Problems solved by technology

At present, most of the existing polar transport ships are ice-strengthened transport ships with bulbous bows. This type of ship has excellent open water performance, but does not have ice-breaking capabilities. It can only sail in the Northeast Passage under the pilotage conditions of icebreakers; or has An ice-breaking polar transport ship with an ice-breaking slanted bow. This type of ship has excellent ice-breaking performance, but poor open-water performance

Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] see figure 1 , the present invention provides a technical solution: a novel icebreaker bow structure, the bow structure includes a bow upper part 1, a bow middle part 2 and a bow lower part 3, and the bow upper part 1 is a straight bow, perpendicular to The horizontal plane, that is, the inclination angle is 90°. This straight bow form is beneficial to the layout of the deck and the layout of the chain locker, as well as construction; the middle part of...

Abstract

The invention discloses a novel icebreaker bow structure and an ice breaking method. The bow structure comprises a bow upper part, a bow middle part and a bow lower part, the bow upper part is a straight bow body and is perpendicular to a horizontal plane, and the inclination angle is 90 degrees; the bow middle part adopts an ice-breaking blade inclining downwards, and the inclination angle of theice-breaking blade is 15-40 degrees; the bow lower part adopts a bulbous bow, the lower edge line of the bulbous bow is provided with an ice-breaking blade, and the inclination angle of the ice-breaking blade is 35-50 degrees; the upper edge line of the bulbous bow is provided with an ice-breaking blade with the inclination angle of 15-30 degrees. The bow structure can have good ice breaking performance under ice conditions at different degrees in polar regions and have good resistance performance in open water areas at the same time.

Description

technical field [0001] The invention relates to the technical field of polar ships, in particular to a novel icebreaker bow structure and an icebreaking method. Background technique [0002] The polar region is a strategic space that all countries in the world must compete for in the future. At present, international polar affairs are undergoing profound changes. The Arctic region has entered the preparation period for development and utilization. The Antarctic region is undercurrents of competition surrounding resource development. International competition for major scientific frontier research such as climate change, environmental evolution, the universe and the origin of life significantly intensified. [0003] There are many potential resources in the polar regions. For example, Antarctic glaciers contain a wealth of climate information, which is a very good sample for studying climate change; Antarctic krill is one of the organisms with the highest protein content on...
