A high-strength, lightweight braided rope has a separating insulating tube at its outer end. Several internally convex damping strips are equidistantly bonded to the inner end of the separating insulating tube. A raised sealing strip is placed between the high-strength, lightweight braided rope and the separating insulating tube. A flame-retardant wrapping tape is wound around the outer end of the raised sealing tape, and an externally concave damping strip is bonded to the outer end of the flame-retardant wrapping tape.

Description

Technical Field

[0001] This invention relates to the field of overhead line technology, specifically to a lightweight overhead line for high-altitude applications. Background Technology

[0002] Overhead lines typically refer to bare conductors erected above the ground via poles and insulators. They are the most important form of electrical energy transmission in power systems and are mainly divided into overhead power lines, electrified railway contact network conductors, overhead insulated overhead lines, communication overhead open lines, and fiber optic composite overhead ground wires. Overhead power lines are mainly composed of conductors, overhead ground wires, poles, insulators, hardware, foundations, and grounding devices.

[0003] However, existing overhead power lines, due to their relatively compact internal structure and the inability of individual components to undergo independent small-amplitude vibrations and torsions, are susceptible to damage when used at high altitudes. Under continuous light winds and prolonged minor vibrations, the conductors cannot expand or contract within the overhead line, leading to metal fatigue fractures and contact friction damage to the metal materials. Furthermore, the lack of energy absorption and elastic buffering between internal components causes the overhead line to expand and compress when heated, further increasing frictional losses due to light winds and significantly impacting the lifespan and stability of the overhead line's conductors. Summary of the Invention

When existing overhead power lines are used at high altitudes, the internal structure is relatively compact, and the components cannot undergo independent small-amplitude vibrations and torsions. As a result, under the influence of continuous light winds and long-term small vibrations, the conductors cannot expand and contract within the overhead power line, which easily leads to metal fatigue fracture and contact friction damage to the metal materials.

[0014] According to the above technical solution, one end of the swing cable is inserted into the inner side of the hollow double sleeve, and the longitudinal section of the correction protective pad is arc-shaped.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Equipped with lightweight reinforced vibration damping components, the high-strength lightweight braided rope, pressure-pair friction strips, dense pressure insulating sleeve, and pressure relief holes create a small-amplitude elastic deformation environment for both the inner and outer ends of the battery cell. Combined with insert fixing strips, semi-conductive voltage bands, and high-strength lightweight braided ropes to support and restrict the pressure-pair friction strips and dense pressure insulating sleeve, the battery cell can undergo small-amplitude displacement and elastic expansion. Combined with internal and external bidirectional contact buffering, frictional losses during battery cell oscillation are reduced. Through bidirectional buffering, internal small-space buffering, and friction protection, the simultaneous resonance of multiple internal components during vibration can prevent continuous high-frequency friction, reducing the probability of metal fatigue fracture and frictional losses within the battery cell, and extending the battery cell's service life. By utilizing the bending elastic expansion and contraction of the double-arc pressure block and the outer concave buffer pressure block, and the mutual twisting of the double-arc pressure block and the outer concave buffer pressure block to absorb energy and buffer, the inner convex damping strip and the convex pressure sealing strip are misaligned to absorb energy. Furthermore, by leaving gaps between multiple components, it can effectively expand to both sides during thermal expansion, reducing the pressure on the internal wire core and the probability of small-amplitude vibrations caused by wind, thereby further improving the stability and safety of the overhead line battery core operation. By combining internal and external multi-segment gap expansion and contraction buffers, friction isolation rings, and damping energy absorption buffers, this technology effectively solves the problem in existing technologies where prolonged light winds and the inability of the internal battery cells to effectively expand and contract and buffer against friction lead to continuous deformation and friction of the battery cells, resulting in metal friction loss and metal fatigue fracture. By using gradual buffering from the inside out, the pressure on the battery cells is reduced, while mitigating battery cell friction loss and the occurrence of large-scale external twisting and inward squeezing. Furthermore, the use of multi-component buffering maximizes the buffer space when the overhead line is heated bidirectionally from both inside and outside. Combined with reducing the self-weight of the overhead line, it can slightly increase the sway amplitude in light winds, reducing the occurrence of continuous low-frequency vibrations and further improving the service life and operational stability of the overhead line.

