Description

[Detailed Description of the Invention] The present invention relates to a floating wave device with excellent surface wave breaking effects.

Recently, aquaculture fisheries have been forced to develop new fishing grounds because, with the development of near-sea aquaculture, conventional fishing grounds have become unsuitable due to marine pollution.

For aquaculture farms, a place with good seawater displacement by tidal currents and quiet waves is required, but if you go from aquaculture in a bay to the open ocean, the expansion of new fishing grounds is limited because of damage to equipment caused by wind and waves. It is in.

To prevent damage caused by wind and waves, research and development of floating wave devices is progressing, and several types are being tested, but high-performance floating wave devices have not yet been completed. Effectiveness, ease of installation, and low equipment costs are essential conditions, and floating wave devices with a combination of nets and sheets are attracting attention as meeting these conditions.

The present invention improves the conventional floating wave dissipating device to create a wave dissipating device with a high surface wave breaking effect.

That is, the present invention, as shown in the drawings, has a water-permeable network material 1.
This is a floating wave device in which a floating body 5 to which a floating body 3 and a snake cage-like hollow structure 4 are attached is attached to a sheet-like material in which impermeable membrane-like materials 2 are arranged.

Hereinafter, the appropriation, embodiments, and effects of the present invention will be explained in more detail.

In general, the principle of wave dissipation is to break up rotating waves near the sea surface and at the same time break up the energy of surface waves that are created by wind.

Splitting the rotational waves is possible by creating faults using a combination of nets and sheets.

It is possible to break up surface waves by splitting rotating waves, but in order to further increase the effect of this invention, a hollow structure in the shape of a serpentine cage is installed on the sea surface to break up surface waves. By guiding it into the cage and causing the crest of the white waves to break into thousands of pieces inside the cage, it was possible to eliminate the destructive energy.

In the present invention, the sheet-like material is made of synthetic resin, synthetic resin, fiber, or synthetic rubber, and preferably has good water resistance, weather resistance, and corrosion resistance. Specifically, it is made of polyolefin, polyamide, or polyester. synthetic fibers or synthetic resins such as polyvinyl alcohol based, chloroprene rubber, ethylene propyne copolymer, acrylic rubber, inbutylene isoprene rubber, styrene butadiene rubber,
Examples include synthetic rubbers such as nitrile butadiene rubber.

Each of these may be used alone, but if used as a composite of synthetic fiber and synthetic resin or a composite of synthetic fiber and synthetic rubber, improved durability can be expected.

The water-permeable net-like material may be silk fabric or net fabric, and it is preferable from the viewpoint of durability and handling that the thickness of the material constituting the net-like material is about 1 to 1Q mm in diameter.

In addition, the square mesh of the mesh is 5 to 200 mm, preferably 10 to 1
00 mm is necessary from the wave-dissipating effect.

Two or more types of these water-permeable net-like materials having different square mesh may be used in combination.

As the water-impermeable membrane material, high-density fabric, canvas, tarpaulin, synthetic resin sheet, film, etc. are used.

The water-permeable mesh material or the water-impermeable film material can be used individually as a unit, and multiple pieces can be used as a connected body, or the combination of the water-permeable mesh material and the water-impermeable film material can be used as a unit. A plurality of them are used as a connected body.

The water-permeable net-like material 1 and the water-impermeable film-like material 2 are usually regularly and alternately arranged, but the arrangement is not necessarily limited to this.

The size of one unit constituting these connected bodies is 5 to 3 in length.
0 m and a width of 1 to 10 m for handling purposes.

What is important in the present invention is to create a floating body by alternately providing floating bodies and craw cage-like hollow structures at the connecting portions of these connecting bodies.

The floating body may be anything that has sufficient buoyancy to float one unit constituting the connecting body, and for example, a closed foam body such as polyethylene, polypropylene 1, polystyrene, etc., or a floating body made of an impermeable material can be used.

In the present invention, a serpentine cage-like hollow structure is a cage-like structure that has many voids on its surface and is hollow inside. The crest of the white waves is divided into thousands of pieces within the cage, and the destructive energy is extinguished.

Therefore, like a floating body, it is necessary to install it so that it is located on the sea surface, and therefore, the gabion cage-like hollow structure is made to float by filling both ends of the gabion cage with floating bodies similar to the floating body.

The serpentine hollow structure has a circular or polygonal cross-sectional shape, and a diameter of 20 to 200 cyn, preferably 30 cyn.
~100 cm is necessary for the wave-dissipating effect and the stability of the structure.

Note that it is also possible to use a plurality of small diameter ones stacked one on top of the other.

Since the gabion-cage-like hollow structure divides the surface waves into thousands of pieces, the diameter of the gabion cage is suitably about 3 to 30 cm.

When the mesh size is 3 cnn or less, the gabion acts like a breakwater and the surface waves are not divided sufficiently.

Furthermore, when the eyelet is 30 cm or more, the surface waves often pass through the gabion cage, and the separation of the surface waves is still insufficient.

The material constituting the snake cage-like hollow structure includes FRP, synthetic resin, wood, bamboo, metal, etc., but FRP is preferable from the viewpoint of durability.

The length of a floating body having alternating floating bodies and gabion-like hollow structures at the connecting portions varies depending on the installation location of the wave-dissipating device and the purpose of wave-dissipating, but is usually about 10 to 200 m.

In addition, a plurality of such floating bodies are interconnected laterally to form a wave-dissipating device with a width of several tens to hundreds of meters, but the optimum width can be determined depending on the installation location and the purpose of wave dissipation. All you have to do is decide.

Since the floating wave device of the present invention is laid floating on the sea surface, it is usually fixed to an anchor with a tether 6 to prevent it from being deformed or washed away by wind and waves.

The floating wave device of the present invention divides surface waves into thousands of pieces using a gabion-like hollow structure to dissipate their energy, and also dissipates the surface waves by using a water-permeable mesh material, an impermeable membrane material, or a combination thereof. Since it further dissipates wave energy, it has an outstanding wave-dissipating effect and fully fulfills its function as a wave-dissipating device for aquaculture farms.
