Novel slope runoff and interflow velocity measurement tracer release instrument

Abstract

The invention relates to a novel slope runoff and interflow velocity measurement tracer release instrument, which comprises a base, a main supporting rod, a tracer barrel sleeve, a tracer barrel, a tracer bag, a tracer bag connection rod, a tracer bag connection rod frame, a handheld rotation rod terminal sliding and rotating shaft sliding shaft frame, a tracer connection rod frame general connection rod and a handheld rotation rod, wherein the tracer barrel is arranged in the tracer barrel sleeve; the upper part of the main supporting rod is provided with the handheld rotation rod terminal sliding and rotating shaft sliding shaft frame; and a handheld rotation rod starting-end rotation shaft sleeve is arranged in a handheld rotation rod terminal sliding and rotating shaft sliding groove of the handheld rotation rod terminal sliding and rotating shaft sliding shaft frame, and the handheld rotation rod sliding and rotating shaft is adopted for movable connection. The novel slope runoffand interflow velocity measurement tracer release instrument has the beneficial effects that one-time hand-control connection rod operation is achieved, five branch tracer bag connection rods can release the tracer smoothly and flexibly at the same time, and transverse and uniform release of the tracer at the upper end of a slope runoff test plot is ensured.

Description

technical field [0001] The patent of the invention belongs to the technical field of slope hydrodynamics and soil hydrodynamics research, and specifically relates to a new type of tracer dosing instrument for measuring the flow velocity of slope runoff and soil flow. Background technique [0002] In the runoff monitoring test of slope surface runoff, because the slope runoff water layer is thin, the runoff velocity cannot be measured by conventional methods (such as flow meter), and the tracer method is a relatively effective and convenient method for measuring slope runoff velocity. method. When the tracer method is used to measure the flow velocity of slope runoff, the injection of the tracer is mostly realized by manual injection, and this can only be done at one point, which only measures the local flow velocity and cannot reflect the slope of the entire runoff area. The average velocity of surface runoff. If the width of the test runoff plot is relatively wide, it is ...

Problems solved by technology

Then we processed the instrument device according to the drawings, and put it into scientific research experiments. After a period of use and testing, we found that the sliding head at the connection between the hand-held rotating rod and the main connecting rod of the tracer connecting rod frame often The phenomenon of jamming occurs, which is not convenient for the simultaneous release of tracers in a short period of time, which affects the experimental effect and experimental accuracy
