Buoyant table type offshore wind power foundation

Abstract

A buoyant table type offshore wind power foundation comprises a wind driven generator, a steel tower barrel, a foundation transition segment, a flange ring, a columnar foundation, supporting beams, an annular support, suction anchors, draining pumps and fixed mooring ropes. The foundation transition segment is arranged on the lower portion of the steel tower barrel, and the supporting beams are arranged on the periphery of the foundation transition segment to be connected with the columnar foundation. A closed cavity is formed in the columnar foundation, and a steel bin separation plate is arranged in the cavity for supporting. The annular support is arranged on the periphery of the columnar foundation, and the draining pumps are arranged between the annular support and the steel tower barrel and in the columnar foundation. The fixed mooring ropes are symmetrically arranged at the four points of a columnar foundation platform and are fixedly restrained on a seabed foundation bed through the suction anchors. The buoyant table type offshore wind power foundation has the beneficial effects that better buoyancy and stronger wind and wave resisting capacity are achieved, and therefore it is guaranteed that the buoyant table type offshore wind power foundation safely and stably operates in deep and open sea areas.

Description

technical field [0001] The invention relates to a floating platform offshore wind power foundation structure, which can lower and stabilize the center of gravity of the floating foundation, thereby improving the stability of the offshore floating wind power structure. Background technique [0002] Offshore wind power resources are abundant and have many advantages that land wind power cannot match. Offshore wind power development has now become a hot spot and frontier of global new energy development. In sea areas with a water depth greater than 50m, the wind speed is stable and the wind shear is small, which has the unique advantages of wind power generation. However, the pile foundation or gravity foundation usually used by wind turbines in offshore sea areas is not suitable for application in sea areas with large water depths. , so the wind power generation equipment in this sea area needs to adopt floating foundation. At the same time, compared with offshore waters, the...

Problems solved by technology

In sea areas with a water depth greater than 50m, the wind speed is stable and the wind shear is small, which has the unique advantages of wind power generation. However, the pile foundation or gravity foundation usually used by wind turbines in offshore sea areas is not suitable for application in sea areas with large water depths. , so the wind power generation equipment in this sea area needs to adopt floating foundation

At the same time, compared with offshore waters, the working environment of offshore wind turbines in deep sea areas is harsh, and the loads they suffer include the combined effects of complex and changeable environmental loads such as wind, waves and currents, which will undoubtedly affect the safety design and operational stability of offshore floating wind turbines. bring great challenges
