As the most basic precipitation collection equipment in the field of hydrometeorology, the tipping bucket rain gauge has the characteristics of practicality and good stability, but there are some deficiencies in the research on the tipping characteristics and mechanism of the tipping bucket rain gauge and the causes of the mechanical error of the tipping bucket rain gauge. In this study, the mechanism of the tipping process of tipping bucket rain gauge was explored by means of combination of numerical simulation and indoor experiment with high-speed camera. The results show that during the turnover process, the time from start to stop is about 0.35-0.40 s, the time t1 from start to level is relatively high, about 80%-85%, and the time t2 from level to stop is only about 0.05 s, and there is a slight rebound after the turnover touches the adjusting nut. During t1 period, water will be continuously injected into the tipping bucket, which is the fundamental reason for the change of additional water volume and mechanical error of rain gauge with rain intensity. The tipping bucket will pour out the water in a very short time (about 0.4 s), and because the tipping bucket will cause slight rebound when touching the stop bolt, it will cause the "double peak" phenomenon of the tipping flow of the rain gauge tipping bucket when pouring out the water, and it will increase with the small installation inclination of the tipping bucket on the left and right. The research results can provide basic theoretical support for the improvement of tipping bucket rain gauge in the future.

翻斗式雨量计作为水文气象领域最为基础的降水采集设备,具有实用和稳定好等特点,但对翻斗翻转特性机理及翻斗式雨量计机械误差的产因的研究存在不足。为此,利用高速摄像机的室内试验和数值模拟相结合的方法从机理上探究了翻斗式雨量计翻斗的翻转过程。研究结果表明,翻斗在翻转过程中,从启动到停止的用时约为0.35~0.40 s,翻斗从启动到水平的耗时t1占比较高,约为80%~85%左右,从水平到停止t2仅约为0.05 s,且存在翻斗触及调节螺帽后的轻微回弹现象。在t1时间段内水会持续注入翻斗内,是造成附加水量及雨量计机械误差随雨强变化的根本原因。翻斗在极短时间内(约0.40 s)将水倾倒出,且由于翻斗在触碰停止螺栓时会造成轻微回弹现象,由此造成雨量计翻斗在翻出水时产生翻出流量的“双峰”现象,且随着翻斗左右安装倾角变小,而增大的现象。研究结果可为未来翻斗式雨量计的改进提供基础理论支撑。

翻斗式雨量计作为水文气象领域最为基础的降水采集设备,具有实用和稳定好等特点,但对翻斗翻转特性机理及翻斗式雨量计机械误差的产因的研究存在不足。为此,利用高速摄像机的室内试验和数值模拟相结合的方法从机理上探究了翻斗式雨量计翻斗的翻转过程。研究结果表明,翻斗在翻转过程中,从启动到停止的用时约为0.35~0.40 s,翻斗从启动到水平的耗时t1占比较高,约为80%~85%左右,从水平到停止t2仅约为0.05 s,且存在翻斗触及调节螺帽后的轻微回弹现象。在t1时间段内水会持续注入翻斗内,是造成附加水量及雨量计机械误差随雨强变化的根本原因。翻斗在极短时间内(约0.40 s)将水倾倒出,且由于翻斗在触碰停止螺栓时会造成轻微回弹现象,由此造成雨量计翻斗在翻出水时产生翻出流量的“双峰”现象,且随着翻斗左右安装倾角变小,而增大的现象。研究结果可为未来翻斗式雨量计的改进提供基础理论支撑。

As the most basic precipitation collection equipment in the field of hydrometeorology, the tipping bucket rain gauge has the characteristics of practicality and good stability, but there are some deficiencies in the research on the tipping characteristics and mechanism of the tipping bucket rain gauge and the causes of the mechanical error of the tipping bucket rain gauge. In this study, the mechanism of the tipping process of tipping bucket rain gauge was explored by means of combination of numerical simulation and indoor experiment with high-speed camera. The results show that during the turnover process, the time from start to stop is about 0.35-0.40 s, the time t1 from start to level is relatively high, about 80%-85%, and the time t2 from level to stop is only about 0.05 s, and there is a slight rebound after the turnover touches the adjusting nut. During t1 period, water will be continuously injected into the tipping bucket, which is the fundamental reason for the change of additional water volume and mechanical error of rain gauge with rain intensity. The tipping bucket will pour out the water in a very short time (about 0.4 s), and because the tipping bucket will cause slight rebound when touching the stop bolt, it will cause the "double peak" phenomenon of the tipping flow of the rain gauge tipping bucket when pouring out the water, and it will increase with the small installation inclination of the tipping bucket on the left and right. The research results can provide basic theoretical support for the improvement of tipping bucket rain gauge in the future.
