hydrant valve are provided.

[0023] Further, the "fire hydrant device" of the embodiment has a first nameplate and a second nameplate on which an operation method of the fire hydrant device is displayed.

[0024] Here, the "first nameplate" is arranged on the back surface of the fire hydrant door behind the fire hydrant valve opening / closing lever. Further, the "second nameplate" is arranged on the back surface of the fire hydrant door behind the hose guide.

[0025] Therefore, even if a phenomenon occurs in which the fire hose swings greatly as it is pulled out from the housing, since the first nameplate and the second nameplate are dispersedly arranged at different positions on the back surface of the fire hydrant door, even if the fire hose hits the first nameplate and is damaged, the second nameplate can function to continuously display the operation method.

[0026] Further, the "first nameplate" is an upright plate member with a nameplate seal attached to the back surface of the fire hydrant door, inclined so that the front side is lower and the back side is higher when viewed from the front of the fire hydrant door with the display surface open in the door open state. Further, the "second nameplate" has a nameplate seal attached to the back surface of the fire hydrant door so that the display surface faces upward in the door open state.

[0027] Therefore, while the "first nameplate" is easy to read, the fire hose is likely to hit it. On the other hand, since the nameplate seal is attached to the back surface of the fire hydrant door for the "second nameplate", it is difficult for the fire hose to hit it. Even if the fire hose hits it, since it is arranged in close contact with the back surface of the door, it is not assumed that it will crack or break. Even if the first nameplate is damaged, the second nameplate can surely back up the display of the operation method.

[0028] In addition, a transparent protective plate member is attached to each of the nameplate seals of the first nameplate and the second nameplate. In this case, the nameplate seal is protected by the protective plate member, and even if the fire hose hits or rubs against it, the nameplate seal will not be damaged.

[0029] [Specific Content of the Embodiment] Hereinafter, the fire hydrant device of a specific embodiment will be described in detail as follows. a. Fire Hydrant Device a1. Outline of the Fire Hydrant Device a2. Internal Structure of the Fire Hydrant Storage Section b. First Nameplate and Second Nameplate c. Modification Example of the Present Invention

[0030] [a. Fire Hydrant Device] Regarding the fire hydrant device according to the present embodiment, it will be described separately for the outline and the internal structure of the fire hydrant device. In this description, reference is made to FIG. 1 showing the fire hydrant device of the present invention in an open state of the fire hydrant door, FIG. 2 showing the fire hydrant device shown in FIG. 1 from the front, and FIG. 3 showing the fire hydrant device shown in FIG. 1 from the plane.

[0031] (a1. Outline of the Fire Hydrant Device) The outline of the fire hydrant device according to the present embodiment will be described. As shown in FIGS. 1 to 3, the fire hydrant device 10 has a structure divided into a housing 12 whose interior is a fire hydrant storage section and a housing 13 whose interior is a fire extinguisher storage section, and decorative frames 1210 and 1310 are attached to the front surfaces of the housings 12 and 13.

[0032] The door opening of the decorative frame 1210 of the housing 12 is divided vertically. An inclined fire hydrant door 14 that opens downward by a hinge is provided below the door opening, and a maintenance door 15 that opens upward by a hinge is provided above the door opening. Inside the fire hydrant storage section, valves including a fire hose 18 and a fire hydrant valve 40 are stored as fire hydrant equipment. A door handle is provided on the fire hydrant door 14. By inserting a hand into the door handle and pulling it forward, the lock is released and the fire hydrant door 14 can be opened as shown in the figure.

[0033] As shown in FIGS. 2 and 3, a fire extinguisher door 26 that opens horizontally to the left by a hinge is provided on the left side of the door opening of the decorative frame 1310 of the housing 13. For example, two fire extinguishers can be stored in the internal fire extinguisher storage section. In addition, a viewing window 2610 is provided below the fire extinguisher door 26, and the presence or absence of a fire extinguisher can be confirmed from the outside.

