Embodiment 1

[0044] Such as Figure 1-Figure 11As shown, a power transmission unit for wind power generation in this embodiment includes a transmission box 200 and blades respectively arranged on both sides of the transmission box 200. The blades on each side include a vertical shaft, and the two sides of the vertical shaft are symmetrically distributed There are S-shaped blades in section, and the lower part of the vertical shaft is connected with the transmission box 200 through gear transmission. The power transmission unit in this embodiment is an important power conversion and transmission unit in the wind power generation system, through which power is transmitted to the generator unit, and finally the generator unit is driven to rotate to convert wind energy into electrical energy. The wind power generation system also includes a frame 100 and a generator unit, wherein the transmission box 200 is arranged above the frame 100, and the generator unit is arranged on one side of the fra...

Embodiment 2

[0063]A power transmission unit for wind power generation in this embodiment has the same basic structure as Embodiment 1. Furthermore, the blades in this embodiment also include auxiliary blades. Specifically, first vertical shafts 310 are provided on both sides. The auxiliary blade 340 and the second auxiliary blade 350, the first auxiliary blade 340 and the second auxiliary blade 350 are arc-shaped blades and both form a centrally symmetrical S-shaped structure on both sides of the first vertical axis 310, and the first auxiliary blade 340 The arc-shaped concave direction is set opposite to the arc-shaped concave section of the first blade 320 close to the first vertical shaft 310 , and the arc-shaped concave section of the second auxiliary vane 350 is set opposite to the arc-shaped concave section of the second blade 330 close to the first vertical shaft 310 , that is, figure 2 As shown in the middle position, the arc section of the S-shaped blade of the first blade 320 n...

Embodiment 3

[0067] A power transmission unit for wind power generation in this embodiment has the same basic structure as in Embodiment 2. Furthermore, the blades in this embodiment also include cutting blades. Specifically, the first blade 320 is far away from the first vertical shaft 310. The side is provided with a first cutting blade 360 ​​along the height direction, 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, and the first cutting blade 360 ​​is inclined toward the direction close to the first auxiliary blade 340 Extend, and shrink inward relative to the first auxiliary blade 340, and the thickness of the first cutting blade 360 ​​gradually decreases along the direction away from the first blade 320, and the top of the first cutting blade 360 ​​goes downward along the direction away from the first blade 320 Extending obliquely, the bottom end of the first cutting blade 360 ​​extends...

Abstract

The invention discloses a power transmission unit for wind power generation and belongs to the field of wind power generation. The power transmission unit for wind power generation comprises a transmission box and blades arranged on two sides of the transmission box correspondingly. The blade on each side comprises a vertical shaft, blade bodies with S-shaped sections are distributed on two sidesof each vertical shaft in a central symmetry mode, and the lower portion of each vertical shaft is connected with the transmission box through gear transmission. The blades comprise the first verticalshaft and the second vertical shaft, and the first blade body and the second blade body are arranged on the two sides of the first vertical shaft correspondingly; and the third blade body and the fourth blade body are arranged on the two sides of the second vertical shaft correspondingly, and the section of each of the first blade body, the second blade body, the third blade body and the fourth blade body is in an S shape. The defects that according to wind power generation in the prior art, the wind energy utilization rate is low and production cost is high are overcome, and the power transmission unit for wind power generation is provided, can effectively convert wind energy into electric energy, and is low in cost, high in applicability and broad in application range.

Description

technical field [0001] The present invention relates to the technical field of wind power generation, and more specifically, relates to a power transmission unit for wind power generation. Background technique [0002] As traditional energy resources are facing depletion and environmental pollution, the exploitation of wind resources is becoming more and more important. However, 68% of the wind resource area belongs to the low wind speed area, and the secondary and tertiary wind circles account for 85% of the total wind resources. This part of the resource has always been a difficult problem for wind power exploitation. However, the existing wind power generation technology has the following problems: wind power generators can be roughly divided into two types according to the angle of the rotation axis and the wind direction: horizontal axis wind power generators and vertical axis wind power generators. [0003] Existing wind turbines mainly use horizontal-axis high-speed ...
