Abstract

The utility model discloses a cover plate for a self-flowing drainage hole in a volute layer of an underground factory building. An inclined bottom plate is arranged at the bottom of an outer frame to enclose a funnel-shaped flow opening, and a grid-shaped cover plate is set in the outer frame; on both sides of the flow opening The rotating shaft is installed, and the rotating shaft is located at the eccentric position of the plane cover; at the same time, a limit plate and a baffle are respectively arranged on both sides of the plane cover, and the plane cover automatically closes the flow opening under the action of gravity. The utility model can realize the automatic closure of the plane cover under the action of its own weight when there is no water; when water falls, the inclined ground is that after the water flow converges, under the action of water pressure, the plane cover tilts to cause water When it flows to a low place, the cover will be opened automatically, and the water will fall into the sewer. It can improve the safety, prevent the underground sewage and smell in the underground factory building from pouring out from the overflow port, and improve the sanitary conditions for long hair. The use effect is good, and it meets the requirements of anti-corrosion, blocking the wind force of the self-flowing drainage tunnel, meeting the drainage of the volute layer drainage ditch and the drainage of the flooded factory building.
