Description

Technical Field

[0001] This invention relates to the field of water quality monitoring technology, and specifically to a water quality monitoring instrument based on continuous monitoring technology. Background Technology

[0002] Water quality monitoring is the process of monitoring and measuring the types, concentrations, and trends of pollutants in water bodies to evaluate water quality. The monitoring scope is very broad, including unpolluted and polluted natural water (rivers, lakes, seas, and groundwater) as well as various industrial wastewater. The main monitoring items can be divided into two categories: one is comprehensive indicators reflecting water quality, such as temperature, color, turbidity, pH, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand (COD), and biochemical oxygen demand (BOD); the other is toxic substances, such as phenols, cyanides, arsenic, lead, chromium, cadmium, mercury, and organochlorine pesticides, for external monitoring. In addition to the monitoring items mentioned above, it is sometimes necessary to measure flow velocity and flow rate to evaluate the water quality of rivers and oceans. The working principle of water quality analyzers is based on different measurement technologies and sensors. Common measurement technologies include electrochemical methods, optical methods, chromatographic methods, and fluorescence methods. Each technology has specific sensors or probes used to measure different indicators in water, such as pH value, dissolved oxygen, conductivity, turbidity, residual chlorine, and ammonia nitrogen. These sensors measure the specific properties or reactions of target substances in the water body by contacting or immersing them in the water sample, and then convert the measurement results into numerical displays or outputs.

[0003] Current water quality monitoring instruments typically use floats to stay afloat on the water surface and are secured by steel cables or anchors to monitor the water quality of a specific area. However, because the instrument remains in a fixed position during monitoring, the monitoring area is relatively limited, and the water samples collected are somewhat homogeneous compared to samples from the entire water body. Therefore, the accuracy of the monitoring results needs improvement. We propose a water quality monitoring instrument based on continuous monitoring technology, which allows for adjustment of the instrument's position, expanding the monitoring range and ensuring greater accuracy. Summary of the Invention

[0015] A winding shaft, which is rotatably disposed at the bottom of the float;

[0016] A pull rope is wound around the outside of the take-up shaft, and the end of the pull rope is fixedly connected to the protective net.

[0017] The monitoring probe is electrically connected to the electrical control box via a spring wire.

[0018] To clean the exterior of the protective netting, a cleaning assembly is also included. This cleaning assembly is used to clean the protective netting and includes:

[0019] A drive ring, which is rotatably disposed outside the protective net;

[0020] A sweeping bar, which is rotatably connected to the drive ring;

[0021] A brush bar, wherein multiple brush bars are provided, and the brush bars are fixedly connected to the outside of the sweeping bar.

[0022] To ensure stability during the monitoring process, a limiting component is also included, which includes:

[0023] A lifting shaft, which is rotatably mounted on the protective net;

[0024] A take-up chain, the take-up chain being wound around the lifting shaft;

[0025] An anchor, which is fixedly connected to the end of the winding chain.

[0026] To enable the rotation of the drive ring and the lifting shaft, a drive assembly is also included, the drive assembly comprising:

[0027] A drive shaft is rotatably mounted on the protective net, and the drive ring and the drive shaft are connected in a transmission manner.

[0028] A support frame, which is fixedly connected to the bottom of the protective netting;

[0030] A connecting shaft is provided, which is vertically and vertically mounted on the support frame, and the connecting shaft is connected to the rotating shaft via a transmission connection.

[0031] The clutch connects the connecting shaft to the drive shaft via the clutch.

[0032] To ensure the stability of the anchor, a fixing component is also included. This fixing component is used to secure the lifting shaft and includes:

[0033] A pressure plate, which is connected to the connecting shaft via a connecting frame, and the pressure plate is in contact with the lifting shaft;

[0034] The lifting shaft has anti-slip texture on its exterior.

[0035] To ensure the vertical raising and lowering of the protective net, a telescopic rod is connected between the protective net and the float.

