Description

[Technical Field]

[0001] The present invention relates to a fire hydrant device that pulls out a nozzle-equipped hose to discharge fire-fighting water or fire-fighting foam. [Background technology]

[0002] Conventionally, fire hydrant devices have been installed as emergency equipment inside tunnels on expressways and expressways, and the fire hydrant device has a fire hydrant door that can be opened freely and houses a hose with a nozzle attached to the end and valves including a fire hydrant valve.

[0003] Fire hydrant devices are generally installed embedded in the tunnel walls along the tunnel side walls, for example at intervals of 50 meters. In the event of a vehicle accident involving a fire, in tunnels with guard passages, road users such as the driver of the accident vehicle climb up to the guard passage using steps installed on the side of the guard passage, open the hydrant door of the fire hydrant device installed on the tunnel wall to the front, take out the hose with the nozzle, and carry out firefighting work.

[0004] The inspector's passage is a side wall passageway that is elevated above the road surface, allowing inspectors to safely inspect various equipment installed inside the tunnel, including fire hydrant devices, without interfering with vehicle traffic inside the tunnel.

[0005] In addition, in tunnels without guard passages, users such as the driver of the accident vehicle must Approach the fire hydrant installed on the wall of the building and, in the same way, open the fire hydrant door forward and insert the nozzle. The hose is then taken out to carry out firefighting work. [Prior art documents] [Patent documents]

[0007] By the way, in urban tunnels constructed by shield construction, etc., The structure does not allow for the installation of a fire hydrant device buried in the wall on the side of the guard passage. It is necessary to install it internally.

[0008] However, a fire hydrant device with a front-opening door like a conventional fire hydrant is installed in the guard passage. In this case, when the fire hydrant door is opened, it may exceed the building limit and jump out onto the road.

[0009] On the other hand, even if this problem could be solved, it would be necessary to install the fire hydrant equipment at the guard station facing the road inside the tunnel. If the hydrant is installed along the wall of the passageway, a vehicle fire may occur and the vehicle may stop in front of the hydrant door. In such a case, a stopped vehicle may get in the way and prevent you from opening the fire hydrant door and pulling out the hose. Furthermore, even if it is possible to operate the fire hydrant door from the guard's passage, In order to operate the fire hydrant, you need to bend down and reach out, which can make it difficult to operate. be.

[0016] [Outline of tunnel emergency equipment] Figure 1 is an explanatory diagram showing emergency tunnel equipment, including fire hydrant equipment, installed in a tunnel for expressways. As shown in Figure 1, the inside of a tunnel 10 constructed using the shield tunneling method is covered with cylindrical tunnel walls 12, and roads 15 are provided by being separated by deck slabs 18. In this example, road 15 has two lanes in each direction.

[0017] A guard passage 14 is provided along the tunnel wall 12 on the left side of the road 15 separated by the deck 18, and the internal space below the guard passage 14 is used as a duct 22 in which electrical conduits and the like are laid. The guard passage 14 is, for example, 90 centimeters high and 70 centimeters wide.

[0018] The underside of the deck 18 on which the road 15 is formed is divided into multiple sections laterally across the tunnel, and for example, the section located below the guard passage 14 is used as a maintenance passage 20, which is also used as an emergency evacuation passage in the event of a fire inside the tunnel. A water supply main 24 is laid in the maintenance passage 20.

[0019] Fire hydrant equipment 16 is installed every 50 meters along the length of tunnel 10, and each fire hydrant equipment 16 is installed separately into a fire hydrant storage box 30 containing the hose and a water discharge control mechanism storage section 26.

[0020] The fire hydrant storage box 30 is placed in a hydrant embedded section that is hollowed out in a box shape from the road surface of the guard passage 14 to the wall on the road 15 side. The water discharge control mechanism storage section 26 is placed in the management passage 20 below the fire hydrant storage box 30, and a branch pipe branching off from the main water supply pipe 24 is drawn in, and a water supply pipe 25 that supplies fire water to the fire hydrant storage box 30 is also erected.

