Embodiment 1

[0023] Taking the standard blade airfoil GOE573, GOE630, GOE364, GOE436, GOE118, GOE147 as an example, the supporting wing is connected to the vertical axis, the blade is installed on the supporting wing, and the convex surface of the blade is installed facing the vertical axis. Set the blade rotation angle to 12 degrees.

[0024] Airfoil / azimuth angle

[0025] When the concave surface is installed facing the vertical axis, the other conditions of the test remain unchanged, the wind wheel cannot rotate, and the magnitude of its driving torque cannot be measured.

Embodiment 2

[0027] Choose the Goe 364 type blade in Example 1, the diameter of the wind wheel is 1.36 meters, the length of the blade is 1 meter, and the following fixed blade rotation angles (unit: degree) are set respectively, corresponding to different wind speeds (unit: m / s), and the generator is measured The output power (unit: watts), as shown in the following table.

[0028]

[0029] From the above table and Figure 4 It can be seen that when the blade rotation angle is in the range of 2 to 12 degrees, the wind speed is in the range of 6 to 13 m / s, and the output power is 9 to 360 watts, which has an ideal output power.

Embodiment 3

[0031] Choose the Goe364 type blade in Example 1, choose the same diameter wind wheel as in Example 2, the same length of the blade and fixed blade corner, under the same wind conditions, only the concave surface 12 facing the vertical axis 2 to install the blade Other experimental conditions are the same as in Example 2. The wind turbine is tested, and the experimental results show that the wind wheel cannot rotate, that is, the generator does not output power at all, which lacks industrial practicability.

[0032] In summary, in a natural environment, a wind speed of 6-13 m / s is an ideal wind speed range for wind energy applications, which shows that the present invention has industrial applicability and creativity.

Abstract

The invention relates to a vertical-shaft wind generating set, especially a method for installing vanes able to effectively raise efficiency of the vertical-shaft wind generating set, connecting a vertical shaft with supporting wings, and installing the vanes on the supporting wings, where the wings of the vanes are nonsymmetrical wings with bending and the salient surfaces of the vanes are arranged opposite to the vertical shaft. And the invention is applied to industrial production.

Description

Technical field [0001] The invention relates to a vertical axis wind power generator, in particular to a blade installation method that can effectively improve the efficiency of the vertical axis wind power generator. technical background [0002] In order to make better use of wind energy, for a long time, people have designed a variety of structural forms of wind power generation devices, according to the different positions of the wind turbine rotation axis in the space direction, divided into the horizontal direction of the horizontal axis wind turbine and the vertical direction of the vertical Axis wind turbine. [0003] Such as figure 1 As shown, generally speaking, the wind wheel of the vertical axis wind turbine is composed of straight blades 1 with a certain wing shape, and the axis of the blades is parallel to the main shaft, that is, the vertical axis 2. The wing shape of the blade can be designed according to existing aerodynamic principles. [0004] Regarding the ex...
