Description

Technical Field

[0001] This invention relates to the field of fungicide detection technology, specifically to a fungicide detection device. Background Technology

[0002] In the field of environmental monitoring, the detection of fungicide residues in water, soil, and other media is a crucial step in assessing ecological risks and ensuring environmental safety. Existing fungicide detection technologies have developed various mature detection devices and methods to meet the analytical needs of different scenarios. In laboratory environments, gas chromatography, high-performance liquid chromatography, and their coupling systems with mass spectrometry are currently the mainstream precision analytical equipment. These instruments can efficiently separate, qualitatively identify, and accurately quantify multiple fungicides in samples, offering high detection sensitivity and accurate, reliable results, making them the "gold standard" for environmental monitoring. Meanwhile, ultraviolet-visible spectrophotometers and atomic absorption spectrometers... Equipment such as these are also used for the detection and analysis of specific types of bactericides or their characteristic elements. To meet the needs of rapid on-site screening and emergency monitoring, portable detection devices are also widely used. For example, colloidal gold test strips based on the principle of immunochromatography and enzyme-linked immunosorbent assay kits can achieve rapid qualitative or semi-quantitative analysis of specific types of bactericides. They are easy to operate and have a fast response. In addition, various portable electrochemical sensors and water toxicity analyzers based on the principle of bioluminescence can conduct on-site assessments of the pollution status or comprehensive toxicity of samples through direct or indirect biochemical reactions, providing an effective tool for rapidly assessing environmental risks.

[0003] Existing technologies still have some limitations. While existing fungicide detection technologies have formed a system, their inherent limitations become increasingly apparent when facing complex and dynamic environmental pollution monitoring needs. Traditional monitoring methods mainly rely on manual on-site sampling, followed by transporting the samples to a fixed laboratory for analysis using large-scale chromatographic or mass spectrometric instruments. This method is constrained by personnel accessibility and safety in the sampling process, and sampling points are usually limited to easily accessible locations. It is difficult to obtain representative samples from key locations such as the center of the water body and the nearshore of pollution sources, and it is even more difficult to conveniently achieve stratified sampling of water profiles or soil depths. This results in insufficient representativeness of monitoring data in the spatial dimension, making it difficult to truly depict the three-dimensional distribution of pollutants. In the temporal dimension, manual periodic sampling and laboratory analysis are also problematic. The long cycle of sampling and report acquisition typically takes several days or even weeks, making it impossible to capture short-term pollution events such as instantaneous emissions and intermittent leaks. This results in a significant lag in monitoring timeliness and a weak environmental early warning capability. Furthermore, most existing mainstream detection devices focus on the precise quantification of the chemical concentration of specific bactericides in the target list, and their assessment paradigm is based on the compliance standards of a single substance. However, pollutants in the environment often exist in the form of complex mixtures, and the components may produce synergistic, additive, or antagonistic "cocktail effects." It is difficult to accurately assess the actual ecological risk by simply adding the concentrations of a limited number of chemical substances. Current technologies lack effective means to simultaneously and rapidly assess the comprehensive biotoxicity of samples at the testing site, posing a significant hidden danger of underestimating the risk of mixed exposure. Summary of the Invention

[0004] The purpose of this invention is to provide a bactericide detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bactericide detection device, comprising: The mounting base has a support frame on its upper surface, and a testing mechanism is provided on the upper surface of the support frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In this solution, by incorporating a housing assembly, a small chromatograph and a bacterial detection tube are integrated into the same detection box. The data output from both is simultaneously acquired and fused by a data processor. This allows a single detection process to simultaneously obtain two key indicators: the precise chemical concentration of the target bactericide and the comprehensive biotoxicity of the sample. This overcomes the limitation of traditional detection equipment that can only provide single chemical analysis data. By comparing the expected relationship between the concentration of a specific bactericide and the measured biotoxicity, the data processor can automatically identify anomalies where the chemical analysis concentration is low but the biotoxicity is high. This provides early warning of the possible presence of unknown toxic pollutants or synergistic enhancement effects between known pollutants. This solves the industry problem that existing environmental monitoring standard methods seriously underestimate the ecological risks of actual mixed exposure. In addition, the integrated automatic cleaning system and waste liquid collection unit ensure that the system can operate continuously for a long time, at a high frequency, and without cross-contamination under unattended conditions. This successfully deploys the precise and multi-dimensional analysis capabilities that were originally only possible in the laboratory to complex outdoor environments. 