Spiral vortex blade and spiral vortex wind driven generator

Abstract

The invention discloses a spiral vortex blade which comprises multiple blade bodies. The blade bodies are distributed in a circumferential array manner. The front view curve of each blade body is in a spiral vortex shape. All the blade bodies are fixedly connected with a draught fan rotating shaft through the center portions of the blade bodies. The invention further discloses a spiral vortex wind driven generator which comprises the blade, a generator cabin, the draught fan rotating shaft, a steering rudder plate and a fixing piece. The draught fan rotating shaft is connected with the power input end of one side of the generator cabin. The steering rubber plate is fixed to the generator cabin. The plate face of the steering rubber plate is arranged in the direction opposite to the draught fan rotating shaft. The fixing piece is connected with the generator cabin. The spiral vortex blade is applied to the wind driven generator, and more wind energy can be obtained under the same wind weeping area. The whole spiral vortex wind driven generator is convenient to mount, the size is small under the same capacity power, a draught fan start wind speed is low, draught fan design is ingenious, the appearance is novel and attractive, the overall mechanical strength is high, and wind resistance is good; and at present, the spiral vortex blade and the spiral vortex wind driven generator have passed the wind tunnel test, and the wind energy utilization efficiency Cp value can reach over 0.7.

Description

technical field [0001] The invention relates to the field of wind power generation equipment, in particular to a spiral vortex wind power generator with high power generation efficiency and a spiral vortex wind blade of the spiral vortex wind power generator. Background technique [0002] It is estimated that by 2020, the world's wind power generation capacity will account for 12% of the total electricity. my country has a long coastline, vast coastal areas, and areas rich in wind resources. It is endowed with unique advantages in regional wind energy resources. my country is rich in wind energy resources, with a reserve of 3.2 billion kilowatts and a developable installed capacity of 250 million kilowatts, ranking first in the world. At present, the proportion of wind power in my country is far lower than that in Europe, and the potential for wind power generation is huge. [0003] Traditional wind turbines use rotor-type wind blades with a solidity of less than 8%, which i...
