Description

  The present invention relates to a fire hydrant device, and more particularly, to a fire hydrant device in which a fire hose is housed in an internal winding.

  For example, a fire hydrant device installed in a tunnel or the like is equipped with a fire hose having a nozzle at the tip, but in general, a fire hose is usually housed in a state of being wound around the inside of the device and in the event of a fire It is pulled out of the device and used for fire extinguishing.

  In this type of fire hydrant device, there is a so-called inner wrap type fire hydrant device in which a fire hose is wound around an inner wrap and stored.

  The internally wound fire hydrant device has a hose housing portion inside the device, and can be housed in the hose housing portion by sequentially winding a fire hose from the outside toward the center side. An opening is provided at the front so that the fire hose can be pulled out of the hose storage and the fire hose can be stored in the hose storage.

  Generally, in an internally wound fire hydrant device, when a fire hose is pulled out with fire water supplied, the fire hose comes out of the hose housing with a strong force due to its weight, fire water pressure, etc. For this reason, there is a problem that the hose storage portion goes out to the outside than necessary.

  Therefore, for example, as in a fire hydrant device described in Japanese Patent Application Laid-Open No. 2003-38675 (Patent Document 1), a fire hose guide is provided, and the fire hose is brought into contact with the hose guide to extinguish the fire. There is one that gives a frictional resistance to the hose and suppresses the momentum of the fire hose coming out from the hose storage portion so that the fire hose does not come out more than necessary.

JP 2003-38675 A

  In a fire hydrant apparatus equipped with a hose guide as described above, in order to reliably suppress the momentum of the fire hose, the insertion hole of the hose guide through which the fire hose is inserted is made smaller, It is conceivable that the hose can be easily hit.

  However, if the insertion hole of the hose guide is made small and the fire hose is easy to hit, when the fire hose is stored in the hose storage part, it becomes a load and makes it difficult to return the fire hose. .

  In view of the circumstances described above, an object of the present invention is to provide a fire hydrant device including a hose guide that can be easily hit by a fire hose without reducing the insertion opening.

  The present invention provides a fire hydrant apparatus configured such that a fire hose is housed in an internal winding in a hose housing part inside a housing, and the fire hose is drawn out from an opening of the hose housing part. A hose guide having an insertion port through which the fire hose is inserted, the hose guide having a variable projection area of the insertion port with respect to the insertion direction of the fire hose. This is a fire hydrant device.

  Further, the present invention is the fire hydrant device, wherein the insertion port is defined by an insertion frame, and the insertion frame is rotatable in the front-rear direction.

  In the present invention, the insertion frame can be turned around a horizontal axis perpendicular to the insertion direction of the fire hose.

  Further, according to the present invention, the insertion frame can be rotated until the fire hose is sandwiched by a frictional force generated when the fire hose drawn out through the insertion port hits the insertion frame. This is a fire hydrant device.

  Further, the present invention is the fire hydrant device, wherein the hose guide has a rotation range adjusting means for adjusting a rotatable range of the insertion frame according to a force acting on the insertion frame. .

  Further, the present invention is the fire hydrant device, wherein the rotation range adjusting means adjusts a rotatable range of the insertion frame by using elasticity of an elastic body.

  In addition, the present invention is the fire hydrant apparatus, wherein the hose guide further includes a rotation prohibiting unit that prohibits the rotation of the insertion frame.

  According to this invention, by making the projection area of the insertion port of the hose guide variable with respect to the insertion direction of the fire hose, for example, the insertion frame that defines the insertion port can be rotated in the front-rear direction, and the projection area can be reduced. By making it variable, the projected area can be reduced, and the area where the fire hose can be inserted through the insertion port can be reduced, thereby reducing the opening area of the insertion port itself without reducing the opening area. The fire hose can easily hit the insertion frame of the hose guide that demarcates the hose guide.For example, when the insertion frame defining the insertion port is rotatable in the front-rear direction, the inner surface of the insertion frame is The fire hose can be easily hit by approaching the fire hose inserted through the insertion port while shifting back and forth.

  That is, according to the present invention, it is possible to provide a fire hydrant apparatus including a hose guide that can easily hit a fire hose without reducing the insertion opening.

  Further, according to the present invention, if the hose guide has the rotation range adjusting means for adjusting the rotatable range of the insertion frame according to the force acting on the insertion frame, for example, a fire hose When the force that acts on the insertion frame is large and the force acting on the insertion frame is large, the insertion frame is rotated so that the fire hose can easily hit the insertion frame. When the urging force is weak and the force acting on the insertion frame is not large, do not rotate the insertion frame (even if it is rotated, reduce the amount) so that the fire hose does not hit the insertion frame too much. And don't over-press the momentum.

