Description

Technical Field

[0001] This utility model belongs to the field of aviation obstacle ball technology, specifically relating to an aviation obstacle ball with a novel wire clamp structure. Background Technology

[0002] Aviation obstacle balls (also known as aviation marker balls) are visual warning devices installed on overhead power transmission cables (especially 220kV and above lines crossing rivers and valleys). They use high-contrast colors (such as orange and white) to alert low-flying aircraft to avoid them.

[0003] Traditional cable clamps use rigid clamps or fixed-diameter wire holes, which can only match cables of specific diameters (such as standard steel-cored aluminum stranded wire). Because aerial cables tend to sag due to their own weight, typical clamps provide a linear grip on both sides of the sphere, which is inconsistent with the cable's natural curvature. This results in uneven stress distribution along the entire cable. The clamped and fixed ends of the obstacle ball pose a potential risk of cable damage, especially in windy weather when the sphere sways, causing severe stress at both ends and increasing the risk of cable wear. Utility Model Content

[0004] The purpose of this invention is to provide a novel aviation obstacle ball with a wire clamp structure, which features the ability to adapt to the gravity deformation of the cable in the clamping direction, a combination of clamping and positioning with cable displacement, and a balanced stress distribution on the cable.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A novel type of aviation obstacle ball with a wire clamp structure includes a sphere and wire-passing holes on both sides of the sphere. A wire clamp is installed within each wire-passing hole. An upper clamping plate and a lower clamping plate are bolted together, and a through hole corresponding to the wire-passing hole is located between the two clamping plates. The upper clamping plate is composed of a positioning short plate and a displacement long plate. The positioning short plate is close to the wire-passing hole and connected to the lower clamping plate by a set of first bolts to clamp and position the cable. The displacement long plate is connected to the lower clamping plate by multiple sets of second bolts. The clamping length of the second bolts gradually increases in the direction away from the wire-passing hole, or the through hole gradually increases in the direction away from the wire-passing hole, to accommodate the gravitational deformation of the cable.

[0007] Additional technical features constituting the above-mentioned novel wire clamp structure of the aviation obstacle ball also include:

[0008] —A spring is fitted inside the bolt, and the length of the spring is in the same direction as the clamping length of the second bolt.

[0009] —The positioning short plate and the displacement long plate are connected by a hinge structure or by a flexible rope, and the end of the flexible rope is positioned by a screw or an anchor.

[0010] —The lower clamping plate has the same structure as the upper clamping plate;

[0011] —The sphere has a clamping arm extending from the threading hole, and the clamping arm is positioned between the upper clamping plate and the lower clamping plate;

[0012] —The inner side of the positioning short plate and / or the lower clamping plate has a folded plate that fits against the sphere, and a positioning plate corresponding to the folded plate is provided inside the sphere. The folded plate and the positioning plate are connected by a through third bolt.

[0013] Compared with the prior art, the novel wire clamp structure of this utility model for aviation obstacle balls has the following advantages: The upper clamping plate of this aviation obstacle ball wire clamp structure is composed of a positioning short plate and a displacement long plate spliced ​​together. The positioning short plate is close to the wire hole and is connected to the lower clamping plate by a set of first bolts to achieve clamping and positioning of the cable. The displacement long plate is connected to the lower clamping plate by multiple sets of second bolts. The clamping length of the second bolts gradually increases in the direction away from the wire hole, or the through hole gradually increases in the direction away from the wire hole. In this way, the clamping direction can be consistent with the arc formed by the downward sinking of the cable, so as to achieve stress balance on the cable. The obstacle ball is hung on the cable, rather than being positioned by clamping at both ends, avoiding the problem of strong local stress amplitude and severe wear on the cable, ensuring the safety and stability of the obstacle ball, and has the advantages of compact structure, convenient installation, economy and durability.

