Abstract

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.

Example Embodiment

[0018] Adopting the method principle of automatic water pumping and safety control of elevator bottom pit water accumulation of the present invention, a kind of elevator bottom pit water accumulation automatic pumping and safety control device designed, elevator bottom pit water accumulation automatic water pumping and safety control device are characterized in that : When the water pump pumping is not enough to balance the speed of external water entering the bottom pit, and when the accumulated water reaches the predetermined safe control water level, the floating block switch trigger mechanism starts the elevator control switch, calls the program preset in the elevator control chip, and the elevator Stop to the designated floor, and close the elevator when there is no one there.

[0019] Preferably, the elevator pit water automatic pumping and safety control device includes a floating block switch trigger mechanism including a mounting plate 1, a water pump control switch mounting plate 2, a water pump control switch 3, a water pump control switch striker plate 4, self-tapping screws 5, Elevator control switch 6, switch plate 7, floating block 8;

[0020] Preferably, the water pump 11 is installed in the elevator pit through the water pump base plate 10, and the floating block type switch trigger mechanism 9 is installed on the elevator shaft wall 12 of the pit.

[0021] Preferably, during work, the switch beating plate 7, the self-tapping screw 7 and the floating block 8 fixed on the water pump control switch strike plate 4 are lifted up and down in the guide groove of the mounting plate 1 by the buoyancy of the bottom pit water. When there is no water in the bottom pit or when there is little water, the water pump control switch hits plate 4 and is restricted on the mounting plate 1 by self-tapping screw 5 at the lowest position. When the accumulated water in the bottom pit reaches the predetermined control water level, the water pump control switch hits the plate 4 to touch the water pump control switch 3, and the water pump 11 is started to work to pump out the accumulated water in the bottom pit; When the predetermined safety control water level is reached, the switch plate 7 can touch the elevator control switch 6, and the elevator is connected to the elevator through the switch control line 13, and the program preset in the elevator control chip is called to stop the elevator to the designated floor. close the elevator.

[0022] Preferably, the water pump control switch adopts a micro switch;

[0023] Preferably, the number of self-tapping screws 7 is 1;

[0024] Preferably, the quantity of self-tapping screws 7 is 2;

[0025] Preferably, the preset control water level that can be adjusted by the installation position is designed to be 100mm;

[0026] Preferably, the predetermined safe control water level adjusted through the installation position and the installation length of the water pump control switch is set to 300mm.
