Problems solved by technology

[0002] The existing large-scale wind power generation blades are narrow and small, with high single-piece efficiency but low overall efficiency; even so, the bending force borne by the main rod not only increases with the square of the blade length, but also doubles with the height of the rod. It becomes an expensive tower; and when the wind is crazy, the angle of the blade can be adjusted, which will greatly reduce the strength of the blade, greatly increase the difficulty of blade manufacturing, greatly increase the difficulty of self-control, and greatly increase the cost of wind power generation
At the same time, it only blindly develops towards the high altitude and blindly avoids the ground between adjacent wind turbines, so that the wind near the surface and the wind near the water surface do not play much role

Embodiment Construction

[0025] The present invention is composed of devices such as a gradually shrinking and expanding air duct, an air duct frame 1, 5 sets of wind power generators, and a running track.

[0026] The air duct of the novel wind power generation device of the present invention is a gradually retracting and expanding type, and the gradually retracting type is the main type.

[0027] The mouth surface of the air duct is slightly raised about 10 degrees, and a main shaft 9 with a thin upper part and a thicker lower part is provided vertically downward from the center of the top to support the dome. The main shaft 9 outer cover in the air duct is a streamlined casing that is fixedly connected with the upper and lower frames 1.

[0028] Rotating wheels 13 are arranged on both sides of the frame 1 below the main shaft 9 of the novel wind power generating device of the present invention.

[0029] The part of the main body of the air duct near the ground and extending forward from the water ...

Abstract

The invention relates to a novel wind power generator, which consists of a gradually-extending and gradually-reducing type air passage, an air passage framework, a wind power generator and an operation rail, wherein a movable flow division and flow guide window is arranged in the middle of the air passage. The novel wind power generator sufficiently realizes the effects of near ground wind and near water surface wind, and belongs to a major technology for developing wind power generation.

Description

technical field [0001] The invention belongs to the technical field of wind power generation. Background technique [0002] The existing large-scale wind power generation blades are narrow and small, with high single-piece efficiency but low overall efficiency; even so, the bending force borne by the main rod not only increases with the square of the blade length, but also doubles with the height of the rod. It has also become an expensive tower; and when the wind is crazy, the angle of the blades can be adjusted to greatly reduce the strength of the blades, greatly increase the difficulty of blade manufacturing, greatly increase the difficulty of self-control, and greatly increase the cost of wind power generation. Simultaneously only blindly develops towards the high altitude but blindly avoids the ground between the adjacent wind turbines, does not allow near-surface wind and near-water surface wind to play much effect.
