[Industrial application fields]
The present invention relates to a fire hydrant device.
[0002]
[Prior art]
Conventional fire hydrant devices for so-called tunnels include a fire extinguisher storage section for storing a fire extinguisher, a fire hydrant storage section for storing a fire hose with a nozzle provided at the tip, and electrical devices such as transmitters and indicator lights. When viewed from the front, the fire extinguisher storage part is located on the side of the fire hydrant storage part, and the electrical equipment part is on the side of the fire hydrant storage part above the fire hydrant storage part. Are arranged, and are configured to be rectangular as a whole. As the height of the entire fire hydrant device, the height of the fire hydrant storage part and the electrical equipment part is the height of the fire hydrant storage part. A plurality of electric wires such as a power source and various signal lines are drawn into and connected to the electric equipment section.
[0003]
[Problems to be solved by the invention]
In the configuration of the fire hydrant device as described above, the electric wire is drawn from one of the left and right sides of the fire hydrant device, but is usually drawn from the same direction as the drawing of the water supply pipe of the fire hydrant device. The direction of the water supply pipe is fixed on the right side, and when the electric equipment part is provided on the left side, wiring is performed so as to penetrate the entire fire hydrant device from the right side. Due to the recent demand for miniaturization, it is difficult to secure the space even for electric wires.
[0004]
In particular, when a hose is housed in a so-called inner-wound type in the fire hydrant storage part, if the hose storage part is wound using the entire cross-section of the fire hydrant device, the electric wire cannot be passed, and the drawing direction can be changed or the housing It is necessary to take measures such as passing outside.
[0005]
Further, when the fire hydrant device is provided on the wall surface in a tunnel, for example, if the height is raised from the floor surface, the overall position becomes high, and for example, it becomes difficult to take out the fire extinguisher or inspect electrical equipment.
[0006]
Accordingly, an object of the present invention is to simplify the wiring of electric wires or to maintain the operability of each part.
[0007]
[Means for Solving the Problems]
In view of the above, the present invention is, in a housing provided with a door on the front, housing a hose having a nozzle, the fire hydrant apparatus for supplying extinguishing water to said nozzle, the inner wall upper surface of the housing and the inner wall lower surface and A hose is wound on the inner wall using the back of the inner wall , and the hose is housed in the inner volume, and the hose housing section traverses the hose housing section from side to side along the upper or lower surface of the housing. A wire crossing path is formed. [0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the front of the fire hydrant device, and FIG. 2 shows the entire fire hydrant device using it. In FIG. 2, a fire hydrant device 100 is a so-called inner wrap type fire hydrant device in which a fire hose is housed in an inner volume. The fire hydrant device 100 is installed on, for example, an inspection road adjacent to a roadway in the tunnel, or is embedded in an inner wall of the tunnel.
[0011]
Such a fire hydrant apparatus 100 is divided into a fire hydrant storage part 100a, an electric equipment part 100b, and a fire extinguisher storage part 100c. The fire hydrant storage part 100a has a fire-extinguishing nozzle 30 at its tip in the housing 101. A hose 104 having a hose 104 in the inner volume, a fire water supply pipe 106, a three-way switching valve 107, a pressure regulating valve 108, a fire hydrant valve 109, a fire hydrant 110, and the like. .
[0012]
An opening 105 a for pulling out the hose 104 from the hose storage unit 105 and storing the hose 104 in the hose storage unit 105 is provided on the front surface of the hose storage unit 105. Is provided with a fire hydrant opening 101 a that exposes the opening 105 a of the hose storage part 105 to the outside of the housing 101.
[0013]
The hose 104 is made of a so-called fiber-shaped cylindrical woven fabric with a rubber-lined lining formed inside, and the surface is further teflon processed to give durability and wear resistance. At the same time, the coefficient of friction is reduced. This Teflon layer has a remarkably smaller friction coefficient than a hose in which cloth or rubber is exposed on the surface, and the effect is exhibited as it needs to be pulled longer. The Teflon processing is laminated on the surface of the hose 104 by spray painting or the like, but may be coating by attaching a film or the like. A material having a small friction coefficient other than Teflon may be selected. Further, the main hose may be a cloth alone or a rubber hose.
