Abstract
A plane source calibrating device of a nuclear detecting instrument comprises the components of: a base board (1), a slide rod (2), a plane source board (3), a screw handle (4), a slide block (5), a left slide board (6), a screw (7), a right slide board (8) and a hand wheel (9), wherein the plane source board (3) is placed above the slide block (5). The screw handle (4) is connected with a screw hole in the slide block (5) through the screw whereon. The plane source board (3) on the slide block (5) can be lifted vertically along with rotation of the screw handle (4), thereby conveniently adjusting a height distance H between the plane source board and a sensing surface at the lower surface of the detecting instrument. The height distance H can be accurately determined through a scale line next to a fixing bracket of the slide block (5), thereby quickly calibrating the nuclear instrument. The plane source calibrating device can automatically adjust the height distance H between the nuclear detecting instrument and the plane source. Furthermore high convenience and high speed in calibrating are realized.
Description
Technical field
The invention belongs to core detecting instrument metering field, be specifically related to a kind of Nuclear Power Station detecting instrument plane source calibrating installation.
Background technology
Before general kernel detecting instrument uses, need to be to nuclear instrument, for example data parameters, sensing range, sensitivity are calibrated, and allow instrument reach the standard that user needs.And such calibration just needs radioactive source, such as plane source (general closed planar source size is 170 × 120mm) is proofreaied and correct.
First by the holding plane of face source, the core detecting instrument then need being used, perpendicular to face source side to and close.Different height distance H, the detected data of instrument are just different.
According to user's environment for use, with the difference of user demand, the needed sensitivity of core detecting instrument, sensing range are just different.
Finally, according to instrument request for utilization, set height distance H, revise sensing range, the sensitivity etc. of nuclear instrument, make it to reach user's needs.
General core detecting instrument plane source calibrating installation at present, the face source plate in holding plane source, all cannot automatically adjust the height distance H between the sensitive surface below face source plate and core detecting instrument, only have and constantly change face source plate thickness, reach the adjusting of height distance H, such device heaviness and complex operation, the precision of calibration is not high.
Summary of the invention
Object of the present invention is exactly the deficiency in order to overcome above-mentioned background technology, and a kind of core detecting instrument plane source calibrating installation is provided, and this device can regulate the height distance H between core detecting instrument and plane source automatically, and calibrates convenient and swift.
A kind of core detecting instrument plane source calibrating installation involved in the present invention, comprise base plate 1, slide bar 2, face source plate 3, screw rod handle 4, slide block 5, left skateboard 6, screw rod 7, right slide plate 8, handwheel 9, wherein, face source plate 3 is placed on above slide block 5, screw rod handle 4 is connected with the threaded hole in slide block 5 by the screw rod on it, face source plate 3 on slide block 5 can be with the rotation oscilaltion of screw rod handle 4, height distance H between sensitive surface below adjusting range source plate and core detecting instrument easily, the scale mark on the fixed support side by slide block 5 can be determined height distance H accurately, thereby quickly nuclear instrument is calibrated.
A kind of core detecting instrument plane source calibrating installation of the present invention, can automatically regulate the height distance H between core detecting instrument and plane source, and calibrate convenient and swift.
