Problems solved by technology

The ship's pipeline is one of the weak links of the ship's impact resistance. Severe vibration will seriously affect the stealth performance of the ship, and will cause fatigue damage to the pipeline, which will cause fracture, seriously affect the normal navigation of the ship, and even cause an explosion.

Embodiment Construction

[0020] In order to further clarify the technical solution and working principle of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] A vibration-damping collar for a ship pipeline, comprising a peripheral frame 1, a vibration-damping mechanism, a mounting bracket 5, a pipe clamp member and the like.

[0022] Such as figure 1 , figure 2 In the shown embodiment, the pipeline is laid above the hull substrate, and the peripheral frame 1 is in the shape of "ㄇ" and fixed on the hull substrate. Parts such as pipelines, damping mechanisms, mounting brackets 5 and pipe clamping components are all arranged in the peripheral frame 1 .

[0023] The peripheral frame 1 is respectively provided with bases for installing guide rails 2 on the left and right sides of the top of the pipeline and the bottom of the pipeline, such as figure 1 As shown, the cross-section of the top base 3 ...

Abstract

The invention discloses a ship pipeline damping hoop. The ship pipeline damping hoop is provided with a damping mechanism, an installation support and a pipe clamp component; the damping mechanism comprises three damping modules installed on the left side and the right side and at the bottom of a pipeline, a triangular structure is formed by the three damping modules and connected with the pipeline through the pipe clamp component, and each damping module is provided with a front magnetic plane and a rear magnetic plane which are made of magnet materials; and like poles of each two magnetic planes are opposite, air cushions are arranged on the inner side faces of every two magnetic planes, and a viscous medium is arranged in a sealing space between every two air suctions, wherein each sealing space cannot be fully filled with the corresponding viscous medium. According to the ship pipeline damping hoop, vibrating energy can be absorbed, the condition that after the pipeline is impacted, vibrating deformation is generated is effectively restrained, and the stress amplitude value between the pipeline and a restraint device is reduced; damage to a pipeline joint is avoided, design is reasonable, and the structure is novel; the damping modules are easy to disassemble and assemble and replace, the installation position can be adjusted, and the ship pipeline damping hoop can be adaptable to pipe diameters with different sizes and a complex pipeline system; and the using mode is flexible.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a ship pipeline vibration damping collar. Background technique [0002] Ships are a type of ships that undertake special missions for the country. With the development of science and technology, the combat environment that ships need to adapt to is becoming more and more harsh, and the tests that they need to withstand are becoming more and more severe, such as underwater contact or non-contact explosive shocks, their own weapons, etc. The recoil impact caused by launching, etc. The ship's pipeline is one of the weak links of the ship's impact resistance. Severe vibration will seriously affect the stealth performance of the ship, and will cause fatigue damage to the pipeline, which will cause fracture, seriously affect the normal navigation of the ship, and even cause an explosion. Therefore, it is of great significance to study the shock resistance and vibration reduction ...
