Embodiment 1
[0058] In this embodiment, the collector blade assembly type low-gravity high-efficiency vertical axis wind turbine is as follows: figure 1 As shown, it includes a fixed tower 1 that determines the vertical axis of rotation and a wind wheel 2 supported on the tower 1, and the wind wheel 2 and the tower 1 constitute a horizontal rotation pair that is axially constrained; the wind wheel 2 includes a center of rotation supported on The wheel frame 3 of the tower 1 and the blades distributed around the wheel frame 3; the blades include a group of alternately spaced collector blades 4 and auxiliary blades 4-1; the collector blades 4 and auxiliary blades 4-1 are vertical to the extended streamlined cross-section blades; such as Figure 11 to Figure 13 As shown, the collecting vanes 4 are composed of a group of fins 5 arranged in parallel with gaps between them; as Figure 4 As shown, the outward facing blade surface of the auxiliary blade 4-1 is concave and the inner blade surface ...
Embodiment 2
[0067] In this embodiment, the collector blade assembly type low-gravity high-efficiency vertical axis wind turbine is as follows: Figure 40 Shown, basic structure is identical with embodiment 1, and difference is only in:
[0068] (1) There are two connecting frames, which form two layers of spokes with the transmission frame. Each layer of spokes is equipped with corresponding collector blades 4 and auxiliary blades 4-1. The collector blades 4 or The auxiliary blades 4-1 are distributed in a staggered manner.
[0069] (2) The first fixing member 8 such as Figure 5 , Figure 39 Shown; The second fixing member 14 is as Figure 6 shown.
[0070] (3) if Figure 37 As shown, the support member 11 is an "X"-shaped member with four ends. The parts are located on the same side of the transmission frame and the connection frame.
[0071] (4) The structure of the transmission frame is as follows: Figure 19 As shown, the connection box structure is as Figure 35 shown.
Embodiment 3
[0073] In this embodiment, the collector blade assembly type low-gravity high-efficiency vertical axis wind turbine is as follows: Figure 41 , Figure 42 Shown, basic structure is identical with embodiment 1, and difference is only in:
[0074] (1) Between the side of the first fixing member 8 facing the transmission frame or the connection frame and the spokes of the transmission frame or connection frame, there is a telescopic controller 12 for rotating the angle of the blade; the controller 12 is an elastic component, or the controller 12 is the electric controller of the controlled end external control equipment. It should be noted that a telescopic controller 12 for rotating the angle of the blade may also be provided between the part of the second fixing member 14 close to the blade and the spoke of the transmission frame or the connection frame.
[0075] (2) if Figure 36 As shown, the supporting member 11 is a straight rod that is fixedly connected to the transmiss...
