Description

Technical Field

[0001] The utility model relates to the technical field of transmission line electrical hardware, and particularly relates to a spacer damper.

Background Art

[0002] High-altitude transmission conductors generally adopt a transmission method in which multiple sub-conductors are connected in parallel. Under the action of wind, the transmission line will have frequent aeolian vibrations, resulting in the conductors sticking together, which can easily lead to circuit short circuits, wire fatigue, and damage to electrical hardware and tower components. The use of a spacer damper can ensure that the distance between the sub-conductor bundles remains unchanged, reduce the surface potential gradient, and play a certain role in suppressing sub-span oscillations and aeolian vibrations.

[0003] However, the installation method of the existing transmission line spacer damper requires workers to climb the iron tower for manual pin insertion and fixation. The installation process is complicated and dangerous, consuming a lot of labor and restricting the construction progress at the same time.

Content of the Utility Model

[0004] To solve the technical problem that the installation and construction of the existing transmission line spacer damper consume a large amount of labor and have potential safety hazards, the utility model provides a spacer damper.

A clamping space is provided on the first wire clamp, and a stop member is arranged in the clamping space. A telescopic assembly is arranged on the second wire clamp corresponding to the clamping space. When the second wire clamp is buckled with the first wire clamp, the telescopic assembly contracts and then crosses the stop member and enters the clamping space, and the telescopic assembly extends out and is clamped with the stop member.

[0006] Preferably, the first wire clamp includes a first buckle, the second wire clamp includes a second buckle, the first buckle and the second buckle are rotatably connected, and the first buckle and the second buckle enclose a receiving space.

[0007] Preferably, a clamping portion is connected to the end of the second buckle away from the first buckle, and a limiting groove is formed on the clamping portion, and the telescopic assembly is arranged in the limiting groove.

[0008] Preferably, the telescopic assembly includes a telescopic rod and a telescopic block connected to each other. A stop member and an elastic member abutting against the stop member are arranged on the telescopic rod. One end of the telescopic rod is connected to the telescopic block, and the other end is connected to the limiting groove.

[0009] Preferably, the side of the telescopic block away from the telescopic rod is set as an inclined surface.

[0010] Preferably, a connecting hole is provided on the main body, the first wire clamp includes a connecting portion, the connecting portion is provided with a first limiting hole and a first limiting member, and when the first limiting member is fixed in the first limiting hole and cooperates with the connecting hole, there is a movable space in the connecting hole.

[0011] Preferably, a rotating assembly and a second limiting member are connected inside the main body, a through hole is provided inside the rotating assembly, a second limiting hole is opened on the main body corresponding to the through hole, and the second limiting member is fixed to the through hole and cooperates with the second limiting hole.

[0012] Preferably, a rotating hole is provided on the first wire clamp corresponding to the rotating component, a limiting protrusion is provided in the rotating hole corresponding to the rotating component, the limiting protrusion limits the rotation of the rotating component in the rotating hole, and there is a gap between the limiting protrusion and the rotating component.

[0013] Preferably, elastic pads are provided inside the first buckle and the second buckle.

[0014] Preferably, the spacer bar is a two-split spacer bar, and the spacer bar comprises two wire clamp assemblies, and the two wire clamp assemblies are symmetrically arranged about the central axis of the main body.

[0015] Compared with the prior art, the spacer provided by the utility model has the following advantages:

[0016] 1. The utility model provides a spacer rod, in which a telescopic assembly cooperates with a stopper to lock a second wire clamp. When the second wire clamp is buckled with the first wire clamp, the telescopic assembly will shrink and pass over the stopper, and then expand and engage with the stopper to achieve automatic buckling of the end of the second wire clamp with the first wire clamp; the first wire clamp and the second wire clamp are firmly connected and cooperated with the telescopic assembly through the stopper to effectively resist breeze vibration and maintain a constant spacing width.

[0017] 2. The utility model provides a spacer rod. When the stopper in the first wire clamp is engaged with the telescopic component on the second wire clamp, the accommodation space formed by the first buckle and the second buckle accommodates the sub-conductor to ensure that two adjacent sub-conductors will not stick together. The buckle can be used for quick connection and release, making assembly and disassembly more convenient and efficient, without the need for additional tools or complicated operations.

