[0022] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0023] 1. An internal elastic telescopic deformation mechanism is provided. Through the mutual cooperation between the components inside the internal elastic telescopic deformation mechanism, the use process of the cable in a strong wind environment is optimized. Through the dual flexible structure design of the supporting liquid guide box and the limiting liquid capsule, the overall shape of the cable can be adjusted by adjusting the volume of the heat transfer oil inside the supporting liquid guide box and the limiting liquid capsule during use. When the heat transfer oil inside the supporting liquid guide box and the limiting liquid capsule is filled, the cable as a whole can be kept in a cylindrical state. When the cable needs to work in a strong wind environment, the heat transfer oil inside the supporting liquid guide box and the limiting liquid capsule is discharged so that the structure inside the limiting covering sleeve can be changed into a flat state under the action of the elastic clip, thereby effectively reducing the area of ​​the windward surface of the cable, reducing the force area of ​​the cable in a strong wind environment, preventing the cable from shaking violently in a strong wind environment, effectively improving the stability of the cable during operation, preventing the continuous shaking of the cable from accelerating the fatigue aging of the cable connection, extending the service life of the overhead insulated conductor, and effectively improving the environmental adaptability of the cable;

[0024] When it is necessary to adjust the volume of the heat transfer oil in the support liquid guide box and the limit liquid bag by driving the small liquid supply pump to drive the small liquid guide tube and the liquid supply bottom tube, the heat inside the cable can be removed by the reciprocating flow of the heat transfer oil inside the support liquid guide box and the limit liquid bag, thereby realizing rapid cooling of the inside of the cable, thereby effectively improving the heat dissipation efficiency of the cable, ensuring that the inside of the cable can be kept within a suitable range after long-term use, and improving the stability of the internal temperature of the cable after long-term use;

[0025] At the same time, when the cable is squeezed into a circular state by the supporting liquid guiding box and the limiting liquid bag, the elastic expansion and contraction characteristics of the supporting liquid guiding box and the limiting liquid bag are utilized so that the cable can buffer the squeezing through sufficient elastic deformation when subjected to external squeezing, thereby effectively improving the overall anti-squeezing buffering performance of the cable. The mechanical elastic deformation structure of the elastic clip and the flexibly deformable structural characteristics of the limiting coating layer and the deformation protection layer make the cable deformation smoother, effectively avoiding the phenomenon that the cable cannot be recovered after repeated squeezing and deformation, thereby effectively improving the anti-squeezing deformation ability and enhancing the comprehensive structural strength of the cable.

[0026] 2. An outer interactive rotating balancing mechanism is provided. Through the mutual cooperation between the components inside the outer interactive rotating balancing mechanism, the functional buffering process during the use of the cable is optimized. The extrusion liquid capsule can be quickly squeezed through the deformation of the limiting coating layer and the deformation protective layer, so that the shape and position of the rotating light plate and the counterweight magnetic strip are changed through the exchange of the heat transfer oil inside the extrusion liquid capsule and the extrusion flat capsule, so that when strong wind blows over the outside of the cable, the rotating light plate and the counterweight magnetic strip can be driven to rotate quickly, and then the inertia generated during the rotation of the rotating light plate and the counterweight magnetic strip generates traction forces of different directions on the outside of the cable, and the kinetic energy in the airflow outside the cable is consumed by the rotation of the rotating light plate and the counterweight magnetic strip, which further reduces the shaking amplitude of the cable in a strong wind environment and improves the overall stability of the cable during use;

[0027] At the same time, the installation clamp can be quickly installed on the outside of the cable through the cooperation between the installation narrow groove and the installation hoop, which effectively improves the convenience of installation, disassembly and replacement of the installation clamp and its components. When the rotating light plate and the counterweight magnetic strip are in the storage state, the counterweight magnetic strips on the edges of the multiple rotating light plates attract each other and wrap around the outside of the cable, thereby protecting the outside of the cable through the rotating light plate and the counterweight magnetic strip. When the outside of the cable is squeezed, the elastic deformation of the rotating light plate and the counterweight magnetic strip is used to initially buffer the external squeezing, thereby further improving the overall protection performance of the cable outside.

