Description

Technical Field

[0001] This invention relates to the field of aviation obstacle warning devices, and more particularly to a low-noise aviation warning ball mounting structure. Background Technology

[0002] To ensure the safety of aircraft during low-altitude flight and to improve the visibility of high-altitude obstacles, aviation warning balls, as an important visual safety device, are widely installed on high-voltage overhead power lines, communication lines, and other overhead facilities near airports that may pose a threat to flight safety.

[0003] However, some existing aviation warning domes still have shortcomings in structural design and installation methods, especially during long-term service or under extreme weather conditions. Common problems include: the dome is composed of two hemispheres joined together, but the edge connections are not securely restrained; uneven stress during installation causes deformation of the dome; or cracks or gaps appear at the edges of the dome due to material aging, weathering, thermal expansion and contraction. These factors can all create tiny gaps between the two hemispheres at the connection point. When subjected to external loads (such as wind loads or ground wire vibrations), if the edge connections between the two hemispheres lack sufficient restraint and buffering, they are very likely to collide frequently during vibration, resulting in continuous structural noise. This seriously affects the normal lives of residents near the power lines.

[0004] Therefore, there is an urgent need to provide an aviation warning ball with a more stable structure and good vibration reduction and noise reduction effect, so as to solve the noise problem caused by structural loosening or collision of joints during high-altitude operation of existing products, thereby improving the environmental friendliness and reliability of the product. Summary of the Invention

[0005] This invention provides a low-noise aviation warning ball mounting structure, which can solve the problem that existing aviation warning balls are prone to structural noise under external forces such as wind load or conductor vibration.

[0006] Embodiments of the present invention provide a low-noise aviation warning dome mounting structure, including a hollow sphere, a buffer pad, and a mounting bracket. The hollow sphere includes a first hollow hemisphere, a second hollow hemisphere, and a connector. The edge of the second hollow hemisphere abuts against the edge of the first hemisphere, and the connector securely connects the first and second hollow hemispheres. The buffer pad is made of an elastic material and is sandwiched between the edges of the first and second hollow hemispheres. The mounting bracket mounts the hollow sphere onto a ground wire.

[0007] In some embodiments, there are multiple buffer pads, each buffer pad has an arc-shaped structure, and the center line of each buffer pad coincides with the center line of the first hollow hemisphere and the second hollow hemisphere. Each buffer pad is arranged around the center line of the first hollow hemisphere and the second hollow hemisphere.

[0008] In some embodiments, the connector includes a plurality of first bolts, each first bolt arranged around the center line of a first hollow hemisphere and a second hollow hemisphere, and fixing the edge of the first hollow hemisphere to the edge of the second hollow hemisphere. Each buffer pad has a first bolt hole through which the first bolt passes.

[0009] In some embodiments, the mounting bracket includes a first mounting block, a second bolt, and a second mounting block. The first mounting block has a first arcuate surface that conforms to the outer wall of the hollow sphere. The second bolt secures the first mounting block to the wall of the hollow sphere. The second mounting block is connected to the first mounting block and has a grounding channel for a ground wire to pass through.

[0010] In some embodiments, the second mounting block includes a first mounting plate, a second mounting plate, and a third bolt. The first mounting plate has a first groove. The second mounting plate has a second groove, the edge of which abuts against the edge of the first groove to form a grounding channel. The third bolt securely connects the first mounting plate and the second mounting plate.

[0011] In some embodiments, the low-noise aviation warning ball mounting structure further includes an internal support. The internal support is disposed within the hollow sphere and includes a mounting base having a second arc surface that fits against the inner wall of the hollow sphere. The mounting base also has a second bolt hole for a second bolt to pass through.

[0012] In some embodiments, the inner support further includes multiple support limbs, each of which is an arc-shaped structure and fits against the inner wall of the hollow sphere. The first end of each support limb is connected to the mounting base.

[0013] In some embodiments, there are multiple cushioning pads, each arranged around the centerline of the first and second hollow hemispheres. The inner support also includes multiple fixing plates, each fixed plate being connected to the second end of each support limb. Each fixing plate is sandwiched between the edge of the first hollow hemisphere and the edge of the second hollow hemisphere, and is respectively filled between two adjacent cushioning pads.

[0014] In some embodiments, the connector includes a plurality of first bolts, each first bolt arranged around the center line of a first hollow hemisphere and a second hollow hemisphere, and fixing the edge of the first hollow hemisphere to the edge of the second hollow hemisphere. Each fixing plate has a third bolt hole through which the first bolts pass.

