Description

Technical Field

[0001] This invention belongs to the technical field of permeability measuring devices, and particularly relates to a device for measuring the influence of soil animal pores on soil infiltration performance. Background Technology

[0002] Traditionally, there has been limited research on soil infiltration performance through soil animal (ant, earthworm, rodent, etc.) pores. Conventional field experimental setups mainly utilize the double-ring method, which involves artificially injecting water into the rings and measuring the amount of water injected at the same time or at different times with the same amount of water to compare the differences in soil infiltration process, saturated hydraulic conductivity, initial infiltration, and steady-state infiltration rates between soil animal pores and those without.

[0003] However, soil animal pores have high permeability, and using conventional water replenishment methods with water from jars requires frequent water replenishment and manual timing. Furthermore, existing experimental setups cannot observe the morphology and infiltration characteristics of the soil animal pores after infiltration.

[0004] Therefore, an apparatus for determining the effect of soil animal pores on soil infiltration performance is provided to solve the above-mentioned problems. Summary of the Invention

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Reference Figures 1-7 The present invention provides an apparatus for measuring the effect of soil animal pores on soil infiltration performance, comprising: a water storage tank 1, arranged above an inner ring 2 and an outer ring 3, connected to the inner ring 2 through a first pipe 4, and connected between the inner ring 2 and the outer ring 3 through a second pipe 5.

[0040] The water storage tank 1 replaces the conventional flask structure, has a larger water storage capacity, and does not require frequent water replenishment. A water inlet is located on the top of the water storage tank 1 for replenishing the water inside.

[0041] The inner ring 2 and outer ring 3 are the relevant structures in the double-ring method experiment. During the infiltration experiment, a 1m × 1m test pit with a depth of 0.5m is first dug on the ground surface. The double-ring permeameter is 30cm high, with an outer ring inner diameter of 0.3m and an inner ring diameter of 0.15m. The two rings are placed concentrically, and the two rings are slowly and forcefully pressed into the soil, for example, inserting them 5cm into the soil layer. If the permeability is very good, 3-4cm of gravel should be laid down when releasing water to prevent damage to the surface soil.

[0042] The control opening and closing unit 6 is connected to the first pipeline 4 and the second pipeline 5 respectively, and is configured to control the opening and closing of the first pipeline 4 and the second pipeline 5.

[0043] Specifically, the control opening and closing unit 6 is used to control the opening and closing of the first pipeline 4 and the second pipeline 5.

[0044] The dyeing unit 7 is connected to the water storage tank 1, and its discharge end is connected to the first pipeline 4 so that the dye in the dyeing unit 7 is mixed with the liquid in the first pipeline 4.

[0045] Specifically, the dyeing unit 7 is connected to the first pipeline 4. After the dye is mixed with the water in the first pipeline 4, the product has a color that is different from that of transparent water. The product is sent into the inner ring 2, which can visually display the morphology and infiltration characteristics of the soil animal pores after infiltration.

[0046] The dye can be a solid particle or a liquid, preferably a dye with good solubility and dyeing properties.

[0047] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 It also includes a water level control unit 8, which is connected to the first pipe 4 and the second pipe 5 and is configured to control the water level in the inner ring 2 and between the inner ring 2 and the outer ring 3.

[0048] Specifically, in the double-ring method experiment, it is necessary to control the water level in the inner ring 2 and the water level between the inner ring 2 and the outer ring 3 to maintain them at similar levels. The conventional method of maintenance is mostly to observe manually and add water accordingly based on the observed structure. However, the above method is not only cumbersome but also has a large error. Therefore, a water level control unit 8 is set up to control the water level in the inner ring 2 and between the inner ring 2 and the outer ring 3.

[0049] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 The water level control unit 8 includes: a first liquid level sensor 801, which is disposed above the inner ring 2 and configured to acquire the liquid level height within the inner ring 2; the first liquid level sensor 801 is connected to a first water level control valve 802 via a first control console; the first water level control valve 802 is connected to the outlet end of the first pipeline 4; and a second liquid level sensor 803, which is disposed above the space between the inner ring 2 and the outer ring 3 and configured to acquire the liquid level height between the inner ring 2 and the outer ring 3; the second liquid level sensor 803 is connected to a second water level control valve 804 via a second control console; the second water level control valve 804 is connected to the outlet end of the second pipeline 5.

[0050] Specifically, the first liquid level sensor 801 and the second liquid level sensor 803 are fixed on the mounting bracket 21, and their detection ends correspond to the water body in the inner ring and the water body between the inner ring and the outer ring. The first liquid level sensor 801 and the second liquid level sensor 803 respectively detect the corresponding liquid level height, and feed the liquid level height data back to the first control console and the second control console respectively through data lines. The first control console and the second control console analyze the data, determine the liquid level height, and control the opening and closing of the first water level control valve 802 and the second water level control valve 804.

