Description

Technical Field

[0001] The present invention relates to a fire hydrant device installed so as to be exposed in a monitor passage provided along a tunnel wall surface.

Background Art

[0002] Conventionally, fire hydrant devices have been installed in tunnels such as highways and motorways as emergency facilities in tunnels. For example, the fire hydrant device includes a fire hose with a water discharge nozzle attached to the tip and valves including a fire hydrant valve housed in a fire hydrant equipment storage section inside a housing with a forward-tilting fire hydrant door (forward-tilting door), and two fire extinguishers are housed in a fire extinguisher storage section inside a housing with a fire extinguisher door. In addition, the fire hydrant device is generally installed by cutting out the tunnel wall surface provided with a monitor passage at intervals of, for example, 50 meters in the longitudinal direction of the tunnel (Patent Document 1).

[0003] However, in a tunnel constructed by a shield method or the like, due to the structure of the tunnel body, it is difficult to cut out the tunnel wall surface and embed the fire hydrant device in terms of cost and labor. Therefore, it is required to install the fire hydrant device in a state where it is exposed in the monitor passage.

[0004] For this reason, as a structure for installing the fire hydrant device in a state where the fire hydrant device is exposed in the monitor passage without cutting out the tunnel wall surface, a wall-mounted structure has been proposed in which a gantry is installed on the tunnel wall surface and the device body of the fire hydrant device is attached and fixed to the installed gantry. The gantry of the wall-mounted structure is composed of a main support portion fixed to the wall surface and a posture holding member that holds the posture of the device body of the fire hydrant device (Patent Document 2).

[0005] However, the installation of the fire hydrant device by the wall-mounted structure has problems such as taking time and labor for attaching the fire hydrant device to the tunnel wall surface. Therefore, a so-called stationary structure has been proposed in which a gantry is installed on the road surface of the monitor passage where installation is easy, and the device body of the fire hydrant device is attached and fixed to the installed gantry.

Summary of the Invention

Problems to be Solved by the Invention

[0007] By the way, in the case of a stationary fire hydrant device, the pedestal for installing the device body of the fire hydrant device at a predetermined height on the road surface of the inspector passage is generally a formwork structure in which angle members are combined in a box shape. Exposing the angle members of the pedestal has a problem in appearance compared with the conventional wall-embedded type. Although it is conceivable to arrange a cover made of a plate member or the like around the formwork structure to hide the exposed angle members, the significance of providing an additional structure only for eliminating the poor appearance is low.

[0008] In addition, the internal space of the pedestal is used as a piping space for drawing the water supply pipe that starts from the inspector passage into the device body of the fire hydrant device. However, even so, most of the internal space of the pedestal remains as an empty space, and there is also a problem that the empty space existing in the space where the pedestal is installed is not fully utilized.

[0009] In order to solve this problem, the applicant of the present application has proposed a fire hydrant device that enables effective utilization of the installation space of the fire hydrant device by arranging a hose storage housing for storing the fire hose in the space for installing the device body at a predetermined height on the road surface of the inspector passage.

[0010] Incidentally, when a hose storage housing is arranged below the apparatus main body, the fire extinguishing hose stored in the hose storage housing is drawn out to the outside through the hose outlet of the apparatus main body located on the upper side. However, a problem remains to be solved, which is to smoothly draw out the fire extinguishing hose from the hose storage housing with a light force without causing bending (cooking).

[0011] Also, in such a configuration, valves including a fire hydrant valve are also stored in the apparatus main body arranged at a predetermined height on the road surface of the inspector passage. However, due to the arrangement of the valves, the weight of the apparatus main body increases, and the structure of the hose storage housing supporting the apparatus main body also needs to be strengthened to a robust structure, resulting in a problem of increased complexity of the structure and increased cost.

[0012] An object of the present invention is to provide a fire hydrant device that enables effective utilization of the installation space by using the space for installing the apparatus main body at a predetermined height on the road surface of the inspector passage as the hose storage space for the fire extinguishing hose, and enables the fire extinguishing hose to be smoothly drawn out from the hose storage space with a light force and the weight reduction of the apparatus main body.

Means for Solving the Problems

[0013] (Fire Hydrant Device) The present invention is a fire hydrant device installed in a state of being exposed on an inspector passage provided along a tunnel wall surface and being close to or in contact with the tunnel wall surface, wherein an apparatus main body provided with predetermined equipment excluding the fire extinguishing hose is installed at a predetermined height above the road surface of the inspector passage, a hose storage housing in which a fire extinguishing hose is stored is installed in the space between the apparatus main body and the road surface of the inspector passage, the apparatus main body is provided with a nozzle holding portion for detachably holding at least a nozzle and an opening / closing operation portion of a fire hydrant valve in the apparatus main body corresponding to the door opening of the fire hydrant door, The hose storage housing is separated into a hose storage section and a valve storage section. A hose outlet is formed on the front surface of the hose storage section, which is continuous with the door opening of the fire hydrant door. A hose storage door is provided at the hose outlet, which is opened in conjunction with the opening of the fire hydrant door. A predetermined set of valves including a fire hydrant valve is arranged in the valve storage section.

[0014] (Valve storage section) The valve storage section includes a water supply pipe that rises from the bottom and is connected to a water supply faucet arranged on the apparatus main body. A predetermined set of valves including a fire hydrant valve is arranged in a pipe that branches from the water supply pipe and is connected to a fire hose stored in the hose storage section.

[0015] (Hose outlet) The hose outlet opens horizontally on the upper side of the front surface of the hose storage section and vertically so as to be continuous with the door opening of the fire hydrant door.

[0016] (Guide frame) A guide frame for guiding the pulling out of the hose is arranged along the opening edge of the hose outlet.

[0017] (Shape of the guide frame) The guide frame has a curved portion that curves in the depth direction at a portion that is continuous with the door opening of the fire hydrant door at the hose outlet. The nozzle provided at the tip of the fire hose pulled out from the hose storage housing through the curved portion is detachably held by a nozzle holding portion within the apparatus main body.

[0018] (Fire extinguisher door and hose storage door) The fire hydrant door is opened by sliding or rotating upward from the position where the door opening is closed. When the fire hydrant door is opened, the closing hold of the hose storage door is released, and it rotates downward about the lower end to open the hose outlet.

[0019] (First hose storage structure) The hose storage section stores the fire hose wound up inside for easy pulling out. Here, the hose storage section has a hose storage shelf structure that places the upper half of the fire hose wound up inside in a vertically stacked manner from the outside to the inside around an axis perpendicular to the road surface of the inspector passage on each of the shelf plate members arranged in multiple vertical stages for easy pulling out and storage.

[0020] (Second Hose Storage Structure) The hose storage section stores the fire hose wound up in an inclined overlapping manner so that the fire hose is inclined at a predetermined angle with respect to the bottom and wound up from the bottom upward in a stacked manner for easy pulling out.

[0021] (Third Hose Storage Structure) The hose storage housing stores the fire hose by winding it vertically in order into storage compartments divided in the depth direction for easy pulling out.

[0022] (Fourth Hose Storage Structure) The hose storage housing stores the fire hose wound up outside for easy pulling out.

[0023] (Arrangement 1 of Storage Sections for Fire Hydrant Equipment, Electrical Equipment, Fire Hose, Valves, and Fire Extinguishers) The apparatus main body is separated into a fire hydrant equipment storage section where a nozzle holding section and an opening / closing operation section for the fire hydrant valve are arranged, and an electrical equipment storage section where a red indicator light, a transmitter, and a response lamp are arranged on the electrical equipment door. The hose storage housing is separated into a fire extinguisher storage section that stores at least two fire extinguishers, a hose storage section that stores the fire hose, and a valve storage section that stores predetermined valves including the fire hydrant valve.

[0024] (Arrangement 2 of Storage Sections for Fire Hydrant Equipment, Electrical Equipment, Fire Hose, Valves, and Fire Extinguishers) The apparatus main body is separated into a fire hydrant equipment storage section where a nozzle holding section and an opening / closing operation section for the fire hydrant valve are arranged, and an electrical equipment storage section where a red indicator light, a transmitter, and a response lamp are arranged on the electrical equipment door. The hose storage housing is separated into a hose storage section for storing a fire hose and a valve storage section for storing predetermined valves including a fire hydrant valve. On one side surface or both side surfaces of the apparatus main body and the hose storage housing, a fire extinguisher storage section for storing at least two fire extinguishers in two upper and lower stages is arranged.

Advantages of the Invention

[0025] (Advantages of the fire hydrant device) The present invention is a fire hydrant device installed in a state of being exposed on a monitor passage provided along a tunnel wall surface and being close to or in contact with the tunnel wall surface. An apparatus main body provided with predetermined equipment excluding a fire hose is installed at a predetermined height above the road surface of the monitor passage, and a hose storage housing in which a fire hose is stored is installed in a space between the apparatus main body and the road surface of the monitor passage. The apparatus main body has, inside the apparatus main body corresponding to the door opening of the fire hydrant door, at least a nozzle holding section for detachably holding a nozzle and an opening / closing operation section for a fire hydrant valve. The hose storage housing is separated into a hose storage section and a valve storage section. A hose outlet continuous with the door opening of the fire hydrant door is formed on the front surface of the hose storage section, and a hose storage door that is opened in conjunction with the opening of the fire hydrant door is provided at the hose outlet. Since a predetermined valve including a fire hydrant valve is arranged in the valve storage section, the hose storage housing can be arranged in the space between the apparatus main body and the road surface of the monitor passage and effectively utilized as a storage space for the fire hose. By eliminating the need for a storage space for the fire hose on the apparatus main body side, it is possible to reduce the size of the apparatus main body and the entire fire hydrant device.

[0026] In addition, the fire hose stored in the hose storage section of the hose storage housing can be smoothly pulled out with a light force without greatly curving from the hose outlet on the front surface of the hose storage section, rather than with a large curve from the hose outlet of the apparatus main body located above.

[0027] In addition, by separating the hose storage housing into a hose storage section and a valve storage section and storing predetermined valves including a fire hydrant valve in the valve storage section, it becomes unnecessary to arrange the valves on the apparatus main body, the apparatus main body is lightened, the robustness of the structure of the hose storage housing that supports the apparatus main body is suppressed, and cost reduction is made possible.

[0028] (Effect of the valve storage section) In addition, the valve storage section is provided with a water supply pipe that is erected from the lower side and connected to a water supply faucet arranged on the apparatus main body. A predetermined valve including a fire hydrant valve is arranged in a pipe that branches from the water supply pipe and is connected to a fire hose stored in the hose storage section. Therefore, for example, a portion of the hose storage housing near the side surface is separated by a partition wall to form the valve storage section. Since the height of the hose storage housing has a sufficient height of at least 800 mm, valves such as a fire hydrant valve and an automatic pressure regulating valve can be arranged vertically side by side in a relatively narrow horizontal space, and the hose storage housing can secure a hose storage section with a sufficient width even when the valve storage section is arranged. Further, by providing the valve storage section in the hose storage housing arranged at a low position on the supervisor passage, the workability can be improved because inspection, repair, replacement, etc. of the valves at a low position can be performed.

[0029] (Effect of the hose outlet) In addition, the hose outlet opens horizontally on the upper front surface of the hose storage section and opens vertically so as to be continuous with the door opening of the fire hydrant door. Therefore, even if the nozzle at the tip of the hose is detachably held inside the apparatus main body, since the hose outlet of the hose storage section is continuous with the door opening of the fire hydrant door, it is possible to pull out the fire hose following the nozzle taken out from the apparatus main body from the hose outlet of the hose storage section.

[0030] (Effect of the guide frame) In addition, since a guide frame for guiding the hose extraction is arranged along the opening edge of the hose extraction port, a guide frame made of, for example, a pipe member is arranged along the hose extraction port, so that the fire hose drawn out to the outside has reduced sliding resistance and wear is suppressed, enabling the hose to be drawn out smoothly with a light force.

[0031] (Effect of the shape of the guide frame) In addition, as for the shape of the guide frame, a curved portion extending in the depth direction is formed at a portion continuous with the door opening of the fire hydrant door at the hose extraction port. Since the nozzle provided at the tip of the fire hose drawn out from the hose storage housing passes through the curved portion and is detachably held by the nozzle holding portion in the apparatus main body, by passing the fire hose through the curved portion extending in the depth direction at the portion continuous with the door opening of the fire hydrant door of the hose extraction opening, the nozzle at the hose tip is held by the nozzle holding portion in the apparatus main body, and also enables the hose to be drawn out from the hose extraction port of the hose storage housing located on the lower side when the nozzle is taken out.

[0032] (Effect of the fire hydrant door and the hose storage door) In addition, the fire hydrant door slides or rotates upward from the position closing the door opening to open, and the hose storage door has its closing hold released when the fire hydrant door is opened and rotates downward about its lower end to open the hose extraction port. Therefore, since the fire hydrant door of the apparatus main body arranged on the hose storage housing slides or rotates upward to open, it does not prevent the opening and closing of the hose storage door of the hose storage housing arranged on the lower side. When the closing hold of the hose storage door is released by the opening of the fire hydrant door and it rotates downward to open, the hose extraction port is opened, enabling the fire hose to be drawn out.

