Description

Technical Field

[0001] The present application relates to the technical field of underground coal mine monitoring equipment, and in particular to a multi-parameter water quality detection device for mines. Background Art

[0002] The hydraulic support on the working face is a structure used to control the mine pressure in the coal mining working face. The mine pressure acts on the hydraulic support in the form of external load. In the mechanical system of the interaction between the hydraulic support and the surrounding rock of the mining face, if the combined force of the hydraulic support's supporting components and the combined external force of the roof acting on the hydraulic support are exactly aligned, then the hydraulic support is well adapted to the surrounding rock of the mining face.

[0003] Traditionally, hydraulic supports in fully mechanized coal mining working faces primarily use emulsions as the transmission medium. Emulsion stability is crucial; poorly stable emulsions can cause hydraulic system malfunctions, even damage equipment, shorten service life, and cause malfunctions. Emulsions are oil-in-water hydraulic fluids, typically comprising over 95% water. The quality of the water used to prepare the emulsion directly impacts its quality. With the widespread adoption of electro-hydraulic control systems for supports, the requirements for emulsion water quality have become even stricter, placing higher demands on water hardness (conductivity), pH, and other water quality parameters.

[0004] Therefore, it is particularly important to realize real-time online monitoring of the water quality used for liquid preparation and to transmit the detection data to underground water treatment equipment and ground dispatching center in real time, so that managers of relevant units in coal mines can grasp the real-time water quality status.
