Description

Technical Field

[0001] The present invention relates to the technical field of power transmission line safety, and in particular to a hinged-axis bird-proofing device and a bird-proofing method for power transmission lines. Background Art

[0002] The hazards posed by bird activity to the stable operation of power transmission lines have always been a major concern for the power industry. As critical infrastructure for power transmission, the safety of transmission lines is directly linked to the reliability and stability of power supply. Birds resting on transmission lines, nesting, and other behaviors can cause line failures, resulting in power outages and significant disruption to production and people's lives. Therefore, the design of effective bird-prevention devices for transmission lines is crucial.

[0003] Transmission line bird deterrents are devices installed on transmission lines to prevent birds from resting, nesting, and potentially causing line failures. Currently, two common methods are used for bird deterrents on transmission lines: metal spikes installed above the insulator towers, and polymer bird deterrent panels. Metal spikes rely on outward-extending spikes to deter birds, while polymer bird deterrent panels, with their plate-like structure, intercept bird droppings, thereby preventing line failures caused by bird droppings.

[0004] Research has revealed deficiencies in existing bird-proofing devices used on power transmission lines. Large migratory birds have long legs, reaching up to 1.5 meters, often exceeding the protection of existing bird spikes. This allows them to roost between loosely installed spikes. Furthermore, during their breeding season, large migratory birds nest in locations such as tower crossarms and ground wire supports. Since many of these birds are classified as Class I or Class II protected species, operators lack effective methods for clearing their nests. This has led to a sharp increase in bird-related failures on power transmission lines, seriously threatening the safe and stable operation of transmission lines, increasing maintenance costs, and reducing power supply reliability.

[0005] In addition, the bird-proofing devices in the existing technology are mostly fixed structures and cannot be adjusted according to the different types of birds. Birds in different regions are different, and the gripping force of different types of birds is also different. The existing technology cannot be adaptively adjusted according to the different types of birds, and its applicability is not strong. In addition, the existing bird-proofing devices are not easy for workers to disassemble after installation. Summary of the Invention

[0006] In response to the shortcomings of the existing technology, the present invention provides a hinged-axis bird-proofing device and a bird-proofing method for power transmission lines.

Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0030] Example 1

[0031] The present invention provides a hinged-axis bird-proofing device for power transmission lines, which is used for preventing birds at the angle steel position of the cross arm of the power transmission line. Bird-proofing spikes are installed on the angle steel of the power transmission line, and the bird-proofing device is installed between the two bird-proofing spikes. Figure 1 As shown, the bird-proofing device includes a triangular inclined surface structure and a hinge shaft, wherein the hinge shaft can rotate freely and is rotatably installed at the top of the triangular inclined surface structure. The hinge shaft is used to adjust the inclined surface angle of the triangular inclined surface structure, and the triangular inclined surface structure rotates around the hinge shaft; the bottom end of the triangular inclined surface structure covers the surface of the transmission line angle steel, making it difficult for birds to stay, fundamentally reducing the possibility of birds staying at the cross-arm angle steel position of the transmission line, and reducing the risk of bird damage.

[0032] In this embodiment, the surface of the triangular inclined surface structure is smooth, which can effectively prevent birds from stopping and staying; and two connecting holes are respectively provided on the two bottom ends of the triangular inclined surface structure, which are connected to the bird-releasing spikes and are used to install the bird-proofing device between the bird-proofing spikes. On the one hand, the opening of the connecting holes can reduce the number of installation holes on the tower material, and on the other hand, it can form a combined bird-proofing device with the bird-proofing spike structure, so that the gaps between the bird-proofing spikes are inclined, combined with the smooth inclined surface, and the entire bird-proofing device covers the horizontal surface of the angle steel where birds can stop, making it difficult for even birds with long legs to stop, thereby fundamentally reducing the possibility of birds stopping at the cross-arm angle steel position of the transmission line and reducing the risk of bird damage.

[0033] In this embodiment, the bird-proofing device also includes a screw, and fixing holes are opened at the center positions of the two inclined surfaces of the triangular inclined surface structure. The screw passes through the fixing holes. When the screw is locked, the triangular inclined surface structure is pressed and fixed by the locking force of the screw; wherein, an internal thread is provided on the inner side of the fixing hole, and the internal thread matches the thread on the screw.

[0034] The screw is fitted with an adjusting nut, which is positioned inside the triangular slope. The bird-proofing device also includes an angled washer. When the screw is tightened, the adjusting nut forms an angle with the slope. The washer is installed between the adjusting nut and the sloped surface inside the triangular slope to further secure the adjusting nut. The screw, adjusting nut, and angled washer, combined with the fixing holes, facilitate installation and removal, improving the efficiency of tower maintenance workers. The angled washer also enhances the tightness of the nut, ensuring the stability of the device.

[0035] Based on the hinged-axis bird-proofing device for a power transmission line provided in this embodiment, the specific bird-proofing method is as follows:

[0036] The bevel angle of the triangular bevel structure is adjusted by the hinge shaft, and the bottom end of the triangular bevel structure is covered on the surface of the transmission line angle steel; the bird-proof spikes on the angle steel are connected through the connection holes at the bottom end of the triangular bevel structure, and the triangular bevel structure is installed on the gaps between the bird-proof spikes; the triangular bevel structure is secondarily fixed through the fixing holes on the triangular bevel structure with screws, adjusting nuts and bevel washers; and the structure is used to place birds between the bird-proof spikes.

[0037] Among them, the screw passes through the fixing hole and is used to quickly disassemble the bird-proofing device. When the screw is locked, the adjusting nut is placed on the inner side of the triangular inclined surface structure, and an inclined gasket is installed between the adjusting nut and the inclined surface inside the triangular inclined surface structure; when disassembling the bird-proofing device, rotate the adjusting nut to separate the screw from the fixing hole.

[0038] In this embodiment, the gripping force of the bird is obtained, and according to the gripping force of the bird, the bevel angle of the triangular bevel structure is adjusted to the optimal bird-proofing angle through the hinge shaft. It can also be adjusted according to the size of the angle steel of the cross-arm tower material of the transmission line. This allows the present invention to flexibly set the optimal bird-proofing angle when facing different regions and different types of birds, thereby improving the applicability of the bird-proofing device.

[0039] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
