[0023] 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:

[0024] 1. An outer flexible telescopic protective mechanism is provided. Through the mutual cooperation between the components inside the outer flexible telescopic protective mechanism, the outer protection and cleaning process of the cable is optimized. By driving the air pump to alternately squeeze the extruded arc bag, the heat transfer oil inside the extruded arc bag can be alternately rushed into the inner telescopic groove and the outer telescopic groove. The elasticity and elasticity between the protective inner film and the protective outer film and the mutual adsorption between the limit magnetic strips are utilized to make the protective inner film and the protective outer film quickly squeeze and expand the protective outer layer at the moment of separation, and at the same time drive the cable to perform high-frequency micro-swing, and then utilize the inertia generated during the deformation and shaking of the outer side of the cable to accelerate the separation of the corrosive solution on the outer side of the cable, remove the corrosive solution generated by the mixture of rainwater and dirt that adheres to the outer side of the cable for a long time and causes corrosion damage to the cable, effectively reduce the aging rate of the cable, and extend the service life of the cable;

[0025] At the same time, when it is necessary to clean the thin ice condensed on the outside of the cable in cold weather, the arc-shaped capsule can be squeezed continuously to make the protective inner film and the protective outer film expand continuously to increase the outer diameter of the cable, so that the thin ice attached to the outside of the protective outer layer is squeezed and broken and falls off naturally. When the ice layer condensed in a local area of ​​the cable is too thick and needs to be knocked and cleaned, the heat transfer oil filled in the telescopic inner groove and the telescopic outer groove can also protect the outside of the cable, effectively preventing the cleaning personnel from damaging the inside of the cable during the knocking process, thereby effectively improving the overall protection performance of the cable and improving the cable's adaptability to the environment;

[0026] At the same time, the bottom of the cable is supplemented with support by the traction line and the limiting triangle plate, which effectively improves the stress condition of the cable after installation. The traction line shares part of the gravity on the cable, and the bottom of the cable is limited by the traction line to reduce the amplitude of the cable shaking in the wind, thereby effectively slowing down the fatigue wear rate of the cable connection, improving the stability of the cable installation, and further effectively improving the service life of the cable.

[0027] 2. An internal extrusion heat conduction circulation mechanism is provided. The heat conduction process inside the cable is optimized through the mutual cooperation between the components inside the internal extrusion heat conduction circulation mechanism. The volume of the heat conduction oil inside the arc-shaped extrusion inner box can also be adjusted synchronously by extruding the arc-shaped capsule, and the extrusion sleeve is driven to alternately extrude the inside of the internal heat-absorbing wide strip through the change of the heat conduction oil volume, and then the internal heat-absorbing wide strip and the heat conduction oil inside the circulation narrow strip are driven to exchange through the expansion and contraction of the extrusion sleeve, and the heat exchange inside and outside the cable is realized during the heat conduction oil exchange process. In the heat exchange process, the expansion of the circulation narrow strip can be used to exchange heat with the heat conduction oil outside the protective inner film. By improving the heat dissipation process inside the cable, the heat dissipation efficiency inside the cable is improved, so that the cable can be kept within a suitable temperature range under high load, thereby effectively improving the overall performance of the cable;

[0028] At the same time, the outer side of the central conductor is flexibly limited by the internal heat-absorbing wide strip and the circulating narrow strip, so that the cable can undergo a larger range of elastic deformation when squeezed, thereby effectively improving the cable's anti-extrusion ability and the overall strength of the cable;

[0029] In summary, through the mutual cooperation between the outer flexible telescopic protection mechanism and the internal extrusion heat conduction circulation mechanism, the internal structures of the cable are actively controlled by alternatingly squeezing the extruded arc capsules, and by controlling the volume of the heat transfer oil between the protective inner film and the protective outer film, the corrosive solution and thin ice on the outside of the cable are cleaned, and the outside of the cable is protected by the heat transfer oil to prevent the cable from being damaged during external impact. When the extruded arc capsule is squeezed, the efficiency of internal and external heat exchange of the cable can be assisted, thereby effectively improving the heat dissipation process of the cable, so that the cable can be continuously maintained in a suitable temperature range under high load, thereby improving the comprehensive performance of the cable.

