DETAILED DESCRIPTION

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] Embodiment 1:

[0027] Reference Figure 1-2 A novel water-blocking and moisture-proof power cable comprises an insulating core sleeve 1, a cable conductor 13 is arranged inside the insulating core sleeve 1, and a conductor shielding layer 14 is arranged between the outer side of the cable conductor 13 and the insulating core sleeve 1, the outer side of the insulating core sleeve 1 is coated with an insulator shielding layer 2, and the outer side of the insulator shielding layer 2 is coated with an inner water-blocking tape layer 3, the outer side of the inner water-blocking tape layer 3 is coated with a flexible buffer layer 4, and the outer side of the flexible buffer layer 4 is coated with an outer water-blocking tape layer 8, and the outer side of the outer water-blocking tape layer 8 is coated with a metal braided shielding layer Layer 9, and the outer side of the metal braided shielding layer 9 is covered with an asphalt protective layer 10, the outer side of the asphalt protective layer 10 is covered with a plastic film tape 11, and the outer side of the plastic film tape 11 is covered with a wear-resistant sheath 12, and the outer surface of the wear-resistant sheath 12 is provided with a plurality of spirally distributed protective ridges 7, and a protective armor mechanism 5 and a dividing strip 6 are arranged between the metal braided shielding layer 9 and the insulating core sleeve 1, and the protective armor mechanism 5 and the dividing strip 6 both penetrate the insulator shielding layer 2, the inner water-blocking tape layer 3, the flexible buffer layer 4 and the outer water-blocking tape layer 8.

[0028] In the present invention, an inner water-blocking tape layer 3 and an outer water-blocking tape layer 8 are provided, which are double-layer water-blocking, and an asphalt protective layer 10 is provided on the lower side of the plastic film tape 11. The asphalt protective layer 10 is glued and squeezed into the plastic film tape 11, and the asphalt fills the woven mesh gaps of the metal braided shielding layer 9. When the cable is in use, heat is generated inside the cable, which is transferred to the metal braided shielding layer 9 through the protective armor mechanism 5 and the partition strip 6 for heat dissipation, thereby increasing the fluidity of the asphalt layer. When the surface wear-resistant sheath 12 of the cable is damaged and cracks appear, the glued asphalt quickly fills the gaps and squeezes out the infiltrated water. Insect and rodent repellents can be added to the asphalt raw materials during production. When cracks occur, the odors of the agents and the asphalt itself pass through the cracks. The asphalt can effectively repel insects and rats, and the asphalt can quickly solidify when encountering the wet and cold environment in the tunnel, which can further prevent water from penetrating into the cable, thereby enhancing the water-blocking and moisture-proof effects of the cable. At the same time, the multi-layer structure of the cable is reinforced by the protective armor mechanism 5 and the dividing strips 6 to enhance the stability of the internal structure of the cable, avoid bending and breaking of the cable during laying and application, and improve the stability of the cable. Secondly, the setting of the protective ridges 7, when the cable is dragged or vibrated, and the surface comes into contact with foreign objects such as the ground, the protective ridges 7 are the first to be worn, thereby improving the protection effect of the surface layer of the cable. When used in the tunnel, the protective ridges 7 constitute drainage protrusions to prevent water droplets from adhering to the cable surface.

[0029] As a further solution in the present invention, the protective armor mechanism 5 includes a heat absorbing member 511 embedded in the insulating core sleeve 1, and a heat sink 513 embedded in the inner layer of the metal braided shielding layer 9, and an arc-shaped connecting member 512 is arranged between the heat absorbing member 511 and the heat sink 513. The heat absorbing member 511 is distributed in an arc shape around the cable conductor 13. When the cable transmits electricity, the heat generated by the cable conductor 13 is transferred to the metal braided shielding layer 9 through the heat absorbing member 511, the connecting member 512 and the heat sink 513, and then transferred to the surface of the cable for dissipation, thereby improving the heat dissipation efficiency of the cable core. Secondly, the heat sink 513 forms armor in the middle of the cable, and cooperates with the metal braided shielding layer 9 to enhance the cable's anti-puncture and wear strength, thereby improving the stability of the cable use.

[0030] As a further solution in the present invention, the protective armor mechanism 5 also includes a plurality of guide pillars 514 arranged on the outside of the heat sink 513, and a ring-shaped fixed ring sheet 515 is arranged on the outside of the guide pillars 514. The guide pillars 514 penetrate the pores of the metal braided shielding layer 9, and the fixed ring sheet 515 is wrapped inside the asphalt protective layer 10. With the help of the guide pillars 514 and the pores of the metal braided shielding layer 9, the glued asphalt is firmly adsorbed and fixed, thereby enhancing the stability of the asphalt protective layer 10 and enhancing the heat transfer to the center of the asphalt. When broken pores appear on the cable surface, the asphalt seeps out slowly, thereby enhancing the adhesion effect of the asphalt. At the same time, when the cable is used, the outermost elastic armor is formed between the plurality of fixed ring sheets 515 to avoid direct contact with the metal braided shielding layer 9 when the surface is worn, thereby enhancing wear resistance and shielding properties.

