Anti-clogging building drainage floor drain structure

Abstract

The application relates to the technical field of building drainage floor drains, and discloses a building drainage floor drain structure capable of preventing blockage, which comprises a floor drain shell with an open top structure, a floor drain top plate fixedly installed at the top of the floor drain shell, and a circular-truncated-cone-shaped placing hole communicated with the floor drain shell and arranged at the top of the floor drain top plate. The application has the following advantages and effects: the circular-truncated-cone-shaped drain plate and the filter screen are used in cooperation, double filtration can be realized, the blockage risk can be effectively reduced, when the filter screen is blocked due to long-term use without cleaning, the horizontal floating plate and the vertical floating rod can automatically float up, the horizontal floating plate can be manually rotated to quickly remove the blockage, and after water around the floor drain top plate continuously enters the floor drain shell and is discharged, the horizontal floating plate and the vertical floating rod can automatically drop back to the original position under the action of the gravity, so that the horizontal floating plate and the vertical floating rod are prevented from being higher than the ground and causing the feet of pedestrians to be kicked.
