The support body 3011 is connected to a side of the fan floating body 1. One end of the electromagnetic actuator 302 is hinged to one end of the support body 3011 close to the first swing arm 3012, and the other end of the electromagnetic actuator 302 is hinged to one end of the second swing arm 3013 away from the support body 3011. One side of the hinge support 303 is connected to the pontoon 2, and both ends of the other side of the hinge support 303 are hinged to one end of the first swing arm 3012 away from the support body 3011 and one end of the second swing arm 3013 away from the support body 3011, respectively.

[0043] As shown in Figure 1 , Figure 2 and Figure 3 In the embodiment, the floating platform based on the electromagnetic active suspension 3 comprises the fan floating body 1, the pontoon 2, and the electromagnetic active suspension 3.

The electromagnetic active suspension 3 can play a role of actively resisting a wind and wave load. The pontoon 2 is used to provide buoyancy.

[0044] Specifically, the electromagnetic active suspension 3 comprises the movable support 301, the electromagnetic actuator 302 and the hinge support 303; wherein the movable support 301 comprises the support body 3011, the first swing arm 3012 and the second swing arm 3013, one side of the support body 3011 is detachably connected with the side of the wind turbine floating body 1, so as to facilitate disassembly and assembly, the right end of the first swing arm 3012 is rotationally connected with the top end of the support body 3011, the right end of the second swing arm 3013 is rotationally connected with the bottom end of the support body 3011, the top end of the right side of the hinge support 303 is hinged with the left end of the first swing arm 3012, the bottom end of the right side of the hinge support 303 is hinged with the left end of the second swing arm 3013, the left side of the hinge support 303 is detachably connected with the buoy 2, so as to facilitate disassembly or assembly of the electromagnetic active suspension 3; the top end of the electromagnetic actuator 302 is hinged with the top end of the support body 3011, the bottom end of the electromagnetic actuator 302 is hinged with the left end of the second swing arm 3013, when the buoy 2 is floated due to the impact of wind and waves, the buoy 2 transmits wave load to the hinge support 303 and the movable support 301, the movable support 301 transmits wave load to the electromagnetic actuator 302, in this process, the hinge support 303 drives the first swing arm 3012 and the second swing arm 3013 to rotate around the support body 3011, and the electromagnetic actuator 302 extends or contracts in real time according to the wave load to generate a force opposite to the wind and wave torque, thereby actively offsetting the rotation of the first swing arm 3012 and the second swing arm 3013, and avoiding the floating platform from swaying.

[0045] As Figure 4As shown, further, the electromagnetic actuator 302 comprises a sleeve 3021, a connecting seat 3022, a connecting rod 3023 and a spring 3024; one end of the sleeve 3021 is hinged to one end of the second swing arm away from the support body 3011, and a motor (not shown) is arranged in one end of the sleeve 3021; the connecting seat 3022 is hinged to one end of the support body 3011 close to the first swing arm 3012; one end of the connecting rod 3023 is rotationally connected to the connecting seat 3022, and the other end of the connecting rod 3023 extends into the sleeve 3021 and is threadedly connected to the motor, so as to drive the connecting rod 3023 to move along the length direction of the sleeve 3021 by the motor; one end of the spring 3024 is fixedly sleeved outside the sleeve 3021, and the other end of the spring 3024 is connected to the connecting seat 3022.

