Problems solved by technology

[0003] The traditional metal hull is only coated with a layer of anti-corrosion paint on its outer surface, which mainly prevents the metal hull from being corroded by seawater and salt spray. However, the rigidity of the metal hull is relatively high. When it collides with other ships or docks, the metal hull Poor anti-collision performance

Embodiment 2

[0056] The manufacturing method based on the protective structure of embodiment one, its steps are as follows:

[0057] 1) Prefabricated through holes on the side wall of the ship;

[0058] 2) Fitting and welding the first pressure ring of the inner support ring to the side wall of the ship;

[0059] 3) Splicing and forming the inner support components, and fixing the two adjacent first support structures through the connection structure;

[0060]4) Press the inner support gland on the second pressure ring of the inner support ring, make the third connecting rod pass through the corresponding two second socket sleeves, and then pass through the through hole and insert into the outer protective structure;

[0061] 5) Make the end of the third connecting rod pass through the rubber backing plate, and make the rubber backing plate stick to the outside of the side wall of the ship;

[0062] 6) Fix the end plate threadedly connected to the third connecting rod;

[0063] 7) Lock ...

Abstract

The invention proposes a protective structure for a metal hull and a preparation method thereof, which includes through holes arranged in a matrix on the side wall of the ship, an inner support structure is arranged on the inner side of each through hole, and an inner supporting structure is arranged on the outer side of each through hole. There is an outer protective structure, and the inner support structure includes an inner support ring, an inner support gland and an inner support assembly; the inner support ring is welded and fixed on the inner side of the side wall of the ship, the inner support assembly is arranged in the inner support ring, and the inner support gland locks It is tightly fixed on the inner support ring; the invention improves the anti-collision performance of the ship body and ensures the safety performance of the ship.

Description

technical field [0001] The invention relates to a protective structure, in particular to a protective structure of a metal hull and a preparation method thereof. Background technique [0002] A ship is a man-made means of transportation that primarily operates in geographical waters. In addition, civilian ships are generally called ships, military ships are called ships, and small ships are called boats or boats, which are collectively called ships or boats. The interior mainly includes accommodation space, support structure and drainage structure, and has a propulsion system that utilizes external or self-contained energy. The appearance is generally a streamlined envelope that is conducive to overcoming fluid resistance. The materials are constantly updated with technological progress. In the early days, they were natural materials such as wood, bamboo, and hemp. In modern times, they are mostly metal, glass fiber, acrylic, and various composite materials. [0003] The t...
