Meanwhile in order to just to again when reduction specified position, retaining box can close the spillway under good guaranteed water level
2, the water in institute's art appearance water-driven component 5 is inputted according to the following formula by aqueduct 12,
Wherein:
Q------- flow；
Ak--- --- exit area；
Hw--- --- acting head at orifice center when free discharge floods when flowing out, upstream and downstream head difference；
μ --- the discharge coefficient of --- -- aperture or pipeline；
G-------- acceleration of gravity.
The checkdam of the application above structure, especially upstream water level open-shut linkage system 4 are designed based on following principles
, i.e., when reservoir level is in normal pool level, tank inlet pipe flow is equal to outlet pipe flow, the water tank of water tank, that is, above-mentioned
Water remains unchanged, and water tank weight opens power required for door less than gate at this time, and gate is in close state；When reservoir upstream is come
When water is more than power station reference flow, upstream water level rises, and water inlet pipe head increases, and water inlet pipe flow is greater than tank drains pipe stream
Amount, water tank weight start to increase, and when water tank weight increases to the pulling force of gate opening needs, gate opening, dam starts to let out
Flood, tank height decline, when water tank reaches water tank cushion cap, gate standard-sized sheet, discharge reaches maximum.
When upland water amount is reduced to less than power station reference flow, reservoir level is begun to decline, tank inlet pipe head drop
Low, the flow of water inlet pipe reduces, and when water inlet pipe flow is reduced to downstream water tank drainage hole flow, water volume in water tank starts to reduce,
Weight starts to reduce, and when water tank weight decreases below gate weight, gate is begun to shut off, and water tank is begun to ramp up, until to complete
Portion closes.
