Abstract

The present invention provides a vertical axis wind turbine which adjusts the angles of blades through a loop. The vertical axis wind turbine comprises multiple blades and the loop. The blades are hinged to supports on a motor spindle; pulleys are arranged on one vertical side of each blade, and the loop is wound on the pulleys on the multiple blades. The blades are hinged to the supports on the motor spindle, so that the blades can rotate, the centrifugal force generated by different positions of the blades is different, and thus the motor spindle is made to vibrate; the pulleys are arranged on one vertical side of each blade, and the loop is wound on the pulleys on the multiple blades; the rotation angles of the blades can be limited by the loop, and the difference between the centrifugal force of the blades is reduced, so that the vertical axis wind turbine can work stably; the blades can rotate, the blades on the return stroke is subjected by small wind resistance, and thus the utilization efficiency of the wind energy is greatly improved. The vertical axis wind turbine has the advantages of being simple in structure, convenient to maintain and low in 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...
