[0040] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0041] Example 1:

[0042] See also Figures 1-6The floating platform based on electromagnetic active suspension 3 includes: a wind turbine float 1; a buoy 2; an electromagnetic active suspension 3, wherein the electromagnetic active suspension 3 includes a movable bracket 301, an electromagnetic actuator 302 and a hinge bracket 303; wherein the movable bracket 301 includes a bracket body 3011 and a first swing arm 3012 and a second swing arm 3013 hinged at both ends of the bracket body 3011, the bracket body 3011 is connected to the side of the wind turbine float 1; the electromagnetic actuator 302 is hinged to the side of the wind turbine float 1; One end is hinged to an end of the bracket body 3011 close to the first swing arm 3012, and the other end of the electromagnetic actuator 302 is hinged to an end of the second swing arm 3013 away from the bracket body 3011; one side of the hinge bracket 303 is connected to the float 2, and the two ends of the other side of the hinge bracket 303 are respectively hinged to an end of the first swing arm 3012 away from the bracket body 3011 and an end of the second swing arm 3013 away from the bracket body 3011.

[0043] like Figure 1 、 Figure 2 and Figure 3 As shown, in this embodiment, the floating platform based on the electromagnetic active suspension 3 includes the wind turbine float 1, the buoy 2 and the electromagnetic active suspension 3, wherein the wind turbine float 1 is used to carry the wind turbine generator, the electromagnetic active suspension 3 is used to connect the wind turbine float 1 and the buoy 2, the electromagnetic active suspension 3 can play a role in actively resisting wind and wave loads, and the buoy 2 is used to provide buoyancy.

[0044] Specifically, the electromagnetic active suspension 3 includes the movable bracket 301, the electromagnetic actuator 302 and the hinge bracket 303; wherein the movable bracket 301 includes the bracket body 3011, the first swing arm 3012 and the second swing arm 3013, one side of the bracket body 3011 is detachably connected to the side of the wind turbine float 1 to facilitate disassembly and assembly, the right end of the first swing arm 3012 is rotatably connected to the top of the bracket body 3011, the right end of the second swing arm 3013 is rotatably connected to the bottom end of the bracket body 3011, the top end of the right side of the hinge bracket 303 is hinged to the left end of the first swing arm 3012, the bottom end of the right side of the hinge bracket 303 is hinged to the left end of the second swing arm 3013, and the left side of the hinge bracket 303 is detachably connected to the buoy 2 to facilitate disassembly and assembly. The electromagnetic active suspension 3 is disassembled or assembled; the top of the electromagnetic actuator 302 is hinged to the top of the support body 3011, and the bottom of the electromagnetic actuator 302 is hinged to the left end of the second swing arm 3013. When the buoy 2 is impacted by wind and waves and floats, the buoy 2 transmits the wave load to the hinge bracket 303 and the movable bracket 301, and the movable bracket 301 transmits the wave load to the electromagnetic actuator 302. During this process, the hinge bracket 303 drives the first and second swing arms 3012 and 3013 to rotate around the support body 3011. The electromagnetic actuator 302 then expands and contracts in real time according to the wave load, generating a force opposite to the wind and wave torque, actively offsetting the rotation of the first and second swing arms 3012 and 3013, thereby preventing the floating platform from swaying. In existing ballast tank structures, swaying of floating platforms is controlled by adjusting the water volume in the tanks to change the platform's center of gravity and buoyancy distribution, thereby suppressing sway. This process involves the physical migration of water, which takes time and exhibits hysteresis. The water velocity in a pipe is typically 1-3 m / s. For a 10-meter pipe, a single adjustment requires at least 3-10 seconds. The electromagnetic active suspension 3 provided by the present invention acts directly on the platform structure, eliminating the need to move large amounts of material. Compared to existing ballast tank stabilization methods, this method offers a more immediate vibration damping response and lower hysteresis. Furthermore, compared to existing floating platforms employing ballast tanks, the present invention avoids excessive tension in the mooring system 4, thereby preventing excessive stress on the floating platform and promoting structural stability.

