Underground coal mine intelligent air window and adjusting system and method thereof

Abstract

The invention discloses an underground coal mine intelligent air window and an adjusting system and method thereof, and belongs to the technical field of mine air windows. The underground coal mine intelligent air window comprises a shutter air cabinet; the shutter air cabinet is of a cuboid rectangular structure and comprises a cabinet body, movable sashes and an arc-shaped air guiding plate; anair inlet and an air outlet are formed in the rear end of one side of the cabinet body correspondingly, and the multiple movable sashes are arranged at the air inlet; a pneumatic control assembly controlling the opening angles of the movable sashes is mounted on one side of the air inlet, and an angle sensor detecting the opening angles of the movable sashes is further mounted on one side of the air inlet; and the arc-shaped air guiding plate is fixed into the cabinet body. It is proposed for the first time that the pneumatic control assembly is adopted, compressed air serves as power to adjust the angles of the movable sashes of the shutter air window, thus the air passing section is quickly and accurately adjusted, the situation that the air window area is changed due to misoperation ofnon-ventilation personnel can be prevented, and the air volume is reliably controlled.

Description

technical field [0001] The invention relates to the technical field of mine windshields, in particular to an underground smart windshield for coal mines and an adjustment system and method for the smart windshield. Background technique [0002] At present, the windshields for mine adjustment mainly include non-pressure panoramic windshields, adjustable louver windshields, wind pressure power windshields and dial adjustment windshields. In order to meet the ventilation requirements of the daily production of coal mines, it is necessary to manually adjust the wind passing section of the windshield frequently. Not only is the project very large, but also requires regular inspections. It is impossible to adjust it in real time when the air volume deviates, and there are certain potential safety hazards. At the same time, it is difficult to ensure the adjustment of uniform speed and micro-variation by manual operation, resulting in large fluctuations in air volume, resulting in l...

Problems solved by technology

In order to meet the ventilation requirements of the daily production of coal mines, it is necessary to manually adjust the wind passing section of the windshield frequently. Not only is the project very large, but also requires regular inspections. It is impossible to adjust it in real time when the air volume deviates, and there are certain potential safety hazards. At the same time, it is difficult to ensure the adjustment of uniform speed and micro-variation by manual operation, resulting in large fluctuations in air volume, resulting in low air volume adjustment accuracy; the air windows are all set in the wall, and the deformation of the roadway will easily lead to damage to the air windows and affect the ventilation effect, and the air windows cannot be adjusted. Secondary use, resulting in waste of equipment
