Abstract

A no-screw non-welded mesh ground lead is characterized in that a plurality of tubular members parallel to the axis of a ring are evenly and fixedly connected to the outside of the ring, having rectangular section and used to sleeve a power line pole; the tubular members are flush with upper and lower end faces of the ring; a metal rod is inserted into each tubular member from top to bottom; the ring and the tubular members are integrally cast. The no-screw non-welded mesh ground lead is fitted with no need for screws or welding, and great convenience is brought to field construction. The no-screw non-welded mesh ground lead is convenient to mount and can be mounted just by directly sleeving the root of the pole with the ring and burying the pole; pole burying and lead laying are completed at once.

Description

The netted earth connection that screwing does not weld
Technical field
The present invention relates to lightning-arrest with the lightning-arrest earth connection of using of earth connection, particularly power transmission line electric pole.
Background technology
The situation large in order to change grounding resistance, thunder and lightning release function is poor, the inventor once made and adopted netted earth connection (as shown in Figure 1 a, 1 b).Many initial earth connections are that to be welded on circular boop lip-deep, like this, although met connection request.But because of will be first as steel plate get the raw materials ready, cut out, punching press and be curled into circular etc., so procedure is many, difficulty is relatively large, in addition these work often need to complete in the place that has stamping machine and welding equipment, conditional request is high, and be welded into after entirety at many branch lines, bring difficulty to assembling, transport.
Summary of the invention
The object of this invention is to provide the netted earth connection that a kind of plug-in type assembles, on-the-spot not screwing easy for installation does not weld.
The object of the present invention is achieved like this: the netted earth connection that a kind of not screwing does not weld, as being sleeved on, lateral surface that the cross section on power transmission line electric pole is rectangular annulus is uniform to be fixedly connected with and multiple cylinders of this annulus axis parallel, this cylinder flushes with the upper and lower end face of this annulus, and in each cylinder, is plugged with from bottom to top a bonding jumper; Above-mentioned annulus and all cylinders are monoblock cast part.
Above-mentioned annulus height is 100mm.
Above-mentioned cylinder is 12.
Compared with prior art, the invention has the beneficial effects as follows:
1, grounding wire mounting timing only need be inserted bonding jumper in semicircular cylinder successively from bottom to top, when assembling without screw, without electric welding, for site operation brings great convenience.
2, easy for installation.
The cylinder of earth connection is directly enclosed within to electric pole root, and then buries electric pole underground, electric pole is buried underground with earth connection and is laid simultaneously and complete.
Brief description of the drawings
Fig. 1 a, Fig. 1 b are respectively the schematic diagrames (not fixing metal bar state) of existing circular ring type earth connection and circular boop formula earth connection.
Fig. 2 is the schematic diagram of the cylinder cast member of this earth connection.
Fig. 3 is the schematic diagram of this netted earth connection shown in Fig. 2.
Embodiment
Fig. 2 illustrates, the netted earth connection that a kind of not screwing does not weld, be fixedly connected with and multiple cylinder 1a of this annulus 1 axis parallel as to be sleeved on cross section on power transmission line electric pole be that the lateral surface of rectangular annulus 1 is uniform, this cylinder 1a flushes with the upper and lower end face of this annulus 1, and is plugged with from bottom to top a bonding jumper 2 in each cylinder 1a; Above-mentioned annulus and all cylinder 1a are monoblock cast part.Annulus 1 is highly 100mm.Cylinder 1a is 12.
Fig. 3 illustrates, the bonding jumper of insertion is Ф 10mm, so vertically internal diameter design in hole is also 10mm, therefore become and combine closely to each other, the height that adds annulus 1 is that 100mm(internal diameter and electric pole are suitable), be enough to metal strips for grounding line to insert firmly fastening.
This earth connection not screwing does not weld, and adopts direct insertion connected mode, and this cylinder cast member need to carry out designing and producing of cast dies, although early investment is larger, can reduces workload and form batch production, so very worth.
Punching block is mainly made up of electromagnetic high-temperature stove, steel body patrix, steel body counterdie, and wherein high temperature furnace is mainly fusing molten iron, makes it to flow into from solution channel, to solidify aftershaping.Steel body patrix plays interior gear solution and extracts storing, i.e. demoulding effect, steel body counterdie plays the firm effect of outer gear solution and location, the diameter of inside and outside die body is poor up and down, the thickness of annulus just, the height of blending is also the height of annulus, and external mold is with the real core body of multiple 10mm, after the demoulding, be periphery bar hole.
In punching block, by after making with the annulus of vertical cylindrical void, can on the vertical cylindrical void of annulus periphery, insert 1000mm length, and be bent into the bonding jumper of unified model through crimping, as shown in Figure 3, a set of complete net like lightning protection line is successful.
