Direct injection pushing device capable of automatically supplementing electric power

The invention belongs to the technical field of power devices, aims to solve the technical problems of serious pollution, propeller slipping and high use cost in the propelling process in the prior art, and provides a self-compensation electric power direct injection propelling device which comprises a tubular shell, an enameled coil, a straight guide pipe and an impeller rotor assembly which are sequentially arranged from outside to inside. Flange plates are arranged at two ends of the shell; one end is an air inlet end and is connected with an impeller generator; the impeller rotor assembly comprises a central rotating shaft and three tubular intensive supercharging impellers arranged on the central rotating shaft, and powerful magnet ring plates are fixedly arranged on the outer sides of the three tubular intensive supercharging impellers; a hollow conical rotating seat is arranged on the side, close to the impeller rotor assembly, of the flange plate and located in the shell. The direct injection pushing
