Intelligent time sequence monitoring device for soil water content

Abstract

The invention discloses an intelligent time sequence monitoring device for soil water content, and relates to the technical field of monitoring equipment. The intelligent time sequence monitoring device for the soil water content comprises a plurality of monitoring mechanisms, and the monitoring device further comprises a setting mechanism capable of being electrically connected with the monitoring mechanisms and a processing mechanism capable of being wirelessly connected with the multiple monitoring mechanisms. Each monitoring mechanism comprises a main body monitoring rod. A drill bit is fixedly connected to the bottom of the main body monitoring rod, a drilling sleeve rod is rotatably connected to the interior of the main body monitoring rod, and limiting blocks are fixedly connected to the two sides of the top of the main body monitoring rod. A data long-distance transmission device is carried on a soil water content sensor, so that long-distance transmission and receiving of real-time monitoring data of the soil water content in dynamic propulsion of a working face from an open-off cut to a mining stopping line are realized; therefore, the consumption of manpower and material resources of field monitoring work is reduced, and the test cost is saved.

Description

technical field [0001] The invention relates to the technical field of monitoring equipment, in particular to an intelligent time-series monitoring device for soil water content. Background technique [0002] Large-scale and high-intensity underground coal mining in semi-arid mining areas will change the physical and chemical properties of soil and soil water holding capacity, and disturb the spatial distribution of surface soil water. Due to the underground mining method, the overlying rock will collapse, crack and bend from the bottom to the top, resulting in a large number of cracks on the surface, which also increases the evaporation area of ​​soil water, which will lead to a decrease in soil water content. The study found that the spatial differentiation of soil moisture content in the pre-mining area, mining area, and goaf area of ​​the mining area was enhanced under mining disturbance, and the soil water content in the subsidence area was lower than that in the non-su...

Problems solved by technology

Soil moisture is often adsorbed on the surface of soil particles or stored in soil pores, and like external water, it also exists in solid, liquid, and vapor states. The types of soil moisture can be roughly divided into chemically bound water, There are three types of hygroscopic water and free water. Soil water content monitoring is an important basic work to guide the restoration of the ecological environment in semi-arid mining areas. The monitoring methods generally include manual soil extraction and drying methods and instrument rapid measurement monitoring methods. The method can be divided into fixed buried and portable. The soil structure and environmental changes at the location of the fixed buried monitoring instrument are difficult to keep pace with the field, and the representativeness of the monitoring data is poor. The portable monitoring instrument can be used directly in the field, but in drought or soil When the viscosity is high, it is difficult to insert into the soil, and it is easy to damage the monitoring instrument. It is difficult to maintain the same contact degree between the sensor of the monitoring instrument and the soil during multiple multi-point measurements, which affects the accuracy of monitoring data.

The above two monitoring methods are difficult to obtain the real-time dynamic change of soil moisture content during the dynamic advancement of the working face from the cutting hole to the stop production line, and cannot guarantee the timeliness of the soil moisture content change in the above dynamic process

In addition, large-scale fixed-point real-time field monitoring will inevitably consume a lot of human resources, and the work efficiency is slow.
