Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to vibration damping spacers. Background Technology

[0002] Spacer bars are key devices used in power transmission line engineering to isolate vibrations between split cables. Their core functions include: maintaining cable spacing to meet safety electrical clearance requirements, suppressing cable vibrations caused by wind (such as light wind vibrations), and reducing cable fatigue damage to ensure long-term line stability. Especially in complex natural environments (such as high altitudes, strong coastal winds, and mountainous terrain) and with diverse cable arrangements (such as horizontal splitting, vertical splitting, and umbrella-shaped arrangements), spacer bars significantly reduce the risk of short circuits, line breaks, and other faults caused by vibration by limiting relative cable displacement and dissipating vibration energy. They play an irreplaceable role in improving the reliability of power transmission systems and extending cable lifespan.

[0003] Traditional spacers typically employ a rigid connection structure, dissipating energy through friction between cables or localized elastic deformation. However, in practical applications, it has been found that under continuous wind force, undissipated vibration energy can easily accumulate, leading to cable fatigue fracture or spacer body cracking. This fails to achieve the intended vibration damping purpose and increases the safety risks to transmission lines. Utility Model Content

Simultaneously, by forming a damping chamber inside the elastic damping ring, the cable located inside the damping chamber is tightly wrapped by the elastic damping ring, restricting its lateral or longitudinal displacement. Furthermore, the buffering properties of the elastic material can alleviate the phenomenon of instantaneous stress concentration caused by wind, temperature changes, or external impacts, reducing the risk of cable wear and fatigue fracture due to vibration.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0028] According to an embodiment of the present invention, a vibration damping spacer is provided, including a fixing mechanism 1.

[0029] like Figure 1 , Figure 4 and Figure 5 As shown, the device includes a fixed locking clip 11, a fixed base 12, and an elastic damping ring 13. One end of the fixed locking clip 11 along its length is rotatably connected to the fixed base 12 via a first rotating shaft 14. The other end of the fixed locking clip 11 along its length is detachably connected to the fixed base 12 via a fastener. When the other end of the fixed locking clip 11 along its length is connected to the fixed base 12 via a fastener, the two inner wall surfaces of the fixed locking clip 11 and the fixed base 12, which are arranged close to each other, enclose a receiving chamber. The outer wall of the elastic damping ring 13 is conformally arranged to the inner wall of the receiving chamber. The elastic damping ring 13 is used to be installed inside the receiving chamber. The inner wall of the elastic damping ring 13 encloses a damping chamber 131 for placing cables.

[0030] With this configuration, by setting a fixed locking clip 11 and a fixed base 12, and with one end of the fixed locking clip 11 rotatably connected to the fixed base 12 via a first rotating shaft 14, and the other end detachably connected to the fixed base 12 via a fastener, the fixed locking clip 11 is allowed to adjust the opening size of the receiving chamber during installation, which helps to accommodate cables of different sizes without the need for complicated operating tools.

[0031] Meanwhile, by forming a damping chamber 131 inside the elastic damping ring 13, the cable located inside the damping chamber 131 will be tightly wrapped by the elastic damping ring 13, restricting its lateral or longitudinal displacement.

[0032] In addition, the elastic material has cushioning properties, which can alleviate the degree of instantaneous stress concentration caused by wind, temperature changes or external impacts, and reduce the risk of cable wear and fatigue fracture caused by vibration.

[0033] It can be noted that the internal damping chamber 131 of the elastic damping ring 13 is preferably cylindrical.

[0034] It can be explained that the length direction of the fixed locking clip 11 is defined as the direction in which one of the rotating part and the detachable connection part of the fixed locking clip 11 extends to the other.

[0035] Furthermore, when the elastic damping ring 13 is not installed, it has a long strip structure. When installed, its two free ends along its length are respectively bonded and fixed to the inner wall of the receiving chamber formed by the fixing lock 11 and the fixing base 12. When the other end of the fixing lock 11 along its length is connected to the fixing base 12 by fasteners, the two free ends are connected end to end and enclose to form a cylindrical damping chamber 131.

[0036] It can be noted that there is no specific limitation on the way the other end of the fixing lock 11 is detachably connected to the fixing base 12 by fasteners.

[0037] Preferably, the fixing lock 11 has a countersunk hole, the fixing base 12 has a threaded hole, and the fastener is preferably a bolt. During installation, the bolt stud is inserted through the countersunk hole and then gradually screwed into the threaded hole until it is tightened. After installation, the bolt head is located in the countersunk hole.

[0038] like Figures 1 to 3 As shown, in one embodiment, the vibration damping bar further includes a soft steel damping mechanism 2, which includes an energy-dissipating ring 21; the fixed base 12 is rotatably connected to the energy-dissipating ring 21 via a second rotating shaft 22.

