A method for preparing wind power blades to control the mass distribution of wind power blades

Abstract

The invention belongs to the technical field of non-metal composite material processing and forming, and mainly relates to a wind power blade preparation method for controlling the mass distribution of wind power blades. The proposed method for preparing a wind turbine blade for controlling the mass distribution of a wind turbine blade includes the preparation of the upper shell of the blade, the preparation of the lower shell of the blade, the preparation of the leading edge web, the preparation of the trailing edge web, the preparation of the girder and the blade joint. Die bonding and forming; through the preparation of the upper shell of the blade, the preparation of the lower shell of the blade, the preparation of the leading edge web, the preparation of the trailing edge web, the preparation of the girders and the blade clamping and bonding process weight and quality Distribution control, so as to complete the control of wind power blade mass distribution. The invention enables the final mass distribution of the blade to be controlled within a certain range, avoids or reduces the single-point counterweight in the later stage of the blade, and reduces the quality and safety risks of the single-point counterweight.

Description

technical field [0001] The invention belongs to the technical field of processing and forming of non-metallic composite materials, and mainly relates to a method for preparing wind power blades for controlling the mass distribution of wind power blades. Background technique [0002] Wind power blades are installed on the hub of the whole machine, and under the action of the wind, the generator is driven to generate electricity; at present, large-scale horizontal axis wind turbines are divided into several types according to the number of blades, such as single blade, double blade and three blades, among which three The wind energy utilization efficiency of blades is the highest. At present, the wind power market basically adopts three-blade wind turbines; since three blades need to be used together in a set, in order to ensure the overall structural stability of the wind turbine and prevent additional wear of the main shaft, it is necessary to use a complete set of wind turbi...

Problems solved by technology

[0005] In view of the current technical status of the complete set of counterweights for wind turbine blades, the material of the blade counterweights cannot improve the overall strength of the blades, but will increase some quality and safety risks. The purpose of this invention is to propose a method for controlling the quality of wind turbine blades The distributed wind power blade preparation method controls the blade mass distribution during the blade production process, so that the blade can be produced without counterweight or with very little counterweight to achieve the purpose of matching; at the same time, the counterweight material is converted into a pair of blades The reinforcing layer that contributes to the strength and strength reduces the risk of impacting the quality and safety of the blade in the "centralized weight" mode in the current process
