Bridge body ship collision prevention normally submerged type wharf boat anchoring stress air bag front-mounted blocking system

The invention discloses a bridge body ship collision prevention normally submerged type wharf boat anchoring stress air bag front-mounted blocking system. Flexible intercepting facilities are arrangedin a front-mounted normally submerged mode, and an early warning system is used for inflating an air bag through magnetic induction controlled triggering and enabling the air bag to emerge from the water surface. The bridge body ship collision prevention normally submerged type wharf boat anchoring stress air bag front-mounted blocking system comprises a ship collision prevention intercepting device, the early warning system, an inflating system and a power supply system, wherein the ship collision prevention intercepting device is a flexible intercepting device and comprises the bag type airbag installed between two wharf boats; the early warning system comprises a magnetic inductor array arranged through underwater steel cables tied between the wharf boats on the two sides; the ship collision prevention interce
