[0002] Iron accessories for power transmission towers refer to various metal components used to support, fix, and connect the tower structure and transmission lines. They are usually made of steel materials such as angle steel, flat iron, and channel steel, and are treated with anti-corrosion treatment such as hot-dip galvanizing. They are an indispensable part of the tower and are widely used in transmission lines from 10kV to 220kV and above. A Chinese patent discloses an easy-to-fix assembled power iron accessory, application number CN202510003242.4. This patent solves the problem of loosening and detachment caused by rust at the contact point between the iron accessory and the power pole due to the external environment. It also uses elastic support to reduce rigid deformation damage caused by swaying, effectively improving the stability and service life of the equipment and reducing the impact of the external environment on the equipment. However, the current use of iron accessories is limited by the connection method, which means that the cable and the iron accessory are connected in a fixed way. When the cable is blown by external airflow during use, it will shake to varying degrees. The force generated by the cable shaking will directly act on the connection on the iron accessory, which will cause the connection between the cable and the iron accessory to loosen, thus reducing the installation stability and environmental adaptability of the iron accessory.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. A linkage-type symmetrical buffer and stabilizing mechanism is set up. Through the cooperation of the internal components of the linkage-type symmetrical buffer and stabilizing mechanism, the installation and protection process of the iron accessories is optimized. Through the symmetrical linkage limit tilting arc-shaped clamping block structure design, the kinetic energy of the cable swaying process is transmitted through the cooperation between the front drive gear, the lower transmission gear, the upper transmission gear, and the translational transmission rack. This prevents the force generated by the cable swaying under the action of airflow from directly acting on the connection between the cable and the iron accessories, effectively preventing the iron accessories from being damaged by cable swaying during use. Furthermore, through the synchronous swing of the symmetrically distributed limit tilting arc-shaped clamping blocks, the kinetic energy of the cable swaying process can be consumed by the limit tilting arc-shaped clamping blocks. At the same time, the kinetic energy of the limit tilting arc-shaped clamping blocks during the reset process can collide and cancel out the kinetic energy of the cable during the reverse swaying process, which effectively reduces the swaying amplitude of the cable under strong winds and further improves the safety of the iron accessories. Meanwhile, under the swinging action of the inclined arc-shaped clamping block, the lifting and limiting arc-shaped block can also swing downward through the transmission sliding rack and deflection drive gear. Utilizing the elastic deformable characteristics of the buffer connecting rubber seat, the lifting and limiting arc-shaped block can also make slight swinging deviations during the cable swinging process, thereby effectively improving the fit between the lifting and limiting arc-shaped block and the cable. Furthermore, during the collision between the inclined arc-shaped clamping block and the lifting and limiting arc-shaped block and the cable, the outer side of the cable will vibrate. This vibration removes ice and snow from the outer side of the cable, further expanding the function of the iron accessories, improving their environmental adaptability, and ensuring good performance even in cold weather. Furthermore, the vibration drive motor can drive the lifting and limiting arc block to swing actively, and during the swing of the lifting and limiting arc block, it can drive the limiting tilting arc clamp block to swing synchronously, so as to ensure that the iron accessory can remove the ice shell and snow on the outside of the cable by knocking even in windless weather. At the same time, through the cooperation between the buffer rubber sleeve and the various components on it, the cable end is provided with auxiliary support and the cable sliding and vibration are intercepted, which further improves the stability of the cable installation on the iron accessory.

[0015] 2. An external temperature control and circulation adjustment mechanism is set up. Through the cooperation of the various components inside the external temperature control and circulation adjustment mechanism, the environmental adaptability of the iron accessories is optimized. Through the cooperation of the various components inside the central rectangular box, hot air can be continuously blown into the outer protective box in cold weather, thereby effectively preventing the gear components inside the outer protective box from jamming due to rain and freezing. This ensures that the various components inside the outer protective box can be maintained within a suitable temperature range in cold weather. At the same time, through the cooperation of the various components between the front heat conduction liquid box and the telescopic liquid bladder, the airflow rate blown out from both sides of the inner box of the protective rectangle is automatically adjusted, thereby effectively improving the environmental adaptability of the iron accessories. Simultaneously, through the cooperation of various components connected between the blowing regulating valve and the blowing ring box, the hot airflow inside the protective rectangular inner box is directionally guided, so that the hot airflow inside the central rectangular box can perform auxiliary heating and cleaning on the outside of the cable, allowing the ice shell and snow adhering to the outside of the cable to melt and fall off. This further expands the function of the iron accessories, enabling the iron accessories to actively clean the snow on the outside of the cable in cold weather, thereby effectively improving the connection stress between the cable and the iron accessories.

