Early warning device for bridge structure monitoring

By designing an early warning device for bridge structure monitoring, using springs and guide grooves in conjunction with bridge expansion joints, the guide rail drives the rod to rise and fall and press the early warning button, solving the problem of vehicle tire damage caused by differences in bridge height, and realizing real-time monitoring and remote early warning of differences in bridge height.

AI Technical Summary

⚠Technical Problem

The difference in bridge height on both sides of the bridge expansion joint can cause damage to vehicle tires, and existing technologies lack an effective early warning mechanism.

⚗Method used

Design an early warning device that uses the spring's telescopic properties in conjunction with bridge expansion joints, and utilizes guide grooves and guide rails to drive the pole to rise and fall. When the guide wheel presses the early warning button, the signal is transmitted to a remote signal transmitter and then remotely to a monitoring system.

🎯Benefits of technology

It enables real-time monitoring and early warning of differences in bridge height, allowing staff to be notified promptly for bridge maintenance and preventing damage to vehicle tires.

Abstract

This utility model discloses an early warning device for bridge structure monitoring, including a telescopic mechanism, a triggering mechanism, and a remote signal transmitter. The telescopic mechanism includes a guide frame, a spring disposed on the side wall of the guide frame, and a guide rail disposed on the side wall of the spring. The triggering mechanism includes a rod disposed on the side wall of the guide rail, a guide wheel disposed on the side wall of the rod and moving along the guide rail, and an early warning button disposed inside the guide rail. The remote signal transmitter is electrically connected to the early warning button and is remotely connected to a monitoring system. In this utility model, the guide rail drives the rod to rise and fall as the height of the bridge on both sides of the expansion joint changes. The guide wheel on the side wall of the rod moves along another guide rail until the early warning button is pressed, indicating that the height difference between the bridge on both sides of the expansion joint is large, posing a risk of vehicle tire damage. The remote signal transmitter can remotely transmit signals to the monitoring system.
