Technical Field

[0002] As offshore wind power develops towards deep sea, floating foundations are gradually applied to offshore wind farms in deepwater areas.

There are a plurality of traction mechanisms 3, and at least one traction mechanism 3 is arranged on each mooring pile 2. The traction line 4 can be connected between the traction mechanism 3 and the floating foundation 6, and the traction mechanism 3 can tighten or loosen the traction line 4.

[0059] During use of the floating foundation seating device of the embodiment of the utility model, the suction cylinder base 1 can be installed on the seabed mud surface, and the mooring pile 2 can be connected to the floating foundation 6 through the traction mechanism 3 and the traction line 4, so that the floating foundation 6 is positioned above the suction cylinder base 1, thereby ensuring that the floating foundation 6 can be basically in a stationary state after seating, and can avoid the collision between the floating foundation 6 and the wind turbine during the installation of the wind turbine. At the same time, the suction cylinder base 1 can also avoid the problem that the floating foundation 6 is difficult to seat on soft soil and uneven foundations, and is easy to disassemble and assemble.

[0060] Therefore, the floating foundation seating device of the embodiment of the utility model can seat the floating foundation 6 in areas with certain winds and waves, such as in anchorages outside deep-water docks, without the need for installation at the deep-water dock, which can reduce the reliance on the deep-water dock when installing the wind turbine.

[0061] The traction mechanism 3 is preferably but not limited to a winch. The floating foundation 6 is preferably but not limited to an offshore wind turbine foundation. The floating foundation 6 is connected by a winch to accurately position the floating foundation 6 on the underwater suction cylinder support 1, and to facilitate the control of the stability of the floating foundation 6 after it is seated.

[0062] There are multiple mooring piles 2, for example, Figure 4In the illustrated embodiment, the number of mooring piles 2 is four, and they are arranged at intervals around the suction cylinder base 1, so that the traction mechanism 3 can easily adjust the angle and position of the floating foundation 6.

When the floating foundation 6 sinks to the vicinity of the suction cylinder support platform 1, the clamping mechanism can be switched to the clamping state, so that the plurality of columns 601 of the floating foundation 6 can be accurately limited to the designed positions of the suction cylinder support platform 1, respectively, so as to avoid the need to consider the excessive deviation of the contact position between the floating foundation 6 and the support platform when designing the suction cylinder support platform 1, resulting in an increase in the amount of steel used in the suction cylinder support platform 1.

[0066] In an optional embodiment, the clamping mechanism includes a plurality of linear drive mechanisms 7 arranged at intervals along the circumference of the suction cylinder 101, the linear drive mechanism 7 is arranged on the upper end surface of the suction cylinder 101, and the power output end extends toward the axis of the suction cylinder 101. In the clamping state, the power output end of the linear drive mechanism 7 can extend and abut against the side wall of the column 601.

[0068] In one embodiment, the suction cylinder support platform 1 includes a plurality of suction cylinders 101. The plurality of suction cylinders 101 are suitable for forming a triangle, and the guide structure 5 is arranged at a first side of the triangle and between two adjacent suction cylinders 101.

[0069] When the floating foundation 6 moves to the top of the suction cylinder base 1 under the traction of the traction mechanism 3 , the floating foundation 6 can first collide with the guide structure 5 , and then accurately fall to the top of the suction cylinder base 1 under the guidance of the guide structure 5 .

[0070] Preferably, in this embodiment, if Figure 7 As shown, the bottom surface of the floating foundation 6 is triangular and includes three columns 601 respectively arranged at the triangular positions of the triangle. The suction cylinder base 1 correspondingly includes three suction cylinders 101. Each suction cylinder 101 is used to support under a column 601, so as to provide stable support for the floating foundation 6.

[0071] As a convertible embodiment, the bottom surface of the floating foundation 6 is a square and includes four columns 601 respectively arranged at the four corners of the square. The suction cylinder base 1 correspondingly includes four suction cylinders 101, and each suction cylinder 101 is correspondingly supported under a column 601.

[0072] As another optional implementation, the floating foundation 6 includes a plurality of columns 601 , and the suction cylinders 101 of the suction cylinder support platform 1 are arranged in a one-to-one correspondence with the plurality of columns 601 of the floating foundation 6 .

[0073] In one embodiment, there are multiple guide piles 501, and the multiple guide piles 501 are arranged at intervals along the length direction of the first side of the suction cylinder base 1, which can prevent the floating foundation 6 from tilting.

[0075] The first side of the suction tube support 1 is preferably located at the end of the movement path of the floating foundation 6.

[0076] In one embodiment, the diameter of the suction cylinder 101 is larger than the diameter of the column 601 of the floating foundation 6. This arrangement ensures that the area of ​​the suction cylinder base 1 is large enough so that the floating foundation 6 can be placed above the suction cylinder base 1.

[0077] In one embodiment, the floating foundation supporting device further includes a buffer pad wrapped around the outer circumference of the guide pile 501 , and the buffer pad can prevent the floating foundation 6 from being damaged when colliding with the guide structure 5 .

[0078] According to an embodiment of the present invention, on the other hand, a wind turbine assembly system is provided, comprising a floating foundation bottom-supporting device and a wind turbine installation vessel.

[0080] Next, the method of using the fan assembly system of the utility model is described:

[0081] First, the suction cylinder cap 1 is installed on the seabed mud surface, then mooring piles 2 are built around the suction cylinder cap 1, and the traction mechanism 3 pulls the floating foundation 6 to the top of the suction cylinder cap 1 through the traction line 4. At this time, the floating foundation 6 can collide with the guide pile 501. Then, the floating foundation 6 slowly dives and sits firmly on the suction cylinder cap 1 by injecting ballast water. Then the limiting structure extends and limits the floating foundation 6 on the suction cylinder cap 1, thereby ensuring that the floating foundation 6 is basically in a static state.

[0082] The wind turbine is then hoisted onto the floating foundation 6 by the wind turbine installation vessel. After the wind turbine assembly operation is completed, the limiting structure is retracted, thereby allowing the floating foundation 6 and the wind turbine to be towed into the wind farm for installation.

[0083] In one embodiment, the wind turbine installation vessel is a self-elevating platform vessel or a bottom-seated vessel. By such a configuration, it can be ensured that the wind turbine installation vessel used for hoisting the wind turbine is also in a stationary state, which can avoid collision with the floating foundation 6 during the wind turbine hoisting process.

[0084] In summary, the floating foundation device of the first aspect and the wind turbine assembly system of the second aspect of the utility model have the following advantages:

[0085] 1. Reduce the reliance on deep-water docks when assembling floating wind turbines and pontoons;

[0086] 2. Solve the problem that floating bodies are difficult to install on soft soil and uneven foundations;
