Description

Technical Field

[0001] The present invention relates to the technical field of water quality sampling, and more specifically, it relates to a sampling mechanism for water quality detection in environmental engineering. Background Art

[0002] In the field of modern environmental engineering, water quality monitoring and sampling is a crucial task, which is of great significance for evaluating the health status of water bodies, formulating environmental protection strategies, and conducting scientific research. However, the currently widely used water quality sampling devices have some limitations in practical applications. The most prominent problem is that these devices often cannot sample at specific water depths. This defect seriously affects the accuracy and effectiveness of sampling. Since there may be differences in physical, chemical, and biological characteristics at different depths of the water body, the inability to sample at precise depths means that we may miss key water quality information, resulting in deviations and incompleteness in monitoring results.

[0003] This limitation has various negative impacts on the effect of environmental engineering detection. Firstly, it reduces the reliability of water quality data, making it difficult for researchers and environmental protection workers to accurately evaluate the pollution status or ecological characteristics of specific water layers. Secondly, when conducting vertical profile analysis, due to the lack of precise depth sampling ability, we cannot comprehensively understand the stratification structure of the water body and the interactions between different layers, thus reducing the accuracy of detection.

[0021] Please refer to Figures 1 to 5, An environmental engineering water quality detection sampling mechanism, including a water storage pipe 1, a sampling mechanism is arranged on the water storage pipe 1. The sampling mechanism includes a connection mechanism, a water inlet pipe 2, a scale disk 3, a sliding rod 4, a top disk 5, a bottom disk 6, a bottom ring 7, a top ring 8, a transmission rod 9 and an adjustment mechanism. There are multiple water storage pipes 1, and a connection mechanism is installed between every two water storage pipes 1. A water inlet pipe 2 is installed on each water storage pipe 1. A scale disk 3 is coaxially installed on the water inlet pipe 2. A sliding rod 4 is slidably connected to the scale disk 3. A plurality of communication grooves 10 are equidistantly opened on the side wall of the sliding rod 4. The upper and lower ends of the sliding rod 4 are coaxially installed with a top disk 5 and a bottom disk 6 respectively. An indicating groove 11 is opened on the top disk 5. A top ring 8 is installed on the lower end surface of the top disk 5. A bottom ring 7 is installed on the upper end surface of the bottom disk 6. Bidirectional grooves 12 are opened at both ends of the scale disk 3. The transmission rod 9 is installed on the sliding rod 4. The adjustment mechanism is installed in the water inlet pipe 2. A synchronous disk 13 is provided on the transmission rod 9. The synchronous disk 13 is slidably connected in the water inlet pipe 2. A spring 14 is sleeved on the transmission rod 9, and the spring 14 is connected to the bottom disk 6.

[0022] Working principle: When sampling at different water depths, first determine how many segments to sample according to the water depth where sampling is needed, and then connect multiple water storage pipes 1 through the connection mechanism. According to the intermediate rods 27 of different lengths, the positions between multiple water storage pipes 1 can be adjusted to meet the corresponding segmentation requirements. Then, adjust the depth of water intake required for each water inlet pipe 2 according to the corresponding water depth, so as to meet the corresponding water intake requirements.

[0023] When sampling, water will flow into the water storage pipe 1 through the water inlet pipe 2, and then flow into the lower end of the water storage pipe 1 through a plurality of through holes 22, continuously storing water. When the stored water submerges the cone head 23, due to the corresponding buoyancy of the cone head 23 and different buoyancies generated at different positions of the cone head 23, the buoyancy gradually increases as the water level rises. Then when the water contacts the floating disk 21, a relatively large buoyancy will be provided, and then the buoyancy is transmitted to the transmission rod 9 through the intermediate spring 20. At this time, the buoyancy of the spring 14 and the floating disk 21 will be greater than the water pressure. Therefore, the bottom ring 7 and the bidirectional groove 12 are in a sealed state again, ensuring that the sample is pure and not contaminated. When multiple water storage pipes 1 need to be taken out after sampling respectively, since the water pressure decreases after moving upward, the water pressure will be even less than the buoyancy and the elastic force of the spring 14, further ensuring the sealing of the sampling.

[0024] When adjusting, since corresponding adjustments need to be made for different water depths, there are many scales on the scale disk 3 and an indicating groove 11 on the top disk 5. Therefore, the corresponding water depth range can be determined according to the indication between the indicating groove 11 and the scale line. By performing the above operations on multiple water inlet pipes 2 respectively, the adjustment process can be completed.

