Abstract
The utility model relates to a 10kV grounding rod which is widely used in the reconstruction of a rural power network. The lower part of the 10kV grounding rod is provided with a spiral thread. The top end of the 10kV grounding rod is welded with a handle frame. Two sides of the handle frame are respectively installed with a handle. The upper part of the spiral thread is welded with a grounding wire connecting plate which is provided with a connecting hole. The grounding rod can be easily screwed into or out of the earth. The 10kV grounding rod has the advantages of easy operation, reliable contact, hard material, safety and reliability, and the working intensity of an operator is greatly reduced. The production cost of a single ground rod is about 90 RMB, the manufacture is simple, the practical problems in the work are solved, and a guarantee is provided for the safe production.
Description
Technical field
The utility model relates to a kind of power system operation instrument, relates in particular to a kind of 10kV earth rod, is widely used in the upgrading of rural power grids.
Background technology
Traditional earth rod is constructed or when running into harder soil in the winter time, often because self insufficient strength of earth rod causes earth rod in pounding underground process, is not to pound motionlessly, causes earth rod bending, damage exactly.Explicitly call for earth electrode inaccurate less than 0.6m in the subsurface degree of depth in the safety, therefore, even earth rod is pounded into underground reluctantly, reach the safety requirement, remove in the earth connection process in the end of job, the phenomenon that earth rod also often has the difficulty of taking out and can't take out is incured loss through delay electric power feeding time.
Summary of the invention
The utility model, improves on the basis of existing structure at above-mentioned problems of the prior art, a kind of 10kV earth rod is provided, the problem of constructional difficulties when having solved earth rod in the prior art in the winter time or having run into hard soil.
The technical solution of the utility model is as follows:
The bottom of body arranges the helical form screw thread, the top welding handle rack of body, and the handle rack both sides are mounting knob respectively; The top welding ground connecting plate of body helical form screw thread, the ground wire connecting plate is provided with connecting hole.
Described helical form screw thread is arranged on the body lower end to the 65cm place.
Described body lower end is most advanced and sophisticated.
Described handle is collapsible handle.
Described external surface is provided with zinc-plated anticorrosive coat.
It is diameter 20mm that described body adopts specification, No. 45 Fine Steel Casting irons.
The utility model has the advantages of as follows:
1, select No. 45 Fine Steel Casting irons to replace original material, increase the spiral screw thread on the metal body that earth rod is original smooth, collapsible handle is installed in the earth rod upper end, and the rotation earth rod just can screw in earth rod or screw out the earth easily.
2, easy to operate, contact firm, material is hard, has alleviated operating personnel's working strength greatly, and is safe and reliable.
3, single cost of manufacture is made simply about 90 yuan, has solved the practical problem in the work, for safety in production provides guarantee.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1, body, 2, screw thread, 3, handle rack, 4, handle, 5, the ground wire connecting plate.
Embodiment
Embodiment
As shown in Figure 1, it is diameter 20mm that body 1 adopts specification, No. 45 Fine Steel Casting irons.The lower end of body 1 goes out helical form screw thread 2 to the 65cm place with the lathe car, the lower end sharpening, and the top welding handle rack 3 of body 1, handle rack 3 is 12 * 3cm steel tank, and 4 one of collapsible handles respectively are installed in the handle rack both sides, handle 4 is diameter 20mm, long 25cm steel pipe; The ground wire connecting plate is provided with 4 of diameter 10mm circular holes to one of 7 * 7 band iron of top welding of body 1 as ground wire connecting plate 5, is used for connecting ground wire.
For improving hardness, quench in the earth rod tip, and the back hardness of quenching reaches HRC55, and the whole zinc-plated preservative treatment of doing of earth rod marks with color at the 65cm place.
When earth rod uses, the tip, lower end over the ground, end user's both hands are held handle, turn clockwise, and earth rod are rotated into underground, as to meet obstructions be that available sledgehammer knocks the top, and earth rod is continued to underground, reaches the 60cm requirement.
