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. 15 is a front view of a conventional fire hydrant device 100, FIG. 16 is a plan view of the internal structure of the fire hydrant device 100 with the fire hydrant door 104 open, and FIG. 17 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 apparatus 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 124 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 112 from being caught.

Further, a lever guard 118 is arranged beside the fire hydrant opening / closing lever 124 to prevent the hose 112 pulled out from the fire hydrant valve opening / closing lever 124 operated to the open position in front and coming back to the closed position.

An overhanging space with a width substantially equivalent to is secured. Of course, the overhanging amount of the overhanging hose guide 46 is better to project forward so as to be in a position where it does not hit when the fire hydrant door 18 is closed, and to have at least one hose width.

  A hose anti-slip member 66 such as a rubber bush is attached to the upper horizontal frame member provided in the hose bucket structure 40 to maintain the hose storage state in the hose storage space 36.

  FIG. 4 is a front view showing a state where the fire hydrant door 18 in the fire hydrant apparatus 10 of FIG. 1 is opened. When the handle 20 provided on the fire hydrant door 18 of FIG. 1 is pulled toward the front to release the lock, the fire hydrant door 18 opens to a position that is inclined downward. A fire hydrant valve opening / closing lever 64 is disposed inside the fire hydrant door 18. A nozzle 68 attached to the tip of the hose is detachably held in the holder 68 on the left side inside the fire hydrant door 18.

  FIG. 5 is a right side view showing the internal structure of FIG. 1 and shows the fire hydrant door 18 and the maintenance door 22 in an opened state. The fire hydrant door 18 is opened obliquely downward, and a fire hydrant valve opening / closing lever 64 for opening and closing the fire hydrant valve 54 by remote control is provided inside the door. The position of the fire hydrant valve opening / closing lever 64 is the closed position, and the position of the fire hydrant valve opening / closing lever 64a indicated by the front imaginary line is the open position.

  In addition, a projecting piece 70 is provided behind the fire hydrant door 18, and the projecting piece 70 abuts against a shock absorber 72 provided on the housing side, thereby holding an obliquely downward open position.

  The fire hydrant valve opening / closing lever 64 is pivotally supported at the lower end in the lever box 76 and has a handle 78 at the tip. A link wheel 80 that is rotated by the operation of the fire hydrant valve opening / closing lever 64 is provided in the lever box 76.

  FIG. 6 is an explanatory view showing a remote operation mechanism of the hydrant valve by the hydrant valve opening / closing lever. The link wheel 80 provided in the lever box 76 is connected to the link wheel 60 provided on the valve shaft of the fire hydrant valve 54 by two wire cables 82 and 84, and the wire cables 82 and 84 are connected to the lever box 76 and the holder 86. It is movably passed through wire tubes 88 and 90 having end portions fixed between them.

  When the fire hydrant valve opening / closing lever 64 is operated from the closed position shown in the drawing to the open position indicated by 64a by such a remote operation mechanism using the link wheels 60, 80 and the wire cables 82, 84, the link wheel 80 rotates integrally. Accordingly, the link wheel 60 rotates through the wire cables 82 and 84, and the fire hydrant valve 54 can be operated from the closed position to the open position.

  Here, the rotation amounts of the link wheels 60 and 80 are rotated by the same angle if the connecting radius of the wire is the same. Usually, the rotation angle for opening and closing the fire hydrant valve 56 is 90 °. In the present embodiment, the rotation angle for opening and closing the fire hydrant valve opening / closing lever 64 is about 180 °. In this case, remote operation with different rotation angles can be performed by reducing the wire connection radius of the link wheel 60 on the lever side and increasing the wire connection radius of the link wheel 80 on the fire hydrant valve 54 side.

  FIG. 7 is a side view showing the first embodiment of the fire hydrant valve opening / closing lever according to the present invention in the closed position and the opened position, and FIG. 8 shows a front view of the closed position and the opened position in the first embodiment. . 4 and 5 show the fire hydrant valve opening / closing lever of the first embodiment.

