The maintenance door 22 is normally closed except for maintenance of the fire hydrant device, and only the fire hydrant door 18 is opened while being kept closed even during fire extinguishing work.

  In FIG. 2, a hose storage space 36 is formed on the left side of the housing 12-1, and a valve storage space 38 is formed on the right side.

  The hose storage space 36 is provided with a hose bucket structure. In the hose bucket structure, a bucket frame 40 having a frame portion that is bent up and down in the horizontal direction by bending a frame pipe is arranged, and a hose storage space is formed inside.

  Two hose guides 42 are positioned in the vertical direction by fixing the U-shaped pipe frame at a position offset to the right side from the center of the bucket frame 40, that is, at a position that is substantially the center in the left-right direction of the door opening 16. A hose outlet 45 is formed as a partition. Further, a hose guide 47 that is formed to project forward is provided below the hose outlet 45.

  The hose guide 42 and the overhanging hose guide 47 that partition and form the hose outlet 45 are broken when the hose 44 is pulled out when the hose 44 is pulled out, or the hose 44 is damaged or broken due to rubbing against the door opening 16. Furthermore, the hose 44 is prevented from being caught by the right end or the left end of the open fire hydrant door 18 and being unable to be pulled out.

  In particular, the overhanging hose guide 47 alleviates the sudden bending of the hose when the hose 44 is pulled out in the left direction, and enables a smooth pull-out.

  A hose 44 is housed inside the hose storage space 36 surrounded by the bucket frame 40 and the inner wall of the housing. Here, a hose connection port 46 is arranged in the lower part of the right valve storage space 38, and after the primary side of the hose 44 is connected to the hose connection port 46, the hose 44 is wound into the hose storage space 36. However, in this case, the hose 44 is wound so that the hose 44 is wound clockwise when viewed from the door opening 16.

That is, the hose 44 connected to the hose connection port 46 is first wound in the direction of the hose storage space 36 along the lower inner wall of the casing 12-1, and is wound from the lower side of the hose storage space 36, so that the first casing It passes along the inner surface of the left side surface and moves upward in the housing. Thereafter, it is wound clockwise in the storage space, and finally the hose tip attached with the nozzle 48 is offset from the center of the bucket frame 40 to the right side to open the door opening 16. The nozzle 48 is taken out from a hose outlet 45 formed by a hose guide 42 attached in the vicinity of the center thereof, and is held in a nozzle holder 50 fixed to the right end of the upper bucket frame 40 so as to be detachable rightward . .

  The nozzle 48 is composed of a water discharge part 48a and a handle 48b. The handle 48b is located below the water discharge part 48a while being held sideways with respect to the nozzle holder 50, and the fire hydrant door 18 is opened. It is held so as to face the center direction of the lower door opening.

When the portion 112a is fed into the upper portion of the hose storage space, there is no hose portion (approximately half a turn around) to be removed from the hose storage space, so that the hose 44 can be shortened and the volume of the hose storage space 36 is reduced. The housing 12 can be thinned.

Further, since the hose winding start portion is sent to the lower side of the hose storage space 36 by right-hand winding, the hose 44 does not slide against the bucket frame 40, and the conventional hose left-hand winding in FIG. There is no need for protection against sliding on 116 , and the structure can be simplified.

  Further, the nozzle 48 at the tip of the hose taken out from the hose outlet 45 after being stored in the hose storage space 36 as being right-handed is detachably mounted on the nozzle holder 50 with the water discharge portion 48a facing sideways, and the water discharge portion 48a is turned sideways. Therefore, the fire hydrant door 18 can be opened and the water discharge part 48a of the nozzle 48 can be removed with the water discharge part 48 facing sideways, and the water is not discharged unless the fire hydrant valve opening / closing lever 64 provided on the fire hydrant valve is operated. Since it is unfamiliar to those who do, the nozzle 48 can be removed with a sense of security because the water outlet is not suitable for itself, and there is a great merit in terms of safety.

  Further, in conjunction with the right-handed storage of the hose 44, the nozzle 48 is arranged on the right side of the hose storage space by holding the ear nozzle holder 50, so that extreme bending of the hose 44 drawn through the hose outlet 45 is suppressed, The hose 44 can be pulled out and stored easily without being damaged.

