Ice breaking cutter for icebreaker

Abstract

The invention discloses an ice breaking cutter for an icebreaker, and relates to the technical field of icebreakers. An outer hull plate installed at the bottom of the icebreaker comprises a bottom plate and two symmetrically arranged side plates, wherein the side plates, the bottom plate and the outer hull plate form a totally enclosed structure through full penetration welding; a continuous structure penetrating through the whole ship of the icebreaker is adopted, a sharp bow is arranged on the bow part, a stern adopts a structure transiting from gradual width to straight, and a frame plateis arranged at each rib position; and a plug welding panel for welding and fixing the side plates is arranged on one sides of the frame plates. According to the ice breaking cutter, finite element analysis is carried out, appropriate materials and excellent welding materials and welding processes are selected, so that the overall structural strength of the ice breaking cutter is improved, the icebreaking thickness is increased, the ice breaking efficiency is improved, a more economical channel is developed, and the rescue speed for trapped ships is improved.

Description

technical field

[0001] The invention relates to the technical field of icebreakers, in particular to an icebreaker blade for icebreakers. Background technique

[0002] Icebreakers are ships used to break the ice on the water surface, open up waterways, ensure ships enter and exit ice-covered ports, anchorages, or guide ships sailing in ice areas. They are divided into rivers, lakes, harbors or ocean icebreakers, usually located in polar regions. Harbors or seas in cold regions or high latitudes are often frozen, and navigation channels are blocked, and ice can damage and affect the operation of ships. Therefore, in order to ensure the smooth navigation of ice seas, icebreakers have become an indispensable tool. The so-called icebreaker The first principle is to use the weight of the hull itself to ballast the ice and then crush it; second, use the power of the ship itself to crush the ice through collision and extrusion, thereby digging the route. In the past, the collision...
