The weighing structure 110 may be formed of a concrete structure or a metal structure so as to increase the weight of the float 100 while lowering the center of gravity of the float 100 and the aqueduct structure 300, The float 100 and the aquarie structure 300 can maintain the wind turbine generator 200 in a stable floating state in a certain positional area of the sea even if no additional mooring device is installed.

The wind turbine generator 200 is connected to an upper end of the float 100 and generates electric power using the wind generated from the sea. The wind turbine generator 200 is connected to the upper end of the float 100 so as to be extended to the upper portion of the float 100. The wind turbine generator 200 includes a tower 210 coupled to an upper end of the float 100 and a turbine 210 connected to an upper end of the tower 210 to generate electricity from the rotational force of the blade 230.

In this way, when the lower end of the wind power generator 200 is rotatably connected to the upper end of the float 100, when a wind force of a predetermined intensity or more is generated, all the forces are transmitted to the float 100 and the aquarium structure 300 Thereby preventing the float 100 and the aquarie structure 300 from stably supporting the wind power generator 200. In addition,

The aquarium structure 300 together with the float 100 provides buoyancy to support the wind power generator 200 in a floating state from the sea and provides a space for living fish or shellfish It is a structure. The diaphragm structure 300 may have a tubular shape to provide the space, and may be formed to be open to the inside or outside to allow the fish to enter and exit. Here, the diaphragm structure 300 supports the wind power generator 200 together with the float 100, and the lower end portion of the diaphragm structure 300 is in a state of being immersed in water to form fish or shellfish So that the buoyancy can be floated.

Here, the diaphragm structure 300 is connected to the float 100, more preferably, connected to the float 100 in a state of being inserted outside the float 100. In this way, only the lower end portion of the diaphragm structure 300 is placed in the water immersed state, and the upper end portion of the diaphragm structure 300 is protruded out of the water surface, so that the space of the diaphragm structure 300 is filled with the plankton The growth of fishes and shellfishes can be stabilized and the fishes and shellfishes can be treated in the excrement.

The diaphragm structure 300 may include upper and lower ring members 310, a vertical connecting bar member 320, and a horizontal fixing bar member 330. The upper and lower ring members 310 are circular ring-shaped members arranged so as to be inserted outside the float 100, and a plurality of the upper and lower ring members 310 are arranged so as to be spaced apart from each other in the vertical direction. The size of the space portion in which the fish can live is determined according to the diameter and the spacing distance of the upper and lower ring members 310. Here, the upper and lower ring members 310 are arranged so as to face each other on the upper side and the lower side. However, the diameter of the upper and the lower ring members 310 may be different from each other, Of course, be formed differently. The vertical connecting bar member 320 is a bar member connecting the plurality of upper and lower ring members 310. One end of the vertical connecting bar member 320 is connected to the upper and lower ring members 310 disposed at the upper side and the other end of the vertical connecting bar member 320 is disposed at the lower side of the upper and lower ring members 320, (310). Here, the vertical connecting bar member 320 connects a plurality of the upper and lower ring members 310 so that the plurality of upper and lower ring members 310 can be stably coupled to each other. The horizontal fixing bar member 330 is a bar member for connecting the plurality of upper and lower ring members 310 to the float 100, respectively. One end in the longitudinal direction of the horizontal fixing bar member 330 is connected to the float 100 and the other end in the longitudinal direction of the horizontal fixing bar member 330 is connected to the inner peripheral surface of the upper and lower ring member 310 . The horizontal fixing bar member 330 includes a plurality of vertical locking bar members 330 so that the upper and lower ring members 310 can be stably fixed to the float 100. In this case, May be coupled to the upper and lower ring members 310 in a radial manner about the float 100. Here, a position control unit 500 to be described later is connected to the upper and lower ring members 310 positioned in contact with the water surface.

In this way, the diaphragm structure 300 has a cylindrical structure and is connected to the outside of the float 100 in an inserted state, and the float 100 maintains a stable equilibrium state in a locked state, So that it can float in a state where it does not deviate to a certain position in the sea even without an additional mooring device.

