Abstract
The utility model relates to an auxiliary device of a power line pole tower, in particular to a graphite grounding pole of a pole tower. The graphite grounding pole is characterized in that the main body of the grounding pole (1) consists of a cylindrical graphite block (2) and a metal connecting plate (3). The graphite grounding pole has the benefits that as the cylindrical graphite block is adopted, the surface area is large, the weight is light, the corrosion-resisting performance is good, the transportation is convenient, the soil excavation amount and the excavation area are reduced obviously, therefore, the graphite grounding pole has the advantages of simple structure, low manufacturing cost, reliable performance and the like, and avoids various defects of the existing steel wire grounding pole.
Description
Technical field
The utility model relates to a kind of electric power line pole tower auxiliary appliance, promptly a kind of shaft tower graphite earth electrode.
Background technology
Thunder and lightning destroys and the safety of construction for electric power line pole tower exempts from, and all earth electrode will be installed below the shaft tower.Present earth electrode all is to adopt steel wire to make.Because the steel wire self-resistance is bigger, surface area per unit length is less, so buried part must have enough length, has produced bigger steel wire freight volume and earthwork excavated volume thus, causes certain burden to construction.In addition, be subjected to condition restriction not allow large tracts of land to excavate in many construction sites, the application of existing steel wire earth electrode has run into difficulty.
Summary of the invention
It is all smaller with excavation area that the purpose of this utility model provides a kind of freight volume, earthwork excavated volume, install easier, the graphite earth electrode that good conductivity, cost are not high.
Above-mentioned purpose is realized by following technical scheme: developing a kind of shaft tower graphite earth electrode, also is to join and buried conductor part with shaft tower.Be characterized in: the main body of this earth electrode is that cylindricality graphite block and metal connecting plate constitute.During work, the cylindricality graphite block is imbedded underground, and be connected with shaft tower by the metal connecting plate.
Said graphite block is cylindrical, and two or more are one group, and the connecting plate between the graphite block is a steel plate, and steel plate links to each other with graphite by bolt, is connected with shaft tower again.
The diameter 260-340mm of said cylindrical graphite block, high 450-520mm is made up of four graphite blocks for every group, graphite block spacing 800-1200mm, between the wide 30-40mm of steel plate, link to each other by bolt, one links to each other with the earth terminal of shaft tower.
Said graphite block is round barrel shape.
The beneficial effects of the utility model are: owing to adopted cylindric graphite block, surface area is big, and is in light weight, be convenient to transportation, earth excavation amount and excavation area significantly descend, and have advantages such as simple in structure, cheap, dependable performance, have avoided the various disadvantages of existing steel wire earth electrode.

Among the figure as seen: graphite earth electrode 1, graphite block 2, connecting plate 3, bolt 4, shaft tower 5, earth terminal 6, ground 7.
Embodiment
First kind of embodiment: as shown in Figure 1, 2, this shaft tower graphite earth electrode 1 be by graphite block 2 and up and down the connecting plate 3 of both sides be formed by connecting by bolt 4.Wherein, graphite block 2 is cylindrical, diameter 260-340mm, high 450520mm, form by four graphite blocks 2 for every group, graphite block 2 spacing 800-1200mm, between connecting plate 3 adopt the steel plate of wide 30-40mm, a screw is arranged on each graphite block 2, have through hole on the steel plate, fixing by bolt 4.
Fig. 3 has represented the occupation mode of this earth electrode 1.Promptly this graphite earth electrode 1 is imbedded ground below 7.One links to each other with the earth terminal 6 of shaft tower 5.
Second kind of embodiment: as shown in Figure 4, this shaft tower graphite earth electrode 1 be by four cylindrical graphite blocks 2 and up and down the connecting plate 3 of both sides be formed by connecting by bolt 4.Different with precedent is that the steel plate here disconnects, and a steel plate is respectively arranged up and down between two graphite blocks.This mode is convenient to curved arrangement, can adapt to narrow place.
The third embodiment: as shown in Figure 5, the graphite block 2 of this shaft tower graphite earth electrode 1 is tubbiness, is characterized in having bigger surface area, and is in light weight, can save a large amount of graphite raw materials.Bucket can have the end, also can not have the end.Recommend to adopt the tubbiness graphite block 2 that the end is arranged.The opening of bucket can be up, also can be downward, all very big contact area is arranged with soil.Wherein bung up can be more storage moisture, strengthen electric conductivity.
The 4th kind of embodiment: as shown in Figure 6, the connecting plate between the graphite block 2 is replaced by metallic plate or metal wire, and by tying up connection.The connected mode of this example explanation graphite block 2 can be diversified.
