Problems solved by technology

The single-column foundation structure is suitable for offshore wind power generation systems with a high center of gravity. Due to the small waterline area and large draft, it is also conducive to improving the overall performance of floating wind turbines in deep waters. However, the main body length of the single-column foundation structure is too long. If a single-column foundation structure is used for each generator set, it will be difficult to construct and install, and the stability will be poor in strong winds

Abstract

The invention discloses a strong wind resistant offshore wind turbine generator set and installation method. The strong wind resistant offshore wind turbine generator set comprises a central stand column and edge short stand columns, wherein an underwater bracket is arranged on the surface of the central stand column, and a first fixing ring is arranged at one end of the underwater bracket; secondfixing rings are arranged on the surfaces of the edge short stand columns, floating bases are arranged at the tops of the edge short stand columns, tower rods are arranged at the tops of the floatingbases, and electric generators are arranged at the tops of the tower rods; wind wheels are arranged on one sides of the electric generators, and first steel wire ropes are arranged between the top and bottom of the edge short stand columns and the central stand column. According to the strong wind resistant offshore wind turbine generator set and the installation method, by arranging the centralstand column, the edge short stand columns, the underwater bracket, the first fixing ring, the second fixing rings, the floating bases and the first steel wire ropes, the cost is saved, the contact area with the sea surface is increased by the floating bases, and the strong wind resistance capability of the wind turbine generator set is improved.

Description

technical field [0001] The invention relates to the technical field of offshore wind power equipment manufacturing, in particular to a strong wind-resistant offshore wind generator set and an installation method. Background technique [0002] With the gradual saturation of the development of wind power resources in intertidal and offshore areas and the gradual increase in energy demand, it is an inevitable trend for offshore wind power generation to move from intertidal and offshore areas to deep-sea areas. The resource reserves of deep-sea wind power in my country ranks among the top in the world, and the development prospect of the offshore wind power industry is broad. Compared with shallow-sea wind farms, deep-sea wind farms have the advantages of high wind speed, low wind shear, and less turbulence, and have less impact on the sea channel. With the increase of water depth, the basic structure of traditional fixed offshore wind turbines has been difficult to meet the re...
