The anti-collision type wind power blade comprises a cylinder, a blade body is fixedly connected to the rear end face of the cylinder, straight plates are attached to the upper side and the lower side of the blade body respectively, the outer sides of the straight plates are connected with protection structures respectively, and each protection structure comprises a double-end stud, a rotating plate, a square plate, a support, a transverse rod and a shell. The outer wall of the double-end stud is rotationally connected with a notch in the outer wall of the straight plate, and the right side of the outer wall of the double-end stud is connected with the inner wall of the rotating plate in a welded mode. According to the anti-collision type wind power blade, the transverse rod drives the shell to be combined, the shell plays an anti-collision protection role, collision damage is prevented, normal use is ensured, the maintenance cost is reduced, damage to internal parts is avoided, the protection performance is ensured, danger is eliminated, supporting of the round rod is achieved, deformation caused by collision during transportation is prevented, normal installation is ensured, and practicability is improved; and the problem of connection conflict is solved, re-punching is not needed, the use difficulty is reduced, and popularization and use are facilitated.
