AI Technical Summary

Technical Problem

In existing technologies, when hydropower station unit bearings experience abnormal friction, poor lubrication, or excessive load, the temperature rises sharply, leading to journal wear. This cannot be monitored in real time, resulting in late-stage fault handling.

Method used

An installation mechanism is provided, including a base frame, a positioning component, and a protective component, to ensure that the temperature sensor is in close contact with the outer wall of the bearing, and is equipped with an early warning device, including a temperature sensor, a temperature transmitter, a buzzer, and an LED light, to realize real-time temperature monitoring and early warning.

Benefits of technology

This technology enables real-time monitoring and timely early warning of bearing temperature in hydropower station units, preventing journal wear caused by temperature rise and improving the timeliness and reliability of equipment maintenance.

Abstract

This utility model relates to the field of hydropower station unit monitoring technology, specifically an installation mechanism and early warning device. It includes a base frame component, which is the part connecting the mechanism to the surface of the bearing to be monitored. The base frame component includes a mounting frame and ear plates disposed on the side of the mounting frame, the ear plates providing positioning and fixing for the base frame component; a positioning member, disposed inside the base frame component, which can slide on the base frame component. After the base frame component is connected to the outer wall of the bearing, the position of the positioning member can be adjusted to flexibly adjust the monitoring surface according to the actual installation situation, ensuring that the sensor parts are as close as possible to the outer wall of the bearing in different installation environments; and a protective member, disposed on the side of the base frame component, covering the positioning member on the side of the base frame component to protect the positioning member.