[0028] In summary, through the mutual cooperation between the internal elastic telescopic deformation mechanism and the internal components of the external interactive rotation balancing mechanism, the adaptability of the overhead insulated conductor to the strong wind environment during use is optimized. By deforming the overall shape of the cable, the area of ​​the windward surface of the cable during use can be effectively reduced, so as to directly reduce the blowing effect of strong wind on the cable. The deformation of the limiting coating layer and the deformable protective layer can synchronously drive the rotating light plate and the counterweight magnetic strip to deform, so as to consume the strong wind kinetic energy on the outside of the cable through the rotation of the rotating light plate and the counterweight magnetic strip, and assist in stabilizing the cable through the inertia generated by the rotation of the rotating light plate and the counterweight magnetic strip, thereby further improving the cable's use stability and environmental adaptability.

[0047] A middle liquid guide strip 601 is arranged at the middle position between the multiple center conductors 1 on the inner side of the limiting covering sleeve 5, and a connecting rubber strip 602 is fixedly connected to the end of the middle liquid guide strip 601, and a flat infusion tube 603 is fixedly connected to the middle of the bottom surface of the connecting rubber strip 602, and a supporting liquid guide box 604 is fixedly connected to the end of the flat infusion tube 603 corresponding to the bottom position of the inner side of the limiting covering sleeve 5. The middle part of the inner side of the supporting liquid guide box 604 is filled with an internal supporting cotton strip 605, and small liquid guide tubes 606 are evenly and evenly fixedly connected to the middle of the bottom surface of the supporting liquid guide box 604. The bottom ends of the multiple small liquid guide tubes 606 are commonly fixedly connected to a liquid supply bottom tube 607, and the end of the liquid supply bottom tube 607 is fixedly connected to a small liquid supply pump 608. The top two ends of the middle liquid guide strip 601 A liquid-distributing flat tube 609 is fixedly connected at the middle position of the side, and a limiting liquid capsule 610 is fixedly connected to the end of the liquid-distributing flat tube 609 at a position corresponding to the inner position of the limiting covering sleeve 5. The ends of two adjacent middle liquid-conducting strips 601 are connected by connecting rubber strips 602. The middle liquid-conducting strip 601 is connected to the supporting liquid-conducting box 604 and the limiting liquid capsule 610 through the infusion flat tube 603 and the liquid-distributing flat tube 609. The middle liquid-conducting strip 601, the supporting liquid-conducting box 604 and the limiting liquid capsule 610 can be elastically compressed and deformed after being squeezed, and the supporting liquid-conducting box 604 and the limiting liquid capsule 610 are tightly fitted to the outer side of the protective outer layer 4 after the inside of the supporting liquid-conducting box 604 and the limiting liquid capsule 610 are filled with heat-conducting oil.

