Detailed Implementation

[0023] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0024] like Figures 1 to 6 As shown.

[0025] This application discloses a floating offshore wind power nearshore fixed wharf dual-unit integrated construction structure, comprising:

[0026] The lifting platform 4 consists of a platform deck 41 and platform legs 42. The platform legs 42 are fixedly connected to the seabed bearing layer. The inner sides of the platform legs 42 are fixedly reinforced by internal diagonal braces 44. The outer sides of the platform legs 42 are fixedly installed with anti-collision facilities 43 that provide elastic buffering. The anti-collision facilities 43 can be made of elastic rubber plates, etc.

[0027] A platform panel 12 is fixed at the diagonally opposite corner of the platform deck 41. The platform panel 12 extends outward from the side of the platform deck 41. The bottom of the platform panel 12 is reinforced by multiple spaced triangular supports 11. Each triangular support 11 has a hollow through-hole in the middle to allow sea breeze to pass through. The triangular supports 11 and the platform panel 12 constitute the extension platform 1.

[0028] The top surfaces of the two obliquely opposite platform panels 12 each have an impeller assembly 2, on which a combined impeller 3 is mounted. The combined impeller 3 consists of a hub 32 and three blades 31 mounted on the hub 32. The three blades 31 occupy a 270° plane on the outwardly cantilevered platform panel 12, avoiding encroachment on the central space of the platform deck 41.

[0029] The impeller assembly 2 includes a steel support 22 fixed to the top surface of the platform panel 12. The steel support 22 is reinforced and fixedly connected to the platform panel 12 by reinforcing ribs 21. A flange 23 is fixed on the steel support 22 to mate with the flange interface of the hub 32.

[0030] A crane 9 is installed on the platform deck 41 corresponding to the two diagonally opposite platform panels 12. A storage tower 81 and a storage cabin 82 are placed in the middle of the platform deck 41 below the crane 9.

[0031] The lifting platform 4 has transport barges 7 distributed along its sides for transporting the blades 31. The transport barges 7 are elastically cushioned and contact the anti-collision facilities 43 of the lifting platform 4. The lifting platform 4 also has mooring piles 6 along its sides, on which floating foundations 5 are moored. A wind turbine tower is installed on the floating foundation 5, and a crane 9 can lift the combined impeller 3 to the top of the wind turbine tower on the floating foundation 5 for installation.

[0032] The blade 31 is transported to the side of the lifting platform 4 by the transport barge 7. The transport barge 7 and the anti-collision facility 43 on the lifting platform 4 make elastic buffer contact, thereby avoiding hard contact and solving the problem of the transport barge being subjected to hard impact from sea waves on the offshore lifting platform.

[0033] This application discloses a construction method for a floating offshore wind power near-shore fixed wharf dual-unit integrated construction structure, comprising:

[0034] S1: Construct a fixed hoisting platform 4 in the nearshore waters with a depth of 20-30m. The platform legs 42 extend into the seabed bearing layer, and the platform deck 41 extends to a certain height above the water surface.

[0035] S2: An expansion platform 1 and an impeller assembly device 2 are added to the opposite corners of the hoisting platform 4 to form a new structure. Two new cranes 9 are added to the hoisting platform 4 to ensure that the cranes 9 on the hoisting platform 4 can cover the operation of the two impeller assemblies.

[0036] S3: Mooring piles 6 are driven on both sides of the hoisting platform 4. The two sides of the hoisting platform 4 are used to moor transport barges 7. The transport barges 7 and the anti-collision facilities 43 on the hoisting platform 4 make elastic buffer contact, thereby realizing the construction of a floating offshore wind power nearshore fixed wharf dual-unit integrated construction structure with elastic buffer contact between the transport barges 7 and the hoisting platform 4.

[0037] S4: The floating foundation 5 of the floating wind turbine is towed to the mooring pile 6 for mooring and fixation.

[0038] S5: Crane 9 completes the installation of combined impeller 3. Two cranes 9 successively install the wind turbine tower, nacelle, and impeller, ensuring that the blades and combined impeller 3 do not interfere with each other.

[0039] S6: After hoisting is completed, release the corresponding constraints, secure it, and tow it by tugboat to the wind farm design location.
