Technical Field

The invention relates to the technical field of ship engineering, in particular to a polar region icebreaker bow device.

Background

With social progress and increased resource demand, the development of the north pole called "last treasury of the earth" has gradually become an important item for the development of the world. The large-area icebound sea area in the polar region environment has serious influence on development and exploration. However, the conventional icebreaker has two ice breaking modes, one mode is that a water storage tank at the bow is filled with water to tilt the bow and move the own bow to the ice surface, and at the moment, the bow recovers the whole weight of the bow and crushes the ice by using the maximum weight. The single-time ice breaking area of the ice breaking mode is small, and the ship body is easy to damage.

The other is that the ice layer is directly split and crushed by the force of the propeller, the gravity of the ship body and the bow structure bulb, and the ice can be broken even under the thicker ice layer by repeated impact. Therefore, the research on the structure of the novel icebreaker is necessary.

The invention discloses an invention patent with the application number of CN 112478070A and the name of an ice breaking device applied to a ball nose head of a polar ship, and describes that an ice layer is gradually cut into smaller floating ice by adopting devices such as a main supporting arm, a secondary supporting arm, an ice breaking knife, an ice breaking blade and the like to realize the ice breaking effect. However, the ice breaking blade and the ice breaking blade of the device have small ice breaking contact area, the ice breaking effect is general, a thick ice layer cannot be cut, ice accumulation is easy to generate between the ice breaking blades, the ice load is increased, and the ice breaking efficiency is influenced.

In view of the above, the icebreaker is important for polar development and needs to be highly regarded. The ice breaking efficiency is extremely high by the self weight of the bow, but the requirement on the bow is high by impacting ice breaking, and the bulb is easy to damage. Therefore, how to improve the ice breaking efficiency of the ice breaker is a problem worth discussing.
