Intelligent shock absorber of pipeline

Abstract

The invention aims to provide an intelligent shock absorber of a pipeline. The intelligent shock absorber comprises a pipe clamp, a bracket, a central frame structure and a low-layer rubber shock absorber. The pipe clamp is a circular structure comprising two semi-circular pipe clamps, the pipeline passes through the interior of the annular structure, a rubber clamping ring is mounted between the annular structure and the pipeline, the pipe clamp is fixed on the bracket, the bracket is fixed on the central frame structure, the low-layer rubber shock absorber is mounted between the central frame structure and a base structure, a power amplification module is arranged in the central frame structure, inertia type electromagnetic actuation modules which are connected with the power amplification module are arranged respectively on two sides of the power amplification module, and an acceleration sensor is arranged on the top plate of the central frame structure and connected with the power amplification module. The intelligent shock absorber is mainly aimed to isolate the pipeline system shocks which are ubiquitous on ships, and is capable of effectively controlling the transfer of broadband shocks from a pipeline system to a ship structure.

Description

technical field [0001] The invention relates to a damping device, in particular to a pipeline damping device. Background technique [0002] Piping systems have very important applications in various industrial fields, especially in the shipbuilding industry. Piping systems (such as domestic water pipelines and cooling water pipelines) commonly exist on various ships and play an important role. effect. However, the vibration and noise of the pipeline has not been well controlled. Strong pipeline vibration will not only loosen the pipeline accessories, especially the connecting parts of the pipeline, but also radiate noise into the cabin. Internal and underwater radiated noise. At present, the vibration control of the pipeline system is still dominated by passive control technology, such as the use of vibration isolation (such as pipe clamps or elastic horse support), dynamic vibration absorbers and laying damping materials on the surface of the pipeline, etc. [0003] The ...

Problems solved by technology

However, this passive vibration isolation structure can only effectively isolate medium and high-frequency vibrations, and cannot achieve ideal control effects on low-frequency vibrations of pipelines, and cannot adapt to changes in pipeline vibration frequency caused by changes in pump operating conditions.
