The sealing ring is installed at the upper opening of the barrel body. A handle is arranged on the circular outer wall. A sundry filtering device is arranged on the outer wall of the upper end of the sealing ring. A protective sinking bottom device is arranged on the circular outer wall of the barrel body and below the handle, and a sundry filtering device is added at the upper end of the barrel body.

[0004] However, it is found in the implementation of the related technology that the above technical solution has the following problems: the above device is not convenient for layered sampling and detection of polluted water sources during use. Since there are certain deviations in the detection results of water sources at different depths, it is necessary to sample and detect water sources at different depths simultaneously during the sampling process to accurately understand the true situation of its water quality. Therefore, further improvement is needed. Content of the Utility Model

[0025] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention. Embodiment 1

[0026] As Figures 1 to 3 shown, this embodiment proposes a device for stratified sampling of water resource pollution, including a sampler 1. A buoyancy plate 2 is fixedly connected to the top of the sampler 1. Four water inlet tanks 3 are opened on one side of the outside of the sampler 1. Four partition boards 4 are fixedly connected inside the sampler 1. Four filter boards 5 are also fixedly connected inside the sampler 1. An isolation board 6 is fixedly connected inside the sampler 1. Four round holes 7 are opened inside the isolation board 6. A cylinder 8 is provided on the top of the sampler 1. A support plate 9 is fixedly connected to the bottom of the cylinder 8. A piston rod 10 is slidably connected inside the cylinder 8. One end of the piston rod 10 is fixedly connected to a rack 11. A gear 12 is provided on the top of the sampler 1. The rack 11 and the gear 12 are meshed with each other. A butterfly rod 13 is fixedly connected to the bottom of the gear 12. Four butterfly plates 14 are fixedly connected to the outside of the butterfly rod 13. Four water outlet tanks 15 are opened on the other side of the outside of the sampler 1.

[0027] In this embodiment, one side of the outside of the partition board 4 is fixedly connected to one side of the outside of the isolation board 6, and one side of the outside of the filter board 5 is fixedly connected to one side of the outside of the isolation board 6, which can facilitate the isolation of water samples in different layers in different partition spaces.

[0028] In this embodiment, the support plate 9 is fixedly connected between the inner walls of the buoyancy plate 2, and the bottom of the rack 11 is slidably connected to the top of the sampler 1, which can facilitate the movement of the piston rod 10 to drive the movement of the rack 11 at the same time.

[0029] In this embodiment, the butterfly plate 14 is in contact with the round hole 7, the butterfly rod 13 extends into the inside of the isolation board 6 and is rotatably connected thereto, and the butterfly rod 13 is rotatably connected to the sampler 1, which can facilitate the rotation of the gear 12 to drive the rotation of the butterfly rod 13 at the same time.

[0030] In use, the staff first place the sampler 1 in the contaminated water area. Subsequently, water at different depths is respectively poured into the interior of the sampler 1 from the four water inlet grooves 3 and the filter plate 5. At this time, the staff control the air cylinder 8 to drive the piston rod 10 to move. When the piston rod 10 moves, it will drive the rack 11 to move. When the rack 11 moves, it will drive the gear 12 to rotate. When the gear 12 rotates, it will drive the butterfly rod 13 to rotate. When the butterfly rod 13 rotates, it will drive the four butterfly plates 14 to rotate. When the four butterfly plates 14 rotate, water at different depths will flow into the four spaces isolated by the isolation plate 6 and the partition plate 4 from the opening between the round hole 7 and the butterfly plate 14. When these four spaces are filled, the staff control the air cylinder 8 to drive the piston rod 10 to reset. When the piston rod 10 resets, it will drive the rack 11 to reset. When the rack 11 resets, it will drive the gear 12 to rotate in the reverse direction. When the gear 12 rotates in the reverse direction, it will drive the butterfly rod 13 to rotate in the reverse direction. When the butterfly rod 13 rotates in the reverse direction, it will drive the butterfly plate 14 to rotate in the reverse direction. At this time, the round hole 7 is in contact with the butterfly plate 14 to isolate the water source. When the sampling is completed, when the staff take out the sampler 1, the excess water inside the sampler 1 will flow out from the filter plate 5 and the water inlet groove 3 respectively. Through the above device, it is convenient for the staff to conduct stratified sampling of the contaminated water area, and the water after sampling can enter different separated spaces, thereby preventing the mixing of water samples, improving the sampling efficiency, and also being able to avoid inaccurate understanding of the water pollution situation due to the mixing of water samples. Embodiment 2

[0031] As Figures 4 to 5 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that four water outlet grooves 15 are fixedly connected with four water pipes 16 on the outside. Two connection grooves 17 are opened inside the four water pipes 16. One end of each of the four water pipes 16 is provided with a sealing cover 18, and the sealing cover 18 is adapted to the water pipe 16, which can facilitate the sealing of the water source sampled in different spaces by the sealing cover 18.

[0032] In this embodiment, one side of the outside of the sealing cover 18 is fixedly connected with a fixing plate 19, the top of the fixing plate 19 is fixedly connected with a spring 20, and two rotating rods 21 are also fixedly connected to one side of the outside of the sealing cover 18.

[0033] In this embodiment, a connecting plate 22 is movably connected between the middle positions of the two rotating rods 21 through a rotating shaft. A clamping plate 23 is rotatably connected to the outside of the connecting plate 22, and the clamping plate 23 is fixedly connected to the spring 20, which can facilitate the compression of the spring 20 when the clamping plate 23 is stressed.

[0034] In this embodiment, a buckle 24 is fixedly connected to one side of the clamping plate 23, and the buckle 24 is in contact with the connection groove 17, which can facilitate the fixing of the sealing cover 18 on the outside of the water pipe 16.

[0035] After sampling is completed, the staff first place the test container bottle at the lower opening of the water pipe 16. Subsequently, the buckle 24 is pressed into the inside of the connection groove 17. When the buckle 24 is stressed, it will drive the clamping plate 23 to be stressed. When the clamping plate 23 is stressed, it will drive the spring 20 to compress. While the spring 20 is compressing, the clamping plate 23 will rotate into the inside of the connection groove 17. Subsequently, the buckle 24 will also enter the inside of the connection groove 17. At this time, the staff can remove the sealing cover 18 by pulling it. When the sealing cover 18 is removed, the sampled water inside it will flow out through the water pipe 16. At this time, the staff can test the water sources at different depths one by one according to needs.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
