Description

Technical Field

[0001] This invention relates to the field of plateau wetland environmental sampling technology, and in particular to a multi-parameter collection and pretreatment device for plateau wetland soil and water quality. Background Technology

[0002] Plateau wetlands are important targets for ecosystem carbon sink surveys and assessments. In actual sampling operations in plateau wetlands, traditional sampling methods for water-covered wetlands often require personnel to directly enter the water body for operation. This is not only labor-intensive, but also poses health risks to the operators due to the strenuous physical activity in the oxygen-deficient environment of the plateau.

[0003] Existing methods for collecting soil from flooded wetlands (such as CN202311636111.7) typically involve inserting a PVC pipe into the bottom of the water, manually sucking out the water from the pipe, and then using a handheld soil drill to extract soil in layers. The entire process relies on manual operation, which is inefficient in aquatic environments and makes it difficult to conduct coordinated sampling of water bodies at the same station.

[0004] Although the sampling device for bottom sediment in high-altitude marsh wetlands has achieved mechanized pressing and lifting of the sampling tube, it is a single soil sampling device and cannot provide collaborative operation capabilities for water quality sampling at different water layers.

[0005] Therefore, it is necessary to provide a new device for multi-parameter acquisition and pretreatment of soil and water quality in plateau wetlands to solve the above-mentioned technical problems. Summary of the Invention

The conical bottom of the temporary storage cylinder, in conjunction with a drain valve, removes sediment, and the water sample automatically settles within the storage cylinder, constituting water-side pretreatment. On the soil side, the coordinated use of a second electric telescopic rod, push plate, sliding plate, storage cylinder, sealing plate, and sealing pad enables the orderly and closed transfer of soil samples from the collection cylinder to the storage cylinder. On the water-side, sampling is carried out in an orderly manner through a pumping pipe, ensuring that samples are not mixed or spilled throughout the entire process. Attached Figure Description

Figure 14 for Figure 13 A structural schematic diagram from another perspective is shown.

[0038] like Figures 1 to 3 As shown, a multi-parameter collection and pretreatment device for soil and water quality in plateau wetlands includes a mobile mechanism 1, two mounting frames 2, a soil collection mechanism 3, and a water quality collection mechanism 4. The device provided by this invention is mainly used in wetlands with high water content, especially for collecting and pretreating soil and water quality in water-covered wetlands, to solve the problem of inconvenient direct access for personnel in existing technologies.

[0039] like Figure 4 , Figure 5 As shown, the moving mechanism 1 includes two symmetrically arranged support plates 11, with a single float 12 fixedly installed between the two support plates 11. Four symmetrically arranged moving wheels 13 are located below the float 12, and rubber pads 14 are fixedly installed on the outer sides of the moving wheels 13. Four symmetrically fixed moving motors 15 are mounted on the upper support plate 11, and the moving motors 15 are connected to the corresponding moving wheels 13 via a transmission mechanism 16.

[0040] The mobile wheel 13 includes a mounting plate fixedly installed on the support plate 11 located below. A mobile frame is rotatably mounted on the mounting plate. A circular ring is fixedly installed on the outer side of the mobile frame, and multiple convex blocks are fixedly installed on the outer side of the circular ring. The convex blocks provide grip on land and shallow water soft mud substrates. At the same time, the convex blocks can also serve as the propulsion for the entire device in water. The float plate 12 provides buoyancy. The two work together to realize the amphibious movement of the device.

[0041] like Figures 1 to 3 As shown, two mounting brackets 2 are symmetrically fixedly mounted on the top of the moving mechanism 1. Figure 6 , Figure 7 As shown, the mounting frame 2 includes a vertical plate 21 fixedly mounted on the top of the moving mechanism 1. Two horizontal plates 22 are fixedly mounted on one side of the vertical plate 21. Two reinforcing frames 23 are symmetrically fixedly mounted at one end on the side of the vertical plate 21 away from the horizontal plates 22. The other ends of the reinforcing frames 23 are fixedly mounted on the top of the moving mechanism 1. A drive motor 24 is fixedly mounted on the top of the lower horizontal plate 22. A first gear 25 is fixedly mounted on the output shaft of the drive motor 24. The same internally threaded cylinder 26 is rotatably mounted on both horizontal plates 22. A second gear 27 is fixedly sleeved on the outer side of the internally threaded cylinder 26. The first gear 25 meshes with the second gear 27. The drive motor 24 drives the first gear 25 to rotate, causing the second gear 27 and the internally threaded cylinder 26 to rotate synchronously.

[0042] like Figure 6 , Figure 7 As shown, the soil collection mechanism 3 is mounted on one of the mounting brackets 2. The soil collection mechanism 3 includes a threaded post 301, which is installed inside an internal threaded cylinder 26. When the internal threaded cylinder 26 rotates, the threaded post 301 moves up and down axially. A soil collection cylinder 302 is fixedly mounted at the bottom end of the threaded post 301, as shown. Figure 8 As shown, the top of the soil collection cylinder 302 has multiple through holes 303. An installation ring 304 is fixedly installed on the outside of the threaded post 301. The top end of the spring 305 is fixedly installed on the bottom of the installation ring 304. A pressure ring 306, which is slidably sleeved on the outside of the threaded post 301, is fixedly installed on the bottom of the spring 305. Multiple sealing blocks 311 are fixedly installed on the bottom of the pressure ring 306. The sealing blocks 311 are adapted to the through holes 303.

