Description

Technical Field

[0001] This utility model relates to the field of marine engineering technology, and in particular to a floating offshore wind turbine assembly platform. Background Technology

[0002] As the core equipment for deep-sea wind power development projects, the installation technology of floating offshore wind turbines directly affects the economic efficiency and safety of the projects. Traditional floating offshore wind turbines rely on large crawler cranes for high-level assembly at the dock, that is, lifting components such as the tower, nacelle, and blades one by one to a high position above the floating foundation for docking and installation.

[0003] The installation of traditional floating offshore wind turbines relies heavily on large crawler cranes, typically requiring only crawler cranes with a capacity of over 1,000 tons to meet operational requirements. Furthermore, the docks must possess extremely high load-bearing capacity. In reality, crawler cranes with a capacity of over 1,000 tons are scarce, and the number of docks meeting the operational conditions is very limited. In addition, installation requires lifting wind turbine components weighing hundreds of tons to a height of nearly 100 meters, making it highly susceptible to environmental factors such as wind speed and waves. Precise docking is extremely difficult, inefficient, and carries significant operational risks, resulting in a long assembly cycle for a single floating offshore wind turbine. Summary of the Invention

[0004] In view of the above problems, this application designs and provides a floating offshore wind turbine assembly platform.

[0022] This application designs and provides a floating offshore wind turbine assembly platform. A floating offshore wind turbine is a power generation device installed in deep-sea areas to capture wind energy and convert it into electrical energy.

[0023] like Figure 1 As shown, the floating offshore wind turbine assembly platform 1 is used to assemble the wind capture system 10 of the floating offshore wind turbine and install the assembled wind capture system 10 on the floating support system 20.

[0024] The wind capture system 10 is the core component of the floating offshore wind turbine, responsible for energy conversion. Specifically, the wind capture system 10 includes blades 11, a hub 12, a nacelle 13, and a tower 14. The blades 11 are typically arranged in groups of three, capturing wind energy through rotation to drive the generator. The hub 12 connects the blades 11, allowing the turbine to adapt to different wind speeds. The tower 14 is a tall steel structure that supports the blades 11. The nacelle 13 is mounted on top of the tower 14, and the generator is installed inside the nacelle 13. The nacelle 13 may also integrate power components such as gearboxes and transmissions.

[0025] like Figure 1 and Figure 2 As shown, the floating support system 20 provides stable support for the wind capture system 10, ensuring that the wind capture system 10 can float stably in the deep sea and avoid capsizing. For example, the floating support system 20 can use a tension leg type as its foundation to suit deep-sea applications. The floating support system 20 is connected to the seabed anchor block by anchor chains or cables. The anchoring system composed of anchor chains or cables is not the focus of this application and will not be described in detail here.

[0026] In this application, the floating offshore wind turbine assembly platform 1 is used to assemble floating offshore wind turbines in a modular manner. For example... Figure 1 As shown, the floating offshore wind turbine platform includes a modular platform body 30. The modular platform body 30 is the core structural component used to support the assembly and disassembly of the wind capture system 10. It serves as a basic framework, providing stability and scalability.

[0027] In some embodiments of this application, the assembled platform body 30 can be independently deployed in a designated sea area. In some embodiments of this application, the assembled platform body 30 can also be integrated into a dock. In other embodiments of this application, the assembled platform body 30 can also be integrated into an offshore platform, such as a wind power generation platform. In other embodiments of this application, the assembled platform body 30 can also be integrated into an engineering vessel.

[0028] Symmetrical wave-damping sections 31 are arranged on both sides of the main assembly platform 30. These wave-damping sections 31 extend outwards from the main assembly platform 30 to form a semi-enclosed installation area 32 on the sea surface. The floating support system 20 is located within this semi-enclosed installation area 32. The main assembly platform 30 and the symmetrically arranged wave-damping sections 31 together form a U-shape. The two wave-damping sections 31 effectively block the impact of wind, waves, currents, and tides on the assembly operation. The floating support system 20, located within the semi-enclosed installation area 32, reduces lateral impacts and improves assembly accuracy. The floating support system 20, as well as the assembled floating offshore wind turbine, can easily enter and exit through the opening in the semi-enclosed installation area 32. For example, the wave-damping section 31 is 300 meters long, 150 meters wide, and 15 meters deep.

