Description

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

Known bird-protective device anti-additive type (RU160993 U1), selected as a prototype, containing a clamp, a bundle of rods, a threaded guide bolt, a plastic sleeve, in the holes of the sleeve fixed rods with caps at the ends, and a guide bolt mounted in the center hole of the plastic sleeve and fastened to 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, connections of its corners become loose, which can lead to a fall of the device and an accident on the power line. A device for preventing birds from landing on pylons of overhead power lines (RU2393603) is known, consisting of a bundle of rods pressed into a stepped rod, on the one hand having an opening for a bundle of rods, and on the other hand, made with a threaded part of a smaller diameter fixed on the support crosshead . A disadvantage of the known device is the inability to change the angle of inclination of the stepped rod depending on the operating conditions, on the location of the supporting surfaces on which the device is installed.

A device to prevent birds from landing on buildings (RU179789, selected as a prototype) contains a monolithic U-shaped metal clamp, the first lip of which is provided with a fastening element, outside the first lip, with a guide bolt and guide hole, a polymer sleeve with holes is installed, in which are installed the rods forming a bunch. 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. Polymer bushing is usually used with polymer rods, glue is used when installing rods. The use of a polymer sleeve with separate holes in which rods are installed, mounted on a metal guide bolt is not always permissible, when increased strength of connection with the guide bolt is required or it is necessary to exclude detaching rods from the polymer sleeve or a combination of metal and non-metal parts is unacceptable by technological or operational, or weather conditions on power lines. A device with a polymer sleeve, with the installation of rods in separate holes is complex and low-tech to manufacture.

The technical task of the utility model is to expand the arsenal of devices to prevent birds from landing on buildings, the rods of which can be repeatedly and reliably installed at different angles relative to the support.

The technical result is achieved in a device to prevent birds from landing on structures containing a monolithic U-shaped metal clamp provided with at least two guide holes located on parts of the clamp turned relative to each other, a fastening element, a guide bolt with a metal tube at the end, in which the metal rods forming a bunch are pressed. The guide holes are threaded. The guide holes are located on different lips clamp. One guide hole is located on the lip of the clamp, the second guide hole is located on the transitional part.

The utility model is illustrated by drawings: FIG. 1 is a device for preventing birds from landing on structures; figure 2 - the end of the rod; figure 3-4 options for installing the device.

The device for preventing birds from landing on structures contains a monolithic U-shaped metal clamp 1, made by stamping or folding a solid metal blank.

The first and second lips 2, 3 clamps 1 form two, facing each other, over most of the area, flat surfaces. Due to this, it is possible to install clamp 1 on the elements of power transmission line supports (beams, cross-beams), wires, which are extended parts. Transition part 4 (in the figures indicated by dotted lines) may have an uneven radius of curvature, that is, the U-shape here is also understood to include the U-shape and V-shape, which ensures the presence of mostly parallel internal surfaces at the ends of the lips 2, 3 and the curved transition part 4.

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

The clamp 1 is provided with at least two guide holes 6, 7 located on the parts of the clamp 1 turned relative to each other, for example: on the second lip 3 and on the transition part 4. The guide holes 6, 7 can also be located on different lips clamp.

The guide holes 6, 7 are threaded for installation in one of them of the guide bolt 8 with a metal tube 9 at the end, in which metal rods 10 are formed, forming a bundle. Depending on the location and angle of the guide holes 6, 7, the orientation of the bundle of rods 10 changes relative to the lips 2, 3. This choice is made depending on the design of the pylon or other structure. The rods 10 are made of metal, curved at the ends (position "A" in Fig. 1, 2), to reduce the risk of injury to birds. The orientation of the bundle of metal rods 10 relative to the clamp 1, in addition, can be changed by the bend of the rods 10.

Metal rods installed beam in the metal tube 9, it is possible to unbend and bend many times in the right direction, without destroying the material of the rods at the bend, as is the case with their separate installation. In addition, changing the angle relative to the support (the direction of the beam of metal rods 10) can be made by turning the guide bolt 8 in the threaded hole. Due to the possibility of multiple installation of metal rods in different directions relative to the support, increases the service life of the device.

Pressing the metal rods 10 in the metal tube 9 can be done with the heating of the metal tube 9, a laser beam, a torch flame or plasma can be used.
