Retractable vertical-seam inlet flush gallery
The invention discloses a retractable vertical-seam inlet flush gallery, and relates to the field of water resources and hydropower engineering, and provides a flush gallery whose water inlets are not easy to block, and sediment in front of each water inlet can flow away. The retractable vertical-seam inlet flush gallery comprises a main gallery and a plurality of water inlets arranged along a water flow direction. The water inlets are communicated with the main gallery. The water inlet comprises a rectangular inlet front port and a rectangular inlet rear port. Shapes and sizes of the inlet front ports are the same, and height of the inlet front port is larger than width. Width of the inlet rear port is consistent with the width of the inlet front port. The height of the inlet rear port is smaller than the height of the inlet front port. Height of the inlet rear port on flow downstream is smaller than the height of the inlet rear port on flow upstream. Contraction ratios of the water inlets are different, so flow velocity differences of the water inlets are obviously reduced, and the water inlet on the upstream end of the gallery can satisfy desilting requirement. Height of the water inlets is relatively large, and conditions of complete sediment blocking are not easy to occur.
