Performance characteristics and working principle of hydraulic dam

Hydraulic dam is a revolutionary achievement of water conservancy technology and a leading active dam technology. It is widely used in agricultural irrigation, fisheries, ship locks, gates, tidal blockage of seawater, blockage, urban river phenomenon engineering and small hydropower stations. The mechanical structure of the hydraulic steel dam is scientific, without water accumulation and siltation, and it is not affected by floating objects; in the case of less water loss, it can simply wash away the floating objects that go upstream, making the river channel flat, and the dam can be released quickly without affecting the flood control safety flow. The flow becomes flat, and the dam can be released quickly without affecting the flood control safety; the structure is stable and reliable, with strong flood resistance and strong impact resistance. It overcomes all the shortcomings of the traditional active water dam type and also has all the advantages of the traditional dam type. It is close to the riverbed like a rubber dam without blocking water. It is like a gate dam, which can automatically release the dam for flood discharge and can be attached to the water level at will. It is stable like a gate and also has a dam type of rubber.

At present, the widely used steel dam types are multi-hinge shaft type, type, double-pivot composite type, type, multi-hinge link sliding type and sliding support hinge type. The hydraulic steel dam was established in China in 2006 and belongs to the third generation of river dams. It uses the mechanical principle of a dump truck to build a dam. It is a hydraulic structure dam with water-saving and flood discharge functions. It is mainly composed of a dam surface (arc or straight line), support rods, hydraulic rods, hydraulic cylinders and hydraulic pump stations.

The main working principle of the hydraulic dam is to use the hydraulic system to control the active dam, then stop the water flow when reaching the rising dam, and release the flood when the dam is lowered. The structure of the hydraulic steel dam is to form a stable supporting pier dam without a non-sliding support rod as a support for the dam surface. Through the hydraulic system and the limit card equipment, the movement and fixation of the supporting pier dam can be converted to each other, so as to achieve the purpose of fixed water retention and active dam lowering. In addition, the hydraulic steel dam can operate the hydraulic system through the buoy switch to complete automatic processing and lift the active dam surface in real time according to the fluctuation of the flood.