[0033] (Effect of the first hose storage structure) In addition, the hose storage housing stores the fire hose wound inwards and is freely retractable. The hose storage housing places the upper half of the fire hose wound inwards so as to be stacked from the outside to the inside in a direction perpendicular to the road surface of the supervisor passage on each of the shelf plate members arranged in multiple stages in the vertical direction, and has a hose storage shelf structure for storing it in a freely retractable manner. Therefore, a fire hose with a predetermined length that allows overlap of the water discharge ranges with adjacent fire hydrant devices, for example, a 30 m fire hose, can be stored in a freely retractable manner. Also, when draining the fire hose after using the fire hydrant device and rewinding it into the hose storage housing, the fire hose is passed through and wound around in order from the upper side of the shelf plate members arranged in multiple stages in the vertical direction on the tunnel wall surface side corresponding to the upper half of the hose wound inwards. In this way, the upper half of the fire hose wound inwards is supported by the shelf plate members, and it becomes possible to easily rewind the fire hose into the housing without the need for special tools or the like.

[0034] (Effect of the second hose storage structure) In addition, the hose storage housing stores the fire hose wound in a state of being inclined at a predetermined angle with respect to the bottom from the bottom upwards in a stacked manner by inclined overlapping winding so as to be freely retractable. Therefore, a fire hose with a predetermined length that allows overlap of the water discharge ranges with adjacent fire hydrant devices, for example, a 30 m fire hose, can be stored in a freely retractable manner. Also, when draining the fire hose after using the fire hydrant device and rewinding it into the hose storage housing, due to the inclined overlapping winding of the fire hose, it becomes possible to easily rewind the fire hose into the housing.

[0035] (Effect of the third hose storage structure) In addition, since the hose storage housing allows the fire extinguishing hose to be wound longitudinally in order into storage compartments that are divided in the depth direction and then stored in a freely retrievable manner, it is possible to store a fire extinguishing hose with a predetermined length, for example, 30 m, that enables overlap of the water discharge ranges with adjacent fire hydrant devices, in a freely retrievable manner. Further, when draining the fire extinguishing hose after use of the fire hydrant device and winding it back into the hose storage housing, by winding the fire extinguishing hose longitudinally in order around a plurality of slit openings in the depth direction at a predetermined height inside the housing, it is possible to easily wind the fire extinguishing hose back into the housing.

[0036] (Effect of the Fourth Hose Storage Structure) In addition, since the hose storage housing allows the fire extinguishing hose to be wound externally and stored in a freely retrievable manner, that is, the fire extinguishing hose is stored in a multi-layered overlapping winding around the hose winding portion inside the housing, it is possible to store a fire extinguishing hose with a predetermined length, for example, 30 m, that enables overlap of the water discharge ranges with adjacent fire hydrant devices, in a freely retrievable manner. Further, when draining the fire extinguishing hose after use of the fire hydrant device and winding it back into the hose storage housing, since it is only necessary to perform a multi-layered overlapping winding around the hose winding portion inside the housing, it is possible to easily wind the fire extinguishing hose back into the housing.

[0037] (Effect of the Arrangement 1 of the Storage Sections for Fire Hydrant Equipment, Electrical Equipment, Fire Extinguishing Hose, Valves, and Fire Extinguishers) In addition, the apparatus main body is separated into a fire hydrant equipment storage section where a nozzle holding section and an opening / closing operation section of a fire hydrant valve are arranged, and an electrical equipment storage section where a red indicator light, a transmitter, and a response lamp are arranged on an electrical equipment door. The hose storage housing is separated into a fire extinguisher storage section that stores at least two fire extinguishers, a hose storage section that stores the fire extinguishing hose, and a valve storage section that stores predetermined valves including the fire hydrant valve. Therefore, the fire extinguishers are arranged at a low position between the apparatus main body and the road surface of the inspector passage. When a fire breaks out, road users will open the fire extinguisher door and take out one or two fire extinguishers with a chemical agent amount of 6 kg and a total weight of about 10 kg to conduct fire extinguishing activities. Since the fire extinguishers are arranged at a low position between the apparatus main body and the road surface of the inspector passage, it is easy to take out the fire extinguishers, and it is also possible to reduce damage caused by dropping of the fire extinguishers.

[0038] (Arrangement 2 Effect of Storage Parts for Fire Hydrant Equipment, Electrical Equipment, Fire Hose, Valves and Fire Extinguishers) In addition, the apparatus main body is separated into a fire hydrant equipment storage part where a nozzle holding part and an opening / closing operation part of a fire hydrant valve are arranged, and an electrical equipment storage part where a red indicator light, a transmitter and a response lamp are arranged on an electrical equipment door. The hose storage housing is separated into a hose storage part for storing a fire hose and a valve storage part for storing predetermined valves including a fire hydrant valve. On one side surface or both side surfaces of the apparatus main body and the hose storage housing, a fire extinguisher storage part for storing at least two fire extinguishers in two upper and lower stages is arranged. Therefore, since the two fire extinguishers are stored in two upper and lower stages, the lateral width of the entire fire hydrant apparatus is reduced, and accordingly, for example, it becomes possible to secure the lateral width of the hose storage part. Also, when a fire breaks out, road users will open the fire extinguisher door and take out one or two fire extinguishers with a chemical agent amount of 6 kg and a total weight of about 10 kg to carry out fire extinguishing activities. Since one fire extinguisher is arranged at a low position between the apparatus main body and the road surface of the supervisor passage, it is easy to take out the fire extinguisher, and damage due to the fall of the fire extinguisher can also be reduced. Also, since two fire extinguishers are stored separately in the upper and lower parts, road users will take out the fire extinguishers one by one, and it is possible to safely take out the fire extinguisher stored in the upper part. Furthermore, when fire extinguishers are stored in two stages on both sides of the fire hydrant apparatus, it is possible to store four fire extinguishers, enabling doubling of the fire extinguishing ability using the fire extinguishers.

Embodiment for Carrying Out the Invention

[0040] Hereinafter, embodiments of the fire hydrant device according to the present invention will be described with reference to the drawings. Note that the present invention is not limited by the following embodiments.

[0041] [Basic Concept of Embodiment] First, the basic concept of the embodiment will be described. The embodiment generally relates to a fire hydrant device that is installed so as to be exposed on a monitor passage provided along a tunnel wall surface.

[0042] Here, the "fire hydrant device" is a kind of emergency equipment installed in a tunnel such as a highway or a motorway that is a fire target area, and is provided with fire hydrant equipment such as a fire hose, electrical equipment such as a red indicator light and a transmitter, a terminal box, and a fire extinguisher, and is a concept including the fire hydrant equipment in which the fire hydrant device is installed.

[0043] In addition, the fire hydrant device of the embodiment is installed on a monitor passage provided along the tunnel wall surface so as to be close to or in contact with the tunnel wall surface, and includes a fire hydrant device installed in a state where the fire hydrant device is exposed on the monitor passage by a "wall-mounted structure" or a "standing structure".

[0044] In addition, "installed close to or in contact with the tunnel wall surface" includes installing close to the tunnel wall surface, installing a part in contact with the tunnel wall surface, or installing a part fixed to the tunnel wall surface.

[0045] In the fire hydrant device of the embodiment, a device main body provided with predetermined equipment excluding the fire hose is installed at a predetermined height above the road surface of the inspector passage, and a hose storage housing in which the fire hose is stored is provided in the space between the device main body and the road surface of the inspector passage. The basic configuration is characterized in that the space between the device main body of the fire hydrant device and the road surface of the inspector passage is effectively utilized as a storage space for the fire hose.

[0046] Here, the "device main body" means that at least a nozzle holding part for detachably holding a nozzle and an opening / closing operation part of a fire hydrant valve are arranged in the device main body corresponding to the door opening of the fire hydrant door.

[0047] Further, the "hose storage housing" is separated into a hose storage part and a valve storage part. A hose outlet continuous with the door opening of the fire hydrant door is formed on the front surface of the hose storage part, and a hose storage door that is opened in conjunction with the opening of the fire hydrant door is provided at the hose outlet. A predetermined valve including a fire hydrant valve is arranged in the valve storage part.

[0048] Therefore, by arranging the hose storage housing in the space between the device main body and the road surface of the inspector passage, it can be effectively utilized as a storage space for the fire hose, eliminating the need for a storage space for the fire hose on the device main body side, and reducing the size of the device main body and the entire fire hydrant device.

[0049] In addition, the fire hose stored in the hose storage part is not pulled out in a largely curved manner from the hose outlet of the device main body located on the upper side, but is pulled out from the hose outlet on the front surface of the hose storage part, so that it does not bend greatly and can be pulled out smoothly with a light force.

[0050] Further, by separating the hose storage housing into a hose storage part and a valve storage part and storing a predetermined valve including a fire hydrant valve in the valve storage part, there is no need to arrange the valves on the device main body, the device main body is lightened, the robustness of the structure of the hose storage housing supporting the device main body is suppressed, and cost reduction is possible.

[0051] In addition, the valve storage section includes a water supply pipe that rises from the lower side and is connected to a water supply faucet disposed on the apparatus main body. A predetermined valve including a fire hydrant valve is disposed in a pipe that branches from the water supply pipe and is connected to a fire hose stored in the hose storage section.

[0052] Therefore, for example, in the hose storage housing, a portion near the side surface is separated by a partition wall to form a valve storage section. Since the height of the hose storage housing has a sufficient height of at least 800 mm, valves such as a fire hydrant valve and an automatic pressure regulating valve can be arranged vertically in a relatively narrow lateral space, and a hose storage section with a sufficient width can be ensured even when the valve storage section is arranged. In addition, by providing a valve storage section in the hose storage housing disposed at a low position on the supervisor passage, workability can be improved because inspections, repairs, replacements, etc. of the valves at a low position can be performed.

[0053] The hose outlet of the hose storage housing opens laterally on the upper front surface of the hose storage section and opens vertically so as to be continuous with the door opening of the fire hydrant door. Therefore, even if the nozzle at the tip of the hose is detachably held in the apparatus main body, since the hose outlet of the hose storage section is continuous with the door opening of the apparatus main body, it is possible to pull out the fire hose following the nozzle taken out from the apparatus main body from the hose outlet of the hose storage section.

[0054] In addition, a guide frame for guiding the pulling out of the hose is disposed along the opening edge of the hose outlet. The guide frame is optional, but a guide frame made of, for example, a pipe member is disposed along the hose outlet. Therefore, the fire hose is pulled out to the outside while being in sliding contact with the guide frame disposed at the hose outlet, thereby reducing the sliding resistance, suppressing the wear of the fire hose, and enabling the hose to be pulled out smoothly with a light force.

[0055] In addition, as for the shape of the guide frame, a curved portion extending in the depth direction is formed at a portion continuous with the door opening of the fire hydrant door at the hose outlet, and the nozzle provided at the tip of the fire hose drawn out from the hose storage housing through the curved portion is detachably held by the nozzle holding portion in the apparatus main body.

[0056] Therefore, by passing the fire hose through the curved portion extending in the depth direction at the portion continuous with the door opening of the fire hydrant door at the hose outlet, the nozzle at the tip of the hose is held by the nozzle holding portion in the apparatus main body, and when the nozzle is taken out, it is possible to draw out the hose from the hose outlet of the hose storage housing located on the lower side.

[0057] In addition, the fire hydrant door slides upward from the position closing the door opening to open, and the hose storage door has its closing hold released when the fire hydrant door is opened, and rotates downward about the lower end as an axis to open the hose outlet.

[0058] Therefore, since the fire hydrant door of the apparatus main body arranged above the hose storage housing slides upward to open, the opening and closing of the hose storage door of the hose storage housing arranged below the apparatus main body is not hindered, and the closing hold of the hose storage door is released in conjunction with the opening of the fire hydrant door, and the hose storage door rotates downward to open, so that it is possible to draw out the fire hose from the opened hose outlet.

[0059] As a hose storage structure provided in the hose storage housing, any one of the first to fourth hose storage structures is provided.

[0060] The "first hose storage structure" is one in which the fire hose is wound inside the hose storage housing and stored so that it can be freely drawn out. A "hose storage shelf structure" is provided as a structure for winding the fire hose inside.

[0061] The "hose storage shelf structure" is a structure in which the upper half of the fire hose that is wound inward so as to be stacked vertically from the outside to the inside around an axis perpendicular to the road surface of the monitor passage within the hose storage housing is placed on each of the shelf plate members arranged in multiple stages in the vertical direction and is stored so that it can be pulled out freely.

[0062] Therefore, with the first hose storage structure, it becomes possible to freely store a fire hose with a predetermined length, for example, 30 m, which enables overlapping of the water discharge ranges with adjacent fire hydrant devices, in the hose storage housing.

[0063] Also, when the staff drains the fire hose after the fire hydrant device has been used and winds it back into the hose storage housing, by passing the fire hose through and winding it around in order from the upper side of the shelf plate members arranged in multiple stages in the vertical direction on the tunnel wall surface side corresponding to the upper half of the inwardly wound hose, the upper half of the inwardly wound fire hose is supported by the shelf plate members, and it becomes possible to easily wind the fire hose back into the housing without the need for special tools or the like.

[0064] The "second hose storage structure" is one in which inside the hose storage housing, the fire hose is stored so that it can be pulled out freely by being wound around in an inclined overlapping manner so as to be stacked upward from the bottom while being inclined at a predetermined angle with respect to the bottom.

[0065] Therefore, with the second hose storage structure, it becomes possible to freely store a fire hose with a predetermined length, for example, 30 m, which enables overlapping of the water discharge ranges with adjacent fire hydrant devices, in the hose storage housing. Also, when the staff drains the fire hose after the fire hydrant device has been used and winds it back into the hose storage housing, it becomes possible to easily wind the fire hose back into the housing by the inclined overlapping winding of the fire hose.

