[0037] The terms "first", "second", etc. are only used for convenience of description and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of technical features. The meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0038] The above terms are only for convenience of description and cannot be construed as a limitation to the technical solution of the present application.

[0039] A nuclear power plant pipeline radiation monitoring instrument provided by an embodiment of the present utility model. The nuclear power plant pipeline radiation monitoring instrument includes: an instrument main body, several groups of fixed ring structures, and cable ties.

[0040] A group of fixed ring structures includes two fixed rings, and each group of fixed ring structures is located on both sides of the instrument main body respectively.

[0041] Specifically, "each group of fixed ring structures is located on both sides of the instrument main body respectively" means that the fixed rings are placed on the left and right sides of the instrument main body. It can ensure the symmetry and balance of the equipment, help to disperse the load, reduce the risk of damage caused by uneven force, or to maintain the stability of the equipment during installation or operation. The number of fixed ring structures can be one group, two groups or more groups.

[0042] As Figure 1 shown, 001 is the instrument main body, 002 is the fixed ring structure, and 003 is the cable tie. In a feasible embodiment, the nuclear power plant pipeline radiation monitoring instrument includes: an instrument main body, two groups of fixed ring structures, and two cable ties. The number of cable ties can be greater than or equal to the number of fixed ring structures.

[0043] The cable tie is used to penetrate the openings on both sides of the instrument main body and fix the instrument main body on the pipeline.

[0044] A cable tie is a flexible strip used to fix, bundle, or protect cables, pipelines, and other structures, usually made of nylon, stainless steel, or other durable materials. In the present utility model, the cable tie is used to fix the instrument main body on the pipeline to ensure a stable and safe measurement environment. During specific operation, the cable tie needs to penetrate the fixed ring structures on both sides of the instrument main body. The fixed ring structures are preset on the instrument main body and are specifically used to cooperate with the use of the cable tie. Through these openings, the cable tie can be arranged around the pipeline and the instrument main body, thereby firmly binding the instrument to the pipeline.

[0045] Once the position of the instrument main body is correct, the cable tie will be tightened and locked. Usually, the cable tie will have a locking head to fix the length of the cable tie and maintain its tension. Using the cable tie to fix the position of the instrument main body is not only convenient for installation and removal, but also can absorb and relieve the vibration in the pipeline to a certain extent, preventing the instrument main body from shifting or being damaged due to vibration, and ensuring the accuracy of measurement and the long-term stability of the equipment. Using the cable tie to fix the instrument main body is a cost-effective, simple and reliable solution, enabling the present utility model to meet the requirements of various nuclear power radiation measurement scenarios. In some feasible embodiments, magic tapes can also be installed at both ends of the cable tie to improve the reuse rate of the cable tie.

[0046] The instrument main body includes: a controller, a nuclear detection module, a low-power processing module, and a storage module. As Figure 2As shown in the figure, the controller is respectively connected to the nuclear detection module, the low-power processing module, and the storage module. The controller is used to control the function switching of the instrument body; the nuclear detection module is used to measure the radiation level; the low-power processing module is used to change the instrument body into the low-power processing mode when the instrument body is in the non-working state; the storage module is used to record the working information of the instrument body.

[0047] The nuclear detection function is completed by the controller, the nuclear detection module, and the low-power processing module. The nuclear detection module is responsible for detecting and measuring the radiation level. This module usually includes one or more radiation detectors, such as Geiger counters, scintillation detectors, or semiconductor detectors, etc., which are used to convert the received radiation energy into electrical signals. These detectors have different sensitivities to different types of radiation (such as alpha particles, beta particles, gamma rays, etc.). The controller is the "brain" of the system. It receives the electrical signals from the nuclear detection module and processes and analyzes them. In a simplified configuration, the controller can be a microprocessor or a microcontroller, which is responsible for executing algorithms to analyze the output signals of the detectors and convert them into radiation level data that can be understood by users. In application scenarios that require long-term operation and are not easy to replace the power supply, such as fixed environmental monitoring or portable devices, low-power design becomes particularly important. This module includes a series of circuit design and software optimization measures, aiming to reduce the energy consumption of the entire system, extend the battery life, or enable the device to be powered by a small battery. This includes the use of energy-saving processors, low-power sensors, and sleep modes and other technologies.

[0048] Furthermore, the storage module of the instrument body is a key component for data storage and management, and is directly connected to the controller. It is responsible for recording the data collected by the sensors, such as working information such as radiation levels, and storing these data in the memory. The storage module usually uses non-volatile memory to ensure that the data will not be lost after power-off. The connection to the controller is achieved through serial communication protocols such as I2C, SPI, or UART, allowing the controller to read the stored data for processing and analysis, or write new data to the storage module. The storage module is also responsible for maintaining the integrity and security of the data, and may include encryption functions to prevent unauthorized access. In addition, it manages the organization method of the data, such as using a file system or a database to optimize data retrieval. In a portable instrument, the storage module also needs to consider power consumption management to extend the battery life. In short, the storage module is an indispensable part of the instrument body, which ensures the safe and reliable storage of data and provides a basis for the normal operation and data analysis of the instrument.

