Technical Field

[0001] The utility model relates to a monitoring device, in particular to an underground water level monitoring device, belonging to the technical field of water level monitoring. Background Art

[0002] Groundwater level monitoring devices are special instruments used to monitor groundwater level changes, usually composed of sensors, data acquisition systems, data transmission devices and data processing software. These devices play a vital role in many fields, especially in water resources management, mine safety monitoring and geothermal resource development. By monitoring groundwater level changes in real time, we can understand the distribution and dynamic changes of water resources, and provide a scientific basis for the rational development, utilization and protection of water resources.

[0003] In the prior art, there is a groundwater level monitoring device disclosed in the announcement number CN221053676U, which includes a support frame, a cable retracting device, a cable meter, a submersible device, and a water-contacting probe. By setting the submersible device and the well wall, a nearly vertical drop effect can be achieved, and the effect of the cable retracting device on the submersible device will not be affected. By setting two water-contacting probes, the effect of accurate water level can be achieved, and the judgment of the water level position of a single water-contacting probe can be avoided due to water splashes. It achieves the effect of measuring the cable meter by setting a cable meter, the measurement result can be accurate to millimeters, and the error caused by manual measurement can be avoided. It is low-cost, meets scientific research requirements, and is easy to manage.

[0004] In the above technical solution, a cable meter is set up to achieve the effect of measuring the cable, and the measurement result can be accurate to millimeters. However, since the detection probe is in water for a long time, it is impossible to clean the probe, which causes impurities to easily adhere to the surface of the probe, affecting the monitoring effect. In view of this, a groundwater level monitoring device is provided to overcome the above defects. Utility Model Content
