Abstract
Description
Technical Field
[0001] This utility model belongs to the field of soil sampling technology, and more specifically, it relates to a sampling device for soil pollution investigation. Background Technology
[0002] Soil is the surface of the Earth's landmass, composed of minerals, organic matter, water, air, and organisms; soil is the fertile, loose top layer of land that can support plant growth; soil pollutants can be broadly classified into two categories: inorganic pollutants and organic pollutants; sampling and investigation are necessary during soil remediation.
[0003] Existing sampling devices mostly consist of a rotating rod connected to a sampling tube. During sampling, the rotating rod is rotated while the sampling tube is inserted into the soil for rotation sampling. However, since the rotating rod is connected to the sampling tube through multiple sets of bolted connection components, when maintenance or replacement of the sampling tube is required, multiple sets of bolted connection components must be disassembled one by one, which is time-consuming and labor-intensive, reducing disassembly efficiency. Utility Model Content
[0004] This utility model provides a sampling device for soil pollution investigation, which can axially separate the rotating rod and sampling cylinder by rotating the rotating rod and sampling cylinder in the opposite direction until the rotating clamp and the through groove are aligned vertically, thereby improving the disassembly efficiency.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a sampling device for soil pollution investigation is provided, including a support, a rotating rod, and a sampling tube. The rotating rod passes through the support in the vertical direction, and the lower end of the rotating rod is provided with a rotating locking part that protrudes outward. The sampling tube is positioned with its opening facing downward, and the upper end face of the sampling tube is provided with a rotating locking seat for connecting with the rotating locking part. The upper end face of the rotating locking seat is provided with a through groove for the axial entry of the rotating locking part, and a rotating locking cavity that communicates with the through groove and extends into the interior of the rotating locking seat. The rotating locking cavity is used to accommodate the rotating locking part and can be rotated and positioned with the rotating locking part.
[0006] In one possible implementation, several locking parts are provided and arranged at intervals on the outer periphery of the rotating rod, and several through slots are also provided, each corresponding to one of the locking parts.
[0007] In one possible implementation, the rotating bracket is provided with a sealing element that engages with the slot and is located on one side of the rotating part, for preventing the rotating part from disengaging from the rotating bracket.
[0008] In some embodiments, the sealing element includes a sealing block and a magnet. The sealing block is used to engage with a slot. The magnet is disposed on the top surface of the sealing block and above the rotary seat to attract the rotary seat.
[0009] In one possible implementation, a through hole is axially provided on the rotating rod, and a pusher extending into the sampling cylinder is provided in the through hole. The pusher is capable of axially moving and pushing the soil in the sampling cylinder to the outside of the sampling cylinder.
[0010] In some embodiments, the pusher includes a push-pull rod and a push plate. The push-pull rod is slidably connected in the through hole and is disposed through the top wall of the rotary seat and the sampling cylinder. The push plate is connected to the lower end of the push-pull rod and is located in the sampling cylinder.
[0011] In some embodiments, the upper end of the push-pull rod is threaded with a threaded cap for contacting and engaging with the upper end face of the rotating rod to prevent the push-pull rod from disengaging from the rotating rod.
[0012] In one possible implementation, a radially extending rotary handle is provided on the outer peripheral wall of the rotating rod, and the rotary handle is located near the upper end of the rotating rod.
[0013] In one possible implementation, the top of the support is provided with a guide sleeve that is slidably fitted around the outer periphery of the rotating rod. A locking bolt extending into the guide sleeve is threaded onto the outer peripheral wall of the guide sleeve. The locking bolt is used to engage with the outer peripheral wall of the rotating rod to lock the axial position of the rotating rod.
[0014] In one possible implementation, the support has a support leg located outside the sampling tube and extending downward, with several support legs spaced apart in the circumferential direction of the sampling tube, and the lower end of the support leg is a tapered end.
[0015] Compared with the prior art, the soil pollution investigation sampling device provided in this embodiment can quickly disassemble the rotating rod and the sampling tube when it is necessary to disassemble and replace the sampling tube. The rotating rod and the sampling tube are rotated in the opposite direction until the rotating clamp and the through groove are aligned vertically. Then, the rotating clamp and the rotating clamp seat are separated axially, which realizes the quick disassembly of the rotating rod and the sampling tube and improves the disassembly efficiency.

[0027] Please see Figures 1 to 6The sampling device for soil pollution investigation provided by this utility model will now be described. The sampling device for soil pollution investigation includes a support 10, a rotating rod 20, and a sampling tube 30. The rotating rod 20 passes through the support 10 in the vertical direction, and the lower end of the rotating rod 20 is provided with a rotating locking part 21 that protrudes outward. The sampling tube 30 is set with its opening facing downward. The upper end surface of the sampling tube 30 is provided with a rotating locking seat 40 for connecting with the rotating locking part 21. The upper end surface of the rotating locking seat 40 is provided with a through groove 41 for the axial entry of the rotating locking part 21, and a rotating locking cavity 42 that communicates with the through groove 41 and extends into the interior of the rotating locking seat 40. The rotating locking cavity 42 is used to accommodate the rotating locking part 21 and can be rotated and positioned with the rotating locking part 21.
