Description

Technical Field

[0001] The invention relates to a double-porcelain-bottle hard insulating sheath for electric poles with an auxiliary mounting plate and capable of being installed under power. The sheath is mainly used for being installed on the tops of two parallel porcelain bottles on electric poles and on power lines supported by the porcelain bottles 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 tops of the porcelain bottles and the electric wires. 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 Fig.12 ). The power line 13 is generally tied to the top of the porcelain bottle 14 with a binding wire (generally using exposed aluminum wire). The binding wire and the adjacent power lines are prone to corrosion under long-term rain and snow erosion, and may be disconnected in severe cases; birds often build nests or stay on the top of the porcelain bottle, and the bird nests and bird excrement may cause corrosion damage to the binding wire and the power line, which has an adverse effect on 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 (application number CN202520025976.8, application date: 20250107). Its structure includes two porcelain bottle sleeves for wrapping the top of the porcelain bottle, one side of each porcelain bottle sleeve is provided with an outer wire sleeve for wrapping the wire, and the other side of each porcelain bottle sleeve is provided with a telescopic wire sleeve that is butt-jointed with each other and symmetrically arranged with the outer wire 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 telescopic wire sleeve is provided at the outer wire sleeve. The lower side of the telescopic wire sleeve is provided with a slit which is connected with the opening of the lower end of the porcelain bottle sleeve, and the two sides of the slit are respectively provided with a butt joint edge which extends downward; the telescopic wire sleeve is composed of a wire outer sleeve and a wire inner sleeve, and the end of the wire outer sleeve is coaxially sleeved on the outer side 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 it is characterized in that a clamping plate which matches the shape of the butt joint edge is connected to each other through an elastomer on the opposite side of the two butt joint edges.

[0004] The disadvantages of this insulating sheath are: no clamping plate is provided in the slit of the telescopic wire sheath between the two porcelain bottle sheaths, so the clamping force on the power line here is small and the power line cannot be clamped; only a mounting plate is provided on each porcelain bottle sheath, and once a problem occurs in the installation (such as unbalanced installation resistance at both ends, one end of the insulating sheath cannot be installed), it is not easy to install it in place. Summary of the invention

[0005] The invention provides a double-porcelain-bottle hard insulating sheath for a utility pole with an auxiliary mounting plate and capable of being 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 for a utility pole with an auxiliary mounting plate and capable of being installed under power, comprising two porcelain bottle sheaths for wrapping the top of the porcelain bottle, an outer wire sheath for wrapping the wires is provided on one side of each porcelain bottle sheath, and a telescopic wire sheath butted against each other and symmetrically arranged with the outer wire sheath is provided on the other side of each porcelain bottle sheath; an opening corresponding to the upper part of the porcelain bottle is provided at the lower end of the porcelain bottle sheath, a slit penetrating with the opening at the lower end of the porcelain bottle sheath is provided at the lower sides of the outer wire sheath and the telescopic wire sheath, and a butt joint edge extending downward is provided on each side of the slit; the telescopic wire sheath is composed of an outer wire sheath and an inner wire sheath, the end of the outer wire sheath is coaxially sleeved on the outside of the end of the inner wire sheath, and can axially telescope relative to each other. Sliding; a butt joint edge identical to the butt joint edge is provided at the lower side of the wire outer sleeve and the wire inner sleeve, a mounting plate is provided on each porcelain bottle sleeve, and a mounting hole is provided on the mounting plate; 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 in an eight-shaped cross section; a clamping plate 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; the insulating sheath is made of a hard insulating material, and is characterized in that a middle clamping plate corresponding to the clamping plate is connected to each other on one side of the two butt joint edges of the wire inner sleeve through an elastic body; an auxiliary mounting plate is provided in the middle of the outer wire sleeve, and an auxiliary mounting hole corresponding to the mounting hole is provided on the auxiliary mounting plate.

[0007] The advantages of the present invention are as follows: a pair of middle clamping plates are added at the opening of the inner sleeve of the telescopic wire sleeve, which greatly increases the clamping force on the power line at this location, so that the overall installation of the sleeve is firm and the power line is prevented from falling out; two auxiliary mounting plates are added, the supporting position of the mounting rod can be changed or a double-head mounting rod can be used for installation, ensuring that it is installed in place at one time.
