An Embedded Bow Icebreaking Device Based on the Resonance Principle

Abstract

The invention relates to the field of mechanical technology, and provides an embedded bow ice-breaking device based on the principle of resonance, which is mainly composed of three parts: a resonance wheel, a power system and a position scheduling system. The resonance wheel is mainly composed of a hub, a ring gear and a shaft, which is used to drive the bow structure to vibrate at a specific frequency after the icebreaker climbs onto the ice layer; The device structure is used to provide power to the resonance wheel; the position adjustment system is composed of a pair of synchronous hydraulic cylinders, buckles and leaf springs, which are used to adjust the position of the resonance wheel and buffer the impact load of the ice layer on the resonance wheel. The remarkable advantage of the present invention is that the device can effectively improve the ice-breaking capacity without significantly increasing the displacement, effectively avoid being jammed by crushed ice, and can ensure the strength and wear resistance of the gear teeth, improving the mobility of the structure.

Description

Technical field: [0001] The invention relates to the field of mechanical technology, in particular to an embedded bow ice-breaking device based on the principle of resonance. Background technique: [0002] With the rise of Arctic resource development, the rich oil, natural gas and other resources in the polar regions will play an inestimable role in supporting the future development of the world economy. In recent years, the melting of ice in the Arctic waters has made it possible to open the Arctic shipping lanes, so it poses higher challenges to the icebreaking capabilities of icebreakers and other aspects. The existing icebreakers are mainly divided into three categories according to the working principle: one is to crush the ice layer by the forward power of the icebreaker; The raised bow of the ship is driven onto the ice, and the ballast water is pumped to the front cabin, where the weight of the water crushes the ice. The above three methods all have limitations in ...

AI Technical Summary

Problems solved by technology

The above three methods all have limitations in different aspects: the crushing method has high power requirements for the icebreaker, is only suitable for icebreaking operations on thinner ice layers, and is easy to be jammed by crushed ice; The strength requirements are high, and the impact of the strong vibration caused by the collision on the equipment and personnel on board cannot be ignored; the efficiency of the ballast method is low, the energy consumption is huge, and the large longitudinal tilt puts higher requirements on the normal operation of the equipment on board

Aiming at the above problems, a novel icebreaker bow and icebreaking method with the publication number CN104527919A utilizes the bow line shape inclined backwards, and an icebreaking blade is arranged above the bow, and the icebreaking blade exerts an icebreaking force on the thin ice layer, which can realize The thin ice layer is broken, but for the thick ice layer in the polar region, the ice-breaking blade wear rate of the invention is high, and the ice-breaking ability is poor
