Description

Technical Field

[0001] This invention relates to the field of sampling device technology, specifically to a portable single-walled carbon nanotube sampling device. Background Technology

[0002] Water pollution detection refers to the systematic monitoring, analysis, and assessment of the physical, chemical, and biological characteristics of water bodies (including rivers, lakes, oceans, groundwater, drinking water, industrial wastewater, and domestic sewage) using scientific methods and technologies. This process aims to determine whether the water body is polluted, the degree of pollution, the types and sources of pollutants, and provides data support for water pollution prevention and control, water environment management, and water resource protection. Before conducting water pollution detection, effective sampling of the water body is necessary. Because natural water bodies typically exhibit vertical stratification, with significant differences in the physical, chemical, and biological characteristics of different water layers, surface water is easily affected by the external environment, while bottom water, close to bottom sediments, is easily polluted by pollutants released from the sediment. Therefore, sampling typically extracts mid-layer water, which is less affected by external disturbances and sediment. Mid-layer water is relatively homogeneous and can more stably reflect the overall pollution status of the water body.

[0003] Steep banks near water bodies are often muddy and slippery, sometimes even with loose rocks, making it difficult for sampling personnel to maintain their footing and hindering sampling. Furthermore, because different water bodies have different depths, shallower areas are shallower, and using conventional samplers or sampling bottles can easily touch the riverbed or stir up bottom sediment when inserted into the water, resulting in the introduction of sediment particles into the sample. These particles may adsorb a large amount of pollutants, leading to an overestimation of pollution levels in the test results and failing to reflect the actual pollution status of the water body. When sampling in deep water, it is possible to obtain surface water when the water level is rising and near-bottom water when the water level is falling, resulting in incomparable results from multiple samplings. The water pressure increases with depth in deep water areas, which may cause the device to enter water prematurely during descent, resulting in the mixing of upper-layer water into the sample. This can prevent the collection of the target middle or bottom water, leading to the mistaken collection of surface water as middle-layer water and misjudging stratified pollution.

[0004] Therefore, it is necessary to provide a portable single-walled carbon nanotube sampling device to solve the above problems. Summary of the Invention

One end of the tension rope is fixedly connected to a float, and the other end of the tension rope is provided with a circular disk. The circular disk is slidably mounted in the receiving cavity, and a rubber pad is fixedly mounted on the bottom of the circular disk. The buoyancy mechanism is used to automatically take samples after the sampling bucket reaches the middle position of the sampling water area.

[0008] An adjustment mechanism is provided on sampling rod one and sampling rod two. The adjustment mechanism includes a movable block that is slidably disposed on the movable rod two. The movable rod two has several positioning holes. A locking pin is provided through the movable block and is locked in the positioning hole. The adjustment mechanism is used to adjust the sinking distance of the sampling bucket according to the depth of different water sampling areas.

[0009] Preferably, the bottom of the sampling bucket is connected to a one-way valve, which draws external water into the receiving cavity, and the outer surface of the sampling bucket is connected to a two-way valve, which discharges water from the receiving cavity of the sampling bucket.

[0010] Preferably, a counterweight is fixedly installed on the outer surface of the sampling bucket below the second one-way valve, and a movable rod is movably installed through the middle of the sampling bucket, with the bottom of the movable rod fixedly connected to the top of the circular disc.

[0011] Preferably, a fixing plate is provided above the second sampling rod, and a traction rope is fixedly provided on the fixing plate. The other end of the traction rope is fixedly connected to the top of the sampling bucket. Symmetrical blocks are fixedly and symmetrically provided at the ends of the second sampling rod. A fixed shaft is rotatably provided between the symmetrical blocks. A pulley is fixedly provided on the outer surface of the fixed shaft, and the traction rope passes through the pulley.

[0012] Preferably, the adjustment mechanism further includes a mounting cavity symmetrically arranged on the sampling rod one, a spring one fixedly arranged in the mounting cavity, a protrusion fixedly connected to the other end of the spring one, the outer surface of the protrusion sliding in the mounting cavity, and a plurality of locking holes symmetrically and equidistantly opened on the sampling rod two, the outer surface of the protrusion being locked in the locking holes.

[0013] Preferably, the movable block has a through hole, the inner wall of the through hole is slidably connected to the outer surface of the locking pin, and a fixing block is fixedly installed on the top of the movable block.

[0014] Preferably, the fixing block has a groove, and a connecting hole is provided through the groove, with the connecting hole and the through hole being concentrically arranged.