[0046] Specifically, the bottom end of the sleeve 3021 is hinged to the left end of the second swing arm 3013, the bottom end of the sleeve 3021 is provided with the motor (not shown), the top end of the sleeve 3021 is open, the connecting seat 3022 is arranged at the top end of the support body 3011, the top end of the connecting rod 3023 is rotationally connected to the connecting seat 3022, the bottom end of the connecting rod 3023 is threadedly connected to the motor, for example, the rotating shaft of the motor is provided with an external threaded section, the bottom end of the connecting rod 3023 is provided with an internal threaded section, the motor can drive the connecting rod 3023 to rotate and extend out of or retract into the sleeve 3021 along the length direction of the sleeve 3021 after rotation, the top end of the spring 3024 is fixedly connected to the connecting seat 3022, and the bottom end of the spring 3024 is fixedly sleeved outside the sleeve 3021, when the motor drives the connecting rod 3023 to extend out of the sleeve 3021, the spring 3024 will be stretched, and when the motor drives the connecting rod 3023 to retract into the sleeve 3021, the spring 3024 will be retracted. The motor actively drives the stretching or retraction of the spring 3024 to generate a force opposite to the wind wave torque, thereby offsetting the wind wave load, so as to avoid the swing of the floating platform. For example, when the movable support 301 is subjected to the wind wave load and tends to compress the spring 3024, the motor actively drives the spring 3024 to stretch, and when the movable support is subjected to the wind wave load and tends to stretch the spring 3024, the motor actively drives the spring 3024 to compress. At the same time, the electromagnetic actuator 302 further comprises the sensor and the control module, the control module is electrically connected to the sensor and the motor, the sensor is used to sense the wind wave load in advance, for example, the sensor is installed at the buoy 2, when the sensor senses the wave load, the control module timely controls the motor to drive the connecting rod 3023, and the spring 3024 is actively stretched or retracted in advance through the connecting rod 3023. The motor in the embodiment is electrically connected to the wind turbine, and the wind turbine supplies power to the motor and the control module.

[0047] At the same time, the electromagnetic active suspension 3 provided by the embodiment of the present application has a wave energy recovery effect, that is, after the buoy 2 transmits the wave load to the electromagnetic actuator 302, the spring 3024 is also driven to move by the wave load, the motor in the sleeve 3021 is also affected by the movement of the spring 3024 and the connecting rod 3023, and a certain amount of electrical energy is generated in the motor and transmitted to the wind turbine for electrical energy recovery. The existing wind turbine usually has a power storage function, and the part of the recovered electrical energy can be used to actively drive the connecting rod 3023 and the spring 3024 to move.

[0048] Further, the electromagnetic actuator 302 further comprises a positioning ring 3025 provided with an internal thread, an outer thread section is provided on the outer side of the sleeve 3021, the positioning ring 3025 is sleeved on the outer thread section and is threadedly connected with the sleeve 3021, and one end of the spring 3024 is sleeved on the outer side of the sleeve 3021 and is fixedly connected with the positioning ring 3025.

[0049] Specifically, the positioning ring 3025 is sleeved on the outer thread section of the sleeve 3021 through the internal thread thereon to be threadedly connected with the sleeve 3021, the length of the spring 3024 can be adjusted by rotating the positioning ring 3025, so that the hardness of the electromagnetic active suspension 3 is adjusted. For example, when the wind and wave load is small, the hardness of the electromagnetic active suspension 3 is moderately soft, which can efficiently absorb small-amplitude vibration and avoid energy waste. Meanwhile, the positioning ring 3025 in the embodiment is oppositely arranged with the connecting seat 3022, and a hanging ring (not shown) is respectively arranged on the side of the positioning ring 3025 opposite to the connecting seat 3022, and hooks (not shown) are respectively arranged on the two ends of the spring 3024, and the spring 3024 is detachably connected with the positioning ring 3025 and the connecting seat 3022 through the combination of the hooks and the hanging ring, so as to facilitate the periodical replacement of the spring 3024.

[0050] As shown in Figure 5 In the embodiment, the electromagnetic actuator 302 further comprises a damping piston 3026, the damping piston 3026 is fixedly sleeved on one end of the connecting rod 3023, and the side wall of the damping piston 3026 abuts against the inner wall of the sleeve 3021. Specifically, the damping piston 3026 has a certain friction force when moving relative to the inner wall of the sleeve 3021, so that the performance of the electromagnetic active suspension 3 in resisting wind and wave to maintain the stability of the floating platform can be further enhanced through the damping piston 3026.

[0051] Further, one side of the support body 3011 is provided with a connecting plate 3014, the connecting plate 3014 is provided with a screw hole, and the connecting plate 3014 is fixedly connected with the fan floating body 1 through cooperation of a screw and the screw hole.

