  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 in which one frame pipe is bent and arranged vertically is arranged, and a hose storage space is formed inside. The two hose guides 42 are fixed in the vertical direction at a position offset from the center of the bucket frame 40 to the right side, that is, at a substantially central position in the left-right direction of the door opening 16, thereby forming a hose outlet 45. ing.

  The hose guide 42 that partitions and forms the hose outlet 45 prevents the inner hose 44 from collapsing when the hose 44 is pulled out, and prevents the hose 44 from being damaged or broken by rubbing against the door opening 16. Further, the hose 44 is prevented from being caught by the right end or the left end of the open fire hydrant door 18 and cannot be pulled 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 first housing 12-1 and is wound from the lower side of the hose storage space 36. 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 that is taken out from the outlet 45 and attached to the lower bucket frame 40.

  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 bucket frame 40 , and the hose bucket is wound by the conventional left-hand winding of 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 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.

  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. A water supply valve 52, a fire hydrant valve, an automatic pressure regulating valve, an automatic drain valve, and a maintenance device 60 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.

  FIG. 3 is a plan view showing the internal structure of FIG. In FIG. 3, the first housing 12-1 and the second housing 12-2 are fixed by bolts at the connection fixing portion 15. In the hose storage space 36 of the first housing 12-1, a bucket frame 40 is disposed in a lateral L shape when viewed from above, and the hose 44 is wound inside the hose storage space 36 formed between the housing inner wall and the hose 44 by clockwise winding. Stored in a wound state. In addition, two fire extinguishers 37 are housed in the fire extinguisher housing space 39.

In FIG. 4, the fire hydrant door 18 in the closed state of the front surface of the first housing 12-1 can be opened to the illustrated forward position around the hinge 21 by releasing the latch by a handle operation.

  In this case, since the fire hydrant door 18 is not provided with a nozzle, a fire hydrant valve opening / closing lever, and a hose guide as in the prior art, the weight is reduced and the shock upon opening is absorbed, as shown in FIG. In addition, it is only necessary to provide a small shock absorber 65 at the corners on both sides of the lower portion of the door opening 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. Thus, the structure of the fire hydrant door 18 is simplified, and a reduction in thickness and weight can be achieved.
