Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire hydrant device installed in a tunnel or the like and used for extinguishing a vehicle fire.
In particular, the present invention relates to a fire hydrant device that opens a door in the event of a fire and draws out a hose wound on a reel while discharging water from a nozzle to extinguish a fire.

[0002]

2. Description of the Related Art Conventionally, as a fire hydrant device installed in a tunnel such as a highway or a motorway, for example, a fire hydrant device as shown in FIG. 6 is known (Japanese Utility Model Publication No. 3-37646).
issue). In the fire hydrant device of FIG. 6, a door 101 of a cabinet case 100 installed on a tunnel wall or the like,
Hose 103 with nozzle 102 is replaced with hose reel 104
It is stored in a state wound around. In the event of a fire, by opening the door 101 as shown, the hose reel 104 installed inside the door is exposed in front of the cabinet 100, and the hose with nozzle 103 can be pulled out.

In this type of fire hydrant device, it is assumed that one person operates the fire hydrant. For this reason, the water discharge lever 105 installed in the door is operated to the open position in front of the fire hydrant and the nozzle 10 is operated.
The water for pressurized fire extinguishing is discharged from 2 and the hose 103 is drawn out from the hose reel 104 to extinguish the fire while discharging water from the nozzle 102.

[0004]

By the way, in such a conventional fire hydrant device, when the door is opened, the hose is easily pulled out in both the forward and left and right directions. The hose reel is installed inside the door so that it is exposed when opened. For this reason, it is necessary to make the door a robust structure so that the hose reel can be mounted, and the door has a built-in pipe to supply pressurized fire-extinguishing water to the hose wound around the hose reel. It has.

For this reason, the structure of the door becomes complicated and the weight becomes heavy, and a shock absorber such as a shock absorber is required in order to prevent an impact when the door is opened, so that a more complicated and heavy structure is unavoidable. Also, inside the cabinet case, a pressure regulating valve and a water discharge valve for supplying pressurized fire-extinguishing water to the hose with nozzle of the hose reel are installed. When the door is opened, a hose reel is attached to the door, so that the inside of the cabinet is difficult to perform. In particular, there is a problem in manufacturing that the adjustment work after the completion of assembly is extremely difficult.

Further, when the door is opened, the hose reel is placed horizontally, and the load of the entire hose reel is applied to the rotating shaft as a thrust force, so that there is a problem that the resistance when pulling out the hose is large. Furthermore, when the drawn hose is wound on a reel, it must be wound in order so that the hose is arranged vertically on the outer periphery of the drum of the reel. However, there was also a problem that it took time to wind up the hose.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems. Therefore, the door can be lightened to eliminate the structural and cost burden, the hose can be pulled out lightly, and the hose winding operation can be performed. An object is to provide an easy fire hydrant device.

[0008]

In order to achieve this object, the present invention is configured as follows. First, the present invention is directed to a fire hydrant device that extinguishes a fire by opening a door of a housing and pulling out a hose with a nozzle when extinguishing a fire. In such a fire hydrant device according to the present invention, a hose reel vertically arranged in a housing and wound around a hose with a nozzle and housed therein, and a hose reel arranged vertically in a housing horizontally from a door opening. And a swivel piping mechanism that can rotate around and be supported at a position exposed to the outside.

The swiveling pipe mechanism supports the hose reel side so as to swing freely in at least two stages around the horizontal with respect to the fixed side. The swivel pipe mechanism includes, for example, a fixed pipe that is set up and fixed in the housing, a first swivel pipe that is rotatably mounted on a tip of the fixed pipe via a rotary joint, and that is rotatable around a horizontal direction. It is composed of a second swivel pipe which is connected to a drum rotating part of a hose reel which is lowered from a mounted rotary joint and arranged vertically.

