Description

Technical Field

[0001] This invention is an in-situ water ecology monitoring device, belonging to the field of water ecology monitoring technology. Background Technology

[0002] Water ecological monitoring is a crucial foundation for water resource protection and water environment management. Traditional water quality monitoring methods, which mostly rely on manual sampling or fixed-point buoy monitoring, suffer from problems such as long sampling cycles, poor real-time performance, and difficulty in achieving continuous monitoring of different water layers. Especially in water bodies such as lakes, reservoirs, and rivers, water quality parameters (such as pH, dissolved oxygen, and turbidity) change significantly with water depth and time, making it difficult for traditional single-point sampling to fully reflect the true condition of the water body.

[0003] In addition, existing in-situ monitoring devices often separate the sampling and monitoring processes, making it impossible to integrate in-situ sample sealing with real-time detection, which affects the accuracy and reliability of the data.

[0004] Therefore, a water ecological monitoring device that can achieve multi-depth, automated, in-situ monitoring and sampling integration is provided. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide an in-situ water ecology monitoring device.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: A water ecological in-situ monitoring device includes a floating vessel. A mounting frame assembly is fixedly mounted on the floating vessel. A driving pulley and a driven pulley are movably connected to the front and rear ends of the mounting frame assembly, respectively. One end of the driving pulley is connected to the output end of a servo motor, which is mounted on the mounting frame assembly. The driven pulley is connected to the driving pulley via a belt. One end of the driven pulley is connected to a winding roller, on which a composite traction cable is wound. The end of the composite traction cable is fixedly connected to a monitoring cylinder. A counterweight is mounted at the bottom of the monitoring cylinder. Several sampling cylinders are evenly mounted on the outer circumference of the monitoring cylinder. A sealing cover is rotatably connected to the top opening of each sampling cylinder. The sealing cover and the top opening of the sampling cylinder are sealed together by an opening and closing mechanism, which is installed in a drive chamber inside the monitoring cylinder. A water quality monitoring device is installed in an electrical control chamber inside the monitoring cylinder. Several sensor probes on the water quality monitoring device extend through the bottom of several sampling cylinders.

[0007] Furthermore, the opening and closing mechanism includes a drive assembly and several linkage assemblies. The drive assembly includes a turntable rotatably connected to the center of the bottom of the drive cavity. The center of the bottom of the turntable is connected to the output end of a second servo motor. The second servo motor is installed in the bottom of the drive cavity. A notch is provided on one side of the outer circumference of the turntable. A limiting distance communicating with the notch is provided at the outer edge of the bottom of the turntable. A support plate is fixed on the top of the turntable near the notch. A movable frame is rotatably connected to the top of the support plate via a rotating shaft. A connecting frame and a sliding frame are fixed on both sides of the movable frame, respectively. An arc-shaped abutment plate is fixed to the end of the connecting frame. A sliding sleeve is slidably fitted on the sliding frame. A movable component is movably connected to the bottom of the sliding sleeve. The end of the movable component is fixedly connected to the telescopic end of an electric push rod. The bottom end of the electric push rod is movably connected to the top of the turntable via a movable seat.

[0008] Furthermore, several linkage components correspond one-to-one with several sampling cylinders. The linkage components are fixed at the inner bottom edge of the drive cavity. Each linkage component includes a movable part that is hinged to the inner bottom edge of the drive cavity via a hinge seat. The movable part has a groove adapted to the arc-shaped abutment plate. The side of the movable part is fixed with a limiting part adapted to the notch and the limiting distance.

[0009] Furthermore, a traction rope is fixed to the end of the movable part, the traction rope passes through the monitoring tube to the sampling tube and is connected and fixed to the inner wall of the sealing cover plate, and a protective shell adapted to the traction rope is fixed inside the sampling tube.

[0010] Furthermore, a limiting plate is provided on one side of the top opening of the sampling tube, and a limiting groove is provided on the top side of the outer surface of the sealing cover to fit the limiting plate. A counterweight block two is fixed on the bottom side of the sealing cover and below the limiting groove.

[0011] Furthermore, the water quality monitoring equipment includes any one or more of the following: pH water quality automatic analyzer, dissolved oxygen water quality automatic analyzer, and turbidity water quality automatic analyzer, and the sensor probe includes the sensor monitoring end of the above-mentioned analyzer.

