  An embodiment of a fire hydrant device according to the present invention will be described with reference to FIGS. In the embodiment described below, the fire hydrant device is exemplified as a type in which the fire hose is housed in the housing part in the housing, but the present invention is a discharge inspection device in the housing. The present invention can be applied to any type of fire hydrant apparatus having a connection port, and for example, can be applied to a type in which a fire hose is housed on a reel inside a casing.

  First, the basic configuration of the fire hydrant device 1 will be described.

  As shown in FIG. 1, the fire hydrant apparatus 1 includes a hose housing portion 5 in which a fire hose 4 having a fire extinguishing nozzle 4 a at its tip is housed in its inside, and a fire hose for the fire hose. 4 is provided with a piping system portion 6 provided with a fire hydrant valve 7. The piping system unit 6 is connected to a water supply source (not shown) on the primary side.

  The piping system unit 6 is provided with a maintenance valve 8 on the secondary side of the fire hydrant valve 7. The maintenance valve 8 has a discharge inspection device connection port 8a, and is used by being connected to a discharge inspection device (not shown) at the time of discharge inspection. Specifically, it has a structure as a direction switching valve, and is provided in the piping system section 6 so that the flow path on the secondary side can be switched. In other words, always (including in the event of a fire), the secondary-side flow path functions as a side that leads to the fire-extinguishing hose 4 in the connected state, while the water-flowing side reaches the fire-extinguishing hose 4, while The secondary side flow path is provided so as to function as a switch that switches to the side that reaches the discharge inspection device connected to the discharge inspection device connection port 8a and allows water to flow to the side that reaches the discharge inspection device. Then, in the discharge inspection, the fire hydrant valve 7 is opened, the fire water is actually discharged from the discharge inspection device connected to the maintenance valve 8, and the discharge pressure and the like are measured for inspection. In the case of the present embodiment, the piping system section 6 is provided with an automatic pressure regulating valve 9 on the primary side of the fire hydrant valve 7. That is, it is possible to check whether or not the automatic pressure regulating valve 9 is functioning as specified by measuring the discharge pressure during the discharge check.

  The switching operation of the secondary side flow path in the maintenance valve 8 may be performed separately from the connection of the discharge inspection device (for example, manual switching), but the maintenance valve 8 is connected to the discharge inspection device of the discharge inspection device. It is assumed that it has a mechanism that automatically switches the flow path on the secondary side in conjunction with the attachment and detachment to the port 8a. It is good also as what can switch a flow path to the side which reaches a discharge inspection apparatus. As such a maintenance valve 8, various types of conventionally known types can be used. Specifically, for example, the maintenance valve 8 is a secondary flow path (secondary chamber) side in the valve body. In addition, the discharge inspection device connection port 8a is provided, and the valve body inside the main body is interlocked with the insertion / removal of the discharge inspection device connection port 8a to the discharge inspection device connection port 8a of the discharge inspection device. For example, the maintenance valve 8 may be disposed on the primary flow path (primary chamber) side of the valve body. The discharge inspection device connection port 8a is provided, and the base end side connecting portion of the discharge inspection device automatically switches the secondary flow path in conjunction with the insertion / removal to the discharge inspection device connection port 8a. And there is no valve body inside the body at all times By shutting off the secondary side flow path (secondary chamber) side of the valve body in conjunction with the insertion of the proximal end side connection portion of the discharge inspection device into the discharge inspection device connection port 8a Further, a type having a structure for automatically switching the flow path on the secondary side (a structure for switching from the side leading to the fire hose to the side leading to the discharge inspection device connected to the discharge inspection device connection port 8a) may be adopted. .

