Technical Field
[0001] This invention relates to the field of radial water-blocking cable technology, specifically a rodent-proof and ant-proof radial water-blocking cable. Background Technology
[0002] Rodent-proof and termite-proof radial water-blocking cable is a special cable that integrates multiple protective functions. It is designed for complex environments (such as underground direct burial, humid areas, and areas with high rodent and termite incidence). It can resist the gnawing of rodents, termite infestation, and water penetration at the same time, ensuring the long-term stable operation of the cable under harsh conditions. For this purpose, a Chinese patent discloses a rodent-proof and termite-proof double water-blocking power cable, application number CN201320625824.9. This patented model adds the function of preventing rats and termites from biting through the sheath by making the cable radially and longitudinally waterproof, ultimately extending the normal use of the buried cable.

[0025] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use.
[0026] 1. A three-dimensional isolation and protection mechanism is set up. Through the cooperation between the various components inside the three-dimensional isolation and protection mechanism, the protection process of radial water-blocking cable is optimized. The components are installed on the outside of the cable by protective rubber cards and rubber isolation arc boxes. By strengthening the outer layer structure of the radial water-blocking cable, the difficulty of rats and termites gnawing on the cable is increased, and the degree and rate of damage caused by rats and termites are reduced. The cable's anti-penetration ability is strengthened by protective ceramic arc plates, which effectively improves the service life of the cable. At the same time, the splicing structure design of the cable's exterior simplifies the inspection and maintenance process during the use of the cable. It allows maintenance personnel to quickly cut and replace damaged parts during the maintenance process, thereby effectively reducing the use and maintenance costs of the cable and further improving the convenience of using radial water-blocking cable.
[0027] Meanwhile, the hollow structure of the rubber-insulated arc-shaped box isolates the internal and external spaces of the cable, reducing the rate at which heat is directly transferred from the cable to the outside and the rate at which external moisture directly penetrates the cable. The semi-open structure of the telescopic venting tube and the one-way exhaust box directs heat and moisture from the cable away from the cable body, thus maintaining the cable's temperature and humidity. This ensures that the internal temperature and humidity of the cable remain within a suitable range during use. It also effectively prevents heat from directly dissipating into adjacent spaces, thus preventing localized temperature increases around the cable. This also prevents rodents and ants from gathering around the cable due to their attraction to heat, reducing the probability of rodent and ant damage and effectively improving the cable's overall rodent and ant resistance, further extending its service life.
[0028] 2. An internal staggered snap-fit support mechanism is installed. Through the cooperation between the various components inside the internal staggered snap-fit support mechanism, the overall protection process during the use of radial water-blocking cable is optimized. The snap-fit structure design of the internal components of the cable maintains the position of the internal components, effectively preventing the internal components from affecting the normal use of the cable due to random displacement during use. At the same time, the cooperation between the components outside the internal splicing rubber sleeve effectively strengthens the connection strength between the inner and outer layers of the cable, thereby effectively improving the stability of the overall cable structure and ensuring that the cable can maintain structural stability during continuous operation, further improving the performance of radial water-blocking cable.
[0029] Meanwhile, the elastic clamping structure between the elastic retainer and the arc-shaped conduit allows the cable to temporarily maintain its shape after compression when subjected to low-intensity reciprocating compression. This is achieved through the clamping of the central arc groove and the arc-shaped clamping piece, effectively preventing fatigue damage caused by continuous alternating deformation of the cable's outer protective layer. When the cable is subjected to a single large compression, the elastic support strip can also drive the cable to reset, thereby effectively improving the cable's compressive strength and further enhancing the overall structural strength of the cable.
[0030] In summary, by coordinating the various components within the three-dimensional isolation and protection mechanism and the internal interlocking clamping support mechanism, the heat transfer and external structural protection processes during cable use are optimized. This strengthens the cable's external protection capabilities, directly preventing rodent and ant attacks. Simultaneously, by directionally guiding the heat dissipation process within the cable, it effectively avoids attracting rodents and ants by ensuring the cable's external temperature is higher than the surrounding environment. This reduces the probability of rodents and ants gathering around the cable by utilizing their habits, thus lowering the likelihood of them attacking it. Furthermore, the optimization of the cable's internal structure effectively improves its puncture and compression resistance, thereby enhancing its overall structural strength and operational safety.

[0047] Example: Figure 1-10 As shown, the present invention provides a technical solution, a rodent-proof and ant-proof radial water-blocking cable, including a central conductor 1, an insulating protective inner layer 2 tightly wrapped around the outside of the central conductor 1, and a protective rubber inner ring 3 wrapped around the outside of multiple insulating protective inner layers 2.
