Description

Technical Field

[0001] This utility model relates to the field of sampler technology, specifically a sampler for detecting water resources for ecological and environmental protection. Background Technology

[0002] Water, one of the most precious natural resources on Earth, is the foundation for human survival and development, and is hailed as the source of life. From daily life to industrial and agricultural production, all aspects of human society rely on water. Among these, the quality and safety of drinking water directly impact the health and quality of life of the people. With rapid socio-economic development and continuous industrialization, human demand for water resources is constantly increasing, and the level of development and utilization is also rising. However, the total amount of freshwater resources on Earth is finite and its distribution is extremely uneven, making water resource protection particularly important and urgent. In recent years, with the deepening of ecological civilization construction and the widespread enhancement of environmental awareness, the requirements for water resource monitoring have become increasingly stringent. To comprehensively understand water quality, promptly identify problems, and take effective measures, it is essential to conduct scientific and standardized sampling and testing of various water sources. Currently, water samplers have become an indispensable tool in water resource monitoring, providing reliable first-hand data for subsequent laboratory analysis by collecting water samples on-site at water sources.

[0003] Some existing water resource testing samplers lack necessary filtration devices. When sampling in rivers with high sediment content or turbid waters, sediment particles in the water can directly enter the sampler with the water flow. During the subsequent piston movement, these hard sediment particles continuously rub against the piston sealing surface, increasing operating resistance and causing rapid wear of the piston seals. Over time, this wear significantly reduces the sampler's sealing performance, shortens the lifespan of critical components, and consequently affects the accuracy of water quality testing results, increasing equipment maintenance and replacement costs. Therefore, this invention provides an ecological environmental protection water resource testing sampler to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a water resource testing and sampling device for ecological environmental protection, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0023] 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 scope of protection of the present utility model.

[0024] Please see Figures 1 to 7 In this embodiment of the utility model, an ecological environment protection water resource detection sampler includes a sampler body 1. A partition 2 is fixedly installed inside the sampler body 1, dividing the sampler body 1 into two spaces. The upper part of the partition 2 is a motor cavity, and the lower part is a sampling cavity. A storage battery 3 is fixedly installed on the top surface of the partition 2, providing power for the operation of a drive motor 5. A piston 4 is slidably installed inside the sampler body 1. A drive assembly for providing power for the movement of the piston 4 is provided on the top surface of the partition 2. A filter box 13 is fixedly installed on the surface of the sampler body 1. Two sets of filter boxes 13 are symmetrically arranged on the left and right sides of the sampler body 1. A sampling tube 14 is fixedly installed on the bottom surface of sampler body 1. A first baffle 15 for sealing the sampling tube 14 is rotatably installed inside the filter box 13. A cleaning component for removing sediment from the inside of the filter box 13 is provided inside the filter box 13. A drain pipe 26 is fixedly installed on the bottom surface of sampler body 1. A drain component for unidirectional discharge of the sample inside sampler body 1 is provided at the bottom of sampler body 1. Through holes 32 are opened on the surface of sampler body 1. Two sets of through holes 32 are provided. A filter plate 33 is fixedly installed inside the through holes 32. Through the setting of filter plate 33, the sampled water resources can be filtered to prevent sediment from entering the interior of sampler body 1, thereby avoiding the wear of the piston 4 inside sampler body 1 by sediment.

[0025] like Figure 2 and Figure 3As shown, the drive assembly includes a drive motor 5 fixedly mounted on the top surface of the partition 2. A rotating shaft 6 is fixedly mounted on the output end of the drive motor 5. A first gear 7 is fixedly mounted on the surface of the rotating shaft 6. An internally threaded cylinder 10 is slidably mounted inside the partition 2. The bottom end of the internally threaded cylinder 10 is fixedly connected to the piston 4. To ensure that the internally threaded cylinder 10 can move stably up and down within the sampler body 1, a slider 11 is fixedly mounted on the surface of the internally threaded cylinder 10. A sliding groove 12 is provided inside the partition 2. The slider 11 is slidably mounted inside the sliding groove 12. A threaded rod 8 is threaded inside the internally threaded cylinder 10. A second gear 9 is fixedly mounted on the surface of the threaded rod 8. The second gear 9 meshes with the first gear 7. By rotating the drive motor 5 in both directions, the piston 4 can be driven to move up and down, adjusting the air pressure inside the sampler body 1 to sample water resources.

[0026] like Figure 3 and Figure 5 As shown, rotating columns 16 are fixedly installed on both sides of the first baffle 15. The rotating columns 16 are rotatably connected to the filter box 13. A torsion spring 17 is fixedly connected between the first baffle 15 and the filter box 13. The torsion spring 17 is sleeved on the surface of the rotating column 16. A first sealing ring 18 is fixedly installed on the bottom surface of the first baffle 15. By setting the first baffle 15, the sampling tube 14 can be sealed, and water from other depths can be prevented from entering the sampler body 1 after sampling.

