AI Technical Summary
Conventional bird deterrents have a relatively short effective bird deterrent duration, mainly due to increased resistance in the bearings, resulting in excessive rotational resistance.
The structure uses a magnetic ring to drive the rotating frame. The repulsive force between the second and first magnetic rings reduces the force exerted by the guide sleeve on the bearing, thereby reducing rotational resistance and extending the bird-repelling time of the wind shield.
By reducing rotational resistance, the effective bird-repelling time of the wind shield is increased, the bearings are protected from particulate matter intrusion, and the service life of the device is extended.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power equipment technology, and in particular relates to a bird protection device for power transmission lines. Background Technology
[0002] Bird deterrence, also known as bird shooing, bird prevention, or bird strike prevention, broadly refers to any means of preventing harmful birds from entering one's territory and endangering one's work or equipment, such as farms, orchards, wind power plants, and military and civilian airports. Bird deterrence devices used on utility poles mainly use wind power to drive mirrors to rotate, thereby driving away birds and protecting power transmission safety.
[0003] As the bearing bears greater load, the resistance it experiences also increases. Since the rotational weight of a conventional bird repeller acts entirely on the bearing, the rotational resistance increases, resulting in a relatively short effective bird repeller duration.
[0004] Therefore, we propose a bird protection device for power transmission lines to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to solve the problem that conventional bird deterrents have a relatively short effective bird deterrent time, and to propose a bird-proof device for power transmission lines.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A bird-repellent device for power transmission lines includes a hanger. A bearing is fixedly connected to the lower inner wall of the hanger. A guide sleeve is fixedly connected to the inner ring of the bearing. A first magnetic ring is provided on the upper side of the bearing. The guide sleeve does not contact the first magnetic ring. The first magnetic ring is fixedly connected to the hanger. A rotating shaft is slidably installed inside the guide sleeve. A second magnetic ring is fixedly connected to the upper part of the rotating shaft. The second magnetic ring and the first magnetic ring repel each other. A rotating frame is fixedly connected to the lower end of the rotating shaft. A wind shield is fixedly connected to the outer end of the rotating frame. A reflective lens is fixedly connected inside the wind shield. After the hanger is installed on the target power pole, wind force acts on the wind shield and reflective lens, causing the wind shield to rotate the rotating frame. The rotating frame drives the rotating shaft to rotate, which in turn drives the guide sleeve to rotate. The repulsion between the second and first magnetic rings reduces the force exerted by the guide sleeve on the bearing, thereby reducing the rotational resistance of the guide sleeve and the rotating shaft, increasing the rotation time of the wind shield, and thus increasing the effective bird-repelling time of the wind shield.
[0008] Preferably, the upper sides of the second and first magnetic rings are covered with anti-fouling covers, and the lower ends of the anti-fouling covers are fixedly connected to the hanger. By covering the upper sides of the second and first magnetic rings with anti-fouling covers, the upper gap of the bearing is blocked, preventing particulate matter from entering the bearing from the upper side, thus facilitating the protection of the bearing.
[0009] Preferably, the hanger includes a frame and a tubular shell. The tubular shell is fixedly connected to the lower part of the frame, the bearing is externally fixedly connected to the lower inner end of the frame, and the first magnetic ring is externally fixedly connected to the upper inner end of the frame. The tubular shell stabilizes the distance between the first magnetic ring and the bearing.
[0010] Preferably, the hanger further includes a mounting base, which is fixedly connected to the upper end of the frame. Screws are passed through the mounting base to install the hanger onto the target utility pole.
[0011] Preferably, the guide sleeve includes a sleeve body, which is fixedly connected to the inner ring of the bearing. A guide groove is formed inside the sleeve body, and the rotating shaft is slidably mounted within the guide groove. The guide groove guides the rotating shaft to slide, allowing the weight of the rotating frame, wind shield, and reflector to act on the second magnet ring through the rotating shaft. This weight, in turn, suspends the weight of the first magnet ring, thereby reducing the bearing load and facilitating a reduction in rotational resistance.
