Description

The invention relates to the electric power industry, and in particular to devices for eliminating the possibility of landing and nesting birds on the cross-arms of the supports of overhead power lines, as well as for protecting suspension insulators from contamination by vital products of birds and birds themselves from electric shock on 35 kV - 750 kV overhead lines.

A device is known for preventing birds from landing on the supports of overhead power lines, containing repelling elements, characterized in that the repelling elements are made in the form of a segment of a lightning protection cable, one end of which is pressed into the sleeve, the internal threaded part of which corresponds to the thread of the attachment point of the supporting garlands of insulators, and the other the end is braided in the form of a corolla, and the device is mounted on a traverse on the mounting unit of the supporting insulator strings directly above the garland of lyatorov [1].

Birds, trying to sit on this device, made in the form of a piece of a lightning protection cable, and make a nest for themselves, are very likely to get injured on the sharp ends of the elastic wires of the lightning cable and / or severely damage the wings when spreading. Attempts to land on devices of this design will always be undertaken by birds and, therefore, they are very dangerous for them, and the operation of such devices is prohibited by ornithologists.

It is also known a device for preventing birds from landing on the supports of overhead power lines, containing deterrent elements made in the form of a bundle of elastic rods rigidly mounted on the traverse of the supports, characterized in that it is equipped with two bushings, pieces of a flexible cable and a stepped rod, while the elastic rods made of polymeric materials or in the form of metal wires crimped from one end, and from the other stretched out by a fan and made with a bend relative to the longitudinal axes of metal wires ok, in the step rod, on one side, a hole is made for the pressed end of the metal wires, and on the side of the smaller diameter, the rod is made with a threaded part for fixing the support on the traverse, the bushings are rigidly attached perpendicular to the step rod, and the segments of the flexible cable are fixed in the bushings arranged symmetrically relative to the vertical axis of the stepped rod along the yoke in the area between the chains of insulator strings [2].

This technical solution, in addition to being extremely complicated in design, also cannot be recommended for use on overhead power lines because of the main drawback associated with the desire of birds to sit on it and a high degree of injury and even death.

The applicant set a specific goal - to develop a device to exclude the possibility of landing birds on the cross-arms of the supports of overhead power lines, so that the birds would not try to sit on it and arrange nests on it, due to the design features of the device and the presence of elements that frighten off birds, in addition quite simple in design and installation, reliable in operation. This positive technical result was achieved due to the combination of essential design features of the claimed device to exclude the possibility of landing and nesting birds on the cross-arms of the overhead power transmission towers shown in the following claims: the device to exclude the possibility of landing and nesting birds on the cross-arms of the electric power transmission poles consists of lids with oval curvatures in its lower part or from a lid to the curves of which an additional component is attached the bottom and the attachment point, while the cover is made cone-shaped or spherical or ellipsoid or of another geometric shape and made of smooth polymer material that excludes the possibility of injury to birds by accidental contact or attempted landing, and contrasting patterns with images of predatory eyes are applied to the outer surface of the cover beasts and dashed lines making the device more visible to birds and enhancing its protective effect; the additional bottom, docked to the bottom of the cover, is made in the form of a rim stretched on its inner side by stiffeners coinciding in the direction with the direction of the radii drawn from the point that is the center of the cover; the attachment site consists of a rod, on one end of which a lid is mounted, and a U-shaped clamp with bolts is fixed on the other, which secures the device to the traverse shelf in the entire range of applied sections of its corner; as a smooth polymer cover material, weatherproof plastic of orange or gray color is used, which provides resistance to ultraviolet radiation with a guarantee of 40 years and precipitation, the absence of deformations and operability in the temperature range from -60 ° C to + 50 ° C; its apparent distance is 500 meters.

The invention is illustrated by drawings, where in FIG. 1 is a schematic model of a device for eliminating the possibility of landing and nesting birds on the traverse of the supports of overhead power lines made in accordance with the present invention, an embodiment of the device in the form of a cone; in FIG. 2 is the same as in FIG. 1 is a drawing of a conical cap; in FIG. 3 is the same as in FIG. 1, a drawing of an additional bottom at the bottom of a conical cover; in FIG. 4 is a model of a device made in the design in which it is specifically supplied on line.

The inventive device to exclude the possibility of landing and nesting birds on the traverse of the supports of overhead power lines consists of a cover 1 and a mount. The lid 1 can be made in the form of a cone (Fig. 1), a sphere, an ellipse, or another geometric shape and has a regular oval shape in its lower part of the curve 2. It is made of a smooth polymer material, eliminating the possibility of injury to birds in case of accidental contact or attempted landing. On the outer surface of the lid 1 are applied contrasting patterns 3 with images of the eyes of a predatory beast and dashed lines 4, making the device more visible to birds and enhancing its protective effect.

Alternatively, an additional bottom can be attached to the bottom of the lid 1, made in the form of a rim 5 docked to it, stretched on its inner side by stiffeners 6, coinciding in direction with the direction of the radii drawn from point 7, which is the center of the lid 1.

The attachment site of the device consists of a rod 8, on which one cover 1 is mounted, and a U-shaped clamp 9 with bolts 10 is fixed on the other, which secures the device to the traverse shelf (not shown) in the entire range of applied sections of its corner.

As the polymer smooth material of the cover 1, weather-resistant plastic of orange or gray color is used, which provides resistance to ultraviolet radiation with a guarantee of 40 years and precipitation, the absence of deformation and operability in the temperature range from -60 ° C to + 50 ° C, fire safety.

The distance from which this device is visible to birds is 500 meters, the dimensions of cover 1 are: diameter 600 mm, height 250 mm, thickness 3 mm.

The invention works as follows:

On the basis of Decree of the Government of the Russian Federation of August 13, 1996 No. 997 p. 34 “Power lines, poles and insulators should be equipped with special bird protection devices, including preventing birds from nesting in places that allow birds to touch current-carrying wires. It is forbidden to use uninsulated metal structures as special bird protection devices. ”

The authors have developed a new special device made of polymer material to protect overhead power lines from birds, which allows implementing the environmental policy of all interested parties in the field of ornithological safety of power supply. The device is installed on the traverse of the supports of the overhead power line above the place of attachment of the garlands of insulators and prevents the bird from landing on the traverse in the zone of its protection. In addition, contrasting patterns with images of the eyes of a predatory beast are applied to the product, which makes the device more visible to birds, and enhances the protective effect of the device. The proposed device has an important advantage over other anti-slip devices (such as "hedgehog", "panicle", etc.), because, unlike them, it can not serve as the basis for the construction of nests. The inventive device is an exclusive product and has no close analogues in the Russian market, while in its manufacture all the necessary regulatory documents are observed.

The main advantages of this device:

- safety for birds - made of a polymeric material with a smooth surface; conical, spherical or other sloping geometric figure with special oval-shaped roundings, which does not allow the bird to fix on the device and begin to twist the nest;

- universality of mounting on traverses - a “clamp” type mounting unit provides mounting of the device to the traverse shelf in the entire range of angle sections used;

- made of weather-resistant material with a long warranty period, withstanding wind and ice loads in accordance with the requirements of the PUE;

- does not require additional maintenance.
