Description

The present invention relates to a fire hydrant device that opens a fire hydrant door and pulls 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. 9 is a front view of a conventional fire hydrant device 100, FIG. 10 is a plan view of the internal structure of the fire hydrant device 100 with the fire hydrant door 104 open, and FIG. 11 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.

  A frame pipe 115 formed in a U shape is arranged on the opening side as a hose bucket structure in the hose storage portion of the housing 102. A hose bucket 116 is attached to both sides of the frame pipe 115, a hose storage space is formed inside, and a hose 112 with a nozzle 110 attached to the tip is housed inside the 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.

  Such a fire hydrant device 100 opens a fire hydrant door 104, pulls out a hose 112 with a nozzle 110, and operates a fire hydrant valve opening / closing lever 114 provided in the door when a vehicle accident involving a fire occurs. At the same time, a pump start switch (not shown) is turned on at the lever open position, and the fire-extinguishing pump equipment can be started to discharge water.

  Further, a hose guide 122 using an inverted U-shaped pipe frame or the like is provided inside the fire hydrant door 104, and the hose 114 is pulled out through the hose guide 122 to prevent the hose 114 from being caught.

  Further, a lever guard 118 is arranged beside the fire hydrant opening / closing lever 114 to prevent the hose 112 pulled out to the fire hydrant valve opening / closing lever 114 operated to the front open position and returning to the closed position.

  FIG. 12 shows a remote opening / closing mechanism of the hydrant valve 120 by the hydrant opening / closing lever 114. A pulley 124 is attached to the valve shaft of the fire hydrant valve 120, and the fire hydrant opening / closing lever 114 can rotate the pulley 126. After fixing one end of the wire 128 to the pulley 126, it is wound around the pulley 124 and fixed to the fixing portion. It fixes with 126, and it returns to the pulley 126 again and the other end is fixed.

For this reason, when the hydrant valve opening / closing lever 114 in the illustrated closed position is rotated so as to be pulled forward, the wire 124 is released and the pulley 124 is also rotated, and the hydrant valve 120 is opened. Further, the hydrant valve 120 can be closed by returning the opened hydrant valve opening / closing lever 114 to its original position.

  However, in such a conventional tunnel fire hydrant device, the hose guide 122 is provided inside the fire hydrant door, and the lever guard 116 is disposed beside the fire hydrant valve opening / closing lever 114, and the hose 112 is moved to the right side. Although the hose 112 is prevented from hitting the lever when it is pulled out, the lever guard 118 must be lower than the handle portion so that the lever can be operated. Since the handle portion of the lever protrudes beyond this point, the hose 112 may hit that portion and return to the closed position.

  In addition, since the lever guard 118 is disposed inside the fire hydrant door 104 for smooth drawing of the hose, the structure of the fire hydrant door 104 is complicated. Furthermore, when the fire hydrant door 104 is closed, it is necessary to secure a space on the housing 102 side so that the lever guard 118 protruding inward can be housed in the housing 102. There is also a problem that the arrangement of is restricted.

An object of this invention is to provide the fire hydrant apparatus provided with the structure which prevents reliably that the hose pulled out hits a remote control part and a fire hydrant valve returns to a closed position.

The present invention provides a fire hydrant valve opening / closing lever that remotely opens and closes a fire hydrant valve arranged in the housing inside a fire hydrant door that is detachably attached to the door opening on the front surface of the housing, and opens the fire hydrant door with a nozzle. In a fire hydrant device that pulls out a hose and discharges water,
The fire hydrant valve opening / closing lever is provided so as to be rotatable around a horizontal position between a front open position and a rear closed position in a plane substantially parallel to the inner surface of the door.

  Here, the fire hydrant valve opening / closing lever is supported by a shaft portion disposed in the operation box or the cover so as to be rotatable around the horizontal, and the height of the fire hydrant valve opening / closing lever in the horizontal direction exceeds the height of the operation box or the cover. Place it in a position that is not.

The fire hydrant valve opening / closing lever is arranged on the inner surface of the door so that a part of the fire hydrant valve opening / closing lever is located at the periphery or outside of the periphery of the fire hydrant door when operated to the forward open position.

  According to the present invention, the fire hydrant valve opening / closing lever for remotely opening and closing the fire hydrant valve by rotating around the horizontal parallel to the inner surface of the door is provided on the inner side of the opened fire hydrant door. Compared to rotating around, the amount of protrusion on the inner surface of the door can be greatly reduced, and even if the hose pulled out from the housing hits the fire hydrant valve opening lever part, the fire hydrant valve opening / closing lever is horizontal. A movement that rotates around and returns to the closed position does not occur, and the fire hydrant valve that is remotely operated by hitting the hose can be reliably prevented from returning to the closed position.

  The hydrant valve opening / closing lever is supported so as to be rotatable around the horizontal by a shaft portion arranged in the operation box or cover, and the height of the hydrant valve opening / closing lever does not exceed the height of the operation box or cover. As a result, the hose hits the operation box or cover, but it is difficult to hit the fire hydrant valve opening / closing lever in a lower position, and the fire hydrant valve remotely operated by the hose hits will return to the closed position. Can be reliably prevented.

Even if the fire hydrant valve opening operation part is arranged inside the fire hydrant door, the fire hydrant valve opening / closing lever is rotated around the horizontal parallel to the inner surface of the door, so the height including the operation box and cover can be kept low. In addition, since the structure of the fire hydrant door is simplified and there is almost no protrusion to the housing side, the space on the housing side for closing the fire hydrant door can be eliminated.
