Problems solved by technology

The horizontal axis fan has a fast speed, but the starting wind speed is relatively high, and the utilization rate of the breeze is low; the vertical axis fan has a large starting torque, due to the resistance generated during rotation, the tip speed ratio is low, and the size, weight and cost are certain. conditions, the output power provided by the low
Although the Darrieux lift type vertical axis fan has relatively high efficiency, it has the disadvantage of not being able to self-start
In addition, the existing fan still has the problem of difficult maintenance at high altitudes

Abstract

The invention relates to an angle-type wind-force generator, comprising vanes, generator, gear box, arrester, arrester link rod, inclined column bearing, cable, windward motor, windward gear, tail helm, gear box, machine seat and tower frame, where each vane is a petal-like, bucket ram-type vane whose section is wing-shaped, and plural vanes are integrally designed into a flower shape, and the machine set comprises a vane structure, inversely hanging on a windward frame on the front side of a transverse support rod tower and having a barycenter deviating from the hanging point and having a rotating shaft with a windward elevation angle of 10-89 deg.C, and the windward frame is provided with a pair of limit blocks. And the invention is also provided with a machine set lifting mechanism comprising two pulleys and steel wire rope. And it is convenient to electricity generation with breeze and able to make the vanes fast rotate to output higher power and carry out brake speed regulation and protection by the integral elevation of the machine set and vane structure, and the whole machine set is completely convenient to fall to the ground for maintaining. And it is a novel wind-force generator with certain ornamentality.

Description

technical field [0001] The invention relates to an oblique axis wind power generating device. Background technique [0002] As the environmental problems caused by conventional energy sources become increasingly prominent, wind power, as a clean energy source, has attracted more and more people's attention. After experiencing the test of long-term operation, it has gradually developed into a market structure dominated by horizontal and vertical axis wind turbines. The horizontal axis fan has a fast speed, but the starting wind speed is relatively high, and the utilization rate of the breeze is low; the vertical axis fan has a large starting torque, due to the resistance generated during rotation, the tip speed ratio is low, and the size, weight and cost are certain. conditions, the output power provided is low. Although the Darrieux lift type vertical axis fan has relatively high efficiency, it has the disadvantage of not being able to self-start. In addition, the existing...
