Description

The utility model relates to the field of electric power engineering, namely, to a device for preventing birds from landing and nesting on traverses of overhead power transmission lines. The device can be used to protect strings of insulators from contamination by the waste products of birds, as well as to scare away and protect the birds themselves from electric shock on overhead power lines. The device prevents birds from touching live elements and birds nesting on overhead power lines.

From the prior art there is known an anti-perching device for preventing birds from landing on poles of power transmission lines, comprising a fastening element in the form of a clamp with a bolt for fastening to the corner of the power line traverse. At the same time, the deterrent element is made in the form of a pointed cone-shaped cap formed by a concave hyperbolic curve or any other similar curve, the cap length will be 300-500 mm with a base diameter of 300-500 mm, and it is made of UV-resistant plastic with electrical insulating properties ... The cap has an internal channel in the center of the base, through which it can be moved along the axis of the rod or tube connected to the clamp, followed by fixation of the cap (RF patent 156367 U1, published on November 10, 2015, IPC: H02G 7/00).

It is also known a device for excluding the possibility of landing and nesting of birds on the traverses of the supports of overhead power lines, consisting of an anti-attachment element and an attachment unit. The anti-adherent element is made in the form of a lid made of a polymer material with oval curves in its lower part or from a lid, to the oval-shaped curves of which an additional bottom is attached, while the outer surface of the lid is partially covered with shading that stands out against the background of the lid surface (RF patent 2622884 C1 , published 21.06.2017; IPC: H02G 7/00).

As the closest analogue to the claimed technical solution, an anti-attachment device can be considered designed to protect garlands of insulators of overhead power lines with a voltage of 6-1150 kV, as well as to protect birds from the negative effects of the overhead power lines themselves (RF patent 2673456 C1, published on November 27, 2018 , IPC: Н01В 1/02). This device is installed on a traverse or on other elements of the support, or on a string of insulators, or in the immediate vicinity of the string of insulators above it and consists of at least one anti-attachment element and a fastening unit. The anti-adherent element is made in the form of a thin-walled shell. The casing is made of polymer material and can consist of several parts, fastened with latches.

The disadvantage of these analogs is their rather low efficiency due to their poor visibility (noticeability) and insufficient deterrent properties for birds. Also, some of the analogues may not be sufficiently resistant to wind loads.

The objective of the claimed utility model is to develop a device for preventing birds from landing and nesting on traverses of overhead power transmission lines, demonstrating improved efficiency and structural strength due to increased visibility and bird-repelling effect. In addition, the utility model is aimed at expanding the arsenal of means for protecting overhead power transmission towers from birds and their waste products.

The technical result consists in creating a device with improved efficiency in relation to scaring away birds and protecting garlands of insulators from contamination with their waste products, as well as protecting the birds themselves from electric shock on overhead power lines.

The specified technical result is achieved in that the claimed device for preventing the landing and nesting of birds on the traverses of the supports of overhead power lines contains an anti-attachment element and an attachment unit, while the anti-attachment element is made in the form of a polyhedral cone with a through hole having at least five flat faces in the form an isosceles triangle, connected by common edges, and a base.

FIG. 2 shows a general view of the device fixed on the support for preventing the landing and nesting of birds on the traverses of overhead power transmission lines in accordance with one of the embodiments.

The claimed device for preventing the landing and nesting of birds on the traverses of overhead power transmission lines (see Fig. 1) prevents birds from landing on the traverse of the support in the area of the insulator string, and thus does not allow the insulators to be contaminated.

Structurally, the device for preventing the landing and nesting of birds on the traverses of the overhead power transmission line supports contains an anti-attachment element and a fastening unit. The anti-adherent element is a cone with several flat faces 3 (polyhedral cone) made of a light dielectric material, for example, plastic, and a base. The number of faces 3 of the cone can be different, equal to 5 or more (see Fig. 1-2). The planar faces have the shape of an isosceles triangle and are connected by their lateral sides by means of edges 2, each of which is common to two adjacent (adjacent) faces. The base of the anti-adherent element covers it from below and can be made of the same material as the cone, preferably has the form of a flat plate with radially oriented stiffeners or the form of a cone. In the second case, the base can be made at an angle of no more than 25 ° relative to the horizontal plane towards the cone of the anti-adherent element. The design of the anti-adherent element is collapsible (detachable), that is, the base is removable, due to which ease of assembly and maintenance of the device is achieved.

A through hole is made inside the anti-adherent element along its axis, through which the rod 5 of the attachment unit passes. The rod 5 of the attachment point can be made of metal or other material (including polymer), providing sufficient strength and reliability of the structure. In addition to the rod 5, the attachment unit may contain a universal U-shaped bracket 4 for mounting the device on a horizontal or vertical surface.

In one of the preferred embodiments, an anti-attachment spike 1, which can be made of metal or polymer material, can be installed at the top of the anti-attachment element. In a particular case, the anti-attachment spike can be a continuation of the rod 5 of the attachment point. The anti-attachment spike prevents birds from landing on top of the anti-attachment element, thus enhancing the function of the device.

As it was unexpectedly discovered by the authors of the claimed device, the implementation of the upper part of the anti-perishable element in the form of a polyhedral cone significantly increases the visibility (visibility) of the device for birds and enhances the deterrent effect. This is achieved due to uneven (discrete) reflection of light from the anti-primer element.

In addition to the design of the device, the authors also found that the application of additional reflective or other bird-repelling coating on the edges of the anti-attachment element may be of great importance for enhancing its functions and achieving the technical result. Such a coating can only be applied to some of the edges, for example, through one. The use of a special paint or coating can significantly affect the perception of the anti-adherent element by birds, and as a result, significantly increase the visibility and deterrent properties of the device.

The claimed device optically scares away birds and physically prevents them from landing in the protected area of the support without injuring the birds.
