The utility model relates to the technical field of water supply equipment, in particular to an electromechanical double-control water replenishing device. According to the electromechanical double-control water replenishing device, an electromagnetic valve is connected to a water supply pipeline, and when a floating ball valve works normally, the electromagnetic valve is in an open state; the high water level sensor and the low water level sensor are embedded in the inner wall of the box body; the height of a sensing part of the high-water-level sensor is higher than the liquid level of waterin the water replenishing cavity when the ball float valve is in a fully-closed state; the control module is electrically connected with the electromagnetic valve and the liquid level sensor and usedfor receiving electric signals sent by the high-water-level sensor and the low-water-level sensor and controlling the electromagnetic valve to be closed or opened. When the ball float valve breaks down, the control module rec
