[0023] In the following, the present invention will be explained in more detail in conjunction with drawings and detailed embodiments so that the above object, features, and advantages of the present invention will be more clearly and easily understood. Obviously, the described embodiments do not represent all embodiments, but only a part of the embodiments. All other embodiments obtained by one of ordinary skill in the art, provided that no creative work is performed, based on the embodiments in the present invention should be considered to be covered by the scope of the present invention.

[0024] In order to be adapted to a marine environment and to install a wind turbine in the sea, an embodiment of the present invention provides a floating wind turbine, for which particular reference is made to Fig. 1 can be taken; as in Fig. 1, the floating wind turbine may comprise a nacelle 1, a wind turbine 2, a support structure 3, a yaw system, spoilers 6, a drive and a plurality of cylindrical floating bodies 4; wherein the nacelle 1 is connected to the wind turbine 2; and wherein the nacelle 1 is connected to the plurality of cylindrical floating bodies 4 via the support structure 3; and wherein the support structure 3 comprises a plurality of connecting units; and wherein two ends of one of the plurality of connecting units are each connected perpendicularly to the gondola 1 and the corresponding cylindrical floating body 4, and wherein two ends of the other connecting units are each connected to the gondola 1 and the corresponding cylindrical floating body 4, and wherein the other connecting units enclose an angle θ° with the gondola 1 and the corresponding cylindrical floating body 4; 0<θ°<90°; and wherein the yaw system is used to adjust the angle of the wind turbine 2 and / or the nacelle 1; and wherein the spoilers 6 are arranged along the circumferential direction of the cylindrical floating bodies 4; and wherein the spoilers are connected to the cylindrical floating bodies 4 via a bearing, and wherein the spoilers 6 are or can be telescopic relative to the cylindrical floating body 4; and wherein the spoilers 6 are connected to the drive; and wherein the drive is used to drive the spoilers 6 around the cylindrical floats 4.

[0025] In the embodiment of the present invention, the floating wind turbine may comprise a nacelle 1, a wind turbine 2, a support structure 3, a yaw system, and a plurality of cylindrical floating bodies 4; the nacelle 1 may be connected to the wind turbine 2; when the wind turbine 2 rotates, the kinetic energy of the rotation is transferred through the shaft of the wind turbine 2 to the gearbox in the nacelle 1. The gearbox transmits the increased rotational speed to the generator. The generator includes one or more magnets and a coil (or stator) inside. As the magnets rotate, they create a variable magnetic field in the stator coil, which induces an electric current.

[0026] The sea is different from land; there is no soil on the sea surface on which the wind turbine can be installed; therefore, several cylindrical floats 4 are required to allow the nacelle 1 and the wind turbine 2 to be positioned above the sea surface. The design and function of the cylindrical floats 4 focus, for example, on providing buoyancy, stability, and structural support.

[0027] The main function of the cylindrical floats 4 is to provide sufficient buoyancy to support the weight of the nacelle 1, the wind turbine 2, the supporting structure 3, and the like. The cylindrical float 4 can be made of a lightweight but stable material, e.g., high-density polyethylene, steel, or concrete.

[0028] To ensure stability, the cylindrical floating body 4 can be designed to have a certain width and height in order to increase the volume of its underwater part and thereby increase its resistance to wind, waves and tipping.

[0029] The cylindrical floating body 4 is connected to the nacelle 1, the wind turbine 2 and the like via the support structure 3 to provide the necessary structural support for the nacelle 1, the wind turbine 2 and the like.

[0030] In addition, the cylindrical float 4 must have good corrosion resistance and durability as it is exposed to the marine environment for a long time.

[0031] In the embodiment of the present invention, the floating wind turbine does not have a tower, wherein the nacelle 1 in the floating wind turbine may be fixedly connected to the plurality of cylindrical floating bodies 4 via the support structure 3; and wherein the support structure 3 may comprise a plurality of connecting units, which may be a truss structure or a steel tube.

[0032] In practice, two ends of one of the plurality of connecting units may be perpendicular to the nacelle 1 and the corresponding cylindrical floating body 4 and may each be fixedly connected to the nacelle 1 and the corresponding cylindrical floating body 4.

