Embodiment Construction

[0043] In the past 10 years, China's wind power generation has developed rapidly, and its installed capacity has increased from 20,000 kilowatts in 1990 to 268,000 kilowatts in 1999. By 2010, China's wind power generation installed capacity has exceeded 5 million kilowatts. One of the countries with the most developed power generation.

[0044] In the south and southwest of my country, there are many mountains and hills, which bring great challenges to the transportation of long leaves. Therefore, it is one of the important methods to solve this problem to manufacture the blades in sections, transport them to the destination and then assemble them. In view of the large-scale blades, the continuous increase in power, the loads on the blades are also increasing, and the requirements for the mechanical properties of the materials and the weight of the blades are also getting higher and higher. The traditional fiberglass blades are molded to meet the aerodynamic shape requirements...

Abstract

The invention provides a blade, a wind driven generator and a cover mounting method. The blade is applied to the wind driven generator, and comprises a blade body (11), a cylinder (12), a connecting module (13) and multiple covers (14). The cylinder (12) is arranged in the blade body (11); the multiple covers (14) are connected to the cylinder (12) through the connecting module (13); and gaps are formed between the adjacent covers (14) in the extending direction of the blade body (11). The blade, the wind driven generator and the cover mounting method can reduce the load and the stress suffered by the covers, so that materials of the covers are more various, and the pneumatic appearance molding of the covers is simpler.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a blade, a wind power generator and a skin installation method. Background technique [0002] At present, the world's non-renewable energy sources tend to be exhausted, and the pollution caused by the burning of oil and coal has endangered the survival of human beings. The development and utilization of green energy has been paid more and more attention by various countries. At present, the wind power industry has begun a large-scale expansion in the world. [0003] With the development of large-scale wind power equipment, the design and manufacture of wind turbine blades, as the key components of wind energy capture, is facing more and more difficulties, especially as the power of wind turbines increases, the length of blades is getting longer and longer. Adopting the production method of the existing blades will bring problems in manufacturing process, material c...
