The disadvantages of the known mount are the lack of versatility and does not allow secure fastening on bearing elements with different shapes and sizes.

The technical result of the claimed invention is to increase the degree of versatility of the device with increased reliability of mounting the bird protection device on the bearing elements of the consoles with various shapes and sizes of these bearing elements.

The problem is solved and the technical result is achieved by the fact that the attachment point of the bird protection device installed on the carrier element of the contact wire console is connected to the anti-attack element of the bird protection device and is fixed on the carrier element, while, according to the invention, the attachment point is made in the form of an angular profile with a horizontal and a vertical shelf connected to it, while the geometric longitudinal axis of the angular profile of the node is located along the carrier element, the anti-attack element is connected to the horizontal shelf, the plane of the vertical shelf intersects the ground surface, the lower side of the horizontal shelf and the side of the vertical shelf associated with it form contact surfaces with the outer surface of the profile of the supporting element of the contact wire console, and the vertical shelf of the angular profile is equipped with inclined shelves located along the lower side of the vertical shelf at an angle to each other, while the inner surfaces on sloped shelves form an additional surface of contact with the outer surface of the profile of the bearing element.

The technical result is also achieved by the fact that the anti-attachment element can be made in the form of a plate, a plate, the middle plane of which is located along the geometric longitudinal axis of the angular profile, while the plate is connected to the horizontal flange of the angular profile along the lower side of the contour, the plate is made, at least , one corner cutout, the top of which is facing the lower side of its contour, and the corner cutout is made with the formation of anti-seize element vertices in the areas of intersection of the sides of the corner cutout with the side moans of the plate contour.

The technical result is also achieved by the fact that the sides of the plate contour can be made with an inclination at an acute angle to its lower side.

The technical result is also achieved by the fact that the anti-attachment plate can be provided with stiffeners located between the lower side of the plate contour and each of the tops of the anti-attachment element.

The technical result is also achieved by the fact that vertical stiffening ribs can be made on one outer surface of the vertical flange of the angular profile.

The bird protection device (PZD) is installed on the elements of the console used to fix the position of the contact wire in the horizontal plane relative to the pantograph axis.

The console contains bearing elements installed on the support 1: the bracket 2 and the main retainer 3 associated with it, which is made in the form of a rod. Bracket 2 can be additionally connected to support 1 using an additional bearing element: rod 4 (horizontal rod). Depending on the execution scheme of the console (shown in Fig. 1-3), the insulator 5 can be installed between the support 1 and the bracket 2 (Fig. 1), between the bracket 2 and the main latch 3 (Fig. 2), between the support 1 and the main latch 3. An additional insulator 6 can be installed between the support 1 and the rod 4 (Fig. 1) or between the bracket 2 and the supporting cable of the contact wire (Fig. 2 and 3).

The bird protection device can be made, for example, in the form of an attachment point 7 and an anti-attachment element 8 associated with it. 8 is made in the form of a plate having contour sides, the median plane of which is located along the geometric longitudinal axis of the angular profile of the attachment 7 and the geometric longitudinal axis 10 of the bearing element and crosses the earth's surface (according to the definition given in the scientific and technical literature, the plane dividing the plate in half in thickness is called the median plane, and the line of intersection of the median plane with the side surface is called the contour of the plate).

The lower side 11 of the plate of the element 8, facing the ground, is connected to the attachment point 7. Its side sides 12, crossing the side 11, can be made with an inclination at an acute angle α to the side 11. An angular cutout 13 is made in the plate of the element 8, the top of which facing the lower side 11. The corner cutout 13 forms with the sides 12 in the areas of their intersection of the top 14, directed in the direction opposite to the surface of the earth. At the same time, the distance "A" between the peaks 13 is greater than the distance between the paws of large birds living in the region where the consoles are installed, and the angle β at each peak 13 should not exceed 30 degrees, which does not allow the bird to sit on the side inclined at such an acute angle. 12.

The described embodiment of the anti-attachment element 8 does not limit the choice of anti-attachment elements made according to a different design scheme, which can be fastened to the described attachment assembly 7, which provides the versatility of mounting the ROM on the bearing elements of the console.

The ROM is installed at the point of attachment of the carrier element to the insulator 5 and/or 6 from the side of the contact wire 15 (see Fig. 1-3).

The angular profile of the mount 7 has a vertical shelf 16, the plane of which intersects the surface of the earth, and a horizontal shelf 17 connected to its upper side. The lower side 11 of the plate of the element 8 is connected to the horizontal shelf 17 of the angular profile of the mount 7. Moreover, the terms "horizontal" and "vertical" are used to symbolize the shelves 16 and 17 and are not strictly binding to the ground surface. That is, their orientation allows some deviations from the vertical and horizontal.

