The Hydraulic Elevator Dam is composed of an arc (or straight line) dam surface, hydraulic rods, strut bars, hydraulic cylinders and a hydraulic pump station. It adopts the dump-truck mechanics theory, combined with a buttress dam hydraulic structure, and has dual functions of retaining water and discharging water. Hydraulic cylinders stand erectly at the back of the dam and control the pulley movement of sliding strut bars. These cylinders are used for lifting the dam for blocking water, or for lowering the dam in the case of a flood discharge. An inhibiting device controls the pulley movement of sliding strut bars, which is used to support the pier dam's fixed and movable exchange. A buoy switch is used to control the operations of the hydraulic system. The automated system allows for the lifting and the lowering of the dam according to flood fluctuation, and as such, may be left unsupervised. The dam surface may have different colors and designs. The height of the dam may be adjusted for demonstrations. The upstream water forms large waterfalls and water promenades for visitors. The hydraulic system operates easily and requires much less time to lift and drop the dam compared to other types of dams. Therefore, it is suitable for hilly areas where there are sharp fluctuations in flood conditions. The hydraulic elevator dam is able to withstand severe mud and sand sedimentation. It was specially designed for this purpose. The hydraulic dam may be adjusted up to a vertical angle of 75 degrees. This angle is large enough to completely wash away sedimentation under normal flow conditions. If sedimentation is not completely removed, the remainder will not be significant enough to affect the lifting and the dropping of the dam. For areas without electricity, manual control can be achieved, its metal structure is the same as the hydraulic elevator dam, the power is powered by hand pump or diesel engine. For a river with multiple gates, only one mobile diesel engine is needed. Compared to the hydraulic elevator dam, investment will save about 30%-40%.
