[0031] 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.

[0032] Example

[0033] Please see Figure 1 This utility model provides a vehicle-mounted integrated nuclear and chemical gas detector, including a nuclear radiation detection module 1, a chemical gas detection module 2, and a central control and processing module 3, as well as a device housing 4. The nuclear radiation detection module 1, the chemical gas detection module 2, and the central control and processing module 3 are integrated and disposed within the device housing 4, and the nuclear radiation detection module 1 and the chemical gas detection module 2 are both connected to the central control and processing module 3. A quick-change interface 5 is provided on the side of the device housing 4, and a quick-change connection part and a sealing part are provided between the quick-change interface 5 and the device housing 4.

[0034] This embodiment provides a vehicle-mounted integrated nuclear and chemical gas detector, which can achieve integrated detection of both nuclear radiation and chemical gases. Through modular disassembly and overall control coordination, it enables simultaneous acquisition and analysis of nuclear radiation and chemical gases. The overall control processing module 3 receives nuclear radiation data and chemical gas data and performs unified data processing, achieving efficient and integrated monitoring of nuclear and chemical substances. Furthermore, this embodiment features a quick-change interface 5 on the side of the device housing 4, allowing for the replaceability of internal modules and facilitating maintenance and replacement. Simultaneously, by integrating the various detection modules, the size is significantly reduced and power consumption lowered, making it more suitable for portable applications. Integrated collaborative monitoring avoids the limitations of single detection methods, improving the efficiency and comprehensiveness of early warning in hazardous scenarios.

[0035] In this embodiment, as Figure 1As shown, the equipment housing 4 is located outside the detector equipment. The nuclear radiation detection module 1, the chemical gas detection module 2, and the overall control processing module 3 are all integrated and located inside the equipment housing 4. The equipment housing 4 is also equipped with support components for supporting each module and electronic components for connecting each module. The equipment housing 4 is used to support the internal modules and also plays a protective role, isolating dust, water vapor, impact and other external environmental factors, and protecting the internal precision electronic components and other parts from damage.

[0036] Specifically, the detection modules are highly integrated and arranged in a partitioned layout inside the equipment housing 4. The nuclear radiation detection module 1 is located in the front area inside the equipment housing 4, while the chemical gas detection module 2 and the central control and processing module 3 are located in the rear area inside the equipment housing 4, with the central control and processing module 3 positioned above the chemical gas detection module 2. The central control and processing module 3 is "proximity-based" with each module, shortening signal transmission paths, simplifying wiring, and saving overall equipment space. Furthermore, this embodiment optimizes the overall equipment structure through a partitioned layout, resulting in a compact layout, orderly arrangement of components, and stable connections, thus avoiding detection interference between modules.

[0037] Furthermore, in this embodiment, the device housing 4 includes an upper cover 41 and a bottom cover 42. The upper cover 41 is disposed at the upper end of the bottom cover 42, and the upper cover 41 and the bottom cover 42 are connected by a press-fit method. A sealing groove and a reinforcing connector are provided at the splicing position of the upper cover 41 and the bottom cover 42, and a sealing element is adapted to be connected in the sealing groove.

[0038] Specifically, such as Figure 1 As shown, the equipment cover 41 and the equipment bottom shell 42 are provided with opposing sealing grooves at their junction. The sealing element connected in the sealing groove is a sealing strip. The reinforcing connector is provided with connecting screws. The equipment cover 41 and the equipment bottom shell 42 are provided with matching connecting hole mounting holes, and the connecting screws are set in the connecting hole mounting holes. The entire equipment is spliced ​​by a sealing groove + sealing strip pressing method, and the connection is reinforced by connecting screws. The preload of the connecting screws is ≥700N, and the connection seal can withstand a pressure greater than 10KPa.

[0039] In this embodiment, the equipment housing 4 adopts a press-fit method, which has high assembly efficiency and facilitates subsequent disassembly and maintenance. Sealing components such as rubber strips and silicone gaskets can be installed in the sealing groove to prevent external dust, moisture, liquids, etc. from entering the equipment, thereby improving the dustproof and waterproof performance of the housing and protecting the internal components from environmental influences. In addition, additional connecting parts are provided, which can be adapted to screws, bolts, rivets, etc. The specific number of these parts can be adjusted according to actual usage needs. Mechanical fastening further strengthens the connection between the upper and lower housings, improving the stability of the equipment in complex scenarios.