[0012] Preferably, the rotating shaft includes a fixed disk, a connecting rod, and a sliding column. The lower end of the fixed disk is fixedly connected to the upper end of the second magnetic ring, the connecting rod is fixedly connected to the inner end of the second magnetic ring, and the lower end of the connecting rod is fixedly connected to the upper end of the sliding column. The sliding column is slidably inserted into the guide groove. The gravity of the rotating frame acts on the lower end of the sliding column, which in turn acts on the connecting rod, and then on the second magnetic ring through the connecting rod and the fixed disk, facilitating the transfer of negative forces on the bearing.
[0013] In summary, the technical effects and advantages of this utility model are as follows:
[0014] 1. After the hanger is installed on the target utility pole, the wind force acts on the wind shield and reflector, causing the wind shield to drive the rotating frame to rotate. The rotating frame drives the rotating shaft to rotate, which in turn drives the guide sleeve to rotate. The second and first magnetic rings repel each other, reducing the force of the guide sleeve on the bearing, thereby reducing the rotational resistance of the guide sleeve and the rotating shaft, increasing the rotation time of the wind shield, and thus increasing the effective bird-repelling time of the wind shield.
[0015] 2. Use a dirt cover to cover the upper side of the second and first magnet rings to block the upper gap of the bearing, prevent particles from entering the bearing from the upper side, and protect the bearing.
[0016] 3. The guide groove guides the rotating shaft to slide, so that the weight of the rotating frame, wind shield and reflector acts on the second magnet ring through the rotating shaft. The second magnet ring suspends the first magnet ring, thereby reducing the bearing load and reducing the rotational resistance.
[0017] 4. The gravity of the rotating frame acts on the lower end of the sliding column, which in turn acts on the connecting rod, and then on the second magnetic ring through the connecting rod and the fixed plate, thus facilitating the transfer of the negative force on the bearing.

[0025] Reference Figure 1 The upper sides of the second magnet ring 7 and the first magnet ring 8 are covered with a dirt cover 10, and the lower end of the dirt cover 10 is fixedly connected to the hanger 2. The dirt cover 10 covers the upper side of the second magnet ring 7 and the first magnet ring 8, blocking the upper gap of the bearing 9.
[0026] Reference Figure 1 and 2 The hanger 2 includes a frame 21 and a tubular shell 22. The tubular shell 22 is fixedly connected to the lower part of the frame 21. The outer part of the bearing 9 is fixedly connected to the lower inner end of the frame 21, and the outer part of the first magnetic ring 8 is fixedly connected to the upper inner end of the frame 21. The tubular shell 22 is used to stabilize the distance between the first magnetic ring 8 and the bearing 9.
[0027] Reference Figure 1 and 2 The hanger 2 also includes a mounting base 23, which is fixedly connected to the upper end of the frame 21. Screws are passed through the mounting base 23 to install the hanger onto the target utility pole.
[0028] Reference Figure 1 and 3 The guide sleeve 3 includes a sleeve body 31, which is fixedly connected to the inner ring of the bearing 9. A guide groove 32 is provided inside the sleeve body 31, and the rotating shaft 4 is slidably installed in the guide groove 32. The guide groove 32 guides the rotating shaft 4 to slide, so that the weight of the rotating frame 1, the wind shield 5 and the reflector 6 acts on the second magnet ring 7 through the rotating shaft 4. The second magnet ring 7 suspends the first magnet ring 8, thereby reducing the load on the bearing 9.
[0029] Reference Figure 1 , 3 The rotating shaft 4 includes a fixed disk 41, a connecting rod 42, and a sliding column 43. The lower end of the fixed disk 41 is fixedly connected to the upper end of the second magnet ring 7, the connecting rod 42 is fixedly connected to the inner end of the second magnet ring 7, and the lower end of the connecting rod 42 is fixedly connected to the upper end of the sliding column 43.

[0030] Working principle: After the hanger 2 is installed on the target utility pole, the wind force acts on the wind cover 5 and the reflector 6, causing the wind cover 5 to drive the rotating frame 1 to rotate. The rotating frame 1 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the guide sleeve 3 to rotate. By using the repulsion between the second magnet ring 7 and the first magnet ring 8, the force of the guide sleeve 3 on the bearing 9 is reduced, thereby reducing the rotational resistance of the guide sleeve 3 and the rotating shaft 4, increasing the rotation time of the wind cover 5, and thus increasing the effective bird-repelling time of the wind cover 5.
