Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, the well-known functions or constructions are not described in order to simplify the gist of the present invention.

FIG. 1 is an exploded perspective view illustrating a descending and collecting apparatus for a marine explorer according to the present invention, FIG. 2 is a perspective view of a coupled state of a descending and collecting apparatus for a marine explorer shown in FIG. 1, 3a and 3b are sectional views taken along the line AA of Fig.

As shown in Figs. 1 to 3B, a descending and collecting device for a marine explorer comprises a body 30 having a wing portion 32 for suppressing the rise of the underwater probe 10, The main traction cable 60 coupled to the shaft 41 and the shear pin 50 and connected to the lifting device of the radiation is coupled and an auxiliary traction cable 70 connected to the underwater probe 10 is coupled, The body 30 can be rotated while the shear pin 50 is broken when the body 30 is interfered with the underwater obstacle due to interference with the underwater obstacle so that the underwater obstacle can be avoided ).

This will be described more specifically.

The body 30 is formed in a plate shape having a narrow front part 31 and wider toward the rear part 33 and a wing part 32 is provided on both the middle area 35 and the rear part 33 do. Although the overall shape of the body 30 is configured to be similar to a triangle in the present embodiment, it is needless to say that the body 30 may be formed in various shapes.

An installation slot 34 is formed in the intermediate region 35 between the wing portions 32 so as to extend in the direction from the front portion 31 to the rear portion 33 and has an opening portion 34A opened toward the rear side. A weight portion 36 is provided on the bottom surface of the front portion 31 so that the center of gravity of the body 30 is located on the front portion 31 with respect to the shaft 41. 3A, the weight portion 36 is convexly formed on the bottom surface of the front portion 31, and the weight portion 36 is formed to be curved so as to be higher toward the bottom of the rear portion 33 do. The weight portion 36 can prevent the front portion 31 of the body 30 from being lifted upward during the pulling operation of the main traction cable 60 so that the rise of the body 30 can be suppressed .

On the upper surface of each wing portion 32 on both sides of the intermediate region 35, auxiliary wings 32A are provided perpendicularly to the surface of the wing portion 32 to prevent the body 30 from being shaken during pulling. That is, each of the auxiliary vanes 32A serves to balance the body 30 so that it does not shake when pulled.

3B, the wings 32 are formed at both sides of the middle region 35 of the body 30 at a predetermined angle inclination. This downward inclination is to lift the wing portion 32 from the horizontal force towed by the radiation, so that the lifting force generated in the wing portion 32 is directed toward the gravity direction. The downward tilting structure of the wing portion 32 allows the body 30 to be continuously downward along with the weight portion 36 when the irradiation line pulls the underwater probe 10, Function.

When the downward inclined structure of the wing portion 32 and the weight portion 36 do not exist, the downwardly facing underwater probe 10 is lifted up by the front portion 31 of the body 30, .

A weight portion 36 is provided on the bottom surface of the front portion 31 of the body 30 so that the center of gravity of the body 30 is located toward the front portion 31 with respect to the shaft 41. The weight portion 36 is for minimizing or preventing the rise of the body 30 by tilting the front portion 31 forward at a predetermined angle when the body 30 is pulled, Is formed to be convex on the bottom surface of the front portion 31 and is formed so as to be curved so as to be lower toward the bottom surface of the rear portion 33 with respect to the front portion 31 (with reference to the bottom surface). A heavy object can be placed inside the weight portion 36.

The towing frame 40 is formed with a front connecting portion 42 to which a main towing cable 60 connected to a winch of a radiation is connected at one end and an auxiliary towing cable 70 connected to the underwater exploration 10 at the other end is connected And an opening 34A is formed at a portion where the front connecting portion 42 is formed so as to be rotatably coupled with the shaft 41 in a state where the region where the front connecting portion 42 is formed is located in the mounting long hole 34 of the front portion 31, Is joined to the opening portion 34A side by the shear fin 50. [0064]

That is, the towing frame 40 connects the main tow cable 60, which is connected to the winch of the survey line (not shown), and the auxiliary tow cable 70, which is connected to the underwater survey 10, The pin 50 is broken and the body 30 is rotated to avoid an underwater obstacle. The shear pin 50 is broken when a load value greater than a predetermined load value acts on the pulling frame 40 due to interference of an underwater obstacle on the front portion 31 of the body 30, Is rotated forward and downward about the shaft 41 so as to escape from the water obstacle.

1, a front connecting portion 42 is formed in a front region, and a front connecting portion 42 is formed in such a manner that a shaft 41 is coupled A front coupling hole 42C for coupling the main traction cable 60 is formed on the protruding portion 42B protruded upward from the region where the shaft hole 42A is formed and a rear coupling portion 42C 44 are formed in the shape of "┓" with a rear coupling hole 44A to which the auxiliary traction cable 70 is connected. An engagement end 46 having a shear pin engagement hole 46A through which the shear pin 50 passes is protruded from the upper surface of the region located in the opening 34A. By this coupling end 46, the traction frame 40 is kept parallel to the upper surface of the body 30.