  Further, according to the present invention, if the hose guide has a rotation prohibiting means for prohibiting the rotation of the insertion frame, for example, when the fire hose is stored in the hose storage portion, the rotation The prohibition means does not rotate the insertion frame, and does not reduce the area through which the fire hose can be inserted, so that the fire hose can easily pass through the insertion opening and the fire hose can be easily stored. be able to.

  An embodiment of the present invention will be described with reference to FIGS.

  The fire hydrant device 1 is installed in, for example, a road tunnel. The fire hydrant device 1 is a so-called internal winding type in which a fire hose 4 having a nozzle 4a at the tip is housed in an internal winding.

  As shown in FIG. 1, the fire hydrant apparatus 1 includes a hose housing portion 5 in which a fire hose 4 having a nozzle 4 a at the tip is housed in an inner winding in a housing 2, and illustration thereof is omitted. However, a fire hydrant valve and a pipe for supplying fire water to the fire hose 4 are also provided. An opening 2 a is provided in the front portion of the housing 2, and the opening 2 a can be opened and closed by a forward tilting door 3. An operation lever 6 of a fire hydrant valve is provided on the inner side 3a of the forward tilting door 3, and when the operation lever 6 is opened, the fire hydrant valve is opened and fire water is supplied to the fire hose 4 and discharged from the nozzle 4a. It has come to be. When the fire is extinguished, the operation lever 6 is opened with the nozzle 4a held, the fire hydrant valve is opened, the fire water is supplied to the fire hose 4, and the nozzle 4a is pulled to the place where the fire occurs. Go to fire extinguisher.

  The hose storage part 5 has an opening 5a at the front part, and the fire hose 4 can be pulled out from the opening 5a or stored inside.

  In the fire hydrant device 1, a hose guide 7 having an insertion frame port 7 a through which the fire hose 4 is inserted is provided on the inner side 3 a of the forward tilting door 3. The hose guide 7 has an insertion frame 7b that surrounds the insertion port 7a, a substantially Y-shaped shaft support portion 7c that supports the shaft portion 7i of the insertion frame 7b, and a support column portion 7g. It is attached.

  The fire hydrant device 1 has an insertion port 7a through which the fire hose 4 is inserted in the hose guide 7, so that when the fire hose 4 is pulled out, the fire hose 4 defines the insertion port 7a. By contacting the frame 7b and being given frictional resistance, the fire hose 4 can be prevented from coming out more than necessary.

  In the present embodiment, the hose guide 7 is provided on the inner side 3a of the forward tilting door 3 at substantially the same height as the lower portion of the hose storage portion 5, but if it is a position in front of the hose storage portion 5. For example, although not shown, it may be provided on the front surface of the hose storage portion 5, specifically on the front surface of the opening 5a. Further, the insertion frame 7b defining the hose guide 7 is an annular shape, but the shape is not limited to an annular shape, and may be various frame shapes, for example, a rectangular annular shape. Furthermore, the insertion frame 7b is not limited to an annular shape, and may have a partial opening.

  And the hose guide 7 can change the projected area of the insertion port 7a with respect to the insertion direction of the fire hose 4. The projected area of the hose guide 7 can be reduced so that the fire hose 4 at the insertion port 7a Although the area that can be inserted can be reduced, and the opening area of the insertion port 7a itself does not change, the fire hose 4 can be easily hit against the insertion frame 7b.

  Specifically, as shown in FIG. 2, the hose guide 7 has an insertion frame 7 b that defines an insertion port 7 a around a horizontal axis X orthogonal to the fire hose insertion direction A <b> 1 (shown in FIG. 3). It has a shaft support portion 7c that supports the shaft portion 7i that can be rotated. The insertion frame 7b can rotate in the direction A2 in which the lower portion 7e and the upper portion 7f move in the front-rear direction with respect to the shaft support portion 7c with the shaft portion 7i as an axis, as shown in FIG. In addition, when the fire hose 4 supplied with fire water is pulled out in the pull-out direction (front) A3, the fire hose 4 moves in the direction A3 while hitting the inner surface 7d of the insertion frame 7b. At this time, the fire hose 4 hits the lower part 7e in the vicinity of the inner surface 7d of the insertion frame 7b due to the weight of the fire hose 4 and the fire extinguishing water, and therefore the insertion frame 7b from the unrotated state of FIG. A force in the direction A4 that moves the lower 7e side forward and the upper 7f side rearward acts and rotates in that direction. Thereby, although the opening area of the insertion port 7a itself does not change, the upper portion 7f and the lower portion 7e are moved back and forth while approaching the fire hose 4 and the insertion port 7a with respect to the insertion direction A1 of the fire hose 4 into the insertion port 7a. 3a is smaller than the maximum projected area S1 in which the insertion frame 7b of FIG. 3A is not rotated from the magnitude of the force in the direction A4, the fire hose 4 is likely to hit the insertion frame 7b. It becomes a state. Here, as shown in FIG. 3B, the insertion frame 7b can be rotated until the upper portion 7f and the lower portion 7e are in contact with the fire hose 4 and are sandwiched from above and below, The projected area of the insertion port 7a with respect to the insertion direction A1 into the insertion port 7a of the fire hose 4 is reduced to the minimum projection area S2.

