超大量程雨量计在泄洪雾化测量中的应用

Application of Ultra Large Range Rain Gauge in Atomization Measurement of Flood Discharge

结合国家发明专利和一项实用新型专利,介绍一种用于测量泄洪雾化超高强度降雨的超大量程雨量计,其基本特征是承雨口面积小于储水容器水平截面面积。利用垂向雨量计和水平雨量计分别测量两个方向的降雨强度,达到测量最大斜向降雨的目的,并能准确获取降雨角度。该雨量计在两个工程应用中的实测成果充分证明,新型雨量计克服了传统雨量计难以测量超高强度降雨和斜向降雨的不足,能够为深入研究泄洪雾化的分布规律及影响范围提供更为完善的降雨参数。

Combined with the national invention patents,an ultra large range rain gauge is introduced to measure the flood discharge atomization of ultra-high intensity rainfall.Its basic feature is that the area of the rain port is smaller than the horizontal section area of the water storage container.The vertical rain gauge and the horizontal rain gauge are used to measure the rainfall intensity in two directions respectively,so as to achieve the purpose of measuring the maximum oblique rainfall and accurately obtaining the rainfall angle.The measurement results of rain gauge in two engineering applications are introduced respectively.The measurement results fully prove that the new rain gauge can overcome the shortcomings of the traditional rain gauge which is difficult to measure ultra-high intensity rainfall and oblique rainfall,and can provide more perfect rainfall parameters for further study of the distribution law and influence range of flood discharge atomization.
