[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Embodiment 1

[0029] At present, with the development of modernization of China's industry, cables are used in various aspects of the national economy and people's life, and people have put forward higher requirements for the performance of cables. Single cooling through simple materials cannot meet people's demand for cables, and therefore cables must develop towards functionalization and diversification.

[0030] In order to solve the above technical problems, please refer to Figures 1 to 6As shown, the anti-corrosion, high-temperature-resistant and tear-resistant cable of one embodiment of the present application comprises a cable core body 1, a functional layer 2 and an outer protective layer 3 are sequentially arranged outside the cable core body 1, further comprises a supporting assembly 4 and a heat dissipation assembly 5, the supporting assembly 4 comprises an inner supporting piece 401 fixed on the outer wall of the functional layer 2, an outer supporting piece 402 is fixedly arranged on the inner wall of the outer protective layer 3, the heat dissipation assembly 5 comprises a cavity 501 between the inner supporting piece 401 and the outer supporting piece 402 and the functional layer 2 and the outer protective layer 3, a heat-absorbing material 502 is arranged in the cavity 501, a plurality of communication grooves 404 are arranged on each inner supporting piece 401 and outer supporting piece 402 at intervals, each communication groove 404 is in communication with the corresponding cavity 501, a plurality of accommodating grooves 405 are arranged on each inner supporting piece 401 and outer supporting piece 402 and face the corresponding cavity 501, a thermal expansion piece 406 is arranged in each accommodating groove 405, the heat-absorbing material 502 has a certain fluidity, when the temperature inside the cable core body 1 rises, the heat-absorbing material 502 absorbs a large amount of heat, the thermal energy makes the thermal expansion piece 406 expand and extrude the heat-absorbing material 502, so that the heat-absorbing material 502 is discharged into the cavity 501 connected through the communication groove 404, and the heat is conducted to the cavity 501 away from the cable core body 1.

[0031] In use, as the cable is used, heat is gradually generated inside, the generated heat makes the heat-absorbing material 502 absorb a large amount of heat, the large amount of heat is transferred to the thermal expansion piece 406 in the accommodating groove 405 corresponding to the outer supporting piece 402, so that the thermal expansion piece 406 expands and extrudes the heat-absorbing material 502, and the heat-absorbing material 502 close to the cable core body 1 is extruded by the thermal expansion piece 406 and discharged into the cavity 501 away from the cable core body 1 through the communication groove 404, so that the heat is conducted to the cavity 501 outside, and the heat-absorbing material 502 in the cavity 501 outside absorbs the heat.

[0032] Meanwhile, the heat-absorbing material 502 in the cavity 501 outside absorbs heat and conducts to the thermal expansion piece 406 on the inner supporting piece 401, the corresponding thermal expansion piece 406 of the inner supporting piece 401 expands and extrudes the heat-absorbing material 502 at this position, so that the heat-absorbing material 502 at this position is discharged into the cavity 501 close to the cable core body 1 through the communication groove 404, through continuous cooling and heating, the thermal expansion piece 406 continuously expands and shrinks, extruding the heat-absorbing material 502 to move in different cavities 501 through the communication groove 404, so that the heat-absorbing material 502 is exchanged, further reducing the temperature of the cable core body 1, and the heat-absorbing material 502 away from the cable core body 1 gradually conducts heat to the outside through the outer protective layer 3, achieving the effect of circulating heat dissipation.

[0033] When the cable is extruded, due to the provision of the inner support 401 and the outer support 402, when extruded from the outside, the outer support 402 extrudes the inner support 401, and the inner support 401 extrudes the adjacent outer support 402, which in turn provides the extruded inner support 401 with a support force, so that all the inner supports 401 and the outer supports 402 extrude and support each other, thereby achieving the effect of resisting pressure, and the heat-absorbing material 502 can provide a buffering effect, when extruded, a buffering force is provided to prevent excessive pressure from being transmitted to the cable core body 1.

[0034] By providing the cavity 501, the thermal expansion member 406 and the communication groove 404, the cavities 501 and the heat-absorbing material 502 near and away from the cable core body 1 can flow in different cavities 501 through the expansion and contraction of the thermal expansion member 406, thereby achieving the effect of gradual cooling, and the inner supports 401 and the outer supports 402 extruded and supported each other can achieve good pressure resistance effect. Embodiment 2

[0035] When the cable is used in engineering machinery applications, not only is the temperature in the field relatively high, but also due to the use of lubricating oil and other maintenance during use of the machinery, it is inevitable that the cable surface will be contaminated with oil and other contaminants, which will penetrate into the cable over a long period of time, resulting in a reduction in the service life of the cable.

[0036] On the basis of the above embodiment, in order to solve the above technical problems, please refer to Figures 1 to 6 As shown, the technical scheme adopted includes a functional layer 2 and an outer protective layer 3, the functional layer 2 includes an insulating layer 201, the outer wall of the insulating layer 201 is provided with a shielding layer 202, the outer wall of the shielding layer 202 is provided with a barrier layer 203, the outer protective layer 3 includes a corrosion-resistant layer 301 fixedly connected with the outer support 402, the outer wall of the corrosion-resistant layer 301 is provided with a protective layer 302, and the outer side of the protective layer 302 is provided with an armored layer 303.

