Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structure of an anchor for stabilizing a net used for cultivating laver at sea.
[0002]
[Prior art]
Conventionally, glue nets have been used for laver cultivation. FIG. 4 schematically shows a state where the glue net 1 is arranged on the sea surface 2. The ordinary gauze net 1 is formed in a rectangular shape, and a float 3 is attached to a peripheral portion thereof. Therefore, the laver 1 floats on the sea.
An anchor 4 is attached to the periphery of the glue net 1 at several locations. The anchor 4 is connected to the glue net 1 via a rope 5 and is submerged on the seabed 6.
Various anchors for the glue net have been conventionally provided, but there is no literature on the anchor for the glue net known by the applicant at the time of filing the present application.
[0003]
[Problems to be solved by the invention]
By the way, a glue net anchor cannot stabilize a glue net at sea simply by being sunk under the sea floor. This is because there is a flow in the sea, and the sea may be timed depending on the weather, and this may cause the anchor for the glue net to be washed away.
Accordingly, an object of the present invention is to provide a glue net anchor that can reliably stabilize a 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 engaging portion formed in a substantially L-shape continuous with the main portion. A main body formed in a U-shape, a biting portion provided in the tip of the engaging portion, formed in an arrowhead shape, and a piercing rod provided in the biting portion and having a sharp tip. It is characterized by the following.
[0005]
According to this configuration, the anchor for the glue net is submerged on the seabed with a rope or the like connected to the base end of the main part. At this time, the main body 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 contacts the seabed.
A biting portion is formed at the tip of the engaging portion, and the biting portion is formed in an arrowhead shape. Moreover, a piercing rod is provided in this bite portion. Therefore, when the main body reaches the seabed, the piercing rod pierces the seabed, and the bite portion surely digs into the seabed.
[0006]
(2) The piercing bar is preferably arranged outside the bite portion.
In this configuration, when the glue net anchor reaches the seabed, the piercing rod pierces the seabed more reliably.
In addition, it is preferable that the peripheral edge of the tip of the biting portion forms a sharply formed blade.
This configuration has an advantage that the bite portion can bite into the seabed more reliably.
In particular, the bite portion is preferably made of carbon steel having a carbon content of 0.4 to 0.55% by weight.
In this configuration, since the bite portion is made of a very hard material, the bite portion can bite into the seabed more reliably.
[0007]
(3) It is preferable that the main part further includes a tubular member extending in a direction intersecting the longitudinal direction of the main part.
In this configuration, another rod-shaped member can be inserted through the cylindrical member. That is, the tubular member functions as a frame for supporting another rod-shaped member. Thus, the other bar-shaped member forms an arm that projects laterally from the main body. By setting the length of the other rod-shaped member to an appropriate length, the substantially J-shaped main body is prevented from lying on the seabed. That is, it is possible to prevent the piercing portion pierced into the sea floor and the digging portion that digs into the sea bottom from easily coming off the sea floor due to the main body lying down.
[0008]
(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 acts on the main body due to aging of the sea, and as a result, the main body is deformed. This prevents them from easily coming off the seabed.
[0009]
It is preferable that the reinforcing member includes a connecting member that is arranged along a longitudinal direction of the main portion and connects both ends of the main portion. Thereby, the rigidity of the main portion is particularly improved, and the deformation of the main portion is prevented.
Further, it is preferable that the reinforcing member includes a connecting member that connects the main portion and the engaging portion. Thereby, especially the bending rigidity of the engaging portion is improved, and the deformation of the engaging portion is prevented. By preventing the deformation of the engagement portion, the main body is reliably prevented from coming off the seabed.
[0010]
(5) It is preferable that the main body, the bite portion, and the piercing rod are subjected to a rust-proof treatment.
In 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 time.
[0011]

The main part 15 is made of, for example, general structural carbon steel. The one end 17 of the main portion is bent at approximately 90 ° (degree), and the one end 17 is fixed to the engagement portion 16. The fixing of both is realized by, for example, welding. The one side end 17 may of course be formed straight.
[0014]
As shown in FIG. 2, the one end portion 17 is bent and formed to intersect with the main portion 15 at an angle θ1. In the present embodiment, θ1 is set to 92 °. However, the angle θ1 can be appropriately set in a range of 85 ° to 100 °. The function and effect of setting the angle θ1 in such a range will be described later.
Note that a reinforcing pipe 18 is provided to improve the rigidity of the one end portion 17 and suppress a change in the angle θ1. The reinforcing pipe 18 is attached so as to bridge between the one end 17 and the main part 15. The reinforcing pipe 18 is made of, for example, carbon steel for general structure, and is attached by, for example, welding.
