Icebreaker

Abstract

The invention discloses an icebreaker which comprises a hull, a winch, an icebreaking device, a hull power device and a transmission connection device. The winch is located on the hull and connected with the icebreaking device through the transmission connection device, the icebreaking device comprises a transmission chain and a transmission device, the transmission chain is provided with a saw blade and high-frequency knocking hammers, the hull power device drive the winch so that the transmission connection device can run, the transmission connection device drives the transmission chain on the icebreaking device to act, and the transmission chain breaks ice of an ice surface through the saw blade and the high-frequency knocking hammers. An ice layer is destroyed through small force instead of being crushed through the gravity of the hull, impacts borne in the icebreaking process are effectively reduced, icebreaking efficiency is improved, the hull cannot be hugely damaged, meanwhile,the ice is broken freely and can be continuously broken, the icebreaking device is stored in the hull when icebreaking is not needed, use is convenient, and the one-time icebreaking area is large.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to 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 mainly include: b...

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 and 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 appears very heavy, and The speed of ice breaking is not fast, and it cannot even be realized in shallow sea areas. However, the icebreaker itself only ensures that it can travel, and it does not mean that other ships can travel.
