HYDRAULIC FLOODGATE STRUCTURE FOR PREVENTING WATER POLLUTION

摘要

A hydraulic floodgate structure for preventing water pollution is provided to prevent water pollution by sprinkling and discharging the deep water of stored water according to the water level and guiding the movement of stored water. A hydraulic floodgate structure for preventing water pollution comprises: a floodgate(10) installed to a drainageway(2) of a bank(1) for a river or a reservoir to open and close the drainageway; an operating unit installed to the floodgate to rotate the floodgate; many primary pipes installed to the floodgate and opened in one direction to contact with stored water smoothly; an opening/closing unit composed of a primary buoy installed in the primary pipe to move vertically according to the water level and to open and close the opened side of the primary pipe, and a rod member installed on the primary buoy to have a gap from the closed side of the primary pipe and to control the movement of the primary buoy in the gap; sprinkler pipes(50) installed on the floodgate to make one end face upward and to sprinkle water outward; many secondary pipes(60) installed along the backside of the bank and opened in one direction to contact with stored water smoothly; channels(70) formed to penetrate the lower part of the bank to discharge the stored water; and a channel opening/closing unit installed to the inside of the secondary pipe to open and close the channel.
