Description

TECHNICAL FIELD The present invention relates to a device for accommodating a fire hose used for fire fighting and the like.

[Prior Art] Conventionally, an apparatus of this type is configured as shown in FIG. 7 as an example.

In the figure, a is a substrate, b is a discharge part of pressurized water,
It communicates with a pump (not shown).

c is a valve, d is a flange, and e is a reel. The reel e has a shaft supporting portion f, a rotating shaft g, a hose winding portion h,
It is formed by the side plate i and the like, and a mechanical seal is provided in the bearing part j of the shaft support part f, whereby the rotating shaft g can be rotated in a liquid-tight state.
Reference numeral k denotes a connecting portion, which connects a water passage (not shown) in the rotating shaft g to the base end portion of the hose 1. The hose 1 is wound around the reel e as shown. m is hose l
Is a nozzle connected to the tip of the.

In the case of a fire or the like, the user can run to the fire site with the nozzle m, and another person can open the valve c. Then, water pressurized by a pump (not shown) is jetted from the nozzle m through the valve c, the inside of the rotation shaft g of the reel e, the connecting portion k, and the hose 1.

[Problems to be Solved by the Invention] However, the above conventional device has the following drawbacks. That is, a mechanical seal is provided on the rotation shaft g of the reel e so that the reel e is rotated in a liquid-tight state. Further, the water passage in the rotating shaft g and the hose 1 are formed to be connected by the connecting portion k. In short, since the water passage is provided inside and the rotating reel is formed, the device becomes complicated. Inevitably, it becomes expensive.

The present invention has been made to solve such a problem, and its object is to provide a fire hose which does not become a complicated and expensive device like the above-mentioned conventional device but has an extremely simple structure. It is to provide an accommodation device.

Another purpose is to provide a device that, when running to a fire scene with a nozzle m, and when it reaches there, does not require another person to open and close the valve as in the conventional case, but can automatically open the valve. It is to be.

Moreover, it is an object of the present invention to provide a device for accommodating a fire hose whose automatic opening is surely performed.

[Means for Solving the Problems] The present invention which achieves the above-mentioned object is described as follows. The upstream end of the base body 6 communicates with a water source of pressurized water, and the downstream end thereof has a discharge part. Water pipe 1 forming 11
2; a main valve 13 provided on the upstream side of the water pipe 12 that normally blocks passage of the pressurized water against the pressure of the pressurized water; and a water pipe downstream of the main valve 13 A water discharge valve 14 provided in 12 and having an opening / closing rod 18 that is not normally subjected to the pressure of the pressurized water; a cylindrical body 4 rotatably supported by a shaft core 7 provided in the base body 6; A reversing part 3 is formed from the middle of the direction to the opposite direction, and the hose 1 wound around the cylindrical body 4 with the reversing part 3 as a starting end; the nozzle 10 is connected to one end and the other end is discharged as described above A fire hose accommodating device comprising: the hose l; which is connected to the portion 11 and is bent near the other end in the direction of the opening / closing rod 18 and directly locked to the opening / closing rod 18. is there.

[Operation] When a fire occurs, first open the main valve 13, hold the nozzle 10 and run to the fire site. Then, the hose 1 connected to the nozzle 10 is unwound while rotating the tubular body 4.

Therefore, the hose 1 itself does not become twisted or entangled. When the fire spot is reached, the hose 1 is pulled toward the fire spot. As a result, the opening / closing rod 18
Is released by a hose 1 and the pressurized water is a nozzle
Water is discharged from 10.

Since the present invention is configured as described above, the shaft provided on the base body 6 does not require a complicated device such as a reel having the mechanical seal as shown in the above-mentioned conventional example to pass water inside. Since it suffices to have the cylindrical body 4 which is rotatably fitted to the core 7, the device can be made extremely simple. Therefore, the device can be made extremely inexpensive.

Further, the present invention is configured as described above, and is not the main valve 13 which blocks the passage of the pressurized water against the pressure of the normally pressurized water on the upstream side of the water passage 12, but rather the main valve 13 downstream of the main valve 13. ,
The opening and closing rod of the water discharge valve 14 that is not normally under the pressure of pressurized water
By directly locking the hose 1 to 18, it is possible to eliminate the risk that the valve 14 will be opened uncertainly by pulling the hose 1 when the device is used after many years.

In addition to the above effects, this is because the hose 1 is wound around the cylindrical body 4 by forming the reversing portion 3 and thus the problem of twisting due to unwinding is solved. Therefore, the hose 1 is directly connected to the opening / closing rod 18. The opening and closing rod 18 can be operated by stopping the operation, and the structure can be simplified without using a complicated device such as a lever. Also, there is no fear of entanglement of the hose.