The reason why the projecting portion 42B is formed in the front connecting portion 42 and the rear connecting portion 44 is formed in the shape of a spindle is that the phenomenon of interference with the wing portion 32 during the pulling operation of the underwater probe 10 When the shear pin 50 is broken, the pull frame 40 is rotated downward about the shaft 41 and the body 40 is rotated forward about the shaft 41 So that an underwater obstacle can be easily avoided.

The traction frame 40 has a pair of front brackets 34B provided in the front region of the installation slot 34 and a pair of rear brackets 34C provided in the opening 34A. . That is, the lower region of the front connecting portion 42 is rotatably coupled to the shaft 41 in a state where it is positioned between the pair of front brackets 34B, and a state in which the connecting end 46 is positioned between the rear brackets 34C The shear pin 50 passes through the rear bracket 34C and the shear pin engagement hole 46 and is then coupled to the other rear bracket 34C.

At this time, a male screw portion is formed at one end of the shear pin 50, and a female screw hole is formed at the other rear bracket 34C, so that the shear pin 50 can be coupled to the female screw hole. This is to prevent the shear pin 50 from being detached. However, the present invention is not limited to this, and it is needless to say that they may be combined by a nut fastening structure. The shear fin 50 may be made of a synthetic resin material or a non-ferrous material having a low rigidity such that the shear fin 50 is broken when a predetermined load is applied.

The pull frame 40 is preferably formed in a hollow shape. This is for electrically connecting the radiation to the underwater probe 10 and to allow the signal cable provided in the main cable 60 to be connected to the underwater probe 10 through the interior of the draw frame 40 . On the other hand, a receiving groove for accommodating the signal cable in the longitudinal direction may be formed on the upper surface of the traction frame 40.

The pair of the front brackets 34B and the rear brackets 34C may be formed integrally with the body 30 or formed integrally with the body 30 by being formed separately from the body 30 or protruding from the body 30. [

The operation of the descending and collecting device for a marine exploration body constructed as above will be described.

FIG. 4 is a perspective view illustrating a state in which an underwater probe is connected to a descending and collecting apparatus for a sea explorer shown in FIG. 1, and FIG. 5 is a perspective view of the descending and collecting apparatus for a sea explorer shown in FIG. In which an underwater probe is connected and towed.

The main traction cable 60 is connected to the front engaging hole 42C of the protruding portion 42B by various connecting means or the like and the rear connecting portion 44 is connected to the underwater probe 10, The front portion 31 of the body 30 is slightly moved forward (in the forward direction) downward by the weight portion 36 while the auxiliary traction cable 70 connected to the auxiliary traction cable 70 is connected by various connecting means, And is pulled in an inclined state.

Therefore, the rising of the body 30 can be suppressed at the time of pulling, the stable traction of the underwater probe 10 can be performed, and stable underwater exploration can be performed.

6, in the state that the underwater probe 10 is pulled by the descending and collecting device for a marine probe according to the present invention in the above-described process, The pulling force of the main traction cable 60 and the pulling force of the underwater obstacle are caught by the front portion 31 of the body 30 when the main pull cable 60 is caught between the front portion 31 and the front connecting portion 42.

When the shaft 41 and the front portion 31 of the body 30 are subjected to an excessive load, an excessive load acts on the sheer pin 50 and the sheer pin 50 is broken.

When the shear pin 50 is broken, as shown in FIG. 7, the body 30 rotates in the direction (forward downward) in which the obstacle underwater is pressed with the shaft 41 as the rotational center, (31).

8, when the shear pin 50 is broken, the body 30 rotates in the direction indicated by the solid line by the load of the underwater obstacle pressing the upper surface of the front portion 31, (31). ≪ / RTI >

With this operation, the descending and collecting device for the ocean probe can be quickly and easily avoided even when it is caught in an underwater obstacle.

At this time, the main traction cable 60 is connected to the projecting portion 42B and the auxiliary traction cable 70 is connected to the "a" -shaped rear connection portion 44 so that the underwater probe 10 is moved downward It is possible to prevent or minimize the interference with the obstacle underwater that deviates from the front portion 31 of the body 30. That is, when the body 30 is rotated by the fracture of the shear pin 50 when the towing frame 40 is "- ", the underwater probe 10 is extended on the extension line of the main tow cable 60, The interference with the underwater obstacle can not be avoided because it is in the interference position of the underwater obstacle.

As described above, when a load value greater than a predetermined load value acts on the body 30 and the front part 31 of the body 30 by interfering with the water, the shear pin 50 is broken and the body 30 Can be easily and quickly dislodged from an underwater obstacle, and the underwater probe 10 can be recovered smoothly.
