Example Embodiment

[0027] Example 1:

[0028] like Figure 1 to Figure 5 As shown, a double cross-arm power distribution line anti-bird damage device includes two protective units symmetrically arranged, each protective unit includes a protective plate 1 and sliding pieces 2 arranged on both sides of the protective plate 1, in the protective One end of the plate 1 is provided with a semicircular groove, and two through holes 6 are arranged on the opposite end, and the sliding sheet 2 is provided with a long strip hole 3, and the bolt 4 penetrates the through hole 6 and the long strip hole 3 The sliding piece 2 is connected with the protective plate 1; the two protective units are fixedly connected through both sides of the semicircular groove.

[0029] Elongated openings 5 ​​are provided on the protective plates on both sides of the semicircular groove, and the two protective units are connected together by bolts 4 passing through the elongated openings 5 ​​. In the actual installation and use...

Example Embodiment

[0031] Example 2:

[0032] This embodiment provides a bird protection device for a double cross-arm power distribution line, the structure of which is as described in Embodiment 1, the difference is that a layer of anti-corrosion layer is provided on the outer surface of the protection unit. Since the anti-bird device is made of low-cost iron plates, and because the anti-bird device needs to be used in the open air, rusting will inevitably occur after a long period of exposure to the sun and rain, and the additional anti-corrosion layer can prolong Its service life is long and maintenance costs are reduced.

Example Embodiment

[0033] Example 3:

[0034] like Image 6 As shown, a double cross-arm distribution line anti-bird device, the structure is as described in embodiment 1, the difference is: the novel anti-bird device also includes a rubber cylindrical anti-bird plug 7. The advantage of this design is that for the redundant holes on the cross arm, the holes are blocked with anti-bird plugs, which can effectively completely prevent birds from nesting.

Abstract

The invention relates to a double cross arm distribution line novel bird hazard prevention device and an application thereof. The double cross arm distribution line novel bird hazard prevention device comprises a protection plate and a fixing slice, wherein a semicircular groove is formed in one side of the protection plate, two through holes are formed in the other side of the protection plate, opposite to the semicircular groove, bolts are arranged in the two through holes, two threaded holes are formed in the fixing slice, and the bolts run through the threaded holes, and thereby connect the protection plate and the fixing slice together. The double cross arm distribution line novel bird hazard prevention device can effectively prevent birds from nesting by using the protection plate and a bird prevention stopper in combination, and then can shorten bird hazard patrol time, reduces cost expense, can effectively eliminate influences of bird hazards on safe running of a distribution line, decreases the number of tripping times of the distribution circuit, and obtains good economical benefit.

Description

technical field [0001] The invention relates to a bird-prevention device for a double cross-arm power distribution line and its application. Background technique [0002] In distribution lines, due to the particularity of the pole structure, it is very easy to attract birds, especially magpies to build nests on it. Bird nests are mostly at the cross-arms of electric poles and towers. The materials used to build bird nests include branches, thatch, tinfoil, cloth strips, and iron wires. These materials are likely to cause discharge tripping and short-circuit grounding faults when they encounter rain or fog. In addition, bird droppings falling on the porcelain bottle of the line will cause flashover of the porcelain bottle, causing a power outage and affecting the safe operation of the power grid. Nesting often has an adverse effect on the safety of utility poles and the power facilities on them, and in severe cases, it may even lead to accidents such as power outages. At pre...