[0016] In summary, through the coordinated operation of the components within the linkage-type symmetrical buffer stabilization mechanism and the external temperature control and circulation adjustment mechanism, the kinetic energy during cable swaying is buffered by the transmission and swing of the limiting inclined arc-shaped clamp and the lifting limiting arc-shaped block. The kinetic energy during cable swaying is circulated and converted by the iron accessories, effectively preventing loosening and fatigue damage at the connection between the cable and the iron accessories. This improves the service life and installation stability of the iron accessories. Furthermore, the iron accessories can actively tap the outside of the cable and actively blow hot air onto the outside of the cable, effectively expanding the functionality of the iron accessories. In cold weather, the iron accessories can actively clear ice and snow from the outside of the cable, thus effectively improving the environmental adaptability of the iron accessories.

A blowing regulating valve 517 is embedded in the center of the top of the protective rectangular inner box 505. A guide tube 518 is fixedly connected to the center of the top of the blowing regulating valve 517. A diversion box 519 is fixedly connected to the top of the guide tube 518 at the position corresponding to the outer side of the cable. Blowing tubes 520 are fixedly connected to both ends of the top of the diversion box 519. A blowing ring box 521 is fixedly connected to the end of the blowing tube 520 at the position corresponding to the outer side of the cable. The diversion box 519 and the blowing ring box 521 are interconnected. A blowing circular groove is opened at the end of the blowing ring box 521, and a conical guide ring is fixedly connected to the end of the blowing ring box 521. The internal components of the external temperature control and circulation regulating mechanism 5 are adjusted accordingly. The mutual cooperation between the components optimizes the environmental adaptability of the iron accessories. Through the mutual cooperation between the components inside the central rectangular box 502, hot air can be continuously blown into the outer protective box 426 in cold weather, thereby effectively preventing the gear components inside the outer protective box 426 from jamming due to rain and freezing. This ensures that the components inside the outer protective box 426 can also be kept within a suitable temperature range in cold weather. At the same time, through the mutual cooperation between the components between the front heat-conducting liquid box 511 and the telescopic liquid bladder 514, the airflow rate blown out from both sides of the inner protective rectangular box 505 is automatically adjusted, thereby effectively improving the environmental adaptability of the iron accessories. Simultaneously, through the cooperation of the various components connected between the blowing regulating valve 517 and the blowing annular box 521, the hot airflow inside the protective rectangular inner box 505 is directionally guided, so that the hot airflow inside the central rectangular box 502 can perform auxiliary heating and cleaning on the outside of the cable, so that the ice shell and snow adhering to the outside of the cable can melt and fall off, further expanding the function of the iron accessories, enabling the iron accessories to actively clean the snow on the outside of the cable in cold weather, thereby effectively improving the connection stress between the cable and the iron accessories.

[0021] The working principle and usage process of this invention: In the actual application of this invention, when iron accessories are required, the installation crossbeam 2 and its components are first installed on the power tower at a suitable position through the central installation column 1. Then, the corresponding cable is supported and fixed by the insulating support seat 3 at the top of the installation crossbeam 2 to realize the installation of the iron accessories. Then, the connecting side suspension rod 402 and its components are installed on the side of the mounting frame 2 through the connecting bracket 401. When the cable is blown by a strong airflow and shakes, the shaking of the cable causes the limiting tilting arc-shaped clamp 406 to swing to one side. Then, the swing of the limiting tilting arc-shaped clamp 406 causes the horizontal swinging side bending rod 404 and the transmission reinforcing rod 405 to swing synchronously. Then, the swing of the horizontal swinging side bending rod 404 causes the swinging side circular block 403 to rotate, and during the rotation of the swinging side circular block 403, the front drive gear 407 is driven to rotate. The front drive gear 407 rotates, which drives the lower transmission gear 408 at the bottom of the arc-shaped suspension plate 427 to rotate synchronously. During the rotation of the lower transmission gear 408, the upper transmission gear 409 is driven to rotate synchronously. Then, the rotation of the upper transmission gear 409 drives the translational transmission rack 410 to move along the bottom of the connecting side suspension rod 402. During the sliding of the connecting side suspension rod 402 on one side, the central connecting suspension rod 411 drives the translational transmission rack 410 on the other side to slide synchronously. When the two translational transmission racks 410 slide synchronously, the buffer return spring 412 can be compressed and stored through the central connecting suspension rod 411. During the sliding process of the translational transmission rack 410 on the other side, the corresponding gear set at the bottom of the arc-shaped suspension plate 427 and the connecting side suspension rod 402 drives the horizontal swinging side bending rod 404 on the other side to swing. During the swinging process of the horizontal swinging side bending rod 404, the corresponding limiting inclined arc-shaped clamp 406 is simultaneously driven to swing outward. Thus, through the transmission of the gear set, the compression of the buffer return spring 412 and the swinging of the limiting inclined arc-shaped clamp 406 on the other