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.

[0023] Please see Figure 1-5This utility model provides a technical solution: an environmental testing water quality sampling device, comprising: a sleeve 1, a threaded groove 101 extending downward from the top of the sleeve 1, a limiting groove 102 extending downward through the center of the bottom of the threaded groove 101, limiting grooves 103 on both sides of the limiting groove 102, a connecting thread 104 at the bottom of the surface of the sleeve 1, and handles 2 fixedly connected to both sides of the surface of the sleeve 1 near the top, an adjusting sleeve structure 3 inside the threaded groove 101, an adjusting rod structure 4 inside the adjusting sleeve structure 3, a connecting threaded sleeve 5 threadedly fitted onto the surface of the connecting thread 104, and a water intake structure 6 at the bottom of the connecting threaded sleeve 5.

[0024] Specifically: the threaded groove 101 and the mating thread 305 are mated to adjust the rotation of the adjusting sleeve 301; the limiting through groove 102 is used to limit the movement of the adjusting rod 401; the limiting slide groove 103 is used in conjunction with the limiting slider 405 to limit the movement of the sealed bearing 404; the handle 2 is used to fix the auxiliary sleeve 1; the adjusting sleeve structure 3 is used to adjust the rotation of the adjusting rod structure 4; and the adjusting rod structure 4 is used to connect with the internal components of the water intake structure 6.

[0025] In one embodiment, the adjusting sleeve structure 3 includes an adjusting sleeve 301. The top of the adjusting sleeve 301 extends downward and is provided with a hexagonal limiting groove 302. A limiting through groove 303 is provided downward through the center of the bottom of the hexagonal limiting groove 302. Handles 304 are fixedly connected to the top of both sides of the surface of the adjusting sleeve 301. A mating thread 305 is provided on the lower part of the surface of the adjusting sleeve 301. The mating thread 305 is threaded into the inside of the threaded groove 101.

[0026] Specifically, such as Figure 2 , 3 As shown in Figure 5: the hexagonal limiting groove 302 is used to cooperate with the hexagonal limiting block 402 to rotate and position the adjusting rod 401; the adjusting sleeve 301 is used to rotate and adjust the adjusting rod structure 4; the second limiting through groove 303 is used to limit the movement of the adjusting rod 401; the second handle 304 is used to assist the adjusting sleeve 301 in rotating; and the depth of the hexagonal limiting groove 302 matches the hexagonal limiting block 402.

[0027] In one embodiment, the adjusting rod structure 4 includes an adjusting rod 401, which is movably fitted and embedded inside the limiting groove 303. The top end of the surface of the adjusting rod 401 is movably fitted inside the hexagonal limiting groove 302, the middle part of the surface of the adjusting rod 401 is movably fitted inside the threaded groove 101, and the bottom end of the surface of the adjusting rod 401 is movably fitted and embedded inside the limiting groove 102.

[0028] Specifically, such as Figure 2 , 3 As shown: Adjusting rod 401 is used to connect and dock with adjusting rod 403.

[0029] In one embodiment, a hexagonal limiting block 402 is fixedly sleeved on the top of the surface of the adjusting rod 401. The hexagonal limiting block 402 is movably fitted and embedded inside the hexagonal limiting groove 302. A connecting adjusting rod 403 is fixedly connected to the bottom of the adjusting rod 401. A sealing bearing 404 is sleeved on the surface of the connecting adjusting rod 403. Limiting sliders 405 are fixedly connected to both sides of the surface of the sealing bearing 404. The two limiting sliders 405 are movably fitted and embedded inside the two limiting grooves 103 respectively. A hexagonal docking block 406 is fixedly connected to the bottom of the connecting adjusting rod 403. The hexagonal docking block 406 is movably embedded inside the limiting through groove 102.

[0030] Specifically, such as Figure 2 , 3 As shown in Figure 5: The hexagonal limiting block 402 cooperates with the hexagonal limiting groove 302 to make the adjusting rod 401 and the adjusting sleeve 301 dock and fix it, so that the adjusting rod 401 rotates synchronously with the adjusting sleeve 301. The angle of the hexagonal limiting block 402 and the hexagonal docking block 406 corresponds. When the limiting slider 405 moves to the top of the inner cavity of the limiting slide groove 103 and the threaded movable plate 606 rotates to the top of the threaded groove 602, the angle of the hexagonal docking block 406 and the hexagonal docking groove 610 matches and corresponds.

[0031] In one embodiment, the water intake structure 6 includes a water intake bucket 601, which is fixedly and continuously sleeved on the bottom of the surface of the connecting threaded sleeve 5, and the inside of the water intake bucket 601 is provided with a threaded groove 602.

[0032] Specifically, such as Figure 1 , 2 As shown in Figure 4: the water bucket 601 is used for temporary storage of river water samples, and the threaded groove 602 is used to mate with the threaded movable plate 606 and the annular baffle 607.

[0033] In one embodiment, a drain pipe 603 is fixedly embedded in the top of one side of the water tank 601, and a gas-liquid one-way valve 604 is fixedly embedded inside the drain pipe 603. A water inlet pipe 605 is fixedly embedded in the bottom of one side of the water tank 601.

[0034] Specifically, such as Figure 1 , 2As shown in Figures 4 and 5: the drain pipe 603 is used to drain the sampled water inside the water collection bucket 601; the gas-liquid one-way valve 604 is used to prevent river water from entering the water collection bucket 601 through the drain pipe 603 when sampling the water inside the river; and the inlet pipe 605 is used to introduce the water inside the river into the water collection bucket 601.