  7 (A) and 8 (A) show the closed position of the first embodiment, and the fire hydrant valve opening / closing lever 64 rotates relative to the lever box 76 arranged inside the fire hydrant door 18 opened obliquely downward. It is pivotally supported so that the internal link wheel 80 can be rotated. The fire hydrant valve opening / closing lever 64 is configured such that a handle 78 provided at the tip of the hydrant valve opening / closing lever 64 is positioned behind the hydrant door 18. The fire hydrant door 18 has a door recess 18a formed inside.

  FIGS. 7B and 8B show the open position of the first embodiment, and the opening operation of the fire hydrant valve opening / closing lever 64 is performed from the closed position of FIGS. 7A and 8A. Finally, the fire hydrant valve opening / closing lever 64 is substantially parallel to the inner surface of the door, and the handle 78 at the tip of the lever is substantially stored in the door recess inside the fire hydrant door 18. Operated to the open position.

  Moreover, the lever shape of the fire hydrant valve opening / closing lever 64 is a substantially trapezoidal shape bent downward as viewed from the side along the door recess 18a in the closed position in FIG. 7B. The whole is accommodated almost completely in the door recess 18 to minimize the amount of popping out and make it difficult for the hose to hit.

  In this way, when the handle 78 at the tip of the lever of the fire hydrant valve opening / closing lever 18 is housed in the door recess 18a inside the door and operated to the open position with the least amount of popping out, the hose with the nozzle is pulled out. In addition, even if the hose passes through the portion of the hydrant valve opening / closing lever 64 in the open position, it is possible to reliably prevent the hose from hitting the hydrant valve opening / closing lever 64 in the open position and returning to the closed position.

  Further, as a guard for the hydrant valve opening / closing lever 64, it is not necessary to provide the lever guard 124 as in the conventional example shown in FIG. 16, the structure of the hydrant door 18 is simplified, and the member does not protrude inside the door. Securing storage space on the housing side is not necessary, and there is no restriction on device arrangement on the housing side.

  When the hydrant valve opening / closing lever 64 is operated to the open position, a pump activation switch (not shown) is turned on, a pump activation signal is sent to the pump control panel, and the pump is operated to supply pressurized fire-extinguishing water.

  FIG. 9 is a side view showing the second embodiment of the fire hydrant valve opening / closing lever according to the present invention in the closed position and the open position, and FIG. 10 shows a front view of the closed position and the open position in the second embodiment. .

  9 (A) and 10 (A) show the closed position of the second embodiment, and the fire hydrant valve opening / closing lever 92 rotates relative to the lever box 76 arranged inside the fire hydrant door 18 opened obliquely downward. It is pivotally supported so that the internal link wheel 80 can be rotated. The fire hydrant valve opening / closing lever 92 is arranged such that a handle 78 provided at the tip of the hydrant valve opening / closing lever 92 is positioned behind the hydrant door 18.

  9 (B) and 10 (B) show the open position of the second embodiment, and the opening operation of the fire hydrant valve opening / closing lever 92 is performed from the closed position of FIGS. 9 (A) and 10 (A). 78 is turned to the front, and finally, the fire hydrant valve opening / closing lever 64 is substantially parallel to the inner surface of the door, and the handle 78 at the end of the lever is the outer position opposite to the front end of the fire hydrant door 18. To operate.

  The lever shape of the fire hydrant valve opening / closing lever 92 is a substantially trapezoidal shape bent downward as viewed from the side along the door recess 18a at the closed position in FIG. 10B. Thus, the entire lever is accommodated almost completely in the door recess 18 so that the amount of protrusion is kept to a minimum and minimum source so that the hose is more difficult to hit.

