This will be described in more detail.

The body 40 is formed in a cylindrical shape having a predetermined thickness and length, and a closed curved connection portion 42 for connection with the lifting rope 30 is formed at the upper end. The connecting portion 42 may be made of a ring, and a portion thereof may be integrated by welding to an upper end of the body 40 .

The lifting rope 30 is connected to the connecting portion 42 by a biner 32, a connecting ring, or a ring.

In this embodiment, the body 40 is shown and described in a cylindrical shape, but is not limited thereto and may be formed in a polygonal shape or a rod shape.

As shown in FIG. 4, the rope holding member 50 consists of 3 to 8 pieces and is radially arranged on the lower outer surface of the body 40. The rope hooking member 50 has a fixed end 52 coupled to the outer surface of the body 40 and an arc-shaped hooking support extending from the fixed end 52 so as to form an upwardly curved inner surface 54A. The ends of the hooking support end 54 form an arc-shaped hooking groove 58 that gradually narrows inward between the end 54 and the outer surface 56A and the inner surface 54A, which are circular or elliptical. It is configured to include a rope guide member 56 provided in the region.

The fixing end 52, the hooking end 54, and the rope guide member 56 may be integrally formed, and may be manufactured and then combined to be integrated.

The fixed end 52 may be integrally welded to the outer surface of the body 40 or may be integrally coupled by bolts or the like.

The hooking support end 54 has an arc shape that is curved upward and opened with reference to FIG. 5 . That is, after extending downward from the fixed end 52, it has an arc shape that is curved upward and opened upward. An inner locking surface 54A is formed inside the locking support end 54 . The inner locking surface (54A) is formed with a greater curvature than the rope guide member (56). This causes the rope guide member 56 to be biased and coupled to one side inside the inner locking surface 54A, so that a curved wedge-shaped locking groove 58 is formed between the outer locking surface 56A and the inner locking surface 54A. for it to form.

The rope guide member 56 has a circular, elliptical or non-spherical shape and is integrated with the above-described hooking support end 54 to form a wedge-shaped locking groove 58 between the hooking support end 54 and the rope guide member 56 . That is, in a state where the rope guide member 56 formed in a circular, elliptical or non-spherical shape is located on the curved inner hook surface 54A of the hook support end 54, a part of the rope guide member 56 is attached to the hook end 54. ) is integrated with the end of the The rope guide member 56 is coupled by being eccentric to one side inside the inner locking surface 54A as a whole. In this way, since the rope guide member 56 is coupled biased to one side (outside with reference to FIG. 5) from the inside of the inner locking surface 54A, a curved wedge between the locking support end 54 and the rope guide member 56 An engaging groove 58 of the shape is formed.

In addition, at the end of the rope guide member 56, guide projections for guiding the rope 20 located in water or on the surface to the locking groove 58 between the inner locking surface 54A and the outer locking surface 56A ( 56B) is formed protruding upward. The guide protrusion 56B and the outer locking surface 56A are connected by a connecting curved surface 56C. Therefore, when the rope 20 located on the sea floor or underwater or on the water surface is caught on the induction protrusion 56B, it is guided to the curved connection surface 56C and the outer locking surface 56A and inserted into the locking groove 58. it gets caught

As shown in Figs. 1 to 3, the rope guide member 56 has a through hole 56F formed in the center. In this way, since the through hole 56F is formed in the center of the rope guide member 56, the weight of the entire underwater rope collection device 10 can be reduced, especially when the underwater rope collection device 10 is brought into the water. The influence of ocean currents can be minimized. That is, when the through hole 56F is not formed in the rope guide member 56 and is formed in a plate shape, resistance to water occurs and it is difficult to move to a desired position due to the influence of currents or ocean currents, or each rope member By forming the through hole 56F in 56, the influence of tides or ocean currents can be minimized.

On the other hand, in the locking groove 58, the rope guide member 56 is biased to one side inside the inner locking surface 54A and coupled to the inner locking surface 54A of the locking support end 54 and the rope guide member 56. It is formed in a curved wedge shape between the outer locking surfaces 54A. Since the locking groove 58 is formed in a curved wedge shape, the rope 20 guided to the outer locking surface 56A smoothly moves to a narrow part (narrow area) without interference and is caught.

At this time, as shown in FIG. 6, the boundary between the inner locking surface 54A and both side surfaces 54B of the locking support end 54 is formed with a hooking edge 58A formed at a right angle, and an outer locking surface 56A. ) And the boundary between both side surfaces 56D of the rope guide member 56 are also formed at right angles to the hooking edge 58A. That is, the boundary between the inner locking surface 54A and both side surfaces 54B of the locking support end 54) and the boundary between the outer locking surface 56A and both side surfaces 56D of the rope guide member 56 are formed at right angles. Thus, right angle corners 58A are formed. In this way, since the sharp right angle edges 58A are formed at each boundary, each right angle edge 58A is caught and interfered with the rope 20 entering the rope 20 guided by the outer locking surface 56A and the inner guide surface 54A, so that the rope 20 ) maintains a solid locking state in the locking groove 58.

On the other hand, as shown in Figure 7, the outer locking surface (56A) and the inner locking surface (54A) constituting the locking groove 58 are guided to each corner of the hooking groove 58 and the rope 20 is caught. It is the same as the above-described embodiment except that the locking protrusions 58B are formed consecutively like sawtooth so that the state is fixed. At this time, it is preferable that the locking protrusions 58B are formed only on the narrow portion of the locking groove 58. This is to allow the rope 20 to be moved toward the narrow portion and caught without interference.

In this way, as the locking protrusions 58B are formed in the locking groove 58, each locking protrusion 58B digs into the surface of the rope 20 inserted into the locking groove 58, and thus the rope 20 is firmly hooked. state can be maintained.

The operation of the underwater rope collection device 10 according to the present invention configured as described above will be described.

As shown in FIG. 5, in a state where the lifting rope 30 is connected to the body 40 of the underwater rope collection device 10, the underwater rope collection device 10 is moved into the water where the rope 20 to be collected is located. take it in

Subsequently, when the underwater rope collection device 10 is towed, the rope 20 located in the water or on the surface is caught on the induction protrusion 56B.

As shown in FIG. 5, the rope 20 hooked on the induction protrusion 56B is guided to the connecting curved surface 56C and the outer hooking surface 56A through the expansion part (wide entrance area) of the hooking groove 58. It gets stuck while being inserted into the narrow part (narrow inner area).

When the rope 20 is inserted into the locking groove 58 and caught, each right angle corner 58A or the locking protrusion 58B on both sides is driven into the surface of the rope 20 and caught, so the rope 20 is hooked to the locking groove 58 will remain firmly attached to the

When the rope 20 is caught in the locking groove 58 in the above process, the lifting rope 30 is lifted to recover the marine equipment connected to the rope 20.

In this way, in the process of connecting the underwater rope collection device 10 to the lifting rope 30 and towing, the rope 20 located underwater or on the surface is firmly caught in the wedge-shaped locking groove 58, thereby collecting the rope ( 20) can be easily performed.

In particular, an induction protrusion 56B is formed at the end of the rope guide member 56, and the catching groove 58 is connected to the guiding protrusion 58B, so that the rope 20 caught on the guiding protrusion 56B is not interfered with the catching groove ( 58), the rope 20 can be hooked accurately and smoothly in the process of towing the collection device 10 to the seabed or underwater.