[0048] The outer side of the limiting covering sleeve 5 is evenly and equidistantly clamped with elastic clips 611, and the outer side of the limiting covering sleeve 5 is tightly covered with a limiting covering layer 612 corresponding to the outer side of the elastic clip 611, and the outer side of the limiting covering layer 612 is tightly covered with a deformation protection layer 613, and the limiting covering layer 612 and the deformation protection layer 613 are both made of flexible materials, and deformation channels are evenly opened inside the deformation protection layer 613, and the bottom of the deformation protection layer 613 corresponds to the outer side of the liquid supply bottom tube 607. The end of the liquid supply small pump 608 is connected to the external liquid supply pipeline through a pipeline, and the inner side of the limiting clip 614 is tightly fitted with the outer side of the liquid supply bottom tube 607, and the outer side of the limiting clip 614 is flush with the outer side of the deformation protection layer 613. The mutual cooperation between the components inside the internal elastic telescopic deformation mechanism 6 optimizes the use of the cable in a strong wind environment. The double flexible structure design of the capsule 610 allows the shape of the entire cable to be adjusted by adjusting the volume of the heat transfer oil in the supporting liquid guide box 604 and the limiting liquid capsule 610 during use. When the heat transfer oil in the supporting liquid guide box 604 and the limiting liquid capsule 610 is filled, the cable as a whole can be kept in a cylindrical state. When the cable is required to work in a strong wind environment, the heat transfer oil in the supporting liquid guide box 604 and the limiting liquid capsule 610 is discharged so that the structure inside the limiting covering sleeve 5 can be flattened under the action of the elastic clamping strip 611, thereby effectively reducing the area of ​​the windward surface of the cable, reducing the force area of ​​the cable in a strong wind environment, preventing the cable from shaking violently in a strong wind environment, effectively improving the stability of the cable during operation, preventing the continuous shaking of the cable from accelerating fatigue aging at the cable connection, extending the service life of the overhead insulated conductor, and effectively improving the environmental adaptability of the cable.

[0049] When it is necessary to adjust the volume of the heat transfer oil inside the supporting liquid guide box 604 and the limiting liquid capsule 610 by driving the liquid supply small pump 608 to drive the liquid guide small tube 606 and the liquid supply bottom tube 607, the heat inside the cable can be removed by the reciprocating flow of the heat transfer oil inside the supporting liquid guide box 604 and the limiting liquid capsule 610, thereby realizing rapid cooling of the inside of the cable, thereby effectively improving the heat dissipation efficiency of the cable, ensuring that the inside of the cable can be kept within a suitable range after long-term use, and improving the stability of the internal temperature of the cable after long-term use;

[0050] At the same time, when the cable is squeezed into a circular state by the supporting liquid guide box 604 and the limiting liquid capsule 610, the elastic expansion and contraction characteristics of the supporting liquid guide box 604 and the limiting liquid capsule 610 are utilized, so that when the cable is squeezed from the outside, the squeezing can be buffered by sufficient elastic deformation, thereby effectively improving the overall anti-squeezing buffering performance of the cable, and the mechanical elastic deformation structure of the elastic clip 611 and the flexibly deformable structural characteristics of the limiting coating layer 612 and the deformation protection layer 613 make the cable deformation more smooth, effectively avoiding the phenomenon that the cable cannot be restored after repeated squeezing and deformation, thereby effectively improving the anti-squeezing deformation ability and improving the comprehensive structural strength of the cable;

[0051] An outer interactive rotation balancing mechanism 7 is arranged outside the deformation protection layer 613, and the outer interactive rotation balancing mechanism 7 is used to protect the outer side of the cable and guide and buffer the airflow blowing to the outer side of the cable through deformation during the use of the cable;

[0052] The outer interactive rotating balancing mechanism 7 includes a mounting snap ring 701, a mounting narrow groove 702, a driving wide groove 703, a mounting hoop 704, an extruding liquid capsule 705, a liquid guiding tube 706, an extruding flat capsule 707, a mounting arc block 708, a protective arc block 709, a rotating light plate 710, a counterweight magnetic strip 711 and a limiting collar 712;

[0053] The deformation protection layer 613 is symmetrically clamped with a mounting clamp ring 701 on the outside, a mounting narrow groove 702 is provided on one side of the mounting clamp ring 701, a driving wide groove 703 is provided on the other side of the mounting clamp ring 701, and a mounting hoop ring 704 is fixedly clamped in both mounting narrow grooves 702;

[0054] An extrusion sac 705 is bonded to the middle of the inner arc surface of the mounting clamp 701 corresponding to the outer position of the deformation protection layer 613. The extrusion sac 705 is filled with heat transfer oil, and the inner arc surface of the extrusion sac 705 is tightly fitted to the outer position of the deformation protection layer 613.

