Abstract

The invention discloses a protective liquid tank structure against high-speed fragments of underwater explosion, belonging to the technical field of ship structure protection. The invention solves the problem of poor protective performance of the existing protective liquid tank. The protective liquid tank is filled with absorbing liquid, and is arranged with a number of inner partitions and a number of reinforcing ribs. The inner partitions and each reinforcement are arranged along the length of the ship, and the inner partitions are arranged in sequence from top to bottom. Several inner partitions are arranged in a staggered manner, the two sides of each inner partition are respectively fixed to the tank outer plate and the tank inner plate, and the two ends of each stiffener are respectively fixed to the transverse bulkhead. Setting up multiple sets of stiffeners and inner baffles along the length of the ship can not only change the trajectory of the detonation products and fragments to deflect them, but also reflect the shock waves generated when the fragments penetrate the tank, thereby reducing fragmentation. The damage caused by the subsequent penetration of the tank inner plate and the defensive longitudinal wall.

Description

technical field [0001] The invention relates to a protective liquid tank structure against underwater explosion high-speed fragments, belonging to the technical field of ship structure protection. Background technique [0002] With the development of science and technology, large surface ships play an increasingly irreplaceable role in modern naval warfare. During the ship's mission, it will be attacked by enemy underwater weapons such as torpedoes and depth charges, and its power core compartment and fuel tank will be hit by underwater weapons, which will pose a threat to its sinking resistance. In the event of a contact explosion, a breach will be formed at the place where the ship is attacked by the explosion, and some cabins will enter water. If the detonation power is too large and the strength of the side protective structure cannot meet the protection requirements, a large number of cabins will enter the water, which will cause The ship sank. Various countries have ...