2. In this solution, by incorporating sampling components and employing a modular and automated UAV-mounted design, the three-dimensional spatial maneuverability of the UAV is transformed into high-resolution, multi-media environmental sample collection capabilities. The UAV's bottom features a sliding base plate for liquid and solid samples, allowing a single UAV to automatically collect liquid samples from different geographical locations and water depths, as well as soil / sediment columnar samples, within a single mission. These samples are then independently stored in multiple liquid and solid storage chambers. This overcomes the strict limitations of traditional manual sampling due to terrain, accessibility, safety, and efficiency, enabling a three-dimensional, grid-like survey of contaminated sites. It also allows easy access to key locations difficult for personnel to reach, such as the center of water bodies, steep banks, and swamps, improving the spatial representativeness and timeliness of sampling. This provides the possibility of capturing instantaneous or intermittent pollution events, achieving a seamless closed loop between sampling and detection. It avoids sample deterioration and contamination during transportation and storage, ensuring the consistency and high fidelity of subsequent analytical data. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1: Please refer to Figures 1 to 8 A bactericide detection device, comprising: Mounting base 1 serves as the foundation for the entire device, secured to a concrete base with anchor bolts to ensure long-term stability and wind and earthquake resistance in complex outdoor environments. A support frame 2 is mounted on the upper surface of mounting base 1, and a testing mechanism is mounted on the upper surface of support frame 2. The testing mechanism includes a housing assembly and a sampling assembly. The housing assembly comprises a shell component and a test component. The shell component includes a detection box 3, a box-like structure typically made of waterproof and corrosion-resistant stainless steel to protect the delicate analytical components. The detection box 3 is located on the upper surface of support frame 2, and the test component is located inside the shell component. A bearing base plate 7 is mounted on the upper surface of the detection box 3, with a central opening at its center. Hole 9 serves as the sole entry point for all samples to be tested. The upper surface of the supporting base plate 7 is equipped with a limiting frame 8, forming a guiding and limiting funnel. This funnel interacts with the protruding structure of the landing gear or fuselage of the sampling drone 6 when it returns to its original position, automatically correcting its hovering position and ultimately ensuring that the sample discharge port of the sampling drone 6 is precisely aligned with the central opening 9. The upper surface of the supporting base plate 7 is equipped with a rotatable storage top cover 5. A control electric shaft is provided at the connection between the storage top cover 5 and the supporting base plate 7. A data processor 10 is also provided on the inner side surface of the detection box 3. Multiple discharge ramps 19 are provided on the bottom surface of the detection box 3. A storage box 20 is provided on one side surface of the discharge ramp 19. An automatically opening and closing electric flip cover is provided on the upper surface of the storage box 20. The mounting base 1 provides a stable base for the entire system. The detection box 3, fixed above it by the support frame 2, constitutes the core analysis unit of the device. The sampling components are mainly attached to the surface of the sampling drone 6, which moves and collects data remotely. Normally, the sampling drone 6 is stored inside the storage cover 5. When the preset collection time is reached or when remote signal from the operator initiates collection, the data processor 10 drives the control motor shaft at the connection between the storage cover 5 and the support base plate 7 to rotate, causing the storage cover 5 to flip and expose the top of the support base plate 7. At this time, the sampling drone 6 can fly away from the restraining frame 8 to perform remote sampling. After the collection is completed, the sampling drone 6 flies back to the top of the support base plate 7, and the restraining frame above the support base plate 7... 8 can contact the support feet on the bottom of the sampling drone 6 to adjust the position of the sampling drone 6. After the sampling drone 6 stops above the support base plate 7, its bottom surface is exactly at the center of the central opening 9. During the test, the rotating hook block 29 on the side surface of the bottom bracket 23 rotates to cancel the hooking effect with the central support frame 27. Then, the data processor 10 drives the electric shaft 28 to rotate, so that the central support frame 27 rotates downward by ninety degrees, so that one end of the liquid storage tank 32 or solid storage tank 42 is aligned with the top of the receiving vertical tube 12. Then, the rotating bottom cover 43 at the bottom of the liquid storage tank 32 or solid storage tank 42 rotates to discharge the internal sample and enter the interior of the receiving vertical tube 12. The four receiving vertical tubes 12 can simultaneously detect samples collected from four different locations.

