[0001] The utility model relates to the technical field of transmission lines, in particular to an automatic reset damping spacer dampener. Background Art

[0002] Transmission towers are regarded as key facilities for power supply in various regions of our country. These flexible tower structures usually have low damping characteristics and may experience severe vibrations under external excitation. As the backbone of supporting transmission lines, transmission towers may be damaged or even collapsed in extreme cases, resulting in the interruption of transmission lines. Such accidents may cause serious consequences such as long-term power outages, interruption of user power supply, grid instability, system collapse, and large-scale power outages, so special attention should be paid.

[0003] In order to prevent the adverse effects brought by the vibration of transmission lines, it is necessary to use spacer dampeners to maintain the distance between conductors, and suppress the aeolian vibration, sub-span vibration and galloping through the spacer dampeners to ensure the safe operation of the line.

Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0029] As Figures 1 to 9As shown in the figure, the present application provides an automatic reset damping spacer, which includes a frame body 1, a wire clamp 18, and a buffer mechanism connected between the frame body 1 and the wire clamp 18. The buffer mechanism includes an upper mass block 3, a lower mass block 4, a buffer rod 7, an installation sleeve 9, a first buffer spring 8, a retaining ring 14, a second buffer spring 19, a movable sleeve 6, a plurality of third buffer springs 12, a plurality of sliding connectors 11, a plurality of first buffer arms 51, a plurality of second buffer arms 52, a first limiting member 101, and a second limiting member 102; the lower mass block 4 is arranged at an interval from the upper mass block 3; the upper end of the buffer rod 7 is connected to the lower end of the upper mass block 3. The buffer rod 7 includes a first rod section 71, a second rod section 72, a third rod section 73, and a fourth rod section 74 connected in sequence along its axial direction. The outer diameter of the first rod section 71 is greater than the outer diameter of the second rod section 72, the outer diameter of the third rod section 73 is greater than the outer diameter of the second rod section 72, and the outer diameter of the fourth rod section 74 is smaller than the outer diameter of the third rod section 73; the lower end of the installation sleeve 9 is fixedly connected to the upper end of the lower mass block 4. The installation sleeve 9 has a cavity 91 and an upper opening 92 communicating with the cavity 91. The first buffer spring 8 is sleeved on the second rod section 72; the second buffer spring 19 is sleeved on the fourth rod section 74, and the third rod section 73, the fourth rod section 74, and the second buffer spring 19 extend into the cavity 91 from the upper opening 92; the retaining ring 14 is sleeved on the second rod section 72 and fixedly connected to the upper end of the installation sleeve 9; the movable sleeve 6 includes a sleeve body 61 and a connecting rod 62 protruding from the outer peripheral surface of the sleeve body 61. A plurality of connecting rods 62 are arranged at intervals around the outer peripheral side of the sleeve body 61. The sleeve body 61 is movably sleeved on the outside of the installation sleeve 9. The first limiting member 101 and the second limiting member 102 are respectively fixedly connected to the installation sleeve 9 and are respectively located on the upper and lower sides of the sleeve body 61; a third buffer spring 12 and a sliding connector 11 are sequentially sleeved on each connecting rod 62, and the sliding connector 11 is slidably connected to the connecting rod 62; the first ends of the plurality of first buffer arms 51 are all hinged to the upper mass block 3, and the second ends of the plurality of first buffer arms 51 are respectively hinged to the plurality of sliding connectors 11 in one-to-one correspondence; the first ends of the plurality of second buffer arms 52 are all hinged to the lower mass block 4, and the second ends of the plurality of second buffer arms 52 are respectively hinged to the plurality of sliding connectors 11 in one-to-one correspondence.

[0030] When the transmission wire vibrates, a force is applied to the wire clamp 18 by the transmission wire. The wire clamp 18 transfers the force to the upper mass block 3 above. The upper mass block 3 drives the buffer rod 7, the first buffer arm 51, and the second buffer arm 52 to move. When the buffer rod 7 moves, it drives the first buffer spring 8 and the second buffer spring 19 to move. When the first buffer arm 51 and the second buffer arm 52 move, they drive the sliding connector 11, the third buffer spring 12, and the movable sleeve 6 to move for force unloading. After the force unloading is completed, the first buffer spring 8 and the second buffer spring 19 drive the buffer rod 7 to automatically reset, and the third buffer spring 12 drives the sliding connector 11, the first buffer arm 51, the second buffer arm 52, and the movable sleeve 6 to automatically reset. The automatic reset damping spacer provided by this application can disperse the vibration energy in multiple directions, reduce the vibration amplitude of the tower and wire, have an efficient vibration damping effect, and significantly improve the damping performance and stability of the damping spacer.

