Description

[Detailed description of the invention] [Field of industrial application] This invention is a diving system for retrieving submersible vessels (including submersible structures such as submersibles) from the seabed and rescuing them. Concerning a ship rescue buoy device.

[Conventional technology]

As shown in FIGS. 5 and 6, when the submersible 12 is in distress and sitting on the seabed B, the rescue of the submersible 12 is conventionally carried out in the following steps.

First, the rescue buoy 25 is detached from the submersible 12 via the rescue rope 23 and floated to the surface, thereby informing the mother ship 2 on the sea surface W of its position.

Then, the rescue buoy 25 is recovered on the mother ship 24, and the rescue rope 23 anchored to the rescue buoy 25 is pulled up onto the mother ship 24.

Next, the fitting alloy 22 is lowered from above the mother ship 24 to the submersible vessel 12 using the rescue rope 23 as a guide.
A lifting cable 21 is coupled to this fitting alloy 22, and when the fitting alloy 22 is fitted with a submersible boat side fitting alloy 26 on the upper part of the submersible 12, the lifting cable 21 is connected to the submersible. It is connected to a ship 12.

Thereafter, the submersible is recovered by winding up the recovery cable 21 and rescued.

[Problem that the invention attempts to solve]

However, although such conventional submersible rescue means are effective for rescuing the submersible 12 diving at shallow depths, when rescuing the submersible 12 diving at deep depths, it is necessary to In order to float the rescue buoy 25 up to this point, a long rescue line 23 commensurate with the depth is required. This rescue line 23
Naturally, a resistance force acts on the rescue buoy 25 due to water flow, etc., and this force acts in the direction of pulling the rescue buoy 25 into the water, so the buoyancy of the rescue buoy 25 must be made considerably large.

Furthermore, as described above, if the rescue line 23 is lengthened and a large rescue buoy 25 is installed in order to obtain sufficient buoyancy, the submersible 12 itself becomes large and the maneuverability of the submersible 12 is reduced. This results in damage.

Therefore, a submersible rescue method as shown in Figure 7 has been considered. That is, the submersible 12 that is in distress and has sunk on the seabed B floats the rescue buoy 14 from above via the rescue cable 13 as a buoy cable to a required height (the length of the rescue cable 13). At the same time, the acoustic oscillator 15 notifies the mother ship 1 and the rescue ship 2 on the sea surface W of the position.

These mother ship 1 and rescue ship 2 carry a chain-shaped weight 1 near where the submersible ship 12 is located.
The hoisting cables 3 and 3 each having a 0 at the tip are hung down.

The lower ends of these lifting cables 3, 3 are connected to the tangle cable 11.
The leash rope 11 is provided with a plurality of weights 10, a plurality of floats 5 with acoustic oscillators, and a leash rope float 6 at regular intervals depending on the length of the leash rope. And, the above-mentioned entanglement rope 11 is
The weight 10 and the floats 5 and 6 are arranged so as to be located at a required height from the seabed B, that is, at a level lower than the height at which the rescue buoy 14 is located.

In this state, the mother ship 1 and the rescue ship 2,
Using the acoustic positioning devices 16a and 16b, the acoustic signals from the acoustic oscillator-equipped float 5 and the acoustic oscillator 15 of the submersible vessel 12 are monitored, and while the positional relationship between the submersible vessel 12 and the entanglement line 11 is grasped, the hoisting and retrieval line is carried out. 3 and the entanglement rope 11 to bring it closer to the rescue buoy 14.

Next, by towing the entanglement line 11 by the mother ship 1 and the rescue boat 2, the entanglement line 11 comes into contact with the rescue line 13 and the rescue buoy 14, and this state is brought into contact with the acoustic positioning devices 16a and 16b. Once the measurements and judgments have been made, the mother ship 1 and the rescue boat 2 are maneuvered so that both ends of the tether 11 cross each other, and the tangle 11 is entangled with the rescue rope 13 and the rescue buoy 14 and engaged. . And mother ship 1 and rescue ship 2
, the submersible 12 is brought to the sea surface W by winding up the recovery line 3, the entanglement line 11, and the rescue line 13.
It is pulled up to the top and collected.

