Description

The present invention relates to a fire hydrant facility and a fire hydrant device provided with a fire hydrant storage box for pulling out a hose with a nozzle to release fire hydrant water or fire hydrant foam.

Conventionally, emergency equipment has been installed in tunnels such as expressways and motorways to protect people and vehicles from fire accidents that occur in the tunnels.

Such emergency equipment includes a fire detector, a manual notification device, and an emergency telephone for fire monitoring and notification, a fire hydrant device for extinguishing a fire and preventing the spread of fire, and a tunnel frame. In order to protect from fire, water spray equipment that sprinkles fire extinguishing water from the water spray head is installed, and the equipment of emergency equipment is connected to the transmission line from the disaster prevention receiving panel installed in the monitoring center for monitoring and control. ing.

For example, fire hydrant devices are installed at intervals of 50 meters along the side wall facing the observer passage provided in the tunnel, and hoses and valves with nozzles attached to the tips are placed in a housing equipped with an openable fire hydrant door. It is stored.

In the water spray equipment, an automatic valve device is installed on the side wall that is integrated with or near the fire hydrant device, and the water supply pipes raised from the automatic valve device are connected to multiple water spray heads located at the top of the tunnel. ing.

By the way, in the automatic valve device provided in the conventional water spraying equipment, the inspection door can be freely attached to and detached from the opening of the housing in order to inspect the automatic valve stored in the housing at the time of periodic inspection or the like. It is provided in. For the inspection door of the automatic valve, for example, a steel plate with a thickness of about several millimeters is used as the inspection door, the inspection door is hung from the upper part of the housing opening, the lower side of the inspection door is positioned by the rubber stopper, and the weight of the inspection door is used. It is kept in a closed state.

On the other hand, the fire hydrant device is provided with a fire hydrant door that opens downward on the lower side of the housing opening and a maintenance door that opens upward on the upper side of the housing opening. It is possible to inspect the equipment inside the housing by opening the maintenance door, and there is no need for an inspection door that keeps the closed state by weight like an automatic valve device.

By the way, in an urban tunnel made by a shield method or the like, the fire hydrant device cannot be embedded and installed in the tunnel wall surface, and it is necessary to embed and install the fire hydrant device in the side surface (wall surface) of the observer passage.

However, when a fire hydrant device that opens the door forward like a conventional fire hydrant is installed in the observer passage, there is a problem that when the fire hydrant door opens, it exceeds the building limit and jumps out to the road side.

In order to solve this problem, the applicant of the present application has installed a fire hydrant storage box embedded in the observer passage, provided a front door that slides open and closes facing the road side, and opens and closes upward on the observer passage surface. We are studying a fire hydrant storage box with a structure with an upper door.

According to the fire hydrant storage box embedded in the observer passage in this way, when a fire occurs due to a vehicle accident, the user opens the front door facing the road, and the nozzle is wound inside the housing. The fire can be extinguished by pulling out the attached hose. In addition, when the vehicle stops in front of the fire hydrant device and cannot be operated from the front door, the upper door of the observer passage is opened so that the vehicle is wound inside the housing without being hindered by the stopped vehicle. A hose with a nozzle can be pulled out to extinguish the fire. Further, when the fire extinguishing work is completed, the hose is drained and then the hose is rewound into the housing in an inwardly wound state.

By the way, when the hose is rewound into the housing when the fire extinguishing work is completed, the work of winding the hose inward in the housing by putting a hand through the opening of the open front door or the upper door is performed. The opening of the door or the upper door is narrow for rewinding the hose, and there is a problem that it is difficult to rewind the hose. Further, at the time of periodic inspection, the state of the hose stored in the housing is checked by opening the front door or the upper door, but there is a problem that it is difficult to inspect the hose because the opening is narrow.

When rewinding the hose from the front door opening into the housing, the front panel other than the front door becomes an obstacle, making it difficult to see the hose connection port at the bottom of the housing. Since it is necessary to insert the shoulder, the hose must be rewound while inserting the head and shoulder into the front door opening, and the hose must be maintained in a difficult position, which is accompanied by great labor.

