It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0030] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0031] The following further describes the present utility model in conjunction with the Figure 1-8 accompanying drawings.

[0032] To solve the problems existing in the background art, the present application proposes the following technical solution: It includes a base 1, a vertical rod 2 is fixedly installed on the base 1, an installation plate 3 is fixedly connected to the outer wall of the vertical rod 2. The installation plate 3 provides installation conditions for the monitoring instrument. A water level detector 14 is fixedly installed at the bottom of the installation plate 3. The water level detector 14 is used to detect the water level change of the water area section in real time. A protection frame 15 is also fixedly connected to the bottom of the installation plate 3. A sediment analyzer 16 is fixedly installed in the protection frame 15. The protection frame 15 protects the sediment analyzer 16 from being damaged. The sediment analyzer 16 is used to analyze the content of the collected sediment samples. A controller 6 and a data memory 7 are fixedly installed on the side of the installation plate 3. The data memory 7 is used to record and transmit the analyzed data. An installation hole 12 is formed in the installation plate 3. A threaded rod 4 is slidably installed in the installation hole 12. A sediment collection cylinder 5 is fixedly installed at the bottom of the threaded rod 4. A driving mechanism is also provided on the installation plate 3. The driving mechanism is used to drive the threaded rod 4 to move. The threaded rod 4 drives the sediment collection cylinder 5 to move to collect sediments at different depths.

[0033] The water level detector 14 is electrically connected to the controller 6. The water level detector 14 detects the water level change of the water area section in real time and sends the detected water level data to the controller 6. The water level detector 14 can adopt water level sensors such as ultrasonic and radar. The controller 6 calculates the water change amount according to the received water level data and controls the driving mechanism to make corresponding adjustments to collect sediments at different depths. The collected sediment samples are sent to the sediment analyzer 16 for analysis. The sediment analyzer 16 can adopt devices such as a laser particle size analyzer and a chemical analyzer to measure the particle size, distribution, and chemical composition of the sediment. The sediment analyzer 16 is electrically connected to the data memory 7. The data analyzed by the sediment analyzer 16 is transmitted to the data memory 7 for recording and storage and is transmitted to the remote monitoring center through the data memory 7. Through the real-time perception of the water level change by the water level detector 14, the monitoring device can automatically adjust the sediment sampling position, automatically analyze the sediment samples, and transmit the data back to the monitoring center, making the sediment monitoring operation simple, the data updated quickly, and meeting the requirements of modern water area environment management.

[0034] The water level detector 14 is a water level monitoring module, the controller 6 is a control module, the sediment analyzer 16 is a sediment content analysis module, the data memory 7 is a data recording and transmission module, and the driving mechanism cooperates with the sediment collection cylinder 5 to form a sediment collection module.

[0035] Furthermore, the driving mechanism includes a driving motor 8 fixedly installed at the bottom of the mounting plate 3 and a turntable 11 rotatably installed on the mounting plate 3. The driving shaft of the driving motor 8 penetrates through the mounting plate 3 and is coaxially and fixedly connected with a driving wheel 9. A belt 10 is sleeved outside the driving wheel 9 and the turntable 11, and the turntable 11 is threadedly connected with the threaded rod 4.

[0036] The driving motor 8 can drive the driving wheel 9 to rotate. The driving wheel 9 drives the turntable 11 to rotate synchronously through the belt 10. The turntable 11 drives the threaded rod 4 to move in the mounting hole 12. By the forward and reverse rotation of the driving motor 8, the threaded rod 4 moves up and down. The threaded rod 4 drives the sediment collection cylinder 5 to move up and down. The controller 6 can control the rotation of the driving motor 8, realizing that the controller 6 controls the sediment collection cylinder 5 to move up and down to sample and collect sediments at different depths, so that the monitoring device can automatically adjust the sediment collection depth, ensuring the representativeness of the sediment samples and providing important data support for the protection and management of the water area ecological environment.

[0037] Furthermore, two groups of limiting grooves 22 are formed on the outer surface of the threaded rod 4, and limiting blocks 13 are slidably installed in both groups of limiting grooves 22. The limiting blocks 13 are fixedly installed in the mounting hole 12.

[0038] The limiting blocks 13 cooperate with the limiting grooves 22 to guide and limit the threaded rod 4, preventing the threaded rod 4 from rotating by itself when the turntable 11 rotates, thereby improving the stability of the threaded rod 4 when moving up and down and the stability of the monitoring device during use.

[0039] Furthermore, a filter screen 24 is fixedly installed at one end of the sediment collection cylinder 5. After the controller 6 controls the sediment collection cylinder 5 to move to the designated position, the water flow drives the suspended sediment floating in the water and moving with the water flow and the bed load sediment moving along the bottom of the water into the sediment collection cylinder 5. The filter screen 24 separates the water flow and the sediment, leaving the sediment inside the sediment collection cylinder 5, thus achieving the effect of sediment collection.

[0040] Furthermore, a sealing box 17 is fixedly connected to the outside of the sediment collection cylinder 5. A micro motor 23 is fixedly installed inside the sealing box 17. A valve shaft 18 is fixedly connected to the driving shaft of the micro motor 23. The valve shaft 18 is rotatably installed in the sediment collection cylinder 5, and a butterfly plate 19 is fixedly connected to the outer surface of the valve shaft 18.

