Description

The present invention relates to a fire hydrant device installed in a tunnel or the like.
In this specification, “back side” as a term for describing the positional relationship with respect to the fire hydrant device is the wall surface side of the tunnel in a state where the fire hydrant device is installed in the observer passage, and “front side” is the roadway Say the side.

  For example, as disclosed in Patent Document 1, a fire hydrant device installed in a tunnel or the like has a casing of the fire hydrant device installed in a “box opening portion formed on a tunnel wall surface”.

However, recent large-diameter tunnels are often constructed by a shield method, and in this case, the tunnel wall surface is constructed with steel segments simultaneously with the excavation of the tunnel. I can't unbox.
Therefore, it is conceivable that the installation place of the main body of the fire hydrant device is embedded not in the tunnel wall surface but in the supervisor passage, and there is a tunnel fire hydrant device disclosed in Patent Document 2 as such an embodiment.

Patent Document 2 discloses that, in a fire hydrant device for a tunnel installed in a tunnel having a supervisor passage constructed at a predetermined height along a shoulder of a tunnel side wall, the road surface of the supervisor passage A fire hydrant device for a tunnel, characterized in that the main body is housed in a space below the supervisor passage with the side wall on the side as the front of the device "(refer to claim 1 of Patent Document 2).
And in the fire hydrant device for tunnels indicated in patent documents 2, the hose reel which wound the hose is stored in the main part. The hose reel has a rotating shaft oriented in the vertical direction, and the hose is wound in the lateral direction.

  However, in the reel type, a rotational load is applied to the hose reel in order to prevent the hose reel from rotating vigorously when the hose is pulled out. For this reason, when pulling out the hose, it is necessary to pull it with a strong force that overcomes the rotational load. Because of this poor operability, the fire hydrant system often uses the reel type, including the type in which the hose is wound in the vertical direction. The current situation is not.

On the other hand, as a hose winding method that does not use a hose reel, for example, a so-called inner winding method described in the section [Technical field to which the invention belongs] of Patent Document 3 is known.
With respect to the inner winding type, Patent Document 3 states, “After forming the outermost winding row by pressing the proximal end side of the hose against the inner surface of the hose storage box, press the hose inside the hose of the winding row. The hose is housed in a hose storage box by repeating such a process to form the next row of windings ”(see paragraph [0002] of Patent Document 3).

JP2015-44039A JP 2001-9053 A JP 2002-291929 A

The fire hydrant device disclosed in Patent Document 3 is a type in which the casing has a short depth and a high height, and the hose is a so-called vertical winding type in which the opening of the wound cylindrical body faces from the front to the back. It is.
However, as disclosed in Patent Document 2, a casing having a long depth and a low height is preferable for installation in a supervisor passage in a tunnel. In this case, as disclosed in Patent Document 2 However, the hose must be wound so that the axis of the hose winds up and down.

However, when the inner winding method disclosed in Patent Document 3 (hereinafter referred to as the conventional method) is applied to the horizontal winding method as it is, there are the following problems. 9 and 10 are explanatory diagrams for explaining this problem. 9 and 10 are cross-sections of the hose, and the numbers in the circles indicate the winding order. (The same applies to FIGS. 4 to 8 described later).
FIG. 9 shows a state in which winding is completed, and FIG. 10 shows a state in the middle of winding.

  As shown in FIG. 9, according to the conventional inner winding type, the outermost row is wound in order from the bottom, and when it reaches the top, it enters the inner row from there and winds it down in order. In this case, there is no particular problem when winding the outermost row, but as shown in FIG. 10, the hose is in the air when winding the inner row (seventh circle in the figure) from top to bottom. Since there is nothing to support when it floats, it will be wound while supporting the hose by hand, and it is very difficult to wind

The walls forming the working space 87 are L-shaped. The road surface of the monitoring person passage 83 has an opening corresponding to the upper surface of the installation space 87, and an opening edge 91 of the opening is a peripheral portion of the top plate portion 9 of the fire hydrant device 1 described later (the overhang portion 13). The three sides on which the is placed are stepped lower by one step.

A fire hydrant apparatus 1 according to the present embodiment suitable for installation in the installation space 87 as described above will be described with reference to FIGS.
As shown in FIG. 1, the fire hydrant device 1 has a box-shaped main body portion 7 having a hose storage portion 5 that stores a hose 3 in a rolled state on its side and an upper surface opened, and an upper surface opening of the main body portion 7. The top plate part 9 to cover is provided.
Hereinafter, each part which comprises the fire hydrant apparatus 1 is demonstrated in detail.