[0025] To meet the requirement of sampling at different water depths, an adjustment mechanism is added. Please refer to Figures 3 to 4 , the adjustment mechanism includes a threaded sleeve 15 and a transmission sleeve 16. The threaded sleeve 15 is threadedly connected to the inner wall of the water inlet pipe 2. The transmission sleeve 16 is installed on the threaded sleeve 15. The transmission rod 9 is slidably connected inside the transmission sleeve 16. A spring 14 is connected to the threaded sleeve 15. A guide rod 17 is provided on the transmission rod 9. A positioning disk 18 is slidably provided inside the water inlet pipe 2. A guide sleeve 19 is provided on the positioning disk 18. The guide rod 17 is slidably connected inside the guide sleeve 19. An intermediate spring 20 is sleeved on the guide rod 17. One end of the intermediate spring 20 is connected to the transmission rod 9, and the other end of the intermediate spring 20 is connected to the guide sleeve 19. A floating disk 21 is provided on the guide sleeve 19. The floating disk 21 is slidably connected inside the water storage pipe 1. A plurality of through holes 22 are equidistantly opened on the floating disk 21. A tapered head 23 is provided on the lower end surface of the floating disk 21. The tapered head 23 and the guide sleeve 19 are coaxially arranged.

[0026] Working principle: During the water quality sampling process in environmental engineering, precisely adjusting the sampling requirements of different inlet pipes 2 is a crucial step to ensure data accuracy. This complex adjustment process involves the coordinated operation of multiple components. First, the operator drives the top disk 5 to rotate. Since the transmission rod 9 is installed on the sliding rod 4, the rotation of the top disk 5 will directly drive the transmission rod 9 to rotate synchronously. The transmission sleeve 16, as a key component connecting the transmission rod 9 and the threaded sleeve 15, is slidably connected to the transmission rod 9 and rotates with the rotation of the transmission rod 9. At the same time, the threaded sleeve 15 also rotates with the rotation of the transmission rod 9. The threaded connection design between the threaded sleeve 15 and the inlet pipe 2 enables the rotation of the threaded sleeve 15 to precisely change the distance between it and the bottom disk 6. This change in distance directly affects the core function of the device, namely the pressure adjustment of the spring 14. The spring 14 is arranged between the threaded sleeve 15 and the bottom disk 6. As the distance between the two changes, the compression degree of the spring 14 also changes, thereby changing the elastic force it provides. The purpose of this design is that it allows the operator to precisely adjust the sensitivity of the device to water pressure through a simple rotation action. When the inlet pipe 2 reaches the preset water depth, the balance relationship between the water pressure and the elastic force of the spring 14 begins to take effect. If the water pressure is greater than the elastic force of the spring 14, it will push the top disk 5 to slide downward, and then the connection between the bottom ring 7 and the double groove 12 is released. This unlocking process is crucial for ensuring the accuracy of sampling because it allows the water sample to enter the device only at a specific depth. Once the connection between the bottom disk 6 and the scale disk 3 is released, the water at the corresponding depth can flow into the inlet pipe 2 through the multiple communication grooves 10 on the side wall of the sliding rod 4. The design of these communication grooves 10 not only ensures the smooth entry of the water sample but also helps to maintain the continuity and stability of the sampling process. The water sample then flows into the storage pipe 1 through the inlet pipe 2 to complete the sampling process. However, when the inlet pipe 2 exceeds the preset depth, the increased water pressure will continue to push the top disk 5 downward until the top ring 8 abuts against the double groove 12. This design achieves the automatic closure of over-deep sampling: a new sealing state is formed between the top disk 5 and the scale disk 3, preventing the water sample at non-target depths from entering. This design ensures that sampling can only be carried out within a specific water depth range: when the depth is insufficient, the bottom ring 7 and the double groove 12 remain sealed; when the depth is too large, the top ring 8 and the double groove 12 form a new seal. This dual protection mechanism guarantees the accuracy of sampling and ensures that each sampling can accurately reflect the water quality conditions at the target water depth. Environmental engineering personnel can conduct highly accurate water quality sampling in various complex water environments, improving the reliability of sampling data.