[0036] (III) Beneficial Effects

[0037] Compared with existing technologies, the present invention provides a water quality monitoring instrument based on continuous monitoring technology, which has the following beneficial effects:

[0038] 1. In this invention, the monitoring instrument is floated on the water surface by a float, the direction of the propeller is adjusted by the rotation of the rotating ring, and the rotation of the propeller pushes the float to move, thereby adjusting the position of the monitoring instrument. The position of the monitoring instrument is located by a positioning device to assist in the adjustment of the monitoring instrument's position. The pull rope is wound and unwound by the rotation of the winding shaft, and the protective net sinks under the action of gravity, thereby adjusting the depth of the monitoring probe, thus enabling water quality monitoring in different areas.

[0039] 2. In this invention, a protective net filters large impurities in the water, preventing them from affecting water quality monitoring. A drive shaft drives a drive ring to rotate around the protective net, and a brush rod cleans the surface of the protective net. As the brush rod rotates around the protective net, it contacts the net, causing the brush rod to rotate. Brush rods at different positions contact the protective net, preventing impurities from accumulating between the net and the brush rod, and ensuring that water passes through the protective net normally.

[0040] 3. In this invention, the clutch is engaged and disengaged by raising and lowering the connecting shaft. When the clutch is engaged, the connecting shaft and the drive shaft are connected, and the drive shaft drives the connecting shaft and the rotating shaft to rotate, thereby winding or unwinding the winding chain. This allows the anchor to fall to the bottom of the water to fix the position of the monitoring instrument, or to retract the anchor so that the float moves under the action of the propeller. At the same time, when the connecting shaft rises and is connected to the drive shaft, the pressure plate moves away from the lifting shaft to avoid obstructing the rotation of the lifting shaft. When the connecting shaft descends and the clutch disengages, the pressure plate presses against the surface of the lifting shaft to fix the winding chain and ensure the stability of the anchor.

[0041] 4. Therefore, compared with existing water quality monitoring instruments, this invention allows the float to move on the water surface through the rotation of the rotating ring and the propeller. This, combined with the positioning device, adjusts the position of the monitoring instrument. The winding of the pull rope by the reel and the gravity of the protective net cause the protective net to move the monitoring probe underwater, adjusting its position for water quality monitoring in different water areas. Simultaneously, the drive shaft drives the drive ring and brush rod to rotate around the protective net, cleaning its surface. The lifting and lowering of the connecting shaft allows the drive shaft to rotate the connecting shaft and lifting shaft, winding or unwinding the reel chain for anchoring or re-anchoring operations, ensuring the float's stability.

[0059] 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.

[0060] Please see Figures 1 to 9A water quality monitoring instrument based on continuous monitoring technology includes a float 1, an electrical control box 2, and a monitoring probe 3. The float 1 allows the electrical control box 2 to float on the water surface, while the monitoring probe 3 is located underwater to monitor various water quality data. The electrical control box 2 is mounted on top of the float 1, and a solar panel 4 and a matching battery are installed on the top of the electrical control box 2 to power the electrical control box 2 and various electrical components in the water quality monitoring instrument based on continuous monitoring technology. It also includes a navigation mechanism and a protective net 5. Compared with existing water quality monitoring instruments, this invention allows the float 1 to move on the water surface through the rotation of the rotating ring 101 and the propeller 103. In conjunction with the positioning device 104, the position of the monitoring device is adjusted. Through the winding shaft 201 winding the pull rope 202 and the gravity of the protective net 5, the protective net 5 drives the monitoring probe 3 to rise and fall underwater, adjusting the position of the monitoring probe 3 to monitor water quality in different water areas. At the same time, the drive shaft 501 drives the drive ring 301 and the brush rod 303 to rotate around the protective net 5, cleaning the surface of the protective net 5. The lifting and lowering of the connecting shaft 504 allows the drive shaft 501 to drive the connecting shaft 504 and the lifting shaft 401 to rotate, winding or unwinding the winding chain 402, and performing anchoring 403 or anchoring 403 to ensure the stability of the float 1.

[0061] In practical applications, historical measurement data from water quality meters are used to establish a time-series-based virtual meter model. Laboratory test data is then used to intelligently calibrate the meter model, improving its accuracy. Furthermore, the establishment of the virtual meter model enables the judgment and early warning of the current health status of water quality meters, achieving intelligent identification of meter health status. This, in turn, scientifically guides the operation and maintenance of meters, contributing to energy conservation and consumption reduction in the construction of smart water systems.

