Background technique
With the continuous growth of our country's economy, the demand of electric power is also increasing, and some equipment occur since runing time is long
Aging, deformation, situations such as being even broken, need us operation maintenance personnel to check replacement in time.Especially in route annual overhaul
When, special examination is carried out to pole tower ground wires fittings such as large crossing span, big height difference, important scissors crossings.Existing grounding rod is
It is made of an insulating bar and ground line, when carrying out the operation of ground wire, grounding rod and multiply annealed copper wire is separated, first installed
Ground terminal has installed energized conductor end finally by insulating bar.Wherein installation energized conductor end is using flat and hedgehog hydnum formula gold
Belong to device, intermediate plate is tightened by rotating insulated stick, makes intermediate plate and conductor reliable ground.
Aerial earth wire grounding rod used at present is relatively simple, for different voltages grade, different tower cannot be complete
It being applicable in, the ground wire hardware tool assembling string length of different towers is all different, and length is not adjustable, and it is not portable, it is difficult to install, it uses
It is also inconvenient to get up, very influence working efficiency.Tower operation is stepped in maintenance must use kit, and current used grounding rod is too
Long, kit can not load, and upper and lower tower, which is easy to happen, to collide with, and influences operating efficiency.It is also relatively difficult when installing grounding rod, due to length
Degree is insufficient, and steel tower larger for multiple-circuit on same tower etc. operates extremely difficult.In addition it in installing process, needs to twist
Insulating ground stick tightens its bolt, could reliable ground.When disassembly ground line, it is too short or to be placed in aerial grounding rod
It takes advantage of a situation downward through rotation direction, operating personnel cannot smoothly dismantle, it is necessary to it is reversed to suitable angle, can be dismantled,
It is more time-consuming.
Utility model content
In view of the deficiencies of the prior art, the utility model provides one kind and is convenient for carrying, and when attaching ground wire is simple to operate
Aerial earth wire Portable ground rod.
To achieve the above object, the technical solution of the utility model are as follows:
A kind of aerial earth wire Portable ground rod, including insulating bar and the ferrule for being located at insulating bar one end, the insulation
Stick is multilayer retractable structure, and the ferrule is U-shaped ferrule, and one end of the U-shaped ferrule is turned down to centre, and to U
The bottom of type ferrule is extended with extension, and distance is described exhausted not less than ground linear diameter between the extension and U-shaped ferrule
The innermost layer of edge stick is fixedly connected with extension, and the other end of the insulating bar is connected with safe hanging buckle.
Further, the U-shaped ferrule is equipped with trapezoidal fixture block, and the trapezoidal fixture block is oppositely arranged on U-shaped ferrule
Two sides inside and extension two sides.Make ground wire after sticking into U-shaped ferrule in this way, using trapezoidal fixture block with
The structure of U-shaped ferrule is clamped clamping, and ground wire is enabled to be not easily disconnected from the clamping control of insulating bar.
Further, electroscope is provided in the U-shaped ferrule.Ground wire can be detected using electroscope, when
When it is close to charged object, sound can be issued, and then can ensure that the insulating effect of this grounding rod.
The utility model compared with prior art, has the advantages that
By retractable structure, so that grounding rod is more convenient when carrying tower up and down, and length is adjustable, applicable
In various towers.The metal block that grounding rod is connect with energized conductor end uses " U-shaped formula ", enables its operation letter when installing ground line
It is single, by way of " one draws two to push away " can by energized conductor reliable ground, when disassembly sequence in contrast, and in insulating bar
End connects safe hanging buckle, can be fixed on insulating bar on tower material, prevents its skew of falling, and convenient working personnel dismantle ground connection
Line.

Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have
Body embodiment is described in further detail the utility model.
Embodiment
As shown in Figure 1, a kind of aerial earth wire Portable ground rod, including insulating bar 1 and the metal for being located at 1 one end of insulating bar
Head, insulating bar 1 are multilayer retractable structure, and ferrule is U-shaped ferrule 2, and one end of U-shaped ferrule 2 is turned down to centre, and to
The bottom of U-shaped ferrule 2 is extended with extension 21, and distance is not less than ground linear diameter between extension 21 and U-shaped ferrule 2, this
Vacancy between the U-shaped one end not turned down of ferrule 2 of sample and extension 21 forms ground wire entrance 24, the U-shaped fold of ferrule 2 one
End forms fixing end 25, and ground wire is made to run to fixing end 25 around its U-shaped ferrule 2, and the innermost layer of insulating bar 1 and extension 21 are solid
Fixed connection, the other end of insulating bar 1 are connected with safe hanging buckle 3.
As shown in Fig. 2, U-shaped ferrule 2 is equipped with trapezoidal fixture block 22, trapezoidal fixture block 22 is oppositely arranged on U-shaped ferrule 2
The inside on two sides and the two sides of extension 21, trapezoidal 22 material of fixture block are plastic material, there is certain deformability, so that
Ground wire, by deformation, enables ground wire be stuck at inner most space, is not easily disconnected from the clamping control of insulating bar 1 when sticking into
System.And the side in U-shaped ferrule 2, it is connected with electroscope 23.Ground wire is detected by electroscope 23, when its is close
When charged object, sound can be issued, and then can learn whether this grounding rod produces insulating effect.
When in use, first by safety rope hanging on the safe hanging buckle 3 of insulating bar 1, then staff carries and originally connects
Ground stick works, and when needed, is extended by the retractable structure using insulating bar 1, can cope with difference
Length work.When it is elongated to enough length, U-shaped ferrule 2 is crossed into ground wire first, ground wire is directed at its U
At 2 entrance 24 of type ferrule, grounding rod is then pulled, so that ground wire is crossed trapezoidal fixture block 22 and walks to U-shaped 2 bottom of ferrule, then push away
Dynamic grounding rod, makes ground wire cross trapezoidal fixture block 22 again, walks to fixing end 25, right using trapezoidal fixture block 22 and U-shaped ferrule 2
Ground wire is clamped, it is not easily disconnected from.Whole operation process is simple and convenient.
For above-described embodiment simply to illustrate that the technical ideas and features of the present invention, its purpose is allows this field
Interior those of ordinary skill can understand the content of the utility model and implement accordingly, can not limit the utility model with this
Protection scope.The equivalent changes or modifications that all essence according to the content of the present invention is made, should all cover in this reality
With in novel protection scope.
