Description

The present invention relates to a fire hydrant device that opens a fire hydrant door by operating a handle device and draws out a hose with a water discharge nozzle to discharge water.

  Conventionally, a fire hydrant device has been installed in a tunnel such as an automobile road in preparation for a fire.

  FIG. 8 is a front view of a conventional fire hydrant device 100, FIG. 9 is a plan view of the internal structure of the fire hydrant device 100 with the fire hydrant door 104 open, and FIG. 10 is a side view thereof. A fire hydrant door 104 and a fire extinguisher door 106 are provided on the front surface of the housing 102 of the fire hydrant apparatus 100.

  The fire hydrant door 104 is provided with a handle. The lock can be released by pulling the handle toward the front, and the lower side of the fire hydrant door 104 can be opened forward with the rotating shaft. Further, a buffer damper 108 is provided between the hydrant door 104 and the housing 102 so that the hydrant door 104 can be opened smoothly.

  Inside the fire hydrant door 104, a hose 112 fitted with a nozzle 110 at the tip is housed in a hose bucket 116 in the housing. The hose 112 is accommodated in the hose bucket 116 through a hole opened in the side plate of the hose bucket 116. In the hole, the hose 112 enters the hose bucket 116 through the protective tube 112a to prevent the hose 112 from rubbing and scratching the hose surface when the hose 112 is pulled out.

JP 2005-318972 A

  However, in such a tunnel hydrant apparatus, the nozzle 110 and the hydrant valve opening / closing lever 114 are arranged inside the hydrant door 104, so that a large space for fully opening the hydrant door 104 is provided in front of the apparatus. There is a problem of need.

  In addition, the fire hydrant door 104 is opened and the hose 112 is pulled out by the nozzle 110 to discharge water, and then the hose 112 is rewound into the hose bucket 116. Ride and work. Also, in the inspection work for checking the valves of the fire hydrant device, the inspection worker gets on the open fire hydrant door 104 and works. For this reason, the fire hydrant door 104 has a robust structure capable of withstanding the weight when an operator gets on. Therefore, the weight of the fire hydrant door increases, and the work of closing the fire hydrant door becomes difficult.

  In order to solve this problem, the inventors of the present application moved the nozzle and the hydrant valve opening / closing lever provided inside the hydrant door to the housing side, and the nozzle and the hydrant valve opening / closing lever are not arranged on the hydrant door, A fire hydrant device in which the door is reduced in size and weight has been proposed (Japanese Patent Application No. 2008-140696).

  In this fire hydrant device, a fire hydrant valve opening / closing lever is provided directly on the fire hydrant valve, and the opening / closing operation is performed by moving the fire hydrant valve opening / closing lever in the vertical direction.

  However, in a fire hydrant device that opens and closes by operating the hydrant valve opening / closing lever provided on the hydrant valve vertically, the fire hydrant valve opening / closing lever in the housing is moved to the upper closed position with the fire hydrant door closed, for example. The fire hydrant valve is closed, but after the fire hydrant device is installed in the tunnel, the fire hydrant valve open / close lever in the upper closed position moves naturally in the opening direction when subjected to vibrations such as a vehicle or an earthquake. there is a possibility.

  In order to solve this problem, it is sufficient to provide a lock mechanism on the hydrant valve opening / closing lever, but it is necessary to open the hydrant door and release the lock with the nozzle hose pulled out. In the event of an emergency such as a fire, requiring the user to perform an operation of unlocking may cause the operability to be significantly impaired because the fire hydrant valve cannot be opened to discharge water if it takes time to unlock.

The present invention provides a fire hydrant device having a structure in which a fire hydrant valve opening / closing lever is held in a closed position and does not move in the opening direction due to vibration or the like when the fire hydrant door is closed without requiring an unlocking operation or the like. The purpose is to do.

  FIG. 2 is a front view showing the internal structure of the embodiment of FIG. 1 with the fire hydrant door on the first housing 12-1 side removed and the maintenance door 22 opened upward and supported by a stay 27. In FIG. 2, a hose storage space 36 is formed on the left side of the first casing 12-1, and a valve storage space 38 is formed on the right side.

