The invention relates to a monthly accumulation sample collection device for atmospheric precipitation isotope analysis, which comprises a water collection funnel, a sample storage bottle, an aqueduct, a cover net, a pressure relief pipe and a floating ball. The funnel confluence port of the water collection funnel is installed on the upper part of the water guide pipe through the support, and the bottom of the water collection sleeve at the bottom of the storage bottle is in a closed state. The lower part of the water guide pipe is provided with an opening, and the water guide pipe and the water collecting sleeve are connected by threads. The upper part of the aqueduct is connected to the confluence port of the funnel, the lower part passes through the cap of the storage bottle and is connected to the water collection casing, and the floating ball is located at the inlet of the aqueduct at the confluence port of the funnel. The cap of the sample storage bottle is provided with a pressure relief hole pipe, the confluence port of the funnel is provided with an exhaust port, and the pressure relief hole pipe communicates with the exhaust port through a pressure relief pipe. The sampling process of the present invention does not require manual intervention, and the water sample evaporation in the sample collection process is effectively controlled by the small liquid surface exposure, the small inner diameter and long pressure relief tube blocking and the floating ball sealing, and the representativeness of the sample is guaranteed. The one-month sampling process does not require manual intervention and can save sampling costs.
Description
technical field [0001] The invention belongs to the technical field of measuring equipment, and relates to sampling equipment, in particular to a monthly accumulation sample collection device for isotope analysis of atmospheric precipitation. Background technique [0002] Atmospheric precipitation isotopes (D, 18 O and T) monitoring is a basic work of isotope hydrology research. Important isotope hydrology research projects often need to set up atmospheric precipitation isotope monitoring stations to understand the distribution of atmospheric precipitation isotope composition in specific regions. The International Atomic Energy Agency (IAEA) global atmospheric The precipitation monitoring network has been in operation for a long time. Atmospheric precipitation samples are collected using commercially available rain gauges, and evaporation (especially in arid regions) often occurs because the samples cannot be transferred in time, resulting in changes in the original isotope...