According to such a fire hydrant device of the present invention,
There is no need to attach a hose reel to the door of the apparatus, and the door structure is simplified, lightened, and opened and closed easily. In addition, the hose reel can be taken out from the door opening by the swiveling pipe mechanism while being hung horizontally around the door opening by a pipe. The hose can be turned to a horizontal position so as to be directed, and the hose can be smoothly pulled out in any direction, that is, in the forward direction and in the left-right direction.

Further, since the hose reel is taken out from the door opening and the hose reel is supported vertically, there is no problem that the rotation resistance is increased by the axial thrust force as in the conventional horizontal installation. The hose can be pulled out with a light and smooth rotation. At the same time, when the drawn hose is taken up, the hose reel is arranged vertically, so that the hose can be taken up lightly and smoothly on the reel.

Furthermore, since the reel of the wound hose with respect to the drum portion may be wound so as to be arranged in order in the lateral direction of the drum portion, the hose can be easily wound up and wound neatly. . Furthermore, since the swiveling piping mechanism supports the hall reel side so that it can swing freely in at least two stages around the horizontal with respect to the fixed side, the reel can freely change its direction according to the drawing direction or drawing direction of the hose. It is extremely easy to handle the hose when extinguishing the fire.

[0013]

FIG. 1 shows an embodiment of a fire hydrant device according to the present invention, in which a door is opened. FIG.
The fire hydrant device of the present invention has a cabinet case 1 buried and installed on a wall surface in a tunnel such as an expressway or a motorway, and a door 2 which can be opened and closed up and down on the front surface of the cabinet case 1 centering on a lower part. It has. Door 2
Is opened downward as shown, and the shock absorber 3
Supported in the open position. The inside of the door 2 forms a hose storage chamber 4.

A hose reel 5 is arranged vertically in the hose storage chamber 4. The rotation axis of the hose reel 5 arranged vertically is horizontal, and the hose reel 5 can rotate in the vertical direction. On the other hand, the conventional apparatus as shown in FIG. 6 can be said to have the hose reel 104 placed horizontally. The hose reel 5 vertically disposed in the hose storage chamber 4 can be turned horizontally around the door opening and exposed to the outside by a swiveling pipe mechanism using a pipe for supplying pressurized fire extinguishing water to the hose reel 5. It is supported by. This swiveling pipe mechanism is configured to stand at a tip of a fixed pipe 8 raised from a lower portion of the hose storage chamber 4 through a rotary joint 9 using a swivel joint or the like, and then to rise through a horizontal portion and then to a substantially U-shape. One end of the lower first swirl pipe 10 is connected.

A second swivel pipe 12 is rotatably connected to a falling portion of the first swivel pipe 10 on the hose reel 5 side via a rotary joint 11 also using a swivel joint or the like. The tip of the second swirling pipe 12 is bent in the horizontal direction, and connects the drum rotating shaft 5 a of the hose reel 5. An air release valve 13 for draining water is mounted on a horizontal portion of the first swirling pipe 10.

By having such a swivel pipe mechanism of the hose reel 5 including the fixed pipe 8, the rotary joint 9, the first swivel pipe 10, the rotary joint 11, and the second swivel pipe 12, the door 2 can be moved as shown in the figure. When the hose reel 5 is opened, the hose reel 5 is turned around the fixed pipe 8 at the horizontal radius of the first swirling pipe 10 as shown by the arrow A to expose the hose reel 5 to the outside of the cabinet case 1. Further, the second swivel pipe 12 side, that is, the hose reel 5 side can be swung as shown by the arrow B with respect to the first swivel pipe 10 via the rotary joint 11. That is, the hose reel 5
Can swing horizontally about the fixed pipe 8 in two stages.