[0041] The sealed box 17 protects the micro motor 23 from water entering and damaging the micro motor 23. The micro motor 23 drives the valve shaft 18 to rotate, and the valve shaft 18 drives the butterfly plate 19 to rotate. When the butterfly plate 19 is in a horizontal position in the sediment collection cylinder 5, the opening of the sediment collection cylinder 5 is in an open state, and water flow and sediment can enter the interior of the sediment collection cylinder 5. When the butterfly plate 19 is in a vertical position in the sediment collection cylinder 5, the opening of the sediment collection cylinder 5 is in a closed state, and water flow and sediment cannot enter the interior of the sediment collection cylinder 5. The controller 6 can control the micro motor 23, so that the controller 6 can control the sediment collection cylinder 5 to move to a specified depth and then open the opening. After the sediment collection is completed, the opening is closed to prevent sediment outside the specified depth from entering the sediment collection cylinder 5 during the movement of the sediment collection cylinder 5 and contaminating the sediment sample, ensuring the accuracy of the sediment sample collected by the sediment collection cylinder 5.

[0042] Further, a sediment analysis groove 20 is provided above the sediment collection cylinder 5. The position of the sediment analysis groove 20 corresponds to that of the protection frame 15. Two groups of rotating rods 29 are rotatably installed on the side wall of the sediment analysis groove 20. A sealing cover 21 is fixedly connected between the two groups of rotating rods 29. The sealing cover 21 is adapted to the sediment analysis groove 20. A torsion spring 30 is sleeved outside the rotating rod 29. Two ends of the torsion spring 30 are respectively fixedly installed on the side wall of the sediment analysis groove 20 and the side surface of the sealing cover 21.

[0043] After the sediment collection in the sediment collection cylinder 5 at the specified depth is completed, the driving mechanism drives the sediment collection cylinder 5 to move upward. After the sediment collection cylinder 5 is removed from the water surface, the water inside the sediment collection cylinder 5 flows out through the filter screen 24. The sediment collection cylinder 5 continues to move upward so that the bottom of the protection frame 15 contacts and presses against the top of the sealing cover 21. The protection frame 15 causes the sealing cover 21 to rotate around the rotating rod 29, opening the sediment analysis groove 20. The protection frame 15 and the sediment analyzer 16 move into the sediment collection cylinder 5. The sediment analyzer 16 analyzes the sediment remaining in the sediment collection cylinder 5. After the analysis is completed, the sediment collection cylinder 5 moves downward. The rotating sealing cover 21 causes the torsion spring 30 to twist. As the sediment collection cylinder 5 moves, the protection frame 15 no longer contacts the sealing cover 21. The twisted torsion spring 30 drives the sealing cover 21 to automatically reverse and close the sediment analysis groove 20 to restore the initial state. The setting of the torsion spring 30 enables the sealing cover 21 to automatically reset, improving the practicability of the device.

[0044] Further, a sludge discharge groove 25 is provided below the sediment collection cylinder 5. An installation cavity 26 is provided inside the sediment collection cylinder 5. The installation cavity 26 is communicated with the sludge discharge groove 25. An electric telescopic rod 27 is fixedly installed in the installation cavity 26. One end of the electric telescopic rod 27 is fixedly connected with a baffle 28.

[0045] The electric telescopic rod 27 can push the baffle 28 to move in the installation cavity 26. The controller 6 can control the electric telescopic rod 27. After the sediment analyzer 16 finishes the analysis, the controller 6 controls the electric telescopic rod 27 to drive the baffle 28 to move leftward, so that the sludge discharge groove 25 is opened. The sediment sample inside the sediment collection cylinder 5 is discharged from the sediment collection cylinder 5 through the sludge discharge groove 25, facilitating the next sampling of the sediment collection cylinder 5 and improving the practicability and convenience of use of the device.

[0046] The specific operation and use are as follows: The water level detector 14 detects the water level change of the water area section in real time, and sends the detected water level data to the controller 6. The controller 6 calculates the water change amount according to the received water level data, and controls the driving motor 8 to rotate. The driving motor 8 drives the driving wheel 9 to rotate, and the driving wheel 9 drives the belt 10 to drive the turntable 11 to rotate synchronously. The turntable 11 drives the threaded rod 4 to move downward in the installation hole 12, and the threaded rod 4 drives the sediment collection cylinder 5 to move downward to a specified depth. The controller 6 controls the micro motor 23 to rotate, and the micro motor 23 rotates the butterfly plate 19 to the horizontal position. The water flow brings the sediment into the sediment collection box. The filter screen 24 separates the water flow and the sediment, leaving the sediment inside the sediment collection cylinder 5. The controller 6 controls the driving motor 8 to move the sediment collection cylinder 5 upward. The bottom of the protection frame 15 contacts and presses against the top of the sealing cover 21. The protection frame 15 makes the sealing cover 21 rotate around the rotating rod 29, opening the sediment analysis groove 20. The protection frame 15 and the sediment analyzer 16 move into the sediment collection cylinder 5. The sediment analyzer 16 analyzes the sediment left in the sediment collection cylinder 5. The data analyzed by the sediment analyzer 16 is transmitted to the data memory 7 for recording and storage and transmitted to the remote monitoring center through the data memory 7.
