Description

Technical Field

[0001] The utility model relates to a single-porcelain-bottle insulating sheath for electric poles that can be installed under power and is rainproof, snowproof, and bird-damage-proof. The insulating 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 caused by birds building nests between the top of the porcelain bottle and the electric wires. Background Art

[0002] The power lines are generally erected on electric poles 16, on which cross arms 15 are fixed, and on which electric wires 13 are supported by porcelain bottles 14 (see Figure 11 Wires are typically tied to the top of the porcelain bottle with binding wire (usually bare aluminum wire). This binding wire and adjacent wires are susceptible to corrosion from prolonged exposure to rain and snow, and in severe cases, can break. Birds also often nest or rest on the top of the porcelain bottle, and their nests and droppings can corrode and damage the binding wires and wires, adversely affecting the safe operation of the power lines.

[0003] In order to solve the above problems, I invented a porcelain bottle insulation sheath for utility poles to prevent rain, snow and bird damage (CN202311330691.7, porcelain bottle insulation sheath for utility poles to prevent rain, snow and bird damage, publication number: CN117153502A, application date: 20231016). Its structure includes a porcelain bottle cover and a wire cover. A wire cover for wrapping the wire is connected on each opposite side of the porcelain bottle cover 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 cover, and a slit is provided at the lower edge of the wire cover that passes through the opening at the lower end of the porcelain bottle cover. A downward-extending docking edge is connected to each side of the slit, and the docking edges on both sides are connected to each other by a plurality of spaced-apart locks. The disadvantages of this prior art are that, during installation, multiple locks between the butt joints on the bottom of the wire sleeve need to be manually connected to each other, so the power must be turned off before installation. In addition, it is made of flexible plastic or rubber, which is easy to bend and cannot be supported by installation tools (installation rods). Manual installation also requires power off, which brings inconvenience to use. Summary of the Invention

[0004] The utility model provides a single-porcelain-bottle rain, snow and bird-damage proof insulating sheath for a power pole that can be installed under power, so as to solve the above-mentioned problems in the prior art.

[0005] The technical solution of the utility model is: a single porcelain bottle insulation sheath for electric poles that can be installed under power to prevent rain, snow and bird damage, comprising a porcelain bottle sheath and a wire sheath, a wire sheath for wrapping the wires 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 on both sides of the slit, characterized in that 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 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.

[0006] The advantages of the utility model are: it is made of relatively hard material, and an eight-shaped opening that can be used to insert the wire is reserved at the butt joint edge of the lower side of the wire cover. Therefore, when the power is not cut off, the mounting plate can be supported by the mounting rod, and the entirety of the utility model cover can be installed downward from the top of the porcelain bottle and the adjacent wires, which is convenient for application, effectively isolates the wires from rain, snow and bird damage, avoids corrosion damage to the binding wires and the wires, and ensures the safe operation of the power line.

[0019] See also Figure 1-Figure 3 The utility model discloses a first embodiment of a single porcelain bottle insulating sheath for protecting against rain, snow and bird damage on a utility pole that can be installed under power, comprising a porcelain bottle sheath 1 and a wire sheath 2. A wire sheath 2 for wrapping the wire is connected to 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, and a slit that passes through the opening at the lower end of the porcelain bottle sheath 1 is provided at the lower side of the wire sheath 2. A downwardly extending butt joint 3 is connected to each side of the slit. This embodiment has a top mounting plate 4 at the top end of the porcelain bottle sheath 1, and a mounting hole 5 is provided on the top mounting plate 4. The cross-section of the butt joint 3 on both sides is in the shape of a figure eight, and the minimum spacing between the butt joint edges 3 on both sides matches the diameter of the wire 13 (equal or the former is slightly smaller than the latter, so that the butt joint edges 3 on both sides can clamp the wire 13).

[0020] A reinforcing rib 6 is provided between the top of the porcelain bottle sleeve 1 and the side 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 of the wire sleeve 2 and prevent the wire sleeve 2 from bending downward during installation.

[0021] See also Figure 4-Figure 6 The second embodiment of the utility model is a single porcelain bottle rain, snow and bird-proof insulating sheath for a telephone pole that can be installed under power. The difference from the first embodiment is that the mounting plate is a side mounting plate 7, which is provided on one side of the porcelain bottle sleeve 1.

[0022] The mounting holes 5 of the present invention provided on the top mounting plate 4 and the side mounting plate 7 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.

[0023] 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.

[0024] The utility model can also be provided with a rainproof edge (not shown) at the lower end of the porcelain bottle sleeve 1 to improve the protection effect.

[0025] See also Figure 7 and Figure 8 The mounting rod used in conjunction with the mounting plate comprises: a connecting plate 8, bent (deflected) to one side, connected to the top of an insulating rod 12. A protrusion 9 corresponding to the mounting hole 5 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 (e.g., a mating concave-convex structure or a spline-like structure) is provided between the connecting plate 8 and the insulating rod 12. The handle bolt 10 allows the angle between the connecting plate 8 and the insulating rod 12 to be adjusted for ease of use.

[0026] The utility model of the porcelain bottle cover 1 and the wire cover 2 is an integrated structure, made of hard and elastic plastic (such as polyvinyl chloride) or rubber, and the material is selected so that the ends of the cover are basically not bent downward during installation, and the mounting plate that can support the cover with the mounting rod can be smoothly installed on the upper part of the porcelain bottle 14 and the adjacent wire 13 (see Figure 11 ).

[0027] When installing (see Figures 9-11 ), insert the boss 9 into the mounting hole 5 of the mounting plate of the sheath, then lift the sheath above the porcelain bottle 14, and pull down the insulating rod 12 to put the sheath on the upper part of the porcelain bottle 14 and the wires 13 on both sides; finally, withdraw the boss 9 from the mounting hole 5 of the mounting plate to complete the installation.
