Abstract

An improved rigid insulating sleeve for bird protection on a single porcelain insulator for live installation on utility poles 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, which covers the top of the insulator. The lower end of the porcelain insulator sleeve has an opening corresponding to the upper part of the insulator. The lower edge of the wire sleeve has a slit that penetrates the opening at the lower end of the porcelain insulator 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. A clamp conforming to 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. The advantages of this invention are: it can be applied to wires of both large and small diameters, greatly improving applicability, and reducing the elasticity requirements of the raw materials, allowing the use of a harder insulating material.

Description

Technical Field

[0001] The invention relates to a single-porcelain-bottle bird-proof hard insulating sheath for electric poles that can be installed under power. The sheath is mainly used for being installed on the top of a single porcelain bottle arranged on an electric pole and on the electric wires supported thereby, so as to prevent the intrusion of rain and snow and the damage to the binding wires and the electric wires between the top of the porcelain bottle and the electric wires caused by birds building nests. Background Art

[0002] The power line is generally erected on a pole 16, a cross arm 15 is fixed on the pole 16, and a wire 13 is supported on the cross arm 15 through a porcelain bottle 14 (see Fig.10 ). The wires are usually tied to the top of the porcelain bottle with binding wires (usually bare aluminum wires). The binding wires and adjacent wires are prone to corrosion under long-term rain and snow erosion, and in severe cases they will break; birds also often build nests or stay on the top of the porcelain bottle. Bird nests and bird excrement will cause corrosion damage to the binding wires and wires, which will have an adverse effect on the safe operation of the power lines.

[0003] In order to solve the above problems, I have invented a single porcelain bottle insulating sheath for electric poles that can be installed under power (application number CN202411434681.2, application date: 20241015). Its structure includes a porcelain bottle sleeve and a wire sleeve. A wire sleeve for wrapping the wire is connected to the opposite sides of the porcelain bottle sleeve for wrapping the top of the porcelain bottle. An opening corresponding to the upper part of the porcelain bottle is provided at the lower end of the porcelain bottle sleeve, and a slit that passes through the opening at the lower end of the porcelain bottle sleeve is provided at the lower side of the wire sleeve. A downwardly extending butt joint edge is connected to each side of the slit, and it is characterized in that a mounting plate is provided on the porcelain bottle sleeve, and a mounting hole is provided on the mounting plate; the cross-section of the butt joint edges on both sides is in an eight-shaped shape, and the minimum spacing between the butt joint edges on both sides matches the diameter of the wire; the insulating sheath is made of a hard and elastic insulating material. The disadvantages of this insulating sheath are: poor applicability, the insulating material needs to have appropriate elasticity to be inserted into the wire, and the material requirements are high; the butt edge needs to cooperate with the wire for installation. If the wire is thin (less than the minimum spacing between the butt edges on both sides), the wire is easy to fall off; if the wire is thick, it cannot be inserted into the butt edge, and a suitable insulating sheath needs to be replaced, which brings inconvenience to use. Summary of the invention

[0004] The invention provides an improved single-porcelain-bottle bird-proof hard insulating sheath for electric poles which can be installed under power, so as to solve the above problems existing in the existing insulating sheaths.

[0005] The technical solution of the present invention is: an improved single-porcelain bottle bird-proof hard insulating sheath for electric poles that can be installed under power, comprising a porcelain bottle sheath and a wire sheath, wherein a wire sheath for wrapping the wire is connected to opposite sides of the porcelain bottle sheath for wrapping the top of the porcelain bottle, an opening corresponding to the upper part of the porcelain bottle is provided at the lower end of the porcelain bottle sheath, a slit that passes through the opening at the lower end of the porcelain bottle sheath is provided at the lower side of the wire sheath, and downwardly extending butt joint edges are connected to the two sides of the slit, a mounting plate is provided on the porcelain bottle sheath, and a mounting hole is provided on the mounting plate; the cross-sections of the butt joint edges on both sides are in an eight-shaped shape, and are characterized in that a clamping plate that matches the shape of the butt joint edges is connected to opposite sides of the two butt joint edges through an elastomer; the insulating sheath is made of a hard insulating material.

