Abstract

A device (10) for wind power generation, comprising: a blade assembly (20) having a plurality of radially extending blades (22) surrounding a hollow space (24); a frame structure (30) inside which the blade assembly (20) is rotatably mounted; and a power generating unit (40) connected with the blade assembly (20); wherein the blade assembly (20) is rotatable by at least one air flow directed into the blade assembly (20), so that rotation of the blade assembly (20) is adapted to drive the power generating unit (40) to thereby generate electrical energy. And a system (100) comprises a plurality of the devices (10) arranged in at least one of a horizontal and a vertical arrangement relative to one another.

Description

technical field [0001] The invention relates to the field of wind power generation. Background technique [0002] Wind power has become an increasingly important renewable energy source as an alternative to fossil fuel power generation. Different types of wind generators or so-called "wind turbines" are used in areas with open land spaces and high wind resources. Conventional wind turbine designs include horizontal axis wind turbines (HAWT) and vertical axis wind turbines (VAWT), which differ from each other in that they have different orientations of the axis of rotation, ie, horizontal rotation or vertical rotation, respectively. The most common type of horizontal axis wind turbine usually includes two or three wind blades arranged towards the wind direction. These blades are connected to the wind rotor shaft and the generator, and they are located on top of the tower, which is usually about tens of meters high. Examples of vertical axis wind turbines include H-type Gir...
