AI Technical Summary
Existing soil permeability testing devices are inconvenient to measure the amount of water in the test tube after the test is completed, and the test paper lacks a limiting structure, which may cause the soil and water to shift or collapse, affecting the accuracy of the test results and the ease of operation.
A device comprising a test platform, a measurement component, a test component, a water tank, and a soil tank was designed. It employs a magnetic limiting ring and a weight sensor to achieve automated measurement and data display via wireless connection, ensuring a stable connection of the test paper, preventing water and soil displacement, and providing real-time data support through the weight sensor and display screen.
It enables convenient measurement of water volume in the test cylinder, improves the accuracy of test results and ease of operation, reduces resource waste, and simplifies the data observation and analysis process.
