Abstract

The invention discloses a strip piece, a manufacturing method of the strip piece, a beam, a manufacturing method of the beam, a blade and a wind generation unit. The strip piece is of a prismatic structure and comprises a first side surface and a second side surface which are oppositely arranged and limit the thickness of the strip piece with each other, and a first groove which is formed in the first side surface in the thickness direction in a concave mode and extends in the length direction of the first side surface, and the width of the groove bottom surface of the first groove is greaterthan or equal to the width of the second side surface. According to the strip piece, when the strip piece is stacked, an embedded structure can be formed, the overall stability and strength of the stacking structure are increased, and the load bearing capacity of the overall structure is improved.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a strip and its manufacturing method, a beam and its manufacturing method, a blade and a wind turbine. Background technique [0002] With the continuous development of wind power technology, it has become a development trend in the industry to provide wind turbines with higher power and stable operation. On the one hand, high-power wind turbines will make the blades longer and longer. The increase of blade length puts forward new requirements for blade structure design. [0003] Wind turbine blades usually consist of upper and lower shells to form the outer contour, and the internal beam-web structure is used for load bearing, and the beam is the main load-bearing component. With the increase of blade length, the load borne by the beam is also increasing, and the requirements for the bearing capacity of the beam are also getting higher and higher. As a beam structure, plate...
