Utility model content
the purpose of this utility model is, provides the device of a kind of power station stratified pumping, substitutes existing stop log gate with the butterfly valve of one group of differing heights, and without the need to arranging Emergency Gate, intake tower width can reduce, and reduces investment outlay; Because the active water of butterfly valve is closed, when stop gate operation troubles, also active water is closed and is blocked current, and the safe operation for power station increases guarantee together.
the technical solution of the utility model:
a device for power station stratified pumping, comprises power station intake tower; It is characterized in that: the upstream face of power station intake tower is provided with trashrack; The back side of trashrack is provided with waterwall, and be provided with the penstock of one group of column distribution by row in waterwall, penstock is provided with butterfly valve; The back side of waterwall is provided with stop gate.
in aforementioned means, in described waterwall, the bearing strength of butterfly valve from top to bottom increases progressively.
in aforementioned means, described waterwall is divided into two sections from top to bottom, and the thickness of epimere body of wall is uniform thickness wall, and the thickness of hypomere body of wall is the trapezoidal wall of progressive additive from top to bottom.
in aforementioned means, the often row butterfly valve in described waterwall connects by operating room, and operating room two ends are provided with the cat ladder towards intake tower top, power station.
in aforementioned means, described penstock two ends are circular arc horn mouth.
in aforementioned means, the penstock below the level of dead water of described power station intake tower is provided with former and later two butterfly valves, and the butterfly valve of upstream face is service valve, and the butterfly valve of back side is operating valve.
compared with prior art, the highly different butterfly valve of the utility model substitutes the stratified pumping that existing stop log gate realizes real meaning.Without the need to arranging Emergency Gate after butterfly valve, intake tower width can reduce, and reduces investment outlay.Penstock two ends are horn mouth, smooth in water flow, and HYDRODYNAMIC CONDITION RELATING TO is good.Twice butterfly valve is set below level of dead water, when wherein one butterfly valve has fault, without the need to sluicing, does not affect generating, closing another road butterfly valve and still can complete service work.Butterfly valve is provided with operating room, and operating room two ends arrange cat ladder and pass to tower top, can realize operation and the maintenance of butterfly valve.The active water of butterfly valve is closed, and when stop gate operation troubles, also active water is closed and blocked current, and the safe operation for power station increases guarantee together.