[0015] Preferably, the locking pin passes through the connecting hole, and an arc-shaped groove is provided on the locking pin, with an arc-shaped block rotatably disposed within the arc-shaped groove.

[0018] The beneficial effects of this application are:

[0019] This application provides a portable single-walled carbon nanotube sampling device, which uses two sampling rods, a first sampling rod and a second sampling rod, to be interlocked. The second sampling rod is a hollow sleeve, and the first sampling rod is a solid rod that can be inserted into it. When not in use, the two rods can be disassembled and stored to reduce their carrying length. Through the interlocking design of the sampling rods and the use of lightweight materials, the overall structure is compact and lightweight, making it suitable for mobile sampling in various scenarios such as fieldwork and laboratories.

[0020] This application provides a portable single-walled carbon nanotube sampling device. A circular disc is pulled upwards by a tension rope. Once the one-way valve opens, water samples from the middle of the water area flow into the receiving chamber, completing the sampling. After sampling, the operator pulls the traction rope upwards using a sampling rod. As the sampling bucket floats upwards, the buoy's pull decreases, and the one-way valve closes. The circular disc remains fixed in position under the constraint of the water sample within the receiving chamber, preventing water leakage.

[0021] This application provides a portable single-walled carbon nanotube sampling device. An adjustment mechanism adjusts the nesting length of two rods. Once the target length is reached, a spring resets and pushes a protrusion into the corresponding locking hole, locking the length. Because the locking holes are symmetrically and equidistantly distributed on the second sampling rod, the distance between each pair of adjacent holes corresponds to a fixed length adjustment, allowing for stepped adjustment of the sampling rod length. Operators can quickly and effectively collect samples by placing the sampling container in a relatively central part of the water from the shore.

[0022] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. These will be further described in detail below with reference to figures. Attached Figure Description

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0036] Reference Figures 1 to 9A portable single-walled carbon nanotube sampling device is disclosed, comprising: a sampling container 1, which is made of single-walled carbon nanotubes. Utilizing the high strength, lightweight, wear resistance, and chemical stability of single-walled carbon nanotubes, the device ensures structural strength while significantly reducing overall weight. A receiving cavity 2 is provided in the middle of the sampling container 1. Sampling rod 1 (first sampling rod 3) and sampling rod 2 (second sampling rod 4) are fitted onto the sampling container 1. Sampling rod 1 (first sampling rod 3) and sampling rod 2 (second sampling rod 4) are interlocked. Sampling rod 2 (second sampling rod 4) is a hollow sleeve, while sampling rod 1 (first sampling rod 3) is a solid rod that can be inserted into it. When not in use, the device can be disassembled and stored, reducing its length for carrying. Through the interlocking design of the sampling rods and the use of lightweight materials, the device achieves a compact and lightweight overall structure, suitable for mobile sampling in various scenarios such as fieldwork and laboratories.

[0037] Reference Figures 1 to 3 A portable single-walled carbon nanotube sampling device further includes: a buoyancy mechanism 5, which is disposed on the sampling bucket 1 and the sampling rod 4. The buoyancy mechanism 5 includes a tension rope 6 that is movably disposed through the sampling bucket 1. One end of the tension rope 6 is fixedly connected to a float 7, and the other end of the tension rope 6 is provided with a circular disk 12. The circular disk 12 is slidably disposed in the receiving cavity 2, and a rubber pad 13 is fixedly disposed at the bottom of the circular disk 12. The buoyancy mechanism 5 is used to automatically take samples after the sampling bucket 1 reaches the middle position of the sampling water area.

[0038] Furthermore, a one-way valve 8 is connected to the bottom of the sampling barrel 1, which draws external water into the receiving cavity 2. A one-way valve 9 is connected to the outer surface of the sampling barrel 1, which discharges water from the receiving cavity 2 of the sampling barrel 1. A counterweight 10 is fixedly installed on the outer surface of the sampling barrel 1 below the one-way valve 9. A movable rod 11 is movably installed through the middle of the sampling barrel 1, and the bottom of the movable rod 11 is fixedly connected to the top of the circular disc 12. A fixing plate 14 is installed above the sampling rod 4, and a traction rope 15 is fixedly installed on the fixing plate 14. The other end of the traction rope 15 is fixedly connected to the top of the sampling barrel 1. Symmetrical blocks 16 are fixedly and symmetrically installed at the end of the sampling rod 4. A fixed shaft 17 is rotatably installed between the symmetrical blocks 16. A pulley 18 is fixedly installed on the outer surface of the fixed shaft 17, and the traction rope 15 passes through the pulley 18.