[0012] Furthermore, an angle sensor is installed on the take-up roller, and a power supply, a controller, a memory, and a wireless signal transceiver are provided inside the electrical control cavity. The servo motor one, the servo motor two, the electric push rod, the angle sensor, the power supply, the memory, and the wireless signal transceiver are all electrically connected to the controller.

[0013] The beneficial effects of this invention are: This invention enables water sample collection and in-situ monitoring of water quality parameters at different water layers by uniformly arranging multiple sampling tubes around the monitoring tube and equipping them with independent sealing covers and opening / closing mechanisms. This avoids the limitations of traditional single-point sampling and achieves multi-level synchronous monitoring and sampling.

[0014] This invention controls the lifting and lowering of the monitoring cylinder by driving the take-up roller with a servo motor, and determines the extension distance of the traction rope by combining it with an angle sensor to determine the extension water depth. Furthermore, the opening and closing mechanism is controlled by a servo motor and an electric push rod to open or close the sealing cover on each sampling cylinder as needed, either sequentially or selectively, thus realizing a fully automated sampling and monitoring process.

[0015] In this invention, the sensor probe on the water quality monitoring equipment extends directly into the bottom of the sampling tube, allowing for immediate detection of the water sample after it enters the tube. This avoids parameter changes caused by the transfer of the water sample or exposure to air. Furthermore, the sealing cover remains sealed when not sampling, preventing cross-interference between different water layers.

[0016] The opening and closing mechanism of this invention adopts a mechanical linkage design including a turntable, a movable part, an arc-shaped abutment plate, and a traction rope. Combined with a limiting part, it achieves precise control of multiple sampling tubes. The structure is compact, the operation is reliable, and it is adaptable to complex underwater environments.

[0017] The electrical control cavity of this invention is equipped with a controller, a memory, a wireless signal transceiver and a power supply, which can upload the monitoring data of each sensor to a remote platform in real time, facilitating long-term and continuous water ecological monitoring and data analysis, and realizing remote data transmission and storage.

[0021] 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.

[0022] Please see Figures 1-14 This invention provides a technical solution for an in-situ aquatic ecological monitoring device, comprising a floating vessel 1, on which a mounting frame assembly 2 is fixed. The front and rear ends of the mounting frame assembly 2 are respectively movably connected to a driving pulley 3 and a driven pulley 5. One end of the driving pulley 3 is connected to the output end of a servo motor 4, which is mounted on the mounting frame assembly 2. The driven pulley 5 is connected to the driving pulley 3 via a belt 7. One end of the driven pulley 5 is connected to a winding roller 6, on which a composite traction cable 8 is wound. The end of the traction cable 8 is connected and fixed to the monitoring cylinder 9. A counterweight 10 is installed at the bottom of the monitoring cylinder 9. Several sampling cylinders 11 are evenly installed on the outer circumference of the monitoring cylinder 9. A sealing cover 12 is rotatably connected to the top opening of the sampling cylinder 11. The sealing cover 12 and the top opening of the sampling cylinder 11 are sealed together by an opening and closing mechanism. The opening and closing mechanism is installed in the drive cavity 18 inside the monitoring cylinder 9. A water quality monitoring device 27 is installed in the electrical control cavity 19 inside the monitoring cylinder 9. Several water quality monitoring devices 27 have... Sensor probes 20 extend into the inner bottom of several sampling cylinders 11. The water quality monitoring device 27 includes any one or more of an automatic pH water quality analyzer, an automatic dissolved oxygen water quality analyzer, and an automatic turbidity water quality analyzer. The sensor probes 20 include the sensor monitoring end of the aforementioned analyzers. An angle sensor is installed on the winding roller 6. The aforementioned monitoring instruments are all existing technologies and will not be described in detail. The electrical control cavity 19 is equipped with a power supply, controller, memory, and wireless signal transceiver. The servo motor 4 and the servo motor... Machine 2: The electric push rod 35, the angle sensor, the power supply, the memory, and the wireless signal transceiver are all electrically connected to the controller. In use, the floating boat 1 is placed in the monitored water area. The controller starts the servo motor 4 to drive the active pulley 3 to rotate, which in turn drives the driven pulley 5 via the belt 7, causing the winding roller 6 to rotate, releasing or winding the composite traction cable 8. While extending, the monitoring cylinder 9 sinks to the predetermined water depth under its own weight and the action of the counterweight 10. The angle sensor on the winding roller 6 provides real-time feedback on the length of the released cable, achieving precise depth measurement.

