The single-axis two-group blade wind turbine according to the above, wherein the rotating bracket is provided with a rotating portion and a base, the rotating portion is connected to the power output unit at one end, and the base is connected to the base at the other end, so that the rotating portion is at the base The seat rotates horizontally.

The single-axis two-group blade wind turbine is characterized in that the materials of the first windward blades and the second windward blades are selected from the group consisting of canvas, plastic and metal materials.

The single-axis two-blade wind turbine according to the above, wherein the materials of the first small blades and the second small blades are selected from any one of canvas, plastic and metal materials.

In order to further understand the features, features and technical contents of the present invention, please refer to the following detailed description of the present invention and the accompanying drawings, which are only for reference and description, and are not intended to limit the present invention.

Please also refer to the first figure and the second figure. The single-axis two-group blade wind turbine includes: a first shaft 1 with a plurality of first windward blades 11 at the outer end, the first winds The sheet 11 is evenly arranged in a radial shape; a second shaft 2 is provided with a plurality of second windward sheets 21 at the outer end, the second windward sheets 21 are arranged in a radial average; and a rotating bracket 3 is provided at the top end a power output unit 31, the power output unit 31 is symmetrically coupled to the first shaft 1 and the second shaft 2, and the first windward blades 11, the first small blades 12, and the second windward blades 21 are driven by the wind. Inverting with the second small blade 22 to drive the first shaft 1 and the second shaft 2 to rotate vertically in the power output unit 31 to provide power energy, by the first windward blades 11 and the first small blades 12. The second windward sheet 21 and the second small blade 22 increase the wind receiving area of the wind turbine and increase the operating efficiency.

Referring to the third figure, when the wind blows to the original single-axis two-group blade wind turbine, the first windward blades 11 and the second windward blades 21 become the wind receiving surface, and fold the displacement along the airflow traveling direction. The first small blade 12 and the second small blade 22 that are coupled to the shaft also rotate synchronously, and are automatically opened by the wind to extract the wind; when the first windward blade 11 and the second windward blade 21 are pushed by the wind upward When turning, the angle of folding of the first small blade 12 and the second small blade 22 is also larger. When the first windward blade 11 and the second windward blade 21 are turned downward, the first small blade 12 and the second small blade 22 are Will open, which will increase the overall speed and improve power generation efficiency.

Please refer to the fourth figure, wherein the rotating bracket 3 is provided with a rotating portion 32 and a base 33. One end of the rotating portion 32 is connected to the power output unit 31, and the other end is connected to the base 33, so that the rotating portion 32 is The base 33 is horizontally rotated, and by the rotatable characteristic of the rotating portion 32, regardless of which wind direction the wind is blown, the rotating portion can be horizontally rotated by the wind pushing the first windward sheet 11 or the second windward sheet 21 to The wind turbine has the largest wind receiving area and improves the operating efficiency.

According to the above description, the materials of the first windward sheet 11 and the second windward sheets 21 are selected from the group consisting of canvas, plastic and metal materials.

According to the above description, the materials of the first small blades 12 and the second small blades 22 are selected from any one of canvas, plastic and metal materials, and the first small blades 12 and the The second small blades 22 can be easily disassembled, so that the single-shaft two-group blade wind turbine can be conveniently transported and assembled by the user.

However, the above descriptions are only preferred embodiments of the present invention. When it is not possible to limit the scope of the creation of the creation, the changes and modifications that can be made by those who are familiar with the industry should be regarded as not deviating.
