Abstract

The embodiment of the invention provides a manufacturing method of a web plate for a fan blade. The manufacturing method of the web plate for the fan blade comprises the steps that fiber reinforced composite materials are used for manufacturing a plurality of web plate modules, each web plate module comprises a flat plate body and a plurality of reinforcing components, and the reinforcing components are connected with the flat plate body; and the web plate modules are connected together to form the web plate for the fan blade. According to the manufacturing method of the web plate for the fan blade, the web plate structure without a core material can be modularly manufactured, the cost is saved, and the occupied area of a workshop is reduced.

Description

Technical field [0001] Embodiments of the present invention relate to the field of wind power, and more particularly to a method for producing a wind turbine blade. Background technique [0002] With the gradual depletion of energy such as coal, oil, humans pay more attention to the use of renewable energy. The wind energy is increasingly attached to the world as a clean renewable energy source. For coastal islands, grassland pastoral areas, mountainous areas, grassland pastoral, mountains and plateau, which are well-used, is very suitable for local conditions, which is very suitable for local conditions. Wind power generation means that the kinetic energy of the wind turbine is converted into electrical energy. [0003] With the development of the wind power industry, the demand of the electric power unit is getting lower and lower. The fan blade is a core component of a wind turbine, and the weight loss of the fan blade is of great significance. In the cost of fan blade, the mo...
