Description

Technical Field

[0001] This utility model relates to the field of nuclear radiation environment detection technology, and in particular to a nuclear detection unmanned aerial vehicle (UAV) payload module. Background Technology

[0002] With the widespread application of nuclear technology in industry, medicine, energy, and other fields, the importance of nuclear radiation environment monitoring is becoming increasingly prominent. Unmanned aerial vehicles (UAVs), with their advantages of high mobility, rapid response, and access to complex or hazardous areas, have become important carriers for nuclear radiation detection. The payload module of a nuclear detection UAV, as a core functional component, directly affects detection efficiency and data reliability. Currently, UAV payload modules for nuclear radiation detection have achieved certain development. These modules, by carrying radiation detectors, can collect information such as the nuclear radiation dose and type in the target area and transmit the data to the ground control system, providing crucial information for radiation environment assessment and emergency response.

[0003] However, existing nuclear detection drone payload modules still have many shortcomings in practical applications: In terms of docking with the drone host, traditional modules rely on complex mechanical connections and independent cable connections. During installation, the position needs to be repeatedly adjusted to ensure good electrical contact, which is not only time-consuming and labor-intensive, but also difficult to adapt to the rapid deployment requirements in emergency scenarios. Moreover, after docking, the connection is prone to loosening due to vibration, resulting in signal transmission interruption or unstable power supply. In terms of structural layout, the internal component layout of the module is unreasonable. The detector and signal processing components lack a unified support and fixing structure, which not only results in a large module size and low space utilization, but also increases the difficulty of later maintenance. Especially when different detectors need to be replaced, the disassembly and assembly process is more cumbersome. Summary of the Invention

[0004] To address the above problems, this utility model provides a nuclear detection drone payload module, including a housing for carrying internal components. Inside the housing is a component support frame, on which are mounted a detection component for detecting nuclear radiation and a control component for processing detection signals and transmitting signals. The housing is provided with a quick-connect structure for docking, which includes a positioning component on the housing connection surface, a locking component for quick locking, and a quick-connect electrical component for electrical connection.

[0008] In one embodiment, a sealing groove is provided at the shell connection of the housing, and a sealing strip is provided in the sealing groove. The sealing strip is pressed and fixed by a bolt assembly.

[0009] In one embodiment, a plurality of mounting and positioning holes are evenly distributed inside the housing, and the component support frame is connected to the mounting and positioning holes by bolt assemblies to adjust the mounting position of the component support frame inside the housing.

[0010] In one embodiment, the detection assembly includes a scintillator detector and a high-range GM tube detector, wherein the scintillator detector and the high-range GM tube detector do not obstruct each other in the horizontal and vertical directions.

[0026] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0027] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0028] like Figure 1-3 As shown, a nuclear detection drone payload module includes a housing 1 for carrying internal components. Inside the housing 1, there is a component support frame 2. The component support frame 2 is equipped with a detection component 3 for detecting nuclear radiation and a control component 4 for processing detection signals and transmitting signals. The housing 1 is equipped with a quick-connect structure 5 for docking. The quick-connect structure 5 includes a positioning component disposed on the housing connection surface, a locking component for quick locking, and a quick-connect electrical component for electrical connection.