[0014]
Further, the hose 104 having an inner diameter of 30 mm to 38 mm, for example, 38 mm, is used, and is thinner than the conventional one. Therefore, the weight of water is reduced by the square of the inner diameter ratio, and this is compared with the frictional force. Sometimes, the pulling force is reduced in proportion to the weight, so that the operability as a fire hydrant device is improved. Moreover, the space of the hose accommodating part 105 which accommodates such a hose 104 can also be made small compared with the past.
[0015]
The hose storage portion 105 is formed from a hose bucket 112. The hose bucket 112 includes two rod-shaped bodies 113 extending from the upper surface of the inner wall of the housing 101 to the lower surface of the inner wall, and two sheets bent in a substantially L shape extending from the two rod-shaped bodies 113 to the rear surface of the inner wall of the housing 101. An opening 105a is formed between the two rod-shaped bodies 113. Further, corner openings 113a are provided at the four corners between the two strips 114 of the hose bucket 112 and the inner wall upper surface and the inner wall lower surface of the housing 101. As described above, the hose bucket 112 uses the inner wall of the housing 101, so that the hose housing portion 105 can be downsized as compared with the case where the hose housing portion 105 is formed inside the housing 101 by a box shape. And, as a result, the fire hydrant device 100 can be reduced in size, and how the corner opening 113a can be used when the hose 104 is stored in the hose bucket 112 from the opening 105a of the hose bucket 112. Whether the hose 104 is wound can be visually confirmed, and the hose 104 can be pushed in and adjusted by putting the hand into the hose bucket 112 from the corner opening 113a. Can be easily performed.
[0016]
Furthermore, a duct 51 is formed at the upper end of the hose bucket 112 constituting the hose storage unit 105 as a wire crossing path that passes through the housing 101 from side to side. In this duct 51, a substantially L-shaped partition plate 52 is disposed so as to form a space on one surface with respect to the upper surface of the housing 101, and as shown in FIGS. On the other hand, the bent portion 52b abuts on the upper surface of the housing 101 to form a space, and the hose 104 accommodated in the hose bucket 112 is wound in contact with the flat portion 52a of the partition plate 52. become. Without the partition plate 52, the hose 104 is stored in a state where the hose 104 is wound from the back side of the casing 101 to the front surface in order, and there is no space for the wires to cross. It becomes possible to pass an electric wire simply by forming. The partition plate 52 is one surface with respect to the hose storage portion 105 up to the rod-like body 113 so as not to affect the state of the hose 104 being caught, but may be up to the middle if the duct 51 can be formed. Further, as shown in FIG. 5, the same state as the hose 104 may be formed by using a pipe 55 having the same diameter as the hose 104. Such a duct 51 may be provided on the lower surface side instead of the upper surface side of the housing 101, and the width of the duct 51 only needs to be dimensioned across the hose storage portion 105.
[0017]
The casing 101 is provided with a forward tilting door 6 whose upper edge side opens forward with the lower edge of the hydrant opening 101a as a fulcrum as a front door that allows the hydrant opening 101a to be opened and closed. The forwardly inclined door 6 is provided with, for example, a stopper so as to stop at a substantially horizontal position in the opened state, and a buffer mechanism is provided for the opening operation by a damper or the like.
[0018]
The forward tilt door 6 is provided with a door built-in mechanism portion 6a inside, and a back plate 7 covering the door built-in mechanism portion 6a is provided on the back surface 6b side of the forward tilt door 6. As the door built-in mechanism portion 6a, for example, there is a latch mechanism portion (not shown) for opening and closing the forward tilting door 6, and a mechanism for transmitting power of the opening / closing lever 10 as an opening mechanism of the fire hydrant valve 109. A storage recess 8 is provided on the back surface 6 b side of the forward tilt door 6 at a position facing the opening 105 a of the hose storage portion 105 when the forward tilt door 6 is closed. The slack portion 104b of the hose 104 can be accommodated while holding the nozzle 30 on the surface. Thereby, there is no possibility that the nozzle 30 and the hose 104 are caught between the forward tilting door 6 and the hose storage portion 105, so there is no need to provide a large gap.