[0018] 3. The utility model provides a spacer rod, and the limiting groove can provide precise position control to ensure that the telescopic component can be accurately positioned and fixed when connected to the positioning space, which can effectively prevent misoperation or accidents. The limiting groove limits the movement range of the telescopic component and improves the stability and safety of the connection.

[0019] 4. A spacer bar provided by the present utility model, wherein the telescopic rod is restricted within the limit groove. When the telescopic block abuts against the stop member, the telescopic rod is forced to contract, and the stop member pushes the elastic member to deform it. When the telescopic block completely enters the clamping space and is parallel to the length direction of the first wire clamp or the second wire clamp, the elastic member is no longer compressed and returns to its original state to push more parts of the telescopic block into the clamping space. At this time, the telescopic block abuts against the stop member, completing the locking of the second wire clamp and the first wire clamp; the telescopic rod has a certain elasticity, which can absorb and reduce external impacts and vibrations, protecting the stability of the connection. The telescopic block and the stop member ensure that the elastic member can be locked in a suitable position after the locking is completed.

[0020] 5. A spacer bar provided by the present utility model, during the rotation of the second wire clamp, the telescopic block abuts against the telescopic stop member along the inclined plane, enabling the second wire clamp to rotate smoothly and causing the telescopic block to gradually retract until the inclined plane completely enters the clamping space. The elastic member rebounds and drives the telescopic block to extend. The inclined plane avoids the conflict between the corresponding end face and the stop member during the rotation of the second wire clamp, resulting in the interruption of rotation.

[0021] 6. A spacer bar provided by the present utility model connects the first wire clamp and the main body through the cooperation of the first limiting hole, the first limiting member and the connection hole. When the first limiting member is fixed in the first limiting hole and cooperates with the connection hole, there is an activity space for the first limiting member in the connection hole, enabling the first wire clamp to perform activities with certain preset angle and width limitations, helping to better clamp sub-conductors with different wire distances and heights.

[0022] 7. A spacer bar provided by the present utility model, the second limiting member disposed in the through hole within the rotating assembly cooperates with the rotating hole on the first wire clamp, further stabilizing the connection between the first wire clamp and the main body. At the same time, the rotating assembly can rotate at a certain angle within the rotating hole to adapt to sub-conductors to be clamped at different heights. The limiting protrusion within the rotating hole restricts the rotation of the rotating assembly, causing the rotation of the rotating assembly to occur in the direction and at the angle defined by the limiting protrusion, and the limiting protrusion prevents accidental rotation or loosening, ensuring the stability and reliability of the connection. Once correctly installed and fixed, the connection between the first wire clamp and the main body is not easily affected by external vibrations or movements.

[0023] 8. A spacer bar provided by the present utility model, elastic pads are provided inside the first buckle and the second buckle. When clamping the wire, it can increase the contact area and friction with the wire, facilitating the fixation of the wire, preventing the wire from falling off, and at the same time providing a certain buffering effect on the wire, avoiding excessive extrusion and damaging the wire, affecting the use of the wire.

For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present utility model can be understood according to specific circumstances.

[0041] In addition, the terms "installed", "set", "provided with", "connected", "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is an internal connection between two devices, elements or components.

[0042] Please refer to Figure 1 and Figure 2 , the first embodiment of the present utility model provides a spacer 100, which includes a main body 1 and a wire clamp assembly 2 connected to the main body 1. The wire clamp assembly 2 includes a first wire clamp 21 connected to one end of the main body 1 and a second wire clamp 22 rotatably connected to the end of the first wire clamp 21 away from the main body 1. A clamping position space 213 is provided on the first wire clamp 21, and a stop member 4 is arranged in the clamping position space 213. A telescopic assembly 3 is correspondingly arranged on the second wire clamp 22 at the position corresponding to the clamping position space 213. When the second wire clamp 22 is buckled with the first wire clamp 21, the telescopic assembly 3 contracts and then crosses the stop member 4 and enters the clamping position space 213. When the telescopic assembly 3 extends, it is clamped with the stop member 4.

[0043] Specifically, the first wire clamp 21 includes a first buckle 211 and a connecting portion 212. The first buckle 211 and the connecting portion 212 are integrally formed and manufactured as a single component. The positioning space 213 is provided as a hollow chamber within the connecting portion 212, and a hole for the stopper 4 is formed on the connecting portion 212 to allow the stopper 4 to pass through.

