A reservoir spillway discharge capacity coordination device

Abstract

This invention discloses a reservoir spillway discharge capacity coordination device, relating to the field of water conservancy construction. It includes two gate tracks, with a gate vertical frame fixedly connected to the upper end of each track, and a gate horizontal frame fixedly connected to the upper end of the vertical frame. A gate is positioned between the two tracks, and an adjustment component is installed inside the gate. A drive component one is installed at the upper end of the gate vertical frame, and a drive component two is installed in the middle of the lower surface of the gate horizontal frame. It adopts a two-stage control architecture with overall opening and closing of the main gate and adjustable elevation of the discharge port on the adjustment plate. Large flows are rapidly discharged through the main gate, while small flows are precisely controlled through the liftable discharge port. This allows for normalized small-flow discharge under wide water level fluctuations. Furthermore, through a pneumatic linkage structure of a top rod, an air storage cylinder, and an airbag, the displacement of the adjustment plate as the water level rises synchronously compresses gas to inflate the airbag, automatically compensating for the water pressure compression of the airbag at high water levels, thus achieving adaptive enhancement of sealing pressure as the water level rises.
