TECHNICAL FIELD
[0001] The utility model relates to the field of rainfall collection, especially to be used for the collection device of rainfall isotope water of many fields. BACKGROUND
[0002] In the field of monitoring and research of natural environment, as an important part of water cycle, the characteristic analysis of precipitation has vital significance for understanding climate change, water resource management, ecological system balance and agricultural irrigation. The proportion of hydrogen and oxygen isotopes and other chemical components (such as ion concentration, dissolved gas, etc.) in precipitation are key indicators for assessing water source, precipitation process, cloud physical properties and atmospheric pollution status. Therefore, accurately and efficiently collecting and preserving rainfall water samples for subsequent detailed chemical and isotopic analysis has become an indispensable part of meteorology, hydrology and environmental science research.
[0003] The traditional rainfall water sample collection method is mostly manually operated, that is, when rainfall occurs, researchers or automatic weather station staff manually collect water samples and immediately mark and store them. However, this method has obvious limitations when facing continuous rainfall in multiple fields: first, it is difficult to ensure that the water samples of each rainfall are not mixed by subsequent rainfall, resulting in decreased data accuracy; second, manual operation is inefficient, especially in remote areas or harsh weather conditions, making it difficult to achieve continuous and uninterrupted sampling; third, the preservation conditions of water samples after collection are difficult to control uniformly, such as temperature fluctuations that may cause changes in chemical components in water samples, affecting the accuracy of analysis results; fourth, there is a lack of effective sealing measures, water samples are easily in contact with external air, introducing pollution or causing water sample evaporation, further affecting analysis quality.
[0004] In view of the above problems, it is particularly important to have a function of automatically, continuously and efficiently collecting and preserving rainfall water samples in multiple fields. It can effectively distinguish and individually collect each field of rainfall, avoid mixing of water samples and low-temperature preservation, and ensure the independence and accuracy of data.

[0043] The driving mechanism 8 controlled by the controller 2 is connected between the water storage barrel 10 and the water collecting funnel 3, and is used to drive the water collecting funnel 3 to rotate above the outer barrel 14.

The sampling barrel 13 is a circular arc type water barrel, and a handle is arranged at the top of the sampling barrel 13 to facilitate lifting. The inner circle of the sampling barrel 13 is provided with a water inlet hole and a water guide groove. After the rainwater enters the sampling barrel 13 through the water inlet hole, the outlet of the water collecting funnel 3 at the lower end is turned to the water guide groove of the sampling barrel 13. At this time, the rotation of the lower end of the water collecting funnel 3 will drive the sealing ring 11 to block the water inlet hole of the sampling barrel 13.

After the upper end of the funnel is closed to complete the sampling of the sampling barrel 13, the controller 2 controls the driving mechanism 8, so that the water collecting funnel 3 rotates by a certain angle, so as to adjust the water guide pipe 31 at the lower end of the water collecting funnel 3 to the water guide groove 132, and the excess rainwater is discharged or the ultra-pure water is flushed.
[0055] Preferably, the hot air machine 7 connected with the controller 2 is further included, the air outlet of the hot air machine 7 communicates with the inside of the water collecting funnel 3, and the hot air outlet of the hot air machine enters the inner wall of the funnel obliquely downward. Prevent the problem that the water flows into the hot air machine 7 during the rain and the cleaning. And at the lower end of the funnel, prevent the impurities from being blown into the water sample during the hot air drying process. After the rainwater flows from the water collecting funnel 3, the water guide pipe 31 and then the sampling barrel, the ultra-pure water flushes the water collecting funnel 3 to collect the rainwater next time. After the ultra-pure water is used for washing, the controller 2 controls the hot air machine 7 to dry the moisture on the inner wall of the water collecting funnel 3 by hot air, so as to ensure that the rainwater is collected next time without being doped.
[0056] Preferably, the photovoltaic panel 1 is further included to provide energy for the collecting device.

A plurality of positioning buckles 102 are welded in the inner ring of the water barrel at the same horizontal plane, so that the sealing ring 11 can rotate in the annular positioning buckle. It can be guaranteed that the water after flushing can flow out through the passage at the bottom of the combination, and finally flow out of the device through the water outlet at the bottom of the outer barrel 14, so as to ensure that there is no water residue in the device. The radial outer side of the bottom of the outer barrel 14 can be a slope to facilitate the concentration of water flow.
[0058] Further, the water storage barrel 10 supplies water to the spraying device through the water pump 9.
[0059] The connection scheme of the water storage barrel 10 and the water collecting funnel is that the water pump 9 draws the quantitative ultra-pure water in the water storage barrel 10 into the spraying device of the water collecting funnel 3 through a water pipe. After the water collecting funnel 3 is closed to complete the conveying work of rainwater, the water collecting funnel 3 is rotated to the water guide groove in the inner circle of the sampling barrel 13-1 by a certain angle, at the same time, the lower end of the water collecting funnel 3 drives the sealing ring to rotate, and then the water inlet hole of the sampling barrel 13-1 is blocked. Then the controller 2 controls the water pump 9 to draw the quantitative ultra-pure water in the water storage barrel 10 into the flushing plate 6 of the water collecting funnel 3, so as to flush the last rainfall residue or dust in the funnel, and the sewage flows into the water guide groove in the inner circle of 13-1 through the lower end of the water collecting funnel, and finally flows out through the water outlet at the bottom of the outer barrel 14. After being flushed, the hot air machine 7 blows hot air to dry the residual water in the inner wall of the funnel for a period of time.

The sampling device has a low-temperature preservation function, so as to slow down the biochemical reaction rate of the water sample, prolong the preservation time, and reduce the chemical composition change caused by temperature change and the isotope value fluctuation caused by water evaporation.
[0062] The device uses solar energy as an energy source, and the electric energy is stored and output through the controller 2. When connected, the bottom center of the outer barrel 14 is raised and fixed, so that the water outlet at the bottom can be exposed to facilitate water discharge.
