Earthquake precursor monitoring system

Abstract

An earthquake precursor monitoring system comprises a bubble separating device, a constant flow device, an air pump and a gas analyzer, the constant flow device, the air pump and the gas analyzer are connected with the bubble separating device, the constant flow device conveys sucked underground water to the bubble separating device at a constant liquid flow, and the air pump conveys the sucked underground water to the bubble separating device at a constant gas flow. The bubble separation device mixes the gas and the fluid at a constant ratio, separates helium in the fluid, and conveys the gas and the fluid into the gas analyzer under the action of the sucking pump to analyze the helium content. Prediction before an earthquake is achieved through helium monitoring, reliable measurement of a monitoring value is achieved through a constant airflow ratio, interference of helium in air is avoided, and the prediction value is more scientific.

Description

technical field [0001] The invention relates to the field of earthquake monitoring, in particular to an earthquake precursor monitoring system. Background technique [0002] Earthquakes are frequent natural disasters in my country, involving a wide range of areas and causing great harm. Therefore, various methods and means of monitoring earthquake precursors, that is, abnormal phenomena that appear before earthquakes, have become an important content and focus of earthquake research. Studies have shown that underground fluids such as groundwater (well water, spring water, water contained in underground layers), oil and natural gas, and some other gases may be stored in underground rock formations. Instruments are used to monitor the chemical composition and certain physical quantities of these underground fluids. Research Their changes can help people predict earthquakes. Helium is a rare gas, and it can migrate farther under the condition of good channels. Helium can perme...

Problems solved by technology

[0003] Most of the existing technologies are based on the monitoring of radon to predict earthquakes, but compared with radon, helium has 7.4 times the chemical inertness and strong diffusion ability of radon, so it is more suitable for earthquake monitoring. The bubbling device is used to generate bubbles to separate the helium contained in the groundwater, but since the air also contains a small amount of helium, it has an impact on the detection results; and after bubbling under the existing technology, the generated bubbles cannot completely float up to The liquid surface breaks, especially the small bubbles, the surface stress is high and it is not easy to break, so that the helium cannot be released, and there are errors in the detection data
