Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine floating platforms, in particular to an offshore wind turbine floating platform structure. Background Art

[0002] A wind turbine floating platform is a basic structure used for offshore wind power generation. It is mainly designed to support wind turbines and ensure their stable operation in the marine environment. Unlike traditional onshore wind turbines, offshore wind turbines usually need to be installed in deep water areas, and floating platform technology makes this process more feasible.

[0003] Existing technologies include the utility model patent with publication number CN209654172U, which discloses a floating platform suitable for mounting multiple wind turbines. The patent includes a connecting assembly, a first fixing cylinder, a second fixing cylinder, a third fixing cylinder, and a first mounting cylinder and a second mounting cylinder for mounting the wind turbines. The first, second, first, and second mounting cylinders are arranged in an isosceles trapezoidal shape. The third fixing cylinder is located between the first and second mounting cylinders and is fixedly connected to the first, second, first, and second mounting cylinders via the connecting assembly. The connecting assembly, the first, second, third, first, and second mounting cylinders are all hollow structures, and ballast tanks are respectively provided within the first, second, third, first, and second mounting cylinders. The platform has excellent overall stability, can effectively resist external impacts, and can simultaneously mount more than two wind turbines, resulting in high operating efficiency.

There are four floating feet under the floating plate for support, which are then fixed to the fixed plate by a traction steel cable, so that it can be fixed at a certain position on the sea. When the floating plate supports the wind power generation equipment and puts it on the sea surface, the four floating feet will sink into the water, lowering the overall center of gravity. When the wind power generation equipment is subjected to marine environmental loads such as waves and currents, the four floating feet will also be affected by unequal forces, which will offset each other, thereby improving the overall stability of the wind power generation equipment and thus improving the anti-subversion ability of the wind power generation equipment. However, the wind power generation equipment and the floating plate are connected by several screws, and the screws need to be connected with the help of tools to screw the screws, which also makes the steps of installing the wind power generation equipment on the floating plate more troublesome, affecting the speed of installing the wind power generation equipment.
