An anti-fog and anti-icing ship deck with bionic multi-structure

Abstract

The invention discloses an anti-fog and anti-icing ship deck with a bionic multi-component structure, comprising a deck body and a micro-nano structure arranged on the upper surface of the deck body for anti-fog and anti-icing; the micro-nano structure consists of several trapezoidal The trapezoidal bump is composed of convex blocks, the side of the trapezoidal bump is provided with circular arc protrusions for repelling mist droplets, and the top surface of the trapezoidal protrusions is provided with granular protrusions for preventing mist droplets from spreading. In the present invention, the ship deck is arranged as an upper and lower two-layer rigid-flexible composite structure, and a micro-nano structure is arranged on the outer surface of the rigid layer, so that the small mist droplets around the deck are quickly merged into large mist droplets, and the small mist droplets stay on the deck. The surface probability shortens the time required for the bouncing process when large droplets hit the deck, and fully reduces the contact area between the droplets and the deck surface, thereby preventing the formation of fog / ice, which is beneficial to tankers, container ships, cruisers, destroyers, Deck formation / icing phenomena of various operational vessels such as offshore survey vessels and icebreakers have potential applications.

Description

technical field [0001] The invention belongs to a deck for marine ships, in particular to an anti-fog and anti-ice ship deck with a bionic multi-component structure. Background technique [0002] The polar marine environment is harsh, characterized by high humidity and low temperature. The icing formed under such climatic conditions has a significant impact on shipbuilding, shipping, scientific research, and military fields. In particular, the problem of ship navigation stability caused by deck icing has gradually become Focal points, moisture condensation and seawater splashing are the main factors responsible for the formation of icing on ship deck surfaces. [0003] At present, ship anti-icing methods mainly include mechanical ice breaking method, thermal ice melting method, chemical deicing method and so on. However, the mechanical ice-breaking method will cause damage to some precision equipment, and its efficiency is low, so it can only be used as a backup method; in ...

AI Technical Summary

Problems solved by technology

However, the mechanical ice-breaking method will cause damage to some precision equipment, and its efficiency is low, so it can only be used as a backup method; in addition to the huge energy consumption, the thermal ice-melting method also has the risk of secondary icing, and is generally only used for antennas, portholes, etc. The deicing of certain parts is not suitable for the deck of the ship; the cost of chemical deicing is high, the equipment is severely corroded, and it will also pollute the marine environment, especially the lower part of the main deck (in the ice accretion area) and the lattice structure The ship area below requires a more dedicated and stationary spraying mechanism

In summary, the existing anti-icing methods for ships have problems such as high energy consumption, low efficiency, environmental pollution, and time and space constraints, and cannot fundamentally effectively solve the complex formation / icing phenomenon faced by ship decks.
