Abstract

The invention provides a pressure type air cushion icebreaker. The pressure type air cushion icebreaker comprises a hovership composed of a ship body, a flexible skirt arranged around the ship body, a cab and a work room arranged on the ship body, and a hovering unit arranged in the ship body, wherein the ship body is rectangular, and three sets of aero-propeller propellers of the same structure are installed on the ship body through rotary supports and located at three corners of the rectangular ship body respectively. High-pressure gas sprayed from the flexible skirt acts on water and ice, the ship body is supported by the flexible skirt under the backlash action, and this is equivalent to the fact that the gravity of the ship body acts on water and ice, so that ice is broken. An air cavity formed between ice and water by high-pressure gas makes an ice layer lose flexible support of water, so that the ice layer is broken more easily. The pressure type air cushion icebreaker can work alone or be pushed by a thrustor installed behind another ship to move as an air cushion ice breaking platform.

Description

technical field [0001] The present invention relates to an icebreaker. Specifically, an air cushion icebreaker. Background technique [0002] Icebreakers generally use two icebreaking methods. When the ice layer is not more than 1.5 meters thick, the "continuous" icebreaking method is often used. Mainly relying on the powerful power of the propeller and the bow to split and smash the ice, it can sail 9.2 kilometers per hour in the ice sea. If the ice is thicker, the "impact" icebreaking method is used. The bow of the icebreaker has a shallow draft and will easily rush to the ice, and the hull will crush the thick ice below into pieces. Then the icebreaker retreated a certain distance, and then rushed to the ice in front of it at full power, crushing the ice under the ship. Repeatedly, a new channel is opened. Icebreakers powered by fuel oil mostly use diesel engines to drive engines to generate electricity, and electric motors to drive propellers (combined unit drive). ...
