Abstract

The invention discloses a protective liquid tank structure for resisting underwater explosion high-speed fragments, and belongs to the technical field of ship structure protection. The problem that an existing protective liquid tank is poor in protective performance is solved. The protective liquid tank is filled with absorption liquid and provided with a plurality of inner partition plates and a plurality of reinforcing ribs, the inner partition plates and the reinforcing ribs are arranged in the length direction of the ship, the inner partition plates are sequentially arranged from top to bottom, the reinforcing ribs and the inner partition plates are arranged in a staggered mode, and the two sides of each inner partition plate are fixedly connected with the liquid tank outer plate and the liquid tank inner plate respectively. And the two ends of each reinforcing rib are fixedly connected with the transverse bulkhead respectively. The multiple sets of reinforcing ribs and the inner partition plates are arranged in the length direction of the ship, the motion trails of detonation products and fragments can be changed, the detonation products and the fragments are made to deflect, meanwhile, shock waves generated when the fragments penetrate the liquid tank can be reflected, and therefore damage generated when the fragments penetrate the inner plate and the defense longitudinal wall of the liquid tank subsequently is reduced.

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 mission, the ship will be attacked by enemy underwater weapons such as torpedoes and depth charges, and its power core cabin and fuel tank will be hit by underwater weapons, which will pose a threat to its anti-sinkability. In the case of a contact explosion, a breach will be formed at the place where the ship is attacked by the explosion, and some cabins will be flooded. If the detonation power is too large, and the strength of the side protection structure cannot meet the protection requirements, a large number of cabins will be flooded, which will cause The ship sank. Various countries have always paid att...
