A tracer dosing instrument for measuring slope runoff and soil flow velocity

Abstract

The invention relates to a tracer dispensing instrument for measuring the flow velocity of slope runoff and soil flow, comprising a base, on which a main supporting rod is arranged, and a hand-held rotating rod rotating shaft is arranged on the upper support frame of the main supporting rod, The rotating shaft of the hand-held rotating rod is connected to the front end of the rotating rod through the rotating shaft, and an initial state locking bolt is arranged on the upper end of the main support rod, and the initial state locking bolt cooperates with the initial state lock hole on the fixed hand-held rotating rod Position limit, the hand-held rotating rod is provided with an upper and lower groove on the hand-held rotating rod to connect the total connecting rod of the tracer connecting rod frame, and the total connecting rod of the tracer connecting rod frame is limited by the fixed shaft collar of the total connecting rod. Position, the fixed shaft collar of the total connecting rod is arranged in the middle of the main support rod; the present invention measures the flow velocity in the soil by using the tracing method of groundwater flow velocity measurement, and the instrument of the invention can be used for the measurement of slope runoff velocity. The tracer delivery can also be used to measure the tracer delivery at different levels of soil flow velocity.

Description

technical field [0001] The patent of the invention belongs to the research technical field of slope hydrodynamics and soil hydrodynamics, and specifically relates to a device for injecting a tracer 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 necessa...
