DETAILED DESCRIPTION

[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0018] like Figure 1 to Figure 2 In one embodiment of the overhead line bird-repelling device of the utility model, the device comprises a fixed mounting seat 1, a column 11 fixed on the mounting seat 1, and a bird-repelling frame 2 hinged on the column 11, characterized in that the bird-repelling frame 2 comprises a driving seat 21 that can slide up and down along the column 11, a first rotating disk 22 hinged on the driving seat 21, a plurality of hanging rods 25 fixed on the outer wall of the first rotating disk 22, a wind bucket 23 fixed at the end of the hanging rod 25, and a reflector 24 arranged in the wind bucket 23; a vertically arranged first reflector 231 is arranged in one wind bucket 23; a second reflector 232 with a mirror surface tilted upward is arranged in at least one wind bucket 23; and a third reflector 233 with a mirror surface tilted downward is arranged in at least one wind bucket 23. By arranging the reflectors facing upward, middle, and downward respectively, the disturbing range of the bird-repelling device to flying birds is effectively expanded.

[0019] Specifically, the angle between the mirror surface of the second reflector 232 and the vertical plane is 10°~20°; the angle between the mirror surface of the third reflector 233 and the vertical plane is 10°~35°.

[0020] Specifically, a deceleration device 4 is provided on the column 11; the deceleration device 4 includes a deceleration frame 5 hinged on the column 11 and placed on the lower side of the bird-repelling frame 2, and an isolation magnetic block 41 fixed on the top surface of the column 11; the deceleration frame 5 includes a frame seat 51 arranged on the lower side of the bird-repelling frame 2 and capable of sliding up and down along the column 11, a second turntable 52 hinged on the frame seat 51, a plurality of fan blades 53 fixed on the outer wall of the second turntable 52, and a wind plate 54 fixed on the end of the fan blade 53; a driving magnetic block 26 is provided on the first turntable 22; a deceleration magnetic block 55 for repelling and supporting the driving magnetic block 26 is provided on the second turntable 52; and the isolation magnetic block 41 and the driving magnetic block 26 are arranged to repel each other. By designing a deceleration device for repelling and suspending the bird-repelling frame, under the action of strong winds, the deceleration frame obtains upward lifting force during rotation, repelling and squeezing the bird-repelling frame, reducing the rotation speed of the bird-repelling frame, and reducing the wear of the equipment affected by the strong wind.

[0021] Specifically, a support magnetic block 12 is provided on the mounting seat 1 to support the deceleration frame 5 to suspend upward.

[0022] Specifically, the direction of the plate surface of the wind plate 54 is opposite to the direction of the opening of the wind scoop 23 .

[0023] Specifically, a plurality of slideways 13 are vertically disposed on the column 11 ; and pulleys that can slide in the slideways 13 are disposed on the driving seat 21 and the frame seat 51 .

[0024] Specifically, a plurality of wind whistles 3 are provided on the hanging rod 25 ; the openings of the wind whistles 3 are oriented in the opposite direction to the openings of the wind scoops 23 .

[0025] Specifically, the difference in the distance between adjacent wind whistles 3 and posts 11 is an integer multiple of (length of suspension rod 25 / number of suspension rods 25); the distance between adjacent wind whistles 3 and posts 11 is not equal. The length of the suspension rod is L, the number of suspension rods is N, and the distance between any wind whistle and the post is A0, A1, A2, etc., then the formula A0-A1=(L / N)*X is satisfied, where X is an integer. By setting wind whistles with different distances from the posts, different sounds are formed in the natural wind, and the sounds formed by the combination are different in different weather conditions, wind speeds, and rotation speeds of the bird-repelling racks, which effectively increases the frequency band of the sound that drives away and disturbs flying birds and reduces the risk of birds adapting to constant sounds.

[0026] Working principle: After the staff installs the equipment at the preset position, the deceleration frame 5 is placed in a suspended state under the repulsive force support of the supporting magnetic block 12, and the bird-repelling frame 2 is placed in a suspended state under the repulsive force support of the deceleration magnetic block 55. Under the action of natural wind, the wind bucket 23 is blown to rotate, and the first light-emitting mirror 231 reflects horizontal light to disturb the surrounding birds, the second reflector 232 reflects upward light to disturb the upper birds, and the third reflector 233 reflects downward diffused light to disturb and drive away the lower birds, effectively expanding the range of driving away the surrounding birds. During the rotation of the bird-repelling frame 2, the natural wind speed changes arbitrarily to drive the rotation speed of the bird-repelling frame 2 to change, and multiple wind whistles 3 with inconsistent spacing from the columns 11 make different sounds during rotation, and the sound combination of multiple wind whistles 3 , a continuously changing sound is emitted in the blowing of natural wind, which continuously disturbs and drives away the surrounding birds, and prevents the birds from forming tolerance to the continuous and unchanging sound. In windy weather, the wind plate 54 drives the reduction frame 5 and the bird-repelling frame 2 to rotate rapidly in the opposite direction, and the rotating multiple fan blades 53 drive the reduction frame 5 to rise upward, and cooperate with the isolation magnetic block 41 on the top to perform magnetic repulsion and extrusion on the bird-repelling frame 2, ensuring that the bird-repelling frame 2 is in a suspended state and does not contact the isolation magnetic block 41 and the reduction frame 5, and realizes interference with the rotation speed of the bird-repelling frame 2, reducing the rotation speed of the bird-repelling frame 2. The greater the wind force, the greater the upward lift of the reduction frame 5, the greater the repulsion force on the bird-repelling frame 2, and the more obvious the deceleration effect of the bird-repelling frame 2, which effectively reduces the wear of the bird-repelling frame 2 during rapid rotation in windy weather and ensures the service life of the equipment.