[0029] A gantry crane 40 is mounted on the main assembly platform 30. The gantry crane 40 is fixed on a track 41, which is distributed along the main assembly platform 30 and the wave-damping section 31. The gantry crane 40 is suitable for high-precision and high-capacity lifting. A first clamping device 50 is mounted on the gantry crane 40. Specifically, the first clamping device 50 is rotatably mounted on the gantry frame 42 of the gantry crane 40. During operation, the first clamping device 50 can clamp one end of the tower cylinder 14 to form a fixed connection.

[0030] The assembly platform also includes a second clamp 60, which can clamp the other end of the tower 14 to form a fixed connection during operation.

[0031] In some embodiments of this application, the assembly platform further includes a drive module 70, which is disposed on the main body 30 of the assembly platform and located within the semi-enclosed installation area 32. The drive module 70 is connected to the second clamping device 60, and the drive module 70 extends and retracts to push the second clamping device 60, thereby rotating the tower 14 to the assembly position to assemble the wind capture system 10, or rotating the tower 14 to the insertion position to install the assembled wind capture system 10 onto the floating support system 20.

[0032] The assembly position is located on the gantry crane 40; in the assembly position, the tower 14 is in a horizontal state; the insertion position is located in the semi-enclosed installation area 32; in the insertion position, the tower 14 is in a vertical state.

[0033] In this application, the gantry crane 40 uses the gantry 42 as a fixed rotation axis. Under the coordinated action of the first clamping device 50, the second clamping device 60, and the drive module 70, one end of the tower 14 can rotate freely and be locked, thereby obtaining a stable assembly position. The blades 11, hub 12, and nacelle 13 are assembled at the assembly position. Similarly, a stable insertion position is also obtained to install the assembled wind capture system 10 onto the floating support system 20. Through the floating offshore wind turbine assembly platform 1, a low-level integrated assembly process and integrated installation flow can be realized, eliminating the need for large crawler cranes for high-level lifting. This effectively reduces dependence on special docks and lifting equipment, shortens on-site operation time, and reduces installation costs and safety risks, providing a new technical path for the efficient and safe installation of floating offshore wind turbines.

[0034] like Figure 4 As shown, an optional structure of the drive module 70 is further described below. The drive module 70 includes a telescopic arm 71, a linear drive device (not shown), and a tie rod unit 72. Specifically, the first end of the telescopic arm 71 is pivotally connected to the assembly platform body 30, the second clamping device 60 is fixedly disposed at the second end of the telescopic arm 71, the linear drive device is used to drive the telescopic arm 71 to extend and retract, and the tie rod unit 72 is used to drive the telescopic arm 71 to rotate.

[0035] The telescopic boom 71 combines linear telescopic and rotary motion, and can be adjusted between a generally horizontal direction and an inclined state. Exemplarily, the telescopic boom 71 may include multiple concentrically arranged telescopic units, each of which may be cylindrical or square, and the telescopic units are smoothly extended and retracted using slide rails, ball bearings, or threaded mechanisms. For example, in the telescopic boom 71, the telescopic unit closest to the assembly platform body 30 is fixed, and the remaining telescopic units can extend sequentially. The linear drive device can be an electric linear drive device, a hydraulic linear drive device, or a pneumatic linear drive device.

[0036] The pull rod unit 72 is used to apply force to drive the entire telescopic arm 71 to rotate. Specifically, the pull rod unit 72 includes a pull rod body 721. In some embodiments of this application, the pull rod body 721 is a rigid rod. In other embodiments of this application, the pull rod body 721 may also be a flexible structure (e.g., a steel cable or chain).