[0066] The "third hose storage structure" is one in which inside the hose storage housing, the fire hose is wound in sequence in a vertical direction into storage compartments divided in the depth direction of the fire hose and is stored so that it can be pulled out freely.

[0067] Therefore, with the third hose storage structure, a fire hose with a predetermined length that enables overlap of the water discharge ranges with adjacent fire hydrant devices, for example, a 30 m fire hose, can be freely drawn out and stored in the hose storage housing. Further, when an operator drains the fire hose and winds it back into the hose storage housing after the fire hydrant device has been used, the fire hose can be easily wound back into the housing by winding it vertically in order around a plurality of slit openings in the depth direction at a predetermined height within the housing.

[0068] The "fourth hose storage structure" is one in which the fire hose is stored in the hose storage housing by being wound externally and can be freely drawn out. For example, the fire hose is stored in a hose winding portion within the housing by being wound back and forth in a plurality of layers.

[0069] Therefore, with the fourth hose storage structure, a fire hose with a predetermined length that enables overlap of the water discharge ranges with adjacent fire hydrant devices, for example, a 30 m fire hose, can be freely drawn out and stored. Further, when an operator drains the fire hose and winds it back into the hose storage housing after the fire hydrant device has been used, since it is only necessary to wind the fire hose back and forth in a plurality of layers around the hose winding portion within the housing, the fire hose can be easily wound back into the housing.

[0070] Further, in the fire hydrant device of the embodiment, as the "first arrangement (Arrangement 1) of each storage portion" of the fire hydrant equipment, electrical equipment, fire hose, valves, and fire extinguishers, the apparatus main body is separated into a fire hydrant equipment storage portion in which a nozzle holding portion and an opening / closing operation portion of the fire hydrant valve are arranged, and an electrical equipment storage portion in which a red indicator light, a transmitter, and a response lamp are arranged on the electrical equipment door. The hose storage housing is separated into a fire extinguisher storage portion that stores at least two fire extinguishers, a hose storage portion that stores the fire hose, and a valve storage portion that stores predetermined valves including the fire hydrant valve.

[0071] Therefore, the fire extinguisher is arranged at a low position between the device main body and the road surface of the supervisor passage. When a fire breaks out, road users will open the fire extinguisher door and take out one or two fire extinguishers with a total weight of about 10 kg to carry out fire extinguishing activities. Since the fire extinguisher is arranged at a low position between the device main body and the road surface of the supervisor passage, it is easy to take out the fire extinguisher from the fire extinguisher storage part, and the damage caused by dropping from the fire extinguisher storage part can also be reduced.

[0072] In addition, for the "second arrangement (Arrangement 2) of each storage part" of the fire hydrant device of the embodiment, the device main body is separated into a fire hydrant device storage part where a nozzle holding part and an opening / closing operation part of a fire hydrant valve are arranged, and an electrical equipment storage part where a red indicator light, a transmitter, and a response lamp are arranged on the electrical equipment door. The hose storage housing is separated into a hose storage part for storing a fire hose and a valve storage part for storing predetermined valves including a fire hydrant valve. The fire extinguisher storage part for storing at least two fire extinguishers is arranged in two upper and lower stages on one side surface or both side surfaces of the device main body and the hose storage housing.

[0073] For this reason, since two fire extinguishers are stored in two upper and lower stages, the width of the entire fire hydrant device is reduced, and accordingly, for example, it is possible to secure the width of the hose storage part. Also, when a fire breaks out, road users will open the fire extinguisher door and take out one or two fire extinguishers with a total weight of about 10 kg to carry out fire extinguishing activities. Since one fire extinguisher is arranged at a low position between the device main body and the road surface of the supervisor passage, it is easy to take out the fire extinguisher from the fire extinguisher storage part, and the damage caused by dropping from the fire extinguisher storage part can also be reduced. Also, since two fire extinguishers are stored separately in the vertical direction, the fire extinguishers will be taken out one by one, and it is possible to safely take out the fire extinguisher stored on the upper side. Furthermore, when fire extinguishers are stored in two stages on both sides of the fire hydrant device, it is possible to store four fire extinguishers, enabling a doubling of the fire extinguishing ability using the fire extinguishers.

[0074] Furthermore, the terms "provide", "arrange", "install", and "store" may each include other terms that can be used as alternatives in the expression, and in addition, concepts that may include terms that can be substituted from the meaning of the terms, such as "attach", "attach and fix", "mount", etc.

[0075] Hereinafter, specific embodiments will be described. In the specific embodiments shown below, a "stationary structure" in which the fire hydrant device is exposed and arranged on the road surface of the inspector passage is adopted, the "device main body" is composed of a "first housing and a second housing", the "hose storage housing" is the "third housing", the "third housing" is separated into a "hose storage part" and a "valve storage part", and the "fire hydrant device with the first to fourth hose storage structures of the third housing" is the "first to fourth embodiments of the fire hydrant device". In addition, as the arrangement of each storage part of the fire hydrant device different from the first to fourth embodiments of the fire hydrant device, the "first and second arrangements of each storage part of the fire hydrant device" will be described as the "fifth and sixth embodiments of the fire hydrant device".

[0077] [a. Structure of the fire hydrant device common to the first to fourth embodiments] First, the structure of the fire hydrant device common to the first to fourth embodiments will be described. In this description, reference is made to FIG. 1 showing the fire hydrant device common to the first to fourth embodiments installed on the road surface of the supervisor passage from the front (front side), and FIG. 2 showing the housing structure of the fire hydrant device of FIG. 1 in an assembled and disassembled state.

[0078] Here, in the description of FIGS. 1 and 2, the X - Y - Z directions are perpendicular to each other. Specifically, when looking at the front of the fire hydrant device 10 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 rear side. This is the same in FIGS. 3 to 32 which are the embodiments of the present invention.

[0079] As shown in FIG. 1, the fire hydrant device 10 is installed on a pedestal 32 installed on the road surface of the supervisor passage 34. The housing of the fire hydrant device 10 is divided into a first housing 11a and a second housing 11b that constitute the device body, and a third housing 11c that constitutes the hose storage housing, as shown in FIG. 2.

[0080] Here, the interior of the first housing 11a becomes a fire hydrant equipment storage section 40 that stores fire hydrant equipment excluding the fire hose and valves. Also, in this embodiment, since there is a space above the fire hydrant equipment storage section 40, this portion becomes a spare parts storage section 47 partitioned into two locations on the left and right.

[0081] The interior of the second housing 11b is partitioned into left and right by a partition wall 45. The right side becomes an electrical equipment storage section 45a, and the left side becomes a fire extinguisher storage section 45b.

[0082] The interior of the third housing 11c is partitioned into left and right by a partition wall 77 disposed at a position close to the right side surface. The narrow region on the right side becomes a valve storage section 46 that stores predetermined valves including a fire hydrant valve, and the wide region on the left side becomes a hose storage section 48 that stores a fire hose.

[0083] Also, a hose extraction opening 42a is formed on the left side of the bottom surface (lower left surface) of the first housing 11a corresponding to the fire hydrant equipment storage section 40, and a hose extraction opening 42b is formed on the upper surface of the third housing 11c corresponding to the hose storage section 48 disposed below the first housing 11a.

[0084] Also, a pipe through hole 43a is formed on the right side of the bottom surface of the first housing 11a, and pipe through holes 43b and 43c that face the pipe through hole 43a are formed on the upper surface and the bottom surface of the third housing 11c corresponding to the valve storage section 46 disposed below the first housing 11a.

[0085] Also, a wire passing opening 44a is formed on the upper side of the left side surface of the first housing 11a, and a wire passing opening 44b that faces the wire passing opening 44a is formed on the upper side of the right side surface of the second housing 11b disposed on the left side of the first housing 11a.

[0086] As shown in FIG. 1, a decorative frame 12a is attached to the front surface of the first housing 11a. In the door opening of the decorative frame 12a, a fire hydrant door 14 that slides upward and opens is disposed when the lock is released by the operation of a door opening / closing handle 1410.

[0087] As will be described later, the fire hydrant equipment storage section 40 inside the first housing 11a stores fire hydrant equipment including a water discharge nozzle to which a fire hose is connected, an opening / closing operation lever for a fire hydrant valve, a water supply faucet, and a pump starting device.

[0088] A decorative frame 12b is attached to the front surface of the second housing 11b. An electrical equipment door 18 that opens horizontally to the right by a hinge 18a is arranged at the door opening on the right side of the decorative frame 12b, and an auxiliary door 20 that opens horizontally to the left by a hinge 20a to enable access to the internal terminal boxes 25a, 25b is arranged on the left side thereof.

[0089] In the embodiment, since the auxiliary door 20 is arranged, the electrical equipment storage section 45a is enlarged compared to the conventional case, so that the terminal boxes 25a, 25b that were conventionally arranged on the inner rear surface of the fire extinguisher storage section can be arranged on the inner rear surface of the auxiliary door 20.

[0090] On the electrical equipment door 18, as electrical equipment, for example, a red indicator lamp 22, a transmitter 24, and a response lamp 28 are arranged, and a telephone jack 26 is arranged on the inner side of the door. The red indicator lamp 22 is always lit so that the installation location of the fire hydrant device 10 can be confirmed from a distance. Further, when the transmitter 24 is pressed, for example, when a fire or the like occurs and the switch is turned on, a transmission signal is transmitted, and a fire alarm is output from a disaster prevention receiving panel installed in an electrical room or the like that receives this. The fire hydrant device 10 that receives a response signal from the disaster prevention receiving panel lights up the response lamp 28.

[0091] Also, when the fire hydrant valve is opened by operating the fire hydrant valve opening / closing lever, a pump starting signal is transmitted to the disaster prevention receiving panel. The disaster prevention receiving panel controls the starting of the fire pump equipment and simultaneously blinks all the red indicator lamps 22 provided in all the fire hydrant devices 10 to notify the occurrence of a fire.

[0092] On the rear surface inside the second housing 11b opposite to the auxiliary door 20, a high-voltage terminal box 25a and a low-voltage terminal box 25b are arranged side by side, for example, in the vertical direction. The high-voltage terminal box 25a uses the built-in terminal block to connect the power cable for strong electricity drawn from outside the fire hydrant device 10 and the red indicator lamp 22. The low-voltage terminal box 25b uses the built-in terminal block to connect the signal cable for weak electricity drawn from outside the fire hydrant device 10, the transmitter 24, the response lamp 28, and the telephone jack 26.

[0093] Also, in the left door opening of the decorative frame 12b attached to the second housing 11b, when the lock is released by operating the door opening / closing handle 1610, a fire extinguisher door 16 that opens horizontally to the left by the hinge 16a is arranged. In the fire extinguisher storage part 45b inside the door, for example, two fire extinguishers are stored. In addition, a viewing window 1612 is provided on the fire extinguisher door 16, so that the presence or absence of a fire extinguisher can be confirmed from the outside.

[0094] The third housing 11c has a hose storage part 48 and a valve storage part 46 formed inside the housing. It also functions as a mount for attaching and fixing the first housing 11a and the second housing 11b, which are connected and fixed in the left-right direction, to the tunnel wall surface at a predetermined height above the road surface of the monitor passage 34 in contact with or close to it.

[0095] In the valve storage part 46 formed on the right side of the third housing 11c, when the lock is released by operating the door opening / closing handle 1610, an inspection door 17 that opens horizontally to the right is arranged. Inside the door, predetermined valves including a fire hydrant valve and an automatic pressure regulating valve are stored.

[0096] On the front surface of the third housing 11c corresponding to the hose storage part, a decorative panel 12c is attached. Horizontally long hose storage doors 30 are arranged to open downward with the hinges 30a on both lower ends as axes in the horizontal direction at the upper part of the decorative panel 12c. The hose storage door 30 has a sub-door part 3012 integrally formed near the center of the upper part of the horizontally long door body 3010 toward the first housing 11a side. At the upper tip of the sub-door part 3012, a door locking part 3014 is formed, which is located inside the fire extinguisher door 14 and holds the hose storage door 30 in the closed position.

[0097] On the front surface of the third housing 11c on the back side of the hose storage door 30 that is kept closed, a hose outlet is formed as a door opening. The size of the hose outlet where the hose storage door 30 is arranged is arbitrary, but it has a width and a length sufficient to draw out the hose in the left - right direction. In particular, regarding the width, it is a horizontally long hose outlet that extends across the entire width of the hose storage section.

[0098] When a road user operates the door opening and closing handle 1410 of the fire hydrant door 14 provided on the first housing 11a, the fire hydrant door 14 slides upward to open. Along with the opening of the fire hydrant door 14, the closing and holding of the hose storage door 30 by the door locking portion 3014 is released, and it rotates downward and opens. As a result, the hose outlet that was closed by the hose storage door 30 opens, and the road user can take out the water discharge nozzle held inside the first housing 11a where the fire hydrant door 14 is opened, and draw out the fire hose from the hose outlet where the hose storage door 30 is opened. Note that the downward rotation when the closing and holding of the hose storage door 30 is released is preferably configured to automatically rotate by its own weight or the biasing force of a spring or the like, but it may also be due to the operation of the handle 3016.

[0099] Also, the decorative panel 12c arranged on the front surface of the hose storage section 48 can be opened to an inclined position where the upper part rotates forward with both lower ends as hinges (the door holding in the inclined open position is held by a stay or a chain). When the attendant performs the rewinding operation of draining the fire hose and storing it in the hose storage section after the fire hydrant device is used, the decorative panel 12c is opened to an inclined position with the upper side open, so that the rewinding operation of the fire hose can be easily performed.

