Multifunctional water and soil loss tester

Abstract

The invention relates to a multifunctional water and soil loss tester, and belongs to the technical field of environment-friendly equipment. The multifunctional water and soil loss tester comprises anadjustable high liquid pump, a disk type spray device, an erosion groove, a rotating body and a motor, wherein the disk type spray device is connected with the adjustable high liquid pump through a pipeline; the rotating body is arranged at the bottom of the erosion groove; the motor drives the rotating body to drive the erosion groove to rotate at a uniform speed; the disk type spray device comprises a disk body and extension tubes which are respectively communicated with a plurality of spray heads located on the front surface of the disk body; the erosion groove comprises a bottom, a firstside surface, a second side surface, a third side surface, a first wing part, a second wing part and a third wing part; the first, second and third side surfaces are seamlessly connected with the bottom; and the first, second and third wing parts are seamlessly connected with the first, second and third side surfaces. The multifunctional water and soil loss tester has the advantages of being simple in structure, convenient, practical, stable in performance and uniform in water spray, and is capable of adjusting rainfall capacities and testing the influences, on water and soil loss, of rainwater under different rainfall capacities, different gradients and different runoffs.

Description

technical field [0001] The invention relates to a multifunctional soil erosion measuring instrument, which belongs to the technical field of environmental protection equipment. Background technique [0002] Guizhou Province is located in the southwest of my country, with an annual rainfall of up to 1264.4 mm, a warm and humid climate, and a pleasant climate. There are tens of thousands of vascular plants and more than a thousand vertebrates. However, Guizhou Province is facing severe environmental problems. Rocky desertification is the largest and most concentrated area in the world, and it is one of the areas with the most typical karst development and the most abundant and complex landscape types. The land area of ​​more than mild rocky desertification in Guizhou has reached 35 920 km2, accounting for about 20.39% of the total land area of ​​the province. Among them, 14 counties and cities have more than 30% of the land rocky desertification area, and 8 counties and cities...

AI Technical Summary

Problems solved by technology

In order to study the impact of rainwater on soil in karst rocky desertification areas, a variety of soil erosion measurement devices have been specially developed, but the existing soil erosion measurement devices are relatively complicated in structure, not uniform in spraying water, poor in stability, and not strong in practicability. Measuring the impact of different amounts of rainwater on soil erosion does not achieve the purpose of taking effective preventive measures to prevent soil erosion; and there is no device that can adjust rainfall, measure the impact of different rainfall, different slopes, and different runoff water on soil erosion. influences
