Description

Technical Field

[0001] This application relates to the field of water quality monitoring equipment technology, and in particular to an online water quality monitoring device. Background Technology

[0002] The isolated water quality online monitoring equipment serves as the "eyes and ears" and "early warning system" for water environment supervision. Its core function is to provide accurate data support for water quality safety management through real-time, continuous, and automated monitoring. It can dynamically detect key indicators in water bodies such as pH value, dissolved oxygen, chemical oxygen demand, ammonia nitrogen, heavy metal ions, and algae concentration, and can promptly capture abnormal fluctuations in water quality. In addition, the equipment transmits data to the monitoring platform in real time through Internet of Things (IoT) technology, forming visualized water quality change curves and trend analyses. This helps environmental protection departments and water conservancy agencies to understand the water quality status of a basin or region, providing a scientific basis for tracing pollution sources and formulating water environment governance plans.

[0003] Existing online water quality monitoring equipment can extract water from sources at different depths during practical use. However, rain or strong sunlight can cause the water source height to shift. Since existing equipment cannot determine the water source height, there is uncertainty in the water source height when extracting water from sources at different depths, which reduces the detection accuracy. In addition, in actual use, the online water quality monitoring equipment is inserted into the water, and the fluidity of the water source seriously affects the water source monitoring and makes it impossible to detect the direction of water flow. Therefore, we propose an online water quality monitoring device. Utility Model Content

This utility model, through the coordinated action of a lifting rope, a lifting motor, and a lifting angle sensor, can automatically adjust the position of the detection frame according to the water source height. When the water source height changes due to rain or strong sunlight, the lifting angle sensor monitors the rotation angle of the lifting cylinder in real time and accurately calculates the release length of the lifting rope, ensuring that the detection shell is always at the target detection depth.

Simultaneously, the protective rope and spiral spring inside the protective shell stabilize the posture of the detection frame. When the water flows, the flow direction plate rotates with the water flow, the direction angle sensor provides real-time feedback on the flow direction data, and the protective rope, under the action of the spiral spring, keeps the detection frame stable, reducing interference from water flow fluctuations. This achieves both water flow direction monitoring and ensures the accuracy and reliability of the water quality sensor's detection data. Attached Figure Description

[0023] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0024] This application discloses an online water quality monitoring device. For example... Figure 1As shown, it includes a fixed rod 1, with a lifting rope 2 slidably connected inside the fixed rod 1 for lifting the water intake device. A protective shell 3 is fixedly connected to the output end of the lifting rope 2 for stabilizing the water intake device and improving the water intake accuracy. A lifting shell 6 is fixedly installed on the outside of the fixed rod 1 for driving the lifting rope 2 and protecting the lifting rope 2.

[0025] Please see Figure 4 One end of the lifting rope 2 is fixedly connected to a detection frame 4. The bottom of the detection frame 4 is fixedly connected to a bottom ring 29. A direction angle sensor 30 is fixedly installed on the top of the bottom ring 29. A flow direction plate 31 is fixedly connected to the detection end of the direction angle sensor 30. The flow direction plate 31 is rotatably connected to the bottom of the bottom ring 29. The direction of water flow can be detected by the direction angle sensor 30 and the flow direction plate 31.

[0026] Please see Figure 4 and Figure 5 The inside of the detection frame 4 is slidably connected to a buoyancy airbag 14, which can float on the water surface and release the water collection device based on the water surface. The inside of the buoyancy airbag 14 is fixedly connected to a drive shell 15, and a drive rope 16 is provided inside the drive shell 15, which extends to the outside of the drive shell 15.

[0027] A drive frame 17 is fixedly connected to the inner wall of the drive housing 15. A drive cylinder 18 is rotatably connected inside the drive frame 17. A drive rope 16 is wound around the outside of the drive cylinder 18. A drive motor 19 is fixedly installed at the bottom of the inner wall of the drive housing 15. A drive angle sensor 20 is fixedly installed at the top of the drive housing 15. The output ends of the drive motor 19 and the drive angle sensor 20 are rotatably connected to the same synchronous belt 21. The output end of the drive motor 19 is fixedly connected to one end of the drive cylinder 18. The drive angle sensor 20 is used to detect the water intake height of the water intake device to improve the accuracy of water intake detection.

