The technical task is to increase the reliability of a device to prevent birds from landing on buildings. The device contains a monolithic U-shaped metal clamp, the first lip of which equipped with a fastening element, outside the first lip, with the help of a guide bolt and a guide hole, a polymer sleeve is installed with holes in which the rods are mounted, azuyuschie beam. The guide hole for the guide bolt can be made on the second lip or on the transitional part connecting the lips of the clamp. The holes in which the rods are mounted form rows with different angles of inclination relative to the guide bolt. The rods are made of polymer, with an influx at the ends. In addition, the rods can be made composite, for example, from a metal core equipped with a polymer braid, with an influx at the ends.

Description

The utility model relates to devices for scaring birds that prevent birds from landing on structures, including the towers of overhead power lines.

Known bird protection device of the anti-interference type (RU160993 U1), selected as a prototype, containing a clamp, a bunch of rods, a threaded guide bolt, a plastic sleeve, rods with caps at the ends are fixed in the holes of the sleeve, and the guide bolt is installed in the central hole of the plastic sleeve and fastened to the clamp, while the clamp consists of two corners and one Z-shaped corner, fixing bolts.

Its disadvantage is the low reliability of the composite clamp. Under the influence of precipitation, wind, the joints of its corners become loose, which can lead to a fall of the device and an accident on the power line.

The technical result of the utility model is to increase the reliability of the device to prevent birds from landing on structures.

The technical result is achieved in a device for preventing the landing of birds on structures (hereinafter referred to as the device) containing a monolithic U-shaped metal clamp, the first lip of which is equipped with a fastener. On the clamp, outside the first lip, with the help of a guide bolt and a guide hole, a polymer sleeve is installed with holes in which the rods forming the bundle are installed. The guide hole for the guide bolt can be made on the second lip or on the transitional part connecting the lips of the clamp. The holes in which the rods are mounted form rows with different angles of inclination relative to the guide bolt. The rods are made of polymer, with an influx at the ends. In addition, the rods can be made composite, for example, from a metal core equipped with a polymer braid, with an influx (broadening) at the ends.

The utility model is illustrated by the drawings:

figure 1 - a device for preventing the landing of birds on structures (shown section of a polymer sleeve);

figure 2 - the implementation of the guide holes on the transitional part of the clamp;

figure 3 - the implementation of the guide hole on the lip of the clamp.

A device for preventing the landing of birds on the structure contains a monolithic U-shaped metal clamp 1, made by stamping or bending a solid metal billet. The first and second lips 2, 3 of the clamp 1 form two flat surfaces facing each other, over most of the area. Due to this, it is possible to install clamp 1 on the elements of power transmission line supports (beams, traverses), wires, which are extended parts. The transition part 4 (indicated by dashed lines in FIG. 2, 3) may have an uneven radius of curvature, that is, a U-shape here is understood to include, inter alia, a U-shape and a V-shape, ensuring the presence of predominantly parallel internal surfaces on the ends of the lips 2, 3 and the curved transitional part 4.

The first lip 2 is equipped with a fastening element 5, made in the form of a bolt with a nut, with the help of which the clamp 1 is mounted, for example, on a power transmission line support.

On the clamp 1, outside the first lip 2, with the help of a guide bolt 6, a polymer sleeve 7 with holes 8 is installed, in which the rods 9 forming a bundle are installed. The guide hole 10 with a thread in the clamp 1, for the guide bolt 6, can be made blind or through and is located on the second lip 3 or on the transitional part 4 connecting the lips of the clamp. Depending on the location and angle of the guide hole 10, the orientation of the beam of the rods 9 relative to the lips 2, 3 changes. This choice is made depending on the design of the power line support or other structure. In the clamp 1, several threaded guide holes 10 can be made.

The holes 8 in which the rods 9 are mounted form rows with different angles of inclination relative to the guide bolt 6. Thus, when the rods 9 are installed in different rows of holes 8, a beam is formed.

The rods 9 are made of polymer, with an influx (broadening, for example, in the form of a drop or ball) at the ends, to reduce the risk of injury to birds. In addition, the rods can be made composite, for example, from a metal core equipped with a polymer braid, also with an influx. The rods 9 are fixed in the holes 8 by pouring with a hardening substance (glue, resin, etc.) or by selecting the diameters and elasticities of the materials of the polymer sleeve 7 and the rod 9 so that the installation is made with effort.

Thus, due to the monolithic construction of the clamp 7 and the fastening of the polymer sleeve 7 directly to the lip 3 of the clamp 1 or to the transition part 4, simplicity of manufacture and reliability of the device are ensured, it is possible to set the orientation of the beam of the rods 9 relative to the clamp 1 by making a guide hole 10 on different parts of the clamp one.
