Description

Technical Field

[0001] The present invention relates to the technical field of cables, and in particular to an integrated composite multifunctional cable. Background Art

[0002] In power transmission, communications, smart grids, and specialized industrial sectors, traditional cables typically perform only a single function (e.g., power transmission or communications). Modern applications, however, place higher demands on cables, including multifunctional integration, efficient heat dissipation, lightweight design, interference resistance, and long life. Integrated composite multifunctional cables are high-performance cables that integrate power transmission, signal communication, active heat dissipation, mechanical protection, and intelligent monitoring into a single cable body through the fusion of multiple materials and collaborative multi-structure design.

[0003] The existing integrated composite multifunctional cable has severe internal heating due to large current. Traditional air cooling or natural heat dissipation methods are inefficient, which can easily lead to aging of the insulation layer or even short circuits, and uneven heat conduction. Liquid-cooled cables have complex structures and are difficult to maintain. The cooling medium may leak, posing a safety hazard. They are easily damaged in extreme environments such as high temperature, corrosion, and vibration. They lack an integrated protective design and have insufficient tensile and compressive resistance, making them difficult to adapt to scenarios such as deep sea, mines, or mobile equipment.

[0004] An integrated composite multifunctional cable is urgently needed to solve this problem. Summary of the Invention

Furthermore, the accompanying drawings are intended only to provide a more detailed description of the embodiments and are not intended to limit the present invention.

[0038] like Figures 1 to 8 As shown, an embodiment of the present invention provides an integrated composite multifunctional cable, comprising: an integrated composite cable body 1, wherein the integrated composite cable body 1 comprises a deformation limiting unit 552, an air return unit 553, a cooling and ventilation unit 554, and a buffer protection unit 555;

[0040] The integrated unit 551 includes a cable connection buckle 2, an elastic auxiliary sheet 9, and a reinforced inner layer 15;

[0041] The deformation limiting unit 552 includes an arc-shaped rubber frame 8 and a protective ring cylinder 20;

[0042] The return air unit 553 includes an inner air casing 4, an insulating protective layer 7, and a wire core 11;

[0043] The cooling and ventilation unit 554 includes a cooling core 10, a mesh column 12, a porous pipe 13, and a flow diversion sleeve 14;

[0044] The buffer protection unit 555 includes a snap-fitting expansion piece 3, a limiting block 17, a side guard bar 18, and a back bar 19;

[0045] The cable connection buckle 2 is fixedly connected to one side of the integrated composite cable body 1, the reinforced inner layer 15 is arranged on the inner wall of the integrated composite cable body 1, and multiple groups of elastic auxiliary sheets 9 are fixedly connected to the inner surface of the reinforced inner layer 15, and each group of elastic auxiliary sheets 9 is two.

[0046] In one possible embodiment, a plurality of arc-shaped plastic frames 8 are fixedly connected to the outer surface of the reinforced inner layer 15 at equal intervals in an annular manner, and the arc-shaped plastic frame 8 is connected to the elastic auxiliary sheet 9;

[0047] Every two elastic auxiliary pieces 9 correspond to one arc-shaped rubber frame 8 .

[0048] It should be noted that the cooling gas can be fed into the cooling core 10 from one end. The cooling gas begins to circulate in the cooling core 10, which is beneficial to the overall cooling of the interior of the cable and will not produce any negative effects.

[0049] In one possible embodiment, the inner gas casing 4 is inserted into the inner side of the integrated composite cable body 1, the insulating protective layer 7 is annularly fixed to the outer surface of the inner gas casing 4, and the plurality of wire cores 11 are inserted into the middle of the insulating protective layer 7;

[0050] It should be noted that whenever the cooling gas passes through the through opening, it disperses and flows into each porous tube 13. A part of the gas entering the porous tube 13 is dispersed and circulated between the protective ring tube 20 and each insulating protective layer 7, and the other part flows between the protective ring tube 20 and the reinforced inner layer 15. The present invention continuously cools the heat inside the cable through the cooling gas. After a period of cooling, the circulating gas equipment can be opened from the cable connection station to inhale the gas in the inner gas casing 4. This can be achieved. The present invention can avoid the influence of cable heating, and can evenly conduct heat inside and circulate cooling.

[0051] In a possible embodiment, a plurality of the mesh columns 12 are equidistantly interspersed on the outer surface of the inner gas casing 4, the mesh columns 12 all pass through the protective ring tube 20 and enter the inner side of the arc-shaped rubber frame 8, the cooling inner core 10 is fixedly connected to the inner side of the inner gas casing 4, and a plurality of the porous tubes 13 are annularly equidistantly interspersed on the outer surface of the cooling inner core 10, and a plurality of the porous tubes 13 are interspersed with the reinforced inner layer 15, and the pressure is transmitted to the reinforced inner layer 15 through the pressure surface of the integrated composite cable body 1, and the insulating protective layer 7 described in the upper part is connected to the protective ring tube 20 by the generated suction. The gas in the parts and the gas between the protective ring tube 20 and the reinforced inner layer 15 are sucked in, and after being discharged and cooled, they are continuously circulated and transported to the cooling inner core 10 to complete the process. Then, the reinforced inner layer 15 drives the elastic auxiliary sheet 9 to resist the arc-shaped plastic frame 8. After the resistance, the arc-shaped plastic frame 8 and the elastic auxiliary sheet 9 are deformed, thereby reducing the squeeze damage to the internal wire core 11. Under the restriction of the mesh column 12 and the perforated tube 13, the overall deformation amplitude of the integrated composite cable body 1 is guaranteed, which is beneficial for the cable to reduce the damage to the cable caused by the use factors in extreme environments and ensure the overall safety and service life of the cable.

The limiting blocks 17 correspond to the side bars 18. When the integrated composite cable body 1 is deformed after being compressed, the cable connection ring buckle 2 will also be involved in the movement, thereby driving the snap-fit ​​expansion piece 3 to move, thereby driving the limiting blocks 17 to interact with the side bars 18 and the back bar 19, which is beneficial to protecting the cable after being subjected to external force, slowing down the hard bending of the cable, and ensuring its service life.

[0054] The beneficial effects brought about by the technical solution provided by the embodiment of the present invention include at least:

[0055] In the present invention, cooling gas is dispersed and flows into each porous tube. Part of the gas entering the porous tube is dispersed and circulated between the protective ring tube and each insulating protective layer, and the other part flows between the protective ring tube and the reinforced inner layer. The cooling gas continuously cools the heat inside the cable. After a period of cooling, the circulating gas equipment can be opened from the cable connection station to absorb the gas in the inner gas casing, the gas between the insulating protective layer and the protective ring tube described in the above part, and the gas between the protective ring tube and the reinforced inner layer. After being discharged and cooled, it continues to circulate and transported to the cooling core to complete the process.
