Description

Automatic drainage device for elevator pit Technical Field The utility model relates to the technical field of elevator drainage, in particular to an automatic drainage device for an elevator pit. Background At present, the elevator is widely applied to various buildings such as residential houses, markets and the like, and the elevator pit has serious ponding condition due to poor waterproof effect of the pit in the building or water inflow in an elevator shaft caused by water pipe breakage, heavy rain and water rising and the like, so that the elevator is a technical problem to be solved urgently in the elevator industry; In the prior art, a user or a property informs an elevator maintenance personnel of the treatment mode of accumulated water in the elevator pit, when the accumulated water is serious, a door of an elevator bottom layer is opened, and a water pump is temporarily installed to pump water; Through retrieving, chinese patent with bulletin number CN216713300U discloses an efficient elevator pit automatic drainage device, its theory of operation is roughly, when the built-in collection intracavity contains ponding, the floater upwards shifts under ponding buoyancy effect, connect the push rod and have driven the striking piece in the control intracavity simultaneously and when contacting with trigger switch's active end, trigger switch transmission signal to drain pump, the drain pump starts in step like this, drain pump draws the ponding of built-in collection intracavity through the drain pipe, but because drain pipe's one end is linked together with the bottom of elevator pit, after the ponding appears in the pit, not only in the pit can store ponding, in the ponding can get into the drain pipe, and the ponding height in the two is the same, because the floater just can trigger the switch after upwards moving one end distance, last ponding in the drain pipe this moment, long-time ponding can make the pipeline inner wall be in the moist state for a long time, easily cause the corruption phenomenon, reduce the life of pipeline.
