Abstract

The invention relates to a paddle for a vertical-axis wind power generator, in particular to a spiral combined paddle for the vertical-axis wind power generator, belongs to the field of power generation equipment, and aims at solving the problems that an existing vertical-axis wind power generation wind power paddle is large in wind resistance, the wind power starting torque is large, power generation continuity of a power generator cannot be kept, and a large-power vertical-axis wind power generation paddle is large in size and not convenient to transport or assemble. The spiral combined paddle comprises at least one paddle body, an upper cover and a lower cover, and the upper end and the lower end of the paddle body are connected with the upper cover and the lower cover correspondingly.

Description

technical field [0001] The invention relates to a blade for a vertical axis wind power generator, in particular to a helical combined blade for a vertical axis wind power generator, which belongs to the field of power generation equipment. Background technique [0002] At present, the global energy crisis is gradually intensifying, and the utilization of renewable energy has received extensive attention. For example, solar energy, wind energy, and tidal energy have developed rapidly, and many wind power stations have been established one after another. In the field of wind power generation, due to the advantages of low cost and convenient maintenance of vertical axis wind turbines, vertical axis wind turbines are gradually developing towards large-scale and rapid development. In the field of vertical axis wind power generation, reducing the starting torque of the blades and facilitating the assembly of blades for power generation equipment are key issues for high-power axial...
