Document Type and Number:
WIPO Patent Application WO/2020/125601
Kind Code:
A1
Abstract:
Disclosed by the present invention is an emptying system for a high dam, comprising a plurality of primary gate devices, secondary gate devices and an emptying gate device which are successively arranged along a flow direction of river water. Each primary gate device comprises an overhaul gate well and a working gate well which are arranged in parallel as well as a power device A and a power device B which are mounted on top; each secondary gate device comprises an accident gate well and a power device C which is mounted on top; the overhaul gate well, the working gate well and the accident gate well may be opened and closed independent of each other; a water replenishing unit which is independently arranged on the exterior is used for replenishing water for the working gate in the second secondary gate device; and the emptying gate device comprises an emptying lock chamber and an arc-shaped emptying gate. By employing the technical solution of the present utility model, pressure of an upstream water head may be shared by the multiple primary gate devices, reservoir water may be emptied by the emptying gate device, water pressure in a system is replenished by the water replenishing unit, so that the flow rate of water may be kept stable, thereby preventing the gate devices from bearing ultrahigh water head pressure and ensuring the safety and stability of the whole system.
