Wind turbine generator blade rigidity improving device

The utility model discloses a wind turbine generator blade rigidity improving device which comprises a base, a tower is fixedly arranged at the top of the base, a hub is movably arranged on one side of the top end of the tower through a bearing, a plurality of blade bodies are evenly arranged on the outer side of the hub, and a first supporting rod is fixedly arranged at the end, away from the tower, of the hub. Through the arrangement of the pull rods, pull force opposite to wind thrust can be provided for the two ends of the surface of the blade body; the rigidity of the blade surface is effectively improved; the first reinforcing rods arranged between the pull rods can form a plurality of triangular stable supporting structures between the pull rods; the connecting strength between thepull rods is improved, the situation that the blade body is bent and collides with a tower due to the fact that the rigidity is not enough when the blade body rotates is effectively avoided, the use stability of the wind turb
