Embodiment 1

[0032] This embodiment provides a device suitable for uniform flow distribution, with a cylindrical design, which is a cylindrical shape widely used in China.

[0033] See attached figure 2 As shown, the device is composed of a flow diversion device 1, a diversion pipe 2, a diversion pipe 3, an emptying valve 4 and a collecting tank 5, and the bottom of the diversion device 1 is connected with the emptying valve 4, wherein the diversion pipe 2 will The runoff is transported to the geometric center of the diversion device 1, and several diversion pipes 3 are evenly arranged around the diversion device 1. All the diversion pipes 3 must have the same tube length and be on the same level. The collecting pool 5 and one of the diversion pipes 3 catch.

[0034] The diameter of the cylinder is 0.9m, and the height is 0.8m. Nine shunt pipes of Φ38mm are evenly distributed around the shunt device.

[0035] 1. Implementation verification test of "central inflow"

[0036] The water an...

Abstract

The invention discloses a uniform shunting method applied to water and soil conservation monitoring, and an apparatus thereof. Radial flow enters from the geometric center of the shunting apparatus, and the water flow direction is vertical to the bottom surface of the shunting apparatus, so an inflow point has a same distance to every shunting tube; and the length of all the shunting tubes is same, so a flow collecting tube and the shunting tubes are arranged in a same manner. The method and the apparatus reach a uniform shunting effect to effectively guarantee that a water sand sample collected by a flow collecting barrel (pool) fully represents the composition of shunted water sand, so the test precision of radial flow in a runoff plot is improved, and accurate and reliable water and soil loss data can be obtained.

Description

technical field [0001] The invention relates to the technical field of soil and water conservation monitoring, and more particularly relates to a method and device for uniform flow distribution applicable to soil and water conservation monitoring. Background technique [0002] my country is facing a serious problem of soil erosion. Soil and water conservation monitoring is the basis for quantitative research on soil and water loss. Runoff plot method is usually used to obtain experimental data to forecast and estimate regional soil erosion and sediment production. Although the automatic observation of soil and water loss in my country has progressed rapidly in recent years, it is affected by field conditions of soil and water monitoring, such as power supply, background light, water temperature, sediment particle size, chemical composition of sediment, and sedimentation. The measurement accuracy of observation techniques is constrained. At present, most of the runoff and se...
