Abstract

According to the gas-assisted ice body damage device and method in the submerged environment, non-contact ice melting and ice breaking are carried out in a gas-assisted mode, compared with a mechanical cutting method, equipment abrasion and noise are reduced, and the gas-assisted ice body damage device and method have the advantages of being simple in principle and operation, low in maintenance cost and the like; meanwhile, the high-energy beam adopted in the ice breaking device can be continuously transmitted in a gas channel to rapidly and effectively melt ice, operation is easy, the ice melting efficiency is high, the controllability of the ice breaking range is high, positioning is accurate, noise is low, and pollution and damage to the environment cannot be caused. And finally, compressed gas is released underwater to create a gas channel as a propagation path of various energy beams, so that energy loss caused by propagation of different forms of energy beams in water can be effectively avoided, and the purposes of melting and damaging the ice layer accurately, quickly and efficiently are achieved.
