Description

Technical Field

[0001] The utility model relates to the field of cable gluing, in particular to a cable gluing wire passing module and device. Background Art

[0002] 3000mm 2 During the stranding process of submarine cable conductors, it is necessary to coat water-blocking silica gel on the surface. The commonly used water-blocking silica gels for high-voltage cables are mainly two-component semiconductive water-blocking glue and one-component semiconductive water-blocking glue. Both materials are composed of polymers and conductive filling materials, and the finished product is a viscous colloid.

[0003] Silicone rubber is an elastomer formed by using linear polyorganosiloxane as the base polymer (raw rubber), adding cross-linking agents, reinforcing fillers and other compounding agents, and undergoing compounding and vulcanization. It can be used in a very wide temperature range, from -100°C to 315°C, which is beyond the reach of any other elastomer. At the same time, it also has excellent properties such as weather aging resistance, electrical insulation, hydrophobicity, anti-adhesion, and biocompatibility. Weather aging resistance is its important feature. It is estimated through experiments that it can be used outdoors for 100 - 150 years. However, due to the high viscosity of the water-blocking glue, manual coating is time-consuming and laborious and cannot ensure uniform coating.

[0004] Therefore, those skilled in the art are committed to developing a cable gluing wire passing module and device to reduce the labor intensity of workers and improve the uniformity of the water-blocking glue on the cable surface. Summary of the Utility Model

It should be noted that in the description of the present utility model, the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific manner, and therefore cannot be construed as a limitation of the present utility model. The terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0026] As Figure 1-7 shown, a cable glue coating wire passing module includes a wire passing die base 4. A first through hole 5 is formed in the wire passing die base 4. A first wire passing die 6 is arranged in the first through hole 5. A second through hole 7 is formed at the central position of the first wire passing die 6, and the second through hole 7 horizontally penetrates the first wire passing die 6.

[0027] The wire passing die base 4 serves as the installation foundation for the first wire passing die 6. A horizontally extending first through hole 5 is formed in the wire passing die base 4. The first through hole 5 completely penetrates the base 4 of the first wire passing die 6. A first wire passing die 6 is arranged in the first through hole 5. The outer side wall of the first wire passing die 6 is tightly connected to the first through hole 5. A convex rib is arranged at the front end of the first wire passing die 6, and the convex rib abuts against the front side wall of the wire passing die base 4 to fix the position of the first wire passing die 6 in the wire passing die base 4. A second through hole 7 is formed at the central position of the first wire passing die 6, and the second through hole 7 horizontally penetrates the first wire passing die 6. The central lines of the first through hole 5 and the second through hole 7 coincide. The second through hole 7 is mainly used for the cable to pass through and can be designed according to the cable size.

[0028] In this embodiment: An annular glue storage groove 8 is formed on the outer side wall of the first wire passing die 6. A plurality of glue inlet holes 9 are formed in the circumferential bottom of the annular glue storage groove 8. The second through hole 7 is communicated with the annular glue storage groove 8 through a plurality of glue inlet holes 9.

[0029] An annular glue storage groove 8 is formed on the outer side wall of the first wire passing die 6. The annular glue storage groove 8 can adopt a "U" - shaped or "V" - shaped structure. A plurality of glue inlet holes 9 are formed at the bottom of the annular glue storage groove 8. The preferred number of the glue inlet holes 9 is 6. The second through - hole 7 is communicated with the annular glue storage groove 8 through the glue inlet holes 9. The silicone rubber in the glue storage groove 8 can flow into the second through - hole 7 along the glue inlet holes 9, thereby coating the silicone rubber on the surface of the cable passing through the second through - hole 7.

[0030] In this embodiment: A second wire passing die 10 is arranged behind the first wire passing die 6. A third through - hole 11 extending in the horizontal direction is formed on the second wire passing die 10. The third through - hole 11 completely penetrates the second wire passing die 10. The central lines of the second through - hole 7 and the third through - hole 11 coincide.

