Description

Technical Field

[0001] This invention relates to the field of experimental equipment for aquatic ecological environment, and in particular to an experimental device for sediment disturbance. Background Technology

[0002] In daily life, pollutants, after entering rivers, lakes, and seas, undergo mechanical migration with the flow of water. During horizontal migration, pollutants can gradually flocculate, settle, and accumulate, resulting in a higher pollutant content in sediments than in the corresponding water phase, and exhibiting a strong distribution pattern. Therefore, sediments are an excellent medium for studying the migration and distribution characteristics of pollutants in rivers, lakes, and seas. Among these, the vertical migration behavior of pollutants at the sediment-water interface is an important component of the main behavior of pollutants in the aquatic environment. At the same time, the release of pollutants caused by vertical migration is a fundamental scientific issue in the control of endogenous pollution in aquatic environmental systems. Hydrodynamic conditions are one of the key factors affecting the release of pollutants from sediments. Therefore, studying the impact of hydrodynamic conditions on the release of pollutants from sediments is of great significance.

[0003] In existing technologies, various sediment disturbance experimental devices have been proposed to study the impact of hydrodynamic conditions on the release of pollutants from sediments. However, these devices have the following problems: 1. When water is added, the water flow impacts the sediment sample, causing significant disturbance to the sample surface. This prevents the device from accurately reflecting the state of the sediment, leading to inaccurate experimental results. Furthermore, subsequent operations can only be performed after the water body has stabilized, resulting in long experimental times and low efficiency. 2. In the experiment, the distance between the upper surface of the sediment sample and the bottom of the stirring rod is fixed. However, due to the high heterogeneity of sediments, the length of the columnar sediment samples collected each time is inconsistent. Therefore, the height of the stirring rod needs to be adjusted according to the length of the columnar sediment sample, making the experimental operation cumbersome and inefficient. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an easy-to-operate experimental apparatus for sediment disturbance, which not only helps to improve the accuracy of experimental results but also helps to improve experimental efficiency.

[0005] An experimental apparatus for sediment disturbance according to an embodiment of the present invention includes: a base plate on which a mounting post is vertically disposed, and a support portion at the upper part of the mounting post; a gate assembly including a first connecting plate, a second connecting plate, a sealing gate, and a limiting member; the first connecting plate having a first mounting through hole, the upper end of the mounting post passing through the first mounting through hole, the first connecting plate overlapping the support portion; the second connecting plate being located above the first connecting plate, the second connecting plate having a second mounting through hole, the upper end of the mounting post passing through the second mounting through hole; the sealing gate being slidably sandwiched between the first connecting plate and the second connecting plate, one end of the sealing gate extending from between the first connecting plate and the second connecting plate; the limiting member being detachably disposed on the upper part of the mounting post and abutting against the top of the second connecting plate; and a sample tube having a transparent structure, with both the upper and lower ends of the sample tube being open structures, and the first connecting plate having a first clearance through hole. The inner diameter of the first clearance through-hole is equal to the outer diameter of the sample tube. The upper end of the sample tube is embedded in the first clearance through-hole and fixedly connected to the first connecting plate. The sealing gate plate is provided with a gate hole, the diameter of which is equal to the inner diameter of the sample tube. A piston is vertically mounted inside the sample tube and is used to support the deposit sample. A height adjustment structure is provided between the piston and the substrate. A disturbance tube is a transparent structure with open upper and lower ends. The second connecting plate is provided with a second clearance through-hole located directly above the first clearance through-hole. The inner diameter of the second clearance through-hole is equal to the outer diameter of the disturbance tube. The lower end of the disturbance tube is embedded in the second clearance through-hole and fixedly connected to the second connecting plate. The inner diameter of the disturbance tube is equal to the diameter of the gate hole. A disturbance assembly includes a bracket, a motor, and a stirring paddle. The motor is mounted on the bracket, and the stirring paddle is connected to the output end of the motor and extends into the disturbance tube.

