You can use what you have. If the maintenance valve 8 has a mechanism that automatically switches the flow path on the secondary side in conjunction with the attachment / detachment of the release inspection device, a mechanism corresponding to that mechanism is connected to the release inspection device. Those provided in the base end side connection portion connected to the port 8a can be used.

Next, regarding the opening provided on at least two of the outer surfaces of the housing 2, that is, a plurality of different outer surfaces, and the direction changing mechanism portion that enables the direction of the connection port 8a for the discharge inspection device of the maintenance valve 8 to be changed. explain.

As shown in FIG. 1, the housing 2 is provided with a front opening 2b in a front plate 2a forming an outer surface on the front side thereof. The front opening 2b can be used to pull out the fire extinguishing hose 4 stored in the hose storage portion 5 to the outside, and the discharge inspection device is connected to the connection port 8a for the release inspection device of the maintenance valve 8 from the outside. It is formed as an opening of a size and position that can be used to. Further, as shown in FIG. 2, the housing 2 is further provided with a back opening 2f in the back plate 2e forming the outer surface on the back side thereof. This rear opening 2f can also be used to pull out the fire extinguishing hose 4 stored in the hose storage portion 5 to the outside, and also connect the discharge inspection device from the outside to the connection port 8a for the release inspection device of the maintenance valve 8. It is formed as an opening of a size and position that can be used to. That is, the housing 2 can be used as a front opening 2b and a back opening 2f to pull out the fire extinguishing hose 4 stored in the hose storage portion 5 to the outside, and is used for a release inspection device for the maintenance valve 8. Openings of a size and position that can be used to connect the emission inspection device from the outside to the connection port 8a are provided on both the front side and the back side.

Both the front opening 2b and the back opening 2f can be opened and closed by the door. Various door opening / closing methods can be used, but in the case of the present embodiment, the front opening 2b can be opened / closed by the rotary opening / closing type front door 2c, and the back opening 2f can be opened / closed by sliding. It can be opened and closed by the type rear door 2g. FIG. 3 shows the state when those doors are opened.

The rear door 2g can be slid downward to open the rear opening 2f (for example, a slide mechanism is provided on the side side so that the rear door 2g can be slid in such a manner). be able to).

Here, in the present embodiment, the front opening 2b and the back opening 2f can be used to pull out the fire extinguishing hose 4 from either of them as described above. Correspondingly, in the case of the present embodiment, the hose storage portion 5 has a front drawer port 5a which is a drawer port when the fire extinguishing hose 4 is pulled out from the front opening 2b and a fire extinguishing hose 4 when the fire extinguishing hose 4 is pulled out from the rear opening 2f. It is assumed that it has a back drawer port 5b that serves as a drawer port for the hose. Specifically, the hose storage portions 5 are provided close to the inside of the front plate 2a, extend in the vertical direction, and are separated in the width direction so as to form the front outlet 5a in between. The pair of front side rods 5c and 5d and the left and right sides that are close to the inside of the back plate 2e, extend in the vertical direction, and are separated in the width direction so as to form the back outlet 5b in between. A pair of back side rods 5e and 5f, between the front side rods 5c and the back side rods 5e on one of the left and right sides, and the front side rods 5d and the back side rods 5f on the other side. It is composed of a frame-shaped storage body consisting of a pair of left and right strips having a substantially U-shaped cross section, 5g and 5h, which are provided so as to be erected between them. As a result, although the structure is simple, the fire extinguishing hose 4 can be sufficiently held at the time of storage, and the fire extinguishing hose 4 can be pulled out from either the front side or the back side at the time of withdrawal.

Then, the direction of the discharge inspection device connection port 8a of the maintenance valve 8 can be changed to the piping system unit 6, and the release inspection device can be connected from either the front opening 2b or the back opening 2f of the housing 2. As an example of the direction change mechanism unit, a rotation mechanism unit is provided so that the maintenance valve 8 main body can be rotated and the direction of the discharge inspection device connection port 8a can be changed. 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 makes the maintenance valve 8 rotatable with respect to the piping system portion 6. Specifically, in the case of the present embodiment, the maintenance valve 8 is provided as swivel joints 11 and 12 for rotatably connecting the maintenance valve 8 to the piping system portion 6 around 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 the vertical piping thereof. The discharge inspection device connection port 8a is provided in the portion so as to face laterally (slightly diagonally downward). The swivel joints 11 and 12 are provided to rotatably connect the maintenance valve 8 around the central axis to the linear piping portion along the vertical direction thereof. That is, the maintenance valve 8 is provided so as to be rotatable in the lateral direction of the housing 2, and the direction of the connection port 8a for the discharge inspection device can be changed in the lateral direction of the housing 2. There is. As a result, the connection port 8a for the discharge inspection device can be directed to both the front opening 2b side of the housing 2 and the back opening 2f side on the opposite side. Note that FIGS. 1 and 2 show a state in which the connection port 8a for the discharge inspection device is directed toward the rear opening 2f.