<Main body>
The main body portion 7 in the present embodiment has a hose storage portion 5 and a fire extinguisher storage portion 11, and has a substantially rectangular parallelepiped shape with an open upper surface as shown in FIGS.
The shape of the main body portion 7 is a flat rectangular parallelepiped shape having a depth larger than the height.
Overhang portions 13 projecting outward are provided on both side portions and rear side portions (back side portions) of the main body portion 7.
The overhanging portion 13 is placed on a step portion formed in the opening edge portion 91 of the installation space 87 when the main body portion 7 is accommodated in the installation space 87. As a result, the overhang portion 13 and the top plate portion 9 are flush with the road surface of the supervisor passage 83. In addition, the overhang | projection part 13 should just be provided in at least 2 sides of both sides, and the step part of the opening edge part 91 should just be only in 2 sides of both sides in that case.

A red indicator lamp 15, an emergency button 17 for notifying the monitoring person that there is an emergency, and an emergency lamp 19 that is turned on when the emergency button 17 is pressed are provided on the front surface of the main body 7.
Hereinafter, the hose storage unit 5 and the fire extinguisher storage unit 11 will be described in detail.

《Hose storage part》
The hose storage part 5 has a flat rectangular bottomed frame shape with a depth larger than the height, and an operation for operating a fire hydrant valve (not shown) on the right side of the hose storage part 5 in the drawing. A lever 21 is provided.
The hose accommodating portion 5 accommodates the hose 3 in a sideways state (a direction in which a cylindrical body formed by the hose 3 is in a vertical state).
In the hose storage portion 5, four rod-like bodies 23 as winding jigs that come into contact with the hose 3 in the middle of winding at four positions within a predetermined distance from the four corners of the rectangle are detachably installed. An attachment portion 25 is provided for possible attachment. In addition, since the attachment part 25 does not connect the rod-shaped body 23 at the normal time other than when the hose 3 is wound and becomes an opening part, the attachment part 25 also functions as a drain hole in the normal time. .

Further, the hose 3 is wound from the outside to the inside in the hose storage portion 5 and then goes upward to be wound from the inside to the outside. The hose 3 is a shape retaining hose that maintains a substantially circular cross section.
Such a method of winding the hose 3 will be described with reference to FIGS.
In a state where the hose 3 is not wound, as shown in FIG. 3A, no jig is attached to the attachment portion 25 provided at the bottom of the hose storage portion 5. Although the specific aspect of the attachment part 25 is not specifically limited, For example, the thing which fixed the nut in which the internal thread was formed to the bottom part may be used. In this case, a male screw that engages with the female screw may be formed at the lower end of the rod-like body 23.

  In winding the hose 3, first, as shown in FIG. 3B, the rod-like body 23 is erected on the attachment portion 25. In this state, the winding of the hose 3 is started. First, as shown in FIG. 4 (a), the outermost circumference (first circumference) of the hose 3 is wound so as to be pressed against the inner surface of the hose storage portion 5, Next, the second circumference is wound while pressing the outermost hose 3 on the inner side of the outermost hose 3, and the third circumference, which is the innermost winding row, is further wound on the inner side. And as shown in FIG.4 (b), the 4th round is wound around the upper part of the 3rd round, but at this time, if there is nothing to support the 4th round from the inside, it can not be wound, In the present embodiment, the rod-like body 23 serves as a support portion for winding, and winding is possible. In other words, in the first stage (first to third laps), the hose 3 is wound while applying a force in the outward direction so as to contact the inner side of the hose 3 or the inner side of the hose storage portion 5. In the (4th to 6th laps), winding is performed while applying a force in the inner direction, so the rod-like body 23 is necessary, and the second stage is wound so as to contact the outer circumference of the rod-like body 23 or the hose 3. Turned.

On the fifth lap, it is wound around the outer side of the fourth lap, and similarly, it is wound up to the sixth lap. The seventh lap is wound in the same manner as the first lap, and thereafter the same winding is repeated (see FIG. 4 (c)), and finally shown in FIGS. 4 (d) and 3 (c). It becomes a state.
When the winding is completed as shown in FIGS. 4D and 3C, the rod-like body 23 is removed as shown in FIG. 3D, and the winding is completed.
In addition, the fire-extinguishing nozzle 27 attached to the front-end | tip of the hose 3 is mounted or hold | maintained by this side in the accommodation state of the hose 3 which winding was completed.
In the first embodiment, the hose 3 is wound around each stage three times. However, how many turns the hose 3 is wound depends on the size of the hose storage portion 5, the standing position of the rod-like body 23, and the hose 3. It is set appropriately depending on the thickness of the.

