Abstract

The invention discloses a small horizontal axis wind turbine for driving blades and a power generation method thereof. The resistance of the blades largely reduces the efficiency of a wind driven generator. Two spokes on the same one side are respectively fixed with two ends of one blade mounting shaft; the blade mounting shafts and the blades form rotating pairs; the blades are divided into two parts with different chord lengths by the axes of the blade mounting shafts; stop rods are respectively fixed on the inner sides of two blade mounting shafts; the stop rods include first cross bars, vertical rods, second cross bars and stop rings; the stop rings are fixed at the bottom ends of the second cross bars; included angles between the second cross bars and the spokes are 5-10 degrees; the directions of the stop rings of the two stop rods are opposite; and an upper hub is supported on a rotor of the generator, and is connected with the rotor of the generator through a clutch. The blade mounting shafts divide the blades into unequal parts to force the blades to deflect; and the stop rods control the deflecting angles of the blades to reach the optimal windward area, so that the efficiency of the generator is improved.

Description

technical field [0001] The invention relates to a wind power generator, in particular to a small vertical axis wind power generator driving blades and a power generation method thereof. Background technique [0002] There are two main types of wind turbines, horizontal axis and vertical axis. Horizontal axis wind turbines are suitable for outdoor wind farms where the wind direction and speed are relatively stable, and are not suitable for installation in cities where the wind speed and direction change relatively frequently, while vertical axis wind turbines, especially H-type vertical axis wind turbines, can work very well. Adapt to the characteristics of urban wind conditions. Vertical axis wind turbines are off-grid wind power generation equipment, which are mainly used in small-scale power consumption places such as urban street lights, LED display boards, and remote mountainous users without electricity. Traditional H-type generators mainly improve power generation ef...