[0028] Furthermore, the lower end of the sampling tube 30 is provided with teeth, which facilitates the insertion and rotation of the sampling tube 30 into the soil.
[0029] This application provides a sampling device for soil pollution investigation. In actual use, when it is necessary to disassemble and replace the sampling cylinder 30, the rotating rod 20 and the sampling cylinder 30 are rotated in the opposite direction until the locking part 21 and the through groove 41 are aligned vertically. Then, the locking part 21 and the locking seat 40 are separated axially, which realizes the quick disassembly of the rotating rod 20 and the sampling cylinder 30 and improves the disassembly efficiency.
[0030] When using it, you can first use external tools such as wooden plugs to insert into the through groove 41 to restrict the alignment of the rotating part 21 with the through groove 41 and prevent the rotating part 21 from coming out of the through groove 41. Insert the sampling tube 30 into the soil, apply downward force to the rotating rod 20 while rotating the rotating rod 20 (the direction of rotation should be the same as the direction of rotation of the rotating rod 20 when the rotating part 21 and the rotating seat 40 are installed), so that the sampling tube 30 rotates to take a sample.
[0031] The installation process is as follows: First, insert the end of the rotating rod 20 with the locking part 21 into the through groove 41, and rotate the rotating rod 20 so that the locking part 21 is inserted into the locking cavity 42, that is, the locking part 21 is misaligned with the through groove 41, and then the locking part 21 is limited in the locking cavity 42, which restricts the relative axial position of the rotating rod 20 and the sampling cylinder 30, and prevents the rotating rod 20 from separating from the sampling cylinder 30.
[0032] Compared with the prior art, the soil pollution investigation sampling device provided in this embodiment can quickly disassemble the rotating rod 20 and the sampling cylinder 30 when it is necessary to disassemble and replace the sampling cylinder 30. The rotating rod 20 and the sampling cylinder 30 are rotated in the opposite direction until the rotating clamp 21 and the through groove 41 are aligned vertically. Then, the rotating clamp 21 and the rotating clamp seat 40 are separated axially, which realizes the quick disassembly of the rotating rod 20 and the sampling cylinder 30 and improves the disassembly efficiency.
[0033] In one possible implementation, the aforementioned rotating locking part 21 adopts as follows: Figure 3 and Figure 4 The structure shown is described in the following document. Figure 3 and Figure 4Several locking parts 21 are provided and are arranged at intervals on the outer periphery of the rotating rod 20. Several slots 41 are also provided and correspond one-to-one with the locking parts 21.
[0034] Specifically, several locking parts 21 are arranged at intervals around the axis of the rotating rod 20. The rotating rod 20 drives the locking parts 21 into the through groove 41, and then rotates 10 to 20 degrees into the locking cavity 42, so that the locking parts 21 are deeply inserted into the locking cavity 42, that is, the locking parts 21 are misaligned with the through groove 41, and thus the locking parts 21 are limited in the locking cavity 42, avoiding axial separation between the rotating rod 20 and the sampling cylinder 30.
[0035] In one possible implementation, the aforementioned rotating card holder 40 adopts as follows: Figures 1 to 4 The structure shown is described in the following document. Figures 1 to 4 The rotating bracket 40 is provided with a sealing member 50 that is inserted and engaged with the through groove 41 and located on one side of the rotating bracket 21, which is used to restrict the rotating bracket 21 from disengaging from the rotating bracket 40.
[0036] Specifically, the sealing member 50 blocks the through groove 41 and extends to the bottom wall of the through groove 41 to limit the rotation clamp 21, preventing the rotation clamp 21 from aligning with the through groove 41 and dislodging it, so that the rotation clamp 21 is stably located in the rotation clamp cavity 42, thereby improving the stability of the connection between the rotation clamp seat 40 and the rotating rod 20.
[0037] Optionally, the sealing component 50 includes a sealing block 51 and a magnet 52. The sealing block 51 is used to insert and cooperate with the through groove 41. The magnet 52 is disposed on the top surface of the sealing block 51 and located above the rotating seat 40, and is used to attract the rotating seat 40.
[0038] Optionally, the sealing element 50 is a bolt threaded onto the bottom wall of the passage groove 41.
[0039] Optionally, the sealing element 50 is a rubber plug inserted into the through groove 41, and the rubber plug abuts against the inner peripheral wall of the through groove 41.
[0040] In some embodiments, see Figures 1 to 4 The sealing component 50 includes a sealing block 51 and a magnet 52. The sealing block 51 is used to insert and cooperate with the through groove 41. The magnet 52 is disposed on the top surface of the sealing block 51 and located above the rotating seat 40, and is used to attract the rotating seat 40.
[0041] Specifically, the blocking block 51 is inserted into the through groove 41 and extends to the bottom wall of the through groove 41 to limit the rotation clamp 21, preventing the rotation clamp 21 from aligning with the through groove 41 and coming out, so that the rotation clamp 21 is stably placed in the rotation clamp cavity 42, and the magnet 52 is attracted to the top surface of the rotation clamp seat 40 to ensure the stability of the blocking block 51 inserted into the through groove 41.
