Description

Technical Field

[0001] The utility model relates to the technical field of grounding devices, in particular to a grounding device for a power transmission tower. Background Art

[0002] The transmission tower grounding device is an important part of the transmission line. It is the general term for the grounding body and the grounding down conductor. Its function is to ensure that the lightning current is reliably discharged into the earth to protect the insulation of the line equipment, reduce the line lightning tripping rate, improve the operation reliability of the line and avoid personal injury caused by step voltage.

[0003] There is a high-voltage transmission tower grounding device (whose authorization announcement number is: CN220456678U), which drives the shaft rod and the wire wheel to rotate by turning the handle, so that the wire wrapped on the wire wheel can be tightened, and then the bolt is turned to insert the bolt into the slot, so that the handle can be positioned to ensure that the wire is in a taut state. The wire in the taut state swings very little when blown by the wind, so that the wire will not contact other lines, which brings convenience and safety to the maintenance work; it has some shortcomings in practical application: the wire in a taut state for a long time will become fragile due to mechanical fatigue, thereby affecting the service life of the wire. Therefore, we propose this utility model to solve the above problems. Utility Model Content

[0021] Furthermore, the multiple partition plates 7 on the wire wheel 6 are arranged at equal intervals, and the wire wheel 6 is provided with multiple wheel grooves, and the multiple conductors 12 are separated by the multiple partition plates 7 on the wire wheel 6.

[0022] Furthermore, a wire barrel 13 is provided on the bottom cover 8 , and the wire 12 movably passes through the wire barrel 13 , so that the wire 12 can extend into the inner chamber 9 through the wire barrel 13 .

[0023] Furthermore, a plurality of through holes 14 are respectively opened on the top side of the grounding mounting plate 1 , and the plurality of through holes 14 are respectively located at the four corners of the grounding mounting plate 1 , so that the plurality of fixing spikes 15 can movably penetrate the corresponding through holes 14 .

[0024] Furthermore, fixing spikes 15 are inserted and installed in the plurality of through holes 14 , and the plurality of fixing spikes 15 are all penetrated to the outside of the grounding mounting plate 1 , so that the plurality of fixing spikes 15 penetrate the corresponding through holes 14 until they are inserted into the soil.

[0025] When in use: by adjusting the two mounting blocks 4 upwards to slide upwards in the corresponding mounting grooves 3, the two springs 5 ​​are subjected to force to deform and compress.

Then, by loosening the two mounting blocks 4, under the elastic force of the two springs 5, the grounding mounting plate 1 is placed on the ground. Under the action of the elastic stretching, the two mounting blocks 4 slide downward in the corresponding mounting grooves 3, driving the wire wheel 6 to move downward, so as to stretch the wire 12 to a certain extent, until the wire 12 wound on the wire wheel 6 is in a balanced state.
