Description

Technical Field

[0001] The utility model belongs to the technical field of offshore wind power engineering, and in particular relates to a floating wind turbine shared anchor structure capable of improving sea area utilization. Background Art

[0002] Currently, amidst the rapid development of offshore wind power, offshore wind power development is nearing saturation, and expansion into deep and offshore waters has become a key direction for future offshore wind power development. In deep and offshore waters, the marine environment is complex, and wind turbine capacity is constantly increasing. Therefore, floating wind turbines have become a key structural form for wind power development. Currently, floating wind turbines utilize a traditional mooring system, where each floating wind turbine is individually connected to a mooring structure via an anchor chain. Therefore, when there are a large number of floating wind turbines, a large number of mooring structures are required, which increases the vertical sea area occupied by the wind turbines and, to a certain extent, wastes deep and offshore resources. These factors restrict the development of floating wind turbines and are not conducive to the further development of offshore wind power in deep and offshore waters. Utility Model Content

[0024] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] This utility model proposes a shared anchor structure for floating wind turbines that can improve sea area utilization. By tying the existing floating wind turbine's mooring chain to a single mooring anchor structure, several mooring chains are now tied to the same mooring anchor structure. Furthermore, the mooring chains of adjacent wind turbines can also be tied to each other's mooring anchor structures. This reduces the number of mooring anchors and the sea area occupied by the floating wind turbines without changing the wind turbine mooring stability. Suction cylinder anchors are also used to replace traditional anchor structures, shortening construction time through negative pressure sinking. Sharing a mooring anchor structure with several mooring chains, or even several floating wind turbines, can significantly reduce the anchoring costs of floating wind turbines.

[0026] See Figure 2 The utility model provides a floating wind turbine shared anchor structure capable of improving sea area utilization, comprising an anchor plate 1, an anchor hole 2, a rib plate 3 and an anchor 4;

[0027] Anchor 4 is a cylindrical structure with an open bottom. Depending on the actual soil conditions, longitudinal and transverse ribs may be provided inside to increase friction between anchor 4 and the soil. Anchor 4 may have shapes including, but not limited to, cylindrical and polygonal. Anchor 4 sinks into the seabed soil under its own weight and vacuum.

[0028] Multiple anchor plates 1 are installed in an array on top of the anchor 4, effectively connecting them to transmit force. Each anchor plate 1 can be internally provided with transverse and longitudinal reinforcement plates. The number and size of the reinforcement plates can be adjusted based on the structural load and the distribution of the wind turbine structure. If the load requirements are met, reinforcement plates may not be required. Ribs 3 are installed between adjacent anchor plates 1 to further enhance structural strength. The shape, thickness, and position of the ribs 3 can be adjusted based on the number and location of the anchor plates 1.

[0029] Each anchor plate 1 is provided with at least one anchor hole 2 for connecting to one end of an anchor chain IV. The anchor hole 2 is used to moor the anchor chain IV of the wind turbine directly above and the adjacent wind turbine, thereby achieving the purpose of sharing the anchoring structure for different wind turbines and different anchor chains. Specifically, the other end of the anchor chain IV is used to connect to the floating wind turbine foundation structure III; each anchor hole 2 of the same floating wind turbine shared anchor structure is connected to a different floating wind turbine foundation structure III through the corresponding anchor chain IV. Therefore, the anchor chain used for mooring the wind turbine directly above and the adjacent wind turbine. The number and position of the anchor holes 2 can be adjusted according to the position of the upper wind turbine.

[0030] As an implementation manner, the anchor hole 2 is an open hole structure of the anchor plate 1, or the anchor hole 2 is an external ear plate anchor hole connected to the anchor plate 1 in any direction.

[0031] The materials of the shared anchor structure of the entire floating wind turbine include but are not limited to steel structure, concrete structure and new materials.

[0032] See Figure 1 , which is a use scenario of the floating wind turbine shared anchor structure provided by the utility model to improve the utilization rate of sea area. Figure 1 It can be seen that the structure of each floating wind turbine includes a floating wind turbine structure I, a floating wind turbine tower II, a floating wind turbine foundation structure III and an anchor chain IV; wherein, the floating wind turbine structure I is installed on the top of the floating wind turbine tower II, and the bottom of the floating wind turbine tower II has multiple floating wind turbine foundation structures III, each floating wind turbine foundation structure III is used to connect to one end of the anchor chain IV, and the other end of the anchor chain IV is connected to the anchor hole 2 of the floating wind turbine shared anchor structure. Figure 1 As an example, each floating wind turbine has three floating wind turbine foundation structures III distributed in a triangle. The three floating wind turbine foundation structures III can be dispersedly connected to the anchor holes 2 of the shared anchor structure of multiple floating wind turbines through three anchor chains IV, thereby enhancing the stability of the anchoring system.

[0033] As for a floating wind turbine shared anchor structure, it has multiple anchor holes 2, which are connected to the floating wind turbine foundation structures III of multiple floating wind turbines through multiple anchor chains IV. Therefore, multiple floating wind turbines can be anchored through a floating wind turbine shared anchor structure, reducing the footprint of the anchoring system.

[0034] The utility model provides a floating wind turbine shared anchor structure that can improve sea area utilization and has the following advantages:

[0035] 1) By tying multiple anchor chains to one anchoring structure, the footprint of the anchoring system is reduced, the vertical sea area occupied by the wind turbine is reduced, and the sea area utilization rate for deep-sea offshore wind power development is improved.

[0036] 2) The anchor chain of the wind turbine is tied to the adjacent anchor structure, which enhances the stability of the anchor system while ensuring safety.

[0037] 3) The anchoring structure is replaced by one instead of multiple ones, which reduces the cost of the anchoring structure and greatly shortens the construction time, thus greatly reducing the cost of the floating wind turbine foundation.

[0038] 4) The lower anchor adopts a cylindrical structure. During construction, it can sink to a certain depth by the deadweight of the anchoring structure. Finally, the suction anchor can be sunk into the soil by pumping negative pressure, effectively solving the problem of deep sea piling difficulties.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be considered within the scope of protection of the present invention.
