Slope surface runoff field runoff samplers

Abstract

Each slope surface runoff field runoff sampler is composed of a sampling bottle system, a floating ball system, a floating ball bouncing system and a water guide groove (5); the sampling bottle systemincludes a sampling bottle (1), a sliding groove (6) and a water guide groove fixed ring (12); the floating ball system includes a floating ball (2), a positioning rod (3) and a floating ball handle(4); the floating ball bouncing system includes a counterweight (7), a dialing rod (8), a lifting rope (9), a dialing ring (10) and the water guide groove (5). When earth surface runoff is produced, the runoff first enters the sampling bottle (1) of a first sampler, when a water level (13) of the sampling bottle (1) rises to a certain height, the floating ball (2) rises, and at the same time, oneend of the water guide groove (5) is lifted up, so the water guide groove is inclined to the reverse direction, a first water storage bottle finishes sampling; the runoff enters sampling bottles of anumber of samplers along the inclined water guide grooves and is sequentially sampled. The samplers are simple in structure and simple to operate, and are the slope surface runoff field runoff samplers which can be used for respectively, equally, continuously and automatically collecting runoff samples in the one-time runoff process at different atmospheric rainfall intensities and in different earth surface runoff intensity periods.

Description

Technical field: [0001] The patent of the present invention relates to a runoff sampler used in conjunction with the slope runoff field. This slope runoff sampler has the function of automatically sampling in stages, and can divide the surface runoff generated in the slope runoff field during a precipitation process into equal parts. It can be used to analyze and study the law of soil erosion, and at the same time determine the surface diameter Flow rate, soil erosion volume and erosion modulus. technical background: [0002] Soil erosion is an important sign of environmental degradation, which is highly concerned by ecologists and all walks of life. There are many methods for studying soil erosion, but the slope runoff field method is often used for long-term positioning research on soil erosion. At present, my country has established a series of slope runoff fields at different site types in the forest ecological positioning observation and research station, soil and wat...

Problems solved by technology

However, at present, the slope runoff field is not equipped with multifunctional monitoring equipment. It simply collects and measures the runoff and its total sediment content generated during each precipitation process to determine the surface runoff, soil erosion and The erosion modulus makes it impossible to study the law of soil erosion in depth, such as the accurate and rapid determination of the relationship between soil erosion intensity and rainfall intensity, surface runoff intensity, ground slope, soil structure, vegetation coverage and other natural elements