[0028] Please see Figure 4 and Figure 6 The detection frame 4 has a detection shell 5 that is slidably connected inside. A water quality sensor 28 is fixedly installed on the inner wall of the detection shell 5 for detecting the collected water quality. A sealing head 23 is slidably connected inside the drive shell 15. The top of the sealing head 23 is fixedly connected to one end of the drive rope 16. A linkage rod 27 is fixedly connected to the bottom of the sealing head 23. A discharge head 26 is fixedly connected to the bottom of the linkage rod 27. Both the sealing head 23 and the discharge head 26 are adapted to the drive shell 15. The linkage rod 27 is used to drive the sealing head 23 and the discharge head 26 simultaneously.

[0029] A sealing shell 22 is fixedly connected to the top of the inner wall of the detection shell 5. A sealing head 23 is slidably connected inside the sealing shell 22. A sealing spring 24 is fixedly connected to the top of the sealing head 23. The top of the sealing spring 24 is fixedly connected to the top of the inner wall of the detection shell 5. A discharge groove 25 is opened at the bottom of the inner wall of the detection shell 5. A discharge head 26 is slidably connected inside the discharge groove 25. The sealing spring 24 is used to drive the sealing head 23 and the discharge head 26 to seal the detection shell 5.

[0030] Please see Figure 1 and Figure 2 The lifting shell 6 is rotatably connected to the lifting cylinder 8, and the protective shell 3 is wound around the outside of the lifting cylinder 8. A lifting motor 7 is fixedly installed on one side of the lifting shell 6, and the output end of the lifting motor 7 is fixedly connected to one end of the lifting cylinder 8. A lifting angle sensor 9 is fixedly installed on one side of the lifting shell 6, and the detection end of the lifting angle sensor 9 is fixedly connected to one end of the lifting cylinder 8. The lifting angle sensor 9 is used to detect the length of the released lifting rope 2 to improve the water intake accuracy.

[0031] Please see Figure 1 and Figure 3 A protective frame 10 is fixedly connected inside the protective shell 3. A protective cylinder 11 is rotatably connected inside the protective frame 10. A protective rope 12 is wound around the outside of the protective cylinder 11. One end of the protective rope 12 is fixedly connected to the top of the detection frame 4. A spiral spring 13 is fixedly connected to the outside of the protective cylinder 11. One end of the spiral spring 13 is fixedly connected to the inner wall of the protective shell 3. The protective rope 12 is used to improve the stability of the detection frame 4 and improve the detection accuracy of the detection frame 4.

[0032] The implementation principle of an online water quality monitoring device in this application embodiment is as follows: When water quality needs to be tested, the output end of the lifting motor is started for 7 seconds to drive the lifting cylinder 8 to rotate. The rotation of the lifting cylinder 8 drives the lifting rope 2 to extend, thereby raising and lowering the detection frame 4. At the same time, the lifting angle sensor 9 is started. The detection end of the lifting angle sensor 9 follows the rotation of the lifting cylinder 8 and detects the length of the lifting rope 2.

[0033] During the process of raising and lowering the testing frame 4 into the water, the protective rope 12 extends from the outside of the protective cylinder 11 and causes the spiral spring 13 to be compressed, which improves the tilt stability of the testing frame 4. It is worth mentioning that the longer the protective rope 12 extends, the more the spiral spring 13 is compressed, the higher the control of the testing frame 4, and the more it prevents the testing frame 4 from drifting with the water flow.

[0034] The drive motor 19 is activated based on the desired water depth. The output of the drive motor 19 rotates, causing the drive cylinder 18 to rotate. The rotation of the drive cylinder 18 extends the drive rope 16. Simultaneously, the rotation of the drive motor 19's output drives the synchronous belt 21 to rotate, and the extension length of the drive rope 16 is detected by the drive angle sensor 20. When the desired water depth is reached, the drive motor 19 is turned off, and the detection frame 4 is then placed in the water. During this process, the buoyancy airbag 14 floats on the water surface. When the detection shell 5 reaches the desired water depth, the drive rope 16 is taut, and the detection shell 5 continues to move within the detection frame 4. The sealing spring 24 is compressed, and the sealing head 23 slides inside the sealing spring 24. It also drives the discharge head 26 to slide through the linkage rod 27. Water enters the interior of the detection shell 5 through the sealing shell 22 and the discharge channel 25. At this time, it can be detected by the water quality sensor 28. When it is necessary to move the detected water, the drive motor 19 extends the drive rope 16 again, so that the sealing head 23 and the discharge head 26 can cooperate with the sealing shell 22 and the discharge channel 25 respectively. When it is not necessary to move it out, the drive motor 19 is started to pull the detection shell 5 directly out of the water surface. The water inside the detection shell 5 can then flow out through the discharge channel 25 for the next detection.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
