Groundwater Level Observation Device for Hydrogeological Bore

Abstract

The invention discloses an underground water level observation device for hydrogeological holes. The underground water level observation device comprises a scale, a water level measuring unit and a control unit. The scale is used for measuring the water level tube entry depths of the water level measuring unit; the water level measuring unit is used for measuring water levels and comprises a shell, the shell is of a square barrel structure, salt is arranged in the shell with a height h, openable insulating covers are arranged on the top of the shell, insulating plates are arranged at the bottom of the shell, electrode plates are arranged on a first group of vertical opposite planes, and filter cloth capable of filtering underground water is arranged on a second group of vertical opposite planes; the scale is fixedly connected with the insulating covers; the control unit comprises a resistance value acquisition unit, a microprocessor, a power supply module and a display; the power supply module is used for supplying power for the electrode plates, the resistance value acquisition unit and the microprocessor, and the electrode plates are connected with the power supply module by wires. According to the scheme, the underground water level observation device has the advantage that the problems of low underground water level measurement accuracy and high errors in the prior art can be solved by the aid of the underground water level observation device.

Description

technical field [0001] The invention relates to the technical field of long-term observation of hydrogeological holes requiring high observation accuracy, and in particular to a groundwater level observation device for hydrogeological holes. Background technique [0002] Groundwater is the water deposited in the voids of rocks and loose sediments below the ground. Groundwater is closely related to human beings. Groundwater with a huge content is the main source of drinking water. [0003] However, too much or too little groundwater will cause some harm to people's lives. For example, too much groundwater will cause railways and roads to collapse, submerge mining tunnels, and form swamps. At the same time, it should be noted that groundwater is an important part of the water cycle, and it is in a dynamic balance. Blind and excessive development will easily cause problems such as underground cavities and stratum subsidence. Groundwater level information is an important basis ...