The horizontal portion of the first swiveling pipe 10 connected to the upper part of the fixed pipe 8 via the rotary joint 9 is mounted on the inner side surface of the hose storage chamber 4 when swiveling outward as shown by the arrow A. The first swivel pipe 1 is fitted to the stopper 20.
The rotation position to the outside of 0 is maintained. On the other hand, a water supply pipe 14 from the fire extinguishing pump equipment is set up in a position not visible from the outside on the right side of the hose storage chamber 4 of the cabinet case 1, and the water supply pipe 14 is connected to the water discharge valve 15. It is connected to the primary side and the temporary side of the water tap 17 using a T-shaped joint. Subsequent to the water discharge valve 15, a pressure control valve 16 for adjusting the water discharge pressure from the nozzle 7 to a predetermined value is provided. The secondary side of the pressure control valve 16 is drawn out as a pipe 8a, and the lower part of the cabinet case 1 is indicated by a broken line. And connected to the rising portion of the fixed pipe 8. The pressure regulating valve 16 is provided with an automatic drainage valve 25 used for draining water from the piping.

The water discharge valve 15 can be opened and closed by a water discharge lever 18 provided inside the door 2. That is, the movement of the water discharge lever 18 is transmitted to the lever 15a of the water discharge valve 15 by the wire 19, and the water discharge valve 15 can be opened and closed by rotating the lever 15a. On the left side of the cabinet case 1, a fire extinguisher storage part 21 is formed, and a fire extinguisher door 22 is provided to be freely opened and closed. Further, another separate door is provided above the fire extinguisher door 22, and as shown by a broken line, a transmitter 23, a fire light 24, and an intercom jack are provided on this door.

Next, the unwinding operation of the hose in the embodiment of FIG. 1 will be described. FIG. 2 is a plan view of the embodiment of FIG. 1, in which the cabinet case 1 is installed in the guard path 27 on the side of the tunnel wall that is one step higher than the road surface. Guard fence 26
Is cut off. In the cabinet case 1, a rotary joint 9, a first swivel pipe 10,
The hose reel 5 supported by the rotary joint 11 and the second swivel pipe 12 is shown in a simplified manner.
Is mounted, and the nozzle 7 is held inside the door 2. When the door 2 is opened, the nozzle 7 comes to the front side as illustrated.

FIG. 3 shows a case where the nozzle 7 is taken out and the hose 6 is pulled out with the door 2 opened as shown in FIG. When the hose 6 is pulled out, the nozzle 7 held on the open door 2 is taken out as shown in FIG. 2, and then the water discharge lever 18 shown in FIG. While discharging the water, the hose 6 is pulled out in front of the fire vehicle as shown in FIG.

As the hose 6 is drawn forward,
The hose reel 5 is rotated counterclockwise by the first swivel pipe 10 around the rotary joint 9 on the fixed pipe 8 (not shown) side, and the hose reel 5 is unwound in a state where the unwinding direction is directed forward. 6 is withdrawn. At this time, the swirled first swirl pipe 10 hits the stopper 20 and is fitted and held.

For this reason, even if the forward direction and the drawing direction of the hose 6 move right and left, the hose reel 5 swings around the rotary joint 11 by the second swivel pipe 12 in response to the change in the drawing direction of the hose 6. The turning surface of the reel 5 is always oriented in the direction in which the hose 6 is pulled out, so that the hose 6 can be drawn out smoothly and lightly. FIG. 4 shows a case where the hose 6 is drawn leftward toward the cabinet case 1. Even when the hose 6 is pulled out to the left, the hose reel 5 protrudes outside from the illustrated door opening by the counterclockwise rotation of the first swivel pipe 10 around the fixed rotary joint 9. The first turning pipe 10 is held by the stopper 20 at this position.

Even if the first swivel pipe 10 is held by the stopper 20, the hose reel 5 turns the rotating surface in the hose pull-out direction in which the hose 6 is drawn out by the horizontal swivel of the second swivel pipe 12 with respect to the rotary joint 11. Pivots,
The hose 6 can be pulled out lightly and smoothly to the left. FIG. 5 shows a case where the hose 6 is drawn rightward toward the cabinet case 1. If the hose 6 is pulled out to the right as it is, the first swivel pipe 10 cannot be directly located at the open position where the stopper 20 holds the first swivel pipe 10. In this case, the hose reel 5 is first removed from the cabinet case 1. Pull out the first as shown
After holding the swirling pipe 10 on the stopper 20, the nozzle 7 is pulled out to the right from the hose reel 5.