[0031] Optionally, as Figure 8 shown, the wire clamp 18 and the upper mass block 3 are fixedly connected by a first pin shaft 131 and a first pin 171. In this way, the connection is convenient and the cost is low. The wire clamp 18 and the upper mass block 3 are in full contact and in a completely butted state. The left and right swinging of the wire clamp 18 will be restricted by the upper mass block 3. The width of the wire clamp 18 is smaller than the width of the upper mass block 3, so that there is no left-right swinging between the wire clamp 18 and the upper mass block 3. Instead, the support arm 2 is used to play a role of left-right swinging, so that the wire clamp 18 can be more effectively fixed between the transmission wires.

[0032] Optionally, as Figures 1 to 3 shown, the lower mass block 4 and the frame body 1 are connected by a support arm 2. The lower mass block 4 and one end of the support arm 2 are fixedly connected by two second pin shafts 132 and two second pins 172. In this way, the connection is convenient and the cost is low.

[0033] Optionally, as Figure 1 and Figure 8 shown, the other end of the support arm 2 is hinged by a stud 15 and a connecting nut 16. In this way, the support arm 2 can swing relative to the frame body 1, and the connection is convenient and the cost is low.

[0034] Optionally, as Figure 5 and Figure 6 shown, both the first limiting member 101 and the second limiting member 102 are limiting nuts. Two threaded structures are provided at intervals on the outer peripheral wall of the mounting sleeve 9. The first limiting member 101 and the second limiting member 102 are respectively in threaded cooperation with the two threaded structures. In this way, the movable sleeve 6 is limited by two limiting nuts, and the installation is convenient and the cost is low.

[0035] Optionally, as Figure 6As shown, the retaining ring 14 is a composite insulating retaining ring. The retaining ring 14 is adhesively bonded to the mounting nut. The retaining ring 14 is provided with a relief hole 141 adapted to the second rod segment 72, and the diameter of the relief hole 141 is smaller than the outer diameter of the third rod segment 73. In this way, the third rod segment 73 is limited by the retaining ring 14 to prevent it from coming out.

[0036] Optionally, as Figure 7 shown, the sliding connector 11 has a mounting hole 111. The mounting hole 111 includes a large hole segment 112 and a small hole segment 113 that communicate with each other. The third buffer spring 12 is in interference fit with the large hole segment 112, and the small hole segment 113 is in transitional fit with the connecting rod 62. The two ends of the third buffer spring 12 are respectively abutted against the sleeve body and the sliding connector 11. In this way, the sliding connector 11 moves driven by the first buffer arm 51 and the second buffer arm 52. The sliding connector 11 can drive the third buffer spring 12 to move, and the sliding connector 11 can drive the movable sleeve 6 to move up and down.

[0037] Optionally, as Figure 4 and Figure 7 shown, the first buffer arm 51 and the upper mass block 3 are hinged by a third pin shaft 133 and a third pin 173; each second buffer arm 52 and the lower mass block 4 are hinged by a third pin shaft 133 and a third pin 173; a corresponding first buffer arm 51 and a second buffer arm 52 are jointly hinged to the corresponding sliding connector 11 by a third pin shaft 133 and a third pin 173. In this way, the assembly is convenient and the cost is low. The first buffer arm 51 can rotate relative to the upper mass block 3, the second buffer arm 52 can rotate relative to the lower mass block 4, and the first buffer arm 51 can rotate relative to the second buffer arm 52.

[0038] Optionally, as Figure 6 shown, the second buffer spring 19 is in clearance fit with the fourth rod segment 74, and the two ends of the second buffer spring 19 are respectively abutted against the bottom wall of the cavity 91 and the lower surface of the third rod segment 73.

[0039] Optionally, the support arm 2 is made of wear-resistant composite material. In this way, it is beneficial to improve the service life of the support arm 2, and further improve the service life of the automatic reset damping spacer.

[0040] Optionally, as Figure 1 shown, the frame body 1 has a plurality of connection ends. The automatic reset damping spacer has a plurality of wire clamps 18 corresponding one-to-one to the plurality of connection ends. A set of buffer mechanisms are provided between a corresponding connection end and a wire clamp 18. The number of connection ends, wire clamps 18 and buffer mechanisms can be set according to actual needs.