The end of the traction line 717 is fixedly connected to the connecting frame, and the traction line 717 remains taut after the cable is installed. The mutual cooperation between the internal components of the outer flexible telescopic protective mechanism 7 optimizes the electrical During the cable outer protection and cleaning process, the air pump 716 is driven to alternately squeeze the extrusion arc bag 710, so that the heat transfer oil inside the extrusion arc bag 710 can be alternately rushed into the telescopic inner groove 702 and the telescopic outer groove 704, and the elastic expansion and contraction characteristics between the protective inner film 701 and the protective outer film 703 and the mutual adsorption characteristics between the limiting magnetic strips 705 are utilized to make the protective inner film 701 and the protective outer film 703 quickly squeeze and expand the protective outer layer 9 at the moment of separation, and at the same time drive the cable to perform high-frequency micro-swing, and then utilize the inertia generated during the deformation and shaking of the outer side of the cable to accelerate the separation of the corrosive solution on the outer side of the cable, remove the corrosive solution generated by the mixture of rainwater and dirt that has been attached to the outer side of the cable for a long time and causes corrosion damage to the cable, effectively reduce the aging rate of the cable, and extend the service life of the cable;

[0059] An internal heat absorbing wide strip 805 is provided on one side of the arc-shaped extruded inner box 801, and the ends of the internal heat absorbing wide strip 805 are fixedly connected with liquid guiding inclined tubes 806 at equal distances on both sides, and the ends of the liquid guiding inclined tubes 806 are fixedly connected with circulation narrow strips 807 at the positions on both sides of the internal heat absorbing wide strip 805, and the tops of the two circulation narrow strips 807 and the internal heat absorbing wide strip 805 are fixedly connected with flow guiding arc-shaped tubes 808, and one end of the internal heat absorbing wide strip 805 is bonded with an isolation The elastic cover 809, the outer side of the internal heat absorbing wide strip 805 corresponding to the position between the internal heat absorbing wide strip 805 and the circulation narrow strip 807 is filled with a fan-shaped strip 810, the internal heat absorbing wide strip 805 and the inner cavity of the liquid guiding inclined tube 806 are connected to each other through the guiding arc tube 808, and the inner cavity of the internal heat absorbing wide strip 805 and the circulation narrow strip 807 are filled with heat transfer oil, the inner wall of the isolation elastic cover 809 is tightly fitted with the outer side of the extrusion sleeve 803, and the outer guide groove of the fan-shaped strip 810 is connected to the inner guide groove of the inner guide groove. The wide heat-absorbing strip 805 fits tightly with the outer side of the narrow circulation strip 807. The internal components of the internal extrusion heat-conducting circulation mechanism 8 cooperate with each other to optimize the heat conduction process inside the cable. The volume of the heat-conducting oil inside the arc-shaped extrusion inner box 801 can also be adjusted synchronously by extruding the arc-shaped capsule 710, and the extrusion sleeve 803 is driven to alternately extrude the inside of the wide heat-absorbing strip 805 through the change of the volume of the heat-conducting oil. Then, the expansion of the extrusion sleeve 803 drives the internal heat-absorbing strip 805 and the heat-conducting oil inside the narrow circulation strip 807 to exchange, and the heat exchange between the inside and outside of the cable is realized during the heat exchange process. In the process of heat exchange, the expansion of the narrow circulation strip 807 can be used to exchange heat with the heat-conducting oil outside the protective inner film 701. By improving the heat dissipation process inside the cable, the heat dissipation efficiency inside the cable is improved, so that the cable can be kept within a suitable temperature range even under high load, thereby effectively improving the overall performance of the cable.

[0060] At the same time, the outer side of the central conductor 1 is flexibly limited by the internal heat-absorbing wide strip 805 and the circulating narrow strip 807, so that the cable can undergo a larger range of elastic deformation when squeezed, thereby effectively improving the cable's anti-extrusion ability and the overall strength of the cable.

