[0021] Embodiment 1:

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in some embodiments, a sampling cup 1 is included, a cup cover 2 is threadedly connected to the top opening of the sampling cup 1, a plurality of water inlet holes 3 are constructed on the cup cover 2, a filtering mechanism 4 is arranged between the cup cover 2 and the sampling cup 1, a water outlet valve 5 is fixedly connected to the bottom of the sampling cup 1, a stirring mechanism 6 for stirring is arranged inside the sampling cup 1, and a protection mechanism 7 for protecting the sampling cup 1 is arranged outside the sampling cup 1; a scale 8 is engraved along the length direction mark on the outer wall of the sampling cup 1; the filtering mechanism 4 includes a filter cartridge 401 slidably clamped on the sampling cup 1, a filter screen 402 is fixedly installed on the side wall of the filter cartridge 401, and a round hole 403 is opened at the bottom of the filter cartridge 401; the stirring mechanism 6 includes a rotating rod 601 rotatably connected to the cup cover 2, the rotating rod 601 passes through the filter cartridge 401 and the filter screen 402, a plurality of stirring rods 602 are fixed inside the sampling cup 1, and a horizontal plate 603 is fixed at the other end of the rotating rod 601.

[0023] Specifically: by setting up multiple water inlet holes 3 and filtering mechanisms 4, impurities and pollutants can be effectively prevented from entering the sampling cup 1, ensuring the purity and reliability of the sampled water quality; the threaded connection between the cup cover 2 and the sampling cup 1 ensures good sealing; the stirring mechanism 6 set in the sampling cup 1 can ensure that the water sample is fully mixed and uniform, avoiding possible local concentration differences in the sample, and improving the representativeness and accuracy of the sampling.

[0024] The working principle here is: the user places the sampling cup 1 in the water body, closes the water outlet valve 5, and allows the water sample to enter the sampling cup 1; the water sample can smoothly enter the sampling cup 1 through the multiple water inlet holes 3 on the cup cover 2; when the water sample enters the sampling cup 1, it will pass through the filtering mechanism 4 on the cup cover 2; this filtering mechanism 4 includes a filter cartridge 401 slidably mounted on the sampling cup 1; the side wall of the filter cartridge 401 is fixedly mounted with a filter screen 402, which together constitute an effective filtering system; this system can filter out large particles of impurities in the water sample to ensure the cleanliness of the sampling; after the sampling is completed, the sampling cup 1 is taken out, and the cross bar can be rotated so that the cross bar connected to the cup cover 2 The rotating rod 601 starts working; the rotating rod 601 passes through the filter cartridge 401, and the stirring rod 602 is located inside the sampling cup 1, which can drive the stirring rod 602 to stir; this can ensure that the water sample is fully mixed, avoid possible local concentration differences in the sample, and improve the representativeness and accuracy of the sampling; the water outlet valve 5 can be opened to release the water in the sampling cup 1 for testing, and the outer wall of the sampling cup 1 is engraved with scales 8 along the length direction, which allows the user to accurately measure the volume of the sample, facilitating subsequent analysis and processing; the protection mechanism 7 arranged outside the sampling cup 1 can protect the sampling cup 1 from physical damage from the external environment, ensuring the integrity and stability of the sampling device.

[0025] Embodiment 2:

[0026] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0027] like Figure 1 , Figure 4 As shown, in some embodiments, the protection mechanism 7 includes a protection frame 701 sleeved outside the sampling cup 1, the inner diameter of the protection frame 701 is equal to the outer diameter of the sampling cup 1, and the protection frame 701 is threadedly connected with a bolt 702, and the end of the bolt 702 abuts against the outside of the sampling cup 1; the protection frame 701 is provided with a through hole 703 matching the water outlet valve 5, and the working principle here is: the protection mechanism 7 is composed of the protection frame 701 sleeved outside the sampling cup 1. The inner diameter of this protection frame 701 matches the outer diameter of the sampling cup 1, so the sampling cup 1 can be completely embedded in the protection frame 701, thereby protecting the outer surface of the sampling cup 1 from physical damage from the external environment, such as collision or friction; the protection frame is threadedly connected with a bolt 702, and the end of the bolt 702 abuts against the outside of the sampling cup 1. This design can ensure that the sampling cup 1 is firmly fixed inside the protective frame 701, preventing the cup from shaking or loosening during use, thereby affecting the accuracy of sampling; the protective frame 701 is provided with a through hole 703 that matches the water outlet valve 5. The design of this through hole 703 takes into account the need to open the water outlet valve 5 during the sampling process, so the position and size of the through hole 703 match the water outlet valve 5, ensuring that the water outlet valve 5 can be smoothly operated during the sampling process without being affected by the protective frame 701. It should be noted that: the protective frame 701 is symmetrically fixed with mounting ears, which can be used to tie ropes. When the sampling cup 1 and the protective frame 701 are placed in the water together, they can be recovered by pulling the rope.
