Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-4 An embodiment of this utility model is provided: a water organic matter sampling and detection device, including a sampling bucket 1, a swinging component connected to the outer wall of the sampling bucket 1, a detachable filter component connected to the inside of the sampling bucket 1, and a detachable stirring component connected to the side of the swinging component.

[0032] The swing assembly includes a fixed block 3, which is fixedly connected to the outer wall of the sampling barrel 1. A drive motor 4 is fixedly connected to the side of the fixed block 3. A threaded rod 5 is fixedly connected to the output end of the drive motor 4. A movable block 9 is threadedly connected to the outer wall of the threaded rod 5. A guide rod 25 is fixedly connected to the side of the fixed block 3. The movable block 9 slides outside the guide rod 25. A sliding rod 10 is fixedly connected to the side of the movable block 9. A fixed rod 6 is rotatably connected to the outer wall of the sampling barrel 1. A drive plate 7 is fixedly connected to one end of the fixed rod 6. A groove 8 is opened in the drive plate 7. The sliding rod 10 slides in the groove 8 to facilitate the rotation of the drive plate 7.

[0033] The detachable stirring assembly includes a stirring rod 22, which is slidably connected to a fixed rod 6. Both the fixed rod 6 and the stirring rod 22 have through grooves 20, through which a fixing bolt 21 passes. A nut 26 is threaded onto the outer wall of the fixing bolt 21. A stirring plate 23 is fixedly connected to the outer wall of the stirring rod 22, and multiple sets of stirring plates 23 are provided. The detachable filter assembly includes a filter plate 19, which slides within a sampling container 1. A vertical groove 14 is provided on the inner wall of the sampling container 1. A spring 15 is fixedly connected to the bottom of the vertical groove 14, and a top block 16 is fixedly connected to the top of the spring 15. The top block 16 slides within the vertical groove 14. A sliding plate 17 is fixedly connected to the outer wall of the filter plate 19, and the sliding plate 17 slides within the vertical groove 14. The sampling bucket 1 is rotatably connected to a baffle 18 at its top; a limiting block 11 is fixedly connected to the top of the sampling bucket 1, and a top cover 12 is connected to the top of the sampling bucket 1. A slot 13 is opened in the top cover 12, and the slot 13 is slidably connected to the limiting block 11; a support leg 2 and a connecting plate 24 are fixedly connected to the bottom of the sampling bucket 1. Multiple sets of support legs 2 are provided, and a mass spectrometer is connected to the top of the connecting plate 24; a water pump is connected to the outside of the sampling bucket 1, and an inlet pipe is connected to the water pump inlet, which extends into the sampling bucket 1. A hose is connected to the water pump outlet, which extends into the mass spectrometer; a threaded rod 5 is parallel to the guide rod 25, which facilitates the swinging motion of the stirring plate 23 to stir the water sample in the sampling bucket 1.

[0034] Working principle: In the water organic matter sampling and detection device, the drive motor 4 is started to drive the threaded rod 5 to rotate. The threaded rod 5 drives the moving block 9 to slide along the guide rod 25, which in turn drives the slide rod 10 to slide in the slide groove 8. This causes the drive plate 7 to swing, which in turn causes the fixed rod 6 to swing. This facilitates the swinging of the stirring plate 23 to stir the water sample in the sampling bucket 1, preventing sedimentation or stratification that could lead to inaccurate test results. The nut 26 is unscrewed from the outside of the fixing bolt 21, and the fixing bolt 21 is pulled out of the through groove 20. This makes it easy to disassemble, clean, or replace the stirring plate 23 without affecting the subsequent stirring effect. Rotating the baffle 18 releases the limit on the slide plate 17, causing the compressed spring 15 to lift the top block 16 upward, which in turn causes the slide plate 17 to slide in the vertical groove 14. This makes it easier to disassemble and clean the filter plate 19 that filters impurities from the water sample, making it more convenient for the water sample to enter the mass spectrometer for subsequent detection.

[0035] The mass spectrometer in this application is the same as the mass spectrometer in the authorized patent with publication number CN211603026U. Its structure and working principle are the same, and will not be described again in this application.

[0036] All electrical components mentioned in this article are electrically connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and known components is omitted in the specific embodiments disclosed herein. To ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.
