Anti-vortex device for a wind turbine blade and installation method thereof

A method of installing an anti-vortex device for a wind turbine blade, comprising:

• arranging a plurality of first binding strap assemblies sequentially along an extension direction of the wind turbine blade within a blade tip region of the wind turbine blade;
• installing a first spoiler block on each of the plurality of first binding strap assemblies;
• arranging a plurality of second binding strap assemblies at intervals sequentially along the extension direction of the wind turbine blade within a target region of the wind turbine blade, wherein the target region is between the blade tip region and a blade root of the wind turbine blade;
• and
• connecting the plurality of first binding strap assemblies to the plurality of second binding strap assemblies using at least one first connecting member, with one end of each of the at least one first connecting member connected to the blade root of the wind turbine blade.