[0016] The novel wire clamp structure for aviation obstacle balls and its working principle provided by this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] In the description of this utility model, unless otherwise stated, the terms "inner / outer", "upper / lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "set / equipped" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figure 1 As shown, the novel wire clamp structure of the aviation obstacle ball includes a ball 1 and wire holes 2 on both sides of the ball 1. A wire clamp is installed in the wire hole 2. The upper clamp plate 31 and the lower clamp plate 32 are connected by bolts to the edge of the wire clamp. There is a through hole 30 between the two that corresponds to the wire hole 2. The upper clamp plate 31 is composed of a positioning short plate 41 and a displacement long plate 42 spliced ​​together. The positioning short plate 41 is close to the wire hole 2 and is connected to the lower clamp plate 32 by a set of first bolts 51 to clamp and position the cable a. The displacement long plate 42 is connected to the lower clamp plate 32 by multiple sets of second bolts 52. The clamping length of the second bolts 52 gradually increases in the direction away from the wire hole 2 or the through hole gradually increases in the direction away from the wire hole 2 to adapt to the gravity deformation of the cable a.

[0020] Its working principle is as follows: The ball 1 of the aviation obstacle ball has wire holes 2 on both sides. The cable a passes through the wire holes 2. The ball 1 and the cable are positioned by setting a wire clamp. The positioning short plate 41 of the upper clamp 31 is close to the wire hole 2 and is connected to the lower clamp 32 by a set of first bolts 51 to clamp and position the cable a. The displacement long plate 42 is connected to the lower clamp 32 by multiple sets of second bolts 52. The clamping length of the second bolts 52 gradually increases in the direction away from the wire hole 2 or the through hole gradually increases in the direction away from the wire hole 2. In this way, the clamping direction is coordinated with the arc formed by the weight of the cable, ensuring that the stress distribution on the cable is balanced and reducing the wear on the cable a.

[0021] In the aviation obstacle ball structure that constitutes the above-mentioned novel wire clamp structure

[0022] — Preferably, a spring 6 is installed inside the bolt. The length of the spring 6 is in the same direction as the clamping length of the second bolt 52. That is, the pre-tightening pressure of the spring 6 maintains the degree of connection between the displacement plate 42 and the cable, and improves the clamping force of the plate on the cable, thereby ensuring the stable positioning of the obstacle ball 1. The spring 6 can also be replaced by a rubber elastic pad.

[0023] — To enhance the integrity of the upper clamping plate 31 structure, the edges of the positioning short plate 41 and the displacement long plate 42 are connected by a hinge structure 7 or by a flexible rope. The end of the flexible rope is positioned by screws or anchors. That is, the positioning short plate 41 and the displacement long plate 42 are connected as one unit by the hinge structure 7 (such as a hinge) or the flexible rope (such as a steel strand) and can maintain relative movement to adapt to the arc-shaped change of the cable a due to gravity.

[0024] —Furthermore, the lower clamp 32 and the upper clamp 31 have the same structure, maintaining the symmetry of the clamp structure and adapting to various changes in the cable. For example, in windy weather, the clamp structure can adapt to the cable rising and forming an arc.

[0025] --like Figure 2 As shown, in order to improve the deep integration of the obstacle ball and the clamp structure, the ball 1 has a clamping arm 8 extending from the wire hole 2. The clamping arm 8 is placed between the upper clamping plate 31 and the lower clamping plate 32. Generally speaking, the ball 1 is formed by assembling two upper and lower spherical shells. The clamping arm 8 extends from the wire hole 2, that is, the wire hole 2 is extended. The clamping arm 8 is located in the through hole 30 between the upper clamping plate 31 and the lower clamping plate 32. The two sides are then positioned by bolts (51, 52).

[0026] —The inner side of the aforementioned positioning short plate 41 and / or lower clamping plate 32 has a fold 91 that fits against the ball 1. A positioning plate 92 corresponding to the fold 91 is provided inside the ball 1. The fold 91 and the positioning plate 92 are connected by a through third bolt 53, which further enhances the assembly structure of the wire clamp and the ball 1 and facilitates use, installation, disassembly and maintenance.

[0027] The above-described embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit the implementation of this utility model. Therefore, any other modifications or equivalent substitutions to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
