Portable artificial rainfall simulation device

Abstract

A portable artificial rainfall simulation device is composed of a water power device, a rainfall shower, a bracket, a quadrat device and a soil water monitoring device. The rainfall shower is fixed on the top of the bracket and is placed right over the quadrat device; the rainfall shower is connected to a pressure meter, a flowmeter, an artificial pressure pump and a bucket in the water power device through a water pipe of the water power device; a quadrat frame in the quadrat device is embedded into a soil quadrat; the quadrat frame has three closed faces, and one opening face in seamless integration with a collecting groove in the device; a rain cover completely covers the collecting groove; a counting cup is below a water outlet end of the collecting groove; a soil water sensor in the soil water monitoring device is connected with an HOBO collector in the device through a network port type socket; and the HOBO collector and a notebook computer are connected through an HOBO data line. The portable artificial rainfall simulation device has scientific design and simple structure, and enhances adaptability of the device in field, thus providing technical guarantee for conducting a large number of experiments and acquiring experimental data in the field.

Description

technical field [0001] The present invention is a portable artificial rainfall simulation device (abbreviated as CSRS) used in geography research, which is used for carrying out artificial simulation rainfall experiments in the field, and belongs to the technical field of natural geographic systems. Background technique [0002] The artificial rainfall simulation method is a scientific method that uses mechanical devices to simulate natural rainfall, conducts relevant scientific research and quickly obtains scientific research data. It has become an important technical means for indoor and field experiments. [0003] In the 1930s, the United States widely used the method of artificially simulated rainfall to study scientific issues such as soil infiltration, slope runoff, and soil erosion. my country also began to develop artificially simulated rainfall machines in the 1960s. It is divided into two types: nozzle type and needle tube type. In order to simulate natural rainfall...

Problems solved by technology

Liu Baoyuan and others carried out secondary development and improvement on the basis of the American trough rainfall machine, and did a lot of work to promote the development of artificial simulated rainfall machine in my country. However, due to the limitations of materials, power and water sources, the existing artificial The transportation and operation of the simulated rainfall device is relatively laborious, and the capital investment is large
