The present invention provides a liquid discharge gate device, which includes: a fixing tube having an end fixed to a liquid discharge hole of a liquid storage device and a tube wall defining one or more liquid input holes, wherein the liquid input holes are in communication with the liquid discharge hole of the liquid storage device through the interior of the fixing tube and a moveable tube capable of being moveably inserted in the fixing tube in a lifting manner so that the moveable tube can be moved in a lifting manner between a closed position of the liquid input hole and an opened position above the liquid input hole. When the moveable tube is at the closed position, the liquid of the liquid storage device can be blocked from flowing to the liquid discharge hole through the liquid input hole. When the moveable tube is at the opened position, the liquid of the liquid storage device is allowed to flow to the liquid discharge hole through the liquid input hole. As a result, it is able to achieve the purposes of fast opening and closing the liquid discharge hole of the liquid storage device and performing operation and control by manual operation, electrical control, far-end remote control or other motive power.本發明係提供一種排液閘門裝置,其包含:一固定管,其一端用於固定在儲液裝置的排液孔上,其管壁設有一個以上的進液孔,使進液孔通過固定管的管內連通儲液裝置的排液孔;及一活動管,其可升降活動地穿設在固定管內,使活動管可在進液孔的一封閉位置,與進液孔以上的一開放位置之間升降移動,當活動管在封閉位置時可阻擋儲液裝置的液體從進液孔流通到排液孔,當活動管在開放位置時則開放儲液裝置的液體從進液孔流通到排液孔,藉此達到快速地開啟與封閉儲液裝置的排液孔,及可手動操作、電動控制、遠端遙控或以其他動力操作控制等目的。1‧‧‧固定管11‧‧‧進水(液)孔12‧‧‧限位部121‧‧‧縮口部13‧‧‧第一延伸管2‧‧‧活動管21‧‧‧阻水(液)管22‧‧‧第二延伸管3‧‧‧電動致動裝置31‧‧‧電動機32‧‧‧活動軸
