Abstract
The utility model discloses a grounding pile for power equipment, comprising a pile body, wherein the pile body is a cylindrical pile body with an inner cavity; the outer wall of the pile body is provided with barbs; the lower end of the pile body is provided with two fixed plates; one end of each fixed plate is hinged at the lower end of the pile body by a first pin shaft, and the other ends of the two fixed plates are hinged together by a second pin shaft; the pile body is internally provided with a blocking piece with a screw hole at the middle part; and a screw with a screw cap penetrates through the blocking piece to be connected on the second pin shaft. The grounding pile adopting the structure has the advantages that the construction is convenient, the pile body is easily smashed into the ground, the contact area between the grounding pile and the underground soil is enlarged, and simultaneously the purpose of firmly combining the grounding pile and the underground soil is achieved, so that the pulling resistance of the grounding pile is increased and the antitheft effect is good.
Description
Technical field
The utility model belongs to the power equipment servicing unit, particularly relates to a kind of ground stud that is used for power equipment.
Background technology
Electric power transmission line and relevant device all are built among Plain, hills, the wilderness, chain of mountains area, are exposed under the atmospheric environment, are struck by lightning easily, because the situation of the line tripping that thunderbolt causes often takes place.For anti-thunderbolt, need earthing device be installed to transmission line.The purpose of earthing device is exactly to make the lightning current that acts on the lead introduce the earth along down conductor through earth electrode as soon as possible, avoids line facilities such as lead, insulator to suffer superpotential infringement.Earthing device needs reliable ground connection, adopts the ground stud of metal quality usually.Ground stud is to squeeze into ground through external force; But because power transmission sequence resident's legal consciousness faint along the line; It is not enough to receive interests to order about and have now the earthing device withdrawal resistance, causes the stolen situation of earthing device to happen occasionally, and brings unsafe factor for the operation of circuit; And stolen ground stud need be laid equal stress on the new clothes by maintainer's periodic inspection, makes maintenance cost high.
Therefore, it is firm to design a kind of ground stud and ground engagement, and the ground stud that is used for power equipment that is not drawn out easily is the technical problem that those skilled in the art need solution badly.
The utility model content
For overcoming the deficiency that above-mentioned similar technology exists, the purpose of the utility model provides a kind of ground stud that is used for power equipment.
The technical scheme of the utility model is:
A kind of ground stud that is used for power equipment comprises pile body, and said pile body is the inner cylindrical pile body of cavity that is; The outer wall of said pile body is provided with hangnail; Said pile body lower end is provided with two, and said two fixed head one ends are hinged on the pile body lower end through first bearing pin with deciding plate, and the other end of said two fixed heads is hinged through second bearing pin; The catch that to be provided with a middle part in the said pile body be screw, the screw rod of a band nut passes catch and is connected on second bearing pin.
As optimized technical scheme, the said pile body upper end of the utility model is provided with plug.
As optimized technical scheme, be connected through socket or the mode that is spirally connected between the said plug of the utility model and the pile body.
As optimized technical scheme, the said hangnail and the pile body of the utility model are one-body molded.
As optimized technical scheme, the said hangnail of the utility model is evenly to be provided with more than two and around pile body surface.
The beneficial effect of the utility model is:
The utility model is compared with prior art, and its effect is actively with tangible.The utility model is provided with in stake power ground can be through the fixed head of screw rod operation, and fixed head is connected with the ground stud lower end through bearing pin, when the nut on the rotary screw; Screw rod rises; Can make two fixed dams be level or near horizontal state, make itself and ground engagement area, make that resistance increases when pulling out ground stud greater than the cross section of ground stud; Prevent that effectively ground stud from being extracted by unauthorized person, guaranteed the safe operation of power circuit.
In addition, the setting of hangnail has also increased the contact area of ground stud and underground, has reached the purpose that combines between dead earthing stake and underground ground soil simultaneously, has therefore increased the withdrawal resistance of ground stud.
The utility model is simple in structure, fixation, and withdrawal resistance is strong, good anti-theft effect.Thereby significantly reduced maintenance labour intensity, practiced thrift recondition expense, made circuit safe and reliable to operation, solved the deficiency that prior art exists.

Embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to accompanying drawing 1; Propose a specific embodiment of the utility model, a kind of ground stud that is used for power equipment comprises pile body 1; Said pile body 1 is the inner cylindrical pile body of cavity that is; The outer wall of said pile body 1 is provided with hangnail 2, and said hangnail 2 is one-body molded with pile body 1, and said hangnail 2 is evenly to be provided with more than two and around pile body 1 surface.Hangnail the contact area that has increased ground stud and underground is set, reached the purpose that combines between dead earthing stake and underground ground soil simultaneously, therefore increased the withdrawal resistance of ground stud.
Said pile body 1 upper end is provided with plug 8.Be connected through socket or the mode that is spirally connected between said plug 8 and the pile body 1.
Said pile body 1 lower end is provided with two fixed heads 3; Said two fixed head 3 one ends are hinged on the lower end of pile body 1 through first bearing pin 4; The other end of said two fixed heads 3 is hinged through second bearing pin 5; The screw rod 7 of catch 6, the one band nuts that to be provided with a middle part in the said pile body 1 be screw passes catch 6 and is connected on second bearing pin 5.
During use, on plug is not stifled, ground stud knocked in ground after, through the sleeve rotary screw, two fixed heads are set level, knock in plug again, in case unauthorized person takes out ground stud.
The above is merely the preferred embodiment of the utility model; Be not therefore and the claim of restriction the utility model; Every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
