Description

Technical Field

[0001] The present invention relates to the technical field of cables, and in particular to a corrosion-resistant, high-temperature-resistant and tear-resistant cable. Background Art

[0002] At present, with the development of my country's modern industry, cables are used in all aspects of the national economy and people's lives. People have put forward higher requirements on the performance of high-temperature cables and high-temperature resistant cable materials. Cables and cable materials with single high-temperature resistant performance can no longer meet people's demand for cables. Therefore, cables must develop in the direction of functionalization and diversification.

[0003] When cables are used in engineering machinery, not only is the temperature high in the field, but the machinery also requires regular lubrication and other maintenance, which inevitably causes the cable surface to be contaminated with oil. The long-term accumulation of oil will cause the oil to penetrate into the cable, resulting in a reduced service life of the cable.

[0004] In construction machinery, the movement, relocation and operation of the machinery will cause the cables to be subjected to pulling and tearing forces. Although the existing cables have a certain degree of tensile strength due to reasons such as material properties, when the cables are subjected to tearing and torsional forces of different strengths, they cannot form multi-level protection for the inside of the cables, and there is still a situation where the cables are easily damaged. Summary of the Invention

[0005] The purpose of the present invention is to provide a corrosion-resistant, high-temperature-resistant and tear-resistant cable to solve the technical problem proposed in the above background technology that the cable cannot form multi-level protection inside the cable when subjected to tearing and torsional forces of different strengths.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a corrosion-resistant, high-temperature-resistant and tear-resistant cable, comprising a cable core body, a functional layer and an outer sheath being sequentially arranged on the outer side of the cable core body, and further comprising: A support assembly, the support assembly comprising an inner support member fixed to the outer wall of the functional layer, an outer support member fixed to the inner wall of the outer protective layer, and a plurality of tear-proof members being provided on both the inner support member and the outer support member; The heat dissipation component includes a cavity located between the inner support member, the outer support member, the functional layer and the outer protective layer, and a heat-absorbing material is provided in the cavity.

[0007] Preferably, each of the inner support member and the outer support member is provided with a plurality of communication grooves spaced apart from each other, and each of the communication grooves is communicated with a corresponding cavity.

[0008] Preferably, each of the inner support member and the outer support member is provided with a plurality of receiving grooves facing the corresponding cavity, and a thermal expansion member is provided in each of the receiving grooves.

[0009] Preferably, the heat-absorbing material has a certain fluidity.

[0010] Preferably, when the temperature inside the cable core body rises, the heat absorbing material absorbs a large amount of heat. The heat energy causes the heat expansion member to expand and squeeze the heat absorbing material, so that the heat absorbing material is discharged into the connected cavity through the connecting groove, and the heat is conducted to the cavity away from the cable core body.

[0011] Preferably, the inner support members and the outer support members are both spirally distributed.

[0012] Preferably, each of the tear-proof members is spirally distributed and passes through each of the inner support member and the outer support member, and each of the tear-proof members is slidably connected to the inner support member and the outer support member.

[0013] Preferably, the tear-proof member has a spiral direction opposite to that of the inner support member and the outer support member.

[0014] Preferably, the functional layer includes an insulating layer, an outer wall of the insulating layer is provided with a shielding layer, and an outer wall of the shielding layer is provided with an anti-seepage layer.

[0015] Preferably, the outer protective layer includes an anti-corrosion layer fixedly connected to the outer support member, the outer wall of the anti-corrosion layer is provided with a protective layer, and the outer side of the protective layer is provided with an armor layer.

[0016] The beneficial effects of the present invention are: 1. By setting cavities, thermal expansion parts and connecting grooves, heat-absorbing materials can flow in different cavities, thereby achieving a gradual cooling effect. The inner and outer supports that squeeze and support each other can achieve a good pressure resistance effect; the anti-seepage layer and anti-corrosion layer can prevent oil and heat-absorbing materials from corroding the inside of the cable, thereby preventing oil and other corrosion from causing damage to the cable; when the cable is subjected to tearing force and torsional force, the inner and outer supports, anti-tear parts and heat-absorbing materials interact with each other, so that when the cable is subjected to tearing force and torsional force of different strengths, it can always generate a reaction force to resist the external tearing force and torsional force, thereby forming multi-level protection for the inside of the cable.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. Example 1

[0025] At present, with the development of my country's modern industry, cables are used in all aspects of the national economy and people's lives. People have put forward higher requirements on the performance of cables. Simple material cooling alone can no longer meet people's needs for cables. Therefore, cables must develop in the direction of functionalization and diversification.

