Abstract

The invention relates to the technical field of wind power generation equipment, in particular to a wave airfoil blade and a wind turbine. A plurality of wave crests and wave troughs are continuouslyarranged at the front edge in the stretching direction of the wave airfoil blade. A column body is connected between every two adjacent wave crests. The axial direction of each column body is the sameas the stretching direction of the wave airfoil blade. The cross section area of each column body is far less than that of the face, opposite to the column body, of each wave crest. According to thewave airfoil blade, the structure is more stable and firmer, rigidity is higher, vibration of the wave crests caused by strong incoming flow can be stably controlled, abrasion of sand particles and other materials in the incoming flow to the wave troughs of the wave airfoil blade can be prevented, and the aerodynamic performance of the blade can be greatly improved.

Description

technical field [0001] The present application relates to the technical field of wind power generation equipment, in particular to a wave airfoil blade and a wind turbine. Background technique [0002] With the reduction of energy reserves, the development of new energy is the main trend of development, and wind energy as a clean energy has become the main development object. However, at present, the cost of developing wind power generation is higher than that of traditional energy and other new energy sources, so that wind power cannot be widely used. In maintenance, the blade is the core component of the wind turbine. The performance of the blade directly affects the power generation efficiency of the entire wind turbine. Improving the power generation efficiency of the wind turbine is equivalent to improving the price competitiveness of wind power generation. It improves its cost performance and reduces its cost in a disguised form. Therefore, in order to improve the pr...
