Description

[Detailed description of the invention] [Industrial application field] This invention is a diving system for rescuing submersible vessels (including submerged structures such as submersibles) from the seabed. 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 released from the submersible 12 via the rescue cable 23 and floated to the surface, thereby informing the mother ship 24 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 fitting alloy 26 on the side of the submersible on the upper part of the submersible, 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, while such conventional rescue means for submersible vessels is effective for rescuing a submersible vessel 12 that dives at shallow depths, when rescuing a submersible vessel 12 that dives at great depths, a rescue line 23 long enough to correspond to the depth is required to raise the rescue buoy 25 from the ocean floor B to the sea surface W.
Naturally, resistance due to water currents and the like acts on the rescue buoy 25, and this force acts in a direction that pulls 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,
The acoustic positioning devices 16a and 16b monitor acoustic signals from the acoustic oscillator-equipped float 5 and the acoustic oscillator 15 of the submersible 12, and while grasping the positional relationship between the submersible 12 and the entanglement line 11, hoisting and retrieving the line. 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. .

Then, the submersible vessel 12 is raised above the sea surface W and retrieved by winding up the recovery line 3, the entanglement line 11, and the rescue line 13 in the mother ship 1 and the rescue vessel 2.

In Fig. 7, the reference numeral 8 denotes a floating line. With such a means, even if the submersible vessel 12 to be rescued is on the deep seabed B, the submersible vessel 12 can be reliably salvaged. Furthermore, the submersible vessel 12 can be safely retrieved by the rescue line 13 of a fixed length regardless of the diving depth of the submersible vessel 12.
Since rescue of the second type can be performed, the rescue line 13 can be shortened and the rescue buoy 14 can be made compact.

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. Equipped with multiple protruding legs that can be folded,
A closing rod is pivotally attached to the lower end of each of these tangling legs, and a connecting member between the buoy and the buoy rope supports the free end of the closing rod and prevents downward rotation of the closing rod. It is characterized by being equipped with an attached closing rod receiver.

[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〕

Below, a submersible rescue buoy device as an embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a longitudinal sectional view thereof, Fig. 2 is a sectional view taken along the - arrow in Fig. FIG. 4 is a longitudinal cross-sectional view showing a state in which the device is stored in a submersible, and is a schematic diagram for explaining the outline of a submersible rescue procedure using this device.

As shown in FIGS. 1 to 4, in this embodiment, a plurality of rescue buoys 14 (in this embodiment, so that the four (4) entanglement legs 17 protrude obliquely downward from the lower surface of the buoy 14,
It is foldably pivoted by a pin 17a.

At the lower end of each of these tangling legs 17 is a closing rod 1.
8 is pivotally mounted by a pin 18a, and the free end of this closing rod 18 is provided with a coupling member 14a, which will be described later.
A bifurcated engaging portion 18b is formed which can be engaged with the closing rod receiver 19 using as a guide.

And, at the bottom of the rescue buoy 14, the same buoy 1
4 and the rescue line 13 is attached, and a closing rod receiver 19 supports the engaging portion 18b at the free end of the closing rod 18 at the lower part of this connecting member 14a, and It is attached to prevent downward rotation.

Further, a spring receiver 20a is attached to the upper part of the coupling member 14a, and a spring receiver 20b and a spring 20c are interposed between the spring receiver 20a and the buoy 14. A locking leg support metal fitting 20d is interposed between the spring receiver 20b and each locking leg 17, and the spring 20c
The binding leg 17 is urged in the opening direction by the urging force.

Therefore, the tangle leg 17 is connected to the recess 12a of the submersible 12 of the rescue buoy 14 as shown in FIG.
When stored inside, the rescue buoy 14 is folded within the outer diameter range, but when the rescue buoy 14 is launched, it is quickly pushed out by a spring 20c, as shown in Fig. 1. .

As shown in FIG. 3, when the rescue buoy 14 is stored, the excess length of the rescue cable 13 is wound up by a winding machine 27 inside the submersible vessel 12.

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. 4, a submarine 12 that has been in distress and has sunk on the seabed B is connected to a rescue buoy having an entanglement leg 17 and a closing rod 18 from above via a rescue cable 13 as a buoy cable. 14 is floated and placed at a required height (length of the rescue rope 13), and the acoustic oscillator 15 notifies the mother ship 1 and the rescue ship 2 on the sea surface W of its 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,
While observing 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 tangle line 11 by the mother ship 1 and the rescue boat 2, the tangle line 11 and the rescue line 13 come into contact with each other, and by further towing the tangle line 11, the rescue line 13 comes into contact with the tangle line 11. It rises while maintaining the contact state.

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 into the tangle leg 17 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 entangled rope 11 is accommodated within the entangled leg 17 due to the rise of the entangled rope 11, and the closing rod 18 is pushed up to prevent the entangled rope 11 from coming off. Bifurcated engaging portion 18b and closing rod receiver 19 at the free end of 18
and are engaged.

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. 4, the reference numeral 8 indicates a floating cable.

In this way, according to this embodiment, the entangled leg 17
By providing the locking rod 18, the engagement of the entanglement line 11 with the rescue line 13 and the rescue buoy 14 is easily ensured. 13 etc. is no longer necessary, and the submersible 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.

Further, in this embodiment, since the tangling leg 17 is foldable, the recess 1 of the submersible 12
When the device is stored inside the submersible vessel 2a, the device itself becomes compact, and the space inside the submersible vessel 12 can be used effectively.

[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 a tangle line from a ship, a plurality of tangle legs projecting diagonally downward from the buoy are foldably equipped, and a closure is pivotally attached to the lower end of each of these tangle legs. The system is equipped with a rod and a closing rod holder attached to the connecting member between the buoy and the buoy cable in order to support the free end of the closing rod and prevent downward rotation of the closing rod. With a simple configuration, engagement between the entanglement cable and the buoy cable or the buoy itself can be easily ensured, making it possible to carry out salvage and rescue work for the submersible in an extremely short time.

Furthermore, since the device is stored in the submersible with the tether legs folded, the device itself does not occupy a large amount of space inside the submersible, which has the advantage of making effective use of the space.