[0006] The sediment disturbance experimental apparatus according to an embodiment of the present invention has at least the following beneficial effects: In use, the sealing gate is slidable, and after the gate opening and the second clearance through-hole are completely misaligned, the water required for the experiment is injected into the disturbance tube. Simultaneously, the height of the piston is adjusted by the height adjustment structure so that the top of the columnar sediment sample is flush with the upper end face of the sample tube. After the water injected into the disturbance tube stabilizes, the sealing gate is slidable so that the gate opening and the second clearance through-hole slowly overlap, thereby connecting the disturbance tube to the sample tube and allowing the water in the disturbance tube to slowly contact the columnar sediment sample in the sample tube. This design helps reduce disturbance to columnar sediment samples by water. The distance from the bottom of the stirring paddle to the top of the sample tube is a fixed value, which can be pre-configured to the required distance for the experiment. During the experiment, there is no need to repeatedly adjust the position of the stirring paddle; simply adjusting the height of the piston via the height adjustment structure to align the top of the columnar sediment sample with the top of the sample tube satisfies the distance requirement between the top of the columnar sediment sample and the bottom of the stirring paddle. This sediment disturbance experimental device is easy to operate, which not only improves the accuracy of experimental results but also increases experimental efficiency.

[0030] Reference Figure 1 and Figure 2 According to an embodiment of the present invention, a sediment disturbance experimental apparatus includes a substrate 100, a gate assembly 200, a sample tube 300, a piston 400, a disturbance tube 500, and a disturbance assembly 600.

[0031] A mounting post 110 is vertically provided on the base plate 100. A support portion 111 is provided on the upper part of the mounting post 110. The gate assembly 200 includes a first connecting plate 210, a second connecting plate 220, a sealing gate 230, and a limiting member 240. A first mounting through hole is provided on the first connecting plate 210 corresponding to the mounting post 110. The upper end of the mounting post 110 passes through the first mounting through hole. The first connecting plate 210 overlaps the support portion 111. The second connecting plate 220 is located above the first connecting plate 210. A second mounting through hole is provided on the second connecting plate 220 corresponding to the mounting post 110. The upper end of the mounting post 110 passes through the second connecting plate 220. The second mounting through hole allows the sealing gate 230 to be slidably sandwiched between the first connecting plate 210 and the second connecting plate 220. One end of the sealing gate 230 extends from between the first connecting plate 210 and the second connecting plate 220. The limiting member 240 is detachably disposed on the upper part of the mounting post 110 and abuts against the top of the second connecting plate 220. The sample tube 300 is transparent, with both its upper and lower ends open. The first connecting plate 210 has a first clearance through hole 211 corresponding to the opening at the upper end of the sample tube 300. The inner diameter of the first clearance through hole 211 is equal to the outer diameter of the sample tube 300. The upper end of the sample tube 300 is embedded in the first clearance through hole 211 and fixedly connected to the first connecting plate 210. A gate hole 231 is provided on the sealing gate plate 230 corresponding to the opening at the lower end of the sample tube 300. The diameter of the gate hole 231 is equal to the inner diameter of the sample tube 300. The piston 400 is vertically and vertically disposed within the sample tube 300 and is used to support the sediment sample. A height adjustment structure is provided between the piston 400 and the substrate 100, which can adjust the height of the piston 400. The disturbance tube 500 is a transparent structure, with both its upper and lower ends open. A corresponding disturbance hole is provided on the second connecting plate 220. The lower end of the moving tube 500 has a second clearance through hole 221. The second clearance through hole 221 is located directly above the first clearance through hole 211. The inner diameter of the second clearance through hole 221 is equal to the outer diameter of the disturbance tube 500. The lower end of the disturbance tube 500 is embedded in the second clearance through hole 221 and fixedly connected to the second connecting plate 220. The inner diameter of the disturbance tube 500 is equal to the diameter of the gate hole 231. The disturbance component 600 includes a bracket 610, a motor 620 and a stirring paddle 630. The motor 620 is mounted on the bracket 610. The stirring paddle 630 is connected to the output end of the motor 620 and extends into the disturbance tube 500.