[0048] A three-dimensional isolation and protection mechanism 4 is provided on the outer side of the inner protective rubber ring 3. The three-dimensional isolation and protection mechanism 4 is used to protect the outside of the cable and to isolate and guide the moisture that has penetrated into the outer surface of the cable to ensure that the inside of the cable can remain dry.

[0050] A connecting outer rubber ring 401 is provided on the outer side of the inner protective rubber ring 3.

The outer side of the protective metal mesh 405 and the outer side of the protective rubber card 404 are flush with each other.
[0051] A rubber isolation arc-shaped box 406 is snapped onto the side of the outer edge 402 corresponding to the outer side of the connecting outer rubber ring 401. The rubber isolation arc-shaped box 406 is filled with an elastic stretchable silicone capsule 407. Both sides of the elastic stretchable silicone capsule 407 are filled with connecting flexible silicone sheets 408. Protective ceramic arc sheets 409 are evenly and uniformly bonded to the outer arc surface of the connecting flexible silicone sheets 408. An isolation limiting sponge strip 410 is filled in the middle of the inner side of the elastic stretchable silicone capsule 407. Elastic support airbags 411 are filled at both ends of the isolation limiting sponge strip 410 corresponding to the inner position of the elastic stretchable silicone capsule 407. Both the rubber isolation arc-shaped box 406 and the elastic stretchable silicone capsule 407 have cavities inside. There is a gap between the protective ceramic arc sheets 409. Polygonal grooves are evenly provided on the outer side of the protective ceramic arc sheets 409. There is a gap between the outer side of the protective ceramic arc sheets 409 and the inner wall of the elastic stretchable silicone capsule 407.
[0052] Elastic telescopic sleeves 412 are provided at both ends of the elastic telescopic silicone capsule 407 at positions corresponding to the outer side of the elastic support airbag 411. A compression arc-shaped piece 413 is bonded to the top of the elastic telescopic sleeve 412 at a position corresponding to the side of the rubber isolation arc-shaped box 406. Elastic binding tape 414 is bundled around the outer side of multiple compression arc-shaped pieces 413 at positions corresponding to the outer side of the protective rubber card 404. A gap is left between the outer side of the elastic telescopic sleeve 412 and the inner wall of the rubber isolation arc-shaped box 406. A gap is left between the side of the compression arc-shaped piece 413 and the end face of the guide tube on the side of the rubber isolation arc-shaped box 406. The inner side of the elastic binding tape 414 is tightly bonded to the outer side of the compression arc-shaped piece 413 and the protective rubber card 404 by adhesive.
[0053] A small air-guiding tube 415 is fixedly connected to the middle of the outer side of the rubber insulating arc-shaped box 406. Multiple small air-guiding tubes 415 are fixedly connected to a common air-guiding ring 416 at their top ends. A telescopic air-guiding tube 417 is fixedly connected to the middle of the outer top surface of the air-guiding ring 416. A one-way exhaust top box 418 is fixedly connected to the middle of the top end of the telescopic air-guiding tube 417. Flexible connecting arc-shaped films 419 are fixedly connected between the ends of the rubber insulating arc-shaped box 406. The inner cavity of the small air-guiding tube 415 is interconnected with the inner cavity of the elastic telescopic silicone capsule 407. An air-guiding cavity is provided inside the air-guiding ring 416, and a gap is left between the inner ring of the air-guiding ring 416 and the outer side of the protective rubber card 404. A one-way exhaust valve is provided inside the one-way exhaust top box 418, and exhaust rectangles are equidistantly spaced along the circumferential direction on the outer side of the one-way exhaust top box 418. The groove, through the cooperation of the internal components of the three-dimensional isolation and protection mechanism 4, optimizes the protection process of the radial water-blocking cable. The components are installed on the outside of the cable by the protective rubber card 404 and the rubber isolation arc box 406. By strengthening the outer structure of the radial water-blocking cable, the difficulty of rats and termites gnawing on the cable is increased, and the degree and rate of damage caused by rats and termites are reduced. The cable's anti-penetration ability is strengthened by the protective ceramic arc plate 409, which effectively improves the service life of the cable. At the same time, the splicing structure design of the cable's exterior simplifies the inspection and maintenance process during the use of the cable, allowing maintenance personnel to quickly cut and replace damaged parts during the maintenance process, thereby effectively reducing the use and maintenance cost of the cable and further improving the convenience of using the radial water-blocking cable.