[0015]
The other end 19 of the main part 15 is formed in a substantially rectangular plate shape as shown in FIG. In the present embodiment, the other side end 19 is formed by crushing a round pipe constituting the main part 15, but by fixing another plate-shaped member to the main part 15 by welding or the like. It may be configured.
A through hole 20 is provided at the center of the other end 19. The rope or the like is inserted through the through-hole 20, and the anchor 10 is connected to the glue net via the rope or the like.
[0016]
The main part 15 is provided with a connecting member 21 (reinforcing member). In the present embodiment, the connecting member 21 is configured by, for example, a flat bar. The flat bar is made of carbon steel for general structural use. As shown in FIGS. 1 and 2, the connecting member 21 is formed in a substantially rectangular shape, and both ends of the connecting member 21 are respectively connected to both ends of the main portion 15. The center of the connecting member 21 in the thickness direction coincides with the center of the main portion 15. However, there is no particular problem even if the center of the connecting member 21 in the thickness direction does not completely coincide with the center of the main portion 15.
In this embodiment, the connecting member 21 is formed in a substantially rectangular shape by a flat bar, but it is a matter of course that the present invention is not limited to this shape. In short, as long as the rigidity of the main portion 15 can be improved, other shapes and materials can be adopted for the connecting member 21.
[0017]
The engaging portion 16 is formed in a substantially L shape. In the present embodiment, the engagement portion 16 is configured by, for example, bending a flat bar into a substantially L-shape. The flat bar is made of carbon steel for general structure.
As shown in FIG. 2, the bending angle θ2 is set to 110 ° in the present embodiment. However, the bending angle θ2 can be appropriately set in a range of 90 ° to 130 °. The function and effect of setting the bending angle θ2 in such a range will be described later.
The base end portion 22 of the engaging portion 16 is fixed to the one end portion 17 of the main portion 15, and the fixing means employs welding as described above.
By attaching the engaging portion 16 to the main portion 15 in this manner, the main body 11 is formed in a substantially J shape.
[0018]
The biting portion 12 is provided at the tip of the engaging portion 16. The engagement portion 16 and the bite portion 12 are fixed by, for example, welding. In the present embodiment, the bite portion 12 is formed of a flat bar, and the flat bar is formed of general structural carbon steel. It is needless to say that the biting portion 12 may be formed integrally with the engaging portion 16.
In the present embodiment, the bite portion 12 is made of high carbon steel. Specifically, the bite section 12 is configured by S45C. However, the material forming the bite portion 12 is not limited to this, and carbon steel having a carbon content of 0.4% by weight to 0.55% by weight may be employed.
[0019]
In addition, the tip of the biting portion 12 is sharply formed in a triangular shape as shown in FIG. In addition, the peripheral edge portion of the bite portion 12 is cut off the meat, thereby forming the blade 23. Therefore, the tip portion of the biting portion 12 is extremely sharply finished.
The function and effect of the bite portion 12 formed in such a shape will be described later.
[0020]
The piercing rod 13 is provided outside the biting portion 12. Specifically, the piercing rod 13 is fixed to the bite portion 12 by, for example, welding.
In the present embodiment, the piercing bar 13 is a round bar made of carbon steel for general structure. However, the distal end portion 24 of the piercing rod 13 is gradually reduced in diameter as shown in FIG. 1, and is formed in an extremely sharp shape.
The function and effect of the thrust bar 13 formed in such a shape and the function and effect of the thrust bar 13 provided outside the bite portion 12 will be described later.
[0021]
In the present embodiment, a connecting member 25 (reinforcing member) is further provided. In the present embodiment, the connecting member 25 is formed of, for example, a flat bar, like the connecting member 21. The flat bar is made of carbon steel for general structural use. As shown in FIG. 1, the connecting member 25 is a straight member, and both ends thereof are connected to the intermediate portion of the main portion 15 and the bite portion 12, respectively. The connecting member 25 is fixed to the main portion 15 and the bite portion 12 by, for example, welding.
[0022]
As shown in FIGS. 1 and 3, the connecting member 25 is disposed so as to overlap the connecting member 21, and the connecting member 21 and the connecting member 25 are fixed by, for example, welding.
Although the connecting member 25 is formed of a flat bar in the present embodiment, a member other than the flat bar may be employed. In short, the coupling member 25 can adopt another shape and material as long as the coupling between the main portion 15 and the engagement portion 16 and the rigidity of the main body 11 can be improved.
[0023]
The support frame 14 is formed of a cylindrical member. In the present embodiment, the support frame 14 is made of stainless steel, but may be made of general structural carbon steel.
