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 hose in which a fire hose is inserted inside a forward tilt door that tilts and opens and closes the front surface of the device housing. There is a guide attached and a fire hose is brought into contact with the hose guide to give friction resistance to the fire hose so that the fire hose does not come out more than necessary.

  However, if the hose guide is attached to the forward tilt door, the weight of the forward tilt door will increase accordingly, so the conventional fire hydrant device is equipped with a hose guide so that the forward tilt door can be opened and closed accordingly. The necessary force was getting bigger.

  In the conventional fire hydrant device, the hose guide is a dedicated member for preventing the fire hose from coming out more than necessary.

  In view of the above circumstances, the present invention does not increase the force required to open and close the forward tilt door even if a hose guide that can prevent the fire hose from coming out of the hose storage portion more than necessary is provided. It aims at providing the fire hydrant apparatus which can be made.

  Another object of the present invention is to provide a fire hydrant device that can be manufactured at low cost by combining the hose guide and the forward tilting door holding means.

  The present invention is configured such that a fire hose is housed in an internal winding in a hose housing portion inside a housing, a forwardly inclined door provided on the front surface of the housing is opened, and the fire hose is pulled out. In the fire hydrant apparatus, a hose guide having an insertion portion through which the fire hose is inserted, the fire hydrant apparatus being provided with a hose guide locked to the housing and the forward inclined door. is there.

Two connection bodies to be stopped, and two connection bodies that are provided between the two connection bodies, connect the two connection bodies, and form the insertion portion, and The hose guide is a fire hydrant device in which at least one of the two connecting bodies is movably provided.

  According to the present invention, since the hose guide is locked to the housing and the forward tilt door, the weight of the hose guide is applied to the housing and can be prevented from being applied to the forward tilt door. It has an insertion part through which the hose is inserted and has a hose guide that can give a frictional resistance to the fire extinguishing hose coming out of the hose storage part, so that the weight of the forward tilt door can be prevented from increasing. .

  Therefore, according to the present invention, even if a hose guide that can prevent the fire hose from coming out of the hose storage portion more than necessary is provided, the force required to open and close the forward tilt door does not increase. can do.

  Further, according to the present invention, if the hose guide constitutes a means for holding the opening degree of the forward tilt door, the opening degree of the forward tilt door is obtained by combining the hose guide and the forward tilt door holding means. Therefore, it is not necessary to separately provide a means for maintaining the opening degree of the forward tilt door, so that the fire hydrant apparatus can be manufactured at low cost.

  Further, according to the present invention, if the hose guide is at least partially formed of a flexible member, the hose guide can be folded without providing a folding mechanism. Even if the fire hose is pulled in a direction that bends and is strongly pressed against the hose guide, the hose guide deforms and absorbs the force that the fire hose is strongly pressed against. This can be mitigated so that the fire hose can be prevented from bending.

  Further, according to the present invention, if the hose guide is removable with respect to the housing and the forward inclined door, and the hose guide has the insertion portion at an asymmetrical position in the vertical direction, the hose guide is moved up and down. On the contrary, the insertion part can be positioned downward or conversely upward. For example, when pulling out the fire hose, the insertion part is positioned downward and the weight of the fire hose is used. The fire hose can be easily pulled out, and when the fire hose is stored, the insertion part is positioned upward, and the weight of the fire hose can be used to make it easier to store the fire hose in the hose storage part. can do.

It is a figure equivalent to FIG. 1 in the state which showed embodiment same as the above and has located the insertion part of the hose guide upward. It is a figure which shows other embodiment and is equivalent to FIG. Furthermore, other embodiment is shown and both (a) and (b) are perspective views of a hose guide.

  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 extinguishing water is supplied to the fire hose 4 and discharged from the nozzle 4a. ing. 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.

  The fire hydrant apparatus 1 is provided with a hose guide 7 having an insertion portion 7a through which the fire hose 4 is inserted, and is engaged with the housing 2 and the forward tilting door 3. .

  Here, when extinguishing, when the fire hose 4 is not pulled out from the hose housing part, the fire hose 4 tends to extend straight so that the inner diameter of the fire hose 4 is widened by the pressure of the fire fighting water. It is pressed against the wall and is stationary. However, in order to pull out the fire hose 4, if any force is applied to the fire hose 4 from the inside of the hose storage portion 5 toward the opening 5 a, the fire hose 4 will be As it tries to extend straight from the inside of 5 toward the opening 5a, it protrudes from the opening 5a more than it is pulled out. However, the fire hydrant apparatus 1 has the insertion portion 7a through which the fire hose 4 is inserted so that the fire hose 4 contacts the hose guide 7 when the fire hose 4 is pulled out. By giving the frictional resistance, the fire hose 4 can be prevented from coming out of the hose storage portion 5 more than necessary. Further, since the hose guide 7 is locked to the housing 2 and the forward tilting door 3, the weight of the hose guide 7 is applied to the housing 2 and does not reach the forward tilting door 3. Although the guide 7 is provided, the weight of the forward tilt door 3 does not increase, and the force required to open and close the forward tilt door 3 does not increase.

