Abstract

The invention relates to a self-powered rotating device state monitoring device, and mainly solves the problem existing in the prior art that a power supply cable laying workload is large, construction is tedious, a battery is short in power supply endurance. The self-powered rotating device state monitoring device is composed of an electric energy generation unit (3), a monitoring unit (4), a temperature and vibration integrated sensor (5), and relevant power lines and signal transmission lines. The electric energy generation unit (3) is composed of a power generation module, a rectificationand filtering module and a stator winding center height adjusting mechanism. Power generation is achieved through rotation of motor driving end shaft and a electromagnetic induction principle, and thepower is converted into stable dc voltage by the rectification and filtering module, and then power is supplied to the monitoring unit (4), the technical scheme well solves the problem, and the self-powered rotating device state monitoring device can be applied to rotating device state monitoring.

Description

technical field [0001] The invention relates to a self-powered rotating equipment state monitoring device. technical background [0002] Rotating equipment such as motors and pumps are widely used in basic industries such as coal mines, petrochemicals, and electric power production, and play an important role in the production process. Due to the complex structure of the rotating equipment itself, the operating conditions are generally relatively harsh, and the failure rate in various equipment is relatively high. The quality of its operating status is directly related to the continuity and safety of enterprise production. Therefore, on-line monitoring and fault diagnosis of operating parameters such as vibration and temperature of rotating equipment such as motors and pumps are extremely important and necessary to ensure equipment reliability and production safety. [0003] At present, the condition monitoring devices installed on rotating equipment can be mainly divided i...
