Abstract

The invention belongs to the technical field of wind power generation and relates to a vertical shaft power generator blade set capable of changing a wind facing angle. The blade set comprises a mainsupporting shaft, a wind direction instrument, a speed reducing motor, a servo system, a main intermittent gear, auxiliary intermittent gears, a first bevel gear set, a second bevel gear set, a bladetransmission shaft, a blade main shaft and blades; the number of the auxiliary intermittent gears is 4-10, and the auxiliary intermittent gears are uniformly distributed in the circumferential direction of the main intermittent gear; a gear disk of the main intermittent gear is equally divided into four sector-shaped regions of the same area; gear teeth are not arranged on the outer edges of two sector-shaped regions opposite in vertex angle; and gear teeth are arranged on the outer edges of the other two sector-shaped regions opposite in vertex angle. By utilizing the vertical shaft power generator blade set capable of changing the wind facing angle, under the wind power effects, each blade can change the wind facing angle, and then the blade set generates the maximum rotating torque in the positive direction and the minimum rotating torque in the reverse direction, the vertical shaft power generator blade set capable of changing the wind facing angle is effectively applied to a vertical shaft wind power generator, and the power generating efficiency of the vertical shaft wind power generator is improved.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and relates to a vertical-axis generator blade set with a variable windward angle. Background technique [0002] Wind power is a clean, renewable energy source that is abundant and infinitely usable. Most of the traditional wind turbines are horizontal axis, but the disadvantages of horizontal axis wind turbines are: wind-facing devices are required, the efficiency of wind energy utilization is unstable, the operation noise is large, and installation and maintenance are difficult. Compared with horizontal-axis wind turbines, vertical-axis wind turbines have the advantages of no wind direction, low operating noise, and convenient installation and maintenance, and have been sought after by industry insiders. However, during the use of vertical axis wind turbines, there are both positive and reverse rotational moments, which makes the utilization efficiency of wind energy low and affe...
