Abstract

The invention discloses a field artificial rainfall simulator comprising a water tank. The water tank is fixed to the ground by means of a leveling support. Plate levels are arranged at the top of the water tank. Needles for simulating rainfall are arranged at the bottom of the water tank. The water tank is connected to a magnetic pump arranged in a water storage tank by means of a water inlet pipe. The magnetic pump is used for injecting a solution in the water storage tank into the water tank. The solution in the water tank flows into the water storage tank via an overflow water outlet pipe which is movably mounted on a water level adjusting support. According to the field artificial rainfall simulator and an application method thereof provided in the invention, a water level-rainfall intensity relation curve only needs to be measured once, and one water level corresponds to one rainfall intensity, thereby avoiding the problem of measuring the rainfall intensities before every experiment. The height of the overflow water outlet pipe is adjusted to control the water level in the water tank, thereby control the rain intensity, and then continuously varying rainfall intensities can be obtained without repeatedly changing needles. In addition, local evaporation capacity can be roughly obtained. The field artificial rainfall simulator is applicable to complex terrains in field, and the method is simple, and easy to operate, high in working efficiency, showing a broad application prospect.

Description

technical field [0001] The invention relates to the technical field of artificial rainfall, in particular to a field artificial rainfall simulation device and an application method thereof. Background technique [0002] The study of soil properties is of great significance in the fields of hydrology, farmland water conservancy, water and soil conservation, hydrogeology, and ecological environment. Soil infiltration experiments are an important means of studying soil properties. Relying solely on natural rainfall to collect the required scientific research The data are very limited, so in order to simulate the natural infiltration as much as possible, it is necessary to approximate the natural rainfall in the field. [0003] Most of the current rainfall simulation devices use the method of replacing the needle to control the intensity of the rain. After each replacement of the needle, it is necessary to measure whether the rain intensity meets the requirements. Otherwise, it ...
