Externally-hung-type shape-preserving mine-preventing cabin

Abstract

The invention relates to the technical field of ships, in particular to an externally mounted shape-conserving lightning protection cabin. An external shape-conserving lightning protection cabin includes two parts: a main body and an appendage. The main body includes an empty cabin, which is arranged in a drag-reducing liquid tank and a functional cabin. The drag-reducing liquid tank is loaded with drag-reducing liquid. There is a discharge pump; the functional compartment is equipped with a power supply module and a control system, and the control system controls the work of the discharge pump; one side of the appendage is fixed on the main body, and the other side is fixed on the hull. The lightning protection cabin of the present invention utilizes the principle of deformation and energy absorption to effectively absorb the impact force of the underwater explosion acting on the hull; it adopts a shape-conserving design to reduce the changes in the original center of gravity, buoyancy, and steady center of the transport ship, and reduce the damage caused by refitting. The influence of nautical performance; optimize the overall streamline shape of the ship, reduce the resistance increase caused by the external cabin; the lightning protection cabin is filled with drag-reducing liquid that reduces viscous resistance, which is discharged during navigation, wraps the hull surface, reduces hull resistance, and increases speed.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to an externally mounted shape-conserving lightning protection cabin. Background technique [0002] With the increasing demand for logistics transportation in modern warfare, civilian transport ships are playing an increasingly important role in logistics transportation in modern warfare, so their living environment is also facing more and more serious threats, often attacked by torpedoes, mines , depth charges and other weapons threats. In the face of these threats, how to effectively enhance the protective capabilities of transport ships and ensure that they can maintain effective vitality under the attack of various weapons has become the top priority of the research of various military powers. Among the various ways and methods to enhance the protective ability of transport ships, the protective effect of the side structure is undoubtedly the most effective one. The purpose of s...

AI Technical Summary

Problems solved by technology

At present, the lightning protection structure of military ships has been arranged inside the side structure during construction. For civil transport ships, if a protective structure is added on the basis of the original hull, the construction will be troublesome and the modification will be more difficult; The original space in the cabin was occupied, destroying its overall layout, and it needed to be dismantled and restored after the war; third, the weight of the hull structure increased, and the positions of the center of gravity and buoyancy changed, and the navigation performance of the transport ship was affected
