For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Bird-proofing devices need to be installed in places such as transmission lines and transmission tower facilities of power facilities, because birds will choose to build nests and defecate on transmission line towers, causing line tripping, short circuits, etc., which is the main factor that poses a serious threat to transmission lines and needs to be prevented.

[0024] Example

[0025] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0026] A bird-proof spike comprises a pillar 403, the top of which is rotatably connected to a rotating platform 402, a plurality of extension rods 101 are fixedly connected to the outer edge of the rotating platform 402, a rotating base ring 301 is sleeved on the outer edge of each extension rod 101, a plurality of lateral spikes 302 are evenly arranged on the outer edge of each rotating base ring 301, and a fan blade 103 is arranged at one end of each extension rod 101 facing away from the rotating platform 402, and all the fan blades 103 are continuous, and a group of vertical spikes 401 are fixedly connected to the top side of the rotating platform 402. In this embodiment, the fan blades 103 have continuity, which means that the bending directions of all the fan blades 103 are connected to form a circle with the center of the rotating platform 402 as the center. Therefore, when the fan blades 103 are blown by the wind, the rotating platform 402 and the extension rod 101 will be driven to do circular motion, so that the lateral thorns 302 on the extension rod 101 will not face the wind blowing from the same direction for a long time, and the lateral thorns 302 are prevented from bending under the action of the wind. At the same time, the lateral thorns 302 and the rotating base ring 301 can also rotate under the action of the wind, further reducing the probability of the lateral thorns 302 bending. At the same time, the vertical thorns 401 are radially divergent outwards, and the vertical thorns 401 will not collide with the lateral thorns 302, and the vertical thorns 401 are used to rotate them, further driving away birds. In this embodiment, the bottom end of the pillar 403 is provided with a mounting frame 404 for installing the device.

[0027] Each extension rod 101 has a storage groove on the top side, and a block 102 is rotatably connected between the inner walls on both sides of each storage groove, and a support spring 104 is rotatably connected to the bottom side of each block 102, and the bottom end of each support spring 104 is connected to the bottom inner wall of the corresponding storage groove. Each bottom inner wall of the storage groove has a slide groove, and a slide 105 is slidably connected between the inner walls of each slide groove, and the top side of each slide 105 is rotatably connected to the bottom end of the corresponding support spring 104. In this embodiment, when the support spring 104 is not affected by external force, it will remain in a vertical state and keep the bottom side of the block 102 horizontal, and most of it will be pushed out of the storage groove, and both sides of the block 102 have inclined surfaces, which is convenient for the staff to press the block 102, so that the rotating base ring 301 can press the block 102 to be inserted into the extension rod 101.

[0028] The outer side of each extension rod 101 is fixedly connected with a circle of outer sleeve ring 203, each circle of outer sleeve ring 203 is closer to the rotating platform 402 than the corresponding block 102, and each circle of outer sleeve ring 203 is provided with a circle of outer sleeve slot on the side facing the corresponding block 102, and a circle of inner slip ring 202 is inserted between the inner walls of each circle of outer sleeve slot. A plurality of limit springs 204 are evenly fixedly connected to the side of each inner slip ring 202 facing the corresponding outer sleeve ring 203, and all limit springs 204 corresponding to the same inner slip ring 202 are fixedly connected to the inner wall of the corresponding outer sleeve slot, and each inner slip ring 202 is fixedly connected with a circle of positioning ring 201 on the side facing the corresponding block 102. Conical slots are provided on both sides of each rotating base ring 301, and the inner walls of the two slots corresponding to the same rotating base ring 301 are respectively matched with the outer walls of the corresponding block 102 and the positioning ring 201. In this embodiment, after the rotating base ring 301 and the positioning ring 201 are brought into contact, the positioning ring 201 is squeezed to shrink its limit spring 204, allowing the rotating base ring 301 to completely pass over the block 102, so that the block 102 pops out and fixes the rotating base ring 301. The surfaces of the positioning ring 201 and the block 102 are smooth, allowing the rotating base ring 301 to continue to rotate.

[0029] It should be noted that the utility model is a bird-proof spike. When in use, the support 403 is installed on the top of the power tower, and then each rotating base ring 301 is sleeved on the corresponding extension rod 101 to perform bird-proofing work.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