<Fire extinguisher storage>
The fire extinguisher storage unit 11 can store a plurality of (two in this example) fire extinguishers 29 while lying sideways. In the present embodiment, as shown in FIG. 1, the two fire extinguishers 29 are laid down and stored in the width direction of the main body portion 7 below the second front side top plate portion 37.
In addition, the fire extinguisher storage unit 11 of the present example stores the fire extinguisher 29 so that the upper side of the fire extinguisher 29 is slightly higher.
When the fire extinguisher 29 is taken out, the lever 30 provided at the upper part of the fire extinguisher 29 is held, so that the upper side of the fire extinguisher 29 is raised so that the fire extinguisher 29 is laid sideways. However, the lever 30 can be easily held and the fire extinguisher 29 can be easily taken out.

  In addition, you may make the mounting surface in which the fire extinguisher 29 in the fire extinguisher accommodating part 11 is mounted into the inclined surface which becomes a further downward inclination toward this side. By providing such an inclined surface, when the fire extinguisher 29 on the near side is taken out, the fire extinguisher 29 on the far side slides and moves to the near side, so that the take out becomes easier.

<Top plate>
As shown in FIG. 2, the top plate portion 9 is largely divided into two on the back side and the near side, the back side is composed of the back side top plate portion 31, and the front side is the inspection top plate portion 33, The first front side top plate portion 35 and the second front side top plate portion 37 are configured.
In the closed state, the top plate portion 9 can be passed by an operator as the road surface of the supervisor passage 83.

The back side top plate part 31 is fixed with screws or the like so that it can be opened at the time of inspection without being opened at all times.
The division position of the top plate portion 9 is located above the hose storage portion 5. For this reason, as shown in FIG. 1, the back side top plate part 31 covers the hose 3 in a plan view even when the first front side top plate part 35 is opened. With this arrangement, the back side top plate portion 31 abuts on the hose 3 when the hose 3 is pulled out and functions as a hose pull-out restricting means. That is, if there is nothing that covers the upper part of the hose 3, there is nothing that restricts the movement of the hose 3 when the hose 3 is pulled out after operating the operation lever 21 to open the fire hydrant valve. 3 may be unraveled by water pressure or unraveled randomly, but the rear side top plate 31 is disposed so as to cover the hose 3, thereby preventing the hose 3 from being in contact with the hose 3. Or restricting attempts to unwind uncontrollably.
In the first embodiment, the division position of the top plate portion 9 is located in the center portion in the depth direction of the top plate portion 9 and is located in the center portion in the depth direction of the hose storage portion 5.

As for the 1st near side top plate part 35 and the 2nd near side top plate part 37, the back side part is attached to the back side top plate part 31 so that rotation is possible.
The first front side top plate part 35 and the second front side top plate part 37 are always urged in the door opening direction by the gas spring 39, and in the open state, as shown in FIG. 41 is held in an upright state.

  In the gas spring 39, the lower end side of the cylinder rod 43 is fixed to the bottom portion of the main body portion 7 so as to be rotatable, and the upper end side of the cylinder 45 is rotated to the first front side top plate portion 35 and the second front side top plate portion 37, respectively. Connected as possible. The gas spring 39 has a biasing force that turns the first front side top plate part 35 and the second front side top plate part 37 from the closed state to bring them into the open state. And the 1st near side top plate part 35 and the 2nd near side top plate part 37 hold the 1st near side top plate part 35 and the 2nd near side top plate part 37 in the closed state, or let the door open. An operation unit 47 is provided. The operation part 47 has a latch 49 (see FIG. 1). When the door is closed, the latch 49 is locked to the main body part 7 so as to keep the door closed.

In addition, since the closed state of the first front side top plate part 35 and the second front side top plate part 37 cannot be reliably maintained by the latch 49 alone, the latch mechanism 51 that is interlocked with the operation of the latch 49 is provided in the present embodiment. ing. The latch mechanism 51 is connected to the operation unit 47 via the wire 53. By opening the operation unit 47, the latch 49 of the operation unit 47 and the latch mechanism 51 can be opened simultaneously, and only the operation of the operation unit 47 is operated. Thus, the opening operation of the first front side top plate portion 35 and the second front side top plate portion 37 can be performed.
In the above description, the means for interlocking the latch 49 and the latch mechanism 51 when the operation unit 47 is operated has been described as the wire 53. However, any means may be used as long as the latch 49 and the latch mechanism 51 are interlocked. The same interlocking can be performed even if is used.