[0016] 2. Equipped with a guiding countermeasure component, which connects the pressure connection plate, bearing connection block, double connection fixing block and overhead line through combination bolts and combination nuts. Combined with limit dampers, swing cables and hollow double sleeves, it uses bidirectional connection limit and segmented damping pull restriction. Combined with the overhead line swinging itself to drive the damper to reciprocate to absorb and release energy, and is synchronously restricted from both sides, so that the overhead line can reduce its actual swing amplitude when affected by strong winds at high altitudes by absorbing energy at both ends. Combined with the inner friction block for relay friction treatment, it reduces the loss of the connection point to the outer insulation components of the overhead line. By using an internal pressure limiting membrane to push the supporting telescopic membrane inward, an uneven structure is formed on the outside of the outer limiting protective elastic sleeve. The non-circular cross-section disrupts the originally smooth laminar boundary layer of the airflow, causing the airflow to become turbulent. This delays the airflow separation point, thereby reducing the pressure difference drag at both ends of the overhead line. Through symmetrical damping energy absorption and release at both ends, multi-segment cable traction, and self-adjusting irregular deformation treatment, the overhead line is externally pulled and limited while the deformation of the overhead line itself controls the pressure difference drag at both ends of the airflow. This significantly reduces the periodic excitation force, suppresses the galloping of the overhead line, and reduces the friction loss at the connection edges of the overhead line. This greatly ensures the stability and safety of the overhead line when used at high altitudes, while also improving the practicality of the overhead line in different operating environments. In summary, by combining lightweight reinforced vibration damping components and guiding and counteracting components, and through internal elastic expansion and contraction buffering, friction reduction treatment, elastic expansion and contraction buffering of each component, and gap treatment, along with external multi-segment traction and the irregular shape of the overhead line that adjusts itself according to wind force, and by utilizing overall weight reduction, the amplitude of overhead line swaying and friction loss of the external insulation layer can be reduced in strong winds, and the internal synchronous vibration and friction loss of the battery cells can be reduced in light winds. This greatly improves the actual operational stability and service life of the overhead line, making it more stable and safer when operating at high altitudes. Attached Figure Description

One end of the combination nut 311 is threadedly connected to a combination bolt 312. The combination bolt 312 is sleeved through and connected to one end of the pressure connecting plate 307, the bearing connecting block 308, the combination locking bracket 309 and the double-connecting fixing block 310, so as to realize through locking and connection limit treatment.

The longitudinal section of the correction protective pad 317 is arc-shaped to ensure a sealed connection and pressure buffer treatment. Several through combination holes 318 are equidistantly opened at the bottom of the bearing joint block 308.

