[Roof structure with roof door]
FIG. 11 is an explanatory view showing an embodiment of a roof structure provided with a roof door, FIG. 11 (A) shows a normal state, and FIG. 11 (B) shows an operating state when hydrogen gas leaks. .

  As shown in FIG. 11A, the hydrogen-side roof 18 of the hydrogen gas dispenser 14 has ventilation openings 70 on both sides of the support 54, and the roof door 68 can be rotated around the ventilation opening 70 by a shaft 69. The shaft 69 is driven to open and close the roof door 68 by a drive motor (not shown), and is held in a horizontal position for closing the ventilation opening 70 in a normal state. The motor that opens and closes the roof door 68 has an explosion-proof structure.

  When a flame due to a fire is detected by the flame detector 36 using the control panel 35 shown in FIG. 8, the hydrogen detector 38 uses a predetermined threshold concentration (for example, lower explosion limit 1) corresponding to the ignition concentration 4%. / 4), when the temperature detected by the temperature detector 40 exceeds a predetermined threshold temperature, when a start signal is received by operating the starter 42, or when a fire is received from the fire receiving panel 32 When a transfer signal is received or when acceptance of the opening operation of the roof door operation switch provided in the operation unit 104 is detected, as shown in FIG. 11B, the roof door is rotated by the rotation of the shaft 69 by the drive motor. The ventilation port 70 is opened by rotating 68 to a vertical position.

  For this reason, the leaked hydrogen gas diffuses upward through the ventilation opening 70 opened by the roof door 68, and it is possible to prevent the hydrogen gas from entering the refueling facility area A1 and becoming a fire factor that leads to a large-scale fire. To do.

  Further, the control panel 35 may perform a control to open the roof door 68 in a fine weather or cloudy weather and to close the roof door 68 in a rainy weather by a predetermined operation.

The leaked hydrogen gas can be diffused by ventilating upward through a vent opening with the roof door open.

[Modification of roof structure with roof door]
FIG. 12 is an explanatory view showing an embodiment of a roof structure provided with a roof door, FIG. 12 (A) shows a normal state, and FIG. 12 (B) shows an operating state when hydrogen gas leaks. FIG. 12C shows a normal state seen from the boundary side, and FIG. 12D shows an operating state seen from the boundary side.

As shown in FIGS. 12A and 12C, the hydrogen side roof 18 of the hydrogen gas dispenser 14 is rotated by a shaft 74 provided at the roof end on the left side of the support 54 facing the oil supply side roof 16. A roof door 72 is provided freely, and in a normal state, the roof door 72 is held in a horizontal state by a latch portion 75 operated by an electromagnetic solenoid. The electromagnetic solenoid of the latch part 75 has an explosion-proof structure.

When a flame due to a fire is detected by the flame detector 36 using the control panel 35 shown in FIG. 8, the hydrogen detector 38 uses a predetermined threshold concentration (for example, lower explosion limit 1) corresponding to the ignition concentration 4%. / 4), when the temperature detected by the temperature detector 40 exceeds a predetermined threshold temperature, when a start signal is received by operating the starter 42, or when a fire is received from the fire receiving panel 32 When a transfer signal is received or when acceptance of the opening operation of the roof door operation switch provided in the operation unit 104 is detected, energization of the electromagnetic solenoid is performed as shown in FIGS. 12 (B) and 12 (D). The operation of the latch portion 75 releases the holding of the roof door 72, whereby the roof door 72 rotates downward about the shaft 74 due to its own weight, and hangs downward from the roof end to form a partition wall. Large ventilation opening 73 is opened in the roof lid 72 portion that was holding the hydrogen side roof 18.

For this reason, the leaked hydrogen gas is prevented from going to the fixed refueling area A1 by the roof door 72 depending on the roof end of the hydrogen side roof 18, and diffuses upward through the ventilation port 73 of the opened hydrogen side roof 18. It is possible to prevent hydrogen gas from entering the refueling equipment area A1 and causing a fire that leads to a large-scale fire. In other words, the synergistic effect of the roof door 72 depending on the roof end of the hydrogen side roof 18 and the open ventilation opening 73 ensures that hydrogen gas enters the refueling equipment area A1 and becomes a fire factor leading to a large-scale fire. It can be prevented.

  The opened roof door 72 is returned to the closed position, for example, by connecting one end of a wire to the tip of the roof door 72 and passing through a roller disposed on the winding drum provided on the lower side of the column 54. The other end of the wire drawn in is connected, and the roof door 72 is pulled up to a position where it is held by the latch portion 75 and closed by the wire movement of the winding drum by the handle operation.

The ventilation tower 90 may be natural ventilation, or may be provided with a ventilation fan if necessary.

  The shutter device 60 normally lowers the shutter door 62 of the shutter device 60 to a predetermined height that does not obstruct the passage of the automobile under the control of the control panel 35 shown in FIG. The hydrogen gas leaked from the 14 side is blocked by the shutter door 62 and diffuses upward from the ventilation tower 90 so that it is difficult to enter the fuel supply facility area A1.

