Online monitoring intelligent early warning system for coal mine water burst

Abstract

The invention discloses an online monitoring intelligent early warning system for coal mine water burst. The online monitoring intelligent early warning system comprises a workstation host computer, an acoustic-optical early warning device, a transducer, and an integrated intelligent water quality sensor monitoring box, wherein the monitoring box comprises a barrel body, a plurality of water quality sensors, filter screens arranged at the two ends of the barrel body, an upper steady flow plate, a lower steady flow plate and a plurality of rows of split steady flow plates; the upper steady flow plate and the lower steady flow plate are mounted in the barrel body, transversely arranged, and extend to the filter screens at the two ends of the barrel body; the split steady flow plates are mounted in the barrel body, longitudinally arranged, and extend to the filter screens at the two ends of the barrel body; a plurality of flow guiding holes are formed in the upper steady flow plate, the lower steady flow plate and the rows of split steady flow plates; the rows of split steady flow plates are arranged between the upper steady flow plate and the lower steady flow plate; each row of the split steady flow plates comprises left-section plates and right-section plates; the left-section plates and the right-section plates are disconnected and communicated with the cavity, between the upper steady flow plate and the lower steady flow plate, of the barrel body. The online monitoring intelligent early warning system can effectively and quickly detect the water quality in the underground in-advance water detection process, and can carry out early warning in advance on the conventional water burst situation.

Description

technical field [0001] The invention relates to a water quality detection and early warning device, in particular to an intelligent early warning system for coal mine water inrush online monitoring, which can be widely used in the fields of hydrogeology, engineering geology, environmental geology, tunnel engineering and the like in mining areas. Background technique [0002] At present, there are two types of known water quality detection and early warning equipment (early warning devices). When testing water quality, the steps are to obtain water samples first, then add reagents to the water samples, digest and cool them as required, and finally measure and read in the detector. During the entire measurement process, there are several problems: 1. One is that the operation process is relatively complicated and requires professional and technical personnel to operate; the other is that most of the operation process needs to be completed in the laboratory or studio, the measu...

Problems solved by technology

[0002] At present, there are two types of known water quality detection and early warning equipment (early warning devices). When testing water quality, the steps are to obtain water samples first, then add reagents to the water samples, digest and cool them as required, and finally measure and read in the detector. During the entire measurement process, there are several problems: 1. One is that the operation process is relatively complicated and requires professional and technical personnel to operate; the other is that most of the operation process needs to be completed in the laboratory or studio, the measurement time is long, and it is impossible to quickly distinguish; the third is that different ions in the water quality need to be added. Reagents, the operation is relatively cumbersome

Another type of water quality detection and early warning equipment is a large-scale water quality detection work platform, which consists of a mine water source rapid identification workstation host, pure water machine (or ultrapure water machine), electromagnetic stirrer, system workbench, chemical test water table, The corresponding chemical reagents and water source rapid identification workstation software are composed. When testing water quality, the water sample needs to be collected first, then taken to the laboratory, and the corresponding reagents are added according to the ions to be measured, and placed on the system workbench or chemical laboratory according to requirements. Ion detection and readings are carried out on the test water table. During the entire measurement process, there are these problems: first, the operation process is relatively complicated and must be completed by a professional test researcher; second, the water sample needs to be sent to the laboratory, and all operations The process must be completed in the laboratory, the detection time is long, and it is impossible to achieve rapid discrimination and early warning; third, during the test, different reagents need to be added to test different ions, and it needs to be operated on the corresponding workbench. The test process is relatively cumbersome. High quality requirements for operators

[0003] The above technologies have not given specific details on how to make the coal mine water inrush online monitoring intelligent early warning system not only effectively solve the rapid detection of water quality in the advanced water exploration in the mine, but also provide early warning for the occurrence of water inrush. guidance program
