Folding type blade wind power generation device

Abstract

The invention discloses a folding type blade wind power generation device. The folding type blade wind power generation device aims at automatically adjusting the size of the stress area of blades in the wind power generation device according to different wind speeds, it is guaranteed that the wind power generation device normally works under the strong wind condition, and it can be guaranteed that the wind power generation device fully utilizes wind energy under the low wind condition. A fixed blade is fixedly connected with a blade mounting shaft and fixedly connected with a blade pin shaft, and a movable blade and the fixed blade are movably mounted in a matching manner through the blade pin shaft. The blade pin shaft is sleeved with a reset spring, the reset spring is movably mounted in a spring mounting groove in a matched manner, and a centrifugal hammer stop lever is movably mounted on the fixed blade through a centrifugal hammer pin shaft. A movable blade limiting body is arranged on the movable blade, the centrifugal hammer pin shaft is sleeved with a centrifugal hammer stop lever reset spring, and the centrifugal hammer stop lever is pressed into the position, with the smallest space, in the movable blade limiting body through the centrifugal hammer stop lever reset spring. The folding type blade wind power generation device is suitable for rotating speed adjustment of the wind power generation device, the braking function is relieved, and energy is saved.

Description

technical field [0001] The invention relates to a wind power generating device, in particular to a folding blade wind power generating device. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge, and the global wind energy is about 2.74×10 9 MW, of which the available wind energy is 2×10 7 MW is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. At present, the energy obtained by burning coal in the world every year is only one-third of the energy provided by wind power in a year. Moreover, wind power generation has no fuel problem, nor does it produce radiation or air pollution, and it is a particularly good way of generating electricity. Therefore, both at home and abroad attach great importance to the use of wind power to generate electricity, and wind power generation is mainly realized by wind power g...

AI Technical Summary

Problems solved by technology

The braking device of the existing wind power generation device is expensive, difficult to maintain, the control circuit is complicated, and it also consumes a certain amount of electric energy

At present, there is no blade that can automatically adjust the wind receiving area in domestic wind power generation devices.
