Description

Technical Field

[0001] The present invention relates to the technical field of water quality detection, and in particular to a full-spectrum water quality online monitoring device and a monitoring method thereof. Background Art

[0002] Full-spectrum online water quality monitoring devices provide real-time monitoring of multiple water quality parameters (such as dissolved oxygen, turbidity, pH, and chemical oxygen demand), providing crucial support for water quality management, pollution warning, and environmental regulation. Their core function is to rapidly detect concentration changes of various substances in water using spectral technology. Data analysis promptly reflects water quality conditions, facilitating early identification of pollution sources, preventing the spread of contamination, and providing a data basis for water quality management. These devices primarily consist of a light source, a spectral detector, an optical sensor, a data processing unit, a display and alarm system, and a communication module. The light source provides broadband light to illuminate the water sample. The spectral detector captures the light signals reflected or transmitted by the sample to obtain spectral data. The optical sensor measures pollutant concentrations in real time. The data processing unit uses algorithms to process the spectral signals and convert them into water quality parameters. The display and alarm system provides real-time water quality information and issues alarms when anomalies are detected. The communication module supports remote data transmission, facilitating monitoring and management. The device illuminates the water body by emitting broadband light. Different water components absorb or scatter light of specific wavelengths. The spectral detector captures these changes and accurately calculates the concentration of various pollutants in the water by analyzing the spectral data and combining it with an established calibration model.

[0003] For example, a split full-spectrum water quality online monitoring device disclosed in application publication number CN111289452A consists of a monitoring host and a plurality of sensor probes. The sensor probes and the monitoring host are connected by photoelectric communication, wherein the sensor probes are used to immerse in a water sample environment to be tested to periodically and continuously monitor parameter changes of water quality factors and transmit the parameter changes in real time to the monitoring host for processing and transmission to a remote server. By arranging the light source unit at the top of the sensor probe body and the reflective unit at the bottom of the sensor probe, it is easy to adjust, control and replace the appropriate optical module, and the full-spectrum light source is placed outside the monitoring host. Deuterium lamps, for example, can be used as light sources, producing broadband spectra of ultraviolet, visible, and near-infrared light, and can control the light source capacity, enabling high-precision monitoring and analysis of multiple monitoring targets. However, these technologies require the deployment of multiple sensor probes within the same water area. To minimize the impact of variables during water quality testing and ensure consistency between sensor probes, personnel must carefully control the depth of each sensor probe within the water sample environment and its stability within the water. However, water environments often experience dynamic changes, such as water flow velocity, meteorological factors, and changes in dissolved gases, which can directly affect sensor stability. Although personnel can manually adjust the sensor depth, due to the high fluidity of the water, the sensor may still be pushed by the current or drift naturally over time, especially in areas with high water flow. Even if each sensor is manually adjusted to the appropriate depth and position initially, depth errors, offsets, or unstable positions between sensors may occur over time, affecting the consistency of water quality data and long-term monitoring effectiveness. Summary of the Invention

[0004] The object of the present invention is to provide a full-spectrum water quality online monitoring device and a monitoring method thereof. At least four long boards are arranged on the outside of a floating platform, and the built-in planetary gear drive unit in the floating platform is used to drive the main shaft and belt traction assembly on the long board to work. The belt traction assembly drives the slide and the full-spectrum water quality sensor to gradually move away from the floating platform. During the movement away, the horizontal sliding motion of the slide is converted into the downward motion of the support plate and the full-spectrum water quality sensor through the gear rack transmission assembly, so that the full-spectrum water quality sensor gradually penetrates into the water area to be detected, so that the depth of each sensor is consistent and the sensor located in the water body is ensured to be in a stable state, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: a full-spectrum water quality online monitoring device and a monitoring method thereof, comprising:

[0006] A floating platform, wherein at least four equally spaced long boards are mounted on the outer wall of the floating platform, and a float support structure is mounted on the end of the long board away from the floating platform, a slide is slidably mounted on the upper surface of the long board, and a screw depth adjustment structure is mounted on the top of the slide, a support plate is mounted on the movable end of the screw depth adjustment structure, and a full-spectrum water quality sensor for monitoring water quality is mounted at the center position of the bottom end of the support plate;

[0010] Preferably, the belt traction assembly includes a secondary shaft rotatably installed on one side of the top end of the long board and a synchronous wheel installed on one end of the secondary shaft and the main shaft surface. A belt unit for driving the slide to move horizontally is installed between two adjacent synchronous wheels on the same side. Tensioning wheels for tightening the belt unit are also rotatably installed on both sides of the top end of the long board.