The support frame 14 is fixed to the main part 15 via a seat plate 26. The seat plate 26 is a plate-shaped member made of carbon steel for general structure, and is disposed between the main portion 15 and the connecting members 21 and 25. The seat plate 26 is fixed to the main portion 15 and the connecting members 21 and 25 by, for example, welding. The seat plate 26 is provided with a through hole, and the support frame 14 is inserted and fixed in the through hole. As the fixing means, for example, welding or the like is employed.
It should be noted that the shape of the seat plate 26 is not particularly limited, and other shapes may be adopted as long as the support frame 14 can be held and fixed.
[0024]
This anchor 10 is used as follows.
First, for example, one end of a rope is connected to the through-hole 20 (the through-hole 20 formed at the end of the main portion 15) of the anchor 10, and the other end of the rope is connected to a predetermined portion of the glue net. . If necessary, the bar-shaped member 27 constituting an arm is inserted into the support frame 14 and fixed. In this state, the anchor 10 is submerged in the sea.
[0025]
At this time, the main body 11 is formed in a substantially J-shape, and the anchor 10 descends in the sea with the engaging portion 16 preceding. Therefore, when the main body 11 reaches the seabed, the engaging portion 16 comes into contact with the seabed.
A biting portion 12 is formed at the tip of the engaging portion 16, and since the biting portion 12 is formed in an arrowhead shape, the biting portion 12 easily bites into the seabed. Further, since the piercing bar 13 is provided in the biting portion 12, the piercing bar 13 also pierces the seabed.
[0026]
Therefore, when the anchor 10 is inserted into the sea and the main body 11 reaches the seabed, the piercing rod 13 pierces the seabed, and the bite portion 12 bites into the seabed, so that the anchor 10 is securely fixed to the seabed. You. As a result, the glue net is reliably and stably fixed on the sea surface by the anchor 10 without the glue net being washed away due to the ocean current, sea weathering, or the like.
[0027]
In particular, in the present embodiment, a blade is formed at the peripheral edge of the tip end of the bite portion 12. Thereby, when the main body 11 reaches the seabed, the biting portion 12 can more easily and surely cut into the seabed. Therefore, the anchor 10 is more securely fixed to the seabed, and as a result, the glue net is more reliably and stably fixed at the sea surface.
Further, since the bite portion 12 is made of high carbon steel such as S45C, the bite portion 12 is made of a very hard material. Therefore, there is an advantage that the bite portion 12 can bite into the seabed more reliably.
[0028]
Moreover, since the tip portion 24 of the piercing rod 13 is formed particularly sharp, the piercing portion 13 can surely dig into the sea floor.
In addition, since the piercing rod 13 is provided outside the digging portion 12, when the anchor 10 reaches the seabed, first, the piercing rod 13 pierces the seabed surely, and then the digging portion 12 also moves to the seabed. Is surely pierced. Thereby, there is an advantage that the anchor 10 can reliably engage with the seabed regardless of the state of the seabed.
[0029]
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 this case, since the piercing rod 13 is also made of a very hard material, there is an advantage that the piercing rod 13 can bite into the seabed more reliably.
[0030]
Further, when the rod-shaped member 27 is fixed to the support frame 14 as in the present embodiment, the rod-shaped member 27 forms an arm that projects laterally from the main body 11 on the sea floor. The length of the rod-shaped member 27 is set to 2 m to 3 m (2750 mm in the present embodiment), which prevents the main body 11 from lying on the seabed.
That is, it is possible to prevent the piercing rod 13 pierced into the seabed and the biting portion 12 digging into the seabed from easily coming off the seabed. Therefore, the glue net is more reliably and stably fixed on the sea surface by the anchor 10.
[0031]
Further, in the present embodiment, a reinforcing member for improving the rigidity of the main body 11 is provided. Thereby, 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, aging of the sea. As a result, it is reliably prevented that the anchor 10 easily comes off the seabed due to the deformation of the main body 11.
Specifically, the rigidity of the main portion 15 of the main body 11 is improved by the connecting member 21, while the bending rigidity of the engaging portion 16 is improved by the connecting member 25. Thereby, the deformation of the main portion 15 and the deformation of the engaging portion 16 are suppressed, so that the anchor 10 does not easily come off the seabed.
[0032]
In addition, in this embodiment, the anchor 10 is not subjected to a surface treatment or the like, but the entire anchor 10 may be subjected to a rust prevention treatment. Specifically, zinc plating or the like may be applied to the main body 11, the bite portion 12, the piercing rod 13, and the connecting members 21, 25, and the like. Further, 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 time.
[0033]
【The invention's effect】
As described above, according to the present invention, the distal end portion of the anchor for a glue net surely bites into the seabed and is locked to the seabed, so that the anchor for the glue net is securely fixed to the seabed. Accordingly, the glue net is reliably and stably fixed on the sea surface by the glue net anchor.
