Abstract

The invention discloses a rainfall collection device for measuring rainfall hydrogen and oxygen isotopes through remote control and belongs to the field of rainfall collection. The rainfall collection device comprises a box body, wherein a collection assembly and a remote control device are arranged in the box body, and a temperature monitor and a wind speed monitor are arranged on the outer side of the box body; the collecting assembly comprises a collecting bottle and a funnel, and the collecting bottle is connected with the funnel through a guide pipe; the remote control device comprises a control circuit and a wireless communication circuit, an output end of the temperature monitor is connected with an input end of the control circuit, and an output end of the wind speed monitor is connected with an input end of the control circuit; and a wireless signal output or input end of the wireless communication circuit is connected with a wireless signal input or output end of the control circuit. The device is advantaged in that the temperature monitor and the wind speed monitor are used for testing the temperature and the wind speed in rainy days, then data are transmitted back to a user for measurement and calculation, the initial hydrogen and oxygen isotope content of a rainwater sample is reduced, and the measured hydrogen and oxygen isotope content is more accurate.

Description

technical field [0001] The invention relates to the field of rainfall collection, in particular to a rainfall collection device for remotely controlling and measuring rainfall hydrogen and oxygen isotopes. Background technique [0002] Stable isotopes in water molecules ( 16 O, 17 O, 18 O, 1 H, 2 H) and radioactivity ( 3 H) Isotopes are natural tracers of water bodies. During the natural water cycle, tritium and oxygen have become the most ideal environmental stable isotopes for tracing water cycles. Water from different water sources has different isotopic composition characteristics, so the source of the water cycle can be traced through changes in the hydrogen and oxygen isotopic composition of the water body. Atmospheric precipitation is an important link in the water cycle process, and its hydrogen and oxygen stable isotope composition is closely related to the natural environmental conditions of the water vapor source area, the climate conditions during the water...

Problems solved by technology

[0004] In order to overcome the defect existing in the prior art that when measuring rainfall hydrogen and oxygen isotopes, due to the fractionation of isotopes caused by the evaporation of rainwater, the concentration of hydrogen and oxygen isotopes changes to a certain extent, and finally it is impossible to accurately trace the source of the water cycle based on the measurement data of hydrogen and oxygen isotopes
