Abstract

The invention provides a blade with a delayed separation tail edge and relates to the technical field of wind power technologies. The blade with the delayed separation tail edge comprises a blade body, a box body and the delayed separation tail edge. The blade body is provided with a tip end, a root end, a front edge and a rear edge. The box body is arranged on the root end in a sleeving manner. The box body further comprises a wing fence and an end plate. The wind fence is arranged on the side, close to the root end, of the blade body in a sleeving manner. The end plate is arranged between the pressure side wall of the box body and the force suction side wall of the box body, and the delayed separation tail edge is connected to the surface of the end plate. Due to the fact that the blade is provided with the box body and the delayed separation tail edge, resistance exerted on the blade is reduced, the wind catching capability of the surface of the blade is improved, the utilization efficiency of wind energy is improved, and the power generation capability of a unit can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a delayed separation trailing edge blade. Background technique [0002] At present, the world's non-renewable energy sources tend to be exhausted, and the pollution caused by the burning of oil and coal has endangered the survival of human beings. The development and utilization of green energy has been paid more and more attention by various countries. At present, the wind power industry has started a large-scale expansion in China. In the past 10 years, China's wind power generation has developed rapidly, and its installed capacity has increased from 20,000 kilowatts in 1990 to 268,000 kilowatts in 1999. By 2010, China's wind power generation installed capacity has exceeded 5 million kilowatts. One of the countries with the most developed power generation. [0003] Wind power generation in low wind speed areas in my country has entered the stage of large-scale d...