In addition, in FIG. 7, the reference numeral 8 indicates a floating cable. According to such means, even if the submersible 12 to be rescued is on the deep seabed B, the submersible 12 can be reliably lifted and retrieved, and regardless of the diving depth of the submersible 12, it can be rescued at a certain level. Submarine 1 with length of rescue line 13
Since the second rescue can be performed, the rescue rope 13 can be shortened and the rescue buoy 14 can be downsized.

Therefore, the space occupied by the rescue buoy 14 inside the submersible 12 can be reduced, and the space occupied by the rescue buoy 14 can be reduced.
In addition to being able to effectively use the space and payload inside the submersible, the miniaturization of the rescue buoy 14 also makes it possible to downsize the submersible itself.
In this case, the maneuverability of the submersible can be improved.

However, in such a submersible rescue method, in order to bring the entanglement rope 11 into contact with the rescue rope 13 and the rescue buoy 14 and then pull it up above the sea surface W, the entanglement rope 11 must not fall off from the rescue buoy 14. Therefore, it is necessary to maneuver the mother ship 1 and the rescue boat 2 to wrap the entanglement rope 11 around the rescue rope 13 and the rescue buoy 14. The deeper the depth of the submersible vessel 12, the longer the maneuvering time.

Submersible rescue operations involve human lives and must be carried out in as short a time as possible within the duration constraints of the emergency equipment inside the submersible 12, so it is undesirable to waste time on vessel maneuvering operations as described above. .

The present invention aims to solve these problems, and even when a rescue buoy that has been detached from a submersible on the deep sea floor does not rise to the sea surface, it is possible to easily and safely transport the submersible in a short time. The purpose of the present invention is to provide a buoy device for the rescue of submersibles that can be retrieved.

[Means for solving problems]

For this reason, the submersible rescue buoy device of the present invention is
At a rescue buoy that is connected to a submersible on the ocean floor via a buoy cable, the buoy is moved diagonally downward from the buoy in order to ensure engagement between the buoy cable and the buoy itself and the entanglement cable from the ship at sea. It is characterized in that it is equipped with a plurality of protruding locking legs, and a closing rod that opens only upwards is mounted between the mutually adjacent locking legs.

[Effect]

In the above-described submersible rescue buoy device of the present invention, a tangle line from a ship at sea pushes up a closure rod and is guided between the tangle legs. At this time, since the closing rod is opened only upward, the engagement of the tangling rope with the buoy rope and the buoy itself is ensured.

〔Example〕

Hereinafter, a submersible rescue buoy device as an embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a side view thereof, Fig. 2 is a sectional view taken along the - arrow in Fig. 1, and Figs. 3 and 4. Both are schematic diagrams for explaining the outline of a submersible ship rescue procedure using the same device.

As shown in FIGS. 1 and 2, in this embodiment, a plurality of rescue buoys 14 (in this embodiment, 8) entangled legs 17, 17a,
The lower surface of the buoy 14 projects obliquely downward.

These tangling legs 17 and 17a are arranged alternately at 45° intervals, and at the tip of the twining leg 17, a closing rod 18, 18 is provided between the twining leg 17 and the adjacent twining leg 17a, 17a. It is pivotally connected by a connecting pin 19 so that it is mounted on.

Further, a closing rod stop 20 is provided at the tip of the locking leg 17a, and this closing rod stop 20 is
On its upper side, the adjacent twining legs 17,1
It comes into contact with closing rods 18, 18 mounted from 7, and restricts these closing rods 18, 18 to open only upward.

In addition, in FIGS. 1 and 2, the reference numeral 14a indicates a connecting member that connects the rescue buoy 14 and the rescue rope 13.

Since the submersible rescue buoy device as an embodiment of the present invention is constructed as described above, submersible rescue operations using the device are carried out in the following steps.

