Embodiment 1

[0048] Such as figure 1 As shown, a kind of double-bladed wind power generation method of this embodiment utilizes a special wind power generation system to generate power according to the following steps:

[0049] Step 1. The crosspiece of the blade of the wind turbine is placed on the air flow path, and the pressure difference of the air flow before and after the blade forms resistance to push the blade to rotate;

[0050] Step 2, the rotation of the blade is transmitted to the transmission box 200 through the gear, and the transmission box 200 is transmitted to the frame 100 through the gear;

[0051] Step 3: The rack 100 is driven to the generator unit through gears, and the generator unit generates electricity and converts wind energy into electrical energy.

[0052] The wind power generation system adopted in this embodiment is as Figure 2-Figure 11 As shown, the wind power generation system includes a frame 100, a generator unit and blades, a generator unit is arrang...

Embodiment 2

[0067] A wind power generation system in this embodiment has the same basic structure as in Embodiment 1. Furthermore, the blades in this embodiment also include auxiliary blades. Specifically, first auxiliary blades 340 and second auxiliary blades are arranged on both sides of the first vertical shaft 310. The second sub-blade 350, the first sub-blade 340 and the second sub-blade 350 are all arc-shaped blades and both form a centrally symmetrical S-shaped structure on both sides of the first vertical shaft 310, and the arc-shaped concave direction of the first sub-blade 340 is in line with the The arc-shaped concave section of the first blade 320 close to the first vertical shaft 310 is oppositely arranged, and the arc-shaped concave section of the second auxiliary vane 350 is arranged opposite to the arc-shaped concave section of the second blade 330 close to the first vertical shaft 310, that is, as figure 2 As shown in the middle position, the arc section of the S-shaped b...

Embodiment 3

[0071] A wind power generation system in this embodiment has the same basic structure as that in Embodiment 2. Furthermore, the blades in this embodiment also include cutting blades. Specifically, the side of the first blade 320 away from the first vertical shaft 310 is arranged along the height direction. There is a first cutting blade 360, and the side of the second blade 330 away from the first vertical shaft 310 is provided with a second cutting blade 370 along the height direction. A secondary blade 340 shrinks relatively inwardly, and the thickness of the first cutting blade 360 ​​gradually decreases along the direction away from the first blade 320, and the top end of the first cutting blade 360 ​​extends obliquely downward along the direction away from the first blade 320, the first The bottom end of the cutting blade 360 ​​extends upwardly in a direction away from the first blade 320; similarly, the second cutting blade 370 extends obliquely in a direction close to the...

Abstract

The invention discloses a double-blade wind power generation method, which belongs to the field of wind power generation. The present invention adopts a wind power generation system, and proceeds according to the following steps: step 1, the crosspiece of the wind turbine blade in the wind power generation system is on the air flow path, and the pressure difference between the front and rear of the air flow forms resistance to push the blade to rotate; step 2, the blade rotates through The gears are transmitted to the transmission box, and the transmission box is transmitted to the frame through the gears; step 3, the frame is transmitted to the generator unit through the gears, and the generator unit generates electricity and converts wind energy into electrical energy. The invention overcomes the disadvantages of low utilization rate of wind energy and high production cost of wind power generation in the prior art, and provides a double-blade wind power generation method with low cost, strong applicability and wide application range.

Description

technical field [0001] The invention relates to the technical field of wind power generation, and more specifically, relates to a double-blade wind power generation method. Background technique [0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean and pollution-free renewable energy source. It has been used by people for a long time, mainly through windmills to pump water and grind flour. Now, people are interested in The most important thing is how to use wind to generate electricity. Wind is one of the energy sources without pollution, and it is inexhaustible. It is very suitable for coastal islands, grassland pastoral areas, mountainous areas and plateau areas that are short of water, fuel and inconvenient transportation. , a lot to do. The use of wind power to generate electricity is very environmentally friendly and has a huge wind energy reserve, so it is increasingly valued by countries all over...