[0021] [Fire hydrant facilities] FIG. 2 is an explanatory diagram showing the appearance of a fire hydrant storage box under normal conditions, FIG. 3 is an explanatory diagram showing the appearance of the fire hydrant storage box of FIG. 2 from the front and from above, and FIG. 4 is an explanatory diagram showing the appearance of the fire hydrant storage box of FIG. 2 from the side.

[0022] (External structure of fire hydrant storage box) 2 to 4, the hydrant storage box 30 of the fire hydrant equipment 16 is installed by embedding it in the internal space below the road surface of the monitor passage 14. The fire hydrant storage box 30 has a front door 32 arranged in a front door opening 33 formed on the upper center of the front surface of the housing 31 so that the front door 32 can slide freely up and down.

[0023] A first upper door 34 having the same width as the front door 32 is disposed in a first upper door opening 35 formed in the center of the top surface of the fire hydrant storage box 30 on the road side of the monitor passage 14. Furthermore, a second upper door opening 37 is formed in the center of the front side of the first upper door 34, and a second upper door 36 is disposed in this opening.

[0024] The first upper door 34 is supported on both sides of the front edge of the door by hinges 46 located at the front corners of the upper part of the housing 31, and can be opened upward from the rear around the hinges 46, as shown in Figure 4.

[0025] The rear edge of the second upper door 36 is pivotally supported by a hinge 42 on the second upper door opening 37 of the first upper door 34, and as shown in Figure 4, the second upper door 36a can be opened upward around the hinge 42 so as to open forward.

[0026] A front-opening handle 38 is journalled by a hinge 44 on the front edge of the second upper door 36, and a front-opening mechanism provided on the handle body of the front-opening handle 38 keeps the front door 32 locked in the closed position as shown when the second upper door 36 is closed. When a user operates the door from the road 15 side, opening the front-opening handle 38 releases the front door 32 from being locked to the second upper door 36, and the front door 32 falls to the back side of the housing 31 under its own weight, opening the front door opening 33. Also, by opening the second upper door 36 from the front, the second top door opening 37 of the fire hydrant storage box 30 is opened.

[0027] Here, the hinge 46 that pivots the first upper door 34 to the front edge corner of the housing 31 and the hinge 44 that pivots the front-opening handle 38 to the front edge of the second upper door 36 are arranged so that their axis lines are coaxial, and the front-opening handle 38, which locks the housing 31 and front door 32 in the closed position, is the fixed side, and the hinges 44, 46 pivotally support the first upper door 34 together with the second upper door 36 so that they can be freely opened rearward.

[0028] A reporting device panel 48 is provided on the upper left front of the fire hydrant storage box 30. The reporting device panel 48 is equipped with a red indicator light 50, a transmitter 52, a response lamp 54, and a telephone jack 55. The red indicator light 50 is always lit, allowing the location of the fire hydrant equipment to be identified from a distance. In the event of a fire, when the transmitter 52 is pressed to turn on the push-button switch, a transmission signal is sent to a disaster prevention receiving panel installed in a monitoring room or monitoring center, etc., and a fire alarm is issued. In response, a response signal is sent from the disaster prevention receiving panel, which lights up the response lamp 54 and causes the red indicator light 50 to flash.

[0029] [Front opening mechanism] Fig. 5 is an explanatory diagram showing the front opening handle portion of a fire hydrant storage box equipped with a front opening mechanism, Fig. 5(A) shows the front, and Fig. 5(B) shows the side as seen from XX in Fig. 5(A). Fig. 6 is an explanatory diagram showing the mechanical structure of the front opening mechanism that opens the second upper door from the front and slides open by dropping the front door, Fig. 6(A) shows the closed state, and Fig. 6(B) shows the state when the front opening handle is opened.

[0030] As shown in Figure 5, shaft members 56 of the front-opening mechanism are protruded from both sides of the handle body 38a of the front-opening handle 38, which is supported by hinges 44 on the tip of the second upper door 36 located on the top surface of the hydrant storage box 30.When the second upper door 36 is in the closed state, the tip of the shaft member 56 is inserted into the shaft hole of a bearing member 58 located on the back side of the front door 32, thereby engaging the front door 32 with the second upper door 36 and holding it in the closed position.