[0041] Optionally, as Figure 1As shown, the automatic reset damping spacer is a six-split automatic reset damping spacer. The frame 1 has six equally spaced connection ends, and the automatic reset damping spacer has six wire clamps 18 and six sets of buffer mechanisms corresponding to the six connection ends one by one.

[0042] Optionally, the appearance and installation dimensions of the frame 1 are the same as those of the frame 1 of the existing six-split damping spacer. In this way, the existing six-split damping spacer can be directly replaced, reducing the replacement cost.

[0043] The design of the damping spacer in this patent aims to effectively reduce the structural vibration caused by the vibration of the conductor through a two-way automatic reset mechanism, thereby improving the seismic performance of the tower-line system. This technology has great potential in the field of seismic engineering, can improve the seismic performance of building structures, and reduce the losses caused by conductor breakage. In addition, this technology also helps to improve the structural stability of transmission lines, reduce the risks of structural fatigue and plastic deformation, and thus further improve the overall safety of transmission lines. This patent can greatly reduce the probability of transmission line disconnection caused by severe vibration. This technology is used to reduce the vibration frequency of transmission conductors under external loads, and relates to the field of electrical hardware, especially a damping spacer with automatic reset.

[0044] Given the particularity of the installation position and space of the damping spacer. A specific embodiment of this application provides a six-split automatic reset damping spacer connected to the wire clamp 18, and its structure is as Figures 1 to 9 shown. The main structure includes a frame 1, a support arm 2, an upper mass block 3, a lower mass block 4, a first buffer arm 51 and a second buffer arm 52, a movable sleeve 6, a buffer rod 7, a first buffer spring 8, a mounting sleeve 9, a limit nut, a slidable connecting piece 11, a third buffer spring 12, a first pin 131, a second pin 132, a third pin 133, a retaining ring 14, a stud 15, a connecting nut 16, a first pin 171, a second pin 172, a third pin 173, and a wire clamp 18. The appearance and installation dimensions of the frame 1 of this device are the same as those of the existing six-split spacer. Its core structure is the upper and lower mass blocks 4, the first buffer arm 51 and the second buffer arm 52, the movable sleeve 6, the buffer, two limit nuts (the first limiting member 101 and the second limiting member 102), the slidable connecting piece 11, the first buffer spring 8, the third buffer spring 12, and the wire clamp 18.

[0045] This patent releases the total pressure applied to the clamp 18 from the upper mass block 3 to the lower mass block 4 through the transmission wire. The specific process is as follows: The fixation between the clamp 18 and the upper mass block 3 is achieved through the cooperation of the first pin shaft 131 and the first pin 171. When the transmission wire vibrates up and down, first, the force is transmitted to the upper mass block 3 through the clamp 18. The upper mass block 3 is fixed to the clamp 18 through the first pin shaft 131 and the first pin 171, and this fixation method restricts the left and right degrees of freedom of the clamp 18. The left and right directions mentioned here are Figure 3 the left and right directions shown. Since the direction of the wind force acting on the transmission wire changes randomly, the support arm 2 plays a role of swinging left and right, enabling the clamp 18 to be fixed more effectively between the transmission wires. When the upper mass block 3 bears the force from the clamp 18, these forces are decomposed into horizontal and vertical forces. A part of the vertical force is transmitted from the upper mass block 3 to the buffer rod 7, then to the first buffer spring 8, and finally to the second buffer spring 19 inside the mounting sleeve 9. The horizontal force acts on the slidable connector 11 through the first buffer arm 51 and the second buffer arm 52, and is then transmitted by the slidable connector 11 to the third buffer spring 12, pushing the movable sleeve 6 to move up and down to release the pressure. Finally, the remaining force is transmitted to the lower mass block 4. The lower mass block 4 is fixedly connected to the support arm 2 through the second pin shaft 132 and the second pin 172.

