Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hose guide that guides a fire hose when the fire hose is pulled out of a fire hydrant device that is installed in, for example, a tunnel and houses a fire hose in an internally wound manner.
[0002]
[Prior art]
For example, a fire hydrant apparatus installed in a tunnel or the like is generally provided with a fire hose having a base connected to a fire extinguisher supply source and having a nozzle at the tip, and is discharged from the nozzle through the fire hose. It is used to extinguish a fire caused by a fire extinguisher. In a fire hydrant device provided with such a fire hose, the fire hose is normally wound and accommodated in the housing of the fire hydrant device, and is used by being pulled out from the housing in the event of a fire.
[0003]
In the fire hydrant apparatus as described above, there is a so-called internally wound fire hydrant apparatus in which the fire hose is wound and accommodated in a casing in an internally wound manner. This internally wound fire hydrant device is provided with a hose storage portion for storing a fire hose in a housing, and sequentially wraps the fire hose inside the hose storage portion from the outside toward the center. is there. Further, this internally wound fire hydrant device includes an opening for pulling out the fire hose from the hose storage part or storing the fire hose in the hose storage part on the front side of the hose storage part.
[0004]
[Problems to be solved by the invention]
In the internally wound fire hydrant device, when the operator pulls out the fire hose, the fire hose is wound upward by its own weight in addition to the force of the operator to pull out the hose. Force to fall from the side will also act (especially in the case of a fire hydrant device installed in a tunnel, the device may be installed at a height of about 70 cm from the road surface of the inner wall of the tunnel. Since the drop between the road and the road surface becomes large, the force that the hose tries to fall by its own weight is also large). For this reason, as a result, the fire hose may come out of the hose accommodating portion to the extent that the operator does not intend. A fire hydrant device that houses fire extinguishing hoses in the hose housing part can pull out the fire hoses from the hose housing part as much as necessary to perform fire fighting activities, so that the extra fire hose can interfere with the fire fighting activities. However, if the fire hose comes out to an extent not intended by the operator as described above, the advantage cannot be obtained.
[0005]
Therefore, it is conceivable to reduce the opening area of the opening portion of the hose accommodating portion. However, if the opening area is reduced, the fire hose is accommodated from the opening portion having a small opening area when the fire hose is accommodated in the hose accommodating portion. Therefore, the work becomes difficult.
[0006]
In view of the above circumstances, the present invention provides an internal fire hydrant device that can be operated when an operator pulls out the fire hose from the hose housing portion without reducing the opening area of the opening portion of the hose housing portion. The purpose is to be able to prevent the fire hose from coming out to the extent that the person does not intend.
[0007]
[Means for Solving the Problems]
To describe the present invention that achieves the above object, it includes a housing having a forward tilt door, a hose housing portion provided in the housing, in which a fire hose is housed in an inner winding, and a forward tilt of the housing. Provided on the inner surface of the door and has a hose insertion part through which the fire hose is inserted, and when the fire hose is pulled out, it comes into contact with the fire hose falling from the hose housing part and extinguishes by its frictional resistance. A fire hydrant device comprising a hose guide having a guide surface that restricts movement of the hose for use. According to this, when the fire hose is pulled out by the operator, the fire hose comes into contact with the guide surface of the hose guide provided on the inner surface of the forward tilt door of the fire hydrant device housing. Movement will be restricted. Therefore, even if the opening area of the opening portion of the hose accommodating portion is not reduced, that is, the opening area of the opening portion of the hose accommodating portion is secured to an area where the fire hose can be easily accommodated, to the extent that the operator does not intend. The fire hose can be prevented from coming out.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a top view of the essential part of the fire hydrant apparatus 1 in a state where the forwardly inclined door 20 is opened, and FIG. 2 is a front view of the hose guide 17.
[0009]
The fire hydrant device 1 is a so-called internally wound fire hydrant device that is installed in, for example, a tunnel or the like and that houses a fire hose 5 in an internal winding in a hose accommodating portion 22. This fire hydrant apparatus 1 includes a fire hose 5 having a nozzle 6 at the tip, a hose accommodating portion 22 for accommodating the fire hose 5 in an inner winding, and the like in a housing 30. The housing 30 has a front opening on the front side thereof, and includes a front inclined door 20 that allows the front opening to be opened and closed. The front inclined door 20 is opened to connect the fire hose 5 to the hose housing 22. so that the pull out opening 22a or al. The forwardly inclined door 20 has stop means (not shown) that stops the forwardly inclined door 20 in a horizontal position when opened. Further, the inner surface 20a of the front tilt door 20 has an insertion portion 23 through which the fire hose 5 is inserted, and a hose guide 17 having a guide surface 24 that comes into contact with the fire hose 5 when the fire hose 5 is pulled out. Is provided.
