The buoyancy structure 200 consists of a plurality of buoyancy bodies 210 configured to generate buoyancy, and a support structure 220 provided on the upper part of the buoyancy body 210. Each buoyancy body 210 is bound to each other and integrated with the support structure 220. The support structure 220 is connected and integrated with the main rope 14 by a plurality of connecting ropes, etc., and may be made of a steel structure to have sufficient rigidity. The buoyancy structure 200 is placed in the center or on either side of the fish farm 10. In this embodiment, the description and illustration are based on the arrangement in the center of the fish farm 10.

The power generation unit 300 is provided on the main rope 14 and the buoyancy structure 200, respectively, to realize eco-friendly energy harvesting.

The power generation unit 300 includes a wind power generation device 310 configured to generate power using wind power and provided at the center of the support structure 220. The wind power generation device 310 is provided with a tower equipped with blades and a turbine standing upright at the center of the support structure 220.

The power generation unit 300 is configured to generate power using sunlight and includes a plurality of solar power generation panels 320 provided on the upper surface of the support structure 220. The solar power generation panel 320 may also be installed on the tower structure of the wind power generation device 310, including the upper surface of the support structure 220.

The power generation unit 300 includes a plurality of tidal current power generation devices 330 each provided at the edge of the support structure 220 and having a turbine 334 that is rotated by tidal currents. As shown in FIGS. 2 and 3, the tidal current power generation device 330 is provided with an inflow prevention member 332A to prevent fish or foreign substances from entering, and has an installation portion 222 formed at the edge of the support structure 220. A case 332 installed vertically in the water, a turbine 334 installed to be rotatable vertically inside the case 332 with a plurality of blades, and the rotational kinetic energy of the turbine 334 It consists of a generator 336 provided on the upper part of the case 332 to be connected to the shaft of the turbine 334 to convert it into electrical energy. Since the turbine 334 is installed vertically in the water, as shown in FIG. 3, the rotational operation of the turbine 3374 can be performed smoothly no matter which direction the current acts.

The power generation unit 300 includes a wave power generator 340 for converting potential energy into electrical energy as it is shaken by waves. As shown in FIG. 4, the wave power generator 340 is divided into an upper and lower part, and a flow amplification space 342A is formed in the upper part partially filled with a liquid for flow amplification, and generates buoyancy in the lower part. It includes a case 342 in which a sealed buoyancy space 342B is formed. It includes a weight 344 that is provided vertically at the center of the bottom of the case 342 and forms the center of gravity of the case 342. It includes a connecting rope 346 connecting the case 342 and the main rope 14. When the case 342 is shaken by waves, it is configured to convert potential energy into electrical energy and includes at least one wave power generation module 348 provided in the buoyancy space 342B. The flow amplification space 342A is formed to be smaller than the buoyancy space 342B, but differently from this, the buoyancy space 342B may be formed to be smaller. The flow amplification space 342A may be shaped like a cone that is small at the top and wide at the bottom. The liquid for flow amplification may be composed of sea water, and may fill approximately 2/3 of the flow amplification space (342A). Additionally, a warning light may be provided at the top of the case 342. Various observation sensors or equipment may be installed in the buoyancy space 342B or outside of the case 342, and a battery may be provided to temporarily store the electrical energy generated in the wave power generation module 344.

The wave power generation module 348 is configured to convert the potential energy that changes when the buoy 16 is shaken in all directions based on the weight 344 by waves into electrical energy. In other words, the case 342 is configured to generate power by rotating when the case 342 repeats the process of being tilted along the wave surface by waves and being erected again.

The wave power generation module 348 is not limited to any one structure and can be configured in various ways. As an example, as shown in FIG. 5, a wave power generation turbine 348B for generating power through rotational motion is provided inside a hexahedral housing 348A having four sides, and each side of the housing 348A has a structure in which pendulums 348C, which perform pendulum movement due to the inclination of the case 342, are each coupled to a rotation axis. Due to this structure, when the case 342 is tilted by a wave, the pendulums 348C are tilted to one side and rotate each rotation axis, and the rotation force of each rotation axis is generated by the turbine ( 348B) is rotated to generate power.