[0011] Preferably, a guide rail is fixed on the upper surface of the long board, a cross plate frame is fixed on one side of the top of the slide, a dovetail sleeve that slides with the guide rail is fixed on one side of the bottom end of the cross plate frame, and one end of the belt unit is fixedly connected to the bottom end of the cross plate frame.

[0012] Preferably, the rack and pinion transmission assembly includes a helical rack fixed on the outer wall of one side of the long plate, a helical gear shaft rotatably installed on one side of the top end of the slide, and a belt transmission structure installed on the top end of the helical gear shaft for driving the screw depth adjustment structure to work, and the helical gear shaft is located below the cross plate frame.

The bottom end of the hollow threaded shaft passes through the nut pair and the outside of the slide and is rotatably connected to the top end of the support plate. The nut pair and the helical gear shaft maintain power connection through a belt transmission structure, and the cable connected to the top end of the full-spectrum water quality sensor passes through the hollow threaded shaft.

[0015] Preferably, the float support structure includes two T-arms fixed to one side of the bottom end of the long board, a pan head threadedly mounted on one side of the bottom end of the T-arm, and a float unit hingedly mounted on one side of the bottom end of the pan head, and the pan head is located below the secondary shaft.

[0016] The present invention also provides a full-spectrum water quality online monitoring method, such as the full-spectrum water quality online monitoring device described above, comprising the following steps:

[0017] S101: The staff installs the floating platform at an appropriate location in the target water area for water quality monitoring. The floating platform serves as the basic support structure of the entire device, enabling the device to float and remain stable on the water surface;

[0018] S102: The staff sends a working signal to the remote control module, and the remote control module controls the built-in planetary gear drive unit to work. The rotational power of the built-in planetary gear drive unit is synchronously transmitted to each main shaft, which is rotated by the main shaft, so that the main shaft drives the belt traction assembly to work;

[0019] S103: The belt traction assembly uses the traction force of the belt to achieve horizontal movement of the slide, the screw depth adjustment structure, the support plate, the full-spectrum water quality sensor and other components, so that the full-spectrum water quality sensor gradually moves away from the floating platform, ensuring that there is sufficient distance between multiple full-spectrum water quality sensors;

[0020] S104: When the slide is moving away from the floating platform, since power transmission is always maintained between the screw depth adjustment structure and the gear rack transmission assembly, the gear rack transmission assembly converts the translational motion of the slide into rotational motion and drives the screw depth adjustment structure to work. The screw depth adjustment structure drives the support plate and the full-spectrum water quality sensor to move slowly downward to adjust the water depth position of the full-spectrum water quality sensor until the full-spectrum water quality sensor can accurately reach the specified depth. The full-spectrum water quality sensor starts data collection every time it reaches the set depth. The staff can adjust the depth of the full-spectrum water quality sensor in real time as needed to obtain water quality data at different levels.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the full-spectrum water quality online monitoring device and its monitoring method can ensure that the moving distance of the full-spectrum water quality sensor in the water area is consistent through the design of at least four long plates on the outside of the floating platform, and the floating platform drives the main shaft and belt traction assembly on the long plate through the built-in planetary gear drive unit, and cooperates with the gear rack transmission assembly and the screw depth adjustment structure to make the support plate and the full-spectrum water quality sensor move in the vertical direction, ensuring that when the belt traction assembly drives the slide away from the floating platform, the depth of the full-spectrum water quality sensor gradually increases, that is, the horizontal sliding of the slide is converted into the downward movement of the full-spectrum water quality sensor through the gear rack transmission assembly, which helps to ensure that the downward movement of each full-spectrum water quality sensor in the water body is consistent, avoiding the depth inconsistency problem caused by manual operation errors or changes in the external environment, so that when the device performs water quality monitoring at multiple depth levels, all full-spectrum water quality sensors can sink to the specified depth simultaneously and synchronously and operate stably, greatly improving the comparability and reliability of water quality data;

[0022] Through the collaboration of the longboard, main shaft, belt traction assembly, and slide, the device can smoothly control the descent and long-distance travel of the full-spectrum water quality sensor. At the same time, the fine adjustment of the slide and screw depth adjustment structure further ensures that the sensor maintains a vertical and stable position in the water, preventing the sensor from tilting or shifting due to external factors such as water flow and waves, ensuring that the sensor always samples at the predetermined monitoring position, reducing errors and further increasing data reliability.