[0040] Furthermore, in this embodiment, as Figure 2 As shown, the device housing 4 is connected to a power interface 6, a communication interface 7, and signal indicator lights. The power interface 6 is used to connect to an external power source to provide the power required for the operation of the internal components of the device. The communication interface 7 is the channel for the central control processing module 3 to exchange data with external devices / systems, enabling the device to connect with computers, servers, and other terminals for data transmission. The signal indicator lights serve as a "visual feedback window" for the device's operating status. Multiple signal indicator lights are provided, and different signal indicator lights can display the working status, faults, and nuclear and chemical early warning lights. Different device working information is conveyed through different colors (such as red, green, and yellow) and flashing modes (constant light, fast flashing, and slow flashing), which can help users quickly determine the current working status of the detector without disassembling or connecting other devices for inspection.

[0041] Furthermore, as a preferred embodiment of this utility model, the vehicle-mounted nuclear and chemical integrated detector has a maximum size of 320*150*120mm and a maximum weight of ≤4.5kg. The device has an IP65 protection rating. The device is compact, portable, and easy to carry. It can be installed on a vehicle for portable vehicle use. It can also be used in scenarios with limited space, such as being held by a single person, placed in an emergency backpack, or installed on a small operating table. The device has a high protection rating and is suitable for rapid and automated detection in complex environments where there is nuclear radiation or chemical gas agents.

[0042] In this embodiment, the nuclear radiation detection module 1 includes a nuclear sampling module and a nuclear data output module, and the chemical gas detection module 2 includes a chemical gas sampling module, a gas analysis module, and a gas data output module. The central control and processing module 3 controls the startup and information acquisition of the nuclear radiation detection module 1 and the chemical gas detection module 2. The central control and processing module 3 is connected to a host computer. The central control and processing module 3 processes the signal data of the nuclear radiation detection module 1 and the chemical gas detection module 2 and communicates with the host computer through the communication interface 7 to transmit the data to the host computer, thereby realizing the effective acquisition, analysis, and uploading of nuclear radiation and chemical gas data in the environment.

[0043] Specifically, the nuclear radiation detection module 1 measures the environmental radiation value through the sampling module and the nuclear data output module, identifies the nuclides present in the environment, and outputs radiation characteristic data; the chemical gas detection module 2 works in conjunction with the chemical gas sampling module, the gas analysis module, and the gas data output module to collect chemical gases in the environment, analyze the gas composition, and output gas composition data, gas radioactivity data, etc.

[0044] The detection system in this embodiment adopts an integrated structural design, integrating the nuclear detector, chemical detector, and acquisition, control, and analysis circuits into the equipment housing. Each module acquires and measures the signals it is sensitive to, and outputs the corresponding electrical signals to the controller. The controller then aggregates the signals and outputs them to the host computer through an external communication interface, realizing efficient and automated integrated nuclear and chemical detection.

[0045] In this embodiment, as Figure 3 , Figure 4 As shown, the chemical gas detection module 2 is equipped with a filter unit, which has a filter element 21. The filter element 21 can dry the gas in the internal gas path and absorb moisture. Since the internal gas path is connected to the outside before it is formed, this part of the gas needs to be fully filtered and dried by the filter element under the drive of the power unit before it can enter the internal gas path for analysis by other modules.

[0046] Specifically, filter element 21 adopts a replaceable structure and is located close to quick-change interface 5. Quick-change interface 5 allows for rapid replacement of filter element 21 without disassembling the module. Since filter elements gradually age and fail during detector use, reducing the detection efficiency of the internal system, existing modular designs have high integration, with filter elements integrated inside the device, making replacement complex. This embodiment, however, utilizes quick-change interface 5 to facilitate convenient replacement of filter element 21 within the module. When filter element 21 fails, it can be quickly replaced according to usage requirements, making the operation convenient.

[0047] like Figure 4 As shown, the filter unit is equipped with a filter element mounting base 22. The filter element 21 is detachably mounted on the filter element mounting base 22. The filter element 21 is horizontally positioned for easy pull-out replacement. Furthermore, the outer end of the filter element 21 is equipped with a screw quick-release knob 23, which is located inside the quick-change interface 5 and opposite to it. The screw quick-release knob 23 is located at the end of the non-working area of ​​the filter element 21, without affecting the normal operation of the internal integrated module. By rotating the screw quick-release knob 23, the connection between the filter element 21 and the mounting base can be released, allowing for convenient replacement without the need for traditional tools. This makes disassembly and assembly efficient and maintenance convenient.

[0048] In this embodiment, the quick-change interface 5 is a window-type cover structure opened on the side of the equipment housing 4. The quick-change interface 5 has a square structure and its opening size is larger than the maximum outer diameter of the filter element. The quick-change interface 5 is sealed and fitted to the equipment housing 4 through the quick-change connection part and the sealing part. When it is necessary to replace the internal filter element, the quick-change interface 5 can be removed to easily replace the filter element. The equipment has high reliability.

