Description

Technical Field

[0001] The utility model relates to the technical field of power equipment, in particular to an insulating cover for preventing bird damage on overhead lines. Background Technique

[0002] At present, the insulation rate of overhead distribution network lines in rural areas is still relatively low. Birds often build bird nests on the straight poles of overhead lines. The materials include wet branches, iron wires, etc. After the bird nests are formed, it is very easy to cause the bare conductor of the energized body to discharge with the metal parts of the insulators, cross arms, poles and other grounding bodies, resulting in line tripping, which has a serious impact on the stable operation of the distribution network lines.

[0003] There are various methods for preventing bird damage in the prior art, such as wind-driven bird repellers, bird repellents, needle insulator covers, etc. The current methods for preventing bird damage have the following defects: the wind-driven bird repellers rely on the wind to drive and stop rotating, but instead become good places for birds to perch; the efficacy of the bird repellents is short and not persistent; the needle insulator covers wrap the conductors on both sides of the insulator for a short distance and wrap fewer insulators, making them unstable. Content of the Utility Model

[0004] The purpose of the utility model is to provide an insulating cover for preventing bird damage on overhead lines to solve the above problems.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An insulating cover for preventing bird damage on overhead lines of the utility model includes an insulator cover and two symmetrically arranged wire sheaths connected to the insulator cover. A locking component is connected to the end of the wire sheath away from the insulator cover; several support rods are connected to the top of the insulator cover, a universal component is connected to the top of the support rods, and a triangular top plate is connected to the top of the universal component. There are gaps between the top plates, and the spacing distances between adjacent two top plates are equal.

[0007] Further, an embedding hole is opened at the bottom of the wire sheath, and the wire is clamped into the wire sheath through the embedding hole.

[0008] Further, the locking component includes two symmetrically arranged deformation plates connected to the end of the wire sheath. Arc-shaped clamping plates are respectively connected to the other ends of the two deformation plates. Semi-threaded columns are respectively connected to the tops of the two arc-shaped clamping plates. The two semi-threaded columns are symmetrically arranged. There is a gap between the two semi-threaded columns. The two semi-threaded columns are combined into a complete frustum-shaped spiral rod. A fastening nut is threadedly connected to the external threads of the two semi-threaded columns.

[0009] Further, the universal joint assembly includes a universal ball connected to the top of the support rod and a universal socket connected to the bottom surface of the top plate, and the universal socket is sleeved on the universal ball.

[0010] Further, a pointed cone is provided at the center of the top surface of the top plate.

[0011] Compared with the prior art, the beneficial technical effects of the present utility model are as follows:

[0012] The structure of the present utility model is simple and the cost is low. The device can be firmly fixed on the wire and the insulator through the locking assembly, and the unstable top plate is arranged to prevent the birds from standing stably on the top plate, thus preventing the birds from perching.

Detailed Description of the Invention

[0019] As Figures 1-4 shown, an anti-bird damage insulation cover for overhead lines includes an insulator cover 1 and two symmetrically arranged wire sheaths 2 connected to the insulator cover 1. An embedding hole 5 is formed at the bottom of the wire sheath 2, and the wire is clamped into the wire sheath 2 through the embedding hole 5.

[0020] The locking assembly includes two symmetrically arranged deformation plates 6 connected to the end of the wire sheath 2. Arc-shaped clamping plates 12 are respectively connected to the other ends of the two deformation plates 6. Semi-threaded columns 7 are respectively connected to the tops of the two arc-shaped clamping plates 12. The two semi-threaded columns 7 are symmetrically arranged with a gap therebetween. The two semi-threaded columns 7 are combined into a complete frustum-shaped screw rod. A fastening nut 8 is threadedly connected to the external threads of the two semi-threaded columns 7. After the insulator cover 1 and the wire sheath 2 are both installed, by rotating the fastening nut 8, the two semi-threaded columns 7 are driven, so as to drive the two arc-shaped clamping plates 12 to continuously approach and clamp the wire.

[0021] A plurality of support rods 3 are connected to the top of the insulator cover 1. A universal joint assembly is connected to the top of the support rod 3. A triangular top plate 4 is connected to the top of the universal joint assembly. The universal joint assembly includes a universal ball 9 connected to the top of the support rod 3 and a universal socket 10 connected to the bottom surface of the top plate 4. The universal socket 10 is sleeved on the universal ball 9. There are gaps between all the top plates 4, and the spacing distances between two adjacent top plates 4 are equal. By arranging the universal joint assembly, the top plate 4 can rotate freely under the action of an external force. When a bird lands on the top plate 4, the top plate 4 rotates under pressure, and the bird will be frightened by the rotation of the top plate 4 and fly away.

[0022] A sharp cone 11 is arranged at the center position of the top surface of the top plate 4 to further prevent birds from landing on the top plate 4.

[0023] The above embodiments are only described for the preferred mode of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solution of the present invention shall fall within the protection scope determined by the claims of the present invention.
