Outdoor rainwater metering mechanism

Abstract

The invention relates to the field of metering devices, in particular to an outdoor rainwater metering mechanism. The outdoor rainwater metering mechanism comprises a box body, a rainwater collectingdevice and a metering device, wherein the metering device is located below the rainwater collecting device, a regulating pipeline for connecting the metering device and the rainwater collecting deviceis arranged between the metering device and the rainwater collecting device, a regulator is arranged in the regulating pipeline, a placing gap is opened on the box body, the rainwater collecting device is located in a mounting gap and matched with the box body in a lapping state, a water outlet pipeline is arranged below the metering device, and the rainwater collecting device comprises a rain collector, a barrier part and a cleaning component, wherein a connecting part is fixed by the rain collector and the regulating pipeline. The outdoor rainwater metering mechanism disclosed by the invention has the beneficial effects that a water inlet plate can be sealed through a sealing cover while not raining to prevent dirt from entering the metering device, and a first detector and a second detector in a housing detect rainwater in a water overflow tank in real time, and when one of a first detection component or a second detection component is damaged, the other detection component still can detect the rainwater.

Description

technical field [0001] The meter and field of the present invention are specifically an outdoor rainwater metering mechanism. Background technique [0002] With the acceleration of urbanization, the increase of the proportion of urban impervious surface, the increase and advance of the urban rainfall peak, the problem of urban waterlogging has become prominent and intensified, and the problem of urban safety has been challenged unprecedentedly. To solve the problem of urban waterlogging, in addition to To optimize the urban drainage network system, it is also necessary to have enough real-time rainfall data to take necessary defensive measures. How to obtain certain real-time rainfall data has become an important research field in the field of urban waterlogging disaster warning. [0003] The application number is CN201320097242.8, which discloses a multifunctional siphon rain gauge, including a cylinder body, a bracket, a water holder, a funnel, a meter, a siphon tube, a wa...