[0034] An electrical equipment door 30 that opens horizontally to the right by a hinge is provided on the right side of the door opening of the decorative frame 13. On the front side of the electrical equipment door 30, for example, a red indicator light 32, a transmitter 34, and a response lamp 36 are provided as electrical equipment, and a telephone jack is provided inside the housing 13 on the back side of the electrical equipment door 30. In this way, a distress reporting device is constituted by the red indicator light 32, the transmitter 34, the response lamp 36 provided on the front and back of the electrical equipment door 30, and the telephone jack on the back side of the electrical equipment door 30.

[0035] The red indicator light 32 is always on, so that the installation location of the fire hydrant device 10 can be confirmed from a distance. When a fire occurs and the transmitter 34 is pressed, a fire alarm signal is transmitted to a disaster prevention receiving panel installed in an electrical room or the like, and a fire alarm is output. The disaster prevention receiving panel that outputs a fire alarm transmits a response signal to the distress reporting device and causes the red indicator light 32 to blink by a pump start signal, and the response lamp 36 lights up, so that it can be confirmed that the fire alarm signal has been received on the disaster prevention receiving panel side.

[0036] (a2. Internal structure of the fire hydrant storage section) Next, the internal structure of the fire hydrant storage section in the fire hydrant device will be described. As shown in FIGS. 1 to 3, the interior of the housing 12 that serves as the fire hydrant storage section is divided into a valve storage section on the right side and a hose storage section on the left side.

[0037] In the valve storage section, a water supply faucet 38 is connected to the water supply pipe drawn in from the outside, and the water supply pipe branches downward and is connected to the fire hose 18 via a fire hydrant valve 40 and an automatic pressure regulating valve (not shown).

[0038] In the hose storage section, a hose storage frame 46 is provided, and the fire hose 18 drawn in from the lower side is stored in a right-handed or left-handed inner winding manner. On the back side of the fire hydrant door 14, a hose guide 22 is erected and arranged, and the fire hose 18 is drawn out from the hose storage frame 46 through the hose guide 22.

[0039] A water discharge nozzle 16 is attached to the tip of the fire hose 18 drawn out through the fire hose guide 22, and the water discharge nozzle 16 is detachably held by a nozzle holder 24 installed on the back side of the fire hydrant door 14.

[0040] The fire hydrant valve 40 is opened and closed by a fire hydrant valve opening / closing lever 20 provided in an operation box 42 installed on the back side of the fire hydrant door 14, and is opened and closed in conjunction with the opening and closing operation of the fire hydrant valve opening / closing lever 40 by a known wire link mechanism provided between an interlocking box 44 provided on the fire hydrant valve 40 and the operation box 42.

[0041] Also, a pump start interlock switch that turns on and off corresponding to the opening and closing of the fire hydrant valve 40 is built into the interlocking box 44.

[0042] When a road user conducts a fire extinguishing operation, open the fire hydrant door 14, take out the water discharge nozzle 16 from the nozzle holder 24, then operate the fire hydrant opening / closing lever 20 to the forward open position, pull out the fire hose 18, and discharge water from the water discharge nozzle 16 to conduct the fire extinguishing operation. Also, when the fire hydrant valve opening / closing lever 20 is operated to the open position, the pump start interlock switch is turned on, and a pump start signal is sent to the fire pump control panel via the disaster prevention monitoring panel to start the fire pump, so that the fire extinguishing water is continuously supplied.

[0043] [b. First nameplate and second nameplate] Next, the nameplate describing the operation method of the fire hydrant device will be explained. As shown in FIG. 1, the fire hydrant device 10 of the present invention is provided with a first nameplate 50 and a second nameplate 60.

