AI Technical Summary
Existing water exploration and drainage devices cannot effectively remove slag during drilling, resulting in a mismatch between slag removal and drainage, which affects operational safety and equipment reliability.
The system employs a flow-guiding and sealing mechanism, including a plug, a flow-guiding cylinder, and a moving component. Through the coordination of drill rod rotation and linear motion, it enables continuous drilling and water exploration operations. The flow-guiding cylinder's inlet and the plug's moving sealing function separately handle the slag discharge and drainage processes, preventing slag and water mixing.
This technology enables the smooth discharge of coal slag, rock debris, and mud during the rotation and linear motion of the drill rod, while also allowing for the controlled removal of water from the borehole. This reduces the risk of water inrush and blowouts, and improves operational safety and equipment reliability.
