Description

Technical Field

[0001] The utility model relates to the technical field of environmental detection, in particular to an environmental detection sampling device. Background Art

[0002] Environmental monitoring refers to the activities of environmental monitoring agencies to monitor and measure environmental quality. Environmental monitoring is to determine the status of environmental pollution and the level of environmental quality by monitoring and measuring indicators that reflect environmental quality. The content of environmental monitoring mainly includes the monitoring of physical indicators, chemical indicators and ecosystems. Environmental monitoring is the basis for scientific management of the environment and environmental law enforcement supervision, and is an indispensable basic work for environmental protection. The core goal of environmental monitoring is to provide data on the current status and changing trends of environmental quality, judge environmental quality, and evaluate current major environmental problems. When judging environmental quality, environmental monitoring requires sampling and processing of substances in the environment, such as soil sampling and water source sampling. Soil sampling refers to the extraction of deep soil through a sampling device, and then the physical and chemical analysis of the extracted soil is carried out to determine environmental problems.

[0031] The present invention is further described below with reference to the accompanying drawings and specific embodiments:

[0032] like Figures 1 to 10As shown, an environmental detection sampling device comprises an internally hollow sampling tube 1 and a support plate 2, a sleeve 3 is provided in the center of the support plate 2, the sampling tube 1 is inserted into the sleeve 3, and the sleeve 3 is threadedly connected to the sampling tube 1; a collection box 4 is provided on the top of the sampling tube 1, and a feeding hole 5 is provided at the bottom center of the collection box 4, and the collection box 4 is communicated with the sampling tube 1 through the feeding hole 5; a sampling component is provided in the sampling tube 1, and the sampling component comprises a rotating shaft 6, and the rotating shaft 6 is connected to a driving component, and a sampling blade 7 is provided on the outside of the rotating shaft 6, and the sampling blade 7 is spiral-shaped, and the rotating shaft 6 passes through the feeding hole 5 at the bottom of the collection box 4 and extends upward into the collection box 4, and the part of the rotating shaft 6 located in the collection box 4 is provided with Scraper 8; a discharge pipe 9 is provided on one side of the sampling tube 1, and the top end of the discharge pipe 9 passes through the outer wall of the collection box 4 and is connected to the collection box 4. By providing the discharge pipe 9, the collected soil can be conveniently discharged for collection; further, a collection port 10 is provided on the outer wall of one side near the bottom end of the sampling tube 1, and a sealing assembly is provided on the sampling tube 1, and the sealing assembly includes an insertion rod 11 and a baffle 12 arranged at the bottom end of the insertion rod 11. The top of the collection port 10 is connected to a slide groove 13, and the top of the slide groove 13 is connected to a socket 14. The baffle 12 is slidably set in the slide groove 13, and the insertion rod 11 is slidably set in the socket 14. The top of the insertion rod 11 passes through the top of the socket 14 and is connected to an adjustment assembly.

[0033] Through the above-mentioned setting structure, when the sampling tube 1 is rotated forward, the rotation between the sleeve 3 and the sampling tube 1 will drive the sampling tube 1 to move downward under the action of the thread between the sleeve 3 and the sampling tube 1. When the sampling tube 1 is inserted into the soil to a suitable depth, the baffle 12 at its bottom end is lifted by moving the insertion rod 11 upward, and the baffle 12 is stored in the slide groove 13. At this time, the collection port 10 is in an open state, and then the soil can be collected through the collection port 10 through the operation of the sampling component. After collection, the baffle 12 is reset to re-close the collection port 10. In this way, when the sampling tube 1 is inserted into the soil and withdrawn from the soil, the mutual influence of soils at different depths is avoided. Therefore, the utility model can avoid the mixing of shallow soil when collecting deep soil, thereby improving the accuracy of the final detection result.

[0034] Please refer again Figure 6 The baffle 12 is arc-shaped, the collection port 10 is a rectangular hole that penetrates the wall of the sampling tube 1, and the height of the baffle 12 is not less than the height of the collection port 10. Through the above arrangement, the portion of the baffle 12 that is higher than the collection port 10 is always located in the chute 13, making the baffle 12 more stable during the up and down movement.

