Problems solved by technology

The efficiency of fan blades determines the efficiency of wind turbines. Traditional wind power blades mostly adopt a three-piece fan structure. The entire blade has a certain bending and twisting. Although the structure is simple, it has low efficiency, especially the low efficiency of the blade tip. Therefore, it is imminent to develop a fan blade with relatively simple structure, light weight, good maintai

Abstract

The invention discloses a wind power blade with a specially-made blade tip plate. The invention relates to the wind power blade with the blade tip plate, and belongs to the field of wind power generation and high-end manufacturing. The blade tip plate is fixed at the tail end of the wind power blade, the fixed connection positions of the blade tip plate and the wind power blade is perpendicular toeach other, the blade tip plate bends outwards in an arc shape from the connection position of the blade tip plate and the wind power blade to two sides, the thickness of the blade tip plate is gradually reduced from the windward side to the other side, the edge of the windward side is arc-shaped, and the edge of the other side is sharp. When the wind power blade with the blade tip plate is applied to an existing wind power engine, the airflow capture area is increased, blade tip backflow of the wind power blade is basically eliminated, blade rotation induction resistance caused by vortex shedding of blade tip backflow is reduced, the rigidity of the blade, especially the rigidity of the blade tip, is increased through centrifugal force generated by rotation, the weight is reduced, and the efficiency of a wind driven generator is higher.

Description

technical field [0001] The invention relates to a wind power blade with a special blade tip plate, which belongs to the technical field of wind power generation. Background technique [0002] With the development of science and technology and the improvement of actual demand, people have higher and higher requirements for the efficiency of aircraft wind power generation system. The core of wind power generation and aeroengine fans is the fan blade. The efficiency of fan blades determines the efficiency of wind turbines. Traditional wind power blades mostly use a three-piece fan structure. The entire blade has a certain degree of bending and twisting. Although the structure is simple, it has low efficiency, especially the low efficiency of the blade tip. Therefore, it is imminent to develop a fan blade with relatively simple structure, light weight, good maintainability and high efficiency. [0003] At present, the structure of the fan blade is a three-piece fan structure, a...