[0046] The upper mass block 3 and the first buffer arm 51 are connected and fixed by the third pin shaft 133 and the third pin 173. Therefore, regardless of whether the wire clamp 18 is under pressure or tension, the upper mass block 3 will drive the first buffer arm 51 to move accordingly. Similarly, the lower mass block 4 and the second buffer arm 52 are connected and fixed by the third pin shaft 133 and the third pin 173. The force between the upper mass block 3 and the first buffer spring 8 is transmitted through the buffer rod 7. Therefore, when the upper mass block 3 is subjected to the pressure of the wire clamp 18, it will compress the buffer rod 7, and then the buffer rod 7 will compress the first buffer spring 8 to provide a buffering and damping effect. The movable sleeve 6 and the mounting sleeve 9 are connected by a clearance fit. The third buffer spring 12 is connected to the slidable connecting member 11 through the movable sleeve 6. The movable sleeve 6 and the slidable connecting member 11 are in a transition fit. Between the movable sleeve 6 and the mounting sleeve 9, the mounting sleeve 9 acts as a slideway and is always fixed on the lower mass block 4 to provide a movement space for the movable sleeve 6, while the first limiting member 101 and the second limiting member 102 limit the movement of the movable sleeve 6 to prevent it from disengaging from the mounting sleeve 9. The lower mass block 4 and the mounting sleeve 9 are in an interference fit. The third buffer spring 12 and the slidable connecting member 11 are connected and fitted through the movable sleeve 6. The movable sleeve 6 and the slidable connecting member 11 are in a transition fit. The third buffer spring 12 and the slidable connecting member 11 are in an interference fit. The first limiting member 101 and the second limiting member 102 are both limiting nuts and are threadedly connected to the mounting sleeve 9. Part of the threads of the mounting sleeve 9 are engaged with the limiting nuts to fix the limiting nuts. The retaining ring 14 is fixed to the mounting sleeve 9 through an adhesive. The lower mass block 4 and the support arm 2 are connected and fixed by the second pin shaft 132 and the second pin 172. The support arm 2 and the frame 1 are connected by a stud 15 and a connecting nut 16. There is a clearance fit between the second buffer spring 19 in the mounting sleeve 9 and the buffer rod 7.

[0047] The buffer is composed of a buffer rod 7, a mounting sleeve 9, a retaining ring 14, and a first buffer spring 8, and is connected to the upper mass block 3 and the lower mass block 4, which can ensure that the horizontal and vertical forces absorbed during the force transmission process can be effectively alleviated and adjusted.

[0048] The movable sleeve 6 cooperates with the third buffer spring 12 and moves within the limit range set by the two limiting nuts to ensure effective absorption of force and reduce energy loss caused by friction during reciprocating motion.

[0049] The upper mass block 3 is fixed to the wire clamp 18 by the first pin shaft 131 and the first pin 171. The upper mass block 3 ensures a uniform and stable distribution of forces during the transmission process, avoiding unnecessary deformations and vibrations, and improving the stability and reliability of the system. This setting helps to improve the stability and reliability of the system, ensuring a uniform and stable force distribution during the transmission process, thereby reducing unnecessary distortions and vibrations. By firmly fixing to the upper part of the wire clamp 18 and the first buffer arm 51, the upper mass block 3 plays a crucial role in achieving these goals.

[0050] The lower mass block 4 is fixed to the support arm 2 by the second pin shaft 132 and the second pin 172, and its function is the same as that of the upper mass block 3.

[0051] The support arm 2 is connected to the frame body 1 and the lower mass block 4. Its main function is to ensure that it can effectively withstand the forces during the transmission process and provide sufficient support stability, avoiding unstable phenomena in the system.

[0052] The combination of the first buffer arm 51, the second buffer arm 52, the slidable connector 11, and the movable sleeve 6 can effectively absorb the impact force and vibration during the transmission process. When the upper mass block 3 is subjected to tension, the first buffer arm 51 and the second buffer arm 52 pull the slidable connector 11 inward, compressing the third buffer spring 12 and causing the movable sleeve 6 to move upward. Conversely, when the upper mass block 3 is subjected to compression, the first buffer arm 51 and the second buffer arm 52 move outward, stretching the third buffer spring 12 and causing the movable sleeve 6 to move downward. The first buffer arm 51 and the second buffer arm 52 help to disperse the pressure generated after the tightening force of the wire clamp 18 is applied, and transmit it evenly to adjacent components. This reduces the risk of damage to individual components due to excessive force transmission and helps to mitigate the sudden impact and vibration caused by force transmission.

[0053] The frame body 1 is connected to the support arm 2, and its functions include support, fixation, force transmission, and strengthening the structure. It is a key component to ensure the performance and stable operation of the spacer damper.

[0054] By limiting and fixing the movement range of the movable sleeve 6, it also functions to adjust the assembly, prevent the buffer from loosening, and protect the equipment, ensuring the normal operation and stability of the equipment.

[0055] The retaining ring 14 is used in combination with the buffer device, which can effectively isolate and insulate the electrical components in the equipment, prevent problems such as electrical breakdown and leakage, and ensure the safety and stability of the system operation.

[0056] The first buffer spring 8 and the buffer rod 7 cooperate to play a role in buffering and vibration reduction.

