Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detection devices, in particular to a modular detection device for detecting components and elements. BACKGROUND

[0002] In the field of environmental safety monitoring, especially in the complex environment of closed spaces such as deep wells and mine tunnels, real-time and accurate concentration monitoring of multiple harmful gases is often required, such as real-time monitoring of hydrogen sulfide, carbon monoxide, methane, etc. to ensure safety. Such detection tasks usually rely on integrated gas sensing devices, which convert gas concentration signals into readable electrical signals through electrochemical or other sensitive units. Existing devices mostly use fixed single-point probes or split main units combined with probe structures, which are powered and transmit data through cables.

[0003] In existing deep well detection scenarios, the operator needs to lower the probe to the designated location for local gas sampling. Although such designs can achieve basic detection of specific gases in regular environments, they have strong structural rigidity and the sensing unit mostly relies on a single detection end to output data, making it difficult to adapt to dynamic variables such as temperature and humidity fluctuations, airflow disturbances, or multi-component gas cross-interference in deep space. Especially when the sensor's own working medium, such as electrolyte, optical window, or filter membrane, experiences performance degradation due to environmental changes, if only relying on single-point data without a collaborative calibration mechanism, the system cannot distinguish whether the signal anomaly is caused by changes in environmental gas concentration or degradation of the sensor's own electrolyte.

[0004] In high-humidity and high-temperature environments such as deep wells, electrochemical gas sensors based on water-based electrolytes often face the problem of continuous evaporation of electrolyte solvent. To maintain stability, existing technologies mostly use reinforced sealed housings or add buffer layers to slow down evaporation. However, the sealed structure hinders gas diffusion efficiency, and passive protection cannot dynamically compensate for solvent loss, which can lead to uncertainty and increase the false alarm rate, or even mislead safety decisions due to continuous false data.

DETAILED DESCRIPTION

[0043] The modular detection device for detecting components and elements provided by the present application is described in detail below in combination with the drawings and specific embodiments. It is noted here that the following embodiments are the best, preferred embodiments, and other alternative embodiments can also be implemented by those skilled in the art for some known technologies; and the drawings are only used to more specifically describe the embodiments, and are not intended to specifically limit the present application.

[0044] As shown in Figures 1 to 9 The present embodiment provides a modular detection device for detecting components and elements, which comprises a conical cavity sleeve 1, a circular ring type partition plate 3 is fixedly connected at the middle position of the inside of the conical cavity sleeve 1, and the inner cavity of the conical cavity sleeve 1 is divided into a front cavity and a rear cavity by the circular ring type partition plate 3;

[0045] The front cavity is provided with a liquid supplementing mechanism 10 for storing electrolyte and a gas guiding mechanism 6, and a signal feedback disc 7 is arranged on the surface of the liquid supplementing mechanism 10, and the surface of the signal feedback disc 7 is circumferentially arranged with a plurality of modular detection units 9 which constitute real-time comparison detection groups;

[0046] The rear cavity is provided with a recovery mechanism 5, and the recovery mechanism 5 is provided with a plurality of adsorption cylinders 55 for adsorbing impurities to supply oxygen again;

[0047] The gas guiding mechanism 6 adsorbs the surrounding gas into the front cavity, so that the adsorbed gas covers the detection end of each modular detection unit 9, the signal feedback disc 7 cross- verifies the current change of the detection end of each modular detection unit 9, obtains the real change of the environmental gas concentration and the sensor performance attenuation data, and supplies oxygen and electrolyte in time to stabilize the working environment of the electrode in the modular detection unit 9.