  Specifically, the hose guide 7 is located between the housing 2 and the forward tilting door 3, one end 7b is locked to the front surface 2b of the housing 2, and the other end 7c is tilted forward. Two connecting members 7d that are locked to the inner side 3a of the door 3, and the two connecting members 7d that are provided between the two connecting members 7d are connected in the lateral direction, and an insertion portion 7a is formed. Two connected bodies 7e. That is, in the example shown in FIGS. 1 to 3, the hose guide 7 has a substantially ladder shape.

  In the present embodiment, the hose guide 7 is formed of a hard member such as a metal, but each of the two connecting bodies 7d is provided with a folding mechanism portion 7f. It can be folded up and down with the portion 7f as a fulcrum, and can be stored in a folded state by closing the forward tilting door 3, and can be kept stretched by opening the forward tilting door 3. It is like that.

  Further, the hose guide 7 is locked to the housing 2 and the forward tilting door 3, so that it can be used as means for holding the forward tilting door 3 at a predetermined opening. In the present embodiment, the hose guide 7 can hold the opening degree of the forward tilting door 3 when the forward tilting door 3 is opened and stretched. It is what constitutes.

  In the fire hydrant apparatus 1, the hose guide 7 has a purpose of preventing the fire hose 4 from being unnecessarily removed, but also has a purpose of maintaining the opening degree of the forward tilting door 3 as described above. There is no need to separately provide a means for maintaining the opening degree of the forward tilting door 3. That is, the hose guide 7 and the holding means for the forward tilting door 3 can be used in common, so that the number of members can be reduced and the production can be made inexpensive.

  Further, the hose guide 7 can be detached from the housing 2 and the forward tilting door 3, and the insertion portion 7a is not located in the position where the insertion portion 7a is biased toward the end portion 7c (the forward tilting door 3 side), that is, in the vertical direction. It is in the control position.

  Accordingly, the fire hydrant device 1 may be arranged so that the hose guide 7 is turned upside down depending on the method of use and the insertion portion 7a is positioned closer to the lower front tilt door 3 as shown in FIG. As shown, it can be positioned closer to the upper housing 2, for example, when the fire hose 4 is pulled out, as shown in FIG. The fire hose 4 can be easily pulled out by using the weight of the fire extinguisher. When the fire hose 4 is stored, the insertion portion 7a is positioned upward as shown in FIG. Thus, the fire hose 4 can be easily housed in the hose housing portion 5 by dropping the fire hose 4 into the hose housing portion 5.

  In the hose guide 7, the two connecting bodies 7e are connected to the two connecting bodies 7d by, for example, screwing, locking by hooks, insertion into the recesses provided in the two connecting bodies 7d, or the like. By being configured to be detachably attached, any of them can be moved in the vertical direction. Thereby, when only one connection body 7e is movable, the opening degree (inner area) of the insertion part 7a can be changed. For example, if the opening degree of the insertion part 7a is increased, the fire is extinguished. This is convenient for checking the hose 4 for use. In addition, when both the connecting bodies 7e are movable, in addition to being able to change the opening degree of the insertion portion 7a, it is possible to change the vertical position thereof, for example, As described above, even when the hose guide 7 is not turned upside down, when the fire hose 4 is pulled out, as shown in FIG. 1, the insertion portion 7a is positioned downward and the weight of the fire hose 4 is used. Thus, the fire hose 4 can be easily pulled out, and when the fire hose 4 is stored, the fire hose 4 can be used by placing the insertion portion 7a upward and using the weight of the fire hose 4 as shown in FIG. 4 can be dropped into the hose storage part 5 so that the fire hose 4 can be easily stored in the hose storage part 5.

  In the embodiment shown in FIGS. 1 and 2, the hose guide 7 is formed of a hard member made of metal or the like. However, as shown in FIG. 3, the hose guide 7 is made of a flexible member such as silicon. It may be formed of rubber, neoprene rubber, butyl rubber, nitrile rubber, urethane elastomer, natural rubber or fluorine rubber, or a spring.

  By forming the hose guide 7 from a flexible member, the hose guide 7 can be folded without a folding mechanism, and the fire extinguishing hose 4 is bent with the portion that contacts the hose guide 7 as a fulcrum. Even if the hose guide 7 is strongly pressed against the hose guide 7, the hose guide 7 is deformed to absorb the force by which the fire hose 4 is pulled, and the force applied to the fire hose 4 can be reduced. Therefore, it is possible to prevent the fire hose 4 from being bent. The hose guide 7 may be formed of a deformable member similar to a flexible member, such as a chain in which a plurality of rings are connected. Moreover, when the hose guide 7 is a hard member made of metal or the like, the hose guide 7 may cover a flexible member.

  Further, the shape of the hose guide 7 is not limited to the ladder shape as shown in FIGS. 1 to 3. For example, as shown in FIG. It is good also as what has one rod shape or a string-like body, and has the cyclic | annular or spiral insertion part 7a in the middle. Also in this case, the hose guide 7 can be formed of a flexible member.

  Further, the hose guide 7 is provided with a shock absorber by a spring such as a hydraulic damper or a leaf spring when the forward tilting door 3 is opened and when the hose guide 7 is extended from the folded state. In the case of an extended or flexible member, if the member itself extends slowly, it can also function as a hydraulic shock absorber that has been conventionally employed so that the forwardly inclined door 3 does not open suddenly. .
