Description

[0001] The utility model relates to the technical field of wind turbine blade shaping, in particular to a jig for shaping the leading edge of a wind turbine blade. Background Art

[0002] Wind is one of the pollution-free energy sources, and it is inexhaustible. For coastal islands, grassland pastoral areas, mountainous areas and plateau areas that are short of water, fuel and have inconvenient transportation, it is very suitable and promising to use wind power generation according to local conditions. Wind power generation converts the kinetic energy of wind into mechanical kinetic energy, and then converts mechanical energy into electrical kinetic energy. Its principle is to use wind power to drive the windmill blades to rotate, and then increase the speed of rotation through a speed increaser to enable the generator to generate electricity. The blades are the core components of wind turbines. As the power requirements of wind power generation continue to increase, the size of the blades is also becoming larger and larger, causing a direct problem of inconvenience in movement.

[0003] However, we found during use that due to the large size and irregular shape of the blades, the leading edge of the blades is easily curled due to impact during installation or transportation, affecting the subsequent use of the blades. Therefore, the leading edge of the blades needs to be trimmed during installation. However, the existing trimming device does not provide ideal protection for the blades during use, and is prone to causing secondary damage to the blade surface, affecting the trimming effect.
