Description

Technical Field

[0001] This utility model relates to an improved rigid insulating sleeve for double porcelain insulators on utility poles that can be installed while energized. It is mainly used to install on the top of two parallel porcelain insulators on a utility pole and on the power line supported by them, to prevent rain and snow from entering and to prevent damage to the binding wire between the top of the porcelain insulator and the power line from birds building nests. Background Technology

[0002] Power lines are typically erected on utility poles 16, with crossarms 15 fixed to the poles 16. The power lines 13 are supported on the crossarms 15 by two parallel porcelain insulators 14 (see reference). Figure 10 Electrical wires are typically tied to the top of porcelain insulators using binding wire (usually bare aluminum wire). Over time, the binding wire and adjacent wires are prone to corrosion from rain and snow, which can lead to breakage in severe cases. Birds also frequently nest or perch on the top of the insulators, and their nests and droppings can corrode and damage the binding wire and the wires, adversely affecting the safe operation of the power lines.

[0003] To address the aforementioned problems, I have invented a double-porcelain insulated sleeve for power poles with adjustable spacing during live installation (application number CN202411434727.0, application date: 20241015). Its structure includes two porcelain insulator sleeves for covering the top of the insulators. Each insulator sleeve has an outer wire sleeve on one side for covering the power wire, and a telescopic wire sleeve on the other side of each insulator sleeve that is aligned with and symmetrically arranged with the outer wire sleeve. The lower end of each insulator sleeve has an opening corresponding to the upper part of the insulator, and the lower edges of the outer wire sleeve and the telescopic wire sleeve have openings that penetrate the lower end of the insulator sleeve. The insulating sleeve has a through slit, with downwardly extending mating edges on both sides. The telescopic wire sleeve consists of an outer wire sleeve and an inner wire sleeve. The end of the outer wire sleeve is coaxially fitted onto the outside of the end of the inner wire sleeve, allowing for axial expansion and contraction. Each porcelain insulator sleeve has a mounting plate with mounting holes. The cross-section of the mating edges on both sides is V-shaped. The minimum distance between the mating edges on both sides of the outer and inner wire sleeves matches the diameter of the wire. The minimum distance between the mating edges on both sides of the outer wire sleeve matches the outer diameter of the inner wire sleeve. The insulating sleeve is made of a rigid yet elastic insulating material. The disadvantages of this insulating sleeve are: poor applicability, requiring the insulating material to have suitable elasticity to clamp the wire, thus placing high demands on the material; the mating edges need to match the wire for installation, and if the wire is thin (smaller than the minimum distance between the mating edges), the wire is prone to detachment; if the wire is thick, it cannot be clamped into the mating edges, requiring replacement with a suitable insulating sleeve, causing inconvenience in use. Summary of the Invention

[0004] This invention provides an improved rigid insulating sleeve for double porcelain insulators on utility poles that can be installed while the power is on, to prevent bird damage and solve the above-mentioned problems existing in the prior art.

[0005] The technical solution of this utility model is as follows: an improved rigid insulating sleeve for bird protection on a utility pole with double porcelain insulators, capable of being installed while energized. It includes two porcelain insulator sleeves for wrapping the top of the insulators. On one side of each insulator sleeve is an outer wire sleeve for wrapping the electrical wire, and on the other side of each insulator sleeve are retractable wire sleeves that are symmetrically arranged and interlocked with each other. An opening corresponding to the upper part of the insulator is provided at the lower end of each insulator sleeve. A slit penetrating the opening at the lower end of the outer wire sleeve and the retractable wire sleeve is provided at the lower edge of both the outer wire sleeve and the retractable wire sleeve. A downwardly extending mating edge is provided on each side of the slit. The retractable wire sleeve consists of an outer wire sleeve and an inner wire sleeve. The end of the outer wire sleeve is coaxially fitted onto the outside of the end of the inner wire sleeve, allowing for axial extension and retraction. An mounting plate with mounting holes is provided on each insulator sleeve. The cross-section of the mating edges on both sides is V-shaped. The characteristic feature is that a clamp matching the shape of the mating edge is connected to each of the two mating edges on opposite sides via an elastic body. The insulating sleeve is made of a rigid insulating material.

[0006] The advantages of this invention are: because each of the two mating edges is connected to a clamping plate by an elastic body on its opposite side, the clamping plates can move elastically, allowing for a smaller distance between the two clamping plates. Larger diameter wires can be inserted between the two clamping plates by compressing the helical springs behind them; while smaller diameter wires, after being inserted, are released by the helical springs, preventing them from falling out. Therefore, this insulating sheath is suitable for both large and small diameter wires, greatly improving its applicability and reducing the elasticity requirements of the raw materials, allowing for the use of harder insulating materials.