[0054] Meanwhile, the internal cavity structure of the rubber-insulated arc-shaped box 406 isolates the inner and outer spaces of the cable, reducing the rate at which heat is directly transferred from the inside of the cable to the outside and the rate at which external moisture directly penetrates into the cable. The semi-open structure of the telescopic air guide tube 417 and the one-way exhaust top box 418 directs the heat and moisture that have penetrated the cable away from the cable body, thereby maintaining the temperature and humidity of the cable. This ensures that the internal temperature and humidity of the cable remain within a suitable range during use, and effectively prevents the heat inside the cable from being directly dissipated into the adjacent space, which would cause a local temperature rise in the surrounding space. This also prevents rodents and ants from gathering around the cable due to their attraction to heat, reducing the probability of the cable being bitten by rodents and ants, effectively improving the overall rodent and ant prevention capabilities of the cable, and further improving the overall service life of the cable.
[0055] The inner protective rubber ring 3 is equipped with an internal staggered snap-fit support mechanism 5. The internal staggered snap-fit support mechanism 5 is used to provide mechanical support for the inside of the cable and to provide buffer protection through the elastic deformation of the internal structure when the cable is subjected to external compression, so as to improve the overall structural strength of the cable.
[0056] The internal interlocking snap-fit support mechanism 5 includes a centrally mounted thin cable 501, a centrally mounted triangular strip 502, a connecting flexible rubber strip 503, an elastic snap-fit shell 504, a central arc-shaped snap-fit groove 505, a dovetail elastic guide plate 506, a filling flexible rubber strip 507, an elastic support rubber strip 508, an installed arc-shaped guide tube 509, a supporting elastic rubber strip 510, a squeezed arc-shaped guide strip 511, a snap-fit arc-shaped piece 512, a flexible silicone buffer layer 513, an internal splicing rubber sleeve 514, a connecting rubber outer sleeve 515, and a filling fan-shaped support airbag 516.
[0057] A centrally mounted thin cable 501 is provided in the middle of the inner side of the protective rubber inner ring 3. A centrally mounted triangular strip 502 is evenly interspersed on the outer side of the centrally mounted thin cable 501. A connecting flexible rubber strip 503 is bonded to the end of the centrally mounted triangular strip 502 at equal intervals. An elastic retainer 504 is bonded to all three sides of the centrally mounted triangular strip 502. A central arc groove 505 is provided in the middle of the inner side of the elastic retainer 504. A dovetail elastic guide plate 506 is provided at the end of the central arc groove 505. A filling flexible rubber strip 507 is filled in the gap of the outer ring of the elastic retainer 504. A telescopic through groove is provided on both sides of the bottom of the elastic retainer 504. The outer arc surface of the elastic retainer 504 is tightly fitted with the outer side of the insulating protective inner layer 2. Elastic deformation grooves are evenly opened on the outer side of the connecting flexible rubber strip 503 at equal intervals.
[0058] Elastic support strips 508 are bonded to both sides of the end face of the elastic housing 504. An installation arc-shaped conduit 509 is bonded to the end of the elastic support strip 508 at the position corresponding to the outer side of the insulating protective inner layer 2. The installation arc-shaped conduit 509 is filled with a support elastic strip 510. The inner arc surface of the installation arc-shaped conduit 509 is tightly fitted to the outer side of the insulating protective inner layer 2, and the outer arc surface of the installation arc-shaped conduit 509 is tightly fitted to the inner side of the protective rubber inner ring 3.
[0059] An extruded arc-shaped guide strip 511 is fixedly connected to the middle of the inner ring of the arc-shaped guide tube 509, and a snap-fit arc-shaped piece 512 is fixedly connected to the middle of the side of the extruded arc-shaped guide strip 511.
[0060] The outer side of the protective rubber inner ring 3 is tightly covered with a flexible silicone buffer layer 513. An internal splicing rubber sleeve 514 is bonded to the outside of the flexible silicone buffer layer 513. A connecting rubber outer sleeve 515 is fitted onto the outside of the internal splicing rubber sleeve 514. A filled fan-shaped support airbag 516 is bonded to the end of the arc-shaped conduit 509 at the position corresponding to the outer side of the connecting flexible rubber strip 503. The sides of the extruded arc-shaped guide strip 511 and the dovetail elastic guide piece 506 correspond to each other. The snap-fit arc-shaped piece 512 and the central arc-shaped slot 505 are correspondingly snapped together. Guide grooves are provided on the outer side of the internal splicing rubber sleeve 514 and the inner side of the connecting rubber outer sleeve 515, through internal staggered... The interlocking support mechanism 5 optimizes the overall protection process of radial water-blocking cables by cooperating with the internal components. The interlocking structure of the internal components maintains the position of the internal components, effectively preventing the cables from being affected by random displacement during use. At the same time, the interlocking of the components on the outside of the internal splicing rubber sleeve 514 effectively strengthens the connection strength between the inner and outer layers of the cable, thereby improving the overall stability of the cable structure and ensuring that the cable can maintain structural stability during continuous operation, further improving the performance of radial water-blocking cables.
