Intelligent wind wheel used for vertical axis wind generating device

Abstract

The invention relates to an intelligent wind wheel, in particular to an intelligent wind wheel used for a vertical axis wind generating device. The intelligent wind wheel used for the vertical axis wind generating device comprises an upper wheel rim and a lower wheel rim; a support bar and a vane shaft are arranged between the wheel rims; the vane shaft is provided with a wind sail; the wheel rims, the support bar and the vane shaft form a regular prism; the middle part of the regular prism is provided with a wheel shaft; and a wheel hub is arranged between the wheel shaft and the wheel rim. The intelligent wind wheel used for the vertical axis wind generating device has the advantages and effects that the wind wheel does not need a windward adjusting system and can receive wind from any direction in an orientation of 360 degrees, and a main shaft permanently rotates towards the design direction. The wind sail rotates along a self shaft, and continually changes direction so that the tangential stress of the wind sail is maximized down the wind and the wind sail against the wind is parallel to the wind direction. The rotating angle of the wind sail is judged by a main controller according to the indication of a wind indicator and the current rotating relative position of the wind sail, and information is transmitted to a wind sail controller. The intelligent wind wheel used for the vertical axis wind generating device can reduce the cost, is convenient to maintain, and has low pneumatic noise.

Description

technical field [0001] The invention relates to an intelligent wind wheel, in particular to an intelligent wind wheel used for a vertical axis wind power generation device. Background technique [0002] Stable, reliable and clean energy supply is the guarantee of human civilization, economic development and social progress. Fossil energy such as coal, oil, and natural gas supported the progress and development of human civilization for nearly 200 years in the 19th and 20th centuries. However, the massive consumption of fossil fuels not only makes human beings face the pressure of resource depletion, but also feels the threat of environmental degradation. The 21st century is a century of rapid development of science and technology, economy and society. It will also be a century of transition from the era of fossil fuels to the era of renewable energy with sustainable utilization capabilities, and gradually create a new era of energy for human beings to get rid of the shackle...

Problems solved by technology

The system is expensive and difficult to maintain

[0007] 3. The tip speed ratio of the horizontal axis wind rotor is generally around 5~7. At such a high speed, the cutting airflow of the blade will produce a lot of aerodynamic noise. At the same time, many birds are hard to escape under such a high speed blade.

[0008] However, the main problems of the existing vertical axis wind rotors are: the blades are fixed, and the efficiency is low; each blade is supported by two hubs, and the strength is not large enough to achieve high power
