Description

Technical Field

[0001] The invention relates to the technical field of radial water-blocking cables, in particular to a rat-proof and ant-proof radial water-blocking cable. Background Art

[0002] Rat- and termite-proof radial water-blocking cables are specialized cables that integrate multiple protective features. Designed for use in complex environments (such as direct underground burial, humid areas, and areas prone to rats and termites), they simultaneously resist rodent (rat) gnawing, termite infestation, and water penetration, ensuring long-term, stable operation of the cables under harsh conditions. To this end, a Chinese patent application, CN201320625824.9, discloses a rat- and termite-proof dual-water-blocking power cable. This patented cable, with radial and longitudinal waterproofing, also prevents rats and termites from biting through the sheath, ultimately extending the life of the buried cable. However, due to the lack of corresponding active connection structure during use, the radial water-blocking cable can only be waterproofed by its own structure during use, and protected from rats and termites by the structure outside the radial water-blocking cable, thereby reducing the overall protection performance of the radial water-blocking cable.

[0014] Compared with the prior art, the present invention has the following beneficial effects: the structure of the present invention is scientific and reasonable, and it is safe and convenient to use: 1. A three-dimensional isolation and protection mechanism is provided. Through the mutual cooperation between the various components within the three-dimensional isolation and protection mechanism, the use and protection process of the radial water-blocking cable is optimized. The various components are installed on the outside of the cable through protective rubber cards and rubber isolation arc boxes. By strengthening the outer structure of the radial water-blocking cable, the difficulty of mice and termites gnawing on the cable is increased, and the degree and rate of damage to the cable caused by mice and termites are reduced. The cable's anti-penetration ability is enhanced by protective ceramic arc sheets, effectively extending the service life of the cable. At the same time, the splicing structure design of the cable's external surface simplifies the inspection and maintenance process during cable use, allowing maintenance personnel to quickly cut and replace damaged parts during the inspection process, thereby effectively reducing the use and maintenance costs of the cable and further improving the convenience of using the radial water-blocking cable. At the same time, the cavity-type structural design inside the rubber-isolated arc box is used to isolate the inner and outer spaces of the cable, thereby reducing the rate at which heat from the inside of the cable is directly transferred to the outside and the rate at which external moisture directly invades the inside of the cable. The semi-open structure of the telescopic air guide tube and the one-way exhaust top box directs the heat inside the cable and the water vapor invading the inside of the cable in a direction away from the cable body, thereby maintaining the temperature and humidity of the cable and ensuring that the temperature and humidity inside the cable are continuously maintained within an appropriate range during use. At the same time, it effectively prevents the heat inside the cable from being directly dissipated to the adjacent space, causing a local temperature rise in the space around the cable, thereby preventing rodents and ants from gathering around the cable due to their thermotaxis, reducing the probability of the cable being bitten by rodents and ants, effectively improving the overall anti-rat and anti-ant capabilities of the cable, and further improving the overall service life of the cable.

[0015] 2. An internal staggered clamping support mechanism is provided. Through the mutual cooperation between the various components within the internal staggered clamping support mechanism, the overall protection process of the radial water-blocking cable during use is optimized. Through the clamping structural design of the various components within the cable, the position of the internal components of the cable is maintained, effectively preventing the normal use of the cable from being affected by the random displacement of the internal components during use. At the same time, the mutual cooperation between the various components outside the internal splicing rubber sleeve effectively strengthens the connection strength of the inner and outer layer components of the cable, thereby effectively improving the stability of the overall cable structure, ensuring that the cable can maintain structural stability during continuous operation, and further improving the performance of the radial water-blocking cable; At the same time, the resilient snap-fit structure design between the elastic housing and the installed arc-shaped conduit allows the cable to temporarily maintain its shape after extrusion when subjected to external low-intensity reciprocating extrusion through the clamping of the central arc slot and the clamping arc piece, effectively preventing fatigue damage caused by continuous alternating deformation of the cable's external protective layer. When the cable is subjected to a single large-scale extrusion, the elastic support strip can also be used to drive the cable to reset, thereby effectively improving the cable's compressive resistance and further improving the overall structural strength of the cable.

