Embodiment Construction

[0034] Embodiments of the present invention are described in detail below:

[0035] like figure 1 As shown, a tower of a wind power generator includes an upper tower 12 and a lower tower 22. The top of the lower tower 22 is dug downward to form an accommodation cavity 220, and the upper tower 12 is partially extended into the In the accommodation chamber 220, and the accommodation chamber 220 is provided with a lifting mechanism 222 for vertically moving the upper tower 12, and the lifted upper tower 12 is detachably fixedly connected with the lower tower 22, The lower tower 12 and the lower tower 22 are partially socketed after moving down.

[0036] The tower of the wind-driven generator is divided into two parts, the upper tower 12 and the lower tower 22. Under normal circumstances, the upper tower 12 and the lower tower 22 are reliably fixed and connected to ensure the normal operation of the wind-driven generator; figure 2 As shown, when a typhoon strikes, the lifting m...

Abstract

The invention discloses a wind generator and a tower drum thereof. The wind generator comprises at least two blades and the tower drum, wherein the tower drum comprises an upper tower drum and a lower tower drum, a containing cavity is excavated in the lower tower drum from the top of the lower tower drum downwards, a part of the upper tower drum is stretched into the containing cavity, a lighting mechanism used to vertically move the upper tower drum is arranged in the containing cavity, the upper tower drum after being lifted is fixedly connected with the lower tower drum in detachable mode, and the upper tower drum after being moved downwards is connected with the a part of the lower drum cylinder in nesting mode. When a typhoon hits the wind generator, a clamping portion cooperates with the blade after being sunk after a mechanical arm is stretched out, and due to the fact that the wind generator is of a mechanical structure, the clamping portion can reliably and firmly grasp the blades, wind power is blown from the back of each blade to two sides of each blade, and the upper tower drum, the lower tower drum and the blades can form a trinity structure, and therefore the wind power on the upper portion of the tower drum can be further reduced, and typhoon resistance ability of the upper portion of the wind generator and the whole wind generator is enhanced.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power generator and a tower 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. [0004] At present, in order...