[0039] With this configuration, by adding a soft steel damping mechanism 2, such as an energy-dissipating ring 21, and combining it with an elastic damping ring 13, multiple energy dissipation mechanisms are formed. That is, vibration energy is dissipated through elastic, plastic, and frictional energy dissipation processes. At the same time, the fixed base 12 is rotatably connected to the energy-dissipating ring 21 using a second rotating shaft 22, allowing the fixed base 12 to rotate relative to the energy-dissipating ring 21 during vibration. This avoids energy concentration due to rigid connection in one direction and improves the adaptability of the vibration-damping spacer to complex vibration environments.

[0040] like Figures 1 to 5As shown, in one embodiment, the end face of the energy-consuming ring 21 close to the fixed base 12 along the axial direction is the first contact surface 211; the fixing mechanism 1 also includes a connector 15, which is installed on the fixed base 12, and the end face of the connector 15 close to the energy-consuming ring 21 along the axial direction is the second contact surface 151, which is used to contact the first contact surface 211.

[0041] With this configuration, by providing a first contact surface 211 and a second contact surface 151 and making the two contact surfaces in direct contact, vibration energy is dissipated through friction, thereby further enhancing the vibration-damping spacer's ability to resist vibration.

[0042] It can be explained that the energy-consuming ring 21 includes a columnar protrusion and an arc-shaped rod. When the columnar protrusion and the arc-shaped rod are connected, the energy-consuming ring 21 is circular or nearly circular in shape.

[0043] Preferably, the axial direction of the columnar protrusion is parallel to the axial direction of the energy-consuming ring 21, and the end face of the columnar protrusion axially close to the fixed base 12 is the first contact surface 211.

[0044] Preferably, the columnar protrusion is a cylindrical protrusion, in which case the first contact surface 211 and the second contact surface 151 are a pair of circular contact surfaces.

[0045] Furthermore, the number of columnar protrusions and the number of arc-shaped rods are consistent with the number of fixed bases 12.

[0046] It can be noted that both the first contact surface 211 and the second contact surface 151 are ground and deburred. At this time, the end face of the connector 15 facing away from the energy dissipation ring 21 along the axial direction of the energy dissipation ring 21 is not ground or only lightly ground and deburred, thus reducing costs.

[0047] It can be explained that by adding an elastic structure, the second contact surface 151 is always in contact with the first contact surface 211.

[0048] As one implementation method, such as Figure 1 and Figure 5 As shown, the fixed base 12 is provided with a connecting part; the fixing mechanism 1 also includes a return spring 16, which is installed on the connecting part, and the elastic deformation direction of the return spring 16 is arranged along the axial direction of the energy dissipation ring 21; the connecting member 15 elastically abuts against the return spring 16.

[0049] With this configuration, a return spring 16 is provided, and the elastic deformation direction of the return spring 16 is set along the axial direction of the energy dissipation ring 21. The connector 15 is elastically abutted against the return spring 16, so that it can absorb the axial impact force between the connector 15 and the energy dissipation ring 21. The compression and rebound process of the spring ensures that the two contact surfaces always remain in close contact, avoiding the gap caused by the separation of the two contact surfaces due to vibration.

[0050] Meanwhile, the axial force applied by the return spring 16 can ensure that the two contact surfaces remain pressed together after frictional wear, and continue to play an energy-dissipating role.

[0051] Preferably, such as Figure 1 , Figures 4 to 6 As shown, in one embodiment, the connecting part includes a connecting hole 121. The toothed groove 122 of the connecting hole 121 extends from the end face of the fixed base 12 near the energy-dissipating ring 21 to the interior of the fixed base 12. The inner wall of the connecting hole 121 is provided with a plurality of toothed grooves 122 arranged in a circumferential array. The connecting member 15 is provided with a plurality of toothed protrusions 152 arranged in a circumferential array. The toothed protrusions 152 of the connecting member 15 are circumferentially limited and axially movable in the toothed groove 122.

[0052] With this configuration, the toothed protrusions 152 and toothed grooves 122 ensure that the connector 15 is precisely positioned in the circumferential direction after being installed in the connecting hole 121, preventing it from rotating relative to the fixed base 12, that is, avoiding rotation caused by vibration of the connector 15.

[0053] Meanwhile, when vibration generates axial force, the toothed protrusion 152 can move within the toothed groove 122, forming a buffering and recovery cycle energy dissipation mechanism with the return spring 16, thus achieving continuous energy dissipation.

