Description

Technical Field

[0001] This utility model relates to a radiation testing device, belonging to the field of metrology and test evaluation. Background Technology

[0002] With the widespread application of nuclear technology in energy, medicine, industry, and defense, the performance testing and calibration of nuclear radiation measurement systems have become increasingly important. Reliable nuclear radiation measurement systems are crucial for ensuring personnel safety, environmental monitoring, and nuclear emergency response. Currently, traditional methods for sensitivity testing and performance verification of nuclear radiation measurement systems typically employ fixed radiation sources or manually carried radiation sources for mobile testing. However, these methods have the following technical drawbacks:

[0003] Safety concerns: Manually operating radioactive sources poses a risk of radiation exposure, especially in complex or high-risk environments (such as nuclear accident sites or radioactive waste disposal areas), where close contact with radioactive sources may lead to health damage.

[0004] Low testing efficiency: Fixed radiation sources can only simulate static radiation fields and cannot dynamically verify the moving target tracking capability of radiation reconnaissance systems; while the method of manually moving radiation sources is limited by the operator's walking path and speed, making it difficult to achieve standardized and repeatable testing procedures.

[0005] Poor controllability: It is difficult to accurately control the rise and fall height, movement trajectory and speed of the radiation source by manual operation, resulting in poor comparability of test data and affecting the calibration accuracy of the radiation detection system.

[0006] Poor environmental adaptability: In complex terrain (such as ruins, rugged roads) or dangerous areas (such as high temperature, high radiation areas), manual testing may not be possible, which limits the practical verification scenarios of radiation monitoring equipment.

[0007] To address these issues, some automated solutions exist in existing technologies, such as moving radiation sources using robotic arms or rail systems. However, these devices are typically bulky, complex to deploy, and dependent on fixed infrastructure, making them unsuitable for field or mobile testing needs. Furthermore, existing technologies for carrying radiation sources on unmanned vehicles primarily focus on radiation inspection rather than dynamic testing of radiation reconnaissance systems, lacking integrated designs for raising, lowering, and remotely controlling the movement of radiation sources.

[0043] The present invention will now be explained and described in conjunction with the accompanying drawings.

[0044] A radiation testing device such as Figure 1 As shown, it includes: control box 1, calibration frame fixing plate 2, calibration frame base plate 3, counterweight 4, calibration frame 5, electric cylinder support frame 6, electric cylinder clamp 7, scale fixing block 8, scale connecting block 9, source clamp connecting plate 10, source clamp 11, M2 screw 12, M3 screw 13, M5 screw 14, M8 screw 15, cap nut 16, thrust ball bearing 17, 6×35 pin shaft 18, 6×45 pin shaft 19, 8×35 pin shaft 20, composite copper sleeve 21, scale motor 22, electric push rod 23, Torx handle screw 24, double-sided tape measure 25, laser rangefinder 26, ultra-high-definition camera 27, photoelectric switch 28, wired control chassis 29, telescopic protective cover 30.

[0045] like Figure 1 The control box 1 is installed on the online control chassis 29 and is responsible for controlling the movement and testing of the testing device.

[0046] like Figure 3 The calibration frame fixing plate 2 is installed and fixed on the control chassis 29 by M5 screws 14. The calibration frame fixing plate 2 is the fixed base of the calibration mechanism.

[0047] like Figure 3 and Figure 5 Detail magnification Figure I As shown: The calibration frame base plate 3 is fixed to the calibration frame fixing plate 2 by a thrust ball bearing 17 and a Torx handle screw 24.

[0048] like Figure 3 The counterweight 4 is fixed to the rear end of the calibration frame base plate 3 by M8 screws 15.

[0049] like Figure 1 and Figure 5 Detail magnification Figure III As shown: The upper part of the calibration frame 5 is fixed to the front end of the calibration frame base plate 3 by an 8×35 pin 20 and a composite copper sleeve 21. The upper part of the calibration frame 5 can rotate around the pin 20. The bottom of the calibration frame 5 is connected to the bottom lug of the electric push rod 23 by a 6×45 pin 19 and a cap nut 16.

[0050] like Figure 1 , Figure 2 , Figure 3 The bottom of the electric cylinder support frame 6 is fixed to the rear front end of the calibration frame base plate 3 by an 8×35 pin 20 and a composite copper sleeve 21. The bottom of the electric cylinder support frame 6 can rotate around the pin 20. The upper part of the electric cylinder support frame 6 is fixed to the electric cylinder clamp 7 to stably fix the electric push rod 23 and ensure that the electric push rod 23 and the calibration frame base plate 3 form a 90° angle.

