The utility model relates to a simple rain gauge specially designed for micro-precipitation, in particular to a simple rain gauge specially designed for micro-precipitation which can monitor sporadic micro-precipitation. The utility model comprises a rainwater collector, a metering tube and an outer barrel, which is characterized in that the rainwater collector is an inverted triangular cone with openings at both ends, and is provided with an upper opening and a lower opening. The diameter of the upper opening is equal to or greater than the diameter of the outer barrel, and the upper opening is supported on the upper edge of the outer barrel; the metering tube is a cylinder with an upper opening and a closed lower end. The upper opening of the metering tube is connected with the lower opening of the rainwater collector, and the side wall of the metering tube is marked with a scale and corresponding rainfall value. The utility model has the positive effect of being able to monitor sporadic micro-precipitation, reducing measurement error, improving accuracy, simple structure and convenient use.
【技术实现步骤摘要】
微降水量专用简易雨量器
本技术涉及一种雨量器,特别涉及一种能够监测到零星微小降水量的微降水量专用简易雨量器。
技术介绍
如图1所示,现有的普通雨量器包括储水瓶21、储水筒22、漏斗23、量杯24等,雨水通过储水筒22的筒口先落入漏斗23内,然后再由漏斗23集中收集在储水瓶21内,最后将储水瓶1内的雨水倒入量杯24内进行测量。由于雨水需要经过漏斗23、储水瓶21、量杯24等多个容器,雨水在流动、转移等过程中,会有少量雨水附在漏斗23、储水瓶21上,造成最终的雨水测量结果存在误差。当测量零星微小降水量时,测量误差会更大。因此,现有的普通雨量器很难监测到零星微小降水量。