[0055] The middle parts of both ends of the extrusion liquid capsule 705 are fixedly connected with a liquid guiding tube 706, and the end of the liquid guiding tube 706 is fixedly connected with an extrusion flat capsule 707 at a position corresponding to the inner part of the driving wide groove 703. The outer side of the extrusion flat capsule 707 is tightly fitted with the inner wall of the driving wide groove 703, and the extrusion flat capsule 707 can be elastically expanded and retracted during use;

[0056] The outer arc surface of the extruded flat capsule 707 is evenly and evenly bonded with mounting arc blocks 708, and the inner arc surface of the mounting clamp 701 is bonded with a protective arc block 709 at a position corresponding to the outer side of the liquid guiding tube 706. The inner arc surface of the protective arc block 709 is tightly fitted with the outer side of the deformation protection layer 613, and the extruded liquid capsule 705 is connected with the inner cavity of the extruded flat capsule 707 through the liquid guiding tube 706.

[0057] A rotating light plate 710 is rotatably installed between the ends of two adjacent arc-shaped mounting blocks 708 via a rotating shaft, and weighted magnetic strips 711 are bonded to the edges of both sides of the rotating light plate 710. The side of the mounting clamp 701 is tightly covered with a limiting collar 712 at a position corresponding to the outer side of the deformation protection layer 613, and the side of the driving wide groove 703 is evenly and equidistantly provided with arc grooves at a position corresponding to one side of the rotating light plate 710. The weighted magnetic strips 711 on the sides of the two adjacent rotating light plates 710 are attracted to each other by magnetic force, and the functional buffering process during the use of the cable is optimized through the mutual cooperation between the internal components of the external interactive rotating balancing mechanism 7, and the deformation of the limiting coating layer 612 and the deformation protection layer 613 can be The extrusion liquid capsule 705 is quickly squeezed, so that the shape and position of the rotating light plate 710 and the counterweight magnetic strip 711 are changed through the exchange of the heat transfer oil inside the extrusion liquid capsule 705 and the extrusion flat capsule 707, so that when strong wind blows over the outside of the cable, the rotating light plate 710 and the counterweight magnetic strip 711 can be driven to rotate quickly, and then the inertia generated during the rotation of the rotating light plate 710 and the counterweight magnetic strip 711 generates traction forces of different directions on the outside of the cable, and the rotation of the rotating light plate 710 and the counterweight magnetic strip 711 consumes the kinetic energy of the airflow outside the cable, further reducing the shaking amplitude of the cable in a strong wind environment and improving the overall stability of the cable during use;

[0058] At the same time, the installation clamp 701 is quickly installed on the outside of the cable through the mutual cooperation between the installation narrow groove 702 and the installation hoop 704, which effectively improves the convenience of installation, disassembly and replacement of the installation clamp 701 and its components. When the rotating light plate 710 and the counterweight magnetic strip 711 are in the storage state, the counterweight magnetic strips 711 on the edges of the multiple rotating light plates 710 attract each other and wrap around the outside of the cable, thereby protecting the outside of the cable through the rotating light plate 710 and the counterweight magnetic strip 711, and when the outside of the cable is squeezed, the elastic deformation of the rotating light plate 710 and the counterweight magnetic strip 711 is used to initially buffer the external squeezing, thereby further improving the overall protection performance of the cable outside.

[0059] Working principle and use process of the present invention: In the actual application process of the present invention, during the installation and use of the overhead insulated conductor, it is necessary to first connect the cable to a suitable position, then guide the current through the central conductor 1, and then shield the outer side of the central conductor 1 through the conductor inner shield 2 to reduce the interference of the external environment on the inside of the cable, and protect the cable through the protective outer layer 4 to further improve the protection performance of the cable, and then bundle and limit the multiple central conductors 1 through the limiting covering sleeve 5, so that the central conductor 1 can only move within a suitable range during use;

