Flip bucket and drainage structure thereof
The invention provides a flip bucket and a drainage structure thereof. The drainage structure comprises a fixing plate and a pipeline assembly, wherein the fixing plate is provided with a first side wall face and a second side wall face, and the pipeline assembly is installed on the first side wall face. The fixing plate is vertically arranged relative to the water flow direction, and the second side wall face on the fixing plate is located on the downstream of the water flow direction. A through hole is formed in the fixing plate, the pipeline assembly comprises a drainage pipe and a water tank, the water tank is installed on the first side wall face, and the water inlet end of the water tank is communicated with the through hole. And the drainage pipe is communicated with the water outlet end of the water tank. According to the drainage structure, the through holes are formed in the fixing plate, the situation that the embedded fixing plate is scoured under the high-speed water flow condition due to the fact that the holes are too large is avoided, cavitation is avoided, meanwhile, during flood discharge, the high-speed water flow can generate negative pressure suction force at the through holes, the drainage pipe can become an air mixing pipe during flood discharge, the operation safety of the side wall can be effectively protected, and the service life of the drainage pipe is prolonged. And cavitation and cavitation erosion damage at the pre-embedded fixing plate is avoided.
本发明提供了一种挑流鼻坎及其排水结构，该排水结构包括具有第一侧壁面和第二侧壁面的固定板及安装在所述第一侧壁面上的管道组件。所述固定板相对水流方向竖直设置，并且其上的第二侧壁面位于水流方向的下游。所述固定板上开设有通孔，所述管道组件包括排水管和水箱，所述水安装在所述第一侧壁面上，且所述水箱的入水端与所述通孔连通。所述排水管与所述水箱的出水端连通。本发明的排水结构通过在固定板上设置通孔，避免开孔过大在高速水流条件下对预埋固定板的冲刷，避免产生空化，同时，泄洪时高速水流在通孔处会产生负压吸力，排水管在泄洪时会成为一个掺气管，可以有效保护边壁运行安全，避免预埋固定板处产生空化空蚀破坏。
