Wind power blade main beam structure, preparation method thereof and wind power blade

Abstract

The invention relates to the technical field of wind power blades, and provides a wind power blade main beam structure and a preparation method thereof and a wind power blade. The wind power blade main beam structure comprises a glass plate frame, the glass plate frame is suitable for being arranged on a blade shell, the glass plate frame comprises M glass plates and N glass rods, arc-shaped grooves are formed in the ends, in the width direction, of the glass plates, a cavity is defined by the arc-shaped grooves of every two adjacent glass plates, the glass rods are embedded in the cavities, and the glass plates are suitable for rotating around the glass rods. According to the wind power blade main beam structure, the arc-shaped grooves are formed in the ends of the glass plates, and the glass rods are embedded in the cavities defined by the arc-shaped grooves of the two adjacent horizontally-arranged glass plates so that the resin enrichment phenomenon is reduced, and when the glass plate frame comprising the glass plates is suitable for being arranged on the blade shell, due to the fact that the glass plates can rotate by a small angle along with the glass rods and have the same shapes with the inner wall of the blade shell, the laying operation of the wind power blade main beam structure is more facilitated.

Description

technical field [0001] The present invention relates to the technical field of wind power blades, in particular, to a main beam structure of a wind power blade, a preparation method thereof, and a wind power blade. Background technique [0002] The main beam is an important part of the blade structure and plays an important role in the bearing capacity of the blade. However, the main beam of the blade in the prior art mainly includes a plurality of glass plates, and the two adjacent glass plates are bonded and spliced ​​by resin. Since the end faces of the glass plates have a rectangular structure, the splicing of the two adjacent glass plates is caused. There is a problem of rich resin between the seams, which affects the laying operation of the blade main beam. SUMMARY OF THE INVENTION [0003] The problem solved by the present invention is how to avoid the resin-rich problem of the main beam structure of the wind turbine blade. [0004] In order to solve the above pro...

Problems solved by technology

However, the main beam of the blade in the prior art mainly includes a plurality of glass plates, and resin is used for bonding and splicing between two adjacent glass plates. Since the end faces of the glass plates are rectangular in structure, the splicing of two adjacent glass plates Resin-rich problems appear between joints, which affects the laying operation of the main beam of the blade
