[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A stratified sampling device for river water environment monitoring includes a frame 1. Several snap-fit ​​slots 2 are provided on the front side of the frame 1. Snap-fit ​​blocks 3 are snapped into the inside of the snap-fit ​​slots 2. An extraction component 4 is fixedly connected to the front side of the snap-fit ​​block 3. An adjustment component 5 is provided inside the frame 1 to cooperate with the extraction component 4.

[0027] The extraction component 4 includes a sampling tank 401, with a water inlet 402 at the top of the sampling tank 401. A disc 403 is slidably connected inside the sampling tank 401, and a connecting rod 404 is fixedly connected to the top of the disc 403. An installation sleeve 405 is fitted on the surface of the sampling tank 401 and is bolted to the front side of the snap-fit ​​block 3. A splicing groove 406 is provided at the top of the connecting rod 404.

[0028] In this embodiment: by setting a frame 1 and several snap-fit ​​slots 2, the snap-fit ​​block 3 can contact the inner wall of the snap-fit ​​slot 2, allowing the frame 1 to support the extraction component 4. The extraction component 4 can sample water. By setting an adjustment component 5, the extraction component 4 can be used in conjunction to collect and process water. By setting a sampling tank 401, a water inlet 402, a disc 403, a connecting rod 404, and a mounting sleeve 405, the snap-fit ​​block 3 can be spliced ​​with different snap-fit ​​slots 2 on the front side of the frame 1 as needed. Then, the frame 1 supports the mounting sleeve 405. Then, the user manually connects the sampling tank 401 and the mounting sleeve 405. 5. After the snap-fit ​​is completed, the user places the frame 1 into the river channel to be sampled. Then, the user manually adjusts the adjustment component 5 to adjust the connecting rod 404, thereby adjusting the height of the disc 403 inside the sampling tank 401. Then, under adjustment, the disc 403 is moved away from the water inlet 402. As the disc 403 moves, the sampling tank 401 is negatively attracted to the liquid, and the liquid is quickly moved into the sampling tank 401, thereby achieving liquid sampling and processing inside the river channel. The splicing groove 406 can be used in conjunction with the adjustment component 5 to increase connectivity.

[0029] Specifically, such as Figure 3 As shown, the adjustment assembly 5 includes a circular hole 501, an adjustment rod 502 is slidably connected inside the circular hole 501, an adjustment plate 503 is fixedly connected to the rear side of the adjustment rod 502, and the bottom of the adjustment plate 503 contacts the top of the connecting rod 404.

[0030] Specifically, such as Figure 3 As shown, a splicing block 504 is fixedly connected to the bottom of the adjusting plate 503, and the side of the splicing block 504 away from the adjusting plate 503 is engaged with the inner wall of the splicing groove 406.

[0031] Specifically, such as Figure 3 As shown, a round block 505 is fixedly connected to the top of the adjusting rod 502, and a pressing block 506 is fixedly connected to the top of the round block 505.

[0032] In this embodiment: by setting a circular hole 501, the adjusting rod 502 is movably connected to the frame 1. By setting the adjusting rod 502, adjusting plate 503 and splicing block 504, the splicing block 504 contacts the inner wall of the splicing groove 406, increasing the connectivity between the splicing block 504 and the connecting rod 404, so that the adjusting plate 503 contacts the top of the connecting rod 404. Then, as the user manually adjusts the adjusting rod 502 in the inner wall of the circular hole 501, the height of the connecting rod 404 is adjusted. Several adjusting plates 503 that are horizontal with several locking grooves 2 are fixedly connected to the rear side of the adjusting rod 502.

[0033] Specifically, such as Figure 4As shown, the top and bottom of the inner wall of the snap-fit ​​groove 2 are provided with sliding grooves 6, and the top and bottom of the snap-fit ​​block 3 are fixedly connected with sliders 7 that cooperate with the sliding grooves 6.

[0034] Specifically, such as Figure 5 As shown, a protective sleeve 8 is fixedly connected inside the sampling container 401. The protective sleeve 8 is made of stainless steel.

[0035] In this embodiment: by setting the slide groove 6 and the slider 7, the slider 7 contacts the inner wall of the slide groove 6 to prevent the locking block 3 from loosening with the locking groove 2, and by setting the protective sleeve 8, the problem of liquid corroding the inner wall of the sampling tank 401 is reduced.

[0036] Specifically, such as Figure 1 As shown, a soft pad 9 is fixedly connected to the bottom of the frame 1. The soft pad 9 is made of silicone.

[0037] Specifically, such as Figure 2 As shown, a sealing block 10 is snapped into the inside of the water inlet 402, and a pull-out block 11 is fixedly connected to the top of the sealing block 10. The sealing block 10 is made of silicone.

[0038] In this embodiment: by setting the soft pad 9, it is convenient for the user to carry or operate the frame 1. By setting the sealing block 10 and the pull block 11, the sealing block 10 seals the water inlet 402, and the pull block 11 removes the sealing block 10 from the inner wall of the water inlet 402. When using this structure, the sealing block 10 needs to be removed from the inner wall of the water inlet 402 in advance. After sampling, the sealing block 10 is brought into contact with the inner wall of the water inlet 402 to seal the sampling container 401 for subsequent carrying.

[0039] Working principle: First, according to the sampling depth requirements, the snap-fit ​​block 3 with extraction component 4 is snapped into the snap-fit ​​groove 2 at different heights on the front side of the frame 1. The slider 7 on the snap-fit ​​block 3 cooperates with the sliding groove 6 on the inner wall of the snap-fit ​​groove 2 to ensure a stable connection. Then, the sampling tank 401 is manually installed on the installation sleeve 405. At this time, the sealing block 10 of the water inlet 402 has been removed in advance by the pull block 11. The installed frame 1 is placed into the target river channel. The pressing block 506 on the top of the adjusting rod 502 is pressed by hand, which causes the adjusting rod 502 to slide in the round hole 501. The rear side of the adjusting rod 502 is connected to The adjusting plate 503 moves accordingly, and the splicing block 504 at the bottom of the adjusting plate 503 is tightly engaged with the splicing groove 406 at the top of the connecting rod 404, thereby adjusting the height of the connecting rod 404 so that the disc 403 rises in the sampling tank 401 away from the water inlet 402. As the disc 403 moves upward, a negative pressure is formed in the sampling tank 401. Under the action of pressure difference, the river water flows quickly into the sampling tank 401 through the water inlet 402. After sampling is completed, the height of the frame 1 is adjusted to move away from the river. Then, the sealing block 10 is inserted into the water inlet 402 to seal the sampling tank 401 for easy carrying later.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
