Abstract
The utility model relates to a grounding pile for power equipment. A grounding pile body is hollow; the lower end of the grounding pile body is connected with two Z-shaped plate pieces by pin shafts; the two plate pieces are symmetrically arranged in the grounding pile body; the lengths of the upper ends of the two plate pieces are less than the width of the grounding pile body; the upper end of one plate piece is U-shaped; the width of the U-shaped middle opening is more than that of the upper end of another plate piece; and the lower ends of the two plate pieces are in tip shapes with large upper parts and small lower parts. In the grounding pile for the power equipment, the two Z-shaped plate pieces are arranged by the pin shafts, the normal states of two plate pieces are in vertical states, when the grounding pile is hammered, two plate pieces also enter the ground, and extend into the grounding pile body by a rod piece for hammering, so that the two Z-shaped plate pieces rotate to be horizontal or be almost horizontal, the areas of the jointing surfaces of the two Z-shaped plate pieces and the ground are larger than that of the cross section of the grounding pile, the resistance is increased when the grounding pile is pulled, the grounding pile is effectively prevented from being pulled illegally, and further safe operation of a power line is guaranteed.
Description
Technical field
The utility model relates to the power equipment servicing unit, and particularly the safety guard of electric power transmission line and equipment specifically is a kind of ground stud that is used for power equipment.
Background technology
Are struck by lightning easily in outdoor in electric power transmission line and relevant device many places, because the situation of the line tripping that thunderbolt causes often takes place.For anti-lightning strike, need earthing device be installed to transmission line, the current steering that produces being struck by lightning avoids lead or transmission facility to be subjected to the infringement of lightning voltage to the earth.Earthing device needs reliable ground connection, adopts the ground stud of metal quality usually.Ground stud is to squeeze into ground by the external force hammering, but, the stolen situation of ground stud is often arranged, the unsafe factor that the operation of line circuit brings because the ground stud capacity is pulled out, and stolen ground stud need be laid equal stress on the new clothes by maintainer's periodic inspection, makes the maintenance cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of stake power ground, and ground stud and ground engagement that described this stake power ground will solve the ground protection that is used in the power circuit in the prior art are not firm, the technical problem that capacity is extracted.
The purpose of this utility model is achieved through the following technical solutions: comprise the ground stud body, the ground stud body is hollow form, connect two in ground stud body lower end by bearing pin and be the zigzag plate, these two plates are located in the ground connection pile body symmetrically, the length of the upper end of these two plates is less than the width of ground stud body, the upper end of an one plate takes the shape of the letter U, and the width of the middle opening of this U-shaped is greater than the width of another plate upper end, the tip shape that the lower end of these two plates is big up and small down.
When two plates were vertical, its lower end was vertical shape, its upper end all tilts to the center line of ground stud body.
Be provided with plug in ground stud body upper end.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model is provided with two at the ground stud that is used for power equipment by bearing pin and is the zigzag plate, these two plate normal conditions are to be vertical state, when the hammering ground stud, two plates also enter ground, stretch into to knock in the ground connection pile body by a rod member and make two zigzag plates rotate to level or near level, make itself and ground engagement area cross section greater than ground stud, make that resistance increases when pulling out ground stud, prevent that effectively ground stud from being extracted by unauthorized person, guaranteed the safe operation of power circuit.

Schematic diagram when Fig. 2 is the use of the ground stud that is used for power equipment of the present utility model.
Fig. 3 is the schematic diagram of a plate of the present utility model.
Fig. 4 is the schematic diagram of another plate of the present utility model.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the utility model is used for the ground stud of power equipment, comprise ground stud body 1, ground stud body 1 is hollow form, connect two in ground stud body 1 lower end by bearing pin 5 and be zigzag plate 2,3, these two plates 2,3 are located in the ground connection pile body 1 symmetrically, these two plates 2, the length of 3 upper end is less than the width of ground stud body 1, so that its rotation, the upper end of an one plate 2 takes the shape of the letter U, the width of the middle opening of this U-shaped is greater than the width of another plate 3 upper ends, these two plates 2, the tip shape that 3 lower end is big up and small down.When two plates were vertical, its lower end was vertical shape, its upper end all tilts to the center line of ground stud body 1, when hammering plate upper end, made the plate rotation easily like this.Be provided with plug 4 in ground stud body 1 upper end.
During use, when the hammering ground stud, two plates also enter ground, stretch into to knock in the ground connection pile body by a rod member and make two zigzag plates rotate to level or near level, this moment, the upper end of its another plate entered in the U-shaped opening of a plate upper end, made two plates and the ground engagement area cross section greater than ground stud, made that resistance increases when pulling out ground stud, prevent that effectively ground stud from being extracted by unauthorized person, guaranteed the safe operation of power circuit.
Claims (3)
1. ground stud that is used for power equipment, comprise the ground stud body, it is characterized in that: the ground stud body is hollow form, connect two in ground stud body lower end by bearing pin and be the zigzag plate, these two plates are located in the ground connection pile body symmetrically, and the length of the upper end of these two plates is less than the width of ground stud body, and the upper end of an one plate takes the shape of the letter U, the width of the middle opening of this U-shaped is greater than the width of another plate upper end, the tip shape that the lower end of these two plates is big up and small down.
