State Grid Yangzhou Power Supply Company's sixth-generation intelligent flood barrier early warning system integrates aluminum alloy flood panels with smart sensing technology and has been deployed across 12 provinces and municipalities. Its core comprises a "three-piece flood defense suite": aluminum alloy flood panels with 99% water retention, automatic drainage devices, and water-absorbing expansion bags, enabling comprehensive flood protection for critical sites like substations and hospitals. When water levels in cable trenches reach preset thresholds, the system automatically initiates drainage. If levels continue to rise, it calculates the time remaining until the warning level is reached and remotely alerts personnel. The flood barriers' integrated warning sensors support both scheduled automatic inspections and remote manual checks. Paired with water-absorbing bags that expand tenfold within two minutes of contact with water, the system forms an integrated "block, drain, alert" defense, significantly reducing manual monitoring costs.
