Description

Technical Field

[0001] The present invention relates to the technical field of power transmission towers, and in particular to a buffer connection device for a tension-resistant power transmission tower. Background Art

[0002] In power transmission systems, tension-type transmission towers are critical load-bearing nodes. They must not only withstand the long-term static tension of the conductors but also cope with dynamic loads generated by various complex weather and operating conditions. The conductors and the crossarms of the tension-type towers are typically connected via strings of tension insulators. Currently, these connection nodes primarily exist in the following two forms and have corresponding technical drawbacks: The first is the traditional rigid connection method. This method is simple in structure and low in cost, but its connection points are rigid and lack any buffering capacity. When the line encounters extreme conditions such as strong winds, ice shedding, or line breakage, it generates enormous dynamic tension shocks. This impact force acts directly on the tower crossarms through the insulator strings without any attenuation, easily causing stress concentration at the connection points. Long-term reciprocating dynamic loads accelerate structural fatigue and, in severe cases, may even damage the crossarms and cause fastener failure, posing a significant threat to the safe and stable operation of the entire line.

[0003] The second method is to use some existing buffer devices. In order to solve the defects of rigid connection, some connection devices with buffer functions have appeared in the prior art, such as using springs or hydraulic dampers to absorb axial impact. However, these existing buffer devices still have obvious shortcomings in practical applications: First, their single function makes them incapable of handling complex loads. Existing buffers are mostly designed for impacts on the longitudinal (axial) direction of the conductor, and their buffering effect is primarily limited to one-dimensional linear motion. However, when subjected to wind, conductors experience not only changes in longitudinal tension but also high-frequency vertical vibrations (wind vibration) and low-frequency, large-amplitude horizontal elliptical motions (galloping). These complex, multi-directional loads are difficult for existing single-function buffers to effectively suppress.

[0004] Second, they suffer from poor outdoor weather resistance and low reliability. Transmission tower connections are exposed to the elements for extended periods, subjecting them to harsh environments like rain, snow, ice, dust, sunlight, and temperature fluctuations. Existing buffers often have moving parts (such as piston rods, springs, and sliding surfaces) that are directly or indirectly exposed to the elements. These components are susceptible to rust, dust intrusion, or ice formation, leading to poor movement, drastic changes in friction coefficient, and even complete seizure. This severely degrades the intended buffering function over time, even causing it to completely fail, making reliable operation throughout its lifecycle impossible.

[0005] Therefore, how to design a buffer connection node for tension-resistant transmission towers that can effectively buffer the large longitudinal impact of the line, suppress multi-directional composite vibrations, have high reliability and long life, and adapt to harsh outdoor environments is a technical problem that needs to be solved urgently in this field. Summary of the Invention

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1 -Attached Figure 8 , the present invention is described in further detail.

[0023] The present invention provides a buffer connection device for a tension-resistant transmission tower, comprising a support frame 1, wherein a plurality of isolation components 2 are symmetrically arranged on the upper surface of the support frame 1, a slide seat 3 is slidably connected to the interior of the isolation component 2, and a connecting rod 4 is fixedly connected to the outer surface of the slide seat 3, a disc spring group 5 is arranged between the outer surface of the slide seat 3 and the inner wall of the isolation component 2, and the disc spring group 5 is sleeved on the outer surface of the connecting rod 4, a telescopic rod 6 and a spring 7 are fixedly connected between the outer surface of the slide seat 3 and the inner wall of the isolation component 2, and the spring 7 is sleeved on the outer surface of the telescopic rod 6, and the telescopic rod 6 is located on both sides of the connecting rod 4, a buffer component 8 is arranged inside the slide seat 3, and an omnidirectional damping component 9 is arranged at one end of the connecting rod 4 outside the isolation component 2.