[0016] In summary, through the mutual cooperation between the components of the three-dimensional isolation protection mechanism and the internal staggered clamping support mechanism, the heat transfer and external structure protection process during the use of the cable are optimized, and the cable is directly protected from the biting of rats and ants by strengthening the protection ability of the outside. At the same time, by guiding the heat dissipation process inside the cable in a directional manner, it is effectively avoided that the temperature outside the cable is higher than the ambient temperature and attracts rats and ants to gather. By utilizing the living habits of rats and ants, the probability of rats and ants gathering around the cable is reduced, thereby reducing the probability of rats and ants biting the cable. At the same time, through the optimization of the internal structure of the cable, the cable's puncture resistance and extrusion resistance are effectively improved, thereby effectively improving the overall structural strength and safety of the cable.

A gap is provided between the protective ceramic arc sheets 409, and polygonal grooves are evenly provided on the outside of the protective ceramic arc sheets 409. There is a gap between the outer sides of the protective ceramic arc sheets 409 and the isolation and limiting sponge strips 410 and the inner wall of the elastic and telescopic silicone capsule 407. Elastic telescopic sleeves 412 are provided at the outer sides of the elastic support airbags 411 at both ends of the elastic telescopic silicone capsule 407.

Then, by strengthening the outer structure of the radial water-blocking cable, the difficulty of mice and termites gnawing on the cable is increased, and the degree and rate of damage to the cable by mice and termites are reduced. The cable's anti-penetration ability is enhanced by the protective ceramic arc sheet 409, which effectively increases the service life of the cable. At the same time, the spliced structural 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 inspection process, thereby effectively reducing the use and maintenance costs of the cable and further improving the convenience of using the radial water-blocking cable. At the same time, the internal cavity structure design of the rubber isolation arc box 406 is used to isolate the internal and external spaces of the cable, so as to reduce the rate at which the heat inside the cable is directly transferred 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 transfers the heat inside the cable and the water vapor that penetrates into the cable in a direction away from the cable body, thereby maintaining the temperature and humidity of the cable and ensuring that the temperature and humidity inside the cable are continuously maintained within a suitable range during use. At the same time, it effectively prevents the heat inside the cable from being directly dissipated to the adjacent space, causing a local temperature rise in the space surrounding the cable, thereby preventing rodents and ants from gathering around the cable due to their thermotaxis, reducing the probability of the cable being bitten by rodents and ants, effectively improving the overall anti-rat and anti-ant capabilities of the cable, and further improving the overall service life of the cable. An internal staggered clamping support mechanism 5 is provided inside the protective rubber inner ring 3. The internal staggered clamping support mechanism 5 is used to provide mechanical support to the inside of the cable and to provide buffering protection through elastic deformation of the internal structure when the cable is squeezed from the outside, thereby improving the overall structural strength of the cable. The internal staggered clamping support mechanism 5 includes a central mounting thin cable 501, a central mounting triangular bar 502, a connecting flexible rubber strip 503, an elastic clamping shell 504, a central arc clamping groove 505, a dovetail elastic guide piece 506, a filling flexible rubber strip 507, an elastic supporting rubber strip 508, an installation arc guide 509, a supporting elastic rubber strip 510, an extruded arc guide bar 511, a clamping arc piece 512, a flexible silicone buffer layer 513, an internal splicing rubber sleeve 514, a connecting rubber cover 515 and a filling fan-shaped supporting airbag 516; A central installation cord 501 is provided in the middle of the inner side of the protective rubber inner ring 3, and a central installation triangle bar 502 is evenly and evenly installed on the outer side of the central installation triangle bar 501. A connecting flexible rubber strip 503 is evenly bonded to the end of the central installation triangle bar 502.

The mutual cooperation between the components inside the card-type support mechanism 5 optimizes the overall protection process of the radial water-blocking cable during use. The card-type structural design of the components inside the cable maintains the position of the internal components of the cable, effectively preventing the internal components from being randomly displaced during use and affecting the normal use of the cable. At the same time, the mutual cooperation between the components outside the internal splicing rubber sleeve 514 effectively strengthens the connection strength of the inner and outer layer components of the cable, thereby effectively improving the stability of the overall structure of the cable, ensuring that the cable can maintain structural stability during continuous operation, and further improving the performance of the radial water-blocking cable. At the same time, through the resilient snap-fit structure design between the elastic card shell 504 and the installation arc-shaped guide tube 509, when the cable is subjected to external low-intensity reciprocating extrusion, the cable can temporarily maintain its shape after extrusion through the snap-fit connection between the central arc slot 505 and the snap-fit arc-shaped piece 512, effectively preventing the external protective layer of the cable from continuous alternating deformation and fatigue damage. When the cable is subjected to a single large-scale extrusion, the elastic support strip 508 can also drive the cable to reset, thereby effectively improving the cable's compressive resistance and further improving the overall structural strength of the cable.