[0039] In the above embodiment, before sampling, the circular disc 12 is at the bottom of the receiving cavity 2, and the rubber pad 13 at its bottom is tightly fitted to the one-way valve 8 at the bottom of the receiving cavity 2, forming a sealed state to prevent premature water ingress. At this time, the float 7 floats on the water surface due to buoyancy, and the tension rope 6 is in a slack state. The operator uses the connected sampling rod 3 and sampling rod 4 to put the sampling bucket 1 into the water and control its sinking. During the sinking process, the float 7 always floats on the water surface. As the depth of the sampling bucket 1 increases, the tension rope 6 is gradually straightened and generates an upward pull. However, since the circular disc 12 is initially located at the bottom of the receiving cavity 2 of the sampling bucket 1, the pull is insufficient to pull the circular disc 12. The rubber pad 13 maintains the seal on the one-way valve 8, ensuring that the sampling bucket 1 does not enter water before reaching the target depth. When the sampling bucket 1 sinks to the middle of the water (preset depth), the buoyancy of the float 7 and the pull transmitted through the tension rope 6 reach a critical value, which is sufficient to overcome the weight of the circular disc 12. Under the weight of the counterweight 10 and the buoyancy of the float 7, the circular disc 12 is pulled upward by the tension rope 6, opening the one-way valve 8, allowing the water sample from the middle of the water area to flow into the receiving chamber 2, completing the sampling. After sampling, the operator pulls the traction rope 15 upward using the sampling rod. During the upward movement of the sampling bucket 1, the tension of the float 7 decreases, the one-way valve 8 closes, and the circular disc 12 remains fixed in position under the constraint of the water sample in the receiving chamber 2, preventing water sample leakage. After retrieval, the one-way valve 9 can be opened by pressing the movable rod 11 on the top of the sampling bucket 1, allowing the sample water to be injected into the storage bottle, completing sample preservation.

[0040] Reference Figure 1 as well as Figures 3 to 9 A portable single-walled carbon nanotube sampling device further includes: an adjustment mechanism 19, which is disposed on sampling rod 1 3 and sampling rod 2 4. The adjustment mechanism 19 includes a movable block 20 slidably disposed on movable rod 2 11. Movable rod 2 11 has a plurality of positioning holes 25. A locking pin 30 is disposed through movable block 20 and is locked in the positioning hole 25. The adjustment mechanism 19 is used to adjust the sinking distance of sampling bucket 1 according to the depth of different water sampling areas.

[0041] The adjustment mechanism 19 also includes mounting cavities 21 symmetrically arranged on the sampling rod 3. A spring 22 is fixedly installed in the mounting cavity 21, and a protrusion 23 is fixedly connected to the other end of the spring 22. The outer surface of the protrusion 23 slides within the mounting cavity 21. Several locking holes 24 are symmetrically and equidistantly opened on the sampling rod 4, and the outer surface of the protrusion 23 is locked within the locking holes 24. A through hole 26 is opened through the movable block 20, and the inner wall of the through hole 26 is slidably connected to the outer surface of the locking pin 30. A fixing block 27 is fixedly installed on the top of the movable block 20. A groove 28 is opened on the fixing block 27, and a connecting hole 29 is opened through the groove 28. The connecting hole 29 is concentric with the through hole 26. The locking pin 30 passes through the connecting hole 29, and an arc-shaped groove 31 is opened on the locking pin 30. An arc-shaped block 34 is rotatably installed within the arc-shaped groove 31. A rotating shaft 32 is rotatably mounted within the groove 28. A rotating block 33 is fixedly mounted on the outer surface of the rotating shaft 32. The rotating block 33 is fixedly connected to the arc-shaped block 34. A limiting ring 35 is fixedly mounted within the groove 28. A second spring 36 is mounted within the limiting ring 35, with the end of the second spring 36 away from the limiting ring 35 abutting against the rotating block 33. In the above embodiment, the sampling rod 3 and the second sampling rod 4 form a nested telescopic structure. In the initial state, the first spring 22 in the mounting cavity 21 is in a naturally extended state, pushing the protrusion 23 outward, which then fits into the corresponding locking hole 24 of the second sampling rod 4, thus achieving relative fixation of the two rods. When the total length of the sampling rod needs to be adjusted, the operator pulls the end of sampling rod 3, causing the outer surfaces of the two protrusions 23 to slide into the mounting cavity 21 and be pressed into the cavity. Spring 22 is compressed, and protrusion 23 disengages from the current locking hole 24. At this time, sampling rod 4 can be pulled or pushed to adjust the nesting length of the two rods. Once the target length is reached, spring 22 resets and pushes protrusion 23 into the corresponding locking hole 24, completing the length lock. Because the locking holes 24 are symmetrically and equidistantly distributed on sampling rod 4, the distance between each pair of adjacent locking holes 24 corresponds to a fixed length adjustment amount, enabling a stepped adjustment of the sampling rod length. The operator can quickly and effectively sample the sample bucket 1 from the shore of the water area by placing it into a relatively central part of the water.

