Semi-submersible wind power generator platform with vibration reduction and isolation function

Abstract

The invention belongs to the related technical field of floating offshore wind power generators, and discloses a semi-submersible wind power generator platform with a vibration reduction and isolationfunction. The semi-submersible wind power generator platform comprises a supporting structure, a vibration reduction and damping assembly and a spherical hinge, wherein the supporting structure is ofan upper layer and a lower layer frame structure, and the upper layer of the supporting structure is connected with a generator assembly through the spherical hinge; the vibration reduction and damping assembly is connected with the generator assembly and the supporting structure, and is used for reducing vibration suffered by the generator assembly; the vibration reduction and damping assembly comprises a plurality of dampers and a plurality of springs, wherein the dampers are uniformly distributed around the generator assembly; and one ends of the dampers are connected to the supporting structure, and the other ends of the dampers are connected to the generator assembly through the springs. According to the semi-submersible wind power generator platform, the motion amplitude of an offshore wind power generator is can obviously reduced, so that the stability of the whole generator platform is increased, and a safe and reliable platform supporting infrastructure is provided for high-power floating offshore wind power generation equipment.

Description

technical field [0001] The invention belongs to the related technical field of floating offshore wind power generators, and more specifically relates to a semi-submersible wind power generator platform with vibration reduction and isolation functions. Background technique [0002] Due to the depletion of traditional energy sources in the past few decades, renewable energy sources, especially wind energy, have received more attention than ever before, and wind energy has been widely recognized for its important role in reducing greenhouse gas emissions. Development has experienced rapid growth over the past few decades. As wind power continues to grow rapidly around the world, because offshore wind resources have many special advantages over onshore wind energy, wind turbines, as wind energy collection devices, have developed from land to sea in recent years. However, as the water depth increases, the construction difficulty and cost of fixed-bottom offshore wind turbines in...