[0018] The test component is the analytical core integrated inside the detection housing 3. The test component includes a miniature chromatograph 16, which is located on the bottom surface inside the detection housing 3. This miniature chromatograph 16 can be a miniaturized gas chromatograph with rapid separation and high-sensitivity detection capabilities. Four chromatographic detection tubes 17 and four bacterial detection tubes 18 are located on the side surface of the miniature chromatograph 16. Each bacterial detection tube 18 constitutes an independent microbial electrochemical sensor unit, containing an active microbial membrane sensitive to pollutants and a microelectrode connected to the membrane. A chromatographic detection tube 17 and a bacterial detection tube 18 form a group. Each group of chromatographic detection tubes 17 and bacterial detection tubes 18... Each detection tube 18 has a branch pipe 15 on its upper surface. The branch pipe 15 is a microfluidic Y-shaped flow path device with a common inlet at the top and two outlets that are precisely guided to the corresponding chromatographic detection tube 17 and bacterial detection tube 18, respectively. The upper surface of the branch pipe 15 is provided with a connecting vertical pipe 12. The upper openings of the four connecting vertical pipes 12 are located at the center of the central opening 9. The inner side surface of the detection box 3 is provided with a cleaning liquid box 11. The bottom surface of the cleaning liquid box 11 is provided with four cleaning branch pipes 14. One end of the cleaning branch pipe 14 is provided with a small water pump 13. One side surface of the small water pump 13 is connected to one side surface of the connecting vertical pipe 12. One side surface of the detection box 3 is provided with an injection hole 4, which is connected to the interior of the cleaning liquid box 11. After the sample falls through the central opening 9 in the center of the support base plate 7 into the receiving vertical pipe 12 directly below it, it is then precisely distributed by the branch pipe 15 to four independent parallel detection channels. In each channel, the sample simultaneously flows into the chromatographic detection tube 17 and the bacterial detection tube 18. The chromatographic detection tube 17 is connected to the miniature chromatograph 16 to perform highly selective separation and precise quantification of multiple target bactericides. At the same time, the immobilized active microbial biosensors in the adjacent bacterial detection tube 18 monitor the degree of inhibition of their metabolic activities, such as current or luminescence intensity, to determine the comprehensive biotoxicity of the sample in real time and in situ, directly addressing the question of the actual extent of harm. The data processor 10 simultaneously collects and fuses the data from both, fundamentally overcoming the limitations of existing standardization methods. The quasi-method has a major flaw: it only assesses the compliance of a single substance and seriously underestimates the ecological risks of mixed exposure. After the test is completed, in order to prevent cross-contamination and ensure the long-term stability of the equipment, the cleaning solution stored in the cleaning liquid box 11 is automatically flushed by the small water pump 13 through the cleaning branch pipe 14 into the chromatographic detection tube 17, the bacterial detection tube 18 and the upstream flow path. The waste liquid is discharged through the discharge ramp 19, or it can be opened by the electric flip cover driven by the remote signal. The discharged sample is stored in the sealed storage box 20 so that the staff can take the sample away for further testing. This ensures that the equipment can perform high-frequency tests without manual maintenance when unattended, and solves the maintenance problem faced by traditional precision instruments when deployed outdoors for a long time.

