Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bird protection equipment for power lines, and in particular to a novel bird protection device for power lines. Background Technology
[0002] To address the problem of bird damage to power transmission lines, we need to take a series of effective measures. First, we must strengthen the inspection and maintenance of the lines to promptly identify and address safety hazards such as bird nests. Simultaneously, we can adopt advanced bird-proofing technologies, such as installing bird spikes, to prevent birds from approaching the power transmission lines.
[0003] However, existing bird spikes are often fixed in place. After a period of time, birds will adapt to the unchanging bird-proofing devices, resulting in a loss of bird-proofing effect. Utility Model Content
[0004] In view of this, the present invention provides a novel bird-proof device for power lines, the main purpose of which is to provide a dynamic bird-proof spike device to improve the bird-proofing effect.
[0005] To achieve the above objectives, this utility model mainly provides the following technical solutions:
[0006] This utility model provides a novel bird-proof device for power lines, which includes: a support rod, a bird-proof mechanism, and a drive mechanism;
[0007] The support rod is mounted to the crossarm of the tower via bearings;
[0008] The bird-proof mechanism includes a hollow sphere and multiple bird spikes. The hollow sphere is fixedly connected to the upper end of the support rod, and the central axis of the support rod coincides with the center of the hollow sphere. The multiple bird spikes are evenly distributed on the surface of the hollow sphere.
[0009] The drive mechanism includes a balance bar and two hemispherical panels. The center of the balance bar is fixedly connected to the lower end of the support rod, and the edges of the two hemispherical panels are respectively fixedly connected to the opposite ends of the balance bar. The two hemispherical panels are symmetrical about the center of the support rod.
[0010] The purpose of this utility model and the technical problems to be solved can be further achieved by the following technical measures.
[0011] Optionally, a rain cap is also included, which is fixedly connected to the side of the support rod between the hollow ball and the bearing.
[0012] Optionally, it also includes a solid sphere, which is fixedly connected to the inner surface of the hollow sphere, and the horizontal plane of the solid sphere coincides with the center of the hollow sphere.
[0013] Optionally, it also includes a U-shaped frame, the outer edge of which is fixedly connected to the outer ring of the bearing, the inner edge of which fits into the crossarm of the tower, and the side wall of the U-shaped frame is provided with screw holes for threaded connection of bolts so that the bolts abut against the crossarm of the tower.
[0014] Optionally, the hollow sphere, the support rod, the balance bar, and the two hemispherical panels are made of aluminum alloy.
[0015] Optionally, the lengths of the various bird spikes may differ.
[0016] Optionally, each of the bird spikes includes a first spike body, a spring, and a second spike body that are fixedly connected in sequence, with the first spike body connected to the surface of the hollow sphere.
[0017] By employing the above technical solution, this utility model has at least the following advantages:
[0018] Because the support rod is installed on the crossarm of the tower via bearings, the support rod can rotate relative to the crossarm. During the operation of the power line, at a certain moment, natural wind from the same direction impacts the convex surface of one hemispherical panel and the concave surface of the other hemispherical panel, causing the concave surface of the hemispherical panel to experience greater force. This causes the balance bar to drive the support rod to rotate, and the support rod drives the hollow ball and multiple bird spikes to rotate. Compared to the stationary bird spikes, this further deters birds perched on the crossarm of the tower.
[0019] At the same time, the rotation of the hollow ball and bird-proof spikes generates centrifugal force, which dispels debris and prevents debris from remaining in the gaps between multiple bird-proof spikes. This also prevents birds from placing branches in the gaps between adjacent bird-proof spikes, thus preventing the hollow ball and multiple bird-proof spikes from becoming the basis for birds to build nests.

[0022] The reference numerals in the accompanying drawings include: support rod 1, bearing 2, tower crossarm 3, hollow ball 4, bird spike 5, balance bar 6, hemispherical panel 7, rain cap 8, solid ball 9, U-shaped frame 10, bolt 11, first spike 501, spring 502, and second spike 503. Detailed Implementation
[0023] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.
[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0025] like Figure 1 As shown, an embodiment of this utility model provides a novel bird-proof device for power lines, which includes: a support rod 1, a bird-proof mechanism, and a drive mechanism;
[0026] The support rod 1 is mounted on the crossarm 3 of the tower via bearing 2;
[0027] The bird-proof mechanism includes a hollow ball 4 and multiple bird spikes 5. The hollow ball 4 is fixedly connected to the upper end of the support rod 1. The central axis of the support rod 1 coincides with the center of the hollow ball 4. The multiple bird spikes 5 are evenly distributed on the surface of the hollow ball 4.
[0028] The drive mechanism includes a balance bar 6 and two hemispherical panels 7. The center of the balance bar 6 is fixedly connected to the lower end of the support rod 1, and the edges of the two hemispherical panels 7 are respectively fixedly connected to the opposite ends of the balance bar 6. The two hemispherical panels 7 are symmetrical about the center of the support rod 1.
