Description

Technical Field

[0002] Groundwater refers to the water body below the earth's surface. It mainly exists in groundwater layers and is formed by rainfall, snowmelt and surface water seeping into the ground. Some groundwater also comes from underground aquifers. Groundwater is one of the important water resources and is widely used in water supply, irrigation and industrial production. Groundwater thermometer is a device used to measure groundwater temperature. It is generally used in groundwater resource investigation, geothermal energy utilization, environmental geochemistry and hydrogeology. Groundwater thermometer usually uses temperature sensor fixed by rope or cable, and places the sensor in groundwater to measure the temperature of groundwater. The temperature data on the sensor can be transmitted to the display or data recorder through the wire connected to the display.

[0003] When existing groundwater thermometers are used to detect groundwater temperature, the sensor itself may be inaccurately calibrated or gradually lose accuracy during use, resulting in deviations in the measurement results, thereby bringing uncertainty to groundwater temperature monitoring and related environmental analysis. This deviation may affect the accurate monitoring and analysis of groundwater temperature changes, and may have an impact on the rational use of groundwater resources and environmental protection.

[0024] By adopting the above solution, the connecting plate 4 can be quickly connected to the protective shell 5 through the mounting hole 42 , the insertion slot 43 and the limiting slot 44 .

The exhaust hole 54 is located at the lower end of the mounting block 51. There are two groups of hanging platforms 53, which are symmetrically distributed on the outer end of the protective shell 5. There are two groups of exhaust holes 54, which are symmetrically distributed on the side end of the protective shell 5.