[0021] Working principle and usage process of the present invention: In actual application, when a radial water-blocking cable is needed, the central conductor 1 and the corresponding transmission cable need to be connected to each other first, and the outer side of the central conductor 1 is protected by the insulating protective inner layer 2, and multiple central 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; During continuous operation of the radial water-blocking cable, its outer side needs to be protected. The protective rubber clip 404 is installed on the outer side of the cable by connecting the outer rubber ring 401 with the mounting edge 402. The connection strength between the protective rubber clip 404 and the mounting edge 402 is strengthened by the clamping column 403. The outer side of the protective rubber clip 404 is protected by the protective metal mesh 405. The protective metal mesh 405 effectively enhances the overall strength of the outer side of the cable, thereby effectively preventing rats and termites from directly gnawing on the outer side of the cable over a large area and causing rapid damage to the outer side of the cable. The overall protection performance of the cable is improved by strengthening the structure. At the same time, the components are clamped to the outside of the radial water-blocking cable through the rubber isolation arc box 406, and a hard protective structure is formed inside the radial water-blocking cable by the mutual 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. The protective ceramic arc sheet 409 and the isolation and limiting sponge strip 410 can absorb and intercept the heat inside the cable to reduce the efficiency of heat transfer from the cable to the outside. Since radial water-blocking cables are mostly buried underground or in dark and humid sewers during use, radial water-blocking cables will be continuously invaded by external moisture during use. When moisture invades the internal area of the rubber isolation arc box 406, the invading moisture will be absorbed and concentrated by the isolation limiting sponge strip 410. When the interior of the isolation limiting sponge strip 410 is heated by the heat generated during the operation of the cable, the moisture adsorbed inside the isolation limiting sponge strip 410 will absorb the heat and turn into steam and enter the interior of the air guiding connecting hoop 416 through the air guiding connecting small tube 415. Then, the steam inside the air guiding connecting hoop 416 is discharged through the one-way exhaust top box 418 via the telescopic air guiding small tube 417, thereby achieving heat dissipation and dehumidification inside the cable in the process of steam discharge, and the end of the rubber isolation arc box 406 is connected by the flexible connecting arc film 419 to ensure that the rubber isolation arc box 406 can bend and deform synchronously during the bending process of the cable. When the inside of the radial water-blocking cable needs to be protected, the central mounting triangle bar 502 and the components thereon are mounted inside the protective rubber inner ring 3 via the central mounting thin rope 501, and the ends of the central mounting triangle bar 502 are connected via the connecting flexible rubber strip 503 to ensure that the components can be stably mounted inside the protective rubber inner ring 3; When the cable is squeezed from the outside, the deformation of the flexible silicone buffer layer 513 can buffer the external squeezing force, and the internal splicing rubber sleeve 514 and the connecting rubber outer sleeve 515 can assist in connecting the inner and outer structures of the cable, making the connection between the inner and outer layers of the cable more tightly. When the external extrusion force exerted on the cable begins to cause the cable to deform as a whole, the installation arc-shaped conduit 509 will gradually approach the end of the elastic card shell 504 under the action of the extrusion force, and directly drive the elastic supporting rubber strip 508 to elastically deform and store energy during the movement of the installation arc-shaped conduit 509, and at the same time as the movement of the installation arc-shaped conduit 509, drive the extrusion arc-shaped guide bar 511 and the card-connecting arc piece 512 to approach the inside of the central arc card slot 505 and the dovetail elastic guide piece 506, and the shape of the cable can be temporarily maintained by the mutual card connection between the central arc card slot 505 and the card-connecting arc piece 512. After the extrusion arc-shaped guide bar 511 and the dovetail elastic guide piece 506 gradually overlap, the dovetail elastic guide piece 506 and the central arc card slot 505 will be stretched outward, thereby simultaneously canceling the constraint on the card-connecting arc piece 512, and the installation arc-shaped conduit 509 will be reset outward by the elastic force generated by the compression of the elastic supporting rubber strip 508, so as to protect the outside of the cable from extrusion through elastic deformation.
