Water inlet/outlet body close to draft tube
The invention relates to a water inlet/outlet body close to a draft tube, the water inlet/outlet body comprises a horizontal tunnel section, a bent pipe section, a vertical shaft section, a vertical shaft diffusion section and a diversion section, the rear part of the draft tube is connected with the horizontal tunnel section, and the horizontal tunnel section is connected with the bent pipe section; the bent pipe section is connected with the vertical shaft section, the vertical shaft section is connected with the vertical shaft diffusion section, a flow channel is divided into an upstream part and a downstream part based on an inverted cone of the vertical shaft diffusion section, and the upstream side and the downstream side of the vertical shaft diffusion section are connected with the flow dividing sections correspondingly. The design result of the body type of the water inlet/outlet is determined by the design size of each segment of the body type of the water inlet/outlet determined by the working parameters, the installation parameters and the topographic parameters of the target unit and the actual size of each segment obtained by at least one preset connection constraint. According to the embodiment of the invention, by combining the water flow characteristics of the side type water inlet/outlet and the vertical shaft type water inlet/outlet, the non-uniform flow state after the draft tube is effectively improved, and meanwhile, the good terrain adaptability is achieved, so that the requirements of the water inlet/outlet of the pumped storage power station of the low-water-head ground type factory building close to the draft tube are met.
本申请涉及一种紧接尾水管的进/出水口体型，其中，进/出水口体型包括：水平隧洞段、弯管段、竖井段、竖井扩散段和分流段，尾水管后连接水平隧洞段，水平隧洞段连接弯管段；弯管段连接竖井段，竖井段连接竖井扩散段，并基于竖井扩散段的倒椎体将流道分为上游部分和下游部分，竖井扩散段上下游两侧分别连接分流段，其中，进/出水口体型的设计结果由目标机组的工作参数、安装参数和地形参数确定的进/出水口体型的每个分段的设计尺寸和预设的至少一个连接约束得到每个分段的实际尺寸确定。本申请实施例可以通过结合侧式与竖井式进/出水口的水流特点，在有效改善尾水管后不均匀流态的同时兼具较好的地形适应性，进而满足紧接尾水管的低水头地面式厂房抽水蓄能电站进/出水口要求。
