The invention relates to the field of wind power generation, in particular to an extended blade of a wind power generator and a manufacturing method thereof, which includes a blade body and an extension section, a connecting section is arranged between the blade body and the extension section, and two ends of a first liner are respectively connected to a first The trailing edge core material and the second trailing edge core material, the two ends of the second liner are respectively connected to the first leading edge core material and the second leading edge core material, and the two ends of the reinforcing cloth are respectively connected to the first trailing edge beam and the second The trailing edge beam and the first main beam and the second main beam. The invention connects the first trailing edge beam and the second trailing edge beam and the first main beam and the second main beam through the reinforcing cloth, which can minimize the impact on the strength of the blade and improve the strength and stability of the extended blade. The plates respectively connect the trailing edge core material and the leading edge core material, which can further improve the strength and stability of the extended blade.
Description
technical field [0001] The invention relates to the field of wind power generation, in particular to an extended blade of a wind power generator and a manufacturing method thereof. Background technique [0002] The power generation efficiency of wind turbines is an important factor considered by each wind farm. How to improve the efficiency of each wind generator as much as possible is what those skilled in the art need to consider when building a wind farm. The wind turbine mainly relies on wind turbine blades to capture wind energy, and the length of the wind turbine blades directly affects the ability of the wind turbine to capture wind energy and the output power of the wind turbine. Increasing the length of wind turbine blades at low wind speeds can effectively increase the power generation of wind turbines. Therefore, the blades of newly developed wind turbines are getting longer and longer, but the blades of wind turbines that have been in service in the early days a...
