Self-cleaning liquid level-measuring instrument and self-cleaning liquid level-measuring system thereof

Abstract

The invention relates to the technical field of underground liquid level measurement, and in particular to a self-cleaning liquid level-measuring instrument and a self-cleaning liquid level-measuring system thereof. The self-cleaning liquid level-measuring instrument comprises a liquid level-measuring unit and a self-cleaning unit; the self-cleaning unit is provided with a liquid passage cavity which is in contact with the liquid level-measuring unit; the liquid passage cavity is used for communicating with liquid in an observation well, so that the liquid level-measuring unit can detect the liquid level of the observation well; and the self-cleaning unit can drain deposit in the liquid passage cavity. The self-cleaning liquid level-measuring system comprises a control terminal and the self-cleaning liquid level-measuring instrument; and the self-cleaning liquid level-measuring instrument is electrically connected to the control terminal. The objective of the invention is to provide the self-cleaning liquid level-measuring instrument and the self-cleaning liquid level-measuring system thereof to solve the technical problem existing in the prior art that deposit, such as silt and gravels, can cause measured data distortion.

Description

technical field [0001] The invention relates to the technical field of underground liquid level measurement, in particular to a self-cleaning liquid level measuring instrument and a system thereof. Background technique [0002] The topsoil of the Quaternary system in the grassland area is relatively thick; therefore, there is a common engineering problem in most drilling and well drilling: after the well is completed, the well needs to be finely cleaned to completely discharge the mud deposited in the well during the well completion, so as to prevent or avoid the mud in the well. Blocking and affecting the normal work of hydrological observation equipment such as water level gauges placed in the well. [0003] During hydrological well casing insertion, equipment monitoring work and future maintenance, due to the influence of the hydrodynamic force of the underground aquifer, sediment, gravel and silt will still appear at the bottom of the well. The open cavity of the hydrol...