The upright holding means 41 has one end side rotatably attached to the first front side top plate part 35 and the second front side top plate part 37 and the other end side provided so as to be able to be locked to the main body part 7. It is comprised by the plate-shaped member (refer FIG. 3).
The other end of the upright holding means 41 is inserted into a narrow groove 55 provided in the main body 7, and when the first front side top plate 35 or the second front side top plate 37 is in an upright state. It can be locked to the peripheral edge of the narrow groove 55.
The first front side top plate part 35 and the second front side top plate part 37 are preferably upright in a standing state, but may be tilted forward or rearward if they are slightly from the closed state. It only needs to be held by rotating about 80 to 100 degrees.

  The inspection top plate 33 is normally fixed with a screw and closed, and can be opened by removing the screw only during inspection. A piping system (not shown) and the like are disposed below the inspection top 33.

The operation of the present embodiment configured as described above will be described.
When the latch 49 and the latch mechanism 51 are unlocked by operating the operation unit 47 of the first front side top plate part 35 from the state in which the first front side top plate part 35 is closed (see FIG. 2), The front top plate portion 35 is automatically opened by the urging force of the gas spring 39 and is held in an upright state by the upright holding means 41 as shown in FIG.
The second front side top plate portion 37 is also opened by the same operation as the first front side top plate portion 35. Therefore, the door opening operation of the first front side top plate portion 35 and the second front side top plate portion 37 can be performed extremely smoothly and easily.
The urging force of the gas spring 39 is preferably such that the first front side top plate part 35 and the second front side top plate part 37 are automatically opened, but the urging force is more than that. Even in such a case, it is an auxiliary force when the first front side top plate part 35 and the second front side top plate part 37 are manually opened.

In the fire hydrant device 1 of the present embodiment configured as described above, the top plate portion 9 is normally closed, and the top plate portion 9 can be used as the supervisor passage 83.
In the event of a fire, for example, in order to pull out the hose 3, the operation unit 47 is operated to open the first front side top plate part 35. This door opening operation is also monitored from the roadway 85 side. It can also be performed from above the staff passage 83. Therefore, as in the case disclosed in Patent Document 2, the fire extinguishing activity can be smoothly performed as compared with the case where the tray is pulled out only from the roadway 85 side.

When the first front side top plate part 35 and / or the second front side top plate part 37 are opened, the hose 3 is pulled out and the fire extinguisher 29 is taken out. Or from the supervisor passage 83 side.
Moreover, since the 1st front side top-plate part 35 and the 2nd front side top-plate part 37 hold | maintain a standing state as shown in FIG. 1 in the door open state, use the back side top-plate part 31 as a channel | path. Even in this respect, the worker can move smoothly, and fire extinguishing activities can be performed efficiently.

  When the first front side top plate portion 35 is opened and the fire is extinguished by the hose 3, the operation lever 21 is operated, and the hose 3 is pulled out by holding the fire extinguishing nozzle 27. At this time, since the hose reel is not used, it is possible to smoothly pull out the hose 3 without requiring excessive force. In addition, the presence of the back-side top plate portion 31 can prevent the hose 3 from being violated by water pressure or unraveling.

  In the above embodiment, the four rod-like bodies 23 are exemplified as the winding jig. However, the winding jig of the present invention is not limited to this, and a predetermined amount is formed inward from the four corners of the rectangle. The shape is not particularly limited as long as it has a function of coming into contact with a hose in the middle of winding at four locations that are separated from each other. For example, a rectangular box shape may be used. When the winding jig is box-shaped, it has a function of coming into contact with a hose that is being wound even if it is not fixed to the hose storage 5.

  In the above embodiment, the top plate portion 9 is divided into two in the depth direction. However, the top plate portion 9 of the present invention may not be divided in the depth direction. In this case, the side part on the back side of the top plate part 9 may be attached to the upper side part of the main body part 7 so as to be rotatable.

[Embodiment 2]
In the first embodiment, the hose 3 is wound from the outside to the inside and then goes to the upper side and then wound from the inside to the outside. However, the fire hydrant apparatus of the second embodiment is a method for winding the hose 3. Are different, and other configurations are the same as those of the first embodiment. In addition, although the winding method of the hose 3 is different, the point that the hose 3 is finally wound sideways (the cylinder formed by the hose 3 in the rolled state is stored vertically) is stored. Is the same as in the first embodiment.
Therefore, only the method of winding the hose 3 will be described below.

