Abstract

The invention discloses a three-dimensional integrated water and soil loss demonstration apparatus, and belongs to the field of experimental devices. The three-dimensional integrated water and soil loss demonstration apparatus is used for demonstrating water and soil loss and comprises an adjusting frame. Adjusting rods which can move in the up-down directions and can be fixed are mounted on the adjusting frame, adjusting plates are mounted on a side of the adjusting frame and are connected with accommodating plates by adjusting bolts and adjusting holes, and test boxes are arranged on the accommodating plates; water pipe fixing blocks are mounted on the adjusting rods, water pipes are mounted on the water pipe fixing blocks, spray nozzles are mounted at the tail ends of the water pipes, the heads of the water pipes are positioned inside water tanks, and water pumps are mounted on the water pipes and are connected with battery packs by wires. According to the technical scheme, the three-dimensional integrated water and soil loss demonstration apparatus has the advantages that comparison tests can be carried out on water and soil loss phenomena by the aid of set variable contrast modes, accordingly, water and soil loss knowledge can be visually acquired by students, and the ecological environmental protection awareness can be improved.

Description

technical field [0001] The invention belongs to the field of experimental devices, and in particular relates to a three-dimensional integrated water and soil loss demonstrator for classroom demonstration of water and soil loss phenomena. Background technique [0002] Excessive vegetation reclamation will easily lead to the reduction of soil vegetation coverage. And the reduction of soil cover vegetation can easily lead to the loss of soil when it is washed by rainwater. However, in the existing classroom teaching process, most of the students acquire the knowledge of soil erosion through textbook pictures or teaching videos, and cannot personally experience the phenomena and consequences of soil erosion through field inspections. [0003] How to achieve the teaching of soil and water loss through experiments, so that students can obtain knowledge of the causes of soil and water loss, the phenomenon of water and soil loss, water seepage contrast, stratum formation and water ...