[0042] When it is necessary to separate the rotary seat 40 and the rotating rod 20, simply pull the sealing piece 50 upwards and rotate the rotating rod 20 and the rotary seat 40 in the opposite direction to align the passage groove 41 with the rotary seat 21.
[0043] In one possible implementation, the aforementioned lever 20 adopts the following... Figure 1 , Figure 3 and Figure 5 The structure shown is described in the following document. Figure 1 , Figure 3 and Figure 5 A through hole is provided axially on the rotating rod 20, and a pusher 60 extending into the sampling cylinder 30 is provided in the through hole. The pusher 60 can move axially to push the soil in the sampling cylinder 30 to the outside of the sampling cylinder 30.
[0044] Specifically, during the sampling process in the sampling tube 30, the soil entering the sampling tube 30 will push against the pusher 60. After sampling is completed, when it is necessary to release the soil in the sampling tube 30, simply push the pusher 60 downwards to push the soil in the sampling tube 30 downwards, which facilitates the release of the soil in the sampling tube 30.
[0045] In some embodiments, see Figures 1 to 5 The pusher 60 includes a push-pull rod 61 and a push plate 62. The push-pull rod 61 is slidably connected in the through hole and is disposed through the top wall of the rotating seat 40 and the sampling cylinder 30. The push plate 62 is connected to the lower end of the push-pull rod 61 and is located in the sampling cylinder 30.
[0046] Specifically, the push plate 62 slides along the axial direction of the sampling cylinder 30. During the sampling process, the soil entering the sampling cylinder 30 pushes against the push plate 62. After sampling is completed, when it is necessary to release the soil in the sampling cylinder 30, simply push the push rod 61 downwards, causing the push plate 62 to push the soil in the sampling cylinder 30 downwards, thus facilitating the release of the soil in the sampling cylinder 30.
[0047] In some embodiments, see Figure 1 , Figure 3 and Figure 5 The upper end of the push-pull rod 61 is threaded with a threaded cap 70, which is used to contact and engage with the upper end face of the rotating rod 20 to prevent the push-pull rod 61 from disengaging from the rotating rod 20.
[0048] Specifically, the threaded cap 70 is threaded onto the upper end of the push-pull rod 61 to prevent the push-pull rod 61 from disengaging from the rotating rod 20. When it is necessary to disassemble the pusher 60, simply unscrew the threaded cap 70 to disengage it from the push-pull rod 61, causing the pusher 60 to fall. The pusher 60 can then be pulled out from the lower port of the sampling cylinder 30, which improves the convenience of disassembling the pusher 60.
[0049] In one possible implementation, the aforementioned lever 20 adopts the following... Figure 1 , Figure 3 and Figure 5 The structure shown is described in the following document. Figure 1 , Figure 3 and Figure 5 A radially extending rotating handle 22 is provided on the outer peripheral wall of the rotating rod 20, and the rotating handle 22 is located near the upper end of the rotating rod 20.
[0050] Specifically, the rotating handle 22 is provided at intervals around the rotating rod 20. When it is necessary to rotate the rotating rod 20, you only need to apply force to the rotating handle 22 with both hands, which facilitates the rotation of the rotating rod 20.
[0051] In one possible implementation, the aforementioned support 10 adopts the following... Figure 1 and Figure 5 The structure shown is described in the following document. Figure 1 and Figure 5 The top of the support 10 is provided with a guide sleeve 11 that is slidably sleeved on the outer periphery of the rotating rod 20. A locking bolt 80 extending into the guide sleeve 11 is threadedly connected to the outer peripheral wall of the guide sleeve 11. The locking bolt 80 is used to abut against the outer peripheral wall of the rotating rod 20 to lock the axial position of the rotating rod 20.
[0052] Specifically, the guide sleeve 11 is connected to the top of the support 10, and the rotating rod 20 can not only slide within the guide sleeve 11 but also rotate. The locking bolt 80 is radially inserted through the outer peripheral wall of the guide sleeve 11 and extends into the guide sleeve 11. The locking bolt 80 can rotate and abut against the outer peripheral wall of the rotating rod 20 to lock the axial position of the rotating rod 20, which facilitates the movement of the entire device and prevents the rotating rod 20 from detaching from the support 10 during the movement of the device.
[0053] In one possible implementation, the aforementioned support 10 adopts the following... Figure 1 , Figure 3 and Figure 5 The structure shown is described in the following document. Figure 1 , Figure 3 and Figure 5 The support 10 has a support leg 12 located outside the sampling cylinder 30 and extending downward. Several support legs 12 are spaced apart in the circumferential direction of the sampling cylinder 30, and the lower end of the support leg 12 is a tapered end.
[0054] Specifically, the tapered end of the support leg 12 can be inserted into the soil to fix the horizontal position of the support 10, so that the sampling tube 30 is aligned with the sampling position. When the rotating rod 20 is rotated to drive the sampling tube 30 to take a sample, the rotating rod 20 and the support 10 can be prevented from rotating at the same time, which improves the convenience of positioning the sampling tube 30.
[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
