Ship drag reduction and auxiliary icebreaking bubble system

Abstract

The invention provides a ship drag reduction and auxiliary icebreaking bubble system, and relates to the technical field of polar region ship design and manufacture. The system comprises: a power supply control box respectively connected with a first air compressor and a second air compressor and used for supplying power to the first air compressor and the second air compressor and adjusting air flow of the first air compressor and the second air compressor in real time; an air storage device mounted at the front edge of the bottom of an icebreaker, wherein the air storage device is connectedwith the first air compressor through a first ventilation pipeline, and a one-way air injection plate is arranged at the bottom of the air storage device; a pressure stabilizing and flow dividing airtank, wherein the input end of the pressure stabilizing and flow dividing air tank is connected with the second air compressor; and a air injection assemblies installed on the bilge of the icebreaker,wherein each air injection assembly is connected with the output end of the pressure stabilizing and flow dividing air tank through a second ventilation pipeline. The system has the advantages of being small in occupied space in a ship, convenient to install, good in equipment adaptability and high in utilization rate. Ship drag reduction and auxiliary icebreaking can be achieved at the same time.

Description

technical field [0001] The invention relates to the technical field of polar ship design and manufacture, relates to an icebreaker sailing in all sea conditions, and in particular to a ship drag reduction and auxiliary icebreaking air bubble system. Background technique [0002] In the past 40 years, the coverage area and thickness of Arctic sea ice have continued to shrink, and polar navigation and resource development have become increasingly realistic. Huge economic benefits and important strategic significance have prompted the international ship market to demand professional icebreakers, various polar transport ships and engineering ships. The need is more and more urgent. For this reason, researchers are paying more and more attention to improving the ice-breaking capability and motion performance of polar ships in ice regions while reducing hull navigation resistance and fuel consumption. In addition to conventional structural strengthening and ice-breaking line optim...

Problems solved by technology

[0004] The existing air bubble drag reduction technology has not yet been applied to ships in ice regions, and the existing air bubble assisted icebreaking technology ignores the problem that it is difficult to function in open water areas or sea areas with less floating ice, and may even increase fuel consumption. , so inventing a bubble assist system with drag reduction in all sea conditions and auxiliary ice-breaking and ice-clearing performance is of great significance for improving the comprehensive capabilities of polar ships, especially for icebreakers in my country that need to go through a long clear water voyage to reach the north and south poles very innovative