[0031] When the front opening handle 38 is lifted up, the shaft member 56 is pulled inward and comes out of the shaft hole of the bearing member 58, thereby releasing the lock on the front door 32, and the front door 32 slides down under its own weight, opening the front door opening 33.

[0032] As shown in Figure 6(A), the front-opening mechanism 60 has one end of a pair of bent links 62 connected by a moving fulcrum 64 inside the handle main body 38a, the bent position of the link 62 being fixed to the handle main body 38a side as a rotation fulcrum 66, and the other end of the link 62 being connected to a fulcrum 68 at the shaft end of the shaft member 56 as a sliding fulcrum 70, and further the moving fulcrum 64 is urged upward as shown by a spring 72.

[0033] When the front-opening handle 38 is not operated, the link 62 rotates outward under the force of the spring 72, fitting the shaft member 56 into the shaft hole 58a of the bearing member 58 and locking the front door 32 to the second upper door 36.

[0034] When the front-opening handle 38 is lifted up, as shown in Figure 6 (B), the moving fulcrum 64 moves downward against the spring 72 via a link mechanism not shown, causing the link 62 to rotate inward and pull the shaft member 56 inward, thereby removing the tip of the shaft member 56 from the shaft hole 58a of the bearing member 58, releasing the lock on the front door 32, causing the front door 32 to slide down under its own weight and open the front door opening 33.

[0035] The front-opening mechanism 60 is not limited to the link mechanism of FIG. 6, but may include any suitable link mechanism that pulls the shaft member 56 inward by lifting up the front-opening handle 38 and removes it from the shaft hole 58a of the bearing member 58.

[0036] [Internal structure of a fire hydrant storage box] FIG. 7 is an explanatory diagram showing the internal structure of a fire hydrant storage box, where FIG. 7(A) shows the front view and FIG. 7(B) shows a plan view seen from the YY cross section of FIG. 7(A).

[0037] As shown in FIG. 7, the lower interior side of the housing 31 of the fire hydrant storage box 30 serves as a hose storage section 74, in which a shape-retaining hose 76 is wound inward in a horizontal overlapping manner.

[0038] The rectangular shape of the housing 31 when viewed from above is approximately 1.4 meters wide and approximately 0.35 meters deep, and therefore, when the hose 76 is wound inward in the hose storage section 74, the wound shape of the hose 76 becomes a rounded rectangle consisting of two parallel lines and two semicircles, and the length of one turn of the hose 76 wound inward inside the flat rectangular housing 31 is approximately 3.5 meters. As the hose length needs to be 30 meters or more, the hose 76 should be wound inward with nine or more overlapping turns.

[0039] Here, the hose 76 wound inward in the shape of a rounded rectangle within the housing 31 is shown as parallel line hose portions 76a and 76c and semicircular hose portions 76b and 76d.

[0040] A hose guide structure 80 is provided on the central front side of the housing 31 to deform inward the parallel wire hose portion 76a on the front side of the hose 76 wound inward in a rounded rectangle inside the housing 31.

[0041] The hose guide structure 80 has four guide pipes 80a, 80b, 80c, and 80d made of metal that stand upright on a bottom plate 81, with the guide pipes 80a and 80d at both ends standing along the inner surface of the housing 31 and the central guide pipes 80b and 80c standing up a predetermined length inward, and by winding the hose 76 inward along the guide pipes 80a, 80b, 80c, and 80d of the hose guide structure 80, the parallel hose portion 76a on the front side of the hose 76 is deformed inward and takes on a shape roughly resembling a gourd, and this deformation generates a repulsive force in the deformed parallel hose portion 76a of the hose 76 that causes it to spread outward.

[0042] By providing such a hose guide structure 80, the hose 76, which is overlapped and wound inward inside the housing 31, generates a repulsive force that tries to spread outward as the rounded oval parallel hose portion 76a is deformed inward by the hose guide structure 80, and a force pressing it against the inner wall of the housing 31 is generated, making it possible to reliably prevent the parallel hose portions 76a, 76c of the overlapped and wound inward hose 76 from collapsing inward even if they become long.

