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] The full-spectrum water quality online monitoring device provides important support for water quality management, pollution warning, environmental supervision, etc. by real-time monitoring of multiple water quality parameters in the water body (such as dissolved oxygen, turbidity, pH value, chemical oxygen demand, etc.). Its core function is to use spectral technology to quickly detect the concentration changes of various substances in the water body, and timely reflect the water quality status through data analysis, which helps to identify the pollution source early, avoid the spread of water pollution, and provide data basis for water quality management. The structure of this type of device is mainly composed of light source, spectral detector, optical sensor, data processing unit, display alarm system and communication module. The light source provides wide-band light to illuminate the water sample, the spectral detector obtains spectral data by capturing the light signal reflected or transmitted by the water sample, and the optical sensor measures the concentration of pollutants in real time. The data processing unit processes the spectral signal through an algorithm and converts it into water quality parameters, and the display and alarm system displays the water quality information in real time and issues an alarm when an abnormality is detected. The communication module supports remote data transmission, which is convenient for monitoring and management. The device emits wide-band light to illuminate the water. 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 the established calibration model. For example, a split full-spectrum water quality online monitoring device disclosed in application publication number CN111289452A is composed 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 quality sample environment 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. The light source unit is arranged at the top of the sensor probe body and the reflection unit is arranged at the bottom of the sensor probe, which can facilitate adjustment, control and replacement of appropriate optical modules, and the full-spectrum light source is placed outside the monitoring host. For example, deuterium lamp light sources can be used to generate ultraviolet, visible and near-infrared broadband spectra, and light source capacity can be controlled to achieve high-precision monitoring and analysis of multiple monitoring objects. However, the above technology requires the deployment of multiple sensor probes in the same water area during use, and in order to reduce the influence of variables in the water quality detection process and the consistency between each sensor probe, the staff needs to control the depth of each sensor probe in the water quality sample environment and the stability in the water. However, the water environment often has dynamic changes, such as water flow velocity, meteorological factors, changes in dissolved gases, etc. These factors will directly affect the stability of the sensor. Although the staff can manually adjust the depth of the sensor, due to the strong fluidity in the water body, the sensor may still be pushed by the water flow or drift naturally for a long time, especially in areas with large water flow. Even if each sensor is manually adjusted to the appropriate depth and position at the beginning, over time, there will still be water depth errors, offsets or unstable positions between each sensor, which will affect the consistency of water quality data and long-term monitoring effects. Summary of the invention

[0003] The object of the present invention is to provide a full-spectrum water quality online monitoring device and a monitoring method thereof.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Embodiment 1, by Figures 1 to 6 The present invention comprises a floating platform 1, at least four long boards 3 with equal spacing are installed on the outer wall of the floating platform 1, and a floating ball support structure 4 is installed at one end of the long board 3 away from the floating platform 1, a slide 8 is slidably installed on the upper surface of the long board 3, and a screw depth adjustment structure 10 is installed at the top of the slide 8, a support plate 11 is installed at the movable end of the screw depth adjustment structure 10, and a full-spectrum water quality sensor 12 for monitoring water quality is installed at the center position of the bottom end of the support plate 11; Belt traction assembly 7, belt traction assembly 7 is arranged on the upper surface of long board 3, one side of the top of long board 3 is rotatably installed with main shaft 5 for driving belt traction assembly 7 to work, and the outer wall of one side of long board 3 close to slide 8 is provided with gear rack transmission assembly 9 which maintains power connection with screw rod depth adjustment structure 10, gear rack transmission assembly 9 is used for slide 8 on the way of horizontally moving away from floating platform 1, drives screw rod depth adjustment structure 10 to drive support plate 11 and full-spectrum water quality sensor 12 to move downward, the structural design of floating platform 1 has sufficient buoyancy to support the whole device, and ensures that full-spectrum water quality sensor 12 can move downward stably in water, and float support structure 4 not only provides additional buoyancy support for long board 3, but also ensures the balance of floating platform 1 on water surface, so that the movement trajectory of full-spectrum water quality sensor 12 in water is more stable; The floating platform 1 is provided with a built-in 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 built-in planetary gear drive unit 6. 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 board 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 board 3 to ensure that the belt traction assembly 7, the screw depth adjustment structure 10, the slide 8 and other components are stably supported. The upper shell cover 103, the hollow hemispherical shell 102, and the floating ball 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; The remote control module 13 allows the operator to monitor the working status of the device through the control terminal or other locations on the shore, and can adjust the working 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 operation instructions from the staff, and controls the floating platform 1, the built-in planetary gear drive unit 6 and the full-spectrum water quality sensor 12 and other parts to perform corresponding tasks; The full-spectrum water quality sensor 12 and the water quality monitor host are connected by photoelectric communication, wherein the full-spectrum water quality sensor 12 is used to immerse in a water quality sample environment to periodically and continuously monitor the parameter changes of water quality factors and transmit the detected parameter changes to the water quality monitor host in real time, and the water quality monitor host processes and transmits them to the remote server where the staff is located; 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, chromaticity, turbidity, temperature, residual chlorine and other parameters 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 realize multi-parameter integration and online real-time water quality detection needs.