On the other hand, when hydrogen gas leaks out or a fire breaks out, the shutter door 62 of the shutter device 60 is lowered to the station site surface, and the refueling facility area A1 and the hydrogen facility area A2 are shut off by the shutter door 62 and mutually. It is possible to prevent a fire factor. Further, even when the operation of the station is terminated, the operation may be performed such that the shutter door 62 is lowered to the site surface and the fueling facility area A1 and the hydrogen facility area A2 are partitioned.

[Water pressure driven embodiment]
(Ventilation fan water pressure drive)

Then, the water turbine 93 is rotated by the water flow flowing through the water pressure driving unit 92 at this time, and the ventilation fan 58 connected to the drive shaft of the water wheel 93 is rotated for ventilation.

Since the ventilation fan 58 is operated by water pressure in this way, no electric motor is used to rotate the ventilation fan 58 , so that no spark is generated, and ignition on the roof side is suppressed and the operation can be performed safely. In addition, you may make it connect to a drain pipe, without providing the water spray head 48 in the outflow side of the hydraulic-pressure drive part 92. FIG.

  Further, as another embodiment of the disaster prevention monitoring system for hydraulically driving the ventilation fan shown in FIG. 15, an electric valve for water spraying is provided in the water supply pipe of the water spray head 48 that is the tip of the branch point of the water supply pipe from the fire pump 76. When the control panel 35 determines that hydrogen gas is detected by, for example, the hydrogen detector 38, the fire extinguishing pump 76 is activated and the water pressure is driven. It is also possible to control the opening of the motor-operated valve so that fire-extinguishing water flows from the water pressure drive unit 92 to the water spray head 48 and the ventilation fan 58 is rotated by the water wheel 93 to perform ventilation.

On the other hand, when the control panel 35 determines flame detection by the flame detector 36 , for example, the fire extinguishing pump 76 is activated and the water spraying motor is opened and pressurized fire extinguishing water is supplied from the water spray head 48. The storage facility 25 is sprayed with water and cooled. As described above, when flame detection is determined by the control panel 35, the ventilating fan 58 may be rotated by simultaneously opening the water pressure driving motor-operated valve.

  The point that the motor valve for water pressure driving and the motor valve for water spraying are provided and controlled individually is the same for the water pressure driving of the shutter device and the latch unit described later.

(Water pressure drive of shutter device)

  As shown in FIG. 17, a shutter device 60 is provided at the roof end of the oil supply side roof 16 provided in the fixed oil supply facility 12 opposite to the hydrogen side roof 18. A water pressure driving unit 92 having a water wheel 93 is installed on one side of the shutter device 60, and a water supply pipe from the fire extinguishing pump 76 of the water spray pump equipment 44 shown in FIG. 14 is branched to enter the water pressure driving unit 92. The water spray head 48 is connected to the outlet of the water pressure drive unit 92 via a pipe.

The rotation of the water wheel 93 provided in the water pressure driving unit 92 is transmitted to the shutter device 60 via the speed reducer 94, and the fire extinguishing water pressurized from the fire pump is discharged from the water spray head 48 through the water pressure driving unit 92, At this time, the water wheel 93 is rotated by the water flow flowing through the water pressure drive unit 92, decelerated by the speed reducer 94, and the shutter device 60 is rotationally driven, and the shutter door 62 is lowered to a predetermined height that does not hinder the movement of the automobile. To do.

  Since the shutter device 60 is actuated by water pressure in this way, no electric motor is used to drive the shutter device 60, so that no spark is generated, and ignition on the roof side is suppressed and the shutter device 60 can be operated safely. In addition, you may make it connect to a drain pipe, without providing the water spray head 48 in the outflow side of the hydraulic-pressure drive part 92. FIG.

  Further, the hydraulic drive unit 92 for the shutter device 60 of the present embodiment can be applied to the rotation of the roof door 68 shown in FIG. 11 by restricting the rotation range to 90 °.

When the cylinder chamber 95 is supplied, the piston 96 is stroked to the right against the return spring 98 by pressurization of the cylinder chamber 95, and the rotation lever 67 is pushed by the rod 97 to rotate clockwise as indicated by an imaginary line. Then, the holding of the latch portion 66 is released, and, for example, as shown in FIG. 10B, the damper plate 65 is rotated downward and suspended from the roof end.

  At this time, the amount of water regulated through the orifice 99 flows to the drainage side, but since the water supply from the pump side is sufficiently performed, the piston 96 can reliably stroke to the latch release position.

  In addition, when the supply of fire-extinguishing water from the fire-extinguishing pump is stopped, the pressurized water in the cylinder chamber 95 is discharged to the drainage side through the orifice 99, and the piston 96 is latched by the rotary lever 67 by the return spring 98 and the latch portion 66. To the initial position where it can be latched.
