Underground particle collecting device based on ultrasonic standing waves

The invention relates to an underground particle collecting device based on ultrasonic standing waves. The underground particle collecting device comprises a central controller, a terminal server, a detection device and moving devices, wherein the central controller is connected with the terminal server; and the detection device comprises an environment collection and analysis module and a safetymonitoring and analysis module. The underground particle collecting device has the beneficial effects that a certain guide rail is paved in a well passage; a plurality of moving devices are arranged on the guide rail; a sound wave motor is movably connected inside each moving device; the sound wave motor emits standing waves through a sound wave emitter; the standing waves realize good maneuverability on tiny particles, so that suspended particles generate migration movement; the dust removal is more thorough; the directivity is realized; a wave source generator is arranged in a roadway; the particles are concentrated
