Problems solved by technology

[0005] However, when the above two sensor probes are installed, the pin-type sensor probe needs to dig a deep pit showing different depths of soil in the soil, insert the sensor probe into a specific section of the soil at a fixed point, and then backfill and bury the sensor probe. Cannula sensor probes require on-site assembly
The installation methods of the above two sensor probes not only increase the workload of sensor probe installation, but also increase the difficulty of sensor installation, and also increase the cost of sensor installation and construction.
In addition, the pin-type sensor probe has a limited probe length, limited contact area with the soil, and low detection accuracy

Abstract

The invention particularly relates to a threaded soil moisture measuring device. The threaded soil moisture measuring device is characterized in that a filling and sealing body is rod-shaped, and a spiral bulge is integrally formed on the peripheral surface of the filling and sealing body; the probe is spiral and is fixed on the spiral bulge along the extension direction of the spiral bulge; the cable is fixed in the potting body and is connected with the probe. According to the invention, the threaded soil moisture measuring device is arranged to be the integrally-formed filling and sealing body, and the probe and the cable are respectively fixed on the spiral bulge and in the filling and sealing body in a filling and sealing manner, so that the defects of a multi-module assembly manner are overcome, field assembly is not needed, the sealing performance of the threaded soil moisture measuring device is enhanced, and meanwhile, by means of the spiral protrusions arranged on the rod-shaped filling and sealing body which is long enough and the close contact between the spiral probe and the soil, installation is easy, and meanwhile the accuracy of measuring the water content of the soil at different depths can be achieved.

Description

technical field [0001] The invention relates to the technical field of soil parameter measuring devices, in particular to a threaded soil moisture measuring device. Background technique [0002] The measurement of soil moisture is one of the important components of current meteorological environment monitoring. It is of great significance to combat drought and reduce disasters, guide agricultural production and protect the ecological environment. Among many soil parameters, soil moisture is the focus of people's attention. The current relatively mature measurement methods for soil moisture measurement include drying method, time domain reflection method, frequency domain reflection method, capacitance method, standing wave method, etc. The dielectric constant, and then according to the relationship between soil moisture and dielectric constant, use the regression method to calibrate the soil moisture. [0003] In engineering projects, time-domain reflectometry and frequency...