[0033] Two ends of the other connecting units except this connecting unit can be connected to the nacelle 1 and the corresponding cylindrical floating body 4, respectively, wherein the other connecting units form an angle θ° with the nacelle 1 and the corresponding cylindrical floating body 4; where 0<θ°<90°, and where 0<θ°<90°, respectively. With this structure, the stability of the floating wind turbine can be improved.

[0034] In some executable embodiments, the floating wind turbine may further comprise a yaw system with which the angle of the wind turbine 2 and / or the nacelle 1 can be adjusted to ensure that the wind turbine 2 is always facing the wind direction, thereby maximizing the efficiency of wind energy generation.

[0035] The yaw system may include, for example, the following parts: a yaw bearing: the yaw bearing is the core component of the yaw system, allowing the nacelle 1 to rotate relative to the connecting units; the yaw bearing is typically designed as a large ring-shaped structure mounted on top of the connecting unit and connected to the base of the nacelle 1; a yaw actuator: the yaw actuator drives the yaw bearing to rotate to adjust the direction of the nacelle 1; the yaw actuator can be electric, hydraulic, or pneumatic, and the specific choice depends on the design requirements and application scenarios; a yaw control system: the yaw control system is the "brain" of the yaw system, which receives signals from wind sensors and controls the operation of the yaw drive according to predefined algorithms and logic; the control system usually consists of sensors, control units, and actuators; a yaw brake: the yaw brake is used to provide the necessary braking force during yaw adjustment to prevent the nacelle 1 from rotating excessively in windy conditions; the brake can be mechanical, hydraulic or electromagnetic; In the yaw system, a sensor (e.g., a wind vane) is mounted on top of nacelle 1 or the connecting unit to detect changes in wind direction in real time. The detected wind direction signal is transmitted to the yaw control system. The yaw control system calculates the angle to be adjusted based on the received wind direction signal and sends an instruction to the yaw actuator. The yaw actuator drives the yaw bearing to rotate according to the instruction of the control system, thereby adjusting the direction of nacelle 1 and wind turbine 2 to the new wind direction. Once wind turbine 2 is adjusted to the correct direction, the yaw brake exerts a braking force, stabilizing nacelle 1 in the new position.

[0036] In one embodiment of the present invention, the yaw control angle of the yaw system can be between -20° and 20°. For example, the yaw system can adjust the nacelle 1 and / or the wind turbine 2 if the angle to be adjusted is calculated in the range of -20° to 20° so that the wind turbine 2 can be adjusted in the correct direction.

[0037] In one embodiment of the present invention, every two cylindrical floating bodies 4 can be connected to each other by a truss structure or a support frame.

[0038] In one embodiment of the present invention, the plurality of cylindrical floating bodies 4 may each be connected to the anchoring points 5 via support rods, as shown in Fig. 1. By way of example, it may be that all of the cylindrical floating bodies 4 are each fixedly connected to the anchoring points 5 via the support rods, or it may be that some of the cylindrical floating bodies 4 are each fixedly connected to the anchoring points 5 via the support rods, and the embodiment of the present invention is not limited in this respect.

[0039] Anchoring point 5 may refer to a connection point for securing and stabilizing the floating wind turbine. The anchoring system connects the floating wind turbine to the seabed or other fixed structures via anchoring points 5 to withstand environmental stresses such as wind, waves, currents, etc., and to ensure the stability and safety of the floating wind turbine.

[0040] The anchoring system may include the following structures: a mooring cable: the mooring cable is a rope or chain that connects the floating wind turbine to the seabed or other fixed structures; the mooring cable is usually made of high-strength materials such as steel ropes, synthetic fiber cables (e.g. polyester, nylon) or composite cables; a mooring system: the mooring system is the fixed end of the mooring cable on the seabed and can be a gravity anchor, a suction anchor, a pile anchor or another type of anchor; the design of the mooring system depends on the geological conditions of the seabed and the environmental stresses; an anchoring point 5: anchoring point 5 is a specific location on a floating wind turbine to which the anchoring cable is attached; anchoring point 5 is typically designed to withstand high tensions and dynamic loads to ensure a reliable connection of the anchoring cable; a tensioning system: the anchoring system may also include a tensioning system that allows the tensioning force of the anchoring cable to be adjusted to different environmental conditions and displacements of the floating wind turbine.

[0041] In one embodiment of the present invention, as shown in Fig. 2, the anchoring point 5 can be located on the windward side or the upstream side.

