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 8 Electrical wire 13 is typically tied to the top of the porcelain insulator with binding wire (usually bare aluminum wire). The binding wire and adjacent electrical wires are prone to corrosion under long-term rain and snow erosion, and may even break in severe cases. Birds also frequently build nests or perch on the top of the porcelain insulator; bird nests and bird droppings can corrode and damage the binding wire and electrical 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 utility poles that can be installed while energized, providing protection against rain, snow, and birds. Its structure includes a porcelain insulator sleeve and a wire sleeve. On opposite sides of the porcelain insulator sleeve (which covers the top of the insulator), a wire sleeve is connected to enclose the wire. 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. On each side of this slit, a downward-extending mating edge is connected. A mounting plate with mounting holes is provided on the porcelain insulator sleeve. The cross-section of the mating edges on both sides is V-shaped, and the minimum distance between the mating edges matches the diameter of the wire. On each opposite side of the two mating edges, an elastic body connects a clamping plate that matches the shape of the mating edge. This insulating sleeve is made of a rigid yet elastic insulating material. The disadvantage of this insulating sheath is that, because it is made of rigid insulating material, the two ends of the sheath are prone to causing dents (indentations) on the aluminum power lines, especially when the power lines sway under the force of the wind, which affects the safety of power transmission. Summary of the Invention

[0004] This invention provides a rigid insulating sleeve for a single porcelain insulator equipped with an elastic end sleeve that can be installed under energized conditions, thereby solving the aforementioned problems of existing insulating sleeves.

[0005] The technical solution of this utility model is: a rigid insulating sleeve for a single porcelain insulator equipped with elastic end sleeves, capable of being installed under power, comprising a porcelain insulator sleeve and an electrical wire sleeve. An electrical wire sleeve for wrapping the electrical 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 on the lower side of the electrical wire 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. The cross-section of the mating edges on the opposite sides is V-shaped. A clamp matching the shape of the mating edge is connected to each opposite side of the two mating edges via an elastic body. The insulating sleeve is made of a rigid insulating material. The characteristic feature is that an elastic end sleeve covering the outer end of each electrical wire sleeve is installed at its outer end.

[0006] The advantages of this utility model are: by installing an elastic end sleeve at the outer end of each wire sleeve, the wire is prevented from being damaged by the outer end of the wire sleeve, the service life of the wire is extended, and the safety of power transmission is improved.

[0016] See Figures 1-5 This utility model discloses an embodiment of a rigid insulating sleeve for a single porcelain insulator equipped with elastic end sleeves, capable of being installed under live conditions. It includes a porcelain insulator sleeve 1 and an electrical wire sleeve 2. An electrical wire sleeve 2 is connected to each opposite side of the porcelain insulator sleeve 1, which covers 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 edge of the electrical wire sleeve 2 has a slit that penetrates the opening at the lower end of the porcelain insulator sleeve 1. A downwardly extending mating edge 3 is connected to each side of this 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. On one side of the two mating edges 3 facing each other (… Figure 1 , Figure 3 and Figure 5 (as shown) or both sides ( Figure 4 (As shown) Each of the sections is connected by an elastic body to a clamp 5 (with a shape that matches the mating edge 3); the insulating sheath is made of a rigid insulating material. The above is the prior art.

[0017] The feature is that each of the wire sleeves 2 is provided with an elastic end sleeve 6 covering the outer end of the wire sleeve 2.

[0018] The elastic end sleeve 6 is made of rubber and its shape is designed to match the outer end shape of the wire sleeve 2. One end of the elastic end sleeve 6 is provided with a slot 61 that can be inserted into the outer end of the wire sleeve 2. The outer end of the wire sleeve 2 and the elastic end sleeve 6 can be bonded to each other with an adhesive (conventional material).

[0019] The connection structure between the clamping plate 5 and the mating edge 3 in this embodiment is based on existing technology: a row of multiple through holes is provided on the mating edge 3, and multiple plugs 51 corresponding to the through holes are provided on the outer side of the clamping plate 5. A conical petal-shaped flange (three or four petals) is provided at the top of the plug, the maximum outer diameter of which is slightly larger than the diameter of the through hole. 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 a cross groove passing through the diameter line is provided. The elastic body can be a helical spring 7, which is fitted onto 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 and then returns to its original position (locked on the outside of the through hole), and the helical spring 7 is supported between the clamping plate 5 and the mating edge 3.

[0020] The inner side of the clamping plate 5 may be provided with protruding ribs 52 at intervals to increase strength.

[0021] A reinforcing rib 22 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 22 can strengthen the support of the wire sleeve 2 and prevent the wire sleeve 2 from bending downward during installation.

[0022] 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.

[0023] An outer flange 21 can also be provided at the outer end of the wire sleeve 2 (or it can be omitted) to increase the strength of the outer end of the wire sleeve 2. In this case, the elastic end sleeve 6 is fitted onto the outer flange 21.

[0024] 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.

[0025] See Figure 6 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.

[0026] 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.

[0027] See Figure 7 and Figure 8During installation, the present invention firstly places an elastic end sleeve 6 on the outer end of each wire sleeve 2, and the two can be fixed together by applying adhesive; then insert the protruding post 9 into the mounting hole 41 of the mounting plate 4 of the sheath, then lift the sheath above the porcelain insulator 14, and pull down the insulating rod 12 to put the sheath on the upper part of the porcelain insulator 14 and the wires 13 on both sides; finally, remove the protruding post 9 from the mounting hole 41 of the mounting plate to complete the installation.
