Abstract
Description
Technical Field
[0001] The present invention relates to a double-porcelain bottle hard insulating sheath equipped with elastic end sleeves that can be installed under power. The sheath is mainly used for being installed on the tops of two parallel porcelain bottles on a utility pole and the power lines supported by them to prevent the intrusion of rain and snow and the damage of birds' nests to the binding wires between the tops of the porcelain bottles and the power lines and the power lines. Background Art
[0002] The power line is generally erected on a pole 16, on which a cross arm 15 is fixed, and on which a power line 13 is supported by two parallel porcelain bottles 14 (see Figure 11 The power line 13 is typically tied to the top of the porcelain bottle 14 with a binding wire (typically made of bare aluminum wire). The binding wire and adjacent power lines are susceptible to corrosion under long-term rain and snow erosion, and in severe cases, they may break. Birds also often build nests or rest on the top of the porcelain bottle. Bird nests and bird droppings can corrode and damage the binding wire and power lines, adversely affecting the safe operation of the power line.
[0003] In order to solve the above problems, I have applied for an improved double-porcelain bottle bird-proof hard insulating sheath for electric poles that can be installed under power, the structure of which includes two porcelain bottle covers for wrapping the top of the porcelain bottle, an outer wire cover for wrapping the wire on one side of each porcelain bottle cover, and a telescopic wire cover that is butted against each other and 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, and a slit that passes through the opening at the lower end of the porcelain bottle cover is provided at the lower edge of the outer wire cover and the telescopic wire cover, and a downwardly extending butt joint edge is provided on each side of the slit; the telescopic wire cover consists of an outer wire outer sleeve and an inner wire inner sleeve, the end of the outer wire outer sleeve is coaxially sleeved on the outside of the end of the inner wire sleeve, and can axially telescope and slide with each other; a mounting plate is provided on each porcelain bottle cover, and a mounting hole is provided on the mounting plate; the cross-section of the butt joint edges on both sides is in the shape of a figure eight, and a splint that matches the shape of the butt joint edge is connected to the opposite side of the two butt joint edges through an elastomer.
[0004] The disadvantages of this insulating sheath are: since it is made of hard insulating material, the two ends of the wire sheath can easily cause damage (indentation, especially when the power line is swaying under the force of the wind) to the aluminum power line, affecting the safety of power transmission; the mounting plate is located at the top of the porcelain bottle sheath, deviating from the center of gravity of the half, and is prone to tilting and sliding during installation, causing trouble in use. Summary of the Invention
[0005] The present invention provides a double-porcelain-bottle hard insulating sheath equipped with elastic end sleeves which can be installed under power, so as to solve the above-mentioned problems existing in the prior art.
[0006] The technical solution of the present invention is: a double-porcelain bottle hard insulating sheath equipped with elastic end sleeves that can be installed under power, including two porcelain bottle sleeves for wrapping the top of the porcelain bottle, an outer wire sleeve for wrapping the wire is provided on one side of each porcelain bottle sleeve, and a telescopic wire sleeve that is butted against each other and symmetrically arranged with the outer wire sleeve is provided on the other side of each 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 that passes through the opening at the lower end of the porcelain bottle sleeve is provided at the lower side of the outer wire sleeve and the telescopic wire sleeve, and a downward-extending butt joint edge is provided on each side of the slit; the telescopic wire sleeve is composed of an outer wire sleeve and an inner wire sleeve, and the end of the outer wire sleeve is coaxially sleeved on the outside of the end of the inner wire sleeve, and can axially telescope and slide relative to each other. ; A butt joint edge identical to the butt joint edge is provided on the lower side of the wire outer sleeve and the wire inner sleeve, and the cross-sections of the butt joint edges on both sides of the outer wire sleeve and the butt joint edges on both sides of the wire outer sleeve and the wire inner sleeve are all in an eight-shaped shape; a splint matching the shape of the butt joint edge is connected to the inner side of the butt joint edge of the outer wire sleeve through an elastic body; a middle splint corresponding to the splint is connected to the opposite side of the two butt joint edges of the wire inner sleeve through an elastic body; the insulating sheath is made of a hard insulating material, and is characterized in that an elastic end sleeve covering the outer end of the outer wire sleeve is provided at the outer end of each of the outer wire sleeves; a mounting plate is provided at the top end of each of the outer wire sleeves, and a mounting hole is provided on the mounting plate.
[0007] The advantages of the present invention are that, by installing an elastic end sleeve at the outer end of each outer wire sleeve, the wires are protected from damage by the outer sleeve ends, extending the service life of the wires and improving the safety of power transmission. Only one mounting plate is provided on the outer wire sleeve (located in the middle or near the center of gravity), eliminating the need for auxiliary mounting plates. This simplifies the structure, saves costs, and prevents tilting during installation, making installation easier. BRIEF DESCRIPTION OF THE DRAWINGS