[0042] In practice, a floating wind turbine generates a drift force toward the leeward or downstream side when exposed to wind or current. By locating anchor point 5 on the upwind or upstream side, the tension force of the mooring cable can be utilized to resist such drift forces, thus reducing the lateral movement of the floating wind turbine.

[0043] Furthermore, wind and currents often create asymmetric loads on the floating wind turbine, especially when wind and current speeds vary. By locating anchor point 5 on the upwind or upstream side, the mooring cable can be made to evenly distribute the load on the floating wind turbine, thus avoiding local overloading and improving overall stability.

[0044] In addition, the tension force of the mooring cable can generate a restoring force, which helps the floating wind turbine return to an equilibrium position after an external disturbance. When anchoring point 5 is located on the upwind or upstream side, the restoring force of the mooring cable can be maximized and the floating wind turbine's ability to withstand external disturbances can be improved.

[0045] The floating wind turbine will generate cyclical movements under the influence of wind, waves, and currents, which can lead to fatigue damage to the mooring cable and the floating wind turbine. By optimizing the position of the anchor points 5, unwanted oscillations and vibrations can be reduced, extending the service life of the mooring system and the floating wind turbine.

[0046] Offshore environmental conditions (e.g. wind direction, current velocity) can constantly change, and if the mooring point 5 is located on the windward or upstream side, the mooring system can better adapt to these changes to maintain the stability of the floating wind turbine.

[0047] In some feasible embodiments, if the offset angle is too large, it may not be possible to adjust the angle of the wind turbine 2 using the yaw system alone; therefore, the floating wind turbine provided by the embodiment of the present invention may further comprise spoilers 6 and a drive.

[0048] The spoiler 6 can be arranged along the circumferential direction of the cylindrical floating body 4, wherein the spoiler 6 is connected to the cylindrical floating body 4 via a bearing; and wherein the spoiler 6 can rotate around the cylindrical floating body 4 to adjust the angle of the floating wind turbine and thus adjust the angle of the wind turbine 2.

[0049] In particular, the spoilers 6 may be connected to the drive; when it is detected that the deviation of the angle of the wind turbine 2 from the current wind direction exceeds -20° to 20°, the drive may control the spoilers 6 to rotate in order to adjust the angle of the floating wind turbine and thus adjust the angle of the wind turbine 2.

[0050] In one embodiment of the present invention, the spoilers 6 can be arranged uniformly along the circumferential direction of the cylindrical floating bodies 4.

[0051] In some feasible embodiments, the spoiler 6 may also be a retractable structure that is driven by the drive to retract into the cylindrical float 4 when not in use and driven by the drive to protrude from the cylindrical float 4 when in use, the embodiment of the present invention not being limited in this respect.

[0052] In one embodiment of the present invention, the floating wind turbine is a leeward turbine. In particular, a leeward turbine may refer to a wind turbine in which the wind turbine 2 is designed to rotate downstream of the wind direction. Compared to a conventional upwind turbine, the wind turbine 2 of the leeward turbine is located on the downwind side of the nacelle 1, i.e., the wind first blows through the support structure 3 before reaching the wind turbine 2.

[0053] Features of the leeward turbine: One potential advantage of the leeward turbine is the natural yaw effect. Because the wind turbine 2 is located on the downwind side of the tower, the wind turbine 2 naturally follows the wind direction, reducing the need for an active yaw system. This can simplify the turbine's control system and reduce maintenance costs. In a leeward turbine, the tower can provide some protection for the wind turbine 2, reducing the direct wind load on the wind turbine 2. This can help reduce fatigue damage to the wind turbine 2 and extend its service life. The wind turbine 2 in the leeward turbine may respond dynamically faster to changes in wind speed because the wind turbine 2 is directly exposed to the changing wind speed. This may require more complex control strategies to manage the rotation speed and power output of the wind turbine 2.

