AI Technical Summary

Technical Problem

Existing surface runoff and interflow collection devices lack stratified interflow filtration and collection devices, resulting in slow outflow of interflow, easy formation of supersaturated layers, and damage to the ecological environment after the devices are abandoned.

Method used

The system employs a soil interflow collection box, partition plate, surface runoff collection box, outlet, filter screen, and monitoring mechanism, combined with a lifting mechanism, cleaning mechanism, and height detection mechanism, to achieve effective collection and monitoring of stratified soil interflow, avoid the formation of supersaturated layers, and can be disassembled and reassembled to reduce environmental impact.

Benefits of technology

It effectively avoids slow outflow from the soil, ensures stable soil water levels, reduces the damage of the device to the ecological environment, improves the adaptability and collection efficiency of the device, and ensures monitoring accuracy and filter cleanliness.

Abstract

This invention discloses a monitoring device for collecting and monitoring surface runoff and stratified interflow on slopes, belonging to the field of soil and water conservation. It includes a base plate, with an interflow collection box mounted on top of the base plate. A partition plate is fixedly connected to the inner surface of the interflow collection box, and a surface runoff collection box is fixedly connected to its upper surface. Both the interflow and surface runoff collection boxes have outlets on one side, and filter screens are fixedly connected to the sides of both boxes adjacent to their outlets. This effectively prevents slow interflow, which could lead to a rise in soil water level and the formation of a supersaturated layer. After the experiment, the device can be disassembled for monitoring surface runoff and interflow at another location, effectively preventing the device from being abandoned and damaging grassland morphology, thus avoiding ecological impact. It also effectively prevents filter clogging, ensuring efficient surface runoff collection.
