Description

Technical Field

[0001] The present application relates to the technical field of simulated rainfall, and in particular to an artificial rainfall simulation device. Background Art

[0002] When conducting rainfall research, due to the lack of runoff observation points in some areas, it is difficult to obtain long series of rainfall data with a large time span. Experimental studies of rainfall and runoff under natural conditions have the disadvantages of being significantly affected by environmental climate, making it difficult to artificially control experimental conditions and requiring a long research period. Furthermore, if runoff monitoring is conducted directly on the surface under natural conditions, the many unpredictable and uncontrollable factors on the natural surface will lead to large data errors. In addition, natural surface runoff data is difficult to collect and the required research period is relatively long, which is not convenient for later statistical analysis of the data. Therefore, there is an urgent need to provide an artificial simulation device. Utility Model Content

The real-time pipeline pressure and rainfall volume collected by the rain gauge and pressure sensor can be used to adjust the water pump power and opening and closing degree to control the rainfall intensity and duration, thereby adjusting according to experimental requirements. The control system receives and stores the data, facilitating subsequent statistical analysis. The artificial rainfall simulation device of this application can manually control conditions, shorten the research cycle, control factors, reduce errors, and facilitate rainfall research.