[0042] The specific details of this plan are as follows:

[0043] The operator checks the sealing status of the rubber pad 13 at the bottom of the circular disc 12 and the one-way valve 8, ensuring that the movable rod 11 is in the low position. Then, the operator pulls the end of the sampling rod 3, causing the outer surfaces of the two protrusions 23 to slide into the mounting cavity 21, whereupon they are pressed into the cavity. The spring 22 is compressed, and the protrusions 23 disengage from the current locking hole 24. At this point, the sampling rod 4 can be pulled or pushed to adjust the nesting length of the two rods. Once the target length is reached, the spring 22 resets and pushes the protrusions 23 into the corresponding locking holes 24, completing the length lock. Because the locking holes 24 are symmetrically and equidistantly distributed on the sampling rod 4, the distance between each pair of adjacent locking holes 24 corresponds to a fixed length adjustment amount, enabling a stepped adjustment of the sampling rod length. The operator can then quickly and effectively sample the sampling bucket 1 from the shore of the water area by placing it into a relatively central part of the water. Furthermore, when the sampling water is deep, pressing the rotating block 33 allows the movable block 20 to slide along the length of the sampling rod 4. Once the movable block 20 reaches the target position, it is secured by the locking pin 30. The locking pin 30 passes sequentially through the connecting hole 29 of the fixing block 27 and the through hole 26 of the movable block 20, finally inserting into the positioning hole 25 of the sampling rod 4, thus restricting the sliding of the movable block 20. To prevent the locking pin 30 from falling off due to vibration during sampling, the spring 36 continuously applies a pushing force to the rotating block 33. If readjustment is required, the operator simply presses the rotating block 33 into the groove 28 and compresses the spring 36. As the rotating block 33 drives the rotating shaft 32 to rotate, the arc-shaped block 34 lifts the locking pin 30 through the arc-shaped groove 31. After sliding the movable block 20 to the new position, the fixing steps are repeated, making the operation convenient and the locking secure. During the above process, the distance between sampling bucket 1 and sampling rod 2 4 gradually increases, allowing sampling bucket 1 to be placed in the middle of the water area, and the distance can be adjusted according to the depth of the water. Before sampling, the circular disc 12 is at the bottom of the receiving cavity 2, and the rubber pad 13 at its bottom is tightly fitted to the one-way valve 8 at the bottom of the receiving cavity 2, forming a seal to prevent premature water ingress. At this time, the float 7 floats on the water surface due to buoyancy, and the tension rope 6 is in a slack state. The operator uses the connected sampling rod 3 and sampling rod 2 4 to place sampling bucket 1 into the water area and control its sinking. During the sinking process, the float 7 always floats on the water surface. As the depth of sampling bucket 1 increases, the tension rope 6 is gradually straightened and generates an upward pull. However, since the circular disc 12 is initially located at the bottom of the receiving cavity 2 of sampling bucket 1, the pull is insufficient to pull the circular disc 12. The rubber pad 13 maintains the seal on the one-way valve 8, ensuring that sampling bucket 1 does not enter water before reaching the target depth. When the sampling container 1 sinks to the middle of the water area, the buoyancy of the float 7, transmitted through the tension rope 6, reaches a critical value, sufficient to overcome the weight of the circular disk 12. Through the weight of the counterweight 10 and the buoyancy of the float 7, the circular disk 12 is pulled upwards by the tension rope 6, the one-way valve 8 opens, and the water sample from the middle of the water area flows into the receiving chamber 2, completing the sampling.After sampling, the operator pulls the traction rope 15 upwards using the sampling rod. During the upward movement of the sampling bucket 1, the pull of the float 7 decreases, the one-way valve 8 closes, and the circular disc 12 remains fixed in position under the constraint of the water sample in the receiving cavity 2, preventing water sample leakage. After recovery, the one-way valve 9 can be opened by pressing the movable rod 11 on the top of the sampling bucket 1, allowing the sample water to be injected into the storage bottle, thus completing sample preservation.
