Description

Technical Field

[0001] The invention relates to the technical field of equipment installation and connection, and in particular to a bulkhead type hidden connection node. Background Art

[0002] The greatest wonder of the sea is naval battle, and warships are the main players in naval battles. Over the centuries, warships have gone through a development process from small to large, from wood to armor, and from primitive equipment to modern equipment.

[0003] Warships started with wooden structures and sailed by rowing. In the 15th century, sailing ships appeared. In 1814, the United States successfully developed a steam-powered warship without sails. 22 years later, the United States improved the steam ship from a water wheel to a screw propulsion. In 1834, wooden warships began to transform into ironclad ships. In modern times, due to the development of the oil processing industry and the promotion of war practice, the development of naval ships soared from the end of the 19th century to the First and Second World Wars. In the past 40 years, warships have developed at an astonishing speed in the direction of missileization, electrification, automation and nuclear power. The firepower of warships in most countries mainly uses missiles with various guided methods, which can attack surface ships 700 to 800 kilometers away and underwater submarines within 100 kilometers. Due to the application of electronic science and automatic control technology, ships have achieved three-dimensional coordination, early warning, rapid response, and preemptive strikes. They can cope with high-speed, multi-level, multi-directional, and multi-target attacks and launch counterattacks.

[0004] When it is necessary to erect structures or mount other equipment on a ship, the traditional method generally uses welding connecting ear plates or connectors on the bulkhead, which results in too many protrusions on the bulkhead, increases the radar wave reflection area, adversely affects the stealth performance of the ship, and affects the appearance of the ship. For some external structures or equipment that are not permanently installed or need to be temporarily fixed on the bulkhead, or for external columns or equipment that need to be repeatedly installed and removed, the disadvantages of the traditional method are particularly obvious, and the economy is poor, which not only affects the appearance of the bulkhead, but also makes installation and removal inconvenient, reducing labor efficiency. Summary of the invention
