Abstract

The invention relates to a needle-type simulated rain device and a method for simulating rainfall thereof. The simulated rain device includes a rain device and a water supply device, wherein the rain device includes a frame, a transmission device and a rain collection box; the frame has two vertically connected frames; the transmission The device includes two identical sub-transmission systems fixed on the two frames; the rain collection box is a sealed cuboid, and two adjacent sides are connected to the two sub-transmission devices. The upper end of the rain collection box is equipped with a reactor, and the lower The end face is connected with a plurality of raindrop generators. The water supply unit includes a peristaltic pump. The present invention can fine-tune the size of raindrops, conveniently control the range of rain intensity and rainfall height, and is convenient to install and adjust the needle-type rainfall device indoors and outdoors, and is used for studying rainfall characteristic parameters such as raindrop diameter, rain intensity, raindrop terminal velocity, and raindrop kinetic energy.

Description

technical field [0001] The invention relates to a simulated rainfall device, in particular to a needle-type simulated rainfall device and a method for simulating rainfall. Background technique [0002] The artificial simulated rainfall device is one of the important facilities in the experiments related to the study of rainfall and rainfall effects. By changing the water supply pressure of the rainfall device, the water output, and the specifications of the raindrop generator, the rainfall parameters are directly or indirectly adjusted to complete a certain required rainfall process. simulation. At present, more and more indoor and field experiments are beginning to pay attention to the properties of raindrops, while most scientific research units mainly use sprinkler type (nozzle type) and pipe network type (spray type) rainfall devices with high cost, uneven rainfall, and small raindrops It is difficult to meet the accurate control of rainfall characteristics, and most of...
