The invention relates to the technical field of elevators, in particular to an elevator pit accumulated water automatic pumping and security control method and device. According to the working principle, when accumulated water in an elevator pit exceeds a predetermined control water level, a floating block type switch trigger mechanism starts a water pump arranged at the bottom of the elevator pit to start to pump water; when the pumping speed of the water pump is not high enough to balance the speed of external water entering the pit and the accumulated water reaches the safety control water level, the floating block type switch trigger mechanism starts an elevator control switch and calls a program preset in an elevator control chip to stop an elevator on a designated floor and close the elevator when no one is in the elevator. The elevator pit accumulated water automatic pumping and security control device designed according to the working principle comprises the water pump, a water pump control switch, the elevator control switch and the floating block type switch trigger mechanism, and is characterized in that the floating block type switch trigger mechanism comprises a floating block, a sliding sheet, a baffle block and a mounting structure. The elevator pit accumulated water automatic processing device has the advantages of being ingenious in design, convenient to mount, capable of being directly used on an existing elevator and the like, improves the running safety of the elevator and is low in manufacturing cost, reliable in use and convenient to maintain.