[0061] Meanwhile, the spring-loaded snap-fit structure between the elastic retainer 504 and the arc-shaped conduit 509 allows the cable to temporarily maintain its shape after compression when subjected to low-intensity reciprocating compression through the snap-fit of the central arc groove 505 and the snap-fit arc-shaped piece 512. This effectively prevents fatigue damage caused by continuous alternating deformation of the cable's outer protective layer. When the cable is subjected to a single large compression, the elastic support strip 508 can also drive the cable to reset, thereby effectively improving the cable's compressive strength and further enhancing the overall structural strength of the cable.
[0062] The working principle and usage process of this invention: In the actual application of this invention, when radial water-blocking cables are required, the center conductor 1 and the corresponding power transmission cable need to be connected to each other first, and the outer side of the center conductor 1 is protected by the insulating protective inner layer 2, and multiple center conductors 1 are bundled and limited by the protective rubber inner ring 3 to ensure that the radial water-blocking cable can operate normally during use.
[0063] When the radial water-blocking cable is running continuously, it needs to be protected on the outside. The protective rubber card 404 is installed on the outside of the cable by connecting the outer rubber ring 401 and the installation edge 402. The connection strength between the protective rubber card 404 and the installation edge 402 is strengthened by the snap-fit post 403. The protective metal mesh 405 is used to protect the outside of the protective rubber card 404. In this way, the protective metal mesh 405 effectively enhances the overall strength of the outside of the cable, thereby effectively preventing rats and termites from directly gnawing on the outside of the cable and causing rapid damage to the outside of the cable. The overall protective performance of the cable is improved by strengthening the structure.
[0064] Meanwhile, the components are snapped onto the outside of the radial water-blocking cable by the rubber isolation arc box 406, and a rigid protective structure is formed inside the radial water-blocking cable by the cooperation between the flexible silicone sheet 408 and the protective ceramic arc sheet 409 to prevent the cable from being directly damaged by external penetration during use. At the same time, the protective ceramic arc sheet 409 and the isolation limiting sponge strip 410 can absorb and intercept the heat inside the cable to reduce the efficiency of heat transfer from inside the cable to the outside.
[0065] Since radial water-blocking cables are often buried underground or in dark and damp sewers, they are constantly exposed to external moisture. When moisture enters the interior of the rubber insulating arc box 406, it is absorbed and accumulated by the insulating and limiting sponge strip 410. When the heat generated during cable operation heats the interior of the insulating and limiting sponge strip 410, the moisture absorbed inside the insulating and limiting sponge strip 410 absorbs heat and turns into steam. The steam then enters the air-conducting ring 416 through the air-conducting connecting tube 415. The steam inside the air-conducting ring 416 is then discharged through the one-way exhaust top box 418 via the telescopic air-conducting tube 417. In this process of steam discharge, heat dissipation and dehumidification are achieved inside the cable. The ends of the rubber insulating arc box 406 are connected by the flexible connecting arc film 419 to ensure that the rubber insulating arc box 406 can bend and deform synchronously during cable bending.
[0066] When it is necessary to protect the inside of the radial water-blocking cable, the center mounting triangular strip 502 and its components are installed into the inner protective rubber ring 3 by the center mounting thin cable 501, and the end of the center mounting triangular strip 502 is connected by the connecting flexible rubber strip 503 to ensure that each component can be stably installed into the inner protective rubber ring 3.
[0067] When the cable is subjected to external compression, the deformation of the flexible silicone buffer layer 513 can buffer the external extrusion force, and the internal splicing rubber sleeve 514 and the connecting rubber outer sleeve 515 can assist in the connection of the inner and outer structures of the cable, making the connection between the inner and outer layers of the cable tighter.
[0068] When the external compressive force on the cable begins to deform the cable as a whole, the arc-shaped conduit 509 will gradually move towards the end of the elastic retainer 504 under the action of the compressive force. During the movement of the arc-shaped conduit 509, it directly drives the elastic support strip 508 to undergo elastic deformation and store energy. At the same time as the arc-shaped conduit 509 moves, it drives the extrusion arc-shaped guide strip 511 and the snap-fit arc-shaped piece 512 to move closer to the center arc groove 505 and the dovetail elastic guide piece 506. The mutual snap-fit between the center arc groove 505 and the snap-fit arc piece 512 can temporarily maintain the shape of the cable. After the extrusion arc-shaped guide strip 511 and the dovetail elastic guide piece 506 gradually overlap, they will push the dovetail elastic guide piece 506 and the center arc groove 505 outward, thereby simultaneously releasing the constraint on the snap-fit arc piece 512. The elastic force generated by the compression of the elastic support strip 508 will drive the arc-shaped conduit 509 to reset outward, so as to protect the cable from the external compression through elastic deformation.