[0044] The first nameplate 50 is the same as the nameplate 70 of the conventional fire hydrant device 10 shown in FIG. 4. A nameplate seal with the operation method printed and displayed is pasted on the stainless steel plate serving as the support base behind the operation box 42 provided with the fire hydrant valve opening / closing lever 20 arranged on the back surface of the fire hydrant door 14. The display surface of the first nameplate 50 is erected and arranged in an inclined manner such that the front side is lower and the back side is higher when viewed from the front of the opened fire hydrant door in the door open state. In this way, by directly pasting the nameplate seal on the stainless steel plate serving as the support base, the structure of the nameplate can be simplified compared to the nameplate in which the operation method of the fire hydrant device was engraved on an acrylic plate. Incidentally, the nameplate seal with the operation method printed and displayed may be pasted on an acrylic plate and fixed on the stainless steel plate serving as the support base.

[0045] On the other hand, for the second nameplate 60, a nameplate seal with the operation method printed and displayed is pasted on the back surface of the door at the rear side of the nozzle guide 18 arranged on the back surface of the fire hydrant door 14, and they are arranged in close contact. The display surface of the second display surface nameplate 60 is arranged to face substantially directly upward in the door open state.

[0046] As shown in FIG. 3, when the first nameplate 50 and the second nameplate 60 are viewed from directly above, the display surface of the first nameplate 50 is an inclined surface, making it easier to see. Also, the display surface of the second nameplate 60 is a substantially flat surface, making it easier to see.

[0047] Also, for the user of the fire hydrant device 10, when standing in front of the open fire hydrant door 14 and looking down diagonally from above, in this case as well, the display surface of the first nameplate 50 is a substantially flat surface, making it easier to see, and the display surface of the second nameplate 60 is also a substantially flat surface, making it easier to see, ensuring sufficient visibility.

[0048] Also, when pulling out the fire hose 18, the first nameplate 50 standing upright may be damaged by cracks or breaks due to contact with the fire hose 18. However, since the second nameplate 60 has a nameplate sticker attached to the back surface of the fire hydrant door 14, it is not assumed that it will be damaged by cracks or breaks to the extent of contact with the fire hose 18.

[0049] Therefore, even if the first nameplate 50 is damaged, the presence of the second nameplate 60 makes it possible to back up the display function of the damaged first nameplate 50 with the second nameplate 60, ensuring high reliability.

[0050] [d. Modification Example of the Present Invention] A modification example of the fire hydrant device according to the present invention will be described. The fire hydrant device of the present invention includes the following modifications in addition to the above-described embodiments.

[0051] (Arrangement of the First Nameplate) In the above-described embodiment, the first substrate 50 is arranged upright. However, for the first substrate 50 as well, similar to the second substrate 60, a nameplate sticker may be attached to the back surface of the fire hydrant door 14. Note that although not included in the present invention, when a nameplate sticker is attached to the back surface of the door as the first nameplate 50, the second nameplate 60 that attaches a nameplate sticker to another location on the back surface of the door may not be provided.

[0052] (Arrangement of the Second Nameplate) In the above-described embodiment, the second nameplate 60 is formed by attaching a nameplate seal to the back surface of the door behind the hose guide 22. However, the present invention is not limited to this, and it may be attached to any location on the back surface of the door. For example, it may be attached to the back surface in front of the opened fire hydrant door 14, the back surface of the right door of the operation box 42, the upper surface of the operation box 42, etc. to serve as the second nameplate.

[0053] (Protection of the nameplate seal) In addition, for each of the nameplate seals of the first nameplate and the second nameplate 60, a protective plate member such as a transparent acrylic plate may be attached on the nameplate seal so that the nameplate seal is protected from being damaged even if the fire hose 18 hits and rubs against it.

[0054] (Sealing of the second nameplate) Moreover, as the nameplate seal used for the first nameplate and the second nameplate 60, a seal made of a material having wear resistance and an anti-slip function may be used. In this case, it is not necessary to attach a protective plate member such as a transparent acrylic plate on the nameplate seal.

[0055] (Others) Furthermore, the present invention includes appropriate modifications that do not impair its object and advantages, and is not limited by the numerical values shown in the above-described embodiment.