[0052] Specifically, the connecting plate 3014 is circular in shape, and a plurality of screw holes are arranged on the connecting plate 3014. The screw holes are uniformly distributed along the circumference of the connecting plate 3014 and form a circle. Screws for connecting the wind turbine floating body 1 are arranged in the screw holes. The circular structure of the connecting plate 3014 can uniformly disperse external loads in all directions and avoid stress concentration. Compared with a square or other irregular shape, the circular connecting plate 3014 can make the stress between the support body 3011 and the wind turbine floating body 1 more balanced when bearing the impact force of wind and waves, effectively improving the stability and durability of the connecting structure. The plurality of uniformly distributed screw connection points can uniformly transmit the wind and wave load to the support body 3011 and the wind turbine floating body 1, preventing connection failure caused by local overload. For example, when encountering lateral force caused by strong wind, the circumferentially distributed screws can work together to disperse the force, avoiding excessive stress on a single connection point. Even if individual screws loosen or are damaged, other screws can still maintain the basic stability of the connection structure, giving time for equipment maintenance and reducing the risk of safety accidents caused by connection failure. Therefore, the circular connecting plate 3014 and the circumferentially distributed screw holes can effectively resist wind and wave loads from different directions, greatly improve the stability of the electromagnetic active suspension 3 system in complex marine environments, reduce equipment failures caused by loose connections, and ensure the reliable operation of offshore wind turbines.

[0053] Furthermore, the support body 3011 is provided with a first rotating shaft 3015 and a second rotating shaft 3016 at opposite ends, respectively. One end of the first swing arm 3012 is rotatably connected to the first rotating shaft 3015, and one end of the second swing arm 3013 is rotatably connected to the second rotating shaft 3016.

[0054] In this embodiment, the other side of the hinge support 303 is provided with a spherical hinge part 3031 at both ends. One end of the other side of the hinge support 303 is connected to the first swing arm 3012 away from the support body 3011 through the spherical hinge part 3031 thereon, and the other end of the other side of the hinge support 303 is connected to the second swing arm 3013 away from the support body 3011 through the spherical hinge part 3031 thereon.

[0055] Specifically, the ball joint 3031 includes a hinge cylinder (not shown) and a hinge rod (not shown) with a spherical hinge joint at one end. One end of the hinge rod is fixedly connected to the end of the hinge bracket 303. The end of the hinge rod with the spherical hinge joint is movably disposed in the hinge cylinder. Both ends of the hinge cylinder limit the spherical hinge joint to prevent it from detaching from the cylinder. The hinge cylinder is cylindrical. The end of the hinge rod with the spherical hinge joint can extend and retract within the hinge cylinder, and the end of the hinge rod with the spherical hinge joint can rotate within the cylinder. The spherical hinge joint of the hinge rod can rotate in multiple directions within the hinge cylinder, allowing the hinge bracket 303 to swing within a certain angle range. When the floating platform tilts due to lateral wind and wave forces, the hinge rod rotates within the hinge cylinder through the spherical hinge joint to adjust its own attitude, enabling the electromagnetic active suspension 3 to better adapt to the platform's movement, actively counteract the floating platform's sway, and maintain the platform's stability.

[0056] Furthermore, the wind turbine float 1 includes a central column 101 and a support base 102. The central column 101 has several legs, and each leg is connected to an electromagnetic active suspension 3 on its side. The support base 102 has several corners, and each corner is connected to each leg in a corresponding manner.

[0057] like Figure 6 As shown, specifically, the central column 101 is composed of three L-shaped tubes, one end of which is connected at one point, and the included angle between the three L-shaped tubes is 120°. This 120° angle design can evenly distribute the external load in all directions, effectively avoiding stress concentration. The other end of the three L-shaped tubes forms three legs. The support base 102 has a triangular structure, and each of the three corners of the support base 102 is provided with a circular base. The connection point of the three L-shaped tubes is located on the central axis of the support base 102. The legs of the three L-shaped tubes are fixedly connected to the three circular bases one by one, and the contact surface of the circular bases is larger than the contact surface of the legs of the L-shaped tubes. The circular bases at the three corners of the support base 102 not only facilitate the connection with the legs of the central column 101, but also evenly distribute the pressure from the central column 101 through a larger contact area. The intersection of the three L-shaped tubes is precisely located on the central axis of the support base 102, ensuring the balance of the entire floating structure and effectively reducing swaying caused by the shift of the center of gravity.

[0058] Furthermore, the floating platform based on electromagnetic active suspension 3 also includes: a mooring system 4, which has several mooring systems, one end of which is connected to the bottom side of each corner of the support base 102, and the other end of which is used to anchor the floating platform. The mooring system 4 includes mooring cables and anchoring foundations.