[0048] To solve the problems of high false alarm rate and inability to distinguish between real changes in environmental gas concentration and sensor performance degradation in the prior art when detecting gas in airtight and complex environments such as deep wells and mines, the above technical solution is used to solve the problem. The above technical solution mainly consists of a conical cavity sleeve 1, a circular ring type partition plate 3, a liquid supplementing mechanism 10, a signal feedback disc 7, a modular detection unit 9, a gas guiding mechanism 6, and a recovery mechanism 5, etc. The detection accuracy and stability are improved through the cross-validation and dynamic compensation mechanism of the modular detection unit 9. The conical cavity sleeve 1 is made of polycarbonate engineering plastic, and is conical in shape, which helps to guide the airflow to optimize the gas flow path and avoid local vortex interference detection, and also reduces dust accumulation. The liquid supplementing mechanism 10 includes a conical circular cavity sleeve 101 made of polytetrafluoroethylene corrosion-resistant material, which stores electrolyte of the same origin as the modular detection unit 9 in the internal cavity. The signal feedback disc 7 is a printed circuit board structure for electrically connecting the modular detection unit 9, and is circular in shape, which allows multiple modular detection units 9 to work synchronously and facilitates the passage of gas from the center of the ring. Multiple modular detection units 9 are provided to provide signal cross-validation to eliminate single-point errors and improve the reliability of the overall data of the detection end. The cavity disc cover 51 of the recovery mechanism 5 is filled with molecular sieve and activated carbon material to adsorb impurities in the gas and enrich oxygen, achieving cyclic purification and oxygen reuse of the gas and maintaining the stability of the electrode working environment.

[0049] As a whole, the surrounding gas is absorbed into the front cavity through the gas guiding mechanism 6, covering the detection end of each modular detection unit 9. The signal feedback disc 7 cross- validates the current change of the detection end of each modular detection unit 9 to obtain real changes in environmental gas concentration and sensor performance degradation data, to supply oxygen and electrolyte in time to stabilize the working environment of the electrodes in the modular detection unit 9, solve the drift problem of the sensor in harsh environments, and enhance the applicability of the detection end of the detection device in specific environments.

[0050] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the liquid supplement mechanism 10 comprises a tapered annular cavity sleeve 101, which is an overall inwardly recessed annular cavity structure, and is fixedly connected with a heat conduction plate 102 at the side end of the tapered annular cavity sleeve 101, the heat conduction plate 102 is overall arranged on the front side of the annular partition plate 3, and the surface of the heat conduction plate 102 is circumferentially connected with a plurality of assembly sleeves 103 corresponding to the modular detection units 9 one by one, the assembly sleeves 103 are all connected with heat conduction metal pipes 104, the heat conduction metal pipes 104 all horizontally extend to one end of the modular detection units 9 one by one, and the extending ends are all fixedly connected with cover sleeves 105, and the inner wall of the cover sleeves 105 is fixedly connected with a plurality of heat conduction wires 106.

