Abstract
The utility model relates to a kind of spiral high-voltage earthing rod, it is characterized in that, comprise: an insulating bar, fix a guide post above action bars, guide post the first half is straight reinforcing bar, and the latter half is carved with screw thread, described guide post the first half overlaps a spring, described lower spring end contact thread ring, the card line groove at guide post top described in upper-end contact, described thread ring is connected by ground connection with described gib head.This novel beneficial effect is: the speed (improving 154% than prior art) 1, improving mounting earth connection; 2, reduce the labour intensity more than 30% of mounting earth connection, save staff's muscle power; 3, shorten nearly 3 times of the interruption duration of scheduled outage or repairing, improve power supply reliability and job security.
Description
Technical field
The utility model relates to a kind of spiral high-voltage earthing rod.
Background technology
Earth connection is one of most important Work tool in line work, is one safety curtain of protection circuit staff, and be the lifeline of electrical employee, its importance is self-evident.In our daily various line works in a large number, mounting earth connection is maximum is also a most important procedure, and is that in line work elapsed time is relatively for a long time and the larger mutually requisite operation of labour intensity.Regardless of in scheduled outage or in repairing, the time shortening mounting earth connection all can greatly reduce the time of line outage, improves power supply reliability.The spiral compression formula earth rod of our use is now when mounting, a lot of circle bolt need be twisted earth rod bayonet socket is tightened up, more time-consuming, and quite consume hand-power when operating with more stiff 10kV insulating gloves, often twisted will having a rest of a phase, this just consumes the time greatly, and treat the time more longly more consumes one's strength on bar, follow-up work medium velocity may be caused slack-off, the problems such as distraction, even safety problem.
High-voltage earthing rod can be divided into according to bayonet arrangement difference: hook (duckbilled) formula earth rod and spiral compression formula earth rod.Coupling type (duck-beak type) earth rod bayonet socket is made up of two panels springs steel, structure likeness in form duckbilled, and it is easy and simple to handle, and only need an extension, on wire to draw, but mount insecure, touching is easily dropped, and there is potential safety hazard.Spiral compression formula earth rod bayonet socket is made up of a string long distance bolt, and during use, bayonet socket is packed into circuit, bolt tightens by rotation process bar, have be connected firmly, advantage that fail safe is high.But a lot of circle bolt need be twisted when mounting earth rod bayonet socket is tightened up, comparing and wasting time and energy.
Utility model content
The purpose of this utility model is to provide a kind of spiral high-voltage earthing rod, greatly can improve speed and the fail safe of ground wire hitching, and then increase work efficiency and power supply reliability.
A spiral high-voltage earthing rod, comprising:
Guide post, its first half is smooth surface, and Lower Half has external screw thread;
Conductive hook component, its top has gib head, and the gib head that the end of described gib head has oblique below connects mouth 4, its underpart has thread ring, described thread ring is set in the periphery of described guide post, and can freely move up and down relative to the first half of described guide post and mate with the external screw thread of Lower Half, its middle part connected between the gib head 1 of described conductive hook component and thread ring 8 has ground connection;
Snap features, it is arranged on the upper end of described guide post, and has card line groove, and described card line groove is relative with the middle part of described gib head, and both form card line fastening hole, and the end of described gib head stretches out in described snap features;
Wherein, be provided with spring between described snap features and described thread ring, described spring housing is located at the periphery of described guide post, and the length of described spring is for support described thread ring near described externally threaded upper end in its natural state.
Optimally, described ground connection 7 is two through holes at the middle part of conductive hook component, and ground wire is tied up on conductive hook component by described two through holes.
Optimally, described conductive hook component is that metal is made.
Optimally, guide post overall length 11cm, first minister 8cm of wherein said guide post, the Lower Half length 3cm of described guide post, the long 3cm of thread ring.
Optimally, gib head connects mouth and is extended for 2cm, and the angle of itself and action bars is 45 °.
Optimally, described spiral high-voltage earthing rod is hooked in overhead wire conductive pane.
The beneficial effects of the utility model are: the speed 1, improving mounting earth connection, improve 154% than prior art; 2, reduce the labour intensity more than 30% of mounting earth connection, save staff's muscle power; 3, shorten nearly 3 times of the interruption duration of scheduled outage or repairing, improve power supply reliability and job security.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to specification word to make those skilled in the art.
The utility model comprises an insulating bar 10, a guide post is fixed above insulating bar 10, described guide post the first half 6 is straight reinforcing bar, the latter half 9 is carved with screw thread, described guide post the first half overlaps a spring 5, spring 5 times end in contact thread rings 8, the card line groove 3 at guide post top described in upper-end contact, thread ring 8 is connected by ground connection 7 with gib head 1.Described guide post overall length 11cm, the long 8cm of wherein said guide post the first half 6, described guide post the latter half 9 length 3cm.Thread ring 8, ground connection 7 and gib head 1 as a whole.Have sliding rail 2 inside gib head 1, it is 2cm that the gib head of gib head 1 front end connects mouth 4 length, and the angle of itself and action bars 10 is 45 °.Thus can, according to the needs at scene, the retractility of spring be first utilized by earth connection earth rod snap features to be inserted in circuit, 2 seconds consuming time; Again earth rod is tightened, generally need twist 3 times, 2 seconds consuming time; Be first earth rod is unscrewed when needs take off earth rod, generally need twist 3 times, 2 seconds consuming time; Earth rod snap features is taken off from circuit, 2 seconds consuming time.The utility model, to the improvement of earth rod bayonet socket, uses spring compression to reduce the methods such as bolt length, compared with prior art greatly shortens hookup time, saves staff's muscle power, increases work efficiency thus improve power supply reliability.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in specification and execution mode utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
