Referring to fig. 1, a calibration device for a surface contamination monitor according to some embodiments of the present utility model is provided, where the surface contamination monitor is provided with a standard planar source, and the surface contamination monitor may be an α, β surface contamination monitor. The surface pollution monitor calibrating device comprises a connecting rod 1, a rotary table 2 which is rotationally connected with the connecting rod 1 and used for accommodating a standard plane source, and a storage disc 3 which is connected with the connecting rod 1 and can do lifting motion along the axial direction of the connecting rod 1, wherein a plurality of accommodating grooves 21 for accommodating the standard plane source are formed in the rotary table 2, and the surface pollution monitor is arranged on the storage disc 3.
It will be appreciated that calibration of the surface contamination monitor is typically performed by placing the meter to be calibrated above a standard planar source, typically 5mm or 10mm, and then recording and processing the readings of the surface contamination monitor, ultimately producing the original recording and calibration certificate. In the utility model, the accommodating groove 21 is arranged on the turntable 2 for accommodating a standard plane source, and the standard plane source is fixed in the accommodating groove 21, so that the stability and the accuracy of the position of the standard plane source are ensured. In addition, the object placing disc 3 is used for placing a surface pollution monitor to be calibrated, the object placing disc 3 is located above the rotating disc 2, and can be lifted to different heights along the axial direction of the connecting rod 1, for example, an alpha instrument can be measured at a position 5mm higher than the rotating disc 2, and a beta instrument can be measured at a position 10mm higher than the rotating disc 2. Meanwhile, as the turntable 2 is rotationally connected with the connecting rod 1, and the plurality of accommodating grooves 21 are formed in the turntable 2, the automatic switching of the standard plane source can be realized through the rotation of the driving turntable 2, the calibration efficiency is improved, the switching and positioning of the standard plane source and the instrument to be calibrated can be realized, the time and the energy of manual operation are saved, the labor cost is reduced, the risk of human errors is reduced, and the investment of human resources is saved.
In the present embodiment, the number of the receiving grooves 21 is three, and the three receiving grooves 21 are arranged at intervals along the central axis of the connecting rod 1. In other embodiments, the number of the accommodating grooves 21 can be adjusted according to actual requirements, which is not limited herein.
Specifically, the surface contamination monitor calibration apparatus further includes a rotation driver 4 mounted on the connection rod 1 and configured to drive the turntable 2 to perform a rotation motion, and a lifting driver (not shown) mounted on the connection rod 1 and configured to drive the storage tray 3 to perform a lifting motion. The rotary drive 4 and the lifting drive may be stepper motors, and in other embodiments the rotary drive 4 and the lifting drive may be servo motors, air cylinders or other driving devices.

In addition, the surface pollution monitor calibrating device also comprises a control system, and the control system is in communication connection with the lifting driver, the camera 6 and the rotary driver 4. The camera 6 may be an intelligent camera, which may be located above the object placing tray 3, for acquiring a data image of the surface pollution monitor, and then the control system acquires data through the camera 6, so as to record, store and process the data of the surface pollution monitor. At the same time the control system can also control the movement of the lifting drive as well as the rotary drive 4.
In addition, the surface pollution monitor calibrating device further comprises a base 7 arranged at the bottom of the connecting rod 1, wherein the base 7 is fixedly connected with the connecting rod 1 through welding, or the base 7 is detachably connected with the connecting rod 1. The base 7 is used for positioning and supporting the connecting rod 1.
The working principle of the surface pollution monitor calibrating device is as follows:
The surface pollution monitor to be calibrated is placed on the object placing disc 3, a plurality of standard plane sources are respectively placed on the accommodating grooves 21 of the rotary disc 2, and then the rotary driver 4 is started to drive the rotary disc 2 to rotate through the control system. When the turntable 2 rotates, the standard plane source sequentially enters the detection positions of the surface pollution monitor, and at each different detection position, the camera 6 acquires real-time data images of the surface pollution monitor and transmits the real-time data images to the control system, and the control system records, stores and processes the data in real time, so that an original record and a calibration report are generated in the calibration process. In the working process of the surface pollution monitor calibrating device, if different types of surface pollution monitors need to be calibrated, the height position of the object placing disc 3 can be adjusted through the lifting driver.
The surface pollution monitor calibrating device has the beneficial effects that:

The operation flow is simplified, namely the camera 6 is used for reading the data image of the surface pollution monitor and is connected with the control system in real time, manual recording of data and complicated data processing are not needed, and in addition, the control system can automatically record, store and process the data, so that the operation flow is further simplified. The user can complete the whole calibration process by only carrying out a small amount of setting and instruction input on the control system;