[0031] A second wire passing die 10 is arranged behind the first wire passing die 6. When the cable passes through the first wire passing die 6, the surface of the cable has been coated with silicone rubber. Affected by gravity, the silicone rubber at the top of the first through - hole 5 can reach the surface of the cable faster through the glue passing holes 9, resulting in more silicone rubber at the top of the cable than at the bottom of the cable. When the cable passes through the second wire passing die 10, the excess silicone rubber at the top of the cable flows downward along the surface of the cable. At this time, the second wire passing die 10 can perform secondary treatment on the silicone rubber on the surface of the cable, scraping off the excess silicone rubber on the surface of the cable to make the coating of the silicone rubber more uniform.

[0032] In this embodiment: The wire passing die base 4 includes an upper base 401 and a lower base 402. The upper base 401 and the lower base 402 are detachably connected. A fourth through - hole 12 is formed on the upper base 401. The fourth through - hole 12 extends vertically upward through the upper base 401. A high - pressure oil pipe 2 is arranged in the fourth through - hole 12. One end of the high - pressure oil pipe 2 is inserted into the annular glue storage groove 8 through the fourth through - hole 12, and the relative other end is connected to a glue storage tank 3.

[0033] The upper base 401 and the lower base 402 are detachably connected. Specifically, bolts or other methods can be used for connection. During the continuous production of the cable conductor, it is convenient to replace. A fourth through - hole 12 extending vertically upward is formed on the upper base 401. The fourth through - hole 12 completely penetrates the upper base 401. A high - pressure oil pipe 2 is arranged in the third through - hole 11. One end of the high - pressure oil pipe 2 is inserted into the annular glue storage groove 8 through the third through - hole 11, and the relative other end is connected to a glue storage tank 3. The silicone rubber in the glue storage tank 3 can flow into the annular glue storage groove 8 along the high - pressure oil pipe 2.

[0034] A cable glue coating device includes the cable glue coating wire passing module as described above, and further includes a support base 1. A glue storage box 13 is arranged at the top of the support base 1. The wire passing module is installed at the inner bottom of the glue storage box 13. One end of the high - pressure oil pipe 2 is connected to the upper base 401, and the relative other end is connected to the glue storage tank 3.

[0035] The support base 1 is fixedly installed at the top of the support base 1 as the installation base of the glue storage box 13. The glue storage box 13 can recycle the overflowed silicone rubber to ensure the cleanliness of the on-site environment. The recycled silicone rubber can also be reused after being processed, avoiding waste. The wire passing module is installed at the inner bottom of the glue storage box 13. One end of the high-pressure oil pipe 2 is connected to the upper base 401, and the opposite end is connected to the glue storage tank 3. The silicone rubber in the glue storage tank 3 can flow into the annular glue storage groove 8 along the high-pressure oil pipe 2.

[0036] In this embodiment: The glue storage box 13 is detachably connected to the support base 1.

[0037] The glue storage box 13 can be bolted to the top of the support base 1, which is convenient for taking the glue storage box 13 and collecting the overflowed silicone rubber in the glue storage box 13.

[0038] In this embodiment: A nitrogen pressurizing device 14 is provided on the glue storage tank 3, and a throttle valve 15 is provided on the high-pressure oil pipe 2.

[0039] Since the viscosity of the silicone rubber is relatively large, in order to ensure continuous supply of the silicone rubber, the silicone rubber needs to be pushed by nitrogen as the power. Therefore, a nitrogen pressurizing device 14 is provided on the glue storage tank 3. In order to further control the output volume of the silicone rubber, a throttle valve 15 is provided on the high-pressure oil pipe 2, and the output volume of the silicone rubber can be further controlled by adjusting the valve.

[0040] In this embodiment: The first wire passing die 6 and the second wire passing die 10 are made of high wear-resistant nylon material.

[0041] The first wire passing die 6 and the second wire passing die 10 can be made of materials such as wear-resistant nylon, self-lubricating super wear-resistant nylon, graphite nylon, carbon fiber nylon, nylon / molybdenum disulfide alloy, nylon / polytetrafluoroethylene alloy, and fiber-reinforced nylon and PTFE composite super wear-resistant nylon, which can extend the service life of the first wire passing die 6 and the second wire passing die 10.

[0042] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field according to the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
