Description

The invention relates to the field of electric power industry, in particular to devices for repelling birds from landing and nesting them on the cross-arms of supports of overhead power transmission lines, which helps to prevent the death of birds from electric shock, and also provides protection and at the same time conditions for reliable operation of overhead power transmission lines of various voltage classes.

A device is known for preventing birds from landing on the supports of overhead power lines, containing repellent elements, characterized in that the repellent 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 mounting unit of the supporting garlands of insulators, and the other the end is braided in the form of a whisk, and the device is mounted on a traverse on the attachment point of the supporting insulator strings directly above the insulator strings [1].

This known device is ineffective from the point of view of optimal protection of medium and large birds, since such birds, when trying to sit on the device or make a nest on it, can easily injure themselves on the sharp ends of the segments of lightning protection cables, due to their size (wide wingspan, large beak and claws, swaying of cable segments due to the large weight of birds, etc.).

The closest technical solution in relation to the proposed one is a device to scare away birds from landing and nesting them on the traverses of the supports of overhead power transmission lines, made at least in the form of one module having the ability to connect with other same modules to provide a protected zone to the required length , each of the modules consists of a detachable or one-piece base and rods, the sides of the base are made with an element for connecting the bases to each other, while at least two slots are made in the aforementioned base for attaching it to the traverse of the line support [2].

This bird repellent device cannot be considered universal enough from the point of view of effective protection of birds of numerous species and breeds from electric shock, due to the choice of the optimal number of rods in the module, their limited cross-sectional shape, the location of the rods in one spatial plane, and the manufacture of the end part of the rods, albeit of an oval smooth shape, but still allowing the possibility of injury to some species of birds (eagles, hawks, etc.) if accidentally touched or attempted to land on such rods.

The applicant set a specific goal, namely, to create a more effective and universal in terms of protection against electric shock overhead power transmission lines of birds of various species compared to a device for repelling birds of a similar purpose in the patent prototype No. 2660467 (as shown by the practice of using this device , it turned out to be ineffective and not universal for some large and especially valuable species of birds, especially birds of prey). This positive technical result was achieved due to the combination of essential design features of the claimed device, given in the following utility model formula: “a device to scare away birds from landing and nesting them on the traverses of the supports of overhead power lines made in at least one module having the ability to connect with other modules to provide a protected zone to the required length, while the module consists of a detachable or one-piece base and rods, the sides of the base are made with an element for connecting the bases to each other, while at least two slots are made in the aforementioned base for fastening it to the traverse of the line support; rods, selected in an amount from two to eight pieces, are made of the same shape and / or the shape of the rods is different from each other, at the base of the rods are made with a cross section of a cross-shaped, polyhedral, round, rectangular or oval shape and are located in the same plane or different planes at the same time, at least one rod is made with an end shape, eliminating the possibility of injury to the bird in case of accidental contact or attempt to land on this rod; it is fastened with at least one wire or tape, or by means of a polymer coupler with a lock, tightened in the slots of the module, or simultaneously by several of the above methods; or it is attached using at least one clamp; at least one rod has a terminal assembly for connecting to a rod extension. "

The essence of the utility model is illustrated by drawings, where in FIG. 1 is a perspective view of a bird repellent apparatus made in accordance with the present invention, front, top, side, and axonometric views.

The inventive device to scare away birds from landing and nesting them on the traverse of the supports of overhead power lines is made in the form of one module having the ability to connect with other modules to provide a protected zone to the required length. The module consists of a detachable or one-piece base 1 and rods 2. The optimal number of rods in one module is selected from two to eight pieces. An element (for example, a groove 3 and a spike 4, respectively) is made in the sides of the base 1 of the module to connect the various modules to each other. At the base 1 of each module, slots 5 are also provided for attaching the modules to the crosshead of the overhead power line support (not shown).

The rods 2 are made of the same shape and / or the shape of the rods is different from each other. At its base 1, rods 2 can be made with a cross-section of a cross-shaped, multifaceted, round, rectangular or oval shape. The rods 2 are located in the same plane or different planes. End forms 6 of rods 2 make it possible to exclude the possibility of injury to birds of various species in case of accidental contact or attempt to land on rods 3.

The device can be mounted on the traverse of the support of the overhead power line by means of a wire, tape, a polymer coupler with a lock, tightened in the slots 5 of the modules, or by, for example, one clamp 7.

One of the rods 2 may have a final node 6, intended for connection with the extension of the rod 2.

The invention works as follows.

The modules, as a rule, are delivered for installation on the overhead power line in the assembled state, that is, rods 2 are fixed in the base 1 of the modules. Then, if several pieces are required of the modules, they are connected to each other in a simple way, namely, the spike 4 of one module is inserted into the groove 2 of the other module, respectively, and so on, one after the other in series. After that, one module or several modules connected together are fixed on the traverse of the support of the overhead power line using one of the above-mentioned standard methods of securing devices of this type.

The proposed device to scare away birds from landing and nesting them on the traverse of the supports of overhead power transmission lines, as shown by the practice of its industrial use, in comparison with a device for repelling birds of a similar purpose according to the patent prototype No. 2660467, was more effective and more universal in terms of protection against damage electric shock overhead power lines of birds of various species, in particular large birds. This positive technical result is ensured primarily by the selection of the optimal number of rods in the module, the manufacture of rods of the same shape and / or shape different from each other, a wide range of shapes of the rods in cross section, the location of the rods in space not only in one plane, but also in different spatial planes, in addition, the end parts of the rods exclude injury to birds in case of accidental contact or attempted landing and are equipped with devices that allow to increase or decrease their length.
