Problems solved by technology

[0003] However, when wind turbines are subjected to complex wind, wave, and current loads, the yaw mode of wind turbines on offshore foundations has been difficult to meet the requirements for wind and dynamic optimization load performance, resulting in redundant mooring design, structural design and performance of wind turbines.

Embodiment Construction

[0029] Embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0030] It should be noted that when an element is “fixed” to another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terminology used herein in the descrip...

Abstract

The invention discloses an offshore foundation structure and an offshore wind turbine system; the offshore foundation structure comprises a floating body platform, wherein the floating body platform is provided with a ballast tank, and the ballast tank is used for adjusting the draft of the floating body platform; a switching platform which is arranged at one end of the floating body platform andis rotationally connected with the floating body platform; an anchor chain, wherein one end of the anchor chain is connected to the transfer platform, and the other end of the anchor chain is used forbeing connected with the seabed. The draft of the floating body platform is adjusted through the ballast tank, and the position of the switching platform is limited by the anchor chain so as to limitthe offshore foundation structure to be located in a specified area; the switching platform is rotationally connected with the floating body platform; the floating body platform can rotate around theswitching platform; when conditions such as different wind directions occur, the floating body platform can rotate around the switching platform equivalently, and therefore, self-adaptive adjustmentis conducted through the wind vane effect, the optimal balance with wind, waves, flow loads and the like is achieved, and a good environment is created for operation of a draught fan device.

Description

technical field [0001] The invention relates to the technical field of offshore wind power generation, in particular to an offshore infrastructure and an offshore wind turbine system. Background technique [0002] Faced with the growing global demand for clean and renewable energy, wind energy and wind power have become one of the most commercialized renewable energy sources and are showing a trend of vigorous development. Wind power projects are gradually moving from land to sea, from offshore areas to far seas area. [0003] However, when wind turbines are subjected to complex wind, wave, and current loads, the yaw mode of wind turbines on offshore foundations has been difficult to meet the requirements for wind and dynamic optimization load performance, resulting in redundant mooring design, structural design and performance of wind turbines. Decline. Contents of the invention [0004] Based on this, it is necessary to provide an offshore infrastructure and an offshor...
