The invention discloses an underground portable percussion
drill device based on pressure power generation, and belongs to the technical field of pressure power generation. The device comprises a drilling part, a dust discharging part, a self-
electricity-storage part and a percussion
drill main body part, the drilling part comprises a percussion
drill rod, a rotating sleeve, a mounting seat and a telescopic dust cover, and the dust discharging part comprises a dust discharging pipeline, a filter screen and a small
air blower; the self-power-storage part comprises a piezoelectric conversion device and a current integration device; the piezoelectric conversion device converts
mechanical energy generated by vibration of the percussion drill rod into
electric energy by
cutting magnetic induction lines through the permanent
magnet, and the current integration device generates stable
direct current from generated unstable
alternating current and directly stores the stable
direct current into the storage battery to supply power to the percussion drill. The problem that a traditional electric percussion drill needs to be charged frequently is solved, and the
viscosity problem caused by long-time use of a hydraulic percussion drill is also solved; the operation duration of a traditional percussion drill is prolonged, meanwhile, relevant policies of national green mines are responded, and
energy conservation and emission reduction are achieved.
