[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anchor structure for stabilizing a net used for aquaculture of seaweed at sea.

[0002]

2. Description of the Related Art Glue nets have been used for the cultivation of seaweed. FIG. 4 schematically shows a state in which the glue net 1 is arranged on the sea surface 2. The ordinary mesh 1 is formed in a rectangular shape, and the float 3 is attached to the peripheral portion thereof. For this reason, the seaweed knitting 1 floats on the sea. Anchors 4 are attached to the periphery of the glue net 1 at several places. This anchor 4 is connected to the glue net 1 via a rope 5.
And is sunk on the seabed 6. Although various anchors for glue nets have been conventionally provided, there is no document about the anchors for glue nets known to the applicant at the time of filing this application.

[0003]

By the way, the glue net anchor cannot stabilize the glue net at sea simply by being submerged in the seabed. Because in the sea,
This is because there is a flow and the sea may be stormy depending on the weather, which may cause the glue net anchor to be washed away. Therefore, an object of the present invention is to provide a glue net anchor that can reliably stabilize the glue net at sea.

[0004]

[Means for Solving the Problems] (1) In order to achieve the above object, a glue net anchor according to the present application has a substantially straight main portion and an engagement formed in a substantially L-shape continuous to the main portion. Body, which is formed in a substantially J-shape as a whole, and is provided at the tip of the engaging portion, and is formed into a barbecue. And a formed piercing rod.

According to this structure, the glue net anchor is
It is sunk on the seabed with a rope connected to the base end of the main part. At this time, the body, which is formed in a substantially J-shape, descends in the sea with its leading end, that is, the engaging portion preceding. Therefore, when the main body reaches the seabed, the engaging portion abuts on the seabed. A biting part is formed at the tip of the engaging part, and the biting part is formed in a hook shape. Moreover, a piercing bar is provided in this bite portion. Therefore, when the main body reaches the seabed, the piercing bar sticks into the seabed and the biting part surely bites into the seabed.

(2) It is preferable that the piercing rod is arranged outside the biting portion. With this configuration, when the glue net anchor reaches the seabed, the piercing bar more reliably pierces the seabed. Further, it is preferable that the peripheral edge portion of the tip of the biting portion constitutes a sharply formed blade. This configuration has an advantage that the biting part can bite into the seabed more reliably. In particular, it is preferable that the biting portion is made of carbon steel having a carbon content of 0.4 to 0.55% by weight. In this configuration, the bite portion is made of a very hard material, and therefore the bite portion can bite into the seabed more reliably.

(3) It is preferable that the main portion further includes a tubular member extending in a direction intersecting the longitudinal direction of the main portion. In this configuration, another rod-shaped member can be inserted into the tubular member. That is, the tubular member functions as a frame for supporting another rod-shaped member. This allows
The other rod-shaped member constitutes an arm protruding laterally from the main body. Then, by setting the length of the other rod-shaped member to an appropriate length, it is possible to prevent the main body formed in the substantially J shape from lying on the seabed. That is, it is possible to prevent the pierced portion pierced into the seabed and the bite portion that digs into the seabed from easily coming off the seabed due to the body lying down.

(4) It is preferable that a reinforcing member for improving the rigidity of the main body is further provided. In this configuration, since the rigidity of the main body is improved by the reinforcing member, the main body is prevented from being deformed even when an external force is applied to the main body due to aging of the sea, and as a result, the main body is deformed. This prevents it from coming off the seabed easily.

It is preferable that the reinforcing member includes a connecting member arranged along the longitudinal direction of the main portion and connecting both end portions of the main portion. As a result, the rigidity of the main portion is improved, and the deformation of the main portion is prevented. Furthermore, it is preferable that the reinforcing member includes a connecting member that connects the main portion and the engaging portion. Thereby, the bending rigidity of the engaging portion is improved, and the deformation of the engaging portion is prevented. By preventing the deformation of the engaging portion, the main body is reliably prevented from coming off the seabed.

(5) It is preferable that the main body, the biting portion, and the piercing rod are subjected to anticorrosion treatment. With this configuration, the main body, the biting portion, and the piercing rod do not rust, and the performance of the glue net anchor is maintained for a long period of time.

Is surely pierced into the seabed, and then the biting part 12 is also reliably pierced into the seabed. This has the advantage that the anchor 10 can be reliably engaged with the seabed regardless of the state of the seabed.

The piercing rod 13 may also be made of high carbon steel (carbon steel having a carbon content of 0.4 to 0.55% by weight). In that case, since the piercing bar 13 is also made of a very hard material, the piercing bar 13
Has an advantage that it can more certainly penetrate into the seabed.

When the rod-shaped member 27 is fixed to the support frame 14 as in the present embodiment, the rod-shaped member 27 constitutes an arm protruding laterally from the main body 11 on the seabed. The length of the rod-shaped member 27 is set to 2 to 3 m (2750 mm in this embodiment), which prevents the main body 11 from lying down on the seabed. That is, the piercing stick 13 pierced on the seabed
Also, it is possible to prevent the biting part 12 that has digged into the seabed from easily coming off the seabed. Therefore, the glue net is
The anchor 10 ensures more stable and stable fixing on the sea surface.

Further, in this embodiment, a reinforcing member for improving the rigidity of the main body 11 is provided. As a result, the rigidity of the main body 11 is improved, so that the main body 11 is prevented from being deformed even when an external force acts on the main body 11 due to, for example, sea storms. As a result, the main body 1
It is reliably prevented that the anchor 10 easily comes off the seabed due to the deformation of the anchor 1. In particular,
The connecting member 21 improves the rigidity of the main portion 15 of the main body 11, while the connecting member 25 improves the bending rigidity of the engaging portion 16. Thereby, the deformation of the main portion 15 and the engaging portion 1
Since the deformation of 6 is suppressed, the anchor 10 does not easily come off the seabed.

In addition, in this embodiment, the anchor 10 is not subjected to surface treatment or the like, but the entire anchor 10 may be subjected to rust prevention treatment. Specifically, the main body 11,
The biting part 12, the piercing bar 13, the connecting members 21, 25, etc. may be galvanized. All members may be made of stainless steel or the like. This prevents the anchor 10 from rusting, and the anchor 10 can be used for a long period of time.
