Description

Technical Field

[0001] The invention relates to a double-porcelain-bottle bird-proof insulating sheath for electric poles with adjustable spacing and capable of being installed live. The sheath is mainly used for being installed on the tops of two parallel porcelain bottles on electric poles and 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. Background Art

[0002] The power lines are generally erected on a pole 16, on which a cross arm 15 is fixed, and on which two porcelain bottles 14 arranged in parallel support the wires 13 (see Figure 13 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 double porcelain bottle insulation sheath for electric poles to prevent rain, snow and bird damage (CN2022421345684.4), which includes two porcelain bottle sleeves, which are connected to each other on opposite sides of the porcelain bottle sleeves by a telescopic wire sleeve (a threaded tube is provided in the middle of the telescopic wire sleeve, which can be extended to a certain length), and a wire sleeve is provided on the other side of the porcelain bottle sleeve. 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 is provided below the wire sleeve and the middle wire sleeve, which is connected to the opening at the lower end of the porcelain bottle sleeve. A downwardly extending butt joint edge is connected to each side of the slit, and the butt joint edges on both sides are connected to each other by multiple spaced locks. The disadvantages of this prior art are: during installation, it is necessary to manually connect the multiple locks between the butt joint edges of the lower side of the wire sleeve, so it must be installed after the power is turned off; in addition, it is made of flexible plastic or rubber, which is easy to bend and cannot be supported and installed using an installation tool (installation rod). It also needs to be manually installed after the power is turned off, which brings inconvenience to use. Summary of the Invention

[0004] The invention provides a double-porcelain-bottle bird-damage-proof insulating sheath for electric poles with adjustable spacing and capable of being installed under power, so as to solve the above-mentioned problems existing in the prior art.

[0005] The technical solution of the present invention is: a double-porcelain bottle bird-proof insulating sheath for electric poles with adjustable spacing that can be installed under power, comprising two porcelain bottle covers for wrapping the top of the porcelain bottle, an outer wire cover for wrapping the wires on one side of each porcelain bottle cover, and a telescopic wire cover that butts against each other and is symmetrically arranged with the outer wire cover on the other side of each porcelain bottle cover; an opening corresponding to the upper part of the porcelain bottle is provided at the lower end of the porcelain bottle cover, a slit that passes through the opening at the lower end of the porcelain bottle cover is provided at the lower sides of the outer wire cover and the telescopic wire cover, and a butt joint edge extending downward is provided on each side of the slit , characterized in that the telescopic wire sleeve consists of a wire outer sleeve and a wire inner sleeve, the end of the wire outer sleeve is coaxially sleeved on the outside of the end of the wire inner sleeve, and can axially telescope and slide with each other; a mounting plate is provided on each 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 of the outer wire sleeve and the wire inner sleeve is matched with the diameter of the wire; the minimum spacing between the butt joint edges on both sides of the wire outer sleeve is matched with the outer diameter of the wire inner sleeve; the insulating sheath is made of hard and elastic insulating material.

[0006] The advantages of the present invention are: it is made of a relatively hard material, is provided with a mounting plate, and has an eight-shaped opening on the bottom edge of the wire cover for receiving the wire. Therefore, without power outage, the mounting plate can be supported by a mounting rod, and the two parts of the cover can be installed downward from the top of the two porcelain bottles and adjacent wires, respectively, from above. This facilitates application. The outer and inner wire covers are axially telescopically adjustable to accommodate applications with double porcelain bottles of varying spacing, thus improving adaptability. It effectively isolates the wire cover from rain, snow, and bird damage, protects the binding wires and wires from corrosion, and ensures the safe operation of the power line.

