Abstract

The invention relates to a ship machine vibration self-driven sensing device based on a friction nanometer generator. The ship machine vibration self-driven sensing device comprises the friction nanometer generator, a signal processing circuit and an attaching fixed layer. The friction nanometer generator comprises a base, a top cover, a metal electrode, a contact layer and liquid metal. Hemispherical pits are formed in the base and the top cover; the metal electrode is fixedly connected to the inner surface of the pit of the base; the contact layer is fixedly connected to the inner surface of the metal electrode; the liquid metal is arranged between the base and the top cover and can freely vibrate in the spherical space; one end of the signal processing circuit is connected with the friction nanometer motor, and the other end is grounded; the attaching fixed layer is fixedly connected to the bottom side of the friction nanometer generator. The device is small in size, light in weight, low in cost, high in environment compatibility and capable of converting vibration information of the ship mechanical equipment with low and medium frequency motion characteristics into electric signals, and self-driven vibration sensing of the ship mechanical equipment is achieved.

Description

technical field [0001] The invention relates to the technical field of vibration sensing, in particular to a ship engine vibration self-driving sensing device based on a friction nanogenerator. Background technique [0002] The upgrading of sensor technology is a challenge and a major demand for the development of smart ships in my country. The research and development of new ship machinery vibration sensing technology and the improvement of the vibration monitoring level of ship engine room equipment have great value and practical significance for the intelligent operation and maintenance of equipment and health management. The intelligent process of the shipbuilding industry and an important measure to drive industrial upgrading. [0003] In terms of marine vibration sensors, there are mainly two types of electromagnetic type and eddy current type at present, but these two types of sensors need to be powered by cables in the process of generating signals. However, the vibr...
