Abstract

The invention discloses an offshore wind turbine generator transportation method and an impeller assembly method thereof. The impeller assembly method comprises the steps that a hub is separated froma transportation tool and then hoisted to an assembly station of a platform deck; the hub is fixed to a hub support transfer plate; bolts and rubber rings are screwed into flange bolt holes; a variable-pitch debugging box is placed near the hub and connected to a variable-pitch motor through a power line and a control handle; a sealant is applied to blade root flanges of three blades, the three blades are hoisted by using a crane, the blade root flanges of the three blades are in contact with a hub blade root bearing flange, and then the three blades are connected to the hub; after the impeller is assembled, the variable-pitch debugging box is disassembled; and a hub front end outlet frame and a cover plate component are arranged, and the exposed bolts of the hub are sealed through the sealant. The installation process is simple, the operation is convenient, the assembly cost is low, and the working efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a method for transporting offshore wind turbines and an assembly method for impellers thereof. Background technique [0002] Wind power generation is the fastest growing green energy technology in the world. While the construction of land wind farms is developing rapidly, people have noticed some restrictions on the use of land wind energy, such as large area and noise pollution. Given the wind energy resources available and the viability of today's technology, the ocean becomes a rapidly growing wind power market. [0003] The impeller of the offshore wind turbine is mainly composed of a hub and three blades. There are many methods for assembling the impeller in the prior art, which can be mainly divided into onshore assembly methods and offshore hoisting methods. [0004] Offshore hoisting methods can be roughly divided into two types, one is to decompose the imp...
