Background

The available resources on the earth are gradually reduced, and the environmental protection consciousness is gradually increased today, and the utilization and development of renewable energy are gradually paid more attention from various countries due to the characteristics of clean renewable energy and gas emission in a low-temperature chamber. Among them, solar power generation and wind power generation are most important.

Wind power generators are classified by the direction of the rotation axis of their impellers, and have two major types, horizontal axis and vertical axis. At present, horizontal shaft type wind driven generators are in the mainstream form in domestic and foreign markets. However, the horizontal axis wind turbine has a great disadvantage. Such as: the horizontal axis type wind driven generator is high in installation height, large in occupied space, poor in wind resistance, large in noise during operation and high in starting wind speed (generally more than 3.5 m/s), and a yaw system facing the wind is required. Compared with a horizontal shaft type wind driven generator, the vertical shaft type wind driven generator can adapt to any wind direction, is lower in installation height, can be arranged in a connected mode, and occupies small space; in addition, the installation center of gravity of heavy components (such as a generator and a gearbox) is low, and the overall stability and wind resistance are good; the noise generated by the generator is low when the wind turbine runs, and the starting wind speed is low (about 2 m/s). Therefore, in recent years, vertical axis wind turbines have been receiving more and more attention.

From the above, it can be seen that: under the condition of ensuring a sufficient wind area, how to ensure that the vertical blades of the vertical axis wind driven generator are stably arranged on the vertical axis is a key problem for designing, manufacturing and installing the blades of the vertical axis wind driven generator with larger power, and a better solution is not provided so far.
