Abstract

The utility model discloses a screwing type ground rod. The screwing type ground rod comprises a ground rod body, a screw rod is fixedly connected at the bottom of the ground rod body, the bottom portion of the screw rod is a drilling head, and a rotating handle perpendicular to the ground rod body is arranged at the top of the ground rod body and provided with wiring terminals convenient in wire disassembling. When the ground rod encounters hard soil, the screwing type ground rod is easy to be inserted into the ground in a suitable depth, technical requirements can be met by a ground resistor, and personal safety of operators is guaranteed.

Description

A kind of screw-on earth rod
Technical field
The utility model relates to a kind of screw-on earth rod.
Background technology
When power line construction, maintenance, need to use earth rod to carry out ground connection, safety with the safeguard work personnel, during earth rod ground connection, earth resistance there is certain requirement, harder such as soil property, earth rod inserts underground comparatively difficulty, because buried depth is inadequate, earth resistance can not satisfy specification requirement, will injure operating personnel's personal safety.
The utility model content
The technical problems to be solved in the utility model provides a kind of screw-on earth rod, uses it can insert relatively easily underground appropriate depth, to satisfy the specification requirement of earth resistance.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: it comprises earth brace, is fixedly connected with screw rod in the bottom of earth brace, and the screw rod bottom is drill bit, and the earth brace top is provided with the rotary handle of perpendicular connection.
The utility model further improves and is: the end of rotary handle is provided with the ground wire binding post; Earth brace is fixedly connected with screw rod by pin.
The beneficial effect that adopts technique scheme to produce is: the bottom at earth brace in the technical program is fixedly connected with screw rod, the screw rod bottom is drill bit, the earth brace top is provided with the rotary handle of perpendicular connection, when earth rod ground connection runs into the harder situation of soil property, earth brace is pounded into the ground next part, then rotary handle, screw rod can insert underground easily, the while flight has increased the contact area with ground, reduced earth resistance, easily make earth rod insert the suitable degree of depth, make earth resistance satisfy specification requirement, ensured operating personnel's personal safety.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In the accompanying drawings: 1, earth brace; 2, screw rod; 3, rotary handle; 4, ground wire binding post; 5, pin.
Embodiment
By embodiment shown in Figure 1 as can be known: it comprises earth brace 1, is fixedly connected with screw rod 2 in the bottom of earth brace 1, and screw rod 2 bottoms are drill bit, and earth brace 1 top is provided with the rotary handle 3 of perpendicular connection; The end of rotary handle 3 is provided with ground wire binding post 4; Earth brace 1 is fixedly connected with screw rod 2 by pin 5.
Using method:
When earth rod ground connection runs into the harder situation of soil property, earth brace is pounded into the ground next part, then rotary handle, screw rod can insert underground easily, the while flight has increased the contact area with ground, has reduced earth resistance, easily makes earth rod insert the suitable degree of depth, make earth resistance satisfy specification requirement, ensured operating personnel's personal safety.