[0024] Specifically, the support frame 1 provides a solid foundation for the entire device to be connected to the tower arm, bearing all static and dynamic loads; the isolation component 2 above it creates a critical closed environment, which is designed to isolate the internal core motion mechanism from the outside world, thereby ensuring that its functions can be reliably realized for a long time in adverse climates; when the force of the external line is transmitted to the device through the connecting rod 4, the omnidirectional damping component 9 at its end will continuously generate friction torque on the multi-directional swing of the conductor 18 caused by the wind, and achieve the effect of suppressing the wind deviation and dancing of the line by consuming vibration energy; at the same time, the longitudinal impact force of the line is firstly provided by the disc spring group 5 mounted on the outer surface of the connecting rod 4 and the position The springs 7 on both sides thereof perform the first-level elastic buffering. The two sets of springs work together to effectively absorb conventional, small-scale dynamic impact energy. At this time, the slide 3 remains stationary. When encountering extreme situations such as line breakage, when the impact energy is so huge that it exceeds the absorption limit of the first-level buffering, the connecting rod 4 will drive the slide 3 to slide. This sliding process will immediately activate the buffer component 8 located inside the slide 3. The component generates a strong sliding friction force with the inner wall of the isolation component 2 through its internal friction pair, and efficiently converts the macroscopic, destructive impact kinetic energy into heat energy and dissipates it, thereby achieving the ultimate buffering of the impact force and effectively protecting the safety of the tower structure.

[0025] The isolation assembly 2 includes a closed box 201, which is flange-connected to the upper surface of the support frame 1. The interior of the closed box 201 is fixedly connected to a slide rail 202, and the slide seat 3 is slidably connected to the outer surface of the slide rail 202. On both sides of the slide seat 3, the inner wall of the closed box 201 is fixedly connected to a friction layer 203, and a water outlet hole 204 is provided at the inner bottom edge of the closed box 201. The top of the closed box 201 is rotatably connected to an inspection cover 205.

[0026] Specifically, the main function of the closed box 201 is to build a solid sealed shell, which completely isolates the internal precision movement and buffer mechanism from the harsh environment of rain, snow, sand and dust, so as to ensure the long-term stable operation of the entire device; a slide rail 202 is provided inside the closed box 201, which provides a precise and low-resistance sliding guide path for the slide 3, ensuring that under the action of a huge impact force, the slide 3 can smoothly perform linear motion to activate the secondary buffer; as a key component of the secondary buffer system, the friction layer 203 fixed on the inner wall It is a static friction surface that generates energy dissipation. When the slide 3 slides, it cooperates with the friction pair on the slide 3 to generate huge friction, converting the impact kinetic energy into heat energy. In order to prevent condensation water from being generated due to temperature changes in the box and affecting the internal parts, the specially opened water outlet 204 can realize the automatic discharge of internal accumulated water, which plays an auxiliary effect of self-cleaning and drying. The inspection cover 205 on the top provides a convenient entrance for necessary maintenance work, allowing personnel to inspect or replace internal components without disassembling the entire device, which greatly improves maintainability.

[0027] The buffer assembly 8 includes multiple guide shafts 801, which are fixedly connected to the outer surface of the slide 3. Two buffer blocks 802 are slidably connected to the outer surface of the guide shaft 801. A spring 2 803 is fixedly connected between one side of the outer surface of the buffer block 802 and the outer surface of the slide 3. A friction layer 2 804 is fixedly connected to the other side of the outer surface of the buffer block 802. The friction layer 2 804 abuts against the friction layer 1 203.

[0028] Specifically, spring 2 803 is pre-compressed and stores a large amount of elastic potential energy, thereby providing a continuous and stable normal preload for the entire friction system; this force is applied to the buffer block 802, so that it always has a tendency to expand outward, and the guide shaft 801 provides precise guidance for the movement of the buffer block 802 in this process, ensuring that it moves smoothly along the preset path and transmits the thrust of the spring to the friction surface without deviation and vertically; finally, the force acts on the friction layer 2 804 fixed to the outside of the buffer block 802, so that it fits tightly with the friction layer 1 203 on the inner wall of the closed box 201 and generates a huge positive pressure. When the slide 3 slides under the drive of an external force, a strong sliding friction force will be generated between the two friction layers, thereby efficiently converting the macroscopic kinetic energy causing the impact into heat energy, achieving the ultimate goal of dissipating energy and buffering the impact. The omnidirectional damping assembly 9 includes a friction ball 901 and a wrapping shell 902. The friction ball 901 is fixedly connected to one end of the connecting rod 4. The interior of the wrapping shell 902 is slidably connected to a fan-shaped friction surface 903. The outer surface of the fan-shaped friction surface 903 is fixedly connected to a guide rod 904. One end of the guide rod 904 passes through the wrapping shell 902. The wrapping shell 902 and the fan-shaped friction surface 903 are installed on the outer surface of the friction ball 901. A spring three 905 is fixedly connected between the outer surface of the fan-shaped friction surface 903 and the wall of the wrapping shell 902. The spring three 905 is sleeved on the outer surface of the guide rod 904.

