Example Embodiment

[0029] 1; First of all, I hope that this patented technology will establish a consensus with the booming wind power industry in my country, and turn the patent into reality.

[0030] 2. As mentioned in "11." of the technical description of the variable-blade vertical axis wind turbine; the patented variable-blade vertical axis wind turbine is divided into three series. The power generation of small series is 100WD to 1000W, 10KW. For home use. The power generation of medium-sized series is 10KWD to 100KW, which is used by institutions, enterprises and institutions, and can be installed on the top of high-rise buildings. The large-scale series power generation is 100KW to 10MW, which is suitable for the construction of wind power plants.

[0031] 3; The most important thing is to build a 100W small variable-blade vertical axis wind turbine during the patent application and patent approval period to verify and demonstrate the advanced nature, feasibility and practicability of ...

Abstract

The invention relates to a vertical axis wind turbine. Wind paddles in vertical N layers are arranged on a hub of a vertical shaft, wherein the N is an integer from 1 to 6; N1 paddle groups are arranged on the wind paddles in each layer, wherein the N1 is an integer from 1 to 6; N2 paddle blades are arranged on each paddle group, wherein the N2 is an integer from 1 to 6; and each paddle blade is a rectangular revolving door type flat blade, and the direction of each blade is changed by means of automatic pushing of the wind direction and the wind force. The paddle groups in a first phase area and a fourth phase area are positioned at the operating phase positions and are identical to supporting frame rods of the paddle groups in direction, the paddle groups rotating into a second phase area are positioned at the half-operating area and are perpendicular to the supporting frame rods of the paddle groups, and the blades are automatically parallel to and kept consistent with the wind direction when the paddle groups rotate into a third phase area. The rotating diameter of an impeller of the wind turbine is adjusted mechanically to enable the rotating speed of the wind turbine to be basically stable. The variable-paddle type vertical axis wind turbine has a safe, reliable and automatically-adjusted control device, so that the windward areas of the wind blades are automatically adjusted along with increase of the wind speed, and further the rotating speed of the wind turbine is kept constant and unchanged.

Description

Technical field: [0001] This patent relates to the technology of vertical axis wind turbines, especially the field of vertical axis wind turbines with variable blades. technical background: [0002] Wind energy is an inexhaustible renewable emerging green energy. Energy has become increasingly tense since the beginning of this century. Countries and governments around the world have raised the wind power industry to an important position and vigorously promoted and supported it. However, the current domestic wind power generation is dominated by horizontal-axis spiral wind turbines. Although the oldest wind turbine from Europe has been improved by the most advanced modern technology, it is still quite expensive, difficult to manufacture and install. To this end, countries are developing new wind turbine technology. The direction is the vertical axis wind turbine. Japan has the largest investment. Currently, there are small vertical-axis wind turbines of vertical ribbon ...