[0100] [b. Installation of the fire hydrant device] Next, the installation of the fire hydrant device with respect to the supervisor passage will be described. In this description, in addition to FIGS. 1 and 2, refer to FIG. 3 which shows the fire hydrant device of FIG. 1 from the left side.

[0101] As shown in Fig. 3, a road 38 is constructed in the longitudinal direction of the tunnel (the left - right direction in Fig. 1) at the lower part of a cylindrical (circular cross - section) tunnel body constructed by the shield method. A supervisor passage 34 of a predetermined height with respect to the road 38 is constructed on the lower side of the tunnel wall surface 35 along the road 38. The inside of the supervisor passage 34 serves as a duct, and a main water supply pipe 37 and cables are laid inside. A water supply pipe 36 branched from the main water supply pipe 37 is taken out on the road surface of the supervisor passage 34. A lead - in pipe is connected to the water supply pipe 36, and the lead - in pipe passes vertically through the valve storage part 46 of the third housing 11c (see Fig. 2) and is led into the fire hydrant equipment storage part 40 (see Fig. 2) inside the first housing 11a located above the third housing 11c.

[0102] Since it is difficult to cut out a box for installing the fire hydrant device 10 in the tunnel wall surface 35 constructed by the shield method, the fire hydrant device 10 is installed by installing the third housing 11c on the pedestal 32 close to the tunnel wall surface 35 on the road surface of the supervisor passage 34, and attaching and fixing the connected first housing 11a and second housing 11b on the third housing 11c, so that the first housing 11a and the second housing 11b are installed at a predetermined height on the road surface of the supervisor passage 34. Also, the upper parts of the first housing 11a and the second housing 11b are fixed to the tunnel wall surface 35 by the housing support member 41 so as not to fall forward.

[0103] Here, the height of the third housing 11c is set so that the height from the road surface of the supervisor passage 34 to all the operation targets including the transmitter 24 and the water discharge nozzle arranged in the fire hydrant device 10 falls within the legally defined proper operation range. When the road surface of the supervisor passage 34 is regarded as the standing surface of road users, as is well - known, the legally defined proper operation range has a lower limit height H1 of 800 mm and an upper limit height H2 of 1500 mm from the road surface, and the height width Hw of the proper operation range is 700 mm.

[0104] In this embodiment, the height from the road surface of the supervisor passage 34 to the bottom surfaces of the first housing 11a and the second housing 11b (= the height of the pedestal 32 + the height of the third housing 11c) is set so that all of the operation targets arranged in the first housing 11a and the second housing 11b are within the proper operation range. Although this height can be arbitrary as long as all of the operation targets are within the proper operation range, for example, by setting it to 800 mm, which is the same as the lower limit height H1 of the proper operation range, all of the operation targets arranged in the first housing 11a and the second housing 11b are arranged at positions not lower than the lower limit height regardless of their positions.

[0105] [c. Thinning of the fire hydrant device] Next, the thinning of the fire hydrant device will be described. As shown in FIG. 3, in order to reduce the restriction on the passage width of the supervisor passage 34 due to the protrusion (protrusion) of the fire hydrant device 10 installed on the road surface of the supervisor passage 34 from the tunnel wall surface 35, the fire hydrant device 10 is thinned as much as possible.

[0106] The thinning of the fire hydrant device 10 will be optimized according to the equipment housed inside the fire hydrant device 10. In the embodiment, among the equipment housed inside the fire hydrant device 10, the one with the largest size in the front-rear direction is the fire extinguisher housed in the second housing 11b. Since the depth width (thickness in the front-rear direction) of the fire hydrant device 10 can be thinned to a size capable of housing the fire extinguisher, the depth width of the fire hydrant device 10 is set to a predetermined depth width corresponding to the outer diameter of the fire extinguisher housed in the second housing 11b.

[0107] The fire extinguisher stored in the second housing 11b of the fire hydrant device 10 is, for example, a 20-type fire extinguisher with a chemical agent amount of 6 kg and a total weight of about 10 kg. Since the outer diameter of the 20-type fire extinguisher is about 160 to 180 mm, when a gap is secured so that the stored fire extinguisher does not contact the second housing 11b, the minimum depth width of the fire hydrant device 10 is set to a predetermined width within a range of, for example, about 200 mm to 250 mm, for example, 250 mm or less. The depth widths of the first housing 11a, the second housing 11b, and the third housing 11c are all set to a predetermined width of 250 mm or less. On the other hand, since the depth width of a conventional fire hydrant device that is installed by cutting out the wall surface of the tunnel structure and embedding it is 300 mm or more, the depth width of the fire hydrant device 10 of the embodiment is reduced compared to the conventional fire hydrant device, and the fire hydrant device 10 can be made thinner.

[0108] [d. Reduction in height of fire hydrant device] Next, the reduction in height of the fire hydrant device will be described. As shown in FIG. 3, the height width (vertical width) of the first housing 11a and the second housing 11b whose housing bottom surface is installed at a height H1 on the road surface of the inspector passage 34 by the gantry 32 and the third housing 11c is set to the minimum height width necessary to accommodate the device with the maximum height among the devices stored in the first housing 11a and the second housing 11b. In the embodiment, since there is no need to store the fire hose in the first housing 11a, the device with the maximum height is the fire extinguisher stored in the second housing 11b as in the case of the above-described thinning, and the height width (vertical width) of the second housing 11b is set to the minimum height width in which the fire extinguisher can be stored.

[0109] Similar to the case of the above-described thinning, when storing a 20-type fire extinguisher with a chemical agent amount of 6 kg and a total weight of about 19 kg in the second housing 11b, since the height of the 20-type fire extinguisher is about 600 mm, when a gap is secured so that the stored fire extinguisher does not contact the inner upper surface of the second housing 11b, the height of the second housing 11b is set to, for example, 700 mm, and the height width of the first housing 11a and the second housing 11b can be set to a height equal to or less than the height width Hw (= 700 mm) of the proper operation range, and the height from the road surface of the monitor passage 34 to the upper surfaces of the first housing 11a and the second housing 11b can be made equal to or less than the upper limit height H2 (= 1500 mm) of the proper operation range. Thereby, all of the operation targets arranged in the first housing 11a and the second housing 11b will be arranged at positions equal to or less than the upper limit height regardless of their positions.

[0110] [e. Fire hydrant device of the first embodiment] Next, the fire hydrant device of the first embodiment will be described. In this description, refer to FIG. 4 showing the hose storage structure provided in the first embodiment of the fire hydrant device with the front surfaces of the first housing and the third housing opened and shown from the front, FIG. 5 showing the fire hydrant device from the front excluding the guide frame that partitions the hose outlet from the third housing of FIG. 4, and FIG. 6 showing the hose storage shelf structure of FIG. 5 taken out. Note that FIG. 6(A) shows the hose storage shelf structure from the front, and FIG. 6(B) shows it from the side.

[0111] (e1. Internal structure of the first housing) First, the internal structure of the first housing 11a will be described. Inside the first housing 11a, a fire hydrant equipment storage section 40 and a spare parts storage section 47 are arranged. In the fire hydrant equipment storage section 40 that occupies about two-thirds of the lower height region of the first housing 11a, predetermined fire hydrant equipment including a water supply faucet 50, a drain nozzle 66, an operation box 68, a fire hydrant valve opening / closing lever 70, and a pump starting device 76 is stored.

[0112] Specifically, a grid-like frame 64 is arranged on the front side of the center of the fire hydrant equipment storage section 40. A nozzle holder 67 is attached to the frame 64, and a water discharge nozzle 66 attached to the tip of the fire hose 62 stored in the hose storage section 48 of the third housing 11c is detachably held by the nozzle holder 67.

[0113] Also, on the right side of the frame 64, an operation box 68 having a fire hydrant valve opening and closing lever 70 for remotely operating the fire hydrant valve 56 arranged in the valve storage section 46 of the third housing 11c is arranged. Note that the remote control of the fire hydrant valve 56 will be described in the internal structure of the valve storage section 46 described later.

[0114] The lead-in pipe 3610 that rises through the valve storage section 46 of the third housing 11c is led into the right side of the fire hydrant equipment storage section 40, and a water supply faucet 50 is connected to the tip of the pipe. The water supply faucet 50 is used when the fire brigade connects a fire hose and discharges water. Also, a pump starting device 76 is arranged in the housing on the right side of the water supply faucet 50. When a fireman connects a hose to the water supply faucet 50 and extinguishes a fire, the pump starting device 76 turns on the switch by a pushing operation and transmits a pump starting signal to the disaster prevention receiving panel to start the fire pump equipment.

[0115] On the upper side of the first housing 11a, spare parts storage sections 47 are formed in two places, left and right. Tools, test jigs, etc. necessary for the maintenance and management of the fire hydrant device 10 are stored in the spare parts storage section 47 as needed, and tools such as helmets and gloves used by the staff on site are also stored. Note that the spare parts storage section 47 does not necessarily have to be provided and may be left as an empty area in the fire hydrant equipment storage section 40.

[0116] (e2. Internal Structure of the Second Housing) Subsequently, the internal structure of the second housing 11b will be described.

[0117] As shown in Fig. 2, the interior of the second housing 11b is divided by a partition wall 45 into an electrical equipment storage section 45a and a fire extinguisher storage section 45b. As described above, a red indicator lamp 22, a transmitter 24, and a response lamp 28 are arranged on the electrical equipment door 18 provided at the door opening on the front surface of the electrical equipment storage section 45a. A telephone jack 26 is arranged on the back surface of the electrical equipment door 18. Terminal boxes 25a and 25b are arranged on the back surface of the housing, which is the interior of the auxiliary door 20, as shown in Fig. 1. Also, two fire extinguishers 19 are stored in the fire extinguisher storage section 45b.

[0118] (e3. Structure of the valve storage section of the third housing) Next, the internal structure of the valve storage section 46 of the third housing 11c will be described.

[0119] As shown in Fig. 4, in the valve storage section 46 formed by being partitioned by the partition wall 77 on the right side of the third housing 11c, a fire hydrant valve 56 and a pressure regulating valve 58 are sequentially connected in the middle of a pipe 3612 that branches downward from the upper side of a lead-in pipe 3610 that penetrates vertically.

[0120] The fire hydrant valve 56 is provided with an interlocking box 72, and a wire is connected between the interlocking box 72 and an operation box 68 arranged in the fire hydrant equipment storage section 40 of the first housing 11a. A known wire link mechanism is provided to transmit the rotation accompanying the opening and closing operation of the fire hydrant valve opening and closing lever 70 of the operation box 68 to the interlocking box 72 via the wire to open and close the fire hydrant valve 56.

[0121] The automatic pressure regulating valve 58 adjusts the pressure of the fire extinguishing water supplied to the fire hose 62 so as to maintain a predetermined pressure. The pipe 3614 following the automatic pressure regulating valve 58 bends leftward at the lower end and is connected to the fire hose 62 stored in the hose storage section 48 of the third housing 11c by a hose joint 60. The type and structure of the hose joint 60 are arbitrary. For example, by using a known Machino type joint, the fire hose 62 is detachably connected to the pipe 3614.

[0122] Inside the operation box 68, a pump start interlocking device 74 is provided. The pump start interlocking device 74 turns on when the fire hydrant valve opening / closing lever 70 is operated to the open position, and sends a pump start signal to the disaster prevention receiving panel to start the fire pump facility.

[0123] In this way, in the valve storage section 46, the lead-in pipe 3610, pipes 3612 and 3614, the fire hydrant valve 56, and the automatic pressure regulating valve 58 are arranged vertically. The vertical width is 800 mm, which is a sufficient height and does not require a large horizontal width. Therefore, the hose storage section 48 formed in the same third housing 11c is not greatly restricted in horizontal width, and a sufficient length of horizontal width can be ensured. In addition, since the water supply pipe 36 from the duct in the monitor passage 34 is directly raised from the bottom of the third housing 11c, the water supply pipe 36 is not exposed outside the fire hydrant device 10, improving the appearance when the fire hydrant device 10 is installed.

[0124] (e4. Hose storage structure of the third housing) Next, the hose storage structure of the third housing provided in the fire hydrant device of the first embodiment will be described. As shown in FIG. 5, in the hose storage structure provided in the first embodiment, hose storage shelf structures 78 are arranged at three locations on the rear side (back side) of the hose storage section 48. As shown in FIG. 6, the hose storage shelf structure 78 has a structure in which shelf plate members 80 are arranged in multiple stages at hose passing positions that are the upper half of the hose inner winding in the vertical direction of the back plate 82 arranged inside the rear surface of the hose storage section 48.

[0125] Here, the shelf plate member 80 includes an inclined plate portion that bends obliquely upward from the front from the lower side of the vertical plate portion fixed to the back plate 82 in the vertical direction, and the inclined plate portion has a predetermined inclination angle θ with respect to the horizontal direction. The inclination angle θ of the inclined plate portion is arbitrary, but as shown in the uppermost shelf plate member 80, when the fire hose 62 is placed through the shelf plate member 80, it is an angle at which it does not easily slip out from the inclined plate portion. For example, it is a predetermined angle of around 10°. Note that the inclination angle θ may be 0°. In this case, the tip of the horizontally arranged inclined plate portion is curved upward to form a retaining portion.