  Thus, by operating the fire hydrant valve opening / closing lever 18 to the open position where the handle 78 portion at the end of the lever exceeds the door end and becomes the outside relative position, when the hose with the nozzle is pulled out, the open position is set. Even if a hose passes through a portion of a certain hydrant valve opening / closing lever 64, it is possible to reliably prevent the hose from hitting the hydrant valve opening / closing lever 64 in the open position and returning to the closed position.

  In addition, since the structure of the fire hydrant door 18 is simplified and members do not pop out inside the door, it is not necessary to secure a storage space on the housing side, and there is no restriction on device arrangement on the housing side.

  Further, in the second embodiment of FIGS. 9 and 10, the length of the fire hydrant valve opening / closing lever 92 is longer than that of the first embodiment shown in FIGS. 7 and 8, and accordingly, the operation force is reduced accordingly. Can be opened and closed lightly. The fire hydrant valve opening / closing lever 64 protrudes outward from the fire hydrant door 18, so that the fire hydrant door opening / closing lever 64 cannot be closed to the housing side when the fire hydrant opening / closing lever 64 remains open. It is possible to prevent forgetting to return and forgetting to set to the closed position during construction.

  Further, as shown in FIG. 10, a single hydrant valve opening / closing lever 92 is attached with a handle 78 so as to be L-shaped at the tip. However, as in the first embodiment of FIG. Alternatively, the lever may be taken out from the lever and a handle 78 may be provided at the tip.

  FIG. 11 is a side view showing the third embodiment of the fire hydrant valve opening / closing lever according to the present invention in the closed position and the open position, and FIG. 12 shows a front view of the closed position and the open position in the third embodiment. .

  FIGS. 11A and 12A show the closed position of the third embodiment. A plate-shaped fire hydrant valve opening / closing lever 94 with respect to the lever box 76 disposed inside the fire hydrant door 18 opened obliquely downward. Is pivotally supported so that the internal link wheel 80 can be rotated. The fire hydrant opening / closing lever 92 is in a closed position so that a handle 78 provided in an L shape at the tip is positioned behind the hydrant door 18.

  As is apparent from FIG. 12A, a lever passage groove 95 is formed at the tip of the fire hydrant door 18 along the turning direction of the fire hydrant opening / closing lever 94.

  11 (B) and 12 (B) show the open position of the third embodiment, and the opening operation of the fire hydrant valve opening / closing lever 94 is performed from the closed position of FIGS. 11 (A) and 12 (A). The lever 78 is turned to the front, and the lever part passes through the lever through groove 95 opened on the distal end side of the fire hydrant door 18, and the handle 78 at the distal end of the lever becomes the lower side of the fire hydrant door 18. Operate to the open position.

  When the handle 78 at the end of the lever of the fire hydrant valve opening / closing lever 94 passes through the lever passage groove 95 of the fire hydrant door 18 and is operated to the open position below the door, the hose with the nozzle is pulled out. In addition, even if the hose passes through the portion of the fire hydrant valve opening / closing lever 64 in the open position, the hose does not hit the fire hydrant valve opening / closing lever 64 in the open position, and it is ensured that it returns to the closed position by the contact of the hose. Can be prevented.

  In addition, since the structure of the fire hydrant door 18 is simplified and members do not pop out inside the door, it is not necessary to secure a storage space on the housing side, and there is no restriction on device arrangement on the housing side. When the hydrant door 18 is closed at the open position of the hydrant valve opening / closing lever 95, the hydrant valve opening / closing lever 95 is conspicuously exposed from the surface of the hydrant device, so that the hydrant valve opening / closing lever 95 is forgotten to be returned to the closed position during construction. Forgetting to set can be prevented.

  FIG. 13 is a side view showing a fourth embodiment of the fire hydrant valve opening / closing lever according to the present invention with respect to the closed position and the open position, and FIG. 14 is a front view of the inside of the fire hydrant door with respect to the closed position and the open position of the fourth embodiment.

Is pivotally supported to rotate the internal link wheel 80, and a handle 78 is provided at the tip.

