Sliding Gate Apparatus to prevent Inserting earth and sand to intake water naturally at Intake Station

摘要

The present invention relates to a sliding gate apparatus to naturally take water and prevent inflow of earth and sand in a water intake station, capable of preventing earth and sand from flowing in a water intake pipe when a water level is lowered in the water intake station. According to the present invention, the apparatus comprises: an underwater pump placed at a constant height from a floor under the water of the water intake station to pump up the water to supply the water to a water purification plant; an earth and sand inflow prevention cage to seal a bottom surface of a rectangular basket shape to surround the underwater pump and having a side surface formed with comb teeth having a gap; a water intake pipe connected to the underwater pump to transfer the water to the water purification plant; a screen through which the water intake pipe is penetrated; a fixation/support part of an L shape to support the screen; a screen fixation part to fixate the fixation/support part to the screen between the screen and the fixation/support part; a safety footplate coupled to the fixation/support part ; a floodgate fixation part coupled to left and right sides of the safety footplate to fixate a floodgate; a floodgate operation device coupled to the floodgate fixation part to operate the floodgate; a two-stage sliding gate coupled to the floodgate operation device to be vertically moved; and a base part formed in a lower part of the screen and a floodgate of the two-stage sliding gate.
