[0001] This utility model relates to the field of water quality monitoring technology, and in particular to a wetland water quality monitoring device. Background Technology

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants, and their changing trends to evaluate the water quality status. The monitoring scope is very broad, including unpolluted and polluted natural water (rivers, lakes, seas, and groundwater) as well as various types of industrial wastewater.

[0003] Chinese utility model patent CN219455595U discloses an artificial wetland water quality monitoring device, including a monitoring device body, a lifting rod, and rotating gears. The monitoring device body houses a rotary motor, and a drive shaft is located on one side of the rotary motor, with the rotary motor movably connected to the drive shaft. Two rotating gears are fixedly connected to the drive shaft, and the lifting rod is located on the side of the two rotating gears that are far apart from each other. A sampling component is located at the bottom of the lifting rod. When the rotary motor is turned on, the drive shaft engages with the gear teeth. As the rotating gears rotate, they drive the lifting rod to move up and down through the gear teeth, thereby changing the height of the sampling component.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: When the above-mentioned device is in use, the length of the lifting rod is limited by the main body of the monitoring device, resulting in a small range of motion for the sampling component at its bottom, which affects the sampling depth.

Detailed Implementation

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-5 As shown in the embodiment of this application, a wetland water quality monitoring device is disclosed, including a connecting frame 10, a retaining ring 13, a driving component 20, and a detection component 40. An installation frame is set on the shore or in the water. The connecting frame 10 is connected to the installation frame. An installation box 11 is set with its opening facing downward and is set on the connecting frame 10. A rotating tube 12 is horizontally rotatably arranged inside the installation box 11. Two retaining rings 13 are fixedly sleeved on the rotating tube 12 at intervals. A conveying hose 14 is wound around the tube body of the rotating tube 12 between the two retaining rings 13. One end of the conveying hose 14 is connected to the rotating tube 12, and the other end is fixedly sleeved with a lifting seat 15. A driving component 20 is set inside the installation box 11 to drive the rotating tube 12 to rotate. The driving component 20 drives the rotating tube 12 to rotate, thereby winding or unwinding the conveying hose 14, so that the lower end of the lifting seat 15 and the conveying hose 14 rise and fall to reach different depths in the wetland water area. The conveying hose 14 can be wound and stored, so that the length of the conveying hose 14 can be relatively long, so that the lower end of the conveying hose 14 can rise and fall a large range, ensuring that the sampling depth can be relatively deep. The bottom of the mounting box 11 has two horizontally spaced guide rods 16 arranged vertically. The lifting seat 15 has two vertically formed guide holes, which are slidably connected to the corresponding guide rods 16. The guide rods 16 restrict the sliding of the lifting seat 15, ensuring its stable lifting and lowering, thus guaranteeing the stability of the lower end of the delivery hose 14. A housing 30 connected to the connecting frame 10 is located on one side of the mounting box 11. The housing 30 contains a detection component 40 for drawing water from the rotating pipe 12 and detecting it. Regular water quality testing enables long-term monitoring of the water quality.

[0030] Specifically, a threaded rod 161 is provided at one end of the guide rod 16, and a threaded hole 162 that mates with the threaded rod 161 is provided at the other end. This allows for the selection of an appropriate number of guide rods 16 during the installation of the wetland water quality monitoring equipment, based on the required detection depth, and the guide rods 16 are connected end to end. A filter screen 17 is provided at the bottom of the lifting seat 15 at the end of the conveying hose 14 to prevent aquatic plants and other impurities from entering the conveying hose 14. A connecting plate 18 is provided at the lower end of both guide rods 16. The connecting plate 18 has two round holes. Bolts are screwed through the round holes into the threaded holes 162 on the lowermost guide rod 16, thereby connecting the connecting plate 18 to the guide rod 16. The connecting plate 18 is used to increase the structural stability of the guide rod 16. Two counterweights 19 are provided on the lifting seat 15 to facilitate the descent of the lifting seat 15, thereby driving the lower end of the conveying hose 14 to descend.

[0031] During setup, the drive assembly 20 includes a drive motor 21 located at the top of the mounting box, a gear 22 on the output shaft of the drive motor 21, and a gear ring 23 on one of the retaining rings 13. The gear ring 23 meshes with the gear 22, and the drive motor 21 drives the gear 22 to rotate, thereby driving the gear ring 23, the retaining ring 13, and the rotating tube 12 to rotate.

[0032] In a specific configuration, the detection component 40 includes a detection unit 41 and a pumping unit 45. The detection unit 41 includes a water tank 42 with an open top, housed within a casing 30. A connecting base 43 is located within the casing 30, and a water quality analyzer 44 is mounted on the connecting base 43. The detection head of the water quality analyzer 44 is located inside the water tank 42. The pumping unit 45 pumps water from the rotating pipe 12 into the water tank 42. The detection unit 41 then detects the water in the water tank 42. The water quality analyzer 44 can be an MDS-S98 type water quality analyzer.

[0033] The pumping unit 45 includes a pumping pipe 46. A fixing hole is provided on the side of the mounting box 11 near the chassis 30. The pumping pipe 46 is installed in the fixing hole. The rotating pipe 12 is rotatably connected to and communicates with the pumping pipe 46. The rotating pipe 12 and the pumping pipe 46 are sealed by a rotary seal. A fixing seat 47 is provided inside the chassis 30. A self-priming pump 48 is installed on the fixing seat 47. The input end of the self-priming pump 48 is connected to the pumping pipe 46, and the outlet end is connected to the outlet pipe 481. The end of the outlet pipe 481 away from the self-priming pump 48 is located above the water tank 42. The self-priming pump 48 pumps water from the rotating pipe 12 into the water tank 42. When the self-priming pump 48 starts, it can draw away the air in the rotating pipe 12 to create a negative pressure, thereby allowing water to flow from the delivery hose 14 and the rotating pipe 12 to the self-priming pump 48. The bottom of the water tank 42 is connected to a drain pipe 49. The lower end of the drain pipe 49 passes through the bottom of the chassis 30 and is equipped with a solenoid valve 491. After the water in the water tank 42 is tested, the solenoid valve 491 is opened, so that the water in the water tank 42 is discharged from the drain pipe 49.

[0034] The operating principle of the wetland water quality monitoring device in this embodiment is as follows: The drive motor 21 is started to drive the gear 22 to rotate, thereby rotating the gear ring 23, the retaining ring 13, and the rotating tube 12. This releases the delivery hose 14, causing the lifting seat 15, the counterweight 19, and the lower end of the delivery hose 14 to descend along the guide rod 16. Then, the self-priming pump 48 is started, drawing water from the rotating tube 12 into the outlet pipe 481 via the pumping pipe 46, which then falls into the water tank 42. At this time, the solenoid valve 491 is open, allowing the water pumped into the water tank 42 to be discharged, thus expelling water from other depths in the delivery hose 14. After the self-priming pump 48 has been running for a period of time, the solenoid valve 491 closes, and water begins to accumulate in the water tank 42. The water quality analyzer 44 tests the water in the water tank 42. After the test is completed, the solenoid valve 491 opens, and the water in the water tank 42 is discharged from the drain pipe 49. By conducting regular water quality tests, long-term dynamic monitoring of the water quality is achieved.

[0035] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
