In water conservancy projects, the safe and stable operation of hydraulic metal structures is related to the overall situation.Online monitoring system of gate/hoist In-depth focus on the pain points of failure of hydraulic metal structures, with real-time online monitoring as the core, a complete safety evaluation system has been built to escort water conservancy projects.
1. System overview: Use technology to build a strong security line of defense
There are various forms of failure of hydraulic metal structures, including strength failure, vibration failure, power instability, structural deformation and failure of major components. Through real-time monitoring of key parameters, the system delves into the inherent causes of failure, and refers to authoritative specifications such as "Design Specifications for Steel Gates for Water Conservancy and Hydropower Projects", "Safety Testing Technology for Hydraulic Steel Gates and Open and Close Machines", "Scrap Standards for Metal Structures for Water Conservancy and Hydropower Projects", combined with finite element calculations and verification results, to form a scientificTesting standards provide a solid basis for the evaluation of equipment operation safety and service life.
2. System composition: hierarchical and distributed intelligent architecture

3. Online monitoring system of gate and online monitoring system of hoist: multi-dimensional protection of gate safety
For curved doors, the system is set upFour key monitoring points, to achieve full-dimensional state perception and early warning.
Gate online monitoring system
Online detection system for hoist
Flow excitation vibration monitoring: According to the structure of the gate, sensors are arranged in the larger parts of the vibration response, the monitoring direction is consistent with the direction of structural vibration, and the acceleration, displacement, frequency and other data are captured in real time. When the vibration displacement exceeds the standard or the vibration frequency is close to the natural frequency, the system automatically warns and alarms.
Stress monitoring: Perform stress testing on the main beam, side beam, support arm and other stressed components, combine material characteristics, structural parameters, and load conditions, calculate the working stress according to DL/T5039 and DL/T5167 standards, analyze the static stress value and dynamic stress value, and give timely warning when it exceeds the standard.
Operating attitude monitoring: Monitor the trajectory of the centerline of the gate and calculate the gap between the gate body and the side rail. When the gap exceeds the set value, the system pre-alarms to avoid rail failure.
Monitoring of the working condition of key components: Real-time monitoring of the operating status of key parts such as the hinge shaft and bearings of the arc gate support hinge. If the support hinge bearing is locked, the fixed wheel does not rotate or wears out abnormally, an early warning and alarm will be issued immediately.
Fourth, the application value: the triple optimization of safety, life and cost
Safety and security: Monitor the status of equipment in real time, give early warning of failures, effectively avoid accidents, and ensure the safe operation of water conservancy projects.
Life extension: Through scientific condition monitoring and maintenance recommendations, delay the aging of equipment and significantly extend the service life of hydraulic metal structures.
Cost reduction: Reduce unplanned downtime and maintenance costs, realize efficient and intelligent operation and maintenance, and significantly reduce overall operation and maintenance costs.
5. Application cases: proof of strength from the laboratory to the engineering site
The system has undergone a number of practical inspections of water conservancy projects, and has performed well in the condition monitoring of the metal structure of the gate. It has realized accurate data collection, intelligent analysis and efficient management, and provided customers with reliable technical solutions. It has become an important boost for the intelligent upgrading of water conservancy projects.
