Embodiment 1

[0035] see Figure 1-8 As shown, a wind power generation device includes: a windmill assembly 200, and the windmill assembly 200 includes:

[0036] Spindle 10,

[0037] The first driving assembly is used to drive the rotating shaft 10 to rotate, the first driving assembly is installed on the end of the rotating shaft 10,

[0038] The second driving assembly 20 is used to drive the rotating shaft 10 to rotate, and the second driving assembly 20 is installed on the rotating shaft 10 along the axis of the rotating shaft 10 ,

[0039] Wherein, the first driving assembly includes a turntable 30 connected to the end of the rotating shaft 10 and coaxial with it. A connecting rod 31 is connected around the rotating disk 30. The axis of the connecting rod 31 is perpendicular to the axis of the rotating shaft 10. The first blade 40 is connected to the connecting rod 31. , the first vane 40 has a first assembly hole 41 for assembling with the connecting rod 31 , and one side of the first...

Embodiment 2

[0053] The connecting rod 31 of the present invention is a cylindrical rod, which is arranged around the annular side of the turntable 30, and the angle between the connecting rods 31 is 60°, of course it can also be 120°, but the angle between the connecting rods 31 should be equal. The guide vanes 23 are bent plate-shaped, and the bending angle is between 75° and 135° to realize the drainage of the wind. They are fixedly connected by bonding or welding, and the first vane 40 is interference fitted with the connecting rod 31 through the first assembly hole 41, and welding can be performed if necessary.

Embodiment 3

[0055] When the wind power generation device of the present invention is actually used: the first drive assembly is driven by the wind to generate rotational motion, which drives the rotating shaft 10 to rotate, and then increases the rotational speed through the speed increaser to make the generator 400 generate electricity. In the process of wind power generation, the first The second driving assembly 20 captures the wind of different wind directions, and further captures the spiral backward wind formed by the first driving assembly for a second time, and guides the wind flowing through the second driving assembly 20 to make it flow along the guide vanes. 23 flows into the second driving assembly 20, and forms an annular wind flow to drive the second blade 52 of the second driving assembly 50 to rotate, so as to increase the rotation speed of the rotating shaft 10 and realize the speed-up effect.

[0056] In order to test the stress situation of the first blade 40, the presen...

Abstract

The invention discloses a wind power generating device and belongs to the technical field of wind power generating equipment. The device comprises a windmill assembly which comprises a rotating shaft,a first driving assembly and a second driving assembly, wherein the first driving assembly is used for driving the rotating shaft to rotate, and installed on the end portion of the rotating shaft; the second driving assembly is used for driving the rotating shaft to rotate, and installed on the rotating shaft along the axis of the rotating shaft; the first driving assembly comprises a rotating disk connected and coaxial with the end portion of the rotating shaft, and the rotating disk is connected with connection rods in an encircled manner; the axes of the connection rods are perpendicular to the axis of the rotating shaft; a first blade is connected to each connection rod, and is provided with a first assembling hole assembled with the connection rod; and one side face of each first blade is provided with an arc-shaped concave face. The wind power generating device adopts multi-stage wind guiding, so that flowing along a preset direction forms the wind direction, and wind power is enhanced; wind energy capturing is widened, the single-machine power generating capacity is effectively improved, and the device is high in overall stability and safety.

Description

technical field [0001] The invention belongs to the technical field of power generation equipment, and in particular relates to a wind power generation device. Background technique [0002] Wind power generation is forming an upsurge in the world. Wind power generation is very popular in Finland, Denmark and other countries, and my country is also vigorously promoting it in the western region. Because wind power has no fuel problems, nor does it produce radiation or air pollution, it is a particularly good way to generate electricity. The principle of wind power generation is to use the wind to drive the blades of the windmill to rotate, and then increase the speed of rotation through the speed increaser to drive the generator to generate electricity. [0003] With the continuous maturity of wind power generation technology and the continuous reduction of power generation costs, wind power generation has become one of the most important sources of electric energy consumed b...