  The hose storage space 36 is arranged in a bucket frame 40 in which frame pipes are arranged vertically in the horizontal direction, forming a hose storage space inside. The bucket frame 40 is bent so that one pipe has a U-shape when viewed from the front and a horizontal L-shape when viewed from the plane, and the upper and lower pipe ends on the left side are formed on the left side surface of the first housing 12-1. It is fixed to the inner wall surface, and the right bent end is fixed to the inner wall surface on the rear surface of the housing by a frame holder 45.

  Two hose guides 42 are fixed in the center of the bucket frame 40 in the vertical direction, and a hose outlet is formed therein. When pulling out the hose 44, the hose guide 42 prevents the inner hose 44 from collapsing or rubbing against the door opening 16 to damage or break the hose 44.

  A hose 44 is housed inside the hose storage space 36 surrounded by the bucket frame 40 and the inner wall of the housing. Here, a hose connection port 46 is disposed in the lower portion of the right valve storage space 38, and after the primary side of the hose 44 is connected to the hose connection port 46, the hose 44 is wound into the hose storage space 36. However, in this case, the hose 44 is wound so that the hose 44 is wound clockwise when viewed from the door opening 16.

  That is, the hose 44 connected to the hose connection port 46 is first wound in the direction of the hose storage portion 36 along the lower inner wall of the first housing 12-1 and is wound from the lower side of the hose storage space 36, and thereafter The nozzle attached to the lower bucket frame 40 is taken out clockwise from the hose guide 42 attached to the bucket frame 40 near the center of the hose. A nozzle 48 is detachably attached to the holder 50.

  By storing the hose connection port 46 at the lowermost position in such a hose storage space 36 and storing it in a right-handed manner, as shown in the conventional example of FIG. When the portion 112a is fed into the upper portion of the hose storage space, there is no hose portion (approximately half a turn around) to be removed from the hose storage space, so that the hose 44 can be shortened and the volume of the hose storage space 36 is reduced. The housing 12 can be thinned.

  Further, since the hose winding start portion is sent to the lower side of the hose storage space 36 by right-hand winding, there is no need for protection against sliding against the hose bucket by the conventional left-hand winding of FIG. 8, and the structure can be simplified. it can.

  Further, the nozzle 48 at the tip of the hose taken out after being stored in the hose storage space 36 as a right hand is detachably mounted on the nozzle holder 50 with the water discharge portion facing downward, and since the water discharge portion faces downward, the fire hydrant door is attached. The nozzle 48 can be opened with the water discharge part facing downward, and the water is not discharged unless the fire hydrant valve opening / closing lever 64 provided in the fire hydrant valve is operated. Since the water outlet is not suitable for the user, the nozzle 48 can be removed with a sense of security, which is a great safety advantage.

  FIG. 5 is a cross-sectional view of the valve housing space of FIG. 1 and simultaneously shows an embodiment of a fire hydrant valve opening / closing lever according to the present invention.

  In FIG. 5, the fire hydrant door 18 in the closed state on the front surface of the first housing 12-1 can be opened to the illustrated forward position around the hinge 21 by releasing the latch by a handle operation. In this case, the hydrant door 18 is reduced in weight because it is not provided with a nozzle or a hydrant valve opening / closing lever as in the prior art, and is provided with a damper mechanism 68 that absorbs an impact at the time of opening.

  In the valve storage space 38, a water supply valve 52, a fire hydrant valve 54, and a maintenance device 60 are arranged continuously in the vertical direction. An automatic drain valve (not shown) is mounted on the secondary side of the fire hydrant valve 54.

  A fire hydrant valve opening / closing lever 64 is directly attached to the fire hydrant valve 54. That is, the hydrant valve opening / closing lever 64 has a lever handle 65 attached in the lateral direction, and the hydrant valve opening / closing lever 64 is in the closed position in the upward position shown in the figure, and the hydrant valve 54 is closed. When the fire hydrant valve 54 is in a closed state, there is no fire extinguishing water in the pipe, and there is no pressure, so the automatic drain valve is in an open state.

  The lever handle 65 is rotatably provided on the fire hydrant valve opening / closing lever 64 around the center line of the handle. By rotating the handle 65, the fire hydrant valve opening / closing lever 64 can be easily moved up and down while holding the handle at the same position.