[0035] Please refer again Figure 3 、 Figure 5 and Figure 6The adjustment assembly includes an adjusting rod 15. A groove 16 is provided on the side of the top of the socket 14 away from the central axis of the sampling tube 1. The groove 16 is connected to the socket 14. The groove 16 passes through the outer wall of the sampling tube 1, and the top of the insertion rod 11 passes through the socket 14 and extends upward into the groove 16; an adjusting plate 17 is fixedly connected to the position of the outer wall of the sampling tube 1 corresponding to the groove 16, and a long hole 18 is opened on the adjusting plate 17 along the length direction of the sampling tube 1. An adjusting ring 19 is provided at one end of the adjusting rod 15, and the adjusting ring 19 is rotatably set on the insertion rod 11. The other end of the adjusting rod 15 passes through the groove 16 and the long hole 18 and extends to the outside of the adjusting plate 17. The part of the adjusting rod 15 located outside the adjusting plate 17 is provided with a handle ball 20.

[0036] By setting up the sealing component and the adjustment component, the handle ball 20 is held to move the adjustment rod 15 up or down along the long hole 18 on the adjustment plate 17, and the adjustment rod 15 drives the insertion rod 11 to move up or down along the insertion hole 14, and then the adjustment rod 15 drives the insertion rod 11 to move up or down, and then the insertion rod 11 drives the baffle 12 at the bottom end to move up or down.

[0037] It is worth mentioning that an upper limit slot 21 is provided at the top of one side of the elongated hole 18, and a lower limit slot 22 is provided at the bottom of one side of the elongated hole 18. Both the upper limit slot 21 and the lower limit slot 22 are connected to the elongated hole 18, and an identification plate 23 is provided on the other side of the elongated hole 18. Among them, the identification plate 23 is marked with "open" and "close" fonts. The position of the upper limit slot 21 corresponds to the "open" on the identification plate 23, and the position of the lower limit slot 22 corresponds to the "close" on the identification plate 23. This makes it easier for staff to more intuitively determine whether the collection port 10 is in an open or closed state, reducing the risk of accidentally opening or closing the collection port 10 and facilitating operation.

[0038] Furthermore, since both the upper limit slot 21 and the lower limit slot 22 are connected to the long hole 18, when the adjusting rod 15 moves upward along the long hole 18 and enters the upper limit slot 21, the state is as follows: Figure 9 As shown, at this time, the baffle 12 is lifted and stored in the chute 13, the collection port 10 is in the open state, and the soil can enter the trough sampling tube 1 through the collection port 10; when the adjusting rod 15 moves downward along the long hole 18 and enters the lower limit slot 22, the state is as shown in FIG. Figure 10 As shown, at this time, the baffle 12 closes the collection port 10.

[0039] Please refer again Figure 1 and Figure 2Two connecting blocks 24 are symmetrically arranged on the outer wall of the sampling tube 1. A grip 25 is provided on each side of the connecting blocks 24 facing away from the sampling tube 1. The grip 25 has a non-slip cover 26 on its surface. By providing the grip 25, forward rotation of the grip 25 drives the sampling tube 1 in the forward direction. This rotation, driven by the threads between the sleeve 3 and the sampling tube 1, causes the sampling tube 1 to move downward, allowing the sampling tube 1 to be inserted into the soil. Conversely, reverse rotation of the grip 25 drives the sampling tube 1 in the reverse direction. This rotation, driven by the threads between the sleeve 3 and the sampling tube 1, causes the sampling tube 1 to move upward, allowing the sampling tube 1 to be withdrawn from the soil.

[0040] Furthermore, a drill bit 27 is provided at the bottom end of the sampling tube 1. The drill bit 27 is conical in shape, and an integral protrusion 28 is provided at the top end of the drill bit 27. The protrusion 28 is threadedly connected to the inner wall of the sampling tube 1. The provision of the drill bit 27 facilitates screwing the sampling tube 1 into deep soil layers for sampling, and also facilitates the detachable connection between the drill bit 27 and the sampling tube 1.

[0041] In this embodiment, legs 29 are symmetrically provided on the left and right sides of the lower surface of the support plate 2. The legs 29 are triangular in shape, and a fixing rod 30 is provided on the side of each leg 29 away from the sampling tube 1. A through hole 31 is provided on the support plate 2, and the fixing rod 30 passes through the through hole 31. The top of the fixing rod 30 is fixedly connected to a limit block 32. By providing two triangular legs 29, the legs 29 can provide good support for the support plate 2, and when the device is stored after use, it is convenient to place it. The bottom end of the fixing rod 30 is pointed. When the fixing rod 30 is inserted into the soil, the support plate 2 can be fixed more stably, preventing the staff from moving the collection position during the soil collection process, which may affect the sampling.

