Description

Insulating earthing device of distribution network earth connection

Technical Field

The utility model relates to an earthing device, a distribution network earth connection insulation earthing device specifically says so.

Background

During the construction of a power distribution network, some operations need to be grounded so as to ensure the safety of workers, and the conventional grounding mode is to drill underground by adopting long screws, hand-cranking modes and the like so as to achieve the purpose of grounding. However, the conventional grounding device is relatively laborious to install and has poor insulation during operation.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model aims at providing a distribution network earth connection insulation earthing device.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a distribution network earth connection insulation earthing device, including the fixed horizontal insulation backup pad of insulating motor shell and insulating motor shell lower extreme, insulating motor shell is cylinder and vertical setting, be provided with the vertical gear motor who runs through insulating backup pad of motor shaft in the insulating motor shell, the motor shaft lower extreme then is fixed with interior hexagonal sleeve, the upper end of electrically conductive earth-boring threaded rod is outer hexagonal, and fixed cover has the insulating plastic cover, the insulating plastic cover is inserted in interior hexagonal sleeve, the top both ends of electrically conductive earth-boring threaded rod still are provided with integrative and bilateral symmetry's wiring hangers respectively, the insulating motor shell top is fixed with the rechargeable battery who takes the shell, rechargeable battery supplies power for gear motor, and just rotate through reversing the on-off control positive reversal.

The utility model adopts the mode that the speed reducing motor drives the conductive ground screw rod to rotate to drill underground, thereby not only saving labor, but also having high efficiency and being convenient for fixing and disassembling; the conductive ground drilling threaded rod can be fully contacted with the ground, so that a good conductive effect is achieved; the conductive earth-drilling threaded rod is used for grounding, the conductive earth-drilling threaded rod is in contact with the inner hexagonal sleeve, the speed reduction motor and the like through the insulating plastic sleeve, the insulating plastic sleeve is in contact with hands during operation, a good insulating effect can be achieved, contact of the conductive earth-drilling threaded rod with an underground wire and the like during earth drilling is avoided, and the conductive earth-drilling threaded rod is safer to use.
