People use wind energy. At present, the common wind turbine is the horizontal axis wind turbine, that is, the blades are driven by the wind to rotate around the horizontal axis. The most common horizontal axis wind turbine is the horizontal axis propeller wind turbine. This technology is now very Mature, but the horizontal axis propeller wind turbine has very strict requirements on the material of the blades. In fact, the wind turbine blades imported by some advanced countries are made of carbon fiber reinforced resin under very strict conditions, which are expensive. As a vulnerable product, the blade further causes the disadvantage of high cost, thus limiting the propeller type Widespread application of wind turbines. In addition, the propeller-type wind turbine must have a machine head and a tower due to its structure. The nose and tower in the area scanned by the fan blades will inevitably affect the full use of wind energy, resulting in the propeller-type wind turbine near the center. The utilization rate of wind energy is low, so that the already limited wind interception area brings unavoidable further loss of wind energy, and the utilization coefficient of wind energy is low.
