An anti-shock device for ship's tank-piercing pipeline

Abstract

The invention discloses an anti-impact device used for a cabin penetrating pipeline of a ship. The anti-impact device is characterized in that the segment, penetrating through the cabin wall, of the pipeline is sleeved with a connecting pipe; the connecting pipe is an assembly type cylindrical pipe with a large convex shoulder arranged at one end; the position which is located on the left side ofthe cabin wall and is close to the end with the large convex shoulder, of the connecting pipe is sleeved with an assembly type rigid connecting device, and the right side of the connecting pipe is sleeved with an assembly type anti-impact device; multiple first oil cylinders are evenly arranged between the large convex shoulder arranged on the connecting pipe and the cabin wall in the circumferential direction; and a cabin wall sleeve is fixedly mounted on the hole wall of the cabin wall in a penetrating manner, and assembly type outer barrels connected with the cabin wall are mounted on the left side and right side of the pipeline in a mirroring manner and a sleeving manner. The anti-impact device is reasonable and simple in structure, easy to manufacture, low in cost and convenient to use. Under the action of impact loads, the stress of the joint of the pipeline and the cabin wall can be reduced, deformation of the position, at the joint with the cabin wall, of the pipeline can be effectively reduced, and the risk that the joint of the pipeline and the cabin wall breaks under the impact action is avoided.

Description

technical field [0001] The invention belongs to the technical field of naval vessel pipelines, in particular to a novel impact-resistant pipeline penetration structure device. Background technique [0002] Ships will inevitably face impact problems during their service, which is directly related to the combat effectiveness and vitality of ships in war. With the development of modern military technology, the combat environment of ships is very harsh. The impact of high-performance bomb explosions on ships is increasing, making the ship's anti-shock capability an important technical indicator of combat capability. Even in peacetime, the collision shock caused by cruising may cause greater damage to the ship. [0003] There are many pipeline systems on the ship. After the ship is subjected to the impact of a close-range underwater explosion, although the hull structure is intact, many ship system equipment suffers functional damage, such as: pipeline threaded joints rupture, ...

AI Technical Summary

Problems solved by technology

The disadvantages of the impact resistance of these methods are: (1) The traditional enlarged pipe diameter can resist the effect of external load, but under the action of impact load, the variable diameter is easy to damage; (2) if the pipe is connected to the bulkhead The corrugated pipe is used at the place, which can only resist the impact along the length of the pipeline; (3) Polyurethane material is added to the connection between the pipeline and the bulkhead, which has a certain impact resistance, but it needs to resist more serious impact. If thicker elastic material is added, the flexibility of the pipeline will be too large; (4) After the spring is added, the flexibility of the pipeline will be too large when it does not resist the impact load