[0037] Taking a rigid member as an example, the first end of the tie rod body 721 is pivotally connected to the telescopic arm 71, and the second end of the tie rod body 721 is pivotally connected to the assembly platform body 30. The tie rod body 721 is connected to the upper part of the telescopic arm 71. When the tie rod unit 72 rotates relative to the assembly platform body 30, the telescopic arm 71 rotates around the pivot axis between the telescopic arm 71 and the assembly platform body 30, forming a certain tilt angle, further adjusting the angle of the tower 14 where the first clamping device 50 and the second clamping device 60 engage. The tie rod body 721 can be driven by a motor or a hydraulic cylinder to ensure that the rotation speed and rotation angle are controllable.

[0038] Specifically, the connection point where the first end of the pull rod body 721 pivots to the telescopic arm 71 forms a rotary joint, allowing the pull rod body 721 to move relative to the telescopic arm 71 during pulling without causing jamming. The connection point where the second end of the pull rod body 721 connects to the assembly platform body 30 forms another rotary joint, serving as an anchor point for the pull rod body 721 to ensure stable movement. The connection point between the first end of the telescopic arm 71 and the assembly platform body 30 ensures that the telescopic arm 71 can extend or retract independently without directly interfering with the movement of the pull rod body 721. The dual-pivot design of the pull rod body 721 allows the angle to be adjusted as needed during rotation, providing a more ideal movement trajectory, reducing impact and vibration, and effectively preventing jamming or overload. The pull rod body 721 can better adapt to changes in the length of the telescopic arm 71.

[0039] The following is for reference Figure 5 and Figure 6 The structure of the first clamping device 50 and the second clamping device 60 provided in some embodiments of this application will be described.

[0040] The first clamping device 50 includes a first upper jaw 51 and a second upper jaw 52. The first upper jaw 51 is U-shaped or semi-circular, and the second upper jaw 52 is also U-shaped or semi-circular, with the first upper jaw 51 and the second upper jaw 52 symmetrically arranged. The first clamping device 50 also includes an upper push rod 53, which is connected to the first upper jaw 51 and the second upper jaw 52 respectively. When the upper push rod 53 extends, it pushes the first upper jaw 51 and the second upper jaw 52 to open; when the upper push rod 53 retracts, the first upper jaw 51 and the second upper jaw 52 close, clamping the upper end of the tower cylinder 14. The power source for the upper push rod 53 can be provided by an electric motor, a pneumatic cylinder, or a hydraulic cylinder. The upper push rod 53 moves linearly, further driving the first upper jaw 51 and the second upper jaw 52 to rotate along their respective pivots, increasing the clamping gap, thereby preparing to clamp the upper end of the tower cylinder 14. When the upper push rod 53 retracts, the first upper jaw 51 and the second upper jaw 52 close, clamping the upper end of the tower 14. The inner curvature of the first upper jaw 51 and the second upper jaw 52 matches the diameter of the upper end of the tower 14. The stroke of the upper push rod 53 is adjustable, allowing the first clamping device 50 to flexibly adapt to different wind turbine tower 14 sizes.

[0041] The second clamping device 60 includes a first lower jaw 61 and a second lower jaw 62. The first lower jaw 61 is U-shaped or semi-circular, and the second lower jaw 62 is also U-shaped or semi-circular, with the first lower jaw 61 and the second lower jaw 62 symmetrically arranged. The second clamping device 60 also includes a lower push rod 63, which is connected to the first lower jaw 61 and the second lower jaw 62 respectively. When the lower push rod 63 extends, it pushes the first lower jaw 61 and the second lower jaw 62 to open; when the lower push rod 63 retracts, the first lower jaw 61 and the second lower jaw 62 close, clamping the lower end of the tower cylinder 14. The power source for the lower push rod 63 can be provided by an electric motor, a pneumatic cylinder, or a hydraulic cylinder. The lower push rod 63 moves linearly, further driving the first lower jaw 61 and the second lower jaw 62 to rotate along their respective pivots, increasing the clamping gap, thereby preparing to clamp the lower end of the tower cylinder 14. When the lower push rod 63 retracts, the first lower jaw 61 and the second lower jaw 62 close, clamping the lower end of the tower 14. The inner curvature of the first lower jaw 61 and the second lower jaw 62 matches the diameter of the lower end of the tower 14. The stroke of the lower push rod 63 is adjustable, allowing the second clamping device 60 to flexibly adapt to different wind turbine tower 14 sizes.