[0045] like Figure 4As shown, further, the electromagnetic actuator 302 includes a sleeve 3021, a connecting seat 3022, a connecting rod 3023 and a spring 3024; one end of the sleeve 3021 is hinged to the end of the second swing arm away from the bracket body 3011, and a motor (not shown) is provided in one end of the sleeve 3021; ​​the connecting seat 3022 is hinged to the end of the bracket body 3011 close to the first swing arm 3012; one end of the connecting rod 3023 is rotatably connected to the connecting seat 3022, and the other end extends into the sleeve 3021 and is threadedly connected to the motor, so that the connecting rod 3023 is driven by the motor to move along the length direction of the sleeve 3021; ​​one end of the spring 3024 is fixedly sleeved on the outside of 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 motor (not shown) is provided in the bottom end of the sleeve 3021, the top end of the sleeve 3021 is open, the connecting seat 3022 is provided at the top end of the bracket body 3011, the top end of the connecting rod 3023 is rotatably connected to the connecting seat 3022, and the bottom end of the connecting rod 3023 is threadedly connected to the motor. For example, an external thread section is provided on the rotating shaft of the motor, and an internal thread section is provided at the bottom end of the connecting rod 3023. After the motor rotates The connecting rod 3023 can be driven to rotate and extend or retract along the length of the sleeve 3021. 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 mounted outside the sleeve 3021. When the motor drives the connecting rod 3023 to extend from the sleeve 3021, the spring 3024 is stretched. When the motor drives the connecting rod 3023 to retract into the sleeve 3021, the spring 3024 is retracted. The motor actively drives the extension or retraction of the spring 3024, thereby generating a force opposite to the wind and wave torque, thereby offsetting the wind and wave load and preventing the swaying of the floating platform. For example, when the movable support 301 is subjected to wind and wave loads and intends to compress the spring 3024, the motor actively drives the spring 3024 to extend; when the movable support is subjected to wind and wave loads and intends to extend the spring 3024, the motor actively drives the spring 3024 to compress. Simultaneously, the electromagnetic actuator 302 also includes the sensor and the control module. The control module is electrically connected to the sensor and the motor. The sensor is used to sense wind and wave loads in advance. For example, the sensor is mounted on the buoy 2. When the sensor senses wave loads, the control module promptly controls the motor to drive the connecting rod 3023, actively extending or contracting the spring 3024 in advance through the connecting rod 3023. In this embodiment, the motor is electrically connected to a wind turbine, which supplies power to the motor and the control module.

[0047] At the same time, the electromagnetic active suspension 3 provided in the embodiment of the present invention has a wave energy recovery effect, that is, after the buoy 2 transfers the wave load to the electromagnetic actuator 302, the spring 3024 is affected by the wave load and also drives the connecting rod 3023 to move. The motor in the sleeve 3021 is affected by the movement of the spring 3024 and the connecting rod 3023. A certain amount of electrical energy will also be generated inside the motor and transferred to the wind turbine for electrical energy recovery. Existing wind turbines usually have an energy storage function. This part of the recovered electrical energy can be used by the motor to actively drive the connecting rod 3023 and the spring 3024 to move.

[0048] Furthermore, the electromagnetic actuator 302 also includes a positioning ring 3025, which is provided with an internal thread. The outer side of the sleeve 3021 is provided with an external thread section. The positioning ring 3025 is sleeved on the external thread section and threadedly connected to the sleeve 3021. One end of the spring 3024 is sleeved on the outer side of the sleeve 3021 and fixedly connected to the positioning ring 3025.

[0049] Specifically, the positioning ring 3025 is threadably mounted on the externally threaded section of the sleeve 3021 via its internal threads, thereby threadably connecting to the sleeve 3021. The length of the spring 3024 can be adjusted by rotating the positioning ring 3025, thereby adjusting the stiffness of the electromagnetic active suspension 3. For example, when wind and wave loads are low, the stiffness of the electromagnetic active suspension 3 is adjusted to a moderately soft setting, effectively absorbing small vibrations while avoiding energy waste. Furthermore, in this embodiment, the positioning ring 3025 is positioned opposite the connecting seat 3022, and a hanging ring (not shown) is provided on the side of the positioning ring 3025 opposite the connecting seat 3022. Hooks (not shown) are provided at each end of the spring 3024. The spring 3024 is detachably connected to the positioning ring 3025 and the connecting seat 3022 via the combination of the hooks and hanging rings, facilitating regular replacement of the spring 3024.

[0050] like Figure 5 As shown, in this embodiment, the electromagnetic actuator 302 further includes a damping piston 3026, which is fixedly mounted on one end of the connecting rod 3023. The sidewall of the damping piston 3026 abuts against the inner wall of the sleeve 3021. Specifically, the damping piston 3026 generates a certain frictional force when moving relative to the inner wall of the sleeve 3021. Therefore, the damping piston 3026 can further enhance the electromagnetic active suspension 3's ability to resist wind and waves and maintain the stability of the floating platform.

[0051] Furthermore, a connecting plate 3014 is provided on one side of the bracket body 3011 . The connecting plate 3014 is provided with screw holes. The connecting plate 3014 is fixedly connected to the wind turbine float 1 by engaging screws with the screw holes.

[0052] Specifically, the connecting plate 3014 is circular in shape and is provided with multiple screw holes, evenly spaced around the circumference of the connecting plate 3014 to form a circle. Each screw hole is fitted with a screw for connection to the wind turbine buoy 1. The circular structure of the connecting plate 3014 evenly distributes external loads in all directions, preventing stress concentration. Compared to square or other irregular shapes, the circular connecting plate 3014 ensures more balanced forces between the bracket body 3011 and the wind turbine buoy 1 when subjected to wind and wave impacts, effectively improving the stability and durability of the connection structure. Multiple evenly distributed screw connection points evenly transfer wind and wave loads to the bracket body 3011 and the wind turbine buoy 1, preventing connection failure caused by local overload. For example, when encountering lateral forces caused by strong winds, the circumferentially distributed screws work synergistically to distribute the forces, preventing excessive stress on a single connection point. Even if individual screws become loose or damaged, the remaining screws maintain the basic stability of the connection structure, buying time for equipment maintenance and reducing the risk of safety accidents caused by connection failure. Therefore, the design of the circular connection plate 3014 and the evenly distributed screw holes around the circumference enable the connection structure to effectively withstand wind and wave loads from various directions, significantly improving the stability of the electromagnetic active suspension 3 system in complex marine environments, reducing equipment failures caused by loose connections, and ensuring the reliable operation of offshore wind turbines.

