Description

Technical Field

[0001] This application relates to the technical field of bird-related fault prevention for overhead transmission lines, and in particular to an extended anti-falling bird spike device for overhead transmission lines. Background Technology

[0002] Currently, bird-proofing devices for overhead transmission lines are mostly installed on the towers using bolt connections, relying on the principle of space occupation to restrict bird landing and thus deter birds. Because the conductor of the middle phase in a T-shaped tension tower is located below the overhead ground wire on the inner corner side, when birds perch on the overhead ground wire on the inner corner side of the tower, especially larger waterfowl or birds of prey, their droppings are large in volume and low in viscosity. As the droppings fall from their perch, they form continuous conductive columns that short-circuit part of the air gap between the overhead ground wire and the middle phase conductor, causing a discharge trip due to insufficient electrical distance. Statistics show that line trips caused by birds perching on the overhead ground wire account for more than 20% of all bird-related faults on overhead transmission lines in western Inner Mongolia.

[0003] Therefore, the solution proposed in existing patent CN206225949U addresses the aforementioned problems by installing bird spikes after connecting a support rod to the crossarm of the tower. However, long-term operational experience shows that bird spikes are prone to deformation after prolonged operation in windy regions such as northern areas, leading to larger gaps between the spikes and weakening the protective effect. Secondly, the support rod is structurally a cantilever beam, and under long-term wind-induced vibration, the bird spikes may fall off due to loose bolts, causing them to lose their protective function or directly trigger line faults. Furthermore, the fixed installation method of the main body of the bird spikes makes it difficult to flexibly adjust the installation position according to the size of the birds, reducing the protective effect. Utility Model Content

[0004] This application provides an extended anti-falling bird spike device for overhead transmission lines to solve the technical problems of the lack of effective bird protection devices near the ground wire hanging point of the T-shaped tension tower of overhead transmission lines and the fact that existing ground wire bird spike devices are prone to falling off and are difficult to flexibly adjust the installation position according to the size of birds, resulting in poor protection effect.

[0005] In view of this, this application provides an extended anti-falling bird spike device for overhead transmission lines, including a bird spike body and a horizontally arranged fixing rod. The bird spike body is provided with radial spikes. The fixing rod includes a wing plate, a web plate, and a base plate. The upper end face of the wing plate is fixedly connected to the lower end face of the bird spike body. The base plate is connected to the crossarm of the tower. The lower part of the bird spike body is provided with an installation part. The installation part includes an open ring-shaped connecting hardware integrally connected to the bird spike body and two threaded holes symmetrically arranged on the connecting hardware. The connecting hardware is nested on the wing plate. A first bolt is provided on the threaded hole. One end of the first bolt passes through the threaded hole and presses against the upper end face of the wing plate.

[0006] Optionally, the needles are of equal length.

[0007] Optionally, the needle is provided with a coiled spring in the middle.

[0008] Optionally, the fixing rod is an integral structure, and the cross-section of the fixing rod is I-shaped.

[0009] Optionally, both the crossarm of the tower and the base plate are provided with bolt through holes.

[0010] Optionally, a second bolt is provided through the bolt through hole, and the second bolt passes through the bolt through holes of the base plate and the tower crossarm from top to bottom and is connected with a nut.

[0011] Optionally, the lower end of the needle is fixedly connected to the upper end face of the bird thorn body.

[0012] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:

[0013] The overhead transmission line extended anti-falling bird spike device provided in this application consists of a bird spike body and a horizontally installed fixing rod. The bird spike body is equipped with radially arranged spikes. The fixing rod includes a wing plate, a web plate, and a base plate. The upper end face of the wing plate is fixedly connected to the lower end face of the bird spike body. The base plate is connected to the crossarm of the tower. The lower part of the bird spike body has an installation part, which includes an open ring-shaped connecting hardware integrally connected to the bird spike body and two threaded holes symmetrically arranged on the connecting hardware. The connecting hardware is nested on the wing plate. A first bolt is provided on the threaded hole. One end of the first bolt passes through the threaded hole and presses against the upper end face of the wing plate. The fixing rod fixes the bird spike body to the crossarm on the inner corner side of the tower, extending outward along the line direction, so that the bird spike body is located on the tower. Above the ground wire, the device prevents birds from roosting and resting on that area, solving the problem of the lack of effective bird-proofing devices on the inner corner of the ground wire of the current T-shaped tension tower. The bird spike body and the fixing rod are installed through the mounting part, which allows for flexible adjustment of the installation position of the bird spike body. It is connected by an open ring-shaped fitting and two threaded holes symmetrically arranged on the fitting. The fitting is nested on the wing plate, and a first bolt is provided on the threaded hole. One end of the first bolt passes through the threaded hole and presses against the upper surface of the wing plate, effectively reducing the risk of the bird spike body falling off due to bolt loosening after long-term operation. At the same time, the bird spike needle adopts a spring-loaded design, which enhances the needle's resistance to deformation in windy environments and improves the bird-proofing effect of the bird spike device. The overall structure of the device is simple, and the installation and adjustment are flexible and convenient. Attached Figure Description

