The wiping board 5 is of a fan-shaped structure, and the part of the wiping board 5, which can be overlapped with the reflecting shade 4, can shade the reflecting shade. Under the condition that sunlight exists in the daytime, the sunlight irradiates on the reflecting shade 4, the reflecting shade 4 reflects the sunlight and reflects the sunlight to the periphery, when birds fall on the electric wires, the reflected light irradiates on the eyes of the birds, so that the birds are stimulated, and the effect of driving the birds is achieved.

The wiping board 5 can shield the reflecting cover 4 at the overlapping part in the rotating process, once the reflecting cover is shielded, sunlight cannot irradiate on the reflecting cover 4, namely, the overlapping part of the reflecting cover 4 and the wiping board 5 cannot reflect sunlight, namely, no optical fiber irradiates the eyes of birds falling on the electric wire. And along with the rotation of the wiping board 5, the part of the reflecting shade 4, which is shielded, is exposed to sunlight, the sunlight can be continuously reflected, the reflected sunlight can irradiate on eyes of birds, and the dynamic sunlight reflection of the reflecting shade 4 can be realized by utilizing the rotation of the wiping board 5, so that the reflected sunlight is in a dynamic process of 'bright-dark-bright', and the generated dynamic light can generate larger stimulation to the birds, thereby achieving larger frightening effect to the birds and having better bird driving effect.

In the absence of sunlight, a separate light source is required to generate light to frighten the bird in order to achieve a good bird repellent effect. Therefore, the fixing frame 51 with a C-shaped structure is fixed on one side of the wiping board 5, the plurality of lamp beads 52 are mounted on the bottom side of the fixing frame 51, and the lamp beads 52 are connected in parallel, so that the fault tolerance of the circuit between the lamp beads 52 can be improved.

Through the relative rotation of the wiping board 5 between the reflectors 4, the cleaning board can wipe the surfaces of the reflectors 4, so that the side surfaces of the reflectors 4 can be kept bright, impurities on the surfaces of the reflectors 4 are avoided, and the light reflection effect of the reflectors 41 is affected.

The top surface of mount 51 is fixed with light sensor 53, the output of light sensor 53 is connected with singlechip 54, the output of singlechip 54 passes through the wire and is connected with lamp pearl 52, lamp pearl 52 is provided with a plurality ofly, and a plurality of lamp pearls 52 are arranged at the bottom surface annular equidistance of mount 51, light is weaker during daytime and when night, under the effect of light sensor 53, singlechip 54 can receive the power of excitation and closure lamp pearl 52, the light that sends when lamp pearl 52 is circular telegram can be reflected by reflector 4, and then realize the purpose of frightening the nearby airspace birds of cable.

In this embodiment, reflector 4 is round platform type structure, and the outer wall of reflector 4 is fixed with a plurality of reflector 41, and reflector 41 is isosceles trapezoid structure, and a plurality of reflector 41 are arranged at the outer wall annular equidistance of reflector 4, and the top of reflector 4 is bellied sphere type structure that makes progress, and the structure of curved surface can make the rainwater of rainwater weather can follow the top landing of reflector 4 fast, avoids the rainwater to gather in the top of reflector 4, appears the rainwater and gets into the inside condition of equipment compartment 1.

In this embodiment, since the distance between the poles or towers (or the moving contact net and the towers) is relatively long, at least at a distance of 100 meters, and once birds fall at a position between the two poles (i.e., relatively long from both poles), it is difficult for reflected light to be irradiated to such a long distance, and thus, in order to enhance bird repelling effect. The center department on equipment compartment 1 right side installs bull stick 2, and the end that bull stick 2 stretched out equipment compartment 1 is fixed with the striking disk 3, installs equipment compartment 1 in the top of support frame to make bull stick 2 be in the horizontal direction, can set up a plurality of bull sticks 2 in the inside of equipment compartment 1, and a plurality of bull sticks 2 are respectively along the setting of support frame side cable's direction, and guarantee that striking disk 3 can carry out the striking to the cable when rotating. The power output shaft of the motor 6 is connected with the end part of the rotating rod 2 far away from the striking disc 3 through a bevel gear 61, a connecting rod 62 is integrally arranged at the top end of the bevel gear 61 fixed with the power output shaft of the motor 6, the rotating rod 2 and the connecting rod 62 are driven to rotate when the motor 6 rotates, the rotating rod 2 drives the striking disc 3 to rotate outside the equipment compartment 1, the striking disc 3 strikes a cable, and the cable vibrates.

