Abstract
The utility model relates to a ground wire ground stud comprising a ground wire head, a grounding seat, an adaptor and a butterfly nut. The grounding seat is provided with an external thread bush; the external thread bush and the grounding seat form an integrated one. An internal thread is formed in the adapter and cooperates with the external thread bush of the grounding seat. A ground wire insertion hole is formed in the ground stud; after the ground wire head is inserted into the hole, the step of the ground wire head is contacted with the end surface of the external thread bush of the ground stud. The bufferfly nut with an external thread is screwed into the adapter with the internal thread and the step of the ground wire head is pressed to realize close connection with the ground stud, thereby achieving an objective of grounding. According to the scheme, cooperation of the adapter and the ground stud is designed. When the ground wire head is assembled or disassembled frequently, only the adapter is exposed and cooperates with the butterfly nut for rotation, thereby protecting the ground stud. After the thread is rusted and worn, only the adapter needs to be replaced directly, so that the service life of the ground stud is not influenced and the maintenance becomes convenient; and thus the ground reliability and security of the ground stud are further improved.
Description
Technical field
The application relates to a kind of ground wire grounded stake, and it is applied to power industry, particularly relates to a kind of ground wire grounded stake that is applied in transformer station, power plant, petrochemical industry, metallurgy, coal etc., can be used in conjunction with other blocking mechanism.
Background technology
When high-tension apparatus repair and maintenance, need be to the ground connection of maintenance of equipment or circuit, thus ensure operating personnel's personal safety and the safety of equipment, therefore, it is extremely important that ground wire grounded reliability just becomes.
Conventionally earthing device is made up of jointly blocking mechanism and earth wire pile, then earth wire pile is welded on the earthing conductor of place or equipment, the on-the-spot earth wire pile using is made up of grounding base and the grounding copper nut being welded on grounding base, described grounding copper nut is external screw thread structure, when use, ground wire is inserted to ground stud, on ground wire with wing nut be screwed on the copper nut of grounding base, thereby complete the task of articulating earth connection.
External screw thread friction on internal thread on wing nut and grounding copper nut is frequent, cause thread abrasion to fluff, in addition, external screw thread on grounding copper nut is not in the time using in another straight exposure air, especially pass through the rainwater of rainwater or hybrid corrosion gas, cause the screw thread seriously corroded on partial earthing copper nut, above-mentioned multiple phenomenon finally causes ground connection bad, have a strong impact on earthing effect, operating personnel's personal safety has been caused to hidden trouble.While maintenance, need change whole earth wire pile, maintenance cost is high.
Summary of the invention
The utility model discloses a kind of ground wire grounded stake, this ground wire ground stud is provided with adaptor protective device, has effectively solved earth wire pile fragile, safeguards inconvenient problem.
The utility model takes following technical scheme to realize:
A ground wire grounded stake, comprises ground wire, grounding base, adaptor and wing nut; Wherein said grounding base is provided with external thread sleeve, described external thread sleeve and grounding base form an entirety, described adaptor is provided with internal thread, described wing nut is with external screw thread, one end of described adaptor coordinates with the external thread sleeve on grounding base, the other end coordinates with the external screw thread of described wing nut, and earth wire pile is provided with ground wire patchhole.
In the utility model, the ground wire patchhole of earth wire pile is used for inserting ground wire, and the end face of the step of patchhole and earth wire pile external thread sleeve fits.To be provided with externally threaded screw-in and establish in female adaptor, the step of pushing down ground wire makes it closely be connected with earth wire pile, reaches the object of ground connection.
According to the utility model, the two ends of described adaptor are all provided with internal thread.The length of its internal thread is enough to coordinate with the external screw thread of external thread sleeve or wing nut.
According to the utility model, in the through hole of described adaptor, be all provided with internal thread.
Feature of the present utility model is: designed adaptor and coordinated with earth wire pile; in the time of the frequent dismounting of ground wire; just adaptor is exposed to the outer turn generation friction that coordinates with wing nut; earth wire pile is played a protective role; screw thread is directly changed adaptor after getting rusty and wearing and tearing, effectively ensured the reliability of ground connection.
Brief description of the drawings
Accompanying drawing 1 is the utility model electric wire ground stud internal structure profile.
Wherein the implication of each Reference numeral is as follows:
1 ground wire, 2 grounding bases, 3 adaptors, 4 wing nuts, 21 external thread sleeves
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail, but those skilled in the art's understanding, following real-time mode is not limiting the scope of the invention, any improvement of making on basis of the present invention and variation, all within protection scope of the present invention.
As shown in Figure 1, be the ground wire grounded pilework profile of the utility model, a kind of ground wire grounded stake, comprises ground wire 1, grounding base 2, adaptor 3 and wing nut 4; Wherein grounding base is provided with external thread sleeve 21 and forms an entirety with grounding base, adaptor 3 is provided with internal thread, coordinate with the external thread sleeve 21 of grounding base 2, earth wire pile is provided with ground wire 1 patchhole, the end face that ground wire 1 inserts backward step and earth wire pile external thread sleeve 21 fits, to be provided with externally threaded wing nut 4 screw-ins and establish in female adaptor 3, the step of pushing down ground wire 1 makes it closely be connected with earth wire pile, reaches the object of ground connection.
Claims (3)
