Description

Technical Field

[0001] This utility model relates to a rigid insulating sleeve for bird protection on a single porcelain insulator that can be installed on a power pole while 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. Wires 13 are supported on the crossarms 15 via 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 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 wire sleeve. A wire sleeve for wrapping the wire is connected to each opposite side of the porcelain insulator sleeve used to cover 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 porcelain insulator sleeve is provided at the lower side of the wire sleeve. Downward-extending mating edges are connected to each side of this 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 on both sides matches the diameter of the wire; 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 wire, which places high demands on the material; the mating edges need to match the wire for installation, and if the wire is thin (less than the minimum distance between the mating edges on both sides), the wire is prone to falling off; if the wire 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 an improved rigid insulating sleeve for single porcelain insulators on utility poles that can be installed while energized, to prevent bird damage and solve the aforementioned problems of existing insulating sleeves.

[0005] The technical solution of this utility model is: an improved rigid insulating sleeve for bird protection on a single porcelain insulator of a utility pole that can be installed while energized, comprising a porcelain insulator sleeve and a wire sleeve. A wire sleeve for wrapping the wire 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 opening at the lower end of the porcelain insulator sleeve is provided at the lower side of the wire sleeve. A downwardly extending butt joint 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 butt joint on both sides is V-shaped. The characteristic feature is that a clamp matching the shape of the butt joint is connected to each opposite side of the two butt joints 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 The present invention discloses a first embodiment of an improved rigid insulating sleeve for a single porcelain insulator on a utility pole that can be installed while energized. The sleeve includes a porcelain insulator sleeve 1 and a wire sleeve 2. A wire sleeve 2 for wrapping the wire is connected to each opposite side 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 wire 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, and mounting holes 41 are provided on the mounting plate 4. The cross-section of the mating edges 3 on the opposite sides is V-shaped.

[0019] The invention is characterized in that, on each of the two mating edges 3, a clamping plate 5 that matches the shape of the mating edge 3 is connected by an elastic body on the opposite side; the insulating sleeve is made of a rigid insulating material.

[0020] 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 6The 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.

[0021] The inner side of the clamping plate 5 may be provided with protruding ribs 52 at intervals 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 wire sleeve 2, and the top of the root of the wire sleeve 2. The reinforcing rib 6 can strengthen the support of the wire sleeve 2 and prevent the wire sleeve 2 from bending downward during installation.

[0023] See Figure 7 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.

[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 ensure stable support during installation and prevent the sheath from swinging.

[0025] An outer flange 21 may also be provided at the outer end of the wire sleeve 2 (or not provided) to increase the strength of the outer end of the wire 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 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 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.

[0028] The ceramic bottle sleeve 1 and the wire 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 wires 13 on both sides; finally, the protruding post 9 is removed from the mounting hole 41 of the mounting plate to complete the installation.
