Icebreaker

Abstract

The invention relates to an icebreaker which comprises an icebreaker body and further comprises an icebreaking device and an auxiliary icebreaking device which are arranged on the icebreaker body. Theicebreaking device comprises a roller icebreaking device which is mounted at the front end of the stem of the icebreaker and a power mechanism which is mounted inside the stem of the icebreaker and suitable for supplying power to the roller icebreaking device; the roller icebreaking device comprises a primary roller assembly arranged in the middle of the front end of the stem of the icebreaker and secondary roller assemblies arranged on the left side and the right side of the primary roller assembly; the primary roller assembly comprises a main mechanical arm connected with the power mechanism, a main mounting guide rail rotatably connected to the front end of the main mechanical arm and a pair of main rollers arranged on the main mounting guide rail; the auxiliary icebreaking device is mounted above the roller icebreaking device and comprises a supporting rod mounted at the upper end of the main mechanical arm and a microwave heater arranged at the front end of the supporting rod; and the supporting rod is arranged in parallel with the ice surface and stretches out of the main rollers forwards, and the microwave heater is located above the ice surface and does not make contact with the ice surface.

Description

technical field [0001] The invention relates to the technical field of ice breaking, in particular to an ice breaking ship. Background technique [0002] At present, icebreakers generally have two methods of continuous icebreaking and impact icebreaking for icebreaking operations. When the ice layer does not exceed the designed ice-breaking thickness of the ship, the continuous ice-breaking method is generally adopted. If the ice layer is thicker than the maximum icebreaking thickness designed by the icebreaker, or in more complex ice accumulations, thick ice areas, and more difficult ice ridge areas, the impact icebreaking method is required. [0003] Both of the above two ice-breaking methods have certain problems: the continuous ice-breaking method is slow to break ice, and can only be used in sea areas with low ice strength and thin thickness, and has high requirements on the strength of the ship itself; the impact ice-breaking method has low ice-breaking efficiency and...

Problems solved by technology

[0003] Both of the above two ice-breaking methods have certain problems: the continuous ice-breaking method is slow to break ice, and can only be used in sea areas with low ice strength and thin thickness, and has high requirements on the strength of the ship itself; the impact ice-breaking method has low ice-breaking efficiency and energy consumption Larger, the biggest problem is that the hull is prone to getting stuck in ice

At the same time, these methods all put forward higher requirements on the hull structure, propulsion devices and auxiliary facilities, etc., and even cannot be realized in shallow sea areas.
