Abstract

A water tank is arranged in the ground of the elevator car, a water collecting device connected with the water tank is arranged at the bottom of the elevator car, a water outlet and a switch support enabling the water collecting device to drain water are arranged in a bottom pit of an elevator shaft, and water is automatically drained when the elevator car reaches the bottom layer. The structure is simple, the cost is low, the car ground is designed to have a certain gradient, and water on the car ground is effectively and automatically collected; a floating switch, a switch support, a switch valve and a switch connecting rod are designed, so that rapid, intelligent and automatic drainage can be achieved on the premise that operation of the elevator is not hindered, and extra waterproof measures do not need to be added to the elevator and peripheral equipment.
