Description

[Detailed Description of the Invention] The present invention relates to a locking device for aquaculture, which is used to lock cultured marine products such as scallops and oysters to hanging ropes in the sea.

Conventionally, when cultivating scallops and oysters artificially, a method has been adopted in which the scallops are placed in a culture cage or net and placed in the sea for a predetermined culture period. However, with this type of cage/net method, if the cultivation period is prolonged, various kinds of seaweed etc. will adhere to the holes of the cage/net, and fresh tidal water, which provides the oxygen necessary for the growth of the oysters, will be absorbed. This can stop the flow, easily inhibiting growth, and in severe cases can cause damage such as large numbers of molluscs dying.

Therefore, many thin hanging ropes are hung at regular intervals from a girder rope stretched horizontally on the sea surface or in the sea, and small holes are made in the ears of scallops etc. using extremely thin fishing line hooks, etc. One possible method is to drill a hole, thread the rope through it, insert it between the strands of the hanging rope, and tie it by hand. Although this method significantly reduces material costs, the labor costs associated with hand-tying increase and mechanization becomes difficult, resulting in the problem that overall cost reductions are not necessarily achieved.

In view of this, the present invention has a locking part that locks on the hanging rope and a locking part that locks on the ears of the shellfish at both ends, in order to significantly reduce the number of work hours associated with conventional hand tying. The main purpose is to propose a locking device.

An embodiment of the present invention will be described in detail below with reference to the drawings.

1 and 2 are a plan view and a front view showing an example of the fastening device of the present invention. 1 is a rope locking part 1a with a diameter of 1 to 3 mm, which is inserted and locked between the strands of a hanging rope, and a cultured product locking part with a diameter of about 0.5 to 1.2 mm, which is inserted and locked in the ear of a mollusc. 1b
indicates a locking device provided at the other end. The rope locking portion 1a and the cultured product locking portion 1b of the locking device 1 are connected to the base 1c.
It is integrally molded from flexible synthetic resin so that it has a T-shape at both ends. Furthermore, a stopper part 1d having an acute angle at the tip is integrally formed and extends from the contact point between the rope locking part 1a and the base part 1c at an angle of 45 degrees toward the base part 1c. The stopper portion 1d is at an angle of 90° to the rope locking portion 1a. As shown in FIG. 3, the cultured product locking part 1b is
By making the diameter of the insertion side 1e, which is inserted into the hole 2a bored in the ear part of the shell 2, smaller than that of the other side 1f,
It is made easy to deform so that it becomes almost parallel to the base 1c. The tip of the insertion side 1e may be formed into a sharp shape to further facilitate insertion. By making the length of the rope locking part 1a the same on the left and right sides around the base 1c, and making it smaller than the diameter of the hanging rope and larger than the diameter of the strand, there is no possibility that the locking tool 1 will come off from the rope over a long period of time. That will disappear.

FIG. 4 is a diagram showing the state in which the present fastening tool is used. The hanging ropes 7 hanging from the girder ropes 6 at regular intervals are partially untwisted at intervals where the slugs 8 do not come into contact with each other to create gaps, and the locking tools 1 are inserted into these gaps.
Insert the rope locking part 1a. In this case, a space may be secured according to the length of the rope locking portion 1a. When the strand is returned to its original state, the stopper part 1d bites into the strand 7a, which eliminates the problem of the locking tool shifting downwards due to loosening of the strand due to long-term use, and the problem of collecting shells at the bottom. . The insertion side 1e of the cultured product locking part 1b has a small diameter and its strength is weak, and there is a risk of cutting as the weight increases due to the growth of the shellfish, but in reality, the hole 8a becomes calcareous as the shellfish grows. to be repaired,
Since the cultured product locking portion 1b and the ear of the shellfish are firmly held, the practical effect is not impaired simply because the cultured product locking portion 1b is thin.

As described above, according to the present invention, in a flexible locking device in which a rope locking portion and a cultured product locking portion are integrally molded in a T-shape at both ends of the base, the base and the rope locking portion are integrally formed. Since the stopper part having an acute angle at the tip is integrally molded with the locking tool from the contact point to the base side, there is no need to tie the hanging rope together with a trapezoid, etc., as in the past. It is sufficient to simply insert it into the hole in the ear of the hanging rope or the selvedge, which not only improves the efficiency of manual work without relying on mechanization, but also prevents the proposed locking device from lowering against the hanging rope after long-term use. It can prevent it from shifting to the side, and it prevents molluscs and the like from accumulating in one place at the bottom and inhibiting their growth. Moreover, compared to the conventional cage/net method, this method has the effect of promoting the growth of aquaculture products through direct contact with the tidal current.
