The pair of front side rod-shaped bodies 5c and 5d and the left and right which are close to the inside of the back plate 2e and which extend in the vertical direction and are separated from each other in the width direction so as to form the back outlet 5b therebetween. Between the pair of back side rod-shaped bodies 5e and 5f, between the front side rod-shaped body 5c and the back side rod-shaped body 5e on one side, and between the front side rod-shaped body 5d and the back side rod-shaped body 5f on the other side. It is assumed to be composed of a frame-shaped storage body composed of a pair of left and right strip plates 5g and 5h having a substantially U-shaped cross section, which are provided so as to be installed between and. With this structure, the fire extinguishing hose 4 can be sufficiently held at the time of storage while having a simple structure, and the fire extinguishing hose 4 can be pulled out from both the front side and the back side at the time of pulling out.

Further, the direction of the discharge inspection device connection port 8a of the maintenance valve 8 can be changed to the piping system portion 6, and the discharge inspection device can be connected from both the front opening 2b and the rear opening 2f of the housing 2. As an example of the direction changing mechanism section, a rotation mechanism section that allows the maintenance valve 8 main body to rotate and to change the direction of the discharge inspection device connection port 8a is provided. In the case of the present embodiment, the rotation mechanism portion is a joint member that constantly connects the primary side and the secondary side of the maintenance valve 8 to the piping system portion 6 and allows the maintenance valve 8 to rotate with respect to the piping system portion 6. In the present embodiment, the maintenance valve 8 is provided as swivel joints 11 and 12 that rotatably connect the maintenance valve 8 about its central axis.

In the present embodiment, in the piping system portion 6, the piping portion provided with the maintenance valve 8 is provided linearly along the vertical direction of the housing 2, and the maintenance valve 8 is provided with the piping in the vertical direction. The discharge inspection device connection port 8a is provided in the portion in a direction oriented in the lateral direction (slightly downward). The swivel joints 11 and 12 are provided so as to rotatably connect the maintenance valve 8 around the central axis of a linear pipe portion along the vertical direction. That is, the maintenance valve 8 is provided so as to be rotatable in the lateral direction of the housing 2, and the maintenance valve 8 is provided so as to be able to change the direction of the discharge inspection device connection port 8 a in the lateral direction of the housing 2. There is. Thereby, the discharge inspection device connection port 8a can be directed toward the front opening 2b side of the housing 2 and the opposite rear opening 2f side. 1 and 2 show a state in which the discharge inspection device connection port 8a is directed to the rear opening 2f side.

FIG. 4 is an enlarged view of a connection portion between the maintenance valve 8 and the swivel joints 11 and 12 in the connected state. At all times, the primary side of the maintenance valve 8 is connected to the primary side swivel joint 11, and the secondary side of the maintenance valve 8 is connected to the secondary side swivel joint 12. These swivel joints 11 and 12 are provided so that their central axes are located on the same straight line, and the maintenance valve 8 is rotatable about the central axes in the forward and reverse directions as indicated by arrows in the figure. Has been. In the case of the present embodiment, as the maintenance valve 8, a primary side constant connection port and a secondary side constant connection port, whose central axes are parallel to each other but are not located on the same straight line, are used. .. Therefore, the primary side of the maintenance valve 8 is directly connected to the swivel joint 11 on the primary side, but the permanent connection port on the secondary side is provided with the inclined pipe joint 13 (inclined pipe portion 13) for axis adjustment. The swivel joints 12 on the secondary side are connected to each other, so that the central axes of the swivel joints 11 and 12 are located on the same straight line.

