Embodiment Construction
[0021] The present invention will be described in detail below by means of the accompanying drawings.
[0022] like figure 1 As shown, the progressive hole impact-resistant bulkhead of the ship provided by the present invention includes two parallel sandwich panels 1, and a progressive hole impact-resistant structure 2 is arranged between the two sandwich panels 1.
[0023] like figure 2 As shown, the gradual-hole impact-resistant structure 2 includes four identical progressive-hole structures uniformly distributed, and the gradual-hole structure includes a steel plate 2-1, and the steel plate 2-1 consists of the above Gradually increasing downwards, the plate steel 2-1 is provided with three circular openings 2-2 from top to bottom, the diameter of which increases from small to large, and the bottom of the plate steel 2-1 is connected with the small panel 2- 3 connections.
[0024] The plate steel 2-1 in each of the gradual hole structures is welded to the small panel 2-3...

The invention provides a gradually perforated impact resistant ship bulkhead. A gradually perforated impact resistant structure (2) is arranged between two sandwich plates (1), and the sandwich plates(1) comprise two parallel skin sheets, a sandwich plate (1-3) is arranged between the first skin sheet (1-1) and the second skin sheet (2-1), the first skin sheet (1-1), the second skin sheet (1-2) and the sandwich sheet (1-3) are filled with a filler (1-4), the gradually perforated impact resistant structure (2) comprises four uniformly distributed same tapered structures, each gradually perforated structure includes a steel plate (2-1), the steel plate (2-1) is gradually increased from the top to the bottom, and the steel plate (2-1) is provided with three circular openings (2-2) which arefrom top to bottom and whose diameter is changed from small to large. The lower part of the steel plate (2-1) is connected with the small panel (2-3). The gradually perforated impact resistant ship bulkhead has high strength and excellent vibration and noise reduction effect.
Description
technical field [0001] The invention belongs to the technical field of bulkhead protection devices for ships, and in particular relates to an anti-impact, anti-explosion and anti-noise progressive hole type anti-impact ship bulkhead. Background technique [0002] At present, the bulkheads of ships basically adopt multi-layer bulkhead structures, composite structures and sandwich plate structures to protect ships. The occurrence of various natural disasters or man-made disasters has severely tested the strength and toughness of ship bulkheads. Judging from the existing bulkheads of ships, explosion-proof facilities represented by explosion-proof walls are generally used for risk control. Mainly through the selection of steel plates with good impact resistance materials, there are few filled with buffer layers and fire-proof, insulating and noise-reducing materials. Although this method can effectively prevent the deformation and damage of the bulkhead caused by the explosio...
