Problems solved by technology

However, the liquid tank converts the "point load" of fragments into complex "surface loads" such as shock waves, hysteresis flow, and bubble collapse shock waves in the liquid tank, and the kinetic energy of the fragments is transferred to the liquid tank, which may easily cause the overall damage of the liquid tank
In addition, when the high-speed fra...

Embodiment Construction

[0019] The present invention will be further described below in conjunction with specific examples and accompanying drawings.

[0020] The invention provides a battleship protective liquid tank based on decompression and subdivision functions, such as figure 1 As shown, the cabin body 2 surrounded by the tank front panel 1, the tank rear panel 3, and the tank side panels is composed of a tubular sub-cabin structure 2.1 with a regular hexagonal cross-section. The adjacent subdivision structures 2.1 are tightly connected so that the section is honeycomb-shaped, and the side walls of the subdivision structures 2.1 are perpendicular to the side panels of the tank, and are densely paved in the entire cabin body 2; every six circumferentially connected subdivision structures 2.1 are provided with A liquid-free empty cabin 2.3 The empty cabin plays the role of pressure relief and expansion reduction, which can immerse the expanded liquid after being hit by high-speed fragments, relie...

Abstract

The invention provides a battleship protective tank based on pressure relief and subdivision functions, including a tank body surrounded by a tank front plate, a tank rear plate and a tank side plate,wherein the tank body is provided with a tubular subdivision structure with a regular hexagonal section, the adjacent subdivision structure is closely connected so that the section is honeycomb, andthe side wall surface of the subdivision structure is perpendicular to the tank side plate and closely spread over the whole tank body; an empty tank with no liquid is arranged in the middle of everysix circumferentially connected subdivision structures; Other subdivision structures are filled with liquids, that is, liquid subdivision. The invention adopts the honeycomb type subdivision structure, which can absorb more energy generated by explosion while reducing the relative mass, enhance the structural strength, enhance the protective capacity of the liquid tank and protect the important compartment of the warship from being destroyed. Each subdivision structure is independent of each other and can be protected against second or even multiple strikes. Empty cabin plays the role of pressure relief and expansion reduction, which can make the liquid swollen after being hit by high-speed fragments immersed, alleviate the expansion of liquid damage, and protect other cabins.

Description

technical field [0001] The invention belongs to a side protection structure of a battleship, and in particular relates to a protection liquid tank of a battleship based on the functions of pressure relief and subdivision. Background technique [0002] With the rapid development of anti-ship missile technology, ships are facing more and more serious explosion threats in 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's protection system mainly consists of deck protection, ship bottom protection, side protection and special protection. Among them, the side protection has the largest area and the highest protection requirements. The side is the weak part of the ship. The added anti-knock protection structure can prevent t...