FIG. 5 is a cross-sectional view schematically showing the internal structure of the connection part of the primary side swivel joint 11 with the piping system section 6. As shown in the figure, the swivel joint 11 includes a fixed pipe portion 11a and a rotary pipe portion 11b rotatably supported by the fixed pipe portion 11a around a central axis. The fixed pipe part 11a is connected to the piping system part 6 side, and the rotary pipe part 11b is connected to the permanent connection port on the primary side of the maintenance valve 8 so that the primary side of the maintenance valve 8 is connected to the piping system part 6. It is connected so as to be rotatable around the central axis. The secondary swivel joint 12 also has a similar structure, although not shown. However, as described above, the swivel joint 12 on the secondary side is rotated through the inclined pipe joint 13 for axial adjustment in order to align its rotation axis with the rotation axis of the swivel joint 11 on the primary side. The side of the maintenance valve 8 is connected to the permanent connection port on the secondary side of the maintenance valve 8.

The swivel joints 11 and 12 may be provided with a blocking mechanism section that blocks a rotating operation (changing operation) by the rotating mechanism section on either one or both sides. FIG. 6 shows an example in which a stopper 14 for blocking the rotational movement of the rotary tube portion 11b is provided on the primary side swivel joint 11 as such a blocking mechanism portion. The stopper 14 is provided such that the engaging portion 14a thereof can be engaged with and disengaged from the groove portion 11c provided in the rotary tube portion 11b. As shown in FIG. While allowing the rotation tube portion 11b to rotate in the disengaged state, the rotation tube portion 11b rotates while the locking portion 14a is fitted in the groove portion 11c, as shown in FIGS. It is provided to prevent. By providing such a blocking mechanism portion, it is possible to prevent the maintenance valve 8 from being rotated unnecessarily.

As described above, in the fire hydrant device 1, a discharge inspection device is externally connected to the discharge inspection device connection port 8a of the maintenance valve 8 in the housing 2, such as the front opening 2b and the rear opening 2f. An opening sized and positioned for use in each of the plurality of outer surfaces. Further, in the piping system portion 6, like the rotation mechanism portion by the swivel joints 11 and 12, for example, the maintenance valve 8 can be rotated and the direction of the discharge inspection device connection port 8a can be changed, and a plurality of outer surfaces can be provided. A direction changing mechanism portion that can direct the discharge inspection device connection port 8a is provided on either side of the provided opening.

Therefore, according to the fire hydrant device 1, the discharge inspection device can be connected to the discharge inspection device connection port 8a from any of the openings provided on the plurality of outer surfaces of the housing 2, and the plurality of outer surface sides of the housing 2 can be connected. From this, a discharge inspection device can be connected to the maintenance valve 8.

In the case of the present embodiment, the openings provided on the plurality of outer surfaces of the housing 2 used for connecting the discharge inspection device to the maintenance valve 8 are also used for drawing out the fire extinguishing hose 4 to the outside. However, of course, the opening used for connecting the discharge inspection device to the maintenance valve 8 and the opening used for pulling out the fire-extinguishing hose 4 may be separately provided. Further, the opening through which the hose can be drawn out is only one surface, and the opening for inspection may be provided on the other surface.

Here, as the placement of the fire hydrant device 1 in the tunnel, the front of the housing 2 may immediately become the roadway. In that case, if the discharge inspection is performed from the front side of the housing 2, traffic regulation on the roadway is required. However, the discharge inspection device can be connected to the maintenance valve 8 from a plurality of different surface sides of the front surface, the back surface side, the upper surface side and the side surface forming the outer surface of the housing 2, and the discharge inspection can be performed on the inspection road. If it is possible to do so, the work can be done without traffic restrictions on the roadway.

Specifically, for example, as shown in FIG. 7, the fire hydrant device 1 is installed at a position near the road R1 on the inspection road R2 between the tunnel inner wall W and the road R1, and the front of the casing 2 is the road. It may be R1. In this case, if the emission inspection is performed from the front side of the housing 2, traffic regulation of the road R1 is required, but as in the present embodiment, the emission inspection device is maintained from the rear opening 2f on the rear side of the housing 2. If it can be connected to the valve 8, the work of discharge inspection can be performed on the inspection path R2. That is, the discharge inspection can be performed without traffic regulation on the road R1.

