Single blade wind generator

Abstract

The invention provides a single-fan blade wind generator which is simple in structure, adopts a single fan blade for wind collection, enables power output to be realized under blowing of breeze, does not need a fan blade stall control system and a fan blade transformation attack angle control device, and enables wind generator equipment to be convenient to mount and simple to manufacture. The single-fan blade wind generator comprises a fan blade, a power generator, a main shaft, a hollow transmission shaft, a left upright post, a right upright post, a first one-way driver, a second one-way driver and a reversing gear, and is characterized in that the main shaft is in consubstantial connection with the shaft of the power generator; bearings are mounted at two ends of the main shaft, and outer rings of the bearings at the two ends are respectively connected with upper ends of the right upright post and the left upright post; the power generator is mounted on the right upright post; the inner ring of the first one-way driver is mounted on the main shaft through a shaft pin, and the outer ring of the first one-way driver is fixedly connected with the inner ring at one end of the hollow transmission shaft, the hollow transmission shaft is mounted outside the main shaft, and a bearing is mounted at the other end of the hollow transmission shaft; the inner ring of the bearing is connected with the main shaft; the fan blade is mounted on the outer ring of the hollow transmission shaft.

[0002] Wind energy, as a natural green renewable power source, has been paid more and more attention by countries all over the world. Countries in the world have made great achievements in using wind power to generate electricity. More than m / s, and the wind blades of current wind energy generators are multi-piece wind collecting and rotating, the bulky equipment, high manufacturing cost and installation requirements have restricted the full utilization and popularization of wind energy, especially when there is light wind Wind energy generators have technical problems such as difficulty in starting or insufficient output power. The huge manufacturing cost of the fan blade stall control system at high wind speeds is also the bottleneck of current wind energy generation technology, so wind energy generation cannot be well applied and promoted.

The patent application number is 200510003199.4 discloses a swing type wind power device. Although a single fan blade is used, the mechanical structure of the blade reversing angle of attack control principle is relatively complicated.
