Insertion device 26 is configured such that each closure member actuated by a trigger closes the upper and lower ends of the deposit insertion tube, the upper portion of which is selectively closed. Since the structure of the insertion device 26 is known, the detailed description thereof will be omitted.

The lowering delay cylinder 82 penetrates the center of the weight body 22 and the supporter 24, and an upper end thereof is coupled to the bottom of the lower plate 40, and at least one discharge hole 82A is formed in the upper region. . The piston 84 is inserted into the piston 82, the upper end of the rod is coupled to the center of the upper plate 30 as described above. The lowering control unit 80 has a piston due to spaced apart from the upper and lower plates 30 and 40 of the seawater introduced into the lowering delay cylinder 82 when the collecting core 20 sinks into the ocean. 84) is gradually discharged into the discharge hole (82A) by the collecting core 20 is coupled to the falling delay cylinder 82 is operated so as to slowly sink so that disturbance of the deposit does not occur.

Hereinafter, the operation of the present invention will be described.

In the state in which the lowering delay cylinder 82 coupled with the collecting core 20 is coupled to the lower plate 40, and the upper end of the piston 84 is coupled to the upper plate 30, the crane is a vertical member 50. Connected to the upper end of the

This state is a columnar sample collection device is located on the deck of the ship, the seating portion 12 of the guard frame 10 is seated on the deck, the upper plate 30 and the lower plate 40 of the connecting portion 60 Since the state coupled to each other by the safety connecting means, the collecting core 20 is spaced apart from the upper surface of the deck.

That is, as shown in FIGS. 3 and 9, the rotation member 64 is inserted into the locking groove 62A of the latch 62 to maintain the upper plate 30 and the lower plate 40 coupled thereto. Therefore, the deposit insertion tube 25 of the collecting core 20 is to be kept spaced apart from the bottom of the deck.

Subsequently, in order to feed the columnar sample collection device to the seabed using a crane, the vertical member 50 is lifted upward by using a crane, and the handle member 66E of the guy control means 66 as shown in FIG. To move the stopper 66F downward to allow rotation of the pivot member 64. If the rotation of the rotation member 64 is allowed, the rotation member 64 is rotated in the horizontal direction to disengage from the locking groove 62A. Then, the stopper 66F pulled down is released so that the stopper 66F protrudes to the original state, that is, the upper surface of the upper plate 30, thereby preventing the rotation member 64 from being inserted into the locking groove 62A again. . This is to release the locking state of the upper and lower plates 30 and 40 so as to allow separation (separation) from each other.

Subsequently, the guard frame 10 is introduced into the ocean.

The columnar sample collection device introduced into the sea sinks to the bottom of the sea floor by the weight of the guard frame 10 and the weight body 22.

At this time, when the vertical member 50 is lifted by the crane, the lower plate 40 is in close contact with the bottom surface of the upper plate 30, so that the lower plate 40 and the upper plate 30 are firmly formed by the weight of the collecting device. Keep in close contact. That is, even when the rotation member 64 is separated from the locking groove 62A, the upper and lower plates 30 and 40 are not spaced apart.

In this process, when the seating portion 12 of the guard frame 10 is seated on the bottom of the sea floor as shown in FIG. 3, the force that the crane lifts the vertical member 50 is dissipated, and thus the collecting core 20 is self-weighted. Descend by At this time, since the seating portion 12 of the guard frame 10 is first seated on the bottom of the sea floor, the sea bottom region between each seating portion 12 is in a state where disturbance does not occur.

On the other hand, since the rotation member 64 is separated from the locking groove 62A by the above-described process, the coupling of the upper and lower plates 30 and 40 is released, and thus, the collecting corer 20 and the collecting corer ( The lower plate 40 coupled to the 20, the vertical member 50 coupled to the lower plate 40 are all lowered (sinks) by the weight body 22.

At this time, the interior of the falling delay cylinder 82 is moved to the lower in the state filled with the sea water, and the piston 84 coupled to the upper plate 30 is not moving, the falling delay cylinder 82 The seawater inside is gradually discharged through the discharge hole 82A. That is, since about 5-5 mm of discharge holes 82A of about 5-20 mm are drilled so that the seawater inside the lowering delay cylinder 82 is not discharged rapidly, the lowering delay of the lowering cylinder 82 The seawater inside can be discharged slowly.

As described above, since the seawater inside the lowering delay cylinder 82 is gradually discharged through the discharge hole 82A, the sampling corer 20 coupled to the lowering delay cylinder 82 does not suddenly sink, but gradually sinks stably. do.

