Bidirectional flow channel pump station and working mode and simulation method thereof
The invention discloses a two-way flow channel pump station and a working mode and a simulation method thereof. The two-way flow channel pump station comprises a channel water tank, a field water tank, three sets of UPVC hard pipes, a set of hoses, a water suction pump, a first valve, a second valve, a third valve, a fourth valve and a fifth valve. Different opening and closing combination modes of the first valve, the second valve, the third valve, the fourth valve and the fifth valve are matched with the working state of the water suction pump, and the four working conditions of self-flowing irrigation, self-flowing drainage, pumping pressure irrigation and pumping pressure drainage are achieved. The method also comprises the following steps: acquiring a three-dimensional model of the bidirectional flow channel pump station system, carrying out grid division on the three-dimensional model, carrying out simulation calculation in combination with initial conditions and boundary conditions to obtain data of a plurality of working conditions, comparing experimental data, carrying out coefficient correction on a fitting curve, and finally obtaining a plurality of working conditions. The problem that the water level is difficult to accurately control according to the real-time water demand of crop growth in the irrigation and drainage process is effectively solved.
本发明公开了一种双向流道泵站及其工作模式和模拟方法，包括渠道水箱、田间水箱、三组UPVC硬管、一组软管、抽水泵、以及一号阀门、二号阀门、三号阀门、四号阀门、五号阀门。本发明将一、二、三、四、五号阀门不同的开闭组合方式配合抽水泵的工作状态，实现自流灌溉、自流排涝、泵压灌溉、泵压排涝四种工况。本发明还通过获取双向流道泵站系统的三维模型，对所述三维模型进行网格划分，结合初始条件和边界条件模拟计算获得多个工况的数据，对比实验数据，对拟合曲线进行系数修正，有效解决了灌排过程中难以根据作物生长实时需水量精确控制水位的难题。
