an ice-breaking submersible

Abstract

The invention provides a hob type icebreaking submerged body and belongs to the field of icebreaker design and manufacture. The icebreaking submerged body is mainly characterized in that the designedsubmerged body can freely float and submerge below an ice layer through a buoyancy adjustment method, and when the submerged body floats to the ice layer and makes contact with the ice layer, the submerged body hobs the ice layer through a large hob machine installed on the upper portion of the submerged body so as to break the whole structure of the ice layer; a mechanical frame is located between a reamer and a buoyancy adjusting body and connects the reamer with the buoyancy adjusting body; and when buoyancy adjusting the submerged body is increased continuously, the ice layer can be impacted through the buoyancy, and therefore the ice layer is broken. The method of breaking ice from bottom to top can break thick ice of a large area within a short time, and under the condition that multiple propellers are additionally arranged, the icebreaking submerged body can freely break the ice under the ice layer. The icebreaking submerged body is suitable for opening a channel for a ship in the thick ice area and has the beneficial effects of being good in maneuvering characteristic, high in icebreaking operating speed, high in efficiency, high in practical value and the like.

Description

technical field [0001] The invention belongs to the technical field of icebreakers, and in particular relates to a novel icebreaking submersible and an icebreaking method thereof. Background technique [0002] Icebreakers are mainly used to break through the ice and open up channels to ensure that ships can sail in ice-covered ports or navigation areas. General icebreakers can be divided into lakes, rivers, harbors and ocean icebreakers according to their navigation areas. The hull structure of an icebreaker is very different from that of a general ship. The hull shape, bow, propulsion device and propeller are the main areas of difference. In terms of ship shape, the ship shape of the icebreaker is relatively wide horizontally and relatively short vertically. Steel plates and dense skeletons are used for reinforcement. In order to effectively reduce the stress and strain on the hull due to the bow riding on the ice, in the initial stage of design, it is necessary to consi...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned ice-breaking method has high requirements on the structure of the ice-breaking ship, and special strengthening treatment is required for the hull. The outer shell of the ship is a non-removable and repairable structure. In addition, the cost of icebreakers is high and the research and development period is long; the icebreaking speed of surface icebreakers is limited.