FIG. 4 shows an enlarged view of the connection portion between the maintenance valve 8 and the swivel joints 11 and 12 in the connected state. The primary side of the maintenance valve 8 is always connected to the swivel joint 11 on the primary side, and the secondary side of the maintenance valve 8 is connected to the swivel joint 12 on the secondary side. 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 can rotate in the forward and reverse directions around the central axis as shown by an arrow in the figure. Has been done. In the case of the present embodiment, as the maintenance valve 8, a maintenance valve 8 is used in which the central axes of the primary side constant connection port and the secondary side constant connection port are parallel to each other but not located on the same straight line. .. Therefore, the primary side of the maintenance valve 8 is directly connected to the swivel joint 11 on the primary side, but the constant connection port on the secondary side is via the inclined pipe joint 13 (inclined pipe portion 13) for shaft adjustment. It is assumed that it is connected to the swivel joint 12 on the secondary side, whereby 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 portion of the swivel joint 11 on the primary side with the piping system portion 6. As shown in the figure, the swivel joint 11 includes a fixed pipe portion 11a and a rotating pipe portion 11b rotatably supported by the fixed pipe portion 11a around a central axis. The fixed pipe portion 11a is connected to the piping system portion 6 side, and the rotary pipe portion 11b is connected to the constant 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 portion 6. It is rotatably connected around the central axis. The swivel joint 12 on the secondary side also has a similar structure, although not shown. However, as described above, the swivel joint 12 on the secondary side is a rotary pipe via the inclined pipe joint 13 for shaft adjustment in order to align the rotation axis with the rotation axis of the swivel joint 11 on the primary side in the same linear shape. The part side is connected to the constant connection port on the secondary side of the maintenance valve 8.

In addition, the swivel joints 11 and 12 may be provided with a blocking mechanism portion for blocking the rotation operation (changing operation) by the rotation mechanism portion on either one or both. FIG. 6 shows an example in which a stopper 14 for blocking the rotational operation of the rotary pipe portion 11b is provided on the swivel joint 11 on the primary side as such a blocking mechanism portion. The stopper 14 is provided so that the locking portion 14a can be engaged with and detached from the groove portion 11c provided in the rotary pipe portion 11b, and the locking portion 14a is provided from the groove portion 11c as shown in FIG. While allowing the rotation of the rotary tube portion 11b in the detached state, as shown in FIGS. (B) and (c), the rotation of the rotary tube portion 11b in the state where the locking portion 14a is fitted in the groove portion 11c. It is provided to prevent. By providing such a blocking mechanism portion, it is possible to prevent the maintenance valve 8 from being unnecessarily rotated.

As described above, the fire hydrant device 1 connects the discharge inspection device to the housing 2 from the outside to the connection port 8a for the release inspection device of the maintenance valve 8, for example, the front opening 2b and the back opening 2f. There are openings of sizes and positions that can be used for each of the plurality of outer surfaces. Further, in the piping system portion 6, for example, like the rotation mechanism portion by the swivel joints 11 and 12, the maintenance valve 8 can be rotated and the direction of the connection port 8a for the discharge inspection device can be changed, and the direction of the connection port 8a for the discharge inspection device can be changed to a plurality of outer surfaces. A direction changing mechanism portion capable of directing the discharge inspection device connection port 8a is provided on any 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 release inspection device can be connected to the plurality of outer surface sides of the housing 2. A release inspection device can be connected to the maintenance valve 8 from the above.

In the case of the present embodiment, the openings provided on the plurality of outer surfaces of the housing 2 used to connect the release inspection device to the maintenance valve 8 are also used to pull out the fire extinguishing hose 4 to the outside. Of course, the opening used to connect the discharge inspection device to the maintenance valve 8 and the opening used to pull out the fire extinguishing hose 4 to the outside may be provided separately. Further, the hose can be pulled out from only one side, and an opening for inspection may be provided on the other side.

