ENERGY-ABSORBING PROTECTIVE STRUCTURE OF CERAMIC HOLLOW FLOATING BALL AND PREPARATION METHOD THEREFOR

Disclosed are an energy-absorbing protective structure of a ceramic hollow floating ball (1) and preparation method therefor. The energy-absorbing protective structure comprises spherical shells (2, 3) manufactured using a polyethylene material having an ultrahigh molecular weight. The spherical shells (2, 3) are provided on the surface of the ceramic hollow floating ball (1). The energy-absorbing protective structure manufactured using a polyethylene material having an ultrahigh molecular weight can prevent the ceramic hollow floating ball (1) from being damaged due to impacts during transportation and mounting, can effectively absorb large energy released by the ceramic hollow floating ball (1) during the occurrence of deep-sea implosion to prevent effects on other structures of a submersible and ensure the safety of the crew in a manned submersible, and is simple in the overall structure and easy-to-manufacture. La présente invention concerne une structure de protection absorbant l'énergie d'une bille flot
