A 0.5mm double amount of tipping bucket rainfall sensor, a cylindrical Yuqi Sheng, is at the bottom of the base tube shaped base in Yuqi Sheng, Sheng in the Yuqi followed from a lower water collector, big bucket, upper water collector, small bucket, funnel, each water collector is arranged in the vertical the board, in the funnel above the anti blocking device. The small bucket design into a symmetrical slope container, the lower the big bucket design into the labyrinth shaped container, to skip around room center of symmetry, swinging balance, stability in strong storm impact, the measuring accuracy of the sensor is high. The utility model has the advantages of good water flushing property, high surface hardness and environmental protection safety. The error is not affected by the magnitude of rain intensity, and the instantaneous rainfall can be measured. The rain sensor is ensured to work stably and the measurement data is accurate. Easy access to faulty components during maintenance, easy to remove and replace these faulty components, reduce manufacturing and site maintenance costs.
【技术实现步骤摘要】
本技术属于气象观测装置,特别涉及一种0. 5mm感量双翻斗式雨量传感器。
技术介绍
当前国内外生产的雨量传感器主要有翻斗式、虹吸式、称重式、双阀容式、双筒互溢式等。其中的翻斗式雨量传感器由于其性能稳定,测量降雨量不受限制,可靠性强,维修性好,制造成本低,测量误差符合气象观测要求,输出信号便于采集和处理等特点被普遍应用。但在工作实践与比较研究中,我们发现国内外现有的翻斗式雨量传感器还存在某些不足。例如德国Thies公司生产的单翻斗式雨量传感器,由于结构设计的问题,从承水器汇集下来的不同雨强的雨水注入计量翻斗时,另其两个斗室在进行转换的间隔时间内, 进入斗室的失水量随雨强大小的不同而不同,导致翻斗计量误差的波动性很大,使其技术指标达不到国标《翻斗式雨量计》的技术要求。澳大利亚NEA公司生产的虹吸翻斗式雨量传感器为了解决上述在不同雨强条件下翻斗的计量误差,在其雨量传感器的承雨筒出口处安装了一个虹吸装置,以使从承雨筒汇集下来的雨水先流进虹吸管,再以恒定的雨强注入计量翻斗,然而该设计虽然解决了不同雨强条件下翻斗的计量误差,却又出现了虹吸渗漏问题,该渗漏在大小雨强时均可发 ...