[0032] In use, the sealing gate 230 is slid to allow the gate hole 231 to fully align with the second clearance through hole 221 before injecting the required water into the disturbance tube 500. Simultaneously, the height of the piston 400 is adjusted using the height adjustment structure to align the top of the columnar sediment sample with the upper surface of the sample tube 300. Once the water in the disturbance tube 500 has stabilized, the sealing gate 230 is slid to allow the gate hole 231 to slowly overlap with the second clearance through hole 221, thus connecting the disturbance tube 500 with the sample tube 300 and allowing the water in the disturbance tube 500 to slowly contact the columnar sediment sample in the sample tube 300. This helps to reduce the impact of the water on the columnar sediment. The sediment sample disturbance device uses a fixed distance between the bottom of the stirring paddle 630 and the upper surface of the sample tube 300. This distance can be pre-configured to meet the experimental requirements. During the experiment, there is no need to repeatedly adjust the position of the stirring paddle 630. The height of the piston 400 can be adjusted by adjusting the height adjustment structure to make the top of the columnar sediment sample flush with the upper surface of the sample tube 300, thus meeting the distance requirement between the top of the columnar sediment sample and the bottom of the stirring paddle 630. The above-mentioned sediment disturbance experimental device is easy to operate, which not only helps to improve the accuracy of the experimental results but also improves the experimental efficiency.

[0033] It should be noted that in some embodiments, the mounting post 110 is a screw, and correspondingly, the support part 111 and the limiting member 240 are nuts. Of course, the support part can also be a block structure integrally formed on the mounting post, and the limiting member can also be a snap ring. Correspondingly, the mounting post is provided with a snap groove for snapping the snap ring, which is not limited here.

[0034] It should be noted that in some embodiments, the first connecting plate 210, the second connecting plate 220, and the sealing gate 230 are all glass plates, and the sample tube 300 and the disturbance tube 500 are both glass tubes. The sample tube 300 is glued to the first connecting plate 210, and the disturbance tube 500 is glued to the second connecting plate 220. Of course, the first connecting plate, the second connecting plate, and the sealing gate can also be plastic plates, and the sample tube and the disturbance tube can also be plastic tubes. The sample tube is glued to the first connecting plate or fused to the first connecting plate, and the disturbance tube is glued to the second connecting plate or fused to the second connecting plate. No limitation is made here.

[0035] It should be noted that in some embodiments, the first connecting plate 210, the second connecting plate 220, the sample tube 300, and the disturbance tube 500 are all consumables. Before using the above-mentioned sediment disturbance experimental device, the first connecting plate 210, the second connecting plate 220, the sample tube 300, and the disturbance tube 500 used in the previous experiment need to be disassembled, and then the unused first connecting plate 210, the second connecting plate 220, the sample tube 300, and the disturbance tube 500 need to be installed. Regarding the sample tube 300, before installation, it is necessary to first use the sample tube 300 to take a sample and support the columnar sediment sample in the sample tube 300 through the piston 400. Then, the upper end of the sample tube 300 is embedded in the first clearance through hole 211 and the sample tube 300 is fixedly connected to the first connecting plate 210.

[0036] Reference Figure 1 In some embodiments, the height adjustment structure includes a first counterweight 710, a first support column 720, a second support column 730, and a handwheel 740. An operating gap exists between the lower end face of the sample tube 300 and the substrate 100. The first counterweight 710 is placed on the substrate 100 and located directly below the sample tube 300. The lower end of the first support column 720 is fixedly connected to the first counterweight 710. The second support column 730 is a hollow tubular structure, with its upper end fixedly connected to the bottom of the piston 400. The first support column 720 is inserted into the second support column 730 and threadedly connected to it. The handwheel 740 is fixedly mounted on the second support column 730 and used to drive the second support column 730 to rotate. Specifically, the first counterweight 710 prevents the first support column 720 from rotating along with the second support column 730. The operating gap is the operating space for manually adjusting the height of the piston 400. In use, the operator can adjust the height of the piston 400 by inserting their hand into the sample tube 300 through the operating gap between the lower end face of the sample tube 300 and the substrate 100 and turning the handwheel 740.

[0037] It should be noted that in some embodiments, the height adjustment structure may also be a cylinder or an electric push rod, which is not limited here.

[0038] Reference Figure 1 In some embodiments, the sealing gate 230 is provided with a handle 232 at one end extending between the first connecting plate 210 and the second connecting plate 220, so that the operator can drive the sealing gate 230 to slide.

