Description

TECHNICAL FIELD

[0001] The utility model relates to soil detection technical field, concretely is a soil resistivity grounding detection device. BACKGROUND

[0002] In soil resistivity grounding detection, four-pole method measurement is a commonly used method, which is based on electromagnetic field theory, and the soil resistivity is calculated by measuring the resistance value in the soil. In order to ensure the accuracy of measurement, certain operation steps need to be followed. First, four electrodes are inserted into the soil at equal intervals S. The insertion depth of the electrode should be 1 / 20 of S to ensure good contact between the electrode and the soil. Then, the instrument is placed stably on the ground and the pointer is adjusted to the standard position. Then, four wires are connected to the corresponding electrodes respectively to ensure correct connection. According to the instruction manual, set the appropriate multiplier switch and measurement range, start the measuring instrument to measure the resistance value. Finally, according to the measurement result and electrode spacing S, the soil resistivity is calculated using the formula ρ = 2πsR (ρ is the soil resistivity, R is the measured resistance value, s is the electrode spacing). The entire measurement process needs to strictly follow the operation steps to ensure the accuracy and reliability of the measurement results.

[0003] In soil resistivity grounding detection, although four-pole method measurement is widely used as a classic method, there are some obvious defects in its actual operation. Among them, the spacing between each ground needle is particularly prominent. In actual operation, due to the complex and changeable soil environment, it is often difficult to ensure that four electrodes are inserted into the soil at equal intervals S. This not only increases the difficulty of operation, but also may have a great impact on the measurement results, leading to errors in the calculation of soil resistivity. In addition, the large number of wire connections is also a major defect of the existing detection device. In four-pole method measurement, four wires need to be connected to the corresponding electrodes. This not only increases the complexity of operation, but also greatly reduces the portability of the entire detection device. Too many wires not only easily get tangled, but also may come loose or break during use, thereby affecting the accuracy and stability of the measurement. UTILITY MODEL CONTENTS