[0051] The ring cavity inside the configured conical annular cavity sleeve 101 is used to store electrolyte homologous to the modular detection unit 9, and its volume is preset according to the number of modular detection units 9 to ensure the supply of electrolyte during long-term detection. The configured heat conduction plate 102 is made of metal materials with high thermal conductivity, including but not limited to copper alloy, and its plate-shaped structure is fixed to the narrow end of the conical annular cavity sleeve 101 by hot pressing. The heat conduction plate 102 is located on the front side surface of the annular partition plate 3, realizing heat transfer. On the one hand, the annular partition plate 3 serves as a component to separate the front and rear cavities, and heat may be generated when the air guiding mechanism 6 is working. The heat conduction plate 102 can quickly disperse the heat to avoid local overheating affecting the stability of the electrolyte. On the other hand, the heat conduction plate 102 stabilizes the temperature of the electrolyte in the conical annular cavity sleeve 101 by transferring heat, slows down the evaporation or condensation of electrolyte caused by environmental temperature fluctuations, and thus maintains the uniformity of electrolyte concentration. The surface of the heat conduction plate 102 is circumferentially connected with a plurality of assembly sleeves 103 corresponding to the modular detection units 9. The assembly sleeves 103 are made of insulating engineering plastics, and their tubular structures are fixed to the surface of the heat conduction plate 102 by buckling, arranged in a circumferential manner, and consistent with the distribution of the modular detection units 9 as a whole, ensuring that each modular detection unit 9 can obtain an independent electrolyte supply path. The assembly sleeve 103 not only serves as a mechanical support structure, but also forms an electrolyte flow channel by communicating with the conical annular cavity sleeve 101 through its internal cavity. The heat conduction metal pipe 104 is made of metal materials with good heat conductivity such as copper, and its pipe diameter is designed according to the demand of electrolyte flow rate. It extends horizontally in parallel with the axis of the modular detection unit 9, promoting the smooth delivery of electrolyte by capillary action. The heat conduction metal pipe 104 can be coated with a corrosion-resistant coating to resist electrolyte corrosion. Its heat conduction characteristics guide the heat of the detection cylinder 91 in each side cover sleeve 105 to one end of the heat conduction plate 102, so as to avoid the electrolyte in the detection cylinder 91 from being precipitated or deposited due to environmental temperature gradient. A plurality of heat conducting wires 106 are fixedly connected to the inner wall of the cover sleeve 105, which is also made of heat conducting metal and used to wrap and position the detection cylinder 91. The plurality of heat conducting wires 106 are woven from copper wire or aluminum wire and distributed in a radial manner on the outer wall of the detection cylinder 91 to increase the heat contact area. The heat conducting wires 106 stably transfer heat from one end of the detection cylinder 91 to the heat conduction plate 102 to stabilize the working temperature of the electrode area and prevent the activity of electrolyte from decreasing due to local low temperature.

[0052] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the surface of the signal feedback disc 7 is circumferentially fixedly mounted with a plurality of modular assembly interface sleeves 8, and the modular detection unit 9 comprises a plurality of detection barrels 91, each of which is assembled on the modular assembly interface sleeve 8 by inserting the outer cover sleeve 105, the outer wall of the detection barrel 91 corresponds to a plurality of heat-conducting wires 106, and the side wall of the detection barrel 91 and the outer cover sleeve 105 is provided with an opening for connecting the heat-conducting metal pipe 104, and the inside of each heat-conducting metal pipe 104 is provided with a capillary adsorption sleeve 107 to connect the conical annular cavity sleeve 101 and each detection barrel 91.

[0053] Among them, the surface of the signal feedback disc 7 is circumferentially fixedly mounted with a plurality of modular assembly interface sleeves 8, and the signal feedback disc 7 is preferably a multilayer printed circuit board structure made of glass fiber reinforced epoxy resin, and the surface thereof is formed with copper conductive tracks through a photoetching process. The modular assembly interface sleeve 8 is a phosphor bronze socket, which is arranged in a circumferential manner to ensure independent transmission of the electrical signal of each modular detection unit 9, avoid cross interference, and facilitate quick plug-in maintenance of the modular detection unit 9. The signal feedback disc 7 is integrated with an analog-to-digital converter chip in the prior art to realize real-time acquisition of current signals at each detection end and realize multi-channel data synchronous processing, thereby providing a hardware basis for cross verification. The detection barrel 91 is made of polytetrafluoroethylene, and the cylindrical structure thereof is fixedly arranged in the inner part of the outer cover sleeve 105 through interference fit, and the outer wall of the detection barrel 91 corresponds to a plurality of heat-conducting wires 106 to maximize the heat contact area. The side wall of the detection barrel 91 and the outer cover sleeve 105 is provided with an opening for connecting the heat-conducting metal pipe 104 to ensure smooth flow of the electrolyte. The inside of each heat-conducting metal pipe 104 is provided with a capillary adsorption sleeve 107 to connect the conical annular cavity sleeve 101 and each detection barrel 91. The capillary adsorption sleeve 107 is made of a porous hydrophilic material in the prior art, including but not limited to sintered glass fiber and silica gel porous tube, which is embedded in the inner cavity of the heat-conducting metal pipe 104. The capillary adsorption sleeve 107 continuously and uniformly transports the electrolyte from the liquid storage cavity of the conical annular cavity sleeve 101 to the electrode area of each detection barrel 91 through capillary action, without relying on external power, thereby avoiding the interference of pumping vibration on the detection signal. At the same time, the flow rate is controlled through the capillary diameter to ensure that the electrolyte supply and evaporation rate are matched, thereby improving the long-term stability of the modular detection unit 9 in a high-temperature and high-humidity environment. Moreover, the material of the capillary adsorption sleeve 107 also has chemical corrosion resistance to prolong the service life.

