AVIFAUNA PROTECTOR IN HIGH VOLTAGE ELECTRICAL TOWERS

D E S C R I P C I Ó N

OBJECT OF THE INVENTION

The present invention relates to a birdlife protector in high voltage electrical towers, which has been specially designed to prevent the electrocution of birds that could perch on high voltage posts in proximity to the cables carrying said posts.

BACKGROUND OF THE INVENTION

In the high-voltage lines, the corresponding cables are sufficiently separated from each other so that the larger birds, such as eagles, storks and others, cannot touch with their extended wings two wires of the line, since in that case The electrocution of the bird would occur, so that this separation is sufficient to precisely prevent the bird of the type referred to in turn from simultaneously touching two high voltage cables.

However, the same does not happen at the level of the posts, where electrocution can be carried out by simultaneously touching a single cable and a part of the metal structure of the tower, being in these places and in the circumstances referred to where death occurs of most birds of important species such as eagles and others.

Trying to obviate this problem, the applicant himself is the holder of the utility model ES 1071672 U, in which a protector for birdlife is described and claimed, which is constituted from a hardware that is fixed to the crosshead or any other place appropriate of the corresponding pole or tower through which the cables of the high-voltage line pass, hardware to which an insulator consisting of a bar of, for example, silicone or any other polymeric insulating material, with a notable length, even greater than even one meter from

such that this insulating element at its opposite end to that of the tower or pole, is coupled, through metallic elements, to the corresponding conductor cable.

The protector as a whole is complemented by an enveloping spiral of both the aforementioned metal elements and the insulator itself, preventing the bird from perching on the insulating bar, so that whether it is perched on the crosshead, for example, of the post or tower, as if perched on the conductor cable, the distance is sufficient so that there is no risk of the bird simultaneously touching the metal structure of the tower or pole with its wings and at the same time the conductor cable.

These types of devices have a problem with a double aspect:

On the one hand, the spiral is arranged by winding the metal elements to be insulated, without any type of fixation, so that its fixation is not as safe.

In parallel, the said spiral has a constant section throughout its length, of considerable diameter, which makes it possible to accumulate a large volume of snow that by its weight can make it move to said spiral, leaving the area to to protect.

DESCRIPTION OF THE INVENTION

The avifauna protector in high voltage electrical towers that has been recommended has been designed to solve the above-mentioned problem, based on a simple but highly effective solution, being provided precisely so that in case a bird is possessed in proximity to a tower of a high-voltage line, the electrocution of that one does not occur, since on the one hand the protector is provided so that in case the bird is placed on the conductor, it is sufficiently distanced from the tower to prevent it from touching this with the wing, and thereby avoid electrocution, or in the case of perching at a point closer to the tower, then an insulation is established between the metal fastening parts of the conductor cable and the tower itself.

More specifically, the device of the invention is intended to be implanted between the hardware that is fixed to the crosshead or any other appropriate place of the corresponding post or

tower through which the cables of the high-voltage line and the tie-down clip pass through which the high-voltage cable is held by the tower and redirected internally to the opposite end of said tower, disposing between both elements (hardware of fixing to the tower and clamp of tie of the cable of high tension, a bar or cane polymeric insulator, of certain length.

The device is materialized in a wrapping spiral of both the aforementioned metal elements and the insulator itself, preventing the bird from perching on the insulating bar, so that whether it is perched on the crosshead, for example, of the post or tower, as if it is perched on the conductor cable, the distance is sufficient so that there is no risk of the bird simultaneously touching the metal structure of the tower or pole with its wings and at the same time the conductor cable.

The spiral will preferably be obtained in fully insulating PVC, finishing at its ends in respective galvanized clamps through which the device will be fixed immovably and by screwing the fixing hardware to the tower and the fixing end of the insulator or polymeric rod to the clamping clip of the high voltage cable preventing the assembly from moving, as was the case with the utility model mentioned above.

At the same time, it has been foreseen that the spiral does not have a constant section, but that in its middle zone it incorporates a strangulation, that is to say a reduction in the diameter of its turns, in order to avoid the accumulation of snow on it.

DESCRIPTION OF THE DRAWINGS

To complement the description that will then be made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, and in particular of Figure 3, it can be seen how the protector of the invention is intended to be implanted between the hardware (1) as a fork, through which fixing to the corresponding crossbar of a pole or tower through which a high voltage line is passed, hardware to which one of the ends of an insulating bar (2) is attached as an insulating element, and with a considerable length, approximately one meter and even greater to that length, such that said insulating bar (2) is linked at its opposite end to metal fittings (3,4) arranged successively with each other and through which the anchoring, clamping and passage of the conductor cable ( 6) corresponding to the high voltage line by means of a clamp (5).

Although based on the insulating bar (2) a distance is established between the corresponding tower or pole of a metallic nature and the conductor cable (6) of the high-voltage line, however a bird, such as an eagle or other high wingspan, with its wings extended perched on the bar that constitutes the insulator or insulating bar (2), could simultaneously touch the conductor cable (6) and the metal structure of the tower to which the hardware is fixed (1) , where electrocution occurs in those cases.

Well, to avoid this problem, a spiral (7) of insulating material, preferably PVC, has been provided, which prevents the bird from perching on the insulating bar (2), and touching the structure (6) with its wings from the tower to which the hardware is fixed (1).

To this end, it is envisaged that the spiral will be shot at its ends in two radial couplings (8) whose free end has an inner bend (9) to which galvanized clamps (10) are linked, shown in detail in Figure 2, based on two 5 plates facing and adjustable by means of a nut (11), with two conformations (1212 ') for coupling adjusted to the inner bending (9) of the end of the spiral, as well as for its coupling, respectively, to the fittings ( 1) and the metal hardware (3), that is to the ends of the insulating bar (2), preventing the birds from perching on it.

As can be seen in figures 1 and 3, the spiral will have a number of turns of the order of eight, with a pitch between turns of the order of 140 millimeters and a diameter or section of the order of 12 millimeters, presenting its extreme turns a radius of the order of 200 millimeters, while in its central zone it will present a throttling (13) in which said diameter will be reduced to a magnitude of the order of 50 millimeters, which avoids the accumulation of snow in said central zone.