[0049] In a feasible embodiment, as Figure 3 shown, the width of the part that the fixed ring structure can pass through is A1, specifically, A1 can be 1.5 mm, and the width of the cable tie fixing position of the fixed ring structure is A2, specifically, A2 can be 10 mm. As Figure 4As shown, the thickness of the instrument body is A3, and specifically, A3 can be 28 mm. The instrument body plus the fixed ring structure is A4, and specifically, A4 can be 33 mm. As Figure 5 shown, the length of the instrument body is A5, specifically, A5 can be 118 mm, and the width is A6, specifically, A6 can be 120 mm.

[0050] In an executable embodiment, the instrument body includes a nylon housing; the nylon housing can withstand temperatures above 120 degrees Celsius.

[0051] The instrument body with a nylon housing can operate in a high-temperature environment and can withstand temperatures above 120 degrees Celsius, which is a significant advantage for nuclear power applications. First of all, the high-temperature resistance property enables the instrument to be used in high-temperature nuclear power processes without being damaged or losing its function due to excessive temperature. The high-temperature resistance property enables the instrument to resist temporary temperature peaks, which is particularly crucial when dealing with high-temperature fluids or gases. In addition, this property also maintains the accuracy of the instrument and extends the service life of the equipment. Secondly, nylon housings generally have good chemical stability and corrosion resistance, which means that in the face of corrosive chemical substances, the instrument housing can maintain its integrity and functionality, extending the service life of the equipment. In addition, the nylon housing also has good insulation performance and structural strength, providing protection for the measuring elements and ensuring the accuracy of measurement and the reliability of the equipment. Finally, the instrument body with a nylon housing can reduce the maintenance frequency and maintenance costs due to its temperature resistance and chemical corrosion resistance properties, improving the overall economic efficiency. Therefore, the instrument body with a nylon housing is very beneficial for nuclear power applications that require long-term stable operation in a high-temperature environment.

[0052] In addition to improving reliability and durability, instruments with high-temperature resistant nylon housings also help reduce maintenance requirements and lower long-term operating costs. The housings of such instruments are usually lightweight, easy to install and move, while providing sufficient protection against mechanical impacts and daily wear.

The GM counter tube has good stability and can maintain its performance in a changing environment, making it suitable for long-term continuous monitoring. The GM counter tube is simple to manufacture, low in cost, and has extremely high stability, making it very suitable for working in high-temperature situations.

[0059] In an executable embodiment, the low-power processing module includes a micro control unit. The low-power processing module controls the working states of different modules through intelligent algorithms, and only starts high-power-consuming modules when needed, thereby effectively reducing the average power consumption. The low-power operational amplifier is used to process weak signals to ensure low power consumption during the signal amplification process. The dedicated low-power power management circuit is responsible for optimizing the battery usage efficiency and extending the working time of the device within a single charging cycle.

[0060] In an executable embodiment, the storage module is a magnetic memory.

[0061] Specifically, compared with charge storage-based memories, magnetic memories consume less energy when writing and reading data. In addition, they have stronger adaptability to environmental conditions and can operate stably within a wide range of temperatures and humidities. In some executable embodiments, the storage space of the storage module is not less than 64 KB, which can meet the storage requirements of 1000 pieces of data.

[0063] Specifically, in the instrument body, the display module and the button module are important components of the user interface. The display module is responsible for receiving and presenting the data sent by the nuclear detection module, such as radiation levels, environmental monitoring results, etc., enabling users to intuitively understand the current status. The button module is used to issue preset working information, such as setting parameters, starting measurements, or selecting working modes, to ensure that the instrument operates according to the user's requirements. The display module and the button module are respectively connected to the nuclear detection module, forming an effective information feedback and instruction input mechanism, enhancing the interactivity and usability of the instrument.

[0064] In some executable embodiments, the display module includes a display screen and a backlight board.

[0065] Specifically, the display screen can select a segment LCD screen and a backlight board in the early stage, and the specific structural effect is as Figure 10 shown.

[0066] Furthermore, the display module is used to present the data sent by the nuclear detection module to ensure that users can obtain information such as radiation levels in real time and accurately.

[0067] In some executable embodiments, the controller can select an STM32 series processor. The STM32 series processor can support segment screens.

