Abstract

The present invention provides a vertical axis wind power generator in which the angle of the blade is adjusted by a rope loop, which comprises a plurality of blades and a rope loop, and the blade is hinged to a bracket on the motor main shaft; a pulley is provided at a vertical side of the blade, and the The loops are wrapped around pulleys on the plurality of blades. The blade of the present invention is hinged with the support on the motor main shaft; therefore, the blade of the present invention can rotate; the centrifugal force caused by the different positions of the blades is different, which will cause the vibration of the motor main shaft; and a vertical side of the blade of the present invention is provided with a pulley , the pulleys on the plurality of blades are wrapped with upper rope rings; the rope rings can limit the rotation angle of the blades, reduce the difference in the centrifugal force of each blade, and make the present invention run smoothly; and the blades of the present invention can rotate, and the blades at the return stroke The received wind resistance is small, which greatly improves the utilization efficiency of wind energy of the present invention; the present invention also has the advantages of simple structure, convenient maintenance and low cost.

Description

technical field [0001] The invention relates to a wind power generator, in particular to a vertical axis wind power generator in which the blade angle is adjusted by rope loops. Background technique [0002] Most of the blades of existing vertical axis wind generators are fixedly installed, so that when generating electricity, some blades do positive work under the action of wind force, and some blades do negative work under the action of wind force, so that the wind power can be utilized The efficiency is low, and the wind power cannot be fully utilized. [0003] In order to improve the utilization rate of wind energy, the blade rotor technology is mostly adopted, and the commonly used blade rotor technology includes the planetary gear blade rotor technology and the blade off-axis self-rotating rotor technology. Planetary gear blade rotor technology, the blade shaft is connected to the planetary gear, the fan shaft is connected to the sun gear, and the planetary gear and t...
