The bird deterrent device includes a support rod 10 fixedly installed on the top plate 7. The upper end of the support rod 10 is provided with a base plate 11. The upper end of the base plate 11 is provided with a threaded rod 12. The upper end of the threaded rod 12 is provided with a top rotating rod 9. The top end of the top rotating rod 9 is provided with the top plate 7. A bushing is engaged with the threaded rod 12. Several connecting rods are evenly fixedly connected to the outer surface of the bushing. The ends of the connecting rods are fixedly connected with wind cups 8. The bushing can rotate on the threaded rod 12 and the top rotating rod 9. The diameters of the base plate 11 and the top plate 7 are larger than the inner diameter of the bushing. The length of the top rotating rod 9 is larger than the length of the bushing.

[0022] The first embodiment of this utility model is as follows:

[0023] A crossarm support for power cables includes a crossarm 2 with two elliptical holes 13 in the middle. A second clamp 5 is provided between the two elliptical holes 13 on the crossarm 2. The clamp assembly also includes a first clamp 1, which passes through the elliptical holes 13 and is engaged with a nut 4. During installation, the first clamp 1 is first wrapped around the utility pole, then the two screws at one end of the first clamp 1 are passed through the elliptical holes 13 on the crossarm 2, and finally tightened with the nut 4 to install the crossarm 2 on the utility pole. The crossarm 2 also has several mounting holes 3 through which insulating porcelain pots can be installed.

[0024] The crossbeam 2 is detachably equipped with a cover 6 assembly for preventing rainwater erosion. The cover 6 assembly includes a top plate 7, a vertical plate, and two side plates 14. The lower part of the top plate 7 is provided with a clamping edge 15. The top plate 7 and the clamping edge 15 cooperate to install the cover 6 assembly on the crossbeam 2. The top plate 7 and the vertical plate close the open side of the L-shaped steel crossbeam 2, while the side plates 14 close both ends, leaving only the lower end open, which can prevent rainwater erosion. The top plate 7 is provided with several notches 16, the positions of which correspond to the positions of the mounting holes 3, leaving positions for installing the insulating porcelain pot. At the same time, when the insulating porcelain pot is installed in place, the top plate 7 and the insulating porcelain pot are in close contact to prevent rainwater from flowing in.

[0025] The cover assembly 6 is equipped with a bird-repelling device, which includes a support rod 10 fixedly mounted on the top plate 7. A base plate 11 is mounted on the upper end of the support rod 10. A threaded rod 12 is mounted on the upper end of the base plate 11. A top rotating rod 9 is mounted on the upper end of the threaded rod 12. The top plate 7 is mounted on the top of the top rotating rod 9. A bushing is meshed with the threaded rod 12. Several connecting rods are evenly fixedly connected to the outer surface of the bushing. A wind cup 8 is fixedly connected to the end of the connecting rod. The bushing can rotate on the threaded rod 12 and the top rotating rod 9. The diameter of the base plate 11 and the top plate 7 is larger than the inner diameter of the bushing, and the length of the top rotating rod 9 is larger than the length of the bushing.

[0026] After installation, the bushing is located at the base plate 11. When wind blows, the air pressure on both sides of the wind cup 8 is different, driving the bushing to rotate. Under the action of the thread on the threaded rod 12, the bushing rotates and moves upward until it reaches the top rotating rod 9. The bushing can rotate freely on the top rotating rod 9. When there is no wind or a light wind, the bushing stops rotating. Under the action of gravity, its internal thread re-engages with the threaded rod 12, and the bushing rotates and falls back to the base plate 11. Because the bird deterrent device can move up and down, its effective range is expanded, improving the bird deterrent effect and preventing birds from building nests.

[0027] It should be noted that the terms "first, second, and third" used in this utility model are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0028] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
