Abstract

The invention relates to a leaching liquid metering device which comprises a water collecting device, a bucket-tipping rain gauge, a transparent graduated tube and a data acquisition device, wherein a water outlet I is arranged on one side at the bottom of the water collecting device; a three-way valve is connected to the water outlet I; the bucket-tipping rain gauge is positioned below a leaching liquid outlet; a water outlet II is arranged at the bottom end of the bucket-tipping rain gauge, mounted at the top end of the water collecting device, and communicated with the water collecting device; the transparent graduated tube is vertically arranged, and connected with the second connector of the three-way valve; the data acquisition device is connected with the bucket-tipping rain gauge through a signal line. Through combination of the bucket-tipping rain gauge and the water collection device, not only can the leaching liquid occurrence time, frequency and strength be recorded in real time by connecting the data acquisition device and the bucket-tipping rain gauge, but also the total leaching liquid flow can be accurately metered when the flow rate is relatively high, that is, the leaching liquid metering device can be utilized for accurately measuring the leaching liquid occurrence time, frequency and strength and the total leaching liquid flow caused by every rainfall or every irrigation.

Description

technical field [0001] The invention relates to a leachate metering device, which belongs to the field of research facilities. Background technique [0002] When conducting research on plant irrigation, soil water infiltration, and water and fertilizer management, it is necessary to monitor and record the leaching time and amount of soil leachate in real time. At present, the method of metering after all the liquid is recovered is mostly used in the research in this area. The cost of the traditional method is relatively low, but the recovery fluid needs to be measured regularly, and the recovery fluid is the total amount within a period of time, which cannot accurately reflect the occurrence time, frequency and intensity of the leaching fluid within a certain period of time. [0003] The occurrence time and intensity of soil leachate are closely related to the time and intensity of rainfall or irrigation, there is uncertainty in time, and the flow is unstable.
