Problems solved by technology

For strong tidal estuary areas, due to the large tidal range in the open sea, the excessive flow velocity during flood discharge can easily cause scour under the gate, endangering the safety and stability of the gate and surrounding buildings
[0003] In order to reduce scour under the sluice, some projects adopt the structural form of multi-stage stilling basin or multi-stage stilling teeth, but for the sea-exiting sluice, especially the tidal river section, the elevation of the wing walls on both sides of the stilling basin will be reduced,

Abstract

The invention discloses an energy dissipation and scour prevention device for a sea gate. The energy dissipation and scour prevention device comprises an energy dissipation mechanism, a power generating mechanism, a compressed air generating mechanism and a scour prevention block, wherein the energy dissipation mechanism is arranged on a foundation at a drain opening of the sea gate and is used for performing hedging energy dissipation by utilizing water body energy; the power generating mechanism is arranged at the drain opening of the sea gate and is used for converting kinetic energy of a water body into electric energy; the compressed air generating mechanism is connected with the power generating mechanism, and electric energy is provided for the compressed air generating mechanism bythe power generating mechanism so as to generate high-pressure compressed air; and the scour prevention block is arranged on the foundation at the drain opening of the sea gate, is located behind theenergy dissipation mechanism and is connected with the compressed air generating mechanism, and the scour prevention block is used for spraying the high-pressure compressed air generated by the compressed air generating mechanism upwards so as to offset residual kinetic energy of the water body. The energy dissipation and scour prevention device has the advantages of no additional energy consumption, integration of energy dissipation and conversion, greenness, environmental friendliness, high degree of automation, low later maintenance cost and good economy.
