  A fire extinguisher door 32 is provided on the left side of the door opening 17, and the inside of the housing 12 corresponding to the fire extinguisher door 32 is used as a fire extinguisher storage space, for example, containing two fire extinguishers. The fire extinguisher door 32 is provided with a handle 34. When the handle 34 is pulled forward, the latch is released, and the fire extinguisher door 32 can be opened forward with the left side as a hinge. In addition, a viewing window 35 is provided below the fire extinguisher door 34 so that the presence or absence of the fire extinguisher can be confirmed from the outside.

  FIG. 2 is a front view showing the internal structure of the embodiment of FIG. 1 with the fire hydrant door on the first housing 12-1 side removed and the maintenance door 22 opened upward and supported by a stay 27. In FIG. 2, a hose storage space 36 is formed on the left side of the first casing 12-1, and a valve storage space 38 is formed on the right side.

  In the hose storage space 36, a bucket frame 40 having a frame portion that is bent up and down in the horizontal direction by bending a frame pipe is disposed, and the hose storage space 36 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 disposed in the lower portion 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 portion 36 along the lower inner wall of the first housing 12-1 and is wound from the lower side of the hose storage space 36, and thereafter The hose formed by a hose guide 42 attached in the vicinity of the center of the door opening 16 with the tip of the hose that is wound clockwise in the storage space and is finally offset from the center of the bucket frame 40 to the right side. A nozzle 48 is detachably attached to a nozzle holder 50 which is taken out from the outlet 45 and fixed to the right hose guide 42.

  In the hose storage space 36, the hose connection port 46 is positioned at the lowermost position and is housed by a right-handed inner winding. As shown in the conventional example in FIG. 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 hose bucket 42, and the conventional hose left-hand winding in FIG. Therefore, it is not necessary to protect against sliding 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 facing downward, and the water discharge portion is directed downward. Then, the fire hydrant door can be opened and the nozzle 48 can be removed with the water discharge part facing downward, and the water will not be discharged unless the fire hydrant valve opening / closing lever 64 provided on the fire hydrant valve is operated. Since it is unfamiliar, the nozzle 48 can be removed with a sense of security because the water outlet is not suitable for itself, which is a great merit in terms of safety.

  In addition, the nozzle 48 arranged with the water discharge portion facing downward can be easily grasped and removed with almost no sense of incongruity with either the right hand or the left hand.

  Further, in the present embodiment, the hose 44 connected to the hose connection port 46 disposed on the lower side of the valve storage unit 38 is drawn into the hose storage space 36 from the lower side so as to be wound clockwise. When housed in the bucket frame 40, the hose is guided to the hose entrainment start position through the hose holder 90 disposed on the back side of the bottom of the housing.

  That is, the hose holder 90 is a state in which the hose portion between the hose end 44a connected to the hose connection port 46 and the inner winding start position 44b is bent toward the rear side of the casing away from the hose outlet 45 on the front side of the casing. Is holding in.

  By providing the hose holder 90 in this manner, when the hose 44 is pulled rightward from the hose outlet 45, the hose 44 hits the hose guide 42 on the right side of the hose connection port 45 and is bent and crushed. Can be prevented.

  A valve storage space 38 disposed on the right side of the hose storage space 36 provided in the first housing 12-1 has a piping system extending from the hydrant connection port 51 to which the piping from the pump facility is connected to the hose connection port 46.

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.
