Abstract
Description
Technical Field
[0001] This utility model relates to a rigid insulating sleeve for bird protection of a single porcelain insulator on a utility pole that can be installed while the pole is energized. It is mainly used to prevent rain and snow from entering the top of a single porcelain insulator and the power line supported by it, as well as 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. Power lines 13 are supported on the crossarms 15 via insulators 14 (see reference). Figure 10 Power lines are typically secured to the top of porcelain insulators with binding wire (usually bare aluminum wire). Over time, the binding wire and adjacent power lines are susceptible 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 power lines, adversely affecting the safe operation of the power lines.
[0003] To address the aforementioned problems, I have invented a single-porcelain insulated sleeve for power poles that can be installed while energized, providing protection against rain, snow, and birds (application number CN202411434681.2, application date: 20241015). Its structure includes a porcelain insulator sleeve and a power line sleeve. A power line sleeve for wrapping the power line is connected to each opposite side of the porcelain insulator sleeve used to wrap the top of the porcelain insulator. An opening corresponding to the upper part of the porcelain insulator is provided at the lower end of the porcelain insulator sleeve. A slit penetrating the lower opening of the power line sleeve is provided at the lower side of the power line sleeve. Downward-extending mating edges are connected to each side of the slit. The sleeve is characterized by a mounting plate with mounting holes on it; the cross-section of the mating edges on both sides is V-shaped, and the minimum distance between the mating edges matches the diameter of the power line; 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 be inserted into the power line, which places high demands on the material; the mating edges need to match the power line for installation, and if the power line is thin (less than the minimum distance between the mating edges on both sides), the power line is prone to falling off; if the power line is thick, it cannot be inserted into the mating edges, requiring the replacement of a suitable insulating sleeve, which causes inconvenience in use. Summary of the Invention
[0004] This invention provides a rigid insulating sleeve for electric pole porcelain insulators that is protected against bird damage, rain, and snow and can be installed while the pole is energized, in order to solve the aforementioned problems of existing insulating sleeves.
[0005] The technical solution of this utility model is: a rigid insulating sleeve for a porcelain insulator on a utility pole that can be installed while energized, protecting against bird damage, rain, and snow. It includes a porcelain insulator sleeve and a power line sleeve. A power line sleeve for wrapping the power line is connected to each of the opposite sides of the porcelain insulator sleeve used to wrap the top of the porcelain insulator. An opening corresponding to the upper part of the porcelain insulator is provided at the lower end of the porcelain insulator sleeve. A slit penetrating the opening at the lower end of the porcelain insulator sleeve is provided on the lower side of the power line sleeve. A downwardly extending mating edge is connected to each side of the slit. A mounting plate with mounting holes is provided on the porcelain insulator sleeve. The cross-section of the mating edges on the opposite sides is V-shaped. The key feature is that a clamping plate matching the shape of the mating edge is connected to the inner side of one of the mating edges via an elastic body. The insulating sleeve is made of a rigid insulating material.
[0006] The advantages of this invention are as follows: Because a clamping plate is connected to the inner side of one mating edge via an elastic body, the clamping plate can move elastically. The distance between the clamping plate and the opposite mating edge can be made smaller. Larger diameter power wires can be inserted between the clamping plate and the opposite mating edge by compressing the helical spring behind the clamping plate; while smaller diameter power wires, after being inserted, are prevented from falling off by the helical spring restoring the clamping plate. Therefore, this insulating sleeve is suitable for power wires of both large and small diameters, greatly improving its applicability and reducing the elasticity requirements of the raw materials, allowing for the use of harder insulating materials. This invention only installs a clamping plate on the inner side of one mating edge, which simplifies the structure compared to installing clamping plates on both sides, and avoids the clamping gap on both sides being too small, thus preventing interference with the insertion of the power wire.

[0018] See Figures 1-5 The first embodiment of this utility model is a rigid insulating sleeve for a porcelain insulator on a utility pole that can be installed while energized, protecting against bird damage, rain, and snow. It includes a porcelain insulator sleeve 1 and a power line sleeve 2. A power line sleeve 2 for wrapping the power line is connected to each of the opposite sides of the porcelain insulator sleeve 1, which is used to wrap the top of the porcelain insulator. The lower end of the porcelain insulator sleeve 1 has an opening corresponding to the upper part of the porcelain insulator. The lower side of the power line sleeve 2 has a slit that communicates with the opening at the lower end of the porcelain insulator sleeve 1. A downwardly extending mating edge 3 is connected to each side of the slit. A mounting plate 4 is provided at the top of the porcelain insulator sleeve 1. The mounting plate 4 has a mounting hole 41. The cross-section of the mating edge 3 on the opposite sides is V-shaped.
[0019] The feature is that a clamping plate 5, which matches the shape of the mating edge 3, is connected to the inner side of the mating edge 3 by an elastic body.
[0020] The connection structure between the clamping plate 5 and the mating edge 3 in this embodiment is as follows: a row of multiple (three in the figure) through holes 31 is provided on the mating edge 3 on which the clamping plate 5 is installed; multiple plugs 51 corresponding to the through holes 31 are provided on the outside of the clamping plate 5; and a conical petal flange (three or four petals, see [reference]) is provided at the top of the plug 51. Figure 6The maximum outer diameter of the petal-shaped 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, it has a Y-shaped notch (through groove) or a cross groove passing through the diameter line. 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 be 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.
[0021] Protruding ribs 52 can be provided at intervals on the inner side of the clamping plate 5 to increase strength.
[0022] A reinforcing rib 6 is provided between the top of the porcelain insulator sleeve 1 and the side corresponding to the power line sleeve 2, and the top of the root of the power line sleeve 2. The reinforcing rib 6 can strengthen the support of the power line sleeve 2 and prevent the power line sleeve 2 from bending downward during installation.
[0023] See Figure 7 This is the second embodiment of the present utility model. The difference from the first embodiment is that the mounting plate 4 is located on one side of the porcelain bottle sleeve 1.
[0024] The mounting holes 41 on the mounting plate 4 of this invention are (at least) two round holes or 1-2 non-circular holes (such as elongated holes or square holes). The purpose of providing two round holes or non-circular holes is to provide stable support during installation and prevent the sheath from swinging during installation.
[0025] An outer flange 21 may also be provided at the outer end of the power line sleeve 2 (or not provided) to increase the strength of the outer end of the power line sleeve 2.
[0026] This utility model can also provide a rainproof edge (not shown) at the lower end of the porcelain bottle sleeve 1 to improve the protective effect.
[0027] See Figure 8 The mounting rod is used in conjunction with the mounting plate 4 and includes: a connecting plate 8 that bends (deflects) to one side and is connected to the top of the insulating rod 12; a protrusion 9 corresponding to the mounting hole 41 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 is adjusted by the handle bolt 10 for ease of use. The insulating rod 12 can be made of multiple sections coaxially connected by threads or telescopic mechanisms (such as the telescopic structure of a trekking pole).
[0028] The ceramic bottle sleeve 1 and the power line sleeve 2 of this utility model are an integral structure, and are made of rigid plastic (such as polycarbonate 2805) by injection molding.
[0029] See Figure 9 and Figure 10 During installation, the protruding post 9 is inserted into the mounting hole 41 of the mounting plate 4 of the sheath, then the sheath is lifted above the porcelain insulator 14, and the insulating rod 12 is pulled down to cover the upper part of the porcelain insulator 14 and the power lines 13 on both sides; finally, the protruding post 9 is removed from the mounting hole 41 of the mounting plate 4 to complete the installation.