[0018] See Figures 1-5 This utility model discloses an improved first embodiment of a rigid, bird-damage-proof double-porcelain insulator sleeve for power poles capable of live installation. It includes two porcelain insulator sleeves 1 for covering the top of the porcelain insulators. Each porcelain insulator sleeve 1 has an outer wire sleeve 2 on one side for covering the power wire, and a telescopic wire sleeve on the other side of each porcelain insulator sleeve 1 that is symmetrically arranged and interlocked with the outer wire sleeve 2. The lower end of each porcelain insulator sleeve 1 has an opening corresponding to the upper part of the porcelain insulator. The lower edges of the outer wire sleeve 2 and the telescopic wire sleeve have slits that penetrate the opening at the lower end of the porcelain insulator sleeve 1. On both sides of these slits… Each has a downwardly extending mating edge 3; the telescopic wire sleeve consists of a wire outer sleeve 22 and a wire inner sleeve 23, the end of the wire outer sleeve 22 is coaxially fitted on the outside of the end of the wire inner sleeve 23, and they can slide axially to each other; a mounting plate 4 is provided at the top of each porcelain insulator sleeve 1, and a mounting hole 41 is provided on the mounting plate 4; the cross-section of the mating edge 3 on both sides is V-shaped, characterized in that, on each of the two mating edges 3 opposite to each other, a clamping plate 5 that matches the shape of the mating edge 3 is connected by an elastic body; the insulating sleeve is made of a rigid insulating material.

[0019] The connection structure between the clamping plate 5 and the mating edge 3 in this embodiment is as follows: a row of multiple through holes 31 is provided on the mating edge 3, and multiple plugs 51 corresponding to the through holes 31 are provided on the outer side of the clamping plate 5. A conical petal-shaped flange (three or four petals, see [reference]) is provided at the top of the plug. Figure 7 The maximum outer diameter of the flange is slightly larger than the diameter of the through hole 31. The plug 51 can be hollow or solid, with a conical outer flange at the top, the diameter of which is larger than the root of the plug 51. To give its top radial contraction elasticity, a Y-shaped notch (through groove) or cross groove passing through the diameter line is opened. The elastic body can be a helical spring 7, or other elastic bodies with the same function (such as rubber tubing). The helical spring 7 is fitted at the root of the plug 51; after the flange at the top of the plug 51 is radially compressed, it passes through the through hole 31 and then returns to its original position (locked on the outside of the through hole 31). The helical spring 7 is supported between the clamping plate 5 and the mating edge 3.

[0020] The inner side of the clamping plate 5 may be provided with protruding ribs 52 at intervals to increase strength.

[0021] See Figure 6 The second embodiment of this utility model differs from the first embodiment in that the mounting plate 4 is located on one side of the porcelain bottle sleeve 1.

[0022] The mounting plate 4 of this utility model has at least two circular holes or one or two non-circular holes (such as elongated holes or square holes). The purpose of providing two circular holes or non-circular holes is to provide stable support during installation and prevent the sheath from swinging.

[0023] Reinforcing ribs 6 can also be provided between the top of the two porcelain insulator sleeves 1 and the top of the root of the adjacent outer wire sleeve 2. The reinforcing ribs 6 can strengthen the support of the outer wire sleeve 2 and prevent the outer wire sleeve 2 from bending downward during installation.

[0024] This utility model may also provide an outer flange 21 (or not) at the outer end of the outer wire sleeve 2, which can increase the strength of the outer end of the outer wire sleeve 2.

[0025] A rainproof rim (not shown) can also be provided at the lower end of the porcelain bottle sleeve 1 to improve the protective effect.

[0026] The present invention has one ceramic bottle sleeve 1 and its two outer wire sleeves 2 and wire outer sleeves 22 as an integral structure, and another ceramic bottle sleeve 1 and its two outer wire sleeves 2 and wire inner sleeves 23 as an integral structure, which are made of rigid plastic (such as polycarbonate 2805) by injection molding.

[0027] See Figure 8 and Figure 9This utility model also includes a mounting rod used in conjunction with the mounting plate 4. The mounting rod includes a connecting plate 8 that is bent (deflected) to one side and connected to the top of the insulating rod 12. A protrusion 9 corresponding to the mounting hole 41 of the mounting plate 4 is provided on one side of the connecting plate 8. One end of the connecting plate 8 is connected to the top of the insulating rod 12 via a handle bolt 10. An anti-rotation mechanism 11 (such as a mating concave-convex structure or a spline-like structure) is provided between the connecting plate 8 and the insulating rod 12. The angle between the connecting plate 8 and the insulating rod 12 can be adjusted using the handle bolt 10 for ease of use.

[0028] See Figures 8-10 During installation, insert the protruding post 9 into the mounting hole 41 of the mounting plate 4 with an insulating sheath containing the inner wire sleeve 23, and then lift the insulating sheath to... Figure 9 Above the porcelain insulator 14 on the right, pull down the insulating rod 12 to place the insulating sleeve over the upper part of the porcelain insulator 14 and the wires 13 on both sides; then remove the protruding post 9 from the mounting hole 41 of the top mounting plate 4 to complete the installation of the right half of the insulating sleeve. Then, use the same method to install the left half of the insulating sleeve on the porcelain insulator 14 on the left, and put the outer wire sleeve 22 of this half of the insulating sleeve over the inner wire sleeve 23 of the already installed insulating sleeve. This completes the installation of a complete set of insulating sleeves, as shown below. Figure 10 As shown.