[0051] In one embodiment of the present invention, preset liquid level height data are respectively provided in the first control console and the second control console, and the preset liquid level height data are equal. The liquid level height data monitored by the first liquid level sensor 801 and the second liquid level sensor 803 are fed back to the first control console and the second control console. By comparing the fed-back liquid level height data with the preset liquid level height data, if the fed-back liquid level height data is higher than the preset liquid level height data, then the first water level control valve 802 and the second water level control valve 804 are closed accordingly; if the fed-back liquid level height data is lower than the preset liquid level height data, then the first water level control valve 802 and the second water level control valve 804 are opened accordingly.

[0052] The first liquid level sensor 801 and the second liquid level sensor 803 are either laser liquid level sensors or pressure liquid level sensors. This embodiment uses a laser liquid level sensor as an example.

[0053] In this embodiment, refer to Figure 4 , Figure 5 It also includes: a mixing box 9, connected to the first pipeline 4, which is divided into an upper chamber and a lower chamber by a partition 10, with a water passage hole 11 on the partition 10, and the discharge end of the dyeing unit 7 is connected to the side wall of the lower chamber; a float plug 12, which is connected to the lower chamber by a connecting rope 13 and is configured to block the water passage hole 11; and a plug 14, which is fixed to the connecting rope 13 and is configured to block the discharge end of the dyeing unit 7.

[0054] Specifically, the mixing tank 9 is connected to the water storage tank 1 via the first pipe 4. Therefore, clean water first enters the upper chamber and flows into the lower chamber through the water passage 11. Since a float plug 12 is installed in the lower chamber, the float plug 12 blocks the water passage 11 after the water in the lower chamber is stored to a certain amount, thus maintaining the water volume in the lower chamber. Furthermore, the block 14 blocks the discharge end of the dyeing unit 7 when the float plug 12 blocks the water passage 11.

[0055] In some cases, to ensure that the water levels within the inner ring 2 and between the inner ring 2 and the outer ring 3 are similar, the first water level control valve 802 may be closed. When closed, to prevent dye from continuously mixing with clean water and wasting dye, a mixing tank 9 is provided, containing a float plug 12 and a block 14. If the first water level control valve 802 is closed, the water volume in the mixing tank 9 increases and blocks the water passage 11, maintaining the water volume in the mixing tank 9. Simultaneously, the block 14 seals the outlet of the dyeing unit 7, preventing excessive dye discharge. With this setup, the mixing tank 9 can also be used to thoroughly mix clean water and dye.

[0056] Preferably, the water passage 11 is located above the dyeing unit 7 and close to the discharge end of the dyeing unit 7. When the first water level control valve 802 is opened to continuously replenish water, the clean water falling from the water passage 11 passes through the dyeing unit 7 and continues to fall with some dye. Under the collision and impact of the water flow and the mixing tank 9, the clean water and dye are fully mixed.

[0057] Furthermore, a limiting rail 22 is fixed to the inner wall of the mixing tank 9. The limiting rail 22 is configured to limit the blocking block 14 so that the blocking block 14 can move vertically along the inner wall of the mixing tank 9. With this structure, not only the blocking block 14 can be limited, but the float 12 can also be limited.

[0058] In this embodiment, refer to Figure 7 It also includes a mixing section, which is located in the first pipeline 4 and connected to the liquid outlet of the lower chamber. A spiral plate 15 is fixed on the inner wall of the mixing section so that a spiral channel is formed in the first pipeline 4.

[0059] Specifically, a spiral plate 15 is installed in the first pipeline 4, so that the water and dye that have been initially mixed in the mixing box 9 can be guided and further mixed under the action of the spiral channel, so that the product discharged from the first pipeline 4 is a liquid with a relatively uniform color.

[0060] In this embodiment, refer to Figure 6 The dyeing unit 7 includes: a storage box 701, fixed to the outer wall of the water tank 1, with an opening at the top of the storage box 701; an extrusion block 702, disposed inside the storage box 701 and slidingly engaged with the inner wall of the storage box 701, the extrusion block 702 being configured to extrude dye from the storage box 701; and a guide pipe 703, one end of which is connected to the bottom outlet of the storage box 701, and the other end of which is connected to the first pipeline 4.

[0061] Specifically, the storage box 701 is used to hold the dye. The storage box 701 is connected to the lower chamber of the mixing box 9 through the guide pipe 703 to send the dye into the lower chamber to mix with water. The extrusion block 702 is used to block the top opening of the storage box 701 and provide a certain extrusion force to facilitate the discharge of the dye.