[0126] In addition, the vertical arrangement interval of the shelf board members 80 is an interval through which one fire hose 62 can pass (an interval with a width corresponding to the outer diameter of the hose). Also, as shown in FIG. 5, the number of steps of the shelf board members 80 corresponds to the maximum number of turns when a 30-meter fire hose 62 is wound inside the hose storage part 48. Since the present embodiment has 6 turns, 6 shelf board members 80 are arranged in 6 steps. Further, the shelf board members 80 are arranged corresponding to the upper half of the fire hose 62 to be wound inside, and no shelf board members 80 are provided for the lower half of the fire hose 62 to be wound inside, and it is wound inside in a free state. Note that shelf board members 80 may be provided for the lower half of the fire hose 62 to be wound inside.

[0127] Therefore, as shown in FIG. 5, in the hose storage part 48, the fire hose 62 connected to the pipe 3614 of the valve storage part 46 by the hose joint 60 and having its tip taken out to the first housing 11a side is passed through the shelf board members 80 arranged in multiple stages on the upper side of the hose storage shelf structure 78 provided in three parts in order from the top, and wound inside, for example, clockwise from the outside to the inside. In this way, the upper half of the fire hose 62 wound inside by the shelf board members 80 is supported and stored.

[0128] Here, the diameters of the left and right semi-circular parts at the innermost circumference of the wound fire hose 62 are not less than a predetermined bending allowable diameter at which the used shape-retaining hose does not bend. The bending allowable diameter of the fire hose 62 varies depending on the manufacturer, but is, for example, about 340 mm. Also, the lateral width (width in the left-right direction) of the hose storage part 48 is, for example, about 2000 mm, and the height width (width in the up-down direction) is about 800 mm. Therefore, the hose length per turn averages about 5 m, and the 30-m fire hose 62 can be stored by winding it inside about 6 turns. For this reason, the fire hose 62 wound inside the box-shaped area 78 is wound so as to be in a single row in the front-rear direction (see FIG. 10).

[0129] (e5. Hose drawing structure of the third housing) Next, a hose drawing structure provided in the hose storage portion 48 of the third housing 11c will be described. In this description, in addition to FIG. 4, reference will be made to FIG. 7 showing the guide frame of FIG. 4 taken out. Note that FIG. 7(A) shows the guide frame from the front, FIG. 7(B) shows the plan view, and FIG. 7(C) shows the side view.

[0130] Corresponding to the hose outlet closed by the hose storage door 30 of the third housing 11c shown in FIG. 1, as shown in FIG. 4, a guide frame 84 shown in FIG. 7(A) having a shape along the opening edge of the hose outlet is arranged. The guide frame 84 is attached and fixed to the back side of the door opening formed in the decorative panel 12c.

[0131] The guide frame 84 is configured by connecting pipe members, and a hose drawing curved portion 88 is formed at the upper center of the horizontally long hose outlet 86. As shown in FIGS. 7(B) and 7(C), the hose drawing curved portion 88 rises to a predetermined height in the vertical direction and then curves in the depth direction. As shown in FIG. 4, with the tip side of the fire hose 62 stored in the hose storage portion 48 passing through the hose drawing curved portion 88 facing upward, the water discharge nozzle 66 attached to the hose tip can be detachably held by the nozzle holder 67 in the first housing 11a.

[0132] (e6. Opening and closing structure of fire hydrant door and hose storage door) Next, the opening and closing structure of the fire hydrant door 14 of the first housing 11a and the hose storage door 30 of the third housing 11c will be described. In this description, reference will be made to FIG. 8 showing the open state of the fire hydrant door and the hose storage door from the front, FIG. 9 showing the opening and closing of the fire hydrant door and the hose storage door from the side, FIG. 10 showing the drawing out of the fire hose in a cross section from the side with the fire hydrant door and the hose storage door open, and FIG. 11 showing the drawing out of the fire hose from the plan view. Note that FIG. 9(A) shows the closed state of the fire hydrant door and the hose storage door, and FIG. 9(B) shows the open state.

[0133] As shown in Fig. 9(A), the fire hydrant door 14 is arranged to be slidable vertically on the front side of the first housing 11a. For example, both sides of the fire hydrant door 14 are housed in guide grooves arranged in the height direction of the side surfaces inside the first housing 11a, and rollers are arranged at the door side ends or in the guide grooves.

[0134] As a mechanism for raising and lowering the fire hydrant door 14, for example, a gas spring 92 is arranged. The gas spring 92 has a piston slidably provided in a cylinder 9210, and a rod 9212 connected to the piston is taken out upward. The cylinder 9210 is fixed to the bottom of the first housing 11a at the lower end and stands upright, and the tip of the rod 9212 drawn upward is fixed to the upper end side of the fire hydrant door 14 by a door support portion 1412.

[0135] As shown in Fig. 9(A), the fire hydrant door 14 is held in the closed position by a door opening / closing handle 1410. In this state, the gas spring 92 biases the fire hydrant door 14 upward via the rod 9212 due to the compression of the inert gas by the piston provided in the cylinder 9210.

[0136] On the front side of the third housing 11c that serves as the hose storage portion 48, a hose storage door 30 is arranged to be openable and closable in the vertical direction by a hinge 30a at the lower end. A door locking portion 3014 extending above the door is located inside the lower end of the fire hydrant door 14, and the hose storage door 30 is held in the closed position.

[0137] In this state, when the closing hold of the fire hydrant door 14 is released by operating the door handle 1410, as shown in Fig. 9(B), the fire hydrant door 14 is pushed up by the rod 9212 of the gas spring 92, and the front surface of the first housing 11a is opened as shown in Fig. 8.

[0138] Also, with the opening of the fire hydrant door 14, the closing hold of the hose storage door 30 by the door locking portion 3014 of the hose storage door 30 is released. As shown in Fig. 9(B), the hose storage door 30 opens downward about the hinge 30a, and the hose outlet 86 partitioned by the guide frame 84 is exposed as shown in Fig. 8.

[0139] Therefore, when a road user takes out the water discharge nozzle 66 from the nozzle holder 67 in the first housing 11a, the portion of the fire hose 62 from the first housing 11a to the third housing 11c is pulled forward. Subsequently, as shown in FIG. 10, the fire hose 62 stored in the hose storage portion 48 is pulled out through the horizontally long opening portion of the hose outlet 86 partitioned by the guide frame 84. In this case, since the fire hose 62 is directly pulled out from the hose storage portion 48 of the third housing 11c without passing through the first housing 11a, the degree of curvature of the fire hose 62 is suppressed, and it is possible to smoothly pull it out with a light force from the hose outlet 86 partitioned by the guide frame 84.

[0140] Also, when a road user takes the water discharge nozzle 66 and pulls out the fire hose 62, the fire hydrant valve 56 is opened by pulling down the fire hydrant valve opening / closing lever 70 in the first housing 11a shown in FIG. 4 downward, and the fire hose 62 is pulled out toward the fire occurrence location while discharging the fire extinguishing water from the water discharge nozzle 66.

[0141] Such pulling out of the fire hose 62 from the hose storage portion 48 of the third housing 11c, as shown in the plan view of FIG. 11, in addition to pulling out the fire hose 62 in the forward direction, pulling out of the fire hose 6210 in the left direction and pulling out of the fire hose 6212 in the right direction are performed according to the fire occurrence location. In this case, since the hose outlet 86 has a sufficiently long horizontal width close to the horizontal width of the hose storage portion 48, smooth pulling out without bending is possible even when pulling out the hose in the left direction or the right direction.

[0142] (e7. Hose rewinding operation) Next, the operation of rewinding the fire hose after using the fire hydrant will be described. The operation of rewinding the fire hose 62 is performed as a restoration operation after a road user in the tunnel opens the fire hydrant door 14, takes out the water discharge nozzle 66, pulls out the fire hose 62, and finishes the fire extinguishing activity. In addition, the operation of winding the hose after the assembly of the fire hydrant device 10 is completed in the manufacturing process at the factory is the same operation.

[0143] After the fire hydrant device 10 is used, for the hose rewinding operation, first, open the inspection door 17 on the right side of the third housing 11c shown in FIG. 1 to expose the valve storage part 46 as shown in FIG. 4. Also, release the closure of the decorative panel 12c of the third housing 11c by screwing or the like, and set it to the forward tilt open position where the upper part is opened with the hinges on both lower ends as the axis. The forward tilt open position is held by a stay or a chain.

[0144] Subsequently, as shown in FIG. 10, remove the water discharge nozzle 66 attached to the tip of the fire hose 62 that has been pulled out to the outside from the hose outlet where the hose storage door 30 is open. Also, remove the hose joint 60 from the pipe 3614 of the valve storage part 46, pull out the fire hose 62 to the outside, and drain the water. Since an automatic drain valve (not shown) is provided at a lower position below the pipe 3614, it is also possible to drain the water by pulling out the fire hose 62 to the outside without removing the hose joint 60.

[0145] Subsequently, connect the hose joint 60 of the drained fire hose 62 to the pipe 3614 of the valve storage part 46, and perform the operation of winding back the fire hose 62 in a clockwise direction from the outside to the inside by the support of the hose storage shelf structure 78 of the hose storage part 48. When the operation of winding back the fire hose 62 is completed, attach the water discharge nozzle 66 to the tip of the fire hose 62 and hold the water discharge nozzle 66 by the nozzle holder 67 of the first housing 11a to complete the restoration work.

[0146] In this way, in the operation of winding back the fire hose 62 by the support of the hose storage shelf structure 78 of the hose storage part 48, no special jig or the like is required, and it is possible to easily wind back the fire hose 62 to the hose storage part 48 of the third housing 11c.

[0147] (e8. Other embodiments of the opening and closing structure of the fire hydrant door) Next, another embodiment of the opening and closing structure of the fire hydrant door 14 provided in the first housing 11a will be described. In this description, reference is made to FIG. 12 showing another embodiment of the opening and closing structure of the fire hydrant door in a cross-section from the side, and FIG. 13 showing the open state of the fire hydrant door and the hose storage door according to the opening and closing structure of FIG. 12 from the front. Note that FIG. 12(A) shows the closed state of the fire hydrant door and the hose storage door, and FIG. 13(B) shows the open state of the fire hydrant door and the hose storage door.

[0148] As shown in FIG. 12(A), a fire hydrant door 14 is disposed at the front door opening of the fire hydrant equipment storage section 40 of the first housing 11a so as to be openable and closable upward by hinges 14a on both sides of the upper end. Also, a spare parts door 1420 is disposed at the front door opening of the spare parts storage section 47 of the first housing 11a so as to be openable and closable upward by hinges 14b on both sides of the upper end.

[0149] Inside the fire hydrant door 14, for example, a gas spring 92 is disposed as a mechanism for opening the fire hydrant door 14. The gas spring 92 has a piston slidably provided in a cylinder 9210, and a rod 9212 connected to the piston is taken out upward. The cylinder 9210 is rotatably supported at its lower end by a shaft portion 9216 at the rear end of the bottom of the first housing 11a, and the rod 9212 drawn upward is rotatably supported at its tip by a door support portion 9214 on the back side of the fire hydrant door 14.

[0150] As shown in FIG. 12(A), the fire hydrant door 14 is held in the closed position by a door opening and closing handle 1410. In this state, the gas spring 92 biases the fire hydrant door 14 obliquely upward via the rod 9212 by the compression of the inert gas by the piston provided in the cylinder 9210.

[0151] On the front side of the third housing 11c serving as the hose storage section 48, a hose storage door 30 is disposed so as to be openable and closable vertically by a hinge 30a at the lower end. A door locking portion 3014 extending above the door is located inside the lower end of the fire hydrant door 14, and the hose storage door 30 is held in the closed position.

[0152] In this state, when the closing hold of the fire hydrant door 14 is released by operating the door handle 1410, as shown in FIG. 12(B), the fire hydrant door 14 is pushed up by the rod 9212 of the gas spring 92, and the front surface of the first housing 11a is opened as shown in FIG. 13.

[0153] Further, with the opening of the fire hydrant door 14, the closing hold of the hose storage door 30 by the door locking portion 3014 of the hose storage door 30 is released. As shown in FIG. 12(B), the hose storage door 30 opens downward about the hinge 30a, and the hose outlet 86 partitioned by the guide frame 84 is exposed as shown in FIG. 13.

[0154] Therefore, when a road user takes out the water discharge nozzle 66 from the nozzle holder 67 in the first housing 11a, the portion of the fire hose 62 from the first housing 11a to the third housing 11c is pulled forward. Subsequently, the fire hose 62 stored in the hose storage portion 48 is drawn out through the horizontally long opening portion of the hose outlet 86 partitioned by the guide frame 84. In this case, since the fire hose 62 is directly drawn out from the hose storage portion 48 of the third housing 11c without passing through the first housing 11a, the degree of bending of the fire hose 62 is suppressed, and it is possible to smoothly pull it out with a light force from the hose outlet 86 partitioned by the guide frame 84.

[0155] Also, when a road user takes the water discharge nozzle 66 and draws out the fire hose 62, the fire hydrant valve 56 is opened by pulling down the fire hydrant valve opening / closing lever 70 in the first housing 11a downward, and the fire hose 62 is drawn out toward the fire occurrence location while discharging the fire extinguishing water from the water discharge nozzle 66.

[0156] As shown in FIG. 12(B), to close the opened fire hydrant door 14, first, with the hose storage door 30 of the third housing 11c closed, the opened fire hydrant door 14 is pushed down against the gas spring 92 and held in the closed position by locking the door opening / closing handle 1410 at the closed position.