[0015] In some embodiments, the low-noise aviation warning ball mounting structure also includes a pre-stretched protective line and equalizing rings. The pre-stretched protective line wraps around the ground wire. The equalizing rings are located at both ends of the pre-stretched protective line.

[0016] According to an embodiment of the present invention, a low-noise aviation warning sphere mounting structure is provided, in which the ground wire no longer passes through the interior of the aviation warning sphere, but is instead suspended via a mounting bracket located on the exterior of the sphere, thus avoiding structural interference and sphere deformation caused by the ground wire passing through the sphere. The structure of the present invention effectively mitigates the relative movement and impact between the two hemispheres by introducing a buffer pad at the edge of the sphere joint, effectively suppressing impact and vibration noise at the joint, significantly reducing structural noise caused by wind vibration, and improving the environmental friendliness and stability of the equipment operation.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] See Figures 1-6 The present invention provides a low-noise aviation warning ball mounting structure, including a hollow ball 1, a buffer pad 2, a mounting bracket 3, an inner support 4, a pre-twisted protective line 5, and an equalizing ring 6.

[0021] The hollow sphere 1, also known as a low-noise aviation warning sphere, is used to improve the aerial visibility of power transmission lines and effectively prevent aircraft from colliding with the overhead ground wire 7. The hollow sphere 1 includes a first hollow hemisphere 11, a second hollow hemisphere 12, and connecting parts.

[0022] The opening of the first hollow hemisphere 11 faces downwards, with its edge located at its bottom. The first hollow hemisphere 11 serves as the upper part of the aviation warning ball, also referred to as the upper hemisphere. The first hollow hemisphere 11 is made of high-strength polycarbonate or fiberglass, possessing excellent weather resistance and impact resistance, enabling it to adapt to long-term outdoor use and extending the service life of the aviation warning ball.

[0023] The opening of the second hollow hemisphere 12 faces upwards, with its edge positioned at its top. The second hollow hemisphere 12 serves as the lower half of the aviation warning sphere, also referred to as the lower hemisphere. The edge of the second hollow hemisphere 12 aligns with the edge of the first hollow hemisphere 11. The second hollow hemisphere 12 is made of high-strength polycarbonate or fiberglass, possessing excellent weather resistance and impact resistance, enabling it to withstand long-term outdoor use and extending the service life of the aviation warning sphere. The bottom of the second hollow hemisphere 12 has at least one drainage hole 121, such as one or two, for draining accumulated water from inside the sphere.

[0024] A connector securely connects the first hollow hemisphere 11 to the second hollow hemisphere 12. The connector includes multiple first bolts 13, each arranged around the centerline of the first and second hollow hemispheres 11 and 12, and securing the edges of the first and second hollow hemispheres 11 and 12. For this purpose, the edge of the first hollow hemisphere 11 has multiple first connecting screw holes 111, the centerlines of which are parallel to the centerline of the first hollow hemisphere 11, and the first connecting screw holes 111 are arranged around the centerline of the first hollow hemisphere 11. The edge of the second hollow hemisphere 12 has multiple second connecting screw holes 122, each aligned with a first connecting screw hole 111, forming multiple sets of connecting screw holes. Each first bolt 13 passes through each set of connecting screw holes and is locked with a nut, thus securing the edges of the first and second hollow hemispheres 11 and 122 together.

[0025] The buffer pad 2 provides effective cushioning and damping for the contact between the two hemispheres under wind-induced vibration or mechanical impact, reducing the transmission of structural vibration and noise. The buffer pad 2 is made of an elastic material, specifically rubber, silicone, or polyurethane foam, which possess elasticity and vibration-damping properties. The buffer pad 2 is sandwiched between the edges of the first hollow hemisphere 11 and the second hollow hemisphere 12, maintaining a durable cushioning and vibration isolation effect during repeated wind-induced vibrations. There can be one buffer pad 2, which is a ring-shaped structure with its centerline coinciding with the centerlines of the first and second hollow hemispheres 11 and 12. Alternatively, there can be multiple buffer pads 2, each with an arc-shaped structure and its centerline coinciding with the centerlines of the first and second hollow hemispheres 11 and 12, arranged around their centerlines to enhance adaptability and vibration absorption during installation. Adjacent buffer pads 2 can be installed flush against each other or spaced apart. Each buffer pad 2 has at least one first bolt hole 21, such as one or two, and each first bolt hole 21 is for each first bolt 13 to pass through, so that the two hemispheres and the buffer pad 2 are reliably fastened by bolts to form a sphere with a stable overall structure.