[0062] The navigation mechanism is used to drive the float 1 to move on the water surface. The navigation mechanism includes a rotating ring 101, a mounting frame 102, a propeller 103, and a positioning device 104. The rotating ring 101 is rotatably mounted on the bottom of the float 1. A motor 105 is installed inside the float 1. The output end of the motor 105 passes through the float 1 and is fixedly connected to a drive gear 106. A driven gear ring 107 is fixedly fitted on the outside of the rotating ring 101. The driven gear ring 107 meshes with the drive gear 106. The mounting frame 102 is fixedly connected to the bottom of the rotating ring 101. The propeller 103 is rotatably mounted on the mounting frame 102. A motor 108 is mounted on the mounting frame 102. The propeller 103 is fixedly connected to the output end of the motor 108. A protective cover is fixedly connected to the mounting frame 102. The second motor 108 is located inside the protective cover to prevent direct contact with water and damage. The positioning device 104 is installed on the electrical control box 2. The first motor 105 drives the drive gear 106 to rotate, which in turn drives the driven gear ring 107 and the rotating ring 101 to rotate, adjusting the angle of the propeller 103. The second motor 108 drives the propeller 103 to rotate, providing power for the float 1 to move forward. The positioning device 104 positions the float 1, allowing the operator to monitor and record the position and adjust the position of the float 1. The rotating ring 101 rotates within a 360-degree range, that is, within one revolution, adjusting the angle of the propeller 103 while preventing the wiring of the second motor 108 from getting tangled.

[0063] The monitoring probe 3 is installed inside the protective net 5, which is vertically adjustable at the bottom of the float 1. The monitoring probe 3 rises and falls with the protective net 5. To achieve the lifting and lowering of the protective net 5, a lifting drive component is also included. The lifting drive component is used to drive the protective net 5 to rise and fall. The lifting drive component includes a winding shaft 201 and a pull rope 202. The winding shaft 201 is rotatably installed at the bottom of the float 1. A motor 203 is installed inside the float 1. The output end of the motor 203 passes through the float 1 and is fixedly connected to a drive bevel gear 204. A driven bevel gear 205 is coaxially fixedly connected to the winding shaft 201. The driven bevel gear 205 and the drive bevel gear 204 mesh. The pull rope 202 is wound around the outside of the winding shaft 201, and the end of the pull rope 202 is fixedly connected to the protective net 5. The monitoring probe 3 is electrically connected to the electrical control box 2 via a spring wire to ensure the vertical lifting of the protective net 5. A telescopic rod 206 connects the protective net 5 and the float 1. Motor 203 drives the drive bevel gear 204 to rotate, which in turn drives the driven bevel gear 205 and the winding shaft 201 to rotate, winding and unwinding the pull rope 202. When the pull rope 202 is unwinding, it sinks under the weight of the protective net 5. When the pull rope 202 is winding, it lifts the protective net 5, thus adjusting the height of the monitoring probe 3 for water quality monitoring at different depths. The telescopic rod 206 is a multi-stage telescopic rod 206, which can freely extend and retract with the rise and fall of the protective net 5, ensuring the vertical rise and fall of the protective net 5 and its stability. The extension and retraction of the spring wire can accommodate the rise and fall of the monitoring probe 3 with the protective net 5. Seals are installed at the points where the output ends of motor 105 and motor 203 pass through the float 1 to prevent water from entering the interior of the float 1.

[0064] To clean the exterior of the protective net 5, a cleaning assembly is also included. This assembly includes a drive ring 301, a cleaning rod 302, and brush rods 303. The drive ring 301 is rotatably mounted on the exterior of the protective net 5. The cleaning rod 302 is rotatably connected to the drive ring 301. Multiple brush rods 303 are fixedly connected to the exterior of the cleaning rod 302. The drive ring 301 drives the cleaning rod and brush rods 303 to revolve around the protective net 5. During this revolve, the brush rods 303 contact the surface of the protective net 5. The reaction force of the protective net 5 on the brush rods 303 drives the cleaning rods 302 to rotate, ensuring that brush rods 303 at different positions contact the protective net 5. This prevents impurities from accumulating between the protective net 5 and the brush rods 303. The brush rods 303 clean the surface of the protective net 5, preventing impurities from clogging the mesh and ensuring normal water flow, thereby reducing the impact on water quality monitoring.

