  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 portion, for example, storing 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.

  FIG. 2 is a front view showing the internal structure of the embodiment of FIG. 1 with the fire hydrant door and the maintenance door removed. In FIG. 2, a hose storage portion 36 is formed at the center of the housing 12, and a valve storage portion 38 is formed on the right side thereof.

  The hose storage portion 36 is provided with a hose bucket structure in which two bucket frames 40 are arranged in two upper and lower stages, and the bucket frame 40 is fixed to the rear surface of the housing and has a frame shape projecting forward in a U-shape. A hose storage space is formed inside.

  The two-stage bucket frame 40 surrounds the hose storage space in the housing horizontally around the door opening 16, and two hose guides 42 are arranged in the vertical direction in the front opening. A hose outlet is formed as a partition.

  FIG. 3 is an explanatory diagram showing the housing 12 taken out from FIG. In FIG. 3, the housing 12 has a box shape in which a partition plate is fixed to the left, right, top, and back of a frame member that constitutes a rectangular frame, and the front is opened to the front. A hose storage portion 36 and a fire extinguisher storage portion 39 are formed.

  The hose storage portion 36 has a hose bucket structure in which a pair of bucket frames 40 formed by bending a metal plate material into a U shape are arranged in two upper and lower stages by being fixed to the rear partition wall by a fixing member 45. A hose storage space is formed inside the casing surrounded by.

  Further, the left side (fire extinguisher storage 39 side) side surface of the bucket frame 40 is attached to a housing internal frame 42 that separates the fire extinguisher storage 39 and the hose storage 36 of the housing, and firmly fixes the bucket frame 40. In addition, the fire extinguisher storage part 39 and the hose storage part 36 are clearly separated. Since the fire extinguisher storage portion 39 and the hose storage portion 36 are open except for the bucket frame 40, it is easy to check the mutual state and transmit infection. A pair of hose guides 42 are disposed vertically on the front surface of the bucket frame 40, and a hose outlet is formed as a partition between them.

The hose bucket structure of this embodiment is basically a simple structure in which the two bucket frames 40 are horizontally arranged in two upper and lower stages, compared to the conventional structure shown in FIG. Assembling is easy and light, and space efficiency is high, so that a sufficient hose storage space can be secured in the housing.

  The bucket frame 40 and the hose guide 42 are curved so that the hose surface is not damaged when the hose is pulled out.

  Referring to FIG. 2 again, a hose 44 is housed in a hose housing portion 36 surrounded by a bucket frame 42 and a housing inner wall (upper surface, lower surface and back surface). Here, a hose connection port 46 is disposed in the right valve storage unit 38, and after connecting the primary side of the hose 44 to the hose connection port 46, the hose 44 is wound into the hose storage unit 36. However, in this case, the hose 44 is wound so that the hose 44 is clockwise when viewed from the door opening 16.

  That is, the hose 44 connected to the hose connection port 46 is first wound into the lower side of the hose storage portion 36, and then wound clockwise in the storage portion, and finally the hose tip attached with the nozzle 48 is connected to the bucket frame 40. A nozzle 48 is detachably attached to a nozzle holder 50 attached to a nozzle plate 47 fixed to the right side of the bucket frame 40, taken out from the hose outlet between the hose guides 42 provided at the front. The nozzle 48 is disposed in the vicinity of the fire hydrant valve opening / closing lever 60 to facilitate the water discharge operation.

  By storing the hose 44 in the right-handed inner winding with respect to the hose storage portion 36, the winding start portion 44 a of the hose 44 is sent to the lower portion of the hose storage portion 36 from the hose connection port 46 at the shortest distance.

  For this reason, as shown in FIG. 9, there is no hose portion (approximately half a turn around) that comes off from the hose storage portion when the hose 112 is turned counterclockwise and the hose winding start portion 112a is sent to the upper portion of the hose storage portion. Can be shortened, and the volume of the hose storage portion 36 is reduced. As a result, the casing 12 can be thinned.

  Further, the hose entrainment start portion 44a is fed to the lower side of the hose storage portion 36 by right-hand winding, so that the hose 44 does not slide against the bucket frame 40, and the conventional hose left-hand winding of FIG. There is no need for protection against sliding against the bucket, and the structure can be simplified.

  Further, the nozzle 48 at the tip of the hose taken out after being stored in the hose storage part 36 as a right-hand winding is detachably attached to the nozzle holder 50 with the water discharge part facing downward, and since the water discharge part faces downward, the fire hydrant door is attached. The nozzle 48 can be opened and removed with the water discharge part facing down, and the water will not be discharged unless the fire hydrant valve opening / closing lever 60 provided on the fire hydrant valve 54 is operated, but this is inexperienced for those operating in the event of a fire. Therefore, the nozzle 48 can be removed with a sense of security because the water outlet is not suitable for the user, and there is a great safety advantage.

  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 part 38 disposed on the right side of the hose storage part 36 provided in the housing 12 has a fire hydrant valve 54 connected to a piping system from the fire hydrant connection port 52 to which the piping from the pump facility is connected to the hose connection port 46. An automatic pressure regulating valve 56 and an automatic drain valve 58 are provided.

  That is, the pipe from the fire hydrant connection port 52 is connected to the primary side of the fire hydrant valve 54, the secondary side of the fire hydrant valve 54 is connected to the primary side of the automatic drain valve 58, and the primary side of the automatic pressure regulating valve 56. Connected to. The secondary side of the automatic pressure regulating valve 56 is a hose connection port 46 to which the hose 44 is connected.

  The hydrant valve opening / closing lever 60 is directly attached to the hydrant valve 54. That is, when the hydrant valve opening / closing lever 60 is in the closed position in the horizontal position shown in the figure, the hydrant valve 54 is in a closed state. At this time, there is no water for fire extinguishing in the piping, and there is no pressure, so the automatic drain valve 58 is open. It is in.

  When the fire hydrant valve opening / closing lever 60 is rotated clockwise and operated to the open position where the hydrant valve opens downward, the fire hydrant valve 56 is operated to the open position, the pressure rises in the pipe, and the automatic drain valve 58 is operated to the closed position. The As a result, the fire-extinguishing water pressurized from the water supply connection port 52 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 60 is turned on, whereby a signal is sent to the pump equipment and the pump equipment is started. When stopping the water discharge, when the hydrant valve opening / closing lever 60 is returned to the original horizontal position, the hydrant valve 54 is closed, and at the same time, the switch is turned off to stop the operation of the pump equipment.

  As described above, in the present embodiment, the fire hydrant valve opening / closing lever 60 that is conventionally provided on the fire hydrant door and opens and closes the fire hydrant valve by wire connection is arranged on the housing 12 side and directly provided 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.
