Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiment is only one of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032] A method for pre-embedding a megawatt-level wind power blade root screw, the method comprising the following steps:

[0033] (1) Install the blade root flange: align the center of each flange hole of the blade root flange with the center of each hole of the mold flange;

[0034] (2) Install embedded screws and nuts: insert a corresponding number of embedded screws into the flange holes of the blade root flange and fix them with nuts;

[0035] (3)...

Abstract

The invention provides a method for pre-buried screw processing method for blade roots of Megawatt-level wind turbine generator set. The method includes the steps of aligning the center of each flange hole of a blade root flange plate to corresponding center of each hole of a flange die; penetrating pre-buried screws into the flange holes of the blade root flange plate and fixing the pre-buried screws with nuts; nesting the pre-buried screws with UD sleeves; penetrating bolt sleeves into the UD sleeves; penetrating the pre-buried screws into the bolt sleeves to be tightened; penetrating threaded ends of the bolt sleeves into PVC (Poly Vinyl Chloride) wedges ; clamping the PVC chocks on the lateral sides of the UC sleeves and compacting the UD sleeves and the PVC chocks; and placing UD sticks in the inner sides of the US sleeves, filling the UD sticks between neighboring bolt sleeves, pounding the US sticks tight, and filling clearances among the UC sleeves, the UD sticks and the bolt sleeves with the UD sticks. By the aid of the method, technological process is shortened, rate of finished products is increased, working position is reduced, and production efficiency is improved; and further wind turbine generator set the pre-buried screws and the wind turbine generator set are combined tightly.

Description

technical field [0001] The invention relates to the field of manufacturing wind power blades, in particular to a process method for pre-embedding a blade root screw of a megawatt wind power blade. Background technique [0002] As the core component of the wind turbine blade, the blade technology is one of the core technologies of the wind power generation system. Its performance directly affects the wind energy efficiency of the wind turbine unit and the load on the unit, and determines the overall performance of the unit and the wind power to a large extent. Economics of development and utilization. At the same time, the blade is also the core component of the wind turbine, and its cost is about 23% of the total cost of the wind turbine. [0003] The existing blade technology usually adopts vacuum infusion molding, and the root of the blade needs to be cut and punched later. This makes the process of forming the blade complicated, and the blade root cutting and punching o...
