Embodiment Construction

[0021] A kind of ice-breaking ice knife that this embodiment provides is used for ice-breaking ships, and the structure is as follows Figure 1-2 As shown, the hull plate 1 installed on the bottom of the icebreaker includes a bottom plate 3 and two symmetrically arranged side plates 2. The side plate 2, bottom plate 3 and the hull plate 1 form a fully enclosed structure through full penetration welding. The ice blade is a continuous box structure attached to the outside of the inner keel of the hull and arranged along the length of the ship. The bow and the center line have a single-sided 12° inclination. The arc transition within the range increases the width to 2m, and the arc transitions to a width of 0.8m within 4m and remains straight to the stern. In the 2m range at the end of the stern, it intersects with the center line at a single-sided 12° angle. Each rib position is provided with a frame plate 5 connecting one side of the side plate 2, and a plug welding panel 4 for...

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...