[0044] The stopper 4 can be made of wear-resistant stainless steel. Optionally, the stopper 4 can be a pin with a round head at one end and fixed to the connecting portion 212 by a pin at the other end, or other position-limiting devices for movable connection can also be used, as long as it can limit the rotation of the second wire clamp 22 within the positioning space 213. There is no specific limitation in the present utility model.

[0045] Specifically, the second wire clamp 22 includes a second buckle 221 and a positioning portion 222. The second buckle 221 and the positioning portion 222 are integrally formed, having higher durability.

[0046] Furthermore, when the wire clamp assembly 2 is in the closed state, the first buckle 211 and the second buckle 221 enclose to form an accommodation space 24 to accommodate the sub-conductor to be clamped, and at this time, a part of the second wire clamp 22 is accommodated within the positioning space 213.

[0047] When the wire clamp assembly 2 is in the open state, the first wire clamp 21 and the second wire clamp 22 are opened at an angle. The spacer 100 and its clamping assembly are stretched into the air by a drone. The sub-conductor to be clamped passes through the accommodation space 24 between the first wire clamp 21 and the second wire clamp 22. The pneumatic structure on the clamping assembly pushes the second wire clamp 22 towards the positioning space 213. During the pushing process, the telescopic assembly 3 abuts against the stopper 4 and contracts until the first buckle 211 and the second buckle 221 are engaged. A part of the telescopic assembly 3 enters the positioning space 213. The pneumatic assembly stops applying force. The telescopic assembly 3 extends and is clamped with the stopper 4, and the telescopic assembly 3 is restricted within the positioning space 213 to keep the second wire clamp 22 and the first wire clamp 21 latched, realizing the automatic locking of the first wire clamp 21 and the second wire clamp 22.

[0048] Among them, the first buckle 211 and the second buckle 221 are rotationally connected at one end through a bolt, or other connection methods such as fixed connection or detachable connection can also be used, as long as the rotational connection between the two can be achieved. There is no limitation in the present utility model.

[0049] In a specific embodiment, the main body 1 can be one or more plates. Its shape can be long strip-shaped, quadrilateral or other shapes. The multiple plates are arranged in parallel. The material can be metals such as iron, copper, chromium or non-metals, as long as it can cooperate with the wire clamp assembly 2 to space the electric wires. There is no excessive limitation on its specific shape, material, etc. here, and it can be specifically set according to the actual situation.

[0050] In particular, the number of the clamp assemblies 2 generally matches the number of bundles of high-voltage cables to be spaced apart, that is, two bundles, four bundles, six bundles, etc. A spacer 100 provided by the present utility model is matched with two-conductor wires and is a two-split spacer 100. The spacer 100 includes two clamp assemblies 2, and the two clamp assemblies 2 are symmetrically arranged with respect to the center axis of the main body 1.

[0051] Further, please refer to Figures 3 - 4 , the positioning portion 222 of the second buckle 221 is arranged at the end far from the first buckle 211, and a limiting groove 223 is formed on the positioning portion 222, and the telescopic assembly 3 is arranged in the limiting groove 223.

[0052] Further, please refer to Figures 5 - 6 , the telescopic assembly 3 includes a telescopic rod 31 and a telescopic block 32 connected to each other. A stop member 33 and an elastic member 34 abutted against the stop member 33 are provided on the telescopic rod 31. One end of the telescopic rod 31 is connected to the telescopic block 32, and one end is connected to the limiting groove 223.

[0053] In a feasible implementation manner, the limiting groove 223 is arranged along the length direction of the positioning portion 222 and penetrates through the entire positioning portion 222, and the telescopic assembly 3 is installed in the limiting groove 223.

[0054] Optionally, the elastic member 34 may be one or more of a helical spring, a torsion bar spring, a rubber spring, a spring sheet or other elastic parts.

[0055] It should be noted that when the telescopic block 32 abuts against the stop member 4, the telescopic block 32 retracts inward under the abutting force, so that the stop member 33 on the telescopic rod 31 abuts against and compresses the elastic member 34 to cause elastic deformation thereof; when the second clamp 22 rotates to the first buckle 211 and the second buckle 221 are buckled and communicated, the telescopic block 32 completely enters the buckling space 213, and the stop member 4 no longer receives the abutting force of the telescopic block 32. The previously compressed elastic member 34 returns to its original state under the elastic force, and pushes the telescopic block 32 to extend into the buckling space 213 through the stop member 33 and enter the buckling space 213.

