Split rotary rat-proof sphere

Abstract

The invention discloses a split rotary rat-proof sphere which comprises a fixed shaft sleeve, a rotary shaft sleeve, bearings and a sphere shell. 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.

Description

technical field [0001] The invention relates to a product for preventing and controlling harmful organisms, in particular to a split rotating rodent-proof ball for preventing and controlling rodent organisms. Background technique [0002] When ships, warships, etc. are docked at the dock, rodents may crawl into the hull through cables, and rodents in the hull can also invade the dock through cables. [0003] At present, the ships and ships of various countries in the world generally adopt the method of installing anti-rat baffles on the cables to prevent rodents from entering the hull, but structural design defects or operational problems of the anti-rat board often lead to poor sealing of the central hole during use, and low anti-rat performance . Contents of the invention [0004] The object of the present invention is to provide a split-rotating anti-rat ball, which can prevent rodents from climbing into the ship through cables, causing damage to the hull and the ship,...
