The fixed shaft sleeve and the rotary shaft sleeve are in the shapes of hollow ring columns, a pair of circumferential clamp plate grooves which are symmetric with each other around the axis of the fixed shaft sleeve is formed in two ends of the fixed shaft sleeve, and clamp plates are connected into the clamp plate grooves by adjusting bolts; the fixed shaft sleeve and the rotary shaft sleeve are provided with two symmetric half fixed shaft sleeves and two symmetric half rotary shaft sleeves, and the axial end surfaces of the two half fixed shaft sleeves and the two half rotary shaft sleeves are butted to one another, are connected with one another by mortises and tenons and are fixed by the aid of bolts; the rotary shaft sleeve is connected to the outer surface of the fixed shaft sleeve by the bearings arranged in bearing blocks at two ends of the rotary shaft sleeve; the sphere shell is a spherical shell, circular through holes are symmetrically formed in two ends of the sphere shell along the axis of the sphere shell, the sphere shell comprises two symmetrical half sphere shells and sleeves the outer surface of the rotary shaft sleeve, the through holes sleeve the outer surface of the fixed shaft sleeve in a movable fit manner, and the two ends of the sphere shell are connected onto two end surfaces of the bearing blocks by mounting screws. The split rotary rat-proof sphere has the advantage that the purpose of preventing rats from passing through places between wharves and ship hulls can be achieved by the aid of the split rotary rat-proof sphere.