[0043] like Figure 7 As shown, multiple connecting rods 307 are fixedly installed on the top of the pressure ring 306. The connecting rods 307 pass through the horizontal plate 22 and are slidably connected to the horizontal plate 22. An mounting plate 308 is fixedly installed on the top of the connecting rods 307, and the connecting rods 307 pass through the mounting plate 308 and are slidably connected to the mounting plate 308. A first electric telescopic rod 309 is fixedly installed on the top of the first electric telescopic rod 309, and a connecting plate 310 is fixedly installed on the top of the first electric telescopic rod 309. All connecting rods 307 are fixedly connected to the bottom of the connecting plate 310. When the first electric telescopic rod 309 extends or retracts, the pressure ring 306 is driven to move axially relative to the threaded post 301 through the connecting plate 310 and the connecting rods 307, thereby controlling the sealing block 311 to seal or disengage from the through hole 303.

[0044] like Figure 9 , Figure 10 As shown, the soil collection mechanism 3 also includes a sample storage mechanism. The sample storage mechanism includes two symmetrically fixedly mounted second electric telescopic rods 312 (the second electric telescopic rods 312 are fixedly mounted on corresponding bases of the moving mechanism 1 or the mounting frame 2). A single push plate 313 is fixedly mounted on the output shaft of the two second electric telescopic rods 312. A sliding plate 314 is fixedly mounted on the push plate 313, and a storage cylinder 315 is fixedly mounted on the top of the sliding plate 314. The storage cylinder 315 is compatible with the soil collection cylinder 302. A sealing plate 316 is fixedly mounted on the top of the moving mechanism 1, and a sealing pad 317 is fixedly mounted on the bottom of the sealing plate 316. The top of the storage cylinder 315 is in contact with the sealing plate 316.

[0045] like Figures 11 to 14As shown, the water quality collection mechanism 4 is mounted on another mounting bracket 2. The water quality collection mechanism 4 includes a threaded cylinder 41 threaded inside an inner threaded cylinder 26, with both ends of the threaded cylinder 41 extending outside the inner threaded cylinder 26. A limiting groove is formed on the outer side of the threaded cylinder 41, and a limiting block is fixedly installed on one of the horizontal plates 22 corresponding to the threaded cylinder 41. The limiting block is slidably installed in the limiting groove to prevent the threaded cylinder 41 from rotating with the inner threaded cylinder 26, thereby ensuring the normal operation of the threaded cylinder 41. A fixing rod 42 is fixedly installed at the bottom end of the threaded cylinder 41, and multiple collection heads 44 are fixedly installed on the fixing rod 42. A filter screen 45 is fixedly installed on the collection head 44, and one end of a connecting pipe 43 is connected to the collection head 44. The connecting pipe 43 passes through the threaded cylinder 41 and is fixedly connected to the threaded cylinder 41. The other end of the connecting pipe 43 is connected to a temporary storage cylinder 46. Multiple temporary storage cylinders 46 are connected to the same water pump 47. Both the water pump 47 and the temporary storage cylinders 46 are fixedly connected to the moving mechanism 1.

[0046] like Figure 13 , Figure 14 As shown, the bottom of the temporary storage cylinder 46 is tapered, and a drain valve 48 is fixedly installed at the bottom of the temporary storage cylinder 46. A water pumping pipe 49 is provided at the top of the temporary storage cylinder 46, and a sealing cap is provided on the water pumping pipe 49.

[0047] It should be noted that a limiting groove is provided on the outer side of the threaded cylinder 41, and a limiting block is fixedly installed on one of the horizontal plates 22 corresponding to the threaded cylinder 41. The limiting block is slidably installed in the limiting groove to prevent the threaded cylinder 41 from rotating together with the inner threaded cylinder 26, thereby ensuring the normal operation of the threaded cylinder 41.

[0048] The working principle of the plateau wetland soil-water quality multi-parameter acquisition and pretreatment device provided by this invention is as follows:

[0049] Mobile Positioning: Since the device provided by the present invention is mainly used in wetlands with high water content, especially wetlands covered by water, by starting the mobile motor 15, the mobile motor 15 drives the mobile wheel 13 to rotate through the transmission mechanism 16. The rubber pad 14 and the convex block provide grip, and the float 12 provides buoyancy. The device moves to the target sampling station on the water body, shallow beach, and soft mud matrix of the plateau wetland, thereby solving the problem that it is inconvenient for personnel to directly enter in the prior art.

