Hydrogeological exploration underground water level observation device

Abstract

The invention discloses a hydrogeological exploration underground water level observation device. The hydrogeological exploration underground water level observation device comprises an observation well, a protection shell, an observation mechanism used for observing the underground water level, a positioning mechanism used for fixing the protection shell in the observation well, a locking mechanism used for locking the positioning mechanism, an unlocking mechanism used for unlocking the locking mechanism and a paying-off mechanism. According to the hydrogeological exploration underground water level observation device, the protection shell and the positioning mechanism are arranged, so that sensors are prevented from being in contact with the well wall of a detection well, and therefore the sensors are protected; accurate angular displacement is output through an observation driving motor and a paying-off driving motor, the descending height of the sensors is controlled, and the accuracy of water level measurement can be improved; the protection shell is fixed through the positioning mechanism, so that the sensors ascend and descend along a straight line, and the observation value is more accurate; manual operation is not needed in the observation process, remote control can be realized, and timing observation is realized; and the two sensors are arranged, so that the situation that the water level rises too fast and overflows all parts when the observation interval time is long can be avoided, and the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a groundwater level observation device for hydrogeological exploration. Background technique [0002] At present, the observation of the groundwater level is mainly to open a vertical observation well at the selected observation place, and observe through the steel ruler water level gauge. When using it, the end of the steel ruler water level gauge is lowered along the observation well. When it drops to the groundwater level, a warning will be issued, and the operator on the upper part will observe it, which has the following disadvantages: [0003] 1. When the end of the steel ruler water level gauge is lowered, the probe part is not protected, and it is easy to collide with the inner wall of the detection well, resulting in damage to the sensing probe; [0004] 2. The water level contacted by the probe depends on experience. The accuracy of measuring the water l...

AI Technical Summary

Problems solved by technology

[0003] 1. When the end of the steel ruler water level gauge is lowered, the probe part is not protected, and it is easy to collide with the inner wall of the detection well, resulting in damage to the sensing probe;

[0004] 2. The water level contacted by the probe depends on experience, and the accuracy of measuring the water level is low. Affected by the fluidity of groundwater, the sensing probe will move, and the steel ruler may be in a tilted and non-vertical state in the well, resulting in inaccurate observations, which are different from the actual situation. There is an error in the value;

[0005] 3. This process needs to be completed by personnel at the observation site. At present, automatic observation of groundwater level cannot be realized, and manual observation is required every day.
