[0003] Currently, radioactive liquid specific activity detectors are typically installed using bolts to fix the detector in a specific location. Bolt connections provide strong clamping force, ensuring a tight fit between the detector and the installation location. During operation, the bolts effectively resist external forces such as vibration and impact, ensuring that the device will not easily loosen or shift, thereby guaranteeing the stability and accuracy of the measurement.

[0004] While bolted installation effectively resists vibration and external impacts, preventing device movement, bolts can loosen due to factors such as vibration and temperature changes. Regular checks and tightening are necessary. Failure to promptly detect and address loose bolts can lead to displacement or damage to the detection device, affecting the accuracy of measurement results and the safety of the equipment. Therefore, an embedded radioactive liquid specific activity detection device is proposed to address these issues. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model is provided: an embedded radioactive liquid specific activity detection device, including a disc block 7 and a connecting tube 9. Multiple telescopic fixing components are provided on the inner side of the disc block 7. A housing 2 is fixedly connected to the top of the disc block 7. A lifting component is provided on the inner side of the housing 2. Two support blocks 11 are fixedly connected to the top of the disc block 7. A snap-fit ​​component is provided on the inner side of the two support blocks 11. A protective component is provided on the outer side of the connecting tube 9.

[0037] The telescopic fixing assembly includes a sliding groove 15. Multiple sliding grooves 15 are formed on the inner side of the disc block 7. Perforated plates 14 are slidably connected to the inner sides of each sliding groove 15. Multiple fixing bolts 16 are installed on the inner side of the disc block 7, and these bolts are all installed on the inner sides of the perforated plates 14. Connecting blocks 17 are fixedly connected to the side ends of each perforated plate 14. Arc-shaped locking blocks 8 are rotatably connected to the inner sides of the ends of each connecting block 17. Workers can slide the perforated plates 14 within the sliding grooves 15 according to the actual size of the connecting pipe 9 and installation requirements, thereby adjusting their position within the disc block 7. Once the position of the perforated plate 14 is determined, the fixing bolts 16 are passed through the disc block 7 and screwed into the inner sides of the perforated plates 14 to firmly fix them in place. Anti-slip strips 23 are fixedly connected to the outer sides of the ends of each of the arc-shaped locking blocks 8, and these anti-slip strips 23 are slidably connected to the inner sides of the connecting pipe 9. The operator can rotate the arc-shaped locking block 8 to make the anti-slip strip 23 on the outer side of the end of the arc-shaped locking block 8 fit tightly against the inner side of the connecting pipe 9. The anti-slip strip 23 increases the friction between the arc-shaped locking block 8 and the connecting pipe 9, ensuring that the device is installed firmly inside the connecting pipe 9 and is not easy to shake or shift.

[0038] Reference Figure 2 , Figure 3 , Figure 6 and Figure 7 The lifting assembly includes a toothed plate 3, which is slidably connected to the inner side of the housing 2 and also slidably connected to the inner side of the disc block 7. Gears 6 are rotatably connected to the inner sides of both support blocks 11, and the gears 6 are meshed with the sides of the toothed plate 3. A drive motor 5 is fixedly connected to the inner side of the housing 2, and the output end of the drive motor 5 is fixedly connected to the inner side of the gears 6. Starting the drive motor 5 drives the gears 6 to rotate. Because the gears 6 and the toothed plate 3 are meshed, the gears 6 move up and down together. By controlling the forward and reverse rotation and the number of rotations of the drive motor 5, the lifting height of the toothed plate 3 can be precisely controlled, thereby adjusting the position of the semiconductor detector 13 within the connecting tube 9. Positioning blocks 21 are fixedly connected to the inner sides of both ends of the disc block 7. Sliding grooves 20 are formed on the inner sides of both ends of the toothed block 3. The positioning blocks 21 are slidably connected to the inner sides of the two sliding grooves 20. By sliding within the sliding grooves 20 on the inner sides of the toothed block 3, the positioning blocks 21 on the inner sides of both ends of the disc block 7 provide guidance and positioning, ensuring that the toothed block 3 can only move in a straight line along the vertical direction. A positioning block 10 is fixedly connected to the bottom of the disc block 7, and the toothed block 3 is slidably connected to the inner side of the positioning block 10. The toothed block 3 also slides within the positioning block 10 at the bottom of the disc block 7, further ensuring the stability and accuracy of its movement.