[0049] Specifically, such as Figure 3 , Figure 5As shown, the quick-change connection includes a connecting protrusion 43 and a sealing groove 51 adapted to the connecting protrusion 43. The connecting protrusion 43 and the sealing groove 51 are located at the contact position between the quick-change interface 5 and the equipment housing 4. The connecting protrusion 43 is located on the equipment housing 4, and the sealing groove 51 is located on the inner side of the quick-change interface 5. The connecting protrusion 43 is an annular protrusion structure, and the sealing groove 51 is an annular groove structure adapted to the annular protrusion. The quick-change interface 5 and the equipment housing 4 are conveniently connected by the engaging connection of the connecting protrusion 43 and the sealing groove 51. The sealing part is provided with an annular sealing strip, which is located in the sealing groove 51. The sealing strip ensures the stability and sealing of the quick-change interface 5 and the equipment housing 4 during the pressing.

[0050] Furthermore, the quick-change connection also includes reinforcing screws. Both the quick-change interface 5 and the equipment housing 4 have four screw mounting holes, located at the four corners of the quick-change interface 5. The reinforcing screws are installed in these screw mounting holes. The reinforcing screws work independently of and cooperate with the connecting protrusion and sealing groove connection structure. When the connection between the connecting protrusion 43 and the sealing groove 51 fails due to an accident, the reinforcing screws ensure the stability of the connection between the quick-change interface and the equipment housing. Moreover, the physical connection between the reinforcing screws and the equipment housing strengthens the structural strength of the connection, preventing loosening of the connection due to stress (such as vibration or load) during use.

[0051] Furthermore, as a preferred embodiment, such as Figure 3 , Figure 5 As shown, the quick-change interface 5 is provided with a positioning part, which is a hemispherical positioning protrusion 52 located at both ends of the inner side of the quick-change interface 5. There are two positioning protrusions 52. The corresponding hemispherical positioning grooves 44 are provided on the side of the equipment housing 4 to match the hemispherical positioning protrusions 52. Through the matching connection between the positioning protrusions 52 and the positioning grooves 44, the accuracy and stability of the quick-change interface 5 during docking are ensured, and the connection between the quick-change interface 5 and the equipment housing 4 is made precise and efficient, thereby improving installation efficiency and avoiding installation misalignment.

[0052] Furthermore, as a preferred embodiment, such as Figure 5 , Figure 6 As shown, the quick-change interface 5 is provided with a quick-change grip 53. The quick-change grip 53 is a concave arc-shaped grip groove structure set on both sides of the quick-change interface 5. By setting the grip groove, the operation difficulty of disassembling and assembling the quick-change interface 5 is reduced, the replacement efficiency is improved, and the individual can carry out the operation with one hand, making it convenient for staff to hold and replace the internal filter element.

[0053] Furthermore, as a preferred embodiment, the arrangement of the connecting protrusion 43 and the sealing groove 51 is not limited to a fixed shape, and its setting position can be adjusted according to actual needs. The sealing groove can be set on the equipment housing, and the connecting protrusion can be adapted to be set on the inner side of the quick-change interface. The positioning part can be set as a protrusion, groove, pin hole or guide structure, and the setting shape, size and specific number of the positioning part can also be adapted and adjusted according to the actual situation.

[0054] Furthermore, in this embodiment, as Figure 7 As shown, the gas path within the chemical gas detection module 2 includes an internal gas path and an external gas path. The chemical gas sampling module includes an inlet 24 and an outlet 25, which are connected to the external gas path. A gas guide pipe is connected to the inlet 24 and outlet 25, allowing chemical gas to enter / exit from the front of the device through the gas guide pipe. The external gas path is circulated via an intake drive unit, which can be a pump or similar structure. The inlet 24 and outlet 25 are located within a semi-recessed structure on the side of the device housing 4. This semi-recessed structure prevents direct impact from the outside environment and reduces the direct splashing of dust and water droplets into the gas outlet.

[0055] Specifically, the internal gas path is connected to the gas analysis module, which includes an ion separation unit and an ion detection unit. The ion separation unit includes an ion exchange membrane, and the ion detection unit includes an ion migration tube. The ion exchange membrane is the starting point of the internal gas path. A drive unit that provides gas flow power is connected to the ion migration tube. A filter unit is connected to the drive unit. The gas data output module is connected to the central control and processing module.