[0055] Among them, the butt joint pin group 97 is made of gold-plated copper alloy pins, which are fixed on the insulating base at the tail end of the detection cylinder 91 by crimping or welding, the number of pins matches the number of electrodes, and is used to conduct the electrical signals of the working electrodes 93, the counter electrode 94 and the reference electrode 95 to the signal feedback plate 7. The modular plug-in design facilitates independent replacement of individual modular detection units 9, reducing maintenance costs. The gas permeable film sleeve plate 92 is made of porous hydrophobic materials such as polytetrafluoroethylene, and its disc-shaped structure is fixed by heat pressing or gluing at the gas inlet end of the detection cylinder 91, which can allow gas molecules to diffuse freely into the detection cavity, and can block liquid water or dust particles to prevent electrode contamination. The working electrodes 93 are assembled near the gas permeable film sleeve plate 92, the working electrodes 93 are made of noble metal catalyst coated on a porous carbon-based carrier, and are fixed on the electrode support on the inner wall of the detection cylinder 91 by conductive silver glue, the position is close to the inside of the gas permeable film sleeve plate 92, so that the diffused gas molecules preferentially contact the surface of the working electrode 93 to produce an oxidation-reduction reaction, generating an electric current signal proportional to the gas concentration. The counter electrode 94 is made of platinum, which is used to form a current loop to balance the electrochemical reaction of the working electrode 93, and the reference electrode 95 is used to provide a stable potential reference, the polarization voltage of the working electrode 93 is controlled by the potential stability of the reference electrode 95, and the measurement error caused by the change of electrolyte concentration is reduced. The arc-shaped converging plate 96 is a U-shaped partition structure covering the outside of the reference electrode 95, which is made of chemically inert materials, the U-shaped cross section surrounds the active surface of the reference electrode 95, forming a semi-closed gas migration channel, guiding the subsequent supplemented oxygen to cover, thereby stabilizing the local electrolyte composition near the reference electrode 95, and further improving the long-term stability of the reference potential.

The circular ring type partition plate 3 is in the form of a ventilation leakage plate. The recovery mechanism 5 includes a cavity disc cover 51 attached to the rear side of the circular ring type partition plate 3. The side surface of the cavity disc cover 51 is fixedly connected with a magnetic type filter screen 52 to ensure the gas flow. The cavity disc cover 51 is in the form of a circular ring. The conical cavity sleeve 1 is fixedly installed with a servo motor 4 at the other side opposite to the detachable filter screen 2. The output end of the servo motor 4 penetrates into the inside of the conical cavity sleeve 1 through the center of the cavity disc cover 51.

[0057] The detachable filter screen 2 is made of stainless steel woven mesh, which allows uniform gas flow into the front cavity and intercepts large particles of dust, fibers and other impurities to avoid their adhesion to the surface of the ventilation film sleeve 92 of the modular detection unit 9, thereby ensuring the gas diffusion efficiency.