[0019] A full-spectrum water quality online monitoring method of this embodiment, such as the full-spectrum water quality online monitoring device described above, comprises the following steps: S101: The staff installs the floating platform 1 at an appropriate position in the target water area to be monitored for water quality. The floating platform 1 serves as the basic supporting structure of the entire device, which enables the device to float on the water surface and remain stable; 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, and the rotary 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; S103: 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 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; S104: When the slide 8 is on the way 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 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 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.

[0020] Embodiment 2, based on embodiment 1, Figure 7 , Figure 8 and Fig. 9 It 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, an outer gear ring 603 and an inner gear ring 604 are respectively fixed on the outer wall and the inner wall of the annular sleeve 602, a driven gear disc 608 meshing with the outer gear ring 603 is fixed on the top of the main shaft 5, a bevel gear transmission structure 607 for driving the transmission shaft 605 to rotate is installed at the output end of the servo motor 601, and a bevel gear transmission structure 607 for driving the transmission shaft 605 to rotate is fixed on the top of the transmission shaft 605 When the mutually meshing driving gears 606 use the built-in planetary gear drive unit 6 to drive each main shaft 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 is meshed 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; The built-in planetary gear drive unit 6 has a high torque output capacity and can provide sufficient power at a relatively low speed to drive the main shaft 5, the belt traction assembly 7, the screw depth adjustment structure 10 and other components to work smoothly, and is suitable for stable operation under heavy load conditions; The belt traction assembly 7, the gear rack transmission assembly 9, and the screw depth adjustment structure 10 share the built-in planetary gear drive unit 6 as a 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.

[0021] Embodiment 3, based on embodiment 2, Fig.10 and Fig.11 It is given that the belt traction assembly 7 includes a secondary shaft 701 rotatably installed on one side of the top end of the long board 3 and a synchronous wheel 702 installed on the secondary shaft 701 and one end of the main shaft 5 surface. A belt unit 703 for driving the slide 8 to move horizontally is installed between 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 end 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 is close to or 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; 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, a dovetail sleeve 802 that slides with the guide rail 301 is fixed to one side of the bottom of the cross plate frame 801, one end of the belt monomer 703 is fixedly connected to the bottom end of the cross plate frame 801, and during the movement of the slide 8, the dovetail sleeve 802 slides with the guide rail 301, so that the slide 8, the screw rod depth adjustment structure 10, the full-spectrum water quality sensor 12 and other components are more stable and reliable when moving; The gear rack transmission assembly 9 includes a bevel gear 901 fixed on the outer wall of one side of the long board 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 gear 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. 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 rotary motion of the helical gear shaft 902 is transmitted to the nut pair 1003 through the belt transmission structure 903; The screw rod depth adjustment structure 10 includes a nut pair 1003 rotatably mounted at the center position of the top end of the slide 8, a guide column 1001 slidably mounted at the corner position of the top end of the slide 8, and a top plate 1002 fixed at the top end of the four guide columns 1001. A hollow threaded shaft 1004 is installed inside the nut pair 1003. The top end 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 end 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. In 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. 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 main unit of the water quality monitor. During this process, a surplus of the cable is left for the full-spectrum water quality sensor 12 and the support plate 11 to move downward. 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.

[0022] Embodiment 4, based on embodiment 3, Fig.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, and 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 rises and falls, the float unit 403 can float freely, thereby dynamically adjusting the buoyancy to ensure that the device can maintain balance under different water levels, thereby reducing violent shaking or displacement of the device and ensuring that the sensor can stably maintain a predetermined depth.

[0023] 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 to be monitored for water quality. The floating platform 1 serves as the basic supporting structure of the entire device, which can make the device 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 with 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 rotary 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 a sufficient 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 moving 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.