[0021] See also Figure 1-Figure 5The first embodiment of the double-porcelain bottle bird-proof insulating sheath for electric poles that can be installed live and has adjustable spacing includes two porcelain bottle sleeves 1 for wrapping the top of the porcelain bottle, an outer wire sleeve 2 for wrapping the wire is provided on one side of each porcelain bottle sleeve 1, and a telescopic wire sleeve that docks with each other and is symmetrically arranged with the outer wire sleeve 2 is provided on the other side of each porcelain bottle sleeve 1; an opening corresponding to the upper part of the porcelain bottle is provided at the lower end of the porcelain bottle sleeve 1, and a slit that passes through the opening at the lower end of the porcelain bottle sleeve 1 is provided at the lower side of the outer wire sleeve 2 and the telescopic wire sleeve, and a docking edge 3 extending downward is provided on each side of the slit. It is characterized in that the telescopic wire sleeve consists of an outer wire sleeve 22 and an inner wire sleeve 23, and the end of the outer wire sleeve 22 is coaxially sleeved on the outside of the end of the inner wire sleeve 23, and can axially telescope and slide relative to each other. This embodiment is provided with a top mounting plate 4 on each porcelain bottle sleeve 1, and a mounting hole 5 is provided on the top mounting plate 4. The cross-section of the butt joint edges 3 on both sides is 8-shaped. The minimum spacing between the butt joint edges 3 on both sides of the outer wire sleeve 2 and the inner wire sleeve 23 matches the diameter of the wire 10 (equal to or slightly smaller than the former, so that the butt joint edges 3 on both sides can clamp the wire 10). The minimum spacing between the butt joint edges 3 on both sides of the outer wire sleeve 22 matches the outer diameter of the inner wire sleeve 23 (equal to or slightly smaller than the latter, so that the outer wire sleeve 22 can be put on the outer wire sleeve 23 from above with sufficient clamping force).

[0022] See also Figure 6-Figure 9 The second embodiment of the present invention is different from the first embodiment in that the mounting plate is a side mounting plate 7 , which is provided on one side of the porcelain bottle sleeve 1 .

[0023] The mounting holes 5 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.

[0024] Reinforcing ribs 6 are provided on both sides of the top of one of the porcelain bottle housings 1, between the adjacent outer wire housing 2 and the upper base of the inner wire housing 23. Reinforcing ribs 6 are also provided on both sides of the top of the other porcelain bottle housing 1, between the adjacent outer wire housing 2 and the upper base of the outer wire housing 22. The reinforcing ribs 6 provide enhanced support for the outer wire housing 2, outer wire housing 22, and inner wire housing 23, preventing the housings from bending during installation.

[0025] The present invention may further provide an outer flange 21 (or not) on the outer end of the outer wire sleeve 2 to increase the strength of the outer end of the outer wire sleeve 2 .

[0026] A rainproof edge (not shown) may also be provided at the lower end of the porcelain bottle sleeve 1 to improve the protection effect.

[0027] The present invention comprises a porcelain bottle housing 1 and its outer wire housings 2 and outer wire housings 22 on both sides, and another porcelain bottle housing 1 and its outer wire housings 2 and inner wire housings 23 on both sides, which are integral structures. They are made of hard and elastic plastic (such as polyvinyl chloride) or rubber. The material is selected so that the two ends of the insulating housing do not bend downward during installation. The middle part of the insulating housing (mounting plate) can be supported by the mounting rod and can be smoothly installed on the upper part of the porcelain bottle 14 and the adjacent wire 13 (reference Figure 13 ).

[0028] See also Figure 10-12 The present invention also includes a mounting rod for use with the mounting plate. The mounting rod comprises: a connecting plate 8 that is bent (deflected) toward 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 (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 handle bolt 10 allows the angle between the connecting plate 8 and the insulating rod 12 to be adjusted for ease of use.

[0029] See also Figure 12 and Figure 13 During installation, insert the boss 9 into the mounting hole 5 of the top mounting plate 4 of an insulating sheath with an inner sheath 23 of the wire, and then lift the insulating sheath to Figure 13 Install the insulating sheath on the top of the porcelain bottle 14 on the right side and pull the insulating rod 12 downward to cover the insulating sheath on the top of the porcelain bottle 14 and the wires 13 on both sides; then withdraw the protruding column 9 from the mounting hole 5 of the top mounting plate 4 to complete the installation of the right half of the insulating sheath. Then use the same method to install the left half of the insulating sheath on the left porcelain bottle 14, and cover the wire outer sleeve 22 of this half of the insulating sheath on the outside of the wire inner sleeve 23 of the already installed insulating sheath. This completes the installation of a complete set of insulating sheaths, as shown in the figure below. Figure 13 shown.