[0056] Under the action of the driving unit, ambient gas passes through the gas tube from one side of the ion exchange membrane. The gas cannot pass through the ion exchange membrane; it only exchanges ions with the gas inside. The ion exchange membrane has an internal gas exchange side and an external gas exchange side, enabling bidirectional exchange of "external ions entering the membrane and internal ions transferring to the outside." External gas passes through the external gas exchange side; the gas itself cannot permeate the membrane, only the exchange ions carried by the gas are allowed to pass, while gas molecules are prohibited from passing. Ions can migrate through ion exchange sites on the membrane. The ion migration tube is connected to the outlet of the ion exchange membrane. After the external ambient gas passes through the ion exchange membrane and exchanges ions with the internal gas, ions carrying information about the environmental chemical gases flow into the ion migration tube and are absorbed by the ion migration tube. Since different chemical gases correspond to different electrical signals, the ion migration tube can output corresponding electrical signals.

[0057] In this implementation, the external gas path is connected to the external environment and serves as the gas path for the chemical gas sampling module. The external gas path acts as a "connection channel" between the module and the external environment, enabling the collection and circulation of ambient air. The internal gas path is the gas path for the gas analysis module. The internal gas path is connected to the external gas path through the ion separation unit. The internal gas path forms an internal circulating sealed system, which is not directly connected to the outside, thus avoiding interference from external air with the analysis results and ensuring the accuracy of the internal gas path analysis.

[0058] In this embodiment, the chemical gas detection module 2 has a high degree of integration, integrating scattered gas pipelines. Through modular design and integrated gas circuit board structure, it reduces exposed pipelines and independent connection points, resulting in a more compact structure.

[0059] Furthermore, a filter section is connected to the air inlet 24 and / or the exhaust port 25. The filter section includes a dustproof sponge and a hydrophobic filter screen. The dustproof sponge is disposed outside the hydrophobic filter screen. The dustproof sponge is a dustproof sponge with a density of 60 PPI, and the hydrophobic filter screen is a hydrophobic melt-blown filter screen.

[0060] The filter section in this embodiment may include at least one of a dustproof sponge and a hydrophobic meltblown filter. The specific specifications and structure of the filter unit can also be adapted and adjusted according to the actual working conditions and usage environment.

[0061] Furthermore, such as Figure 7 , Figure 8 As shown, the outer end of the air inlet 24 and / or the exhaust port 25 is provided with a quick-connect pneumatic interface 8. The outer wall of the quick-connect pneumatic interface 8 is stepped and raised, and the outer end of the quick-connect pneumatic interface 8 is connected to a rain cover 9.

[0062] Specifically, the quick-connect pneumatic interface 8 is a universal 4mm outer diameter pagoda-shaped pneumatic interface. Installation requires no complex threading; simply slip the hose directly onto it. The raised structure secures the hose to the inner wall, preventing it from falling off. It is easy to install and remove, and allows for quick connection to the sample gas path. The rain cover 9 is a cylindrical rain cover structure. When sampling ambient air samples, the rain cover prevents the entry of environmental dust and moisture, avoiding contamination of internal structures such as the ion migration tube. It also has ventilation gaps to ensure normal airflow. This embodiment, through multi-layered protection of "external rain protection + internal dust and water repellency," ensures normal gas collection while avoiding interference from the external environment.

[0063] Furthermore, in this embodiment, the external connector of the device uses a Lingke aviation plug, which can achieve an IP67 sealing rating when connected, resulting in a more stable and durable circuit connection with strong sealing performance.

[0064] This invention provides a vehicle-mounted integrated nuclear and chemical gas detector, which can achieve integrated detection of both nuclear radiation and chemical gases. Through modular disassembly and overall control coordination, it enables simultaneous acquisition and analysis of nuclear radiation and chemical gases. The overall control processing module 3 receives nuclear radiation data and chemical gas data and performs unified data processing, achieving efficient and integrated monitoring of nuclear and chemical substances. Furthermore, this embodiment features a quick-change interface 5 on the side of the device housing, allowing for the replacement of the internal filter element 21, facilitating maintenance and replacement. Simultaneously, by integrating the various detection modules, the size is significantly reduced and power consumption lowered, making it more suitable for portable applications. Integrated collaborative monitoring avoids the limitations of single detection methods, improving the efficiency and comprehensiveness of early warning in hazardous scenarios.

[0065] This invention breaks through the traditional model of separate assembly and monitoring of various detection modules in detectors, achieving miniaturization and high integration. This reduces power consumption while improving stability, enabling not only vehicle-mounted installation but also compatibility with portable devices or standardized monitoring station scenarios. By featuring an open quick-release interface, the filter element becomes an independent, separable component, facilitating easy filter replacement. The quick-release interface ensures secure installation and convenient disassembly. Through its integrated design, the detector simultaneously acquires and analyzes nuclear radiation and chemical gas signals via nuclear radiation detection and chemical gas detection modules. A central control processing module handles signal reception, unified processing, and alarm triggering.