  Here, the discharge inspection device connected to the maintenance valve 8 will be briefly described. A conventionally known device can be used as the discharge inspection device. That is, for example, a fire extinguishing nozzle of a fire hydrant apparatus to be inspected is formed of a tubular body formed by a shape retaining hose, etc., and has a base end side connection portion connected to the discharge inspection apparatus connection port 8a of the maintenance valve A pressure gauge for measuring the pressure of the fire-extinguishing water discharged from the fire-extinguishing nozzle connected to the tip-side connecting part It can be used. 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 discharge inspection device, the mechanism corresponding to the mechanism is connected to the discharge inspection device. What is provided in the base end side connection part connected to the opening | mouth 8a can be used.

  Next, a direction changing mechanism unit that can change the orientation of the openings 8a provided on at least two of the outer surfaces of the casing 2, that is, a plurality of different outer surfaces, and the connection port 8a for the discharge inspection device of the maintenance valve 8. explain.

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

  The front opening 2b and the rear opening 2f can be opened and closed by a door. Although various door opening / closing methods can be used, in the case of this embodiment, the front opening 2b can be opened and closed by a rotary opening / closing type front door 2c, and the back opening 2f is a sliding opening / closing. The back door 2g can be opened and closed. FIG. 3 shows a state when the doors are opened. As shown in the figure, the front door 2c can open the front opening 2b by rotating forward (for example, a hinge mechanism is provided on the lower side to rotate in that way). The rear door 2g can open the rear opening 2f by sliding downward (for example, a sliding mechanism is provided on the side to slide as such. be able to).

  Here, in the present embodiment, the front opening 2b and the back opening 2f can be used to draw out the fire hose 4 from any of the above as described above. Correspondingly, in the case of the present embodiment, the hose storage 5 corresponds to the front outlet 5a serving as a drawer outlet when the fire hose 4 is pulled out from the front opening 2b, and the fire hose 4 from the rear opening 2f. It has the back surface outlet 5b used as a drawer opening. Specifically, the hose storage portion 5 is provided on the left and right sides close to the inside of the front plate 2a, extending in the vertical direction, and spaced apart in the width direction so as to form the front lead-out port 5a therebetween. A pair of front side bar-like bodies 5c, 5d and left and right provided close to the inside of the back plate 2e, extending in the vertical direction, and spaced apart in the width direction so as to form the back drawer port 5b therebetween A pair of back side bar-like bodies 5e, 5f, between the front side bar-like body 5c and the back side bar-like body 5e on one of the left and right sides, and between the front side bar-like body 5d and the back side bar-like body 5f on the other side. It is assumed to be composed of a frame-shaped storage body made up of a pair of left and right cross-sectional strip plates 5g, 5h provided so as to be installed between them. Thereby, while having a simple structure, the fire hose 4 can be sufficiently held during storage, and the fire hose 4 can be pulled out from either the front side or the back side during withdrawal.

  And the direction of the discharge inspection device connection port 8a of the maintenance valve 8 can be changed to the piping system section 6, and the discharge inspection device can be connected from either the front opening 2b or the rear opening 2f of the housing 2. As an example of the direction changing mechanism portion, a rotating mechanism portion is provided that allows the maintenance valve 8 main body to be rotatable so that the direction of the discharge inspection apparatus connection port 8a can be changed. In the case of this embodiment, the rotation mechanism unit is a joint member that always connects the primary side and the secondary side of the maintenance valve 8 to the piping system unit 6 and allows the maintenance valve 8 to rotate relative to the piping system unit 6. More specifically, in the case of this embodiment, the maintenance valve 8 is provided as swivel joints 11 and 12 that are connected to the piping system section 6 so as to be rotatable around its central axis.

  In the present embodiment, the piping portion in which the maintenance valve 8 is provided in the piping system section 6 is provided in a straight line along the longitudinal direction of the housing 2, and the maintenance valve 8 is a piping in the longitudinal direction. The part is provided with a discharge inspection device connection port 8a in a direction facing the lateral direction (slightly below). The swivel joints 11 and 12 are provided so as to connect the maintenance valve 8 so as to be rotatable around its central axis with respect to a straight 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 that the direction of the discharge inspection device connection port 8 a can be changed in the lateral direction of the housing 2. Yes. As a result, the discharge inspection device connection port 8a can be directed to the front opening 2b side of the housing 2 and to the opposite back opening 2f side. 1 and 2 show a state in which the discharge inspection device connection port 8a is directed toward the rear opening 2f.