When the fire hydrant device 1 is installed at the position shown in FIG. 7, an opening that can be used to connect the discharge inspection device to the maintenance valve 8 is provided on the side surface of the casing 2 on the side of the piping system unit 6. It may be good. It is necessary to provide a space between the opening on the side surface side and the maintenance valve 8, but the maintenance valve 8 is laterally rotated by the direction changing mechanism on the opening side on the side surface side and the connection port 8a for the discharge inspection device is provided. The discharge inspection device can be connected to the maintenance valve 8 through the opening on the side surface, and the discharge inspection work can be performed on the inspection path R2 as in the case of using the rear opening 2f.

Further, for example, as shown in FIG. 8, the fire hydrant device 1 may be installed so as to be embedded in the inspection road R2 at a position facing the road R1. Also in this case, when the discharge inspection is performed from the front side of the housing 2, traffic regulation on the road R1 is required. However, in the case of the fire hydrant device 1 of the example shown in the figure, it is assumed that the top plate 2j of the housing 2 is provided with the top opening 2h. Although the internal structure of the housing 2 is not shown, the upper surface opening 2h is also a size and a position that can be used for externally connecting the discharge inspection device to the discharge inspection device connection port 8a of the maintenance valve 8. Formed as an opening. If the discharge inspection device can be connected to the maintenance valve 8 also from the upper surface opening 2h, the discharge inspection work can be performed on the inspection path R2. That is, also in this case, the discharge inspection can be performed without traffic regulation of the road R1. The upper surface opening 2h is normally closed by the upper surface door 2i.

In the example shown in FIG. 8, the difference from the examples shown in FIGS. 1 to 7 is that the pipe portion of the pipe system portion 6 in which the maintenance valve 8 is provided extends along the lateral direction of the housing 2. The maintenance valve 8 is provided in a lateral pipe portion with the discharge inspection device connection port 8a oriented vertically (slightly downward). The swivel joints 11 and 12 are provided so as to rotatably connect the maintenance valve 8 around the central axis of the linear pipe portion along the lateral direction. That is, the maintenance valve 8 is provided so as to be rotatable in the vertical direction of the housing 2, and the orientation of the discharge inspection device connection port 8 a is provided so as to be changed in the vertical direction of the housing 2. There is. As a result, the discharge inspection device connection port 8a can be made to face both the front opening 2b side and the top opening 2h side of the housing 2.

In the example shown in FIG. 8 as well, as in the example shown in FIGS. 1 to 7, in the piping system portion 6, the piping portion provided with the maintenance valve 8 is arranged along the vertical direction of the housing 2. It is also possible to use a device that is provided linearly and that is provided so that the direction of the discharge inspection device connection port 8a can be changed to the lateral direction of the housing 2. That is, even when the maintenance valve 8 has the discharge inspection device connection port 8a directed obliquely downward in the lateral direction, the discharge inspection device can be connected to the side of the maintenance valve 8 from the upper surface opening 2h. If a space is provided, the maintenance valve 8 is rotated laterally by the swivel joints 11 and 12, and the discharge inspection device connection port 8a is directed in the direction of the space, so that the discharge inspection device is opened from the top opening 2g. Can be connected. However, the maintenance valve 8 may be one in which the discharge inspection device connection port 8a is directed obliquely upward in the lateral direction. If the discharge inspection device is connected through the upper surface opening 2g, the work can be performed more easily.

Further, in the example shown in FIG. 8, the upper surface opening 2h may be used to pull out the fire-extinguishing hose 4. In that case, the hose housing portion 5 is configured to have a space in which the fire extinguishing hose 4 can be drawn out of the housing 2 from both the front opening 2b and the upper surface opening 2h. It may be configured such that a space is formed between the portion 5 and the front plate 2a of the housing 2, and the structure may be provided near the back surface in the housing 2, and the invention is not limited to the inner winding type and other types such as a reel type. It may be a system. At this time, the fire extinguishing nozzle 4a is located at a position where it can be easily grasped from both the front opening 2b and the top opening 2h, for example, in the plan view, closer to the front plate 2a than the front surface of the hose storage portion 5, and vertically intermediate. It is better to be provided at a position above.

