Description

Technical Field

[0001] The utility model relates to the technical field of soil water potential measurement, in particular to a device for continuously and automatically measuring soil water potential on site. Background Art

[0002] Soil water potential reflects the ease with which soil releases water from its pores under external environmental conditions. It can also effectively indicate the water absorption and retention capacity of plant roots in agricultural irrigation. Continuous and accurate measurement of soil water potential is crucial for understanding the on-site soil dryness and wetness conditions and determining the stability of on-site engineering soil structures.

[0003] The existing patent document with technical authorization announcement number CN220188523U provides a device for continuously and automatically measuring soil water potential on site. This utility model, in this measurement scheme, only requires that the saturated water potential measuring instrument be buried at a certain depth in the soil on site. The subsequent soil water potential data collection and automatic protection when the measuring range is exceeded are all controlled by indoor software, which greatly reduces the multiple disturbances to the on-site in-situ soil caused by the existing water potential measuring instrument being vaporized, taken out, re-saturated, and re-buried. At the same time, it also reduces the costs generated by on-site drilling equipment and manpower operations, making on-site soil water potential measurement simpler, more convenient, and more environmentally friendly.

[0004] However, when using the existing on-site continuous automatic measurement of soil water potential, it is not convenient for workers to control the verticality of the water potential detection head. When using the measuring device to perform automatic soil water potential measurement operations, the existing technology is easily affected by the terrain and external force factors during the insertion of the water potential detection head, and the water potential detection head is easily inserted at an angle, which will cause the actual insertion depth of the detection head to be inconsistent with the expected insertion depth, which will directly affect the measurement accuracy of the soil water potential.