[0027] like Figure 6 As shown, the cleaning assembly includes a cleaning plate 19 movably installed inside the filter box 13. Two sets of connecting rods 20 are fixedly installed on the surface of the cleaning plate 19. A sealing plate 21 is fixedly installed at the end of the connecting rod 20 away from the cleaning plate 19. A second sealing ring 22 is fixedly installed on the side of the sealing plate 21 near the connecting rod 20. A handle 23 is fixedly installed on the side of the sealing plate 21 away from the connecting rod 20. Four mounting blocks 24 are fixedly installed on the side of the sealing plate 21. Each mounting block 24 has a threaded fixing bolt 25. The surface of the sampler body 1 has threaded grooves that can cooperate with the fixing bolts 25. The sealing plate 21 is fixed to the sampler body 1 by the fixing bolts 25. After the sample water inside the sampler body 1 is discharged, the sealing plate 21 can be disassembled. Then, the handle 23 is pulled to move the cleaning plate 19, thereby pushing the internal sediment out of the filter box 13 for collection, facilitating subsequent detection of pollutants adsorbed on the sediment.

[0028] like Figure 7As shown, the drainage assembly includes an outlet pipe 27 fixedly installed at the bottom of the sampler body 1. An installation frame 28 is fixedly installed inside the outlet pipe 27. A telescopic rod 29 is fixedly installed on the bottom surface of the installation frame 28. A second baffle 31 is fixedly installed at the bottom end of the telescopic rod 29. A compression spring 30 is fixedly connected between the installation frame 28 and the second baffle 31. The compression spring 30 is sleeved on the surface of the telescopic rod 29. During sampling, under the action of the compression spring 30, the second baffle 31 can be tightly attached to the bottom surface of the outlet pipe 27 to prevent mud and sand from entering the interior of the sampler body 1. When the sample water inside the sampler body 1 is discharged, the piston 4 moves down, the pressure inside the sampler body 1 increases, overcoming the elastic force of the compression spring 30, the second baffle 31 moves down, and the sample water inside the sampler body 1 can be discharged.

[0029] A movable frame 34 is movably mounted on the surface of the sampler body 1. A traction rope 35 is fixedly mounted on the top surface of the movable frame 34. The traction rope 35 facilitates the adjustment of the depth of the sampler body 1 in the water source, thereby facilitating the sampling and testing of water bodies at different depths.

[0030] The working principle of this utility model is as follows: When conducting water resource testing for ecological environmental protection, the sampler body 1 is placed into the water resource to be tested. The depth of the sampler body 1 in the water can be adjusted by the traction rope 35, facilitating sampling and testing of water resources at different depths. After adjusting the depth of the sampler body 1 in the water resource, the drive motor 5 is started. The output end of the drive motor 5 rotates, driving the rotating shaft 6 to rotate, causing the first gear 7 to rotate. The first gear 7 meshes with the second gear 9, causing the second gear 9 to rotate, which in turn drives the threaded rod 8 to rotate. The threaded rod 8 is threadedly connected to the internal threaded cylinder 10. As the threaded rod 8 rotates, the internal threaded cylinder 10 moves upward, thereby driving the piston 4 within the sampler body. As the sampler moves upward, the air pressure inside the sampler body 1 decreases. The external atmospheric pressure forces water from the sampling tube 14 (high-pressure zone) into the sampler body 1 (low-pressure zone). The water flow then pushes the first baffle 15 to rotate around the rotating column 16, causing the torsion spring 17 to deform and release the first baffle 15 from the sampling tube 14, allowing water to flow into the filter box 13. Simultaneously, the water entering the filter box 13 enters the sampler body 1 through the through hole 32. The filter plate 33 blocks sediment in the water, preventing it from entering the sampler body 1 and thus avoiding wear on the piston 4, extending its service life. When the water flows into the sampler body 1 and the filter box 13, the first baffle 15 rotates around the rotating column 16, causing the torsion spring 17 to deform and release the seal of the first baffle 15 from the sampling tube 14, allowing water to flow into the filter box 13. Once the pressure inside and outside the sampler body 1 is rebalanced, the torsion spring 17 begins to rebound, causing the first baffle 15 to rotate and reset. The first baffle 15 then re-closes the sampling tube 14, thus storing the sampled water inside the sampler body 1. Simultaneously, a first sealing ring 18 is provided on the bottom surface of the first baffle 15. This sealing ring 18 increases the sealing performance of the first baffle 15 to the sampling tube 14, preventing upper-layer water from entering the sampler body 1 when it is removed from the water, and avoiding interference from water samples at different depths. After sampling is complete, when the sample needs to be discharged, the drive motor 5 is restarted. The output of the drive motor 5 rotates in the reverse direction, driving the rotating shaft 6 to rotate, thus... The rotation of the first gear 7 and the second gear 9 causes the threaded rod 8 to rotate, which in turn causes the internal threaded cylinder 10 to move downwards. This, in turn, causes the piston 4 to move downwards within the sampler body 1, increasing the air pressure inside the sampler body 1. As the internal air pressure increases, it pushes the second baffle 31 downwards, causing the compression spring 30 to deform and release the second baffle 31 from the liquid outlet pipe 27. This allows the sampled water in the sampler body 1 to enter the liquid outlet pipe 27 and be discharged through the drain pipe 26. After the water sample in the sampler body 1 is discharged, the sealing plate 21 can be opened, and the handle 23 can be pulled outwards to move the cleaning plate 19. As the cleaning plate 19 moves, the sediment in the filter box 13 can be pushed out, facilitating subsequent testing of the collected water sample.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