[0023] The full-spectrum water quality sensor can perform uniform and stable monitoring at different depths driven by the rack and pinion drive assembly and the lead screw depth adjustment structure, and can provide accurate real-time data based on different water quality parameters. It also ensures that all full-spectrum water quality sensors move downward synchronously, which can avoid the problem of incomplete or unrepresentative monitoring data caused by improper positioning of some sensors. Especially when it is necessary to monitor the water layer layer by layer, the water quality data at different depths can be directly compared and analyzed, thereby improving the overall monitoring accuracy of the device.

DETAILED DESCRIPTION

[0037] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] Embodiment 1, by Figures 1 to 6 The present invention includes a floating platform 1, on the outer wall of which at least four equally spaced long boards 3 are mounted, and a float support structure 4 is mounted on the end of the long board 3 away from the floating platform 1, a slide 8 is slidably mounted on the upper surface of the long board 3, and a screw depth adjustment structure 10 is mounted on the top of the slide 8, a support plate 11 is mounted on the movable end of the screw depth adjustment structure 10, and a full-spectrum water quality sensor 12 for monitoring water quality is mounted at the center position of the bottom end of the support plate 11;

[0039] Belt traction assembly 7, the belt traction assembly 7 is arranged on the upper surface of the long board 3, and a main shaft 5 for driving the belt traction assembly 7 is rotatably installed on one side of the top of the long board 3. A gear rack transmission assembly 9 is provided on the outer wall of the side of the long board 3 close to the slide 8, which maintains power connection with the screw depth adjustment structure 10. The gear rack transmission assembly 9 is used for the slide 8 to drive the screw depth adjustment structure 10 to drive the support plate 11 and the full-spectrum water quality sensor 12 to move downward when the slide 8 is horizontally away from the floating platform 1. The structural design of the floating platform 1 has sufficient buoyancy to support the entire device, while ensuring that the full-spectrum water quality sensor 12 can move downward stably in the water, and the float support structure 4 not only provides additional buoyancy support for the long board 3, but also ensures the balance of the floating platform 1 on the water surface, thereby making the movement trajectory of the full-spectrum water quality sensor 12 in the water more stable;

[0040] The floating platform 1 is provided with an internal planetary gear drive unit 6 for driving the main shaft 5 to rotate. A remote control module 13 is installed at the bottom of the floating platform 1. The output end of the remote control module 13 is electrically connected to the input end of the internal planetary gear drive unit 6.

[0041] The floating platform 1 is composed of an annular lip 101, a hollow hemispherical shell 102 and an upper shell cover 103. The upper shell cover 103 is integrally formed at the opening position of the top of the hollow hemispherical shell 102. The annular lip 101 is integrally formed on the outer wall of the hollow hemispherical shell 102. The long plate 3 is fixed to the top of the annular lip 101. The remote control module 13 is installed at the top of the hollow hemispherical shell 102. The top of the upper shell cover 103 is fixed with a tower 2 extending upward. The floating platform 1 is integrally formed by the hollow hemispherical shell 102 and the upper shell cover 103, so that the hollow hemispherical shell 102 and the upper shell cover 103 are integrally formed. A cavity is formed inside the cover 103 to accommodate air, and the annular lip 101 is fixedly connected to the long plate 3, ensuring that the various components such as the belt traction assembly 7, the screw depth adjustment structure 10, and the slide 8 are stably supported. The upper shell cover 103, the hollow hemispherical shell 102, and the float support structure 4 can float freely on the water surface, reducing the violent shaking caused by water flow or wind, thereby providing a stable foundation for the full-spectrum water quality sensor 12. Especially in waters with large fluctuations, the stability of the floating platform can ensure the continuity and accuracy of water quality monitoring.

