Description

Technical Field

[0001] The utility model relates to the field of drainage control, in particular to an automatic drainage wind control device used in underground coal mines. Background Art

[0002] The underground mine drainage and air control system primarily includes automatic monitoring and control systems for drainage, ventilation, and compressed air. These systems work together to ensure safe mine operation and efficient management. Specifically, these systems consist of four components: a drainage control station, a ventilation control station, a compressed air control station, and a centralized control station. These stations are interconnected via remote network communications. These control stations can operate independently or centrally, achieving a management model that combines decentralized and centralized, local and remote control, ensuring optimal operation of the automatic control system under all circumstances. The drainage system is responsible for underground drainage, maintaining normal and safe coal mine production. Using an industrial control computer or explosion-proof PLC as its core control, this system monitors the operating status of various equipment in the underground coal mine drainage system and automatically controls the underground water pump drainage system, ensuring safe, reliable, energy-efficient, and economical operation. The ventilation system ensures air quality and safety within the mine. The system utilizes precise air volume and pressure sensors, as well as wind turbine speed sensors, to enable manual, automatic, and semi-automatic switching. Furthermore, it incorporates pedestrian and vehicle recognition devices, a video surveillance system, and other monitoring and surveillance devices, providing remote interfaces. The intelligent ventilation software system integrates geographic information systems and multiple monitoring systems to realize natural wind distribution solution, real-time solution of ventilation network and wind flow simulation under disaster conditions, and optimize the layout of ventilation systems and wind speed sensors.

[0003] In the existing technology, there are certain defects in the control part of the underground coal mine drainage wind control device, and the safety detection function of the underground coal mine is not perfect. Since the underground environment of the coal mine is humid and dim, there are defects in the waterproof system of the control device. Therefore, the utility model proposes an automatic drainage wind control device for underground mines. Utility Model Content
