Accurate irrigation metering device
The invention discloses an accurate irrigation metering device. The accurate irrigation metering device comprises a first irrigation canal, wherein the first irrigation canal communicates with a metering mechanism and a second irrigation canal respectively; the metering mechanism comprises two metering water tanks which are arranged in parallel; each metering water tank is provided with a water inlet valve and a water outlet valve; the water outlet valves are communicated with a third irrigation canal; the third irrigation canal communicates with the second irrigation canal; and liquid level sensors are mounted at the tops and the bottoms of the metering water tanks respectively. By adopting the accurate irrigation metering device, the disadvantages in the prior art can be improved and accurate metering of irrigation water is realized.
本发明公开了一种精确灌溉计量装置，包括第一灌溉渠，第一灌溉渠分别与计量机构和第二灌溉渠连通，计量机构包括并联设置的两个计量水池，计量水池上安装有进水阀门和出水阀门，出水阀门与第三灌溉渠连通，第三灌溉渠与第二灌溉渠连通，计量水池顶部和底部分别安装有液位传感器。本发明能够改进现有技术的不足，实现灌溉用水的精确计量。
