Description
Technical Field
The embodiment of the invention relates to the technical field of wind power, in particular to a manufacturing method of a web plate for a fan blade.
Background
Along with the gradual exhaustion of energy sources such as coal, petroleum and the like, people pay more attention to the utilization of renewable energy sources. Wind energy is becoming increasingly important worldwide as a clean renewable energy source. The wind power generation device is very suitable for coastal islands, grassland pasture areas, mountain areas and plateau areas which are lack of water, fuel and inconvenient in transportation, and can be widely used according to local conditions. Wind power generation means that kinetic energy of wind is converted into electric energy by using a wind generating set.
With the development of the wind power industry, the requirements on the electricity price of the wind generating set are lower. The fan blade is used as a core component of the wind generating set, and the weight and cost reduction of the fan blade has important significance. Among fan blade costs, mold costs are a significant proportion. The fan blade typically includes a blade shell and a web disposed within the blade shell for supporting the blade shell. The web serves as a key component of the fan blade and plays roles in supporting the main beam and transmitting shear force. The webs used in existing fan blades typically employ a sandwich structure. Currently, the main current domestic modes include a double web sandwich structure and a single web sandwich structure. However, in both the double web sandwich structure and the single web sandwich structure, the web used in the fan blade is generally formed integrally by using a web mold, and the fiber cloth and the core material are laid on the web mold, vacuum poured and cured by heating. However, this form of using web dies would undoubtedly increase die cost and also increase plant footprint.
