Abstract

PURPOSE:To salvage an unnavigated submarine boat from the seabed speedily and easily, by installing an arm being retractable to a submarine boat body and having a projecting member at the tip, while winding a sling rope round the said arm by a diving machine being controlled from a mother ship. CONSTITUTION:A retractable arm 6 is built in a submarine boat 1, and usually it is housed in a body of the submarine boat 1 in advance as a full line, and at time of emergency, a hydraulic drive unit is operated and the arm 6 is projected as in a dotted line. On the other hand, at the time of salvaging this submarine boat 1, an unmanned diving machine 4 is controlled from the side of a mother ship in a state of attaching a sling rope 5, and it sails around the arm 6 projected to the hull upper part several times and, after the sling rope 5 is wound round the arm 6, this unmanned diving machine 4 is pulled up onto the mother ship. When the sling rope wire 5 is pulled out from top of the mother ship, the slig rope wire 5 is prevented from coming off the arm 6 due to a projecting member 8 at a tip of the arm 6. Owing to suchlike constitution, winding of the slig rope wire 5 by the unmanned diving machine 4 is speedily and easily performable.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a submersible rescue device, more specifically, a submersible rescue device for rescuing a submersible that is unable to navigate due to a distress or unexpected accident in a relatively deep sea area. This relates to a submersible rescue device for raising a submersible.

[Prior art]

In recent years, ocean development has been actively carried out, and the ocean areas are increasingly reaching deeper waters.

In this ocean development, it is first necessary to survey the area, and submersibles are usually used for this survey. By the way, if this submersible becomes unable to navigate due to an unexpected accident or distress during work or navigation, it will be necessary to pull it out. For this reason, conventionally, as shown in Fig. 6, a lifting piece 2 was attached to the submersible in advance.
is attached, and if the submersible 1 becomes unable to navigate, there is a method in which the unmanned submersible 4 having the manipulator 3 is operated from the mother ship (not shown) and the lifting cable 5 is secured to the piece 2 by the manipulator 3. It had been taken.

However, according to this method, since the piece 2 always protrudes above the submersible 1, it is formed of a small member in consideration of resistance and occurrence of contact accidents while the submersible 1 is running. In order to secure the lifting cable 5 using the piece 2 hemomanipulator 3, which is a small member, a fairly accurate remote control is required, and a large amount of time is required. This is a serious problem for submersible rescue, which requires early rescue.

[Purpose of the invention]

The present invention has been made to solve the above-mentioned conventional problems, and its purpose is to quickly and easily rescue a submersible that has become unable to sail from the seabed. .

[Summary of the invention]

In order to achieve the above-mentioned object, the present invention provides an arm that can be retracted from the main body of a submersible and has a protruding member at its tip, and a lifting cable is wound around the arm by a submersible operated from a mother ship. The purpose of this project is to provide a submersible rescue device that can be used in a variety of ways.

The present invention prevents a lifting member from constantly protruding outside the submersible body, and is provided with a member that is normally housed within the submersible body and protrudes as needed. . This protruding member is provided at the arm and the tip of the arm, and either is in an expanded state or has the function of being expanded and expanded as necessary.

[Embodiment] Hereinafter, an embodiment of a submersible rescue device according to the present invention will be described based on FIGS. 1 to 5.

FIG. 1 is a side view of the submersible 1, which has a built-in arm 6 that can be retracted. As shown in FIG. 2, this arm 6 is formed as a rond of a hydraulic piston 7, and a disc-shaped or rod-shaped protruding member 8, which forms the outer shell 1' of the submersible 1111, is fixed to the tip of the arm 6. ing.

Normally, the arm 6 is stored in the main body of the submersible as shown by the solid line, and in case of an emergency, a hydraulic drive device (not shown) is operated to cause the arm 6 to protrude as shown by the dotted line.

On the other hand, when rescuing this submersible 1, as shown in FIG. The unmanned underwater vehicle 4 is sailed around the submarine 6 several times, and the lifting cable 5 is wound around the arm 6, after which the unmanned underwater vehicle 4 is pulled up to the mother ship.

When lifting the lifting cable 5 from the mother ship, the protruding member 8 at the tip of the arm 6 acts as a stopper, and the lifting cable 5
Since the submersible can be prevented from coming off the arm 6, the submersible 1 can be pulled up onto the mother ship.

FIG. 4 shows another shape of the protruding member 8 provided at the tip of the arm 6. In this case, the protruding member 8 is attached to a plurality of rod-shaped bodies 10 through attachment members 9 at the tip of the arm 6. is configured to be rotatable in the direction of arrow a-a' by a pin 11. A compression spring 12 is arranged between the arm 6 and the rod-shaped body 10. 13 is a guide attached to the tip of the rod-shaped body 10. The projecting member of this embodiment has a kind of umbrella bone structure, and FIG. 4 shows this bone in a reduced state.

With the protruding member 8 having the above structure, when the arm 6 is unexpectedly protruded from the submersible 1, the rod-shaped body 10 rotates around the bottle 11 due to the action of the compression spring 12 and unfolds as shown in FIG. . And as mentioned above, unmanned submarine 4
By manipulating the rod-like body 10 to wind the lifting cable 5 around the arm 6, the rod-shaped body 10 becomes a stopper, and the submersible boat 1 can be pulled up.

Of course, the driving device for the arm 6 is not limited to hydraulic pressure, and other fluid pressures such as pneumatic pressure and water pressure may be used, and it is clear that mechanical means such as a rack and pinion may also be used.

〔Effect of the invention〕

As is clear from the above description, according to the submersible rescue device according to the present invention, the arm 6 and the protruding member 8 are stored inside the main body during normal navigation of the submersible 1, so that the resistance increases. There is no risk of contact accidents.

In addition, since the protruding material 1 is normally housed inside the submersible 1,
It is possible to use a relatively large one, and the unmanned underwater vehicle 4 can quickly and easily secure the five windings of the lifting cable, and as a result, the underwater vehicle 1 can be rescued quickly. be.
