Abstract

The invention relates to the technical field of vibration sensors, in particular to a self-powered sensing device for monitoring vibration of an ocean structure. The device comprises a connecting plate, a spring, an impact plate, a friction nano power generation unit and a shell, the connecting plate, the spring, the impact plate and the friction nano power generation unit are all arranged in theshell. One side of the connecting plate is connected with one side of the inner side of the shell; one end of the spring is connected with the other side of the connecting plate, the other end of thespring is connected with the impact plate, the friction nano power generation unit is connected with one side of the inner side of the shell, and the connecting plate and the friction nanometer powergeneration unit are oppositely arranged. According to the self-powered sensing device for monitoring vibration of the ocean structure, the friction nano power generation technology is used for converting vibration energy of the ocean structure in ocean current into electric energy, vibration of the ocean structure is monitored at the same time, use is more convenient, and monitoring is more stable.

Description

technical field [0001] The invention relates to the technical field of vibration sensors, in particular to a self-powered sensor device for monitoring the vibration of marine structures. Background technique [0002] In modern society, with the increasing demand for marine resources, more and more attention has been paid to the status monitoring of marine structures that transport marine resources. Marine structures are widely used in marine development. At the same time, due to the complex environmental conditions, structures It is easy to be damaged, and vibration is an extremely serious factor that damages marine structures, so the vibration monitoring of structures is extremely important. In the prior art, for example, the publication number is a device and method disclosed in CN111257213A for the in-situ monitoring of underwater anticorrosion coatings of marine structures. Usually, various sensors are used in these monitoring systems to monitor the state of structures. ...