  When the fire hydrant valve opening / closing lever 64 is operated to the open position 64a that faces downward, the fire hydrant valve 54 is operated to the open position, the pressure rises in the pipe, and the automatic drain valve is operated to the closed position. Thus, the fire-extinguishing water pressurized from the water supply connection port 51 is regulated to a predetermined pressure through the automatic pressure regulating valve 56 and then supplied to the hose 44 side.

  At the same time, a switch installed behind the fire hydrant valve opening / closing lever 64 is turned on, whereby a signal is sent to the pump equipment and the pump equipment is started. When stopping the water discharge, returning the hydrant valve opening / closing lever 64 to the original upward position closes the hydrant valve 54 and simultaneously turns off the switch to stop the operation of the pump equipment.

  As described above, in the present embodiment, the fire hydrant valve opening / closing lever 64 that is conventionally provided on the fire hydrant door and opens and closes the fire hydrant valve by wire connection is disposed on the housing 12 side and provided directly on the fire hydrant valve 54. Thus, the structure of the fire hydrant door 18 is simplified, and a reduction in thickness and weight can be achieved.

  A stopper mechanism is provided for the fire hydrant valve opening / closing lever 64. The stopper mechanism holds the fire hydrant valve opening / closing lever 64 in the closed position when the fire hydrant door 18 is closed to prevent movement in the opening direction.

  In the present embodiment, the stopper mechanism has a door inner surface 72 of the fire hydrant door 18 in which the movement locus 72 of the lever tip that rotates the fire hydrant valve opening / closing lever 64 from the upper closed position to the lower open position is closed. It is arranged so as to be in a positional relationship passing outside and beyond. The positional relationship between the hydrant valve opening / closing lever 64 and the stopper mechanism in the closed position may be in constant contact and may not move in the opening direction, or the lever may move in the opening direction in a close positional relationship. You may make it regulate.

  With such an arrangement of the hydrant valve opening / closing lever 64 with respect to the hydrant door 18, the hydrant valve opening / closing lever 64 in the upwardly closed position shown in the figure is subjected to vibrations due to vehicle traffic, earthquakes, and the like, and the lower direction in the opening direction due to the weight of the lever. When trying to move to the side, the lever handle 65 at the tip of the lever comes into contact with the door inner surface 72 of the fire hydrant door 18 in the closed state, preventing movement of the lever in the opening direction and ensuring movement in the opening direction. Can be prevented.

  The fire hydrant door 18 can be closed only when the hydrant valve opening / closing lever 64 is in either the upward closed position or the downward opening position. When the hydrant valve opening / closing lever 64 is in the middle of opening / closing, the lever tip is The fire hydrant door 18 cannot be closed by hitting the lever. For this reason, the trouble that the fire hydrant door 18 is closed does not occur while the fire hydrant valve opening / closing lever 64 is in a halfway position in the middle of opening and closing.

  Furthermore, when the fire hydrant door 18 is opened, the stopper function of the fire hydrant valve opening / closing lever 64 is automatically released, and the lever can be operated, and the stopper release operation by the user is unnecessary and easy to operate.

  FIG. 6 is a sectional view showing another embodiment of a stopper mechanism for the fire hydrant valve opening / closing lever according to the present invention. In FIG. 6, the stopper mechanism is provided with a stopper member 74 that restricts the movement of the hydrant valve opening / closing lever 64 in the opening direction when the hydrant door 18 is closed.

  The stopper member 74 that protrudes from the inner surface of the door when the door is closed is positioned below the lever handle 65 provided on the fire hydrant valve opening / closing lever 64 in the closed position that is obliquely upward, and is subjected to vibrations due to vehicle traffic or earthquakes. When attempting to move downward in the opening direction due to the weight of the lever, the lever handle 65 at the tip of the lever comes into contact with the stopper member 74 protruding from the inner surface of the fire hydrant door 18 in the closed state, and in the opening direction. The movement of the lever can be prevented and the movement in the opening direction can be surely prevented. Other configurations are the same as those in the embodiment of FIG.