[0062] Furthermore, a vertical rod 704 is fixed to the top of the extrusion block 702, and at least one counterweight 705 is fitted onto the vertical rod 704. In actual experiments, the counterweight 705 can be set accordingly based on the selected dye material and the predetermined dye discharge speed to apply pressure to the dye.

[0063] In this embodiment, refer to Figure 3 The control unit 6 includes: a first opening and closing valve 601 connected to the water inlet of the first pipeline 4; a second opening and closing valve 602 connected to the water inlet of the second pipeline 5; and a controller 603 fixed to the outer wall of the water storage tank 1 and connected to the first opening and closing valve 601 and the second opening and closing valve 602 via a connecting line, configured to control the opening time of the first opening and closing valve 601 and the second opening and closing valve 602.

[0064] In a specific embodiment of the present invention, the opening time of the first opening and closing valve 601 and the second opening and closing valve 602 is controlled by a controller 603. That is, the controller 603 has a touch screen or a button screen on its surface. By adjusting the opening time displayed on the controller 603, the opening time of the first opening and closing valve 601 and the second opening and closing valve 602 can be controlled, thereby conducting an experiment on the amount of water injected in the same amount of time.

[0065] In another specific embodiment of the present invention, a flow meter is provided on the first opening and closing valve 601 and the second opening and closing valve 602, and the flow meter is connected to the controller 603 to monitor the water flow. By adjusting the water flow of the first opening and closing valve 601 and the second opening and closing valve 602 on the controller 603, an experiment is conducted on the water injection time under the same water injection volume.

[0066] The controller 603 is a power switch control device composed of a single-chip microprocessor as its core and electronic circuits. It can adopt existing structures and conventional usage methods.

[0067] The first and second opening / closing valves 601 and 602 can be solenoid valves. An external power source, such as a battery, is also required to power various electronic devices.

[0068] In this embodiment, refer to Figure 1 A transparent cover 16 is provided on the side wall of the water storage tank 1. The transparent cover 16 is configured to observe the water level in the water storage tank 1, and the transparent cover 16 is equipped with a scale 17.

[0069] Specifically, the transparent cover 16 and the scale 17 work together to observe the water level in the water storage tank 1.

[0070] In this embodiment, refer to Figure 1 , Figure 2A water-separating frame 18 is fixed to the inner wall of the water storage tank 1. A water-separating plate 19 is installed inside the water-separating frame 18. The water-separating plate 19 divides the water storage tank 1 into a first chamber and a second chamber. The first chamber is connected to the first pipeline 4, and the second chamber is connected to the second pipeline 5.

[0071] Specifically, in experiments involving the same water volume but different injection times, the water tank 1 can be divided into two equal chambers (first and second) using a baffle plate 19, and equal amounts of water can be injected into each chamber. The experiment ends when the water in both chambers has completely drained. With this setup, only the first and second valves 601 and 602 need to be normally open to conduct experiments on the injection time for the same water volume.

[0072] Alternatively, in experiments involving different amounts of water injected at the same time, the water tank 1 can be divided into two equal chambers (first and second) using a baffle plate 19, and equal amounts of water can be injected into each chamber. An infiltration time is set, and the water level in the first and second chambers is observed at predetermined time points. With this setup, only the first and second on / off valves 601 and 602 need to be normally open to conduct experiments on the injection time for the same amount of water.

[0073] When conducting other experiments, the baffle plate 19 can be moved upwards so that the first chamber and the second chamber are connected through the bottom of the baffle plate 19.

[0074] In this embodiment, refer to Figure 1 It also includes a support frame 20, which is set above the inner ring 2 and the outer ring 3. The water storage tank 1 is set on the top surface of the support frame 20. The bottom surface of the support frame 20 is fixed with a mounting bracket 21, and the water level control unit 8 is fixed on the mounting bracket 21.

[0075] Specifically, the support frame 20 includes four legs and a platform fixed on the legs. The platform is arranged above the inner ring 2 and the outer ring 3 via the legs. The water tank 1 can be fixed on the top surface of the platform or placed on the top surface of the platform.

[0076] The mounting bracket 21 is fixed to the bottom surface of the platform, and the first liquid level sensor 801, the second liquid level sensor 803, the first control console, and the second control console are fixed on the mounting bracket 21.

[0077] Specifically, during the experiment, the inner ring 2 and outer ring 3 are placed first, then the support frame 20 is placed, the various structures are connected, water is filled into the water tank 1, and dye is filled into the material storage box 701. Then, the controller 603 is adjusted according to the experimental needs to carry out the infiltration experiment.

[0078] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
