Abstract

The invention belongs to the technical field of offshore wind power equipment, and particularly relates to a protection type offshore wind turbine generator. The protection type offshore wind turbinegenerator comprises a central stand column, a central floating base which is arranged at the top of the central stand column and a height sensor which is arranged on the sea surface, and further comprises a central counterweight seat, steel ropes, seabed fixing piles, first connecting rods, second connecting rods, third connecting rods, power generating units and a controller, wherein the controller is used for controlling the power generating units to work, the central counterweight seat is fixedly connected to the lower end of the central stand column and is used for keeping the central stand column vertical, and one ends of the steel ropes are arranged on the central stand column. According to the protection type offshore wind turbine generator, the plurality of power generating units are arranged, and meanwhile, contraction mechanisms, generators, blades and protective devices are matched with one another, so that when a huge wave comes, the generators and the blades can be protected in the protection devices, damage to the generator set is avoided, and the maintenance cost is saved.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power equipment, in particular to a protective offshore wind power unit. Background technique [0002] With the gradual saturation of wind power resources in the intertidal zone and offshore areas and the gradual increase in energy demand, it is an inevitable trend for offshore wind power to move from intertidal zones and offshore areas to deep sea areas. my country's deep-sea wind power resource reserves rank among the top in the world, and the offshore wind power industry has broad prospects for development. Compared with shallow sea wind farms, deep sea wind farms have the advantages of high wind speed, low wind shear, and low turbulence, and have less impact on sea lanes. With the increase of water depth, the basic structure of traditional fixed offshore wind turbines has been difficult to meet the requirements of deep sea wind energy development, and the dead weight and engineering cos...
