Precision monitoring system of arc gate inclinometer: The posture guardian of water conservancy hubs

The weight of a thousand-pound deviation of 0.1°​
The slight change in the inclination Angle of the arc-shaped gate conceals a danger:

• ​The hinge settles at 0.5°It may lead to the failure of the gate seal, with a leakage rate exceeding 300 liters per second.
• ​Temperature deformation differenceA temperature difference of 40℃ in summer causes metal deformation, which is equivalent to an 8-cm deviation at the end of a 10-meter-span arc door.
• ​Limitations of traditional detection​：
  The accuracy of the bubble level is only ±0.5°
  The electronic inclinometer drifts due to electromagnetic interference
  Manual measurement cannot capture dynamic deformation

​Ii. Core Breakthrough of the System: Micro-radio-level perception​

  ● Z-axis torsion monitoring: Laser interference detection of torsion deformation (accuracy ±0.005°)
• ​Intelligent early warning mechanism​：
  Level 1 Warning: A 0.1° tilt deviation will trigger an audible and visual alarm after 5 minutes
  ▶ Secondary intervention: Automatically lock the hydraulic system when the offset exceeds 0.5°