The striking plate 3 comprises a fixed plate 31 and a plurality of striking rods 32, the center of the side surface of the fixed plate 31 is fixed with the end part of the rotating rod 2, the striking rods 32 are annularly and equidistantly arranged on the outer wall of the fixed plate 31, the striking rods 32 are of hollow structures, a plurality of small holes are formed in the striking rods 32 and serve as sound holes, when the striking rods 32 are in contact with electric wires, vibration is generated under the action of impact force, sound is emitted, and meanwhile, the electric wires are carried to vibrate, namely, when the fixed plate 31 rotates, the striking rods 32 strike the electric wires, so that the cables vibrate, noise generated by the vibration of the cables is low, the vibration generated by the cables is generated by the cables, the sound generated by the vibration of the cables is firstly transmitted to birds, the birds are frightened, and the birds fly away from the electric wires, as shown in a of fig. 4. The striking rod 32 and the wire collide and the striking rod 32 vibrates to generate noise, and the sound is rapidly transmitted to the wire and along the wire to secondarily frighten the bird due to the direct contact of the striking rod 32 and the wire, as shown in fig. 4 b. At the same time, the sound hole will release the sound generated when the striking rod 32 is struck to the outside into the air and propagate in the air as shown in fig. 4 c. Because the vibration of the cable firstly generates sound, birds falling on the electric wire are frightened, and the birds fly away from the electric wire; while the sound propagates in the solid at a greater rate than in air, the noise from striking the rod 32 is then transmitted to the birds via the wires, which secondarily startles the birds, causing them to fly further away. Since the speed of sound propagation in air is the smallest, (the range of propagation is spherical, the range is the largest) and finally the sound is transmitted into the ears of birds, and the birds are frightened for the third time, so that the birds fly farther. The bird repellent effect is better by adopting a multiple startle mode. The sound source gradually spreads from the cable body to the external sound source, as shown by the arrow in fig. 4, that is, the manner of excitation of the sound source is matched with the manner of flying away of birds (that is, when birds fly away from the cable, the direction of the arrow in fig. 4 is gradually far away from the cable), and the three startle orders of the sound source and the sound in the embodiment are also gradually far away from the direction of the cable, so that the bird-driving-away effect is better.

And three times of driving-off sounds are generated in order from the wire body (the smallest sound range) to the sound transmitted by the wire (the second largest sound range) and finally to the surrounding environment (the largest sound range), that is, birds are separated from the wire when the wire body vibrates. Under the effect of the sound transmitted by the electric wire, birds can fly away further, and finally the sound generated by the environment enables the birds to fly farther, so that the birds can be far away from the electric wire more quickly. Compared with a single expelling mode, the mode of the embodiment has the advantages that the level of the sound source is gradually far away from the electric wire, the expelling mode of birds is also gradually far away from the electric wire, and the expelling effect of birds is better.

In addition, noise generated when the striking rod 32 is struck is discharged to the air through the sound hole, so that birds are prevented from winding around the cable, and the birds can be prevented from staying on the cable through vibration of the cable.

In further embodiments, the fixing disc 31 and the striking rod 32 are made of acrylonitrile, the two reinforcing rods 33 are integrally arranged on the outer wall of the striking rod 32, the two reinforcing rods 33 are symmetrically arranged along the diameter direction of the striking rod 32, the toughness of the striking rod 32 can be improved through the reinforcing rods 33, the service life of the striking rod 32 is further prolonged, the strength of the striking rod 32 can be improved, the amplitude of a cable when the striking rod 32 strikes the cable can be improved, and the bird repelling effect is further improved.