[0056] It should be understood that when the telescopic block 32 enters the buckling space 213, if the second clamp 22 rotates relative to the first clamp 21, the stop member 4 restricts the rotation of the second clamp 22.

[0057] Further, please refer to Figure 6 , one side of the telescopic block 32 away from the telescopic rod 31 is provided with an inclined surface 321.

[0058] Understandably, during the rotation of the second wire clamp 22, the telescopic block 32 abuts against the telescopic stopper 4 along the inclined surface 321, and as the second wire clamp 22 rotates, the telescopic block 32 gradually retracts. It should be understood that the inclined surface 321 can make the contact surface between the second wire clamp 22 and the stopper 4 smooth during rotation, thereby making the rotation of the second wire clamp 22 smooth.

[0059] Optionally, the inclination angle of the inclined surface 321 can be 30°, 45°, 60° or other angles, etc.

[0060] Preferably, the inclination angle of the inclined surface 321 in this embodiment is 45°, so that the telescopic block 32 retracts uniformly and receives uniform force with the second wire clamp 22 towards the clamping space 213.

[0061] Furthermore, a connection hole 11 and a first limiting member 12 are provided on the main body 1. When the first limiting member 12 is fixed in the first limiting hole 2121 on the connection portion 212 of the first wire clamp 21 and cooperates with the connection hole 11, there is an activity space in the connection hole 11.

[0062] Specifically, the first limiting member 12 is a cylinder provided on the connection portion 212. After the first wire clamp 21 is connected to the main body 1, the first limiting member 12 is correspondingly fixed in the first limiting hole 2121 and passes through the first limiting hole 2121 to be connected to the connection hole 11. The first limiting member 12 has an activity space in the activity direction of the connection hole 11. When the first wire clamp 21 clamps and accommodates the sub-conductor, the activity space of the first limiting member 12 in the connection hole 11 helps the first wire clamp 21 adapt to sub-conductors of different heights and widths.

[0063] Furthermore, please refer to Figure 3 , a rotating assembly 13 and a second limiting member 14 are connected inside the main body 1. A through hole 131 is provided inside the rotating assembly 13, and a second limiting hole 15 is correspondingly opened on the main body 1. The second limiting member 14 is fixed in the through hole 131 and cooperates with the second limiting hole 15.

[0064] Furthermore, a rotating hole 2122 is correspondingly opened on the connection portion 212 of the first wire clamp 21 for the rotating assembly 13, and a limiting protrusion 2123 is provided in the rotating hole 2122 corresponding to the rotating assembly 13. The limiting protrusion 2123 restricts the rotation of the rotating assembly 13 in the rotating hole 2122.

[0065] The rotating assembly 13 is fixed on the main body 1 and is connected to the first wire clamp 21 through its rotating hole 2122, allowing the connection angle between the first wire clamp 21 and the main body 1 to be adjusted and positioned within a certain range, and performing fine adjustment and adjustment of the angle to adapt to the intervals between separated conductors in different outdoor environments.

[0066] Specifically, please refer to Figure 5The limiting protrusions 2123 are four mutually symmetrical square protrusions, and the rotating component 13 is adaptively provided with four recessed structures. The rotating component 13 and the limiting protrusions 2123 do not abut in the rotating hole 2122, and there is a certain gap L between the two (such as Figure 5 The L in the figure provides a rotation space for the rotating assembly 13 in the rotating hole 2122, but the L between the rotating assembly 13 and the limiting protrusion 2123 (such as Figure 5 The L) in the utility model is not infinitely expanded, and is limited to between 5 cm and 10 cm in the utility model to limit the rotation angle between the first wire clamp 21 and the main body 1, so as to avoid a large rotation of the wire clamp resulting in a reduction in the spacing effect of the sub-conductors.

[0067] Furthermore, elastic pads 23 are disposed inside the first buckle 211 and the second buckle 221 .

[0068] Optionally, the elastic pad 23 may be a rubber pad, a silicone pad, polyurethane, a polyester elastomer, etc.

