Beveled main beam blade of wind turbine generator

The utility model discloses a beveled main beam blade of a wind turbine generator, the number of main beams of the blade is two, each main beam is formed by connecting a plurality of main beam pultrusion plates, the main beam pultrusion plates which are located in a blade tip section and close to one side of the front edge of the blade are obliquely cut towards the blade root direction at the position where a preset distance is kept between the main beam pultrusion plates and structural adhesive on the inner wall of the front edge of the blade, and the main beam pultrusion plates are arranged in the blade tip section. The width of the cross section of the main beam pultrusion plate is gradually reduced from the blade root to the blade tip, and a beveling chamfer is formed between the main beam pultrusion plate and the adjacent main beam pultrusion plate; the other main beam pultrusion plate which is positioned in the blade tip section and is close to one side of the blade rear edge is obliquely cut towards th