[0029] The working process of the new bird-proof device for power lines is as follows:
[0030] Because the support rod 1 is installed on the crossarm 3 of the tower via the bearing 2, the support rod 1 can rotate relative to the crossarm. During the operation of the power line, at a certain moment, the natural wind in the same direction impacts the convex surface of one hemispherical panel 7 and the concave surface of the other hemispherical panel 7, causing the concave surface of the hemispherical panel 7 to be subjected to greater force, which causes the balance bar 6 to drive the support rod 1 to rotate. The support rod 1 drives the hollow ball 4 and multiple bird spikes 5 to rotate, which, relative to the stationary bird spikes 5, further deters birds that are perched on the crossarm 3 of the tower.
[0031] At the same time, the rotation of the hollow ball 4 and the bird-proof spikes 5 generates centrifugal force, which dispels debris and prevents debris from remaining in the gaps between the multiple bird-proof spikes 5. This also prevents birds from placing branches in the gaps between adjacent bird-proof spikes 5, thus preventing the hollow ball 4 and the multiple bird-proof spikes 5 from becoming the basis for birds to build nests.
[0032] In the technical solution of this utility model, for a fixed bird-proof spike 5 device, the amount of nesting material that birds carry twigs to place on the bird-proof spike 5 shape increases, and the bird-proof spike 5 shape may become the foundation of a bird's nest. However, the bird-proof spike 5 shape of this application is rotatable, which avoids the possibility of birds building nests.
[0033] Specifically, the end of each bird spike 5 is fixedly connected to the surface of the hollow sphere 4, and the central axis of each bird spike 5 coincides with the center of the hollow sphere 4.
[0034] like Figure 1 As shown, specifically, the vertical plane where the balance bar 6 is located coincides with the plane where the edge of the hemispherical panel 7 is located, so that the natural wind in the horizontal direction can be applied to the concave surface of the hemispherical panel 7 as much as possible.
[0035] like Figure 2 As shown, in another embodiment, the balance bar 6 may also include three supports, one end of each support being connected to the edge of a hemispherical panel 7, and the other end being connected to the lower end of the support rod 1. The three hemispherical panels 7 are symmetrical about the lower end of the support rod 1.
[0036] Specifically, the outer surface of the hollow sphere 4 is polished and coated with an anti-rust coating so that the outer surface of the hollow sphere 4 can reflect sunlight for a long time. Together with the rotating bird spikes 5, it plays a better role in driving away birds.
[0037] In a specific embodiment, a rain cap 8 is also included, which is fixedly connected to the side of the support rod 1 between the hollow ball 4 and the bearing 2.
[0038] In this embodiment, specifically, the center of the rain cap 8 is fixedly connected to the support rod 1 between the hollow ball 4 and the bearing 2. The diameter of the rain cap 8 is larger than the diameter of the bearing 2. The rain cap 8 is inclined from its center to the edge, which has the function of guiding rainwater to the periphery of the bearing 2, avoiding the bearing 2 from being eroded by rainwater, and extending the mechanical working time of the bearing 2.
[0039] In a specific embodiment, a solid sphere 9 is also included, which is fixedly connected to the inner surface of the hollow sphere 4, and the horizontal plane of the solid sphere 9 coincides with the center of the hollow sphere 4.
[0040] In this embodiment, specifically, the horizontal plane where the solid ball 9 is located is perpendicular to the support rod 1. Therefore, during the rotation of the support rod 1, the solid ball 9 is driven to perform circular motion. Due to inertia, the circular motion of the solid ball 9 is not easy to stop, thereby prolonging the rotation time of the hollow ball 4.
[0041] In a specific embodiment, it also includes a U-shaped frame 10, the outer edge of which is fixedly connected to the outer ring of the bearing 2, the inner edge of which fits into the tower crossarm 3, and the side wall of the U-shaped frame 10 is provided with screw holes for threaded connection of bolts 11 so that the bolts 11 abut against the tower crossarm 3.
[0042] In this embodiment, specifically, when using this device, tightening the bolt 11 connects the tower crossarm 3, and the U-shaped frame 10 is installed on the tower crossarm 3; when disassembling this device, loosening the bolt 11 allows the U-shaped frame 10 to detach from the tower crossarm 3.
[0043] In a specific embodiment, the hollow sphere 4, the support rod 1, the balance rod 6, and the two hemispherical panels 7 are made of aluminum alloy.
[0044] In this embodiment, the aluminum alloy is lightweight and high-strength, and both the support rod 1 and the balance rod 6 adopt a hollow tube structure. After the hemispherical panel 7 is driven by a gust of wind, the balance rod 6, the support rod 1, and the hollow ball 4 can rotate for a longer period of time.
[0045] Specifically, the bird spike 5 is made of steel wire.
[0046] In specific embodiments, the lengths of the multiple bird spikes 5 are not exactly the same.
[0047] In this embodiment, specifically, the long bird spike 5 increases the protection radius, while the short bird spike 5 ensures the electrical distance of the transmission line while achieving the bird protection function.
[0048] In a specific embodiment, each of the bird spikes 5 includes a first spike 501, a spring 502, and a second spike 503 that are fixedly connected in sequence, with the first spike 501 connected to the surface of the hollow sphere 4.
[0049] In this embodiment, specifically, when the support rod 1 drives the hollow ball 4 to rotate, the spring 502 can bend to a certain extent, which increases the amplitude of the flicking at the end of the second spike 503, increases the probability of birds being frightened, and further helps to drive away birds.
[0050] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
