摘要
PURPOSE: An apparatus for preventing rainwater and earth from flowing into a storm overflow chamber having an arc-shaped opening and closing plate is provided to prevent a river from becoming contaminated by preventing sewage from flowing into the river. CONSTITUTION: An apparatus for preventing rainwater and earth from flowing into a storm overflow chamber having an arc-shaped opening and closing plate comprises a frame(10), a cover plate(13), a rotary shaft(20), a floating body(40), and an arc-shaped opening and closing plate(30). The frame is installed in a sewage inlet hole formed in a storm overflow chamber. The cover plate is coupled to the top surface of the frame. The rotary shaft is coupled to the bottom surface of the frame through a first connection unit(21). The floating body is ascended and descended depending on the level of water flowing into the storm overflow chamber and rotates the rotary shaft. The opening and closing plate opens and closes the sewage inlet hole.