Here, as the arrangement of the fire hydrant device 1 in the tunnel, the front of the housing 2 may immediately become a roadway. In that case, if the release inspection is performed from the front side of the housing 2, traffic regulation on the roadway is required. However, it is assumed that the release inspection device can be connected to the maintenance valve 8 from a plurality of different surface sides of the front side, the back side, the upper surface side, and the side surface side forming the outer surface of the housing 2, and the release inspection device can be connected to the maintenance valve 8. If it can be done, 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 closer to the roadway R1 on the inspection road R2 between the tunnel inner wall W and the roadway R1, and immediately before the housing 2 is the roadway. It may be R1. In this case, if the release inspection is performed from the front side of the housing 2, traffic regulation of the roadway R1 is required. However, as in the present embodiment, the release inspection device is maintained from the back opening 2f on the back side of the housing 2. If it can be connected to the valve 8, the release inspection work can be performed on the audit path R2. That is, the release inspection can be performed without the traffic regulation of the roadway 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 housing 2 on the piping system portion 6 side. It may be used as a fire hydrant. 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 rotated laterally 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 used. The release inspection device can be connected to the maintenance valve 8 from the opening on the side surface side thereof, and the release inspection work can be performed on the inspection path R2 in the same manner as when the rear opening 2f is used.

Further, for example, as shown in FIG. 8, the fire hydrant device 1 may be installed so as to be embedded in the audit path R2 at a position facing the roadway R1. In this case as well, if the emission inspection is performed from the front side of the housing 2, traffic regulation on the roadway 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 upper surface plate 2j of the housing 2 is provided with the upper surface opening 2h. Although the internal structure of the housing 2 is not shown, the size and position of the upper surface opening 2h can also be used to connect the discharge inspection device from the outside to the connection port 8a for the release inspection device of the maintenance valve 8. Formed as an opening in. If the discharge inspection device can be connected to the maintenance valve 8 from the upper surface opening 2h, the discharge inspection work can also be performed on the audit path R2. That is, even in this case, the release inspection can be performed without the traffic regulation of the roadway R1. The upper surface opening 2h is always 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 piping portion provided with the maintenance valve 8 in the piping system portion 6 is along the lateral direction of the housing 2. The maintenance valve 8 is provided in a straight line, and the maintenance valve 8 is provided in a piping portion in the lateral direction thereof with the discharge inspection device connection port 8a facing in the vertical direction (slightly diagonally downward). The swivel joints 11 and 12 are provided to rotatably connect the maintenance valve 8 around the central axis to the linear piping portion along the lateral direction thereof. That is, the maintenance valve 8 is provided so as to be rotatable in the vertical direction of the housing 2, and the direction of the connection port 8a for the discharge inspection device can be changed in the vertical direction of the housing 2. There is. As a result, the connection port 8a for the discharge inspection device can be directed to both the front opening 2b side and the upper surface opening 2h side of the housing 2.

Also in the example shown in FIG. 8, the piping portion provided with the maintenance valve 8 in the piping system portion 6 as in the examples shown in FIGS. 1 to 7 is along the vertical direction of the housing 2. It is also possible to use a device that is provided in a straight line and is provided so that the direction of the connection port 8a for the discharge inspection device can be changed in the lateral direction of the housing 2. That is, even when the maintenance valve 8 is used with the discharge inspection device connection port 8a directed diagonally downward in the lateral direction, the release 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 release inspection device can be installed from the upper surface opening 2g. It can be connected. However, as the maintenance valve 8, a connection port 8a for a discharge inspection device may be used with the connection port 8a directed diagonally upward in the lateral direction. When connecting the discharge inspection device from the upper surface opening 2 g, 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 storage portion 5 is configured such that a space is formed so that the fire extinguishing hose 4 can be pulled out from both the front opening 2b and the top opening 2h to the outside of the housing 2, for example, the hose storage. The configuration may be provided near the back surface in the housing 2 so that a space is formed between the portion 5 and the front plate 2a of the housing 2, and the configuration is not limited to the inward winding type, but other types such as a reel type. It may be a method. At this time, the fire extinguishing nozzle 4a is located at a position where it can be easily grasped from either the front opening 2b or the upper surface opening 2h, for example, in a plan view, the fire extinguishing nozzle 4a is closer to the front plate 2a than the front surface of the hose storage portion 5 and is intermediate in the vertical direction. It is preferable that the hose is provided at a position above the hose.

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 where it can be opened and closed from any of the openings (front opening 2b and back opening 2f or front opening 2b and top opening 2h, etc.) provided on the plurality of outer surfaces of the housing 2. .. As a result, when the release inspection device is connected to the maintenance valve 8 from any of the openings provided on the plurality of outer surfaces of the housing 2 to perform the release inspection, the operation lever 7a is operated from the same opening to extinguish the fire hydrant valve. 7 can be opened.

