Wind rotor of horizontally rotating type wind generating set

Abstract

The invention relates to a wind rotor of a horizontally rotating type wind generating set, which is characterized by comprising four rotor blades (1), wherein the adjacent included angle of the rotor blades (1) is 90 degrees; the cross section of each rotor blade is in a Y shape; and the Y-shaped blade is provided with an elastic band (7) positioned on a horizontal surface and two blades (8a and 8b) which are symmetrical relative to the horizontal surface. The wind generating set of the invention omits two components: a horizontal tail fin and a horizontally rotating rolling bearing; and because the horizontally arranged blades also have the function of the tail fin, the blades can face wind from any directions in 360 degrees and rotate to generate electricity, thereby greatly improving the working efficiency of the wind generating set. The invention features simple structure, easy preparation, high rotating efficiency and low production cost.

Description

Technical field: [0001] The invention relates to a wind power generating equipment, and further relates to a wind rotor of a horizontally rotating wind power generating set. technical background: [0002] With the continuous development of economy and society, energy, environment and information have become the three major themes of scientific and technological development in the 21st century. People's demand and attention to clean and renewable new energy are increasing day by day. Wind power is one of the renewable clean new energy sources. Because of its safety, reliability, low cost, convenient use, cleanliness, and environmental protection, it has been highly valued by people in recent years. [0003] The blades of conventional wind power generators are placed vertically, with a horizontal empennage and rolling bearings that can rotate the generator casing horizontally by 360° in structure. The function of these two components used in conjunction is mainly to make the ...

AI Technical Summary

Problems solved by technology

But in many cases, such as: the wind is too small or the rolling bearing is corroded, rusted, etc., the horizontal tail does not work, the rolling bearing has too much resistance to rotation or cannot rotate at all

At this time, the blades cannot meet the wind direction, so they cannot rotate (or the speed is slowed down), which greatly affects the power generation efficiency of the motor, or cannot generate electricity at all.

The investigation in a wind power generator test field shows that there are 50 wind power generators in the test field, and after three years of use, the blades of 18 generators cannot rotate, and the damage rate is as high as 36%. The main problems are caused by the above two factors. failure of a component