[0019] The sampling component is an active unit for collecting samples from a multi-dimensional spatial environment. Its core carrier is a sampling drone 6 with autonomous navigation and precise hovering capabilities. A high-resolution observation camera 21 is integrated on the upper surface of the sampling drone 6. A meshing motor is mounted on one side of the sampling drone 6, and a top movable plate 22 is mounted on the output shaft of the meshing motor. A bottom support 23 is mounted on the bottom surface of the sampling drone 6, with a central limiting plate 24 on the bottom surface of the bottom support 23 and a central support frame 27 on the bottom surface of the bottom support 23. An electric shaft 28 is located at the connection between the bottom support 23 and the central support frame 27. A rotating hook block 29 is mounted at one end of the bottom support 23. A rotating shaft is provided at the connection between the 9 and the bottom support 23. Two limiting crossbars 33 are provided at both ends of the central support frame 27. An electric push rod 34 is provided between the two limiting crossbars 33. The sampling assembly also includes a liquid storage component and a storage component. The liquid storage component is specifically responsible for the automated collection and storage of liquid samples (such as surface water, groundwater, and wastewater). The liquid storage component includes: a liquid sample sliding base plate 25, which is connected to the end of the output shaft of one of the electric push rods 34. A rotating support frame 30 is provided on the upper surface of the liquid sample sliding base plate 25. A rotatable rolling frame 31 is provided on the upper surface of the rotating support frame 30. Multiple... A liquid storage chamber 32 has a rotating bottom cover 43 at one end and a movable sealing block 60 at the other end. A connecting spring 61 is provided at the connection between the movable sealing block 60 and the liquid storage chamber 32. An injection opening 41 is provided on the upper surface of the liquid storage chamber 32. A small support frame 44 is also provided on the upper surface of the liquid sample sliding base plate 25. A bottom motor 45 is provided on the bottom surface of the small support frame 44. A drive gear 46 is provided at the end of the output shaft of the bottom motor 45. A driven gear 47 meshes with the upper surface of the drive gear 46. A connecting rod is provided on one side surface of the driven gear 47. One end of the connecting rod is connected to one end of the rolling frame 31. The small support frame 44... The upper surface of 4 is provided with a top slide 48, the upper surface of the top slide 48 is provided with a sliding injection pipe 49, the upper surface of the top slide 48 is provided with a plurality of small telescopic rods 50, the output shaft end of the small telescopic rods 50 is connected to one side surface of the sliding injection pipe 49, one side surface of the top slide 48 is provided with an electric rotating disk 51, one side surface of the electric rotating disk 51 is provided with a sliding rod frame 35, one end of the sliding rod frame 35 is provided with a drive motor 38, the output shaft of the drive motor 38 is provided with a meshing block, one side surface of the meshing block is provided with a water pumping pipe 62, one end of the water pumping pipe 62 is provided with a water pumping head 36, and one end of the water pumping pipe 62 is connected to the sliding injection pipe 49 with a water delivery pipe 37. The sampling drone 6 serves as the system's aerial mobile platform. Its bottom is precisely controlled by an electric push rod 34 to slide the liquid sample sliding base plate 25. When water profile sampling is required, the electric push rod 34 pushes the liquid sample sliding base plate 25 upwards toward the central limiting plate 24 on the central support frame 27 until one of its side differential blocks 40 contacts the central limiting plate 24 on the bottom surface of the bottom bracket 23. This moves the liquid sample sliding base plate 25 to the center position on the bottom surface of the sampling drone 6, which is the working position. Subsequently, sampling... The UAV 6 flies to the preset coordinate point and hovers. The electric rotating disk 51 drives the sliding rod 35 to rotate 90 degrees, pointing the pump head 36 towards the water surface below. Then, the drive motor 38 starts. Through the meshing effect of the output shaft of the drive motor 38 and the meshing block, the entire sampling mechanism is driven to descend, so that the pump head 36 is immersed to the target depth. The water pump in the pumping pipe 62 works to pump the water sample into the sliding injection pipe 49 through the water delivery pipe 37. At the same time, in order to complete the collection of multiple sample sequences, the bottom motor 45 meshes with the driven gear 47 through the drive gear 46. The mechanism drives the rotating frame 31 to rotate, precisely aligning the injection opening 41 of the specific empty liquid storage chamber 32 with the lower part of the sliding injection tube 49. The sliding injection tube 49 is inserted into one end of the liquid storage chamber 32 under the push of the small telescopic rod 50, and the movable sealing block 60 is pushed inward, so that the surface of the injection opening 41 on the bottom of the sliding injection tube 49 is in contact with the sample and injected. After the injection is completed, the sliding injection tube 49 is withdrawn from the inside of the liquid storage chamber 32 under the contraction of the small telescopic rod 50. The movable sealing block 60 automatically seals the chamber opening under the action of the connecting spring 61. Rotating the bottom cover 43 can further ensure that there is no leakage during transportation. This mechanism allows a single UAV to collect multiple water samples at different points and depths in a single mission through program control, and achieve physical isolation and storage between samples. It transforms the three-dimensional spatial maneuverability of the UAV into a high-resolution three-dimensional profile sampling capability for water pollutants, completely breaking through the limitation that manual or fixed samplers can only obtain surface samples at a few easily accessible points. It provides a revolutionary data acquisition method for truly and comprehensively reflecting the spatial distribution and migration patterns of pollutants in water.