  FIG. 4 is an enlarged view of a connection portion between the maintenance valve 8 and the swivel joints 11 and 12 in a connected state. At all times, the primary side of the maintenance valve 8 is connected to the primary swivel joint 11, and the secondary side of the maintenance valve 8 is connected to the secondary swivel joint 12. These swivel joints 11 and 12 are provided so that the center axes of the swivel joints 11 and 12 are located on the same straight line, and the maintenance valve 8 can be rotated in the forward and reverse directions around the center axis as indicated by arrows in the figure. It has been. In the case of the present embodiment, the maintenance valve 8 is a primary side continuous connection port and a secondary side continuous connection port that are parallel to each other but are not located on the same straight line. . For this reason, the primary side of the maintenance valve 8 is directly connected to the swivel joint 11 on the primary side, but the secondary continuous connection port is connected via an inclined pipe joint 13 (inclined pipe portion 13) for adjusting the shaft. 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 an internal structure of a connection portion between the primary side swivel joint 11 and the piping system section 6. As shown in the figure, the swivel joint 11 includes a fixed tube portion 11a and a rotary tube portion 11b that is supported by the fixed tube portion 11a so as to be rotatable about 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 primary connection port on the primary side of the maintenance valve 8, whereby 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 secondary-side swivel joint 12 has a rotary pipe via an inclined pipe joint 13 for adjusting the axis so that its rotational axis is aligned with the rotational axis of the primary-side swivel joint 11. The part side is connected to the constant 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 for blocking the rotation operation (changing operation) by the rotation mechanism section on either one or both. FIG. 6 shows an example in which a stopper 14 that prevents the rotating operation of the rotary tube portion 11b is provided in the primary swivel joint 11 as such a blocking mechanism portion. The stopper 14 is provided so that its locking portion 14a can be engaged and disengaged with respect to the groove portion 11c provided in the rotary tube portion 11b. As shown in FIG. While allowing the rotation of the rotary tube portion 11b in the detached state, as shown in FIGS. 4B and 4C, the rotation of the rotary tube portion 11b with the locking portion 14a fitted in the groove portion 11c. Is provided to prevent. By providing such a blocking mechanism, it is possible to prevent the maintenance valve 8 from being rotated unnecessarily.

  As described above, the fire hydrant apparatus 1 connects the discharge inspection device to the housing 2 from the outside to the discharge inspection device connection port 8a of the maintenance valve 8 such as the front opening 2b and the rear opening 2f. Are provided in each of the plurality of outer surfaces. In addition, the piping system section 6 can change the direction of the connection port 8a for the discharge inspection device by allowing the maintenance valve 8 to rotate, such as the rotation mechanism section by the swivel joints 11 and 12, for example, on a plurality of outer surfaces. On either side of the provided opening, there is provided a direction changing mechanism that can make the discharge inspection apparatus connection port 8a face.

  Therefore, according to the fire hydrant device 1, the discharge inspection device can be connected to the discharge inspection device connection port 8 a from any of the openings provided on the plurality of outer surfaces of the housing 2. A release 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 to draw out the fire hose 4 to the outside. Of course, an opening used for connecting the discharge inspection device to the maintenance valve 8 and an opening used for pulling out the fire hose 4 to the outside may be provided separately. Further, the opening through which the hose can be drawn out is only one surface, and the inspection opening may be provided on the other surface.

  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 discharge inspection is performed from the front side of the housing 2, traffic regulation on the roadway is required. However, it is assumed that the discharge inspection device can be connected to the maintenance valve 8 from a plurality of different surfaces among the front side, the back side, the upper surface side, and the side surface forming the outer surface of the housing 2, and the discharge inspection is performed on the inspection path. If it can be performed, the work can be performed without traffic restriction on the roadway.

