The fire extinguisher door 8 is opened by pulling a handle 14 formed on the upper right side of the fire extinguisher door 8 toward the front.

  In this embodiment, since the fire hydrant door is a forward-extinguishing type fire hydrant door 7, it is necessary to arrange necessary members (such as a nozzle for water discharge), and thus the forward tilting type of the prior art that has to have more strength is required. It can be made thinner than a fire hydrant device equipped with a fire hydrant door.

  The box 6 is provided with a hose accommodating portion 15 for accommodating a hose 3 having a predetermined length, and the hose accommodating portion 15 has a substantially rectangular shape so that the hose 3 is formed with a horizontal portion 3c on the upper portion thereof. It is housed by being wound in an anti-clockwise direction (hereinafter also referred to as “left-handed”).

  The hose accommodating part 15 is provided with a hose guide 16 that supports the horizontal part 3 c when the hose 3 is accommodated in the hose accommodating part 15. A plurality of hose guides 16 are provided in accordance with the number of stages where the hose 3 is wound. In addition, the hose accommodating part 15 is comprised by the box shape in which the opening for pulling out the hose 3 to the exterior of the housing | casing 2 was formed in the front surface, The top | upper surface 15a, the bottom face 15b, and the back surface (inner surface 6a) are It also serves as the inner wall of the housing.

The hose guide 16 is a substantially plate-like member extending in the horizontal direction, and is attached to the inner surface (back surface) 6a of the box body 6 so as to be inclined upward. The inclination angle θ ₁ can be selected as appropriate. However, it is preferable that 0 <θ ₁ ≦ 30 ° so as not to cause resistance when the hose 3 is pulled out from the hose accommodating portion 15 during the fire extinguishing operation. In the present embodiment, θ ₁ = about 10 °.

  By providing the hose guide 16, the hose 3 can be wound in an orderly manner even if the width of the hose accommodating portion 15 is increased, and when fire-extinguishing water is supplied to the hose 3 for water discharge, the hose 3 is wound by its weight. Since the horizontal portion 3c of 3 does not hang down, it is possible to prevent the fire fighting operation from being hindered.

  Even if the hose guide 16 is attached so as to incline forward, even if the hose 3 is violated due to the force that the hose 3 tends to extend in the outer peripheral direction of the hose accommodating portion 15 due to the supply of fire-extinguishing water. Further, the unintended hose 3 can be prevented from jumping out of the hose accommodating portion 15, and the fire fighting operation can be prevented from being hindered.

Further, the hose guide 16 has notches 17 on its side portions 16b and 16c so that it does not become a resistance when pulling out the hose 3 from the hose accommodating portion 15 during fire extinguishing work, especially when pulling in the direction opposite to the winding direction of the hose 3. It is formed and has a substantially trapezoidal shape with a tapered front side. The inclination angle θ ₂ of the notch 17 can be selected as appropriate, but in the present embodiment, θ ₂ = about 45 °.

Further, the length of each hose guide 16 is formed so as to gradually shorter toward the most bottom 15b side of the hose guide 16 _Q from the most top 15a side of the hose guide 16 _F, the winding direction side of the hose guide 16 (As in this embodiment, the hose 3 is attached to the hose accommodating portion 15 with its vertical position aligned in the left direction when the hose 3 is wound in the left direction and the right side in the right direction). That is, the direction opposite to the winding direction of each hose guide 16 (on the right side when the hose 3 is wound counterclockwise and on the left side when the hose winding direction is right) is arranged to be stepped. Become.

  The hose 3 has a base end portion 3 b connected to a fire hydrant valve (not shown) via a maintenance valve 19 and a tip end portion 3 a connected to a water discharge nozzle 4 via a plug joint 20. Moreover, this hose 3 is normally accommodated in the hose accommodating part 15 of the box body 6, and is pulled out from the box body 6 at the time of fire extinguishing work.

In the illustrated example, the hose 3 is accommodated in a substantially rectangular shape in three rows and four tiers so that the horizontal portion 3c is formed in the hose accommodating portion 15, and the first hose _3F is The hose guide 16 _F on the most top surface 15a side, the second hose 3 _S is directly below the hose guide 16 _S , the third hose 3 _T is on the hose guide 16 _T , and the fourth hose. Guide 3 _Q is accommodated in the inner winding from the back in each column as its horizontal part 3c most of the bottom 15b side hose guide 16 _Q is supported. In addition, the number of rows, the number of steps, and the like of the hose 3 in the hose accommodating portion 15 can be appropriately determined according to the length of the hose 3 and the like.

At this time, it is preferable that the direction opposite to the winding direction of each hose guide 16 is arranged in a stepped manner as in this embodiment. The hose 3 is bulky for passing the hose 3 between each row and each step on the side opposite to the winding direction of each hose guide 16, but the side opposite to the winding direction of each hose guide 16 is arranged stepwise. As a result, the delivery position of the hose 3 can be shifted between the respective stages, so that the hose 3 can be prevented from becoming difficult to wind due to the bulkiness of the hose 3. In particular, for example, the third column in the first stage the hose 3 _F of (front side) after receiving the hose guide 16 _F, 1 column in the second stage the hose 3 _S of (rear side) to the hose guide 16 _S It becomes easy to accommodate.

  Further, by providing the hose guide 16, it is possible to easily accommodate the hose 3 which required a skillful technique.

  In the fire extinguishing operation, when the fire water is supplied into the hose 3, the horizontal portion 3c of the hose 3 is supported by the hose guide 16, so the horizontal portion 3c is caused by the fire water, the dead weight of the hose 3, etc. It is possible to prevent sagging.

  The fire hydrant device 1 can accommodate the hose 3 with a substantially rectangular inner winding so as to form the horizontal portion 3c in the hose accommodating portion 15 by the hose guide 16 extending in the horizontal direction. Can be longer in the direction. Therefore, the number of rows can be reduced without shortening the hose 3, and the volume of the housing 2 (box body 6) can be used effectively while preventing the fire fighting activity from being hindered. The fire hydrant device 1 can be thinned.

  The fire hydrant device 1 is installed in a state of being embedded in a side surface of a tunnel or the like (not shown) such as an expressway or an automobile exclusive road. In the conventional fire hydrant device, a depth of about 200 mm is required to accommodate the hose 3 having a predetermined length. Therefore, the depth of the fire hydrant device cannot be less than 200 mm, and the depth is about 300 mm. On the other hand, since the fire hydrant device 1 can effectively use the volume of the housing 2 (box 6), the depth of the fire hydrant device 1 as a whole is about 200 mm without requiring a depth of about 200 mm to accommodate the hose 3. The following can be suppressed.

  And if the depth of the fire hydrant device 1 can be suppressed to 200 mm or less, it becomes possible to install without reinforcing the installation space provided on the side surface of the tunnel or the like. The fire hydrant apparatus 1 includes a fire hydrant valve (not shown) and an automatic pressure regulating valve (not shown) arranged on the secondary side thereof as a fire hydrant valve unit outside the housing 2 to provide a water supply source ( It is installed at a branch from a water distribution main (not shown) connected to a not-shown.
