Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating reef, particularly a floating reef installed at a predetermined depth suitable for gathering required fish regardless of the depth.

[0002]

2. Description of the Related Art Conventionally, floating fish reefs having a large stimulating area by combining a plurality of bin balls or attaching a fish net around a floating body have been devised and used in order to gather fish migrating on the surface layer and the middle layer. .

[0003]

[Problems to be Solved by the Invention] However, such a normal floating reef simply forms a shadow of a certain area in the sea and causes the migrating fish to gather in such a shadow, resulting in poor gathering efficiency. And other problems.

Accordingly, an object of the present invention is to solve such a problem, not only to have a simple structure and to simply form a shadow in the sea, but also to facilitate upwelling by a cylinder attached to a floating body. in Construction to providing a high payaos practical effects can be enhanced fish swarm efficiency of the surface layer and the intermediate layer in.

[0005]

[MEANS FOR SOLVING THE PROBLEMS] To achieve the above object
, This invention is directed elongated floating in water depth direction, in payaos <br/> Ru consists of at least one elongated cylinder mounted around the floating body, a certain direction floating body with respect to tidal mounted Rutotomoni the vertical stabilizer wing on the floating body, cylindrical as
Is formed with the lower end opening slightly oblique .

[0006]

According to the present invention , the lower end of a cylinder mounted around a floating body whose direction is kept constant by vertical stabilizers.
Since the opening is formed slightly diagonally,
The tidal current is easy to flow in, and the inflowing tidal current rises inside the cylinder and flows out of the upper end opening to create an upwelling flow at the top of the cylinder, so that the seawater is well mixed and the lower plankton moves upward This has the effect of further increasing the concentration of fish carried.

[0007] Other objects, features and advantages of the present invention will become more readily apparent from the following detailed description taken in conjunction with the accompanying drawings.

[0008]

EXAMPLES As shown in FIGS. 1 to 3, fruit of this invention
Payaos 1 is施例 comprises an elongated floating body 2 in the depth direction, this
With three elongated cylindrical 3 mounted around the floating body floating body 2 is mainly composed of vertical stabilizer blades 6 for attached to the floating body 2 to face a certain direction with respect to the tide, the floating body 2 An anchor 5 is attached to the end of the mooring line 4 attached to the lower end, and is fixed at a required depth to the seabed. Floating body 2
Is made of an appropriate material such as plastic or metal so as to have a required buoyancy. For example , a hollow cylindrical shape is preferable as shown in the figure. An attachment 9 for attaching the mooring line 4 is provided at a lower end of the cable 2. Mounted around the floating body 2
Cylinder 3 is made elongated plastic tube or metal tube, the lower end opening is slightly obliquely with memorial slight angle α
Is formed. In the illustrated embodiment the three cylindrical 3, mounted around the floating body 2 by steel fixing band 7, der which achieves the desired effect even one cylinder 3
You. Further, a plurality of cylindrical 3, for example, when Keru mounted as illustrated in the embodiment, it is preferable to provide a stiffener 8 to maintain a gap between the cylinder 3. Such a floating fish reef 1
The length of the floating body 2 and the cylinder 3 is preferably about 1/10 of the water depth. In addition, the lower end opening of the cylinder 3 is formed slightly oblique.
The cutting angle α for about 5 ° position is preferred.

Such a floating reef 1 is mounted on the seabed with a required length of the mooring line by attaching one end of the mooring line 4 to the mounting 9 at the lower end of the floating body 2 and the other end to the anchor 5. For example, a required shadow is formed by the floating reef 1 and the floating body 2 and the cylinder 3 are maintained in a certain direction with respect to the tide by the vertical stabilizing wings 6 attached to the lower part of the floating body 2.
Easily flow into the power flow from the opening in the cylindrical 3 by oblique lower end opening of the cylinder 3 is slightly angular attached faces the fixed direction with respect to trends, the upper end this trend is upward in the cylinder 3 Since it flows out of the opening, the hollow cylinder 3
A large upwelling is formed above the sea, the seawater is mixed well, and the plankton below the sea is blown up above the floating fish reef 1, so that the aggregation efficiency of fish is further increased and the vertical stabilizing wing 6 constantly floats. Since the reef 1 is oriented in a certain direction and does not rotate, the mooring line 4 is not damaged,
The entire floating reef can be manufactured at low cost and with a simple structure.

[0010]

According to the invention, the opening at the lower end of the cylinder is reduced.
It is a simple structure that is formed diagonally.
The tidal current is easy to flow in, and the flowing tidal current rises in the cylinder
Upwelling flows out of the upper end of the cylinder by flowing out of the top opening
The seawater is well mixed by this
Plankton is carried upwards to further increase fish aggregation
This has a tremendous effect.
