Wind driven generator with self-driven frame

Abstract

The invention discloses a wind driven generator with a self-driven frame. The self-driven frame comprises a plurality of blade frames, a plurality of blades arranged in the blade frames, and a driving control device used for controlling the windward angles of the blade frames and the blades. The driving control device adjusts the windward angles of the blade frames and the blades in the blade frames according to the wind direction, the blades in all the blade frames generate torsion with the same rotating direction, and all the torsion generates moment on a driving shaft to push the driving shaft to rotate and drive the generator to generate electricity. When the wind direction mode is changed, the relative positions of the blades, the wind direction and the driving shaft are changed, the windward angle of each blade is changed along with the change and is a fixed value, and the blades are the same, so that a torsional moment in the same rotating direction is obtained, and the overall stable operation is realized. The wind driven generator is flexible in structure, adjustable in size and wide in application range. The self-spinning force of the blades and the self-spinning force generated when the eccentrically-designed blade frames transmit power are superposed, rotation is light and external power is not needed, and the conversion efficiency is improved.

Description

technical field [0001] The invention relates to a self-driving frame wind power generator, belonging to the technical field of wind power generation equipment. Background technique [0002] Due to the energy crisis, researchers are always looking for better ways to use natural energy, such as solar, wind, hydro, etc. In terms of wind power generation, the existing technology provides many technical solutions, but there is always a problem of low wind energy conversion rate. Moreover, the existing wind power generation, the practical application of three-blade wind turbines, has a structure composed of a wind wheel, a speed increase It is composed of a generator and a generator, wherein the control system is connected to the wind direction and anemometer, and according to the measurement results, the pitch mechanism is driven to rotate the blades. This kind of wind turbine has requirements for different levels of wind power, and the installation structure of the three-blade ...

Problems solved by technology

In terms of wind power generation, the prior art has provided many technical solutions, but there is always the problem of low wind energy conversion rate. Moreover, the existing wind power generation, the three-bladed wind power generator in practical application, has a structure consisting of a wind wheel, a speed-increasing The control system is connected to the wind direction and speed measuring instrument, and according to the measurement results, the pitch change mechanism is driven to rotate the blades.

Due to the requirements for different levels of wind power, and the installation structure of the vertical wind direction of the three blades, the conversion efficiency of this kind of wind generator is not high. Generally, a large amount of installation is required, and the investment is large and the cost is high.
