wind turbine device

Abstract

The invention relates to the field of new energy, in particular to the field of wind power generation. A wind turbine device for wind power generation, the blade device includes a mounting base, a rotating blade assembly, and a centripetal driving device, the rotating blade assembly and the centripetal driving device are installed on the mounting base, and the rotating blade There are three groups of components, which are evenly arranged on the installation base at an angle of 60° to each other; the installation base includes a mounting plate and a flange center pivot; the rotating blade assembly includes blades, blade fixing shafts , a vertical bearing and a swing rod; the centripetal drive device includes a centripetal slider, a connecting rod, a pin shaft, a shaft frame and a pressure block, and the blade device also includes a spring device, which resets the blade. The device can adaptively adjust the angle of the blades, thereby improving the efficiency of wind power generation and avoiding accidents due to different wind fields.

Description

technical field [0001] The invention relates to the field of new energy, in particular to the field of wind power generation. Background technique [0002] With the massive consumption of fossil energy and the accelerated deterioration of the human living environment, wind energy, as a relatively clean, stable and reliable renewable energy, has received more and more attention. Keep deepening. However, in low-speed wind fields, high-speed wind fields and variable wind fields, the wind rotor not only cannot operate in the best CP state; at the same time, the fatigue degree of the blades is increased, and the service life of the wind turbine is shortened. This makes the problem of easy start-up and rapid braking of wind turbines always a difficult point. In order to overcome the above-mentioned technical problems, although additional power start-up and braking are feasible, other energy sources are consumed, thereby reducing the utilization rate of wind energy.

Problems solved by technology

However, in low-speed wind fields, high-speed wind fields and variable wind fields, the wind rotor not only cannot operate in the best CP state; at the same time, the fatigue degree of the blades is increased, and the service life of the wind turbine is shortened.

This makes the problem of easy start-up and rapid braking of wind turbines always a difficult point. In order to overcome the above-mentioned technical problems, although additional power start-up and braking are feasible, they consume other energy sources and reduce the utilization rate of wind energy.
