Oil pressure rotary swing type waterproof gate control device

The invention provides an oil pressure rotary swing type waterproof gate control device. According to the oil pressure rotary swing type waterproof gate control device, a piston rod of an oil pressurecylinder is operated to act through a controller to execute gate closing or gate opening return control over a waterproof gate; in the gate closing process, whether or not proximity is achieved is detected through a proximity detector; the waterproof gate closely abuts against two stand columns, the proximity detector performs detection and outputs a proximity sensing signal to the controller; the controller starts to compare an input pressure value signal with a built-in pressure data set value when receiving the proximity sensing signal, and controls an oil pressure loop for switching of oil ways when the pressure value signal is equal to the pressure data set value to stop the piston rod from pressurizing the waterproof gate, so that the waterproof gate is tightly pressed on a sealingstrip between the two stan
