AI Technical Summary
Existing coal mine drainage and anti-clogging mechanisms are inefficient at clearing larger impurities and long-term accumulated silt, requiring manual intervention, which affects the continuity of mining operations. Furthermore, they are complex in structure, have poor operational stability, and are difficult to adapt to the harsh underground environment of coal mines.
An anti-clogging mechanism including a stirring module and a stone removal module was designed. The rotating rod driven by the motor drives the stirring rod to stir the water flow. The protective shell protects the motor. The gear and ring system pushes the impurities to the collection chamber. Combined with the filter holes and the support plate, the cleaning is automated.
It ensures smooth water flow within the pipes, reduces sediment deposition and blockage by large impurities, lowers the difficulty of manual cleaning, improves automation and work efficiency, and ensures the continuous operation of the drainage system.
