Description

Technical Field

[0001] The invention relates to a single porcelain bottle rain and snow proof and bird damage proof insulating sheath for electric poles which can be installed under power. 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 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.11 ). 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 invented a porcelain bottle insulation sheath for electric poles to prevent rain, snow and bird damage (CN202311330691.7, porcelain bottle insulation sheath for electric poles to prevent rain, snow and bird damage, publication number: CN117153502A, application date: 20231016), whose structure includes a porcelain bottle sheath and a wire sheath, and a wire sheath for wrapping the wires is connected on two opposite sides of the porcelain bottle sheath for wrapping the top of the porcelain bottle, and an opening corresponding to the upper part of the porcelain bottle is provided at the lower end of the porcelain bottle sheath, and a slit is provided on the lower side of the wire sheath, which is connected to the opening at the lower end of the porcelain bottle sheath, and a downwardly 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 the prior art are that during installation, the multiple locks between the butt joints at 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). It also needs to be manually installed after power is turned off, which brings inconvenience to use. Summary of the invention

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

[0005] The technical solution of the present invention is: a single porcelain bottle insulating sheath for electric poles that can be installed under power and is rainproof, snowproof and bird-proof, 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 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 present invention are: it is made of relatively hard material, and an eight-shaped opening capable of inserting the wire is reserved at the butt joint edge at the bottom of the wire sleeve, so that the entire sheath of the present invention can be installed downward from the top of the porcelain bottle and the adjacent wires using a mounting rod to support the mounting plate without cutting off the power supply, thereby facilitating the application, effectively isolating the wires from rain, snow and bird damage, avoiding corrosion damage to the binding wires and the wires, and ensuring the safe operation of the power line.

DETAILED DESCRIPTION

[0019] See also Figure 1-Figure 3 The first embodiment of the single porcelain bottle rain, snow and bird-proof insulating sheath for electric poles that can be installed under power, includes 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 that penetrates the opening at the lower end of the porcelain bottle sheath 1 is provided at the lower side of the wire sheath 2. A butt joint 3 extending downward is connected to each side of the slit. This embodiment has a top mounting plate 4 at the top 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 an eight-shaped shape, and the minimum spacing between the butt joint 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 3 on both sides can clamp the wire 13).

[0020] 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.

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

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

[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 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.

[0025] See also Figure 7 and Figure 8 , is a mounting rod used in conjunction with the mounting plate, 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 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 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.

[0026] The porcelain bottle cover 1 and the wire cover 2 of the present invention are an integrated structure, made of hard and elastic plastic (such as polyvinyl chloride) or rubber, and the material is selected so that the two ends of the cover are basically not bent downward during installation, so that 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 Fig.11 ).

[0027] When installing (see Figure 9-11 ), insert the boss 9 into the mounting hole 5 of the mounting plate of the sheath, then lift the sheath to the top of the porcelain bottle 14, and pull 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, withdraw the boss 9 from the mounting hole 5 of the mounting plate to complete the installation.
