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, a fire hydrant device described in Japanese Patent Application Laid-Open No. 2007-330713 (Patent Document 1) includes a hose guide that gives a frictional resistance to the fire hose when it comes into the opening of the hose housing. The momentum that the fire-extinguishing hose comes out of the hose storage portion can be suppressed.

JP 2007-330713 A

  However, as in the case of the hose guide described in Patent Document 1, in the case where a member that gives a frictional resistance to the fire hose is provided in the opening of the hose housing, the fire hose is stored in the hose housing. It is necessary not to get in the way, and the member needs to be provided with an attaching / detaching mechanism, a moving mechanism, etc., and the structure becomes complicated.

  In view of the above circumstances, an object of the present invention is to obtain a fire hydrant device that can suppress the momentum of the fire hose coming out of the hose housing portion when the fire hose is pulled out by a simple structure. .

The present invention relates to a fire hydrant device in which a fire hose is housed in an internal winding in a hose housing part inside a housing, and the opening edge of the opening part is sawed in the fire hydrant device having an opening part through which the fire hose is drawn out. A fire hydrant device characterized by being formed in a blade shape .

Further, the present invention is the fire hydrant device , wherein the opening edge includes a horizontal portion and an inclined portion continuous therewith.

  According to the present invention, when the fire hose is pulled out, the fire hose in a state where fire water is supplied comes out from the opening of the hose housing portion while hitting the opening edge, but the opening edge has a concave portion. By being formed, or by having the opening edge formed in a concavo-convex shape, a wave shape or a saw blade shape, while hitting a concave portion or a wavy or saw blade valley portion of the opening edge. Because it will come out, the momentum of the fire hose coming out from the opening can be attenuated, the momentum can be suppressed, so that the fire hose does not come out of the hose storage part more than necessary can do.

  Further, according to the present invention, as described above, the momentum of the fire extinguishing hose coming out from the hose accommodating portion can be suppressed, but unlike the conventional example, the extinguishing hose is accommodated in the hose accommodating portion. In this case, since there is no member that obstructs that, there is no need to provide an attaching / detaching mechanism, a moving mechanism, or the like that is necessary if such a member is provided.

  Therefore, according to this invention, when the fire hose is pulled out, the momentum of the fire hose coming out of the hose housing portion can be suppressed with a simple structure.

  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 back surface of the forward tilting door 3, and when the operation lever 6 is opened, fire water is supplied to the fire hose 4 and discharged from the nozzle 4a. Yes. 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 addition, the hose accommodating part 5 is specifically provided so that it may go to the back surface of the housing | casing 2 from each of a pair of rod-shaped body 5c provided so that it might go up and down of the housing | casing 2, and a pair of rod-shaped body 5c. The substantially L-shaped band plate 5d and the upper surface, the lower surface, and the rear surface of the housing 2 are formed. The opening 5a is formed between the pair of rod-shaped bodies 5c, and the opening edge of the opening 5a 5b is formed in the side part which a pair of rod-shaped body 5c opposes.

  And in the hose accommodating part 5, the opening edge 5b of the orthogonal | vertical direction of the opening part 5a is made into the shape containing the recessed part 5e which makes the concave shape shown in detail after FIG. 2 by the front view (henceforth front view) of the fire hydrant apparatus 1 It has been formed. The number and size of the recesses 5e can be appropriately determined according to how much the fire extinguishing hose 4 attenuates the momentum coming out of the opening 5a.

  About the shape of the opening edge 5b of this opening part 5a, if it is a shape containing the recessed part 5e, it can be set as various shapes. For example, the concave portion 5e may be formed in the opening edge 5b in various shapes in front view, but a plurality of convex portions 5f may be formed in various shapes in the opening edge 5b in front view. The recess 5e can be formed in various shapes.

  Specifically, as shown in FIGS. 1 and 2, a plurality of convex portions 5f formed by a horizontal portion 5g and an inclined portion 5h continuous therewith are formed on the opening edge 5b in front view, and a concave portion 5e is formed therebetween. In other words, the opening edge 5b can be formed into a saw blade shape (the size of each of which can be changed), and a recess 5e can be formed in the valley portion. As shown in FIG. 3, a plurality of convex portions 5f formed by the first inclined portion 5i and the second inclined portion 5j that are linearly continuous with different inclination directions when viewed from the front are formed on the opening edge 5b, In other words, the opening edge 5b is formed into a wave shape, specifically, a triangular wave shape (the size of each may be changed), and the recess portion 5e is formed in the valley portion. 4 and FIG. As shown in the figure, a plurality of convex portions 5f formed by a first curved surface portion 5k and a second curved surface portion 5m that are continuously curved in different inclination directions when viewed from the front are formed on the opening edge 5b, and a concave portion 5e is formed therebetween. In other words, the opening edge 5b is formed into a wave shape, specifically a sine wave shape (the size of each may be changed), and a recess 5e is formed in the valley portion. It can be.

  The wave shape of the opening edge 5b may be a rectangular wave shape (the size of each of which may be changed) in front view as shown in FIG. As shown in FIG. 5 (b), the convex portion 5f may be intermittently provided via a vertical portion 5n, and in this case, the vertical portion 5n has a constant length and is intermittently provided. Alternatively, the length of the vertical portion 5n may be changed and intermittently interrupted.

  As described above, the fire hydrant apparatus 1 has the opening edge 5b of the hose storage portion 5 formed in a shape including the recess 5e, so that the fire hose 4 in a state where fire water is supplied is removed from the hose storage portion 5. When the fire hose 4 is pulled out, the fire hose 4 tends to extend straight so that the inner winding diameter of the fire hose 4 increases due to the pressure of the fire water. 5 is pressed against the upper surface, the lower surface, and the rear surface of the casing 2 and when it passes through the opening 5a, it is pressed against the opening edge 5b. At this time, the fire hose 4 enters the recess 5e as shown in FIGS. 2B, 3B, 4B, 5A, and 5B, and there The fire extinguishing hose 4 comes out from the opening 5a at that stage, and the momentum coming out from the opening 5a is attenuated and the momentum can be suppressed. Yes. Therefore, it is possible to prevent the fire hose 4 from coming out of the hose storage part 5 more than necessary. If the opening edge 5b is covered with a material having a high friction coefficient, the momentum of the fire hose 4 can be further attenuated.

  Further, as described above, the fire hydrant device 1 is configured such that the momentum of the fire hose 4 coming out of the opening 5b is attenuated to suppress the momentum, but the opening edge 5b of the hose storage portion 5 is suppressed. The momentum of the fire extinguishing hose 4 can be restrained by the fact that the momentum of the fire extinguishing hose 4 can be restrained, but there is no member that obstructs the housing of the fire extinguishing hose 4 in the hose accommodating portion 5. If there is such a member, there is no need to provide an attaching / detaching mechanism, a moving mechanism, or the like.
