Description

Technical Field

[0001] This utility model relates to the field of bird-proof spike technology, specifically bird-proof spikes for power transmission lines. Background Technology

[0002] In recent years, with the improvement of the ecological environment and the increased awareness of wildlife protection, bird activity has become more frequent, and the number of overhead transmission line faults caused by bird activity has also increased significantly. Bird-related faults in overhead transmission lines are characterized by several features, including pronounced seasonality, frequent occurrences at specific times, and a high degree of suddenness. Based on the bird-related fault risk distribution map, the power sector needs to equip overhead transmission line bundles with appropriate bird-proofing devices.

[0003] Bird spikes are a commonly used bird protection device for power transmission lines. They are inexpensive, easy to install, and can prevent birds from perching on the poles equipped with bird spikes, thus providing a certain degree of bird protection. Traditional bird spikes are usually made of multiple metal rods that unfold to prevent birds from landing on the power transmission line. In order to facilitate transportation, bird spikes are usually folded together before installation and then broken apart one by one before use. This not only wastes time but may also cause them to tangle together, affecting their effectiveness. Utility Model Content

[0004] The purpose of this invention is to provide bird spikes for power transmission lines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bird spike for power transmission lines, including a mounting base, and further comprising:

[0006] A connecting rod is fixedly connected to the top of the mounting base. A tapered cylinder is installed on the connecting rod. A groove is opened inside the tapered cylinder. A connecting block is rotatably connected inside the groove. A needle is fixedly connected to the connecting block.

[0007] A conical sleeve is snapped onto the outside of a conical cylinder, and a limiting groove is formed on the inner wall of the conical sleeve, with the needle located inside the limiting groove.

[0008] Preferably, the tapered sleeve is internally threaded with bolts, and the tapered cylinder has internally threaded holes.

[0009] Preferably, a fixing rod is fixedly connected to the top of the conical cylinder, and a through groove is opened inside the conical sleeve, into which the fixing rod is inserted.

[0010] Preferably, a connecting sleeve is rotatably connected to the top of the connecting rod, and the conical cylinder is fixedly connected to the top of the connecting sleeve.

[0011] Preferably, a number of fan blades are fixedly connected to the outer side of the conical cylinder.

[0012] Preferably, the mounting base has two symmetrical screws connected by internal threads, and the mounting base is provided with anti-slip grooves.

[0013] Preferably, two sets of the conical cylinder and the conical sleeve are provided, and the size of the upper conical cylinder and the conical sleeve is smaller than the size of the lower conical cylinder and the conical sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention moves the position of the conical sleeve, causing the limiting groove to move outside the conical cylinder. During this movement, the limiting groove pushes the needles, which in turn rotate the connecting block in the groove until the connecting block moves downward and engages with the edge of the groove, thus unfolding the needles and achieving the purpose of repelling birds. Each needle is installed in a separate groove, which can prevent the needles from getting tangled together. The conical cylinder rotates through the connection between the connecting sleeve and the connecting rod. Natural wind blows the fan blades, causing the conical cylinder to rotate, which in turn causes the needles to rotate, thus improving the bird-repelling effect. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 As shown, the bird spikes for power transmission lines include a mounting base 1, which is C-shaped, and a connecting rod 2, which is fixedly connected to the top of the mounting base 1. A conical cylinder 3 is mounted on the connecting rod 2. The conical cylinder 3 has several grooves 5 arranged in a ring on the conical cylinder 3. A connecting block 6 is rotatably connected inside the grooves 5. A spike 7 is fixedly connected to the connecting block 6. The connecting block 6 can drive the spike 7 to rotate in the grooves 5 to adjust the angle of the spike 7. A conical sleeve 4 is snapped onto the outside of the conical cylinder 3. A limiting groove 8 is opened on the inner wall of the conical sleeve 4. The spike 7 is located inside the limiting groove 8. The movement of the conical sleeve 4 on the conical cylinder 3 drives the limiting groove 8 to move up and down. During the movement, the limiting groove 8 pushes the spike 7 to move, thereby completing the unfolding and retraction of the spike 7.

