The invention relates to a novel blade-shaped hemispherical wind-driving bird-dispersing apparatus. The blade-shaped hemispherical wind-driving bird-dispersing apparatus comprises a stainless steel supporting rod of the wind-driving bird-dispersing apparatus, wherein multiple hemispherical cambered stainless steel blades are installed at the top of the stainless steel supporting rod and rotate around installing points up and down; screw threads are formed on the middle part surface of the supporting rod and screwed with nuts, horizontal fin frame bars are symmetrically and fixedly arranged at two sides of each nut, fins with a certain angle formed by a plane and a horizontal direction are fixedly arranged at the outer end of the fin frame bar, a concave clamping slot opened towards the left is formed in the bottom of the supporting rod, and bolts penetrating through the bottom of the clamping slot are used for fixing the supporting rod. The bird-dispersing apparatus is simple in working principle and adopts wind power as a power source; the difference of the bird-dispersing apparatus is that the blade-shaped hemispherical wind-driving bird-dispersing apparatus is a hemispherical multiple-blade structure, birds cannot stop and branches cannot be built due to strong light diffusion regions on the blade surface and the smooth surface; according to the multiple-blade rotating structure, the light diffusion effect can be greatly improved, the birds are afraid to be close to the bird-dispersing apparatus by rotating the blades, and thus the bird-dispersing effect is greatly improved.