[Embodiment] In FIG. 2, 1 is a hose, 2 is a connecting portion thereof, and the hose 1 is folded in half as a reversing portion 3 from a central portion in the middle of its length. It does not matter if this is not strictly in the central part.

Next, as shown in FIG. 3, the hose 1 is wound around the tubular body 4 from the inverting portion 3 and then wound as shown in FIG. Reference numeral 5 is a wound body formed in this way.

Next, the wound body 5 is rotatably fitted to the shaft core 7 provided on the base body 6 as shown in FIGS. 1, 5, and 6.
8 indicates a pedestal. Further, 9 is a support plate. One of the connecting portions 2 is connected to the nozzle 10 as shown in FIG.
The other connecting part 2 is connected to the discharge part 11 of the pressurized water.

The discharge part 11 is connected to a pump or the like (not shown) by a water pipe 12. Reference numeral 13 is a main valve, 14 is a water discharge valve, 15 is an extinguishant tank, 16 is a communication pipe between the tank 15 and the water passage 12, and 17 is a tank valve. The water discharge valve 14 is provided with an opening / closing rod 18, and the end of the hose 1 is directly hooked on the opening / closing rod 18, and when the fire is extinguished, the hose 1 is pulled in the direction of arrow A1 in FIG. At this time, the opening / closing rod 18 is rotated in the same direction. Then, a spring 20 is provided between the end of the rod 18 and the bracket 19 (FIG. 5) provided on the base 1, so that the opening / closing rod 18 rotates in the same direction about the shaft support 18a. When it is rotated by a slight angle, the spring 20 pulls the opening / closing rod 18 until it becomes horizontal, and thus the water discharge valve 14 is opened. Although not shown in the drawings, the side wall of the water pipe 12 and the opening / closing rod 18 are formed with a locking portion and an engaging portion, respectively.
Stops at the horizontal and vertical positions and does not rotate any further.

Note that the direct meaning of directly locking the hose 1 to the opening / closing rod 18 is not the case of locking the hose 1 through a complicated device such as an armature, and a simple locking tool or the like is provided. Since there is no problem even if it is stopped, such cases may be included.

Next, a connecting hole 21 is formed in the supporting plate 9 as shown in FIG. 6, and a connecting bolt 22 is inserted into this and a nut is inserted.
It can be fixed to each other by screwing 23 together.

By using the support plate 9, the winding body 5 can be attached in a plurality of stages as shown in FIG. 5 and FIG. In this case, by connecting the connecting portion 2 at one end of each wound hose 1 of the plurality of wound bodies 5 and connecting the other end of each to the nozzle 10 and the discharge portion 11, both hoses 1 are ready for use. Can be connected and used. Instead of using as described above, it is also possible to connect the two connecting portions 2 of either one of the winding bodies to the nozzle 10 and the discharging portion 11, respectively, and use the other winding body 5 as a spare. . In addition, 24 (FIG. 6) shows a fixed part. To describe the method of using the device shown in FIG. 1, first open the tank valve 17, open the main valve 13 in the event of a fire, hold the nozzle 10 and run to the fire site. Unwind while rotating. When you reach the fire site, pull the hose and open the opening / closing rod 18 of the water discharge valve 14,
The water pressurized by a pump (not shown) is discharged to extinguish the fire.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, there is no need for a complicated device such as a reel having the mechanical seal as shown in the above-mentioned conventional example to allow water to pass through the inside of the base body. Since the cylindrical body 4 rotatably fitted to the shaft core 7 provided in 6 is sufficient, a very simple device can be obtained. Therefore, the device can be made extremely inexpensive.

Further, the present invention is configured as described above, and is not the main valve 13 which blocks the passage of the pressurized water against the pressure of the normally pressurized water on the upstream side of the water passage 12, but rather the main valve 13 downstream of the main valve 13. ,
The opening and closing rod of the water discharge valve 14 that is not normally under the pressure of pressurized water
By directly locking the hose 1 to 18, it is possible to eliminate the risk that the valve 14 will be opened uncertainly by pulling the hose 1 when the device is used after many years.

In addition to the above effects, this is because the hose 1 is wound around the cylindrical body 4 by forming the reversing portion 3 and thus the problem of twisting due to unwinding is solved. Therefore, the hose 1 is directly connected to the opening / closing rod 18. The opening and closing rod 18 can be operated by stopping the operation, and the structure can be simplified without using a complicated device such as a lever. Also, there is no fear of entanglement of the hose.