[0065] To ensure stability during the monitoring process, a limiting component is also included. The limiting component includes a lifting shaft 401, a winding chain 402, and an anchor 403. The lifting shaft 401 is rotatably mounted on the protective net 5. The winding chain 402 is wound around the lifting shaft 401. The anchor 403 is fixedly connected to the end of the winding chain 402. By rotating the lifting shaft 401, the winding chain 402 can be wound and unwound, thereby releasing and retracting the anchor 403. The anchor 403 descends to the bottom of the water to fix the float 1, ensuring the stability of the float 1 and enabling water quality monitoring at different depths in the water area.

[0066] To enable the rotation of the drive ring 301 and the lifting shaft 401, a drive assembly is also included. The drive assembly includes a drive shaft 501, a support frame 502, a rotating shaft 503, a connecting shaft 504, and a clutch. The drive shaft 501 is rotatably mounted on the protective net 5. A protective cover is fixedly connected to the protective net 5, and a motor 505 is installed inside the protective cover. The drive shaft 501 is fixedly connected to the output end of the motor 505. The drive ring 301 and the drive shaft 501 are connected in a transmission connection. A drive gear 506 is fixedly connected to the end of the drive shaft 501. A driven gear ring 507 is fixedly fitted onto the outside of the rotating ring 101, meshing with the drive gear 506. The support frame 502 is fixedly connected to the bottom of the protective net 5. The lifting shaft 401 rotates via the rotating shaft 503. Connected to support frame 502, connecting shaft 504 is vertically adjustable on support frame 502. Electric cylinder 508 is mounted on support frame 502. Connecting shaft 504 is rotatably connected to the output end of electric cylinder 508. A protective cover is fixedly connected to support frame 502, with electric cylinder 508 located inside the protective cover to prevent damage from water contact. Connecting shaft 504 and rotating shaft 503 are drive-driven. Rotating ring 509 is rotatably connected to support frame 502, and driving bevel gear 510 is fixedly connected to rotating ring 509. Driven bevel gear 513 is fixedly connected to the end of rotating shaft 503. Driving bevel gear 510 and driven bevel gear 513 mesh. Connecting shaft 504 passes through rotating ring 509. A portion of driving bevel gear 510 is provided for connecting shaft 504. 4. A sliding hole is passed through the shaft, and a limit block is fixedly connected inside the sliding hole. A limit groove matching the limit block is opened on the connecting shaft 504. The connecting shaft 504 is connected to the drive shaft 501 through a clutch. The clutch includes two half clutches 511. The bottom of the protective net 5 is rotatably connected to the drive shaft 512. The drive shaft 512 is connected to the drive shaft 501 through a sprocket and chain. One half clutch 511 is connected to the end of the drive shaft 512 through a compression spring and a telescopic rod 206. The other half clutch 511 is fixedly connected to the end of the connecting shaft 504. When the two half clutches 511 are engaged, the drive shaft 501 and the drive gear 506 can be rotated by the motor 505, thereby driving the driven gear ring 507 and the drive ring 301 to rotate, thus driving the cleaning. Rod 302 and brush rod 303 rotate around the protective net 5. Brush rod 303 cleans the outside of the protective net 5. When anchoring 403 or anchoring 403 needs to be deployed or retracted, electric cylinder 508 drives connecting shaft 504 to rise. Two half-clutches 511 engage, and under the action of sprockets and chains, drive shaft 501 drives transmission shaft 512 to rotate. Transmission shaft 512 drives connecting shaft 504 to rotate through clutches, thereby driving active bevel gear 510 to rotate. Active bevel gear 510 drives passive bevel gear 513, rotating shaft 503, and lifting shaft 401 to rotate, thereby winding or unwinding the winding chain 402 to achieve anchoring 403 or anchoring 403. When anchor 403 rises to its highest point to move float 1, or when anchor 403 contacts the bottom of the water to fix float 1,Electric cylinder 508 drives connecting shaft 504 to descend, disengaging the two semi-clutches 511 and stopping the drive of transmission shaft 512 on connecting shaft 504, thus stopping the rotation of lifting shaft 401.

