Automatic tracer agent feeding device for subsurface flow zone field tracing experiment and implementation method thereof

Abstract

The invention discloses an automatic tracer agent feeding device for a subsurface flow zone field tracing experiment. The automatic tracer agent feeding device comprises a remote control ship, whereina tracer agent storage induction system, a high-pressure micro-flow pumping system and a tracer agent feeding injection system which are connected in sequence are arranged in the remote control ship.The high-pressure micro-flow pumping system is connected with the tracer agent feeding injection system through a pipeline, and a shoreside distance measurement calibration system is arranged at thetail end of the remote control ship. The specific implementation method comprises the following steps: supplementing a tracer agent and a mixed solution thereof to the tracer agent storage system in advance; turning on the tracer agent storage switch, properly adjusting the telescopic initial length of the telescopic injection rod, turning on the high-pressure micro-flow pump and the high-pressuremicro-flow pump processor, then remotely controlling the boat to the set position on the shore, and releasing the tracer agent with the given concentration and dosage into the river subsurface flow zone. The tracer with certain concentration and dosage can be put into the river subsurface flow zone, and a research basis is provided for monitoring of a subsurface flow zone subsurface flow exchangefield tracing experiment.

Problems solved by technology

In the past, most scholars conducted research mainly through indoor circulating water tanks to simplify and simulate the subsurface flow exchange process under various conditions. Field tracer experiments encountered more difficulties due to limitations in manpower, financial resources, and material resources. However, field experiments are to test the theoretical feasibility. Therefore, when conducting field experiments, a fast, convenient, accurate, and adjustable tracer delivery device can be used, which will make the subsequent field tracer experiments in the subsurface zone and subsurface exchange process more effective.

[0003] At present, there are few domestic patents on the field observation tracer delivery device for subsurface flow exchange in the subsurface zone. In the past, field experiments were mostly restricted by realistic conditions, and it was necessary to frequently replace the tracer and its delivery device according to the requirements of the field tracer experiment, which increased the number of experiments. The cost of some injection devices is relatively complicated, and it is difficult to automatically control the concentration and dose of the injected tracer, and it is difficult to achieve the standards required by the experiment, resulting in large errors
