Novel vertical shaft wind power generator

Abstract

The invention discloses a novel vertical shaft wind power generator which comprises a left starting auxiliary wing cup (1), a right starting auxiliary wing cup (2), a blade rotating support (4), a power generator (5), a vertical shaft flange (6), a tower rod (7) and two symmetrically-mounted lift blades (9). The power generator (5) comprises a clamping ring (51), an upper end cap (52), a lower end cap (53), a power generator lead (54), an upper bearing (55) and a lower bearing (56), the lift blades (9) are connected with the blade rotating support (4) through hinges (3), a maintenance platform (8) and a climbing ladder (10) are arranged on the tower rod (7), and the left starting auxiliary wing cup (1) and the right starting auxiliary wing cup (2) are hemispherical cups identical in size. Starting performance can be improved remarkably, and the novel vertical shaft wind power generator is simple in structure and high in power generation efficiency.

Description

technical field [0001] The invention relates to wind power generation technology, in particular to a novel vertical axis wind power generator. Background technique [0002] The vertical axis wind turbine was born in the 1930s (1931) and was invented by Dalieu. Its wind energy utilization coefficient and practicability have reached a high level, but due to the poor self-starting performance of the vertical axis wind turbine , and there are safety problems at high wind speeds, so it has not been widely promoted until now, although more start-up assistance has been done on the Dalieu (lift) model, such as: in the H-type lift vertical A set of S-shaped resistance blades is added inside the axial wind turbine to increase the starting performance, but due to its complex structure, it not only increases the cost, but also causes wind resistance and affects the power generation efficiency. Contents of the invention [0003] The object of the present invention is to provide a nove...
