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

Abstract

The invention relates to the technical field of ships, in particular to an externally-hung-type shape-preserving mine-preventing cabin. The externally-hung-type shape-preserving mine-preventing cabincomprises two parts of a main body and an auxiliary body, the main body comprises empty cabins which are arranged on a resistance-reducing liquid cabin and a function cabin chamber, resistance-reducing liquid is loaded in the resistance-reducing liquid cabin, and the resistance-reducing liquid cabin is connected with a discharging pump; the function cabin chamber is internally provided with a power source module and a control system, and the control system controls work of the discharging pump; and one face of the auxiliary body is fixed to the main body, and the other face of the auxiliary body is fixed to a ship body. According to the externally-hung-type shape-preserving mine-preventing cabin, through the deformation energy-absorbing principle, underwater exploding impact force acting on the ship body is effectively absorbed; through the shape-preserving design, change of the original gravity center, floating center and metacenter of a conveying ship is reduced, and the influence ofrefitting on the ship sailing performance is reduced; the ship overall streamline is optimized, and the resistance increment caused by the externally-hung cabin is decreased; and the resistance-reducing liquid for reducing viscous resistance is loaded in the mine-preventing cabin and discharged in the sailing process and wraps the surface of the ship body to reduce the resistance of the ship bodyand increase the sailing 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
