[0032] Please refer to Figures 1 to 4 This embodiment provides a pipeline radiation monitoring device, comprising: a frame structure 1 with an internal installation space through which the pipeline to be monitored can pass; the frame structure 1 includes multiple columns 11, multiple first connecting rods 12, and multiple second connecting rods 13; multiple first connecting rods 12 are arranged parallel to each other between any two adjacent columns 11; multiple second connecting rods 13 are arranged parallel to each other between two first connecting rods 12 extending along the length direction of the pipeline to be monitored, and the length direction of the second connecting rods 13 is parallel to the length direction of the pipeline to be monitored; a monitoring component 2 for monitoring the activity concentration of gamma radionuclides in the pipeline to be monitored; the monitoring component 2 is detachably connected to any two adjacent first connecting rods 12; and / or, the monitoring component 2 is detachably connected to any two adjacent second connecting rods 13; and a display component 3 for displaying the activity concentration of gamma radionuclides in the pipeline to be monitored as monitored by the monitoring component 2; the display component 3 is detachably connected to any two adjacent connecting rods. Specifically, the frame structure 1 includes four columns 11, which are connected to the first connecting rods 12 to form a cuboid frame. With this configuration, by setting up the frame structure 1 and the monitoring component 2, the frame structure 1 includes multiple columns 11, multiple first connecting rods 12, and multiple second connecting rods 13. The monitoring component 2 is detachably connected to any two adjacent first connecting rods 12; and / or, the monitoring component 2 is detachably connected to any two adjacent second connecting rods 13. This modular design facilitates device maintenance and allows users to adjust the installation position of the monitoring component 2 according to the gas density in the pipeline to be monitored, making the device more versatile.

[0033] Alternatively, please refer to Figure 1 and Figure 2 The pipeline radiation monitoring device also includes multiple connecting plates 4, with a connecting plate 4 connected to the connection point of any column 11 and a connecting rod. This arrangement ensures the reliability of the connection between the column 11 and the first connecting rod 12, as well as the connection point between the column 11 and the second connecting rod 13, while also facilitating the installation and disassembly of the frame structure 1.

[0034] Optionally, the frame structure 1 also includes multiple legs 14 and multiple reinforcing members 15. Multiple columns 11 are fixedly connected to the multiple legs 14 in a one-to-one correspondence. Along the circumference of the columns 11, multiple reinforcing members 15 are spaced apart at the connection points between the legs 14 and the corresponding columns 11. This configuration, by adding legs 14 and reinforcing members 15 to the frame structure 1 and spaced out the reinforcing members 15 at the connection points between the columns 11 and the legs 14, improves the stability and strength of the frame structure 1, while also enhancing the convenience of installation and maintenance.

[0035] Alternatively, please refer to Figure 1 and Figure 2 The pipeline radiation monitoring device includes multiple monitoring components 2, which are spaced circumferentially along the pipeline to be monitored on the frame structure 1. Preferably, four monitoring components 2 are provided, and the monitoring angles of the four monitoring components 2 are perpendicular to each other. This arrangement facilitates multi-directional monitoring of radiation within the pipeline, reduces blind spots, and enhances the reliability of the device.

[0036] Alternatively, please refer to Figure 3 The monitoring component 2 includes a monitor 21, a lead chamber 22, a housing 23, and a cover 24. The monitor 21 is used to monitor the activity concentration of gamma radionuclides in the pipeline to be monitored. The housing 23 has an opening, and the cover 24 is used to open or close the opening. The monitor 21 is disposed in the housing 23, and the lead chamber 22 covers the monitor 21. Specifically, the housing 23 and the cover 24 are connected by a hinge, which facilitates the opening and closing of the cover 24 and makes it convenient for device maintenance. Covering the monitor 21 with the lead chamber 22 forms a lead shield for the monitor 21, which can effectively shield the monitor 21 from gamma ray interference in the external environment and prevent background radiation from falsely triggering or interfering with the monitor 21, thereby ensuring the accuracy of the monitoring results. At the same time, the lead chamber 22 can also prevent the monitor 21 from leaking radiation into the external environment when it detects a high activity concentration of radionuclides, protecting the safety of operators and the surrounding environment. In some embodiments, the detector 21 is a clinker scintillator detector, which is highly sensitive, stable, and durable.

[0037] Alternatively, please refer to Figure 3A fixing part 231 is provided on the outer wall of the housing 23, and the fixing part 231 is detachably connected to any two adjacent connecting rods. This configuration facilitates the disassembly and assembly of the monitoring component 2 when the monitoring position needs to be adjusted or when the monitoring component 2 malfunctions, improving the versatility of the device and the maintenance efficiency of the monitoring component 2.

[0038] Alternatively, please refer to Figure 3 The monitoring component 2 also includes two limiting plates 25, which are fixedly connected to the housing 23 and form a limiting groove. The monitor 21 is embedded in the limiting groove, and the lead chamber 22 is detachably connected to the limiting plates 25. This configuration provides a precise installation position for the monitor 21, ensuring that the monitor 21 is fixed and stable within the housing 23. This prevents the monitor 21 from shifting due to vibration, collision, or other external forces during use, thus avoiding deviations in the measurement results.

[0039] Alternatively, please refer to Figure 3 The monitoring component 2 also includes a signal interface 26, which is fixedly connected to the monitor 21. Specifically, the signal interface 26 is a junction box that collects the radiation signals received by the detector and converts them into digital signals for subsequent processing.

[0040] Alternatively, please refer to Figure 4 The display component 3 includes a housing 31, a rear cover 32, a display 33, and a power supply 34. The housing 31 has an opening, and both the display 33 and the power supply 34 are housed within the housing 31. The rear cover 32 is detachably connected to the housing 31, allowing the opening to be opened or closed. The display 33 displays the activity concentration of gamma radionuclides within the monitored pipeline as detected by the monitoring component 2. The housing 31 is detachably connected to any two adjacent connecting rods. This configuration allows the housing 31 to be detachably connected to any two adjacent connecting rods, enabling the display component 3 to be installed in the optimal location near the pipeline according to actual needs, facilitating observation and operation. Simultaneously, the display 33 allows operators or maintenance personnel to monitor the radiation level within the pipeline in real time, promptly detect abnormalities, and take appropriate measures, thus improving the reliability of the device.

[0041] Optionally, the pipeline radiation monitoring device also includes an indicator light 5, which is detachably connected to the top of the frame structure 1. This arrangement allows staff to more intuitively understand the radiation level inside the pipeline, facilitates timely detection of abnormalities, and improves the reliability of the device.