[0006] The advantages of the present invention are: since the clamping plates are connected by elastic bodies on the two opposite sides of the butt joint, the clamping plates can be elastically translated, the distance between the two clamping plates can be made smaller, and the wire with a larger diameter can be loaded between the two clamping plates by compressing the spiral spring behind the clamping plates; and after the wire with a smaller diameter is loaded, the clamping plates are restored by the spiral spring, which can prevent the wire from falling off. Therefore, the insulating sheath can be applied to wires with larger or smaller diameters, greatly improving the applicability, and also reducing the requirements for the elasticity of the raw materials, and can be made of harder insulating materials.

DETAILED DESCRIPTION

[0018] See also Figure 1-Figure 5 The first embodiment of the improved single-porcelain bottle bird-proof hard insulating sheath for electric poles that can be installed under power, according to the present invention, comprises a porcelain bottle sheath 1 and a wire sheath 2. A wire sheath 2 for wrapping the wire is connected to the opposite sides of the porcelain bottle sheath 1 for wrapping the top of the porcelain bottle, an opening corresponding to the upper part of the porcelain bottle is provided at the lower end of the porcelain bottle sheath 1, a slit penetrating the opening at the lower end of the porcelain bottle sheath 1 is provided at the lower side of the wire sheath 2, and a butt joint 3 extending downward is connected to each side of the slit, a mounting plate 4 is provided at the top of the porcelain bottle sheath 1, and a mounting hole 41 is provided on the mounting plate 4; the cross-sections of the butt joint 3 on the opposite sides are in an eight-shaped shape.

[0019] The feature is that a clamping plate 5 matching the shape of the butt joint edge 3 is connected to opposite sides of the two butt joint edges 3 via an elastic body; and the insulating sheath is made of a hard insulating material.

[0020] The connection structure between the clamping plate 5 and the butt edge 3 of this embodiment is as follows: a row of multiple through holes 31 are provided on the butt edge 3, multiple plugs 51 corresponding to the through holes 31 are provided on the outer side of the clamping plate 5, and a conical petal flange (three or four petals, see Figure 6 ), 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. In order to make the top of the plug have radial contraction elasticity, a Y-shaped notch (through groove) or a cross groove passing through the diameter line is opened. The elastic body can be a coil spring 7, or other elastic bodies with the same function (such as a rubber tube). The coil spring 7 is sleeved on the root of the plug 51; the flange at the top of the plug 51 is radially compressed and passes through the through hole 31 and then recovers (stuck on the outside of the through hole 31), and the coil spring 7 is supported between the clamping plate 5 and the butt edge 3.

[0021] Raised ridges 52 may be provided at intervals on the inner side of the clamping plate 5 to increase the strength.

[0022] A reinforcing rib 6 is provided between the side of the top of the porcelain bottle sleeve 1 corresponding to the wire sleeve 2 and the upper side of the root of the wire sleeve 2. The reinforcing rib 6 can strengthen the supporting effect on the wire sleeve 2 to prevent the wire sleeve 2 from bending downward during installation.

[0023] See also Figure 7 The second embodiment of the present invention is different from the first embodiment in that the mounting plate 4 is arranged on one side of the porcelain bottle sleeve 1.

[0024] The mounting holes 41 provided on the mounting plate 4 of the present invention are (at least) two circular holes or 1-2 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.

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

[0026] The present invention can also provide a rainproof edge (not shown) at the lower end of the porcelain bottle sleeve 1 to improve the protection effect.

[0027] See also Figure 8 , is a mounting rod used in conjunction with the mounting plate 4, comprising: a connecting plate 8 bent (deflected) to one side is connected to the top of the insulating rod 12, and a convex column 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 through a handle bolt 10, and an anti-rotation mechanism 11 (such as a concave-convex structure that matches each other, or a structure similar to a spline) 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 easy use.

[0028] The porcelain bottle cover 1 and the electric wire cover 2 of the present invention are an integrated structure and are made of hard plastic (such as polycarbonate 2805) by injection molding.

[0029] See also Fig. 9 and Fig.10 During installation, the present invention inserts the boss 9 into the mounting hole 41 of the mounting plate 4 of the sheath, then lifts the sheath above the porcelain bottle 14, and pulls the insulating rod 12 downward to cover the sheath on the upper part of the porcelain bottle 14 and the wires 13 on both sides; finally, withdraws the boss 9 from the mounting hole 41 of the mounting plate to complete the installation.
