Abstract
The utility model belongs to the technical field of civil air defense door drainage, and particularly relates to a civil air defense door drainage structure which comprises a body, installation shafts are fixedly installed at the top and the bottom of the body, sealing strips are fixedly installed on the outer side of the body, first filter screens are fixedly installed on the two sides of the body, and the number of the first filter screens is two. Through cooperation of a first filter screen, a second filter screen, a first drainage groove, a water level probe, a water pump, a water pumping pipe, a second drainage groove, a built-in power source and a water level probe power supply pipe, liquid can be filtered through the first filter screen and the second filter screen, the situation that large impurities affect the drainage efficiency is prevented, and when the water level is low, water can be drained through the first drainage groove; when the water level probe detects that the water level reaches a certain height, the built-in power supply can supply power to the water pump through the water level probe power supply pipe, the water pump can control the water pumping pipe to pump water, and the water is discharged outwards through the second drainage groove, so that the drainage function is achieved.