[0057] The third buffer spring 12 cooperates with the slidable connector 11, the movable sleeve 6, and the mounting sleeve 9 to play a role in resetting. It provides dynamic adaptability and adjusts its shape according to the load and vibration conditions of the tower line.

[0058] The slidable connector 11 is applied together with the first buffer arm 51, the second buffer arm 52, the movable sleeve 6, and the mounting sleeve 9, and can effectively achieve functions such as force transmission, position adjustment, shock absorption and vibration reduction, and improvement of system efficiency, which plays an important role in system stability and operation efficiency.

[0059] The force transmission and unloading process after the clamp 18 is stressed is as follows: clamp 18 - upper mass block 3 - first buffer arm 51, second buffer arm 52 / buffer rod 7 - movable sleeve 6 / mounting sleeve 9 - lower mass block 4 - support arm 2. In this process, the horizontal force and vertical force are absorbed by the buffer composed of the buffer rod 7, the first buffer spring 8, the mounting sleeve 9, and the retaining ring 14; and another part is jointly absorbed by the first buffer arm 51, the second buffer arm 52, the slidable connector 11, the third buffer spring 12, and the movable sleeve 6. After the force unloading is completed, the first buffer spring 8 pushes the buffer rod 7 to reset upward. At the same time, since the third buffer spring 12 is stretched during the force absorption process, when the force disappears, it will cause the slidable connector 11 to move inward, thereby driving the movable sleeve 6 to move upward, and causing the first buffer arm 51 and the second buffer arm 52 to reset accordingly, realizing the automatic reset function.

[0060] The working principle of this application is as follows:

[0061] (1) Force transmission and decomposition: In the application, when the total pressure generated after the clamp 18 is pressed is first transmitted to the upper mass block. The upper mass block, as the main component receiving the pressure, plays an important role in transmitting and decomposing the force, decomposing the pressure into horizontal force and vertical force.

[0062] (2) Transmission process and unloading: The pressure is then transmitted to the movable sleeve 6 through the first buffer arm 51 and the second buffer arm 52 / buffer, and then transmitted to the lower mass block 4 and the support arm 2. In this transmission process, the movable sleeve 6 and the mounting sleeve 9 play a key role in transmitting and unloading the force, effectively absorbing and decomposing the horizontal force and vertical force.

[0063] (3) Force absorption and balance: The movable sleeve 6 and the mounting sleeve 9 used together with the buffer and the first buffer arm 51 and the second buffer arm 52 can absorb and slow down the pressure and balance the action of the force when bearing the horizontal force and vertical force, thereby ensuring the stability and safety of the system during the working process.

[0064] The six-split automatic reset damping spacer of the present application is applicable to various high-voltage transmission lines, especially in wind power generation, long-distance transmission lines, and earthquake-prone areas, which can significantly improve the stability and reliability of power transmission.

[0065] Compared with traditional spacers, the present application adds buffer arms, buffers, springs, etc. to increase the structure that can reduce vibration and automatically reset. Traditional spacers perform poorly in damping the vibration of transmission conductors, while this patent can significantly improve the damping performance and stability of the spacer, especially when facing extreme environmental challenges. Currently, domestic and foreign scholars mainly focus on the installation and improvement of internal dampers in spacers. Although the existing designs achieve vibration reduction through damping devices, there is no adjustment space inside after the clamp 18 is fixed. In addition, under strong wind conditions, the damping device of the damping spacer increases the wind exposure area, making it more unstable under greater wind force. This situation may further affect the safety of the transmission line. In this patent, the damping device is installed below the clamp, and the support arm provides the ability to swing left and right, and the use of the damping spacer will not be affected by strong wind.

[0066] Advantages and effects of the present application:

[0067] 1. High-efficiency vibration damping: The clamp 18, upper mass block 3, first buffer arm 51 and second buffer arm 52, buffer, movable sleeve 6 and mounting sleeve 9, lower mass block 4, support arm 2, first buffer spring 8, second buffer spring 19 and third buffer spring 12 together form an automatic reset adjustable buffer device, which disperses the vibration energy in multiple directions and reduces the vibration amplitude of the tower line.

[0068] 2. Wear-resistant and durable: The use of the support arm 2 supported by composite materials significantly extends the service life of the spacer and reduces the maintenance cost.

[0069] 3. Strong adaptability: The elastic characteristics of the telescopic spring enable the spacer to adapt to the telescopic changes of the tower line and improve the dynamic response ability of the system.
