Ventilator turbine of wind power generator set

Abstract

The wind turbine for wind generator includes one central shaft, one fixing ring, two steel pipe axles to connect the ring to the central shaft, wind impellers capable of rotating around the shaft on the steel pipe axles, and driving mechanism on the wind impellers. The wind turbine has the advantages of great thrust coefficient, great output power and relatively low cost.

Description

technical field [0001] The invention relates to a wind power generator, in particular to a wind turbine of a wind power generating set. Background technique [0002] With the development of society, electricity occupies an increasingly important position in our daily life, and various power generation methods have emerged as the times require, mainly including wind power, hydropower and thermal power. The current wind generators basically use paddle-type wind blades. When using wind power generation, due to the small thrust coefficient, the wind blades need a large wind speed during the start-up stage, but the wind resistance is poor, and the wind speed reaches a certain level. It is easy to damage the wind blades, the available wind speed line segment is small, and the output power is small; and in order to meet the demand for electricity, the existing generators are basically large, so for wind power generators, its blade volume It is also very large, difficult to manufac...

Problems solved by technology

The current wind generators basically use paddle-type wind blades. When using wind power generation, due to the small thrust coefficient, the wind blades need a large wind speed at the start-up stage, but the wind resistance is poor, and the wind speed reaches a certain level. It is easy to damage the wind blades, the available wind speed line segment is small, and the output power is small; and in order to meet the electricity demand, the existing generators are basically large, so for wind power generators, its blade volume It is also very large, difficult to manufacture, and the materials are relatively expensive

[0003] The utility model specification of patent No. ZL01266082.5 discloses a fan blade of a wind power generator, which is a telescopic adjustment rod corresponding to the fan blade pivotally arranged on the outer section of the operation axis of the fan blade on the wind power generator set. The other end of the telescopic adjustment rod is pivotally connected to the middle section of each fan blade; the advantage is that the tilt direction angle of the fan blades is adjusted by the telescopic adjustment rod to adapt to the change of wind direction. When running in the wind, the generator set also changes direction with a small angle to avoid fan The blades are damaged due to oblique wind force; and the outer end of the fan blades is designed as a pointed structure that is easy to attract lightning waves in the air, which can achieve the lightning protection effect of introducing lightning in the air to the ground; but it also does not solve the problem of low output power and available The problem of small wind speed line segment
