The utility model relates to an electrically-driven underwater emergency safety control system. The electrically-driven underwater emergency safety control system is characterized by comprising a trigger device, an electric control device, a power device, a plurality of blowout preventer executive devices, a plurality of electric pump devices and a liquid storage device, the electric control device, the power device and the electric pump devices are placed in a sealed shell filled with insulating liquid, and the blowout preventer executive devices and the liquid storage device are arranged outside the sealed shell. The structure of the electrically-driven underwater emergency safety control system is more compact, purchase cost is saved, and the space occupied rate is reduced. The electrically-driven underwater emergency safety control system is located near a seabed well mouth and can guarantee safety of equipment and personnel, protect the environment, and reduce losses to the maximum degree when blowout accidents occur, and a marine drilling platform well control system cannot reliably shut in a well in time. The electrically-driven underwater emergency safety control system can be widely applied to the fields of sea scientific investigation and the like.