Therefore, for the fire hydrant storage box embedded in the observer passage, an opening for inspection is formed on the front surface of the housing of the fire hydrant storage box for hose rewinding work and inspection work, and the opening is conventionally used. It is conceivable to provide an inspection door that doubles as a front panel, similar to the fire hydrant device of.

However, in such a conventional inspection door, since it is formed of a sheet metal having sufficient strength, the weight of the door becomes as heavy as 50 kg, for example, and the work of removing the inspection door at the time of hose rewinding or inspection is performed. The work of installing the inspection door after rewinding or inspection is difficult, and if there are many fire hydrant devices installed, the work load will increase.

An object of the present invention is to provide a fire hydrant device and a fire hydrant facility that reduce the burden of inspection work of a fire hydrant device provided with an inspection door.

[Internal structure of fire hydrant storage box]
9A and 9B are explanatory views showing the internal structure of the fire hydrant storage box, FIG. 9A shows the front surface, and FIG. 9B shows the side surface seen from the YY cross section of FIG. 9A.

As shown in FIG. 9, the inner lower side of the housing 31 in the fire hydrant storage box 30 is a hose storage portion 74, and the hose 76 having a shape-retaining structure is horizontally stacked and wound inward.

The rectangle seen from the plane of the housing 31 has a width of about 1.4 meters and a depth of about 0.35 meters. Therefore, when the hose 76 is internally wound around the hose storage portion 74, the hose 76 is internally wound. The shape is a rounded rectangle consisting of two parallel lines and two semicircles, and the length of one turn of the hose 76 wound inward in the flat rectangular housing 31 is about 3.5 meters, and the hose length is about 3.5 meters. Since the hose requires 30 meters or more, the hose 76 may be wound inward by stacking 9 turns or more.

Here, the hose 76 wound inward in a rectangular shape with rounded corners in the housing 31 is indicated by parallel hose portions 76a and 76c and semicircular hose portions 76b and 76d.

A hose guide structure 80 is provided on the central front surface side of the housing 31 to inwardly deform the parallel line portion 76a on the front surface side of the hose 76 that is internally wound in the housing 31 in a rectangular shape with rounded corners.

In the hose guide structure 80, two guide pipes 80a and 80b using metal pipes are erected on the bottom plate 81, and the hose 76 is wound inward along the guide pipes 80a and 80b of the hose guide structure 80 to form a hose. The parallel wire hose portion 76a on the front side of the 76 is deformed inward to form a shape close to a gourd shape, and this deformation causes a repulsive force to spread outward in the deformed parallel wire hose portion 76a of the hose 76. are doing.

By providing such a hose guide structure 80, in the hose 76 that is vertically wound in the housing 31, the parallel wire hose portion 76a having rounded corners is deformed inward by the hose guide structure 80. As a result, a repulsive force that tries to spread outward is generated, and a force that presses against the inner wall side of the housing 31 is generated, so that even if the parallel wire hose portions 76a and 76c of the hose 76 that are repeatedly wound inward become long. It is possible to surely prevent it from collapsing inward.

Here, in the hose guide structure 80, the parallel wire hose portion 76a on the front side of the hose 76 is deformed inward, and the parallel hose portion 76c on the back side is not deformed inward, but is deformed inward of the parallel wire hose portion 76a. As a result, the force that tends to spread outward as a whole of the hose 76 increases, and it is possible to reliably prevent the parallel hose portion 76c on the back side that has not been deformed inward from collapsing inward.

Further, when the front door 32 and the second upper door 36 or the first upper door 34 are opened and the hose 76 is pulled out to the outside, the hose is pushed out due to the deformation of the semicircular hose portions 76b and 76d of the hose 76. In addition to the force, the parallel wire hose portion 76a of the hose 76 is also deformed inward by the hose guide structure 80 to generate a force to push out the hose 76, so that the pulling force of the hose 76 can be reduced.

