Abstract
The utility model discloses a kind of spiral test earthing poles, including earthing pole shaft end, double handles, test drainage thread fixed area and spiral steel pipe；Earthing pole shaft end middle part is horizontally arranged with perforation, lower part fixed setting test drainage thread fixed area, it tests on the outer circumference surface of drainage thread fixed area and is provided with threaded area, double handles are fixed on earthing pole shaft end by perforation, and the upper end for testing drainage thread fixed area lower end and spiral steel pipe is fixedly welded.The utility model grounding electrode whole installation is spiral helicine structure, and handle is arranged in portion on the electrode, to make the unearthed when entering ground or remove of electrode that can rotate progress, simultaneously rotating part be also used as electric current pole, voltage pole decanting point drill rod and the earth in soil be in close contact, make full use of grounding test apparatus test electric current, and risk when existing electrode is rammed cylindrical type drill rod progress electric current pole, the installation of voltage pole decanting point or removed using iron hammer is substantially reduced, improve working efficiency.
Description
Technical field
The utility model relates to test earthing pole technical field, more particularly to a kind of spiral test earthing pole.
Background technique
Qualified earthing or grounding means has a very important role in safe operation of power system.Substation's O&M overhauls people
Member carries out the electric parameter performance test of substation grounding device according to the time between overhauls(TBO), to judge the good of substation grounding unit state
It is bad.When test, tester generally will use several cylindrical type drill rods as choose electric current pole, voltage pole decanting point, and two
People is rammed into soil layer with the use of iron hammer, then test drainage thread is fixed on these cylindrical type drill rods, test data
Superiority and inferiority will largely depend on these electric current poles, voltage pole decanting point (i.e. cylindrical type drill rod) is rammed into the quality of quality, such as
Fruit hammer during drill rod is rammed into is inclined, and may result between drill rod and soil has larger air void, electric current pole, voltage
Pole decanting point cannot influence to test disseminating for electric current with greatly combining closely.In addition, when being rammed into using iron hammer or extracting drill rod
At least two people are needed skillfully to cooperate, time-consuming and laborious there are also certain risk, and drill rod is extracted after test, and there is still a need for expend very
More energy, very influence working efficiency.
Utility model content
The purpose of the utility model is to provide a kind of spiral test earthing poles, to avoid iron hammer from being rammed into traditional cylinder type steel
There are larger the air gaps between electric current pole, voltage pole and soil that pricker may cause, to make as electric current pole, voltage pole decanting point
Drill rod and the earth in soil be in close contact, make full use of grounding test apparatus test electric current, and reduce and rammed using iron hammer
Risk when cylindrical type drill rod carries out electric current pole, the installation of voltage pole decanting point or removes, improves working efficiency.
The utility model adopts the following technical solutions:
A kind of spiral test earthing pole, being fallen down from above successively includes earthing pole shaft end 2, double handles 3, test drainage thread
Fixed area 4 and spiral steel pipe 5；2 middle part of earthing pole shaft end is horizontally arranged with perforation, lower part fixed setting test drainage
Line fixed area 4 is tested on the outer circumference surface of drainage thread fixed area 4 and is provided with threaded area, and double handles 3 pass through perforation
It is fixed on earthing pole shaft end 2, the upper end of 4 lower end of test drainage thread fixed area and spiral steel pipe 5 is fixedly welded.
Described spiral test earthing pole generally high strength steel material.
3 radius of turn of double handles is 15~20cm.
The test drainage thread fixed area 4 is fastened for experimental test drainage thread.Test drainage thread is solid: determining area
4 be threaded area, is processed on 2 surface of earthing pole shaft end.
5 bottom of spiral steel pipe is cone point, is convenient for when installing and using into ground.
The utility model is spiral helicine structure grounding electrode whole installation, and handle is arranged in portion on the electrode, is used for
Rotation, so that electrode be made to enter ground or be unearthed when removing can to rotate progress, while rotating part be also used as electric current pole,
Soil is in close contact in the drill rod and the earth of voltage pole decanting point, makes full use of grounding test apparatus test electric current, and significantly
Reduce danger when existing electrode is rammed cylindrical type drill rod progress electric current pole, the installation of voltage pole decanting point or removed using iron hammer
Property, improve working efficiency.
Detailed description of the invention
Fig. 1 is the structural principle block diagram of the utility model.
Specific embodiment
As shown in Figure 1, it successively includes earthing pole shaft end 2, double handles 3, test drainage thread that the utility model is fallen down from above
Fixed area 4 and spiral steel pipe 5；2 middle part of earthing pole shaft end is horizontally arranged with perforation, lower part fixed setting test drainage
Line fixed area 4 is tested on the outer circumference surface of drainage thread fixed area 4 and is provided with threaded area, and double handles 3 are solid by perforation
It is scheduled on earthing pole shaft end 2, the upper end of 4 lower end of test drainage thread fixed area and spiral steel pipe 5 is fixedly welded.
Described spiral test earthing pole generally high strength steel material.
3 radius of turn of double handles is 15~20cm.Handle length is moderate, unsuitable too short or too long, Jin Erying
Ring manpower using effect.
The test drainage thread fixed area 4 is fastened for experimental test drainage thread.Test drainage thread is solid: determining area
4 be threaded area, is processed on 2 surface of earthing pole shaft end.
5 bottom of spiral steel pipe is cone point 1, and the setting of cone point 1 is convenient for the utility model when installing and using
Enter ground.The earthing pole shaft end 2 securely welds together with spiral steel pipe 5.When the utility model is used, staff is revolved
Turning double handles 3 drives earthing pole shaft end 2 to rotate clockwise, and earthing pole shaft end 2 then drives spiral steel pipe 5 to rotate, and can facilitate
It screws in soil, completes the installation of electric current pole, voltage pole decanting point, and make electric current pole, soil in voltage pole decanting point and the earth
It is in close contact.To ensure that the earthing effect of electrode；When needing to remove electric current pole, voltage pole decanting point after completing test,
It only needs to rotate counterclockwise double handles 3 and exits spiral test earthing pole 1.Use process single can be completed, Wu Xutie
Hammer, safe and reliable, convenient, flexible, while protective grounding pole, more convenient dismount, and significantly improves work
Efficiency, practical are very strong.
