Blade angle adjusting device for vertical axis wind turbine

Abstract

The invention discloses a blade angle adjusting device for a vertical axis wind turbine, and relates to the technical field of wind power generation. The blade angle adjusting device comprises a supporting shaft and a blade body; a plurality of supporting disks are arranged on the peripheral side of the supporting shaft in an array manner; supporting plates are distributed along the peripheral sides of the supporting disks; the end part of each supporting plate is movably connected with a mounting plate; the blade body is detachably arranged between the mounting plates in the same vertical direction; the upper surfaces of the supporting disks are matched with mounting disks; locking parts are connected between the mounting disks and the supporting shaft; the circumferences of the upper surfaces of the supporting disks are provided with notch grooves in an array manner; the inner bottom surfaces of the notch grooves are provided with positioning holes; a plurality of assembling holes are formed in one surface of the blade body; and ends of the supporting plates are provided with hinged supports; and the other ends of the supporting plates are provided with through holes. The blade angle adjusting device solves the problem that the blade structure of the existing wind driven generator is fixed and is difficult to adjust under the conditions of different wind directions and wind forces through the actions of the supporting plates, the mounting plates, the blade body, the mounting disks and the locking parts.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a blade angle adjustment device of a vertical axis wind power generator. Background technique [0002] With the rapid development of society and the continuous advancement of science and technology, people's consumption and demand for energy have also increased dramatically. At present, most of the energy widely used by mankind is still the traditional fossil energy represented by coal and oil, but because it is a non-renewable resource, its total storage capacity is decreasing year by year, and the use of fossil energy will generate a lot of pollution. Will cause the greenhouse effect and air pollution, affecting people's health. In recent years, people's demand and development of new energy have been given considerable attention and development. As wind is a new energy source with great potential, wind power generation technology has been deeply rese...
