Description

Technical Field

[0001] This utility model relates to the field of wind turbine generators, specifically a static blade wind turbine generator. Background Technology

[0002] Wind turbines are devices that generate electricity using wind energy. Generally, the blades of traditional wind turbines rotate according to wind speed, thereby driving the generator to produce electricity. However, this traditional blade design has some problems. For example, when the wind speed is too high, the rotation speed of the blades will increase, which can easily lead to blade damage or generator failure, increasing maintenance costs. The rotation diameter of the blades is usually large, which not only occupies a lot of space but also generates a lot of noise pollution. In addition, the high-speed rotating wind turbine blades can also pose potential hazards to birds, people, or surrounding facilities. Utility Model Content
