In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the safety grounding device for the transformer box comprises a grounding pipe, wherein the grounding pipe is a hollow pipe fitting, the lower part of the grounding pipe is fixedly connected with helical blades along the axial direction, through holes are uniformly arranged at the blade intervals of the helical blades and are communicated with the hollow part of the grounding pipe, the grounding pipe is placed in the grounding pipe, the hollow part of the grounding pipe is filled with a resistance reducing agent, the top part of the grounding pipe is outwards provided with outer helical teeth, the top part of the grounding pipe is provided with an insulating sleeve, the inner surface of the insulating sleeve is provided with inner threads corresponding to the outer helical teeth at the top part of the grounding pipe and is in threaded connection with the grounding pipe, the side surface of the insulating sleeve is horizontally provided with a handle which is vertically arranged with the grounding pipe and is in threaded connection with the insulating sleeve, and the design utilizes the grounding pipe to spirally attack into the ground for conducting, and the installation can be done manually.

Furthermore, the screw thread direction of the helical blade is opposite to the direction of the outer screw thread at the top of the grounding pipe, so that the insulating sleeve and the grounding pipe can be prevented from falling off in the installation process, and the use is convenient.

Further, the resistance reducing agent is a graphite resistance reducing agent.

Furthermore, the head of the lower end of the grounding pipe is conical, so that the grounding pipe can be conveniently attacked underground.

Further, the insulating sleeve is made of resin materials.

Furthermore, the top end of the grounding pipe is plugged by using epoxy resin, so that electric leakage is prevented.

After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model discloses use take helical blade's ground pipe and locate intraductal with the earth connection, attack the underground and electrically conduct, fill in the ground pipe and fall the resistance agent, fall the resistance agent and can go into along with the through-hole and get into the underground to obtain good electrically conductive effect, make ground connection safety, and utilize the handle can accomplish the installation, it is simple to use convenient.