  In the fourth embodiment, the position where the hydrant valve opening / closing lever 96 is rotated in front of the hydrant door 18 is an open position, and the position where the hydrant door 18 is rotated rearward is an open position. The positional relationship is the reverse of that in the first to third embodiments in FIG.

  The lever box 76 forms a stepped-down portion 76a for positioning the fire hydrant valve opening / closing lever 96 substantially parallel to the inner surface of the door when the lever box 76 is in the open position on the rear side of the door, and the position facing the tip of the handle 78 when the stepped-down portion 76 is closed. A guard block 98 is disposed on the side.

  The guard block 98 is a columnar body whose end face is a right triangle, and is arranged such that a vertical plane is opposed to the lever tip and an inclined plane is positioned on the opposite side.

  FIGS. 13 (B) and 14 (B) show the open position of the fourth embodiment. The opening operation of the fire hydrant valve opening / closing lever 96 is performed by closing the front door of FIGS. 13 (A) and 14 (A). From the position, the handle 78 is turned so as to be pushed in the depth direction so that the handle 78 at the end of the lever is parallel to the stepped portion 76a of the lever box 76 so that the end of the handle fits in the guard block 98. Operate to the open position.

  In this way, when the handle 78 at the tip of the lever of the fire hydrant valve opening / closing lever 98 is operated to the open position where it falls within the cover range of the guard block 98, when the hose with the nozzle is pulled out, the handle 78 Even if the hose tries to hit the tip, it will ride on the lever side over the handle tip due to the inclined surface of the gart block 98, and even if the hose passes through the portion of the fire hydrant valve opening / closing lever 64 in the open position, It can be reliably prevented from returning to the closed position.

  Further, the guard block 98 only needs to have a height exceeding the handle 78 which is substantially horizontal with the inner surface of the door in the open position, and the amount of protrusion to the inner side of the door is very small, so that the structure of the fire hydrant door 18 can be simplified. Since the member hardly protrudes inside the door, it is not necessary to secure a storage space on the housing side, and there is no restriction on device arrangement on the housing side.

  In addition, as shown in FIG. 13, the opening operation is performed by pushing the hydrant valve opening / closing lever 96 from the front to the back with the hydrant door 18 opened obliquely downward, but the hydrant valve opening / closing lever 96 is pushed by pulling it forward. It is easier to operate and high operability is obtained. In order to prevent an operator's finger from being caught between the lowering part 76a and being injured when the hydrant valve opening / closing lever 96 is in the closed position, a space for inserting a finger between the hydrant opening / closing lever 96 and the lowering part 76a is provided. The stepped-down portion 76a may be further lowered so as to be provided.

  In the above embodiment, the fire hydrant door is opened obliquely downward and the hydrant valve opening / closing lever inside the door is operated. However, as in the conventional example shown in FIGS. The present invention can be applied to a fire hydrant device having a structure opened to a position.

  As shown in FIG. 4, the nozzle 45 is mounted on the holder inside the fire hydrant door 18, but a holder is provided on the right plate portion of the hose bucket structure 40, and the nozzle 45 is disposed sideways here. May be.

  Further, in the embodiment of FIG. 5, when the fire hydrant door 18 is closed when the lever is in the open position 64a in order to prevent forgetting to return the fire hydrant valve opening / closing lever 64 to the closed position at the end of fire extinguishing or construction, A protrusion member or the like that prevents the fire hydrant door 18 from closing due to the member provided on the housing side colliding with the fire hydrant valve opening / closing lever 78 may be provided on the housing side.

  In the above embodiment, the case is divided into the fire hydrant side and the fire extinguisher side, but the hose outlet of the above embodiment is similarly applied to the integrated housing structure. It is possible to apply a hose bucket structure in which is disposed in the approximate center of the door opening.

  Further, the hose storage space 36 and the valve storage space 38 may be arranged in reverse.

Further, the present invention includes appropriate modifications that do not impair the object and advantages thereof, and is not limited by the numerical values shown in the above embodiments.
