[0002] With increasing awareness of the significant consumption and environmental pollution of traditional energy sources, countries around the world are scrambling to find pathways for energy transition. Wind energy, as the most technologically mature, scalable, and commercially viable renewable energy source, has garnered widespread attention and significant development. Although offshore wind power development began relatively late, it has experienced rapid growth in recent years, driven by the stability and high power generation capabilities of offshore wind resources. This has led to a booming offshore wind power operation and maintenance market. However, offshore wind power operation and maintenance is hampered by harsh natural environments, complex geographical locations, and difficult transportation. This results in low accessibility for personnel during operation and maintenance, and significant safety risks associated with personnel transfers. Consequently, the safety, reliability, and stability of offshore wind power operation and maintenance vessels have garnered significant attention.

The auxiliary motor 12 then stops moving. The upper cylinder 9 moves, driving the upper engaging frame 10 to move closer to the wind turbine C until the upper engaging frame 10 passes the wind turbine fixing rod D.

Example

[0051] Example 2 is basically the same as Example 1, except that:

[0052] A locking device for a ship against a wind turbine, wherein the upper meshing frame 10 and the lower meshing frame 14 have the same structure and size, and the upper meshing frame 10 and the lower meshing frame 14 are arranged in a mirror image; a limit switch 11 is provided at one end of the upper meshing frame 10, and the upper meshing frame 10 and the lower meshing frame 14 are engaged and connected via the limit switch 11.

[0053] The method for using the locking device for the ship against the wind turbine includes any one or any combination of the following operations:

[0054] Lateral compensation: When ship A moves laterally, after the force on the lateral adjustment screw 3 exceeds a predetermined value, the main motor 1 rotates, and the lateral adjustment screw 3 rotates, driving the upper engaging frame 10 and the lower engaging frame 14 to move laterally as a whole, thereby driving the rotating frame 7 to move laterally, and then driving the large bushing 20 to move laterally. A fixed frame 6 is fixedly connected to ship A. The large bushing 20 drives the fixed frame 6 to move laterally, and at the same time drives ship A to move laterally. At this time, ship A deviates laterally. When the lateral force is less than the predetermined value, the main motor 1 stops moving, and ship A completes the lateral motion compensation.

[0055] Longitudinal compensation: When ship A undergoes longitudinal movement, after the cylinder force exceeds a predetermined value, the upper cylinder 9 and the lower cylinder 13 move, driving the upper engaging frame 10 and the lower engaging frame 14 to move longitudinally as a whole, thereby driving the rotating frame 7 to move longitudinally, and then driving the large bushing 20 to move longitudinally. A fixed frame 6 is fixedly connected to ship A. The large bushing 20 drives the fixed frame 6 to move longitudinally, and at the same time drives the ship A to move longitudinally. At this time, ship A undergoes longitudinal deviation. After the cylinder force is less than a predetermined value, the upper cylinder 9 and the lower cylinder 13 stop moving, and ship A completes longitudinal motion compensation.

[0056] Vertical compensation: When ship A undergoes vertical movement, due to a certain gap between the upper meshing frame 10, the lower meshing frame 14 and the fan fixing rod D, the upper meshing frame 10 and the lower meshing frame 14 move vertically on the fan fixing rod D, thereby driving the rotating frame 7 to move vertically, and then driving the large bushing 20 to move vertically. The first fixing frame 6 is fixedly connected to the ship A. The large bushing 20 drives the first fixing frame 6 to move vertically, and at the same time drives the ship A to move vertically, so that the ship A can move freely up and down along the fan fixing rod D, achieving vertical compensation;

[0057] Roll compensation: When ship A rolls, a connecting seat 16 rotates along the large pin 17, thereby causing the transverse adjustment seat 15 to rotate with the large pin 17. The transverse adjustment seat 15 is set on a fixed frame 6 and fixedly connected to the ship A, thereby driving the fixed frame 6 and the ship A to roll, so that the ship A rotates synchronously with the top large pin 17 to achieve roll compensation;

[0058] Pitch compensation: When the ship A pitches, the rotating frame 7 rotates along the small pin 23, thereby driving the large bushing 20 and the transverse adjustment seat 15 to rotate. The transverse adjustment seat 15 is installed on the ship A along with a fixed frame 6, so that the ship A rotates synchronously with the small pin 23 to achieve pitch compensation;

[0059] Yaw compensation: When ship A pitches forward, a certain gap exists between the upper and lower meshing frames 10, 14, and the fan fixing rod D, allowing the upper and lower meshing frames 10, 14 to move vertically on the fan fixing rod D, thereby driving the rotating frame 7 to move vertically, and then driving the large bushing 20 to move vertically. Since the first fixing frame 6 is fixedly connected to ship A, the large bushing 20 drives the first fixing frame 6 to move vertically, which in turn drives the ship A to move, allowing ship A to compensate for pitching.

[0060] Compensation for dangerous working conditions: The rubbing operation of ship A is generally carried out in relatively calm weather. However, if an unexpected situation occurs and the wind and waves are too strong, when the compensation in one direction exceeds the limit, the auxiliary motor 12 rotates in the reverse direction, driving the upper engaging frame 10 and the lower engaging frame 14 to move in the reverse direction, thereby opening the closed upper engaging frame 10 and the lower engaging frame 14, so that a fixing frame 6 is separated from the fan fixing rod D to avoid accidental damage.

[0061] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
