The invention discloses a
fender buffering structure of a polar icebreaker. The
fender buffering structure comprises a
fender buffering structure body composed of an outer-layer steel structure and an inner-layer elastic structure. The outer-layer steel structure comprises a fender top plate, fender side plates, fender front and rear end coamings, end limiting
cushion blocks, middle limiting
cushion blocks and inner limiting toggle plates, the fender top plate, the fender side plates, the fender front and rear end coamings and the
hull outer plate form a closed structure, the end limiting
cushion blocks are arranged at the two ends of each fender side plate, the middle limiting cushion blocks are arranged in the middles of the fender side plates, and the inner limiting toggle plates are arranged in the middle of the fender side plates. A plurality of internal limiting toggle plates are arranged between the fender side plate and the
hull outer plate, and the inner-layer elastic structure is limited through the end limiting cushion blocks, the middle limiting cushion blocks and the internal limiting toggle plates. The device is suitable for ship-ice and ship-ship collision scenes in a polar region complex environment, has a good buffering effect and can provide a good protection effect on a ship body; a fender buffer structure protection area is flexibly arranged according to ship design requirements and functions; and the low-
temperature resistance meets the long-term use requirements in a low-temperature environment.
