When a worker illegally contacts the grounding wire with the chuck 4 without inserting the grounding rod 1 into the ground, the cover plate 14 needs to be opened, the inner rod 42 extends out, the grounding wire is connected with the clamping part 44, the cover plate 14 is in an opened state, the second bevel gear 6 is separated from the first bevel gear 5, and the worker cannot insert the grounding rod 1 into the ground through the handle; after the grounding is finished, the worker should first separate the clamping portion 44 from the grounding wire of the grounding device, and then separate the grounding rod 1 from the soil. In this application, if the staff breaks rules and rules freely and does not separate earth connection and clamping part 44 after with earthing rod 1 and soil separation again, because apron 14 is in the open mode, the staff also can't rotate the handle and make earthing rod 1 and soil separation for the staff must operate according to the standard, has improved the security.
The implementation principle of the temporary grounding device for the construction site in the embodiment of the application is as follows: during grounding, the first driving piece 7 and the second bevel gear 6 rotate, the first bevel gear 5 is meshed with the second bevel gear 6 to drive the grounding rod 1 to be inserted into soil, the second bevel gear 6 drives the sleeve 9 to rotate in the rotating process, the sleeve 9 is in threaded connection with the grounding rod 1 to remove a rusted part on the grounding rod 1, the first bevel gear 5 and the sleeve 9 limit the grounding rod 1 to move in the vertical direction, and the grounding rod 1 is effectively guaranteed to be vertically inserted into the soil; after the ground connection, in first driving piece 7 removed earthing rod 1 to earthing box 3 through first bevel gear 5, the soil on earthing rod 1 was clear away to sleeve 9, effectively avoided remaining soil on the earthing rod 1, effectively ensured interim earthing device's electrically conductive effect.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