[0054] In one embodiment of the present invention, the floating wind turbine comprises a nacelle 1, a wind turbine 2, a support structure 3, a yaw system, and a plurality of cylindrical floating bodies 4; wherein the nacelle 1 is connected to the wind turbine 2; and wherein the nacelle 1 is connected to the plurality of cylindrical floating bodies 4 via the support structure 3; and wherein the support structure 3 comprises a plurality of connecting units; and wherein two ends of one of the plurality of connecting units are each perpendicularly connected to the nacelle 1 and the corresponding cylindrical floating body 4, and wherein two ends of the other connecting units are each connected to the nacelle 1 and the corresponding cylindrical floating body 4, and wherein the other connecting units enclose an angle θ° with the nacelle 1 and the corresponding cylindrical floating body 4; where 0<θ°<90° orwhere 0<θ°<90°; and wherein the yaw system is used to adjust the angle of the wind turbine 2 and / or the nacelle 1. The embodiment of the present invention allows for the placement of a wind turbine at sea.

[0055] And through the unique support structure 3, in which two ends of one of the connecting units are each perpendicularly connected to the nacelle 1 and the corresponding cylindrical floating body 4, direct vertical support can be provided, which can help transmit and distribute vertical loads, such as the weight of the nacelle 1 and the wind turbine 2. Two ends of the other connecting units are each connected to the nacelle 1 and the corresponding cylindrical floating body 4, wherein these connecting units form an angle θ° with the nacelle 1 and the corresponding cylindrical floating body 4; where 0<θ°<90° and where 0<θ°<90°, respectively; such inclined connecting units provide additional structural support, which can help resist the lateral forces and torques and improve the stability of the entire structure.

[0056] In addition, a yaw system is arranged which can adjust the angle of the wind turbine 2 when the angle of the wind turbine 2 in the floating wind turbine does not match the wind direction, so as to ensure that the wind turbine 2 always faces the wind direction, thereby maximizing the efficiency of wind energy generation.

[0057] With reference to Fig. 3 illustrates a flowchart of steps of using a floating wind turbine in an embodiment of the present invention, wherein the floating wind turbine comprises a nacelle, a wind turbine, a support structure, a yaw system, spoilers, and a plurality of cylindrical floats; and wherein the nacelle is connected to the wind turbine; and wherein the nacelle is connected to the plurality of cylindrical floats via the support structure; and wherein the support structure comprises a plurality of connecting units; and wherein two ends of one of the plurality of connecting units are each connected perpendicularly to the gondola and the corresponding cylindrical floating body, and wherein two ends of the other connecting units are each connected to the gondola and the corresponding cylindrical floating body, and wherein the other connecting units enclose an angle θ° with the gondola and the corresponding cylindrical floating body; where 0<θ°<90° or where 0<θ°<90° applies; and wherein the yaw system is used to adjust the angle of the wind turbine; and wherein the spoilers are arranged along the circumferential direction of the cylindrical floating bodies; and wherein the spoilers are connected to the cylindrical floating bodies via a bearing, and wherein the spoilers are or can be telescopic relative to the cylindrical floating body; and wherein the spoilers are connected to the drive.

[0058] The control of the floating wind turbine can include the following steps: Step 301: Determine the current wind direction; In practice, the current wind direction of the environment in which the floating wind turbine is located can be detected by a sensor (such as a wind vane) in the yaw system; Step 302: Control the spoilers to adjust the angle of the wind turbine when the current wind direction does not match the current angle of the wind turbine. After detecting the current wind direction, it can be judged whether the current wind direction is consistent with the current angle of the wind turbine; if the current wind direction is inconsistent with the current angle of the wind turbine, an instruction can be sent to the drive to control the spoiler to adjust the angle of the wind turbine so that the wind turbine always faces the wind direction to maximize the efficiency of wind energy generation.

[0059] In the embodiment of the present invention, the current wind direction is detected; if the current wind direction does not match the current angle of the wind turbine, the spoiler is controlled to adjust the angle of the wind turbine. This embodiment of the present invention allows the angle of the wind turbine to be adjusted when the angle of the wind turbine in the floating wind turbine does not match the wind direction, ensuring that the wind turbine always faces the wind direction, thereby maximizing the efficiency of wind energy generation.

[0063] In the embodiment of the present invention, the current wind direction is detected; if the current wind direction does not match the current angle of the wind turbine, the spoiler is controlled to adjust the angle of the wind turbine. This embodiment of the present invention allows the angle of the wind turbine to be adjusted when the angle of the wind turbine in the floating wind turbine does not match the wind direction, ensuring that the wind turbine always faces the wind direction, thereby maximizing the efficiency of wind energy generation.