[0157] The opening and closing of the spare part door 1420 arranged in the spare part storage section 47 is as follows: with the fire hydrant door 14 being kept closed, an attendant operates the door opening / closing handle provided on the spare part door 1420 to release the closed state, opens it upward around the hinge 14b, and holds it in the open position by means of a stay or the like provided inside the door.

[0158] [f. Fire Hydrant Device of the Second Embodiment] Subsequently, a second embodiment of the fire hydrant device will be described. In this description, reference will be made to FIG. 14 showing the hose storage structure provided in the second embodiment of the fire hydrant device with the front surfaces of the first housing and the third housing opened and viewed from the front, FIG. 15 showing the fire hydrant device viewed from the front excluding the guide frame partitioning the hose outlet from the third housing in FIG. 14, and FIG. 16 showing a cross-section of the internal structure of the fire hydrant device in FIG. 14 as viewed from the right side with the fire hydrant door and the hose storage door opened. Note that FIG. 16(A) shows the closed state of the fire hydrant door and the hose storage door, and FIG. 16(B) shows the open state of the fire hydrant door and the hose storage door. Also, the number of turns of the fire hose stored in FIGS. 14 to 16 does not necessarily match the number of turns described in the specification, and is shown only as an example.

[0159] In the second embodiment of the fire hydrant device, as shown in FIG. 14, a hose storage structure for storing the fire hose 62 in an inclined overlapping winding manner is provided in the hose storage section 48 of the third housing 11c. Since the other structures are the same as those of the fire hydrant device of the first embodiment shown in FIGS. 1 to 13, the description thereof will be omitted.

[0160] Describing the hose storage structure provided in the fire hydrant device of the second embodiment, as shown in FIG. 16(A), an inclined plate 94 is arranged at the bottom of the hose storage section 48 so as to be inclined downward obliquely forward with respect to the bottom of the hose storage section 48 at an inclination angle θ. The inclined plate 94 is arranged to wind the fire hose 62 along the inner wall of the housing on the inclined surface and stack it, so as to wind the fire hose 62 obliquely (inclined overlapping winding) at an inclination angle θ with respect to the bottom inside the housing.

[0161] Here, when the fire hose 62 is wound around inside the third housing 11c, in order to bend the fire hose 62 on both the left and right sides so that it does not bend, a bending diameter equal to or greater than a predetermined bending allowable diameter D must be ensured by the diameters of the semi-circular portions on both the left and right sides. However, when the depth width L (width in the front-rear direction) of the third housing 11c is thinned down to about 250 mm to an extent that allows the storage of a fire extinguisher, although the bending allowable diameter D varies depending on the manufacturer, generally about 340 mm is required. When the fire hose 62 is wound around parallel to the bottom inside the housing (parallel winding), since the depth width L of the third housing 11c is less than the bending allowable diameter D, in a thin-type fire hydrant device, the fire hose 62 cannot be stored by parallel winding.

[0162] Therefore, in the present embodiment, an inclined plate 94 having a plate width equal to or greater than the bending allowable diameter D of the fire hose 62 (width in the direction corresponding to the depth width of the third housing 11c in the case of parallel winding) is disposed at the bottom of the hose storage portion 48, and the fire hose 62 is wound around on the inclined surface of the inclined plate 94 along the inner wall of the housing, thereby enabling the storage of the 30 m long fire hose 62 that was also stored in a conventional fire hydrant device.

[0163] Here, when the plate width of the inclined plate 94 is the bending allowable diameter D, the inclination angle θ1 at which the inclined plate 94 is installed is cosθ1 = L / D From the relational expression, θ1 = cos -1 (L / D) and since a plate width equal to or greater than the bending allowable diameter D is ensured, the inclination angle θ is set to an angle equal to or greater than θ1.

[0164] For example, when the bending allowable diameter D of the fire hose is 340 mm and the depth width L of the third housing 11c is 250 mm, since the inclination angle θ1 is approximately 43°, if a margin is provided for the plate width of the inclined plate 94 with respect to the bending allowable diameter D, for example, the inclination angle θ is set to approximately 45° (the plate width of the inclined plate 94 when the inclination angle θ is 45° is about 350 mm).

[0165] Then, when the width (lateral width in the left - right direction) of the hose storage part 48 is, for example, 2000 mm, the length per turn of the fire - fighting hose 62 that is inclined and wound on the inclined surface of the inclined plate 94 is approximately 4.4 m. In the case of a 30 - m - long fire - fighting hose 62, it can be stored by inclined overlapping winding about 6.8 turns. Incidentally, the lateral width of the hose storage part 48 can be arbitrary as long as it has a size capable of storing the fire - fighting hose 62. For example, if the lateral width is 1800 mm, the length per turn of the fire - fighting hose 62 that is inclined and wound is approximately 4.0 m, and a 30 - m fire - fighting hose 62 can be stored by inclined overlapping winding about 7.5 turns.

[0166] Also, as shown in FIGS. 15 and 16(A)(B), in the hose storage part 48, a plurality of struts 96 that support the depth - side (rear - side, upper - side of the inclined surface) of the fire - fighting hose 62 that is inclined and wound on the inclined surface of the inclined plate 94 penetrate the inclined plate 94 and stand up from the bottom inside the housing, for example, at three positions on the left and right sides and the center of the hose storage part 48. The struts 96 surely prevent the depth - side of the overlapped - wound fire - fighting hose 62 from slipping down and collapsing along the inclined surface of the inclined plate 94 due to its own weight, and maintain the inclined overlapping winding state of the fire - fighting hose 62. Incidentally, the number, position, etc. of the struts 96 can be arbitrary, and a configuration in which they stand up at two positions on the left and right sides of the hose storage part 48 may also be possible.

[0167] When a road user uses the fire hydrant, when the door opening - closing handle 1410 of the fire hydrant door 14 shown in FIG. 16(A) is opened, the closing hold (lock) of the fire hydrant door 14 is released, and the fire hydrant door 14 slides upward by the gas spring 92 and opens as shown in FIG. 16(B). Along with the opening of this fire hydrant door 14, the closing hold of the door locking part 3014 of the hose storage door 30 is released, and the hose storage door 30 rotates downward and opens.

[0168] Therefore, as shown in FIG. 14, the road user lowers the fire hydrant valve opening / closing lever 70 disposed in the first housing 11a to the lower open position, sends a pump start signal to the disaster prevention receiving panel by switching on the pump start interlocking device 74 to cause start control of the fire pump, and then takes out the drain nozzle 66 held in the first housing 11a and pulls out the fire hose 62.

[0169] In this case, the fire hose 62 stored in the hose storage section 48 in an inclined overlapping manner is pulled out to the outside from the hose outlet 86 partitioned by the guide frame 84 positioned forward without being restricted by the support column 96 through the empty space between the tip of the erected support column 96 and the hose storage section 48, and the fire hose 62 can be smoothly pulled out with a light force without generating any forced bending or breakage in the pulled-out fire hose 62.

[0170] [g. Fire Hydrant Device of the Third Embodiment] Subsequently, a third embodiment of the fire hydrant device will be described. In this description, reference is made to FIG. 17 showing the hose storage structure provided in the fire hydrant device of the third embodiment with the front surfaces of the first housing and the third housing opened and shown from the front, FIG. 18 showing the fire hydrant device from the front excluding the guide frame partitioning the hose outlet from the third housing of FIG. 17, and FIG. 19 schematically showing the storage compartments of the fire hose formed by dividing the hose storage section in the depth direction.

[0171] In the third embodiment of the fire hydrant device, as shown in FIG. 17, a hose storage structure is provided in the hose storage section 48 of the third housing 11c, in which the fire hose 62 is sequentially wound in a loop shape into storage compartments divided in the depth direction. Since the other structures are the same as those of the fire hydrant device of the first embodiment shown in FIGS. 1 to 13, the description thereof will be omitted.

[0172] (g1. Hose Storage Structure) The hose storage structure provided in the fire hydrant device according to the third embodiment will be described. As shown in FIG. 18, a hose storage section 48 is formed on the left side of the third housing 11c, and a hose storage cage 98 that functions as a hose storage compartment is disposed on the bottom side of the hose storage section 48. As shown in FIG. 19, the hose storage cage 98 realizes a hose storage compartment 9800 that is virtually formed within the third housing 11c.

[0173] The hose storage compartment 9800 is formed in the hose storage section 48 within the third housing 11c, which is disposed in the space between the device main body composed of the first housing 11a and the second housing 11b and the road surface of the supervisor passage 34, and is divided into a first compartment 9800a, a second compartment 9800b, a third compartment 9800c, and a fourth compartment 9800d in the depth direction. In each of the first compartment 9800a to the fourth compartment 9800d, the fire hose 62 is sequentially wound in a loop shape in a vertical winding manner and is stored so as to be freely pulled out.

[0174] Here, the number of compartments divided in the depth direction of the hose storage compartment 9800 is arbitrary, but it is the number of compartments corresponding to the depth width of the third housing 11c, the outer diameter and the minimum bending allowable diameter of the fire hose 62, and the hose length per turn determined by the vertical width and the horizontal width of the hose storage section 48.

[0175] In the present embodiment, for example, the outer diameter of the fire hose 62 is 40 mm, the minimum bending allowable diameter is 340 mm, the horizontal width of the hose storage section 48 is 2000 to 2200 mm, and the vertical width is 800 mm. In this case, the hose length per turn is 6.5 to 6.8 m. Therefore, the number of compartments for storing the 30 m fire hose 62 is 4 to 5 compartments.

[0176] When the number of compartments of the hose storage compartment 9800 is 4 compartments, if the depth width of the third housing 11c is 250 mm, each compartment width is 62.5 mm, and it is possible to wind one hose with an outer diameter of 40 mm. Also, when the number of compartments of the hose storage compartment 9800 is 5 compartments, each compartment width is 50 mm, and in this case as well, it is possible to wind one hose with an outer diameter of 40 mm.

[0177] The hose storage compartment 9800 shown in Fig. 19 is virtual. The structure in which the fire hose 62 is wound vertically in order and stored in the hose storage compartment 9800 for easy extraction is realized by a cage structure, a wire tension structure, or a box board structure, and by a plurality of slit openings formed in the depth direction at a predetermined height in the third housing 11c.

[0178] (g2. Slit openings formed by the cage structure) The slit openings formed by the cage structure will be described. For this description, refer to Fig. 20, which shows the hose storage cage arranged in the third housing of Fig. 18 taken out and shown in a perspective view, and Fig. 21, which shows the hose storage cage taken out and forming the slit openings in the third housing. Note that Fig. 21(A) shows the front of the third housing excluding the front decorative panel, Fig. 21(B) shows the front of the hose storage cage, Fig. 21(C) shows the plan view of the hose storage cage, and Fig. 21(D) shows the side view of the hose storage cage.

[0179] The hose storage cage 98 shown in Figs. 20 and 21 is a cage structure (basket structure) composed of non-flexible wire rods, for example, metal wire rods such as steel. The horizontal cage 98a, vertical cage 98b, bottom cage 98c, diagonal cage 98d, and depth cage 98e are configured by fixing the cage intersections by welding or the like so as to form slit openings 100a to 100d divided into four in the depth direction at a predetermined height.

[0180] If the outer diameter of the metal wire rod used for the hose storage cage 98 is about 1 to 1.5 mm, the depth width occupied by the five horizontal cages 98a arranged in the depth direction is 5 to 7.5 mm wide. With respect to the depth width of 250 mm of the third housing 11c, the remaining depth width is 242.5 to 245 mm. Therefore, even including the plate members arranged front and back, it is possible to secure a depth opening width of the slit openings 100a to 100d of about 60 mm with sufficient margin with respect to the hose outer diameter.

[0181] Also, the height width H11 at which the slit openings 100a to 100d of the hose storage cage 98 arranged in the third housing 11c are located is arbitrary, but it is at least half of the height width inside the housing. For this reason, the hose storage cage 98 has the slit openings 100a to 100d located near the center in the height direction in one turn of the fire hose 62 that is wound along the left inner surface, bottom surface, right inner surface, and upper surface in the third housing 11c, supports the fire hose 62, and stores the wound fire hose 62 so that it can be freely drawn out.

[0182] With respect to the slit openings 100a to 100d formed in the third housing 11c in this way, the fire hoses 62 are sequentially wound and stored in a loop shape.

[0183] (g3. Hose storage by loop-shaped winding) Next, hose storage in which the fire hose is wound and stored in a loop shape with respect to the slit opening will be described. In this description, refer to FIG. 22 which schematically shows the fire hose wound in a loop shape in the slit opening of the hose storage portion. Note that FIGS. 22(A) to (D) show the hose winding for the four slit openings separately from the front, and FIG. 22(E) shows the hose winding for the slit opening in a plan view.

[0184] After the assembly of the fire hydrant device 10 is completed in the manufacturing process at the factory, open the inspection door 17 on the right side of the third housing 11c shown in FIG. 1 to expose the valve storage portion 46 as shown in FIG. 4. Also, release the closure of the decorative plate 12c of the third housing 11c by screwing etc., and open the upper part with the hinges on both sides of the lower end as a forward tilt open position, and hold the forward tilt open position with a stay or a chain.

