AI Technical Summary
In existing technologies, vortex-eliminating structures are not well-suited for use in coastal power plant water intake projects. They are prone to vortex-induced vibration, blockage, and flow instability. Furthermore, tidal fluctuations can cause device failure, affecting the safety and efficiency of pumping stations.
Several vortex-suppressing ring plates are located above the pump room inlet. Combined with pressure pulsation sensors and lifting components, the position of the vortex-suppressing ring plates is adjusted according to the tangential velocity and vortex frequency of the vortex. The axial movement of the ring plates blocks the formation of vortices, adapts to changes in tidal level, and avoids new vortex vibrations and flow resistance.
It significantly extends the time window for intake vortex formation, reduces the ineffective operation time of the vortex suppression device, improves pump station efficiency, reduces safety hazards, and has good application prospects.