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

  When the fire hydrant device 1 is installed at a position as 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 piping system unit 6 side. It is also good. Although it is necessary to provide a space between the opening on the side surface and the maintenance valve 8, the maintenance valve 8 is rotated laterally by the direction changing mechanism on the opening side on the side surface, and the connection port 8 a for the discharge inspection device. , 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 in the same manner as using the rear opening 2f.

  For example, as shown in FIG. 8, the fire hydrant apparatus 1 may be installed so as to be embedded in the audit road R2 at a position facing the roadway R1. Also in this case, when the discharge inspection is performed from the front side of the housing 2, traffic regulation of the roadway R1 is necessary. However, in the case of the fire hydrant device 1 of the example shown in the figure, the upper surface opening 2h is provided in the upper surface plate 2j of the housing 2. Although the internal structure of the housing 2 is not illustrated, the size and position of the upper surface opening 2h can also be used to connect the discharge inspection device to the discharge inspection device connection port 8a of the maintenance valve 8 from the outside. Formed as an opening. If it is assumed that 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 the traffic regulation of the roadway R1. The upper surface opening 2h is normally closed by the upper surface door 2i.

  In the example shown in FIG. 8, as a difference from the examples shown in FIGS. 1 to 7, the piping portion in which the maintenance valve 8 is provided in the piping system section 6 extends along the lateral direction of the housing 2. The maintenance valve 8 is provided in the horizontal piping portion with the discharge inspection device connection port 8a directed in the vertical direction (slightly below). The swivel joints 11 and 12 are provided to connect the maintenance valve 8 so as to be rotatable around its central axis with respect to a 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 maintenance valve 8 is provided so that the direction of the discharge inspection device connection port 8 a can be changed in the vertical direction of the housing 2. Yes. As a result, the discharge inspection device connection port 8a can be directed to the front opening 2b side and the upper opening 2h side of the housing 2.

  In the example shown in FIG. 8 as well, the piping portion in which the maintenance valve 8 is provided in the piping system portion 6 as in the examples shown in FIGS. It is also possible to use a device that is provided in such a manner 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 discharge inspection device connection port 8a is oriented obliquely downward in the lateral direction as the maintenance valve 8, the discharge inspection device can be connected to the side of the maintenance valve 8 from the upper surface opening 2h. If 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, the discharge inspection device can be removed from the upper surface opening 2g. It 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. When the discharge inspection device is connected from the upper surface opening 2g, it can be easily performed.

  Further, in the example shown in FIG. 8, the upper surface opening 2 h may be used to pull out the fire extinguishing hose 4. In that case, the hose storage part 5 is configured such that a space is formed in which the fire hose 4 can be drawn out of the housing 2 from either the front opening 2b or the upper surface opening 2h. What is necessary is just to set it as the structure provided near the back surface in the housing | casing 2 so that a space may be formed between the part 5 and the front plate 2a of the housing | casing 2, Not only an internal winding type but a reel type etc. It may be a method. At this time, the fire-extinguishing nozzle 4a is positioned so as to be easily gripped from both the front opening 2b and the upper opening 2h, for example, closer to the front plate 2a than the front surface of the hose storage portion 5 in plan view, and intermediate in the vertical direction. It may be provided at a position higher than the 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 hydrant valve. 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 a plurality of outer surfaces of the housing 2. . Accordingly, when the discharge 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 and the discharge inspection is performed, the operation lever 7a is operated from the same opening to operate the fire hydrant valve. 7 can be opened.

  Here, with respect to the operation lever 7a of the fire hydrant valve 7, the operation lever 7a is moved from any of the openings provided on the plurality of outer surfaces of the housing 2 in a direction that is easy for the operator to operate. It is good also as what can be opened. For example, in the example of FIG. 7 (an example where 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 opened. Specifically, although not shown, the valve mechanism portion of the fire hydrant valve 7 is a ball valve, and the ball valve circulates between the primary side and the secondary side in the upright state of the operation lever 7a shown in FIG. If the ball valve opens the flow between the primary side and the secondary side in the state where the operation lever 7 is tilted 90 degrees in the front-rear direction, the fire hydrant valve 7 can be operated as such. be able to.

