Description

Sluice gate

Technical Field

The utility model belongs to the technical field of nuclear power station water gates, and particularly relates to a water gate.

Background

When the nuclear power plant normally operates, the forebay steel gate is lifted, the nuclear power plant circulating water pump takes water from the forebay, seawater is conveyed to the condenser after being boosted, and the seawater is discharged into the sea through the circulating water drainage pipe and the siphon well after heat exchange.

When the nuclear power plant is subjected to large-scale maintenance for material changing each time, a plurality of fore pool sluice gates arranged in the vertical direction are arranged below the fore pool sluice gates to support the maintenance of the circulating water pump. And after the maintenance of the circulating water pump is finished, lifting the circulating water pump to prepare for the operation of the circulating water pump and the integral starting of the two loops.

The siphon well of the nuclear power plant is used for collecting the circulating cooling seawater of the nuclear power plant and the wastewater which meets the emission standard through detection. The upper stream is a circulating water pipeline, the lower stream is a siphon well drainage channel, and collected drainage and waste water are drained into the sea by gravity. The siphon well sluice gate provides the siphon well when the power plant normally operates, and waste water can be discharged into the sea through the siphon well drainage pipeline by means of gravity.
