Description

Technical Field

[0001] This invention is a soil sampling device for environmental monitoring, belonging to the field of environmental monitoring equipment technology. Background Technology

[0002] In environmental monitoring, soil sampling is a fundamental step in conducting analysis of soil composition, pollution levels, and soil conditions. The accuracy, convenience, and completeness of sampling at different depths directly affect the scientific validity and reliability of subsequent test results. Currently, most commercially available soil sampling devices for environmental monitoring employ an integrated sampling drill cylinder structure, which presents numerous drawbacks in actual sampling operations.

[0003] Traditional sampling devices often have integrated sampling components that cannot be disassembled. After sampling, they can only obtain soil samples from different depths mixed inside the drill pipe. If the testing work requires separate analysis of soil layers at a specific depth, staff need to manually separate the mixed samples. This is not only cumbersome and time-consuming, but also prone to cross-contamination of samples, leading to deviations in the test data and making it difficult to meet the needs of refined environmental testing.

[0004] In addition, some simple soil sampling devices rely on manual drilling, which is labor-intensive and makes it difficult to complete sampling operations in deeper soil layers. While some mechanized sampling devices can achieve power drilling, their sampling structure has poor adaptability and cannot flexibly adjust the sampling depth and the number of sampling units according to the testing needs, resulting in low versatility and practicality of the devices.

[0005] Therefore, developing a soil sampling device for environmental monitoring that can disassemble the sampling unit, accurately obtain soil samples at different depths, and has a stable sampling process, convenient assembly and disassembly, and high sampling efficiency has become an urgent technical problem to be solved in the field of environmental monitoring.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-10This invention provides a technical solution for a soil sampling device for environmental protection testing, including a base 1. A sampling hole 2 is provided at the center of the top of the base 1. A sampling mechanism is placed inside the sampling hole 2. A column 4 is provided on the top of the base 1 and outside the sampling hole 2. A mounting frame 5 is fixed on the top of the column 4. A push cylinder 6 is installed on the top of the mounting frame 5. A push plate is connected to the bottom output end of the push cylinder 6. The push plate is adapted to the sampling mechanism.

[0028] See Figures 4-6 The sampling mechanism includes a drill bit 10, a support frame 7 is installed at the top center of the drill bit 10, and several mounting grooves 31 are opened on the outer side surface of the support frame 7. Sampling units are installed inside the mounting grooves 31. In use, the device is moved to the sampling position, and then the sampling mechanism with the drill bit 10 is placed into the sampling hole 2. The guide plate 8 on the sampling mechanism is slidably connected to the guide hole 3 on the inner wall of the sampling hole 2 to realize the vertical guidance of the sampling mechanism. At the same time, the positioning block 11 at the bottom of the drill bit 10 is initially anchored into the soil layer. Then, the support frame 7 is pushed by the jacking cylinder 6 to force the sampling mechanism to drill into the soil layer. During the process of the drill bit 10 cutting into the soil layer, the soil layer enters several sampling cylinders 28 in sequence through the cutting hole 12.

[0029] See Figure 7 , Figure 10 The sampling unit includes several fixed plates 13 evenly spaced and fixed to the inner wall of the mounting groove 31. Several through holes 15 are formed on each fixed plate 13. An inner ring 14 is fixed to the inner wall of each fixed plate 13. A movable plate 17 is vertically slidably connected to the outer wall of the inner ring 14. The movable plate 17 is located below the fixed plates 13. Several pads 18, adapted to the through holes 15, are fixed to the top of the movable plate 17. A locking member is provided on one side of the movable plate 17, and the locking member is locked to the outer surface of the support frame 7. The sampling unit also includes several sampling cylinders 28. The sampling cylinder 28 is installed below the movable plate 17. The outer surface of the sampling cylinder 28 is provided with a plug-in block 29. One end of the plug-in block 29 is inserted into the outer surface of the support frame 7. The plug-in block 29 is provided with a through hole 30 at the outer end of the support frame 7. A groove 16 is provided between the fixing plate 13 and the inner ring 14 to fit the bottom end of the sampling cylinder 28. After sampling is completed, the hoisting action can be achieved by connecting a hoisting rope between the push plate and the support frame 7. After the support frame 7 is removed, the sampling cylinder 28 at the corresponding depth can be disassembled according to the scale on the outer surface of the sampling cylinder 28.