[0054] In addition, by providing multiple toothed grooves 122 and multiple toothed protrusions 152, multi-point contact is formed, which avoids local stress concentration and reduces the risk of cracking or deformation of individual toothed protrusions 152 and toothed grooves 122.

[0055] Preferably, the connecting hole 121 is a circular hole, and the axis of the connecting hole 121 is parallel to the axis of the energy-consuming ring 21.

[0056] Furthermore, such as Figure 1 , Figures 4 to 6As shown, in one embodiment, the connecting part further includes a positioning hole 123, which is located on the side of the connecting hole 121 away from the energy-dissipating ring 21 along the axial direction of the connecting hole 121; the fixing mechanism 1 further includes a positioning ring 17, which is installed in the positioning hole 123; a return spring 16 is installed in the positioning hole 123, and is sleeved on the outside of the positioning ring 17 along the radial direction; wherein, the positioning ring 17, the positioning hole 123, and the return spring 16 are coaxial.

[0057] This configuration, by adding a positioning hole 123 and a positioning ring 17, and making the positioning hole 123, positioning ring 17 and return spring 16 coaxial, provides a precise guide path for the elastic deformation of return spring 16, restricts the degree of freedom of return spring 16 in the radial direction, ensures that return spring 16 is compressed or rebounds, avoids fatigue damage caused by radial displacement of return spring 16 during deformation, and extends its service life.

[0058] It can be noted that the number of connecting parts is the same as the number of fixed bases 12.

[0059] The connecting part is provided with two connecting holes 121. In the axial direction, the two connecting holes 121 are spaced apart, and the positioning ring 17 is located between the two connecting holes 121.

[0060] Furthermore, there are two connectors 15 in one connecting part, which are respectively installed in two connecting holes 121.

[0061] In use, the two ends of the return spring 16, which are arranged along its elastic deformation direction, respectively abut against the end faces of the two connecting pieces 15 that are away from the energy dissipation ring 21 along the axial direction of the energy dissipation ring 21.

[0062] The movement process is as follows: when an external force acts directly or indirectly on at least one columnar protrusion, it will transfer energy to the connector 15, and then, after passing through the first contact surface 211 and the second contact surface 151, it will transfer energy to the return spring 16. At this time, the axial distance between the two connectors 15 increases or decreases. During this period, the return spring 16 stores energy. After the external force disappears, the return spring 16 releases energy and drives the connector 15, which moved during the energy storage period of the return spring 16, to gradually return to its initial position.

[0063] It can be explained that, in order to further improve the effect of consuming vibrational energy, such as Figure 1 As shown, in one embodiment, there are two energy-consuming rings 21, which are coaxial and spaced apart on both sides of the fixed base 12.

[0064] With this configuration, by providing two energy-dissipating rings 21 and placing them at intervals on both sides of the fixed base 12, after installation, the energy-dissipating rings 21 on both sides can simultaneously absorb the vibration energy of the cable on both axial sides (such as bidirectional bending vibration of the cable caused by wind or temperature changes), thus improving the phenomenon of local overload or insufficient energy dissipation caused by the single-sided energy-dissipating ring 21 vibrating in a single direction.

[0065] Furthermore, with the fixed base 12 as the center of symmetry, the two energy-consuming rings 21 are symmetrically arranged, and the number of columnar protrusions on the two energy-consuming rings 21 is the same, and their positions correspond.

[0066] This symmetrical arrangement ensures that the fixed base 12 is subjected to uniform force, avoiding structural displacement or torsional vibration caused by energy dissipation on one side, reducing additional stress caused by asymmetrical loads, and improving structural durability.

[0067] It can be explained that there are multiple fixed bases 12, and the multiple fixed bases 12 are arranged in a circular array around the energy dissipation ring 21; the fixed locking clips 11 are arranged one-to-one with the fixed bases 12; and the elastic damping rings 13 are arranged one-to-one with the fixed bases 12.

[0068] This configuration, with multiple fixed bases 12 and fixed locking clips 11 and elastic damping rings 13 corresponding to the fixed bases 12, facilitates the simultaneous clamping and separation of multiple cables, thus broadening the applicability of the vibration damping spacer.

[0069] Similarly, the number of positioning rings 17 is the same as the number of fixed bases 12.

[0070] Furthermore, the ratio of the number of connecting holes 121 to the number of fixed bases 12 is two to one, and the ratio of the number of connectors 15 to the number of fixed bases 12 is two to one.

[0071] Preferably, such as Figure 1 As shown, one energy-consuming ring 21 corresponds to four fixed bases 12, and the four fixed bases 12 are arranged in a circular array around the circumference of the energy-consuming ring 21.