[0037] In use, when the oil and other contaminants on the outside adhere to the armored layer 303 and the protective layer 302 for a long time, the oil and other contaminants will gradually corrode and penetrate into the protective layer 302 over a long enough period of time, thereby causing corrosion to the inside of the cable and further reducing the service life and damaging the cable, when the oil and other contaminants penetrate through the protective layer 302, the oil and other contaminants will be blocked by the corrosion-resistant layer 301, thereby avoiding continuous penetration of the oil and other contaminants, and the heat-absorbing material 502 is flowable and will solidify when it encounters hydrocarbons in the oil and other contaminants, so that the heat-absorbing material 502 can react and solidify with the oil and other contaminants, thereby producing a plugging effect to block the oil and other contaminants in a timely manner after the corrosion-resistant layer 301 is damaged.

[0038] Since the heat-absorbing material 502 has fluidity, the anti-permeation layer 203 is arranged to prevent the heat-absorbing material 502 from permeating outside the shielding layer 202, the corrosion-preventing layer 301 is arranged to prevent the heat-absorbing material 502 from permeating to the outside world, to prevent the heat-absorbing material 502 from flowing to the cable core body 1, and since the inner support 401 and the outer support 402 can be used to resist pressure, the cable inside can be prevented from being damaged and extruded to the insulation layer 201 and the anti-permeation layer 203, etc., thereby playing a better protection and plugging effect.

[0039] By arranging the anti-permeation layer 203 and the corrosion-preventing layer 301, oil stains and the heat-absorbing material 502 can be prevented from corroding the inside of the cable, thereby preventing oil stains and the like from corroding the cable and causing damage to the cable, and by arranging the anti-permeation layer 203 and the corrosion-preventing layer 301, the heat-absorbing material 502 can be prevented from interfering with the protective layer 302 and the shielding layer 202, etc., thereby playing a better corrosion-preventing effect. Embodiment 3

[0040] In the engineering machinery, due to the movement of the machinery and the movement and work of the machinery, the cable will be subjected to pulling force and tearing force, etc. The existing cable has a certain anti-pulling ability due to the material properties, etc., but when subjected to tearing force, it still has the problem that the cable surface is easily damaged.

[0041] On the basis of the above-mentioned embodiments one and two, in order to solve the above-mentioned technical problems, please refer to Figures 1 to 6 As shown in the figure, the technical scheme adopted includes an inner support 401, and a plurality of anti-tearing members 403 are arranged on the inner support 401 and the outer support 402, the inner support 401 and the outer support 402 are spirally distributed, each anti-tearing member 403 is spirally distributed and penetrates each inner support 401 and outer support 402, each anti-tearing member 403 is in sliding connection with the inner support 401 and the outer support 402, and the spiral direction of the anti-tearing member 403 is opposite to that of the inner support 401 and the outer support 402.

[0042] On the basis of the above-mentioned embodiments, when the cable is subjected to tearing force, since the inner support 401 and the outer support 402 are arranged, when subjected to tearing or extrusion, the outer support 402 will extrude the adjacent inner support 401, and the adjacent inner support 401 will apply a counterforce to the outer support 402, thereby forming mutual extrusion and support of the adjacent inner support 401 and the outer support 402, and forming a first anti-tearing and extrusion effect.

[0043] When the tearing force is large, the tearing force has a tendency to pull the outer support member 402 out of the adjacent inner support member 401, but because of the cavities 501, heat absorbing material 502 and the communication groove 404, the heat absorbing material 502 and the cavities 501 provide a reverse pulling force when the tearing force is applied, so as to prevent the outer protective layer 302 from being pulled too severely and damaged, thereby forming a second anti-tearing effect.

[0044] When the tearing force is larger, the tearing force can pull the outer support member 402 out of contact with the adjacent inner support member 401, and at this time, because the anti-tearing member 403 provides a pulling force to the outer support member 402 being pulled, the outer support member 402 and the protective layer 302 are prevented from being continuously pulled by the tearing force when the tearing force is applied, thereby achieving a third anti-tearing effect.

[0045] When the cable is subjected to a torsional force, because the inner support member 401 and the outer support member 402 are spirally distributed, when subjected to a torsional force, they can be pressed and supported with each other to prevent the torsional force from directly twisting the cable core body 1, thereby achieving an anti-torsion effect. When the torsional force is large, because of the heat absorbing material 502 and the like, a certain adhesion effect can be produced, thereby producing a certain anti-torsion effect when torsion occurs. When the torsional force is large, because of the anti-tearing member 403, when the inner support member 401 and the outer support member 402 are continuously twisted, the anti-tearing member 403 will pull the inner support member 401 and the outer support member 402, thereby providing a force for the inner support member 401 and the outer support member 402 to move closer to each other, so as to resist the torsional force, thereby achieving a good anti-torsion effect and preventing the torsional force from damaging the cable core body 1.

[0046] When the cable is subjected to a tensile force, because the inner support member 401 and the outer support member 402 are embedded in each other, the functional layer 2 and the outer protective layer 3 can slide relative to each other, and when subjected to a tensile force, the inner support member 401 and the outer support member 402 can slide relative to each other, thereby preventing the external tensile force from directly acting on the cable core body 1, thereby achieving a good anti-tensile effect. When the tensile force is large, the anti-tearing member 403 will act on the inner support member 401 and the outer support member 402, so that the inner support member 401 and the outer support member 402 move closer to each other, thereby preventing the inner support member 401 and the outer support member 402 from sliding relative to each other, thereby further achieving an anti-tensile effect.

[0047] The anti-tearing member 403, the inner support member 401 and the outer support member 402 are arranged to interact with each other when the cable is subjected to a tearing force, so that when the cable is subjected to a tearing force and a torsional force of different degrees, a counteracting force can always be produced to resist the external tearing force and the torsional force, thereby forming multiple levels of protection for the cable.

[0048] The above description is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent substitutions or changes according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
