Description

Bird-proof cover

Technical field

The utility model belongs to electric and electronic technical field, relates to a kind of bird-proof cover.

Background technology

The birds droppings flashover fault occurring on insulator is a major reason that affects the normal operation of electrical network, birds droppings flashover is a kind of unexpected incidents, before flashover, can not there is not any sign yet, it when flashover, is seldom also people's finding, therefore in regular maintenance process, attendant is difficult to drive and prevent the stop activity of birds on insulator, especially electrical network the vast region of process, be difficult to stop the stop activity of birds on insulator, make the operation of electrical network be subject to all the time the harmful effect of birds droppings.

Utility model content

The purpose of this utility model is to provide a kind of bird-proof cover, has solved attendant in prior art and has been difficult to drive and prevent the stop activity of birds on insulator, the problem that birds droppings flashover fault can not significantly be eliminated.

The technical scheme that the utility model adopts is, a kind of bird-proof cover, comprise a canopy, canopy radially has a upper and lower penetrating straight trough, be provided with the mounting edge of reinforcement at the top of canopy, mounting edge upper surface is installed with bow, and bow is fixedly connected with mounting edge, and bow is fixedly connected with clamping plate.

Bird-proof cover of the present utility model, its feature is also:

The main body of bow is split ring, the opening of split ring is radially consistent with straight trough center line, split ring vertically has many group bolt hole B, the bolt hole B of split ring adopts bolt A to be fixedly connected with mounting edge, the diametric(al) that split ring internal circular surfaces is faced opening is installed with boom plate, boom plate stage casing is boom plate semicircular ring, the boom plate semicircular ring in boom plate stage casing is concentric relative with the clamping plate semicircular ring in clamping plate stage casing, on boom plate, be provided with two groups of bolt hole A corresponding with two groups of bolt hole C that arrange on clamping plate, and be fixedly connected with by bolt B.

On straight trough, be coated with a compressing tablet, the both sides of compressing tablet are provided with lug.

The beneficial effects of the utility model are, are adapted to the suspension insulator of various models, can prevent from accumulating by birds droppings the pollution flashover causing, effectively reduce birds droppings flashover fault, applicable to regional temperature at-40 DEG C to+60 DEG C.And can increase creep distance, ageing-resistant, resistance to galvanic corrosion, resistance to electric arc, improve pollution flashover voltage, there is good mechanical anti-tensile, resistance to compression, shock resistance.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.

With reference to Fig. 1, Fig. 5, the structure of the utility model device is, comprise a canopy 1, canopy 1 radially has a upper and lower penetrating straight trough 14, be provided with the mounting edge 2 of reinforcement at the top of canopy 1, mounting edge 2 upper surfaces are installed with bow 3, and bow 3 is fixedly connected with mounting edge 2 by multiple bolt A12, bow 3 is also fixedly connected with clamping plate 4 by two groups of bolt B 13, and bow 3 and clamping plate 4 are clamped in axle journal 16 positions of insulator 15 upper ends jointly;

With reference to Fig. 2, Fig. 3, Fig. 4, the main body of bow 3 is split ring 5, the opening of split ring 5 is radially consistent with straight trough 14 center lines, split ring 5 vertically has many group bolt hole B9 (in figure, embodiment is four groups), the bolt hole B9 of split ring 5 adopts bolt A12 to be fixedly connected with mounting edge 2, the diametric(al) that split ring 5 internal circular surfaces are faced opening is installed with boom plate 6, boom plate 6 stage casings are boom plate semicircular ring 7, the boom plate semicircular ring 7 in boom plate 6 stage casings is concentric relative with the clamping plate semicircular ring 11 in clamping plate 4 stage casings, on boom plate 6, be provided with two groups of bolt hole A8 corresponding with two groups of bolt hole C10 that arrange on clamping plate 4, and be fixedly connected with by bolt B 13,

With reference to Fig. 6, on straight trough 14, be coated with a compressing tablet 17, the both sides of compressing tablet 17 are provided with lug 18, for adopting screw that compressing tablet 17 is fixedly connected with straight trough 14 both sides.

Canopy 1 and compressing tablet 17 all adopt SMC material to make.

Installation process of the present utility model is,

First, adopt bolt A12 to be fixedly connected with mounting edge 2 the bolt hole B9 of split ring 5, make bow 3 and canopy 1 fixing reliable;

Then, the axle journal 16 of insulator 15 upper ends is packed into along the straight trough 14 of canopy 1 in the boom plate semicircular ring 7 in boom plate 6 stage casings, again the clamping plate semicircular ring of clamping plate 4 11 and the boom plate semicircular ring 7 of boom plate 6 are clamped to axle journal 16, by the fixing boom plate 6 of bolt B 13 and clamping plate 4, insulator 15, bow 3 and clamping plate 4 are fixed as one;

Finally, adopt screw that compressing tablet 17 is fixedly connected with straight trough 14 both sides, canopy 1 just becomes a complete umbrella cover.

Device of the present utility model, the canopy 1 of installing in insulator 15 upper ends, canopy 1 upper surface that can guide birds to stop falling, because the Zhou Jing of canopy 1 is enough to avoid the birds droppings caused birds droppings flashover fault that falls, thereby ensure the safety of circuit operation, significantly reduced the probability of happening of birds droppings flashover fault.
