Detailed description of the Preferred Embodiments

With reference to figs. 1-4, the embodiment of the present

invention provides a technical scheme: the artificial rainfall device

can be easily carried and operated when studying the infiltration and

runoff of alpine meadow soil, and can ensure the normal and accurate

experiment, at the same time, it also solves a series of problems caused

by excessive pressure of the existing device, and the water consumption

is greatly reduced, the device is cleaned more quickly and conveniently,

and is not easy to be blocked. The artificial rainfall device comprises

a sleeve 1, a water tank 2, a coiled plastic pipe 3 and a

Tipping-bucket-type self-metering rain gauge 4. The sleeve l can easily

enter hard soil under the action of the pedal 18, meanwhile, the

needle-like head of the insert block 19 is designed to have stronger

grip, and the height of the supporting mechanism can be adjusted

arbitrarily by the adjusting knob 20, which is more stable and simple

than the device lying on the ground. One side of the top of the water

tank 2 is provided with a water injection port 21, and the inside of

the water injection port 21 is movably connected with a piston 22. The

front of the water tank 2 is fixedly connected with an observation

window 23. The observation window 23 can observe the water capacity

inside the water tank 2, which is convenient for subsequent water

filling. The bottom of the water tank 2 is fixedly connected with a

protective plate 24, the bottom of the surface of the sleeve 1 is fixedly

connected with a foot pedal 18, and the bottom of the foot pedal 18

is fixedly connected with an insert block 19. The tops on both sides of the surface of the sleeve 1 are movably connected with adjusting knobs 20, the surface of the coiled plastic pipe 3 is fixedly connected with a round leveling bubble 17, and the inside of the sleeve 1 is movably connected with a telescopic support rod 5. The other end of the coiled plastic pipe 3 is communicated with a water outlet pipe 15 through a water outlet pipe interface 14, and the end of the water outlet pipe 15 far away from the coiled plastic pipe 3 is communicated with one side of the water tank 2 through a water tank interface 16. A water outlet valve 25 is fixedly connected inside the water outlet pipe 15, which can prevent the rainfall device from being damaged due to excessive pressure and has many controllable elements. When the device is cleaned again, the water outlet pipe 15 and the water tank interface

16 are disconnected. The magnetic pump 7 and water inlet valve 11 are

opened for flushing, which is more convenient and quick and saves water

resources. The top end of the telescopic support rod 5 penetrates

through the sleeve 1 and extends to the top end of the sleeve 1. The

top of the surface of the telescopic support rod 5 is fixedly connected

with an annular buckle 6. The surface of the coiled plastic pipe 3 is

fixedly connected with the surface of the annular buckle 6. A water

outlet of the magnetic pump 7 is communicated with a water inlet pipe

9, and the diameter of the water inlet pipe 9 is larger than that of

the water outlet pipe 15, so that the water flow can quickly fill the

rainfall device, and a certain pressure can be ensured to ensure that

the conical orifice 13 can normally discharge water; the cooperation

of the water inlet valve 11 and the water outlet valve 25 enables the rainfall intensity to be well controlled; and one end of the water inlet pipe 9 far away from the magnetic pump 7 penetrates through the water tank 2 and extends to the top of the water tank 2. One end of the water inlet pipe 9 extending to the top of the water tank 2 is communicated with one end of the coiled plastic pipe 3 through a water inlet pipe interface 10, the inside of the water inlet pipe 9 is fixedly connected with a water inlet valve 11, one side of the top of the surface of the water inlet pipe 9 is fixedly connected with a precision flowmeter 12, and the bottom of the coiled plastic pipe 3 is provided with tapered holes 13. The coiled plastic pipe with tapered holes 13 adopts the idea of "dropper technology", and a large number of practical experiments ensure that each tapered hole 13 can smoothly discharge water.

When in use, after selecting an appropriate experimental site, the four

telescopic support rods 5 and the coiled plastic pipe 3 are connected

by four ring buckles 6, and the sleeve 1 is fixed in a specific

experimental place by a foot pedal 18. Observe whether the bubble of

the round level bubble 17 is in the middle. If it is, the device is

leveled. If it is not, it is necessary to turn the adjusting knob 20

to adjust the height of the supporting mechanism so that the rainfall

device is in a horizontal position. Open the piston 22 on the water

tank 2, deliver the water to the inside of the water tank 2 through

the water inlet 21, and open the water inlet valve 11 and the precision

flowmeter 12. At the same time, the water outlet valve 25 is opened,

and the water in the water tank 1 is transported into the spiral plastic

pipe 3 through the pumping pipe 8, the water inlet pipe 9 and the water inlet pipe interface 10 with the maximum lift of the magnetic pump 7, so that the whole rainfall device can be filled. If the effect is not very good, the opening and closing of the water outlet valve 25 can be controlled (in a half-open state), so that the full effect of the rainfall device is better, because the rainfall device adopts the spiral plastic pipe 3 structure, which will make the whole process faster. Then adjust the opening of outlet valve 25, observe the degrees of precision flowmeter 12 with different openings, record the rainfall intensity corresponding to Tipping-bucket-type self-metering rain gauge 4, count the relationship between flow and rain intensity, draw a flow and rain intensity curve, observe the degrees on precision flowmeter 12 when adjusting the different openings of outlet valve 25, and find out the corresponding rain intensity. In this process, when the degree of precision flowmeter 12 is stable, the corresponding rain intensity is the real rain intensity. At the same time, the stopwatch starts to time, which is used as reference data for the rainfall calculated in the subsequent experiment. After the experiment is finished, for the second application of the device, the magnetic pump

7 is turned off, and each device is separated. The connecting part

between the water inlet pipe 9 and the water outlet pipe 15 is blocked

with a rubber plug to prevent the small debris outside from entering

the device and causing the blockage of the conical hole 13 at the lower

end of the coiled plastic pipe 3. All other parts can be collected and

assembled, thus completing the whole work.

The embodiment discloses an artificial rainfall device, which comprises a sleeve, a water tank, a coiled plastic pipe and a

Tipping-bucket-type self-metering rain gauge, wherein a telescopic

support rod is movably connected inside the sleeve; the top end of the

telescopic support rod penetrates through the sleeve and extends to

the top end of the sleeve; an annular buckle is fixedly connected at

the top of the telescopic support rod surface. When studying the

infiltration and runoff yield of alpine meadow soil, the device can

be easily carried and operated, and the normal and accurate experiment

can be ensured. At the same time, a series of problems caused by

excessive pressure of the existing device are solved, and the water

consumption is greatly reduced, and the device is cleaned more quickly

and conveniently, which is not easy to block.
