Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to floating reefs arranged from the middle layer to the surface layer in the sea.

[0002]

2. Description of the Related Art Conventionally, floating floating reefs include, for example, surface-type floating fishing reefs that are placed on the sea surface such as dolphin pickles and bonito pickles, and middle-layer floating fishing reefs that are placed in the sea 5 to 40 meters below the sea level.

[0003]

[Problems to be Solved by the Invention] In the surface type floating reef, it is easy to confirm the position because it floats on the surface of the sea, and fishing lines and drift nets are less likely to be caught, and it is advantageous in that it can be manufactured at low cost and has a large gathering effect. However, since it is strongly affected by the wave force, the mooring line is repeatedly subjected to excessive tension and is easily broken, and the service life is short at about one year.

[0004] In the middle layer type floating fishing reef, there is an advantage that the mooring line is hardly affected by the wave force and the tension applied to the mooring line is almost constant, so that the mooring line is hard to break, has excellent durability and has a large gathering effect. However, there is a risk that it will not be directly visible from the sea and that fishing lines and drift nets may be caught. To prevent this accident, for example, the so-called "mountain deck" that looks through two targets.
Although the position is confirmed by this, there is a drawback that it is easy to misidentify the position, and it is also possible to confirm the position by receiving a signal by attaching a radio transmitter such as an underwater pinger. Then, there is a drawback that the production cost is high.

In view of the above drawbacks, it is an object of the present invention to provide a floating reef where the position can be easily confirmed, mooring can be reliably carried out, and the collecting effect is great.

[0006]

In order to achieve the above-mentioned object, the present invention is to provide a middle-layer fishing reef main body placed in the sea by mooring to the seabed via a mooring line, and a mooring line for the middle-layer fishing reef main body. A main surface of the reef main body that is placed on the sea surface by being connected via the main body, and a horizontal stabilizer that is provided at the lower part of the main part of the main surface reef or the upper part of the main part of the middle reef and suppresses vertical movement of the main part of the main surface reef. It is characterized by being.

[0007]

[Advantageous Effects] According to the above configuration, a large fishing reef is formed from the surface submarine to the middle sublayer by the main surface reef main body and the middle layer reef main body, so that various fish swimming in the subsurface surface layer and the middle layer can be effectively collected. it can. In addition, since the surface reef main body can be directly visually inspected, the position can be easily confirmed and there is little possibility of being caught by a fishing line or a drift net. Furthermore,
The horizontal stabilizer suppresses the vertical movement of the surface reef body and prevents the mooring lines from being subjected to excessive tension. Therefore, both reef bodies can be moored reliably and the durability is excellent.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the present invention, which is a mid-layer fish reef main body 1 arranged in the sea 5 to 40 m below the sea level,
A surface fishing reef main body 2 arranged on the sea surface and a horizontal stabilizer 3 are provided.

The middle-layer fishing reef main body 1 has a length of 5 formed by closing the upper and lower openings of an iron pipe filled with a foamed synthetic resin such as urethane or a synthetic resin pipe made of vinyl chloride with a lid, for example. It is a bundle of a plurality of floating bodies 4 having a length of about 10 m, has a buoyancy force that does not sink by a tidal current, and is moored to a concrete sinker 6 on the seabed via a mooring line 5 made of a synthetic fiber rope or the like.

The lower end of the mooring line 5 is connected to a connecting member 7 formed of an old tire or an iron ring protruding from the sinker 6, and the upper end of the connecting metal fitting 8 is formed of a shackle or the like.
It is connected to the lower end portion of the middle layer reef main body 1 via. An anchor may be used instead of the sinker 6.

The surface fishing reef main body 2 has a spherical floating body 9 having substantially the same structure as the floating body 4 of the middle fishing reef main body 1, a tower-shaped rod 10 standing on the floating body 9, and attached to the upper end of the rod 10. And a position confirming flag 11 and are moored to the middle layer reef body 1 via mooring lines 12.

The mooring line 12 may be a synthetic fiber rope, but as shown in the figure, it is preferable to use a chain. This can prevent the mooring line 12 from being cut by the fishing line or the drift net. Further, the buoyancy of the floating body 9 is slightly larger than the weight of the surface reef body 2 and the mooring line 12, and the preliminary buoyancy is small so that the mooring line 12 is not subjected to excessive tension.

The horizontal stabilizer 3 is made of a polygonal or circular steel plate having a diameter larger than those of the two reef main bodies 1 and 2, and is fixed to the upper surface of the middle-layer reef main body 1 to move the surface reef main body 2 up and down. The mooring line 12 is restrained so that excessive tension is not applied.

According to the above construction, a large fishing reef is formed from the surface layer to the middle layer in the sea by the surface layer 2 and the middle layer 1 so that various kinds of fish swimming in the surface layer and the middle layer can be effectively collected. be able to. Further, since the surface fishing reef main body 2 can be directly visually inspected, the position can be easily confirmed and there is little possibility that fishing line, drift net or the like will be caught. Furthermore, since the horizontal stabilizer 3 suppresses the vertical movement of the surface layer reef main body 2 so as not to apply excessive tension to the mooring line 12, both the reef main bodies 1 and 2 can be reliably moored, and the durability is improved. Is excellent.

FIG. 2 shows another embodiment of the present invention, which has almost the same structure as the floating fishing reef of the above-mentioned embodiment, but is different in the following points. That is, the floating body 9 of the main surface reef body 2 is composed of a plurality of pipe-shaped portions 9a and a cylindrical portion 9b, and a position confirming lamp 13 is provided on the upper end of the rod-shaped rod 10. In addition, the horizontal stabilizer 3 is formed in a downward umbrella shape and is fixed to the lower end portion of the surface fishing reef main body 2, and mooring lines are attached to the lower surface center portion of the horizontal stabilizer 3 via a connecting metal fitting 14 such as a shackle. The upper ends of 12 are connected.

According to the above construction, the surface reef body 2 is of a vertical type and is not easily affected by wave forces, the vertical length of the floating body 9 is 5 to 15 m, and the mooring line 12 is deep below the sea level. Since the fishing line, the drift net, etc. are not easily caught, the synthetic fiber rope, which has less strength than the chain but is less likely to be corroded, can be used as the mooring line 12.

In both of the above embodiments, the floating bodies 4, 9, are
It was made of steel or synthetic resin pipes or spheres filled with foamed synthetic resin such as urethane, but instead of this,
As shown in FIGS. 3A and 3B, an inner cylinder 15 made of synthetic rubber or the like having elasticity and airtightness, and a high tensile strength such as a three-layer aramid fiber arranged on the surface of the inner cylinder 15. An outer cylinder 16 made of strong fibers and a plurality of hermetically sealed bags 18 composed of pressing fiber materials 17 arranged on the surface of the outer cylinder 16 may be arranged at a predetermined interval. Reference numeral 19 is an air inlet with an opening / closing valve 20.

According to this structure, since it is lightweight, it is easy to carry and assemble. Also, because the buoyancy is large,
The diameter of the sealing bag 18 can be reduced, and it is less likely to be affected by wave force.
Further, it has great strength against external forces such as tension, compression, bending, shearing and twisting, does not rust, and is excellent in durability.