[0026] Mounting bracket 3 mounts the hollow sphere 1 onto the ground wire 7, effectively suspending the hollow sphere 1 from the ground wire 7. This design avoids the structural interference and stress concentration problems caused by the ground wire 7 passing through the interior of the sphere in traditional structures, thus improving the sphere's resistance to deformation and ease of installation. Mounting bracket 3 is made of lightweight metal. Mounting bracket 3 includes a first mounting block 31, a second bolt 32, and a second mounting block 33.

[0027] The first mounting block 31 has a first arc surface, which is in contact with the outer wall of the hollow sphere 1, such as the first arc surface being in contact with the top of the outer wall of the first hollow hemisphere 11.

[0028] The second bolt 32 securely connects the first mounting block 31 to the wall of the hollow sphere 1, such as securing the first mounting block 31 to the top of the wall of the first hollow hemisphere 11. For this purpose, the first mounting block 31 has multiple third connecting screw holes 311, each located at one of the four corners of the first mounting block 31. The top of the wall of the first hollow hemisphere 11 has multiple fourth connecting screw holes 112, each aligned with a third connecting screw hole 311, forming multiple sets of connecting screw holes. Multiple second bolts 32 are used, each passing through one of the multiple sets of connecting screw holes and locked with a nut, thus securing the first mounting block 31 to the wall of the hollow sphere 1.

[0029] The second mounting block 33 is located below the first mounting block 31. The second mounting block 33 is connected to the first mounting block 31 and has a ground wire channel 331 through which the ground wire 7 passes. The second mounting block 33 includes a first mounting plate 332, a second mounting plate 333, and a third bolt 334. The first mounting plate 332 has a first groove. The second mounting plate 333 is located below the first mounting plate 332. The second mounting plate 333 has a second groove, the edge of which abuts against the edge of the first groove to form the ground wire channel 331. The third bolt 334 securely connects the first mounting plate 332 and the second mounting plate 333. For this purpose, the first mounting plate 332 has multiple fifth connecting screw holes 3321, each fifth connecting screw hole 3321 located on both sides of the first groove. The second mounting plate 333 has multiple sixth connecting screw holes (not shown in the figure), each sixth connecting screw hole aligned with each fifth connecting screw hole 3321, forming multiple sets of connecting screw holes. There are multiple third bolts 334, each of which passes through multiple sets of connecting screw holes and is locked with nuts to fix the first mounting plate 332 and the second mounting plate 333.

[0030] The inner support 4 is used to enhance the structural strength and load-bearing capacity of the sphere. The inner support 4 is installed inside the hollow sphere 1, such as inside the first hollow hemisphere 11. The inner support 4 includes a mounting base 41, a support limb 42, and a fixing plate 43.

[0031] The mounting base 41 has a second arc surface that fits against the inner wall of the hollow sphere 1, such as the second arc surface fitting against the top of the inner wall of the first hollow hemisphere 11. The mounting base 41 has multiple second bolt holes 411, each for a second bolt 32 to pass through, so that the first mounting block 31 is secured to the wall of the hollow sphere 1 and the mounting base 41 by bolts, ensuring connection strength and uniform load transfer, and fixing the inner support 4 inside the hollow sphere 1 by bolts.

[0032] The number of support limbs 42 is multiple, such as four or more. Each support limb 42 is an arc-shaped structure and is fitted to the inner wall of the hollow sphere 1, such as the inner wall of the first hollow hemisphere 11. The first end of each support limb 42 is connected to the mounting base 41. By using several inner support limbs and a mounting base 41, the stress-bearing area of ​​the sphere is increased, enhancing the stress stability of the sphere at the mounting location and improving the seismic performance and load distribution capacity of the overall structure.

[0033] There are multiple fixing plates 43, each of which is connected to the second end of each support limb 42. Each fixing plate 43 is sandwiched between the edge of the first hollow hemisphere 11 and the edge of the second hollow hemisphere 12, and is filled between two adjacent buffer pads 2. Each fixing plate 43 has a third bolt hole 431 through which a first bolt 13 passes, for fixing the fixing plate 43 with bolts, thereby enhancing the connection strength and assembly accuracy, and effectively suppressing the relative movement and impact generated at the joint of the spheres under wind-induced vibration or structural excitation, thus playing a noise reduction role.

[0034] Pre-stranded protective strip 5 is wrapped around the ground wire 7. Based on the diameter of the ground wire 7 and the size of the ground wire channel 331, a pre-stranded protective strip 5 of matching diameter is selected to wrap around the ground wire 7 to prevent the ground wire 7 from being damaged or scratched during the fixing process, and to enhance the mechanical stability between the mounting bracket 3 and the ground wire 7.

