Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a tower connection structure of a wind power generator. Background Art

[0002] Wind is a new energy source with great potential. In the early 18th century, a violent gale swept across England and France, destroying 400 windmills, 800 houses, 100 churches, more than 400 sailboats, injuring thousands of people, and uprooting 250,000 trees. Just in the case of uprooting trees, the wind produced 10 million horsepower (7.5 million kilowatts; one horsepower equals 0.75 kilowatts) of power in a few seconds! It has been estimated that the wind resources available for power generation on Earth are about 10 billion kilowatts, almost 10 times the current global hydropower generation. At present, the energy obtained from burning coal in the world each year is only one-third of the energy provided by wind power in a year. Therefore, both at home and abroad, great importance is attached to using wind power to generate electricity and develop new energy.

[0003] With the development of science and technology, the capacity of wind turbine generator sets is increasing, and the technical requirements for wind turbine towers are also gradually increasing. The wind turbine towers produced are generally composed of multiple cylinders welded together, which can improve the overall strength, but make the installation of the tower inconvenient to operate. During installation, the cylinders need to be lifted to the installation position one by one by a crane for welding, and the connection method between the cylinder and the base is relatively simple, which cannot bear a large radial load on the axis. Therefore, a wind turbine tower connection structure is proposed. Utility Model Content
