Abstract
Spiral ground rod, including the barred body, the top of barred body is provided with through -hole, characterized by: the bottom of barred body is the cone point, and the top of cone point is the screw thread section, and the top of barred body is provided with vertical dog, and the lateral surface of dog is provided with spherical pit, still include the lantern ring that an insulating material made, be provided with on the inner wall of the lantern ring with be used for card income through spring coupling no. 1 in the dog complex draw -in groove, draw -in groove pellet part in the spherical pit of dog, the barre that the rigid coupling has insulating material to make is gone back in the lantern ring outside. It is swiftly laborsaving that this earth bar inserts ground, and convenient and fast too when extracting moreover saves operating time.
Description
Technical field
The utility model relates to the earth rod that a kind of grounding wire of power system connects.
Background technology
Power circuit power failure operation first must carry out electrical verification, ground connection, and ground connection must use earth connection.The earth rod of common earth connection is made up of the reinforcing bar of one 80 centimeters long, and a tip is beneficial to inserts ground, and a headband has bolt connecting hole, is connected with earth connection.But this earth rod, in the process inserting ground, expend very large strength, and upper end does not have impetus, works together harder.The time that earth rod on average inserts ground is 5 minutes.
Utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of spiral earth rod, and this earth rod inserts ground convenient power-saving, and convenient and swift too when extracting, and saves the operating time.
In order to solve the problem, the utility model is by the following technical solutions: spiral earth rod, comprise barred body, the top of barred body is provided with through hole, it is characterized in that: the tapered tip, bottom of described barred body, the top of cone point is thread segment, and the top of barred body is provided with vertical block, and the lateral surface of block is provided with spherical pit;
Also comprising the collar that an insulating material is made, the inwall of the collar is provided with the draw-in groove coordinated with described block, in draw-in groove, connecting one for snapping in the pellet part in the spherical pit of described block by spring;
The barre that insulating material is made also is connected with outside the collar.
Preferably, the length of described thread segment is not less than 30cm, and the pitch of thread segment is 2-3cm.
Preferred: described vertical block is provided with two, the symmetrical both sides being positioned at barred body; Draw-in groove on collar inwall is also provided with two accordingly.
Preferred: described draw-in groove is made up of the two pieces of baffle plates be parallel to each other.
Preferred: described barre is horizontal cross bar, and barre is provided with two, is symmetrically distributed in the both sides of the collar.
The beneficial effects of the utility model are: this earth rod inserts ground convenient power-saving, and convenient and swift too when extracting, and save the operating time.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1;
In figure: 1 barred body, 2 through holes, 3 cone points, 4 thread segments, 5 blocks, 51 spherical pits, 6 collars, 7 draw-in grooves, 8 springs, 9 spherical members, 10 barres.
Embodiment
As shown in Figure 1, 2, this spiral earth rod, comprises barred body 1, the top of barred body 1 is provided with through hole 2, the bottom tapered most advanced and sophisticated 3 of described barred body 1, and the top of cone point 3 is thread segment 4, the top of barred body 1 is provided with vertical block 5, and the lateral surface of block 5 is provided with spherical pit 51.
This spiral earth rod also comprises the collar 6 that an insulating material is made, and the inwall of the collar 6 is provided with the draw-in groove 7 coordinated with described block 5, connects one for snapping in the pellet part 9 in the spherical pit 51 of described block in draw-in groove 7 by spring 8.
The barre 10 that insulating material is made also is connected with outside the collar 6.
In this embodiment, the length L of described thread segment is 30cm, and the pitch of thread segment is 2cm.As other execution modes, the length L of thread segment be not less than 30cm any one point value can, pitch be any one point value between 2-3cm also can, comprise 3cm.No longer enumerate at this.The length of thread segment more long being more conducive to firmly fixes on the ground, and pitch greatly can fast drilling, but encounters hard ground and be then applicable to the slightly little barred body of pitch.
In this embodiment: described vertical block 5 is provided with two, the symmetrical both sides being positioned at barred body 1; Draw-in groove 7 on the collar 6 inwall is also provided with two accordingly.More Labor-saving high-efficiency when rotating barred body.
Further, described draw-in groove 7 is made up of the two pieces of baffle plates 71 be parallel to each other.This spline structure is simple, and cost easy to process is low.
Further: described barre 10 is horizontal cross bar, and barre 10 is provided with two, is symmetrically distributed in the both sides of the collar 6.So convenient symmetrical applying strength, ensures vertically to creep into; And operation is more reliably not easy to lose efficacy.
This earth rod is when inserting ground, and be first nested with on barred body by the collar, make draw-in groove 7 be stuck on block 5, when draw-in groove 7 drops to certain position, pellet part 9 snaps in spherical pit 51, and the collar 6 no longer declines, and the upper-lower position of the collar 6 is defined.Then both hands hold barre 10, rotational lantern ring, and the collar drives barred body to rotate by draw-in groove, block, and the bottom of barred body pierces ground.Because barre 10 is set to two even more, so rotation is convenient especially, barred body 1 can be made to pierce ground fast.
After having pierced, the collar is taken off, then by earth connection and earth rod being connected by through hole and connector.
The method that earth rod extracts ground is identical, just rotates backward.No longer describe in detail.
Above-described embodiment is only the utility model preferred embodiment, and not representing protection range of the present utility model is only above-mentioned execution mode.