[0026] To solve the above technical problems, please refer to Figures 1 to 6As shown, a corrosion-resistant, high-temperature-resistant and tear-resistant cable according to an embodiment of the present invention includes a cable core body 1, a functional layer 2 and an outer sheath 3 are sequentially arranged on the outside of the cable core body 1, a support assembly 4 and a heat dissipation assembly 5, the support assembly 4 includes an inner support member 401 fixed to the outer wall of the functional layer 2, an outer support member 402 is fixed to the inner wall of the outer sheath 3, the heat dissipation assembly 5 includes a cavity 501 located between the inner support member 401 and the outer support member 402 and the functional layer 2 and the outer sheath 3, a heat-absorbing material 502 is provided in the cavity 501, and a plurality of connecting grooves 404 are spaced apart on each inner support member 401 and the outer support member 402. Each communication groove 404 is connected to the corresponding cavity 501. Each inner support member 401 and outer support member 402 is provided with a plurality of receiving grooves 405 facing the corresponding cavity 501. A heat expansion member 406 is provided in each receiving 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 heat energy causes the heat expansion member 406 to expand and squeeze the heat absorbing material 502, so that the heat absorbing material 502 is discharged into the connected cavity 501 through the communication groove 404, and the heat is conducted to the cavity 501 away from the cable core body 1.

[0027] During use, as the cable is used, heat will gradually be generated inside. The generated heat causes the heat-absorbing material 502 to absorb a large amount of heat, and a large amount of heat is transferred to the heat expansion member 406 in the corresponding accommodating groove 405 of the outer support member 402, causing the heat expansion member 406 to expand and squeeze the heat-absorbing material 502, so that the heat-absorbing material 502 close to the cable core body 1 is squeezed by the heat expansion member 406 through the connecting groove 404 and discharged into the cavity 501 away from the cable core body 1, thereby conducting the heat to the external cavity 501, so that the heat-absorbing material 502 in the external cavity 501 absorbs heat.

[0028] At the same time, the heat-absorbing material 502 in the external cavity 501 absorbs heat and conducts it to the thermal expansion member 406 on the inner support member 401. The thermal expansion member 406 corresponding to the inner support member 401 expands and squeezes the heat-absorbing material 502 there, so that the heat-absorbing material 502 there is discharged into the cavity 501 close to the cable core body 1 through the connecting groove 404. Through continuous cooling and heating, the thermal expansion member 406 continuously expands and contracts, squeezing the heat-absorbing material 502 to move in different cavities 501 through the connecting groove 404, thereby exchanging the heat-absorbing material 502, further reducing the temperature of the cable core body 1. At the same time, the heat-absorbing material 502 away from the cable core body 1 gradually conducts heat to the outside through the outer sheath 3, thereby achieving the effect of circulating heat dissipation.

[0029] When the cable is squeezed, due to the provision of inner support members 401 and outer support members 402, when squeezed from the outside, the outer support members 402 squeeze the inner support members 401, and the inner support members 401 squeeze the adjacent outer support members 402, and the adjacent outer support members 402 provide supporting force to the inner support members 401 that squeeze them, so that all the inner support members 401 and the outer support members 402 squeeze and support each other, thereby achieving a pressure-resistant effect. At the same time, the heat-absorbing material 502 can provide a buffering effect, and when squeezed, it provides a buffering force to prevent excessive pressure from being transmitted to the cable core body 1.

[0030] By providing the cavity 501, the thermal expansion member 406 and the connecting groove 404, the cavity 501 and the heat-absorbing material 502 close to and far away from the cable core body 1 can expand and contract the thermal expansion member 406, so that the heat-absorbing material 502 can flow in different cavities 501, thereby achieving a gradual cooling effect. The inner support member 401 and the outer support member 402 that squeeze and support each other can achieve a good pressure resistance effect. Example 2

[0031] When cables are used in engineering machinery, not only is the temperature in the site high, but the machinery also requires regular lubrication and other maintenance, which inevitably causes the cable surface to be contaminated with oil. Over time, the oil will penetrate into the interior of the cable, reducing the cable's service life.

[0032] On the basis of the above embodiments, in order to solve the above technical problems, please refer to Figures 1 to 6 As shown, the adopted technical solution 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 an anti-seepage layer 203, the outer protective layer 3 includes an anti-corrosion layer 301 fixedly connected to the outer support member 402, the outer wall of the anti-corrosion layer 301 is provided with a protective layer 302, and the outer side of the protective layer 302 is provided with an armor layer 303.

[0033] During use, when external oil and dirt adhere to the armor layer 303 and the protective layer 302 for a long time, the oil and dirt will gradually corrode and penetrate into the protective layer 302 after a long enough period of accumulation, thereby causing corrosion to the interior of the cable, and further resulting in a reduced life of the cable and damage. When the oil and dirt penetrate through the protective layer 302, the oil and dirt will be blocked by the anti-corrosion layer 301, thereby avoiding the continuous infiltration of the oil and dirt. While the heat-absorbing material 502 is fluid, it will solidify when encountering hydrocarbons in the oil and dirt. When the anti-corrosion layer 301 is damaged, the heat-absorbing material 502 can react with the oil and solidify, thereby producing a blocking effect, preventing the oil and dirt from being blocked in time after the anti-corrosion layer 301 is damaged.