[0042] The remote control module 13 allows the operator to monitor the operating status of the device through the control terminal or other locations on the shore, and can adjust the operating parameters of the device in real time, such as the sinking depth and sampling frequency of the full-spectrum water quality sensor 12. When the device is started, the remote control module 13 first receives the operating instructions from the operator and controls the floating platform 1, the built-in planetary gear drive unit 6, the full-spectrum water quality sensor 12 and other components to perform corresponding tasks;

[0043] The full-spectrum water quality sensor 12 and the water quality monitor host are connected via photoelectric communication. The full-spectrum water quality sensor 12 is used to immerse in a water sample environment to periodically and continuously monitor parameter changes of water quality factors and transmit the detected parameter changes in real time to the water quality monitor host. The water quality monitor host processes and transmits the data to the remote server where the staff is located.

[0044] The full-spectrum water quality sensor 12 can adopt the AMT / QGP-400 series online full-spectrum water quality sensor, which can quickly and synchronously measure the COD, DOC, TOC, BOD, nitrate nitrogen, color, turbidity, temperature and residual chlorine in the water by real-time and rapid measurement of the UV-visible / pure UV full-wavelength absorption spectrum of the water body, combined with the water quality model algorithm and calibration parameters, to achieve multi-parameter integration and online real-time water quality detection needs.

[0045] A full-spectrum online water quality monitoring method of this embodiment, such as the above-mentioned full-spectrum online water quality monitoring device, includes the following steps:

[0046] S101: The staff installs the floating platform 1 at an appropriate location in the target water area for water quality monitoring. The floating platform 1 serves as the basic support structure of the entire device, enabling the device to float and remain stable on the water surface;

[0047] S102: The staff sends a working signal to the remote control module 13, and the remote control module 13 controls the built-in planetary gear drive unit 6 to work. The rotational power of the built-in planetary gear drive unit 6 is synchronously transmitted to each main shaft 5, which is rotated by the main shaft 5, so that the main shaft 5 drives the belt traction assembly 7 to work;

[0048] S103: The belt traction assembly 7 uses the traction force of the belt to achieve horizontal movement of the slide 8, the screw depth adjustment structure 10, the support plate 11, the full-spectrum water quality sensor 12 and other components, so that the full-spectrum water quality sensor 12 gradually moves away from the floating platform 1, ensuring that there is a sufficient distance between the multiple full-spectrum water quality sensors 12;

[0049] S104: When the slide 8 is on the way away from the floating platform 1, since power transmission is always maintained between the screw depth adjustment structure 10 and the gear rack transmission assembly 9, the gear rack transmission assembly 9 converts the translational motion of the slide 8 into rotational motion and drives the screw depth adjustment structure 10 to work. The screw depth adjustment structure 10 drives the support plate 11 and the full-spectrum water quality sensor 12 to move slowly downward to adjust the water depth position of the full-spectrum water quality sensor 12 until the full-spectrum water quality sensor 12 can accurately reach the specified depth. The full-spectrum water quality sensor 12 starts data collection every time it reaches the set depth. The staff can adjust the depth of the full-spectrum water quality sensor 12 in real time as needed to obtain water quality data at different levels.

[0050] Example 2, based on Example 1, Figure 7 、 Figure 8 and Figure 9It is given that the built-in planetary gear drive unit 6 includes an annular sleeve 602 rotatably mounted on the upper surface of the annular lip 101, a servo motor 601 mounted on the outer wall of one side of the remote control module 13, and a transmission shaft 605 rotatably mounted on one side of the top of the annular lip 101. The outer wall and inner wall of the annular sleeve 602 are respectively fixed with an outer gear ring 603 and an inner gear ring 604. The top of the main shaft 5 is fixed with a driven gear disc 608 that meshes with the outer gear ring 603. The output end of the servo motor 601 is installed with a bevel gear transmission structure 607 for driving the transmission shaft 605 to rotate. The top of the transmission shaft 605 is fixed with a driven gear disc 608 that meshes with the inner gear ring 604. When the mutually meshing driving gears 606 use the built-in planetary gear drive unit 6 to drive the various main shafts 5 to rotate synchronously, the staff sends a working signal to the servo motor 601 through the remote control module 13, and the servo motor 601 first drives the transmission shaft 605 to rotate through the bevel gear transmission structure 607, so that the transmission shaft 605 drives the inner gear ring 604, the annular sleeve 602 and the outer gear ring 603 to rotate around the upper shell cover 103 and the hollow hemispherical shell 102 through the driving gear 606. Since the outer gear ring 603 meshes with the driven gear disc 608 at the top of the same main shaft 5, multiple main shafts 5 can be driven to rotate synchronously;

