Flexible variable propeller mechanism of aerogenerator

Abstract

The invention relates to an adjustment mechanism of a wind power generator, in particular to a flexible oar variable mechanism of the wind power generator. The adjustment mechanism comprises a wind wheel arranged in the front end of a mainshaft and an oar blade arranged on the wind wheel. A blade shaft fixedly connected with the lower end of the oar blade is inserted into the wind wheel through abearing; a coil spring is sleeved on the blade shaft; the center of the wind wheel is fixedly provided with a synchronizer; the synchronizer comprises a shell and a synchronizing shaft arranged in the shell through the bearing; the synchronizing shaft is coaxial with the mainshaft; a synchronizing conical gear is arranged on the synchronizing shaft; the bottom end of the blade shaft runs through the shell of the synchronizer and is fixedly provided with a conical gear of the blade shaft; and the synchronizing conical gear is engaged with the conical gear of the blade shaft. The mechanism doesnot need extra energy or manual control and has a simple and reliable structure; a plurality of the oar blades are synchronously adjusted and have good consistency; a worm of a worm gear is arranged to have more convenient adjustment and maintenance; and a stepper is arranged to remove the influence of misoperation caused by instantaneous gale.

Description

technical field [0001] The invention relates to an adjusting mechanism of a wind power generator, in particular to a flexible pitch-changing mechanism of a wind power generator. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge, and the global wind energy is about 2.74×10 9 MW, of which the available wind energy is 2×10 7 MW is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. China's wind energy reserves are large and widely distributed, and the wind energy reserves on land alone are about 253 million kilowatts. With the development of the global economy, the wind energy market has also developed rapidly. Wind generators use wind energy to drive the blades to drive the main shaft, and when the relative displacement of the stator and rotor occurs, the magnetic field lines are cut and current is generate...
