AI Technical Summary
The existing wire rope displacement sensors of hydraulic gate hoists are susceptible to entanglement and corrosion from downstream floating objects, leading to measurement deviations and operational instability, which affects the opening and closing accuracy and stability of the arc gate.
The wire rope displacement sensor is installed above the side wall of the hydropower station dam, and the movement of the wire rope is guided by a guide pulley structure to avoid tangling and wear. High-strength materials are used to improve anti-interference performance and operational stability.
This effectively reduces sensor vibration issues, while improving the equipment's anti-interference performance and operational stability, enhancing gate control accuracy, and reducing maintenance frequency.
