Example Embodiment

[0019] The device for establishing an indoor soil and water conservation model proposed by the present invention has the following structure: image 3 As shown, it includes a rain shower 11 , a awning 14 , an underlying surface model 15 , a sampler 19 and a runoff bucket 16 . The rain shower 11 is placed on the top of the bracket 13 , the rain shelter 14 is placed in the middle of the bracket 13 , and the underlying surface model 15 is placed at the bottom of the bracket 13 . The rainfall device 11 is composed of a main pipe 26 and a branch pipe 27, the main pipe is square, a plurality of branch pipes are arranged in parallel in the main pipe, and the main pipe and the branch pipes are connected with each other. One side of the main pipe 26 is provided with a water inlet pipe 12, and the opposite side is provided with a sewage pipe 25. The underlying surface model 15 includes a slope surface 20, a side wall, a movable side clapboard 21 and a movable rear clapboard 23. The slo...

Abstract

In the invention, rainfall unit, canopy and low step face model are position at upper, middle and lower parts of bracket. Rainfall unit includes main pipe connected to water inlet pipe and branch pipes, and discharge pipe is in side opposite to the main pipe. Low step face model includes slope face, sidewall, movable lateral clapboard and movable back clapboard. Four sidewalls in model are sidewall, front wall, movable lateral clapboard and movable back clapboard. The invention includes sampler, curb and runoff bucket are arranged at proper position. Main pipe and branch pipes are made from PVC. Raininess is even. The invented equipment is suitable to indoor model test for larger area. The equipment is easy to be installed.

Description

technical field [0001] The invention relates to a device for establishing an indoor water and soil conservation model, which belongs to the technical field of agricultural water conservancy. Background technique [0002] figure 1 It is an existing indoor soil and water conservation test device. In the figure 1 is the rainfall simulator, and 2 is the underlying surface model. See "The effect of soil air entrapment on soil erosion during simulated rainfall, Transactions of the ASAE, 1985, Volume 28 , pp. 1598-1601. The disadvantage of this rainfall device is that the effective spraying area is very small, and it is impossible to complete a large-scale rainfall simulation model test. As shown in the figure, the projected area of ​​the underlying surface model is only 0.67m×0.4m. [0003] In the indoor scale model test, the rainfall factor can only be solved by artificial simulation. At present, the rainfall simulators used in soil and water conservation tests are divided into...