The fire hydrant device 1 of the present embodiment will be further described.

The fire hydrant valve 7 is provided with a manual operation lever 7a for opening and closing the fire hydrant valve 7. The operation lever 7a is provided at a position that can be opened and closed from any of the openings (the front opening 2b and the back opening 2f or the front opening 2b and the top opening 2h) provided on the plurality of outer surfaces of the housing 2. .. Accordingly, when the discharge inspection device is connected to the maintenance valve 8 through any of the openings provided on the outer surfaces of the housing 2 to perform the discharge inspection, the operation lever 7a is operated from the same opening to operate the fire hydrant valve. 7 can be opened.

Here, as for the operation lever 7a of the fire hydrant valve 7, the fire hydrant valve 7 is moved by moving the operation lever 7a from any of the openings provided on the plurality of outer surfaces of the housing 2 in a direction in which the operator can easily operate. The opening operation may be possible. For example, in the example of FIG. 7 (example in which the front opening 2b and the rear opening 2f are provided), even if the operator rotates the operation lever 7a toward the front opening 2b, the operation lever 7a is rotated toward the rear opening 2f. Alternatively, the fire hydrant valve 7 may be operable. Specifically, although not shown, the valve mechanism of the fire hydrant valve 7 is a ball valve, and when the operation lever 7a shown in FIG. 1 is in the upright state, the ball valve prevents the flow between the primary side and the secondary side. If the ball valve opens the flow between the primary side and the secondary side in the state where it is shut off and the operating lever 7 is tilted 90 degrees in the front-rear direction, the fire hydrant valve 7 can be operated in that way. be able to.

Further, the fire hydrant valve 7 may be a valve that can be remotely opened and closed by using it as an electrically operated valve, and its remote operation means can be operated at a position that can be operated from any of the openings provided on the plurality of outer surfaces of the housing 2. You may make it provide one or multiple according to the number of openings. The remote control means does not necessarily have to be provided at a position inside the housing 2 that can be operated from the opening, but may be provided at a position outside the housing 2.

Next, regarding the openings provided on the plurality of outer surfaces of the housing 2, in the case of the present embodiment, as shown as the front opening 2b, the rear opening 2f, and the upper surface opening 2h, the discharge inspection device from any of them. Not only can be connected to the discharge inspection device connection port 8a, but also the fire extinguishing hose 4 can be pulled out to the outside. That is, in the case of the present embodiment, the fire hydrant device 1 has openings on the outer surfaces of the housing 2 that can be used to draw out the fire hoses 4 to the outside of the housing 2.

Since the fire hydrant device 1 has openings that can be used to draw out the fire hoses 4 to the outside of the housing 2 on a plurality of outer surfaces of the housing 2, the openings to be used can be appropriately selected. For example, the opening to be used can be appropriately selected according to various conditions at the time of extinguishing the fire such as the positional relationship with the fire occurrence position.

Here, for example, when the fire hydrant device 1 is provided in a tunnel in a layout such that the roadway R1 is immediately in front of the housing 2 as shown in FIG. The vehicle may stop immediately before the housing 2, and when the fire is extinguished by using the device closest to the fire occurrence position, the operation of opening the front door 2c or the fire hose from the front opening 2b is performed. There may be a case where an operation performed from the front surface side of the housing 2 such as an operation of pulling out 4 cannot be performed. According to the fire hydrant device 1, the rear opening 2f can be used even in such a case, and the rear door 2g can be opened from the rear side of the housing 2 and the fire extinguishing hose 4 can be pulled out from the rear opening 2f. You can That is, the operation necessary for extinguishing the fire can be performed from the back side of the housing 2.
