Description

Technical Field

[0001] This utility model relates to the field of insulator technology, and in particular to an insulator structure that prevents birds from pecking at it. Background Technology

[0002] Numerous real-world examples demonstrate that birds peck at composite insulators during their operation, causing damage. Research indicates that bird pecking typically occurs before the power equipment is operational or at the end with the lowest absolute electric field. Bird pecking can increase the likelihood of localized discharge on the insulator surface, leading to reduced creepage distance, flashover, and brittle fracture of exposed core rods, thus affecting the performance of the composite insulator. Common measures to address this include installing insulator protective covers or nets during power equipment construction, or installing large-diameter sheaths near structures with low electric field values. However, current measures cannot completely prevent this from happening; birds still curiously peck at the covering components of polymer insulators through protective covers or nets, damaging the polymer insulators. Summary of the Invention

[0003] This utility model addresses the problems of existing technologies by providing a bird-proof insulator structure. The structure is novel, directly protecting the insulator body through a protective sheath, preventing direct damage from bird pecks. Birds cannot peck through the outer hard sheath, thus protecting the insulator body. Furthermore, the sleeve rod is fitted around the outer periphery of the core rod and detachably connected to it, facilitating individual assembly and disassembly of the insulator skirt assembly, simplifying cleaning and maintenance, and allowing for convenient daily use by operators to extend the insulator length.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model provides a bird-proof insulator structure, which includes a core rod and multiple shed insulation groups. The multiple shed insulation groups are sequentially and equally spaced around the outer periphery of the core rod along its length. One end of the core rod is provided with a ball-head connector, and the other end of the core rod is provided with a ball-and-socket connector. The ball-head connector and the ball-and-socket connector are correspondingly connected. Each shed insulation group includes a sleeve rod and a shed body fitted around the outer periphery of the sleeve rod. A shed sheath is fitted around the outer periphery of the shed body. The sleeve rod is fitted around the outer periphery of the core rod and is detachably connected to the core rod.

[0006] The ball head connecting part is provided with a snap-fit ​​ball head, and the ball socket connecting part is provided with a snap-fit ​​groove. The snap-fit ​​ball head and the snap-fit ​​groove are engaged and snap-fitted together. The snap-fit ​​groove is provided with a first elastic protrusion for pressing the snap-fit ​​ball head tightly.

[0007] The sleeve rod is hollow, and recesses are provided on both sides of the inner wall of the sleeve rod. Multiple locking components are provided at equal intervals along the length of the core rod. Each locking component includes two second elastic protrusions, which are respectively provided on both sides of the core rod.

[0008] The Shore hardness of the umbrella skirt body is 60-70A.

[0009] The hardness of the umbrella skirt sheath is 70-80D.

[0010] The radius of the umbrella skirt sheath is 20-22 mm.

[0011] The beneficial effects of this utility model are:

[0012] This utility model features a novel structure. Its key characteristic is that a protective sleeve is directly fitted around the outer periphery of the insulator's skirt body. This sleeve directly protects the skirt body, preventing direct damage from bird pecks. Birds cannot penetrate the hard outer sleeve, thus protecting the insulator's skirt body. Furthermore, the sleeve rod is fitted around the outer periphery of the core rod and detachably connected to it, facilitating individual assembly and disassembly of the skirt insulation assembly, and simplifying cleaning and maintenance. Additionally, when it is necessary to connect two or more insulator structures according to this application embodiment into a string, the ball-head connection of one insulator structure can be correspondingly connected to the ball-socket connection of another insulator structure, enabling the connection of two or more insulator structures into a string. This facilitates daily use by operators to extend the insulator length. Attached Figure Description

One end of the core rod 1 is provided with a ball-head connecting part 3, and the other end of the core rod 1 is provided with a ball-and-socket connecting part 4. The ball-head connecting part 3 and the ball-and-socket connecting part 4 are correspondingly connected. The umbrella skirt insulation group 2 includes a sleeve rod 5 and an umbrella skirt body 6 sleeved around the outer periphery of the sleeve rod 5. An umbrella skirt sheath 7 is sleeved around the outer periphery of the umbrella skirt body 6. The sleeve rod 5 is sleeved around the outer periphery of the core rod 1 and is detachably connected to the core rod 1. Preferably, the umbrella skirt sheath 7 is made of a rigid material. Specifically, this utility model has a novel structure. Its key feature is that a skirt sheath 7 is directly fitted around the outer periphery of the insulator's skirt body 6.

When the ball head connecting part 3 of one insulator structure is engaged and connected with the ball socket connecting part 4 of another insulator structure, the snap-fit ​​ball head 8 is snapped into the snap-fit ​​groove 9 to achieve connection. Furthermore, the first elastic protrusion 10 in the snap-fit ​​groove 9 presses the snap-fit ​​ball head 8 against the snap-fit ​​groove 9, thereby improving the tightness of the connection between the snap-fit ​​ball head 8 and the snap-fit ​​groove 9 and improving the structural stability after connection.
