[0002] In the field of environmental research experiments, it will be used to simulate rainfall devices. The existing sprinklers used in artificial rainfall devices, such as swing nozzles, will change the rainfall in each rainfall area during the swing process of the nozzles. The simulated rainfall is not realistic and cannot meet the requirements of the experiment. needs; in the Chinese patent ZL03156872.6, a simulated rainfall device is disclosed. The nozzles are arranged in parallel with each other in a plane, and each nozzle is equipped with a certain number of nozzles at a certain interval, and the same nozzle simultaneously simulates Heavy rain, moderate rain or light rain, under various rainfall conditions, the nozzle aperture of each nozzle is fixed, which cannot realistically reproduce the effect of natural rainfall, for example: in light rainfall, the aperture of the nozzle is relatively too large The raindrops are too large and uneven. When there is heavy rainfall, the aperture of the nozzle is relatively too small, which may cause insufficient rainfall, or the atomization effect of the rainfall cannot be controlled due to the high water pressure. It can be seen that in the prior art, The simulated rainfall device needs to be further improved to improve the realistic and natural effect of simulated rainfall
