Disclosure of Invention

The invention aims to provide a porcelain insulator with an electricity testing grounding ring and a bird damage prevention structure safety cover, which aims to solve the problems that the top end of the safety cover in the prior art is provided with a butt joint seam, and rain and snow are not smoothly discharged; easily causing bird damage.

The technical scheme of the invention is as follows: a porcelain insulator with an electricity testing grounding ring and a bird damage prevention structure safety cover comprises a porcelain insulator with a rain-proof disc, wherein a metal end is arranged at the upper end of the porcelain insulator, a metal screw and a fixing nut are arranged on the axis of the lower end of the porcelain insulator, a wiring clamp is arranged at the top end of the metal end, and one end of the wiring clamp is connected with the electricity testing grounding ring through a connecting arm; the metal end, the jointing clamp and the connecting arm of the electricity testing grounding ring are all installed in a safety cover.

The invention has the advantages that: the sharp top at the top end of the safety cover is used as a bendable connector and penetrates through the center line of the whole top, so that butt joint seams at the top end are eliminated, and the sealing performance is improved; the pointed top at the top end prevents birds from falling and building bird nests, and bird damage is effectively prevented. The grounding ring extends to one side, so that the grounding operation is facilitated; the strength of the connecting arm is improved.

Detailed Description

Referring to fig. 1 to 7, the first embodiment of the porcelain insulator with the electricity testing grounding ring and the bird damage prevention structure safety cover of the invention comprises a porcelain insulator with four disc-shaped rain-proof discs 1, wherein the upper end and the lower end of the porcelain insulator are respectively provided with a metal end 5, the axis of the lower end is provided with a metal screw 6 and a fixing nut, the top end of the metal end 5 at the upper end is provided with a wiring clamp 2, and the wiring clamp 2 is connected with an electricity testing grounding ring 8 at one end of the wiring clamp 2 through a connecting arm 9 by a top plate; the metal end 5 at the upper end, the jointing clamp 2 and the connecting arm 9 are all installed in an insulating safety cover 3 (the left side and the right side of the insulating safety cover are provided with power line protective pipes 31 for passing through power lines).

The main structure of the safety cover 3 is (see fig. 6 and 7), which is composed of a half box body, an upper box body 37 and a lower box body, wherein the half box body covers the metal end 5 and the half part of the binding clip 2, which is opposite to the electricity testing grounding ring 8; the upper box body 37 covers the other half of the wiring clamp 2 and is oppositely buckled with the upper part of the half box body, the top ends of the upper box body and the half box body are mutually connected through a bendable connector, and the lower side of the upper box body is provided with an upper groove 32 used for penetrating through the connecting arm 9 of the electricity testing grounding ring 8; the lower box body is oppositely buckled with the lower part of the half box body, the upper edge of the lower box body is inserted into the inner side of the lower edge of the upper box body, and a lower groove 33 corresponding to the connecting arm 9 of the electricity testing grounding ring 8 is arranged; the butt joint edges of the half box body and the lower box body are provided with power line protective pipes 31 which correspond to the two sides of the jointing clamp, protrude outwards and gradually reduce the diameter; the bottom ends of the half box body and the lower box body are provided with semicircular holes for penetrating through the necks of the porcelain insulator; a pair of lugs 34 corresponding to each other are respectively arranged on the butt joint edges at two sides of the upper box body and the half box body, at least a pair of lugs 34 corresponding to each other are respectively arranged on the butt joint edges at two sides of the half box body and the lower box body, a through hole is arranged on the lug 34, and the lock catch 12 is arranged in the through hole.

An n-shaped water retaining edge is arranged along the outer side edge of the upper groove 32; the outer sides of two opposite sides of the lower groove 33 are respectively provided with a water retaining edge, and the water retaining edge covers the top ends of the two water retaining edges along the two sides of the lower end.

The contact surfaces of the two sides of the lower end of the water retaining edge and the top ends of the two water retaining edges are mutually matched inclined surfaces so as to improve the sealing property. The above-described structure of the safety shield 3 is prior art.

The improved parts of the safety cover 3 of the invention are as follows: a peak 35 is provided at the center line of the top end of the safety cover 3 as a bendable connecting body, both ends of which extend to the left and right ends (in fig. 2) of the top end, and the peak 35 facilitates drainage and also prevents birds and litter from falling.

In addition, the electricity testing grounding ring 8 is also improved, and the metal exposed edge (the grounding edge without the insulating layer) of the electricity testing grounding ring 8 extends towards one side, so that the grounding hook can be easily hung on the grounding edge of the electricity testing grounding ring 8 during grounding operation. One end of the connecting arm 9 connected with the electricity testing grounding ring 8 is also expanded to form a triangle, so that the connecting strength of the electricity testing grounding ring 8 is increased.
