Description

[Detailed Description of the Invention] The present invention mainly relates to a fire hydrant device installed indoors and outdoors.

Conventionally, general fire hydrant devices use a fire hose made of polyester thread, vinylon thread, etc. with rubber glued to the back side, and a nozzle is attached to the tip of the hose, and the base end is connected to the discharge part of the fire hydrant. connected directly to. In order to store the fire hose compactly in a fire hydrant storage box, the hose is bent and hung on a hose holder equipped with many comb rods, or the hose is folded in half at the center and then reeled. It is wrapped around the

Conventional general equipment is configured as described above, so
The fire hydrant valve could not be opened unless the fire hose was completely removed from the hose tether or reel and water was ready to be released. If you open the valve while the fire hose is hung on a hose rack or wound on a reel, the water channel inside the hose will become flat and blocked, making it impossible to release water, and the water pressure will cause damage to the equipment. There was a problem that it could lead to damage.

Therefore, according to conventional general equipment, at least two people are required to extinguish a fire, one operating the fire hose and the other opening the fire hydrant valve, and one person who discovers the fire can quickly extinguish the fire in the initial stage. The disadvantage was that it was difficult to carry out activities. In addition, with conventional conventional equipment, water cannot be sprayed unless the fire hose is completely removed from the hose mount or reel, resulting in a time lag before water is sprayed, and the fire hose, which is about 30 meters long, is often left unattended around the fire hydrant storage box. This had the disadvantage of interfering with fire extinguishing activities.

It is an object of the present invention to provide a fire hydrant device which corrects all of the drawbacks of the above-mentioned conventional examples, and which has a simple structure in which the reel can be stored compactly.

The present invention will be explained in detail below based on embodiments shown in the drawings. Inside the storage box 1, a reel 2, a reel support device 3, a fire hydrant 4, a fire hose 5, etc. are arranged at predetermined positions, and a door 6 is provided in the front. The reel support device 3 includes a support shaft 7 fixed to the inner peripheral side wall of the storage box 1, and a substantially U-shaped first frame body pivoted to the support shaft 7 so as to be able to swing in the horizontal direction. 8. It consists of a rectangular second frame 9 which is pivoted at the tip of the first frame 8 so as to be able to swing in the horizontal direction. Reel support parts 10a and 10b protruding toward the center of the reel 2 at a mid-height position between the left and right frames of the second frame 9 have shafts of a water conduit 11 consisting of a pair of mating pipe bodies 11a and 11b. Supported (Figure 3). The first pipe body 11a on the fire hydrant side is fixed to the reel support part 10a using a nut 12, and the second pipe body 11b on the fire hose side is rotatably supported by the reel support part 10b. The second pipe body 11b is bent in an L-shape, and its distal end 13 extends in the centrifugal direction of the reel 2, that is, toward the fire hose winding part 14 of the reel 2, and further changes direction at right angles at the distal end to reel 2. Opens in the tangential direction.
The second tubular body 11b is fixed to the reel 2 via a connecting member 15, and the second tubular body 11b and the reel 2 are configured to rotate together. Said first tube body 11
a is arranged so as to coincide with the central axis of reel 2,
The base 17 of the second tube 11b is fitted into this tip 16 in a watertight manner, and a bearing 18 is interposed between the first tube 11a and the second tube 11b, so that the reel 2 rotates around its central axis. Configure it to rotate freely.

The base of the first pipe body 11a, that is, the water pipe 1
The inflow section 19 of the fire hydrant 4 and the discharge section 20 of the fire hydrant 4 communicate with each other through a flexible water guide hose 21. As the water guide hose 21, a conventionally commonly used flexible hose may be used, but it is also possible to use a hose similar to the fire hose of the present invention.

The proximal end 2 of the fire hose 5 is disposed at the tip end of the second pipe body 11b, that is, at the discharge section 22 of the water conduit 11.
Connect 3. This fire hose 5 is different from conventional fire hoses and has shape retention properties. A fabric 25 made of polyester thread, vinylon thread, etc. is wound around the outer periphery of a spiral core wire 24 made of hard synthetic resin, and this fabric 2
The surface of the core wire 24 is coated with a wear-resistant synthetic resin 26, and the inner circumference of the core wire 24 is bonded with rubber 27. Therefore, this fire hose 5 is lightweight and easy to handle like the conventional one, and the spiral core wire 24 always maintains a substantially circular cross-sectional shape, so that even when wound on the reel 2, the waterway remains intact. Keep it open.