The circular ring type partition plate 3 is in the form of a ventilation leakage plate, and the plate body is made of aluminum alloy or engineering plastic. The surface is uniformly provided with ventilation holes to form a gas flow channel. The circular ring type partition plate 3 not only serves as a mechanical separation component between the front and rear cavities, but also guides the gas flow to smoothly transition from the front cavity to the rear cavity through the leakage hole structure to avoid vortex generation. Figure 1 As shown, when the gas flow passes through the circular ring type partition plate 3, the flow rate is slowed down due to the damping effect of the holes, so that part of the heavier impurities are settled at the bottom of the front cavity due to inertia, realizing secondary gravity filtration

In the working process, the recovery mechanism 5 and the air guide mechanism 6 work cooperatively, the airflow is pressurized and delivered to the adsorption cylinder 55 area by the circular ring cylinder type adsorption fan 61 after multi-stage filtration, the impurities are further adsorbed by the molecular sieve and activated carbon in the adsorption cylinder 55, and the oxygen is enriched on one side of the center of the cavity disc cover 51 through the first gas permeation hole 54 and the second gas permeation hole 64, and finally is supplied to the reference electrode 95 area of the detection cylinder 91 through the quick-release delivery pipe 11, which prolongs the service life of the filter material on one hand, and reduces the dependence on the external gas source on the other hand through oxygen recirculation, and significantly improves the adaptability of the device in the oxygen-deficient environment.

[0060] As shown in Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 1 , a plurality of first gas permeation holes 54 are arranged on the inner circular ring side of the circular ring storage cavity 53 in a circumferential manner, a plurality of second gas permeation holes 64 are arranged on the cylinder wall of the circular ring cylinder type adsorption fan 61 in a circumferential manner, a preset insertion cylinder 63 is fixedly connected to the center end of the conical fan block 62, a cavity heat conduction cylinder 56 is inserted into the inside of the preset insertion cylinder 63, a cylinder type adsorption pump 57 is fixedly installed on one end of the cavity heat conduction cylinder 56 facing the circular ring cylinder type adsorption fan 61, and the adsorption end of the cylinder type adsorption pump 57 is attached to the inner circular ring side wall of the circular ring cylinder type adsorption fan 61.

[0061] As shown in Figure 2 ,Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 1 As shown in the drawings, the inside of the cavity heat conducting cylinder 56 is hollow to transport the gas adsorbed by the cylindrical adsorption pump 57, and the side of the cavity heat conducting cylinder 56 away from the cylindrical adsorption pump 57 is circumferentially assembled with an external delivery hose 58 corresponding to the modular detection unit 9, and the outer side of each external delivery hose 58 is provided with a quick-release delivery pipe 11, and the side wall of the detection cylinder 91 at the position of the reference electrode 95 is provided with an external access sleeve 98, and the quick-release delivery pipe 11 is connected to the external access sleeve 98 to supply oxygen.

[0062] The cavity heat conducting cylinder 56 is made of a metal material with good heat conductivity, and the internal cavity forms a low-resistance gas channel. When the cylindrical adsorption pump 57 is started, the negative pressure generated by the cylindrical adsorption pump 57 actively sucks the oxygen enriched in the central region of the circular ring cylinder adsorption fan 61 into the cavity of the cavity heat conducting cylinder 56 for transportation. The metal material of the cavity heat conducting cylinder 56 simultaneously plays a heat conducting role, and can quickly dissipate the heat generated during the gas transportation process, avoiding chemical property changes of the oxygen due to local heating. The external delivery hose 58 is made of corrosion-resistant fluororubber material and a magnetic sleeve. The quick-release delivery pipe 11 is a component for connecting the external delivery hose 58 and the detection cylinder 91, and the two ends thereof are quickly connected and separated through the magnetic sleeve ring 112, facilitating the maintenance and replacement of a single detection end without the need to disassemble the entire gas delivery system. The external access sleeve 98 is made of stainless steel engineering plastic, and the inner diameter of the interface thereof matches the conical gas collecting head 113 of the quick-release delivery pipe 11. The position of the external access sleeve 98 is opposite to the opening of the arc converging plate 96 of the reference electrode 95, ensuring that the oxygen can directly cover the surface of the reference electrode 95. The oxygen is supplied through the quick-release delivery pipe 11 connected to the external access sleeve 98. The gas delivery hose 111 of the quick-release delivery pipe 11 is made of flexible rubber. When the oxygen is delivered to the quick-release delivery pipe 11 through the external delivery hose 58, the tapered structure of the conical gas collecting head 113 focuses the airflow, improving the concentration of the oxygen delivery. Finally, the oxygen enters the inside of the detection cylinder 91 through the external access sleeve 98, uniformly covers the area of the reference electrode 95 under the guidance of the arc converging plate 96, and maintains the stability of the electrode potential. In the working process, the oxygen delivery path forms a complete closed loop, that is, the oxygen enriched and purified by the adsorption cylinder 55 flows to the central region of the circular ring cylinder adsorption fan 61 through the first gas permeable hole 54 and the second gas permeable hole 64, and the oxygen is actively extracted by the cylindrical adsorption pump 57 into the cavity heat conducting cylinder 56. The oxygen is distributed to each external delivery hose 58 through the cavity heat conducting cylinder 56, and the quick-release delivery pipe 11 delivers the oxygen to the external access sleeve 98 of the detection cylinder 91, so that the oxygen finally covers the surface of the reference electrode 95.