[0034] Since the heat-absorbing material 502 is fluid, an anti-seepage layer 203 is provided to prevent the heat-absorbing material 502 from penetrating to the outside of the shielding layer 202. The anti-corrosion layer 301 is used to prevent the heat-absorbing material 502 from penetrating to the outside and prevent the heat-absorbing material 502 from flowing to the cable core body 1. Moreover, since the inner support 401 and the outer support 402 can be used to resist pressure, they can prevent the inside of the cable from being damaged and squeezed to the insulating layer 201 and the anti-seepage layer 203, thereby playing a better protection and sealing role.

[0035] The provision of the anti-seepage layer 203 and the anti-corrosion layer 301 can prevent oil stains and the heat-absorbing material 502 from corroding the interior of the cable, thereby preventing oil stains and the like from corroding the cable and causing damage to the cable. Furthermore, the provision of the anti-seepage layer 203 and the anti-corrosion layer 301 can prevent the heat-absorbing material 502 from interfering with the protective layer 302 and the shielding layer 202, thereby achieving a better anti-corrosion effect. Example 3

[0036] In construction machinery, the movement, relocation and operation of the machinery will cause the cables to be subjected to pulling and tearing forces. Although existing cables have a certain degree of tensile resistance due to material properties, when subjected to tearing forces, there is still a situation where large cracks are easily formed on the cable surface.

[0037] On the basis of the above-mentioned embodiment 1 and embodiment 2, in order to solve the above-mentioned technical problems, please refer to Figures 1 to 6 As shown, the adopted technical solution includes an inner support member 401, and a plurality of anti-tear members 403 are commonly provided on the inner support member 401 and the outer support member 402. The inner support member 401 and the outer support member 402 are both spirally distributed, and each anti-tear member 403 is spirally distributed and passes through each inner support member 401 and the outer support member 402. Each anti-tear member 403 is slidingly connected to the inner support member 401 and the outer support member 402, and the spiral direction of the anti-tear member 403 is opposite to that of the inner support member 401 and the outer support member 402.

[0038] Based on the above embodiment, when the cable is subjected to a tearing force, due to the provision of an inner support member 401 and an outer support member 402, when it is torn or squeezed, the outer support member 402 will squeeze the adjacent inner support member 401, and at the same time, the adjacent inner support member 401 will apply a reaction force to the outer support member 402, thereby forming adjacent inner support members 401 and outer support members 402 squeezing and supporting each other, forming a first anti-tearing and squeezing effect.

[0039] When the tearing force is large and tends to pull the outer support member 402 out from between the adjacent inner support members 401, due to the provision of the cavity 501, the heat-absorbing material 502 and the connecting groove 404, in order to maintain the pressure inside the cable stable when subjected to the tearing force, the heat-absorbing material 502 and the cavity 501 provide a reverse pulling force, thereby preventing the outer protective layer 302 from being pulled too severely and causing damage, forming a second anti-tearing effect.

[0040] When the tearing force is greater, the tearing force may pull out the outer support member 402 so that it does not contact the adjacent inner support member 401. At this time, the anti-tear member 403 applies pulling force to the torn outer support member 402, so that when the outer support member 402 and the protective layer 302 are subjected to the tearing force, the continued tearing of the tearing force is blocked, thereby achieving the third anti-tear effect.

[0041] When the cable is subjected to torsional force, since the inner support member 401 and the outer support member 402 are spirally distributed, when subjected to torsion, they can use the mutual squeezing and support to prevent the torsional force from causing direct torsion on the cable core body 1, thereby playing an anti-twisting effect. When the torsional force is large, due to the provision of heat-absorbing materials 502, etc., a certain adhesion effect can be produced, thereby producing a certain anti-twisting effect when torsion occurs. When the torsional force is large, due to the provision of anti-tear parts 403, when the inner support member 401 and the outer support member 402 continue to twist, the anti-tear parts 403 will be forced to pull the inner support member 401 and the outer support member 402, giving the inner support member 401 and the outer support member 402 a force to move closer to each other, thereby resisting the torsional force, thereby playing a good anti-twisting effect and preventing the torsional force from causing damage to the cable core body 1.

[0042] When the cable is subjected to tensile force, the inner support member 401 and the outer support member 402 are interlocked with each other, so that relative sliding can occur between the functional layer 2 and the outer sheath 3. When subjected to 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-tear member 403 is forced to 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 are close to each other, preventing the relative sliding between the inner support member 401 and the outer support member 402, and further achieving an anti-tensile effect.

[0043] By setting up the anti-tear part 403, the inner support part 401 and the outer support part 402, when the cable is subjected to a tearing force, the inner support part 401, the outer support part 402, the anti-tear part 403 and the heat-absorbing material 502 interact with each other, so that when the cable is subjected to tearing forces and torsional forces of different strengths, a reaction force can always be generated to resist the external tearing force and torsional force, thereby forming multi-level protection for the inside of the cable.

[0044] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
