Embodiment Construction

[0030] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some 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 making creative efforts belong to the protection scope of the present invention.

[0031] like figure 1 As shown, the present invention provides a method for controlling the wrinkling of the end face of the embedded wind turbine blade, comprising the following steps:

[0032] 1) Lay the outer surface cloth layer 6 on the blade root forming surface 5 of the blade root flange 1. After the blade root pre-embedded component 4 is placed on the blade root flange 1, the Place the blade root extension flange 2, adjust the outer surface cloth layer 6...

Abstract

The invention provides a controlling method of folds of an end face of a blade root of a pre-embedded type wind-power blade, and relates to the technical field of wind-power blades manufacturing. Thecontrolling method of the folds of the end face of the blade root of the pre-embedded type wind-power blade comprises the following steps that (01) a blade root extension flange blank is manufactured,(02) the blade root extension flange blank is subjected to trim, (1) a blade root extension flange is placed, (2) a blade root pre-embedded assembly is subjected to treatment, (3) cloth layers of theblade root extension flange is trimmed, (4) folds of a blade root prefabricated component are reworked, (5) and the blade root prefabricated component is formed in vacuum. The controlling method of the folds of the end face of the blade root of the pre-embedded type wind-power blade is novel and efficient, has convenient and fast operation, and has the function of removing the folds of the clothlayers of the two end parts of the blade root caused by the type-following performance of wedge-shaped strips and a molded surface.

Description

technical field [0001] The invention relates to the technical field of wind power blade manufacturing, in particular to a method for controlling wrinkles on the root end surface of a pre-embedded wind power blade. Background technique [0002] With the advancement of national energy conservation and emission reduction policies, green and environmentally friendly energy is the key development direction in the future. Wind energy has the advantages of low energy consumption, environmental protection, and large reserves, and has become a key energy source for development at home and abroad. A wind turbine is a device that converts wind energy into electrical energy. The blade is one of the core components of the wind turbine. In the production process of the blade, the blade forming process is the most important forming process. The quality of the root forming directly affects the service life of the blade. Therefore, it plays a vital role in the quality of the blade. [0003]...