Here, regarding the operation lever 7a of the fire hydrant valve 7, the fire hydrant valve 7 is moved in a direction that is easy for the operator to operate from any of the openings provided on the plurality of outer surfaces of the housing 2. It may be open-operated. For example, in the example of FIG. 7 (an example in which the front opening 2b and the back opening 2f are provided), even if the operator rotates the operation lever 7a toward the front opening 2b side, the operation lever 7a is rotated toward the back opening 2f side. Also, the fire hydrant valve 7 may be openable. Specifically, although not shown, the valve mechanism of the fire hydrant valve 7 is a ball valve, and in the upright state of the operating lever 7a shown in FIG. 1, the ball valve flows between the primary side and the secondary side. If the ball valve opens the flow between the primary side and the secondary side when the operation lever 7 is turned off by 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 remotely controlled by using it as an electric valve, and the remote control means may be operated at a position where it can be operated from any of the openings provided on the plurality of outer surfaces of the housing 2. One may be provided or a plurality may be provided depending on 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, and 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 back opening 2f, and the upper surface opening 2h, the release inspection device is provided from any of them. Can be connected to the connection port 8a for the discharge inspection device, and 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 an opening on a plurality of outer surfaces of the housing 2 that can be used to pull out the fire extinguishing hose 4 to the outside of the housing 2.

Since the fire hydrant device 1 has an opening on a plurality of outer surfaces of the housing 2 that can be used to pull out the fire extinguishing hose 4 to the outside of the housing 2, the opening 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 position where the fire occurs.

Here, for example, when the fire hydrant device 1 is provided in the tunnel so that the front of the housing 2 is the road R1 as shown in FIG. 7, the position where the fire occurs is immediately before the housing 2. If the vehicle may be stopped just before the housing 2 and the fire is extinguished using the device closest to the position where the fire occurred, the operation to open the front door 2c or the fire extinguishing hose from the front opening 2b It may not be possible to perform operations such as pulling out 4 from the front side of the housing 2. According to the fire hydrant device 1, the back opening 2f can be used even in such a case, the back door 2g is opened from the back side of the housing 2, and the fire extinguishing hose 4 is pulled out from the back opening 2f. Can be done. That is, the operation necessary for extinguishing the fire can be performed from the back side of the housing 2. In this case, if the fire hydrant valve 7 can be opened even if the operation lever 7a of the fire hydrant valve 7 is rotated toward the back opening 2f side, the operator can open the fire hydrant valve 7 even from the back side of the housing 2. It is possible to open the fire hydrant valve by pulling it, thereby preventing the operator from making a mistake in the operation direction of opening the fire hydrant valve 7.

Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the above-described embodiments, and the configuration can be appropriately changed within the scope of the gist of the invention.

For example, as the direction changing mechanism portion of the discharge inspection device connection port 8a, the direction of only the portion of the release inspection device connection port 8a can be changed instead of the rotation mechanism portion that makes the entire maintenance valve 8 rotatable. It may be a thing. Specifically, as the maintenance valve 8, as shown in FIG. 9, the maintenance valve leading to the connection port 8a for the discharge inspection device is used as a switching valve that can switch the flow path on the secondary side by the switching lever 8c. The pipe portion 8b extending from the 8 main body is made to have a substantially L-shape (for example, an elbow pipe), and the substantially L-shaped pipe portion 8b is connected to the maintenance valve 8 main body via a joint member 15 such as a swivel joint. It is assumed that the connection port 8b is rotatably connected to the device, and the orientation of the discharge inspection device connection port 8a may be changed by rotating the substantially L-shaped tube portion 8b. In this case, the maintenance valve 8 may be made rotatable by the swivel joints 11 and 12 as in the examples shown in FIGS. 1 to 7. That is, it is assumed that the substantially L-shaped pipe portion 8b can be rotated around the horizontal axis by the swivel joint 15, and the entire maintenance valve 8 can be rotated around the vertical axis by the swivel joints 11 and 12. May be good.

Further, regarding the maintenance valve 8, the secondary side is branched into the side leading to the fire extinguishing hose 4 and the side leading to the connection port 8a for the discharge inspection device, and the joint member having a sluice valve on each of the branched secondary sides. However, the joint member may be provided so as to be rotatable. That is, as a switching valve capable of switching the flow path on the secondary side, the above-mentioned two sluice valves may be provided instead of the switching lever 8c.

The fire hydrant device 1 has been described as having a fire hydrant valve 7, an automatic pressure regulating valve 9, and the like provided in the piping system portion 6 inside the housing 2, but the fire hydrant valve is provided in the piping system portion outside the housing connected to the water supply source. 7. An automatic pressure regulating valve 9 or the like may be provided, in which case a mechanical (for example, wire) or electrical (for example, wired or wireless communication) remote operation is performed between the operation lever 7a and the fire hydrant valve 7. The fire hydrant valve 7 may be opened and closed by operating the operation lever 7a or the like by being connected by means.
