The sprayer is arranged on the bracket through transmitting channel. The device controls the valve to act. The invention uses pump to press, and transmits them to each sprayer through water converter, controls the open quantity, size and spraying time of sprayers through the control device, it can realize real simulation to the natural rain, it has characters of small error, automatic control, wireless remote control.

Description

technical field [0001] The invention relates to a rainfall simulation device used in a laboratory. Background technique [0002] When people study the geological soil layer, especially when conducting landslide tests, they need to choose a place that meets the requirements outdoors for on-site demonstration according to the research object. First, the geological soil layer is explored to confirm its geological structure and soil composition. Choose an appropriate slope to erect a large-scale sprinkler device that simulates natural rainfall. Although such a simulation study can faithfully reflect the impact of rainfall on the soil layer and obtain real research data, the research process is too lengthy and requires a lot of work. Manpower, material resources, and repeated experiments cannot be carried out at the same place, so people hope to conduct simulation experiments by establishing various soil layer models simulating natural structures indoors to overcome the shortcomi...

[0002] When people study the geological soil layer, especially when conducting landslide tests, they need to choose a place that meets the requirements outdoors for on-site demonstration according to the research object. First, the geological soil layer is explored to confirm its geological structure and soil composition. Choose an appropriate slope to erect a large-scale sprinkler device that simulates natural rainfall. Although such a simulation study can faithfully reflect the impact of rainfall on the soil layer and obtain real research data, the research process is too lengthy and requires a lot of work. Manpower, material resources, and repeated experiments cannot be carried out at the same place, so people hope to carry out simulation experiments by establishing various soil layer models simulating natural structures indoors to overcome the shortcomings of outdoor field demonstrations, but this poses a challenge to the rainfall simulation system. However, the key simulation parameters such as water spraying volume, water spraying position, and atomization degree of general rain shower devices are not easy to operate and control, and it is impossible to achieve random and uniform distribution of rainfall areas, which is different from actual rainfall conditions. There is a big difference, which cannot meet the needs of the experiment