[0072] like Figures 1 to 3 As shown, in one embodiment, the soft steel damping mechanism 2 further includes a stiffening arc rod 23, the two opposite ends of which are connected to the inner wall of the energy dissipation ring 21, and the stiffening arc rod 23 forms an arc-shaped protrusion toward the center of the energy dissipation ring 21.

[0073] With this configuration, by adding stiffening arc rods 23, during installation, both opposite ends of the stiffening arc rods 23 are connected to the inner wall of the energy-dissipating ring 21. The stiffening arc rods 23 are then convex in an arc shape toward the center of the energy-dissipating ring 21. When subjected to external loads, the energy-dissipating ring 21 is stretched into an ellipse under tension. The stiffening arc rods 23 in the tension direction are gradually straightened, while those in the compression direction are gradually bent. After unloading and reloading to a certain value, the elliptical ring gradually returns to a circular ring. The straightened stiffening arc rods 23 and the compressed stiffening arc rods 23 return to their original shapes. During the deformation and recovery process of the stiffening arc rods 23 and the energy-dissipating ring 21, vibration energy can be further dissipated, making it suitable for complex vibration environments.

[0074] Meanwhile, since the deformation and recovery process is continuous and cyclical, the plastic deformation and failure (failure-degradation-failure) process of the stiffening arc bar 23 is continuous. Therefore, by providing the stiffening arc bar 23, the soft steel damping mechanism 2 has the ability to dissipate energy through plastic hysteresis, thereby improving the service life of the soft steel damping mechanism 2.

[0075] It can be noted that the number of stiffening arc bars 23 can be two, four or more.

[0076] Preferably, each energy-consuming ring 21 has four stiffening arc rods 23 on its inner wall.

[0077] Still Figures 1 to 3 As shown, in one embodiment, the energy-dissipating ring 21 has at least one vibration damping groove 212 on each of its two axially opposite end faces, and the vibration damping grooves 212 on the two end faces are arranged one-to-one along the axial direction of the energy-dissipating ring 21.

[0078] With this configuration, damping grooves 212 are provided on both end faces of the energy-dissipating ring 21 that are opposite to each other along its axial direction. The damping grooves 212 serve as a pre-set weak area, so that the area where the energy-dissipating ring 21 preferentially undergoes plastic deformation (such as bending, shearing, or tension) when subjected to vibration load is the damping groove 212. That is, by forming the damping grooves 212, local weakening is achieved, so that when the energy-dissipating ring 21 yields, the yield surface is transferred to the weakened part, effectively reducing the stress concentration at the connection between the energy-dissipating ring 21 and the fixed base 12, and avoiding the energy concentration at the connection between the energy-dissipating ring 21 and the fixed base 12, which would cause the energy-dissipating ring 21 to fail prematurely.

[0079] Preferably, each energy-consuming ring 21 is provided with four sets of vibration damping grooves 212, and each set of vibration damping grooves 212 has two grooves. Along the axial direction of the energy-consuming ring 21, the two vibration damping grooves 212 in each set correspond to each other and are respectively opened on the two end faces of the energy-consuming ring 21.

[0080] It should be noted that the vibration damping spacer can be used in situations with different wind intensities.

[0081] For example, when a light breeze acts on the vibration damping spacer, the cable vibration energy is absorbed and consumed by the elastic damping ring 13.

[0082] For example, when a light wind (low wind intensity) acts on the vibration damping spacer, while the elastic damping ring 13 absorbs vibration energy, the cable vibration also causes the fixing mechanism 1 to rotate around the first rotating shaft 14. At this time, the vibration energy is further dissipated through the first contact surface 211 and the second contact surface 151. Simultaneously, the return spring 16 deforms axially within the connecting hole 121, and after frictional wear occurs on the first contact surface 211 and the second contact surface 151, the return spring 16 applies a pressing force between the two contact surfaces, allowing the two contact surfaces to continuously dissipate energy.

[0083] Of course, when a large wind force acts on the vibration damping spacer, while the elastic damping ring 13 absorbs the vibration energy and the two contact surfaces dissipate the vibration energy through friction, the cable vibration will also transfer the energy to the soft steel damping mechanism 2 through the fixing mechanism 1. At this time, the stiffening arc rod 23 will first deform to consume the energy. After the stiffening arc rod 23 deforms to a certain limit, due to the small thickness of the damping groove 212, plastic deformation will occur at the damping groove 212, thereby further consuming the vibration energy.

[0084] It should be noted that the energy-dissipating ring 21 and the stiffening arc rod 23 are integrally formed. If the energy-dissipating ring 21 is damaged, such as if the vibration damping groove 212 is damaged due to high degree of plastic deformation, the energy-dissipating ring 21 and the stiffening arc rod 23 can be directly replaced as a whole.

[0085] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