[0042] The first clamping device 50 and the second clamping device 60 can also adopt different clamping structures.

[0043] like Figure 3As shown, for ease of assembly, the tower 14 is horizontal in the assembly position. To maintain the horizontal position of the tower 14 and ensure even load distribution, a support plane 43 is formed on the top of the gantry 42 of the gantry crane 40. The support plane 43 extends horizontally and supports the tower 14 rotated to the assembly position or the wind capture system 10 held in the assembly position. A first clamp 50 is rotatably mounted on one side of the support plane 43. The drive module 70 pushes the second clamp 60 at the lower end of the tower 14, applying torque to rotate the tower 14 about the pivot axis between the first clamp 50 and the gantry 42 until it is approximately horizontal, i.e., in the assembly position. The support plane 43 forms another stable support point in the middle of the tower 14, facilitating assembly at the upper end of the tower 14. The first clamp 50 can be positioned in a slot in the middle of the gantry 42 to prevent it from reversing downwards towards the support plane 43.

[0044] A crawler crane 80 is also installed on the main assembly platform 30. The crawler crane 80 is used to assemble the wind capture system 10 at the assembly location. The crawler crane 80 can travel to different positions on the main assembly platform 30 on its own. The boom of the crawler crane 80 can extend or rotate, providing flexible adjustment angles. It can easily realize the assembly of multiple tower sections 14, or install the blades 11, hubs 12 and nacelles 13 on the upper end of the tower section 14.

[0045] The following is for reference only. Figure 7 To be continued Figure 12 This paper introduces the assembly process of a floating offshore wind turbine.

[0046] like Figure 7 As shown, one section of the tower 14 can be erected, or multiple sections of the assembled tower 14 can be erected. The gantry crane 40 starts and moves towards the wave-damping section 31 until the first clamping device 50 clamps the upper end of the erected tower 14, forming a stable connection. The gantry crane 40 drives the erected tower 14 further towards the wave-damping section 31. The second clamping device 60, driven by the drive module 70, extends upward and is located within the semi-enclosed installation area 32. The gantry crane 40 moves until the second clamping device 60 clamps the lower end of the erected tower 14, forming a stable connection, as shown. Figure 8 As shown. The drive module 70 extends further to push the second clamping device 60, causing the tower 14 to rotate upwards along the pivot axis between the first clamping device 50 and the gantry 42 to the assembly position. The entire tower 14 is located on the support plane 43, maintaining stability, as shown. Figure 9 As shown. At the assembly position, the crawler crane 80 assembles the wind capture system 10, for example, sequentially assembling other sections of the tower 14, hub 12, blades 11, and nacelle 13. At this time, the main frame of the wind turbine is assembled, as shown. Figure 10As shown. The drive module 70 further drives the second clamp 60 to retract, causing the tower 14 to rotate in the opposite direction along the pivot axis between the first clamp 50 and the gantry 42 to the insertion position. At this time, the tower 14 is in a vertical state, as shown. Figure 11 As shown. The gantry crane 40 continues to move towards the breakwater 31, installing the assembled wind capture system 10 onto the floating support system 20, for example, by directly plugging it into the foundation tower 14 on the floating support system 20, thus achieving the docking of the wind capture system 10 and the floating support system 20. Figure 12 As shown.

[0047] In this application, the first clamping device 50 is rotatably mounted on the gantry 42 of the gantry crane 40. The gantry 42 raises the lever support position, allowing for reversal with only a weight equal to that of the wind turbine. The inclusion of a drive module 70 enhances the precision of the reversal control. The insertion position allows for integrated docking with the floating support system 20, making it particularly suitable for scenarios where the floating support system is more than 20 meters from the shoreline, eliminating the need for a large crane for docking with the floating support system 20.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
