Embodiment Construction

[0014] 1. Structural design:

[0015] Referring to the accompanying drawings, the artificial simulated rainfall device of the present invention comprises a water supply support 1 and a rainfall device support 11, and the water supply support 1 is provided with a Marsh bottle water supply tank 5, and its principle adopts the Marsh bottle principle in physics, it It is possible to supply water to the rainfall device 12 under the condition that the water level of the rainfall device 12 is basically constant, so that the consistency of the high level of rain intensity is guaranteed. A water level pressure sensor 3 (Shaanxi Xi'an Ansen Intelligent Instrument Co., Ltd.: ACS-L digital liquid level sensor), there is a ventilation pipe above the water supply tank of the Martens bottle, and the bottom of the ventilation pipe is located on the "rain intensity-water level calibration line", and there is a ventilation pipe above the water supply tank 5 of the Martens bottle. The bottom of ...

Abstract

The invention discloses an artificially-simulated rainfall device which comprises a water supply bracket and a rainfall bracket, wherein the water supply bracket is provided with a Marten bottle water supply box; a vent pipe is arranged above the Marten bottle water supply box, and the bottom of the Marten bottle water supply box is provided with a pressure sensor; a breathing pipe is also arranged above the Marten bottle water supply box, and the bottom of the breathing pipe is positioned on a raininess-water level calibration line; the pressure sensor is connected with an upper computer outside the Marten bottle water supply box for measuring and recording the raininess in real time through a communication line in the breathing pipe; and both sides of the Marten bottle water supply box are provided with a water inlet pipeline and a water outlet pipeline, wherein the water inlet pipeline is used for supplying water for the Marten bottle water supply box, and the water outlet pipeline is used for supplying the water for a sprinkler which is arranged on a sprinkler bracket through a connecting piece. The artificially-simulated rainfall device can adapt to gradients within a larger range, adjust the rainfall height, adjust the size of a rainfall sub-district and more truly simulate natural rainfall.

Description

technical field [0001] The patent of the present invention relates to a rainfall device, especially an artificial simulated rainfall device, which can be used on slopes, adopts the principle of a Martens bottle, can ensure the uniformity of rain intensity with high precision, and can record rain intensity in real time. Background technique [0002] Soil erosion, nutrient change, soil water change, soil permeability, etc. are the important contents of soil and water conservation research, experiment and monitoring in my country. At present, the observation of the above indicators is mainly the impact of runoff, sediment, nutrients and Conduct observations of pollutants, etc., and then scientifically analyze the observation data to explore the internal laws behind the surface natural phenomena. [0003] However, purely relying on natural rainfall to collect the required scientific research data has great limitations. Experience shows that it generally takes 15 to 25 years to o...
