AI Technical Summary

Technical Problem

Existing methods for monitoring steel structure deformation are inefficient and costly, lack intuitive on-site display and instant alarm functions, and are difficult to achieve real-time monitoring and rapid risk assessment.

Method used

The system uses a hydraulic cylinder and support unit to monitor steel structure deformation by changing the hydraulic oil level. It uses an image sensor to identify the liquid level position and trigger an alarm. Combined with a one-way valve, it prevents hydraulic oil backflow, simplifies installation, and adapts to different working conditions.

Benefits of technology

It achieves highly sensitive real-time deformation monitoring without the need for manual supervision, reducing equipment costs and complex installation requirements, providing instant alarms and quantitative data, and improving the reliability and applicability of monitoring.

Abstract

The application relates to a building steel structure deformation monitoring warning device, and belongs to the steel structure deformation monitoring device field. The device comprises a hydraulic cylinder body, a supporting unit and a display tube. The hydraulic cylinder body is arranged on the lower flange of a cross beam. The supporting unit is arranged in the hydraulic cylinder body in a vertical sliding mode, and the top of the supporting unit abuts against the upper flange of the cross beam. A liquid outlet hole is formed in the side wall of the hydraulic cylinder body. A one-way flow valve is arranged in the liquid outlet hole. The display tube is arranged on the cross beam. The display tube is provided with a display window. The display tube is in communication with the inside of the hydraulic cylinder body through the one-way flow valve. An image sensor is arranged at the display window. The image sensor is used for identifying the liquid level at the display window. The image sensor is electrically connected with an alarm. The application has the technical effects of monitoring the cross beam change in real time and visualizing the cross beam deformation.
