Embodiment
The preferred implementation of lightweight Auto Core γ scanning instrument of the present invention is described in detail below in conjunction with accompanying drawing.
Composition graphs 1 and Fig. 2 show the embodiment of lightweight Auto Core γ scanning instrument of the present invention: this lightweight Auto Core γ scanning instrument, comprise radiation detector 3, it is characterized in that: described lightweight Auto Core γ scanning instrument comprises a square scanner casing 1, four driving wheels 2 are provided with below scanner casing 1, scanner casing 1 inside is provided with radiation detector 3 from front to back successively, control circuit and accumulator 4, motor and drive unit 5, motor and drive unit 5 are connected with four driving wheels 2, scanner casing 1 upper surface front portion is provided with switch 6 and USB flash disk and power interface 7, scanner casing 1 upper surface middle part is provided with liquid crystal interface and keyboard 8, scanner casing 1 upper surface rear portion is provided with mini-printer 9, control circuit in control circuit and accumulator 4 comprises amplifying circuit, microprocessor, printer interface, LCD interface, accumulator in control circuit and accumulator 4 is 24V lithium battery, control circuit and accumulator 4 are respectively by data line and liquid crystal interface and keyboard 8, mini-printer 9 connects, liquid crystal display in liquid crystal interface and keyboard 8 is the rectangle liquid crystal panel of 128mm × 64mm, motor in motor and drive unit 5 is 86 serial stepper motors.
Composition graphs 1 and Fig. 2, the detection principle of core γ scanning instrument and upper computer software surface chart are as Fig. 2.After the sweep span of scanner and sampling time are set, on core 10, the gamma-rays that radiomaterial on measurement point in core 10 radiates is collected by radiation detector 3, the effects such as NaI (T1) crystal in the ray collected and detector ionizes, excite, are finally absorbed and are converted to voltage pulse signal through subsequent conditioning circuit and exported.General γ photon correspondence exports a voltage pulse signal, therefore the gamma intensity that core 10 is released is directly proportional to the voltage pulse signal of output.Simultaneously, in core 10 to be measured, the content of contained radioactive nuclide determines gamma-ray intensity size, and the characteristic of rock itself determines the number of radioactive nuclide in core 10, therefore measure the kind that number of pulses in this voltage pulse signal unit interval and Gamma irradiation dose rate just tentatively can judge core, and then distinguish the lithology of core 10.
Microprocessor mainly carries out acquisition and processing to the pulse signal exported, and demonstrate corresponding counting rate in a liquid crystal display, and all supplemental characteristics of institute's measuring point will automatic storage among USB flash disk, user can print the corresponding natural gamma curve of core 10 at any time.Measurement data file among USB flash disk also can read with upper computer software under Windows operating environment, facilitates user to observe the curve of scan-data intuitively, and can revise initial core 10 degree of depth and unit correction factor.
Above is only the preferred embodiment of the present invention, and it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
