When the underground water level observation device works, firstly, the water inlet pipes 19 at the bottom ends of the water level observation mechanisms 8 are positioned at the bottom ends of the upper layer of stagnant water, the diving layer and the pressure-bearing water layer, and the water pressure of the corresponding underground water layer enables part of underground water to pass through the water inlet pipes 19 and enter the insulating connecting cover 81, then the liquid level inside the insulating connecting cover 81 pushes the sealing piston sleeve 87 to rise under the principle of a communicating vessel, the sealing piston sleeve 87 drives the insulating block 86 and the conducting resistor 83 to rise and extrude the insulating spring tube 88, when the water level descends, the sealing piston sleeve 87 is driven to move downwards along with the water level under the action of the restoring force of the insulating spring tube 88, the water pressure inside the insulating connecting cover 81 is consistent with the external water pressure, in addition, the displacement change occurs between the conducting resistor 83 and the conducting ring 82, and the distance between the bottom end of the conducting resistor 83 and the conducting rod 85 is shortened, the resistance between the two is reduced, the electric signal entering the water level data processing host 3 is correspondingly changed by the change of the resistance, the water level data of each groundwater layer is sent to the staff of the control room after being processed by the water level data processing host 3, the water level observation mode is not affected by water flow to shake and interfere, meanwhile, the bottom end of the electrified conducting rod 85 and the metal probe 810 are both positioned in groundwater, the conductivity of each groundwater layer can be known in time by matching with the conductivity meter 811, the conductivity meter 811 is connected with the water level data processing host 3 to send the conductivity data of each groundwater layer to the staff of the control room, the staff knows the solute content of different groundwater layers through the conductivity data, monitors the quality of the groundwater and provides reference for whether to mine the groundwater, the mechanism enables the underground water level observation device to have the capability of resisting water flow interference and measuring the conductivity of underground water when observing the underground water level, improves the accuracy of observing the underground water level, and can monitor the water quality change of the underground water.
