Abstract

The invention relates to the technical field of underground liquid level measurement, in particular to a self-cleaning liquid level measuring instrument and system. The self-cleaning liquid level measuring instrument comprises a liquid level measuring device, a liquid permeating device and a self-cleaning device; the liquid permeating device is arranged between the liquid level measuring device and the self-cleaning device; the liquid permeating device comprises a liquid permeating cavity, and the liquid permeating cavity is used for communicating with the liquid in an observation well so that the liquid level measuring device can detect the liquid level of the observation well; and the self-cleaning device is used for discharging sediments in the liquid permeating cavity out of the liquid permeating device. 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 with the control terminal. By adoption of the self-cleaning liquid level measuring instrument and system, the technical problem of measuring data distortion caused by silt, gravel and other sediments in the prior art can be solved.

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...
