A remote control rainfall collection device for measuring rainfall hydrogen and oxygen isotopes

Abstract

The invention discloses a rainfall collection device for remotely controlling and measuring rainfall hydrogen and oxygen isotopes, belonging to the field of rainfall collection, including a box body, a collection component and a remote control device are arranged inside the box body, and a temperature monitor and a wind speed monitor are arranged outside the box body instrument; the collection component includes a collection bottle and a funnel, and the collection bottle and the funnel are connected through a conduit; the remote control device includes a control circuit and a wireless communication circuit, the output of the temperature monitor is connected to the input of the control circuit, and the output of the anemometer is connected to the control circuit. The circuit input terminal is connected; the wireless signal output or input terminal of the wireless communication circuit is connected with the wireless signal input or output terminal of the control circuit. The beneficial effects of the present invention are: the temperature monitor and the wind speed monitor are used to test the temperature and wind speed of the weather when it rains, and then the data is sent back to the user for calculation, and the initial hydrogen and oxygen isotope content of the rainwater sample is restored to determine the The 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...

AI Technical Summary

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