[0064] As Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , ​ As shown in

[0065] The gas conveying hose 111 is made of fluororubber flexible corrosion-resistant material, has good air tightness and anti-aging properties, and the length of the hose is pre-set according to the spacing of the modular detection unit 9, allowing the hose to be arranged in a bent manner inside the device, adapting to different installation space requirements, absorbing vibrations through its flexible design, and avoiding connection loosening caused by airflow pulses or equipment shaking. The magnetic suction end of the magnetic suction collar 112 is composed of a neodymium-iron-boron permanent magnet and a stainless steel shell, which is fitted on both ends of the gas conveying hose 111 through interference fit. The ring-shaped structure of the magnetic suction collar 112 has a sealing ring embedded in it to ensure tight connection when the interface is connected. The outlet end of the external conveying hose 58 and the inlet end of the external access port sleeve 98 are both provided with a metal ring that matches the magnetic suction collar 112, and the quick connection is achieved through magnetic attraction. The conical gas collecting head 113 has a tapered conical shape, with the inlet diameter being larger than the outlet diameter. It is fixed to the end of the gas conveying hose 111 through threads, can focus the airflow, improve the concentration and flow rate of oxygen delivery, and ensure accurate coverage of the surface of the reference electrode 95. When oxygen is delivered to the quick-release conveying pipe 11 through the external conveying hose 58, the magnetic suction collar 112 automatically attracts and connects through magnetic force, the conical gas collecting head 113 is inserted into the conical interface of the external access port sleeve 98, forming multiple seals, and the oxygen accelerates through the tapered channel of the conical gas collecting head 113 and then stably enters the reference electrode 95 area of the detection cylinder 91, uniformly diffuses around the reference electrode 95 under the guidance of the arc-shaped converging plate 96, and maintains the stability of the electrode potential. When it is necessary to replace or maintain a certain modular detection unit 9, the magnetic suction collar 112 can be separated by hand, disconnecting the pipeline and avoiding affecting the normal work of other units. As the connection end on the other side, the heat-conducting metal pipe 104 only needs to pull out the internal capillary adsorption sleeve 107.

[0066] The use method provided by the application is as follows:

[0067] In use, first, based on each detection cylinder 91 on the modular detection unit 9, the gas in the deep well environment is detected in real time, when the data of a single group of detection cylinders 91 fluctuates obviously, the air guide mechanism 6 is started by the servo motor 4, the servo motor 4 is fixed at the tail end of the conical cavity sleeve 1, the output end penetrates into the inside through the center of the cavity disc cover 51, drives the circular ring cylinder adsorption fan 61 to rotate, and the surrounding environment gas is adsorbed to enter the front cavity of the conical cavity sleeve 1 through the detachable filter screen disc 2. After the external gas is filtered by the detachable filter screen disc 2, the gas flows into the front cavity, and then passes through the air leakage plate structure of the circular ring type partition plate 3, so that part of the relatively heavy particles are deposited at the bottom of the front cavity due to inertia, realizing secondary gravity filtration, and at the same time, after the gas is filtered by the magnetic filter screen disc 52 on the side of the cavity disc cover 51 attached to the rear side of the circular ring type partition plate 3, the organic vapor and other trace interference components are adsorbed, the circular ring storage cavity 53 in the cavity disc cover 51 further adsorbs impurities through the adsorption cylinder 55 on the outer edge to select oxygen. The conical fan block 62 fixed on one side of the circular ring cylinder adsorption fan 61 towards the detachable filter screen disc 2 is located in the notch of the conical circular ring cavity sleeve 101, guides the concentrated flow of air flow, avoids vortex interference, and at this stage, the gas covers the detection end of each modular detection unit 9, avoiding excessive air extraction leading to sensor overload.

[0068] Then, the inhaled gas diffuses to the detection end of the modular detection unit 9, and the current change of each modular detection unit 9 is cross-verified in real time by the signal feedback disc 7, in the detection cylinder 91, the working electrode 93 is close to the inner side of the gas permeable film sleeve disc 92, the oxidation-reduction reaction occurs, the current signal proportional to the gas concentration is generated, the counter electrode 94 and the reference electrode 95 form a loop, the arc-shaped converging plate 96 of the reference electrode 95 outer cover guides the air flow to stably cover the electrode surface, the signal feedback disc 7 collects the current data of each detection cylinder 91 by the butt pin group 97, and uses the built-in analog-to-digital converter for multi-channel synchronous processing. When the environmental gas concentration changes or the sensor performance decays, such as electrolyte evaporation, the output currents of different modular detection units 9 present differences, by comparing the data with each other, the system distinguishes the real concentration fluctuation from the sensor drift, if most units detect that the concentration rises, but a unit outputs abnormally, it is judged that the performance of the unit decays, a compensation mechanism is triggered to eliminate single-point error and improve data reliability, especially suitable for variable interference in deep space such as temperature and humidity fluctuation.

[0069] Then, the system starts the oxygen and electrolyte supply mechanism in time based on the cross-validation results to stabilize the electrode working environment. The cylindrical adsorption pump 57 adsorbs the oxygen enriched in the annular storage cavity 53 through the pre-insertion cylinder 63 and the cavity heat conduction cylinder 56, and the oxygen is transported to the external delivery hose 58 through the cavity heat conduction cylinder 56, and then connected to the external access port sleeve 98 of the detection cylinder 91 through the quick-release delivery pipe 11. At the same time, the liquid supplementing mechanism 10 supplies electrolyte, the conical annular cavity sleeve 101 stores electrolyte, and the electrolyte is transported to each detection cylinder 91 through the capillary adsorption sleeve 107 and the heat conduction metal pipe 104, and the heat conduction plate 102 is attached to the annular partition plate 3, and the temperature is adjusted through the heat conduction wire 106 to prevent evaporation or condensation of the electrolyte. The servo motor 4 synchronously controls the airflow to match the oxygen and electrolyte supply with the detection demand, and when the reference electrode 95 potential drifts, the oxygen flow is increased, and the compensation mechanism is replaced by physical structure instead of electronic control to reduce energy consumption.

[0070] Finally, after the system completes the detection and compensation, it enters the steady-state maintenance phase, and the signal feedback disc 7 continuously monitors the current stability of each modular detection unit 9. If the data fluctuation exceeds the threshold, a new round of cross-validation or maintenance prompt is triggered. The air guide mechanism 6 and the recovery mechanism 5 slow down and stop working until the whole process is completed. The low-maintenance cost is achieved through modular design, and the pain points of high false alarm rate and frequent maintenance of traditional sensors in a closed environment are solved. The system outputs real data of the concentration of environmental gas, providing a reliable basis for safety decision-making.
