Simulated rainfall device and its rainfall method

Abstract

The invention discloses a rainfall simulating device and a rainfall method thereof and relates to the technical field of artificial rainfall. The rainfall simulating device comprises a water delivery pipe which is arranged in a rectangular shape, a plurality of pinheads which are directionally arranged, a pressure regulating tank, a water supply tank, a first water guide pipe, a second water guide pipe, a piston I and a piston II, wherein the pinheads are vertically arranged on the water delivery pipe upwards; a water outlet and a water supply port which are positioned on the same horizontal plane are formed at the bottom of the pressure regulating tank; a water injection port is formed on the top of the pressure regulating tank; a valve is arranged on the water outlet; one end of the first water guide pipe is arranged on the water supply port of the pressure regulating tank and the other end of the first water guide pipe is positioned at the bottom inside the water supply tank; one end of the second water guide pipe is arranged on the water outlet and the other end of the second water guide pipe is connected with the water delivery pipe; a horizontal plane at the bottom of the water supply tank is higher than a horizontal plane on the top of the pressure regulating tank; an air guide pipe is arranged on the piston II; and the lower end of the air guide pipe, the water outlet and the water supply port are positioned on the same horizontal plane. Power is not needed, low-intensity rainfall can be simulated, and the rainfall intensity is stable.

Description

technical field [0001] The invention relates to the technical field of artificial rainfall, in particular to a simulated rainfall device and a rainfall method used in the research and application of rainwater utilization technology. Background technique [0002] In the 21st century, human beings will face serious water shortages. Making full use of rainwater resources is one of the important ways to solve the problem of water shortage. The simulated rainfall device is a device that must be used in the research and application of rainwater utilization technology. At present, most artificial rainfall simulation devices require electric water pumps to supply water, but in actual field experiments, they are often troubled by the difficulty of power supply. Moreover, due to the high water pressure of the water supply, it is difficult to form a small rainfall intensity. The intensity of simulated rainfall using an electric water pump often needs to exceed 20mm / h to be relatively...

Problems solved by technology

Although some artificial rainfall simulation devices do not use electric water pumps to supply water, the intensity of simulated rainfall is unstable due to insufficient water supply pressure
