Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, specifically a vertical axis micro wind turbine. Background Technology

[0002] Wind turbines are power devices that use wind power as a mechanical energy source to convert mechanical energy into electrical energy. Based on different structural types, current wind turbines can be divided into horizontal axis wind turbines and vertical axis wind turbines. The rotor axis of a vertical axis wind turbine is perpendicular to the ground or the direction of airflow. It does not need to face the wind when the wind direction changes, which is a major advantage over horizontal axis wind turbines. It not only simplifies the structural design, but also reduces the gyroscopic force on the rotor when facing the wind.

[0003] In existing technologies, the blades of vertical axis wind turbines are often positioned at a fixed interval, and the blades are relatively close to the vertical axis, requiring greater wind force to drive the vertical axis to rotate, resulting in low wind energy utilization efficiency. Therefore, to solve the above problems, we need to design a vertical axis micro wind turbine. Utility Model Content