[0053] Furthermore, the two ends of the bracket body 3011 are respectively provided with a first rotating shaft 3015 and a second rotating shaft 3016 which are relatively distributed. 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, a ball joint 3031 is respectively provided at both ends of the other side of the hinge bracket 303. One end of the other side of the hinge bracket 303 is ball-jointed to the end of the first swing arm 3012 away from the bracket body 3011 through the ball joint 3031 thereon, and the other end of the other side of the hinge bracket 303 is ball-jointed to the end of the second swing arm 3013 away from the bracket body 3011 through the ball joint 3031 thereon.

[0055] Specifically, the ball joint 3031 includes a hinge tube (not shown) and a hinge rod (not shown) having 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 having the spherical hinge joint is movably arranged in the hinge tube. The two ends of the hinge tube respectively limit the spherical hinge joint to prevent the spherical hinge joint from detaching from the hinge tube. The hinge tube is cylindrical. The end of the hinge rod having the spherical hinge joint can move telescopically in the hinge tube, and the end of the hinge rod having the spherical hinge joint can rotate in the hinge tube. The spherical hinge joint of the hinge rod can rotate in multiple directions within the hinge tube, allowing the hinge bracket 303 to swing within a certain angle range. When the floating platform is tilted by lateral wind and wave forces, the hinge rod rotates in the hinge tube through the spherical hinge joint, adjusting its own posture, so that the electromagnetic active suspension 3 can better adapt to the movement of the platform, actively offset the sway of the floating platform, and maintain the stability of the floating platform.

[0056] Furthermore, the wind turbine float 1 includes a central column 101 and a support base 102, the central column 101 has a plurality of supporting legs, and the side of each supporting leg is respectively connected to an electromagnetic active suspension 3; the support base 102 has a plurality of corners, and each corner is respectively connected to each supporting leg in a one-to-one correspondence.

[0057] like Figure 6 As shown, specifically, the central column 101 is composed of three L-shaped pipes, one end of which is connected to a point at the same time, and the angle between the three L-shaped pipes is 120 degrees. This 120-degree angle design can evenly distribute external loads in all directions, effectively avoiding stress concentration. The other ends of the three L-shaped pipes form three legs. The support base 102 has a triangular structure, and circular bases are respectively provided at the three corners of the support base 102. The connection point of the three L-shaped pipes is located on the central axis of the support base 102. The legs of the three L-shaped pipes are fixedly connected to the three circular bases in a one-to-one correspondence, and the contact surface of the circular bases is larger than the contact surface of the L-shaped pipe legs. The circular bases are respectively provided at the three corners of the support base 102. The circular bases are not only convenient for connecting with the legs of the central column 101, but also can evenly distribute the pressure from the central column 101 through a larger contact area. The intersection of the three L-shaped pipes is precisely located on the central axis of the support base 102, ensuring the balance of the center of gravity of the entire floating structure and effectively reducing the shaking 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, the mooring system 4 is provided with a plurality of mooring ropes, one end of each mooring system 4 is respectively connected to the bottom side of each corner of the support base 102, and the other end of the mooring system 4 is used to anchor the floating platform. The mooring system 4 includes a mooring cable and an anchoring foundation.

[0061] In summary, the embodiment of the present invention provides a floating platform based on electromagnetic active suspension 3, which includes: a wind turbine float 1; a buoy 2; an electromagnetic active suspension 3, wherein the electromagnetic active suspension 3 includes a movable bracket 301, an electromagnetic actuator 302 and a hinge bracket 303; wherein the movable bracket 301 includes a bracket body 3011 and a first swing arm 3012 and a second swing arm 3013 hinged at both ends of the bracket body 3011, the bracket body 3011 is connected to the side of the wind turbine float 1; the electromagnetic actuator 302 ... One end of the electromagnetic actuator 302 is hinged to the end of the support body 3011 near the first swing arm 3012, and the other end of the electromagnetic actuator 302 is hinged to the end of the second swing arm 3013 away from the support body 3011. One side of the hinge bracket 303 is connected to the buoy 2, and the other ends of the hinge bracket 303 are respectively hinged to the end of the first swing arm 3012 away from the support body 3011 and the end of the second swing arm 3013 away from the support body 3011. In the present invention, when the buoy 2 is struck by wind and waves and floats, the buoy 2 transfers the wave load to the hinge bracket 303 and the movable bracket 301. The movable bracket 301 transfers the wave load to the electromagnetic actuator 302. The electromagnetic actuator 302 expands and contracts in real time according to the wave load and generates a force opposite to the wind and wave torque, actively offsetting the sway of the floating platform. Compared with the existing ballast tank stabilization method, the vibration reduction response is more timely and the lag is lower.