[0051] like Figure 1 , Figure 2 There are three electric cylinder clamps 7, which are respectively installed on the top of the electric push rod 23 and the lower part of the middle box. The electric cylinder clamps 7 installed on the top and bottom of the electric push rod 23 are all equipped with photoelectric switches 28. The electric cylinder clamp 7 installed in the middle part of the electric push rod 23 is fixed to the upper part of the electric cylinder support frame 6 with a Torx handle screw 24.

[0052] like Figure 1 , Figure 2 The lower end of the ruler fixing block 8 is fixed to the spindle of the electric push rod 23 by a 6×35 pin 18 and a cap nut 16. The upper end of the ruler fixing block 8 is connected to the modified double-sided tape measure 25. The side of the double-sided tape measure 25 is connected to the ruler motor 22.

[0053] like Figure 1 , Figure 2 The ruler connecting block 9 connects the heads of the upper and lower double-sided measuring tapes 25. The lower double-sided measuring tape is connected to the upper double-sided measuring tape as one unit through the ruler connecting block 9. The upper double-sided measuring tape has been modified to eliminate the spiral spring core and uses the ruler motor 22 to drive the measuring tape and the ruler connecting block 9 to move up and down.

[0054] like Figure 1 , Figure 2 The upper end of the source clamp connecting plate 10 is connected to the ruler connecting block 9 with a rivet, and the source clamp connecting plate 10 can rotate around the rivet. When the wire-controlled chassis 29 moves, if there are obstacles such as small stones on the road, the source clamp connecting plate 10 will rotate and swing around the rivet to avoid the obstacles.

[0055] like Figure 1 , Figure 2 , Figure 5 As shown in enlarged details VI and VII, the source clip 11 consists of a fixed part and a movable part. The fixed part of the source clip 11 is installed at the bottom of the source clip connecting plate 10, and the movable part of the source clip 11 is installed inside the fixed part. The outer side of the movable part of the source clip 11 has two small holes. Inserting long tweezers into these holes and rotating it 180° will cause the movable part of the source clip 11 to rotate out, allowing the radioactive source to be picked up with the tweezers and placed into the radioactive source storage box, thus completing the storage of the radioactive source. Similarly, reversing this process will complete the placement of the radioactive source.

[0056] like Figure 1 , Figure 3 The laser rangefinder 26 is installed on the bottom left side of the calibration frame 5 and is used to detect the distance between the radiation source and the ground. When the scale motor 22 drives the double-sided tape measure 25, the scale connecting block 9, the source clamp connecting plate 10, the source clamp 11 and the radiation source to move up and down, the laser rangefinder 26 will detect the movement of the laser radiation plate fixed on the scale connecting block 9, thereby detecting the distance between the radiation source and the ground.

[0057] like Figure 1 , Figure 3 The ultra-high-definition camera 27 is fixed to the bottom right side of the calibration frame 5 and is used to observe the scale numbers displayed when the double-sided measuring tape 25 is pulled out, thereby determining the distance between the radiation source and the ground.

[0058] like Figure 1 , Figure 2 The photoelectric switch 28 is installed on the electric cylinder clamp 7. The photoelectric switch 28 is used to locate the zero point of the radiation source and the midpoint of 1500mm, and to control the start and stop of the scale motor 22 at the extreme position.

[0059] like Figure 1 , Figure 2 , Figure 3 The wire-controlled chassis 29 is a motion chassis that carries the main structure of the testing device. It drives the testing device to move along a predetermined path to complete the testing task.

[0060] like Figure 1 , Figure 2 , Figure 3 The telescopic protective cover 30 is used to completely cover and protect the stored test equipment after the test task is completed.

[0061] like Figure 4 To put the stored testing equipment into working condition, first open the latch lock on the telescopic protective cover 30, pull the telescopic protective cover 30 to both sides to the outside of the base plate of the telescopic protective cover 30, loosen the Torx handle screw 24 on the calibration frame base plate 3, rotate the calibration frame base plate 3 90°, then rotate the calibration frame 5 and electric push rod 23 downwards 90°, rotate the electric cylinder support frame 6 and fix it to the electric cylinder clamp 7, tighten the Torx handle screw 24, and finally pull the telescopic protective cover 30 inwards to the inside of the base plate, and fix the telescopic protective cover 30 with pins. Figure 1 , Figure 2 , Figure 3 As shown, the radiation testing device enters the working state, and the method of storing the radiation testing device is the reverse of the above process.
