Shipborne underwater barrier breaking equipment and barrier breaking method

The invention relates to shipborne underwater barrier breaking equipment and a barrier breaking method, and belongs to the field of underwater barrier breaking, an emitting device emits an electrode to an underwater barrier, a capacitor discharging device is used for transmitting high voltage to the electrode after the electrode is emitted to the underwater barrier and discharging in liquid through the electrode, the high voltage electric energy breaks down a liquid medium, and the barrier breaking device is used for breaking the underwater barrier. High temperature and high pressure are generated in a short time along with a large amount of energy and shock waves, meanwhile, a large amount of charges remain on a hull, obstacles in the ship advancing process can be actively broken, and corona approaches aquatic organisms of the ship. Electric energy is converted into internal energy and mechanical energy through high-voltage electric pulses on the basis of the electro-hydraulic effect, underwater obstacle bre
