AI Technical Summary
The umbilical cables of existing underwater detectors are easily disturbed and impacted in complex hydrological, geological and ecological environments, resulting in unstable signals and low transmission efficiency, especially affecting the stability and accuracy of water level measurements.
An underwater full-signal water level measurement umbilical cable was designed. It adopts a flat ribbon structure and includes an optical fiber communication unit, a power supply unit, and a signal control unit. It uses a stainless steel sheath and single-mode quartz optical fiber to improve the anti-disturbance capability, and enhances electromagnetic interference protection through overlapping wrapping and copper wire braided shielding layers.
It improves the stability and accuracy of underwater detection signals, reduces the specific gravity of the cable, provides radial support, prevents knotting and twisting, improves the transmission efficiency of control signals, and extends the service life of the cable.
