<p>The present invention relates to a multilayer floodgate structure opening multiple floodgates in a terraced type in a deep waterway. To adjust the open heights of the floodgates and safely manage the floodgates by lowering the exposure heights of the completely open floodgates, the present invention is composed of hydraulic turbine blades attached to both sides to lift multiple opening protrusions and a blade track upward along a multilayer floodgate track formed to be terraced according to the water level of the waterway including a pier and a winding device lifting the lowest floodgate by normally and reversely rotating a screw-type shaft in a winding nut fixed to the lowest floodgate among the multiple floodgates having the multiple floodgate protrusions attached on the lower part or both of the lower and upper parts. The present invention is characterized by completely opening the waterway from the sea bottom to the water-storable level by gathering the floodgates on the upper part of the pier by supporting the highest floodgate using the lowest floodgate until the highest floodgate is locked by the opening protrusions and overlapping the highest floodgate on the other floodgate for the last or completely closing the waterway by adhering to the lowest floodgate to a hydraulic turbine base for the last, adjusting a power generation amount or a water passing amount by partly opening at the open height of the lowest floodgate, limiting the exposure height when the floodgates are completely opened at the water-storable level or a level around a towing port, and protecting the floodgates from strong wind waves by gathering the floodgates together.</p> |
