A horizontally rotatable wind guiding device and a vertical axis wind generator

Abstract

The invention relates to a horizontally rotatable wind guiding device and a vertical axis wind power generator. The horizontally rotatable wind-guiding vertical-axis wind turbine includes a nacelle, a horizontally rotatable wind-guiding device, a wind wheel, a support device, a base, and a top cover; the second cylindrical structure is located on the first cylindrical structure of the horizontally rotatable wind-guiding device inside and have the same axis with the first cylindrical structure, a transmission shaft is provided at the axis, and the diameter of the second cylindrical structure is smaller than the diameter of the first cylindrical structure; the first cylindrical structure, the second cylindrical structure The support device, the nacelle, the base, and the bottom end of the nacelle are arranged in sequence below; the top cover is located above the first cylindrical structure and the second cylindrical structure, and the top cover is sleeved outside the drive shaft; the bottom end of the drive shaft passes through the coupling connected to the generator set. The invention can significantly improve the utilization rate of wind energy.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a horizontally rotatable wind guiding device and a vertical axis wind power generator. Background technique [0002] With the continuous increase of people's demand for energy, especially the increasing demand for electricity, power generation in my country and many countries mainly depends on coal, oil, natural gas, commonly known as "thermal power", and minerals (nuclear power). It belongs to non-renewable energy, and the excessive mining of these non-renewable energies will always be exhausted, and in the process of burning these non-renewable energies, a large amount of carbon dioxide, dust and pollutants will inevitably be released into the atmosphere. The air we live in is seriously polluted. As far as China is concerned, there are more and more days of PM2.5 exceeding the standard in many provinces every year, so it is urgent to control the environm...

AI Technical Summary

Problems solved by technology

In summary, these problems make the wind energy obtained by the generator exponentially decrease

[0006] 3. Since the chassis and impeller blades of the three-bladed paddle wind turbine are all installed on the top of the iron tower with a height of tens of meters or nearly a hundred meters, it is difficult to install; Generators and all the internal components of the engine room are required to achieve high reliability and precision in the process of manufacturing, which greatly increases its manufacturing cost

[0007] Due to the large investment and low yield of the three-bladed paddle wind turbine, for now, the three-bladed paddle wind turbine can only be used as a supplement to power generation equipment