[0043] Here, the hose guide structure 80 deforms the parallel hose portion 76a on the front side of the hose 76 inward, but does not deform the parallel hose portion 76c on the back side inward. However, due to the inward deformation of the parallel hose portion 76a, the force that tends to spread outward as a whole of the hose 76 increases, and it becomes possible to reliably prevent the parallel hose portion 76c on the back side, which has not been deformed inward, from collapsing inward.

[0044] Furthermore, when the front door 32 and the second upper door 36 or the first upper door 34 are opened to pull the hose 76 outward, in addition to the force that tries to push the hose out due to the deformation of the radial hose portions 76b, 76d of the hose 76, a force that tries to push the hose out is also generated in the parallel hose portion 76a of the hose 76 due to the inward deformation caused by the hose guide structure 80, thereby reducing the force required to pull out the hose 76.

[0045] Guide pipes 82a to 82c and guide pipes 84a and 84b are arranged in the upper part of the hose guide structure 80 so as to surround the inside of the front door opening 33, the first top door opening 35, and the second top door opening 37 shown in FIGS. 1 and 2. When the hose 76 is drawn out to the outside, the guide pipes 82a to 82c are guided by the guide pipes 82a to 82c. c Alternatively, by slidingly contacting the guide pipes 84a and 84b, wear on the hose 76 is prevented and the force required to pull out the hose is reduced.

[0046] Additionally, a foam nozzle 78 connected to the tip of the hose 76 is detachably attached to the back surface of the second upper door 36 by a nozzle holder 86. In this embodiment, the nozzle holder 86 attaches the foam nozzle 78 by suspending it from a pivotal support on the back surface of the second upper door 36, and even when the second upper door 36 is opened from the front as shown in second upper door 36a in Figure 4, or when the first upper door 34 is opened from the rear together with the second upper door 36 as shown in first upper door 34a in Figure 4, the nozzle holder 86 attaches the foam nozzle 78 to the back surface of the second upper door 36 in a suspended state.

[0047] Therefore, when the second upper door 36 is opened from the front or the first upper door 34 is opened from the rear together with the second upper door 36, the foam nozzle 78 suspended from the back of the door will appear at the top of the fire hydrant storage box 30.

[0048] When the second upper door 36 is opened, the foam nozzle 78 held on the back of the door appears at a position within a range of approximately 0.9 to 1.3 meters from the road surface 15, which corresponds to the range from the waist to the shoulders of a user standing on the road surface 15.Since the foam nozzle 78 appears right in front of the user, it can be easily removed.

[0049] In addition, when the first upper door 34 is opened from the rear, the position at which the foam nozzle 78 held on the back of the door appears is somewhere in the range of approximately 0.2 to 0.4 meters from the road surface of the monitor passage 14, so that the foam nozzle 78 appears right in front of the user who is bending over the monitor passage 14 and operating the rear-opening handle 40, and the user can easily remove the foam nozzle 78 from the monitor passage 14 side.

[0050] In addition to the hanging type, nozzle holder 86 may also be a split ring-shaped nozzle holder that is fixed to the rear surface of the door and opens to the removal side to detachably engage foam nozzle 78.

[0051] Furthermore, an operation box is disposed inside the right side of the top opening of housing 31, and a fire hydrant valve opening / closing lever is provided on the operation box to open and close a manual pilot valve provided inside the operation box (not shown). When the fire hydrant valve opening / closing lever is operated to open, the manual pilot valve is opened, and the fire hydrant valve disposed separately in water discharge control mechanism storage section 26 shown in Figure 1 can be remotely opened.

[0052] Furthermore, one or more of the operation box, manual pilot valve, and hydrant opening / closing lever may be placed in the free space secured by the hose guide structure 80. Also, the connecting member between the manual pilot valve and the hydrant opening / closing lever, and part of the piping from the manual pilot valve to the hydrant valve may be placed in the free space.