For this reason, the hose reel 5 is
Of the first swiveling pipe 10 held at the tip of the rotary joint 11 around the rotary joint 11 so as to turn the reel rotating surface to the right in which the hose 6 is pulled out. Can be pulled out to the right. The hose reel 5 can be opened by the first swivel pipe 10 regardless of the direction of the hose drawer in any of the 45 ° directions centering on the forward direction toward the cabinet case 1 shown in FIGS. In the state where the hose reel is swung to the outside and exposed, the second swivel pipe 12 is swung around the rotary joint 9 so that the hose reel pull-out direction is the reel rotation surface, and the hose reel rotation surface is always pulled out. By directing the hose in any direction, the hose can be pulled out smoothly without causing the hose to become stiff even if the hose is pulled out in any direction.

Further, since the hose reel 5 rotates about a horizontally arranged rotation axis, a thrust force in the direction of the rotation axis does not occur unlike the conventional horizontal arrangement. For this reason, even if the hose length is increased and the reel weight is increased, the effect of the swinging action of always turning the reel rotating surface in the hose pulling direction and the reel vertical structure that does not generate the rotating force in the axial direction almost eliminates the effect. The hose can be pulled out smoothly from the reel with a light force without receiving it.

Next, the operation in the case where the hose 6 once pulled out is rewound on the hose reel 5 will be described. The fire vehicle was extinguished by pulling out the hose 6 while discharging water from the nozzle 7, and when the fire was extinguished, the hose lever 18 provided on the open door 2 in FIG. 1 was operated to the closed position to discharge water from the nozzle 7. To stop. When the water discharge is stopped, a staff member or the like performs a recovery operation of rewinding the hose 6 to the hose reel 5.

In the recovery operation for rewinding the hose 6 to the hose reel 5, the fire extinguishing water remaining in the hose 6 is first opened by opening the air release valve 13 provided in the horizontal portion of the first swirling pipe 10. Can be drained. At this time, since the hose reel 5 is located higher than the installation surface of the cabinet case 1, the fire extinguishing water remaining in the hose 6 can be easily drained from the nozzle 7.
Next, the water remaining in the pipe is drained by an automatic drain valve 25 provided in the automatic pressure regulating valve 16.

The hose 6 wound around the hose reel 5
Can be removed by completely unwinding the hose 6 from the hose reel 5. When the fire extinguishing water in the hose 6 is drained, the first swivel pipe 10 is swung outward and held by the stopper 20 as shown in FIGS. While feeding the hose 6, the hose 6 is wound up while being turned by a handle or the like provided on the side opposite to the rotation support side of the hose reel 5.

Even when the hose is wound, the hose reel 5 is rotatably supported by the horizontal rotating shaft with the support of the second swivel pipe 12, so that the wound hose 6 is transferred to the drum inside the hose reel 5. It is sufficient that the hose 6 is wound on the hose reel 5 in a simple and easy order, compared to the conventional case where the hose 6 is arranged so as to be vertically arranged as in the conventional horizontal installation. Can be wound up.

When the hose 6 is wound around the hose reel 5, the hose reel 5 is pulled in the direction in which the hose 6 is pulled out.
Since the rotation surface of the hose 6 is oriented, the hose 6 can be wound smoothly and lightly without causing the reel 6 to be wound around the reel. When the hose 6 is wound around the hose reel 5, if the head is swung by the second turning pipe 12,
Since the unnecessary swing of the hose reel 5 is caused by the tension caused by the winding rotation of the hose reel 5 by the handle or the like, a swing lock mechanism for locking the second turning pipe 12 at an arbitrary swing position is provided. It is desirable.

