Multi-layer anti-blast protection structure on ship side

Abstract

The invention discloses a warship board multilayer anti-detonation protection structure. The warship board multilayer anti-detonation protection structure comprises a double-layer shell, a void compartment, a first liquid compartment and a second liquid compartment, wherein the double-layer shell, the void compartment, the first liquid compartment and the second liquid compartment are sequentially ranked from the outer side of a warship body to the inner side of the warship body, the water filling height h of the first liquid compartment and the water filling height h of the second liquid compartment are 70%-80% of a compartment height H, the void compartment is separated from the first liquid compartment through a first compartment separation plate, the first liquid compartment is separated from the second liquid compartment through a second compartment separation plate, the second liquid compartment is separated from an inner compartment of a warship through a third compartment separation plate, and the side, towards a compartment body, of the second liquid compartment is fixedly connected with a plurality of longitudinal box girders which are vertically ranked at intervals. The warship board multilayer anti-detonation protection structure with the structural style has the advantages of being light in weight, good in anti-detonation performance, high in residual intensity and the like, when a warship board is impacted by detonation, most detonation impact energy can be absorbed, the compartments of the warship are prevented from being damaged, and personal losses are avoided.

Description

technical field [0001] The invention relates to a ship hull structure, in particular to a ship hull side structure, which belongs to the technical field of ship engineering. Background technique [0002] With the rapid development of anti-ship missile technology, ships are facing more and more severe explosion threats during combat. The shock wave and high-speed fragments generated by the explosion of the anti-ship missile warhead caused varying degrees of damage to the ship's hull structure, shipboard equipment and personnel, thereby destroying the ship's ability to perform tasks normally and even causing it to sink. The ship protection system mainly consists of deck protection, side protection, bottom protection and special protection. Among them, the side protection has the largest area and the highest protection requirements. The side is the weakest part of the ship. The added anti-knock protection structure can protect the internal important equipment, ammunition and f...

AI Technical Summary

Problems solved by technology

[0003] A protective structure must be installed on the side of a ship to effectively resist the attack of anti-ship missiles. At present, the protective structure of the side of a ship is realized by increasing the depth and thickness of the steel plate, which greatly increases the weight of the ship's hull structure, seriously Affects the maneuverability of the ship
