Abstract

The utility model provides a bird nesting prevention device for a wire pole, which is used for preventing birds from nesting on a conducting wire connector of the wire pole. The device mainly comprises a front baffle plate and a rear baffle plate and is characterized in that the upper ends of the front and rear baffle plates are connected through an upper convex plate; a folded edge is arranged at the lower end of the rear baffle plate; corresponding mounting holes are formed in the front and rear baffle plates; and plugs are mounted on two sides of the upper convex plate. The device can effectively prevent the birds from staying and nesting on the conducting wire connector of the wire pole, can also prevent line fault caused by corrosion of iron pieces of the wire pole, has a remarkable bird prevention effect and is reliable in protection.

Description

The line bar is prevented the bird from building nest device

Technical field

The utility model belongs to anti-bird from building nest device, particularly a kind of device of nesting on the wire connector of the online bar of birds of preventing.

Background technology

Along with the improvement of ecotope, various birds are increased gradually.Because the line joint element for bar of departments such as electric power is firm, smooth, birds are often taken place in this phenomenon of nesting, especially magpie likes best at shaft tower and nests, the nest materials include conductors such as iron wire, and materials are long, in case run into blast and rainy weather line-to-ground or short trouble taking place easily, cause large-area power-cuts, brings significant damage for local economic development, people's life and social stability.Particularly in recent years, almost have every year because Bird's Nest causes the line tripping accident and take place.For preventing Bird's Nest to the influence of circuit, the normal charged method of removing by force of brake pull-rod that adopts is subject to factor affecting such as weather, geography but remove now, makes operating personnel's inherently safe be difficult to guarantee.Owing to birds extremely strong adaptive capacity and love nest habit, bird is nested again in less than several days simultaneously.Present windmill-type bird-scaring unit commonly used, pretective acreage is little, and the life-span is short, easily breaks down, and has been not suitable for using at high-tension distributing line.Another kind of bird-proof device is bird-resistant, because the parachute-opening scope is big, pricker is long, live wire and thorn umbrella hypotelorism easily cause line-to-ground and short circuit accident under the inclement weather conditions.

Summary of the invention

The purpose of this utility model is to provide a kind of anti-bird from building nest device of the line bar of nesting on the online joint element for bar of birds that prevents, protection is reliable, security of operation.

The utility model is achieved in that

The line bar is prevented the bird from building nest device, mainly comprises front apron and backboard, it is characterized in that: the limit, upper end of front apron and backboard is connected by last flange; The limit, lower end of backboard is provided with the flanging of invagination; Last flange both sides are equipped with shutoff; Have corresponding installing hole on front apron and the backboard.

Be provided with set bolt in the installing hole, described front apron leaves groove in the middle of the bottom.

The utility model is directly installed on the cross-arm of line bar after adopting said structure, can prevent from effectively that the online joint element for bar of birds top from stopping to nest, and also can prevent because the line fault that the corrosion of line bar ironware causes.Anti-bird effect is obvious, protection is reliable, has effect simple in structure, easy for installation, security of operation.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model, and Fig. 2 is the end view of Fig. 1.

In the accompanying drawing, 1 is that front apron, 2 is that backboard, 3 is that last flange, 4 is that flanging, 5 is that shutoff, 6 is that groove, 7 is bolt.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

As shown in Figure 1, the utility model is a kind of device of nesting on the online joint element for bar of birds of preventing, mainly comprises rectangular front apron 1 and backboard 2, and front apron 1 can be arranged in parallel with backboard 2, also can have certain inclination angle.The place, limit, upper end of front apron 1 and backboard 2 is provided with flange 3, and flange 3 connects front apron 1 and backboard 2 on this, makes it to become one, and is used for clamping the cross-arm of online bar.Cross-arm is used for connecting electric insulator.The described cross section of going up flange 3 is designed to inverted V-shaped, drift angle≤70 ⁰, the cross section of last flange 3 also can be designed to circular arc, is unfavorable for that birds are stopping.Shutoff 5 is installed in both sides at last flange 3, prevents that birds from entering.Shutoff 5 can adopt screw and last flange 3 to rivet together, and also can adopt the mode of colligation silk binding, makes it to become one.For ease of installing, what guarantee to install is firmly safe and reliable, as shown in Figure 2, is provided with the flanging 4 of invagination on the limit, lower end of backboard 2,2 one-tenth 90 of this flanging 4 and backboards ⁰Angle; Flanging 4 can be installed on the edge of cross-arm.As shown in Figure 1, in the middle of the bottom of front apron 1, leave square groove 6, cooperate with cross-arm arc parallels.Have corresponding installing hole on front apron 1 and the backboard 2, be provided with set bolt 7 in the installing hole, also can directly adopt the colligation silk, front apron 1, backboard 2 colligations are fixed on the cross-arm.

During installation, front apron 1, backboard 2 are installed on the cross-arm; The groove 6 of front apron 1 snaps in cross-arm arc parallels, and the flanging 4 of backboard 2 is stuck in the edge of cross-arm, and both sides install shutoff 5 additional, and is fixing by bolt 7 at last.