[0067] To ensure the stability of anchor 403, a fixing component is also included. This component secures the lifting shaft 401 and includes a pressure plate 601. The pressure plate 601 is connected to the connecting shaft 504 via a connecting frame 602. The pressure plate 601 and connecting frame 602 are fixedly connected, while the connecting frame 602 and connecting shaft 504 are rotatably connected. The pressure plate 601 contacts the lifting shaft 401. The exterior of the lifting shaft 401 is provided with anti-slip texture 603. The support frame 502 has an opening for raising and lowering the pressure plate 601. When anchor 403 is being lowered or retracted, the electric cylinder 508 drives the connecting shaft 504 upward, engaging two semi-clutches 511. The transmission shaft 512 then drives the connecting shaft 504. At this time, the connecting shaft 504 drives the connecting frame 602 and pressure plate 601 upward, moving the pressure plate 601 away from the lifting shaft 401, allowing the lifting shaft 401 to move with the connecting shaft 501. As anchor 403 rotates, when anchor 403 reaches the bottom or is raised to its highest position, electric cylinder 508 drives connecting shaft 504 to descend, causing the two semi-clutches 511 to disengage. Connecting shaft 504 and winding shaft 201 stop rotating. At the same time, connecting shaft 504 drives pressure plate 601 to descend. Pressure plate 601 presses against the surface of winding shaft 201 to fix winding shaft 201 and ensure the stability of anchor 403. Meanwhile, during the process of monitoring water quality at different depths by raising and lowering protective net 5, anchor 403 is located at the bottom of the water and fixes float 1. While winding shaft 201 winds or unwinds pull rope 202, lifting shaft 401 winds or unwinds winding chain 402, keeping the distance between float 1 and anchor 403 within a certain range. This prevents the distance between anchor 403 and float 1 from increasing and causing the float 1 to move more widely when protective net 5 descends.

[0068] The working principle or usage process of the water quality monitor based on continuous monitoring technology is as follows: The monitor is placed in the water area to be monitored. Under the action of float 1, the monitor floats on the water surface. Positioning device 104 locates the monitor. Motor 105 drives drive gear 106 to rotate, thereby driving driven gear ring 107 and rotating ring 101 to rotate, adjusting the angle of propeller 103, which in turn adjusts the direction of float 1's movement. Motor 2 108 drives propeller 103 to rotate, driving float 1 to move. After moving to the monitoring position, motor 2 108 stops rotating. Electric cylinder 508 drives connecting shaft 504 to rise, engaging two semi-clutches 511. Motor 4 505 drives drive shaft 501 to rotate, which in turn drives drive gear 506 and rotating ring 101 to rotate, causing brush rod 303 to move towards the outside of protective net 5. While cleaning, drive shaft 501 drives transmission shaft 512 to rotate, which in turn drives connecting shaft 504 and lifting shaft 401 to rotate, unwinding the winding chain 402 and lowering anchor 403 to the bottom of the water to secure float 1. Then, motor 3 203 drives winding shaft 201 to rotate, unwinding pull rope 202 and adjusting the height of protective net 5, allowing monitoring probe 3 to monitor water quality at different depths. As protective net 5 rises and falls, motor 4 505 drives lifting shaft 401 to rotate, winding or unwinding winding chain 402. This, combined with the rise and fall of protective net 5, keeps the distance between anchor 403 and float 1 within a suitable range. Using historical measurement data from monitoring probe 3, a time-series-based virtual instrument model is established, and laboratory test data is used to intelligently calibrate the instrument model, improving its accuracy. Simultaneously, the model assesses and warns of the current health status of the water quality instrument, achieving intelligent identification of instrument health status.