[0019]
Further, the nozzle 30 has a straight cylindrical body 31 having a water discharge port at the tip thereof, a rectangular tube body 32 in which the distal end connecting portion 104a of the hose 104 is connected to the base portion 32b, and the cylindrical bodies 31, 32. And a gripping portion 38 that protrudes substantially perpendicularly from the cylindrical body 31 for operability. The nozzle 30 is placed sideways along the upper side with respect to the forward tilting door 6, supported by the nozzle support portion 103, and stored in the storage recess 8. At this time, since the base portion 32b of the cylindrical body 32 can be directed to the opening portion 105a of the hose housing portion 105 by the rotation connecting portion 33, the slack portion 104b of the hose 104 does not need to be greatly curved, and as a result, the nozzle The fire hydrant device 100 can be made small by the overall arrangement without limiting the installation position of the support portion 103.
[0020]
Next, in the fire extinguisher storage portion 100c, normally two fire extinguishers (not shown) are provided on the lower surface of the inner wall of the casing 101. A fire extinguisher door 6c that opens sideways with the left side as a fulcrum is provided as a front door that allows the fire extinguisher opening to be opened and closed in order to allow the fire extinguisher to be inserted and removed freely. The fire extinguisher door 6c is not shown in detail so as to maintain an open state when the fire extinguisher is exchanged, but is provided with a holding rod, which can be transferred from the housing 101 to the fire extinguisher door 6c side. The position of the fire extinguisher door 6c can be fixed. The height of the fire extinguisher storage portion 100c is substantially constant based on the height of the built-in fire extinguisher, and cannot be reduced more than necessary. On the other hand, the height of the fire hydrant storage part 100a is based on the height of the hose storage part 105, but when the hose storage part 105 is internally wound, the lateral width is deformed with respect to the height. To some extent. Therefore, in this fire hydrant apparatus 100, the height of the fire hydrant storage part 100a is adjusted to the height of the fire extinguisher storage part 100c, and by disposing the electrical device part 100b described later between the parts, the parts are almost side by side. There is no problem in the operability due to the installation height of the apparatus 100, and construction on site is easy to perform.
[0021]
Furthermore, in the electrical equipment unit 100b, as shown in FIG. 1, a mounting plate 81 is attached to the front portion of the housing 101 between the fire hydrant storage unit 100a and the fire extinguisher storage unit 100c by screwing at four corners. As an apparatus, an indicator lamp 82 for indicating the position of the fire hydrant device 100, a transmitter 83 for urgent notification when an accident or the like occurs, a response lamp 84 for indicating whether or not there is a response to transmission when using the transmitter 83, and A telephone jack 85 used for calling a disaster prevention center (not shown) at the time of inspection or the like is mounted. In addition to these, an emergency outlet and a speaker may be combined, and it is not necessary to have all the above devices.
[0022]
The mounting plate 81 can be attached to and detached from the housing 101, and the work can be easily performed in the case of attachment of each device during manufacturing and maintenance inspection. Since the electric devices are arranged in the vertical direction on the mounting plate 81, they are efficiently arranged with respect to the overall height of the fire hydrant device 100, which contributes to downsizing of the entire device 100. Further, on the back side of the mounting plate 81, a terminal block 86 is provided in which a power source and a signal line are connected to each device. An electric wire passed between the fire hydrant devices 100 such as in a tunnel is connected to each device by being drawn from one of the housings 101 and connected to the terminal block 86. In many cases, the wire drawing into the housing 101 is arranged in the same manner as the water supply pipe. In any case, when the wire is drawn into the right side of the housing 101, the wire is routed to the terminal block 86 through the duct 51 of the fire hydrant storage portion 100a. Therefore, in this embodiment, the terminal block 86 can be easily wired regardless of where the casing 101 is drawn. The mounting plate 81 is screwed at the four corners, but other mounting methods may be used, and the number of screws may be omitted by using a hook.