[0024] It should be noted that: the conical cylinder 3 and the conical sleeve 4 are installed on the mounting frame of the power transmission line through the mounting base 1. By moving the position of the conical sleeve 4, the limiting groove 8 is moved to the outside of the conical cylinder 3. During the movement, the limiting groove 8 pushes the barbed needle 7 to move. The barbed needle 7 drives the connecting block 6 to rotate in the groove 5 until the connecting block 6 moves downward and locks into the edge of the groove 5, so that the barbed needle 7 unfolds and achieves the purpose of bird deterrence. Each barbed needle 7 is installed in a separate groove 5, which can prevent the barbed needles 7 from getting tangled together.

[0025] The conical sleeve 4 is internally threaded with a bolt 9, and the conical cylinder 3 has a threaded hole 10 inside. After the conical sleeve 4 moves down to its position, the bolt 9 is installed into the threaded hole 10, thereby fixing the conical sleeve 4 onto the conical cylinder 3. The positions of the limiting groove 8 and the needle 7 are determined. If the conical sleeve 4 moves upward to retract the needle 7, the bolt 9 moves into the conical sleeve 4 and engages with the outside of the conical cylinder 3, thus limiting the position of the conical sleeve 4. A fixing rod 11 is fixedly connected to the top of the conical cylinder 3. The conical sleeve 4 has a through groove 12 inside, and the fixing rod 11 is inserted into the through groove 12. When the conical sleeve 4 moves, the through groove 12 moves outside the fixing rod 11, thus limiting the movement path of the conical sleeve 4.

[0026] A connecting sleeve 14 is rotatably connected to the top of the connecting rod 2, and a conical cylinder 3 is fixedly connected to the top of the connecting sleeve 14; several fan blades 13 are fixedly connected to the outside of the conical cylinder 3; the conical cylinder 3 rotates between the connecting sleeve 14 and the connecting rod 2, and the fan blades 13 are blown by the natural wind to drive the conical cylinder 3 to rotate, and the conical cylinder 3 drives the needle 7 to rotate, which can improve the bird repelling effect.

[0027] The mounting base 1 has two symmetrical screws 15 connected by internal threads. The mounting base 1 is provided with anti-slip grooves 16. The mounting base 1 is snapped onto the power transmission frame, and the screws 15 are tightened to snap into the power transmission frame, thereby fixing the mounting base 1 onto the power transmission frame. The anti-slip grooves 16 can increase the friction between the mounting base 1 and the power transmission frame, thereby improving the firmness of the mounting base 1.

[0028] Two sets of conical cylinders 3 and conical sleeves 4 are provided, and the size of the upper conical cylinder 3 and conical sleeve 4 is smaller than that of the lower conical cylinder 3 and conical sleeve 4. The upper and lower sets of conical cylinders 3 and conical sleeves 4 have the same structure, only different sizes. The bottom of the upper conical cylinder 3 is fixedly connected to the fixing rod 11 at the top of the lower conical cylinder 3 (the size of the fixing rod 11 and the through groove 12 is also proportionally reduced according to the size of the conical cylinder 3 and conical sleeve 4).

[0029] Working principle: The mounting base 1 is snapped onto the power transmission frame, and the screw 15 is tightened to engage with the power transmission frame, thus fixing the mounting base 1 onto the power transmission frame. The conical sleeve 4 is initially located at the upper part of the conical cylinder 3, retracting the spikes 7. During use, by moving the position of the conical sleeve 4, the limiting groove 8 is moved to the outside of the conical cylinder 3. During the movement of the limiting groove 8, the spikes 7 are pushed to move. The spikes 7 drive the connecting block 6 to rotate in the groove 5 until the connecting block 6 moves downward and engages with the edge of the groove 5, causing the spikes 7 to unfold, achieving the purpose of bird repelling. Each spike 7 is installed in a separate groove 5, which can prevent the spikes 7 from getting tangled together. The conical cylinder 3 rotates between the connecting sleeve 14 and the connecting rod 2. The natural wind blows the fan blade 13 to drive the conical cylinder 3 to rotate, and the conical cylinder 3 drives the spikes 7 to rotate, which can improve the bird repelling effect.
