Pivot arrangement structure for water diversion type sub-cascade power station

The utility model belongs to the technical field of water conservancy and hydropower engineering, and particularly discloses a hub arrangement structure for a water diversion type cascade power station, which comprises an upstream cascade tail water outlet, a downstream cascade water diversion inlet and an adjusting pond dam arranged on a riverbed covering layer, and the adjusting pond dam and riverbanks on two sides of the upstream of the adjusting pond dam jointly form an adjusting pond in an enclosing manner; the upstream cascade tail water outlet is communicated with the regulating tank, and the downstream cascade water diversion inlet is formed in the regulating tank. The regulating reservoir jointly defined by the regulating reservoir dam and the river banks on the two sides of the upstream of the regulating reservoir dam has the advantages of being simple in structure, convenient to construct, capable of using local materials, high in water collecting capacity and the like. By means of the hinge arrang