[0027] Please refer to Figures 5 to 11, in order to fix and add a connection mechanism between multiple water storage pipes 1, the connection mechanism includes a fixing block 24, a side rod 25, a clamping sleeve 26, an intermediate rod 27 and an insertion block 28. Fixing blocks 24 are installed at both ends of each water storage pipe 1 respectively. A plurality of side rods 25 are installed on each fixing block 24 respectively. The plurality of side rods 25 are connected to the clamping sleeve 26. A plurality of insertion blocks 28 are equidistantly installed at both ends of the intermediate rod 27 respectively. The plurality of insertion blocks 28 are respectively slidably connected in the clamping sleeve 26. A plurality of transverse holes 29 are equidistantly formed in the side wall of each clamping sleeve 26 respectively. A transverse rod 30 is slidably arranged in each transverse hole 29 respectively. A transverse spring 31 is arranged on each transverse rod 30 respectively. The transverse spring 31 abuts in the transverse hole 29. A plurality of insertion grooves 32 are formed in the side wall of the insertion block 28. The transverse rod 30 is stuck in the insertion groove 32. A telescopic rod 33 is slidably arranged in the plurality of insertion blocks 28. A plurality of unlocking sleeves 34 are equidistantly arranged on the telescopic rod 33. The number of the unlocking sleeves 34 is the same as that of the insertion blocks 28 and they are arranged staggeredly. Round corners 35 are formed at both ends of each unlocking sleeve 34 respectively. An expansion sleeve 36 is arranged on the transverse rod 30. The unlocking sleeve 34 abuts against the expansion sleeve 36. A telescopic groove 37 is formed in the clamping sleeve 26. The telescopic rod 33 is slidably connected in the telescopic groove 37. An inner embedding groove 38 is formed in the outer wall of the clamping sleeve 26. A rotating sleeve 39 is slidably arranged in the inner embedding groove 38. The rotating sleeve 39 and the clamping sleeve 26 are coaxially arranged. An inner disc 40 is provided with internal threads in the rotating sleeve 39. The inner disc 40 is installed on the telescopic rod 33.

[0028] Working principle: During the operation of the water quality sampling device in environmental engineering, selecting an appropriate intermediate rod 27 is a crucial step to ensure sampling accuracy. After selecting a suitable intermediate rod 27, the next step is to connect the water storage pipes 1 at both ends. First, the operator needs to rotate the rotating sleeve 39. The design of the rotating sleeve 39 cleverly utilizes its socket connection with the embedded groove 38 to ensure that the rotating sleeve 39 can rotate coaxially with the clamping sleeve 26. This design not only simplifies the operation but also improves the stability and accuracy of the connection. At the same time, the threaded connection between the internal disk 40 and the rotating sleeve 39 provides precise adjustment capabilities. More importantly, the limit between the telescopic rod 33 and the telescopic groove 37 ensures the smooth sliding of the telescopic rod 33 in the vertical direction. Next, the operator needs to press each unlocking sleeve 34 against the expanding sleeve 36 respectively. When the unlocking sleeve 34 is adjusted in place, the transverse spring 31 will be compressed. Under the action of the transverse spring 31, multiple transverse rods 30 will expand along the preset transverse holes 29. This expansion mechanism not only increases the connection stability but also prepares for the subsequent locking process. The expansion process of the transverse rods 30 requires the operator to maintain a stable hand movement to ensure that all the transverse rods 30 expand evenly and prepare for the subsequent locking. Subsequently, the operator needs to carefully insert the insertion block 28 into the clamping sleeve 26. After the insertion is completed, the operator needs to rotate the rotating sleeve 39 in the reverse direction. The unlocking sleeve 34 will rotate in the reverse direction accordingly. Under the elastic force of the transverse spring 31, multiple transverse rods 30 will quickly insert into the insertion slots 32. The final result of this chain reaction is to firmly lock the insertion block 28 and the clamping sleeve 26 together, thus realizing the stable connection of the water storage pipes 1 at both ends.

[0029] Through this series of carefully designed steps and mechanisms, the operator can flexibly adjust the positions of the two water storage pipes 1 at different water depths. This adjustment ability not only improves the sampling accuracy but also increases the adaptability of the device in complex water environments. Finally, this precise depth adjustment ability enables researchers to conduct precise sampling for specific water layers, thereby obtaining more reliable and valid water quality data, providing strong support for environmental engineering detection and research.
