Surface-piercing type mobile pulsation load air cushion icebreaker

Abstract

The invention discloses a surface-piercing type mobile pulsation load air cushion icebreaker. A hull system mainly consists of a main hull, an air cushion, an ice cutter, a cab and a guardrail; a propulsion system is composed of air-screw propellers which are distributed at the tail and the bottom of the main hull and generate the sinusoidal pulsation load on sea ice in the vertical direction while enabling the air cushion icebreaker to advance at the constant speed; an arranged monitoring system mainly comprises a sensor array and a camera array, is also arranged on the periphery of the mainhull and is used for collecting water level and ice condition information; and an arranged control system is used for analyzing and processing the information collected by the monitoring system, and controlling the propulsion system according to the collected information so as to adjust the advance speed and the pulsation frequency of the vertical pulsation load. The air cushion icebreaker has theadvantages that the structure is simple, meanwhile, the ice layer waveform resonance is matched with the vertical ice cutter arranged at the bottom of the main hull, and thus the ice breaking efficiency is high.

Description

technical field [0001] The invention belongs to ship engineering technology, and in particular relates to a cut-and-dash mobile pulsating-load air-cushion icebreaker. Background technique [0002] The Arctic waterway is the shortest route connecting the three continents of Asia, Europe, and the United States. Compared with traditional routes, it can greatly shorten the voyage of transport ships and reduce transportation costs. In recent years, with global warming, the thickness and coverage of polar sea ice has gradually decreased. Many merchant ships have shuttled through the Northeast Passage under the guidance of icebreakers. For conventional icebreakers, according to different icebreaking methods, it can generally be divided into continuous icebreaking and impact icebreaking. The former is mainly applicable to ice conditions where the thickness of the ice layer does not exceed 1.5 meters, and the bow contacts the surface of the ice layer to cause extrusion damage. The ...

Problems solved by technology

[0004] However, both the waveform resonance ice-breaking method and the pressure-type bending ice-breaking method have certain limitations. The former is difficult to apply to harsh ice conditions, and the latter relies solely on its own gravity to break ice, which consumes a lot of energy and has low ice-breaking efficiency.