[0051] The built-in planetary gear drive unit 6 has a high torque output capacity and can provide sufficient power at a low speed to drive the main shaft 5, belt traction assembly 7, screw depth adjustment structure 10 and other components to work smoothly, suitable for stable operation under heavy load conditions;

[0052] The belt traction assembly 7, the rack and pinion transmission assembly 9, and the screw depth adjustment structure 10 share the built-in planetary gear drive unit 6 as the driving source, so that the full-spectrum water quality sensor 12 can move synchronously during translation and downward movement, effectively reducing the use of motors in the device, thereby reducing the construction cost and use cost of the device.

[0053] Example 3, based on Example 2, Figure 10 and Figure 11 It is given that the belt traction assembly 7 includes a secondary shaft 701 rotatably installed on one side of the top of the long board 3 and a synchronous wheel 702 installed on the secondary shaft 701 and one end of the surface of the main shaft 5. A belt unit 703 for driving the slide 8 to move horizontally is installed between the two adjacent synchronous wheels 702 on the same side. Tensioning wheels 704 for tightening the belt unit 703 are also rotatably installed on both sides of the top of the long board 3. After the main shaft 5 is driven, the main shaft 5 drives the secondary shaft 701 to rotate through the synchronous wheel 702 and the belt unit 703. Then the belt unit 703 drives the secondary shaft 701, the slide 8, the screw depth adjustment structure 10 and other components to move along the extension direction of the long board 3, so that the full-spectrum water quality sensor 12 approaches or moves away from the floating platform 1, so as to enable the detection area surrounded by each full-spectrum water quality sensor 12 to be adjusted;

[0054] A guide rail 301 is fixed to the upper surface of the long board 3, a cross plate frame 801 is fixed to one side of the top of the slide 8, and a dovetail sleeve 802 that slides with the guide rail 301 is fixed to one side of the bottom end of the cross plate frame 801. One end of the belt unit 703 is fixedly connected to the bottom end of the cross plate frame 801. During the movement of the slide 8, the dovetail sleeve 802 slides with the guide rail 301, so that the slide 8, the screw depth adjustment structure 10, the full-spectrum water quality sensor 12 and other components are more stable and reliable when moving;

[0055] The rack and pinion transmission assembly 9 includes a bevel rack 901 fixed to the outer wall of one side of the long plate 3, a bevel gear shaft 902 rotatably mounted on one side of the top of the slide 8, and a belt transmission structure 903 installed on the top of the bevel gear shaft 902 for driving the screw depth adjustment structure 10 to work. The bevel gear shaft 902 is located below the cross plate frame 801. The bevel gear shaft 902 includes a fixed shaft rotatably mounted on the top of the slide 8 and a bevel gear plate fixed at one end of the fixed shaft surface. The bevel gear plate and the bevel rack 901 are meshed with each other, and the top of the fixed shaft is rotatably connected to the bottom end of the dovetail sleeve 802.

[0056] During the horizontal movement of the carriage 8, the helical gear shaft 902 and the helical rack 901 are meshed with each other, so the helical gear shaft 902 is forced to rotate. At this time, the rotational motion of the helical gear shaft 902 is transmitted to the nut pair 1003 through the belt transmission structure 903;

[0057] The screw depth adjustment structure 10 includes a nut pair 1003 rotatably mounted at the center position of the top of the slide 8, a guide column 1001 slidably mounted at the corner position of the top of the slide 8, and a top plate 1002 fixed to the top of the four guide columns 1001. A hollow threaded shaft 1004 is installed inside the nut pair 1003. The top of the hollow threaded shaft 1004 is rotatably connected to the bottom end of the top plate 1002. The bottom end of the hollow threaded shaft 1004 passes through the nut pair 1003 and the outside of the slide 8 and is rotatably connected to the top of the support plate 11. The nut pair 1003 and the bevel gear shaft 902 are kept in motion by a belt transmission structure 903. The cable connected to the top of the full-spectrum water quality sensor 12 passes through the hollow threaded shaft 1004. When the nut pair 1003 rotates, the nut pair 1003 can drive the hollow threaded shaft 1004, the top plate 1002, the guide column 1001, and the support plate 11 to move downward. During this process, the downward movement depth of the support plate 11 and the guide column 1001 is proportional to the horizontal movement distance of the slide 8, until the full-spectrum water quality sensor 12 moves to the required water depth. The structural design of the screw rod can achieve very fine depth adjustment, which can be adjusted when the full-spectrum water quality sensor 12 moves downward to ensure that the sensor can accurately reach the target depth.