[0031] As a further solution in the present invention, the dividing strip 6 is clamped between the heat sink 513, and the bottom end of the dividing strip 6 and the insulating core sleeve 1 are an integrally formed structure. The middle layer structure of the cable is divided by the dividing strip 6. At the same time, the inner and outer layer structures of the cable are connected by the dividing strip 6, and the protective armor mechanism 5 is firmly positioned between the dividing strips 6 to avoid structural separation when the cable is twisted or bent, thereby enhancing the mechanical strength of the cable and maintaining the stability of the internal structure of the cable.

[0034] The protective armor mechanism 5 includes an elastic diaphragm 521 with a C-shaped cross-section embedded in the insulating core sleeve 1, and a support member 523 embedded in the inner layer of the metal braided shielding layer 9. A connecting support plate 522 is arranged between the elastic diaphragm 521 and the support member 523. The elastic diaphragm 521, the connecting support plate 522 and the support member 523 are distributed in a spiral shape. A spiral overhead structure is formed in the cable by the elastic diaphragm 521, the connecting support plate 522 and the support member 523 to reduce the dead weight of the cable. At the same time, an external armor is formed by the external arc-shaped support member 523 to enhance the anti-puncture effect of the cable and transfer the heat in the center of the cable to the outside. Secondly, its spiral distribution structure effectively improves the internal support effect and anti-twisting effect of the cable to avoid compression damage to the cable.

[0035] The protective armor mechanism 5 also includes a secondary support member 524 arranged in the middle of the flexible buffer layer 4, and the secondary support member 524 is connected between two connecting support plates 522. A plurality of arc-shaped reinforcing ribs 525 are arranged between the two connecting support plates 522. Through the setting of the secondary support member 524, the connection strength of the flexible buffer layer 4 in the middle of the cable is enhanced to resist impact and compression. Secondly, the thermal conductivity efficiency is enhanced. At the same time, the setting of the reinforcing ribs 525 reinforces the connecting support plates 522, enhances the anti-deformation effect, and effectively improves the armor protection effect of the cable.

[0036] One side surface of the dividing strip 6 is connected to the support member 523 and the auxiliary support member 524, and the dividing strip 6 is distributed in a spiral shape. The dividing strip 6 enhances the connection strength between the layers of the structure in the middle of the cable, and the dividing strip 6 separates the protective armor mechanism 5 into independent areas, thereby reducing mutual interference during wear and enhancing the moisture-proof effect of the cable.

[0039] The protective armor mechanism 5 includes a cavity 531 distributed inside the insulating core sleeve 1, and a plurality of capillaries 532 penetrating the insulating shielding layer 2, the inner water-blocking tape layer 3, and the flexible buffer layer 4 are distributed on the outside of the cavity 531. The end of the capillary 532 is provided with a plug 533 embedded in the inner layer of the outer water-blocking tape layer 8. A gel substance is injected into the cavity 531. When the outer water-blocking layer 8 is damaged, the plug 533 is removed together, and heat and pressure are generated when the cable is used. The gel substance inside the cavity 531 is squeezed out from the capillary 532, and the gel quickly diffuses to the broken part of the outer water-blocking layer 8 and solidifies to form a sealed armor, which quickly repairs the damaged part on the cable surface and improves the water-blocking and moisture-proof effect of the cable.

[0040] A dispersion capsule 534 is arranged on the outside of a middle section of the flexible buffer layer 4, and dense capillaries 536 are arranged on the outer surface of the dispersion capsule 534. A membrane tube 535 connected to the capillary 532 and the plug 533 is arranged inside the dispersion capsule 534. After the plug 533 is removed, part of the gel substance overflows from the top of the membrane tube 535 to fill the damaged part, and part of the gel substance enters the dispersion capsule 534 and penetrates into the flexible buffer layer 4 through the capillaries 536, solidifying the flexible buffer layer 4 into a solid armor, preventing the damaged part from extending inward again, and blocking the moisture on the outside, further enhancing the water-proof and moisture-proof effect.

The asphalt protective layer 10 is glued and squeezed into the plastic film tape 11, and the asphalt fills the woven mesh gaps of the metal braided shielding layer 9. When the cable is in use, heat is generated inside the cable, which is transferred to the metal braided shielding layer 9 through the protective armor mechanism 5 and the separator 6 to dissipate heat, thereby increasing the fluidity of the asphalt layer. When the surface wear-resistant sheath 12 of the cable is damaged and cracks appear, the glued asphalt quickly fills the gaps and squeezes out the infiltrated water. In addition, insect repellent and rat repellent can be added to the asphalt raw materials during production. When cracks occur, the odor of the agent and the asphalt itself is emitted through the cracks, which effectively repels insects and rats, and the asphalt solidifies quickly when encountering the damp and cold environment in the tunnel, further preventing water from penetrating into the cable, thereby enhancing the cable's water-blocking and moisture-proof effects. At the same time, the multi-layer structure of the cable is reinforced by the protective armor mechanism 5 and the dividing strips 6 to enhance the stability of the cable's internal structure, avoid bending and breaking of the cable during laying and application, and improve the cable's use stability. Secondly, the setting of the protective ridges 7, when the cable is dragged or vibrated, and when the surface comes into contact with foreign objects such as the ground, the protective ridges 7 are the first to be worn.