  As shown in FIG. 5, the hose 3 according to the second embodiment is wound on the inner surface of the hose storage portion 5 while being wound from the bottom to the top to form the outermost winding row. The hose 3 is repeatedly wound while being pressed between the hose 3 disposed above and below the outer winding row.

  In order to realize the winding method as described above, a step corresponding to the position of the winding line from the outside to the inside is formed at the bottom of the hose storage portion 5. Specifically, a ring-shaped convex portion 59 is formed at the position of the second row. The purpose of providing the step is to provide a difference in height of about half the hose diameter between the outer winding and the inner winding, so that the height of the convex portion 59 is from the half of the hose diameter to the hose. The range is set slightly lower than the half height of the diameter. Note that the step corresponding to the position of the winding line from the outside to the inside is not limited to the convex portion 59 but may be a concave portion.

A winding method according to the second embodiment will be described with reference to FIGS.
Wind the first circumference against the inner surface of the hose storage 5 while winding it, wind the second circumference on it, and further on the third, fourth, fifth, and uppermost part of the outermost circumference Is wound around the sixth turn (see FIG. 6A). Next, the seventh circumference is wound inside the outermost circumferential row. At this time, as shown in FIG. 6 (b), the hose 3 is arranged about half the hose diameter above the sixth circumference, By placing the hose 3 on the upper half of the sixth hose 3, the seventh hose 3 can be supported and wound by the sixth hose 3.

The 8th lap is positioned between the 5th and 6th lap hoses 3, so that it is pressed against the 5th and 6th lap hoses 3 and supported by the 5th lap hose 3. And roll it up. Similarly, it is wound up to the 12th circumferential surface. The twelfth circumferential surface is supported by the upper surface of the convex portion 59 as shown in FIG.
The thirteenth turn is the third row, and the winding is completed by winding upward from the bottom of the hose storage portion 5 and winding up to the eighteenth turn (FIG. 6 ( d)).

As described above, according to the second embodiment, the outer hose is wound when the outer row is wound from the bottom to the top and the inner row is wound from the top to the bottom as in the conventional inner winding type. This is made possible by supporting the hose 3 with 3.
5 and 6, the convex portion 59 is provided so as to correspond to an even number of winding rows, and it is applied even if the hose 3 is wound after the fourth round.

In addition, as a method of forming the level | step difference corresponding to the winding row | line from the outside to the inside in the bottom part of the hose accommodating part 5, it is not restricted to what is shown in FIG. 5, FIG. 6, for example, as shown in FIG. A ring-shaped first convex portion 61 set in a range corresponding to (first row) from a height of half the hose diameter to a height slightly higher than half the hose diameter corresponds to the third row. You may make it form the ring-shaped 2nd convex part 63 in a position.
In this case, as shown in FIG. 7 and FIG. 8B, the seventh circumference, which is the uppermost part of the second row, is arranged between the fifth circumference and the sixth circumference, The hose 3 on the circumference may be supported by the hose 3 on the fifth circumference.

The hose 3 in the twelfth circumference, which is the lowermost part of the second row, is wound around the bottom of the hose storage portion 5, that is, between the first convex portion 61 and the second convex portion 63. Then, the hose 3 on the thirteenth round is placed on the upper surface of the second convex portion 63 and wound, and further wound upward to complete the winding on the eighteenth round.
In the case of FIGS. 7 and 8, the convex portions 61 and 63 are provided so as to correspond to an odd number of winding rows, and this is applied even if the hose 3 is wound after the fifth round.
In the examples of FIGS. 7 and 8, the convex portions 61 and 63 are described as being provided at positions corresponding to the outermost circumference (first row) and the third row. You may combine a convex part and a recessed part.

The convex portions of the second embodiment only have to be provided alternately in odd rows or even rows, and in either case, the hose 3 is wound inside by using the hose 3 without using a winding jig. 5 can be stored.
Moreover, a convex part does not need to be a ring-shaped convex strip part, and the convex part should just be arranged in multiple numbers on the same periphery. Even in that case, since the hose 3 is a shape-retaining hose, it can be wound.
In the second embodiment, the rows around which the hose 3 is wound are described as three rows. However, the number of rows around which the hose 3 is wound depends on the size of the hose storage portion 5 and the rod-like body 23.
