Continuous sampling and measuring device for runoff sediment in water and soil conservation monitoring plot

Abstract

The invention discloses a continuous sampling and measuring device for runoff and sediment in a water and soil conservation monitoring plot, relates to the technical field of environmental monitoring,and solves the problems that most of measuring devices used at present are used for continuous collection, cannot directly intercept part of water flow for water sample collection and are not accurate enough in measured data. A continuous sampling and measuring device for runoff sediment in the water and soil conservation monitoring plot comprises a canal body. A sample storage plate is fixedly arranged in the front side of the top of the canal body through bolts; a diversion channel is fixedly arranged at the top of the sample storage plate through a fixing cylinder; a floating box is slidably arranged on the bottom surface of the top of the front side of the canal body; by arranging the floating box, a closed cut-off and collection function is provided for the measuring device, the floating box is of a channel structure, after the two sides of the floating box are synchronously closed through a flashboard, runoff can be cut off and collected, it is guaranteed that the sampling stateis kept uniform, and the sampling accuracy degree is improved.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a continuous sampling and measuring device for runoff sediment in a water and soil conservation monitoring area. Background technique [0002] The flow of rainfall and snowmelt water flowing along the surface or underground under the action of gravity is called runoff. According to the source of water flow, there are rainfall runoff and meltwater runoff; according to the flow mode, it can be divided into surface runoff and underground runoff, and surface runoff can be divided into slope flow and channel flow; in addition, there are solid substances (sediment) in the water flow. Runoff, ion runoff composed of chemically dissolved substances in the water flow, etc. [0003] After searching, for example, the patent No. CN208751909U discloses a continuous sampling and measuring device for soil and water conservation monitoring runoff and sediment, including a U-shap...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a continuous sampling and measuring device for soil and water conservation monitoring area runoff sediment, to solve the problem that the currently used measuring devices proposed in the above-mentioned background technology are mostly Continuous collection, cannot directly intercept part of the water flow for water sample collection, the measurement data is not accurate enough, does not have the power structure for automatic auxiliary collection, does not have the structure for evenly dispersing samples, and is not conducive to the problem of constant collection
