Ship lock double-layer water conveying system with longitudinally-through drainage type lock bottom
The invention relates to a ship lock double-layer water conveying system with a longitudinally-through drainage type lock bottom. The ship lock double-layer water conveying system comprises a ship lock chamber, a first diversion port, a middle branch gallery, a second diversion port, water conveying main galleries located on two sides of the ship lock chamber, filling valves arranged on the upstream portions of the water conveying main galleries, and drain valves arranged on the downstream portions of the water conveying main galleries; the water conveying main galleries communicate with an inlet of the first diversion port through T-shaped pipes, and an outlet of the first diversion port communicates with the second diversion port through the middle branch gallery; the second diversion port communicates with the third diversion port located in the upper layer through a vertical shaft, the third diversion port communicates with a water drainage branch gallery, and the water drainage branch gallery communicates with water drainage holes, and energy dissipation cover plates are arranged on the water drainage holes; and the elevations of the first diversion port, the middle branch gallery and the second diversion port are consistent with those of the drain valves, and the third diversion port, the water drainage branch gallery, the water drainage holes and the energy dissipation cover plates are located on the elevation surface of a lock chamber bottom plate. According to the ship lock double-layer water conveying system, the pressure characteristics of the diversion ports canbe improved to avoid cavitation and cavitation erosion, moreover, outflow can be dispersed to the maximum extent, and the water conveying safety and the water conveying efficiency of the ship lock are improved.
一种闸底纵向贯通式出水的船闸双层输水系统，包括船闸闸室、第一分流口、中支廊道、第二分流口、位于船闸闸室两侧的输水主廊道、分别设于输水主廊道上游和下游的充水阀门和泄水阀门，输水主廊道通过T型管与第一分流口的进口连通，第一分流口的出口通过中支廊道与第二分流口连通，第二分流口通过竖井与位于上层的第三分流口连通，第三分流口与出水支廊道连通，出水支廊道与出水孔连通，出水孔上部设有消能盖板，第一分流口、中支廊道及第二分流口的高程与泄水阀门高程保持一致，第三分流口、出水支廊道、出水孔、消能盖板位于闸室底板高程面。本发明可改善分流口压力特性以避免空化空蚀，还可最大幅度的分散出流，提高船闸输水安全性及输水效率。
