[0034] Specifically, the marine floating platform power generation system includes:

[0035] The platform body 1 and the fixing unit 2, wherein the platform body 1 is a semi-spherical structure with a hollow interior, and the bottom of the arc-shaped platform body 1 floats on the surface of the ocean; the first end of the fixing unit 2 is fixed to the bottom of the platform body 1, and the second end is fixed to a preset position of the ocean crust;

[0038] In the embodiment of the present application, the ocean floating platform power generation system utilizes a variety of renewable energy sources such as ocean temperature difference energy and tidal energy to generate electricity, which can effectively improve the power generation efficiency; further, through the cooperation of the semi-spherical platform body 1 and the power generation floating plate 5, the wind and wave resistance of the ocean floating platform power generation system is significantly improved, thereby better realizing the stable and continuous power generation of the ocean floating platform power generation system.

[0039] It should be noted that the hollow hemispherical structure can provide greater buoyancy, and at the same time improve the stability and anti-overturning ability of the platform body 1 by lowering the center of gravity of the platform body 1. In addition, the bottom of the temperature difference power generation unit 3 is connected to a cold water pipe 4 that penetrates deep into the ocean, ensuring that the temperature difference power generation unit 3 can obtain cold water from the deep ocean (that is, deep-sea cold water) to maintain the stability of the temperature difference effect.

[0046] The nacelle 81 is arranged in the middle of the top surface of the platform body 1; the straight blades 82 are distributed in the vertical direction, and the straight blades 82 are connected to the hub 84, the hub 84 is sleeved on the outside of the main shaft 83, and the hub 84 is rotatably connected to the main shaft 83; the bottom of the hub 84 is connected to the nacelle 81, and the nacelle 81 is used to convert the mechanical energy of the rotation of the hub 84 into electrical energy. Exemplarily, the hub 84 is connected to the input shaft of the generator to convert wind energy into electrical energy.

[0047] In the above-mentioned implementation, the ocean floating platform power generation system combines wind power generation, tidal power generation, and temperature difference power generation to improve power generation efficiency.

[0048] Optionally, the wind power generation unit 8 further includes a radial bearing 85;

[0049] Both ends of the wheel hub 84 are rotatably connected to the main shaft 83 via two radial bearings 85 .

[0050] Optionally, the wind power generation unit 8 further includes an upper support arm 86 and a lower support arm 87;

[0051] The top of the straight blade 82 is fixedly connected to the top of the hub 84 via the upper support arm 86 , and the bottom of the straight blade 82 is fixedly connected to the bottom of the hub 84 via the lower support arm 87 .

[0052] Optionally, the wind power generation unit 8 further comprises a cable 88, the cable 88 comprising an upper cable and a lower cable. One end of the upper cable is connected to the top of the straight blade 82, and the other end is rotatably connected to the top of the main shaft to ensure stability under high wind speed.

[0053] One end of the lower cable is connected to the bottom of the straight blade 82, and the other end is connected to the middle of the hub 84. The main function of the lower cable is to provide additional stability to prevent the blade from tilting or deflecting due to vibration during rotation.

[0054] In the above embodiment, the fixed connection between the straight blades 82 and the hub 84 is well ensured.

[0055] Optionally, the power generation floating plate 5 is in a rectangular shape, which makes the structure design of the power generation floating plate 5 reasonable and helps to fully utilize tidal energy for power generation.

[0056] Optionally, the number of the power generation floating plates 5 is 8-15. This can not only improve the efficiency of tidal power generation, but also ensure the stability of the platform body 1.

[0058] An entrance and an exit are arranged on the side wall of the platform body 1 corresponding to the temperature difference power generation unit 3 , and the hatch 9 is installed at the entrance and the exit.

[0059] In the above embodiment, the temperature difference power generation unit 3 can be conveniently installed and repaired through the hatch 9, and the operation is convenient.

[0060] For example, in specific applications, the center of gravity of the platform body 1 is lowered through the internal hollow semi-spherical structure, and the anti-overturning ability is significantly enhanced. Experimental data show that the maximum tilt angle of the ocean floating platform power generation system is kept within 2° under the conditions of wave height of 4 meters and wind speed of 30m / s, and the buoyancy is increased by 20%, which effectively reduces the impact of wind and waves on the ocean floating platform power generation system. Through the coordinated use of temperature difference power generation and tidal power generation, the power generation efficiency of the ocean floating platform power generation system is increased by 25% compared with the traditional system, achieving stable and continuous power output, ensuring that the ocean floating platform power generation system maintains efficient operation and wind and wave resistance in complex marine environments.

[0061] In the embodiment of the present application, the ocean floating platform power generation system effectively disperses the wave impact force through the design of the power generation floating plate 5 and the optimization of the center of gravity, thereby enhancing the stability of the ocean floating platform power generation system under strong wind and wave conditions. Moreover, the power generation floating plate 5 can maintain the balance of the platform body 1 under the action of tides and waves, thereby improving the wind and wave resistance performance of the ocean floating platform power generation system.

[0062] In addition, the ocean floating platform power generation system combines temperature difference energy and tidal energy, providing stable and efficient power output through the coordinated use of the two energy sources. Temperature difference power generation provides basic power, while tidal power generation provides efficient supplementary energy through tidal movement.