The aquarium 400 is connected to the aquarie structure 300 in a state where the aquarium structure 300 is wrapped so that the fish or the shellfish can be enclosed in a space of the aquarium structure 300. That is, the style network 400 prevents a fish or a shellfish having a predetermined size or more from entering or exiting the outside of the style structure 300 in the space portion of the style structure 300. The style network 400 may be installed by adjusting the net size according to the size of the fish or shellfish to be cultured. Here, the style network 400 is shown to surround the entire cylindrical structure 300, but the present invention is not limited thereto, and it is also possible to enclose only the lower end portion of the style structure 300 that is locked in the water .

The balancer 500 absorbs the wave motion energy transmitted to the aquarie structure 300 so that the aquarium structure 300 and the float 100 maintain a stable equilibrium state in the sea Let's do it. More specifically, the equilibrium holding unit 500 generates kinetic energy while rotating by the wave motion energy of the sea, absorbs the wave kinetic energy, So that it is possible to maintain a stable equilibrium position in the sea. In order to stably absorb the wave kinetic energy generated in the sea, the plurality of equilibrium holders 500 are spaced from each other along the outer circumference of the aquarium structure 300, (300). 2, the balance holding unit 500 includes a support frame 510, an absorption plate 520, and an elastic connecting member 530.

The support frame 510 is a frame fixedly coupled to the diaphragm structure 300, and rotatably supports the absorption plate 520. Here, the support frame 510 includes a pair of horizontal bar members 511 disposed to face each other in a spaced-apart relationship, a pair of vertical bar members 511, Member 512 having a rectangular ring shape. The support frame 510 is fixedly coupled to the upper and lower ring members 310 of the diaphragm structure 300 contacting the water surface of the diaphragm structure 300.

The absorbing plate 520 is rotatably hinged to the longitudinal bar member 512 in a state where the absorbing plate 520 is disposed inside the support frame 510, more specifically, between the lateral bar members 511 . The absorption plate 520 has an airfoil cross-sectional structure to facilitate the fluid flow in the sea. Here, the absorption plate 520 generates kinetic energy in a direction opposite to the direction in which the wave kinetic energy generated in the sea is applied. That is, since the absorption plate 520 generates kinetic energy while being rotated under the influence of the waves in the sea, the configuration of the diaphragm structure 300 is affected by the waves to minimize the change of the position.

At this time, a plurality of projections (not shown) may be formed in the longitudinal direction of the upper surface of the absorption plate 520 and the longitudinal direction of the lower surface of the absorption plate 520. The protrusions generate turbulence against the fluid on the upper surface and the lower surface of the absorption plate 520, thereby increasing thrust and lift. That is, the protrusions are affected by waves in the sea, and increase the kinetic energy generated when the absorption plate 520 rotates. In addition, dimples or protrusions may be formed instead of a plurality of protrusions on the top and bottom rims of the absorption plate 520, or on the entire upper and bottom surfaces of the absorption plate 520.

The elastic connecting member 530 absorbs the kinetic energy generated when the absorbing plate 520 generates kinetic energy by the wave kinetic energy generated in the sea. That is, when the elastic plate 520 is rotated at a predetermined angle or more, the elastic plate 530 is returned to its original position through the elastic restoring force and the rotational force of the elastic plate 520 Thereby absorbing it. One end of the elastic connection member 530 is connected to one side of the absorption plate 520 and the other end of the elastic connection member 530 is connected to a side of the horizontal bar member 511 ). Here, the elastic connecting member 530 may be made of rubber, synthetic resin, or coil spring having elastic restoring force, and the coil spring may be coated with rubber or synthetic resin. The number of the elastic connecting members 530 is not limited to two, and at least one of the elastic connecting members 530 may be selectively installed. As the number of the elastic connecting members 530 increases, However, the rotation due to the wave kinetic energy generated in the sea can not be stably performed.

As described above, in the float type offshore wind power generator combined with a farm in accordance with an embodiment of the present invention, the lower end of the tub-shaped aqueduct structure 300, which is enclosed by the aquarium net 400 outside the float 100, The fish and shellfish can be stably formed through the aqueduct structure 300 while maintaining a stable floating state at the sea through a simple construction structure that is connected and locked.

The balancing unit 500 may be connected to the aquarie structure 300 to absorb the wave motion energy transmitted to the aquarie structure 300 and to transmit the wave kinetic energy to the aquarium structure 300 and the float 100 can maintain a stable equilibrium state at the sea, thereby enabling stable culture and wind power generation of fishes and shellfishes within the diatomic structure 300.