[0021] For easier understanding, please refer to Figure 1An embodiment of the overhead transmission line extended anti-falling bird spike device provided in this application includes an anti-bird spike body 1 and a horizontally arranged fixing rod. The bird spike body 1 is provided with radially arranged spikes 2. The fixing rod includes a wing plate 6, a web plate 7, and a base plate 8. The upper end face of the wing plate 6 is fixedly connected to the lower end face of the bird spike body 1. The base plate 8 is connected to the crossarm 12 of the tower. The lower part of the bird spike body 1 is provided with an installation part. The installation part includes an open ring-shaped connecting hardware 3 integrally connected to the bird spike body 1 and two threaded holes 4 symmetrically arranged on the connecting hardware 3. The connecting hardware 3 is nested on the wing plate 6. A first bolt 5 is provided on the threaded hole 4. One end of the first bolt 5 passes through the threaded hole 4 and presses against the upper end face of the wing plate 6. The fixing rod fixes the bird spike body 1 to the crossarm on the inner corner side of the tower, extending outward along the line direction, so that the bird spike body 1 is located above the overhead ground wire, preventing birds from falling on the tower. This device, designed for birds to perch and roost on the ground wire, addresses the current problem of a lack of effective bird-proofing devices on the inner corner of the ground wire of T-shaped tension towers. The bird spike body 1 and the fixing rod are installed via an mounting section, allowing for flexible adjustment of the bird spike body 1's installation position. An open-ring connecting hardware 3 and two symmetrically arranged threaded holes 4 on the connecting hardware 3 are used. The connecting hardware 3 is nested on the wing plate 6, and a first bolt 5 is provided on each threaded hole 4. One end of the first bolt 5 passes through the threaded hole 4 and presses against the upper surface of the wing plate 6, effectively reducing the risk of the bird spike body 1 falling off due to bolt loosening after prolonged operation. This improves the bird-proofing effect of the bird spike device. Furthermore, the overall structure of the device is simple, and installation and adjustment are flexible and convenient. This solution addresses the technical problems of a lack of effective bird-proofing devices near the ground wire attachment point of T-shaped tension towers in overhead transmission lines, and the tendency of existing ground wire bird spike devices to easily fall off and the difficulty in flexibly adjusting their installation position according to the size of birds, resulting in poor protective effects.

[0022] Furthermore, the needles 2 are of equal length, which can effectively prevent birds from standing on the overhead ground line and improve the bird-proofing effect of the bird-proofing device.

[0023] Furthermore, the spike 2 is provided with a coiled spring 13 in the middle. The spike 2 adopts the form of a spring spike, which enhances the anti-deformation ability of the spike 2 in windy environments, improves the durability of the spike 2, and further improves the bird-proof effect of the bird spike device.

[0024] Furthermore, the fixing rod is an integral structure, which improves its stability. The cross-section of the fixing rod is I-shaped, which facilitates the installation of the fixing rod on the crossarm 12 of the iron tower, or the installation part is installed on the wing plate 6 of the fixing rod.

[0025] Furthermore, both the tower crossarm 12 and the base plate 8 are provided with bolt through holes 9. A second bolt 10 is inserted through the bolt through hole 9. The second bolt 10 passes through the bolt through holes 9 of the base plate 8 and the tower crossarm 12 from top to bottom and is connected with a nut 11. This allows the bolt through holes 9 of the base plate 8 and the tower crossarm 12 to be aligned when the fixing rod is installed on the tower crossarm 12. Then, the second bolt 10 passes through the bolt through holes 9 of the base plate 8 and the tower crossarm 12 from top to bottom. The end of the second bolt 10 that protrudes from the bolt through hole 9 of the tower crossarm 12 is connected to the nut 11 and tightened, which improves the connection stability between the fixing rod and the tower crossarm 12.

[0026] Furthermore, the lower end of the needle 2 is fixedly connected to the upper end face of the bird spike body 1, thereby improving the stability of the connection of the needle 2, preventing the needle 2 from falling off, and improving the durability of the needle 2.
