Falling into due to sundries or coal after former earthing pole is squeezed into, is unable to judge accurately whether driving depth meets regulation, such as
The requirement against regulation of fruit driving depth will affect the safe operation of power supply system.
The utility model patent that number of patent application is 201621123628.1 discloses a kind of earthing pole extracting apparatus, passes through
Hook couples with earthing pole, is rotated by screw rod and extracts earthing pole.However existing ground connection extremely rod-like structure, it can not be with the extension
Hook cooperation, causes the device not to be available, or using limited.
Utility model content
In view of the above technical problems, the utility model provides a kind of detectable depth local earthed electrode, which can
To be convenient for measuring driving depth.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model are as follows:
A kind of detectable depth local earthed electrode, including earthing pole main body, the earthing pole body top are equipped with lid, institute
Lid is stated equipped with through-hole, lid is coupled by bolt with earthing pole main body, and the earthing pole main body is to have bottom structure, bottom
For syringe needle shape.
It further include Handleset, the Handleset includes connection ring and handle, and the handle passes through connection ring and ground connection
The connection of pole main body.
The connection ring includes the first snap ring and the second snap ring, and one end of first snap ring and one end of the second snap ring are cut with scissors
It connects, the other end of the first snap ring detachably couples with the other end of the second snap ring.
The other end of first snap ring is coupled by bolt assembly with the other end of the second snap ring.
The earthing pole body top is equipped with groove, is equipped on first snap ring and the second snap ring and groove cooperation
Protrusion.
There are two the handle is set, the first snap ring and the second snap ring, which respectively couple, a handle.
The utility model compared with prior art, has the beneficial effect that
The through-hole being equipped with by lid can protrude into a steel strand wires longer than earthing pole, be protruded into according to steel strand wires
Length, to judge the length of earthing pole.By Handleset, on the one hand when installing earthing pole, people's righting can be convenient；Together
When, when extracting earthing pole, can coupling by Handleset and extracting apparatus, facilitate and carry out extraction operation.
Detailed description of the invention
Fig. 1 is the principles of the present invention figure；
Fig. 2 is the axonometric drawing of the utility model；
Fig. 3 is the structural schematic diagram of the utility model Handleset；
Wherein: 1 is connecting terminal, and 2 be earthing pole main body, and 3 be open-work, and 4 be baffle, and 5 be steel strand wires, and 6 be bolt, and 7 are
Lid, 8 be groove, and 9 be handle, and 10 be the first snap ring, and 11 be the second snap ring, and 12 be protrusion.
Specific embodiment
The technical scheme in the utility model embodiment is clearly and completely described below, it is clear that described reality
Applying example is only the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention,
Every other embodiment obtained by those of ordinary skill in the art without making creative efforts, belongs to this reality
With novel protected range.
As shown in Figure 1, a kind of detectable depth local earthed electrode, including earthing pole main body 2, set at the top of earthing pole main body 2
There is lid 7, lid 7 is equipped with through-hole, and lid 7 is coupled by bolt 6 with earthing pole main body 2, and earthing pole and 7 side of lid are equipped with
Corresponding hole, the bolt 6 pass through earthing pole and lid 7 by the hole, and by realizing lid across end tightening nut
7 couple with earthing pole.The reliability of connection can more be guaranteed compared to common thread connection using such connecting mode.
Earthing pole main body 2 is to have bottom structure, specifically can be at the hollow 2 bottom bottom welding baffle 4(of earthing pole main body) it realizes.Meanwhile
Bottom is syringe needle shape, and earthing pole main body 2 is equipped with open-work 3 and connecting terminal 1.
After earthing pole installation, steel strand wires 5 can be protruded into earthing pole main body 2 by through hole, can according to built-in length
To judge the length of earthing pole.
Through-hole on lid 7 is eccentric orfice, prevents bolt 6 from blocking steel strand wires 5, limits it and protrude into inside earthing pole main body 2.
