Underground coal mine externally-hung type shutter air window and adjusting system and method of underground coal mine externally-hung type shutter air window

Abstract

The invention discloses an underground coal mine externally-hung type shutter air window and an adjusting system and method of the underground coal mine externally-hung type shutter air window and belongs to the technical field of mine air windows. An air window outer frame and an air window inner frame are of frame type structures, and the air window inner frame is embedded in the air window outer frame. A rotating shaft is fixed to each of the upper end and the lower end of each movable sash, wherein the rotating shaft is sleeved with a shaft sleeve and is connected with a rocking handle. Apneumatic control assembly is fixed to the middle of one side of the air window outer frame. Multiple movable sashes are distributed on the two sides, along the center line, in the air window inner frame at equal intervals, and the adjacent movable sashes are connected through the rocking handles. The pneumatic control assembly is connected with the rocking handles. The pneumatic control assemblyis further connected with a connecting rod mechanism. By means of the adjusting air widow, real-time automatic detection and adjustment are conducted on the air volume of a roadway, manual intervention is completely not needed in air volume adjustment, and in addition, accurate, fast and stable adjustment of the air volume can be achieved.

Description

technical field [0001] The invention relates to the technical field of mine windshields, in particular to an externally hung louver windshield in coal mines and an adjustment system and method for the 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 low...

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