[0023] See Figures 9-13The opening and closing mechanism includes a drive assembly and several linkage components. The drive assembly includes a turntable 24 rotatably connected to the bottom center of the drive cavity 18. The bottom center of the turntable 24 is connected to the output end of a servo motor 2. The servo motor 2 is installed at the bottom of the drive cavity 18. A notch 25 is provided on one side of the outer circumference of the turntable 24. A limiting distance 26 communicating with the notch 25 is provided at the bottom outer edge of the turntable 24. A support plate 28 is fixed to the top of the turntable 24 near the notch 25. A movable frame 29 is rotatably connected to the top of the support plate 28 via a rotating shaft. A connecting frame 30 and a sliding frame 32 are fixed to both sides of the movable frame 29, respectively. An arc-shaped abutment plate 31 is fixed to the end of the connecting frame 30. A sliding sleeve 33 is slidably fitted on the sliding frame 32. The bottom of the sliding sleeve 33 is movably connected to a movable part 34. The end of the movable part 34 is fixedly connected to the telescopic end of the electric push rod 35. The bottom end of the electric push rod 35 is movably connected to the top of the turntable 24 through a movable seat. When the monitoring tube 9 reaches the target water layer, the controller starts the opening and closing mechanism. The servo motor drives the turntable 24 to rotate, so that the notch 25 and the limit distance 26 on the turntable 24 are aligned with the movable part 21 on the sampling tube 11 that needs to be opened. At this time, the arc-shaped abutment plate 31 will rotate into the groove 23 on the movable part 21. Then the electric push rod 35 extends to push the sliding sleeve 33 to slide on the sliding frame 32. At the same time, it drives the movable frame 29, the connecting frame 30 and the arc-shaped abutment plate 31 to rotate downward with the support plate 28 as the fulcrum, thereby abutting and pushing the linkage component, thereby pushing the sealing cover plate 12 on the sampling tube 11 to rotate and open.

[0024] See Figure 10Several linkage components correspond one-to-one with several sampling cylinders 11. The linkage components are fixed at the inner bottom edge of the drive cavity 18. Each linkage component includes a movable part 21 hinged to the inner bottom edge of the drive cavity 18 via a hinge seat. The movable part 21 has a groove 23 adapted to the arc-shaped abutment plate 31. The side of the movable part 21 is fixed with a limiting part 22 adapted to the notch 25 and the limiting distance 26. A traction rope 16 is fixed to the end of the movable part 21. The traction rope 16 passes through the monitoring cylinder 9 to the sampling cylinder 11 and is connected and fixed to the inner wall of the sealing cover plate 12. A protective shell 17 adapted to the traction rope 16 is fixed inside the sampling cylinder 11. The arc-shaped abutment plate 31 on the drive component rotates into the groove 23 on the movable part 21. Then, the electric push rod 35 extends to push the sliding sleeve 33 to slide. The sliding mechanism 32 simultaneously drives the movable frame 29, connecting frame 30, and arc-shaped abutment plate 31 to rotate downwards around the support plate 28. During rotation, the arc-shaped abutment plate 31 pushes the groove 23, causing the movable part 21, which is in an inclined state, to gradually rotate into a vertical state. At the same time, the limiting part 22 on the side of the movable part 21 rotates away from the limiting distance 26 and the notch 25 and disengages from the turntable 24, releasing the locking and limiting state with the turntable 24. As the movable part 21 rotates into a vertical state, the traction rope 16 is gradually extended, thereby releasing the pulling and limiting of the sealing cover plate 12. At this time, the sealing cover plate 12 rotates under its own weight and the action of the counterweight 15, thereby releasing the blockage of the sampling cylinder 11. The water at this depth will enter the sampling cylinder 11. While the sensor probe 20 is monitoring the water quality, the water sample can also be stored, which is convenient for subsequent laboratory monitoring and ensures the accuracy of the monitoring results.

