[0046] It should be noted that the wind turbine blades 11 are located at the top of the wind turbine 10. Under the action of wind, the wind turbine blades 11 rotate and drive the gear box and generator inside the wind turbine generator compartment 12 to work, so as to convert wind energy into electrical energy.

[0051] Preferably, the floating aquaculture cages 40 are connected to form a square array via connecting pipes 41 , and every two aquaculture cages are connected via two high-strength connecting pipes 41 .

[0052] See also Figure 1 to Figure 3 As a preferred embodiment of the combined system of the conductor pipe wind turbine and the floating aquaculture cage of the present invention, the frame and shell of the floating aquaculture cage 40 and the connecting pipe 41 are steel structures.

[0053] Preferably, a plurality of floating aquaculture cages 40 are arranged around the conduit frame foundation in a square array, and every two floating cages are connected together by two connecting pipes 41. The frame and shell of the floating aquaculture cages 40 are made of high-rigidity steel structure, and the connecting pipes 41 also have high tensile and bending strength to ensure that the aquaculture cages will not disintegrate when hit by a ship.

[0054] See also Figure 1 to Figure 3 As a preferred embodiment of the combined system of the jacket-type wind turbine and the floating aquaculture cage of the present invention, the shell of the underwater part of the floating aquaculture cage 40 is a porous structure.

[0055] It should be noted that the floating aquaculture cage 40 floats on the sea surface, the frame and shell of the floating aquaculture cage 40 are made of high-rigidity steel structure, and the underwater part of the shell of the floating aquaculture cage 40 is a porous structure.

At the same time, the steel structure has good corrosion resistance and anti-aging properties, and can maintain the integrity and stability of the structure in long-term use, thus extending the service life of the aquaculture cage.

[0057] The porous structure can increase the flow rate of water flow, and at the same time, it also helps to maintain the fluidity of the aquaculture water body, improve the vitality and growth rate of the aquaculture organisms. The porous structure can promote the exchange of aquaculture water with the external environment, increase the dissolved oxygen content, improve water quality conditions, and provide a better growth environment for aquaculture organisms. The porous structure can reduce the attachment of suspended matter and organic matter in the water body, reduce the risk of cage pollution, and at the same time, it is also convenient for farmers to clean and maintain, keeping the aquaculture cages clean and hygienic.

The floating aquaculture cages 40 are connected to the working platform 20 through ropes 70, which reduces the setting of anchor points. Since the working platform 20 is fixed to the seabed through the pipe frame 30, this setting makes the floating aquaculture cages 40 have higher stability.

[0067] When the floating aquaculture cage 40 and the connecting pipe 41 are displaced by a ship impact, the anchor chain 50 and the suction anchor 60 will pull the floating cage to ensure that the ship and the floating aquaculture cage 40 will not impact the pipe frame 30 .

[0068] The combined system of the conductor frame wind turbine and the floating aquaculture cage of the present invention is a multifunctional facility that can achieve industrial diversification and protect the conductor frame 30 from ship collision accidents.
