Also visualization of wires ensures their detection by aircraft pilots and carriers of oversized cargo on roads, railways and water bodies.

Known signal ball marker according to the patent for the RF PM No. 215332 to prevent the presence of power lines (power lines), communications, crossing water barriers, as well as to scare away birds and prevent their collision with wires. The signal marker ball consists of upper and lower hemispheres with round drainage holes at the tops, connected to each other along the parting line using four pairs of fasteners and clamps in the form of grooves with lugs. Rubber inserts are inserted into the clamps in the form of grooves with four protrusions in four rows on the outside, which are fixed with bolts, nuts, washers. The upper and lower hemispheres contain annular and meridian grooves, the first - in the amount of two pieces and located parallel to each other. Hemispheres can be made of plastic or aluminum. The utility model has a complex structure and a complex technique for attaching to wires.

A bird protection device of the MM-02 type is known in the form of a ball for overhead power lines from 35 kV and above, for the balls a color scheme of white and red or combined balls is used, which implies their best visibility. The device is used in a limited range of wires from 6 mm to 8.4 mm. (https://www.lep-snab.ru/catalog/armatura-dlya-vl/zashchitnaya-armatura/signalnye-markery/ustroystva-zashchity-ptits-tipa-mm-02. Retrieved 20.02.2023).

Known signal ball-marker according to patent 2778136, used for marking wires and ground wires of overhead power lines. According to the invention, the signal marker ball contains two detachable hemispheres hinged to each other and provided with means of fastening on the wires in the form of clamping jaws with holes for passing the wire or ground wire of the overhead power line, formed when the hemispheres are closed together, while inside the marker ball are installed springs that pull the hemispheres together. At the ends of the springs there are hooks connected to the traction rod and stop. When capturing the ring and moving upwards, the hemispheres of the ball open, and the ball is removed from the wires. EFFECT: invention allows to reduce labor costs and provide the possibility of removing signal balls-markers without disconnecting the power transmission line. However, according to the invention, the specified ball-marker is used for wires of different sizes of a limited range, and a tight grip of the wires is provided by the selection of sponge material, which also limits the wide application of the product.

The technical task of the utility model is to propose a marker-type bird protection device that allows you to securely install the device for a wider range of wire sizes.

To solve the problem, it is stated:

A marker-type bird protection device in the form of a collapsible spherical structure equipped with means for attaching it to wires, characterized in that the device includes three identical modules made in contrasting color, which, when combined, form a spherical structure with drainage holes, the means for combining the modules are made in in the form of two spherical lugs of each module and with the possibility of overlapping adjacent spherical lugs of adjacent modules, the alignment of the modules with each other is ensured by means of a latch that includes in each module elastic protrusions with stops at the end on one lure and a reciprocal lug on the other lure, while the protrusions are made along the length with the possibility of adjustable relative position of the protrusions and the eyelet, along the axis of the device fastening on the wires, each module is equipped with two clamp elements with internal transverse ribs with a cross section in the form of a segment of a circle, while in the assembly of three modules all clamp elements are formed by freely compiling up to the stop on the wire two clamps of the clamping chuck type with cams with an axial channel with the possibility of covering the wire along the axis of the clamp, all elements of the module are made as a whole from dielectric weather-resistant plastic, while the means of fastening the device assembly to the wires is made in the form of clamps tightening the clamp on the wire.

Also, the clip elements of the marker-type bird protection device are provided on the outer surface with collars, which form a seat under the tightening collar when assembled.

In addition, the contrasting colors of the modules include white, black, red and orange; contrasting coloring of three identical modules can be made in different colors, the same color.

- in Fig. 1 - marker type bird protection device, assembled,

- in Fig. 2 - a separate device module,

- in Fig. 3 - view of the module from the side of the inner surface,

- in Fig. 4 is a top view of the complete bird protection device,

- in Fig. 5 - top view of the assembly with an increased wire diameter,

- in Fig. 6 is a general view of the assembled device with an enlarged

wire diameter,

- in Fig. 7 and 8 - examples of the use of an additional element (13), fixing the device on the wires.

The bird protection device (ROM) of the marker type, shown in finished assembled form in FIG. 1, contains three identical modules 1 (Fig. 2), which, when combined, form a spherical structure with drainage holes 2.

The assembly of three modules is carried out with the help of two lugs 3, as a continuation of the spherical surface of each module, by applying adjacent spherical lugs of adjacent modules 1.

The modules are aligned with each other by means of a latch, which in each module includes on one lug 3 elastic protrusions 4 with stops at the end 5 and a reciprocal lug 6 on the other lug. The protrusions along the length are made with the possibility of an adjustable relative position of the protrusions and the eye, Modules 1 are connected to each other only on wire 7 with a minimum specified wire diameter (for example, 8 mm, as in Fig. 4), and in other cases they do not close, as shown in Fig.6, while maintaining the imposition of the tides on part of the surface without opening due to the stops 5 protrusions that fix the extreme extended position of the modules 1 to each other. The possible movable connection of the modules with each other allows you to adapt during the installation of the modules to a wide range of wire diameters. Also stops 5 prevent accidental disconnection of the modules during installation.

To install and fix the ROM on the wires, each module is equipped with two clamp elements 8 with internal transverse ribs 9 with a cross section in the form of a segment of a circle. When assembled, when three modules are assembled together, all elements of the clamp 8 form, by freely compiling up to the stop on the wire, two clamps 10 with an axial channel with the possibility of covering the wire 7 along the axis of the clamp 10. Since three points on the plane always lie on the same circle, then and clamp 10, consisting of three clamp elements 8 (for example, according to the type of three jaws of a drilling chuck), provide equally reliable coverage of wire 7 at any relative position of modules 1: when fully shifted between each other on a wire with a minimum wire diameter to a maximum extended on the wire with the largest given diameter. As a result, when turning, when the PZD is displaced under the action of wind loads, the position of the wire along the PZU axis in contact at three points with the clamp elements 8 is always maintained. wires.

Also, three sectors of the spherical surface of the ROM make it possible to recognize, in any direction of observation, at least two sectors of the ROM, which improves the quality of recognition of the marker-type ROM. The choice of a contrasting color for the color of the modules also enhances this property both when choosing one contrasting color: either white, or black, or red, or orange, or any combination of them. The implementation of the ROM of three modules in a contrasting color greatly improves the visualization of the device directly to the birds.

The clamp assembly 10 is pulled together on the wire by means of the clamps 11, which prevents the relative displacement of the lugs 3 superimposed on each other and ensures the alignment of the wire along the ROM axis. The seat for the tightening clamp is formed by the collars 12 on the outer surface of the clamp 10. The clamps can be worm, tape or other type.

The termination force on the cable can be increased by installing additional clamps 13 directly on the wire on both sides of the ROM. Figures 7, 8 show an example of such an additional clamp, but any suitable one can be installed.

The proposed ROM with a spherical shape with a diameter of 220 to 250 mm can be installed on wires and cables of different diameters in the range from 8 to 35 mm.

All elements of module 1 are made as a whole of dielectric weather-resistant plastic, resistant to ultraviolet radiation; plastic models are made using plastic injection molding technology.
