Wind driven generator and typhoon-resisting method thereof

Abstract

The invention discloses a wind driven generator and a typhoon-resisting method of the wind driven generator. The wind driven generator comprises a tower drum and two blades fixed to the upper end of the tower drum. A rotating driving mechanism drives the blades to be perpendicular or parallel to the tower drum, and a telescopic mechanical arm is arranged on the side wall, corresponding to the blades, of the tower drum; a clamping portion is arranged at the front end of the mechanical arm, and after the mechanical arm stretches out, and the blades are parallel to the tower drum, the clamping portion can clamp the blades. When the typhoon rises, the rotating driving mechanism drives the blades to rotate, and therefore the blades are in the state of being parallel to the tower drum; then, the mechanical arm stretches out, the clamping portion clamps the blades, and the blades are clenched to enable the blades and the upper portion of the tower drum to form an integral structure; wind borne by the blades is conducted to the foundation of the tower drum through the mechanical arm, and therefore the blades and the upper portion of the tower drum mutually reinforce the typhoon resisting capacity; the wind is blown away from the two sides of the tower drum, and the wind of the upper portion of the tower drum is further relieved, so that the typhoon-resisting capacity of the upper portion and the whole body of the wind driven generator is reinforced.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power generator and a typhoon-resistant method thereof. Background technique [0002] At present, wind power has become the fastest growing renewable clean energy, especially offshore wind power with high wind speed, stable wind force, less wind shelter and interference, and large power generation. It is an inevitable trend for future wind power development to shift from land to sea. [0003] Unlike the relatively calm environment of the North Sea in Europe, a pioneer in the development of offshore wind power, my country's offshore wind power is threatened by typhoons every year. The typhoon "Sangmei" in 2006 and the super typhoon "Wamasun" in 2014 caused the collapse of multiple wind turbines in the Cangnan Wind Farm in Zhejiang, the Wenchang Wind Farm in Hainan, and the Yongshi Wind Farm in Zhanjiang Xuwen, causing significant investment losses.

AI Technical Summary

Problems solved by technology

The typhoon "Sangmei" in 2006 and the super typhoon "Wamasun" in 2014 caused the collapse of multiple wind turbines in Cangnan Wind Farm in Zhejiang Province, Wenchang Wind Farm in Hainan Province and Yongshi Wind Farm in Zhanjiang Xuwen, causing significant investment losses

[0007] It can be seen that both of the above two schemes have certain limitations, which are not convenient for comprehensive promotion and application.
