Description

Technical field

The utility model relates to devices that protect birds from electric shock on power lines (LEP), and can be used to prevent electrical contact of the bird with a supporting clip, which fixes the LEP wire on the insulating suspension of the intermediate support, and can also serve as additional protection of TL elements from exposure to waste products of birds.

The level of technology

Known selected as a prototype bird protection cover for supporting clamps, containing two trough-shaped sash of insulating material, each of which has an upper, side half-pipe and made with the possibility of covering the clamps installed on the power lines supporting clamp with adjacent insulating suspension element and sections of the supported wire [ RU 180082]

In the prototype, trough-shaped shutters are made of rigid plastic (polymer insulating material) and connected using two detachable axial hinges.

The disadvantage of the prototype - the complexity and complexity of manufacturing the casing and its installation on power lines. The fabrication of the casing includes the separate molding of the two flaps and the assembly operations for connecting the flaps using two axial hinges. When mounting the casing to power transmission lines, the supporting clip together with the insulating suspension element adjacent to the clip and parts of the supported wire is first positioned in one of the leaflets connected by two hinges, and then, holding this shutter and turning the second shutter around the two hinges, fix the cover to the clamp in the closed state .

The essence of the utility model

The technical result of the utility model is to simplify the manufacture of the casing and its installation on power lines with ensuring reliable fixation of the casing on the supporting clamp and the adjacent elements of power lines.

The subject of the utility model is a bird protection cover for supporting clamps, containing two trough-shaped shutters made of electrically insulating material, which have upper, side half-sleeves and are designed to cover the supporting clip with adjacent insulating suspension element and parts of a supported power line wire, characterized in that the cover formed as a single silicone part from two trough-shaped valves, elastically conjugated with the possibility of opening and subsequent sm Clicking along the contour that encloses the contour of the supporting clamp, while along the contour of the closure, the trough-shaped sashes, including their half-hinges, are provided with fringing in which there are holes for the fixing means.

This allows to obtain the specified technical result.

The development of the utility model is that:

- through drainage holes are made in the casing;

- the outer surface of the casing is made with the possibility of visual scaring of birds;

- sash coupled with the possibility of coverage of the clip below;

- the flaps are associated with the possibility of covering the clamp on the side;

- half-hinges of the valves are made with the possibility of docking with bird protection protectors of power lines.

Implementation of the utility model in view of its development

The figure shows a General view of the inventive casing. The casing has two trough-shaped flaps 1 and 2, conjugated along line 3.

The casing is made in the form of a single silicone part with the possibility of opening and subsequent closing of the valves 1 and 2.

The flaps 1 and 2 of the casing are elastically connected to each other along line 3 so that when the flaps open, the casing can be freely or with little effort put on a supporting clip, and after closing the flaps 1 and 2, it covers the clamp together with the metal element of the insulating suspension and plots supported by power lines. The possibility of elastic conjugation of the valves is provided by both the properties of silicone and the choice of the thickness of the casing (2.5 ÷ 5.0 mm).

Sash 1 and 2 can be paired to cover a supporting clamp mounted on a power line from below or from the side. In the first case, line 3 is located on the bottom, and in the second case, on the side of the supporting clamp. In both cases, the contour of the closing of the trough-shaped shutters covers the contour of the supporting clamp so that the shutters adjoin the clamp tightly or with a slight play.

To cover the sections of the power line wire adjacent to the clamp, each casing flap is formed with two side half pipes 4, and to cover the element of the insulating suspension adjacent to the clip, it has one upper half half 5. At the closing of the cusps, the half pipes 4 form two side sockets covering the areas adjacent to the clip , and the half-socket 5 - one upper bell, covering the element of the insulating suspension adjoining the clamp, on which the supporting clip is fixed. The upper bell (half-socket 5) may have cylindrical and conical sections. Side sockets (half-sockets 4) can be cylindrical or conical.

The pipes formed by the half-plugs 4 and 5 prevent the bird from making electrical contact with the areas of the supported wire adjacent to the clamp and with the lower metal element of the insulating suspension. Side-mounted half-plugs can be mechanically coupled to the bird protection treads of the power lines, for example, using a tongue-and-groove connection (connection protrusion-groove) or coaxial holes for fixing means.

The flaps 1 and 2, including their half-sleeves 4 and 5, are provided along the closing contour with the fringes 6 and 7, respectively, which adjoin each other when the flaps 1 and 2 are closed. In the edging biw the edging 7 is made opposite each other holes 8 for fixing means (for example, plastic rivets, clips, clamps), which in the closed state of the valves 1 and 2 fix adjacent edging 6 and 7.

In the casing, for example, through line 3, through drainage holes 9 can be made for draining moisture and dirt.

To visually frighten the birds away, the casing may have a bright color; a pattern that frightens the birds may be applied to the outer surfaces of the valves.

The proposed casing can be made of silicone (silicone electrical insulating rubber) by the known technology of direct (compression) pressing, described, for example, in the monograph Yarushina S.G. Technological processes in engineering. Moscow, 2017.

The mold for the manufacture of the inventive casing consists of two half-molds that form the outer surface of the casing (i.e., the outer surfaces of the flaps 1, 2 with edges 6, 7 and the half-holders 4, 5) and the liner that forms the hollow of the casing and the inner surfaces of the flaps 1 and 2

Plastic raw silicone is placed in one of the half-molds, then an insert is placed, on top of it is still raw silicone and the second half-form. The silicone mold thus filled is squeezed with a press (the remaining material is squeezed into the technological grooves in the molds) and withstands the required time at a certain heating temperature. After that, the mold is disassembled, and the formed casing is in a half-closed form worn on the liner. At the same time between the edges 6 and 7 there is a small gap formed by the same liner. Next, the formed casing is removed from the liner, parts of the mold are cleaned and prepared for the manufacture of the next casing.

The installation of the casing on the supporting clamp power lines perform as follows. The casing in the form of a single silicone part with flaps 1 and 2, elastically conjugated along line 3, is worn on the supporting clip and the elements of the power transmission line adjacent to it from the bottom or side. After that, the valves 1 and 2 are closed to fit the edges 6 and 7 to each other. In this case, the supporting clamp is fixed in the cavity between the trough-shaped shutters 1 and 2, made in accordance with the shape of the supporting clamp, and the element of the insulating suspension and sections of the power transmission line adjacent to the clamp - in the corresponding sockets.

Then, coaxial holes 8 of adjacent fringes 6 and 7 are inserted into the means of fixation, for example, plastic rivets, clips, clamps.

As can be seen from the above, the claimed solution simplifies the manufacture and installation of the casing, as well as ensures reliable fixation of the casing on the supporting clamp covered by it together with the adjacent elements of the power transmission line.

This technical result is ensured by the fact that the casing is formed as a single silicone part from two trough-shaped shutters 1 and 2, elastically conjugated with the possibility of opening and subsequent closing along the contour enclosing the contour of the supporting clip, at the same time along the closing contour of the shutter 1 and 2, including their semi-sockets 4 and 5 are equipped with edging 6 and 7 with openings 8 for fixing means.