A guide pipe 82 is arranged above the hose guide structure 80 so as to surround the inside of the front door opening 33, the first upper door opening 35, and the second upper door opening 37 shown in FIG. 2, and the hose 76 is externally arranged. By sliding contact with the guide pipe 82 when pulling out the hose, the hose 76 is prevented from being worn and the hose pulling force is reduced.

A foam nozzle 78 connected to the tip of the hose 76 by a nozzle holder 86 is detachably locked on the back surface of the second upper door 36. The nozzle holder 86 of the present embodiment is locked by a suspension structure in which the foam nozzle 78 is pivotally supported on the back surface of the second upper door 36 and suspended in a suspended state, and the second upper door 36 is locked by the second upper door 36 in FIG. The second upper door is also when the upper door 36a is opened forward as shown in the upper door 36a, or when the first upper door 34 is integrally opened with the second upper door 36 as shown in the first upper door 34a of FIG. A nozzle holder 86 is locked to the back surface of the door of 36 in a state where the bubble nozzle 78 is suspended.

Therefore, when the second upper door 36 is opened forward or the first upper door 34 is opened rearward together with the second upper door 36, the foam nozzle 78 held in a suspended state on the back surface of the door appears at the upper part of the fire hydrant storage box 30. become.

The position where the bubble nozzle 78 held on the back surface of the door by opening the front of the second upper door 36 appears is in the range of approximately 0.9 to 1.3 meters from the road 15, which stands on the road 15. Since the foam nozzle 78 appears in front of the user, which corresponds to the range from the waist to the shoulder of the user, the foam nozzle 78 can be easily taken out.

Further, the position where the bubble nozzle 78 held on the back surface of the door when the first upper door 34 is opened rearward appears is in the range of approximately 0.2 to 0.4 meters from the road surface of the observer passage 14, and is monitored. A bubble nozzle 78 appears in front of the user who bends down in the member passage 14 and operates the rear opening handle 40, and the user can easily take out the bubble nozzle 78 from the observer passage 14 side. ..

As shown in FIGS. 10 and 11, the inspection door 100 fixed to the front surface of the housing 31 in the fire hydrant storage box 30 with bolts is the lower side of the inspection door 100 by removing the bolts and releasing the fixed state. The upper side is configured to be opened forward at a predetermined inclination angle θ with the hinge 102 of the above as a rotation axis.

Since the inspection door 100 is fixed to the front surface of the housing 31 with bolts, through holes 108 are formed on both upper sides of the inspection door 100, and screw holes 110 are formed in the frame of the housing 31 facing the through holes 108. ing.

Further, both sides of the inspection door 100 and the frames on both sides of the housing 31 are connected by a chain 104 that functions as a flexible string member, and by determining the length of the chain 104, the hinge 102 is centered. The inclination angle θ of the inspection door 100 when the upper side is opened forward is set.

In the present embodiment, the length of the chain 104 is determined so that the inclination angle θ of the inspection door 100 that is opened forward is, for example, 30 °. Here, assuming that the inclination angle θ = 30 ° and the height of the inspection door 100 is 80 to 90 cm, the distance between the upper end of the front-opened inspection door 100 and the housing 31 is approximately several tens. Even if the front door opening 33 of the inspection door 100 is closed by the front door 32, the distance between the upper end of the front-opened inspection door 100 and the housing 31 is sufficient, such as several tens of centimeters. A wide opening is formed in the door.

However, when the inspection door 100 is opened forward, the lock by the front opening handle 38 provided on the second upper door 36 of the front door 32 is released, and as shown in FIG. 10, the front opening inspection door 100 is opened. The front door 32 provided is in an open state, and therefore a sufficiently wide opening is formed between the front-opened inspection door 100 and the housing 31.