[0053] By arranging appropriate components in the empty space as described above, it is possible to effectively utilize the space of the fire hydrant storage box that is placed in the watchman's passageway, where space is limited.

[0054] [Opening the second upper door and front door from the road side] FIG. 8 is an explanatory diagram showing the opening operation of the front door and the second upper door when operated from the road side.

[0055] As shown in Figure 8, when a user operates the fire hydrant storage box 30 from the road side, by lifting up the front opening handle 38, the front door 32 is released from its lock, and the front door 32 slides down under its own weight, opening the front door opening 33.

[0056] Next, when the user performs the front-opening operation to open the second upper door 36 in the depth direction, as shown in Figures 6(A) and (B), the shaft members 56 arranged on both sides of the handle main body 38a are pulled out from the bearing members 58 on the back surface of the front door 32, the second upper door 36 is opened forward around the hinge 42, and the second top door opening 37 is opened.

[0057] At this time, as shown in Figure 7(A), the nozzle holder 86 located on the back side of the second upper door 36 is positioned in front of the user on the road, and the foam nozzle 78 engaged with the nozzle holder 86 appears in front of the user, allowing the user to easily remove the foam nozzle 78 and pull out the hose 76.

[0058] [Opening the upper door from the guard passage] FIG. 9 is an explanatory diagram showing the opening operation of the first upper door when operated from the guard passage side.

[0059] As shown in Figure 9, when a user operates the fire hydrant storage box 30 from the guard passage side, the user bends down from the guard passage and lifts up the rear-opening handle 40, which releases the lock on the rear edge side of the first upper door 34 to the housing 31 side, and the first upper door 34 opens rearward around the hinge 46 at the front edge corner, opening the first top door opening 35.

[0060] At this time, the second upper door 36 is also opened to the rear together with the first upper door 34, centered around the hinge 44, and the front-opening handle 38 supported by the hinge 44 does not move, and the tip of the shaft member 56 of the front-opening mechanism 60 shown in Figure 6, which is provided on the front-opening handle 38, remains fitted in the shaft hole 58a of the bearing member 58 arranged on the back surface of the front door 32, and the second upper door 36 is opened to the rear together with the first upper door 34, while maintaining the front door 32 locked in the closed position.

[0061] When the first upper door 34 is opened from the rear to open the first top door opening 35, as shown in Figure 6(A), the foam nozzle 78 engaged with the nozzle holder 86 located on the back side of the second upper door 36 appears in front of the user bending over in the guard passage, allowing the user to easily remove the foam nozzle 78 and pull out the hose 76.

[0062] [Modifications of the present invention] (Front opening mechanism) The front-opening mechanism of the second upper door shown in the above embodiment is one example, and any appropriate mechanism is included as long as it has the function of locking the top of the front door to hold it in the closed position when the second upper door is in the closed position together with the first upper door, and when the front-opening handle is operated, unlocking the front door causes it to slide down and open the front door opening, and also allowing the door opening formed in the first upper door to be opened by operating the front-opening of the second upper door.

[0063] (Foam fire hydrant equipment) The above embodiment has been described with reference to a foam fire hydrant system that discharges fire-extinguishing foam, but the present invention is not limited to this and may be a fire hydrant system that discharges fire-extinguishing water.

[0064] (others) Although the above embodiment does not mention sending a signal when the door is opened, a signal may be sent when the door is opened. When the door is opened, it is assumed that a fire has occurred, and if there is no fire, it is assumed that the fire hydrant door has been opened due to vandalism or other reasons. In either case, a response is required. It is preferable that the signal be sent to a disaster prevention receiving panel that manages fire signals and fire hydrants, but the signal may be sent to any appropriate device. Different signals may be sent when the first top door and the second top door are opened.

[0065] The above embodiment takes a tunnel fire hydrant facility as an example, but is not limited to this. The fire hydrant storage box of the present invention can be applied to surfaces of different heights that people can walk on, such as two passage surfaces of different heights, or the top and bottom of a platform in a gymnasium or stage, and the wall surface adjacent to each surface.
