Abstract

The invention relates to an adjustable wind power generation device, namely a vertical axis wind wheel connecting rod combination variable pitch wind power generation device. The vertical axis wind wheel connecting rod combination variable pitch wind power generation device includes a lower support plate, an upper support plate which are sleeved on the central shaft of the wind wheel, and a wind wheel blade plate which arranged between the upper support plate and the lower support plate. A power generation rotor is fixedly connected with the lower supporting plate, and the stator is fixed on the central shaft of the wind wheel. A blade plate support shaft is arranged between the upper support plate and the lower support plate, and the wind wheel blade plate is arranged on the blade plate support shaft and rotates around the blade plate support shaft. A variable pitch system capable of adjusting the working position of the wind wheel blade plate is arranged on the central shaft of the wind wheel. The vertical axis wind wheel connecting rod combination variable pitch wind power generation device can effectively lower the rotating speed of the wind wheel, reduced the wind energy conversion rate of the vertical axis wind wheel, and achieves the overload protection for a permanent magnet generator.

Description

technical field [0001] The invention relates to an adjustable wind power generation device, in particular to a wind power generation device with a combination of vertical axis wind wheel connecting rod and variable pitch. Background technique [0002] Wind energy is inexhaustible, inexhaustible, does not consume resources, clean and hygienic, and has a wide range of distribution. Wind power generation has become an important part of the sustainable development strategy of many countries in the world. Compared with horizontal axis wind turbines, vertical axis wind turbines have the advantages of simple structure, low cost of construction and maintenance, and no need for windward adjustment systems. The vertical axis wind turbine mainly includes a vertical axis wind rotor, a wind turbine, a power storage and output control unit, and the like. The vertical axis wind wheel directly drives the permanent magnet generator, which is one of the development trends in the field of win...