[0185] Subsequently, the operation of winding the fire hose 62 into the slit opening 100a located at the innermost part of the hose storage section 48 shown in Fig. 22(E) is performed. The operation of winding the fire hose 62 is to connect the fire hose 62 connected to the piping 3614 of the valve storage section 46 formed on the right side of the third housing 11c shown in Fig. 17 with a hose joint 60, and as shown in Fig. 22(A), pull it in from the lower side as the hose winding section 62a, and wind the fire hose in a loop along the inner peripheral surface of the vertically rotating housing, that is, the inner peripheral surface of the bottom surface, the left inner side surface, and the vicinity of the center on the lower side of the upper surface.

[0186] Subsequently, as shown in Fig. 22(E), while moving the fire hose 62 toward the slit opening 100b one step forward, similarly, winding is performed in a loop along the inner peripheral surface of the vertically rotating housing, and this is repeated up to the slit opening 100b shown in Fig. 22(B) and the slit opening 100c shown in Fig. 22(C).

[0187] In the case of winding into the last slit opening 100d, as shown in Fig. 22(D), the fire hose 62 wound from the left inner side surface to the lower side of the upper surface is taken out upward as the hose unwinding section 62b, and is connected to the water discharge nozzle 66 held by the nozzle holder 67 of the first housing 11a shown in Fig. 18.

[0188] In such an operation of winding the fire hose 62 in a loop, the operation is performed with the water discharge nozzle 66 removed from the tip of the hose. After winding, the water discharge nozzle 66 is attached to the tip of the fire hose 62 that has been wound, and is pulled out into the first housing 11a and held by the nozzle holder 67.

[0189] Here, when the size of the hose storage section 48 is, for example, 800 mm in length and 2000 mm in width, since the hose length per turn when the fire hose 62 is wound in a loop in the hose storage cage 98 is about 6.5 m as described above, the hose length for 4 turns of winding by the slit openings 100a to 100d is 26 m. However, by curving the straight part of the hose winding to increase the hose length per turn, it is possible to store the 30 m fire hose 62.

[0190] Next, the case where a road user uses a fire hydrant will be described. In this description, reference is made to FIG. 23, which shows a cross-section of the internal structure of the fire hydrant device of FIG. 17 as viewed from the right side with the fire hydrant door and the hose storage door open. Note that FIG. 23(A) shows the closed state of the fire hydrant door and the hose storage door, and FIG. 23(B) shows the open state of the fire hydrant door and the hose storage door.

[0191] When a road user uses a fire hydrant, when the door opening / closing handle 1410 of the fire hydrant door 14 shown in FIG. 23(A) is opened, the fire hydrant door 14 slides upward by the gas spring 92 and opens as shown in FIG. 23(B). With the opening of this fire hydrant door 14, the closing hold of the hose storage door 30 is released, and the hose storage door 30 rotates downward and opens.

[0192] Therefore, the road user lowers the fire hydrant valve opening / closing lever 70 arranged in the first housing 11a to the lower open position as shown in FIG. 17, sends a pump start signal to the disaster prevention receiving panel by switching on the pump start interlocking device 74 to perform start control of the fire pump, and then takes out the water discharge nozzle 66 held in the first housing 11a and pulls out the fire hose 62.

[0193] In this case, the fire hose 62 stored in a vertically looped shape in the hose storage cage 98 of the hose storage section 48 is pulled out to the outside from the hose outlet 86 partitioned by the guide frame 84 located at the upper front as shown in FIG. 23(B), and the fire hose 62 can be smoothly pulled out with a light force without generating any forced bending or kinking in the pulled-out fire hose 62. Note that the recovery operation of winding the fire hose 62 back into the hose storage section 48 after the fire hydrant device 10 has been used is the same as the winding-in operation performed after the assembly of the fire hydrant device 10 is completed in the manufacturing process in the factory described above.

[0194] [h. Fire Hydrant Device of the Fourth Embodiment] Next, a fourth embodiment of the fire hydrant device will be described. In this description, the hose storage structure provided in the fourth embodiment of the fire hydrant device is shown in FIG. 24 with the front surfaces of the first housing and the third housing opened and viewed from the front, and FIG. 25 showing the fire hydrant device from the front excluding the guide frame that partitions the hose outlet from the third housing of FIG. 24 is referred to.

[0195] As shown in FIG. 24, the fire hydrant device of the fourth embodiment is characterized in that a hose storage structure for storing the fire hose 62 by winding it around the outside is provided in the hose storage portion 48 of the third housing 11c. Since the other structures are the same as those of the fire hydrant device of the first embodiment, the description thereof will be omitted.

[0196] (h1. Hose storage structure) The hose storage structure provided in the fire hydrant device of the fourth embodiment will be described. As shown in FIG. 25, a hose winding portion 102 is arranged in the hose storage portion 48 of the third housing 11c, and the fire hose 62 is stored so as to be freely pulled out by winding it around the outside. The outside winding of the fire hose 62 around the hose winding portion 102 is a multi-row reciprocating overlapping winding, and it is the number of rows in the depth direction and the number of overlapping winding times in the vertical direction that can store the 30 m fire hose 62 using a shape-retaining hose.

[0197] At two locations on the left and right on the upper surface side of the hose winding portion 102, first hose restraining portions 106 are provided. The first hose restraining portions 106 support the front side of the fire hose 62 wound around the outside of the hose winding portion 102.

[0198] On the left and right sides of the lower surface of the hose winding part 102, two second hose restraining parts 108 are provided. The second hose restraining part 108 is pivotally supported at its lower end so as to be rotatable in the vertical direction between a vertical position on the back side and a horizontal position projecting forward about an axis. Therefore, when the fire hose 62 is wound around the hose winding part 102 externally, the second hose restraining part 108 is rotated to the horizontal position projecting forward to position the hose winding position with respect to the lower surface side of the hose winding part 102, and when the external winding is completed, it is rotated to the vertical position on the back side shown in the figure and retracts. Note that "vertical" does not strictly limit to being perpendicular to the object, but includes being approximately perpendicular to the object, and the same applies to "horizontal".

[0199] (h2. Cylindrical Structure of Hose Winding Part) Next, the cylindrical structure of the hose winding part will be described. For this description, refer to FIG. 26 showing the hose winding part arranged in the third housing of FIG. 25 taken out, FIG. 27 showing a cross-section seen from the right side of the procedure of externally winding the hose around the hose winding part of the third housing of FIG. 25, and FIG. 28 showing a cross-section seen from the right side of the internal structure of the fire hydrant device of FIG. 25 with the fire hydrant door and the hose storage door opened. Note that FIG. 26(A) shows the front of the third housing, and FIG. 26(B) shows a cross-section taken along the cutting line a-a of FIG. 26(A). Also, FIG. 27(A) shows the state before the hose is wound, FIG. 27(B) shows the order of overlapping winding of the hose, and FIG. 27(C) shows the state after the hose winding is completed. Further, FIG. 28(A) shows the closed state of the fire hydrant door and the hose storage door, and FIG. 28(B) shows the open state of the fire hydrant door and the hose storage door.

[0200] As shown in FIG. 26(A), the hose winding part 102 is a horizontally long oval cylindrical body fixed to the back surface inside the third housing 11c and extending forward, and the opening surface of the cylindrical body is an inclined opening surface 104 cut out in the depth direction obliquely downward from the front of the upper surface. Therefore, the cylindrical body constituting the hose winding part 102 has an upper surface part 102a and a part of the left and right semi-circular parts 102b, but has a shape without a lower surface part due to the formation of the inclined opening surface 104.

[0201] In this way, since the lower surface portion of the cylindrical body does not exist due to the formation of the inclined opening surface 104, when the fire hose 62 wound around the hose winding portion 102 (wound around in multiple rows and overlapping back and forth) is pulled out, it is possible to avoid a situation where the fire hose 62 is obstructed (caught) by the lower surface portion of the cylindrical body and cannot be pulled out.

[0202] Also, the diameters of the semi-circular portions 102b on both sides (left and right) of the hose winding portion 102 are at least the minimum bending diameter of the fire hose 62. In the embodiment, a shape-retaining hose with an outer diameter of 40 mm is used as the fire hose 62, and its minimum bending diameter is arbitrary. For example, it may be 340 mm, and with a margin, it is 400 mm.

[0203] Also, the lateral width (left - right width) of the upper surface portion 102a of the hose winding portion 102 is arbitrary. However, in order to ensure a sufficient hose length per turn, for example, the lateral width (left - right width) from the left end of the hose storage portion 48 to the partition wall is 2000 mm, the radius of the semi-circular portion 102b is 200 mm, and the clearance space between the inner surface of the side wall of the semi-circular portion 102b corresponds to the number of hose overlapping turns. For example, if it is 200 mm, the lateral width of the upper surface portion 102a is, for example, 1200 mm.

[0204] Therefore, when the fire hose 62 is wound around the hose winding portion 102, the hose length per turn, when the outer diameter of the hose is 40 mm and the number of overlapping turns is indicated by the number of layers, is approximately 3.6 m for the first layer, approximately 3.9 m for the second layer, and approximately 4.2 m for the third layer.

[0205] Also, the depth width of the upper surface portion 102a of the hose winding portion 102 becomes 160 mm when a fire hose with an outer diameter of 40 mm can be wound around in 4 rows. Therefore, if the depth width of the hose storage portion 48 (the third housing 11c) is, for example, 250 mm, a free space for forming a hose drawing space with a depth width of 90 mm is formed in front of the hose winding portion 102.

[0206] In addition, as shown in FIGS. 27(B) and (C), for the multiple rows of reciprocating overlapping winding around the hose winding portion 102, for example, there are 4 rows in the first layer and 3 rows in the second layer, and this is repeated hereinafter.

[0207] Therefore, the hose length of the 4 rows in the first layer is 14.4 m, the hose length of the 3 rows in the second layer is 11.7 m, and the cumulative length is 26.1 m. Up to a hose length of 30 m, the remaining length is 3.9 m. The hose length of the 4 rows in the third layer is 16.8 m, and the cumulative length is 42.9 m. The outer winding of the hose length of 30 m required for the first row in the third layer is completed.

[0208] (h3. First Hose Suppressing Portion) Next, the first hose suppressing portion 106 provided on the upper surface portion 102a of the hose winding portion 102 will be described. As shown in FIG. 26(A), the first hose suppressing portion 106 is arranged at two predetermined positions on the left and right of the open end which is the overhanging portion of the upper surface portion 102a of the cylindrical body constituting the hose winding portion 102.

[0209] The structure, shape, and material of the first hose suppressing portion 106 are arbitrary. For example, it is an L-shaped plate-like member shown in FIG. 26(B), and a deformable flexible material such as rubber is used. The first hose suppressing portion 106 has its lower part fixed to the open end of the upper surface portion 102a by the fixing portion 106b, and the standing portion 106a suppresses the opening surface side of the fire extinguishing hose 62 wound around the upper surface portion 102a to support it so as not to fall off. On the other hand, when the fire extinguishing hose 62 is pulled out from the hose storage portion 102, it may be pressed by the fire extinguishing hose 62. In this case, it is deformable so as to bend outward and not hinder the pulling out of the hose.

[0210] (h4. Second Hose Suppressing Portion) Next, the second hose suppressing portion 108 provided on the lower surface side of the hose winding portion 102 will be described. As shown in FIG. 26(A), the second hose suppressing portion 108 is arranged at two predetermined positions on the left and right of the back surface which is the lower surface side of the cylindrical body constituting the hose winding portion 102.

[0211] The structure and shape of the second hose holding part 108 are arbitrary. For example, as shown in Fig. 26(A), it is a plate member of a predetermined length. As shown in Fig. 26(B), the lower end of the second hose holding part 108 is rotatably supported by a torque hinge 110 on the back surface of the hose winding part 102. The torque hinge 110 rotates between a vertical position along the back surface of the hose winding part 102 and a horizontal position protruding forward, and torque is generated when rotating, so that the second hose holding part 108 can be held at an arbitrary position within the rotation range.

[0212] As shown in Fig. 26(B), since the cylindrical body of the hose winding part 102 has no lower surface part due to the formation of the inclined opening surface 104, when the staff winds the fire hose 62 externally, the position of the lower surface of the cylindrical body is not determined, and the external winding of the hose on the lower side of the hose winding part 102 may be uneven and vary without being aligned.

[0213] Therefore, when the staff winds the fire hose 62 externally around the hose winding part 102, the second hose holding part 108 is rotated to the horizontal position as shown in Fig. 27(A), and by positioning the external winding position of the hose on the lower surface side of the hose winding part 102, it becomes possible to wind the hose externally in an aligned manner also on the lower side of the hose winding part 102, similar to the upper surface part 102a.

[0214] Also, after the external winding of the fire hose 62 is completed, the second hose holding part 108 in the horizontal position will interfere with the pulling out of the fire hose 62. Therefore, it is rotated from the horizontal position by the torque hinge 1106 and held in the retracted state at the vertical position on the back side.

[0215] (h5. External winding operation of the fire hose) Next, the external winding operation of the fire hose on the hose winding part arranged in the third housing 11c will be described. Note that the hose rewinding operation performed as a recovery operation is the same after the road user takes out the water discharge nozzle 66, pulls out the fire hose 62, and conducts a fire extinguishing activity.

[0216] After the assembly of the fire hydrant device 10 is completed in the manufacturing process at the factory, open the inspection door 17 on the right side of the third housing 11c shown in FIG. 1 to expose the valve storage part 46 as shown in FIG. 4. Also, release the closure of the decorative panel 12c of the third housing 11c by screwing or the like, and set it to the forward-tilt open position where the upper part is opened with the hinges on both lower ends as the axis. The forward-tilt open position is held by a stay or a chain.