  In the present embodiment, the hose guide 7 is also rotatable in the A5 direction around the vertical axis as shown in FIG. For example, when the fire hose 4 is largely pulled out in the left and right direction, the fire hose 4 is rotated in the left and right direction following that, so that the fire hose 4 is pulled out in the left and right direction. Along the inner surface 7d, the fire hose 4 stays in the vicinity of the lower portion 7e by preventing the vicinity of the lower portion 7e from rising toward the upper portion 7f. As a result, the fire hose 4 is positioned near the lower portion 7e where the insertion frame 7b easily applies a force to rotate in the direction A2 about the axis X when the fire hose 4 is pulled out in any direction. For this reason, the fire hose 4 can be easily hit.

  Although the embodiment of the present invention has been described with reference to FIGS. 1 to 3, in this invention, the hose guide 7 is inserted into the insertion frame 7b according to the force acting on the insertion frame 7b when the fire hose 4 hits the insertion frame 7b. It is good also as what has a rotation range adjustment means which adjusts the range which can rotate 7b. If it has such adjustment means, for example, when the momentum of the fire hose 4 coming out is strong and the force acting on the insertion frame 7b is large, the insertion frame 7b is rotated to turn off the fire hose 4 When the insertion hose 4 is weak and the force acting on the insertion frame 7b is not large, the insertion frame 7b should not be rotated (turn Even if it is moved, the amount of the fire extinguishing hose 4 can be reduced, and the fire extinguishing hose 4 can be easily pulled out by preventing the fire extinguishing hose 4 from striking the insertion frame 7b and suppressing the momentum. .

  Specifically, for example, as shown in FIG. 4, the support portion 7 g integral with the shaft support portion 7 c of the hose guide 7 and the insertion frame 7 b are connected by an elastic body 7 h such as rubber or a spring, and FIG. As shown, an elastic body 7j such as rubber or a torsion spring is wound around a shaft part 7i of a shaft support part 7c of the hose guide 7, or a part of the shaft part 7i is formed of an elastic body 7j such as rubber or a torsion spring. Then, using these elastic bodies 7i, 7j as adjustment means, using their elasticity (restoring force), the fire hose 4 hits the insertion frame 7b according to the force acting on the insertion frame 7b, and the insertion frame 7b The pivotable range can be adjusted.

  Further, the hose guide 7 may include a rotation prohibiting unit that prohibits the rotation of the insertion frame 7b. If such a prohibition means is provided, it is possible to appropriately select whether to permit or prohibit the rotation of the insertion frame 7b. For example, when the fire hose 4 is stored in the hose storage portion 5, the rotation is prevented. The insertion frame 7b is not rotated by the movement prohibiting means, and the fire hose 4 can be easily passed through the insertion port without reducing the area through which the fire hose can be inserted in the insertion port 7a. It can be made easy.

  Specifically, for example, as shown in FIG. 6, a locking piece 7 k that can be rotated in the A6 direction and moved forward and backward in the rotation trajectory of the insertion frame 7 b is provided on the column portion 7 g of the hose guide 7. As shown in FIG. 7, the support rod 7g of the hose guide 7 is provided with a locking bar 7m that can be moved back and forth, and the locking bar 7m is inserted into the groove of the insertion frame 7b to rotate the insertion frame 7b. It is possible to appropriately select whether to allow or prohibit.

  Further, the direction of the axis X about which the hose guide 7 rotates can be appropriately selected in addition to the horizontal direction, and the shaft support method of the shaft portion 7i that can rotate around the axis X is also suitable for the position where the hose guide 7 is provided. It can be a method.

  In addition, the insertion frame 7b has been described as an example in which the insertion frame 7b can be rotated in the front-rear direction when the fire hose is pulled out, but the insertion frame 7b is rotated in advance so that the projection area becomes a predetermined area according to the installation site. It may be moved (tilted) and fixed.
