Abstract
The utility model discloses a portable retractable cord device for ground resistance testing. The portable retractable cord device comprises a spool, a spool seat and three wire reels, wherein the spool is rotatably arranged on the spool seat; a connection key I, a connection key II and a connection III are fixedly arranged on the spool; each two of the three connection keys are spaced at an interval greater than or equal to the width of the wire reels; and the wire reels are slidingly arranged on the spool. The three wire reels are used for retracting test wires respectively so that intertwining between test wires may be effectively prevented, and besides, the wire reels may slide on the spool enabling the keyways on the wire reels to cooperate with and be separated from respective connection keys so that synchronization rotation or individual rotation of the wire reels may be realized. Therefore, the provided portable retractable cord device has the advantages of a simple structure, high portability, convenient use, improved working efficiency, and solved problems of a current retractable cord device in the prior art.
Description
Technical field
The utility model relates to a kind of electric power aid, particularly a kind of portable grounding resistance test retractable cable device.
Background technology
Electric line must carry out periodic pole tower ground resistance and measure by the operating standard regulation, and the operations staff generally adopts earth resistance tester to measure.Measuring process need be with the measuring junction of earth resistance tester and tested earthing device and 20 meters voltage probe, 40 meters the respectively corresponding wiring connection of current probe.The annealed copper wire that wiring connects usually with adopt directly circle around, carry out the retractable line with the mode of line plate winding and operate.There is following shortcoming: 1, need carry three line plates (or coiling) of separation, more scattered, to carry the instrument amount bigger, easily causes careless omission; 2, take in irregular, easy tangled up and knotted, increase wiring time, and accelerate annealed copper wire and wear out; 3, take-up process need be carried out respectively, has reduced work efficiency.Because above shortcoming exists, and makes and all will arrange every year great amount of manpower, thing amount and time to finish this work, has not only increased cost, has also increased labour intensity.
Therefore, be necessary to work out a kind of portable grounding resistance test retractable cable device, simple in structure, easy to use, have advantages such as intensity height, long service life simultaneously.
The utility model content
In view of this, the purpose of this utility model provides a kind of portable grounding resistance test retractable cable device, has overcome the defective of prior art, has improved work efficiency.
The purpose of this utility model is achieved through the following technical solutions:
A kind of portable grounding resistance test retractable cable device, comprise roll, coiling axle bed and three wire spools, described roll is rotating to be arranged on the coiling axle bed, be set with connecting key I, connecting key II and connecting key III on the described roll, in twos spacing is more than or equal to the width of wire spool between described three connecting keys, and described wire spool slidably is arranged on the roll;
Further, also be provided with the wire spool plectrum between the described wire spool, described wire spool plectrum is rotating to be arranged on the coiling axle bed;
Further, portable grounding resistance test retractable cable device also comprises rotary handle, and described rotary handle is fixedlyed connected with roll one end;
Further, two sides that described coiling axle bed is parallel with roll, one of them side is provided with handle, and another side is provided with wire hole.
The beneficial effects of the utility model are: the utility model utilizes three wire spools folding and unfolding p-wire respectively, can effectively avoid p-wire to twine each other, wire spool can slide at roll the keyway on the wire spool is cooperated with corresponding connecting key and the synchronous rotation or the rotation separately that separate to realize wire spool in addition, the utility model is simple in structure, portably use conveniently, therefore, improve work efficiency, overcome the defective of prior art.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being apparent to those skilled in the art to investigating hereinafter, perhaps can from practice of the present utility model, obtain instruction.Target of the present utility model and other advantages can realize and obtain by following instructions.