[0035] In one embodiment, a threaded movable plate 606 is threadedly embedded on the inner side of the threaded groove 602. An annular baffle 607 is fixedly connected to the bottom of the threaded movable plate 606. The annular baffle 607 is threadedly embedded on the inner side of the threaded groove 602. A connecting rod 608 is fixedly connected at the center of the top of the threaded movable plate 606. The connecting rod 608 is movably embedded inside the connecting threaded sleeve 5. A connecting block 609 is fixedly connected to the top of the connecting rod 608. A hexagonal connecting groove 610 is opened at the center of the top of the connecting block 609. The water bucket 601 is movably fitted onto the surface of the hexagonal connecting block 406.

[0036] Specifically, such as Figure 1 , 2 As shown in Figures 4 and 5: The annular baffle 607 is used to increase the tightness of the connection between the threaded movable plate 606 and the threaded groove 2 602. The hexagonal docking groove 610 is used to dock the hexagonal docking block 406, completing the docking of the docking rod 608 and the connecting adjustment rod 403. In the initial state, the threaded movable plate 606 is located at the top of the inner side of the threaded groove 2 602. The bottom of the docking thread 1 305 rotates and engages with the top of the inner side of the threaded groove 101. At this time, the distance between the limiting slider 405 and the bottom of the inner cavity of the limiting slide groove 103 is equal to the depth of the hexagonal limiting block 402 embedded in the hexagonal limiting groove 302 and the distance of the hexagonal docking block 406 embedded in the hexagonal docking groove 610. The thread direction of the connecting thread 104 is opposite to the thread direction of the threaded groove 2 602, so as to prevent the connecting threaded sleeve 5 from disengaging from the surface of the connecting thread 104 when the threaded movable plate 606 is rotated.

[0037] Working principle: This water sampling device can be used by hand while standing on the shore or by taking a boat to the water surface to collect samples, depending on the sampling location.

[0038] When using this water quality sampling device for river environmental monitoring, take out a water sampling bucket 601 from the external storage box, rotate and remove the threaded plug of the threaded sleeve 5 connected to the top of the water sampling bucket 601, then hold the surface of the sleeve 1 and screw the connecting thread 104 completely into the interior of the connecting threaded sleeve 5. Because the angle of the hexagonal mating block 406 does not correspond to the hexagonal mating groove 610 when rotating the sleeve 1, pull the top of the adjusting rod 401 upward to disengage the hexagonal limiting block 402 from the interior of the hexagonal limiting groove 302, and then continue to rotate the sleeve 1. When the thread 104 is fully screwed into the threaded sleeve 5, the limiting slider 405 moves to the top of the inner cavity of the limiting groove 103. The top of the adjusting rod 401 is rotated to align the hexagonal limiting block 402 with the hexagonal limiting groove 302 at the same angle. At the same time, the hexagonal mating block 406 is aligned with the hexagonal mating groove 610 at the same angle. The hexagonal limiting block 402 is pressed down into the hexagonal limiting groove 302, and the hexagonal mating block 406 is pressed into the hexagonal mating groove 610. At the same time, the limiting slider 405 moves downward along the inside of the limiting groove 103 to complete the mating installation.

[0039] This setup results in a simple structure and allows for quick docking and installation.

[0040] Then, holding the surface of the sleeve 1, insert the water bucket 601 into the river channel. Hold the handle 1 2 at the top of the sleeve 1 with one hand and the handle 2 304 at the top of the adjusting sleeve 301 with the other hand, and limit the top of the adjusting rod 401. Rotate the adjusting sleeve 301. At this time, because the hexagonal limiting block 402 and the hexagonal limiting groove 302 are engaged and connected, the adjusting rod 401 moves downward with the rotation of the adjusting sleeve 301. At the same time, the limiting slider 405 moves downward along the inside of the limiting groove 103. At this time, because the hexagonal connecting block 406 is engaged and fixed with 10, the connecting adjusting rod 403 drives the threaded movable plate 606 to rotate synchronously through the connecting rod 608. At this time, because the threaded movable plate 606, the annular baffle 607 are engaged with the core of the threaded groove 2 602, the threaded movable plate 606 and the annular baffle 607 move downward along the inside of the threaded groove 2 602.

[0041] When the connecting thread 305 is fully screwed into the threaded groove 101, the threaded movable plate 606 rotates to the bottom of the inner side of the threaded groove 602. At this time, the top surface of the threaded movable plate 606 corresponds to the opening at one end of the bottom of the inner side of the water inlet pipe 605. At this time, the river water inside the channel enters the water intake bucket 601 through the water inlet pipe 605. After a period of time, when the river water fills the bottom of the inner cavity of the water intake bucket 601, the connecting threaded sleeve 5, and the limiting through groove 102, the adjusting sleeve 301 is rotated in the opposite direction. At this time, the threaded movable plate 606 and the annular baffle 607 move upwards towards the inner cavity of the water intake bucket 601. The river water inside the water collection bucket 601 is squeezed, and the excess river water is squeezed to open the gas-liquid one-way valve 604 and discharged from the inside of the drain pipe 603. After rotating the adjusting sleeve 301 a certain number of turns, the surface of the annular baffle 607 is rotated to seal the opening at the connection between the water inlet pipe 605 and the water collection bucket 601. Finally, the water collection bucket 601 is pulled out upward by holding the sleeve 1, and the water collection bucket 601 is removed by rotating the connecting threaded sleeve 5. Then, an external threaded plug is installed on the top of the connecting threaded sleeve 5. The above operation is repeated to sample the river water at different locations inside the river area and store it inside the water collection bucket 601.

[0042] With this setup, the structure is easy to operate and does not rely on an external power supply.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