The bearing element, on which the attachment point 7 PZU is fixed, can be made of a profile with different cross sections and with different orientation of the profile in space. So, the bearing element can be made in the form of a rectangular or angular profile (see Fig. 7-12), one of the sides of which is oriented approximately parallel to the ground surface. When using the specified profiles of the supporting elements, the surface of the horizontal 17 and vertical 16 shelves of the angular profile of the attachment 7 form the contact surface with the outer surface of the profile of the supporting element of the console of the contact wire. That is, the surfaces of the shelves 16 and 17 are associated with the outer surfaces of the angular or rectangular profile. Moreover, the distance from the longitudinal edge (in the transverse plane) of the horizontal shelf 17 to the plane of the plate of the element 8 does not exceed the size of the bird, which does not allow it to sit on the protruding section of the shelf 17.

The vertical shelf 16 of the angular profile of the mount 7 is equipped with inclined shelves 18 located along the bottom side 19 of the vertical shelf 16 at an angle to its plane and connected to the bottom of the vertical shelf 16 or directly to its bottom side 19. The shelves 18 are also located at an angle between them. , and the inner surfaces of the shelves 18 form an additional surface of contact with the outer surface of the profile of the carrier element of the contact network.

When performing a carrier element, for example, 2 with an outer cylindrical surface, the inner surfaces of the inclined shelves 18 are associated with the outer cylindrical surface of the carrier element (see Fig. 13 and 14).

On the outer planes of the plate of the element 8, stiffening ribs 20 of the plate can be made, directed from the lower side 11 of the plate to each of its tops 14.

On one outer surface of the vertical shelf 16 of the corner profile of the mount 7 can be made vertical stiffeners 21. In this case, the plane of the ribs 20 of the plate and the stiffeners 21 of the corner profile of the mount 7 coincide.

The described device is used as follows. The bird protection device is installed at the junctions of insulators 5 and 6 with bearing elements (brackets 2, main clamps 3 and horizontal rods or rods 4) supporting the contact network system, in particular, of railway transport. The need for such an installation is due to the occurrence of short circuits in the event of birds landing on flat areas of the specified bearing elements near insulators 5 and 6. Despite the use of special fixing bird-protected insulators in such systems, emergency situations still occur, although fixing bird-protected insulators have the largest insulating gap compared to with other fixing insulators of the railway contact network having the same creepage distance. The increased insulating gap, combined with the absence of places on the insulator that are convenient for placing the paws of large and medium-sized birds, provide a low probability of electrical flashing of the insulator when interacting with birds. Also, the increased insulating gap provides higher discharge characteristics compared to conventional insulators, which reduces the likelihood of flashovers not only due to the fault of birds, but also due to pollution or thunderstorms.

Installing a PZU next to isolator 5 or 6 prevents birds from landing on the area adjacent directly to the isolator. In this case, the bird cannot also sit on the ROM itself, since its anti-attachment element 8 is made in the form of a relatively thin plate, the thickness of which does not allow the bird's paws to fit along the width of the plate. The median plane of the plate is placed along the geometric longitudinal axis 10 of the bearing element. It is also impossible for a bird to place its paws along the plate, since the sides 12 of the plate are located perpendicular (vertically) or obliquely at an acute angle to the underside of the plate. It is also impossible to sit down inside the corner cutout 13 between the peaks 14. Thus, the described shape of the anti-attack element 8 of the ROM closes a place convenient for landing birds, but prevents them from landing on the element 8 itself. length to prevent the occurrence of the "bridge" effect even in the case of a bird landing on element 8. At the same time, the presence of an angular cutout 13 allows the use of a plate with a sufficiently extended side 11, selected based on the reliability of fixing the ROM on the carrier element using the described universal attachment 7 with sufficient length for this reliability. The transverse rigidity of the plate is ensured by its fastening along its entire length to the horizontal shelf 17 of the angular profile of the attachment unit 7. To ensure the rigidity of the thin plate of the element 8, it has stiffeners 20 either with sides inclined to the plate surface or parallel to it.

The design of the described 7 provides the possibility of reliable installation of the ROM on bearing elements with various cross-sectional shapes: corners with their different spatial position and with different shelf sizes, as well as channel and pipes of various diameters used in the installation of contact networks.

Thus, the use of the described universal mount makes it possible to increase the reliability of fastening bird protection devices of various types on the bearing elements of consoles with various shapes and sizes of these bearing elements by providing a high degree of versatility of the mount.
