Embodiment Construction

[0018] The present invention will be further described below in conjunction with specific examples and accompanying drawings.

[0019] The present invention provides a kind of interlayer defensive vertical wall, such as Figure 2 to Figure 4 As shown, it includes a sandwich panel composed of two rigid panels 15 and a Kevlar core board 14 in the middle, the sandwich panel is connected with a fixed plate 13 around, the upper part of the fixed plate 13 is connected with the ship deck 11, and the fixed plate 13 The bottom is connected with the bottom plate 12, and the two ends of the fixed plate 13 are connected with the bulkhead.

[0020] The thickness of the fixed plate 13 is the same as the total thickness of the sandwich plate, and the fixed plate 13 is provided with a groove, and the Kevlar core plate 14 extends into the groove; the panel 15 and the fixed plate 13 Fixed by butt welding.

[0021] In order to ensure the strength of the weld, a reinforcing plate 16 is connecte...

Abstract

The invention provides an interlayer longitudinal defending wall comprising an interlayer plate composed of two rigid panels and a Kevlar core plate at the middle, wherein fixing plates are connected with the periphery of the interlayer plate, the upper parts of the fixing plates are connected with a deck of a ship, the lower parts of the fixing plates are connected with a base plate of the ship, and two ends of each of the fixing plates are connected with cabin walls. The wall provided by the invention adopts an interlayer plate structure, and utilizes the characteristics of Kevlar, such as light weight and high strength and flexibility, so that the weight of the wall is reduced while the anti-penetration performance of the longitudinal defending wall is improved.

Description

technical field [0001] The invention belongs to the field of ship structures, and in particular relates to a longitudinal wall for interlayer defense. Background technique [0002] Ships must not only have strong combat capabilities, but also have corresponding survivability, especially the survivability under the conditions of being attacked by the enemy. In combat, large surface ships are vulnerable to attacks by weapons such as anti-ship missiles with a certain ballistic terminal velocity and carrying high explosives. These anti-ship weapons can penetrate the side shell and enter the internal explosion and produce a strong explosion shock wave and a large number of high-speed fragments, causing damage to structures, personnel and equipment. In order to effectively resist the attack of anti-ship weapons and ensure that the degree of damage or damage to the ship under the condition of anti-ship weapon attack is controlled within the allowable range, so as to improve the su...