[0050] Soil collection: When collecting underwater soil from the wetland, the corresponding drive motor 24 is activated to rotate the inner threaded cylinder 26, thereby causing the threaded column 301 to move downward. When the soil collection cylinder 302 comes into contact with the underwater soil, as the threaded column 301 continues to descend, the soil collection cylinder 302 is inserted into the soil. At this time, the air or water inside the soil collection cylinder 302 is discharged through the through hole 303 until the soil collection cylinder 302 is inserted to the required depth. Then, the first electric telescopic rod 309 is activated. The first electric telescopic rod 309 moves downward through the connecting plate 310, the connecting rod 307 and the pressure ring 306, thereby causing the sealing block 311 to move downward into the through hole, thus completing the sealing of the through hole 303 (by sealing the through hole 303, the soil can be prevented from moving out of the soil collection cylinder 302 by using the pressure difference principle). At this time, the drive motor 24 can be activated in reverse to remove the threaded column 301 together with the soil collection cylinder 302 and the sampled soil inside the soil collection cylinder 302 and remove them from the water surface. In order to better achieve the soil sampling work of the soil sampling tube 302, the entire device can be moved by starting the moving motor 15, thereby removing the soil around the soil sampling tube 302. Then, the moving motor 15 is started in reverse, so that when the soil sampling tube 302 is moved upward, the pressure difference can be better utilized to reduce the soil sample falling off the soil sampling tube 302.

[0051] Soil sample transfer: After the soil collection tube 302 collects soil and rises to its highest point, the second electric telescopic rod 312 is activated to drive the push plate 313 and sliding plate 314 to move, so that the storage tube 315 moves out of the sealing plate 316 and finally the storage tube 315 is directly below the soil collection tube 302. Then the first electric telescopic rod 309 is activated in the opposite direction to move the sealing block 311 out of the through hole 303. At this time, the pressure at the top and bottom of the soil in the soil collection tube 302 is almost the same. The collected soil sample falls automatically into the storage tube 315 under the action of gravity. Then the second electric telescopic rod 312 is activated in the opposite direction to make the storage tube 315 re-contact with the sealing gasket 317, thus completing the sealed storage of the sample.

[0052] Water sampling: When sampling water, the corresponding drive motor 24 is started to rotate the internal threaded cylinder 26. Since the limiting groove on the threaded cylinder 41 cooperates with the limiting block on the horizontal plate 22, the threaded cylinder 41 does not rotate circumferentially but only moves downward along the axis. The threaded cylinder 41 drives the fixed rod 42 to move downward, and the fixed rod 42 drives multiple sampling heads 44 to move downward until the sampling heads reach the appropriate water depth. The water pump 47 is started, and the water pump 47 pumps the water in the water layer where the sampling head 44 is located into the corresponding temporary storage cylinder 46 through the connecting pipe 43. When the appropriate amount of water is pumped into the temporary storage cylinder 46, the water pump 47 is turned off, and the water sample automatically settles in the temporary storage cylinder 46. Thus, when the entire device is moved to the shore, the water sample in the upper layer of the temporary storage cylinder 46 can be taken out through the water pumping pipe 49, thereby realizing the pretreatment of the water sample.

[0053] Water quality discharge: When it is necessary to discharge the sediment or residual water in the temporary storage cylinder 46, open the drain valve 48 at the bottom of the temporary storage cylinder 46. The conical bottom facilitates the collection of sediment and discharge from the drain valve 48, avoiding cross-contamination between different batches of water samples.

[0054] Compared with related technologies, the multi-parameter acquisition and pretreatment device for soil and water quality in plateau wetlands provided by this invention has the following beneficial effects:

[0055] This invention provides a multi-parameter collection and pretreatment device for soil and water quality in plateau wetlands. Utilizing the amphibious mobility of the mobile mechanism 1, the device can move autonomously to sampling stations in water-covered wetlands, avoiding direct entry of personnel into the water. A floating plate 12 provides buoyancy, while wheels 13 and convex blocks provide traction, allowing the device to move freely across water bodies, shallows, and soft mud substrates in plateau wetlands to reach designated sampling stations. Two symmetrically arranged mounting frames 2 allow the soil collection mechanism 3 and water quality collection mechanism 4 to work collaboratively at the same station, ensuring strict spatial correspondence of the collected soil and water samples. The through-hole 303 of the soil collection cylinder 302 cooperates with the sealing block 311 during collection... After collection, the system automatically seals, using the pressure difference principle to prevent soil samples from falling off during the lifting process, thus constituting soil-side pretreatment. Multiple collection heads 44 collect water samples at different water layers, and the filter screen 45 performs preliminary filtration. The conical bottom of the temporary storage cylinder 46 works in conjunction with the drain valve 48 to remove sediment, and the water sample automatically settles in the temporary storage cylinder 46, constituting water-side pretreatment. On the soil side, the coordinated use of the second electric telescopic rod 312, push plate 313, sliding plate 314, storage cylinder 315, sealing plate 316, and sealing pad 317 enables the orderly and closed transfer of soil samples from the collection cylinder to the storage cylinder. On the water-side, the pumping pipe 49 takes samples in an orderly manner, ensuring that samples are not mixed or spilled throughout the entire process.
