Background technique

China's water resource problem is very prominent, water resources are short, the total amount accounts for only 6% of the world, and water resources are unevenly distributed in time and space, and the matching degree of water and land resources is low. Generally speaking, my country's water resource problems have a direct impact on food security. impacts, that is, water resources and food security are an issue of reciprocal causation. As rainwater is the key way to replenish water resources, the distribution of rainfall, the amount and time of rainfall are all very important, so it is necessary to study the relevant laws of rainwater.

At present, the research on rainwater often focuses on the division of regional climate types, rain detection and urban planning and many other aspects. In agriculture, the role of rainwater is self-evident. Rainwater is used to replenish surface water, groundwater, etc., to meet the growth of crops. Rain gauges are often used to collect rainwater-related data. The traditional rain gauge consists of two parts, including a measuring cup and a funnel. In the case of actual rainwater collection, affected by light, temperature, and airflow fluctuations, some rainwater will evaporate from the hole below the funnel, resulting in loss of rainwater, inaccurate rainfall, and fractionation of stable isotopes of hydrogen and oxygen in rainwater. At the same time, due to the simple structure of the traditional rain gauge, it needs to be collected every day during the rainy period. For regions like Hainan with a long rainy season and frequent rainfall, it requires a lot of manpower and material resources. Therefore, the collected rainwater is only suitable for situations where the accuracy of rainwater is not high. For understanding the series of movements of rainwater after it falls to the surface, such as understanding the water migration in the agricultural forestry complex system, the depth of crops absorbing water, and soil evaporation And crop transpiration and other related studies are not accurate enough. For this reason, it is very necessary to develop a kind of automatic rainwater collector that can solve the above problems.
