摘要: 为解决内河排水动力不足、建设用地困难等问题，结构紧凑、占地面积小的一体化闸门泵受到广泛关注，其中较大口径的一体化泵闸在国内应用时间较短、实例较少。以盐河泵闸工程为背景，采用三维参数化计算模型，进行门叶厚度、板厚度等参数设计优化分析，以及穿墙管、腹板薄弱处的加固分析；同时针对闸门泵振动、防腐等关键问题进行了分析论证。研究得出，门叶厚度不宜增加过大，应同时对区隔较大的面板、腹板结构进行适当加固，以控制共振频域；当闸门宽高比小于0.6且泵外径与闸门宽之比接近0.5时，宜采用12～16 mm范围内的板厚组合；穿墙管加固应横、纵、斜肋同时考虑；通过动态模拟分析，盐河泵闸设计能够避免一体化泵闸发生共振，且有一定的安全余量。Abstract: By solving the problems such as the shortage of drainage power in inland rivers and the difficulty of construction land, the integrated gate pump with compact structure and small floor area has received much attention. Among them, the integrated gate pump with larger diameter has a short application time and few examples in China. This paper takes the Salt River Pump Gate Project as the background, uses the three-dimensional parametric calculation model, carries on the design optimization analysis of the door blade thickness, the plate thickness and other parameters, and the reinforcement analysis of the weak parts of the wall pipe and web. At the same time, the key problems such as vibration and anticorrosion of the gate pump are analyzed and demonstrated. The results show that the thickness of the door blade should not increase too much, and the panel and web structure with large separation should be properly strengthened at the same time to control the resonance frequency domain. When the ratio of gate width to height is less than 0.6 and the ratio of the pump outer diameter to gate width is close to 0.5, the plate thickness combination in the range of 12～16 mm should be used. Transverse, longitudinal and diagonal ribs should be considered at the same time for wall pipe reinforcement. Through a dynamic simulation analysis, the design of Salt River Pump Gate can avoid the resonance of the integrated pump gate, and has a certain safety margin.