The inspection door 100 shown in FIGS. 10 and 11 is opened prior to the work of horizontally rewinding the drained hose into the housing 31 after the fire extinguishing work is completed. In the state where the inspection door 100 is opened forward and held at a predetermined inclination angle θ by the chain 104 in this way, the staff member takes the drained hose 76 to the hose storage portion 74 in the housing 31 as shown in FIG. Perform the work of rewinding horizontally.

At this time, the clerk can stand in front of the front-opened inspection door 100 and put his / her hand into the housing 31 from above the front-opened inspection door 100 at an angle to wind the hose inward. When the hose is pulled out from the front door opening 33 and the second upper door opening 37 to the road side as shown in FIG. 8, or as shown in FIG. 8, the hose is pulled from the first upper door opening 35 to the observer passage side. In any case when the hose is pulled out, the operation of rewinding the hose into the housing 31 can be easily performed.

Further, when inspecting the hose with a nozzle stored in the fire hydrant storage box 30, the inspection door 100 is released from the fixed state, and as shown in FIGS. 10 and 11, the inspection door 100 is tilted to the front open state. By doing so, it is possible to easily perform the inspection work of visually checking the state of the hose from the opening between the inspection door 100 opened in front and the housing 31.

Further, a front door 32 is provided on the back surface side of the inspection door 100 so as to be able to slide open and close in the vertical direction, and a door opening / closing mechanism for sliding the front door 32 to open / close by setting the inspection door 100 in an inclined front opening state. Can be easily inspected.

[Modification of the present invention]
(Foam fire hydrant equipment)
The above embodiment takes as an example a foam fire hydrant facility that discharges fire extinguishing foam, but the present invention is not limited to this, and a fire hydrant facility that discharges fire extinguishing water may be used.

(Installation of fire hydrant storage box)
Further, in the above embodiment, the hose guide structures 80a and 80b have a fixed structure, but a hinge may be provided at the contact portion with the bottom plate so that the hose guide structures can rotate about the axis in the forward direction. By rotating the hose guide structures 80a and 80b in the forward direction around the axis during inspection and bringing them into contact with the inspection door, the hose guide structure from the open space to the hose storage portion is eliminated by inclining the inspection door.

As a result, it is possible to take a method of sliding the hose bundles gathered in advance on the inspection door and the hose guide structures 80a and 80b and storing them in the hose storage portion. Further, when the hose is rewound, it is not necessary to pass it over the hose guide 82, so that the rewinding work can be easily performed. At this time, it is preferable that the inclination angle θ can be opened to such an extent that the bundled hose bundles can be stored. Therefore, the inclination angle θ is set so that the chain length is opened so as to satisfy sin θ ≧ S / L when the depth of the bottom plate is S and the height from the bottom plate to the hose guide 82 is L.

Further, although the above embodiment takes a fire hydrant device of a tunnel fire hydrant facility as an example, it may be used for a fire hydrant embedded in a general road. Further, the fire hydrant storage box may be exposed without being embedded. When used in an exposed fire hydrant storage box, it is preferable that the upper door comes to a height of about 1 meter in order to facilitate the opening / closing operation of the upper door and to facilitate the removal of the nozzle. In addition, the fire hydrant storage box of the present application may be installed on two passage surfaces having different heights, or on a surface having a different height on which a person can walk and a wall surface in contact with the surface, such as on a stage such as a gymnasium or a stage and below. May be applied.

(Other)
Further, the inspection door may be opened in the lateral direction by rotating around the left end or the right end of the front surface of the housing instead of inclining to the front surface. As a result, the hose can be stored without any limitation from the front. In the case of this method, a space in front of the fire hydrant is required compared to the method of inclining the front door, but this method can be implemented because the passage of the tunnel is restricted when the hose is stored.

Further, the inspection door / front door may be divided at the center so as to open from the shafts on both sides. Compared with the case of rotating only the left end or the right end as an axis, the force concentrated near the lowest point of the axis is reduced, and the possibility of distortion can be reduced.

Further, the present invention includes appropriate modifications that do not impair its purpose and advantages, and is not limited by the numerical values shown in the above embodiments.