side, the kinetic energy of the cable swing is consumed, thereby reducing the force on the connection between the insulation support 3 and the cable during the cable swing. Meanwhile, when the cable swings back after reaching its highest point, the buffer reset spring 412 extends and resets, driving the translational transmission rack 410 to reset synchronously. During the reset process of the translational transmission rack 410, the two limiting inclined arc-shaped clamps 406 are simultaneously reset to the center. This allows the cable to make opposing contact with the simultaneously reset limiting inclined arc-shaped clamps 406 during the reverse swing process. This allows the kinetic energy of the limiting inclined arc-shaped clamps 406 and the cable to cancel each other out during the collision, thereby reducing the amplitude of the cable's sway. Simultaneously, as the central connecting suspension rod 411 slides, it drives the transmission sliding rack 414 to slide horizontally. During the sliding of the transmission sliding rack 414, it drives the deflection drive gear 417 at the bottom of the mounting side suspension rod 415 to rotate. During the rotation of the deflection drive gear 417, it drives the swing lifting rod 418 to swing. During the swing of the swing lifting rod 418, it drives the buffer connecting rubber seat 419 and the lifting limiting arc block 420 to swing upward. Then, during the swing of the limiting inclined arc clamp 406 towards both sides of the cable, the lifting limiting arc block 420 lifts the cable upward. The lifting of the lifting limiting arc block 420 improves the stress condition at the cable end connection, avoids the force of the cable swinging process from directly acting on the connection between the cable and the insulation support seat 3, and further improves the stability of the cable installation. The oscillation drive motor 416 can drive the lifting and limiting arc block 420 to swing actively, and during the swing of the lifting and limiting arc block 420, it can drive the limiting tilting arc clamp 406 to swing synchronously, so as to ensure that the iron accessories can remove the ice shell and snow on the outside of the cable by knocking even in windless weather. At the same time, through the cooperation between the buffer rubber sleeve 425 and its components, the cable end is provided with auxiliary support and the cable sliding and vibration are intercepted. The height of the supporting arc-shaped clamp 423 is adjusted by the telescopic adjustment between the supporting guide seat 421 and the lifting sliding rod 422. The buffer rubber sleeve 425 is clamped and fixed by the supporting arc-shaped clamp 423 and the limiting arc-shaped pressure plate 424. The height of the buffer rubber sleeve 425 is adjusted by the lifting and lowering of the lifting sliding rod 422. The height of the cable is adjusted by the adjustment of the buffer rubber sleeve 425. This ensures that the cable can be continuously kept in the side area of ​​the limiting tilting arc-shaped clamp 406 and the lifting limiting arc-shaped block 420 during use, ensuring the stability of the cable during use and installation. When it is necessary to adjust the heat preservation of iron accessories in cold weather, the central rectangular box 502 is installed on the side of the outer protective box 426 by connecting the mounting plate 501, and the end of the central rectangular box 502 is sealed by the rubber connecting sleeve 504 to ensure that the airflow inside the central rectangular box 502 can be smoothly introduced into the outer protective box 426. When it is necessary to prevent the gear set inside the outer protective box 426 from freezing and jamming in cold weather, the circulating blower 509 inside the circular mounting box 506 continuously introduces external airflow into the inner protective rectangular box 505, and the bottom of the circular mounting box 506 is isolated and protected by the guide protective circular plate 507 and the dustproof arc sleeve 508, effectively preventing external dust from being sucked into the central rectangular box 502. Furthermore, when the airflow passes through the inner protective rectangular box 505, the airflow is heated by the internal heating mesh 510, and then guided by the air guide rectangular groove at the end of the inner protective rectangular box 505. The hot airflow enters the outer protective box 426 through the rubber connecting sleeve 504, and the temperature inside the outer protective box 426 is maintained by the hot airflow, preventing the gear set inside the outer protective box 426 from freezing and jamming, effectively improving the environmental adaptability of the iron accessories. As the hot air flows through the outside of the front heat transfer fluid box 511, it heats the heat transfer oil inside. When the temperature of the heat transfer oil inside the front heat transfer fluid box 511 rises, it naturally expands. Then, the expanded heat transfer oil is guided through the guide tube 512 and the telescopic flat box 513. During the expansion of the heat transfer oil, the telescopic liquid bladder 514 expands downward. During the expansion of the telescopic liquid bladder 514, the lifting and sealing slide plate 515 moves downward against the elasticity of the support and reset spring 516. The lowered lifting and sealing slide plate 515 seals the rectangular air guide groove at the end of the protective rectangular inner box 505, thereby realizing the automatic adjustment of the air flow at the end of the protective rectangular inner box 505. When hot air is needed to blow away the frost on the outside of the cable, the hot air inside the protective rectangular inner box 505 is introduced into the guide tube 518 through the blowing regulating valve 517. Then, the hot air inside the guide tube 518 is introduced into the blowing tube 520 through the diversion box 519. The air inside the blowing tube 520 is blown towards the outside of the cable through the blowing ring box 521. The hot air generated by the blowing ring box 521 continuously heats and defrosts the outside of the cable, effectively expanding the function of the iron accessories and improving their environmental adaptability.