[0029] Specifically, the omnidirectional damping assembly 9 is used to suppress multi-directional vibrations of the line caused by factors such as wind. Its core function lies in spring three 905, which, when preloaded, provides a continuous, controllable normal pressure to the entire system. This preload acts directly on the spherical surface of the friction ball 901 through the fan-shaped friction surface 903, generating a huge static friction torque at their contact interface. When the line swings, the friction ball 901 connected to the line attempts to rotate. At this time, it must overcome the aforementioned static friction torque to move. In this process, the vibration kinetic energy of the line is efficiently converted into heat energy and dissipated. During this period, the guide rod 904 provides precise guidance for the radial movement of the fan-shaped friction surface 903, ensuring that the pressure applied by the spring can be evenly and stably transmitted to the surface of the friction ball 901. The encapsulating shell 902 serves as the solid outer shell and reaction base of the entire assembly. It not only integrates all internal components into a single unit, but also withstands all the forces applied by the spring, thus providing the necessary structural support for the realization of the entire friction energy dissipation process.

[0030] At the connection between the outer surface of the connecting rod 4 and the closed box 201 , a flexible ring 10 is fixedly connected to the interior of the closed box 201 . The flexible ring 10 is located between the outer surface of the connecting rod 4 and the inner wall of the closed box 201 .

[0031] Specifically, the flexible ring 10 undertakes a vital dynamic sealing function, and its core role is to maintain the airtightness of the internal environment of the closed box 201 while allowing the connecting rod 4 to perform axial reciprocating motion; specifically, when the connecting rod 4 slides due to force, the flexible ring 10 fits tightly to the outer surface of the connecting rod 4 by virtue of its own elasticity, forming a reliable movable sealing barrier, which can effectively prevent external pollutants such as rainwater, sand and dust from invading the interior of the closed box 201 along the surface of the rod, thereby directly protecting the core mechanisms such as the precise slide rail 202 and the buffer assembly 8, ensuring that they will not function due to pollution or rust.

[0032] In the moving direction of the slide 3 , a safety pin 11 is fixedly connected to the inner wall of the closing box 201 , and a shear cut 12 is formed on the outer surface of the safety pin 11 .

[0033] Specifically, the safety pin 11 is the ultimate safety protection mechanism set up to deal with extreme catastrophic impacts. It is essentially a mechanical "fuse" and will not be triggered under normal operation and general impact conditions; but when the impact energy is too large, so that the aforementioned first and second level buffer systems have reached their energy absorption limits, the slide 3 will continue to move and eventually hit the safety pin 11; at this time, the shear cut 12 preset on the outer surface of the safety pin 11 plays a key stress concentration role, which ensures that under the action of the huge impact force, the safety pin 11 will undergo controllable shear fracture at the preset weak point; in this shear fracture process, the remaining and most destructive impact kinetic energy of the slide 3 is converted into the energy required to cause the safety pin 11 to undergo plastic deformation and ultimate fracture, and is thus completely consumed. This process uses the controllable failure of a low-cost component to successfully avoid structural damage that may be caused by a rigid collision between the slide 3 and the end wall of the closed box 201.

[0034] The outer surface of the closed box 201 is fixedly connected with heat dissipation fins 13 .

[0035] Specifically, the function of the heat dissipation fins 13 is to promptly and effectively dissipate the huge amount of heat generated by the operation of the secondary buffer system. By increasing the contact surface area between the box and the outside air, the accumulated heat can be quickly dissipated to the surrounding environment, thereby effectively avoiding the risk of excessive accumulation of heat in the closed cavity and causing performance degradation of internal key components (such as friction materials) due to high temperature.

[0036] The sliding seat 3, the closing box 201 and the inspection cover 205 are all provided with locking holes 14. The locking holes 14 provided in the sliding seat 3, the closing box 201 and the inspection cover 205 are located on the same axis. The locking holes 14 are slidably connected with locking columns 15.