[0030] See Figure 8-9The locking component includes a connecting plate 19 and a movable column 21. The end of the connecting plate 19 is fixedly connected to a support plate 20. A sleeve 22 is placed on the support plate 20. One side of the sleeve 22 is fixed to the end of the movable column 21. A movable rod 23 is rotatably connected inside the sleeve 22. Locking plate 24 and locking column 25 are fixed to both ends of the movable rod 23, respectively. A sliding column 32 is slidably connected inside the locking column 25. A top plate 33 and a second locking plate are respectively provided at both ends of the sliding column 32. 27. The top plate 33 and the second locking plate 27 are movably connected to the sliding column 32 via a rotating shaft 26. The bottom end of the sliding column 32, carrying the second locking plate 27, passes through the through hole 30 to the underside of the insertion block 29. The second locking plate 27 is pressed against the underside of the insertion block 29. The outer surface of the support frame 7 has an insertion hole, and the inside of the insertion hole has a locking hole. The inner wall of the locking hole has an embedded groove, which is perpendicularly staggered with the locking hole. Both the locking hole and the recessed groove are adapted to the locking plate 24. The connecting plate 19 is fixed to the outer surface of the movable plate 17, and the movable column 21 is movably connected to the outer surface of the movable plate 17. In use, rotating the top plate 33 drives the rotating shaft 26 and the locking plate 27 to rotate, causing the locking plate 27 to rotate and reset, releasing the contact limit with the plug block 29. Then, pulling up the top plate 33 and the sliding column 32 causes the locking plate 27 to separate from the plug block 29. Next, rotating the locking column 25... Rotating the movable rod 23 and the locking plate 24 causes the locking plate 24 to misalign with the groove on the support frame 7. At this time, the locking plate 24 matches the locking hole, allowing the locking plate 24 to be pulled out from the locking hole and separated from the support frame 7. Simultaneously, it can drive the movable plate 17 to rotate and reset, so that the pad 18 on the top of the movable plate 17 matches the through hole 15 on the fixed plate 13, pushing the movable plate 17 up to below the fixed plate 13, allowing the sampling tube 28 to be taken out for soil layer testing.

[0031] See Figures 1-2 The inner wall of the sampling hole 2 is provided with a plurality of guide holes 3, and the outer surface of the support frame 7 is provided with a plurality of guide plates 8, which are slidably adapted to the guide holes 3; the design of the guide plates 8 and the guide holes 3 improves the stability of the sampling mechanism moving in the sampling hole 2.

[0032] See Figure 1 The top and bottom sides of the support frame 7 are respectively provided with a docking plate 9 and a docking groove. The docking groove is snapped into the docking plate 9. The design of the docking plate 9 and the docking groove makes it easy to splice the upper and lower support frames 7 and extend the length of the support frame 7. After the splicing is completed, the stability of the two support frames 7 can be strengthened by bolts.

[0033] See Figure 4 A positioning block 11 is provided at the center of the bottom of the drill bit 10, and a cutting hole 12 connected to the sampling cylinder 28 is provided at the bottom of the drill bit 10 and outside the positioning block 11. Through the design of the cutting hole 12, when the drill bit 10 drills into the soil layer, the cutting hole 12 can perform soil shearing work, so that the soil layer can quickly enter the sampling cylinder 28 through the cutting hole 12 to realize the sampling work.

[0034] In use, the device is moved to the sampling position. Then, the sampling mechanism with drill bit 10 is placed into the sampling hole 2. The guide plate 8 on the sampling mechanism is slidably connected to the guide hole 3 on the inner wall of the sampling hole 2, providing vertical guidance for the sampling mechanism. Simultaneously, the positioning block 11 at the bottom of the drill bit 10 is initially anchored into the soil layer. Then, the jacking cylinder 6 pushes the support frame 7 to force the sampling mechanism to drill into the soil layer. During the process of the drill bit 10 cutting into the soil layer, the soil layer enters several sampling cylinders 28 sequentially through the cutting holes 12. At the same time, the upper and lower sets of support frames 7 can be spliced ​​together using the connecting plate 9 to extend the length of the support frame 7. After splicing, the stability of the two sets of support frames 7 can be strengthened using bolts. After sampling, the lifting action can be achieved by connecting a lifting rope between the jacking plate and the support frame 7. After the support frame 7 is removed, it can be used to collect several samples. The sampling cylinder 28 is disassembled according to the scale on the outer surface of the cylinder 28 to the corresponding depth. Specifically, the rotatable top plate 33 drives the rotating shaft 26 and the second locking plate 27 to rotate, so that the second locking plate 27 rotates and resets to release the contact limit with the plug block 29. Then, the top plate 33 and the sliding column 32 are pulled up to separate the second locking plate 27 from the plug block 29. Next, the locking column 25 is rotated to drive the movable rod 23 and the first locking plate 24 to rotate, so that the first locking plate 24 is misaligned with the inner groove on the support frame 7. At this time, the first locking plate 24 is matched with the locking hole, so the first locking plate 24 can be pulled out from the locking hole to separate from the support frame 7. At the same time, the movable plate 17 can be rotated and reset, so that the pad 18 on the top of the movable plate 17 is matched with the through hole 15 on the fixed plate 13, and the movable plate 17 is pushed up to the bottom of the fixed plate 13, so that the sampling cylinder 28 can be taken out for soil layer testing.

[0035] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
