Abstract

本發明涉及一種用於排水井上端或獨立的明渠進水口的環保渠口閘。本發明是置於明渠進水口(1)中，用鋼碼或其它有效的方式固定。其特徵在於本發明由門框、導流板(2)、密封板和活門(3)組成一個密封間，活門(3)只能向裏打開。由於活門(3)設計處於常閉狀態，用於防臭、防蚊，但不會阻擋水流進入下水道。本發明提供一種結構簡單、使用方便、密封性強的下水道沙井立式明渠進水口防鼠、防蚊、防臭裝置，不會阻擋水流進入下水道，但有效地阻隔老鼠、蚊子、臭氣從下水道向外擴散。The invention relates to an environmental protection channel gate used for the upper end of a drainage well or an independent open channel water inlet. The invention is placed in the open channel water inlet (1) and fixed by steel code or other effective methods. It is characterized in that the invention is composed of a door frame, a deflector (2), a sealing plate and a trap door (3) to form a sealed room, and the trap door (3) can only be opened inward. Since the valve (3) is designed to be in a normally closed state, it is used to prevent odor and mosquitoes, but it will not block water from entering the sewer. The invention provides an anti-mouse, anti-mosquito, and anti-odor device for the vertical open channel water inlet of a sewer manhole with simple structure, convenient use and strong sealing. External diffusion.
