Abstract
The utility model discloses a grounding nail which comprises a nail body. The lower end of the nail body is in a wedge shape; a wiring post is arranged on the side wall of the nail body, close to the top end; and a nail cap with a cross section greater than a cross section of the nail body is further arranged at the top end of the nail body. The grounding nail is simply structured; the arrangement of the nail cap can play a good role of protecting the wiring post; therefore, the grounding nail is effectively prevented from being damaged due to improper hammering in the mounting process; and the cost of constructing a power grid is further reduced.
Description
Technical field
The utility model relates to a kind of earthing device in the electric power system, particularly a kind ofly can electric current be imported underground grounding nail.
Background technology
Develop rapidly along with power grid construction; It must be more and more widely that earthing device is used as the protective device of electric power system; Its kind also is various unusually, but no matter how to change, and the most important functions of earthing device is still when electric power system is broken down; Importing is underground rapidly with electric current, to guarantee the safety of surrounding environment.Grounding nail is a kind of as earthing device, and is simple in structure because of it, the favor that obtains people easy to carry, and it also is the most general using.Present grounding nail mainly comprises nail body and the binding post that is connected on the nail body sidewall, and the lower end of nail body is the cusp-shaped setting, is convenient to install, and binding post then is to be used for being connected with earth connection.When this grounding nail simple in structure uses, at first earth connection is connected on the binding post securely, uses the top of the direct hammering nail of hammer body then, underground so that grounding nail is wedged.But in the actual installation process; Because be manual operation all, hammer falls through unavoidably, and when hammer falls through; That is to say when the hammer hammering drops on the binding post of grounding nail sidewall less than the top of grounding nail; Very easily binding post is damaged, and binding post damage in a single day just can not reuse, thereby cause the significant wastage of grounding nail.
The utility model content
The utility model technical issues that need to address provide a kind of grounding nail of new structure, can effectively prevent in installation process, to damage the generation of binding post phenomenon, thereby reduce the power grid construction cost.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of grounding nail comprises the nail body, and the lower end of nail body is a wedge shape, and the nail body is provided with binding post near the sidewall on top, and the top of said nail body is provided with the head of a nail of cross section greater than nail body cross section.
The concrete structure of the said head of a nail of the utility model is for to be: the shape of cross section of the said head of a nail is any one in circle, ellipse, regular polygon or the irregular figure.
The improvement of the utility model is: the importing angle between said binding post and the nail body is 0～180 degree.
The concrete structure of the said binding post of the utility model is: the band iron of said binding post for being fixedly connected with the nail body offers wiring hole on the band iron.
The another kind of structure of the said binding post of the utility model is: the double-screw bolt of said binding post for being fixedly connected with the nail body.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
The utility model is simple in structure, and the setting of the head of a nail can pairs of posts play a very good protection, and effectively avoids in the grounding nail installation process, causes the generation of grounding nail damage phenomenon owing to hammering is improper, further reduces the cost of power grid construction.Importing angle between binding post of the utility model and the nail body is set to 0～180 degree, insert in different angles to be fit to different earth connections, and it is more little to work as the angle that imports the angle, and resistance will be more little when grounding nail was installed, and installs with regard to Vietnamese side just.And angle is more little, and hammering into the vibration that ground produces in the process ground connection will be more little, make between grounding nail and the soil combine just tightr, thereby increase the flow area that looses, earth current is discharged rapidly.

Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation of embodiment 2;
Fig. 4 is the vertical view of Fig. 3.
Wherein: 1. nail body, the 2. head of a nail, 3. band iron, 31. wiring holes, 4. double-screw bolt, 5. importing angle.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details:
A kind of grounding nail, its structure is as depicted in figs. 1 and 2.
The head of a nail is fixedly connected on the top of nail body, and the head of a nail also can be one-shot forming with the nail body.The cross section of the head of a nail is circular, and its cross-sectional area is the twice of nail body cross-sectional area.
Binding post is a band iron 3, offers two wiring holes 31 on the band iron, is used for being connected with earth connection.Band iron directly is welded on the sidewall of nail body, and the importing angle between band iron and the nail body is 60 degree.
When present embodiment is installed, the direct hammering head of a nail, the head of a nail is simultaneously stressed with the nail body, and the nail body directly gets in the soil i.e. installation.
Present embodiment such as Fig. 3 and shown in Figure 4, be with the difference of embodiment 1: the cross section of the head of a nail is a regular hexagon.Binding post is that two double-screw bolt that is set up in parallel 4, two double-screw bolts vertically are set up in parallel, and vertical each other with the nail body, and double-screw bolt is threaded with following closely between the body, and earth connection directly is fixedly connected on the double-screw bolt.
Claims (5)
1. a grounding nail comprises nail body (1), and the lower end of nail body is a wedge shape, and the nail body is provided with binding post near the sidewall on top, it is characterized in that: the top of said nail body is provided with the head of a nail (2) of cross section greater than nail body cross section.
2. grounding nail according to claim 1 is characterized in that: the shape of cross section of the said head of a nail is any one in circle, ellipse, regular polygon or the irregular figure.
3. grounding nail according to claim 1 is characterized in that: the importing angle (5) between said binding post and the nail body is 0～180 degree.
4. grounding nail according to claim 3 is characterized in that: the band iron (3) of said binding post for being fixedly connected with the nail body offers wiring hole (31) on the band iron.