[0020] The storage component is the core module of the sampling drone 6 used to collect and store solid environmental samples (such as soil, sediment, plant tissue, etc.). The storage component includes: a solid sample sliding base plate 26, which is connected to the end of the output shaft of an electric push rod 34. Side differential blocks 40 are provided on one side surface of both the solid sample sliding base plate 26 and the liquid sample sliding base plate 25. A rotating support frame 30 is also provided on the upper surface of the solid sample sliding base plate 26. A rolling cylinder 39 is provided on the upper surface of the rotating support frame 30. Four solid storage chambers 42 are provided on the surface of the rolling cylinder 39. A flip-top cover 52 is provided at one end of each solid storage chamber 42. The upper surface of the solid sample sliding base plate 26... The surface is also equipped with a small support frame 44 and a bottom motor 45 with the same structure as the liquid sample sliding base plate 25. The small support frame 44 has side telescopic rods 54 on both sides. The output shaft of the side telescopic rods 54 has a feeding pipe 53 at the end. The solid sample sliding base plate 26 has a drive turntable 55 on one side. The drive turntable 55 has a rotating vertical rod 56 on the upper surface. The rotating vertical rod 56 has a control motor 58 on the upper surface. The connection between the control motor 58 and the rotating vertical rod 56 has a miniature turntable 57. The output shaft of the control motor 58 has a material picking drum 59 at the end. The material picking drum 59 is a hollow cylindrical drilling tool with a cutting edge at the bottom opening. The solid sample collection module, installed alongside the liquid storage component on the bottom support 23, consists of a solid sample sliding base plate 26 and a rolling cylinder 39. During sampling, the solid sample sliding base plate 26 is pushed by an electric push rod 34 to move upwards towards the central limiting plate 24 on the central support frame 27 until the side differential block 40 on one side contacts the central limiting plate 24 on the bottom surface of the bottom support 23, moving the solid sample sliding base plate 26 to the center position of the bottom surface of the sampling drone 6. The sampling drone 6 is positioned at the soil or sediment sampling point, and the drive turntable 55 drives the sampling drum 59 to rotate 90 degrees, so that the bottom opening of the sampling drum 59 contacts the ground surface. The control motor 58 drives the sampling drum 59 to rotate and cut in, collecting a columnar soil sample. Subsequently, the micro turntable 57 adjusts the angle of the sampling drum 59, and simultaneously... The bottom motor 45 drives the rotating drum 39 to rotate, transferring an empty solid storage chamber 42 to the bottom of the discharge pipe 53. The side telescopic rod 54 pushes the discharge pipe 53 to connect with the solid storage chamber 42. The soil sample in the sampling drum 59 is introduced into the discharge pipe 53 and finally enters the solid storage chamber 42. The flip cover 52 then automatically closes to complete the seal. This process realizes standardized, undisturbed collection and sealed storage of solid media. Through modular design, a single UAV can simultaneously and automatically collect paired samples of two different environmental media, water and solid, in a single flight mission. This solves the problem of water and soil sampling separation and the difficulty in accurately matching data in time and space in traditional monitoring. It provides a sample basis for studying the migration, transformation, adsorption and desorption behavior of bactericides in the "water-soil-sediment" system and cross-media comprehensive risk assessment.