[0058] The cable connected to the top of the full-spectrum water quality sensor 12 passes through the outside of the hollow threaded shaft 1004 and is connected to the water quality monitor host. During this process, the cable leaves a margin for the full-spectrum water quality sensor 12 and the support plate 11 to move downward.

[0059] The guide column 1001, the top plate 1002, and the support plate 11 are designed to be stable, which can effectively prevent the interference of water flow and external factors on the position of the full-spectrum water quality sensor 12, and provide long-term stable depth control.

[0060] Example 4, based on Example 3, Figure 12 It is given that the float support structure 4 includes two T-arms 401 fixed to one side of the bottom end of the long board 3, a pan head 402 threadedly installed on one side of the bottom end of the T-arm 401, and a float unit 403 hingedly installed on one side of the bottom end of the pan head 402. The pan head 402 is located below the secondary shaft 701. The pan head 402 is installed on the bottom end of the T-arm 401 through a threaded head. Since the top of the float unit 403 and the pan head 402 maintain an active connection state, when the water surface fluctuates, the float unit 403 can float freely, thereby dynamically adjusting the buoyancy to ensure that the device can maintain balance at different water levels, thereby reducing violent shaking or displacement of the device and ensuring that the sensor can stably maintain a predetermined depth.

[0061] When the embodiment of the present application is in use, the staff first installs the floating platform 1 at an appropriate position in the target water area where water quality monitoring is to be carried out. The floating platform 1 serves as the basic support structure of the entire device, which can enable the device to float on the water surface and remain stable. Then the staff uses the cable and signal connector at the top of the full-spectrum water quality sensor 12 to connect to the external water quality monitor host. The water quality monitor host can be placed in the tower 2 or the floating platform 1, so that the water quality parameters collected by the full-spectrum water quality sensor 12 can be transmitted to the remote server where the staff is located through the water quality monitor host. Thereafter, the staff sends a working signal to the remote control module 13, and the remote control module 13 controls the built-in planetary gear drive unit 6 to work. The rotational power of the built-in planetary gear drive unit 6 is synchronously transmitted to each main shaft 5, and the main shaft 5 is used to rotate, so that the main shaft 5 drives the belt traction assembly 7 to work. The belt traction assembly 7 uses the traction force of the belt to realize the horizontal movement of the slide 8, the screw depth adjustment structure 10, the support plate 11, the full-spectrum water quality sensor 12 and other components, so that the full-spectrum water quality sensor 1 2 gradually moves away from the floating platform 1, ensuring that there is enough distance between the multiple full-spectrum water quality sensors 12, ensuring that the water quality detection range can be effectively expanded. When the slide 8 is away from the floating platform 1, since the power transmission is always maintained between the screw rod depth adjustment structure 10 and the gear rack transmission assembly 9, the gear rack transmission assembly 9 converts the translational motion of the slide 8 into a rotational motion and drives the screw rod depth adjustment structure 10 to work. The screw rod depth adjustment structure 10 drives the support plate 11 and the full-spectrum water quality sensor 12 to slowly move downward to adjust the water depth position of the full-spectrum water quality sensor 12. The position is adjusted until the full-spectrum water quality sensor 12 can accurately reach the specified depth. After the slide 8 moves to the vicinity of the position of the float support structure 4, the downward depth of the full-spectrum water quality sensor 12 also reaches the limit position. The full-spectrum water quality sensor 12 starts data collection every time it reaches the set depth, and uploads the data to the water quality monitor host and the operator end. During this process, the staff can adjust the depth of the full-spectrum water quality sensor 12 in real time according to monitoring needs to obtain water quality data at different levels, providing reliable data support for comprehensive analysis of water quality changes.
