Intelligent device for measuring seepage velocity of groundwater

Abstract

An intelligent device for measuring the seepage velocity of groundwater comprises a probe and an intelligent terminal device, wherein, the probe comprises a measurement / control component, a source-releasing device and a communication interface; the measurement / control component comprises NaI crystal, a photomultiplier and a control circuit; the photomultiplier, the source-releasing device and the communication interface are connected with the control circuit respectively; the probe is connected with a Bluetooth wireless communication device via the communication interface; the Bluetooth wireless communication device is connected with the intelligent terminal device on a Bluetooth communication basis. The intelligent device of the invention has the advantages of high measurement accuracy and high operating efficiency and greatly reduces the consumption of radioactive sources, thereby not only effectively protecting the environment, but also reducing the injury to human bodies caused by rays; the overall design of the probe reduces the number of the interfaces and effectively guarantees the safe and stable operation of the devices in well-logging; according to the design, the sources of the source-releasing device are symmetrically released, thereby achieving the purpose of uniform source-releasing; and Bluetooth-based wireless control and portable devices are adopted, thereby simplifying the devices and facilitating the field operation.

Description

technical field [0001] The invention belongs to the technical field of groundwater dynamics measurement, and relates to a groundwater seepage velocity measurement device. Background technique [0002] For the measurement of groundwater seepage flow rate, the measurement method is to put radioactive sources in the well logging, record the ray intensity through the ray sensing element, measure the radioactive source intensity in the well logging at different times, and use the radioactive source intensity in the well logging at different times and The point dilution theorem is used to obtain the groundwater seepage velocity. In the prior art, a osmometric system based on a Geiger tube as a sensing element is commonly used. The Geiger tube is made according to the ionization effect of rays on gas. The usual structure is to use a metal wire as the cathode in a closed glass tube, and use a metal cover as the anode at the other end of the glass tube. The glass tube is filled with...
