Description

Technical Field

[0001] This utility model relates to the field of soil permeability measurement technology, and in particular to an automatic soil permeability measurement device. Background Technology

[0002] An automatic soil permeameter is an intelligent device used to measure soil permeability. Its main function is to quickly assess soil permeability, water holding capacity, and drainage characteristics by automatically monitoring and recording the infiltration rate and flow rate of water in the soil. This instrument is widely used in agricultural irrigation planning, soil and water conservation research, geological disaster early warning (such as landslides and debris flows), and soil investigation before engineering construction. It provides accurate data support for soil hydrological analysis, ecological environment monitoring, and engineering seepage prevention design, effectively improving the efficiency of field operations and the continuity of data, and reducing human error.

[0003] Existing automatic soil permeability meters still have some problems in use. For example, they can only measure permeability through a single water injection method and cannot simulate the rainfall infiltration process under real natural conditions. This limits their application value in research that requires simulating rainfall scenarios, such as farmland soil and water conservation and slope stability assessment.

[0004] To address these issues, we provide an automated soil permeability meter. Utility Model Content

[0005] The technical problem to be solved by this invention is that the existing technology has the disadvantage of being unable to simulate the rainfall infiltration process under real natural conditions. To address this, we propose an automatic soil infiltration meter.

[0007] Preferably, the circular plate has a sliding groove inside, and the slider is slidably connected inside the sliding groove.

[0008] Preferably, guide plates are fixedly connected to both sides of the transmission rod surface, and a through groove is opened inside the circular plate, through which the circular plate is slidably connected to the inside of the guide plate.

[0012] Preferably, the connecting plate has an installation groove inside, which is used to install the water outlet and the spray head.

[0013] The technical effects and advantages of this utility model are as follows: 1. This utility model, through the setting of the transmission motor, can drive the circular plate and connecting plate to rotate horizontally. With the setting of the cylinder and slider, it can realize the switching of multiple functions, thereby achieving the purpose of simulating natural rainfall and water injection measurement, and more realistically reproducing the infiltration effect of natural precipitation on soil, significantly improving the applicability of the equipment in the fields of farmland soil and water conservation research, slope stability assessment and other fields.

A connecting plate 10 is connected, and an outlet 11 and a spray head 12 are provided inside the connecting plate 10. The outlet 11 and the spray head 12 can be easily changed to simulate rainy weather and normal measurements. Solenoid valves 20 are provided on the surface of the outlet 11 and the spray head 12. The solenoid valves 20 can control the on / off state and flow rate of the water flow to achieve accurate simulation of the soil infiltration process. Furthermore, the water flow speed of the outlet 11 and the spray head 12 can be changed by adjusting the opening degree of the solenoid valves 20 to adapt to the needs of different experimental conditions. A cylinder 13 is fixedly connected to one side of the top of the inner cavity of the bracket 3. A slider 14 is fixedly connected to the output end of the cylinder 13. The slider 14 is slidably connected to the inside of the circular plate 9.

[0023] Example 2 Please see Figures 1-5Based on embodiment 1, a sliding groove 15 is provided inside the circular plate 9, and the slider 14 is slidably connected inside the sliding groove 15. Guide plates 16 are fixedly connected to both sides of the transmission rod 8. The guide plates 16 can drive the circular plate 9 to rotate. A through groove is provided inside the circular plate 9, and the circular plate 9 is slidably connected to the guide plate 16 through the through groove. A water inlet pipe 17 is connected to the top of the water tank 4. A sealing cover 21 is provided on the top of the water inlet pipe 17. The sealing cover 21 can prevent external impurities from entering the water tank 4. A sealing groove 18 is provided inside the water outlet 11 and the spray head 12. A sealing ring 19 is fixedly connected inside the sealing groove 18. The sealing groove 18 and the sealing ring 19 can ensure the sealing performance of the water outlet 11 and the spray head 12 during use and prevent water leakage. A drain outlet is connected to the bottom of the storage box 2. An electric control valve is provided on the surface of the drain outlet. An installation groove is provided inside the connecting plate 10. The installation groove is used to install the water outlet 11 and the spray head 12.

[0024] Working principle: The user first injects water into the water tank 4 through the inlet pipe 17 and seals it. Then, according to the experimental requirements, the user selects the working mode of the outlet 11 or the sprinkler head 12. When simulating natural rainfall, the user starts the drive motor 7 through the external controller. The drive motor 7 drives the drive rod 8 to rotate, thereby causing the circular plate 9 and the connecting plate 10 to rotate horizontally. At the same time, the cylinder 13 drives the circular plate 9 to rise through the slider 14. The circular plate 9 then drives the sprinkler head 12 to rise through the connecting plate 10, thereby connecting the sprinkler head 12 with the outlet pipe 5. The solenoid valve 20 can control the water flow switch and flow rate of the sprinkler head 12. In addition, the electronic flow meter 6 can precisely adjust the rainfall intensity, such as light rain or heavy rain mode, so as to realize the simulation of different rainfall scenarios.

[0025] During routine water injection measurements, the user activates the drive motor 7 and cylinder 13 via an external controller. Cylinder 13 lowers the circular plate 9 via slider 14, and the circular plate 9 lowers the spray head 12 via connecting plate 10, thus disconnecting the spray head 12 from the outlet pipe 5. Then, drive motor 7 rotates drive rod 8, which in turn rotates guide plate 16, which in turn rotates circular plate 9. Circular plate 9 rotates outlet 11 and spray head 12 via connecting plate 10, aligning outlet 11 with outlet pipe 5. Then, cylinder 13 raises circular plate 9 via slider 14, and circular plate 9 raises outlet 11 via connecting plate 10, connecting it to outlet pipe 5. Solenoid valve 20 controls a stable water flow to vertically inject into the soil sample in storage box 2. During the infiltration process, water permeates through the soil layer and is discharged through the drain at the bottom of storage box 2. The electronically controlled valve automatically controls the drainage and records the infiltration flow rate with external metering equipment, thereby achieving the purpose of switching between different measurement functions.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