[0010]
The hose guide 17 spans two vertical bars 17c, 17c erected vertically on the inner surface of the forward tilting door 20, and the upper ends of the two bars 17c, 17c. It consists of a horizontal bar 17d provided so as to go in the horizontal direction with respect to the forward tilting door. That is, the hose guide 17 has a substantially U shape as a whole. The insertion portion 23 is formed inside the hose guide 17, and the guide surface 24 is formed on the inner surface of the hose guide 17. Further, the longitudinal bar-like bodies 17c and 17c and the lateral bar-like body 17d constituting the hose guide 17 have a circular cross section and are provided so as to be rotatable in the drawing-out direction of the fire hose 5. Further, the hose guide 17 is provided on a pedestal 21 that is rotatable in a horizontal direction with respect to the forward tilting door 20, and the hose guide 17 is rotated by the rotation of the pedestal 21. The rotating shaft 21 a of the pedestal 21 is embedded in the forward tilt door 20.
[0011]
The area of the insertion part 23 of the hose guide 17 is related to the size of the frictional resistance between the fire hose 5 and the guide surface 24 of the hose guide 17. The area can be appropriately limited by the guide 17.
[0012]
Since the hose guide 17 as described above is provided on the inner surface 20 a of the forward tilting door 20 of the fire hydrant device 1, when the operator pulls out the fire hose 5, the fire hose 5 comes into contact with the guide surface 24 of the hose guide 17. Will be pulled out. For this reason, the movement of the fire hose 5 is appropriately limited by the frictional resistance with the guide surface 24. Therefore, the hose guide 17 can prevent the fire hose 5 from coming out to an extent not intended by the operator.
[0013]
The hose guide 17 can be easily provided even with an existing fire hydrant device because the hose guide 17 need only be provided on the inner surface 20a of the forward tilting door 20.
[0014]
Further, the vertical bar-like bodies 17 c and 17 c and the horizontal bar-like body 17 d constituting the hose guide 17 are rotatable in the pulling-out direction of the fire hose 5. As a result, the frictional resistance between the fire hose 5 and the guide surface 24 of the hose guide 17 can be reduced, so that the movement of the fire hose 5 can be prevented from being excessively restricted by the hose guide 17. The hose 5 is not caught by the hose guide 17.
[0015]
Further, since the hose guide 17 is rotatable in the horizontal direction with respect to the forward tilting door 20, the hose guide is also rotated according to the pulling-out direction of the fire extinguishing hose 5. This also prevents the hose guide 17 from excessively restricting the movement of the fire hose 5.
[0016]
In the above description, the hose guide 17 is formed in a substantially U shape from the three rod-like bodies 17c, 17c, 17d, but it may be formed from a single rod-like body. Further, the hose guide 17 may be constituted by only two vertical bar-like bodies 17c and 17c. In the above description, the three rod-like bodies 17c, 17c, and 17d are rotatable in the pulling-out direction of the fire hose 5, but they may not be rotated depending on the degree of frictional resistance. Further, in the above to form a hose guide 17 from a circular cross section of the rod-like body, which a good servants to form a plate-like body (although the surface of the case insertion portion 23 side, i.e. the guide surface 2 4 formed It is better to chamfer so that there are no edges on the surface.) In the above description, the hose guide 17 is provided on the rotatable pedestal 21 to be rotatable. However, the hose guide 17 may not be rotated depending on the degree of frictional resistance. The hose guide 17 is preferably installed at a position corresponding to the central space portion of the internal hose 5 of the fire-extinguishing hose 5 accommodated in the hose accommodating portion 5. In this way, even if the hose guide 17 is erected on the inner surface 20a of the forward tilt door 20, the hose guide 17 is accommodated in the hose accommodating portion 22 when the forward tilt door 20 is closed. Since the inner space can be accommodated in the inner space, the depth of the fire hydrant device 1 can be reduced. Further, depending on the position, a hoisting means for the hose guide 17 may be provided so that the hoisting door 20 can be raised and lowered. Also by this, the depth of the fire hydrant device 1 can be reduced.
