The utility model relates to a down-hole oil
pipe rotation preventing type electrical dirty scraping device. A main body is designed into cylindrical-shaped, a
fishing head, a centralizer fixed body connected with the
fishing head through thread and a rotation preventing arm fixed body connected with the centralizer fixed body through thread are arranged form the upper part to the lower part in sequence, cable holes are arranged at the centers of the
fishing head and the centralizer fixed body, a bidirectional
cam axle equipped with a cable hole is arranged at the center of the rotation preventing arm fixed body, the upper end of the bidirectional
cam axle is connected with the rotation preventing arm fixed body through a
screw cap, the lower end is connected with the sheathing thread of a motor through the central hole of the rotation preventing arm fixed body, a cable is connected with the motor through a sealing plug, a sealing sleeve, a pressing screw sleeve, a sliding needle seat and a fixed seat, the pressing screw sleeve is connected with the bidirectional
cam shaft through
tread, the pressing sealing sleeve and the sliding needle seat are connected with the fixed seat through thread, the fixed seat is connected with the sheathing thread of the motor through thread, the sheathing thread of the motor is connected with a bearing sleeve through thread, the bearing sleeve is connected with a falling prevention screw sleeve through thread, a motor axle is connected with a connecting axle, and the connecting axle is connected with a scraper through thread and a pin. The invention solves the problem that the oil
pipe prevents the dirty scraping.
