| titleOfInvention | Variant-frequency vibration permeability-increasing gas pumping device in hole |
| abstract | The utility model provides variant-frequency vibration permeability-increasing gas pumping device in a kind of hole,Including variable frequency type ultrasonic generator,Ultrasonic transducer,Gas pumping pumps,Gas pumping pipe,Electric cabinet,Mounting shell,One end of gas pumping pipe is connected with gas pumping pump,The other end has porous section,Porous section of outer wall is equipped with magnetosphere,Mounting shell has the electromagnetically cambered surface to match with gas pumping pipe outer wall shape,Ultrasonic transducer is fixed in mounting shell,Electromagnetically cambered surface by double-point double-throw switch after the first explosion-proof conducting wire series connection with electric cabinet by being connected,Ultrasonic transducer after the second explosion-proof conducting wire series connection with supersonic generator by being connected,The magnetism of electromagnetically cambered surface can be changed by adjusting double-point double-throw switch change electric current,Mounting shell is fixed on porous section of gas pumping pipe or on drill hole inner wall by magnetosphere and the electromagnetically attraction between cambered surface or repulsive interaction. |
