Problems solved by technology

However, the performance of the current wind turbines has been greatly improved compared to a few years ago. They were only used in a few remote areas before. The wind turbines are connected to a 15W light bulb to directly use electricity. When it is bright and dark, it will often damage the light bulb.

Embodiment 3

[0034] Based on the intelligent control system of a kind of combined wind energy generator of embodiment 2, its power generation method is:

[0035] Step 1: When the blade on one side of the support rod covers the gap between the two cross bars, the blade on the opposite side rotates around the cross bar under the action of wind to open the gap between the cross bars, and the wind receiving area on both sides of the support rod unbalanced so that the blade 2 rotates;

[0036] Step 2: The controller controls the distance between the two horizontal bars according to the wind speed measured by the wind speed sensor, so as to control the ratio of the wind receiving area of ​​the blades 2 on both sides of the support rod, and then control the speed of the blades 2 and protect the blades 2;

[0037] Step 3: When the wind speed is lower than 20m / s, control the wind receiving area ratio of the blades 2 on both sides of the support rod to 15-20; The wind area ratio is 10-12; when the ...

Abstract

The invention relates to a wind-driven generator with variable windward area, and belongs to the field of wind-driven generators. The wind-driven generator comprises a first electric generator, fan blades and a tail vane. A rotating shaft of the first electric generator is transversely arranged at the top of a supporting rod. The fan blades are connected with a rotor of the first electric generator through a speed increaser. The tail vane is connected to the tail part of a stator of the first electric generator. The middle of the stator of the first electric generator is rotationally connectedwith the supporting rod. Each fan blade comprises a connecting seat, a blade body, a connecting rod, a sliding sleeve and an elastic element, the connecting seat comprises a connecting part, a shaft-shaped part and a cover part which are connected in sequence, the connecting part is used for being connected with the rotating shaft of the wind-driven generator, the shaft-shaped part is sleeved with the sliding sleeve, the sliding sleeve slides along the shaft-shaped part, the elastic element is arranged between a sliding ring and the cover part in a propping mode, the two ends of the connecting rod are hinged to the connecting seat and the middle of the blade body correspondingly, the end of the blade body is hinged to the sliding sleeve, and the fan blades are used for automatically adjusting the windward area of the fan blades according to the wind speed. By means of a second power generation device of the wind-driven generator, the support of existing wind-driven generators can be sufficiently utilized so that wind power can be utilized, airflow in all directions can be utilized to conduct wind power generation, the adaptability is high, the compatibility is good, and the wind-driven generator can be installed vertically and is small in space occupation.

Description

[0001] The present invention is a divisional case of another invention, and its parent application number is: 2016107463037; the application name is: a combined wind energy generator. technical field [0002] The invention relates to a wind power generator capable of changing the wind receiving area, belonging to the field of wind power generators. Background technique [0003] For many centuries, wind turbines, like hydraulic machinery, have been used as power sources to replace manpower and animal power, and have played an important role in the development of productivity. The widespread application of modern electromechanical power and the discovery of oil fields in the Middle East in the 1950s slowed down the development of wind turbines. [0004] In the early 1970s, due to the "oil crisis", there was a problem of energy shortage. People realized the instability and limitation of conventional mineral energy supply, so seeking clean and renewable energy has become an impo...