[0039] Reference Figure 2 , Figure 3 and Figure 5The snap-fit ​​assembly includes a housing 12, which is fixedly connected to the inner sides of two support blocks 11. An electric push rod 18 is fixedly connected to the inner side of the housing 12, and a locking block 19 is fixedly connected to the end of the electric push rod 18. The end of the locking block 19 is slidably connected to the side of the toothed plate 3. When the toothed plate 3 moves the semiconductor detector 13 to a suitable detection position, the electric push rod 18 is activated to push the locking block 19 at its end to slide towards the side of the toothed plate 3 until the end of the locking block 19 is embedded in the corresponding position on the side of the toothed plate 3, thus fixing the toothed plate 3 in the current position. This prevents the detector position from changing due to external factors during the detection process, ensuring the accuracy and stability of the detection results.

[0040] Reference Figure 1 , Figure 2 and Figure 3 The protective assembly includes a lead shield 1, which is slidably connected to the outside of the connecting pipe 9. A sealing ring 22 is fixedly connected to the inner side of the end of the lead shield 1, and the sealing ring 22 is slidably connected to the inner side of the end of the connecting pipe 9. The sealing ring 22 fixedly connected to the inner side of the end of the lead shield 1 fits tightly with the inner side of the end of the connecting pipe 9 to prevent leakage of radioactive liquid and ensure the safety and reliability of the entire detection process. A thread 4 is fixedly connected to the outer side of the bottom of the connecting pipe 9, and the thread 4 connects to an external pipe. By rotating the connecting pipe 9, the thread 4 is tightened to the corresponding interface of the external pipe, achieving a sealed connection between the device and the external pipe, ensuring that the radioactive liquid can flow smoothly into the connecting pipe 9 for detection. A semiconductor detector 13 is fixedly connected to the bottom of the toothed plate 3, and the semiconductor detector 13 is slidably connected inside the connecting pipe 9. The semiconductor detector 13 has a high energy resolution and can accurately distinguish rays of different energies. By analyzing the electrical signal output by the detector, the energy distribution of the rays can be obtained.

[0041] Working Principle: Since the radiation in radioactive liquids can interact with biomolecules in human cells, damaging their normal structure and function, this method utilizes a device installed inside the connecting pipe 9 and connected to the radioactive liquid pipeline to detect radiation and minimize harm to the human body. When installing the device onto the connecting pipe 9, the operator adjusts its position by sliding the perforated plate 14 within the groove 15 of the disc block 7. Once the position is determined, a fixing bolt 16 is passed through the disc block 7 and tightened onto the inside of the perforated plate 14 to secure it. Then, by rotating the arc-shaped locking block 8, the anti-slip strip 23 on the arc-shaped locking block 8 is tightly fitted against the inside of the connecting pipe 9, thus fixing the device. The anti-slip strip 23 increases friction and prevents the device from sliding. This ensures the device is securely installed inside the connecting pipe 9.

[0042] The lead shield 1 on the outside of the connecting pipe 9 can block and absorb radioactive rays, reducing the harm of rays to the surrounding environment and operators, while also reducing the interference of external radiation on the detector measurement results. The sealing ring 22 on the inner side of the end of the lead shield 1 fits tightly with the inner side of the end of the connecting pipe 9 to prevent leakage of radioactive liquid and play a role in sealing and protection.

[0043] When the semiconductor detector 13 needs to be adjusted to detect the specific activity of the liquid containing radioactive rays, the drive motor 5 is started to drive the gear 6 to rotate. Since the gear 6 and the toothed plate 3 are meshed, the gear 6 rotates while driving the toothed plate 3 to move up and down. Since the semiconductor detector 13 is installed at the bottom of the toothed plate 3, the height of the semiconductor detector 13 can be precisely adjusted inside the connecting tube 9.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
