The invention provides an ice breaking ship. Continuous method ice breaking devices are correspondingly arranged on the broadsides on the two sides of a ship body, an
impact method ice breaking deviceis arranged at the bottom of the ship body, according to the ice breaking ship, the continuous method ice breaking devices are provided, before the ice breaking ship is contacted with an ice layer, the action of a cone head structure on a hydraulic device is used for providing an instantaneous
impact force for the vertical cross section of the ice layer, multiple times of
impact can be achieved and used for breaking the inner part structure of the ice layer, crushability of the ice layer can be increased, and thus resistance is reduced in continuous ice breaking; and the action can also be used for breaking floating ice on the two sides of the ice breaking ship during sailing, thus lateral pressure on the ship body broadsides from the floating ice is reduced, and wear-out failure is reduced. According to the ice breaking ship, the impact method ice breaking device is provided, the ice breaking device extending out of the bottom of the ship and the
potential energy effect are used, theice breaking efficiency is increased, the gravity of the ship bottom can be used for being gathered at one point or a part, thus stress of the ice layer is increased, the ice breaking efficiency is increased, and meanwhile the ship body structure is not damaged.
