Description
Technical field
The utility model relates to oil exploitation corollary equipment technical field, is specifically related to a kind of earthing device that is suitable for the inflammable and explosive and provisional place uses such as petroleum works.
Background technology
Earthing device requires to be laid in below local frozen soil layer at present, the heat release welding should be adopted in each junction, the earth rod of pure red copper material is difficult to pierce hard underground of soil property by the electric impacting mode, and easily become the theft target and cause loss, thereby in the installation process, not only need a large amount of earth excavations, and certainly lead to spark in welding process, in inflammable and explosive place and hard soil layer be difficult to implement.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of petroleum works Special grounding device simple in structure, reasonable in design is provided, and is applicable to soil property hard area, is convenient to installing/dismounting.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of petroleum works Special grounding device, comprise the body of rod, it is characterized in that: body of rod top is provided with connection bump, the bottom is taper, body of rod side is provided with continuous thread groove, is provided with link slot connected vertically between thread groove, is provided with bonding jumper in thread groove and link slot, the picking up the ears of bonding jumper end and the body of rod is connected, and picks up the ears to be provided with screw hole.
The beneficial effects of the utility model are: the connection bump at body of rod top is fit to connection equipment, easy to use, be equipped with the bonding jumper that communicates in the thread groove of body of rod side and link slot, if wearing and tearing or fracture appear in the bonding jumper in installation process in thread groove, bonding jumper in link slot can replace its effect, the body of rod is worked on, improved it and used coefficient of safety, the connection of picking up the ears to be convenient to that the top is provided with.