This is because when the lowering delay cylinder 82 coupled with the harvesting core 20 and the weight body 22 sinks by the weight of the weight body 22 and the harvesting core 20, the seawater therein Since the discharged through the relatively small discharge hole 82A is gradually discharged, the collecting corer 20 sinks in proportion to the speed at which the seawater is discharged without suddenly sinking by its own weight. At this time, the sinking speed of the collecting corer 20 is related to the weight of the collecting corer 20, the weight of the weight body 22 and the like, and the size or number of the discharge holes 82A. That is, the speed of sinking will be slow if the weight is light, the number of the exhaust holes 82A is small or the number is small, and the speed of sinking will be fast if the weight is heavy, the number of the exhaust holes 82A is large or the number is large. . Therefore, it is preferable to control the sinking speed of the collecting corer 20 by setting the weight of the weight body 22, the size and number of the discharge holes 82A, and the like.

When the lower plate 40 moves downward by the above-described process, a stopper 66F installed on the lower plate 40 and protruding to the upper surface of the upper plate 30 is formed in the through hole 32 of the upper plate 30. Since it is detached (falls downward), the rotation member 64 is returned to its original position by the elastic means 65. That is, the rotation member 64 is rotated to its original position by the elastic means 65 and the rotation is stopped by the pawl 62C to maintain its stopped state.

As described above, each seating part 12 of the guard frame 10 is seated on the floor, and the sampling corer 40 is gradually lowered by the lowering control part 80 while the upper plate 30 and the lower plate 40 are spaced apart from each other. Lower deposit tube 25 is inserted into the deposit in a stable state as shown in FIG.

In this process, when the collecting core 40 sinks by a predetermined distance and the deposit insertion tubes 25 are inserted into the deposits, the trigger is activated to close the upper and lower portions of the deposit insertion tubes 25, respectively.

In such a state that the guard frame 10 is stably settled on the bottom of the sea floor, the collecting corer 20 does not sink rapidly by the lowering control unit 80 but stably sinks, so that the sediment is not disturbed. It is possible to collect.

On the other hand, when the deposit is accommodated in the deposit insertion tube 25 by the operation of the trigger, the vertical member 50 is lifted using a crane.

When the vertical member 50 is lifted, the lower plate 40 and the collecting core 20 combined with the vertical member 50 are raised until the lower plate 40 abuts the upper plate 30. .

This process is explained as follows.

As shown in FIG. 7, when the vertical member 50 is lifted by the crane, the lower plate 40 coupled thereto is also raised. At this time, the upper plate 30 coupled to the guard frame 10 is in a stopped state.

Subsequently, as shown in FIG. 8, when the lower plate 40 is raised by the vertical member 50, the rotating member 64 is rotated in the direction of the arrow while contacting the inclined surface 62B of the latch 62. That is, as the latch 62 coupled to the lower plate 40 rises, the rotating member 64 in contact with the inclined surface 62B rotates in the direction of the arrow shown in FIG. 8.

In this process, the stopper 66E is lifted up and inserted into the through hole 32 of the upper plate 30, but since the rotating member 64 is positioned at the top thereof, the stopper 66E comes into contact with the bottom surface of the rotating member 64. The elastic state of the elastic body 66C is overcome, and the stationary state is reached.

And, as shown in FIG. 9, if the pivot member 64A is out of the inclined surface 62B as the latch 62 continues to rise, the pivot member 64 is inclined surface 62B by the elasticity of the elastic means 65. It is rotated in the opposite direction that was rotated by) and is inserted into the locking groove (62A) of the latch (62).

In this process, since the rotation member 64 is inserted into the locking groove 62A of the latch 62, the upper plate 30 and the lower plate 40 are firmly coupled.

In addition, since the upper plate 30 and the lower plate 40 are coupled in the above-described process, the guard frame 10 and the collecting corer 20 are held together by lifting the vertical member 50 by a crane. Will be raised.

Lifting the vertical member 50 by a crane, and then lowered on the deck of the ship or barge, because the guard frame 10 and the harvesting core 20 is coupled by the connecting portion 60 harvesting corer 20 ) Is not in contact with the deck or ground. Therefore, the deposit insertion tube 25 can be protected in a stable state.

As described above, the collecting corer 20 is selectively coupled to the guard frame 10 by the connecting part 60, so that the collecting corer 20 can collect the sediment in a comparative egg state in a stable state. In addition, since the collecting core 20 is gradually settled by the falling control unit 80, the deposit insertion tube 25 is inserted into the deposit without disturbing the deposit, so that the sample such as the deposit can be collected in the comparative egg state. do.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious to those who have. Accordingly, it should be understood that such modifications or alterations should not be understood individually from the technical spirit and viewpoint of the present invention, and that modified embodiments fall within the scope of the claims of the present invention.