[0061] The working principle and use process of the present invention: During the use of the cable, the present invention needs to first install the cable to a suitable position, install the traction line 717 to a suitable position, and use the traction line 717 to cooperate with the limiting triangle plate 718 to assist in the installation and positioning of the driving air pipe 715, and then during the normal use of the cable, conduct the current through the central conductor 1, and then protect the outer side of the central conductor 1 through the conductor shield 2, the insulating layer 3 and the metal shield 4, and limit the position of multiple conductors through the flexible constraint layer 5, and then assist in supporting the multiple conductors through the central support bar 6, so that the relative positions of the multiple central conductors 1 are maintained;

[0062] When it is necessary to clean the outside of the cable, the driving air pump 716 is used to alternately supply air to the driving air pipe 715, and then the driving air pipe 715 is used to adjust the air pressure inside the chamber composed of the telescopic sleeve 713 and the extrusion top plate 714. As the air pressure inside the telescopic sleeve 713 rises, the extrusion top plate 714 can be driven to squeeze the extrusion arc bag 710. When the extrusion arc bag 710 is squeezed, the heat transfer oil inside it will enter the arc-shaped liquid guide box 708 through the liquid guide flat tube 709, and then the heat transfer oil inside the arc-shaped liquid guide box 708 will be introduced into the chamber composed of the telescopic inner groove 702 and the telescopic outer groove 704 through the liquid guide end tube 707. As the heat transfer oil inside the telescopic inner groove 702 and the telescopic outer groove 704 continues to increase, the protective outer film 703 will expand outward as a whole.

[0063] In the initial stage of expansion of the protective outer film 703, the protective inner film 701 and the upper limit magnetic strip 705 of the protective outer film 703 are mutually attracted and limited, so that the partial structure between the protective inner film 701 and the protective outer film 703 can be continuously attracted together. When the hydraulic pressure inside the telescopic inner groove 702 and the telescopic outer groove 704 reaches a predetermined threshold, the mutually attracted limit magnetic strips 705 are quickly separated under the combined action of the internal pressure of the telescopic outer groove 704 and the deformation elastic force of the protective outer film 703, and the protective outer film 703 and the protective inner film 704 are separated. During the separation process between the protective inner film 701 and the protective outer film 703, the protective outer layer 9 is quickly squeezed, so that the outer diameter of the protective outer layer 9 increases slightly and rapidly. At the same time, since the squeezing force of the three groups of protective inner films 701 and the protective outer film 703 on the protective outer layer 9 is different, the cable can also be driven to perform a high-frequency slight shaking in the process of separating the protective inner film 701 from the protective outer film 703, and the inertia generated during the shaking of the cable is used to accelerate the flow of the condensed liquid on the outer side of the cable, so as to achieve rapid cleaning of the corrosive solution outside the protective outer layer 9;

[0064] While the extrusion arc capsule 710 is alternately extruded, the heat inside the cable can also be guided and diffused. The heat transfer oil can be introduced into the arc extrusion inner box 801 through the arc liquid guide box 708. When the pressure inside the arc extrusion inner box 801 rises, the extrusion sleeve 803 is driven by the heat transfer oil to slide along the center of the guide arc plate 802. In the process of the extrusion sleeve 803 sliding, the elastic force of the elastic limit rope 804 is overcome to drive the isolation elastic cover 809 to be extruded into the internal heat absorption wide strip 805. As the extrusion sleeve 803 is gradually inserted into the internal heat absorption wide strip 805, the internal space of the internal heat absorption wide strip 805 is compressed.

[0065] While the internal space of the internal heat-absorbing wide strip 805 is reduced, the heat-conducting oil is introduced into the circulation narrow strip 807 through the liquid-conducting inclined tube 806, and the circulation narrow strip 807 is connected to the top of the internal heat-absorbing wide strip 805 through the guide arc tube 808. Through the flow of heat-conducting oil between the internal heat-absorbing wide strip 805 and the circulation narrow strip 807, the high-temperature heat-conducting oil of the internal heat-absorbing wide strip 805 located in the inner layer of the cable is introduced into the circulation narrow strip 807 located in the outer layer, so that the circulation narrow strip 807 expands slightly, and the heat of the inner layer of the cable is diffused outwardly. When the circulation narrow strip 807 expands, it contacts the inner arc surface of the protective inner film 701 more closely, so as to realize the heat exchange between the circulation narrow strip 807 and the heat-conducting oil inside the protective inner film 701, thereby optimizing the heat dissipation process of the cable.