  Furthermore, the fire hydrant valve 7 may be a valve that can be remotely opened and closed as an electric valve, and the remote control means 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 more according to the number of openings. The remote control means is not necessarily provided at a position inside the casing 2 that can be operated from the opening, and may be provided at a position outside the casing 2.

  Next, regarding the openings provided on the plurality of outer surfaces of the housing 2, in the case of this embodiment, as shown as the front opening 2b, the rear opening 2f, and the upper opening 2h, the discharge inspection device can be used from any of them. Can be connected to the discharge inspection device connection port 8a, and the fire hose 4 can be pulled out. That is, in the case of this embodiment, the fire hydrant apparatus 1 has openings that can be used to draw the fire hose 4 to the outside of the housing 2 on a plurality of outer surfaces of the housing 2.

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

  Here, for example, as shown in FIG. 7, when the fire hydrant device 1 is provided in the tunnel in an arrangement in which the front of the housing 2 is the roadway R <b> 1, the fire occurrence position is immediately before the housing 2. If the vehicle is stopped just before the housing 2 and the fire is extinguished using a device closest to the fire occurrence position, the operation of opening the front door 2c or the fire hose from the front opening 2b In some cases, an operation performed from the front side of the housing 2 such as an operation of pulling out 4 cannot be performed. According to the fire hydrant device 1, the back opening 2 f can be used even in such a case, the back door 2 g is opened from the back side of the housing 2, and the fire hose 4 is pulled out from the back opening 2 f. Can do. That is, an operation necessary for fire extinguishing can be performed from the back side of the housing 2. In this case, if it is assumed that the fire hydrant valve 7 can be opened even if the operation lever 7a of the fire hydrant valve 7 is rotated to the rear opening 2f side, the operator can move forward even from the rear side of the housing 2. By pulling, it is possible to open the fire hydrant valve, and thus it is possible to prevent the operator from mistaking the operation direction of opening the fire hydrant valve 7.

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

  For example, as the direction changing mechanism of the discharge inspection device connection port 8a, the direction of only the portion of the discharge inspection device connection port 8a can be changed in place of the rotation mechanism that enables the entire maintenance valve 8 to rotate. It may be a thing. Specifically, as shown in FIG. 9, the maintenance valve 8 is a maintenance valve that reaches the discharge inspection device connection port 8a while the whole is 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 main body 8 is substantially L-shaped (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 good also as what can change the direction of the connection port 8a for discharge | release inspection apparatuses by rotating the substantially L-shaped pipe part 8b. In this case, the maintenance valve 8 may be rotatable by the swivel joints 11 and 12 as in the example shown in FIGS. That is, the substantially L-shaped tube portion 8b can be rotated about the horizontal axis by the swivel joint 15, and the entire maintenance valve 8 can be rotated about the vertical axis by the swivel joints 11 and 12. Also good.

  Further, for the maintenance valve 8, the secondary side is branched into a side leading to the fire hose 4 and a side leading to the discharge inspection device connection port 8 a, and a joint member having a partition valve on each branched secondary side The joint member may be rotatably provided. That is, as the switching valve capable of switching the secondary-side flow path, the above-described two gate valves may be provided instead of the switching lever 8c.

  The fire hydrant apparatus 1 has been described as being provided with a fire hydrant valve 7, an automatic pressure regulating valve 9, and the like in the piping system unit 6 in the housing 2, but the fire hydrant valve is provided in the piping system unit outside the housing connected to the water supply source. 7. An automatic pressure control valve 9 or the like may be provided. In that case, a mechanical (for example, wire) or electrical (for example, wired or wireless communication) remote operation between the operation lever 7a and the fire hydrant valve 7 is possible. The fire hydrant valve 7 may be opened and closed by an operation of the operation lever 7a or the like.