[0029] Specifically, the enclosure 1 is enclosed, providing installation space and protection for all internal components. Inside enclosure 1 is a component support frame 2, which serves as the mounting carrier for each core functional component. It houses the detection component 3 and control component 4. The control component 4 and detection component 3 communicate via specific connection lines, forming a complete signal processing system. The quick-connect structure 5 on enclosure 1 is crucial for docking with the UAV host. Positioning components are specifically distributed on the docking surface of enclosure 1, cooperating with the corresponding positioning structure on the UAV host to ensure accurate positioning during docking. Locking components are installed on the edge or at specific locations on the docking surface of enclosure 1. After positioning, the locking components securely lock enclosure 1 to the UAV host, preventing loosening. Quick-connect electrical components are also located on the docking surface of enclosure 1, corresponding to the electrical interfaces on the UAV host, enabling power and signal transmission. When the nuclear detection UAV payload module needs to be installed onto the UAV host, the positioning components on the docking surface of enclosure 1 are aligned with the corresponding positioning structure on the UAV host to initially position the module. Subsequently, the locking assembly is operated to securely lock the housing 1 to the UAV host, ensuring a stable connection. At this point, the quick-connect electrical components on housing 1 successfully connect to the electrical interface of the UAV host, establishing a power supply path and a signal transmission path. After the UAV host starts up, it supplies power to the payload module via the quick-connect electrical components, and the module begins to operate. The detection component 3 starts up under electric drive, detecting nuclear radiation in the surrounding environment. Different detection components 3, based on their own characteristics, capture different ranges or types of nuclear radiation and convert the detected nuclear radiation information into corresponding electrical signals, i.e., detection signals, which are transmitted to the control component 4 through the connection line. After receiving the signals, the control component 4 processes the signals according to a preset program and algorithm, including signal amplification, filtering, and analysis, converting the original detection signals into meaningful nuclear radiation data information. After processing, the control component 4 transmits this data information to the UAV host via the quick-connect electrical components. The UAV host then transmits the data to the ground control system, thus completing the entire process of nuclear radiation detection signal acquisition, processing, and transmission.In this application, a quick-connect structure 5 is incorporated, in which a positioning component ensures precise positioning of the housing 1 when docking with the UAV host, a locking component ensures stable connection, and a quick-connect electrical component enables rapid power and signal connection. These three components work synergistically to not only achieve rapid docking of the housing 1 with the UAV host but also ensure docking quality, significantly improving the efficiency of module installation and replacement, and enabling the UAV to quickly switch mission states. A component support frame 2 is installed inside the housing 1, housing the detection component 3 and control component 4, providing each component with a fixed installation position. This facilitates later inspection, repair, and maintenance of the module, while also improving internal space utilization and making the overall structure more compact. The control component 4 and detection component 3 ensure the validity and accuracy of the detection data, and the quick-connect electrical component rapidly transmits the processed data to the UAV host, achieving efficient data transmission and providing timely data support for subsequent analysis and decision-making.

[0030] like Figure 1 As shown, the positioning component includes multiple positioning pins 51 disposed on the connecting surface of the housing, and the drone host is provided with positioning holes that are adapted to the positioning pins 51.

[0031] Specifically, by setting multiple positioning pins 51 on the connecting surface of the housing, and by setting positioning holes on the drone host that are compatible with the positioning pins 51, the precise matching of the positioning pins 51 and the positioning holes can quickly achieve the alignment of the housing 1 and the drone host, reduce the adjustment time during the docking process, and ensure the accuracy of the connection position of the two; the distribution of multiple positioning pins 51 further improves the structural stability and positioning accuracy after docking, thereby ensuring the accuracy and stability of the connection between the entire module and the host.

[0032] like Figure 1 , 3 As shown, the locking assembly includes locking buckles 52 disposed on both sides of the housing 1, the locking buckles 52 being used to press and fix the housing 1 to the drone host.

[0033] Specifically, locking buckles 52 are provided on both sides of the housing 1. After the housing 1 and the drone host are precisely aligned by the positioning component, the locking buckles 52 on both sides firmly fix the housing 1 and the host into one unit, effectively preventing the connection from loosening or falling off due to vibration and turbulence during drone flight. At the same time, the locking buckles 52 on both sides are easy to operate and can quickly complete the locking and unlocking actions. Combined with the precise positioning of the positioning component, the stability of the connection is guaranteed, further improving the efficiency of module installation and replacement.

[0034] like Figure 1As shown, the quick-connect electrical component is a spring pin 53, which is disposed on the connecting surface of the housing 1 and is used to achieve electrical connection with the corresponding interface on the UAV host.

