Description

[0001] HELDECK HAVING FIRE FIGHTING DEVICE [0002]

The present invention relates to a helideck provided with a fire-fighting device, and more particularly to a helideck provided with a fire-fighting device moving along a rail at the outer periphery of a pile cigarette of a helideck.

Generally, offshore plants such as drill ship, FPSO (Floating, Production, Storage and Offloading) or vessels that need to stay in the sea for a long time should operate helicopter , Which necessitates the installation of Helideck on the player or stern.

The helideck may be comprised of a pancake portion forming a deck floor where the helicopter takes off and landing and a pancake support portion supporting the pancake portion. The pancake part may be formed by connecting a plurality of plank to each other so as to support the helicopter. The pancake support may include H-shaped beams capable of supporting the pancake portion.

For example, the pancake portion may be formed by connecting a plurality of flank of aluminum material extending in one direction. Further, the pancake supporting portion includes a plurality of aluminum H beams extending long in a direction intersecting the extending direction of the flanks and disposed below the flanks to support the pancake portion, an aluminum H beam extending long in a direction intersecting the extending direction of the aluminum H beam, And a plurality of steel H beams disposed below the beam to support the aluminum H beam.

A landing pad having a fire extinguisher, which is a background of the present invention, includes a plurality of interlocking units, each interlocking unit having a landing surface, a sprinkler nozzle installed at the center of each interlocking unit, Water, sea water or foam).

However, since the conventional landing pad with a fire extinguisher has all the sprinkler nozzles displayed on the upper surface of the landing pad and dispersedly arranged, the impact of the wheels of the landing gear due to the contact of the helicopter upon landing becomes the landing pad or the sprinkler of the landing pad As it can be delivered to the nozzle, the sprinkler nozzle may fail and the sprinkler nozzle may not work properly in the event of a fire or the like, so that the fire can not be properly throttled.

In addition, since the fluid injection direction of the conventional sprinkler nozzle is injected in the vertical direction of the landing pad, the fluid injection direction can be changed by the side wind blowing from the sea or the roof, Since the position and direction of the sprinkler nozzle can not be aimed or changed to face the generating helicopter, the disaster prevention efficiency may be deteriorated in a windy environment.

Even when the helicopter landing on the landing pad of the prior art does not land at the center of the landing pad, which is the exact position of the landing pad, all of the interlocking units and the sprinkler nozzles operate simultaneously and the consumption of fluid droplets is relatively large , But it may not be effectively used to suppress the fire of the helicopter.

Hereinafter, the operation of the present embodiment will be described.

Referring to FIG. 3, the user can recognize that a fire has occurred on the pancake unit 100 of the helideck using the sensor device 401.

In this case, when the user opens the valve 330 by the manual method of operating the valve switch of the operation panel 410 of the control unit 400 or automatically opens the valve 330 when the fire occurs, The valve 330 is opened in an automatic manner, which is carried out by a predetermined process in itself, and at the same time the pump 340 can be operated.

In this case, the extinguishing medium of the storage tank W / T flows into the inner space of the fluid supply channel 310 via the pipe line 320, the pump 340, and the valve 330.

The extinguishing medium introduced into the fluid supply channel 310 under the pressure generated by the pump 340 flows through the third opening 311, the second opening 211 and the first opening 221, 220, respectively.

In addition, the extinguishing medium of the hollow body 220 may be injected through the injection nozzle 230 by the pressure.

The user controls the rotation direction of the pinion gear connected to the drive motor 270 so as to determine the direction of movement (F1, F2) of the hollow body 220 of the fire fighting apparatus 200 corresponding to the forward direction or the reverse direction of the rotation direction have.

4, when the wind direction W is blown from one side (for example, left side) to the other side (for example, right side) with respect to the center of the pancake part 100 of the helideck, The hollow body 220 can be moved on the rail 210 so that the injection nozzles 230 of the hollow body 220 are positioned on the right side of the pancake portion 100.

In this case, the extinguishing medium injected from the injection nozzle 230 can receive the wind blowing instead of receiving the backward wind, and can be sprayed farther, and a relatively large amount of extinguishing medium is delivered to the helicopter M It can help to suppress the fire.

5, the fire helicopter M can not land on the center side of the pancake unit 100 due to collision, and a fire can be generated while landing at a position off the center of the pancake unit 100.

In this case, the user also controls the rotation direction of the pinion gear of the drive motor 270 to move the hollow body 220 in the rail 210 to reach the vicinity of the fire generating helicopter M, The spray nozzle 230 of the fire-generating helicopter M can be disposed at a position close to the fire-generating helicopter M.

Thus, the extinguishing medium generated in the injection nozzle 230 adjacent to the fire-generating helicopter M can be more effectively used to extinguish the fire of the fire-generating helicopter M. [ In addition, the present embodiment can prevent the extinguishing medium from being sprayed from a relatively long distance and ineffectively consuming the fire suppression.
