Embodiment Construction

[0029] The invention discloses an ice-prying ice-breaking ship, which breaks the limitation of the traditional ice-breaking method, adopts the "bottom-up ice-prying type" ice-breaking, and provides a new idea and research direction for the design and ice-breaking method of a new type of ice-breaking ship. The design of the icebreaker includes a new icebreaker bow and a side structure with a large outer drift angle. The effect of deicing can be achieved. The icebreaker has two working modes after adopting a new bow and a new icebreaking method, which are divided into "continuous" and "repeated ice prying". The combination of the two methods makes the performance of the icebreaker better.

[0030] The innovative specific implementation of the present invention will be further described below in conjunction with the implementation examples and the accompanying drawings.

[0031] The "ice prying type" icebreaker provided by the invention has a structure such as Figure 1 to Figu...

Abstract

The invention discloses an ice-prying type icebreaker. The head portion of an icebreaker body is provided with an icebreaker bow (4) with taper type molded lines. The inside of the icebreaker bow is provided with intermediate frames and anti-ice crisscross structures which are connected with the icebreaker bow in a welded mode. The side of the icebreaker body is provided with a large flare angle structure. The buoyancy force of water to ice does not need to be overcome and an ice-breaking mode that the icebreaker has an auxiliary ice-breaking force from bottom to top is applied. According to the ice-prying type icebreaker, a mode that ice is broken from bottom to top is adopted, so that the buoyancy force of water to an ice layer does not need to be overcome, and labor is saved compared with an existing ice-breaking mode; the resistance of the ice to sailing is reduced; the ice-breaking efficiency is improved.

Description

technical field [0001] The invention relates to an icebreaker, in particular to an ice-prying type icebreaker. Background technique [0002] At present, the icebreaking methods of icebreakers mainly include continuous icebreaking and impact icebreaking. Continuous icebreaking is to use the pressure generated by the continuous upward and downward movement of the bow and the forward propulsion of the hull during the icebreaking process to break the ice. The broken ice depends entirely on the position along the waterline from the stem to the maximum ship width. If the ice layer is thicker and it is no longer possible to break the ice continuously, it is necessary to use the impact ice breaking method. The ice-breaking parts are mainly near the bow column and the bow section. After the bow hits the ice layer, a wedge-shaped crack is formed, and then the wedge-shaped ice block is broken under the punching pressure. [0003] The traditional top-down method of crushing ice has ce...
