CONSTITUTION: A sewage shielding device for drainage comprises a first frame(110), a first guide plane(120), a second guide plane(130), and a first opening and closing plate(140). The first frame is placed on a top protrusion(30) of a connection hole(10) connected to drainage. The first guide plane is integrally coupled to one side of the first frame and is inclined downward. The second guide plane is integrally coupled to the first frame in the opposite direction to the first guide plane. One side of the first opening and closing plate is coupled to the first guide plane through a hinge(160a), and the other side touches the end of the second guide plane. |