[0035] Specifically, the quick-connect electrical component is a spring pin 53 installed on the housing connection surface. After the housing 1 and the UAV host are aligned by the positioning component and fixed by the locking component, the spring pin 53 can make tight contact with the corresponding interface of the host by its own elasticity, ensuring the stability of power supply and signal transmission, and effectively avoiding poor contact caused by vibration, installation error, etc. At the same time, the structural design of the spring pin 53 is adapted to the quick-connect requirements, and can quickly complete the electrical connection during module installation and replacement without complicated wiring operations. Together with the positioning component and the locking component, it further improves the efficiency and reliability of the electrical connection between the module and the host, and ensures the continuity of detection signal and power transmission.

[0036] like Figure 2 , 4 As shown, a sealing groove 11 is provided at the shell connection of the housing 1, and a sealing strip is provided in the sealing groove 11. The sealing strip is pressed and fixed by a bolt assembly.

[0037] Specifically, a sealing groove 11 is provided at the shell connection, and a sealing strip is installed in the groove. The sealing strip is then pressed and fixed by anti-loosening screws. Under the action of the pressing force, the sealing strip can tightly fit the gap of the shell connection surface, effectively preventing external dust, moisture and other impurities from entering the interior of the enclosure, and avoiding the internal detection and control components from being affected by contamination or moisture. At the same time, the tightening method of the anti-loosening screws ensures that the sealing strip maintains a stable sealing effect over a long period of time. Even when the drone is vibrating during flight, it can maintain good sealing performance, providing a reliable protective environment for the internal components of the enclosure 1, and achieving an overall protection level of ≥IP67.

[0038] like Figure 2 As shown, the housing 1 has a plurality of mounting and positioning holes 12 evenly distributed inside. The component support frame 2 is connected to the mounting and positioning holes 12 by bolt assembly to adjust the mounting position of the component support frame 2 inside the housing 1.

[0039] Specifically, the multiple mounting and positioning holes 12 allow the new component support frame 2 to be fixed by selecting different mounting and positioning holes 12 when the specifications of the detection and control components change and the component support frame 2 needs to be replaced. This allows for flexible changes in the overall distribution of the detection and control components on the new component support frame 2, thereby adjusting the center of gravity of the module and ensuring that the center of gravity of the module and the UAV host are always matched. This effectively avoids the impact on flight stability caused by the shift in the center of gravity due to component replacement. It also improves the compatibility of the module with detection and control components of different specifications and enhances the flexibility of internal structure adjustment.

[0040] like Figure 2 , 5 As shown, the detection component 3 includes a scintillator detector 31 and a high-range GM tube detector 32, and the scintillator detector 31 and the high-range GM tube detector 32 do not obstruct each other in the horizontal and vertical directions.

[0041] Specifically, the scintillator detector 31 and the high-range GM tube detector 32 do not obstruct each other in the horizontal and vertical directions. The scintillator detector 31 is suitable for detecting low-to-medium dose nuclear radiation, while the high-range GM tube detector 32 is suitable for detecting high-dose nuclear radiation. Together, they achieve wide-range nuclear radiation coverage. The non-obstructing layout avoids signal interference between detectors, ensuring the accuracy and independence of their respective detection signals. This allows the control components to receive and process the two effective signals separately, improving the overall accuracy and reliability of nuclear radiation detection.

[0042] like Figure 2 , 5 As shown, the control component 4 includes a preamplifier 41, a GM tube control board (not shown in the figure), a digital multiplexer 42, and a communication and power supply adapter board 43; the GM tube control board is connected to the high-range GM tube detector 32, the preamplifier 41 is connected to the scintillator detector 31, the digital multiplexer 42 is connected to both the GM tube control board and the preamplifier 41, and the communication and power supply adapter board 43 is connected to the digital multiplexer 42.