[0021] The working principle of this invention is: This solution consists of a fixed detection base station and a mobile sampling drone 6, which together constitute a complete automated monitoring system. The fixed base station includes a mounting base 1, a support frame 2, and a detection box 3 as the core analysis unit. In standby mode, the sampling drone 6 is stored inside the storage cover 5 above the detection box 3. After starting work, the storage cover 5 is opened under the control of the electric shaft, and the drone 6 takes off from the restraint frame 8 to perform the preset sampling task. According to instructions, the sampling drone 6 can autonomously select and switch between liquid or solid sampling modules mounted on its bottom. When sampling water, the electric push rod 34 pushes the liquid sample sliding base plate 25 to the working position. The drone 6 flies to the target water area and adjusts the angle of the sliding rod frame 35 via the electric rotating disk 51, so that the water pump head 36 is vertically downward. The drive motor 38 drives the sampling mechanism to descend, immersing the water pump head 36 to a predetermined depth. The water pump in the water pumping pipe 62 is activated, and the extracted water sample is transported to the sliding injection pipe 49 via the water delivery pipe 37. At the same time... The bottom motor 45 drives the rolling frame 31 to rotate through the meshing of the drive gear 46 and the driven gear 47, aligning the injection opening 41 of an empty liquid storage tank 32 with the sliding injection tube 49. The sliding injection tube 49 is pushed into the opening by the small telescopic rod 50, opening the movable sealing block 60 and injecting the sample. After the injection is completed, the injection tube is withdrawn, and the movable sealing block 60 is reset and sealed under the action of the connecting spring 61. This process can be repeated, and water samples at different points and depths can be stored in different liquid storage tanks 32 in sequence to achieve physical isolation storage of multiple samples. When soil or sediment sampling is required, the UAV 6 uses another set of electric push rods 34 to push the solid sample sliding base plate 26 to the working position. After arriving at the sampling point, the drive turntable 55 drives the material collection drum 59 to rotate to a vertically downward working posture. The control motor 58 drives the material collection drum 59 to rotate, cutting into the soil to collect columnar samples. After sampling, the bottom motor 45 drives the rolling cylinder 39 to rotate, transferring an empty solid storage chamber 42 to the bottom of the discharge pipe 53. The side telescopic rod 54 pushes the discharge pipe 53 to connect with the storage chamber. The micro turntable 57 adjusts the angle of the material collection drum 59, pours the soil sample into the discharge pipe 53 and finally falls into the solid storage chamber 42. The flip cover 52 automatically closes and seals. After completing multi-point, multi-media sampling, the UAV 6 automatically returns and lands precisely on the support base plate 7. Its position is corrected by the limiting frame 8 so that the center of the body is aligned with the center opening 9. Then, the hook block 29 is rotated to unlock, and the electric shaft 28 drives the center support frame 27 to rotate downward 90 degrees so that the discharge port of the fully loaded liquid storage tank 32 or solid storage tank 42 is aligned with the receiving vertical pipe 12 below. The bottom cover 43 is rotated to open, and the sample falls into the corresponding receiving vertical pipe 12 through the center opening 9 under the action of gravity. The four receiving vertical pipes 12 can simultaneously introduce four samples from different sources. After the sample enters the detection flow path, it is simultaneously and equally distributed to the parallel chromatographic detection tube 17 and bacterial detection tube 18 via the split branch tube 15. The chromatographic detection tube 17 is connected to the miniature chromatograph 16 to separate and accurately quantify the specific bactericide in the sample. At the same time, the active microbial sensor fixed in the bacterial detection tube 18 measures the overall biotoxicity of the sample in situ by monitoring the degree of inhibition of microbial metabolic activity (such as current) in real time. The data processor 10 simultaneously collects chemical concentration data from the miniature chromatograph 16 and biological effect data from the bacterial detection tube 18 and performs fusion analysis. By comparing the chemical analysis results with the biotoxicity intensity, it can identify whether there is a synergistic enhancement effect between unknown toxic substances or pollutants, thereby overcoming the shortcomings of traditional methods that only assess whether a single substance exceeds the standard and seriously underestimate the actual risk of mixed exposure. After a single test analysis is completed, in order to prepare for the next test and ensure long-term operational stability, the system initiates a self-cleaning program to clean the special cleaning solution stored in the liquid tank 11. Driven by a small water pump 13, the solution is pumped into the receiving riser 12, the diversion branch 15, the chromatographic detection tube 17, and the bacterial detection tube 18 through the cleaning branch pipe 14, performing a reverse flush on all pipelines through which the samples flow. The waste liquid generated is guided through the discharge ramp 19 and finally discharged into the sealable storage box 20 for temporary storage. Alternatively, the electric flip cover can be opened remotely for periodic cleaning by maintenance personnel. This fully automatic online cleaning and waste liquid collection function ensures that the system can perform high-frequency, continuous testing tasks under unattended outdoor conditions without the need for manual cleaning and maintenance, greatly improving the long-term deployment capability of the equipment in the field. The entire system operates in a cycle, realizing full-process automation from intelligent sampling, in-situ analysis, mixed toxicity assessment to automatic maintenance.
