Abstract

The invention discloses a pinhole anti-clogging artificial field simulated rainfall device, which is composed of an artificial rainfall device, a rain intensity test device and a lifting type raining device needle dredging device; the use of the lifting type raining device needle dredging device does not require each After the rain is over, the pinhole is pulled out and cleaned with an iron wire, which saves time and effort in the cleaning process of the needle, and at the same time ensures the permeability of the needle of the rain device, providing a stable rain intensity for the experiment. In addition, the use of the pin distribution plate at the bottom of the artificial rainfall tank divides the entire bottom plate into zero, and the entire row of needles can be quickly replaced by replacing the needle distribution plate with different specifications of needles, so as to quickly adjust the different rain intensities according to the experimental needs. Purpose, to simplify the process of needle replacement when adjusting the rain intensity. Therefore, the pinhole anti-clogging artificial field simulated rainfall device of the present invention has excellent rainfall experiment effect, and can be widely used in artificial field simulated rainfall.

Description

technical field [0001] The invention belongs to the technical field of soil property research equipment, and in particular relates to a pinhole anti-clogging artificial field simulated rainfall device. Background technique [0002] At present, a large number of experiments on soil erosion and solute migration are measured by indoor artificial rainfall in the artificial rainfall hall. Indoor artificial rainfall provided stable rain intensity and uniform raindrop strikes for the experiment, but most of the indoor research focused on simulating the impact of rainfall on disturbed soil, which was affected by human factors, and the measurement results were quite different from the actual situation in the field. Truly represent the actual situation in the wild. Therefore, at present, colleges and universities and scientific research units mostly use side spray simulated rainfall devices or pipe network (spray) to carry out simulation experiments in the field. The two methods of ...