[0043] Specifically, the control component 4 includes a preamplifier 41, a GM tube control board, a digital multichannel 42, and a communication and power supply adapter board 43. The GM tube control board is connected to the high-range GM tube detector 32, providing high voltage to ensure its normal operation and acquiring the signals generated by the high-range GM tube detector 32. After processing, the signals are transmitted to the digital multichannel 42. The preamplifier 41 is connected to the scintillator detector 31, driving the scintillator detector 31 to operate, acquiring the signals generated by the scintillator detector 31, performing preliminary processing, and then transmitting them to the digital multichannel 42. The digital multichannel 42 is connected to both the GM tube control board and the preamplifier 41, controlling the entire detection system, processing signals from the GM tube control board and the preamplifier 41, and summarizing all signals before transmitting the summarized signal to the communication and power supply adapter board 43. The communication and power supply adapter board 43 is connected to the digital multichannel 42, transmitting the received summarized signal to the UAV.

[0044] like Figure 2 , 5As shown, the component support frame 2 is made of 3D printing material. The component support frame 2 is provided with mounting positions for fixing the detection component 3 and the control component 4. The detection component 3 and the control component 4 are mounted on the mounting positions by bolt assembly or interference fit.

[0045] Specifically, by using 3D printing materials to fabricate the component support frame 2, the mounting positions can be precisely customized according to the structural characteristics of the detection component 3 and the control component 4, achieving a compact layout of each component and improving space utilization. Simultaneously, the 3D printing process can flexibly manufacture complex structures, reducing the processing difficulty and cost of the component support frame 2. The detection component 3 and the control component 4 are mounted on the preset mounting positions using bolt assemblies or interference fits, balancing structural stability and ease of maintenance.

[0046] This utility model discloses a nuclear detection drone payload module. When the payload module needs to be installed on the drone host, the positioning component on the connecting surface of the housing 1 is aligned with the corresponding positioning structure on the drone host to initially position the module. Then, the locking component is operated to tightly lock the housing 1 and the drone host, ensuring a secure connection. At this time, the quick-connect electrical component on the housing 1 smoothly connects with the electrical interface of the drone host, establishing a power supply path and a signal transmission path. After the drone host starts up, it supplies power to the payload module through the quick-connect electrical component, and the module begins to operate. The detection component 3 starts under electric drive and detects nuclear radiation in the surrounding environment. Different detection components 3, based on their own characteristics, capture different ranges or types of nuclear radiation and convert the detected nuclear radiation information into corresponding electrical signals, i.e., detection signals, which are transmitted to the control component 4 through the connection line. After receiving the signal, the control component 4 processes the signal according to a preset program and algorithm, including signal amplification, filtering, and analysis, converting the original detection signal into meaningful nuclear radiation data information. After processing, control component 4 transmits this data information to the UAV host via quick-connect electrical components. The UAV host then transmits the data to the ground control system, thus completing the entire process of nuclear radiation detection signal acquisition, processing, and transmission. In this application, by setting up a quick-connect structure 5, where the positioning component ensures the precise positioning of the housing 1 and the UAV host during docking, the locking component ensures the stability of the connection, and the quick-connect electrical components enable rapid power and signal connection, the three work together to not only achieve rapid docking between the housing 1 and the UAV host but also ensure docking quality, greatly improving the efficiency of module installation and replacement, and enabling the UAV to quickly switch mission states. By setting up a component support frame 2 inside the housing 1, the detection component 3 and control component 4 are centrally installed on it, giving each component a fixed installation position, facilitating later inspection, repair, and maintenance of the module, and also improving the utilization of internal space, making the overall structure more compact. By setting up control component 4 and detection component 3, the validity and accuracy of the detection data are ensured, and the processed data is quickly transmitted to the UAV host via quick-connect electrical components, achieving efficient transmission of detection data and providing timely data support for subsequent analysis and decision-making.
