The invention discloses a self-adaptive rotary icebreaking device and method for an underwater vehicle, belongs to the technical field of underwater vehicle structure safety, and solves the problems that the rotary icebreaking device for the underwater vehicle is low in icebreaking efficiency and easy to damage a vehicle body. The device comprises a telescopic shell, a resonance mechanism and an ice skate blade mechanism. The whole resonance mechanism is integrated in the telescopic shell and can stretch out, draw back and rotate up and down. The resonance mechanism comprises a vibration exciter, a miniature laser detector and an ice breaking cone. The vibration exciter provides power for the ice breaking cone and can directionally change the excitation frequency of the ice breaking cone. The micro laser detector is used for detecting the thickness of an ice layer and assisting the vibration exciter to emit excitation frequency matched with the thickness of the ice layer; the ice breaking cone generates excitation frequency which is the same as or similar to that of an ice layer under the action of the vibration exciter; the resonance mechanism acts on an ice layer to be damaged, and the excitation frequency is adjusted according to different thicknesses of the ice layer, so that the purpose of resonance energy-gathering ice breaking is achieved. The method is suitable for assisting the icebreaking operation of the underwater vehicle.
