Description

Vertical axis wind power generation impeller

Technical Field

The utility model relates to a vertical axis wind power generation technical field particularly, relates to a vertical axis wind power generation impeller.

Background

Wind energy is a source of clean energy and is the most promising new energy source. The wind power generation has no pollution, little influence on the environment and less land occupation, and along with the development of the wind power generation, the wind energy utilization rate is continuously improved, and the power generation cost is continuously reduced. The common horizontal-shaft three-blade generator in the middle of the mountain and the sea is too large in size, is mostly installed in remote mountainous regions and sea rivers, and has high requirement on wind direction and complex structure. Therefore, the manufacturing, installation, and maintenance costs are high.

The vertical axis wind driven generator has the greatest advantages that the vertical axis wind driven generator can start to generate electricity in breeze of 3 m/s (equivalent to 28m/s of high wind at the speed of 100km/h, 9 times of breeze), has simple structure, convenient manufacture, installation and maintenance, low cost, good stability, no noise and small volume, saves space, and is bound to become the main attack direction of wind power generation in the future. The blades of the existing vertical axis wind driven generator are divided into a resistance type and a lift type, and the two types have a common problem that wind power for offsetting useful work exists on the side where work does not need to be done. This is therefore also a direct reason for the lower efficiency and slower development of vertical axis wind turbines compared to horizontal axis wind turbines.