[0042] Please refer again Figure 3 and Figure 4 The number of the scrapers 8 is set to two, and the two scrapers 8 are symmetrically distributed on the outer peripheral surface of the rotating shaft 6. The bottom surface of the scraper 8 is arranged to fit the bottom surface of the inner cavity of the collection box 4. When the sampling assembly is working, the scraper 8 rotates with the rotating shaft 6.

[0043] In this embodiment, the drive assembly includes a motor 33, which is arranged at the top of the aggregate box 4. The output shaft of the motor 33 passes through the top of the aggregate box 4 and extends downward into the aggregate box 4. The bottom end of the output shaft of the motor 33 is connected to the top of the rotating shaft 6 through a coupling 34. The motor 33 drives the rotating shaft 6 to rotate, so that the spiral sampling blade 7 drives the soil to move upward in a spiral until it enters the aggregate box 4 through the feed hole 5 for collection. As the scraper 8 rotates, the soil entering the aggregate box 4 is continuously pushed into the discharge pipe 9 by the scraper 8, and then the soil is discharged from the discharge pipe 9.

[0044] Please refer again Figure 8 The top of the insertion rod 11 is provided with an integral mounting post 35, and the adjustment ring 19 is movably mounted on the mounting post 35. A retaining spring 36 is provided on the side of the adjustment ring 19 away from the insertion rod 11. The mounting post 35 is provided with an annular groove 37 that cooperates with the retaining spring 36, and the retaining spring 36 is engaged in the annular groove 37. With this arrangement, the adjustment rod 15 can rotate left and right relative to the insertion rod 11, but the adjustment rod 15 cannot slide up and down along the insertion rod 11. When the operator adjusts the sealing assembly, the adjustment rod 15 can enter the upper limit slot 21 or the lower limit slot 22 from the elongated hole 18. Similarly, the adjustment rod 15 can also enter the elongated hole 18 from the upper limit slot 21 or the lower limit slot 22, facilitating operation.

[0045] How to use this product:

[0046] Step 1: After the staff has selected the sampling location, they place the support plate 2 at the selected location and insert the two fixing rods 30 into the soil to fix the support plate 2. At this time, the adjustment rod 15 is placed in the lower limit groove 22, and the baffle 12 closes the sampling port 10.

[0047] Step 2: The staff can then hold the anti-slip sleeve 26 and rotate the handle 25 forward. The rotation of the handle 25 drives the sampling tube 1 to rotate forward. At the same time, the sampling tube 1 drives the drill bit 27 at the bottom to rotate. When the sampling tube 1 is rotated forward, the rotation between the sleeve 3 and the sampling tube 1 will drive the sampling tube 1 downward under the action of the thread, so that the sampling tube 1 can be extended into the soil.

[0048] Step 3: When the sampling tube 1 is inserted to the appropriate depth, hold the handle ball 20 to withdraw the adjustment rod 15 from the lower limit slot 22, then move the adjustment rod 15 upward along the long hole 18 and enter the upper limit slot 21, the baffle 12 is lifted, and the collection port 10 is switched from the closed state to the open state, and the soil enters the sampling tube 1 through the collection port 10;

[0049] Step 4: The motor 33 is started to rotate the shaft 6, so that the spiral sampling blade 7 drives the soil in the sampling tube 1 to move upward in a spiral until it enters the collection box 4 through the feeding hole 5 for collection. As the scraper 8 rotates, the soil in the collection box 4 is continuously pushed into the discharge pipe 9 by the scraper 8, and then the soil is discharged from the discharge pipe 9;

[0050] Step 5: After the collection is completed, the motor 33 is stopped, and the handle ball 20 is held to withdraw the adjustment rod 15 from the upper limit slot 21. Then the adjustment rod 15 moves downward along the long hole 18 and enters the lower limit slot 22. The baffle 12 falls and resets. The collection port 10 switches from the open state to the closed state. Then the staff rotates the sampling tube 1 in the reverse direction and withdraws the sampling tube 1 from the soil, so as to avoid the mixing of shallow soil when collecting deep soil.

[0051] Step 6: Finally, pull out the fixing rod 30, clean the device after use, and store it after cleaning.

[0052] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