When the hose 6 pulled out to the hose reel 5 is completely wound in this way, the nozzle 7 at the tip of the hose 6 is mounted on the holder mounted on the inside of the door 2, and the first stopper 7 is inserted through the stopper 20. Push off the swivel pipe 10,
As shown in FIG. 1, the hose reel 5 is swung into the hose storage chamber 4 and then the door 2 is closed. At this time door 2
Merely holds the nozzle 7 at the tip of the hose 6, and otherwise only has a water discharge lever 18. The structure of the door 2 is simple and light in weight. In addition, the force for closing the door 2 can be reduced, and the door 2 can be easily closed to the cabinet case 1 to restore the original state.

Here, the first pivoting pipe mechanism for horizontally pivoting and exposing the hose reel 5 from the door opening to the outside is disclosed.
The horizontal length of the swivel pipe 10 is, for example, as shown in FIG. 3, the hose reel 5 centering on the rotary joint 11 in a state where the first swivel pipe 10 is rotated and held at a position held by the stopper 20. The length may be such that it does not hit the cabinet case 1 even when rotated within a range of 360 °.

Further, in the fire hydrant device of the present invention, the work inside the cabinet case 1 when assembling and adjusting the fire hydrant device can be extremely easily performed. That is, as shown in FIG. 1, valves and pipes such as a water discharge valve 15, a pressure regulating valve 16, a water tap 17 and the like are installed on the right side of the hose storage chamber 4 of the cabinet case 1. When the heat insulation work is performed, the hose reel 5 supported by the swivel piping mechanism in the hose storage chamber 4 becomes an obstacle.

In the present invention, the hose reel 5 is shown in FIG.
As shown in the figure, since the hose reel 5 can be horizontally turned outward and taken out of the hose storage chamber 4, the hose storage chamber 4 can be freely swung out of the door opening when the hose reel 5 is horizontally turned out. The worker can put his body in the cabinet case, and the work of assembling the valves and pipes in the cabinet case 1 and the adjustment work can be easily performed by putting the body through the door opening.

In the fire hydrant apparatus of the present invention, the door 2
Since the hose reel 5 is not mounted on the side, the door 2 can be assembled after the cabinet case 1 has been assembled. On the other hand, in the conventional fire hydrant device shown in FIG.
4, the cabinet case 100
If the door 101 equipped with the hose reel 104 was not assembled, the valves and pipes inside the cabinet case could not be assembled, and the door opening was obstructed by the hose reel, making the work extremely difficult. In the present invention, this has been completely solved.

Therefore, the fire hydrant device of the present invention has a high workability at the time of assembling adjustment, and the adjustment and repair during maintenance and inspection after installation can be performed very easily.

[0037]

As described above, according to the present invention, it is not necessary to mount a hose reel inside the door of the apparatus, so that the door structure can be simplified and lightened, the cost can be reduced, and the door can be opened and closed simultaneously. Can also be easily done. Also, the hose reel can be taken out from the door opening horizontally and suspended from the door opening by the swiveling pipe mechanism. The swiveling pipe mechanism has at least two-stage swing function horizontally, so that the hose reel is always in the hose pulling direction. The reel is rotated so that the rotation surface of the reel is turned, and the hose can be pulled out with a light force due to the smooth rotation of the reel in all directions around the horizontal 180 ° around the front of the apparatus.

Further, since the hose reel is taken out of the door opening and rotated in a vertically installed state, there is no problem that the rotation resistance due to the axial thrust force is increased as in the conventional horizontal installation. In any case, it can be rotated smoothly with a light force. Also, since the drum surface of the reel around which the hose is wound in the vertical position of the hose reel is horizontal, and the wound hose may be arranged in order in the horizontal direction with respect to the drum, the conventional horizontal reel As compared with the arrangement in the vertical direction in the above, the arrangement at the time of winding the hose is simple and can be neatly wound.

Further, when adjusting the assembly of valves and pipes on the housing surface from the door opening, the door opening is opened by turning the hose reel horizontally and out, and the body is inserted through the door opening. Thus, work on the housing surface can be easily performed, and assembly and adjustment of the device, and adjustment and repair at the time of inspection can be performed efficiently and easily.