In the figure, 28, 28 are a pair of left and right disk bodies which are the main constituent members of the reel 2, and 29, 29... are long bolts that hold the left and right disk bodies 28, 28 in a predetermined shape.
A fire hose 5 is placed around these long bolts 29, 29...
Wrap it around. Further, 30 is a nozzle attached to the tip of the fire hose 5, and 31 is a handle for operating the valve of the fire hydrant 4.

In the above embodiment, the reel support member (second
This applies to the frame. ) 9 is pivotally supported by a support member consisting of a support shaft 7 and a first frame 8 so as to be able to swing in the horizontal direction. The device is configured to be able to swing in two stages: swinging around the support shaft 7 and swinging around the distal end portion of the first frame 8. The present invention is not limited to this, and includes a case where the swing is one step. Further, in the above embodiment, the central horizontal axis of the reel 2 is aligned with the first tube body 1.
1a, but the present invention is not limited thereto. Also, as shown in Figure 1, the center horizontal axis of reel 2 must be located approximately at the center of storage box 1 when reel 2 is stored, but "approximately at the center" means that reel 2 is located at a small depth. It must be interpreted from the viewpoint that it can be efficiently stored in the compact storage box 1.

As explained above, the fire hydrant device of the present invention has a central horizontal axis attached to a reel support member which is pivoted so as to be able to swing in the horizontal direction by a support member disposed on one side of the storage box. rotatably supports a reel located approximately in the center of the storage box when stored, and connects the inlet of the water conduit installed in the center of the reel with the outlet of the fire hydrant through a flexible water conduit hose. The base end of a fire hose is connected to the discharge part of the water guide pipe that opens toward the water guide hose wrapping part, and the fire hose is configured with a shape-retaining hose, so that: It has the following advantages.

Since the fire hose 5 having shape retention properties is used and the base end 23 of the fire hose 5 is connected to the discharge part 22 of the water conduit 11 disposed in the center of the reel 2, the fire hose 5 There is no need to fold the fire hose 5 into two, and even when wound on the reel 2, the water channel formed inside the fire hose 5 has a substantially circular cross section and is always open. Therefore, the person who discovers the fire opens the valve of the fire hydrant 4, and then unwinds the fire hose 5 from the reel 2 and connects it to the nozzle 3.
0 can be carried to a desired location and sprayed with water, allowing rapid initial firefighting to be carried out independently. Of course, water starts discharging immediately after opening the valve, resulting in water discharging to areas where it is not needed, but these disadvantages are minor compared to the above-mentioned advantages.

Although the fire hose 5 is wound around the reel 2, the waterway is always open regardless of the length of the winding. Therefore, during firefighting, the necessary length of fire hose 5 is attached to the reel 2.
It only needs to be fed out more, and water can be sprayed onto the desired location extremely quickly. Further, since no redundant fire hose 5 is left around the storage box 1, fire extinguishing activities can be carried out smoothly.

Support members 7 and 8 arranged on one side of the storage box 1
The reel 2, whose central horizontal axis is located approximately at the center of the storage box 1 when stored, is rotatably supported by the reel support member 9, which is pivotably supported by the reel support member 9 so as to be able to swing in the horizontal direction. The reel 2 can be stored by effectively utilizing the internal space of the storage box 1, and even when the reel 2 is horizontally rotated forward and put into use, the support members 7 and 8 are attached to one side of the storage box 1. Since it is arranged on the side, even if the storage box 1 has a small depth, interference between the storage box 1 and the reel 2 is prevented, and as a result, it is possible to provide a fire hydrant device in which the reel 2 can be stored compactly.

Despite having the advantages mentioned above, the structure can be made simple. That is, the water conduit 1 disposed in the center of the reel 2
Since the inflow section 19 of the fire hydrant 1 and the discharge section 20 of the fire hydrant 4 are communicated with each other through a flexible water guide hose 21, the reel 2 can be freely swung, but it has a simple structure that does not require seals or the like. can be taken as a thing.
