AI Technical Summary

Technical Problem

Existing hydraulic model devices cannot avoid the influence of water flow in the pool when measuring the intensity of splashing mist rain generated by the collision of water tongue and downstream water cushion, resulting in insufficient measurement accuracy.

Method used

A measuring device comprising a rectangular water trough and a rainfall intensity collection unit was designed. The device moves within the water trough by suspension to avoid collision with the water jets. A support rod and guide rail structure is used to ensure stability and measurement accuracy. A rain-blocking mechanism is combined to reduce errors. A specific calculation method is used to measure the spatial distribution of rainfall intensity.

Benefits of technology

It enables accurate measurement of the intensity of splash atomized rain, reduces the impact of water flow on the measuring device, and improves the accuracy and stability of the measurement.

Abstract

The application discloses a measuring device and method for splash atomization rainfall intensity spatial distribution in a hydraulic model. The measuring device comprises a rectangular water tank and a rainfall intensity collecting unit. The rainfall intensity collecting unit is composed of a horizontally arranged support panel and a plurality of rainfall collectors vertically arranged on the support panel. All the rainfall collectors are arranged in a matrix form. The rainfall intensity collecting unit is suspended in the water tank through a support moving unit and can move in space in the water tank, so as to realize the measurement of the splash atomization rainfall intensity spatial distribution. The water tank is provided with a water outlet on the side wall away from the water tongue and the water cushion collision area. The measuring device can be used for measuring the splash atomization rainfall intensity spatial distribution of the jet flow into the water in the hydraulic model and has high accuracy.