[0025] See Figures 6-7 A limiting plate 13 is provided on one side of the top opening of the sampling cylinder 11. A limiting groove 14 that fits and engages with the limiting plate 13 is provided on the top side of the outer surface of the sealing cover plate 12. Sealing gaskets are provided at the junction of the limiting plate 13 and the limiting groove 14, and at the junction of the sealing cover plate 12 and the opening of the sampling cylinder 11. A counterweight 15 is fixed on one side of the bottom of the sealing cover plate 12 and below the limiting groove 14. With the setting of the counterweight 15, when the traction rope 16 is released to release the pull on the limiting plate 13, the limiting plate 13 flips under the action of the counterweight 15, thereby opening the top opening of the sampling cylinder 11, so that the water in the water layer can enter the sampling cylinder 11 for sample storage and monitoring by the sensor probe 20.

[0026] The heat dissipation holes and maintenance doors in the space of circuits and electronic components, modules and controllers or adapted electrical equipment are all existing technologies that can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve improvements to software and methods or heat dissipation and maintenance.

[0027] In operation, the floating vessel 1 is placed in the monitored water area. The controller starts the servo motor 4, which drives the active pulley 3 to rotate. This drives the driven pulley 5 via the belt 7, causing the winding roller 6 to rotate, releasing or winding the composite traction cable 8. Simultaneously, the monitoring cylinder 9 sinks to the predetermined water depth under its own weight and the action of the counterweight 10. The angle sensor on the winding roller 6 provides real-time feedback on the cable length, achieving precise depth determination. When the monitoring cylinder 9 reaches the target water layer, the controller activates the opening and closing mechanism. The servo motor 2 drives the turntable 24 to rotate, aligning the notch 25 and the limit distance 26 on the turntable 24 with the movable part 21 on the sampling cylinder 11 that needs to be opened. At this time, the arc-shaped abutment plate 31 will rotate into the groove 23 on the movable part 21. Then, the electric push rod 35 extends to push the sliding sleeve 33 to slide on the sliding frame 32, and at the same time drive the movable frame 29, the connecting frame 30 and the arc-shaped abutment plate 31 to rotate downward with the support plate 28 as the fulcrum. During the rotation, the arc-shaped abutment plate 31 will push the groove 23 to make the movable part 21, which is in an inclined state, gradually rotate into a vertical state. At the same time, the limiting part 22 on the side of the movable part 21 will rotate away from the limiting distance 26 and the notch 25 to disengage from the turntable 24 and release the locking and limiting state with the turntable 24. As the movable part 21 rotates into a vertical state... As the traction rope 16 is gradually extended, it releases the tension on the sealing cover 12. At this time, the sealing cover 12 rotates under its own weight and the action of the counterweight 15, thus releasing the seal on the sampling cylinder 11. Water at this depth will enter the sampling cylinder 11. While the sensor probe 20 is monitoring the water quality, water samples can also be stored for subsequent laboratory monitoring, ensuring the accuracy of the monitoring results. After the monitoring is completed, the electric push rod 35 retracts, causing the movable frame 29, the connecting frame 30, and the arc-shaped abutment plate 31 to rotate upward with the support plate 28 as the fulcrum. This causes the movable part 21 and the limiting part 22 to reset and rotate downward, so that the limiting part... The sampling cylinder 22 rotates through the notch 25 to the limiting distance 26 at the bottom of the turntable 24. By driving the turntable 24 to rotate, the notch 25 and the limiting part 22 are misaligned, thus achieving the locking and limiting. At the same time, the traction rope 16 is also pulled into a taut state, thereby pulling the sealing cover 12 to reset and rotate, so that the sealing cover 12 seals and blocks the opening of the sampling cylinder 11. In this way, by controlling the rotation angle of the turntable 24 and coordinating the action of the electric push rod 35, different sampling cylinders 11 can be opened in sequence, thereby sampling and monitoring water layers at different depths. All data is processed and stored by the controller and transmitted to the ground receiving station through the wireless signal transceiver device.

[0028] After monitoring is completed, servo motor 4 reverses, winding roller 6 retracts composite traction cable 8, and lifts monitoring cylinder 9 to the water surface. Staff can then take out water samples from sampling cylinder 11 for laboratory re-inspection or to clean and maintain the device.

[0029] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