[0035] The equalizing ring 6 is set at both ends of the pre-stretched protective line 5 to improve the electric field distribution at the end of the protective line, reduce the corona discharge phenomenon caused by the concentration of electric field intensity, and thus effectively suppress corona noise.

[0036] An embodiment of the present invention also provides an installation method for the above-mentioned low-noise aviation warning ball mounting structure, comprising the following steps: (1) The first hollow hemisphere 11, the first mounting block 31, and the mounting base 41 are fixedly connected by the second bolt 32.

[0037] In the above steps, the mounting base 41 is placed inside the first hollow hemisphere 11, and then the fourth connecting screw hole 112 of the first hollow hemisphere 11, the third connecting screw hole 311 of the first mounting block 31, and the second bolt hole 411 of the mounting base 41 are aligned. The three are then fastened with the second bolt 32, thereby fixing the first hollow hemisphere 11, the first mounting block 31, and the mounting base 41 together with the second bolt 32.

[0038] (2) The first hollow hemisphere 11, the second hollow hemisphere 12, the buffer pad 2 and the fixing plate 43 are fixedly connected by the first bolt 13.

[0039] In the above steps, the buffer pad 2 is sandwiched between the edge of the first hollow hemisphere 11 and the edge of the second hollow hemisphere 12. Then, the first connecting screw hole 111 of the first hollow hemisphere 11, the second connecting screw hole 122 of the second hollow hemisphere 12, and the first bolt hole 21 of the buffer pad 2 are aligned and fastened with the first bolt 13. Then, the fixing plate 43 is sandwiched between the edge of the first hollow hemisphere 11 and the edge of the second hollow hemisphere 12 and filled between two adjacent buffer pads 2. The first connecting screw hole 111 of the first hollow hemisphere 11, the second connecting screw hole 122 of the second hollow hemisphere 12, and the third bolt hole 431 of the fixing plate 43 are aligned and fastened with the first bolt 13. This achieves the fixed connection of the first hollow hemisphere 11, the second hollow hemisphere 12, the buffer pad 2, and the fixing plate 43 by the first bolt 13.

[0040] (3) Wrap the pre-twisted protective line 5 around the installation position of the ground wire 7.

[0041] (4) Place the installation position of the ground wire 7 in the ground wire channel 331.

[0042] In the above steps, after the ground wire 7 is placed in the first groove of the first mounting plate 332 and the second groove of the second mounting plate 333, the fifth connecting screw hole 3321 of the first mounting plate 332 and the sixth mounting screw hole of the fourth mounting plate are aligned, and the two are fastened by the third bolt 334, so that the position to be installed of the ground wire 7 is placed in the ground wire channel 331, thereby firmly installing the hollow sphere 1 on the ground wire 7.

[0043] (5) Install equalizing rings 6 at both ends of the pre-stretched protective line 5.

[0044] The above steps can be omitted. When there is a significant corona discharge phenomenon in the transmission line, or when the diameter of the selected pre-stretched protective wire 5 is small, this step can be implemented according to the actual operating electric field conditions to improve the electric field shielding and electrical protection effect of the ground wire 7.

[0045] The present invention has the following beneficial effects: (1) The ground wire 7 no longer passes through the inside of the aviation warning ball, but is suspended by the mounting bracket 3 set on the outside of the ball, thus avoiding structural interference and deformation of the ball caused by the ground wire 7 passing through the ball.

[0046] (2) By introducing a buffer pad 2 at the edge of the sphere splicing, the relative motion and impact between the two hemispheres can be effectively alleviated, and the structural noise caused by wind vibration can be significantly reduced.

[0047] (3) Optimize the structure and connection method of the mounting bracket 3 to improve the stability and wind resistance of the sphere installation.

[0048] (4) Set screw holes at the joint of the two hemispheres and use bolts to fix them, so as to achieve multi-point locking, limit micro-movement, and avoid repeated impact due to structural gaps.

[0049] (5) Set up inner support 4 to effectively enhance the force distribution and deformation resistance of the inner side of the sphere, and form a highly stable support system in conjunction with the external support.

[0050] (6) The selected materials have good weather resistance and vibration reduction performance, which improves the stability and service life of the equipment. The installation method is simple, the components are highly modular, and it is suitable for various overhead transmission lines and places with high visibility requirements, and has a wide range of engineering application value.

[0051] (7) Additionally, a mounting bracket 3 is added to prevent the aviation warning ball from directly contacting the ground wire, thus avoiding the impact of ground wire vibration on the aviation warning ball.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
