基于舵机的双桶自动排水称重式遥测雨量计研制及在庄河地区的应用

Development of double barrel automatic drainage weighing telemetry rain gauge based on steering gear and its application in Zhuanghe area

庄河市是辽南地区降水量最为丰沛的县级市,暴雨频发、历时较短、强度大。目前,该地区共建有30处遥测雨量站,其中包含14处人工雨量站。遥测站雨量计均采用翻斗式雨量计,当强度较大的短历时暴雨发生时,翻斗灵活度降低,造成雨量数据丢失现象。本文设计发明了一款基于舵机的双桶自动排水称重式遥测雨量计,可以解决该地区短历时暴雨造成的翻斗式遥测雨量计误差较大的问题。

Zhuanghe is a county-level city with the most abundant rainfall in southern Liaoning Province.Rainstorms occur frequently,with short duration and high intensity.At present,there are 30 telemetric rainfall stations in the district,including 14 artificial rainfall stations.The rain gauges of remote measuring stations all adopt tipping bucket type rain gauges.When a short duration rainstorm with high intensity occurs,the flexibility of tipping bucket decreases,resulting in the loss of rainfall data.This paper designs and invents a double-barrel automatic drainage weighing telemetric rain gauge based on steering gear,which can solve the problem of large error of tipping bucket telemetric rain gauge caused by short duration rainstorm in this district.
