Abstract

The invention discloses a method and a device for artificial simulated rain and atomization. The device comprises a dual-purpose water-gas nozzle, a high-pressure gas guide pipe, an air compressor and a frequency converter, wherein a water inlet of the dual-purpose water-gas nozzle is connected to a water supplying end of a rainfall pipeline, a gas inlet of the dual-purpose water-gas nozzle is connected to one end of the high-pressure gas guide pipe, the other end of the high-pressure gas guide pipe is connected to the air compressor, and the air compressor is connected to the frequency converter. During light rain or heavy rain, the air compressor is opened, the air with the pressure is mixed with the rainfall through the dual-purpose water-gas nozzle, the rainfall is jetted through high-pressure gas, the preset spraying angle and atomization effect are achieved, and the defect of a prior artificial rainfall device is avoided. Besides, the frequency converter is adjusted, the output air pressure of the air compressor is adjusted in accordance with the strength of rain, and the optimized effect is achieved. The device is simple to operate, convenient to use and good in practical value.

Description

technical field [0001] The invention relates to an artificial rainfall system for indoor landslide model experiments, in particular to a method and device for artificially simulating rainfall atomization. Background technique [0002] In the existing artificial rainfall system, the atomization of rainfall mainly depends on the atomization of the pipeline rainwater hitting the spiral rotating nozzle. This atomization method is the most common atomization method in the artificial simulated rainfall system at present. The rainwater with a certain pressure in the pipeline system hits the spiral rotating nozzle to achieve the atomization at the preset dispersion angle. [0003] However, this atomization method has disadvantages in use. In the case of artificial rainfall systems that need to complete light rain and heavy rainfall, especially when the simulated slope is damaged by light rain and strong erosion for a long time, the use effect cannot be achieved in this case. The ma...

Problems solved by technology

[0004] The present invention aims at the existing artificial rainfall system. In the case of light rain and heavy rainfall, the rainwater flowing through the injection pipeline will be very little, and the pressure in the tube cavity will decrease accordingly. The original 120-degree injection angle of the nozzle may be only To 100 degrees, the preset rainfall coverage area cannot be reached, and the problem of uniform atomization is accompanied by concentrated raindrops. A method and device for artificially simulating rainfall atomization are proposed to achieve rainfall in the case of strong light rain. Method and device still able to achieve spray nozzle design spray angle and rainfall atomization