[0039] It should be noted that in some embodiments, a guide mechanism is provided between the sealing gate 230 and the first connecting plate 210 and / or the second connecting plate 220 to limit the sliding trajectory of the sealing gate 230, which helps to improve the stability of the sealing gate 230 during operation.

[0040] Reference Figure 2 and Figure 3 In some embodiments, the guiding mechanism includes a first protrusion 233 and a second protrusion 234. The first protrusion 233 is located on the side edge of the bottom of the sealing gate 230, and is elongated along the length of the sealing gate 230. The top of the first connecting plate 210 is provided with a first groove 212 corresponding to the first protrusion 233, and the first protrusion 233 is slidably embedded in the first groove 212. The second protrusion 234 is located on the side edge of the top of the sealing gate 230, and is elongated along the length of the sealing gate 230. The sealing gate 230 is positioned along its length, and the bottom of the second connecting plate 220 is provided with a second groove 222 corresponding to the second protrusion 234. The second protrusion 234 is slidably embedded in the second groove 222. Its structure is simple and easy to implement. However, the contact area between the sealing gate 230 and the first connecting plate 210 and the second connecting plate 220 along the width direction is small, making it easy for water to seep in. The cooperation between the first protrusion 233 and the first groove 212, as well as the cooperation between the second protrusion 234 and the second groove 222, helps to prevent water seepage.

[0041] It should be noted that in some embodiments, the first protrusion is located on the top of the first connecting plate, and the second protrusion is located on the bottom of the second connecting plate. Correspondingly, the first sliding groove is located on the bottom of the sealing gate, and the second sliding groove is located on the top of the sealing gate. This is not limited here.

[0042] Reference Figure 4 and Figure 5 In some embodiments, a rubber gasket 800 is fixedly provided on the upper end face of the sample tube 300 and the lower end face of the disturbance tube 500. The rubber gasket 800 has a sealing effect and helps to prevent water leakage.

[0043] It should be noted that in some embodiments, a baffle assembly for generating turbulence is detachably provided inside the disturbance tube 500. The baffle assembly can prevent the water in the disturbance tube 500 from forming a rotating water column as the agitator 630 rotates, thereby facilitating the simulation of turbulence in rivers, lakes and seas. The baffle assembly is configured as a detachable structure, and different baffle assemblies can be replaced according to different experimental requirements to simulate different turbulence.

[0044] Reference Figure 1In some embodiments, the baffle assembly includes a first fixing ring 910, a second fixing ring 920, and a plurality of baffle bodies 930. The upper end of the baffle body 930 is fixedly connected to the first fixing ring 910, and the lower end of the baffle body 930 is fixedly connected to the second fixing ring 920. The plurality of baffle bodies 930 are spaced apart. The first fixing ring 910 and the second fixing ring 920 are both embedded in the disturbance tube 500. The baffle assembly is fixed in the disturbance tube 500 by the friction between the first fixing ring 910 and the inner wall of the disturbance tube 500 and the friction between the second fixing ring 920 and the inner wall of the disturbance tube 500. Specifically, the outer diameter of the first fixing ring 910 is equal to or slightly smaller than the inner diameter of the disturbance tube 500, the outer diameter of the second fixing ring 920 is equal to the outer diameter of the first fixing ring 910, and the angle between the baffle and the tube wall of the disturbance tube 500 is an acute angle.

[0045] Reference Figure 1 In some embodiments, a second counterweight 640 is provided at the bottom of the bracket 610, which helps to improve the stability of the bracket 610 during operation.

[0046] Reference Figure 1 In some embodiments, the support 610 includes a vertical rod 611 and a horizontal rod 612, with the horizontal rod 612 mounted on the vertical rod 611 and the motor 620 mounted on the horizontal rod 612. A position adjustment structure is provided between the vertical rod 611 and the horizontal rod 612. The position adjustment structure can adjust the position of the horizontal rod 612 so that the operator can adjust the distance from the bottom of the stirring paddle 630 to the upper end face of the sample tube 300 according to the experimental requirements. The position adjustment structure is a well-known technology in the art and will not be described in detail here.
