Icebreaker structure

Abstract

The invention discloses an icebreaker structure. The structure comprises a hull and an ice breaking device, a windlass and a hull power device are arranged on the hull, the windlass is connected withthe hull power device, the windlass is connected with the ice breaking device through a transmission connecting device, the ice breaking device comprises a supporting body and a transmission chain, the transmission chain comprises a transmission chain type hammer and saw bits, the windlass is driven to operate by the hull power device, the windlass allows the ice breaking device to be lifted, lowered or moved through the transmission connecting device, and ice breaking operation is conducted by the transmission chain type hammer and the saw bits under the action of the transmission connectingdevice. According to the structure, the ice breaking device is utilized to break icy layers, the icy layers are not crushed and broken by the gravitational force of the hull, the subjected impact andcollision in the ice breaking process are effectively reduced, severe damage on the hull is not generated, ice breaking is convenient, the ice breaking device is accommodated in the hull body when icebreaking is not needed, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a structure of an icebreaker. Background technique [0002] Icebreakers are ships used to break the ice on the water surface, open up waterways, ensure ships enter and exit ice-covered ports, anchorages, or guide ships sailing in ice areas. They are divided into rivers, lakes, harbors or ocean icebreakers, usually located in polar regions. Harbors or seas in cold regions or high latitudes are often frozen, and navigation channels are blocked, and ice can damage and affect the operation of ships. Therefore, in order to ensure the smooth navigation of ice seas, icebreakers have become an indispensable tool. The so-called icebreaker The first principle is to use the weight of the hull itself to ballast the ice and then crush it; second, use the power of the ship itself to crush the ice through collision and extrusion, thereby digging the route. Existing ice-breaking methods ma...

AI Technical Summary

Problems solved by technology

These methods all put forward higher requirements to the hull structure, propulsion device and its auxiliary facilities, etc., the impact collision received in the ice breaking process, the hull vibration is very large, in order to withstand strong impact, the structure of the hull also shows very heavy, and The ice-breaking speed is not fast, and it cannot even be realized in shallow sea areas. The ice-breaking operation takes a long time, the ice-breaking operation is slow, and the ice-breaking area is small at a time.