[0068] In some executable embodiments, the button module includes waterproof buttons. The button module allows users to preset working parameters, such as setting alarm thresholds, selecting measurement modes, etc., making the instrument operation more flexible and convenient.

[0069] Furthermore, the button module includes 4 small waterproof buttons. The 4 small waterproof buttons are respectively used for power on / off, page turning / switching, confirmation, and returning to the previous level. The button module can support functions such as CPS switching display, alarm threshold switching display, communication interval switching display, communication time interval setting, alarm threshold setting, and data export through buttons.

[0070] In an executable embodiment, the instrument body further includes: an acoustic-optic alarm module. The acoustic-optic alarm module is connected to the nuclear detection module. The acoustic-optic alarm module is used to issue an alarm prompt according to the instructions of the nuclear detection module.

[0071] Specifically, the acoustic-optic alarm module of the instrument body is a key component of the safety monitoring system. When the nuclear detection module detects an abnormal radiation level, the acoustic-optic alarm module will be immediately activated, emitting a sharp alarm sound and bright flashing lights to remind the user to take emergency measures. Through the acoustic-optic alarm module, it is ensured that a timely response can be made at a critical moment. The acoustic-optic alarm module is closely connected to the nuclear detection module, forming an efficient information transmission and processing mechanism, enabling the instrument to quickly respond and issue an alarm. In this way, the acoustic-optic alarm module improves the safety and reliability of the instrument, providing more comprehensive protection for the user.

[0072] In some practicable embodiments, the acoustic-optic alarm module includes waterproof lights.

[0073] Specifically, the acoustic-optic alarm module can be two small waterproof lights, respectively used to indicate the working state of the device and the γ radioactive level. The selection is specifically based on the usage scenario and is not limited here.

[0079] In some executable embodiments, the wireless communication module also supports remote instruction issuance, allowing users to perform operations such as parameter setting and working mode switching on the instrument through a smart terminal, improving the convenience and flexibility of using the instrument. The wireless communication module is closely connected to the nuclear detection module, forming a complete information transmission and processing system, enabling the instrument to meet the requirements of modern informatization and intelligence. Adding the wireless communication module to the instrument body greatly enhances the communication ability and intelligence level of the instrument, bringing a more convenient user experience.

[0081] Specifically, the power management module is an important part of the instrument body, responsible for managing the charging and discharging process of the battery to ensure the safe and efficient operation of the battery.

[0082] In some executable embodiments, the number of batteries of the power management module is determined according to the power consumption of each module of the instrument body, the data transmission frequency, and the battery life. For example, in a scenario where the battery life is more than 7 days and the data transmission frequency is 1 - 300 s (default is 30 s), the power management module requires at least 4 18650 lithium batteries (or 2 26650 lithium battery packs) to provide power. Further, boost and voltage stabilization circuits can also be designed to supply power to each module. This is only an example for illustration and is not limited.

[0083] Further, the power management module further includes a voltage monitoring circuit capable of obtaining the battery power in real time.

[0084] In an executable embodiment, the power management module has an intelligent charging function, which can automatically adjust the charging current and voltage according to the battery state to avoid overcharging or undercharging.

The power management module also has a power monitoring function, which can accurately obtain the remaining power of the battery and display it through the display module, facilitating users to master the battery state at any time. In addition, this module also has protection functions such as overcurrent, overvoltage, and over-temperature to ensure that the circuit can be cut off in time in case of abnormalities, guaranteeing the safe operation of the system.

[0085] In an executable embodiment, the instrument body further includes: an external interface module. The external interface module is connected to the power management module and an external power supply. The external power supply supplies power to the power management module through the external interface module.

[0086] Specifically, the external interface module is a key part of the instrument body, providing the instrument with rich external connection capabilities. This module usually includes various types of interfaces, such as USB, RS232, RS485, Ethernet interfaces, etc., and supports connections with external devices such as computers, printers, other instruments or network systems. Through these interfaces, the instrument can achieve data import and export, facilitating users to perform data analysis and backup.

[0087] Furthermore, the USB adopts a small Type-C interface solution and supports charging of lithium batteries.

[0088] Furthermore, power supply through the external interface can provide a stable and reliable power source for the instrument, ensuring its continuous and efficient operation. Secondly, the connection between the external interface module and the external power supply can be replaced or adjusted according to the usage scenario to meet different power consumption requirements in different usage scenarios and optimize energy utilization. When the instrument battery runs out or cannot be used, the power supply provided by the external interface module offers a convenient alternative solution to ensure the continuous operation of the instrument. In addition, it also facilitates the sharing of power resources between the instrument and other devices, reducing the overall energy consumption of the system.

[0089] In some executable embodiments, the external interface module can be connected to other devices, enabling users to update the firmware program of the instrument through the interface to obtain new functions or improved performance.
