この発明は、海洋資料採取あるいは掃海作業等
の海上作業を、ヘリコプタの負荷を軽減し、長時
間行なえるようにした海上作業方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for maritime work that reduces the load on a helicopter and allows maritime work such as marine data collection or minesweeping to be carried out for long periods of time.

負荷が増大し、長時間の作業を行なうこができな
い。 Conventionally, maritime operations such as collecting marine data or minesweeping at sea have been carried out using marine vessels, and in this case, long-term operations are possible with equipment loaded on the vessel. However, due to the characteristics of the ship, it is not possible to rush to the site. On the other hand, when using a helicopter, it is possible to rush to the work location in an emergency, but compared to ships, there are significant restrictions in terms of the amount of fuel that can be carried, and heavy objects cannot be loaded onto the helicopter while working at sea. Doing so increases the load on the helicopter, making it impossible to carry out long-term operations.
この発明は、前記の点に留意してなされたもの
であり、つぎにこの発明を、その１実施例を示し
た図面とともに、詳細に説明する。 This invention has been made with the above points in mind, and will now be described in detail with reference to drawings showing one embodiment thereof.

ローラ１０に予め通されている。 As shown in FIG. 1, a platform 2 is suspended from a helicopter 1 by a suspension cable 3, and a winch 5 containing a towing cable 4 and a winch 7 containing a working electric wire 6 are installed in the warehouse of the helicopter 1.
The guide cable 8 connected to the tip of the electric wire 6
Then, the towing cable 4 is led out from the rear opening door of the helicopter 1, and the tip of the towing cable 4 is connected to the tip of the platform 2, and the tip of the guide cable 8 is connected to the tip of the platform 2, as shown in FIG. It is previously passed through a pair of unwinding rollers 10 in a boom 9 at the bottom of the platform 2.

止する。 Next, the helicopter 1 moves forward at a slow speed and gently tows the platform 2 by the towing cable 4, as shown in FIG. At this time, the water wheel 11 installed below the water surface of the platform 2 is rotated by the water flow, the unwinding roller 10 connected to the water wheel 11 is rotated, and the guide rope 8 is sent out to the rear of the platform 2 by the roller 10. , the electric wire 6 connected to the guide rope 8 is also sent out rearward. Then, as shown in FIGS. 3 and 4, the electric wire 6
When the rear end 12 reaches the position of the boom 9, the rear end 12 comes into contact with the roller 10 and acts as a stopper. Note that the lifting cable 1 is attached to the rear end 12 of the electric wire 6.
3, and the lifting cable 13 is let out from the winch 7. When the rear end portion 12 of the electric wire 6 comes into contact with the boom 9, the force applied to the boom 9 suddenly increases due to the resistance of the electric wire 6 due to the water flow. This change appears as a change in the tension of the towing cable 4, and the tension is detected by the tension detector of the helicopter 1, and upon this detection, the helicopter 1 stops moving forward.

Rotate the boom 9 upwards into the recess 15 formed in the bottom, and insert the connector 16 in the recess 15 into the
The rear end portion 12 of the electric wire 6 is attached. This connector 1
6 has a structure that automatically becomes watertight when the rear end portion 12 is attached, and the electric wire 6 is energized by a generator 14. Note that after the rear end portion 12 is attached to the connector 16, the boom 9 automatically rotates and returns to its original position to be in a fixed state.

hovers and tow cable 4 and lifting cable 1
At the same time, the boom 9 is rotated into the recess 15 under the control from the helicopter 1, the connector 16 and the rear end 12 are disconnected, the boom 9 is returned to its original position, and the tow cable 4 is The winding is stopped after leaving an appropriate length, and the hoisting cable 13 is continuously wound, and the electric wire 6 and the guide rope 8 are also wound all at once. After that, with the tow cable 4 and guide rope 8 slackened, the suspension cable 3 is suspended from the helicopter 1, and the hook at the tip of the suspension cable 3 is connected to the pantograph-like lifting fitting 2' on the platform 2. Then, the hanging cable 3 is wound up to a predetermined length using a winch and returned to the base.
つぎに、海上作業の具体例について説明する。 Next, a specific example of maritime work will be explained.

して曳航するが望ましい。 A current is passed through a generator 14 of the electric wire 6 to generate magnetism, perform magnetic sweeping, and ignite a magnetically sensitive mine under the sea or on the seabed. At this time, it is desirable to tow platform 2 150 to 200 meters away to avoid the risk of mine explosion.

御しやすい。 Further, in the case of collecting marine materials, a hose is used as a long work body instead of the electric wire 6, and the materials are stored in the platform 2 from the suction port at the tip of the hose by a pump mounted on the platform 2. Further, when it is necessary to position the suction port at a predetermined depth, a weight is attached to the tip of the guide cable 8. In the case of this data collection, the shorter the length of the towing cable 4 for towing the platform 2, the easier it is to control.

海上作業方法である。 As described above, the present invention includes loading work equipment such as a generator and a pump on a platform, suspending the platform from a helicopter using a suspension cable, and connecting the tip of a towing cable in the helicopter to the platform. Then, at the offshore work site, the suspension cable is lowered, the platform is landed in the water, the platform is towed by the towing cable, and long work objects such as electric wires and hoses are transported from the helicopter through the platform. A method for working at sea, characterized in that the elongated work body that has been fed out onto the sea is connected to the work equipment under control from the helicopter, and the work equipment is driven to perform the work at sea. be.

る。 Therefore, according to the present invention, since heavy work equipment such as generators and pumps required for sea work is loaded on the platform, it is only necessary to tow the heavy goods during sea work, and the helicopter is not required to carry out the work. This reduces the load on the person and allows them to work for long periods of time. In addition, long working objects such as electric wires and hoses are fed out from the helicopter via the platform, and under control from the helicopter, the long working objects are connected to the working equipment and the working equipment is driven. Work can be done smoothly.