  Further, since the handle 48b is directed toward the center of the lower door opening with respect to the water discharge part 48 held sideways by the nozzle holder 50, the handle 48b is made conspicuous when the fire hydrant door 18 is opened. Whether it is a right hand or a left hand, the handle can be easily grasped and removed with little discomfort. In order to make the handle 48b of the nozzle 48 more conspicuous, the handle position may be clearly marked with characters such as “nozzle” and “handle”, or the handle portion may be painted with a fluorescent color or the like. Also good.

  In the valve storage space 38 disposed on the right side of the hose storage space 36 provided in the housing 12-1, a water supply valve is connected to a piping system from the fire hydrant connection port to which the piping from the pump facility is connected to the hose connection port 46. 51, a fire hydrant valve, an automatic pressure regulating valve, an automatic drain valve, and a maintenance device are provided. Among these, a name plate 66 is provided corresponding to the fire hydrant valve opening / closing lever 64 provided in the fire hydrant valve, and a fire hydrant valve, an automatic pressure regulating valve, and an automatic drain valve are disposed on the back side of the name plate 66.

  Here, the nozzle 48 mounted on the nozzle holder 50 attached to the right end of the upper bucket frame 40 is disposed near the fire hydrant valve opening / closing lever 64 disposed on the front side of the valve housing space, and the nozzle 48 is taken out. This makes it easy to perform an interrelated operation such as opening a fire hydrant valve. The fire hydrant valve opening / closing lever 64 may be painted with a fluorescent color so as to stand out as in the case of the nozzle 48, or the letter of the lever may be marked out.

  FIG. 3 is a plan view showing the internal structure of FIG. In FIG. 3, the casing 12-1 and the casing 12-2 are fixed by bolts at the connection fixing portion 15. In the hose storage space 36 of the housing 12-1, a bucket frame 40 is arranged in a lateral L shape when viewed from above, and the hose 44 is wound in the hose 44 in a right-handed state in the hose storage space 36 formed between the inner wall and the housing. It is stored in. In the fire extinguisher storage space 39, two fire extinguishers 37 are stored in a position that can be seen from the outside through the viewing window 35 of the fire extinguisher door 32.

  A protruding hose guide 47 is provided below the hose outlet 45 formed by partitioning the pair of hose guides 42 as shown in FIG. The hose guide 47 secures an overhanging space having a width substantially corresponding to the outer diameter of the hose 44 inside thereof. Of course, the overhang amount of the overhang hose guide 47 projects forward so that it does not hit when the fire hydrant door 18 is closed, and it is better to have a width that allows at least one hose to enter.

  In the case of the present embodiment, the hydrant door 18 is lightened because a nozzle, a hydrant valve opening / closing lever and a hose guide are not provided as in the prior art, and the door opening is used to absorb the impact when opening. It is only necessary to provide a small shock absorber at the corners on both sides of the lower part of the part 16.

  In the valve storage space 38, a water supply valve 52, a fire hydrant valve 54, an automatic pressure regulating valve 56, and a maintenance device 60 are continuously arranged in the vertical direction. The automatic drain valve 58 is mounted on the secondary side of the fire hydrant valve 54.

  A fire hydrant valve opening / closing lever 64 is directly attached to the fire hydrant valve 54. That is, when the fire hydrant valve opening / closing lever 64 is in the closed position in the upward direction shown in the figure, the fire hydrant valve 54 is closed. At this time, there is no fire water in the pipe and there is no pressure, so the automatic drain valve 58 is open. It is in.

  When the fire hydrant valve opening / closing lever 64 is operated to the open position that faces downward, the fire hydrant valve 54 is operated to the open position, the pressure rises in the pipe, and the automatic drain valve 58 is operated to the closed position. As a result, the fire-extinguishing water pressurized from the water supply connection port 51 is regulated to a predetermined pressure through the automatic pressure regulating valve 56 and then supplied to the hose 44 side.

  At the same time, a switch installed behind the fire hydrant valve opening / closing lever 64 is turned on, whereby a signal is sent to the pump equipment and the pump equipment is started. When stopping the water discharge, returning the hydrant valve opening / closing lever 64 to the original upward position closes the hydrant valve 54 and simultaneously turns off the switch to stop the operation of the pump equipment.

  As described above, in the present embodiment, the fire hydrant valve opening / closing lever 64 that is conventionally provided on the fire hydrant door and opens and closes the fire hydrant valve by wire connection is disposed on the housing 12 side and provided directly on the fire hydrant valve 54.
