Description

Technical Field

[0001] This utility model belongs to the field of simulated rainfall, and in particular relates to an oscillating artificial rainfall simulation device. Background Technology

[0002] Artificial rainfall simulation is not limited by time and space, and can analyze data and information in a short time to shorten the research cycle. It can also simulate different rainfall environments by designing and strictly controlling experimental conditions.

[0003] Currently developed artificial rainfall simulators mainly include needle-type, side-spray, and downspray types. Needle-type artificial rainfall simulators can meet the needs of both indoor and outdoor artificial rainfall simulation. However, the raindrops generated by the needles lack initial velocity, and due to the height limitation of the simulator, the raindrops generally struggle to reach their final velocity, resulting in raindrop energy far lower than natural rainfall. Simultaneously, the effective rainfall area is also limited by the size of the needle matrix. Therefore, needle-type artificial rainfall simulators are generally only used to simulate small-scale, low-intensity rainfall, often for research on raindrop splashing and infiltration processes. Side-spray artificial rainfall simulators have a simple structure, low cost, and are convenient to install, disassemble, transport, and maintain. However, when used in the field, raindrops are highly susceptible to wind during their descent, requiring specialized windbreaks. The effective rainfall area of ​​a single side-spray nozzle is not rectangular, and the combined use of multiple side-spray nozzles increases the difficulty of equipment debugging and rainfall intensity calibration. This type of simulator also consumes a large amount of water, limiting its widespread use in the field. Downspray artificial rainmaking devices allow raindrops to reach their terminal velocity without requiring a high descent altitude, making them less affected by wind during outdoor use. However, raindrops produced using a single type of downspray nozzle suffer from issues such as uniform size distribution, excessive atomization, and low energy. Combining multiple downspray nozzle types is technically complex, and equipment debugging and rainfall intensity calibration are difficult. Therefore, downspray artificial rainmaking devices are less effective at simulating raindrop distribution and energy compared to sidespray devices. Furthermore, like sidespray devices, downspray devices consume a significant amount of water, limiting their use in the field. In research on artificial rainmaking devices, different types have simulated the characteristics of natural rainfall to some extent, but due to the inherent limitations of different raindrop formation mechanisms, they cannot perfectly replicate the characteristics of natural rainfall.

[0004] Among various artificial rainfall simulation devices, the oscillating artificial rainfall simulation device has advantages such as simple structure, stable rainfall, good controllability, convenient disassembly and installation, low water consumption, and good field applicability. The oscillating artificial rainfall simulation device mainly obtains different rainfall intensities by changing the oscillation frequency of the nozzle, while the nozzle model and water supply pressure remain basically unchanged. This results in the raindrop size, raindrop distribution, and raindrop velocity of different intensities having little or no variability, which is significantly different from natural rainfall.