[0060] When the cable is blown by strong winds from outside and the overall shape of the cable needs to be adjusted, the end of the liquid supply bottom pipe 607 needs to be connected to the external liquid supply pipeline first, and then the flow direction of the heat transfer oil inside the liquid supply bottom pipe 607 is adjusted by the operation of the liquid supply small pump 608. When the overall shape of the cable needs to be kept round, the liquid supply small pump 608 can be used to cooperate with the liquid guide small pipe 606 and the liquid supply bottom pipe 607 to fill the support liquid guide box 604 and the limit liquid bag 610 with heat transfer oil, so that the support liquid guide box 604 and the limit liquid bag 610 can be kept round. The positioning liquid capsule 610 can be expanded under the action of hydraulic pressure. At the same time, since the supporting liquid guiding box 604 and the limiting liquid capsule 610 are connected through the middle liquid guiding strip 601, the infusion flat tube 603 and the liquid separation flat tube 609, it is ensured that the expansion degree of the supporting liquid guiding box 604 and the limiting liquid capsule 610 is consistent, and then through the squeezing of the supporting liquid guiding box 604 and the limiting liquid capsule 610, the positions of the multiple center conductors 1 are kept equidistantly distributed in the circumference, so as to ensure that the overall shape of the cable can be kept cylindrical during use;

[0061] After the heat transfer oil in the support liquid guide box 604 and the limiting liquid capsule 610 is sucked by the liquid supply small pump 608, the support liquid guide box 604 and the limiting liquid capsule 610 will shrink quickly as the heat transfer oil inside them is discharged. At this time, a gap will appear inside the limiting coating sleeve 5 due to the loss of the filling of the support liquid guide box 604 and the limiting liquid capsule 610. Then, the two mutually buckled elastic clips 611 will continue to approach each other under the action of their own elastic force, and then the elastic clips 611 realize the extrusion between the components inside the limiting coating sleeve 5, so that the multiple central conductors 1 distributed in a circle will gradually approach and become parallel. In the deformation process of the elastic clips 611, the limiting coating layer 612 and the deformation protection layer 613 will also be synchronously squeezed to deform synchronously, so that the cable as a whole becomes flat to reduce the area of ​​the windward surface of the cable, and then the connection between the liquid supply bottom pipe 607 and the deformation protection layer 613 is sealed by the limiting clip 614 to improve the overall sealing of the cable.

[0062] When the cable is deformed and becomes flat, the installation clamp ring 701 and the components thereon are clamped to the outside of the cable through the cooperation between the installation narrow groove 702 and the installation hoop ring 704, and the axial position of the installation clamp ring 701 is limited by the limiting ring 712 sleeved on the outside of the cable. The extrusion liquid capsule 705 can be squeezed by the deformation of the limiting coating layer 612 and the deformation protection layer 613, so that the heat transfer oil inside the extrusion liquid capsule 705 is introduced into the extrusion flat capsule 707 through the liquid guide tube 706, and as the heat transfer oil inside the extrusion flat capsule 707 increases, the extrusion flat capsule 707 is 707 drives the installation arc block 708 to move outward along the cable axis, and then drives the rotating light plate 710 to move outward along the cable axis through the movement of the protective arc block 709, so that the counterweight magnetic strips 711 on the sides of two adjacent rotating light plates 710 are separated from each other, thereby canceling the limit of the rotating light plate 710, so that the rotating light plate 710 rotates driven by the airflow outside the cable, and the inertia generated during the rotation of the rotating light plate 710 and the counterweight magnetic strip 711 is used to balance the overall movement state of the cable, so as to prevent the cable from shaking significantly under the blowing of strong wind;

[0063] The outer side of the liquid guiding tube 706 is protected by the protective arc block 709 to prevent the liquid guiding tube 706 from being damaged by the external environment during the use of the cable. At the same time, the limiting ring 712 limits the installation clamp 701, so that the overall structure can be more stable after the installation clamp 701 is installed.