[0022] The working principle and usage process of this invention are as follows: When erecting overhead lines at high altitudes, workers use transportation and traction equipment to pull the overhead lines to the required erection platform. After the overhead lines are pulled to the erection platform, workers attach two inner friction blocks 306 to the outer end of the outer limiting protective elastic sleeve 304, then place two pressure connecting plates 307 on the outer end of the inner friction blocks 306, insert the bearing connecting block 308 between the two pressure connecting plates 307, and snap the combined nut 311 into the inner side of the bearing connecting block 308. The correction protective pad 317 is attached to the bottom of the pressure connecting plate 307 located at the bottom of the outer side of the overhead line. The combined bolt 312 is inserted through and inserted between the pressure connecting plate 307 and the bearing connecting block 308, and the combined bolt 312 and the combined nut 311 are connected by threads to achieve the combined connection of the pressure connecting plate 307, the bearing connecting block 308 and the overhead line. After the bearing-supporting connecting block 308 and the counter-pressure connecting plate 307 are assembled, the staff will perform damping supplementation treatment on the outside of the overhead line according to the wind intensity in the environment where the overhead line is erected. When the wind is strong and frequent, the staff will place the two counter-pressure connecting plates 307 and one double-connection fixing block 310 along the overhead line to the side end of the outer limit protective elastic sleeve 304 on the outside of the overhead line, and use the combination nut 311 and combination bolt 312 to press the counter-pressure connecting plate 307 and double-connection fixing block 310 together. The combination nut 311 and combination bolt 312 are used to connect the combination positioning frame 309 and the bearing connection block 308. After the combination is completed, the limit damper 313 is snapped into the inner side of the combination positioning frame 309 and the double connection fixing block 310. Then, the swing cable 316 is inserted into the inner side of the hollow double sleeve 314, and the combination pin 315 is used to lock and restrict the hollow double sleeve 314 and the swing cable 316 to realize the connection and locking of the swing cable 316. After the overhead line is erected, the lightweight conductive core 207 is combined with the external power connection components to realize power supply. When the overhead line is in use, the strong wind causes the outer limit protective elastic sleeve 304 on the outside of the overhead line to swing. Moreover, the wind is mostly intermittent, causing the overhead line to swing back and forth. During the swinging process, the outer limit protective elastic sleeve 304 drives the inner contact friction block 306 to rotate slightly along the pressure connecting plate 307 and the bearing connecting block 308. Through the small swing friction between the pressure connecting plate 307 and the inner contact friction block 306 and the edge restriction protection treatment of the outer limit protective elastic sleeve 304, the frictional wear of the pressure connecting plate 307 on the outer limit protective elastic sleeve 304 is reduced. Furthermore, the friction damping energy absorption through the pressure connecting plate 307 and the inner friction block 306 reduces the swing amplitude of the overhead line connection point. At the same time, the swing cable 316 pulls the hollow double sleeve 314 and the limiting damper 313. The fixed spacing of the pressure connecting plate 307, the bearing connecting block 308, the combined clamping frame 309 and the double connection fixing block 310 at both ends limits the swing. The energy absorption buffering treatment is carried out in conjunction with the extension and retraction of the limiting damper 313. With the clamping and restriction at both ends, the swing amplitude of the overhead line is reduced and its swing speed is slowed down. At the same time, strong winds blow the outer protective elastic sleeve 304. The inner pressure limiting membrane 305, located at the outer end of the outer protective elastic sleeve 304, is first subjected to wind pressure. This wind pressure pushes the inner pressure limiting membrane 305 to expand elastically inward. The inner pressure limiting membrane 305 also pushes the supporting telescopic membrane 303 to press inward, ultimately pressing it against the side end of the wave spring telescopic plate 302. At this point, a concave structure is formed on the outside of the outer protective elastic sleeve 304. Guided by the outer protective elastic sleeve 304 and the inner pressure limiting membrane 305, the airflow... The unevenness and non-circular cross-section of the overhead line surface disrupt the original smooth laminar boundary layer of the airflow, causing the airflow to separate and form local vortices. This creates turbulence on the uneven outer side of the overhead line and guides the turbulence to flow towards the side end of the overhead line. At this time, the turbulence and the smooth airflow collide, and the turbulent momentum exchange is stronger. The separation point will be delayed, the wake region will be narrowed, the pressure difference drag at both ends of the overhead line will be significantly reduced, and the turbulence generated by the surface irregularity will disrupt the vortex shedding, making the shedding more disordered and greatly reducing the periodic excitation force. In the event of strong winds, the outer protective elastic sleeve 304 pushes inward to support the internal pressure of the telescopic membrane 303, thereby pushing the wave spring telescopic plate 302 to move along the inner convex pressure card slot frame 301, thus buffering the internal pressure limiting membrane 305, avoiding excessive separation that could lead to excessive external deformation and irreversibility, improving the wind and vibration resistance of the overhead line, and ensuring the service life of the overhead line; During the operation of the overhead line, power is transmitted through the lightweight conductive core 207. During the transmission process, because the overhead line is at a high altitude, it is affected by the wind for a long time, causing the overhead line to swing back and forth at a small amplitude. At this time, the components inside the overhead line swing synchronously. However, due to the weight of the components themselves and the gaps between the components inside the overhead line, the components inside the overhead line form swing vibrations of different amplitudes. The high-strength lightweight braided rope 1 located in the center of the interior supports the center of the overhead line. Together with the externally reinforced lightweight braided rope 221, it supports and reinforces the double-concave clamping insulation tube 222 and the separating insulation tube 201 outside the overhead line and limits their load-bearing capacity, ensuring the stability of the internal and external support during the use of the overhead line. At this time, the lightweight conductive core 207 located at the center reciprocates against the pressure-friction strip 206 restricted by the high-strength lightweight braided rope 1 under its own gravity and component force. The deformation of the pressure-friction strip 206 is buffered by the pressure relief hole 211. The insulating flame-retardant tape 208, which is externally pressed and restricted, presses and fixes the lightweight conductive core 207 as a whole. In addition, the tightly pressed insulating sleeve 209 and the pressure relief hole 211 buffer the outside of the lightweight conductive core 207. Through bidirectional buffering, the different vibration amplitudes of the middle of the overhead line, the lightweight conductive core 207, and the outside of the core are prevented from resonating with the internal components, thus reducing the fatigue loss of the core caused by resonance. Meanwhile, the concave buffer sleeve 213 on the outside of the battery cell is steadily engaged with the outside of the semiconducting voltage band 212 under the pressing and limiting action of the elastic opening ring 217 and the elastic pressure limiting ring 216. Multiple double arc pressure sleeves 214 are squeezed and limited by the double clamping action of the group clamping ring 218 and the combined arc clamping ring 219. With the help of the raised pressure sealing band 203, the double arc pressure sleeves 214 are pushed inward to squeeze the concave buffer sleeve 213 under the action of vibration. With the help of the embedded positioning post 215, the concave buffer sleeve 213 and the double arc pressure sleeve 214 are oscillating and limited. With the help of the external inner convex damping strip 202 and the raised pressure sealing band 203, the energy absorption is treated by misalignment damping. Through misalignment damping energy absorption and multi-position reciprocating vibration self-resetting buffer treatment, vibration buffering is achieved. Through multi-segment layer-by-layer uneven vibration treatment from the inside to the outside, the excessive vibration fatigue wear caused by synchronous vibration inside the overhead line is reduced. The lightweight conductive core 207 is isolated and shielded by the internal insulating flame-retardant strip 208 and semi-conductive voltage-binding strip 212. The overhead line is insulated layer by layer with the separation insulating tube 201 and the double-concave locking insulating tube 222. The overall structure is isolated and protected by the outer limiting protective elastic sleeve 304. The internal components are staggered to reduce the internal weight, thereby ensuring the stability and service life of the overhead line during use.
