OVERTURNABLE AUTOMATIC WATER GATE FOR SPILLWAY OF RESERVOIR

摘要

A non-powered turnover gate of a spill-way of a reservoir is provided to simultaneously satisfy agricultural water security and disaster preventive functions by preventing functions of the gate from being lost. A non-powered turnover gate of a spill-way of a reservoir includes a weight(1), a water gate(2), a cut off plate(3), a drainage portion(4), and a drainage port(5). The weight has a lower portion of a semicircumferential pattern and both ends pivotally disposed at both sides of the spill-way. The water gate is integrally extended from an upper portion of the weight and blocks upstream water in the spill-way. The cut off plate encloses a part of an upstream side of the weight. The drainage portion is mounted between the weight and a lower portion of the spill-way. The drainage port drains water leaked between the cut off plate and the spill-way through the drainage portion.