In the wave power generation device 340 of this structure, the flow amplification space 342A formed in the upper part of the case 342 is partially filled with a liquid for flow amplification, a buoyancy space 342B is formed in the lower part, and the case 342 ) Because the weight 344 is provided on the bottom of the case 342, when waves act on the case 342, the case 342 shakes more significantly, thereby improving power generation efficiency. In other words, a weight 344 is provided on the bottom of the case 342 so that the center of gravity is at the bottom center, and the flow amplification space 342A at the upper side is filled with a liquid for flow amplification, so that the case 342 is caused by waves. ) is tilted and re-established or when tilted in another direction, the liquid filled in the flow amplification space (342A) freely floats in an independently unspecified direction and/or in the tilting direction of the case (342). Therefore, the case 342 is shaken more significantly by adding the shaking caused by the sloshing of the liquid filled in the flow amplification space (342A) to the shaking caused by the waves, and the shaking is amplified and continues, so the wave power generation built into the buoyancy space (342B) The power generation efficiency of module 348 can be significantly improved.

The wave power generation device 340 according to another embodiment is the same as the above-described embodiment except that the case 342 is applied as a buoy 16, as shown in FIG. 6. That is, the interior of the buoy 16 is divided into upper and lower parts, and a flow amplification space (16A) partially filled with flow amplification liquid is formed at the upper part, and a buoyancy space (16A) is formed at the lower part and is blocked from the outside to generate buoyancy ( 16B) is formed. The bottom of the buoy 16 is connected to the main rope 14 by a connecting rope 346. At least one wave power generation module 344 is installed in the buoyancy space (16B). By applying the wave power generation device 340 to the buoy 16, a separate case 342 becomes unnecessary. Since the connecting rope 346 is connected to the main rope 14 and serves as a weight 344, a separate weight 344 is not necessary.

The power generation unit 300 may include a seawater battery 350. The seawater battery 350 is a device that stores and generates electrical energy by reacting with seawater, and is environmentally friendly because it uses seawater as an electrolyte. The seawater battery 350 includes an anode part including a cathode submerged in seawater, a cathode part including an anode impregnated in an organic electrolyte, and the anode part located between the anode part and the cathode part. It contains a solid electrolyte that separates the positive and negative electrodes.

However, when generating electrical energy in the seawater battery 350, hydrogen gas is generated from the cathode. The present invention may further include a hydrogen storage tank for storing explosive hydrogen generated in the seawater battery 350.

The power generation unit 300 includes a fuel cell 360 for generating power by receiving hydrogen stored in a hydrogen storage tank. The fuel cell 360 receives high-purity hydrogen gas from a hydrogen storage tank, generates power through a reaction with hydrogen gas, and generates water and heat as by-products. Since this method of producing power using the fuel cell 360 can be understood from known technology, detailed description will be omitted.

As shown in FIG. 7, the central control device 400 controls the wind power generation device 310, the solar power generation panel 320, the tidal current power generation device 330, and the wave power generation device 340 of the power generation unit 300. , an energy storage unit 420 for storing electricity generated by the seawater battery 350 and the fuel cell 360, a communication unit 430 for communicating with the management system 500 via wireless or wired, and a power generation unit ( It is configured to include a control unit 440 for controlling the energy storage unit 420 and the communication unit 430.

Meanwhile, the buoyancy structure 200 may be equipped with observation sensors to observe or sense salinity, water temperature, current direction, etc.

By applying the combined power generation system 100 configured as described above to the fish farm 10, it is possible to not only cultivate fish or shellfish using the fish farm 10, but also reduce the power consumed in the fish farm 10. It can be supplied and used from the self-produced combined power generation system 100.

In particular, the combined power generation system 100 applied to the fish farm 10 can collect energy generated from natural energy sources such as wind, sunlight, tide, seawater, etc. and convert it into useful electrical energy, thereby enabling energy harvesting. It becomes possible to realize it.

In addition, manufacturing costs can be significantly reduced by realizing wave power generation by utilizing the idle buoy 16.
