[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] This invention provides an auxiliary device and method for installing a floating wind turbine, such as... Figure 1-6 As shown, it includes a pontoon 1 and a positioning device 5 for fixing the floating structure. The pontoon 1 is preferably made of steel. The interior of the pontoon 1 is hollow and sealed. The pontoon 1 has the function of floating in the water. A fixing column 2 is fixedly connected to the top of the pontoon 1. The fixing column 2 is made of steel and welded to the fixing column 2. A connecting crossbar 3 is fixed to the outer surface of the fixing column 2. The connecting crossbar 3 is a steel pipe or truss steel structure to increase stability.

[0034] like Figure 1-3 As shown, a central connector 4 is fixedly connected to the end of the connecting crossbar 3 away from the pontoon 1. The central connector 4 is cylindrical in shape, closed at the top, hollow inside, and open at the bottom to facilitate the installation of the positioning device 5. The positioning device 5 is installed inside the central connector 4. When the fixing rope 505 on the positioning device 5 is tightened, the floating foundation structure can be submerged and positioned to reduce the shaking caused by wind and waves on the floating foundation structure and facilitate the installation of components on the floating foundation. A fixed base 8 is welded and fixed to the top of the central connector 4. A connecting flange base 9 is fixedly connected to the top of the fixed base 8.

The connecting device 6 can be fixed to the floating foundation to effectively reduce the swaying of the floating foundation caused by waves. A track device 7 for vertical movement of the floating wind turbine base is connected to the connecting device 6. The connecting device 6 and the track device 7 are connected to the hull to reduce the relative swaying between the floating foundation components and the hull, and effectively facilitate the lifting of the assembled structure by the crane on the hull, which is beneficial to the installation of the floating foundation, the column and the unit.

[0036] like Figure 4 As shown, the positioning device 5 includes a locking motor 501, a transmission rod 502, a take-up roller 503, a connecting pulley 504, and a fixing rope 505.

The openings of the second clamp 607 and the first clamp 606 are fixed by clamping bolts 608.

[0038] like Figure 5 As shown, clamp 2 607 and clamp 1 606 are combined to form a ring. The combination of clamp 2 607 and clamp 1 606 can be sleeved with the fixed post 2. The combination of clamp 2 607 and clamp 1 606 can facilitate the connection and fixation with the fixed post 2, effectively improving the stability of the connection.

The track plate 701 is welded to the top plate 702, the bottom of the top plate 702 is fixed to the hydraulic telescopic rod 703 by bolts, the telescopic end of the hydraulic telescopic rod 703 is fixed to the top of the positioning base 609 by bolts, the back of the track plate 701 is welded to the connecting bracket 706, the hull connector 707 is welded to the connecting bracket 706, the connecting hole 708 is opened on the surface of the hull connector 707, and the hull connector 707 is fixed to the hull through the connecting hole 708 and bolts, so that the connecting device 6 and the floating foundation structure can be connected to the hull.

[0040] The hull, connecting device 6, track device 7, and floating foundation are connected and fixed to form an integrated connection to avoid relative displacement, reduce the relative displacement between the hull and components, and effectively improve installation accuracy.

[0045] S2: Connect the three sets of fixing ropes 505 to the fixed foundation structure at the bottom of the water body through the connecting pulleys 504 or anchor them. The rotation of the locking motor 501 can drive the take-up roller 503 to rotate and tighten the fixing ropes 505. Tightening the fixing ropes 505 reduces the impact of wind and waves on the floating structure and reduces the swaying of the structure.

[0046] S3: After the fixing rope 505 is tightened, the foundation structure above the center connector 4 will begin construction and installation;

[0047] S4: After the foundation structure above the center connector 4 is installed, adjust the tension of the fixing rope 505 to a relaxed state, connect the hull to the hull connector 707 and move the positioning ring 601 to the top of the fixing column 2.
