A hydraulic winch emergency system of a rescue boat retracting and releasing device comprises a hydraulic motor, a brake connected with the hydraulic motor, a motor valve group for controlling the hydraulic motor to rotate, a control valve group for conveying hydraulic oil to the motor valve group, a hydraulic pump for inputting the hydraulic oil into the control valve group from an oil tank, and an emergency pump group. An oil inlet of the emergency pump set is connected with the oil tank, and an oil outlet of the emergency pump set is connected with an oil inlet of the control valve set. A stop valve and an emergency reversing valve are arranged between the control valve set and the motor valve set, the stop valve is located between the control valve set and a port A of the motor valve set, and after the stop valve closes an oil way, hydraulic oil going to the port A of the motor valve set enters the motor valve set through the emergency reversing valve. Through the arrangement of the emergency pump set, the stop valve and the emergency reversing valve, efficient and convenient use of the hydraulic winch under the emergency condition is achieved.