[0037] Specifically, the locking hole 14 and the locking column 15 together constitute an auxiliary locking system, the function of which is to temporarily and rigidly fix the internal movable parts during the factory transportation and on-site installation stages of the device; specifically, by inserting the locking column 15 into and passing through multiple locking holes 14 located on the same axis, the core moving component slide 3 can be reliably and rigidly connected to the stationary closed box 201 and the inspection cover 205, thereby preventing the slide 3 from any unnecessary reciprocating sliding during transportation bumps or installation and handling; this pre-locked state effectively protects the internal spring group and friction pair and other precision components from pre-wear or impact damage, ensuring that the initial state of the device is intact before it is officially put into use; after the entire device is installed in place on the pole tower, it is only necessary to pull the locking column 15 out of the locking hole 14 to release the locking state, allowing the slide 3 to resume its free sliding function, so that the entire buffer system can respond to the impact load of the line at any time. An insulator string 16 is hinged on the outer surface of the encapsulating shell 902, and a connecting frame 17 is hinged on the outside of the insulator string 16. A conductor 18 is fixedly connected to the inside of the connecting frame 17. The two conductors 18 are connected by a connecting clip 19, and the connecting clip 19 is fixedly connected to the lower surface of the connecting frame 17 through an insulator 20.

[0038] Specifically, in order to reliably fix the conductor 18, the connecting frame 17 provides a stable structural terminal to collect the mechanical force of the line; to ensure the electrical continuity of the line at the structural terminal, the connecting clip 19 plays a key current bridging role, thereby allowing the power to flow smoothly; and the independent insulator 20 provides the necessary ground insulation for this bridging loop to prevent short circuits; thereafter, all the mechanical loads borne by the entire connecting frame 17 are transmitted through the main insulator string 16. The core function of the insulator string 16 is to effectively transmit huge pulling force while achieving reliable electrical isolation between the high-voltage conductor 18 and subsequent grounding components, thereby ensuring the safety of the power grid.

[0039] A bellows 21 is installed on the outside of the wrapping shell 902 , and an air vent 22 is provided on the outer surface of the bellows 21 away from the wrapping shell 902 .

[0040] Specifically, the bellows 21 is used to effectively seal the movable joints of the omnidirectional damping assembly 9 while allowing the internal guide rod 904 to move. It compensates for the movement stroke through its own expansion and contraction deformation, thereby preventing external solid or liquid pollutants such as rainwater and dust from invading the interior of the encapsulating shell 902, ensuring the cleanliness of its working environment; in order to eliminate the pressure difference between the inside and outside of the bellows 21, the air vent 22 is opened to play a key role in balancing the internal and external air pressure. It allows air to freely enter and exit when the bellows 21 expands and contracts, thereby ensuring that the movement of the internal damping element will only be affected by the preset friction force.

[0041] Working principle: Before installation, except for the hinged part and the part connected to the conductor 18, the other parts of the present invention are all integrated into one before leaving the factory, and the locking column 15 is inserted into the locking hole 14. The locking column 15 is used to protect the equipment before the equipment is installed on the spot to prevent the friction layer 203 and other parts in the closed box 201 from being worn before use; when installing this equipment, first fix the support frame 1 on the transmission tower, and then hinge the insulator string 16, the connecting frame 17 and the wrapping shell 902, and then pass the conductor 18 through the two connecting frames 17 and fix them with the connecting buckle 19, and finally fix the connecting buckle 19 to the bottom of the support frame 1 through the insulator 20. 18 and the conductor 18 are slightly moved. When the wire 18 dances greatly or breaks or falls off due to ice, the axial impact force on the wire 18 is transmitted to the slide 3 inside the closed box 201. At this time, the primary buffer layer composed of the disc spring group 5 and the spring 1 7 is not enough to completely absorb the axial impact force. The slide 3 is pulled by the connecting rod 4. At the same time, the friction layer 1 203 on both sides of the buffer block 802 in the slide 3 and the friction layer 2 804 on the inner wall of the closed box 201 generate a huge static friction torque to suppress the occurrence and development of vibration, and the spring 2 803 in the slide 3 continuously provides positive pressure for the buffer block 802. Outside the closed box 201, the angle of the wire 18 changes accordingly, and the fan-shaped friction layer 804 in the wrapping shell 902 is used to wrap the wire 18. The huge static friction torque between the friction surface 903 and the friction ball 901 suppresses the occurrence and development of vibration and maintains the stability of the line. When facing extreme impact loads that far exceed the design standards (for example, large-scale continuous tower collapses occur near the line), the above-mentioned buffering process is repeated. However, the external impact load is too large at this time, causing the slide 3 to continuously squeeze the safety pin 11. In order to protect the expensive main structure of the tower, a weak shear buckle is opened on the outer surface of the safety pin 11. At this time, the safety pin 11 will break along its cross section at the shear cut 12, converting the huge impact kinetic energy into plastic deformation energy that deforms the safety pin 11, thereby reducing damage to the tower body and related components such as the closing box 201.

[0042] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
