AI Technical Summary
Technical Problem
When ships are trapped in thick ice, traditional icebreaking methods are inefficient, dangerous, and cause serious damage to the hull, making it impossible to effectively create a way out of the predicament.
Method used
The hoisting operation platform integrates a jet-resonance module, which pre-damages the ice layer with high-pressure water jets, and combines it with a resonance ice-breaking module to make the ice layer resonate using a vibration generating unit, forming effective cracks to accelerate ice breaking.
Benefits of technology
It achieved efficient, safe, and rapid icebreaking, shortened the time to escape from distress, reduced energy consumption and damage to the hull, avoided the risk of explosion, and provided a safe and reliable escape route.

Abstract
This invention proposes an icebreaking device, vessel, and method combining jet-resonance technology for ice-trapped vessels, relating to the field of polar icebreaking technology. It addresses the problem of conventionally powered vessels or icebreakers with low ice levels struggling to break through ice in areas with ice thickness greater than 1.2 meters. It includes a hoisting platform, a jet icebreaking module, a resonant icebreaking module, and an attachment stabilization module. The hoisting platform is used for assembly with an external crane. The jet icebreaking module outputs water jets to break the ice. The resonant icebreaking module induces resonance in the ice layer. The attachment stabilization module includes a helical anchor bolt and a power mechanism. The power mechanism drives the helical anchor bolt to rotate relative to the hoisting platform, and the helical anchor bolt drills into the ice surface to fix the hoisting platform. It is primarily used on polar vessels to break through ice and escape when a vessel is trapped.
