Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, and more specifically, to a ventilation mechanism used in coal mining. Background Art

[0002] In the existing technology, ventilation is a very critical link in the coal mining process. At present, the ventilation mechanisms used in most coal mines are integrated structures, that is, the main components such as fans and motors are integrated into a closed unit. This design will cause inconvenience when the fan or motor fails. Due to the characteristics of the integrated structure, once the internal motor or fan needs to be inspected or repaired, it is usually necessary to disassemble the entire ventilation mechanism, which is not only time-consuming but may also affect the normal operation of the mine.

[0003] Existing ventilation mechanisms used in coal mines also have certain limitations in regulating exhaust ventilation volume. Usually, these mechanisms are equipped with simple adjustment functions and cannot accurately adjust the ventilation volume according to the real-time needs of the mine. This may lead to poor ventilation effects when the mine operating environment changes, affecting the safety and health of miners.

[0004] When the ventilation mechanism is not in use, most designs cannot achieve effective sealing. This may cause gas backflow, increasing the risk of gas accumulation inside the mine. Gas backflow not only affects the air quality of the mine, but also may increase the risk of safety accidents such as explosions and suffocation. Therefore, the existing ventilation mechanisms used in coal mines have certain deficiencies in structural design, maintenance convenience and safety of use, and need further improvement.