[0217] For the outer winding operation of the fire hose 62, first, as shown in FIG. 27(A), the second hose holding part 108 pivotally supported by a torque hinge 110 on the lower surface side of the hose winding part 102 is rotated to the horizontal position, and the lower surface position of the outer winding of the hose is positioned.

[0218] Subsequently, as shown in FIG. 27(B), the first layer of the fire hose 62 is wound around the hose winding part 102 in four rows from the rear side (back side) to the front side. Subsequently, the second layer is wound around the outer circumference of the first layer in three rows from the front side to the rear side, and further, the third row is wound around the outer circumference of the second layer in four rows from the rear side to the front side, and the outer winding of the fire hose of 30 m or more is completed.

[0219] When the outer winding of the fire hose 62 is completed, as shown in FIG. 27(C), the second hose holding part 108 pivotally supported by the torque hinge 110 is rotated and held in the back position, and thus the winding operation of the fire hose 62 is completed.

[0220] When a road user uses the fire hydrant, when the door opening / closing handle 1410 of the fire hydrant door 14 shown in FIG. 28(A) is opened, the fire hydrant door 14 slides upward by the gas spring 92 and opens as shown in FIG. 28(B). Along with the opening of the fire hydrant door 14, the closing hold of the hose storage door 30 is released, and the hose storage door 30 rotates downward and opens.

[0221] Therefore, as shown in Fig. 24, the road user lowers the fire hydrant valve opening / closing lever 70 disposed in the first housing 11a to the lower open position, switches on the pump start interlocking device 74 to send a pump start signal to the disaster prevention receiving panel to control the start of the fire pump, and then takes out the drain nozzle 66 held in the first housing 11a and pulls out the fire hose 62.

[0222] In this case, the fire hose 62 wound around the hose winding portion 102 of the hose storage portion 48 is drawn out to the outside from the hose outlet 86 partitioned by the guide frame 84 located in the front, and the fire hose 62 can be smoothly drawn out with a light force without generating any unreasonable bending portions or breaks in the drawn fire hose 62.

[0223] [i. Fire Hydrant Device of the Fifth Embodiment] Subsequently, the fire hydrant device of the fifth embodiment will be described. In this description, reference is made to Fig. 29 showing the fifth embodiment of the fire hydrant device with the fire extinguisher storage portion arranged in the space between the device main body and the road surface of the inspector passage together with the hose storage portion and the valve storage portions, and Fig. 30 showing the fifth embodiment of the fire hydrant device of Fig. 29 with the front surface of the housing opened and viewed from the front.

[0224] As shown in Fig. 29, the fire hydrant device 10 of this embodiment is installed on a pedestal 32 installed on the road surface of the inspector passage 34. The housing of the fire hydrant device 10, the device main body, has the first housing 11a, the second housing 11b, and the third housing 11c connected and fixed from the right side to the left side. The hose storage housing disposed between the device main body and the road surface of the inspector passage 34 has the fourth housing 11d and the fifth housing 11e connected and fixed from the right side to the left side.

[0225] As shown in FIG. 30, the first housing 11a that constitutes the apparatus main body serves as a fire hydrant equipment storage section 40, the second housing 11b serves as an electrical equipment storage section 25, and the third housing 11c serves as a spare parts storage section 124. Further, the fourth housing 11d that constitutes the hose storage housing serves as a valve storage section 46 and a hose storage section 48, and the fifth housing 11e serves as a fire extinguisher storage section 126. Further, the fourth housing 11d and the fifth housing 11e that are connected and fixed in the left - right direction function as a mount for attaching and fixing the first housing 11a, the second housing 11b, and the third housing 11c that are connected and fixed in the left - right direction to a tunnel wall surface at a predetermined height above the road surface of the monitor passage 34 in contact with or close to it.

[0226] Here, since the fire extinguisher storage section 126 is not arranged on the apparatus main body side, it is not necessary to consider a fire extinguisher having the maximum height as the equipment to be stored in the fire hydrant apparatus 10 in the apparatus main body composed of the first housing 11a, the second housing 11b, and the third housing 11c, and the height of the housing can be reduced. For example, in the first embodiment of FIG. 1, in order to store a fire extinguisher, as shown in FIG. 2, the height Hw of the apparatus main body is 700 mm. However, in this embodiment, since there is no need to store a fire extinguisher, the height Hw of the apparatus main body can be reduced to, for example, 400 mm or less.

[0227] As shown in FIG. 29, a decorative frame 12a is attached to the front surface of the first housing 11a, and a fire hydrant door 14 that slides upward and opens is arranged at the door opening of the decorative frame 12a when the lock is released by the operation of a door opening and closing handle 1410.

[0228] As shown in FIG. 30, inside the first housing 11a that serves as the fire hydrant equipment storage section 40, predetermined fire hydrant equipment including a water supply tap 50, a drain nozzle 66, an operation box 68, a fire hydrant valve opening and closing lever 70, and a pump starting device 76 is stored. Since the details of each are the same as those in the case of the first embodiment shown in FIG. 4, the description is omitted.

[0229] As shown in Fig. 29, a decorative frame 12b is attached to the front surface of the second housing 11b. Above the door opening of the decorative frame 12b, an electrical equipment door 18 that opens and closes upward by hinges 18a on the left and right at the upper ends is arranged. Below it, an auxiliary door 20 that opens and closes downward by hinges 20a on the left and right at the lower ends and enables access to the internal terminal boxes 25a and 25b is arranged.

[0230] Here, since the height of the second housing 11b is reduced to, for example, 400 mm corresponding to the height Hw of the apparatus main body, the lateral width of the second housing 11b is larger than that in the first embodiment shown in Figs. 1 and 4. For this reason, the electrical equipment door 18 that opens upward and the auxiliary door 20 that opens downward are also horizontally long doors.

[0231] On the electrical equipment door 18, as electrical equipment, for example, a red indicator lamp 22, a transmitter 24, and a response lamp 28 are arranged from the right side to the left side. Inside the door, a telephone jack 26 is arranged. Also, on the rear surface inside the second housing 11b opposite to the auxiliary door 20, a high-voltage terminal box 25a and a low-voltage terminal box 25b are arranged side by side in the left-right direction.

[0232] A decorative panel 12c is attached to the front surface of the third housing 11c. In the door opening of the decorative panel 12c, when the lock is released by operating the door opening and closing handle 1210, a spare parts door 120 that opens horizontally to the left is arranged. As shown in Fig. 30, inside the spare parts door 120, for example, a spare parts storage section 124 is formed by dividing it vertically, and tools, test jigs, helmets, gloves, etc. necessary for the maintenance and management of the fire hydrant device 10 are stored as required.

[0233] On the front surface of the fourth housing 11d, which functions as a pedestal for mounting and fixing the first housing 11a, the second housing 11b, and the third housing 11c at a predetermined height above the road surface of the supervisor passage 34, as shown in FIG. 29, a decorative frame 12d is attached. When the lock is released by operating the door opening and closing handle 1710 at the door opening of the decorative frame 12d, an inspection door 17 that opens horizontally to the right is arranged. In the valve storage section 46 shown in FIG. 30, which is inside the door, predetermined valves including a fire hydrant valve 56 and an automatic pressure regulating valve 58 are stored. Since the details are the same as those in the first embodiment of FIG. 4, the description is omitted.

[0234] Horizontally long hose storage doors 30 are arranged on the upper part of the decorative frame 12d of the fourth housing 11d in the left - right direction so as to open downward about hinges 30a on both lower ends. The hose storage door 30 has a sub - door portion 3012 integrally formed near the upper part of the center of the horizontally long rectangular door body 3010 toward the first housing 11a side. At the upper tip of the sub - door portion 3012, a door locking portion 3014 is formed, which is located inside the fire hydrant door 14 and holds the hose storage door 30 in the closed position.

[0235] A guide frame 84 is arranged on the front surface of the housing on the back side of the hose storage door 30, forming a horizontally long hose outlet 86. Also, the guide frame 84 has a hose outlet curved portion 88 formed at the upper center of the horizontally long hose outlet 86. Since the details of the hose outlet structure provided in the fourth housing 11d are the same as those in the first embodiment of FIG. 4, the description is omitted.

[0236] As shown in FIG. 30, hose storage shelf structures 78 are arranged in three places in the hose storage section 48 of the fourth housing 11d. The hose storage shelf structures 78 store the fire - fighting hose 62 in a retractable manner by winding it inside. Since the details are the same as those in the first embodiments of FIGS. 4 to 6, the description is omitted.

[0237] In addition, the hose storage section 48 may be applied with any one of the hose storage structures of the second embodiment in which the fire hose 62 shown in FIGS. 12 to 14 is inclined and wound up for easy pulling out and storage, the hose storage structure of the third embodiment in which the fire hose 62 shown in FIGS. 15 to 21 is wound in a loop shape in the vertical direction for easy pulling out and storage, or the hose storage structure of the fourth embodiment in which the fire hose 62 shown in FIGS. 22 to 25 is wound externally for easy pulling out and storage.

[0238] As shown in FIG. 29, a decorative frame 12e is attached to the front surface of the fifth housing 11e. When the lock is released by operating the door opening and closing handle 1610 at the door opening on the left side of the decorative frame 12e, a fire extinguisher door 16 that opens horizontally to the left by a hinge 16a is arranged. In a fire extinguisher storage section 126 inside the door, for example, two fire extinguishers 19 are stored. In addition, a viewing window 1612 is provided on the fire extinguisher door 16 so that the presence or absence of a fire extinguisher can be confirmed from the outside.

[0239] Therefore, when a fire breaks out, a road user opens the fire extinguisher door 16 and takes out one or two fire extinguishers 19 with a chemical agent amount of 6 kg and a total weight of about 10 kg to carry out fire extinguishing activities. Since the fire extinguisher 19 is stored in the fifth housing 11e arranged at a low position between the device main body and the road surface of the supervisor passage 34, it is easy to take out the fire extinguisher 19, and damage caused by the fall of the fire extinguisher 19 can also be reduced.

[0240] [j. Fire Hydrant Device of the Sixth Embodiment] Subsequently, the fire hydrant device of the sixth embodiment will be described. In this description, reference is made to FIG. 31 showing the sixth embodiment in which upper and lower two-stage fire extinguisher storage sections are arranged on one side surface of the fire hydrant device from the front, and FIG. 32 showing a modified example of the sixth embodiment in which upper and lower two-stage fire extinguisher storage sections are arranged on both side surfaces of the fire hydrant device from the front.

[0241] As shown in FIG. 31, the fire hydrant device 10 of the present embodiment is installed on a pedestal 32 installed on the road surface of the supervisor passage 34. The device main body connects and fixes a first housing 11a and a second housing 11b from the right side to the left side, and a third housing 11c is arranged between the device main body and the road surface of the supervisor passage 34 in the hose storage housing. Further, a fourth housing 11d serving as a fire extinguisher storage section is arranged on the left side surface where the device main body obtained by connecting and fixing the first housing 11a and the second housing 11b and the hose storage section serving as the third housing 11c are arranged vertically.

[0242] Here, the first housing 11a and the second housing 11b of the device main body are the same as the first housing 11a and the second housing 11b of the fifth embodiment shown in FIGS. 29 and 30, and the third housing 11c serving as the hose storage section is the same as the fourth housing 11d of the fifth embodiment shown in FIGS. 29 and 30, so the description is omitted.

[0243] The fourth housing 11d serving as the fire extinguisher storage section has the same height as the fire hydrant device 10 with the device main body arranged above the hose storage section, for example, 1200 mm. The inside of the housing is partitioned vertically, and the fire extinguishers 19 are stored in two upper and lower stages.

[0244] A decorative frame 12d is attached to the front surface of the fourth housing 11d. The decorative frame 12d is formed with vertically long door openings corresponding to the two upper and lower fire extinguisher storage sections. When the lock is released by operating the door opening and closing handle 1610, a fire extinguisher door 16 that opens horizontally to the left by a hinge 16a is arranged. Further, viewing windows 1612 are provided on the fire extinguisher door 16 corresponding to each of the two upper and lower fire extinguisher storage sections, so that the presence or absence of a fire extinguisher can be confirmed from the outside.

[0245] Therefore, when a fire breaks out in the tunnel, road users will open the fire extinguisher door 16 and take out one or two fire extinguishers 19 with a chemical agent amount of 6 kg and a total weight of about 10 kg to carry out fire extinguishing activities. Since the lower fire extinguisher 19 is stored at a low position between the device main body and the road surface of the supervisor passage, it is easy to take out the fire extinguisher 19, and damage caused by the fall of the fire extinguisher 19 can also be reduced. Also, for the upper fire extinguisher 19, if the height of the fire hydrant device 10 is, for example, 1200 mm, the height of the handle part to be grasped when taking out the fire extinguisher 19 is at a relatively low position of about 1000 - 1100 mm, and safe extraction is possible even when stored in the upper part.

[0246] The fire hydrant device 10 shown in Fig. 32 has a device main body formed by connecting and fixing a first housing 11a and a second housing 11b, and a fourth housing 11d serving as a fire extinguisher storage part for storing the fire extinguishers 19 in two upper and lower stages is arranged on each of the left and right sides where a hose storage part serving as a third housing 11c is arranged vertically.

[0247] In this way, by arranging the fourth housing 11d serving as a fire extinguisher storage part on both sides of the fire hydrant device 10, it becomes possible to store four fire extinguishers 19, and the fire extinguishing ability using the fire extinguishers 19 can be doubled.

[0248] [k. 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.