[0069] It can be understood that by arranging the elastic pad 23 inside the first buckle 211 and the second buckle 221, the wire clamp assembly 2 can increase the contact area and friction between the wire and the wire when clamping the wire, which is convenient for fixing the wire and preventing the wire from falling off. At the same time, it provides a certain buffering effect on the wire to avoid excessive squeezing, damage to the wire, and affecting the use of the wire.

[0070] Compared with the prior art, the spacer provided by the utility model has the following advantages:

[0071] 1. The utility model provides a spacer rod, in which a telescopic assembly cooperates with a stopper to lock a second wire clamp. When the second wire clamp is buckled with the first wire clamp, the telescopic assembly will shrink and pass over the stopper, and then expand and engage with the stopper to achieve automatic buckling of the end of the second wire clamp with the first wire clamp; the first wire clamp and the second wire clamp are firmly connected and cooperated with the telescopic assembly through the stopper to effectively resist breeze vibration and maintain a constant spacing width.

[0072] 2. The utility model provides a spacer rod. When the stopper in the first wire clamp is engaged with the telescopic component on the second wire clamp, the accommodation space formed by the first buckle and the second buckle accommodates the sub-conductor to ensure that two adjacent sub-conductors will not stick together. The buckle can be used for quick connection and release, making assembly and disassembly more convenient and efficient, without the need for additional tools or complicated operations.

[0073] 3. The utility model provides a spacer rod, and the limiting groove can provide precise position control to ensure that the telescopic component can be accurately positioned and fixed when connected to the positioning space, which can effectively prevent misoperation or accidents. The limiting groove limits the movement range of the telescopic component and improves the stability and safety of the connection.

[0074] 4. A spacer bar provided by the present utility model. The telescopic rod is restricted within the limit groove. When the telescopic block abuts against the stop member, the telescopic rod is stressed and contracts. The stop member pushes the elastic member to deform it. When the telescopic block completely enters the clamping space and is parallel to the length direction of the first wire clamp or the second wire clamp, the elastic member is no longer compressed and returns to its original state to push more parts of the telescopic block into the clamping space. At this time, the telescopic block abuts against the stop member, completing the locking of the second wire clamp and the first wire clamp. The telescopic rod has a certain elasticity, which can absorb and reduce external impacts and vibrations, protecting the stability of the connection. The telescopic block and the stop member ensure that the elastic member can be locked in a suitable position after the locking is completed.

[0075] 5. A spacer bar provided by the present utility model. During the rotation of the second wire clamp, the telescopic block abuts against the telescopic stop member along the inclined plane, making the rotation of the second wire clamp smooth and gradually retracting the telescopic block until the inclined plane completely enters the clamping space. The elastic member rebounds and drives the telescopic block to extend. The inclined plane avoids the conflict between the corresponding end face and the stop member during the rotation of the second wire clamp, resulting in the interruption of rotation.

[0076] 6. A spacer bar provided by the present utility model. The first wire clamp is connected to the main body through the cooperation of the first limiting hole, the first limiting member and the connecting hole. When the first limiting member is fixed in the first limiting hole and cooperates with the connecting hole, there is an activity space for the first limiting member in the connecting hole, enabling the first wire clamp to perform activities with certain preset angle and width limitations, helping to better clamp the sub-conductors with different wire distances and heights.

[0077] 7. A spacer bar provided by the present utility model. The second limiting member disposed in the through hole within the rotating assembly cooperates with the rotating hole on the first wire clamp, further stabilizing the connection between the first wire clamp and the main body. At the same time, the rotating assembly can rotate at a certain angle within the rotating hole to adapt to the sub-conductors to be clamped at different heights. The limiting protrusion within the rotating hole restricts the rotation of the rotating assembly, making the rotation of the rotating assembly need to rotate in the direction and at the angle defined by the limiting protrusion, and the limiting protrusion will prevent accidental rotation or loosening, ensuring the stability and reliability of the connection. Once correctly installed and fixed, the connection between the first wire clamp and the main body is not easily affected by external vibrations or movements.

[0078] 8. A spacer bar provided by the present utility model. Elastic pads are provided inside the first buckle and the second buckle. When clamping the wire, it can increase the contact area and friction with the wire, facilitating the fixation of the wire, avoiding the wire from falling off, and at the same time providing a certain buffering effect on the wire, avoiding excessive extrusion, damaging the wire and affecting the use of the wire.

[0079] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
