Abstract

The utility model relates to a bird nest preventing device of a cross arm of a telegraph pole. The bird nest preventing device of the cross arm of the telegraph pole is characterized by comprising a rectangular blocking board (1), a semi-circular groove is formed in one side of the blocking board (1), two U-type clamping boards (3) are installed on the other opposite side, each U-type clamping board (3) is provided with a threaded hole, each threaded hole is internally provided with a bolt, and therefore the blocking board (1) can be fixed to the cross arm. On trial, it proves that by the adoption of the bird nest preventing device, gaps among the cross arm, M iron and the telegraph pole are completely sealed, the probability that birds nest on the cross arm of the telegraph pole is largely decreased, and power facilities on the telegraph pole are protected.

Description

The anti-bird's nest device of electric pole cross-arm
Technical field
The utility model relates to the anti-bird's nest device of a kind of electric pole cross-arm.
Background technology
Due to the particularity of wire pole structure; be very easy to attract birds; especially magpie is nested thereon; but nest, the safety of electric pole and upper electric power facility thereof is tended to have a negative impact; in serious situation, even can cause the accidents such as power-off; at present existing multiple safeguard or measure are used for stoping birds to nest, for example, bird-scaring unit miscellaneous just often can be installed on electric pole cross-arm.
But find through use after a while; junction in the middle of cross-arm and between electric pole is often provided with M iron; this M iron is the iron bar of M type; therefore between cross-arm, M iron, electric pole three, can leave the gap of similar branch shape; be easy to attract the birds such as magpie to nest at these gap locations; because these gaps are very close to electric pole, therefore be often not suitable for installing bird-scaring unit here, even if installation also can cannot be protected these gap locations due to the blind area of bird-scaring unit self reluctantly.
Utility model content
The purpose of this utility model is to provide the anti-bird's nest device of a kind of electric pole cross-arm, can prevent that the gap of birds between cross-arm, M iron, electric pole three from nesting after use.
The anti-bird's nest device of a kind of electric pole cross-arm, its special feature is: the plugging plate that comprises rectangle, a side at this plugging plate has semicircular groove, and at relative opposite side, two U-shaped clamping plate are installed, on each U-shaped clamping plate, all have screwed hole, bolt is installed in screwed hole, thereby plugging plate can be fixed on cross-arm.
Wherein be vertically installed with 3 in plugging plate one side upward and refuse bird plate, and every top of refusing bird plate is blade-like or spininess.
Wherein be coated with two-sided tape at the plugging plate semicircular recess edge of one side place.
Through probationary certificate, adopt after anti-bird's nest device of the present utility model, the gap between cross-arm, M iron, electric pole three can be sealed completely, therefore greatly reduce the probability that birds are nested herein, protect the electric power facility on electric pole.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model is the anti-bird's nest device of a kind of electric pole cross-arm, comprise the plugging plate 1 of rectangle, a side at this plugging plate 1 has semicircular groove, and at relative opposite side, two U-shaped clamping plate 3 are installed, on each U-shaped clamping plate 3, all have screwed hole, bolt is installed in screwed hole, thereby plugging plate 1 can be fixed on cross-arm.
Wherein be vertically installed with 3 in plugging plate 1 one side upward and refuse bird plate 2, two of its middle left and rights are refused bird plate 2 and are arc, and the middle bird plate 2 of refusing is S type, and every top of refusing bird plate 2 is blade-like or spine (pin) shape, is coated with two-sided tape in addition at the plugging plate semicircular recess edge of 1 one side place.
Using method of the present utility model is:
When use by plugging plate 1 first circular groove alignment electric pole surface, cross-arm is clipped in the middle of two U-shaped clamping plate 3 simultaneously, then tightening 2 bolts is fixed on plugging plate 1 on cross-arm, under the effect of double faced adhesive tape, make sealing completely between groove and electric pole, if which floor double faced adhesive tape space still can paste more greatly more between groove and electric pole, or on double faced adhesive tape, paste some waste and old cable insulation skins to fill up space.
