A continuous icebreaker

Abstract

The invention provides an icebreaker for continuous icebreaking, which includes a hull, and an icebreaking device is provided on both side sides of the hull. Cone head type structure, the first section of mechanical support is arranged on the side of the hull, the second section of mechanical support and the first end mechanical support are connected through a shaft-connected rotator, and the cone head structure is connected to the second section of mechanical support. The continuous ice breaking icebreaker provided by the present invention, before the icebreaker comes into contact with the ice layer, uses a cone head type structure, and under the action of a hydraulic device, it can give an instantaneous impact force to the vertical section of the ice layer, which can be hit multiple times, and is used to destroy the ice layer. The internal structure increases the breakability of the ice layer, thereby reducing the resistance encountered during continuous ice breaking. It can also be used to destroy the ice floes on both sides of the icebreaker during navigation, reduce the lateral pressure of the ice floes on the side of the hull, and reduce wear and tear.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, in particular to an icebreaker for continuous icebreaking. 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 hand, with th...

Problems solved by technology

[0004] When the ice layer does not exceed 1.5 meters, the "continuous method" ice-breaking method is adopted, mainly relying on the power of the propeller and the bow to split and smash the ice layer, and can sail 9.2 kilometers per hour in the ice sea. Multiple collisions, not only the ice-breaking efficiency is low, but also the damage to the hull structure is huge
