Description

Vertical shaft ring blade wind turbine

technical field

The utility model relates to a vertical shaft ring blade wind power generator, in particular to a power generation device using wind power as power.

Background technique

Wind energy is an inexhaustible source of energy on the earth, especially in China, which has a vast land and abundant resources, and some areas in the northwest are world-famous "wind outlets". The wind energy resources are very rich. Making full use of these wind energy is very suitable for China's national conditions and In line with the international slogan of environmental protection and full use of renewable resources. However, in the area where the wind direction changes frequently in the existing horizontal-axis propeller wind generators, the blades of this horizontal-axis generator cannot face the wind direction, which will greatly reduce the overall efficiency, and the large-scale will increase the manufacturing cost and inconvenient installation. , in order to make full use of wind energy, improve the efficiency of wind energy use, make wind power generation more popular, and reduce manufacturing and installation costs, the inventor invented the vertical shaft ring blade wind generator to make up for the deficiencies in the prior art.
