Novel icebreaker structure

Abstract

The invention designs a novel icebreaker structure aiming at the defects of low work efficiency and high loss in the conventional icebreaker. The icebreaker structure comprises an icebreaker body with an icebreaking device, and is characterize in that the icebreaking device comprises a flexible steel frame which is fixedly arranged at the bottom of the icebreaker body and a driving device for controlling the stretching-over and contraction of the steel frame; a groove for accommodating the flexible steel frame and the driving device is formed at the bottom of the icebreaker body. According to the icebreaker structure, because a flexible steel frame structure is arranged on the contact surface of the icebreaker body and ice blocks, when the icebreaker leans against an ice surface, the steel frame is stretched over to reduce the contact area of the icebreaker body and the ice surface and increase the partial pressure of the icebreaker body applying to the ice surface, so that the ice surface is easy to break, the crashing times of the icebreaker body are reduced, the icebreaking efficiency is improved, and the loss of the icebreaker body is reduced.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, in particular to a novel icebreaking ship structure. Background technique [0002] In 1871, the German engineer Steinhausen designed and built the world's first icebreaker "Esse Brecher No. 1" at the Hamburg Shipyard. Since then, icebreakers have developed greatly, especially in European and American countries. Since most of the territory is located in the cold zone, many ports have a freezing period of up to half a year throughout the year. During this period, icebreakers are needed to maintain the smooth flow of ports and waterways. . Therefore, in these countries, the design and construction of icebreakers have always been attached great importance. Due to the continuous consumption of resources, the future will be an era of resource competition. With the progress of the times and the development of science, people have gradually discovered rich mineral resources on the seabed such as ...

AI Technical Summary

Problems solved by technology

At present, when an icebreaker encounters a relatively thick ice layer, it is difficult for most of them to break up the ice layer at one time. When repeatedly advancing, it not only makes the voyage time longer but also increases the damage to the ship structure, which leads to Increased probability of the hull being stuck in ice (Snow Dragon incident)
