Ice breaking ship breaking ice by collision method

Abstract

The invention provides an ice breaking ship breaking ice by a collision method. The ice breaking ship breaking the ice by the collision method includes a ship body, an ice breaking device is arrangedat the bottom of the ship body and includes round-table structures and a hydraulic device, wherein the hydraulic device is multi-stage, initial states of the round-table structures are embedded in theship body, the hydraulic device is connected to the upper ends of the round-table structures, the round -table structures are large at the upper ends and small at the lower ends, the interiors are empty, the lower ends are not closed, the four round-table structures are arranged, the round-table structure is arranged on each of two sides of a stern, and the round-table structure is arranged on each of two sides of a bow, and the stern and the bow are symmetrically provided with the round-table structures. According to the ice breaking ship breaking the ice by the collision method, the ice breaking device extending out of the bottom of a ship can be used for using the effect of potential energy, the ice breaking efficiency is accelerated, gravity at the bottom of the ship can also be usedfor concentrating on a point or a section of the ship body, thus the stress situation on an ice layer section is enlarged, and the ice breaking efficiency is improved. Meanwhile, a ship body structureis not damaged.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, in particular to an icebreaker for icebreaking by a collision method. Background technique [0002] In 1864, the Russians refitted a small ship "Pirot" into the world's first icebreaker to keep the route from Kronstadt to Oranienbaum open during the frozen period. The Russian-built "Yermak" icebreaker was the first icebreaker to sail in the Arctic. Since the 19th century, icebreakers have been continuously developed. Icebreakers are service ships used to break the ice on the water surface, open up waterways, ensure ships enter and exit ice-covered ports and anchorages, or guide ships to navigate in ice areas. Most European and American countries are located in extremely cold regions, and the rivers have been frozen for a long time, which is not conducive to the travel of ships. Therefore, these countries attach great importance to the development of icebreaker technology. On the other ha...

Problems solved by technology

However, the ice-breaking efficiency is not too high. When encountering an overly thick ice layer, one collision will not break the ice surface, and multiple collisions are required. Not only is the ice-breaking efficiency low, but the damage to the hull structure is also huge.