That is, as shown in FIG. 3, the submersible 12 that was in distress and sank on the seabed B is connected to the entanglement legs 17, 1 via the rescue line 13 as a buoy line from above.
The rescue buoy 14 having the buoy 7a and the closing rod 18 is floated and placed at the required height (the length of the rescue line 13), and the acoustic oscillator 15 is used to notify the mother ship 1 and the rescue ship 2 of its position on the sea surface W. Let me know.

These mother ship 1 and rescue ship 2 carry a chain-shaped weight 1 near where the submersible ship 12 is located.
The hoisting cables 3 and 3 each having a 0 at the tip are hung down.

The lower ends of these lifting cables 3, 3 are connected to the tangle cable 11.
The leash rope 11 is provided with a plurality of weights 10, a plurality of floats 5 with acoustic oscillators, and a leash rope float 6 at regular intervals depending on the length of the leash rope. And, the above-mentioned entanglement rope 11 is
The weight 10 and the floats 5 and 6 are arranged so as to be located at a required height from the seabed B, that is, at a level lower than the height at which the rescue buoy 14 is located.

In this state, the mother ship 1 and the rescue ship 2,
While observing the acoustic signals from the acoustic oscillator-equipped float 5 and the acoustic oscillator 15 of the submersible vessel 12 using the acoustic positioning devices 16a and 16b, and grasping the positional relationship between the submersible vessel 12 and the entanglement line 11, as shown in FIG. As shown in , the hoisting line 3 and the entanglement line 11 are towed close to the rescue buoy 14.

Then, by towing the twine 11 by the mother ship 1 and the rescue ship 2, as shown in FIG.
The tangle line 11 and the rescue line 13 come into contact with each other and are pulled further, so that the tangle line 11 rises while maintaining contact with the rescue line 13.

In this way, the entanglement rope 11 is connected to the rescue buoy 1.
When reaching the lower part of the rescue buoy 14, the leash 11 contacts the closing rod 18 of the rescue buoy 14 and applies a pushing force to the closing rod 18, as shown in FIG.

This pushing up force causes the tether 11 to push up the closing rod 18 and fit within the tangled legs 17, 17a below the rescue buoy 14.

At this time, the pushed-up closing rod 18 returns to its original position under its own weight when the rope 11 is raised and the rope 11 is housed within the rope legs 17, 17a, to prevent the rope 11 from coming off. Engages with the closing rod stop 20.

The closing rod 18 is arranged 360° around the entanglement legs 17 and 17a, so that no matter what angle the entanglement rope 11 rises from, it stays below the rescue buoy 14 and prevents the entanglement rope 11 and the rescue line 13 from rising. And engagement with the rescue buoy 14 is ensured.

When the tangle line 11 is settled in this way, the mother ship 1 and the rescue ship 2 pull up the rescue hoisting line 3 and pull up the submersible vessel 12 together with the tangle line 11 and the rescue buoy 14 above the sea surface W. and collect it.

In addition, in FIG. 3, the reference numeral 8 indicates a floating cable.

In this way, according to this embodiment, the entangled leg 1
7, 17a and the closing rod 18, the entanglement cable 11, the rescue cable 13 and the buoy 14
Since the engagement with the rescue line 13 is easily ensured, the tangle line 11 can be easily connected to the rescue line 13 by maneuvering the mother ship 1 and the rescue vessel 2.
There is no need for the submersible to be entangled with the submersible vessel 12, etc., and the submersible vessel 12 can be recovered and retrieved only by navigating straight ahead.

Therefore, the evacuation and rescue work of the submersible vessel 12 can be carried out in an extremely short time.

[Effect of idea]

As described in detail above, according to the submersible rescue buoy device of the present invention, in a rescue buoy that is connected via a buoy cable to a submersible sunk on the seabed, the buoy cable and the buoy itself are connected to each other at sea. In order to secure engagement with the tangle line from the ship, the buoy is equipped with multiple tangle legs that project diagonally downward, and
With a simple configuration in which a closing rod that opens only upwards is installed between the adjacent tangle legs, engagement between the tangle rope and the buoy rope or the buoy itself can be easily ensured. Therefore, the submersible is recovered and
This has the advantage that rescue work can be carried out in an extremely short period of time.
