Description

technical field [0001] The invention relates to an adjustable artificial rainfall simulation device, which belongs to the technical field of artificial rainfall, and is especially suitable for the artificial simulation rainfall device for data collection of water and soil loss under different climate conditions in different regions. Background technique [0002] my country is one of the countries with the most serious soil erosion in the world. Soil erosion occurs all over the country, especially the loess in the northwest, the red soil in the south and the black soil in the northeast. Soil erosion endangers agricultural development, social stability, national security and sustainable social development, so it is of great significance to study soil erosion. [0003] Soil erosion can be classified into three types according to dynamics: hydraulic erosion, gravity erosion and wind erosion. For our country, there are many mountains, hills and slopes, and soil hydraulic erosion ...

[0004] At present, related patents related to artificial rainfall devices include: an experimental research device and method for rainfall regulation (20051002740.6) and an artificial rainfall simulation device (200910021960.5), which provide devices and methods for measuring soil erosion. Regulating experimental research device and experimental method (20051002740.6), although a simple structure and easy-to-use rainfall regulating experimental research device is provided, but the structure of the rainfall generating device in this device is simple, and the raindrop uniformity and rainfall intensity of simulated rainfall cannot be adjusted in real time , and can only be tested in the laboratory, the soil in the rain receiving device is collected outside the laboratory, which will cause a certain degree of damage to the original structure of the soil itself, and the experimental conclusion is not accurate enough

Although an artificial rainfall simulation device (200910021960.5) can adapt to a wide range of slopes, adjust the rainfall height, and adjust the size of the rainfall area, the device can only ensure the uniformity of rainfall and cannot perform real-time regulation of rainfall density. It can simulate natural rainfall under different climatic conditions in different regions, and the device structure cannot adjust the rainfall angle (such as the influence of wind on rainfall). It can only simulate natural rainfall in some areas with little wind, but cannot simulate natural rainfall in windy conditions. , poor applicability
