AI Technical Summary

Technical Problem

The existing hydrowheel generator vibration and pendulum monitoring equipment has complex structure and is inconvenient to use. The cable connection of the eddy current sensor may lead to unstable signal transmission, affecting the measurement accuracy and the reliability of the sensor.

Method used

A hydrowheel generator vibration and pendulum monitoring device is designed, adopting a bracket, a first monitoring structure and a second monitoring structure, and using two sets of eddy current sensor bodies to couple each other. Through the block structure and push structure of the first fixed structure and the second fixed structure, the cable plug is easily installed and disassembled to ensure that the cable connection is firm.

Benefits of technology

It effectively avoids the instability of signal transmission caused by insolid cable connections, improves measurement accuracy and sensor reliability, and simplifies the installation and disassembly of the cable.

Abstract

The utility model discloses a hydro-generator runout monitoring device, which comprises a support, a first monitoring structure, a second monitoring structure and a connecting shaft, and is characterized in that the first monitoring structure and the second monitoring structure are arranged, and two groups of eddy current sensor bodies are mutually coupled, so that the shaft vibration track of the connecting shaft is monitored; two sets of clamping blocks of the first monitoring structure are extruded, a second spring pushes a cylinder to move towards the upper left side through rebound resilience, after the hand is released, a torsional spring is used for driving a baffle to rotate, limiting of a plug of a cable is relieved, the plug of the cable is conveniently pulled out, and the second monitoring structure moves according to the same principle. The effect of conveniently mounting and dismounting the cable is achieved, the plug of the cable can be effectively prevented from loosening, and the situation that the monitoring precision is affected due to unstable signal transmission caused by infirmness is avoided.
