Wind power turbulent flow structure

Abstract

The invention belongs to the technical field of wind power generation, and particularly relates to a wind power turbulent flow structure on a wind power generation fan blade. The wind power turbulent flow structure is arranged at the end portion of the outer side of the fan blade, and a fan blade steel plate framework extends to be inserted into the wind power turbulent flow structure. The wind power turbulent flow structure comprises a wind power turbulent flow structure body and a lightning arrester arranged at the tip end of the wind power turbulent flow structure body, and the lightning arrester is connected with the fan blade steel plate framework in a communicating mode. The wind power turbulent flow structure body is of a dorsal fin structure, the windward side face is of a conical edge structure, and protruding edges and grooves which are consistent with the transverse inclination radian of the fan blade and are arranged at intervals are symmetrically arranged on the two sides of the wind power turbulent flow structure body. Ventilation holes transversely penetrating through the wind power turbulent flow structure body are formed in the side face of the wind power turbulent flow structure body. The technical problems that according to an existing wind power turbulent flow structure, the air supply amount cannot be increased under the condition that wind power is too small, wind resistance cannot be increased under the condition that wind power is too large, fan blades rotate too fast and are damaged are solved.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a wind spoiler structure on wind blades of wind power generation. Background technique [0002] The blades of wind turbines are key components for wind power equipment to convert wind energy into mechanical energy, and their manufacturing costs account for about 15% to 30% of the total cost of wind turbines. The blade usually presents a unique airfoil based on the aerodynamic shape design. The greater the lift-to-drag ratio of the blade of the airfoil, the better the wind capture efficiency of the fan, and thus the output power of the fan. However, when the wind-catching efficiency of the blades is improved, if the wind is too strong, it is easy to cause the fan speed to be too fast, and the activation of the brake assist system will cause great damage to the equipment. Good wind compensation ability, and at the same time, a wind spoiler structure that ...
